grains by atomic force microscopy and by dye adsorption. Journal of Imaging
Science and Technology, 40 (3), 185-188.
Abstract: The average thickness of tabular silver bromide grains can be calculated from
the magnitude of the specific dye adsorption if some estimate of the average grain
diameter is available. Using 1,1’-diethyl a, 2’-cyanine chloride as the dye, we related
the calculated grain thicknesses, in the range from 30 to 150 nm, to data from atomic
force microscopy. To bring these two methods into agreement, a limiting molecular
area of 0.62±0.01 nm2 had to be assigned, which is 10% higher than the reported
value for octahedral {111} faces. Dye adsorption gives a result close to the number
average thickness of the grains, unless there exists a significant correlation between
grain thickness and diameter.

Abstract: Many factors may affect the heavy metals sorption on natural zeolites among
them the temperature, for this reason in this paper the cadmium retention behavior on
Mexican zeolitic rich tuff as a function of temperature is considered. The kinetic and
the isotherms were determined at 303, 318, and 333 K, the remaining cadmium in the
solution samples was analyzed by atomic absorption spectrometry. The
pseudo-second order rate constant, k, as well as the apparent diffusion coefficients
were calculated from the cadmium uptake by the zeolitic rock as a function of the
contact time and temperature, the highest amounts were found for the experiments
done at 333 K. The maximum cadmium adsorption capacity by the zeolitic material
was 12.2 mg Cd2+/g at 318 K corresponding to 20% of the effective ion exchange
capacity of the Chihuahua zeolitic rock. In order to explain the cadmium sorption
behavior different kinetics and isotherm models were considered.

Abstract: Recent works show that modified natural zeolites improve the remotion of
anionic or non-polar organic pollutants from water. In this work the arsenic sorption
from aqueous solutions onto clinoptilolite-heulandite rich tuffs modified with
lanthanum, hexadecyltrimethylammonium or iron was investigated considering the
arsenic chemical species and the pH of the arsenic solutions.
Clinoptilolite-heulandite rich tuffs were characterized by scanning electron
microscopy and X-ray diffraction analysis. The elemental composition of the zeolitic
samples was also determined. According to the Langmuir isotherm model the
arsenic(V) sorption capacity of the zeolites was 75.4 g As/g at pH 3, 3.9 g As/g at
pH 5 and 53.6 g As/g at pH 6, for the lanthanum, HDTMA and iron modified
clinoptilolite-heulandite rich tuff from Chihuahua (Mexico), respectively. In general,
the results suggested that the arsenic retention depends on the precedence of zeolitic
material, the nature of arsenic chemical species, pH as well as the characteristics of
modified natural zeolites. In this work the arsenic adsorption mechanisms are also
discussed.

Abstract: The sorption of beta-cyclodextrin polymer (beta-CDP) and
gamma-cyclodextrin polymer (gamma-CDP) toward 2,4-dichlorophenol (2,4-DCP)
in aqueous solutions was investigated. The influence of sorption conditions including
initial 2,4-DCP concentration, contact time and pH on sorption capability were
discussed. Their sorption behaviors for 2,4-DCP were conducted and it was found
the sorption kinetics followed the Ho and McKay equation and the film diffusion was
the rate-determined step. The sorption isotherm can be correlated to Freundlich
model and the sorption capacity on beta-CDP was much larger than that on
gamma-CDP. The maximum sorption capacity of 2,4-DCP for beta-CDP was
measured to be 0.16 mmol/g with the initial concentration at 0.67 mmol/L at 288 K.
The CDPs were easily recovered by ethanol as washing solvent and they could be
used as a kind of recyclable sorbents.

Abstract: Carbon slurry waste from fertilizer plant and blast furnace slag, dust and
sludge from steel plant have been investigated after some processing as adsorbents
for the removal of Methylene blue dye. The results have indicated that the
carbonaceous adsorbent prepared from carbon slurry waste of fertilizer industry has
high porosity and much larger surface area (380 m2/g) as compared to other three
adsorbents (4-28 m2/g). This has resulted in large adsorption of the dye (92 mg/g) on
this adsorbent whereas the adsorption on the other three adsorbents is poor (2.1-6.4
mg/g). The adsorption of Methylene blue on carbonaceous adsorbent conforms to
Langmuir model, and is a first order process and pore diffusion controlled. A
comparison of its performance with standard activated charcoal sample shows that its
efficiency is 45% as compared to standard sample and thus can be used as alternative
in view of its low cost.

The sorption of both the forms of chromium by the resin follows a second order rate
law with rate constant values of 0.013 and 0.100 mmol-1 min-1 for Cr-III and Cr-VI
respectively. The recovery of both the forms of the chromium was quantitative by

Abstract: The present study reports a systematic ad sorption of lead(II) onto hydrated

column methods. The particle size of HTO used is in the range 140 to 290 m. Effect
of pH, contact time for kinetics, adsorption isotherm etc. and breakthrough with
influent lead(II) concentration, flow rate and bed depth variations studies are
reported by batch and column methods, respectively. The optimum pH range found
for maximum lead(II) sorption is 5.0 to 6.0. The adsorption data fit the tested
adsorption isotherms in the following order: Langmuir>Freundlich>Temkin. Three
kinetic models viz. the power function, the simple Elovich and the pseudo
second-order are tested for fitting the experimental equilibrium data. Both the power
function and the simple Elovich equations are found to fit best at lower adsorbate
concentrations. No remarkable influence was found on adsorption of lead(II) by the
cations and anions tested. 0.5 M HNO3 was found to be an efficient agent, which
could desorb 90.0 to 92.0% of the adsorbed lead(II) from the saturated adsorbent.

Abstract: A carbon sorbent derived from the fruit shell of Indian almond (Terminalia

aqueous solution. Maximum uptake occurred in the pH range of 5 to 6. The kinetics
of sorption conformed. well to modified second order model among the other kinetic
models (pseudo first order,and pseudo second order) tested. The Langmuir isotherm
defined the equilibrium data more precisely compared to Freundlich isotherm and the
monolayer sorption capacity determined was 94.43 mg g-1 at pH 5.0 and at room
10
temperature (305 K). Sorption capacity increased with increase in temperature and
the thermodynamic parameters, H, S and G, indicated the Hg-II sorption to be
endothermic and spontaneous with a greater affinity of Hg-II species for the sorbent.
About 60% of Hg-II was recovered from the spent carbon at pH 1.0, while 94% was
desorbed using 1.0% KI solution.

Abstract: Separation and preconcentration of two forms of chromium viz. Cr-III and

anchored onto polystyrene-divinylbenzene (8%) by azo (-N=N-) function. The
maximum exchange capacity of Cr-III was found to be 0.6718 mmol g-1 at pH 6.5

Cr-VI onto resin follows a second order kinetics with rate constant values of 0.047
and 0.410 mmol-1 min-1 for Cr-III and Cr-VI respectively. The two species Cr-III and
Cr-VI are eluted completely by 3 M and 4 M HCl respectively. The detection limits
of 4.3 and 5.1 ng ml-1. for Cr-III and Cr-VI were achieved. The optimum flow rate,
sample breakthrough volume or column operation for. Cr-III and Cr-VI species were
found to be 1.2 ml min-1 and 3000 ml respectively. Finally the developed method
using this resin was applied for determination of these two species in synthetic binary

Abstract: Hen eggshell powder has been found to be a potential adsorbent for the
removal of copper from aqueous medium. A detailed adsorption study of Cu(II) on
eggshell powder was investigated. Batch adsorption study was carried out as a
function of solute concentration, contact time, adsorbent dose, pH and temperature.
The experimental data were analysed using Langmuir and. Freundlich isotherm
models. It was found that these two isotherm models fitted well. pH variation study
revealed that the adsorption increased with the increase in pH of the solution.
Maximum uptake of Cu(II) from the solution by the eggshell was found to be 51.67
mg g-1 at 6 mg L-1 of initial Cu(II) concentration. Adsorption data were analyzed
using kinetic models, Lagergren’s first order and pseudo second order. It was
observed that pseudo second order represented the best correlation. Thermodynamic
study revealed that the sorption of Cu(II) by hen eggshell powder is an endothermic
13
process showing increase in sorption at higher temperatures. The negative values of
standard free energy (ΔGº) indicate the spontaneity of the sorption process. The
present investigation emphasizes that eggshell powder may be utilized as an efficient
material for the removal of Cu(II) from aqueous solution.

Abstract: The study assesses the suitability of inexpensive leaf adsorbents to effectively
remediate fluoride-contaminated water. The efficiency of the sorption of fluoride ion
is affected by pH, contact time, adsorbent dose, type and size of adsorbents and
initial fluoride ion concentration. The adsorption equilibrium is well correlated by
Freundlich and Langmuir models. Treated leaf powder was studied at various pHs (2,
4, 6 and 8) with a series of aqueous solutions containing 2, 3, 5, 6, 8, 10, 12, and 15
mg F–/l. At the highest F- ion concentration (15 mg/l), the F– ion level in the effluent
gradually decreased to 0 mg/l within 180 min at 29±0.5°C when the dose of
adsorbent is 10 g/l in a sample of 50 ml volume. With lower F– ion concentrations (2
mg/l) in the feed solutions the fluoride ion concentration steadily decreased reaching
0 mg/l after 150 min. Langmuir isotherm fits well for defluoridation of water using
leaf powder.

Abstract: Removal of copper from wastewater by ferric, limestone coagulation and
polymer flocculation followed by lamellar sedimentation was studied at laboratory
scale. From jar test experiments. the optimum dosages of inorganic coagulant and
polymer flocculant were Fe(III) 50 mg, L and 0.1% SA 407 Solution 0.5 similar to
1.0 mL, L, respectively. A novel process was developed for continuous copper
removal. in which a limestone aeration bed. a rapid-mixing tank, a slow-mixing tank,
and a sedimentation tank with lamellae were applied systematically. In the limestone
aeration bed alkalization and coprecipitation of copper ion with Fe(III) were
performed cocurrently. Flocculation of the ferric hydroxide, copper aggregates was
performed efficiently with a minute quantity of the polymer flocculant in the mixing
tank. The flocs were settled down in the sedimentation tank with lamellae and were
separated from treatment water. The pH was maintained around 7.6 during the whole
process and the performance results of the process showed copper removal efficiency
18
over 99%. Copper removal efficiency was dependent on hydraulic retention time
(HRT) and especially the HRT in the limestone aeration bed was a limiting factor.

Abstract: This paper presents a surface reaction rate model that can be used to describe
the batch adsorption of metal ions onto unconventional adsorbent materials. Kinetic
data of Cu(II) and Ni(II) adsorption on oil palm ash were compared with predictions
of the theoretical model following determination of its parameters from small-scale
experiments. In all cases studied it was possible to obtain excellent agreement
between the experimental data and predicted results throughout the whole time
course of adsorption. The apparent success of the model in accounting for
experimental observations suggests that it can be used for the design and
optimization of stirred batch adsorption systems.

Abstract: Heavy metal adsorption by zeolite synthesized from fly ash was investigated.
Approximately 90% of the lead and copper ions originally present in the solution
were adsorbed onto the adsorbent within about 30 min after the start of the
adsorption and an equilibrium was reached within 2 h. The favorable pH region was
from 5 to 6. The maximum adsorption capacities obtained using the Langmuir model
were about 1.29 mmole/g for lead and 1.16 mmole/g for copper. The capacity for
lead removal by the synthesized zeolite was dependent on the ligand type and
concentration. In a binary adsorption system, the influence of copper ions on the lead
ion adsorption was small, yet the copper ion adsorption was significantly decreased
when lead ions were present.

Abstract: The heavy metal adsorption and desorption characteristics of Trichoderma

adsorption by NaOH treatment, and the concentrations of cadmium and copper ions
were analyzed using an atomic absorption spectrophotometer. The desorption
capabilities of HNO3, HCl, CH3COOH, ddH2O, NE4OH, NaOH, and NaCl were also
examined. The acidic desorbents removed more than 90% of the loaded cadmium
from the cells. A higher fraction of the cadmium ion than the copper ion was
recovered by desorption. At a very low pH (pH 1-2), the adsorption of heavy metals
decreased, and the cells could be reused after desorption and NaOH treatment.

Abstract: Quaternized sawdust modified with N-(3-chloro-2-hydroxypropyl)
trimethylammonium chloride (CHMAC) was evaluated for its ability to remove two
reactive dyes (Reactive Blue 19 & Reactive Red 4) from aqueous solution. The
adsorption capacities of Reactive Blue 19 and Reactive Red 4 on quaternized
sawdust were approximately five and sixteen times higher than that of activated
carbon (F-400), respectively. Moreover, adsorption on quaternized sawdust was
hardly affected by salt concentration. It was also found that the degree of sawdust
quaternization has a good linear relationship with the maximum adsorption capacity.
This indicates that the electrostatic interaction between anionic sites in reactive dyes
and quaternized cationic sites in sawdust is of primary importance in terms of the
adsorption characteristics of the two reactive dyes. However, the desorption test of
dyes adsorbed on quaternized sawdust showed poor performance in NaOH and NaCl
solution, suggesting additional undefined binding forces

Abstract: This research was carried out to identify color-causing materials in the coke
plant wastewater and to suggest a method to remove color from the coke wastewater
20
treatment plant. For this purpose, coke wastewater treatment process in P company
was investigated. The highest difference in color intensity between apparent and true
color was observed in ammonia (24%), and the lowest in ammonia washer (7%).
Removal efficiency of apparent and true color measured in the secondary clarifier
effluent was 38 and 34%, respectively. Color caused by colloidal particles of which
size was larger than 0.45 mum and humin was negligible. Maximum and minimum
contribution of humic acid in causing F color and other soluble organic materials in
causing P color were 23, 24 and 79, 61%, respectively. Maximum and minimum
contribution of tannin and lignin in causing P” color were 88 and 79%, respectively.
Thus, tannin and lignin are important materials in causing P” color in P” color.
Organic materials with molecular weight ranging from 5000 to 1000 were detected in
the equalization tank effluent, while those with molecular weight ranging from 2500,
800 and 400 were detected in the secondary clarifier effluent.

Abstract: Chitin and chitosan, which are found in crustacea, mollusca, and fungus, are
natural polymers. The average molecular weight and the degree of deacetylation of
the chitosan used were found to be 8.2105 and 85%, respectively. The chitosan
solution was prepared by dissolving chitosan powder into a 2 wt% aqueous acetic
acid solution. Sodium hydroxide solution was used as a gelation agent. Spherical
chitosan beads for of fixed-bed experiments were made by the sol-gel method.
Single-component isotherms Cu2+ and Cd2+ fit well with the Sips isotherm. The
adsorption behavior in a fixed-bed was observed in terms of the flow rates for
single-and binary-component systems. The adsorption affinity Of Cu2+ onto chitosan
beads is larger than that of Cd2+ In the binary system, the breakthrough data of the
lower-selectivity ion showed an excess concentration; the exit concentration is higher
than the initial concentration at the inlet. Intraparticle diffusion is explained by the
pore diffusion mechanism. Adsorption dynamics of Cu2+ and Cd2+ in a fixed- bed can
be simulated by LDFA (linear driving force approximation).

Abstract: In this work, the removal of zinc-cyanide complexes using dead cells of
brewery yeast obtained from a beer brewery was studied. The particle size, surface
area, and pore radius of the biomass used in this study were 0.075 similar to 0.150
mm, 1.79 m2/g, and 21.1 Angstrom, respectively. The Langmuir isotherm
represented the equilibrium data for the zinc ion very well, and the adsorption
capacity for zinc ions was 2.3 mg/g at pH 12. The adsorption rate increased upon
increasing the biomass concentration, and a first-order kinetic model represented our
experimental data very well. The peaks in the FT-IR spectra of the biosorbent used
for zinc adsorption were substantially lower than those of the raw biosorbent. This
change of peak size can be interpreted as the result of weakened bond structure of the
biomass that is due to the reaction between the zinc ions and the functional groups of
the biomass.

Abstract: Pine (Pinus densiflora) bark activated with zinc chloride was prepared and
characterized by the nitrogen adsorption method. The impregnated amount of zinc
chloride on the pine bark and the activation temperature of the composite were
important for the preparation of activated carbon having a high surface area. Large
particles of bark led to a slight reduction in surface area of the prepared activated
carbon. The impregnation of zinc chloride on the bark was effective in enhancing the
BET surface area. The largest surface area (2280 m2, g) of an activated carbon was
obtained through the activation of the bark with 200% zinc chloride impregnation at
450 degreesC for 2 h, but further increases in the impregnated amount, temperature,
and time did not have any positive effects on increasing the surface area. The average
radii of the activated carbons were mostly less than 20 Angstrom.

Abstract: Adsorption of chromate anions was performed using cetyltrimethylammonium
bromide (CTABr)-modified FAU and MCM-41 molecular sieves. Because the
CTA(+) ion is too large to enter into the internal surface of faujasite (FAU), the
adsorption of the ammonium ion occurred only on the external surface. On the other
hand, the pore sizes of MCM-41 are large enough to accommodate this cationic
surfactant. These materials were characterized using XRD, TG, SEM, EDX, and
nitrogen adsorption and desorption data. While the unmodified FAU and unmodified
MCM-41 had no affinity for chromate anions, the surfactant-modified molecular
sieves exhibited significantly enhanced efficiencies for the removal of the oxyanion
from aqueous solution. The adsorption of chromate on the surfactant-modified
molecular sieves seems to result from a combination of entropic, Coulombic, and
hydrophobic effects.

Abstract: To establish the feasibility of the removal of lead using chitin, adsorption
characteristics were investigated at various temperatures and concentrations. The
adsorption characteristics of chitin were analyzed by determining its adsorption
equilibrium, kinetics, and thermodynamic properties. The data gathered favor the
Langmuir over the Freundlich model. The adsorption capacity of the
surface-modified natural chitin for Pb(II) removal increased significantly when the
adsorbent was treated using the xanthation method. The homogeneous surface
diffusion model described the adsorption kinetic data well and can be used to predict
the chitin performances; therefore, it could be helpful for design considerations.
Under the steady-state reaction conditions, the change in Gibbs free energy (G)
ranged from -19.03 to -21.50 kJ/mol, and the enthalpy (H) and entropy (S)
changes were 16.54 kJ/mol and 0.124 kJ/mol/K, respectively; i.e., a higher
temperature favors a spontaneous Pb(II) adsorption by chitin when using the
xanthation method. Thermodynamic calculations indicate that the adsorption of lead
on the adsorbents was spontaneous and endothermic. Application of the chitin
modified with the xanthation method to the removal of Pb(II) metals from
wastewater is expected to be economical and effective.

Abstract: Aluminum(Al) was impregnated onto lignocellulosic materials (Juniperus
24
monosperma) to develop inorganic/organic hybrid adsorbents for removing
orthophosphate from water. Surface modification of the bio-renewable materials by
impregnation of an inorganic moiety extended the applicability from heavy metal
removal to anion removal in water. Al components were loaded onto juniper wood,
an organic substrate, under three different pH conditions (pH 3.0, 3.7, and 4.7)
resulting in three Al-impregnated adsorbents, named Al/JW01, Al/JW02, and
Al/JW03, respectively. Adsorption kinetic experiments, performed with a pH of
5.0±0.1 and an initial phosphorus, P, concentration of 10 ppm, demonstrated
orthophosphate adsorption capacities of up to 0.0456 mmol P/g, which were nearly
proportional to the Al loading amounts. The adsorption capacities of Al/JW02 and
Al/JW03 acquired from the adsorption isotherm were 0.0943 and 0.132 mmol P/g,
respectively, which are comparable to those of other inorganic adsorbents. The
adsorption densities (0.302 mmol P/mmol Al for Al/JW02 and 0.291 mmol P/mmol
Al for Al/JW03) suggest that the reaction between orthophosphate and Al was
inner-sphere binding. The decrease in P uptake below pH 4 observed in the
adsorption envelope was caused by the release of loaded Al from the adsorbents.

Abstract: In this study, the interaction between surfactant-containing mesoporous
silicates and Pb2+ ions in water was investigated through adsorption tests and
characterizations. The mesoporous silicates containing dodecylamine as the
surfactant showed a Pb2+ adsorption capacity of 198.6 mg g-1, a value obtained from
the fit of the adsorption isotherm to the Langmuir model. X-ray diffraction patterns
revealed that the intensity of the main peak for the mesoporous silicates decreased
after the adsorption test, implying that Pb2+ ions attached to dodecylamine. Scanning
electron microscopy images of the adsorbent before and after Pb2+ adsorption
indicated that there was no morphological change in the mesoporous silicate. When
comparing FT-IR patterns for the adsorbent before and after Pb2+ adsorption, a new
IR band was observed at 1394 cm-1 after Pb2+ adsorption, which proved that
coordination bonding occurs between Pb2+ ions and amino groups in the surfactant.

experiments showed that amount of Cu(II) ions adsorbed increases with increase of
the initial concentration and temperature. The adsorption kinetic data were
interpreted by pseudo-first-order and pseudo-second-order rate equations. The
suitability of Langmuir, Freundlich and Dubinin-Radushkevich (D-R) adsorption
models to the equilibrium data was investigated. The Langmuir isotherm was found
to provide the best theoretical correlation of the experimental equilibrium data. The
thermodynamic and kinetic activation parameters were derived to predict the nature
of adsorption process and discussed in detail. The isosteric heat of adsorption was
constant even after increase in surface loading. The removal efficiency of
HA-Am-PAA-B was tested using electroplating industry wastewater. The desorption
of adsorbed Cu(II) ions was achieved by 0.1 M HCl and four adsorption/desorption
cycles were performed without significant decrease in the adsorption capacity. (C)

Abstract: The capability for the adsorption of Cu(II)-ion with mesoporous silica
materials, such as MCM-41, SBA-15 and XPD-2412, after functionalizing with
amine groups, such as aminopropyltriethoxysilane (APTES), N(beta-aminoethyl)
gamma-aminopropylmethyl
dimethoxysilane
(AEAPMDMS)
and
N’-(3-(trimethoxysilyl)propyl) diethylenetriamine (TMSPDETA), was investigated
in this study. N2 adsorption, XRD and elemental analysis methods were performed to
gain an understanding of the structure and surface properties of the mesoporous silica
materials. Of the absorbent materials, MCM-41, functionalized with APTES, showed
the best activity for the adsorption of Cu(II)-ion. Compared with the mesoporous
silica materials functionalized with APTES, those functionalized with AEAPMDMS
and/or TMSPDETA showed lower adsorption capabilities, which may have been due
to the locations of the amine groups. Most of the amine-organic domains were
suggested should exist near the opening of channels or external surfaces.
Furthermore, the rate of adsorption of Cu(II)-ions matched well with a
pseudo-second-order kinetic model. (C) 2011 The Korean Society of Industrial and

Abstract: Olive stone (OS) and pine bark (PB) were used as effective biosorbents for the
removal of Cu(II) from aqueous solutions. The biosorbents were characterized by
elemental analysis, potentiometric titrations, surface area and pore size distribution
and FTIR analyses. Batch adsorption experiments were carried out as a function of
pH, particle size, biosorbent dosage, contact time and initial copper concentration.
Equilibrium data agreed well with Langmuir isotherm. The kinetics data fitted well
into the pseudo-second-order model with correlation coefficient greater than 0.99.
Finally, dynamic biosorption studies were carried out using a packed bed column and
the main column parameters were determined. (C) 2011 The Korean Society of

bacteria in ultra-pure water-systems-Media selection and process component
evaluations. Journal of Industrial Microbiology, 8 (4), 223-227.
Abstract: Presently, tryptic soy agar (TSA) medium is used in the semiconductor
industry to determine the concentration of viable oligotrophic bacteria in ultra-pure
water systems. Deionized water from an ultra-pure water pilot plant was evaluated
for bacterial growth at specific locations, using a non-selective medium (R2A)
designed to detect injured heterotrophic as well as oligotrophic bacteria. Results were
compared to those obtained using Tryptic Soy Agar. Statistically greater numbers of
bacteria were observed when R2A was used as the growth medium. Total viable
bacterial numbers were compared both before and after each treatment step of the
recirculating loop to determine their effectiveness in removing bacteria. The
reduction in bacterial numbers for the reverse osmosis unit, the ion exchange bed,
and the ultraviolet sterilizer were 97.4%, 31.3%, and 72.8%, respectively, using TSA
medium, and 98.4%, 78.4%, and 35.8% using R2A medium. The number of viable
bacteria increased by 60.7% based on TSA medium and 15.7% based on R2A
medium after passage of the water through an in-line 0.2-mu-m pore size nylon filter,
probably because of the growth of bacteria on the filter. Our results suggest that R2A
medium may give a better representation of the microbial water quality in ultra-pure
water systems and therefore a better idea of the effectiveness of the various treatment
processes in the control of bacteria.

Abstract: A strain of Myrothecium verrucaria that showed a high capacity for rapid
decolorization of textile dye solutions was isolated from soil. As much as 70%, 86%,
and 95% of Orange II, 10B (blue) and RS (red) dyes (color index no. 15510, 20470,
23635), respectively, were adsorbed from solutions of approximately 0.2 g dye per
liter in 5 h by approximately 4.5 g dry weight of cells per liter of dye solution. Intact
cells showed a higher adsorption capacity than disrupted cells for Orange II and RS
but not for 10B. Dye bound to cells was recoverable by extraction with methanol and
methanol-treated cells were able to be recycled, albeit with a slightly diminished
dye-binding capacity. The Tween detergents were shown to reduce dye adsorption.
Dyes strongly bound to the fungal biomass required sonication in dH2O or in Triton
X-100 or extraction with methanol for their removal, These results suggest that
hydrophobic/hydrophilic interactions are important in dye binding.

Applications in environmental biotechnology. Journal of Industrial Microbiology, 13
(2), 126-130.
Abstract: Fungi can accumulate metal and radionuclide species by physico-chemical
and biological mechanisms including extracellular binding by metabolites and
biopolymers, binding to specific polypeptides and metabolism-dependent
accumulation. Biosorptive processes appear to have the most potential for
environmental biotechnology. ‘Biosorption’ consists of accumulation by
predominantly metabolism-independent interactions, such as adsorptive or
ion-exchange processes: the biosorptive capacity of the biomass can be manipulated
by a range of physical and chemical treatments. Immobilized biomass retains
biosorptive properties and possesses a number of advantages for process applications.
Native or immobilized biomass can be used in fixed-bed, air-lift or fluidized bed
bioreactors; biosorbed metal/radionuclide species can be removed for reclamation
and the biomass regenerated by simple chemical treatments.

Abstract: A bacterium identified as Proteus mirabilis was isolated from acclimated
sludge from a dyeing wastewater treatment plant. This strain rapidly decolorized a
deep red azo dye solution (RED RBN). Features of the decolorizing process related
to biodegradation and biosorption were also studied. Although P. mirabilis displayed
good growth in shake culture, color removal was best in anoxic static cultures. For
color removal, the optimal pH and temperature were 6.5-7.5 and 30-35ºC,
respectively. The organism exhibited a remarkable color removal capability, even at
a high concentration of azo dye. More than 95% of azo dye was reduced within 20 h
at a dye concentration of 1.0 g L-1. Decolorization appears to proceed primarily by
enzymatic reduction associated with a minor portion, 13-17%, of biosorption to
inactivated microbial cells.

Full Text: J\J Ind Mic Bio24, 146.pdf
Abstract: Accumulation of heavy metals by Pseudomonas fluorescens 4F39 was rapid
and pH-dependent. The affinity series for bacterial accumulation of metal cations
decreased in the order Ni>>Hg>U>>As>Cu>Cd>Co>Cr>Pb. Metal cations were
grouped into those whose accumulation increased as the pH increased, with a
maximum accumulation at the pH before precipitation (Ni, Cu, Pb, Cd, Co), and
31
those whose maximum accumulation was not associated with precipitation (Cr, As,
U, Hg). High Ni2+ accumulation was studied. Electron microscopy indicated that at
pH 9, Ni2+ accumulated on the cell surface as needle and hexagon-like precipitates,
whose crystalline structure was confirmed by electron diffraction analysis and
corresponded to two different orientations of the nickel hydroxide crystals. Crystals
on cells showed marked anisotropy by X-ray powder diffraction, which differentiated
them from crystals observed in nickel solution at pH 10 and 11 and from commercial
nickel hydroxide. Nickel biosorption by Pseudomonas fluorescens 4F39 was a
microprecipitation consequence of an ion exchange.

studies investigated the use of rotating biological contactor (RBC) biofilms in
treatment of a wastewater containing cadmium, copper and zinc, each at a
concentration of 100 mg L-1. In particular, the influence of hydraulic retention time
(HRT) on metal accumulation was studied. Longer HRTs (>12 h) were associated
with greater metal removal than short HRTs, particularly with regard to cadmium
and zinc. The system was also shown to operate successfully over an extended period
of time, at an HRT of 24 h, with removal efficiencies of approximately 34%, 85%
and 57% for Cd2+, Cu2+ and Zn2+ respectively after 5-8 weeks contact.

Abstract: Kinetic studies with Pseudomonas aeruginosa using actinides and lanthanides
indicated a two-phase metal uptake. Equilibrium uptake data of all the metals studied
could be fitted to Langmuir as well as Freundlich models. The Scatchard plots
showed that there were mainly two types of receptor sites on the cell walls of P.
aeruginosa having different affinities for the metal ions. EDAX studies revealed
replacement of calcium and magnesium ions from biomass by sorbed metal. Around
85% of the adsorbed metal could be released using citrate buffer (pH 4.0, 0.2 M).
Metal desorption was as high as 95% with HCl. Continuous flow studies using P.
aeruginosa immobilized on activated alumina gave 80% enhancement of lanthanum
removal efficiency compared to the control column. Regeneration of the column

resulted in 80% of its initial capacity in succeeding cycles.

Full Text: J\J Ind Mic Bio29, 163.pdf
Abstract: Cladosporium strain AJR318, 501 was tested for its ability to sorb the
organochlorine pesticide (OCP) p,p’-DDT from aqueous media. When p,p’-DDT
was added to distilled water, ethanol or 1-propanol solutions in excess of its
solubility, p,p’-DDT was sorbed onto the fungal biomass. Increasing the amount of
p,p’-DDT in solution by changing the medium composition increased sorbent uptake:
p,p’-DDT uptake by the fungal biomass was 2.5 times greater in 25% 1-propanol (17
mg of p,p’-DDT g-1 dry weight fungal biomass) than in distilled water. When
p,p’-DDT was dissolved in 25% 1-propanol (12 mg l-1), rapid p,p’-DDT sorption
occurred during the first 60 min of incubation. p,p’-DDT in solution was reduced to
2.5 mg l-1 with the remaining p,p’-DDT recovered from the fungal biomass. A
number of environmental parameters were tested to determine their effect on
p,p’-DDT biosorption. As arsenic (As) is prevalent at DDT-contaminated cattle dip
sites, its effect on p,p’-DDT uptake was determined. The presence of As [As(III) or
As(V) up to 50 mg l-1] did not inhibit p,p’-DDT uptake and neither As species could
be sorbed by the fungal biomass. Changing the pH of the medium from pH 3 to 10
had a small effect on p,p’-DDT sorption at low pH indicating that an ion exchange
process is not the major mechanism for p,p’-DDT sorption. Other mechanisms such
as Van der Waals forces, chemical binding, hydrogen bonding or ligand exchange
may be involved in p,p’-DDT uptake by Cladosporium strain AJR318, 501.

Full Text: 2011\J Ind Mic Bio38, 51.pdf
Abstract: The present study reports the feasibility of using Rhodotorula glutinis biomass
as an alternative low-cost biosorbent to remove Ni(II) ions from aqueous solutions.
Acetone-pretreated R. glutinis cells showed higher Ni(II) biosorption capacity than
untreated cells at pH values ranging from 3 to 7.5, with an optimum pH of 7.5. The
effects of other relevant environmental parameters, such as initial Ni(II)
concentration, shaking contact time and temperature, on Ni(II) biosorption onto
acetone-pretreated R. glutinis were evaluated. Significant enhancement of Ni(II)
biosorption capacity was observed by increasing initial metal concentration and
temperature. Kinetic studies showed that the kinetic data were best described by a
33
pseudo-second-order kinetic model. Among the two-, three-, and four-parameter
isotherm models tested, the Fritz-Schluender model exhibited the best fit to
experimental data. Thermodynamic parameters (activation energy, and changes in
activation enthalpy, activation entropy, and free energy of activation) revealed that
the biosorption of Ni(II) ions onto acetone-pretreated R. glutinis biomass is an
endothermic and non-spontaneous process, involving chemical sorption with weak
interactions between the biosorbent and Ni(II) ions. The high sorption capacity
(44.45 mg g(-1) at 25A degrees C, and 63.53 mg g(-1) at 70A degrees C) exhibited
by acetone-pretreated R. glutinis biomass places this biosorbent among the best
adsorbents currently available for removal of Ni(II) ions from aqueous effluents.

Abstract: Wild polioviruses were isolated a number of times in The Netherlands outside
the epidemic periods (1978 and 1992-1993) from patients infected abroad, from
subclinically infected persons, and from river water. Sequence comparisons revealed
discrete sources of importation: the Mediterranean, India, and Indonesia. The
observed wide genetic variation is indicative of repeated importation and not of
indigenous circulation. Isolates identical or closely related to the epidemic type 1
strain of 1978 were found in clinical and environmental specimens until 1983,
probably due to repeated importation from Turkey. Viruses related to the 1992-1993
epidemic type 3 virus had already been isolated six times before the epidemic. of
particular importance are two documented isolations of prototype wild poliovirus
indistinguishable from that used to produce the inactivated vaccine. These data
underscore the continued risk to the unvaccinated religious population of exposure to
wild poliovirus.

Abstract: A mouse model of vancomycin-resistant Enterococcus faecium (VRE)
intestinal colonization was used to study the effect of different subcutaneous
antibiotics on persistence and density of VRE colonization. Gastric inoculation of a
clinical VanB VRE isolate, in conjunction with oral vancomycin in drinking water
(250 µg/mL), resulted in high-level VRE colonization (mean, 9.5 log(10) cfu/g) in all
169 experimental mice. After discontinuation of oral vancomycin, the level of VRE
in the stool specimens of mice receiving subcutaneous saline steadily decreased
(mean, 3.59 log(10) cfu/g at day 19). Subcutaneous vancomycin, clindamycin,
piperacillin-tazobactam, ticarcillin-clavulanic acid, metronidazole, cefotetan,
ampicillin, and ampicillin-sulbactam all promoted persistent high levels of stool VRE.
Subcutaneous ceftriaxone, cefepime, ciprofloxacin, and aztreonam promoted
increased VRE density to a lesser degree or not at all. Thus, in a mouse model,
vancomycin and antibiotics with potent antianaerobic activity promoted persistent
high-density intestinal VRE colonization, whereas antibiotics lacking potent
antianaerobic activity did not.

Abstract: Science linkage index, which is the average citation frequency of scientific
literatures in patents, has been a useful means for analyzing the relationship between
scientific research and innovation. This indicator, however, does not reflect any
information contained in the scientific literatures. In this study, we made a list of
scientific literatures cited by influential patents, and gained bibliographic information
by checking them up with science citation index (SCI). From this analysis, we found
that Japan is the third biggest producer of scientific literatures cited by influential
patents, next to the U.S. and UK. And one global trend became clear that universities
are great contributors to producing scientific knowledge as a source of patent
inventions. The contribution of Japanese governmental research institutes is smaller
than other countries. Finally, we found three problems with which Japanese life
science is faced now, 1) number of patent applications is small, 2) patent inventors
do not utilize scientific knowledge extensively, and 3) there are relatively fewer
scientific literatures as a source of world-class patent inventions.

Abstract: From the point of view of scientific productivity, as evidenced by publications
in periodicals, nations of the world can be classified into three groups, viz. advanced,
middle-level and peripheral. In their turn scientific journals are of two, kinds: (a)
national, regional or local; and (b) international. Most of the journals published in
middle-level countries are local journals. Considered here are 95 English language
journals published in Australia, Canada, India and Israel, which are indexed in
Science Citation Irtdex. A significant characteristic of local journals is their
relatively low cognitive contribution to the mainstream of international research
activity. This can be figuratively termed as an ‘island effect’. This is the case with
almost all Australian, Canadian, Israeli and Indian journals today. Most of these
journals cite more than they get cited. This negative balance of citations is another
38
characteristic of local journals. Local journals cite a much greater proportion of older
references than international journals, indicating their preoccupation with problems
of low current relevance and relative inability to attract papers in frontier problems.
In the nations considered, there appears to be very little intercitation between physics
and chemistry journals or between chemistry and life science journals indicating a
further ‘island effect’ and absence of any consequential interaction between
disciplines. In the four middle-level countries considered, Canada and Australia seem
to fare better than Israel and India. Reasons for this, at least in part, probably lie
outside the cognitive domain of science.

Abstract: Scientific research is becoming an increasingly collaborative endeavour. The
nature and magnitude of collaboration vary from one discipline to another, and
depend upon such factors as the nature of the research problem, the research
environment, and demographic factors. Earlier studies have shown a high degree of
correlation between collaboration and research productivity, and between
collaboration and financial support for research. The extent of collaboration cannot
be easily determined by traditional methods of survey and observation. Bibliometric
methods offer a convenient and non-reactive tool for studying collaboration in
research. In this paper, several types of collaboration have been identified, and earlier
research on collaboration has been reviewed. Further research is needed to refine the
methods of defining and assessing collaboration and its impact on the organization of
research and communication in science.

Abstract: Small countries practising science rarely graduate to the level of performing
quality research in sophisticated areas. Viewed on this background, an analysis of
130 papers on superconductivity published by Israeli researchers and indexed in
Physics Abstracts 1971-1982 reveal that Israel does pretty well in this area. Prolific
institutions and authors have been identified as well as journals most often used,
highly cited papers, etc. Many of the papers appeared in high impact international
journals, with Physical Review B (26), Journal of Low Temperature Physics (11) and
Solid State Communications (10) leading the field. Among the five institutions active
in the area, Tel Aviv University (68) accounts for more than half of Israel’s
publication output. Hebrew University (32) and Technion Institute of Technology
(22) are the other major centres of research in superconductivity. Five of the 130
papers have won more than 20 citations each up to 1982, and 22 papers more than 10
citations. Israeli papers in superconductivity seem to belong to the mainstream
literature in the area as seen from their decent citation record, which is better than
that of Canada and almost close to that of the USA. Most of these papers are
theoretical/computational and about 30% of them are experimental.

Abstract: A scientometric analysis of papers published over a two-year period from the
five ASEAN Countries, viz. Indonesia (182), Malaysia (452), the Philippines (241),
Singapore (258) and Thailand (447), and covered in Science Citation Index 1979 and

1979-1983 reveals that despite the relative economic affluence, science in these
countries is still on the periphery. Except in the Philippines, the thrust in these
countries seems to be in medical research as is evident from the large number of
papers published in medical journals. In the Philippines, medicine comes a close
second to agriculture, which leads, largely thanks to the contributions of the
International Rice Research Institute (IRRI). Prolific authors, and institutions and
journals often used by ASEAN scientists, and the better-cited papers are identified,
Most papers are published in low-impact journals and are rarely cited.

Abstract: Review of the scientific output of the State of Kuwait on the occasion of the
25th anniversary of its independence. Prior to 1970, only about 100 publications
were credited to Kuwaiti institutions. The majority of these papers were medical
reports published in local journals. In contrast, the 1970s and 1980s witnessed a
steady growth with an average doubling time of three years. In 1983, 185
publications were credited to Kuwaiti institutions, and 80% of these appeared in
international journals. This represents 1.1 articles per 10000 populations, a
respectable figure in comparison to Third World standards While Third World
countries put more emphasis on research in the life sciences, the distribution of
research publications of Kuwait closely match that of the World’s scientific
publications as a whole as seen from the Science Citation Index. 59% of all Kuwaiti
authored articles are in the life sciences as against 55% of the international literature.
62.6% of Kuwaiti publications appeared in journals with impact factors ranging from
0- < 1 as against 46.6% of the international literature, and 3.3% of Kuwaiti
publications appeared in journals with impact factor > 4 as against 65% of the
international literature. Furthermore, 43% of Kuwaiti publications were not cited at
all as against 25% of the international literature, and Kuwaiti publications averaged
1.8 citations per publication over a 5 year period as against a world average of 4.8
and a Latin American average of 2.9. Overall, the average citedness of papers
published from Kuwait comes close to matching that of India, but is inferior in
comparison with the standards set by the scientifically advanced countries. On the
positive side Kuwaiti science appears to be steadily improving.

Abstract: Recent reductions in research budgets have led to the need for greater
selectivity in resource allocation. Measures of past performance are still among the
most promising means of deciding between competing interests. Bibliometry, the
measurement of scientific publications and of their impact on the scientific
community, assessed by the citations they attract, provides a portfolio of indicators
that can be combined to give a useful picture of recent research activity. In this
state-of-theart review the various methodologies that have been developed are
outlined in terms of their strengths, weaknesses and particular applications. The
present limitations of science indicators in research evaluation are considered and
some future directions for developments in techniques are suggested.

Abstract: Some bibliometric characteristics of university research on European
Integration were investigated via the EURISTOTE database and its equivalent
printed sources. Of 14,065 records in the database, 67% referred to studies in
progress or completed and 33% to researchers. It is thus of the mixed bibliographic
and factual type. “Sectoral affairs of the European Communities” were the most
studied subject (35.7%) not surprisingly as they include “Agriculture” (18% of
“Sectoral affairs” and 6.5% of the total number of database entries by subject).
Germany produced the largest number of studies (24%), whilst the Communrty
countries indmdually and the European Communities as a whole were the most
42
studied countries (78.5%). The low proportion of research published as a periodical
article (20%) was characteristic of social science literature. “Other research reports”
was the dominant document form (44%) French was the most popular language of
publication (28%), whilst English was the most common working language of the
researchers (27%). Of the researchers studying European Integration prob lems. two
thirds held the academic rank of Professor or its equivalent. Economics and Law
were their most common academic disciplines (33% each). Keyboarding errors are
observable but few. Missing data, probahly due to incomplete questionnaire returns,
are quite high In some fields.

thereby enhance the organi zation of knowledge rather than documents. Recent
theoretical contributions to bibliometrics are seen, in part, as responding to this call.
We study and classify such contributions, discuss their reasonableness,
appropriateness and exactness, using the decision maker/end user-oriented focus.
Because of similari ties in the application of mathematical abstractions to econom ics
and to information science, we discuss the possible eco nomic implications of some
recent contributions and the con straints on their application, and offer suggestions
for their application particularly in the Third World where “it is cer tainly the case
that information science has hardly ever been recognized”.

Abstract: A new approach to scientometric indicators which is based on frequency
distribution characteristics is presented. The publication productivity of ten major
OECD countries during the 1981-1985 period is studied. A stochastic “cumulative
advantage” process having a Waring-type stationary limit distribution is assumed to
underlie the publication process. This model makes it possible to estimate such
indicators as the “Publication Potential” and the “Cumulative Advantage Coefficient”
which indicate the number of potential and of factual authors and the effect of the
43
“success-breeds-success” phenomenon, respectively. A discussion of the publication
behaviour of the scientific elite based on indicators of the distribution tail concludes
the comparative evaluation.

Abstract: Publication-based indicators of agricultural research activ ity were developed
to assist in the evaluation of the knowledge transfer component of an agricultural
research network involv ing the six Southern Cone countries of South America
(Argentina, Bolivia, Brazil, Chile, Paraguay and Uruguay). The generation of
agricultural knowledge in these countries, as reflected by the CAB Abstracts
database, has grown by about 50% over the period 1973 to 1982. The academic
sector accounts for a substantial amount of this activity, about 40%. There is
however significant cross-country variation in these figures. The transfer of
agricultural knowledge among agncultural researchers in the region, and between
these researchers and the world’s research community, was studied using the SCI
SEARCH database. The region generally relies heavily on international sources of
knowledge; domestic sources are also important, especially in the larger systems,
while regional sources are of only minor importance. There is some evidence,
however, that in recent years regional sources may have be come relatively more
important for the smaller research sys tems. There is also a suggestion that the
region’s researchers, particularly those in the smaller systems, are drawing on an
ageing knowledge base.

Abstract: A new bibliometric indicator, the hierarchically-adjusted author
proportiometric index, is described. It is a much improved indicator of individual
scientific output, over that provided by publication number. This index is obtained by
multiplying the number of pages in any publication of original research by a real, or
suitably derived, weighting factor that acknowledges each author’s proportional or
absolute contribution to the work. This method, its logic and its analytical advantage
are illustrated by a suitable hypothetical example, and by comparative bibliometric
analyses of real data: the method dramatically improves individual assessments
relative to publication counts in some cases, and vice versa in others. Future uses
for.the method may include research budgetary analysis, research audit and the
monitoring of personal research performance. The method may complement, but is
clearly separate from, citation bibliometry.

Abstract: The quality of subject indexing by Chemical Abstracts Indexing Service is
45
studied by confronting authors with the particular indexing terms attributed to their
papers. Data were drawn from the online CA-file, available from STN host-computer,
for 270 articles published in 54 journals, five articles out of each journal. Responses
(80%) indicate the superior quality of keywords, both as content descriptors and as
retrieval tools. Author judgements on these two different aspects do not always
converge, however. CAS’S indexing policy to cover only “new” aspects is reflected
in authors’ judgements that index lists are somewhat incomplete, in particular in the
case of thesaurus terms (index headings). The large effort expended by CAS in
maintaining and using a subject thesaurus, in order to select valid index headings, as
compared to quick and cheap keyword postings, does not lead to clear superior
quality of thesaurus terms for document description nor in retrieval. Some 20% of
papers were not placed in the “proper” CA main-section, according to authors. As
concerns the use of indexing data by third parties, e.g. in bibliometrics, users should
be aware of the indexing policies behind the data, in order to prevent invalid
interpretations.

different disciplines by using a purposive sampling technique. Various Spearman’s
Correlation Coefficient tests were computed to find out if a subject relationship
existed between the Articles which have the same keywords in their titles (Parent
Articles and Related Records). Th-ugh the analysis the hypothesis has been verified
showing that there is a relationship between the articles which are citing the same
references. This was determined by co-occurrences of the same keywords among the
shared references. However, there are some unique differences in the science and the
social science disciplines that exist in these two databases.

analysis has been employed. The paper also examines the idea of the development of

commercially viable. The paper describes a citation study of Eugene Garfield, and
concludes that he may be the most heavily cited information scientist, that he is a
heavy self-citer, and that the reasons why other authors cite Garfield are different
from the reasons why he cites himself. The paper concludes that citation studies
remain a valid method of analysis of individuals’, institutions’, or journals’ impact,
but need to be used with caution and in conjunction with other measures.

Abstract: In an exploratory study, the time behaviour of citations to articles of seven
journals representing different scientific fields (sociology, psychology, chemistry,
general and internal medicine, statistics and probability theory) were analysed to
establish: (i) differences in ageing and reception speed between social sciences and
other science fields, to determine (II) if there are connections between ageing and
reception, and (iii) if deviations are due to fields or individual journals. Bibliometric
methods and citation-based indicators were used within a stochastic model. It was
found that obsolescence of the social science journals in the set is slower than for the
medical and chemistry journals, The behaviour of the mathematical journal is similar
to the ones in social sciences. The study suggests that ageing seems to be specific to
the field rather than to the individual journal. On the other hand, slow ageing does
not necessarily correspond with slow response. Impact factors based on the usual two
47
years’ observation period may therefore be distorted by deviating ageing behaviour.

literature of information science and other disciplines in order to: determine what
proportion is devoted to citation analysis, develop an inductive typology to
categorize the major foci of research being conducted under the rubric of citation
analysis, and use the typology to determine how citation analysis is applied within
information science and other disciplines. By isolating citation from bibliometrics in
general, and by exploring the topic across literatures, the authors differentiate their
work from previous studies, Analysis of data from a ten-year sample of
transdisciplinary social sciences literature suggests that two application areas
predominate: the validity of citation as an evaluation tool, and impact or performance
studies of authors, journals and institutions.

Abstract: It has been claimed that the ‘information society’ constitutes a new paradigm.
48
The paper describes the use of online bibliometrics to investigate this claim. The
methodology involved systematic searching of the databases Information Science
Abstracts, Social SciSearch, INSPEC and Arts & Humanities Search. Results showed
the remarkable extent and range of journal citations over a ten-year period, at least in
the information, social and engineering sciences. The wide range of disciplinary,
organisational and national affiliations is commented upon. Title and sample
contextual analysis of papers suggests that a majority of researchers regard the
concept of the ‘information society’ as a paradigm, more or less assuming the
validity of the dogmas of ‘information society’ theorists such as Daniel Bell.
However, the searches also revealed an apparent decline in frequency of use of the
term. Judged by its bibliometric behaviour, it is not yet possible to say with any
certainty that the ‘information society’ has achieved paradigmatic status. Some
suggestions for further research are included

Full Text: 1996\J Inf Sci22, 125.pdf
Abstract: One can suppose that Bradford’s law is valid for all scientific fields. As an
implication of this general validity and because of limitations of space, journals must
differ in their subject structure, and every journal must have its own hierarchy of
subjects, conforming to a Bradford or a similar distribution. The phenomenon of
subject hierarchies is shown here for ten journals in twentieth-century psychology
and mathematical logic and for five journals in nineteenth-century mathematics,
taking instead of Bradford’s original rank-size distribution the equivalent, but more
general, Pareto distribution. It is hypothesised then that hierarchies of subjects within
journals correspond to the reception process, i.e. to the structure of interests of their
readers. This is illustrated by means of an example of 30 most prolific
nineteenth-century mathematicians. It is argued that the phenomenon of subject
hierarchies in journals and in readers has to be considered in a causal explanation of
Bradford’s law.

Abstract: Based on the particular case of the average impact factor of a subfield versus
the impact factor of this subfield as a whole, the difference is studied between an
average of quotients, denoted as AQ, and a global average, obtained as a quotient of
averages, and denoted as GQ. In the case of impact factors, AQ becomes the average
impact factor of a field, and GQ becomes its global impact factor. Many applications
49
in the context of informetrics and scientometrics are given, e.g. the Price index, the
text to reference ratio, ageing, the receptivity factor for foreign literature, journal
price calculation, discipline influence scores, and fill-rates as measures of library
performance, We strongly claim that, in most applications, the global average is the
preferred one. It is also shown that, if geometric averages are used instead of
arithmetic ones in the definition of AQ and GQ, the difference between the two
approaches is eliminated.

Abstract: This paper describes results of a comparative analysis between Social
Sciences Citation Index (SCCI) and a locally created Polish Sociology Citation Index.
It concludes that, while SSCI is a valuable tool in assessing the presence and impact
of Polish sociology in an international context, a deeper view of the discipline and its
development may be obtained through the analysis of a locally oriented index.

Abstract: The paper examines patterns of self-citation in six disciplines distributed
equally among the physical and social sciences and the humanities. Sample articles
were examined to determine the relative numbers and ages of self-citations and
citations to others in the bibliographies and to the exposure given to each type of
citation in the text of the articles. Significant differences in the number and age of
50
citations between disciplines were found. Over all, 9% of all citations were
self-citations; 15% of physical science citations were self-citations, as opposed to 6%
in the social sciences and 3% in the humanities. Within disciplines, there was no
significantly different amount of coverage between self-citations and citations to
others. Over all, it appears that a lack of substantive differences in self-citation
behavior is consistent across disciplines. The number of words devoted to
self-citations vary among disciplines, but remain constant within a discipline for both
self-citations and citations to others.

Full Text: J\J Inf Sci25, 67.pdf
Abstract: Author co-citation analysis (ACA) has been used to explore changes in the
intellectual base of the information retrieval (LR) held over two consecutive time
periods: 1987-1991 and 1992-1997. Thirty-nine highly cited IR researchers were
selected as the research sample. Multidimensional scaling (MDS) and clustering
techniques (CT) were used to create the two-dimensional maps to display the
dynamic intellectual structure of IR, based on scholars citing their work over these
two time periods. Factor analysis (FA) has been used to reveal the ‘breadth’ of the
authors’ research areas. ACA offers a good technique that contributes to the
understanding of intellectual structure in the sciences and possibly in other areas to
the extent that those areas rely on formal scholarly communication such as serial
publications. Nonetheless, obvious drawbacks exist in ACA. These include the
subjective nature of the interpretation of results, the difficulty of readily identifying
clusters and the inability to distinguish collaborative research relationships between
authors, Thus, ACA by itself is insufficient. However, ACA can be enhanced
significantly when combined with FA to give a more accurate acid useful picture of
the MDS results.

Citation analysis is a bibliometric measure increasingly applied to evaluate the
publication quality of individual scientists or research groups. Therefore, it is very
important to know, and to use correctly, the search methods made available to
retrieve the number of citations.
Different search methods and their specific features and limits are discussed, and
practical problems in working with the online citation indices are described,
highlighting the pivotal role of information specialists to make accessible, and to
better use, the database data and the retrieval techniques, thus providing vital
information to institutions and research activity.

Abstract: Research performance in Korea has increased considerably in the past few
years, both with regard to relative output of publications and the number of
internationally co-authored papers. The purpose of this study is to characterise
international scientific cooperation in Korea through the numbers of internationally
co-authored papers covered by the Science Citation Index CD-ROM, 1994-1996. A
total of 3,627 collaborative papers published in 1,083 scientific journals were
selected to analyse papers written in collaboration between Korea and other countries.
The data reveal that Korea’s coauthorship level with other countries was relatively
high, representing 26.8% of national output. Among the collaborative papers, a large
majority of the papers (84%) were authored by researchers at universities, while
about 10% came from scientists at government-supported institutes and only 6%
from industry. The country with the highest rate of cooperation with Korea is the
USA (42%), followed by Japan, Italy, Germany, the UK and France. Considering the
strong interaction between Korean and American science, economic and political
factors appear to play a strong role in the international co-authorship process. The
results show clear variation in levels of international cooperation according to the
disciplines: technology, agriculture and earth sciences represent local interests, while
physics, chemistry and biology are mainstream subjects.

Abstract: The results of an experiment are described in which manuscripts submitted to

a medical journal were each sent to two reviewers, One was blinded to the details of
authorship, addresses and funding acknowledgements; the other was not. The
intention was to see whether papers with larger numbers of these parameters would
be more favourably reviewed, either because the reviewers were directly influenced
by these factors or because the papers were really of higher quality. it turned out that
the differences between the reviewers’ marks for each paper were not correlated with
the parameters, but that the sums of the two were so correlated. This suggests that the
tendency of papers with more authors, etc, to be published in higher-impact journals
is actually due to their perceived quality and not to the numbers of authors per se.

Abstract: From an analysis of papers indexed in three years of Biochemistry and
Biophysics Citation Index (1992, 1995 and 1998), it is found that 103 institutions in
Israel have published 4,112 papers in more than 990 journals and 64 non- journal
sources published from 27 countries. More than 16% of papers have appeared in
journals with an impact factor (IF) higher than 7.00 and an equal fraction of papers
have appeared in journals with an LF of less than 1.00. The sum of the Ifs of the
journals in which papers have been published has been used as a rough measure to
quantify each institution’s research contribution. Hebrew University, the Weizmann
Institute and Tel Aviv University are the institutions publishing the largest number of
papers, while Rehovot and Jerusalem are the leading cities. Journal of Biological
Chemistry, Proceedings of the National Academy of Sciences - USA, FEES Letters
and Biochemistry are the journals most often used by Israeli researchers to publish
their work. To overcome the problems of conducting world-class research in a small
country, Israel uses collaboration. with overseas laboratories to great advantage.
More than 42% of papers in the sample involve international collaboration; half of
them with laboratories in the USA and some with Germany, France, the UK and
Canada. Over 10% of papers have resulted from domestic collaboration. In general,
internationally collaborated papers are published in higher- impact journals, but
domestically collaborated papers more often appear in lower-impact journals than
single-institution papers, While the USA remains the most important partner of Israel,
papers co-authored with French and UK collaborators raise the IF value of Israeli
contributions more than those with other partner countries

Abstract: This study examined research performance of chemists at Seoul National
University (SNU), the most prestigious university in Korea, using the numbers of
articles appearing in journals and the numbers of citations received by those articles
covered by Science Citation Index (SCI) CD-ROM, 1992-1998. A total of 651
papers published by the 29 faculty members of the Chemistry Department at SNU
and indexed by SCI during the seven-year period were considered. US and Korean
journals published in English were utilised predominantly, followed by UK journals.
Major journals used by Korean chemists are Bulletin of the Korean Chemical Society
(Korea), Tetrahedron Letters (UK), Journal of Physical Chemistry A (USA), Journal
of Chemical Physics (USA) and Journal of the American Chemical Society (USA).
In addition, half the Korean papers were published in journals having an impact
factor of one or more. Among the 651 publications, 388 were cited 2,376 times.
Considering the number of citations received by Korean papers, in terms of journal
country, papers published in US, UK and Dutch journals have a higher visibility than
others. No correlation between the number of papers by a particular chemist and the
average number of citations per paper for that chemist was indicated by the study.

Abstract: This paper poses more problems than it solves: it investigates the new (virtual)
world of the Internet and the challenges that it offers for informetric analysis. The
paper studies five different aspects. First of all, there is the increasing problem of
54
data gathering in the Internet. The second topic is the Internet version of the
informetric laws: are the same types of classical distributions valid or not? The third
topic deals with scientometric aspects: can the clickable buttons (hyper-links) in Web
pages replace the role of classical references in scientific papers? It also contains a
study of the Web impact factor and a discussion on ageing. The fourth topic
discusses information retrieval (IR) aspects of search engines. It studies aspects of
probabilistic IR as applied in these engines and poses the question of quantitative
evaluation of IR (Web analogues of recall and precision). Lastly, aspects of
complexity are discussed. The fractal nature of the Internet is highlighted and a
modest attempt to measure it is given.

Abstract: This research aims to incorporate the results of co-word analysis into

domain of information retrieval. Relevant data were first collected from Science
Citation Index and Social Sciences Citation Index for the period 1987-1997. The
results of co-word analysis on the data were compared with similar data obtained
from three thesauri: Library and Information Science Abstracts thesaurus, Library of
Congress Subject Headings and Thesaurus of Information Technology Terms. The
differences detected between them indicate that the search variety may be increased
by combining co-word analysis with the use of traditional thesauri. Subsequently, the
results of co-word analysis were compared with each other for two different periods
(1987-1991 and 1992-1997). The changes among them were identified, implying that
co-word analysis may be used directly to identify dynamic changes in its chosen
domain area, thereby providing better up-to-date information to aid the information
search process.

Abstract: The Research Assessment Exercises (RAE) conducted in the UK have
attracted various types of published response. These include citation analyses and a
review of the public reception of the RAE 1996, which included a brief critique of
the citation studies. This paper develops the critique. Largely unexplored issues in
55
the theory or assumptions of bibliometrics, e.g. the level of citation which
corresponds to a quantum of research quality, are found to emerge in the studies. A
weak, and unsatisfactorily treated, correlation between citation aggregates and
research quality for individual entities is revealed. The proposal to replace informed
peer review by citation analysis is regarded as highly unrealistic. Productive uses for
citation analysis in research evaluation are suggested. A historically rare instance of
correlation between rankings derived from citation aggregates and fi om real world
peer review has been revealed by the studies. The future value of citation analysis
could be to inform, but not to determine, judgements of research quality. A
combination of methods is advocated for future studies of the RAEs. Information
science must attend to considerations of value, as well as using established
techniques, if it is to avoid marginalisation.

Abstract: The idea of a unified citation index to the literature of science was first
outlined by Eugene Garfield [I] in 1955 in the journal Science. Science Citation
Index has since established itself as the gold standard for scientific information
retrieval. It has also become the database of choice for citation analysts and
evaluative bibliometricians worldwide. As scientific publication moves to the web,
and novel approaches to scholarly communication and peer review establish
themselves, new methods of citation and link analysis will emerge to capture often
liminal expressions of peer esteem, influence and approbation. The web thus affords
bibliometricians rich opportunities to apply and adapt their techniques to new
contexts and content: the age of ‘bibliometric spectroscopy’ [2] is dawning

Abstract: The study of the statistical regularities observed in the held of information
production and use has confirmed the existence of important similarities. Thus, the
existence of regularities and measurable ratios allow the prevision and the concept of
laws. In the 1950s, Shannon and Weaver [13] modelled the information circulation
theory. The entropy hypothesis of this theory is that the more ranked a system is, the
less information it produces. Theoretical studies have tried to formalise the
connection between the bibliometric distribution and the entropy. In this paper, we
56
try to extend previous results linked with ‘the least effort principle’ and the analytical
slope of a bibliometric distribution. In the first and second parts, we recall some
statements about entropy and bibliometric distributions and, after that, we describe
different links between them.

Abstract: Ontology is an important emerging discipline that has the huge potential to
improve information organization, management and understanding. It has a crucial
role to play in enabling content-based access, interoperability, communications, and
providing qualitatively new levels of services on the next wave of web
transformation in the form of the Semantic Web. The issues pertaining to ontology
generation, mapping and maintenance are critical key areas that need to be
understood and addressed. This survey is presented in two parts. The first part
reviews the state-of-the-art techniques and work done on semi-automatic and
automatic ontology generation, as well as the problems facing such research. The
second complementary survey is dedicated to ontology mapping and ontology
‘evolving’. Through this survey, we have identified that shallow information
extraction and natural language processing techniques are deployed to extract
concepts or classes from free-text or semi-structured data. However, relation
extraction is a very complex and difficult issue to resolve and it has turned out to be
the main impediment to ontology learning and applicability. Further research is
58
encouraged to find appropriate and efficient ways to detect or identify relations
through semi-automatic and automatic means.

Full Text: J\J Inf Sci28, 375.pdf
Abstract: This is the second of a two-part paper to review ontology research and
development, in particular, ontology mapping and evolving. Ontology is defined as a
formal explicit specification of a shared conceptualization. Ontology itself is not a
static model so that it must have the potential to capture changes of meanings and
relations. As such, mapping and evolving ontologies is part of an essential task of
ontology learning and development. Ontology mapping is concerned with reusing
existing ontologies, expanding and combining them by some means and enabling a
larger pool of information and knowledge in different domains to be integrated to
support new communication and use. Ontology evolving, likewise, is concerned with
maintaining existing ontologies and extending them as appropriate when new
information or knowledge is acquired. It is apparent from the reviews that current
research into semi-automatic or automatic ontology research in all the three aspects
of generation, mapping and evolving have so far achieved limited success. Expert
human input is essential in almost all cases. Achievements have been made largely in
the form of tools and aids to assist the human expert. Many research challenges
remain in this field and many of such challenges need to be overcome if the next
generation of the Semantic Web is to be realized.

Abstract: This study presents the results of an extensive search for links to the home

engine Google concealed between 48 and 70% of the links to the page each time it
was queried, and HotBot concealed between 20 and 39% of the link pages indexed
by it. The queries were repeated four times during a one-year period, between
January 2001 and January 2002 in order to rule out the possibility of an accidental
finding. The other search engines examined also concealed some pages but to a much
smaller extent. The findings raise questions about the use of WIF (the Web Impact
Factor) as a scientometric indicator based on data retrieved from commercial search
engines. The content of the retrieved and concealed pages was characterized using
the method of content analysis. The characterization shows that the set of initially

retrieved pages, and the set of initially retrieved pages plus the set of concealed pages,
are significantly different for Google.

Abstract: This paper introduces two new web link count metrics to complement the
existing Web Impact Factor. The first is provisionally cast as an indicator of the
average degree of online informal scholarly communication and information use by
the academics in a given university. The second has a similar construction but
focuses on the degree of web interconnection in terms of both inlinks and outlinks.
The latter metric is based upon a more elaborate mechanism than raw link counts:
totalling the minimum number of links between universities over all distinct pairs in
the chosen set that include the given institution. Statistical tests give evidence that
the results of both correlate with institutional research productivity in the UK,
providing preliminary support for their continued development. Further research is
needed into causes of linking in order to allow more meaningful interpretations of
their values to be made.

Abstract: This paper presents an analysis of a journal in the field of library and

selected is Journal of Information Science (JIS). The methods are mainly publication
and citation analyses, including a journal co-citation analysis, self-citation analyses,
an overlap analysis, as well as Lotka’s law regarding authorship characteristics. This
variety of methods provides a multifaceted image. The analyses are focused on the
last 25 years, since the basis of research primarily is ISI’s citation databases and
LISA, in which JIS has been indexed since 1979. The library and information science
journal is pictured by a catalogue of different methodologies as a supplement to
Journal Impact Factor (JIF), the usual tool of journal evaluation in measuring the
impact of a journal. The areas of study are the visibility of the journal in databases,
the pattern of authorship, the pattern of self-citations, internalization and scientific
impact. The methods employed in analysing JIS supplement and sustain other
analyses in the field of library and information science journals.

Abstract: The need to understand authors’ motivations for creating links between

links from the ac.uk domain. A classification-scheme was created and applied to this
collection. Obtaining inter-classifier agreement as to the single main link creation
cause was very difficult because of multiple potential. motivations and the fluidity of
genre on the Web. Nevertheless, it was clear that, whilst the vast majority, over 90%,
was created for broadly scholarly reasons, only two Were equivalent to journal
citations. It is concluded that academic web link metrics will be dominated by a
range of informal types of scholarly communication. Since formal communication
can be extensively studied through citation analysis, this provides an exciting new
window through which to investigate a facet of a previously obscured type of
communication activity.

Abstract: This study developed a specialized directory system using an automatic
classification technique. Economics was selected as the subject field for the
classification experiments with Web documents. The classification scheme of the
directory follows the DDC, and subject terms representing each class number or
subject category were selected from the DDC table to construct a representative term
dictionary. In collecting and classifying the Web documents, various strategies were
tested in order to find the optimal thresholds. In the classification experiments, Web
documents in economics were classified into a total of 757 hierarchical subject
categories built from the DDC scheme. The first and second experiments using the
representative term dictionary resulted in relatively high precision ratios of 77 and
60%, respectively. The third experiment employing a machine learning-based
k-nearest neighbours (kNN) classifier in a closed experimental setting achieved a
precision ratio of 96%. This implies that it is possible to enhance the classification
performance by applying a hybrid method combining a dictionary-based technique
and a kNN classifier.

Department of Organization and Management. Through bibliometric analysis a list of
‘candidate journals’ was compiled for the institution(s) and matched with the
available portal resources. The methodology was used to see how well the portals are
supporting the current, local research activities at the institution(s), and if the new,
emerging research areas are covered by the resources pooled at the subject portals.
The article provides a set of examples which illustrate the type of information and
visualization material which could be used to explore the resources of the portals
(and the library), and to facilitate the individual searching and navigation among
students and researchers in the electronic information landscape.

Abstract: On the Web, hyperlinks have been used both to assess the impact of academic
Web sites and to trace aspects of online informal scholarly communication. They are
also used in Web information retrieval algorithms to identify important pages and to
cluster pages by topic, both of which help in ranking search engine results. In this
paper we investigate a type of link that is of particular interest for all of these
applications: one that crosses subject boundaries. We took a sample of 586 linked
pairs of domains in different UK academic sites, and extracted those that represented
different subjects, resulting in 52 pairs of domains with different subjects. These
were then grouped by the type of relationship between the source and target page.
Over a third of the links formed a scholarly connection between similar subjects, but
in 8% of cases dissimilar subjects also had a scholarly connection. Additionally,
62
higher education teaching links were seen to form an extensive cross-disciplinary
network, accounting for 19% of the links. A significant number of links (12%) also
targeted non-subject-specific general resources. The results suggest that mapping
disciplinary collaboration on the Web should be feasible but that this process and
topic identification in academic Webs would both be helped by the prior removal of
key higher education teaching and popular general pages from the data set. These,
and computing pages to a lesser extent, play a role more pernicious than ‘stop words’
in traditional information retrieval. The conclusions are of a qualitative rather than
quantitative nature because of the small effective sample size, so an initial set of
thousands of links would be required to remedy this.

of Impact Factors when publication is by paper and through parallel publishing.

Full Text: J\J Inf Sci29, 527.pdf
Abstract: This paper reports the results of a bibliometric analysis of scholarly journals in
the field of psychology. The Impact Factors of a sample of journals have been
collected from Journal Citation Reports (JCR) provided by ISI. Changes in the
Impact Factors were monitored annually over two periods, 1994-1995 and
2000-2001, the years before and after electronic journals appeared. The collected
Impact Factors of scholarly journals from these two periods are compared in the
available media. As a result, it is found that Impact Factors of 2000 and 2001 were
significantly higher than those of 1994 and 1995 in the journals published by parallel
publishing (combination journals - simultaneous publication of paper and electronic
journals). In particular, the Impact Factors of the combination journals increased
after the journals transformed their available media from paper journals to
combination ones. By contrast, in the case of paper journals, there was no significant
difference between the Impact Factors of 1994 and 1995 and those of 2000 and 2001.
Additionally, it is possible to infer from later analyses that the citation rate is not
changed by the available media in the authoritative journals which have
comparatively high Impact Factors. In journals with low Impact Factors, on the other
hand, the available media influences the citation rate.

Abstract: To better understand the topic of this colloquium, we have created a series of
databases related to knowledge domains (dynamic systems [small world/Milgram],
information visualization [Tufte], co-citation [Small], bibliographic coupling
[Kessler], and scientometrics [Scientometrics]). I have used a software package
called HistCite(TM) which generates chronological maps of subject (topical)
collections resulting from searches of the ISI Web of Science(R) or ISI citation
indexes (SCI, SSCI, and/or AHCI) on CD-ROM. When a marked list is created on
WoS, an export file is created which contains all cited references for each source
document captured. These bibliographic collections, saved as ASCII files, are
processed by HistCite in order to generate chronological and other tables as well as
historiographs which highlight the most-cited works in and outside the collection.
HistCite also includes a module for detecting and editing errors or variations in cited
references as well as a vocabulary analyzer which generates both ranked word lists
and word pairs used in the collection. Ideally the system will be used to help the
searcher quickly identify the most significant work on a topic and trace its
year-by-year historical development. In addition to the collections mentioned above,
historiographs based on collections of papers that cite the Watson-Crick 1953 classic
paper identifying the helical structure of DNA were created. Both year-by-year as
well as month-by-month displays of papers from 1953 to 1958 were necessary to
highlight the publication activity of those years.

librarianship research. Journal of Information Science, 30 (3), 227-239.
Full Text: J\J Inf Sci29, 227.pdf
Abstract: Objective. To conduct a content analysis of library and information studies
(LIS) literature published in 2001 and test the domains developed by Crumley and
Koufogiannakis.
Methods: A comprehensive list of refereed library and information studies journals was
compiled and reviewed independently by two researchers to derive a list of included
journals. Articles published in 2001 from included journals were independently
assessed for relevancy by two researchers. Researchers separately extracted and
checked data from included articles.
Results: 217 LIS journals were reviewed and 107 were included; 91 journals provided
data. 2664 journal articles were examined, with 807 (30.3%) classified as research.
The Top 10 journals for research published in 2001 were: 1) JASIST, 2)
Scientometrics, 3) Info Proc Man; 4) Coll & Res Lib, 5) Tie: I Lib Adm/Bull Med
64
Lib Assn, 7) Libs & Culture, 8) J Doc, 9) Tie: J Info Sci/J Acad Libr. For the period
studied, descriptive research (329 out of 807 articles) was published far more
frequently than any other type. The domain Information Access & Retrieval had the
highest number of research articles (314/807), followed by Collections (193/807),
Management (135/807), Education (95/807) and Reference (77/807). Two new
possible domains were identified: Library History and Professional Issues.
Conclusions: Because 36 articles fell into the domain of Professional Issues, a case can
be made to add this domain to Crumley and Koufogiannakis’ taxonomy. Library
History was not added as a domain because historical research is not used for
evidence-based decision-making. There was no evidence to support keeping the
Marketing & Promotion domain. LISA provides the best coverage of the top 10 LIS
research journals identified in this study.

Abstract: Hyperlinks between academic web sites, like citations, can potentially be used
to map disciplinary structures and identify evidence of connections between
disciplines. In this paper we classified a sample of links originating in three different
disciplines: maths, physics and sociology. Links within a discipline were found to be
different in character to links between pages in different disciplines. There were also
disciplinary differences in both types of link. As a consequence, we argue that
interpretations of web science maps covering multiple disciplines will need to be
sensitive to the contexts of the links mapped.

Abstract: One method for assessing quality of research outputs across different technical
disciplines is comparing citations received by the research output documents.
However, cross-discipline citation comparison studies require discipline
normalization, in order to eliminate discipline differences in cultural citation
65
practices and discipline differences in the number of active researchers available to
cite. The ‘definition’ of, and number of documents used to represent, a discipline
become critical. This study attempted to determine whether the citation
characteristics (average, median) of a discipline’s domain stabilized as the domain’s
size was decreased. A sample of papers (classified as research articles only, not
review articles, by the Institute for Scientific Information) published in the journal
Oncogene in 1999 was clustered hierarchically, and the citation averages and
medians were computed for each cluster at different cluster hierarchical levels. The
citation characteristics became increasingly stratified as the clusters were reduced in
size, raising serious questions about the credibility of a selected denominator for
normalization studies. An interesting side result occurred when all the retrieved
articles were sorted by number of citations. Thirteen of the fifty most highly cited
research articles had 100 or more references, whereas zero of the fifty least cited
research articles had 100 or more references.

Abstract: This Brief Communication examines the extent of publications written by a
single author in different disciplines in Israeli universities. In the natural sciences the
share of single-authored articles in the total amount of publications varies slightly
between the different fields of science. A significant difference was found while
comparing natural sciences as a whole with mathematics and a major one when
compared with the social sciences and humanities. The conclusion is that the more
theoretical is the research and the greater the share of the initial idea in the finished
article, the higher the probability that a single person will publish it.

Abstract: The presence of scholarly journals in international data bases promotes the
dissemination of research results and also facilitates requests for specific articles or
journals by end users. As scientists seek optimal visibility for their work and wish
their results to be published in journals with high circulation, it is important to know
which are the leading journals within each scientific area. This paper contains a

Humanities that are currently published in Spain, together with information
concerning their production and circulation in the different national and international

Abstract: The visualization of scientific field structures is a classic of scientometric
studies. This paper presents a domain analysis of the library and information science
discipline based on author co-citation analysis (ACA) and journal cocitation analysis
(JCA). The techniques used for map construction are the self-organizing map (SOM)
neural algorithm, Ward’s clustering method and multidimensional scaling (MDS).
The results of this study are compared with similar research developed by Howard
White and Katherine McCain [1]. The methodologies used allow us to confirm that
the subject domains identified in this paper are, as well, present in our study for the
corresponding period. The appearance of studies pertaining to library science reveals
the relationship of this realm with information science. Especially significant is the
presence of the management on the journal maps. From a methodological standpoint,
meanwhile, we would agree with those authors who consider MDS, the SOM and
clustering as complementary methods that provide representations of the same reality
from different analytical points of view. Even so, the MDS representation is the one
offering greater possibilities for the structural representation of the clusters in a set of
variables.

Abstract: Based on the second order plus time delay transfer function model of the
journal publication delay process, we establish a mathematical model of information
loss caused by publication delays. Then we collect elementary data on publication
67
delays from over 3000 articles in 18 Chinese journals in four subjects and
respectively assess information loss caused by publication delays using the model;
thus the validity of the model is demonstrated. The information loss caused by
publication delays in Chinese science journals is serious, especially in mathematics.
Final statistical and analytical results indicate that delays in publication of some
Western journals are also noticeable.

Abstract: This paper deals with a bibliometric analysis of data from the document
delivery service Subito. After a short introduction, Subito will be presented briefly.
The main part reports on the design and the results of the study, which covers the
following major topics: distribution of article orders to journals, identification of the
core journals which contribute to most article supplies, subject distribution of the
most requested journals, relation between the most requested (Subito) and the most
cited journals (SCI), differences in age of ordered and cited articles, and dependency
of journal requests on their subscription rates. As will be shown, most Subito article
orders are covered by a relatively small number of journals, most of which are from
life sciences, especially medicine. There is only a slight overlap between the most
requested and the most cited journals suggesting that these two indicators represent
different concepts. This is also confirmed by different obsolescence characteristics.
The share of current publications is much higher among ordered than among cited
articles. Finally, there was no evidence that articles of journals with higher
subscription rates are ordered more often.

Abstract: Citation context analysis is used to demonstrate the diversity of concept

of these concepts over time and across scholarly disciplines. A content analysis of
574 citation contexts from 497 journal articles citing an edition of Frederick P.
68
Brooks, Jr’s The Mythical Man-Month (MMM) over the period 1975-1999 showed
that MMM represents a variety of different concepts and is cited in a wide range of
subject areas. Over time, a high level of interest in MMM spread from software
engineering and computer science to management and information systems, with
different areas showing different patterns of focus on concepts within the work.
‘Brooks’ Law’ (the ‘mythical man-month’ or ‘adding more people to a late project
makes it later’), accounted for less than 30% of the classified citation contexts. The
findings contribute to our understanding of the diffusion of ideas in scholarly
communication, and the diversity that can underlie the creation of a reference in a
scholarly publication.

Abstract: This work is a longitudinal study of the evolution and the state of 738 web
sites at two different points in time (1997 and 2004). It tries to establish the rate of
growth and decay of the web and all the web elements. To this end, the structure and
the contents of these web sites are extracted through a crawler and compared at the
two different moments in time. The main results confirm a growth of web content

The results suggest that in the seven-year period covered by this study the web is
characterized by both strong dynamism and instability.

Abstract: The effectiveness of the analytical tools used for the evaluation of scientific
activity has been enhanced by the availability of bibliographic databases, in
particular the standard-setting Institute for Scientific Information databases, whose
operating rules are widely accepted by the scientific community. One of these rules
69
is the availability in a single field of the institutional affiliations of all the authors of
a paper. In practice this rule has been replaced by another, resulting from the
inclusion of a new option, whereby records can be retrieved by the author’s reprint
address (Reprint Address field). The outcome is diversity in the information on
affiliation that may generate some degree of uncertainty in connection with
institutional attribution when discrepancies arise between the information contained
in the two fields, mainly when the only option available is the reprint address. The
present study found a high degree of uncertainty, however, essentially for the period
prior to Web of Science, in particular for scientific evaluation in peripheral countries
such as Spain.

Full Text: 2006\J Inf Sci32, 581.pdf
Abstract: We have developed simple algorithms that allow adjacency and proximity
searching in Google and the Science Citation Index (SCI). The SCI algorithm
exploits the fact that SCI stopwords in a search phrase function as a placeholder.
Such a phrase serves effectively as a fixed adjacency condition determined by the
number n of adjacent stopwords (i.e. retrieve all records where word A and word B
are separated by n words in at least one location). The algorithm integrates over
search phrases with different numbers of adjacent stopwords to provide a flexible
70
adjacency or proximity capability (i.e. retrieve all records where word A and word B
are separated by n or fewer words in at least one location, where n is the maximum
separation desired between A and B in at least one location). The Google algorithm
exploits the fact that asterisks (in Google) separating words in a phrase function like
word wildcards. The difference between two such phrases (the first phrase containing
one fewer asterisk than the second phrase) serves effectively as a fixed adjacency or
proximity condition, with the number of separating words equal to the number of
asterisks in the first phrase. The algorithm integrates over these phrase differentials
to provide a flexible adjacency or proximity capability (i.e. retrieve all records where
word A and word B are separated by n or fewer words in at least one location, where
n is the maximum separation desired between A and B in at least one location).

Abstract: Database search strategies for systematic reviews are often developed
subjectively and may miss relevant studies. We examined whether objective methods,
71
originally developed to identify systematic reviews, could be applied to a
multidisciplinary topic, alcohol-impaired driving (AID). We performed
word-frequency analyses of titles/abstracts/keywords on citations randomly selected
from a ‘gold standard’ database of 131 controlled studies evaluating AID
interventions. Identified words were tested in the Web of Science databases for
sensitivity, precision, and feasibility. Words meeting varying sensitivity and
precision thresholds were combined into search strategies. All threshold
combinations with cumulative sensitivity of at least 75% retrieved 2:100,000
citations. The word frequency-based procedure was therefore modified, first by
eliminating nonspecific words, then by categorizing and combining the remaining
words. With these modifications, sensitivity was 80.0% and precision 4.4%,
retrieving 17,565 citations. Against a validation set, sensitivity was 85.7% and
precision 3.5%. To identify studies on multidisciplinary topics, objective methods
may be useful initially but may need to be modified to meet sensitivity and feasibility
targets.

Abstract: Scientometrics cannot offer a simple consistent method for measuring the

found applicable for evaluating publications of senior scientists with similar

journal papers, and the number of citations obtained by the most frequently cited
papers - are suggested and tested to demonstrate the advantages and disadvantages of
such indexes. The results indicate that calculating scientometric indexes for
individuals, self-citations should be excluded and the effect of the different
bibliometric features of the field should be taken into account. The correctness of the
indexes used for evaluating journal papers of individuals should be investigated also
on the individual level.

Abstract: The ‘Author’s Effect of Showcasing’ (AES) is the activity of publishing
authors who shape by their own free will the formal reference stock of their
communications, placing this stock into the showcase of science. This paper reports
the results of a decisive control test of the existence of the AES, processing 1175
historically synchronous physics conference communications. Applying methods of
bibliometrics and science philology, the manifestation of the AES phenomenon is
demonstrated and analysed in this theoretically most homogeneous domain of
scientific literature. The widely differing documentedness in the communications of
conferences held on particular topics of physics, especially the great differences in
the size of the formal reference stocks in all extent categories of the communications
depends solely on the person of the authors. This generally extremely heterogeneous
documentedness is therefore valid evidence of the existence of the effect and its
effective operation in the scientific literature. The correctness of the AES doctrine,
including the correctness of two additional theses, has been demonstrated.

Abstract: Bibliometrics has changed out of all recognition since 1958; becoming
established as a field, being taught widely in library and information science schools,
and being at the core of a number of science evaluation research groups around the
world. This was all made possible by the work of Eugene Garfield and his Science
Citation Index. This article reviews the distance that bibliometrics has travelled since
1958 by comparing early bibliometrics with current practice, and by giving an
overview of a range of recent developments, such as patent analysis, national
research evaluation exercises, visualization techniques, new applications, online
citation indexes, and the creation of digital libraries. Webometrics, a modern, fastgrowing offshoot of bibliometrics, is reviewed in detail. Finally, future prospects are
discussed with regard to both bibliometrics and webometrics.

comparison with the Web of Science (WOS). In particular we want to explore if the
outcome of bibliometric analyses differs between Scopus and WOS and, if yes, in
which aspects. Since journal indicators vary among disciplines, we analysed only
journals from the subject pharmacy and pharmaceutical sciences. Nonetheless, our
study has also broader implications. Its major findings are: (a) Each top- 100 JCR
pharmacy journal was covered by Scopus. (b) The impact factor was higher for 82
and the immediacy index greater for 78 journals in Scopus in 2005. Pharmacy
journals with a high impact factor in the JCR usually have a high impact factor in
Scopus. (c) Several medium impact journals could be identified in Scopus which
were not reported in JCR. (d) The two databases differed in the number of articles
within a tolerable margin of deviation for most journals.

Abstract: This article addresses the robustness of country-by-country rankings
according to the number of published articles and their average citation impact in the
field oncology. It compares rankings based on bibliometric indicators derived from
the Web of Science (WoS) with those calculated from Scopus. It is found that the
oncological journals in Scopus not covered by WoS tend to be nationally oriented
journals, i.e. they mainly serve a national research community, and play as of yet a
more peripheral role in the international journal communication system. In
expanding the set of WoS journals with Scopus journals not indexed for WoS, the
countries that profit most in terms of percentage of published documents tend to
show a decline in their average citation rate. This paradoxical finding is further
explained by mathematical-statistical considerations, and interpreted as a short term
effect. The paper discusses its implications for the construction of bibliometric
indicators.

Abstract: There are several simple and sophisticated scientometric indicators generally
applied in the literature (e.g. total number of publications and citations, citations per
journal paper, relative citedness indexes, Hirsch index, etc.), which may characterize
the publications of scientists both qualitatively and quantitatively. The calculation
methods generally use data referring to the total set of papers studied. Scientific
progress, however, may be attributed primarily to information in the highly cited
publications. Therefore, a new indicator (-index) is suggested for comparative
assessment of scientists active in similar subject fields. The pi-index is equal to one
hundredth of the number of citations obtained to the top square root of the total
number of journal papers (‘elite set of papers’) ranked by the decreasing number of
citations. The relation of the -index to other indexes and its dependence on the field
is studied, using data of journal papers of ‘highly cited researchers’.

Abstract: Collaboration patterns among scientists are becoming more and more
complicated. Even sophisticated methods for taking the number of co-authors into
account do not solve all problems related to the calculation of citation measures such
as the h-index. In this article we introduce role-based h-indices and in particular the
major contribution h-index, denoted as h-maj, which takes only those articles into
account in which the scientist plays a major or core role. As an example we provide
major contribution indices for scientists in the health sciences in China. Differences
between the h-index and h-maj are shown for data based on the Web of Science
(WoS), and separately, based on the China National Knowledge Infrastructure
(CNKI) database. It is suggested to use the major contribution h-index as a
supplementary index, especially in those fields where multiple ‘first authors’ and/or
corresponding authors are common.

Abstract: This study provides an historical analysis of the discipline of information
retrieval (IR) for three time periods: 1980-1984, 1990-1994 and 2000-2004. This
analysis is done through the use of a novel bibliometric technique called
tri-occurrence analysis, in which the descriptor ‘information retrieval’ is used as a
filter term within the traditional technique of co-occurrence analysis. The resulting
data is visualized by means of Pathfinder Network analysis. The findings provide
evidence of an evolution in the IR landscape over the three decades from an
emphasis on systems-, storage- and education-related research in the 1980s to
database-, user interface- and information service-related research in the 1990s and
to web-related research in the 2000s. This work provides additional validation of the
use of tri-occurrence analysis as a useful bibliometric technique.

Abstract: This study uses two bibliometric methods, direct citation and co-authorship, to
investigate the interdisciplinary changes in information sciences during 1978-2007.
The disciplines of references and co-authors from five information science journals
were analysed. Furthermore, Brillouin’s Index was adopted to measure the degree of
interdisciplinarity. The study revealed that information science researchers have cited
the publications of library and information science (LIS) most frequently. The
co-authors of information science articles are also primarily from the discipline of
LIS, but the percentage of references to LIS is much higher. This indicates that
information science researchers mainly rely on publications in LIS, and they often
77
produce scientific papers with researchers from LIS. The discipline rankings
generated by direct citation and co-authorship show a significant consistency via
Spearman’s correlation coefficient test. The interdisciplinary degree of information
science has displayed growth. In particular, the degree of interdisciplinarity for
co-authors has grown.

Abstract: This study seeks to understand the scientific communication activities of
Libyan scientists, and their engagement with scientific publishing. The research
embraces both formal and informal communication, and explores that behaviour in
the context of a developing country, Libya. A mixed methods approach including
desk research, a bibliometric study of recent scientific output, interviews with key
informants, and a questionnaire survey with scientists is used to gather rich data and
to generate deep insights into scientific communication behaviours. Findings suggest
that Libyan scientists affirm the centrality of scientific communication to successful
science, but that the nature of communication is influenced by national and other
cultures, and in particular, Libyan scientists value informal scientific communication.
They also both access and publish in e-journals and in open access sources but are
aware of a range of barriers to scientific communication in the digital age.

78
analysis of the methods used to provide useful information and guidance for those
who may wish to undertake similar studies, and is of particular relevance for the
academic disciplines which have publication and citation norms that may not
perform well using traditional tools. Scopus and Google Scholar are discussed and a
detailed comparison of the effects of different search methods and cleaning methods
within and between these tools for subject and author analysis is provided. The
additional database capabilities and usefulness of ‘Scopus More’ in addition to
‘Scopus General’ are discussed and evaluated. Scopus paper coverage is found to
favourably compare with Google Scholar but Scholar consistently has superior
performance at finding citations to those papers. These additional citations
significantly increase the citation totals and also change the relative ranking of
papers. Publish or Perish, a software wrapper for Google Scholar, is also examined
and its limitations and some possible solutions are described. Data cleaning methods,
including duplicate checks, expert domain checking of bibliographic data, and
content checking of retrieved papers, are compared and their relative effects on paper
and citation count discussed. Google Scholar and Scopus are also compared as tools
for collecting bibliographic data for visualizations of developing trends and, owing to
the comparative ease of collecting abstracts, Scopus is found far more effective.

Abstract: It is assumed that a paper which cites an earlier document shares a subject
relationship with that particular document. In order to determine if this assumption is
valid, a study was conducted by analysing 1000 articles from the Science Citation
Index and Social Sciences Citation Index. These articles were selected in ten
different disciplines by using a purposive sampling technique. Various Spearman’s
Correlation Coefficient tests were computed to find out if a subject relationship
existed between the articles which have the same keywords in their titles (parent
articles and related records). Through the analysis the hypothesis has been verified
showing that there is a relationship between the articles which are citing the same
references. This was determined by co-occurrences of the same keywords among the
shared references. However, there are some unique differences in the science and the
social science disciplines that exist in these two databases.

Abstract: There is a plethora of theories to explore the disciplines of business,
management and sociology, with institutional theory being widely used to explore a
range of research challenges. In the area of Information Systems (IS), the use of
institutional theory remains in its infancy, with much potential for adoption. Much of
the rationale underpinning the proposed research is that a systematic review and
synthesis of the normative literature may support the direction of further research and
the use of institutional theory in exploring pertinent research challenges facing the IS
community. This study also serves to signpost cross-disciplinary research, and thus
opens up a whole new research paradigm. Therefore, this article seeks to provide a
bibliometric analysis and a comprehensive and systematic review of the literature
pertaining to institutional theory to ascertain the current ‘state of play’ of the theory.
Information on a series of variables was extracted after conducting a review of 511
articles across various disciplines that have utilised institutional theory, published in
210 peer-reviewed journals between 1978 and 2008. The findings suggest that the
positivist paradigm, empirical and quantitative research, the survey method and
organisation/firm as a unit of analysis was used predominantly in combination with
institutional theory. The results of this study may have implications for researchers,
journal editors, reviewers and universities. Journal of Information Technology (2009)

Abstract: This paper investigates the mechanism of the Journal Impact Factor (JIF).
Although created as a journal selection tool the indicator is probably the central
quantitative indicator for measuring journal quality. The focus is journal
self-citations as the treatment of these in analyses and evaluations is highly disputed.
The role of self-citations (both self-citing rate and self-cited rate) is investigated on a
larger scale in this analysis in order to achieve statistical reliable material that can
further qualify that discussion. Some of the hypotheses concerning journal
self-citations are supported by the results and some are not. (c) 2006 Elsevier Ltd.

it possible to analyse dynamic aspects of the method, and proves sufficiently large to
also obtain stable patterns for each of the disciplines. The theoretical findings are
supplemented by regularities derived from the long-term observations.

Abstract: Evolution of information production processes (IPPs) can be described by a
general transformation function for the sources and for the items. It generalises the
Fellman-Jakobsson transformation which only works on the items. In this paper the
84
dual informetric theory of this double transformation, defined by the rank-frequency
function, is described by, e.g. determining the new size-frequency function. The
special case of power law transformations is studied thereby showing that a Lotkaian
system is transformed into another Lotkaian system, described by a new Lotka
exponent. We prove that the new exponent is smaller (larger) than the original one if
and only if the change in the sources is smaller (larger) than that of the items.
Applications to the study of the evolution of networks are given, including cases of
deletion of nodes and/or links but also applications to other fields are given. (c) 2007

Abstract: A model is proposed for the creation and transmission of scientific knowledge,
based on the network of citations among research articles. The model allows to
assign to each article a non-negative value for its creativity, i.e. its creation of new
knowledge. If the entire publication network is truncated to the first neighbors of an
article (the n references that it makes and the m citations that it receives), its
creativity value becomes a simple function of n and m. After splitting the creativity
of each article among its authors, the cumulative creativity of an author is then
proposed as an indicator of her or his merit of research. In contrast with other merit
indicators, this creativity index yields similar values for the top scientists in two very
different areas (life sciences and physics), thus offering good promise for
interdisciplinary analyses. (c) 2007 Elsevier Ltd. All rights reserved.

Abstract: Really simple syndication (RSS) is becoming a ubiquitous technology for
notifying users of new content in frequently updated web sites, such as blogs and
news portals. This paper describes a feature-based, local clustering approach for
generating over-view timelines for major events, such as the tsunami tragedy, from a
general-purpose corpus of RSS feeds. In order to identify significant events, we
automatically (1) selected a set of significant terms for each day; (2) built a set of
(term-co-term) pairs and (3) clustered the pairs in an attempt to group contextually
85
related terms. The clusters were assessed by 10 people, finding that the average
percentage apparently representing significant events was 68.6%. Using these
clusters, we generated overview timelines for three major events: the tsunami tragedy,
the US election and bird flu. The results indicate that our approach is effective in
identifying predominantly genuine events, but can only produce partial timelines. (c)

Abstract: Researchers worldwide are increasingly being assessed by the citation rates of
their papers. These rates have potential impact on academic promotions and funding
decisions. Currently there are several different ways that citation rates are being
calculated, with the state of the art indicator being the crown indicator. This indicator
has flaws and improvements could be considered. An item oriented field normalized
citation score average ((c) over bar (f)) is an incremental improvement as it differs
from the crown indicatorin so much as normalization takes place on the level of
individual publication (or item) rather than on aggregated levels, and therefore
assigns equal weight to each publication. The normalization on item level also makes
it possible to calculate the second suggested indicator: total field normalized citation
score (Sigma c(f)). A more radical improvement (or complement) is suggested in the
item oriented field normalized logarithm-based citation z-score average ((c) over bar
(fz[ln]) or citation z-score). This indicator assigns equal weight to each included
publication and takes the citation rate variability of different fields into account as
well as the skewed distribution of citations over publications. Even though the
citation z-score could be considered a considerable improvement it should not be
used as a sole indicator of research performance. Instead it should be used as one of
many indicators as input for informed peer review. (c) 2007 Elsevier Ltd. All rights

Abstract: The Web of Science is no longer the only database which offers citation
indexing of the social sciences. Scopus, CSA Illumina and Google Scholar are new
entrants in this market. The holdings and citation records of these four databases
were assessed against two sets of data one drawn from the 2001 Research
Assessment Exercise and the other from the International bibliography of the Social
Sciences. Initially, CSA Illumina’s cove-rage at journal title level appeared to be the
most comprehensive. But when recall and average citation count was tested at article
level and rankings extrapolated by submission frequency to individual journal titles,
Scopus was ranked first. When issues of functionality, the quality of record
processing and depth of coverage are taken into account, Scopus and Web of Science
have a significant advantage over the other two databases. From this analysis, Scopus
offers the best coverage from amongst these databases and could be used as an
alternative to the Web of Science as a tool to evaluate the research impact in the
social sciences. (c) 2007 Charles Oppenheim. Published by Elsevier Ltd. All rights

? Burrell, Q.L. (2007), On the h-index, the size of the Hirsch core and Jin’s A-index.
Journal of Informetrics, 1 (2), 170-177.
Full Text: 2007\J Inf1, 170.pdf
Abstract: Hirsch’s h-index seeks to give a single number that in some sense summarizes
an author’s research output and its impact. Essentially, the h-index seeks to identify
the most productive core of an author’s output in terms of most received citations.
This most productive set we refer to as the Hirsch core, or h-core. Jin’s A-index
relates to the average impact, as measured by the average number of citations, of this
87
“most productive” core. In this paper, we investigate both the total productivity of
the Hirsch core - what we term the size of the h-core - and the A-index using a
previously proposed stochastic model for the publication/citation process,
emphasising the importance of the dynamic, or time-dependent, nature of these
measures. We also look at the inter-relationships between these measures. Numerical
investigations suggest that the A-index is a linear function of time and of the h-index,
while the size of the Hirsch core has an approximate square-law relationship with
time, and hence also with the A-index and the h-index. (c) 2007 Elsevier Ltd. All

output using statistical quantile plotting. Journal of Informetrics, 1 (3), 185-192.
Full Text: 2007\J Inf1, 185.pdf
Abstract: In this paper, we propose two methods for scoring scientific output based on
statistical quantile plotting. First, a resealing of journal impact factors for scoring
scientific output on a macro level is proposed. It is based on normal quantile plotting
which allows to transform impact data over several subject categories to a
standardized distribution. This can be used in comparing scientific output of larger
entities such as departments working in quite different areas of research. Next, as an
alternative to the Hirsch index [Hirsch, J.E. (2005). An index to quantify an
individuals scientific research output. Proceedings of the National Academy of
Sciences of the United States of America, 102(46), 16569-16572], the extreme value
index is proposed as an indicator for assessment of the research performance of
individual scientists. In case of Lotkaian-Zipf-Pareto behaviour of citation counts of
an individual, the extreme value index can be interpreted as the slope in a Pareto-Zipf
quantile plot. This index, in contrast to the Hirsch index, is not influenced by the
number of publications but stresses the decay of the statistical tail of citation counts.
It appears to be much less sensitive to the science field than the Hirsch index. (c)

Abstract: The relationship of the h-index with other bibliometric indicators at the micro
level is analysed for Spanish CSIC scientists in Natural Resources, using
publications downloaded from the Web of Science (1994-2004). Different activity
and impact indicators were obtained to describe the research performance of
scientists in different dimensions, being the h-index located through factor analysis
in a quantitative dimension highly correlated with the absolute number of
publications and citations. The need to include the remaining dimensions in the
analysis of research performance of scientists and the risks of relying only on the
h-index are stressed. The hypothesis that the achievement of some highly visible but
intermediate-productive authors might be underestimated when compared with other
scientists by means of the h-index is tested. (c) 2007 Elsevier Ltd. All rights

research output. Proceedings of the National Academy of Sciences of the United
States of America, 102(46), 16569-16572] has proposed the h index as a
single-number criterion to evaluate the scientific output of a researcher. We
investigated the convergent validity of decisions for awarding long-term fellowships
to post-doctoral researchers as practiced by the Boehringer Ingelheim Fonds (B.I.F.)
by using the h index. Our study examined 414 B.I.F. applicants (64 approved and
350 rejected) with a total of 1586 papers. The results of our study show that the
applicants’ h indices correlate substantially with standard bibliometric indicators.
Even though the h indices of approved B.I.F. applicants on average (arithmetic mean
89
and median) are higher than those of rejected applicants (and with this,
fundamentally confirm the validity of the funding decisions), the distributions of the
h indices show in part overlaps that we categorized as type I error (falsely drawn
approval) or type II error (falsely drawn rejection). Approximately, one-third of the
decisions to award a fellowship to an applicant show a type I error, and about
one-third of the decisions not to award a fellowship to an applicant show a type II
error. Our analyses of possible reasons for these errors show that the applicant’s field
of study but not personal ties between the B.I.F. applicant and the B.I.F. can increase
or decrease the risks for type I and type II errors. (c) 2007 Elsevier Ltd. All rights

Abstract: Never before in history has mankind produced and had access to so much data,
information, knowledge, and expertise as today. To organize, access, and manage
these valuable assets effectively, we use taxonomies, classification hierarchies,
ontologies, controlled vocabularies, and other approaches. We create directory
structures for our files. We use organizational hierarchies to structure our work
environment. However, the design and continuous update of these organizational
schemas with potentially thousands of class nodes organizing millions of entities is
challenging for any human being. The taxonomy visualization and validation (TV)
tool introduced in this paper supports the semi-automatic validation and optimization
of organizational schemas such as file directories, classification hierarchies,
taxonomies, or other structures imposed on a data set for organization, access, and
naming. By showing the “goodness of fit” for a schema and the potentially millions
of entities it organizes, the TV tool eases the identification and reclassification of
misclassified information entities, the identification of classes that grow too large,
the evaluation of the size and homogeneity of existing classes, the examination of the
“well-formedness” of an organizational schema, and more. As a demonstration, the
TV tool is applied to display and examine the United States Patent and Trademark
Office patent classification, which organizes more than three million patents into
about 160,000 distinct patent classes. The paper concludes with a discussion and an
90
outlook to future work. (c) 2007 Elsevier Ltd. All rights reserved.

Full Text: 2007\J Inf1, 239.pdf
Abstract: The last few years have seen the emergence of several open access options in
scholarly communication which can broadly be grouped into two areas referred to as
‘gold’ and ‘green’ open access (OA). In this article we review the literature
examining the relationship between OA status and citation counts of scholarly
articles. Early studies showed a correlation between the free online availability or
OA status of articles and higher citation counts, and implied causality without due
consideration of potential confounding factors. More recent investigations have
dissected the nature of the relationship between article CA status and citations. Three
non-exclusive postulates have been proposed to account for the observed citation
differences between OA and non-OA articles: an open access postulate, a selection
bias postulate, and an early view postulate. The most rigorous study to date (in
condensed matter physics) showed that, after controlling for the early view postulate,
the remaining difference in citation counts between OA and non-OA articles is
explained by the selection bias postulate. No evidence was found to support the OA
postulate per se; i.e. article OA status alone has little or no effect on citations. Further
studies using a similarly rigorous approach are required to determine the generality
91
of this finding. (c) 2007 Elsevier Ltd. All rights reserved.

documents: A new type of informetrics theory. Journal of Informetrics, 1 (4),
257-268.
Full Text: 2007\J Inf1, 257.pdf
Abstract: A probabilistic model is presented to estimate the number of lost multi-copy
documents, based on retrieved ones. For this, we only need the number of retrieved
documents of which we have one copy and the number of retrieved documents of
which we have two copies. If we also have the number of retrieved documents of
which we have three copies then we are also able to estimate the number of copies of
the documents that ever existed (assumed that this number is fixed over all
documents). Simulations prove the stability of the model. The model is applied to the
estimation of the number of lost printed programmes of Jesuit theatre plays in the
Provincia Flandro-Belgica before 1773. This Jesuit province was an administrative
entity of the order, which was territorially slightly larger in extent than present day
Flanders, the northern, Dutch-speaking part of Belgium. It is noted that the functional
model P-j for the fraction of retrieved documents with j copies is a size-frequency
function satisfying (Pj+1/P-j)/(P-j/Pj-1)<1 for all j. It is further noted that the
“classical” size-frequency functions are different: Lotka’s function satisfies the
opposite inequality and the decreasing exponential one gives always 1 for the above
ratio, hence showing that we are in a new type of informetrics theory. We also
provide a mathematical rationale for the “book historical law” stating that the
92
probability to lose a copy of a multi-copy document (i.e. an edition) is an increasing
function of the size of the edition. The paper closes with some open problems and a
description of other potential applications of this probabilistic model. (c) 2007

Abstract: Under the National Innovation System (NIS) framework, knowledge stock has
been recognized as a key factor for enhancing national innovative capabilities.
However, despite the importance of patents and papers for measuring knowledge,
previous research has not fully utilized patent and paper databases, and has instead
relied on research and development (R&D) data. Therefore, in this research, I
introduce a way to utilize both types of useful data when measuring industrial
knowledge stocks. As primary data sources, the United States Patent and Trademark
Office (USPTO) Web site for patents and the science citation index (SCI) for papers
are used. In the case of Korea, the amount of knowledge stock proxied by patents and
papers is different from that proxied by R&D, which indicates in turn that using a
single indicator such as R&D may be misleading. Although the result may vary
depending on the selected nation, the proposed method will be useful for gauging
knowledge stocks in a more complementary way. (c) 2007 Elsevier Ltd. All rights

Full Text: 2007\J Inf1, 277.pdf
Abstract: We focus on the statistics of word occurrences and of the waiting times
between such occurrences in Blogs. Due to the heterogeneity of words’ frequencies,
the empirical analysis is performed by studying classes of “frequently-equivalent”
words, i.e. by grouping words depending on their frequencies. Two limiting cases are
considered: the dilute limit, i.e. for those words that are used less than once a day,
and the dense limit for frequent words. In both cases, extreme events occur more
frequently than expected from the Poisson hypothesis. These deviations from Poisson
statistics reveal non-trivial time correlations between events that are associated with
93
bursts of activities. The distribution of waiting times is shown to behave like a
stretched exponential and to have the same shape for different sets of words sharing a
common frequency, thereby revealing universal features. (c) 2007 Elsevier Ltd. All

Full Text: 2007\J Inf1, 287.pdf
Abstract: Based on previous findings and theoretical considerations, it was suggested
that bibliographic coupling could be combined with a cluster method to provide a
method for science mapping, complementary to the prevailing co-citation cluster
analytical method. The complete link cluster method was on theoretical grounds
assumed to provide a suitable cluster method for this purpose. The objective of the
study was to evaluate the proposed method’s capability to identify coherent research
themes. Applying a large multidisciplinary test bed comprising more than 600,000
articles and 17 million references, the proposed method was tested in accordance
with two lines of mapping. In the first line of mapping, all significant (strong) links
connecting ‘core documents’ (strongly and frequently coupled documents) in clusters
with any other core document was mapped. This resulted in a depiction of all
significant artificially broken links between core documents in a cluster and core
documents extrinsic to that cluster. The second line of mapping involved the
application of links between clusters only. They were used to successively merge
clusters on two subsequent levels of fusion, where the first generation of clusters
were considered objects for a second clustering, and the second generation of clusters
gave rise to a final cluster fusion. Changes of cluster composition on the three levels
were evaluated with regard to several variables. Findings showed that the proposed
method could provide with valid depictions of current research, though some severe
restrictions would adhere to its application. (c) 2007 Elsevier Ltd. All rights reserved.

Full Text: 2007\J Inf1, 308.pdf
Abstract: The original Lotka’s Law refers to single scientist distribution, i.e. the
frequency of authors A(i) with i publications per author is a function of i: A(i) =f(i).
However, with increasing collaboration in science and in technology the study of the
94
frequency of pairs or triples of co-authors is highly relevant. Starting with pair
distribution well-ordered collaboration structures of co-author pairs will be presented,
i.e. the frequency of co-author pairs N-ij between authors with i publications per
author and authors with j publications per author is a function of i and j: N-ij =f(i,j)
using the normal count procedure for counting i or j. We have assumed that the
distribution of co-author pairs’ frequencies can be considered to be reflection of a
social Gestalt and therefore can be described by the corresponding mathematical
function based on well-known general characteristics of structures in interpersonal
relations in social networks. We have shown that this model of social Gestalts can
better explain the distribution of co-author pairs than by a simple bivariate function
in analogy to Lotka’s Law. This model is based on both the Gestalt theory and the
old Chinese Yin/Yang theory. (c) 2007 Elsevier Ltd. All fights reserved.

Full Text: 2007\J Inf1, 338.pdf
Abstract: The method of bibliographic coupling in combination with the complete link
cluster method was applied for mapping of the field of organic chemistry with the
purpose of testing the applicability of a proposed mapping method on the field level.
The method put forward aimed at the generation of cognitive cores of documents,
so-called ‘bibliographic cliques’ in the network of bibliographically coupled research
articles. The defining feature of these cliques is that they can be considered complete
graphs where each bibliographic coupling link ties an unordered pair of documents.
In this way, it was presumed that coherent groups of documents in the research front
would be found and that these groups would be intellectually coherent as well.
Statistical analysis and subject specialist evaluations confirmed these presumptions.
The study also elaborates on the choice of observation period and the application of
thresholds in relation to the size of document populations. (c) 2007 Elsevier Ltd. All

the beginning of the 21st century we witness considerable growth in webometrics,
mapping and visualization and open access. A new topic is comparison between
citation databases, as a result of the introduction of two new citation databases
Scopus and Google Scholar. There is renewed interest in indicators as a result of the
introduction of the h-index. Traditional topics like citation analysis and informetric
theory also continue to develop. The impact factor debate, especially outside the
informetric literature continues to thrive. Ranked lists (of journal, highly cited papers
or of educational institutions) are of great public interest. (C) 2007 Elsevier Ltd. All

Abstract: The majority of author cocitation analysis (ACA) have relied on the Institute
for Scientific Information (ISI) citation databases. ISI convention allows only the
retrieval of papers that cite works of which the author is first or sole author.
Non-primary authors (authors whose name appear in second or later position) will
not be counted when assembling a cocitation frequency matrix. Therefore, this has
been a methodological issue in ACA study. This paper empirically examines the
impact of the ISI convention on the results of ACA. Previous research has addressed
and shed light on some parts of methodological issues, but failed to address issues
such as to what extent the use of different approach has resulted in different
outcomes in terms of actual intellectual structure of a given academic discipline.
96
Using our data and cociation matrix generation systems, we compare the differences
in the process and outcomes of using different cocitation matrices. Our study
concludes that all author based ACA is better than first author based ACA to capture
all influential researchers in a field. It also identifies more research subspecialties.
Finally, all Author based ACA and first author based ACA produce little differences
in stress values of MDS outputs. Published by Elsevier Ltd.

1997s paper production. There are clear distinctions among author keywords used in
publications from the five most productive countries (USA, UK, Canada, Germany

Abstract: When carrying out a research project, some materials may not be available
in-house. Thus, investigators resort to external providers for conducting their
research. To that end, the exchange may be formalised through material transfer
agreements. In this context, industry, government and academia have their own
specific expectations regarding compensation for the help they provide when
transferring the research material. This paper assesses whether these contracts might
have had an impact on visibility of researchers. Visibility is thereby operationalised
on the basis of a bibliometric approach. In the sample utilised, researchers that
availed themselves of these contracts were more visible compared to those who did
not use them, controlling for seniority and co-authorship. Nonetheless, providers and
receivers could not be differentiated in terms of visibility but by research sector and
co-authorship. Being a user of these contracts might, to some extent, be the reflection
of systematic differences in the stratification of science based on visibility. (C) 2007

Abstract: Egghe and Proot [Egghe, L., & Proot, G. (2007). The estimation of the
number of lost multi-copy documents: A new type of informetrics theory. Journal of
Informetrics] introduce a simple probabilistic model to estimate the number of lost
multi-copy documents based on the numbers of retrieved ones. We show that their
model in practice can essentially be described by the well-known Poisson
98
approximation to the binomial. This enables us to adopt a traditional maximum
likelihood estimation (MLE) approach which allows the construction of
(approximate) confidence intervals for the parameters of interest, thereby resolving

Abstract: The paper introduces a new journal impact measure called The Reference
Return Ratio (3R). Unlike the traditional Journal Impact Factor (JIF), which is based
on calculations of publications and citations, the new measure is based on
calculations of bibliographic investments (references) and returns (citations). A
comparative study of the two measures shows a strong relationship between the 3R
and the JIF. Yet, the 3R appears to correct for citation habits, citation dynamics, and
composition of document types - problems that typically are raised against the JIF. In
addition, contrary to traditional impact measures, the 3R cannot be manipulated ad
infinitum through journal self-citations. (C) 2007 Elsevier Ltd. All rights reserved.

Abstract: General results on transformations on information production processes (IPPs),
involving transformations of the h-index and related indices, are applied in concrete,
simple cases: doubling the production per source, doubling the number of sources,
doubling the number of sources but halving their production, halving the number of
sources but doubling their production (fusion of sources) and, finally, special cases
of general power law transformations. In each case we calculate concrete
99
transformation formulae for the h-index h (transformed into h*) and we discuss when
we have h* < h, h* = h or h* > h. These results are then extended to some other
h-type indices such as the g-index, the R-index and the weighted h-index. (C) 2007

Abstract: The impact factor of a journal reflects the frequency with which the journal’s
articles are cited. It is the best available measure of journal quality. For calculation of
impact factor, we just count the number of citations, no matter howprestigious the
citing journal is. We think that impact factor as a measure of journal quality, may be
improved if in its calculation, we not only take into account the number of citations,
but also incorporate a factor reflecting the prestige of the citing journals relative to
the cited journal. In calculation of this proposed “weighted impact factor,” each
citation has a coefficient (weight) the value of which is 1 if the citing journal is as
prestigious as the cited journal; is > 1 if the citing journal is more prestigious than the
cited journal; and is < 1 if the citing journal has a lower standing than the cited
journal. In this way, journals receiving many citations from prestigious journals are
considered prestigious themselves and those cited by low-status journals seek little
credit. By considering both the number of citations and the prestige of the citing
journals, we expect the weighted impact factor be a better scientometrics measure of
journal quality. (C) 2008 Elsevier Ltd. All rights reserved.

Abstract: Although it is generally understood that different citation counting methods
can produce quite different author rankings, and although “optimal” author
co-citation counting methods have been identified theoretically, studies that compare
author co-citation counting methods in author co-citation analysis (ACA) studies are
still rare. The present study applies strict all-author-based ACA to the Information
Science (IS) field, in that all authors of all cited references in a classic IS dataset are
counted, and in that even the diagonal values of the co-citation matrix are computed
in their theoretically optimal form. Using Scopus instead of SSCI as the data source,
we find that results from a theoretically optimal all-author ACA appear to be
excellent in practice, too, although in a field like IS where co-authorship levels are
relatively low, its advantages over classic first-author ACA appear considerably
smaller than in the more highly collaborative ones targeted before. Nevertheless, we
do find some differences between the two approaches, in that first-author ACA
appears to favor theorists who presumably tend to work alone, while all-author ACA
appears to paint a somewhat more recent picture of the field, and to pick out some
collaborative author clusters. (C) 2008 Elsevier Ltd. All rights reserved.

Abstract: Informetric researchers have long chafed at the limitations of bibliographic
databases for their analyses, without being able to visualize or develop real solutions
to the problem. This paper describes a solution developed to provide for the
specialist needs of informetric researchers. In a collaborative exercise between the
fields of computer science and informetrics, data modelling was used in order to
address the requirements of complex and dynamic informetric data. This paper
reports on this modelling experience with its aim of building an object-relational
database (ORDB) for informetric research purposes. The paper argues that ORM
(object-relational model) is particularly suitable because it allows for the modelling
of complex data and accommodates the various data source formats and standards
used by a variety of bibliographic databases. Further, ORM captures the dynamic
nature of informetric data by allowing user-defined data types and by embedding
basic statistical calculating tools as object functions in these user-defined data types.
The main ideas of the paper are implemented in an Oracle database management

h(alpha)-and g(alpha)-indices on the one hand and some simple measures of
scientific performance on the other hand. We also study the behavior of the
h(alpha)-and g(alpha)-indices empirically. Some advantages of the h(alpha)- and

Abstract: The general aim of this paper is to show the results of a study in which we
combined bibliometric mapping and citation network analysis to investigate the
process of creation and transfer of knowledge through scientific publications. The
novelty of this approach is the combination of both methods. In this case we
analyzed the citations to a very influential paper published in 1990 that contains, for
the first time, the term Absorptive Capacity. A bibliometric map identified the terms
and the theories associated with the term while two techniques from the citation
network analysis recognized the main papers during 15 years. As a result we
identified the articles that influenced the research for some time and linked them into
a research tradition that can be considered the backbone of the “Absorptive Capacity
Field”. (C) 2008 Elsevier Ltd. All rights reserved.

Abstract: This paper reviews a number of studies comparing Thomson Scientific’s Web
of Science (WoS) and Elsevier’s Scopus. It collates their journal coverage in an
important medical subfield: oncology. It is found that all WoS-covered oncological
journals (n = 126) are indexed in Scopus, but that Scopus covers many more journals
(an additional n = 106). However, the latter group tends to have much lower impact
factors than WoS covered journals. Among the top 25% of sources with the highest
impact factors in Scopus, 94% is indexed in the WoS, and for the bottom 25% only
6%. In short, in oncology the WoS is a genuine subset of Scopus, and tends to cover
the best journals from it in terms of citation impact per paper. Although Scopus
covers 90% more oncological journals compared to WoS, the average Scopus-based
impact factor for journals indexed by both databases is only 2.6% higher than that
based on WoS data. Results reflect fundamental differences in coverage policies: the
WoS based on Eugene Garfield’s concepts of covering a selective set of most
frequently used (cited) journals; Scopus with broad coverage, more similar to large
disciplinary literature databases. The paper also found that ‘classical’, WoS-based
impact factors strongly correlate with a new, Scopus-based metric, SCImago
JournalRank (SJR), one of a series of new indicators founded on earlier work by

pursuing self-interested strategies. During the period 2000 - 2005, the network of
global collaborations appears to have reinforced the formation of a core group of
fourteen most cooperative countries. This core group can be expected to use
knowledge from the global network with great efficiency, since these countries have
strong national systems. Countries at the periphery may be disadvantaged by the
increased strength of the core. (C) 2008 Elsevier Ltd. All rights reserved.

Abstract: This paper explores the use of Library Catalog Analysis (LCA), defined as the
application of bibliometric or informetric techniques to a set of library online
catalogs, to describe quantitatively a scientific-scholarly field on the basis of
published book titles. It focuses on its value as a tool in studies of Social Sciences

research performance of its actors. The paper proposes an analogy model between
traditional citation analysis of journal articles and Library Catalog Analysis of book
titles. It presents the outcomes of an exploratory study of book titles in Economics
included in 42 academic library catalogs from 7 countries. It describes the process of
data collection and cleaning, and applies a series of indicators and thematic mapping
techniques. It illustrates how LCA can be fruitfully used to assess book production
and research performance at the level of an individual researcher, a research
department, an entire country and a book publisher. It discusses a number of issues
that should be addressed in follow-up studies and concludes that LCA of published
book titles can be developed into a powerful and useful tool in studies of Social
Sciences and Humanities. (C) 2008 Elsevier Ltd. All rights reserved.

Abstract: Examining a comprehensive set of papers (n = 1837) that were accepted for
publication by the journal Angewandte Chemie International Edition (one of the
prime chemistry journals in the world) or rejected by the journal but then published
elsewhere, this study tested the extent to which the use of the freely available

field of chemistry. Analyses of citations for the set of papers returned by three
fee-based databases - Science Citation Index, Scopus, and Chemical Abstracts - were
compared to the analysis of citations found using GS data. Whereas the analyses
using citations returned by the three fee-based databases show very similar results,
the results of the analysis using GS citation data differed greatly from the findings
using citations from the fee-based databases. Our study therefore supports, on the
one hand, the convergent validity of citation analyses based on data from the
fee-based databases and, on the other hand, the lack of convergent validity of the

Abstract: Governmental initiatives around scientific policy have progressively raised
collaboration to priority status. In this context, a need has arisen to broaden the
traditional approach to the analysis and study of research results by descending to the
group or even the individual scale and supplementing the output-, productivity-,
visibility- and impact-based focus with new measures that emphasize collaboration
from the vantage of structural analysis. To this end, the present paper proposes new
hybrid indicators for the analysis and evaluation of individual research results,
popularity and prestige, that combine bibliometric and structural aspects. A case
study was conducted of the nine most productive departments in Carlos III
University of Madrid. The findings showed hybridization to be a tool sensitive to
traditional indicators, but also to the new demands of modern science as a
self-organized system of interaction among individuals, furnishing information on
researchers’ environments and the behaviour and attitudes adopted within those
environments. (C) 2008 Elsevier Ltd. All rights reserved.

Full Text: 2009\J Inf3, 124.pdf
Abstract: The use of scholarly publications that have not been formally published in e.g.
journals is widespread in some fields. In the past they have been disseminated
through various channels of informal communication. However, the Internet has
enabled dissemination of these un-published and often unrefereed publications to a
much wider audience. This is particularly interesting seen in relation to the highly
disputed open access advantage as the potential advantage for low visibility
publications has not been given much attention in the literature. The present study
examines the role of working papers in economics during a 10-year period
(1996-2005). It shows that working papers are increasingly becoming visible in the
field specific databases. The impact of working papers is relatively low; however,
high impact working paper series have citation rate levels similar to the low impact
journals in the field. There is no tendency to an increase in impact during the 10
years which is the case for the high impact journals. Consequently, the result of this
study does not provide evidence of an open access advantage for working papers in
economics. (C) 2008 Elsevier Ltd. All rights reserved.

combination of quantitative and qualitative studies of science, and (3) the
operationalization of theoretical concepts in terms of measurement and empirical
evidence. Next, three visual conceptualizations of science are discussed and
compared. Each of them provides a framework for the comparison and combination
of existing works, means to combine quantitative and qualitative data, and helps to
operationalize and communicate theoretical concepts using empirical data. Last but
not least, the contributions of and interlinkages among the papers included in this
issue are discussed. (C) 2009 Elsevier Ltd. All rights reserved.

Abstract: While ISSI was founded in 1993, Scientometrics and Bibliometrics are now at
least half a century old. Indeed, the field can be traced to early quantitative studies in
the early 20th century. In the 1930s, it evolved to the “science of science.” The
publication of J.D. Bernal’s Social Function of Science in 1939 was a key transition
point but the field lay dormant until after World War II, when D.J.D. Price’s books
Science Since Babylon and Little Science, Big Science were published in 1961 and
1963. His role as the “Father of Scientometrics” is clearly evident by using the
109
HistCite software to visualize his impact as well as the subsequent impact of the
journal Scientometrics on the growth of the field. Scientometrics owes its name to
V.V. Nalimov, the author of Naukometriya, and to Tibor Braun who adapted the
neologism for the journal. The primordial paper on citation indexing by Garfield

Abstract: We analyze the advent and development of eight scientific fields from their
inception to maturity and map the evolution of their networks of collaboration over
time, measured in terms of co-authorship of scientific papers. We show that as a field
develops it undergoes a topological transition in its collaboration structure between a
small disconnected graph to a much larger network where a giant connected
component of collaboration appears. As a result, the number of edges and nodes in
the largest component undergoes a transition between a small fraction of the total to
a majority of all occurrences. These results relate to many qualitative observations of
the evolution of technology and discussions of the “structure of scientific
revolutions”. We analyze this qualitative change in network topology in terms of
several quantitative graph theoretical measures, such as density, diameter, and
relative size of the network’s largest component. To analyze examples of scientific
discovery we built databases of scientific publications based on keyword and citation
searches, for eight fields, spanning experimental and theoretical science, across areas
as diverse as physics, biomedical sciences, and materials science. Each of the
databases was vetted by field experts and is the result of a bibliometric search
constructed to maximize coverage, while minimizing the occurrence of spurious
records. In this way we built databases of publications and authors for superstring
theory, cosmic strings and other topological defects, cosmological inflation, carbon
nanotubes, quantum computing and computation, prions and scrapie, and H5N1
influenza. We also built a database for a classical example of “pathological” science,
namely cold fusion. All these fields also vary in size and in their temporal patterns of
development, with some showing explosive growth from an original identifiable
110
discovery (e.g. carbon nanotubes) while others are characterized by a slow process of
development (e.g. quantum computers and computation). We show that regardless of
the detailed nature of their developmental paths, the process of scientific discovery
and the rearrangement of the collaboration structure of emergent fields is
characterized by a number of universal features, suggesting that the process of
discovery and initial formation of a scientific field, characterized by the moments of
discovery, invention and subsequent transition into “normal science” may be
understood in general terms, as a process of cognitive and social unification out of
many initially separate efforts. Pathological fields, seemingly, never undergo this
transition, despite hundreds of publications and the involvement of many authors. (C)

Abstract: We propose a research program to analyse spatial aspects of the science
system. First, we provide a review of scientometric studies that already explicitly
take the spatial dimension into account. The review includes studies on (i) the spatial
distribution of research and citations, (II) the existence of spatial biases in
collaboration, citations and mobility, and (iii) the citation impact of national versus
international collaborations. Then, we address a number of methodological issues in
dealing with space in scientometrics. Finally, to integrate spatial and non-spatial
approaches, we propose an analytical framework based on the concept of proximity.
A proximity approach allows for combining hypotheses from different theoretical
perspectives into a single framework. (C) 2009 Elsevier Ltd. All rights reserved.

Abstract: The h-index and some related bibliometric indices have received a lot of
attention from the scientific community in the last few years due to some of their
good properties (easiness of computation, balance between quantity of publications
and their impact and so on). Many different indicators have been developed in order
111
to extend and overcome the drawbacks of the original Hirsch proposal. In this
contribution we present a comprehensive review on the h-index and related
indicators field. From the initial h-index proposal we study their main advantages,
drawbacks and the main applications that we can find in the literature. A description
of many of the h-related indices that have been developed along with their main
characteristics and some of the works that analyze and compare them are presented.
We also review the most up to date standardization studies that allow a fair
comparison by means of the h-index among scientists from different research areas
and finally, some works that analyze the computation of the h-index and related
indices by using different citation databases (ISI Citation Indexes, Google Scholar
and Scopus) are introduced. (C) 2009 Elsevier Ltd. All rights reserved.

Abstract: The prevalence of uncited papers or of highly cited papers, with respect to the
bulk of publications, provides important clues as to the dynamics of scientific
research. Using 25 million papers and 600 million references from the Web of
Science over the 1900-2006 period, this paper proposes a simple model based on a
random selection process to explain the “uncitedness” phenomenon and its decline
over the years. We show that the proportion of cited papers is a function of (1) the
number of articles available (the competing papers), (2) the number of citing papers
and (3) the number of references they contain. Using uncitedness as a departure point,
we demonstrate the utility of the stretched-exponential function and a form of the
Tsallis q-exponential function to fit complete citation distributions over the 20th
century. As opposed to simple power-law fits, for instance, both these approaches are
shown to be empirically well-grounded and robust enough to better understand
citation dynamics at the aggregate level. On the basis of these models, we provide
quantitative evidence and provisional explanations for an important shift in citation
practices around 1960. We also propose a revision of the “citation classic” category
as a set of articles which is clearly distinguishable from the rest of the field. (C) 2009

Abstract: This paper classifies common journal evaluation indicators into three
categories, namely three first-level indicators. They are respectively the indicators on
journal impact, on timeliness, and on journal characteristics. The data used here is
drawn from the medical journals in CSTPCD, a citation database built by the
Institute of Scientific and Technical Information of China. The three categories of
indicators are correlated with one another, so a structural equation may be
established. Then we calculate the value of three first-level indicators and give
subjective weights to the indicators. The comprehensive evaluation upon the medical
journals yields satisfactory results. By simulating the complex relationship among
journal indicators, the structural equation can be used for the estimation of some
implicit indicators and the screening of indicators. This approach provides a new
perspective for scientific and technological evaluation in general sense. It should be
noted that the availability of basic data and the rationality of modeling bear much
upon the evaluation results. (C) 2009 Elsevier Ltd. All rights reserved.

indicators has a limited influence on evaluation results; simplifying indicators can
reduce costs and increase efficiency as well as accuracy of journal evaluation. (C)

Abstract: In response to the call for a science of science policy, we discuss the
contribution of indicators at the macro-level of nations from a scientometric
perspective. In addition to global trends such as the rise of China, one can relate
percentages of world share of publications to government expenditure in academic
research. The marginal costs of improving one’s share are increasing over time.
Countries differ considerably in terms of the efficiency of turning (financial) input
into bibliometrically measurable output. Both funding schemes and disciplinary
portfolios differ among countries. A price per paper can nevertheless be estimated.
The percentages of GDP spent on academic research in different nations are
significantly correlated to historical contingencies such as the percentage of
researchers in the population. The institutional dynamics make strategic objectives
such as the Lisbon objective of the EU - that is, spending 3% of GDP for R&D in
2010 - unrealistic. (C) 2009 Elsevier Ltd. All rights reserved.

Abstract: The citation counts are increasingly used to assess the impact on the scientific
community of publications produced by a researcher, an institution or a country.
There are many institutions that use bibliometric indicators to steer research policy
and for hiring or promotion decisions. Given the importance that counting citations
has today, the aim of the work presented here is to show how citations are distributed
within a scientific area and determine the dependence of the citation count on the
article features. All articles referenced in the Web of Science in 2004 for Biology &
Biochemistry, Chemistry, Mathematics and Physics were considered.
We show that the distribution of citations is well represented by a double
exponential-Poisson law. There is a dependence of the mean citation rate on the
number of co-authors, the number of addresses and the number of references,
although this dependence is a little far from the linear behaviour. For the relation
between the mean impact and the number of pages the dependence obtained was very
low. For Biology & Biochemistry and Chemistry we found a linear behaviour
between the mean citation per article and impact factor and for Mathematics and
Physics the results obtained are near to the linear behaviour.

Full Text: 2010\J Inf4, 23.pdf
Abstract: Bibliometric studies at the micro level are increasingly requested by science
managers and policy makers to support research decisions. Different measures and
indices have been developed at this level of analysis. One type of indices, such as the
h-index and g-index, describe the most productive core of the output of a researcher
and inform about the number of papers in the core. Other indices, such as the a-index
and m-index, depict the impact of the papers in the core. In this paper, we present a
new index which relates two different dimensions in a researcher’s productive core: a
quantitative one (number of papers) and a qualitative one (impact of papers). In such
a way, we could obtain a more balanced and global view of the scientific production
of researchers. This new index, called q2-index, is based on the geometric mean of
h-index and the median number of citations received by papers in the h-core, i.e., the
m-index, which allows us to combine the advantages of both kind of indices.

Abstract: The status of a journal is commonly determined by two factors: popularity and
prestige. While the former counts citations, the latter recursively weights them with
the prestige of the citing journals. We make a thorough comparison of the
bibliometric concepts of popularity and prestige for journals in the sciences and in
the social sciences. We find that the two notions diverge more for the hard sciences,
including physics, engineering, material sciences, and computer sciences, than they
do for the geosciences, for biology-medical disciplines, and for the social sciences.
Moreover, we identify the science and social science journals with the highest
diverging ranks in popularity and prestige compilations.

associated to the authors of the journal articles. This tool allows defining a reference
profile of the typical author of a journal, compare different journals within the same
scientific field, and provide a rough indication of prestige/reputation of a journal in
the scientific community. h-Spectrum can be associated to every journal. Ten
specific journals in the Quality Engineering/Quality Management field are analyzed
so as to preliminarily investigate the h-spectrum characteristics. (C) 2009 Elsevier

Abstract: This paper introduces a new approach to describe the spread of research topics
across disciplines using epidemic models. The approach is based on applying
individual-based models from mathematical epidemiology to the diffusion of a
research topic over a contact network that represents knowledge flows over the map
of science—as obtained from citations between ISI Subject Categories. Using
116
research publications on the protein class kinesin as a case study, we report a better
fit between model and empirical data when using the citation-based contact network.
Incubation periods on the order of 4–15.5 years support the view that, whilst research
topics may grow very quickly, they face difficulties to overcome disciplinary
boundaries.

Abstract: Previous research has shown that citation data from different types of Web

combined Integrated Online Impact (IOI) indicator. For a case study, we selected
research articles published in the Journal of the American Society for Information

citation counts from Web of Science (WoS) and Scopus with five online sources of
citation data including Google Scholar, Google Books, Google Blogs, PowerPoint
presentations and course reading lists. The mean and median IOI was nearly twice as
high as both WoS and Scopus, confirming that online citations are sufficiently
numerous to be useful for the impact assessment of research. We also found
significant correlations between conventional and online impact indicators,
confirming that both assess something similar in scholarly communication. Further
analysis showed that the overall percentage for unique Google Scholar citations
outside the WoS were 73% and 60% for the articles published in JASIST and
Scientometrics, respectively. An important conclusion is that in subject areas where
wider types of intellectual impact indicators outside the WoS and Scopus databases
are needed for research evaluation, IOI can be used to help monitor research
performance.

Abstract: The public sharing of primary research datasets potentially benefits the
research community but is not yet common practice. In this pilot study, we analyzed
whether data sharing frequency was associated with funder and publisher
requirements, journal impact factor, or investigator experience and impact. Across
397 recent biomedical microarray studies, we found investigators were more likely to
publicly share their raw dataset when their study was published in a high-impact
journal and when the first or last authors had high levels of career experience and
impact. We estimate the USA’s National Institutes of Health (NIH) data sharing
policy applied to 19% of the studies in our cohort; being subject to the NIH data
sharing plan requirement was not found to correlate with increased data sharing
behavior in multivariate logistic regression analysis. Studies published in journals
that required a database submission accession number as a condition of publication
were more likely to share their data, but this trend was not statistically significant.
These early results will inform our ongoing larger analysis, and hopefully contribute
to the development of more effective data sharing initiatives. (C) 2009 Elsevier Ltd.

Abstract: Latent semantic analysis (LSA) is a relatively new research tool with a wide
range of applications in different fields ranging from discourse analysis to cognitive
science, from information retrieval to machine learning and so on. In this paper, we
chart the development and diffusion of LSA as a research tool using social network
analysis (SNA) approach that reveals the social structure of a discipline in terms of
collaboration among scientists. Using Thomson Reuters’ Web of Science (WoS), we
identified 65 papers with “latent semantic analysis” in their titles and 250 papers in
their topics (but not in titles) between 1990 and 2008. We then analyzed those papers
using bibliometric and SNA techniques such as co-authorship and cluster analysis. It
appears that as the emphasis moves from the research tool (LSA) itself to its
applications in different fields, citations to papers with LSA in their titles tend to
decrease. The productivity of authors fits Lotka’s Law while the network of authors
is quite loose. Networks of journals cited in papers with LSA in their titles and topics
are well connected. (C) 2009 Elsevier Ltd. All rights reserved.

Full Text: 2010\J Inf4, 194.pdf
Abstract: Field delimitation for citation analysis, the process of collecting a set of
bibliographic records with cited-reference information of research articles that
represent a research field, is the first step in any citation analysis study of a research
field. Due to a number of limitations, the commercial citation indexes have long
made it difficult to obtain a comprehensive dataset in this step. This paper discusses
some of the limitations imposed by these databases, and reports on a method to
overcome some of these limitations that was used with great success to delimit an
emerging and highly interdisciplinary biomedical research field, stem cell research.
The resulting field delimitation and the citation network it induces are both excellent.
This multi-database method relies on using PubMed for the actual field delimitation,
and on mapping between Scopus and PubMed records for obtaining comprehensive
119
information about cited-references contained in the resulting literature. This method
provides high-quality field delimitations for citation studies that can be used as
benchmarks for studies of the impact of data collection biases on citation metrics,
and may help improve confidence in results of scientometric studies for an increased
impact of scientometrics on research policy. (C) 2010 Published by Elsevier Ltd.

In both fields, awarded applicants perform on average better than all rejected
applicants. If only the most preeminent rejected applicants are considered in both
fields, they score better than the awardees on citation impact. With regard to
productivity we find differences between the fields. While the awardees in life
sciences outperform on average the most preeminent rejected applicants, the situation
is reversed in social sciences. (C) 2009 Elsevier Ltd. All rights reserved.

Abstract: We performed a thorough comparison of four main indicators of journal
influence, namely 2-year impact factor, 5-year impact factor, eigenfactor and article
influence. These indicators have been recently added by Thomson Reuters to the
Journal Citation Reports, in both science and social science editions, and are thus
available for study and comparison over a sample of significative size. We find that
the distribution associated with the eigenfactor largely differs from the distribution of
120
the other surveyed measures in terms of deviation from the mean, concentration,
entropy, and skewness. Moreover, it is the one that best fits to the lognormal
theoretical model. Surprisingly, the eigenfactor is also the most variable indicator
when computed across different fields of science and social science, while article
influence is the most stable in this respect, and hence the most suitable metric to be
used interdisciplinarily. Finally, the journal rankings provided by impact factors and
article influence are relatively similar and diverge from the one produced by
eigenfactor, which is closer to that given by the total number of received citations. (C)

Full Text: 2010\J Inf4, 265.pdf
Abstract: This paper explores a new indicator of journal citation impact, denoted as
source normalized impact per paper (SNIP). It measures a journal’s contextual
citation impact, taking into account characteristics of its properly defined subject
field, especially the frequency at which authors cite other papers in their reference
lists, the rapidity of maturing of citation impact, and the extent to which a database
used for the assessment covers the field’s literature. It further develops Eugene
Garfield’s notions of a field’s ‘citation potential’ defined as the average length of
references lists in a field and determining the probability of being cited, and the need
in fair performance assessments to correct for differences between subject fields. A
journal’s subject field is defined as the set of papers citing that journal. SNIP is
defined as the ratio of the journal’s citation count per paper and the citation potential
in its subject field. It aims to allow direct comparison of sources in different subject
fields. Citation potential is shown to vary not only between journal subject categories
- groupings of journals sharing a research field - or disciplines (e. g., journals in
mathematics, engineering and social sciences tend to have lower values than titles in
life sciences), but also between journals within the same subject category. For
instance, basic journals tend to show higher citation potentials than applied or
clinical journals, and journals covering emerging topics higher than periodicals in
classical subjects or more general journals. SNIP corrects for such differences. Its
strengths and limitations are critically discussed, and suggestions are made for
further research. All empirical results are derived from Elsevier’s Scopus. (C) 2010

Abstract: The creation of some kind of representations depicting the current state of
Science (or scientograms) is an established and beaten track for many years now.
However, if we are concerned with the automatic comparison, analysis and
understanding of a set of scientograms, showing for instance the evolution of a
scientific domain or a face-to-face comparison of several countries, the task is
titanically complex as the amount of data to analyze becomes huge and complex. In
this paper, we aim to show that graph-based data mining tools are useful to deal with
scientogram analysis. Subdue, the first algorithm proposed in the graph mining area,
has been chosen for this purpose. This algorithm has been customized to deal with
three different scientogram analysis tasks regarding the evolution of a scientific
domain over time, the extraction of the common research categories substructures in
the world, and the comparison of scientific domains between different countries. The
outcomes obtained in the developed experiments have clearly demonstrated the
potential of graph mining tools in scientogram analysis. (C) 2010 Elsevier Ltd. All

scientist. The h_int index reflects broad international recognition of a scientist, and
prevents overrating of a citation record earned chiefly by self-citations or by citations

Full Text: 2010\J Inf4, 358.pdf
Abstract: Slovenia’s Current Research Information System (SICRIS) currently hosts
86,443 publications with citation data from 8359 researchers working on the whole
plethora of social and natural sciences from 1970 till present. Using these data, we
show that the citation distributions derived from individual publications have Zipfian
properties in that they can be fitted by a power law P(x)similar to x(-alpha), with
alpha between 2.4 and 3.1 depending on the institution and field of research.
Distributions of indexes that quantify the success of researchers rather than
individual publications, on the other hand, cannot be associated with a power law.
We find that for Egghe’s g-index and Hirsch’s h-index the log-normal form
P(x)similar to exp[-alnx - b(ln x)(2)] applies best, with a and b depending moderately
on the underlying set of researchers. In special cases, particularly for institutions with
a strongly hierarchical constitution and research fields with high self-citation rates,
exponential distributions can be observed as well. Both indexes yield distributions
with equivalent statistical properties, which is a strong indicator for their consistency
and logical connectedness. At the same time, differences in the assessment of citation
histories of individual researchers strengthen their importance for properly evaluating
the quality and impact of scientific output. (C) 2010 Elsevier Ltd. All rights reserved.

Abstract: The h index is a widely used indicator to quantify an individual’s scientific
research output. But it has been criticized for its insufficient accuracy-the ability to
discriminate reliably between meaningful amounts of research output. As a single
measure it cannot capture the complete information on the citation distribution over a
scientist’s publication list. An extensive data set with bibliometric data on scientists
working in the field of molecular biology is taken as an example to introduce two
approaches providing additional information to the h index: (1) h(2) lower, h(2)
center, and h(2) upper are proposed, which allow quantification of three areas within
a scientist’s citation distribution: the low impact area (h(2) lower), the area captured
by the h index (h(2) center), and the area of publications with the highest visibility
(h(2) upper). (2) Given the existence of different areas in the citation distribution, the
segmented regression model (sRM) is proposed as a method to statistically estimate
the number of papers in a scientist’s publication list with the highest visibility.
However, such sRM values should be compared across individuals with great care.

Abstract: The scientific impact of a publication can be determined not only based on the
number of times it is cited but also based on the citation speed with which its content
is noted by the scientific community. Here we present the citation speed index as a
meaningful complement to the h index: whereas for the calculation of the h index the
impact of publications is based on number of citations, for the calculation of the
speed index it is the number of months that have elapsed since the first citation, the
citation speed with which the results of publications find reception in the scientific
community. The speed index is defined as follows: a group of papers has the index s
if for s of its N-p papers the first citation was at least s months ago, and for the other
(N-p - s) papers the first citation was <= s months ago. (C) 2010 Elsevier Ltd. All

Abstract: This study presents a ranking of 182 academic journals in the field of artificial
intelligence. For this, the revealed preference approach, also referred to as a citation
impact method, was utilized to collect data from Google Scholar. This list was
developed based on three relatively novel indices: h-index, g-index, and hc-index.
These indices correlated almost perfectly with one another (ranging from 0.97 to
0.99), and they correlated strongly with Thomson’s Journal Impact Factors (ranging
from 0.64 to 0.69). It was concluded that journal longevity (years in print) is an
important but not the only factor affecting an outlet’s ranking position. Inclusion in
125
Thomson’s Journal Citation Reports is a must for a journal to be identified as a
leading A+ or A level outlet. However, coverage by Thomson does not guarantee a
high citation impact of an outlet. The presented list may be utilized by scholars who
want to demonstrate their research output, various academic committees, librarians
and administrators who are not familiar with the AI research domain. (C) 2010

Abstract: In a recent work by Anderson, Hankin, and Killworth (2008), Ferrers

weaknesses: an arbitrary scoring system and an illusory increase in discrimination
power compared to h. Subsequently, we propose a new bibliometric tool, the citation
triad (CT), that better exploits the information contained in a Ferrers diagram, giving
a synthetic overview of a scientist’s publication output. The advantages of this new
approach are discussed in detail. Argument is supported by several examples based

Abstract: We study how scholar collaboration varies across disciplines in science, social

quality of coauthored papers. Impact is measured with the aid of citations collected
by papers, while quality is determined by the judgements expressed by peer
reviewers. To this end, we take advantage of the dataset provided by the first-ever
national research assessment exercise of Italian universities, which involved 20
disciplinary areas, 102 research structures, 18,500 research products, and 6661 peer
reviewers. Collaboration intensity neatly varies across disciplines: it is inescapable is
126
most sciences and negligible in most humanities. We measured a general positive
association between cardinality of the author set of a paper and citation count as well
as peer quality of the contribution. The correlation is stronger when the affiliations of
authors are heterogeneous. There exist, however, notable and interesting
counter-examples. (C) 2010 Elsevier Ltd. All rights reserved.

Abstract: This paper studies the correlations between peer review and citation indicators
when evaluating research quality in library and information science (LIS). Forty-two
LIS experts provided judgments on a 5-point scale of the quality of research
published by 101 scholars; the median rankings resulting from these judgments were
then correlated with h-, g- and H-index values computed using three different sources
of citation data: Web of Science (WoS), Scopus and Google Scholar (GS). The two
variants of the basic h-index correlated more strongly with peer judgment than did
the h-index itself; citation data from Scopus was more strongly correlated with the
expert judgments than was data from GS, which in turn was more strongly correlated
than data from WoS; correlations from a carefully cleaned version of GS data were
little different from those obtained using swiftly gathered GS data; the indices from
the citation databases resulted in broadly similar rankings of the LIS academics; GS
disadvantaged researchers in bibliometrics compared to the other two citation
database while WoS disadvantaged researchers in the more technical aspects of
information retrieval; and experts from the UK and other European countries rated
UK academics with higher scores than did experts from the USA. (C) 2010 Elsevier

Abstract: This paper introduces a new impact indicator for the research effort of a
university, (n)h(3). The number of documents or the number of citations obtained by
an institution are used frequently in international ranking of institutions. However,
these are very dependent on the size and this is inducing mergers with the apparent
sole goal of improving the research ranking. The alternative is to use the ratio of the
two measures, the mean citation rate, that is size independent but it has been shown
to fluctuate along the time as a consequence of its dependence on a very small
number of documents with an extremely good citation performance. In the last few
years, the popularity of the Hirsch index as an indicator of the research performance
of individual researchers led to its application to journals and institutions. However,
the original aim of this h index of giving a mixed measure of the number of
documents published and their impact as measured by the citations collected along
the time is totally undesirable for institutions as the overall size may be considered
irrelevant for the impact evaluation of research. Furthermore, the h index when
applied to institutions tends to retain a very small number of documents making all
other research production irrelevant for this indicator. The (n)h(3) index proposed
here is designed to measure solely the impact of research in a way that is independent
of the size of the institution and is made relatively stable by making a 20-year
estimate of the citations of the documents produced in a single year. (C) 2010

Abstract: Recent studies have concluded that American contributions to science
literature have been in relative decline, whereas contributions from other parts of the
world such as the European Union and Asia have increased. Is the same true for the
areas of bibliometrics, informetrics and scientometrics? This study investigates the
growth and geographic distribution of metrics research for the period 1987-2008.
Similar to studies of other disciplines or science in general, the findings reveal that
the United States continues to dominate, but there has been a recent relative decline
in North American contributions overall. European and Asian contributions have
grown substantially. National and institutional collaborations that contribute to this
growth do not necessarily follow close geographic proximity, although European
nations have been more active with international collaborations overall, both within
Europe and elsewhere. (C) 2010 Elsevier Ltd. All rights reserved.

science during the same period. High energy physics is found to be characterised by
a high and stable share of alphabetized multi-authorships during the investigated
period (1990-2007). It is important to be aware of such disciplinary differences when
conducting bibliometric analyses. (C) 2010 Elsevier Ltd. All rights reserved.

Full Text: 2011\J Inf5, 14.pdf
Abstract: Interdisciplinary scientific research (IDR) extends and challenges the study of
science on a number of fronts, including creating output science and engineering
(S&E) indicators. This literature review began with a narrow search for quantitative
measures of the output of IDR that could contribute to indicators, but the authors
expanded the scope of the review as it became clear that differing definitions,
assessment tools, evaluation processes, and measures all shed light on different
aspects of IDR. Key among these broader aspects is (a) the importance of
incorporating the concept of knowledge integration, and (b) recognizing that
integration can occur within a single mind as well as among a team. Existing output
measures alone cannot adequately capture this process. Among the quantitative
measures considered, bibliometrics (co-authorships, co-inventors, collaborations,
references, citations and co-citations) are the most developed, but leave considerable
gaps in understanding of the social dynamics that lead to knowledge integration.
Emerging measures in network dynamics (particularly betweenness centrality and
diversity), and entropy are promising as indicators, but their use requires
sophisticated interpretations. Combinations of quantitative measures and qualitative
assessments being applied within evaluation studies appear to reveal IDR processes
but carry burdens of expense, intrusion, and lack of reproducibility year-upon-year.
This review is a first step toward providing a more holistic view of measuring IDR,
although research and development is needed before metrics can adequately reflect
the actual phenomenon of IDR. (C) 2010 Published by Elsevier Ltd.

Abstract: The crown indicator is a well-known bibliometric indicator of research
performance developed by our institute. The indicator aims to normalize citation
counts for differences among fields. We critically examine the theoretical basis of the
normalization mechanism applied in the crown indicator. We also make a
comparison with an alternative normalization mechanism. The alternative
mechanism turns out to have more satisfactory properties than the mechanism
applied in the crown indicator. In particular, the alternative mechanism has a
so-called consistency property. The mechanism applied in the crown indicator lacks
this important property. As a consequence of our findings, we are currently moving
towards a new crown indicator, which relies on the alternative normalization
mechanism. (C) 2010 Elsevier Ltd. All rights reserved.

Full Text: 2011\J Inf5, 48.pdf
Abstract: This paper introduces a novel methodology for comparing the citation
distributions of research units of a certain size working in the same homogeneous
field. Given a critical citation level (CCL), we suggest using two real valued
indicators to describe the shape of any distribution: a high-impact and a low-impact
measure defined over the set of articles with citations above or below the CCL. The
key to this methodology is the identification of a citation distribution with an income
distribution. Once this step is taken, it is easy to realize that the measurement of
low-impact coincides with the measurement of economic poverty. In turn, it is
equally natural to identify the measurement of high-impact with the measurement of
a certain notion of economic affluence. On the other hand, it is seen that the ranking
of citation distributions according to a family of low-impact measures is essentially
characterized by a number of desirable axioms. Appropriately redefined, these same
131
axioms lead to the selection of an equally convenient class of decomposable
high-impact measures. These two families are shown to satisfy other interesting
properties that make them potentially useful in empirical applications, including the
comparison of research units working in different fields. (C) 2010 Elsevier Ltd. All

groups within the same discipline, by means of some Hirsch (h) based bibliometric
indicators. Precisely, five different typologies of indicators are used so as to depict
groups’ bibliometric positioning within the scientific community. A specific analysis
concerning the Italian researchers in the scientific sector of Production Technology
and Manufacturing Systems is developed. The analysis is supported by empirical
data and can be extended to research groups associated to other scientific sectors. (C)

Abstract: A citation-based indicator for interdisciplinarity has been missing hitherto
among the set of available journal indicators. In this study, we investigate network
indicators (betweenness centrality), unevenness indicators (Shannon entropy, the
Gini coefficient), and more recently proposed Rao-Stirling measures for
“interdisciplinarity.” The latter index combines the statistics of both citation
distributions of journals (vector-based) and distances in citation networks among
journals (matrix-based). The effects of various normalizations are specified and
measured using the matrix of 8207 journals contained in the Journal Citation Reports
of the (Social) Science Citation Index 2008. Betweenness centrality in symmetrical
(1-mode) cosine-normalized networks provides an indicator outperforming
betweenness in the asymmetrical (2-mode) citation network. Among the
vector-based indicators, Shannon entropy performs better than the Gini coefficient,
but is sensitive to size. Science and Nature, for example, are indicated at the top of
the list. The new diversity measure provides reasonable results when (1 - cosine) is
assumed as a measure for the distance, but results using Euclidean distances were
difficult to interpret. (C) 2010 Elsevier Ltd. All rights reserved.

normalization baseline on relative performance with respect to citation impact: A
case study of 20 natural science departments. Journal of Informetrics, 5 (1), 101-113.
Full Text: 2011\J Inf5, 101.pdf
Abstract: In this paper we study the effects of field normalization baseline on relative
performance of 20 natural science departments in terms of citation impact. Impact is
studied under three baselines: journal, ISI/Thomson Reuters subject category, and
Essential Science Indicators field. For the measurement of citation impact, the
133
indicators item-oriented mean normalized citation rate and Top-5% are employed.
The results, which we analyze with respect to stability, show that the choice of
normalization baseline matters. We observe that normalization against publishing
journal is particular. The rankings of the departments obtained when journal is used
as baseline, irrespective of indicator, differ considerably from the rankings obtained
when ISI/Thomson Reuters subject category or Essential Science Indicators field is
used. Since no substantial differences are observed when the baselines Essential
Science Indicators field and ISI/Thomson Reuters subject category are contrasted,
one might suggest that people without access to subject category data can perform
reasonable normalized citation impact studies by combining normalization against
journal with normalization against Essential Science Indicators field. (C) 2010

measures: Empirical applications. Journal of Informetrics, 5 (1), 122-145.
Full Text: 2011\J Inf5, 122.pdf
Abstract: This paper contains the first empirical applications of a novel methodology for
comparing the citation distributions of research units working in the same
homogeneous field. The paper considers a situation in which the world citation
distribution in 22 scientific fields is partitioned into three geographical areas: the U.
S., the European Union (EU), and the rest of the world (RW). Given a critical
citation level (CCL), we suggest using two real valued indicators to describe the
shape of each area’s distribution: a high-and a low-impact measure defined over the
set of articles with citations below or above the CCL. It is found that, when the CCL
is fixed at the 80th percentile of the world citation distribution, the U. S. performs
dramatically better than the EU and the RW according to both indicators in all
scientific fields. This superiority generally increases as we move from the incidence
to the intensity and the citation inequality aspects of the phenomena in question.
Surprisingly, changes observed when the CCL is increased from the 80th to the 95th
percentile are of a relatively small order of magnitude. Finally, it is found that
international co-authorship increases the high-impact and reduces the low-impact
level in the three geographical areas. This is especially the case for the EU and the
RW when they cooperate with the U.S. (C) 2010 Elsevier Ltd. All rights reserved.

Abstract: This paper presents an approach to analyze the thematic evolution of a given
research field. This approach combines performance analysis and science mapping
for detecting and visualizing conceptual subdomains (particular themes or general
thematic areas). It allows us to quantify and visualize the thematic evolution of a
given research field. To do this, co-word analysis is used in a longitudinal framework
in order to detect the different themes treated by the research field across the given
time period. The performance analysis uses different bibliometric measures,
including the h-index, with the purpose of measuring the impact of both the detected
themes and thematic areas. The presented approach includes a visualization method
for showing the thematic evolution of the studied field. Then, as an example, the
thematic evolution of the Fuzzy Sets Theory field is analyzed using the two most
important journals in the topic: Fuzzy Sets and Systems and IEEE Transactions on
Fuzzy Systems. (C) 2010 Elsevier Ltd. All rights reserved.

Abstract: Scientific collaboration and endorsement are well-established research topics
which utilize three kinds of methods: survey/questionnaire, bibliometrics, and
complex network analysis. This paper combines topic modeling and path-finding
algorithms to determine whether productive authors tend to collaborate with or cite
researchers with the same or different interests, and whether highly cited authors tend
to collaborate with or cite each other. Taking information retrieval as a test field, the
results show that productive authors tend to directly coauthor with and closely cite
colleagues sharing the same research interests; they do not generally collaborate
directly with colleagues having different research topics, but instead directly or
indirectly cite them; and highly cited authors do not generally coauthor with each
135
other, but closely cite each other. Published by Elsevier Ltd.

Abstract: The practice of collaboration, and particularly international collaboration, is
becoming ever more widespread in scientific research, and is likewise receiving
greater interest and stimulus from policy-makers. However, the relation between
research performance and degree of internationalization at the level of single
researchers still presents unresolved questions. The present work, through a
bibliometric analysis of the entire Italian university population working in the hard
sciences over the period 2001-2005, seeks to answer some of these questions. The
results show that the researchers with top performance with respect to their national
colleagues are also those who collaborate more abroad, but that the reverse is not
always true. Also, interesting differences emerge at the sectorial level. Finally, the
effect of the nation involved in the international partnership plays a role that should
not be ignored. (C) 2010 Elsevier Ltd. All rights reserved.

Abstract: Accurate computation of h indices or other indicators of research impact
requires access to databases supplying complete and accurate citation information.
The Web of Science (WoS) database is widely used for this purpose and it is
generally deemed error-free. This note describes an inaccuracy that seems to affect
differentially non-English sources and targets in WoS, namely, “phantom citations”
(i.e., papers reported by WoS to cite some article when they actually did not) and
their concentration around particular articles that are thus dubbed “strange attractors”.
The analysis of references in (and citations to) papers in two English sources and two
136
non-English sources reveals that phantom citations and other errors of indexing occur
about twice as often with non-English items. These and other errors of commission
affect about 1% of the cited references in the WoS database, and they may reveal
large-scale problems in the reference matching algorithm in WoS. (C) 2010 Elsevier

Abstract: The three important research domains, nanotechnology, biotechnology and
pharmaceuticals, integratedly breed a promising multidisciplinary domain in the
post-genomic age, which was recently defined by the term “nanobiopharmaceuticals”.
In this paper, we firstly investigate its general development profiles, and then
implement cross-country comparisons in its research performances, with the focus on
the world share, relative research effort, impact and quality of five productive
countries. Furthermore, from the science mapping perspective, we build the co-word
and co-citation networks respectively for detecting its intellectual structure as well as
evolution footprints of intellectual turning points. The growth examinations based on
the datasets from WoS, MEDLINE and BIOSIS Review confirm the exponential
growth of publications and citations in nanobiopharm-research. The cross-country
comparisons show that USA is the leading country, and China is an up-and-coming
contributor. The visual mapping structures by co-occurrence analyses show that
nanobiopharm-research is currently focused on the drug development for improving
biodistribution, bioavailability and pharmacokinetics, and the drug delivery for
improving delivery of existing drugs. Some pivot publications is identified by
CiteSpace, which work as structural holes, research fronts and intellectual bases for
the nanobiopharm-research development in the given time window. (C) 2010

Full Text: 2011\J Inf5, 248.pdf
Abstract: The popular h-index used to measure scientific output can be described in
terms of a pool of evaluated objects (the papers), a quality function on the evaluated
objects (the number of citations received by each paper) and a sentencing line
crossing the origin, whose intersection with the graph of the quality function yields
the index value (in the h-index this is a line with slope 1). Based on this abstraction,
we present a new index, the c-index, in which the evaluated objects are the citations
received by an author, a group of authors, a journal, etc., the quality function of a
citation is the collaboration distance between the authors of the cited and the citing
papers, and the sentencing line can take slopes between 0 and infinity. As a result,
the new index counts only those citations which are significant enough, where
significance is proportional to collaboration distance. Several advantages of the new
c-index with respect to previous proposals are discussed. (C) 2010 Elsevier Ltd. All

Abstract: In December 2003, seventeen years after the first UK research assessment
exercise, Italy started up its first-ever national research evaluation, with the aim to
evaluate, using the peer review method, the excellence of the national research
production. The evaluation involved 20 disciplinary areas, 102 research structures,
18,500 research products and 6661 peer reviewers (1465 from abroad); it had a direct
cost of 3.55 millions Euros and a time length spanning over 18 months. The
introduction of ratings based on ex post quality of output and not on ex ante respect
for parameters and compliance is an important leap forward of the national research
evaluation system toward meritocracy. From the bibliometric perspective, the
national assessment offered the unprecedented opportunity to perform a large-scale
comparison of peer review and bibliometric indicators for an important share of the
Italian research production. The present investigation takes full advantage of this
opportunity to test whether peer review judgements and (article and journal)
bibliometric indicators are independent variables and, in the negative case, to
measure the sign and strength of the association. Outcomes allow us to advocate the
use of bibliometric evaluation, suitably integrated with expert review, for the
forthcoming national assessment exercises, with the goal of shifting from the
assessment of research excellence to the evaluation of average research performance
without significant increase of expenses. (C) 2010 Elsevier Ltd. All rights reserved.

Abstract: This paper attempts to build a classification model according to the research
products created by those institutes and hence to design specific evaluation processes.
Several scientific input/output indicators belonging to 109 research institutes from
the Spanish National Research Council (CSIC) were selected. A multidimensional
approach was proposed to resume these indicators in various components. A
clustering analysis was used to classify the institutes according to their scores with
those components (principal component analysis). Moreover, the validity of the a
priori classification was tested and the most discriminant variables were detected
(linear discriminant analysis). Results show that there are three types of institutes
according to their research outputs: Humanistic, Scientific and Technological. It is
argue that these differences oblige to design more precise assessment exercises
which focus on the particular results of each type of institute. We conclude that this
method permits to build more precise research assessment exercises which consider
the varied nature of the scientific activity. (C) 2011 Elsevier Ltd. All rights reserved.

Abstract: This paper reports on the first documented attempt to investigate the presence
of the superstar (or Matthew) effect in the knowledge management and intellectual

were applied to the publication data obtained from 2175 articles from 11 KM/IC
journals. Based on the findings, it was concluded that the KM/IC discipline
represents a very young, attractive academic field that welcomes contributions from
a variety of academics and practitioners. In their paper acceptance decisions, KM/IC
journal editors are not biased towards a small group of highly productive researchers,
which is a positive sign that the field has been progressing in the right direction. The
discipline is driven more by academics than by practitioners, and the distribution of
articles is more concentrated among a few academic but not practitioner institutions.
It was also observed that the Yule-Simon model and Lotka’s square law may produce
different distributions with respect to institutions. (C) 2011 Elsevier Ltd. All rights

Abstract: This paper presents the first meta-analysis of studies that computed
correlations between the h index and variants of the h index (such as the g index; in
total 37 different variants) that have been proposed and discussed in the literature. A
high correlation between the h index and its variants would indicate that the h index
variants hardly provide added information to the h index. This meta-analysis
included 135 correlation coefficients from 32 studies. The studies were based on a
total sample size of N = 9005; on average, each study had a sample size of n = 257.
The results of a three-level cross-classified mixed-effects meta-analysis show a high
correlation between the h index and its variants: Depending on the model, the mean
correlation coefficient varies between 8 and 9. This means that there is redundancy
between most of the h index variants and the h index. There is a statistically
significant study-to-study variation of the correlation coefficients in the information
they yield. The lowest correlation coefficients with the h index are found for the h
index variants MII and m index. Hence, these h index variants make a non-redundant
contribution to the h index. (C) 2011 Elsevier Ltd. All rights reserved.

Abstract: In 2008, the type of document “proceedings paper” (PP) was assigned in the
WoS database to journal articles which were initially presented at a conference and
later adapted for publication in a journal. Since the use of two different labels
(“article” and “proceedings paper”) might lead to infer differences in their relevance
and/or quality, this paper presents a comparative study of standard journal articles
and PP in journals to explore potential differences between them. The study focuses
on the Library and Information Science field in the Web of Science database and
covers the 1990-2008 period. PP approximately account for 9% of the total number
141
of articles in this field, two-thirds of which are published in monographic issues
devoted to conferences, which tend to be concentrated in specific journals.
Proceedings papers emerge as an heterogeneous set comprising PP in ordinary issues,
similar to standard articles in structure and impact of research; and PP in
monographic issues, which seem to be less comprehensive and tend to receive less
citations. Faster publication of PP in monographic than in ordinary issues may
conceal differences in the review process undergone by either type of paper. The
main implications of these results for authors, bibliometricians, journal editors and
research evaluators are pointed out. (C) 2011 Elsevier Ltd. All rights reserved.

Abstract: This paper proposes an empirical analysis of several scientists based on their

particular, we empirically analyse three recent bibliometric tools to perform

tools are respectively (1) the PY/CY diagram, (2) the publication/citation Ferrers
diagram and triad indicators, and (3) a year-by-year comparison of the scientists’
output (Borda’s ranking). Results of the regularity analysis are then compared with
those obtained under the classical perspective of overall production. The proposed
evaluation tools can be applied to competitive examinations for research
position/promotion, as complementary instruments to the commonly adopted
bibliometric techniques. (C) 2011 Elsevier Ltd. All rights reserved.

Abstract: Based on historical citation data from the ISI Web of Science, this paper
introduces a methodology to automatically calculate and classify the real career
h-index sequences of scientists. Such a classification is based on the
convexity-concavity features of the different temporal segments of h-index
sequences. Five categories are identified, namely convex, concave, S-shaped,
142
IS-shaped and linear. As a case study, the h-index sequences of several Nobel Prize
winners in Medicine, Chemistry and Economics are investigated. Two proposed
factors influencing the growth of the h-index, namely the “freshness” of the h-index
core and changes in the rank positions of papers near the h-index point are studied. It
is found that the h-index core’s “freshness” is particularly relevant to the growth of
the h-index. Moreover, although in general more publications lead to an increase of
the h-index, the key role is played by those papers near the h-index point. (C) 2011

Abstract: The evolution of the Web has promoted a growing interest in social network
analysis, such as community detection. Among many different community detection
approaches, there are two kinds that we want to address: one considers the graph
structure of the network (topology-based community detection approach); the other
one takes the textual information of the network nodes into consideration
(topic-based community detection approach). This paper conducted systematic
analysis of applying a topology-based community detection approach and a
topic-based community detection approach to the coauthorship networks of the
information retrieval area and found that: (1) communities detected by the
topology-based community detection approach tend to contain different topics within
each community; and (2) communities detected by the topic-based community
detection approach tend to contain topologically-diverse sub-communities within
each community. The future community detection approaches should not only
emphasize the relationship between communities and topics, but also consider the
dynamic changes of communities and topics. Published by Elsevier Ltd.

Abstract: We propose a novel yet practical method capturing an individual’s research or

innovation performance by the shape centroids of the h-core and h-tail areas of its
publications or patents. A large number of individuals’ relative performance with
respect to their h-cores and h-tails can be simultaneously positioned and conveniently
observed in two-dimensional coordinate systems. Two approaches are further
proposed to the utilization of the two-dimensional distribution of shape centroids.
The first approach specifically determines, within a group of individuals, those
outperforming or being outperformed by a target individual. The second approach
provides a quick qualitative categorization of the individuals so that the nature of
their performance is revealed. Using patent assignees as an illustrative case, the
approaches are tested with empirical patent assignee data. Crown Copyright (C) 2011

predictions of the power-law equation. Analysis of the former data revealed that: (1)
the progressive nucleation mechanism describes the data better than the power-law
relation, (2) the field of social sciences is saturated much earlier than science and
technology but publication activity in humanities is saturated much later, and (3) that
social sciences have the maximum growth, followed by lower growth in humanities
and the lowest growth in science and technology. The data on journals J(t), papers
N(t) and authors W(t) against publication year Y in malaria research can be described
equally well by equations of the power-law and progressive nucleation mechanism,
and the growth of journals J(t) and articles N(t) is intimately connected with the
growth of authors W(t). (C) 2011 Elsevier Ltd. All rights reserved.

Abstract: As research becomes an ever more globalized activity, there is growing
interest in national and international comparisons of standards and quality in
different countries and regions. A sign for this trend is the increasing interest in
rankings of universities according to their research performance, both inside but also
outside the scientific environment. New methods presented in this paper, enable us to
map centers of excellence around the world using programs that are freely available.
Based on Scopus data, field-specific excellence can be identified and agglomerated
in regions and cities where recently highly cited papers were published. Differences
in performance rates can be visualized on the map using colours and sizes of the
marks. (C) 2011 Elsevier Ltd. All rights reserved.

Abstract: Dependence of citations L(t) at time t on the publication duration t of 10
arbitrarily selected Polish professors is analyzed using equations based on power law
and exponential growth and on progressive nucleation mechanism for overall
crystallization in fixed volume. The former two approaches are well known in the
bibliometric literature, but the last approach is new for the analysis of growth of
citations and other related phenomena. It was found that: (1) power-law relation and
exponential growth are relatively inadequate to analyze the data of all authors due to
large scatter in the L(t) data of various authors, (2) in view of poor fit at low or high
values of t, the exponential growth relation is worse than the power-law relation, and
(3) the progressive nucleation mechanism describes the data reasonably well and
gives information on the processes of sources of citations and the growth of theses
citation sources. (C) 2011 Elsevier Ltd. All rights reserved.

Abstract: Scientometric models, which consider papers in a undifferentiated way, are

definition of a function P(S), for any set of scientific articles S, which reflects global
properties of the citation network associated to S. Such a function, that we propose as
a measure of the impact of scientific papers, is constructed as solution of an iterated
system of Perron-eigenvalue problems. We discuss differences with previously

based on a reliable and representative publication set of 755 papers retrieved from
the Web of Science database using keywords and citation links. In the course of the

study we analyse several aspects of the emergence of this topic, the differentiation of
methodological research, its application within and outside the field and the
dissemination process of information among different disciplines in the sciences and
social sciences. Finally, a cluster analysis of h-related literature is conducted. The
hybrid clustering algorithm results in four clusters, which depict two different
aspects each of basic and applied research related to the h-index and its derivatives.

Abstract: We investigated the occurrence of non-alphanumeric characters in a
randomized subset of over almost 650,000 titles of scientific publications from the
Web of Science database. Additionally, for almost 500,000 of these publications we
correlated occurrence with impact, using the field-normalised citation metric
CPP/FCSm. We compared occurrence and correlation with impact both at in general
and for specific disciplines and took into account the variation within sets by
(non-parametrically) bootstrapping the calculation of impact values. We also
compared use and impact of individual characters in the 30 fields in which
non-alphanumeric characters occur most frequently, by using heatmaps that clustered
and reordered fields and characters. We conclude that the use of some
non-alphanumeric characters, such as the hyphen and colon, is common in most titles
and that not including such characters generally correlates negatively with impact.
Specific disciplines on the other hand, may show either a negative, absent, or
positive correlation. We also found that thematically related science fields use
non-alphanumeric characters in comparable numbers, but that impact associated with
such characters shows a less strong thematic relation. Overall, it appears that authors
cannot influence success of publications by including non-alphanumeric characters in
fields where this is not already commonplace. (C) 2011 Published by Elsevier Ltd.

The analysis is based on bibliometric data from the Italian university system for the

input being considered as a university’s research staff, classified according to
academic rank, and with output considered as the field-standardized impact of the
research product realized by these staff. The analysis is applied to all scientific
disciplines of the so-called hard sciences, and conducted at subfield level, thus at a
greater level of detail than ever before achieved in national-scale research
assessments. (C) 2011 Elsevier Ltd. All rights reserved.

Abstract: With the passage of more time from the original date of publication, the
measure of the impact of scientific works using subsequent citation counts becomes
more accurate. However the measurement of individual and organizational research
productivity should ideally refer to a period with closing date just prior to the
evaluation exercise. Therefore it is necessary to compromise between accuracy and
timeliness. This work attempts to provide an order of magnitude for the error in
measurement that occurs with decreasing the time lapse between date of publication
and citation count. The analysis is conducted by scientific discipline on the basis of

Full Text: 2011\J Inf5, 698.pdf
Abstract: Journal impact factors continue to play an important role in research output
assessment, in spite of the criticisms and debates around them. The impact factor
rankings provided in the Journal Citation Reports (JCR (TM)) database by
Thompson Reuters have enjoyed a position of monopoly for many years. But this has
recently changed with the availability of the Scopus (TM) database and its associated
journal ranking published in the Scimago Journal Rank (SJR) Web page, as the
former provides a citation database with similar inclusion criteria to those used in the
JCR and the latter and openly accessible impact factor-based ranking. The
availability of alternatives to the JCR impact factor listings using a different citation
database raises the question of the extent to which the two rankings can be
considered equally valid for research evaluation purposes. This paper reports the
results of a contrast of both listings in Computer Science-related topics. It attempts to
answer the validity question by comparing the impact factors of journals ranked in
both listings and their relative position. The results show that impact factors for
journals included in both rankings are strongly correlated, with SJR impact factors in
general slightly higher, confirming previous studies related to other disciplines.
Nonetheless, the consideration of tercile and quartile position of journal yields some
divergences for journals appearing in both rankings that need to be accounted for in
research evaluation procedures. (C) 2011 Elsevier Ltd. All rights reserved.

specialized publication records. Journal of Informetrics, 6 (1), 1-10.
Full Text: 2012\J Inf6, 1.pdf
Abstract: Field normalized citation rates are well-established indicators for research
performance from the broadest aggregation levels such as countries, down to
institutes and research teams. When applied to still more specialized publication sets
at the level of individual scientists, also a more accurate delimitation is required of
the reference domain that provides the expectations to which a performance is
compared. This necessity for sharper accuracy challenges standard methodology
based on pre-defined subject categories. This paper proposes a way to define a
reference domain that is more strongly delimited than in standard methodology, by
building it up out of cells of the partition created by the pre-defined subject
categories and their intersections. This partition approach can be applied to different
existing field normalization variants. The resulting reference domain lies between
those generated by standard field normalization and journal normalization. Examples
based on fictive and real publication records illustrate how the potential impact on
results can exceed or be smaller than the effect of other currently debated
normalization variants, depending on the case studied. The proposed Partition-based
Field Normalization is expected to offer advantages in particular at the level of
individual scientists and other very specific publication records, such as publication
output from interdisciplinary research. (C) 2011 Elsevier Ltd. All rights reserved.

Abstract: A number of bibliometric studies point out that citation counts are a function
of many variables besides scientific quality. In this paper our aim is to investigate
these factors that usually impact the number of citation counts, using an extensive
data set from the field of chemistry. The data set contains roughly 2000 manuscripts
that were submitted to the journal Angewandte Chemie International Edition (AC-IE)
150
as short communications, reviewed by external reviewers, and either published in
AC-IE or, if not accepted for publication by AC-IE, published elsewhere. As the
reviewers’ ratings of the importance of the manuscripts’ results are also available to
us, we can examine the extent to which certain factors that previous studies
demonstrated to be generally correlated with citation counts increase the impact of
papers, controlling for the quality of the manuscripts (as measured by reviewers’
ratings of the importance of the findings) in the statistical analysis. As the results
show, besides being associated with quality, citation counts are correlated with the
citation performance of the cited references, the language of the publishing journal,
the chemical subfield, and the reputation of the authors. In this study no statistically
significant correlation was found between citation counts and number of authors. (C)

substantial differences between the journal choices of these elite scientists and the
ERA classification and ranking of journals. Implications from these findings are that
additional cross-classifications should be added for many journals, and there should
be an adjustment to the ranking of several journals relevant to the ERA Field of

Abstract: This article reports a comparative study of five measures that quantify the
degree of research collaboration, including the collaborative index, the degree of

degree centrality. The empirical results showed that these measures all capture the
notion of research collaboration, which is consistent with prior studies. Moreover,
the results showed that degree centrality, the revised collaborative coefficient, and
the degree of collaboration had the highest coefficient estimates on research
productivity, the average JIF, and the average number of citations, respectively.
Overall, this article suggests that the degree of collaboration and the revised
collaborative coefficient are superior measures that can be applied to bibliometric
studies for future researchers. (C) 2011 Elsevier Ltd. All rights reserved.

Abstract: This paper presents an empirical analysis of two different methodologies for
calculating national citation indicators: whole counts and fractionalised counts. The
aim of our study is to investigate the effect on relative citation indicators when
citations to documents are fractionalised among the authoring countries. We have
performed two analyses: a time series analysis of one country and a cross-sectional
analysis of 23 countries. The results show that all countries’ relative citation
indicators are lower when fractionalised counting is used. Further, the difference
between whole and fractionalised counts is generally greatest for the countries with
the highest proportion of internationally co-authored articles. In our view there are
strong arguments in favour of using fractionalised counts to calculate relative citation
indexes at the national level, rather than using whole counts, which is the most
common practice today. (C) 2011 Elsevier Ltd. All rights reserved.

Abstract: A variant of the h-index, named the stochastic h-index, is proposed. This new
index is obtained by adding to the h-index the probability, under a specific stochastic
model, that the h-index will increase by one or more within a given time interval.
The stochastic h-index thus extends the h-index to the real line and has a direct
interpretation as the distance to the next higher index value. We show how the
stochastic h-index can be evaluated and compare it with other variants of the h-index
which purportedly indicate the distance to a higher h-index. (C) 2011 Elsevier Ltd.

Abstract: We show that essentially local dynamics of citation networks bring special
information about the relevance/quality of a paper. Up to some rescaling, they
exhibit universal behavior in citation dynamics: temporal patterns are remarkably
consistent across disciplines, and uncover a prediction method for citations based on
the structure of references only, at publication time. Above-average cited papers
universally focus extensively on their own recent subfield - as such, citation counts
essentially select what may plausibly be considered as the most disciplinary and
normal science; whereas papers which have a peculiar dynamics, such as re-birthing
scientific works - ‘rediscovered classics’ or ‘early birds’ - are comparatively poorly
cited, despite their plausible relevance for the underlying communities. The “rebirth
153
index” that we propose to quantify this phenomenon may be used as a
complementary quality-defining criterion, in addition to final citation counts. (C)

Abstract: Citation numbers are extensively used for assessing the quality of scientific
research. The use of raw citation counts is generally misleading, especially when
applied to cross-disciplinary comparisons, since the average number of citations
received is strongly dependent on the scientific discipline of reference of the paper.
Measuring and eliminating biases in citation patterns is crucial for a fair use of
citation numbers. Several numerical indicators have been introduced with this aim,
but so far a specific statistical test for estimating the fairness of these numerical
indicators has not been developed. Here we present a statistical method aimed at
estimating the effectiveness of numerical indicators in the suppression of citation
biases. The method is simple to implement and can be easily generalized to various
scenarios. As a practical example we test, in a controlled case, the fairness of
fractional citation count, which has been recently proposed as a tool for
cross-discipline comparison. We show that this indicator is not able to remove biases
in citation patterns and performs much worse than the rescaling of citation counts
with average values. (C) 2011 Elsevier Ltd. All rights reserved.

Abstract: Research topics and research communities are not disconnected from each
other: communities and topics are interwoven and co-evolving. Yet, scientometric
evaluations of topics and communities have been conducted independently and
synchronically, with researchers often relying on homogeneous unit of analysis, such
154
as authors, journals, institutions, or topics. Therefore, new methods are warranted
that examine the dynamic relationship between topics and communities. This paper
examines how research topics are mixed and matched in evolving research
communities by using a hybrid approach which integrates both topic identification
and community detection techniques. Using a data set on information retrieval (IR)
publications, two layers of enriched information are constructed and contrasted: one
is the communities detected through the topology of coauthorship network and the
other is the topics of the communities detected through the topic model. We find
evidence to support the assumption that IR communities and topics are interwoven
and co-evolving, and topics can be used to understand the dynamics of community
structures. We recommend the use of the hybrid approach to study the dynamic
interactions of topics and communities. (C) 2011 Elsevier Ltd. All rights reserved.

Abstract: Four La-containing sulfated Zr-pillared clay solid acids with rectorites as
matrix were prepared by utilizing different methods for La introduction and
characterized by nitrogen adsorption, desorption, XRD, NH3-TPD and Py-IR
techniques.The effects of different introduction methods for La on the structure and
acidity of the resulting catalysts were investigated. The experimental results show
that regularity for the layer structure of formed catalysts is significantly improved by
either exchanging Na-rectorite with LaCl3 solution followed by pillaring with Zr
pillaring agent or by utilizing La-Zr bipillaring agent. In addition, the employment of
these two preparation methods leads to a more uniform pore size distribution, a
larger specific surface area and an improvement in the amount and intensity of Lewis
acid.

Abstract: The dissolved organic carbon in natural water was mainly from soluble humic
acid(HA) which had much harms in industrial and drinkable water. As a new
156
adsorbent, the multi-walled carbon nanotubes (MCNTs) were used to remove HA at
different pH value, different MCNTs dosages and different HA initial concentration,
a series of experiments including batch adsorption, adsorption isotherm were carried.
The adsorption kinetics data was fitted with pseudo-second-order rate model, their
linear correlations was above 0.99, and equilibrium adsorption capacity obtained
from fitting curve was 27mg/g, consistent with the experimental results (25.5mg/g).
The adsorption isotherm test was carried at 25ºC-50ºC, the equilibrium adsorption
capacity was 29.7mg/g by Langmuir model, which was similar to the experiment
results. The free energy (ΔG), enthalpy (ΔH) and entropy (ΔS) were obtanined with
Clapeyron-Clausius and Gibbs-Helmholtz equation in the adsorption isotherm, which
all were negative, indicated that HA adsorbed by MCNT was an exothermic process
of entropy reduction. MCNT’s outer surfaces, layer interspace, inner cavity and
aggregated pores became efficient adsorption space for HA. The pi-pi interactions
between HA and MCNT played an important role in the adsorption process.

Abstract: The formation of lead-nitrate complexes in HNO3-water-isopropyl alcohol
solutions was studied by the polarographic method. Successive formation constants
for the first and second complexes in 25, 80 and 90 per cent isopropyl alcohol
solutions were found to be 1·0 (μ = 1·5), 14 (μ = 1·5), 154 (μ = 1·0), respectively.
Using data from the polarographic study, it was possible to correlate the distribution
coefficient of lead with the mole fraction alcohol using the relation
log D = −δF/RT + log {β2(NO3−)2/[1 + β1(NO3−)2]};. The free energy change for the
transfer of the neutral complex from the solution phase to the resin phase, −ΔF,
should vary linearly with the mole fraction alcohol in solution. This was confirmed
by the linear relationship of log D vs. nalcohol and log {β2(NO3−)2/[1 +
β1(NO3−)2]}; vs. nalcohol.

Abstract: The sorption on silica of the complexes of Ag+, Zn2+, Cu2+, Co2+, and Co3+
with ethylenediamine was studied. Using the static method the dependence of the
capacity of the silica on the pH was evaluated and the molar ratio of released acid to
the concentration of sorbed complexes was determined. It was found that over a wide
pH range the amount of released acid is equal to the charge of the complex.

Abstract: The heterogeneous exchange reaction of calcium carbonate in calcium
chloride solution has been studied using 45Ca as a tracer. The results of this study
indicate that the rate is controlled by the surface reaction at the solid-liquid interface.
It is found that the exchange rate increases as CaCl2 concentration decreases for a
fixed mole ratio of the exchange ion on the solid surface and in the solution. The
activation energy is calculated to be 8.45 kcal/mole. The results show that the longer
the solid is immersed in CaCO3 saturated water, the higher the rate constant is
obtained. The rate constant is also affected by the condition of the calcium carbonate
preparation.

Full Text: 1960-80\J Ino Nuc Che34, 47.pdf
Abstract: The isotopic exchange reaction of calcium ion and calcium oxalate has been
studied using45Ca as tracer. The results show that the exchange phenomenon is a
complex one. The rate is controlled by the super-position of a faster interfacial ion
exchange process and a slower particle diffusion process in the solid particle. The
exchange reaction is affected by the condition of preparation of calcium oxalate. The
activation energies of the exchange reaction at interface, and the particle diffusion in
the solid, are calculated to be 9.27 kcal per mole and 7·70 kcal per mole, respectively.
The activation entropy for the interface mass reaction is −19·8 e.u./mole. This
negative value implies that there exists an entropy barrier in the present system. The
results also indicate that the effect of recrystallization can be neglected.

Abstract: The kinetics of heterogeneous isotopic exchange of phosphate between
32
P-labelled dilute orthophosphate solutions and Fe(III) phosphate complexes on the
surfaces of goethite (-FeOOH) crystals in dilute suspension are described by the
Elovich Equation. Concentration-independent rate constants are obtained at 25° for
the pH range 2·6–12. The reference states for the rate constants are defined with
respect to an approximation for the distribution of activation energies for exchange.
Rates of exchange are first order with respect to the concentration of Fe(III)
phosphate surface complexes, show little or no dependence on the concentration of
phosphate in solution, and are subject to acid-base catalysis involving fractional
159
powers of H+ and OH− concentrations with a minimum rate at pH 9·0. The inert
character of Fe(III) phosphate complexes is attributed to the formation of a briding
ligand structure in binuclear complexes on the predominantly-exposed (100) crystal
surfaces. The rate-determining step is postulated to be SN1 dissociation or SN2
bimolecular solvolysis of phosphate from Fe(III) co-ordination, in which the
mechanism of catalysis is related to a hydrogen bonding stabilisation of the transition
state.

Zabel, T.F. (1993), Diffuse sources of pollution by heavy metals. Journal of the
Institution of Water and Environmental Management, 7 (5), 513-520.
Abstract: Significant reductions in the amount of heavy metals released to the aquatic
environment have been achieved by applying strict controls on point source
industrial discharges. Because of these tight controls, diffuse pollution sources have
increased in importance as a contribution to the total load. Diffuse inputs originate
mainly from the use of chemical products. Thus control of these inputs can be
achieved by refraining from or limiting the use of these products or by restricting the
amount of heavy metals permitted in such products. Control of diffuse sources of
heavy metals could be based on a ‘positive approval’ system, permitting only those
uses which do not lead to environmental harm and which could not be replaced by
less harmful alternatives. Assessing the environmental impact of the alternatives will
require the introduction of a ‘cradle to grave’ approach.

incinerator, using computational fluid-dynamics and experimental-data. Journal of
the Institute of Energy, 66 (469), 169-179.
Abstract: As regulations governing the disposal of clinical waste become more stringent,
the use of incineration is increasing. Every year in the UK more than 0.7 Mt of
hospital waste is generated; most of it is infectious, and must be incinerated. This
paper reports on the performance of a newly commissioned high-temperature
incinerator plant with a burning capacity of 12 t/day (4 MW); the technology used is
outlined, and a brief description of the emission-monitoring programme is presented.
The testing included the measurement of CO, CO2, O2 and hydrogen chloride (HCI)
concentrations in the flue gases, total particulates and dioxins/furans. Scrubber liquor,
filter cake and ash were also analysed for heavy metals and unburnt carbon content.
A mathematical model of the finite-difference type (FLUENT) was then employed to
predict the three-dimensional reacting flows (gaseous phase) within the incinerator
geometry. The main objective of this modelling work was to investigate the influence
of the design and operating parameters on the overall performance of the incinerator.
Experimental measurements of gas composition, temperature and velocities were
compared with the model predictions. Modelling results indicated trends correctly,
and were invaluable for the interpretation of the incinerator performance data. As a
162
result of the test data and mathematical modelling of the whole process, suggestions
for design improvements were made.
Three secondary-air injection systems were investigated by means of the CFD model, in
an attempt to obtain optimum combustion conditions that would minimise potential
emissions of toxic pollutants and extend the mean gas residence times. The
modelling work showed that the use of six high-speed secondary air jets firing
towards a common centre in the secondary combustion chamber (after-burner)
produced substantially longer residence times, improved the temperature profile at
the exit, reduced the concentration of toxic pollutants, and raised the combustion
efficiency of the plant.

training for people with autistic spectrum disorders. Journal of Intellectual Disability
Research, 46, 430-443.
Abstract: Background People with autism experience profound and pervasive
difficulties in the social domain. Attempts to teach social behaviours tend to adopt
either a behavioural or a ‘theory of mind’ (ToM) approach. The beneficial aspects
and limitations of both paradigms are summarized before an examination of how
virtual reality technology may offer a way to combine the strengths from both
approaches. Methods This is not an exhaustive review of the literature; rather, the
papers are chosen as representative of the current understanding within each broad
topic. Web of Science ISI, EMBASE and PsycInfo were searched for relevant
articles. Results Behavioural and ToM approaches to social skills training achieve
some success in improving specific skills or understanding. However, the failure to
generalize learned behaviours to novel environments, and the unwieldy nature of
some behavioural methodologies, means that there is a need for a training package
that is easy to administer and successful in promoting learning across contexts.
Conclusions Virtual reality technology may be an ideal tool for allowing participants
to practise behaviours in role-play situations, whilst also providing a safe
environment for rule learning and repetition of tasks. Role-play within virtual
environments could promote the mental simulation of social events, potentially
allowing a greater insight into minds. Practice of behaviours, both within and across
contexts, could also encourage a more flexible approach to social problem solving.
Virtual environments offer a new and exciting perspective on social skills training
for people with autistic spectrum disorders.

effects on challenging behaviour among persons with intellectual disabilities.
Journal of Intellectual Disability Research, 54, 634-649.
Abstract: Background Persons with intellectual disabilities (ID) often show challenging
behaviour. We review distinct interventions that are applied to treat these challenging
behaviours, and analyse intervention effects and moderating variables. Methods A
literature search was conducted using the databases ERIC, PsycINFO, Web of
Science and MEDLINE. A random-effects meta-analysis was carried out,
supplemented with sensitivity, subgroup, meta-regression and publication bias
analyses. Results Eighty potential articles were identified, from which 30 contained
sufficient data to enable statistical meta-analysis. From these 30 studies, 18 described
a biological, 13 a psychotherapeutic and nine a contextual intervention, either applied
alone or combined. The overall standardised mean difference was 0.671 (SD =
0.051). As shown by sensitivity analysis, this summary effect size is robust. Assessed
through subgroup and meta-regression analysis, all tested moderators showed no
statistically significant association with the treatment effects. After applying a funnel
plot-, a fail-safe N-, and Duval’s and Tweedie’s trim and fill-analysis, we conclude
that our meta-analysis does not suffer much from publication bias effects.
Conclusions Several biological, psychotherapeutic and contextual interventions
effectively reduce challenging behaviours among persons with ID.

(2), 99-119.
Abstract: This paper surveys applications of data mining techniques to large text
collections, and illustrates how those techniques can be used to support the
management of science and technology research. Specific issues that arise repeatedly
in the conduct of research management are described, and a textual data mining
architecture that extends a classic paradigm for knowledge discovery in databases is
introduced. That architecture integrates information retrieval from text collections,
information extraction to obtain data from individual texts, data warehousing for the
extracted data, data mining to discover useful patterns in the data, and visualization
of the resulting patterns. At the core of this architecture is a broad view of data
mining-the process of discovering patterns in large collections of data-and that step is
described in some detail. The final section of the paper illustrates how these ideas
can be applied in practice, drawing upon examples from the recently completed first
phase of the textual data mining program at the Office of Naval Research. The paper
concludes by identifying some research directions that offer significant potential for
improving the utility of textual data mining for research management applications.

Abstract: Objectives. That occupational exposure to mercury causes reproductive failure
in dental personnel has been propagated by repeated reference to a single
epidemiological study in Poland, published in 1987. The present paper scrutinizes the
results of this study, and monitors its subsequent citation in the literature.
Method. Articles referring to the study were located in the Science Citation Index. From
references in these papers and through other references, further articles were found.
These papers were reviewed, and their content organized in relation to the way in
which the Polish study was cited.
Result. Most authors referred to the findings in the Polish study without critical
evaluation of the data presented.
Conclusions. Citation of irrelevant or misleading scientific data in the literature raises
unfounded concerns in nonscientific circles and may lead to unwarranted regulations.
It is therefore essential that editors and reviewers of scientific articles also scrutinize
the literature quoted.

activity and risk of cognitive decline: A meta-analysis of prospective studies. J Intern
Med 2011; 269: 107-117. Objective. The relationship between physical activity and
cognitive function is intriguing but controversial. We performed a systematic
meta-analysis of all the available prospective studies that investigated the association
between physical activity and risk of cognitive decline in nondemented subjects.
Methods. We conducted an electronic literature search through MEDLINE,
EMBASE, Google Scholar, Web of Science, The Cochrane Library and
bibliographies of retrieved articles up to January 2010. Studies were included if they
analysed prospectively the association between physical activity and cognitive
decline in nondemented subjects. Results. After the review process, 15 prospective
studies (12 cohorts) were included in the final analysis. These studies included 33
816 nondemented subjects followed for 1-12 years. A total of 3210 patients showed
cognitive decline during the follow-up. The cumulative analysis for all the studies
under a random-effects model showed that subjects who performed a high level of
physical activity were significantly protected (-38%) against cognitive decline during
the follow-up (hazard ratio (HR) 0.62, 95% confidence interval (CI) 0.54-0.70; P <
0.00001). Furthermore, even analysis of low-to-moderate level exercise also showed
a significant protection (-35%) against cognitive impairment (HR 0.65, 95% CI
0.57-0.75; P < 0.00001). Conclusion. This is the first meta-analysis to evaluate the
role of physical activity on cognitive decline amongst nondemented subjects. The
present results suggest a significant and consistent protection for all levels of
physical activity against the occurrence of cognitive decline.

Abstract: The amount and quality of pharmacology and pharmacy research by authors
from China was investigated by comparing published articles from 136 international
journals (1998 - 2007) by authors from mainland China, Hong Kong and Taiwan.
The number of articles, clinical trials, randomized controlled trials, case reports,
impact factors, number of citations and number of articles published in top general
medicine journals were compared. The total number of articles increased
significantly between 1998 and 2007 (from 324 to 2536 per year). In total, there were
12 021 articles: 7576 from mainland China, 3267 from Taiwan and 1178 from Hong
Kong. The accumulated impact factor of the articles from mainland China (16 688.94)
was much higher than for those from Taiwan (8726.92) and Hong Kong (3161.22)
but, among the three regions, Hong Kong had the highest mean impact factor and the
most articles published in top general medicine journals.

Abstract: This qualitative research synthesis reviews interpretive scholarly papers on
multi-disciplinary primary care teams. A bibliographic search was conducted in
electronic databases: Medline, Embase, and the Web of Science Citation Index, and
in the references of retrieved papers. The research consists of a taxonomic analysis of
19 qualitative studies about primary care teams published in peer-reviewed journals
between 2001 and July 2008 in English and French. Nineteen qualitative studies
were synthesized. Two major concerns emerged: (1) strategies for organizational
change toward effective co-operative practice, and (2) dimensions of team
interactions and work relations. The authors conclude that qualitative results suggest
common strategies to improve the development of primary care teams, while
identifying dimensions of team interactions that remain problematic. A fundamental
aspect of team formation appears to be overlooked, i.e., the construction of a
collective identity, which would involve the whole team in a shared ideal of
co-operative practice. The adoption of discourse analysis is suggested as a more
sophisticated qualitative methodology to explore this issue.

Abstract: The aim of this study was to evaluate immunological, hematological and
biochemical parameters in subjects chronically exposed to inhaled formaldehyde (F),
phenol (Ph) and isomers of organic chlorohydrocarbons (Chc) released from
Ksylamit(R). Twenty-two office workers had been exposed for 6 months to vapors of
Ksylamit(R), used for protection of felt plates inside the office building. The
concentration of Ksylamit(R) vapor was measured at the end of the 6-month period
and the level of Ph and F in the air inside the building was 1.3 mg/m3 and 0.8 mg/m3,
respectively. Most of the workers had ailments due to the irritant effect of inhaled
Ksylamit(R), but no remarkable increase in morbidity was found during the 6 months
of exposure and in a 3-year follow-up. Morphological parameters of blood and the
number of natural killer (NK) cells in the group of exposed subjects were within the
range observed in healthy subjects matched for age and sex. The number of
T-lymphocytes and NK cell cytotoxicity were significantly decreased.
Phytohemagglutinin (PHA)- and alloantigen-induced lymphocyte proliferation was
diminished. Some biochemical parameters suggested liver damage, although these
parameters did not correlate with the levels of Ph and methanol excreted in the urine.
Eight subjects with the highest levels of Ph in the urine had decreased erythrocyte
and T-helper lymphocyte numbers, and increased numbers of eosinophils and
monocytes. The results obtained prove that the functions of both the immune and
173
hematopoietic systems could be affected by chronic exposure to these toxic
substances.

Abstract: Background: Cough is a prominent symptom of many allergic diseases and a
major health burden but there is little information available on the current state of
research in this area. Objectives: To analyze long-term developments in cough
research and recent trends. Methods: We searched the Thomson Reuters Web of
Science databases for cough-related items published between 1900 and 2007 and
analyzed the results using scientometric methods and density-equalizing calculations.
Results: We found 12 960 cough-related publications from 132 countries for the
period studied. The most productive country was the United States of America
(USA), followed by the United Kingdom (UK), France, Japan, Canada, and Germany.
These 12 960 published items were cited 165 868 times. The average number of
citations per item increased from 1976 to 1992, with peaks in 1977, 1979, 1981,
1984, 1989 and 1992. Each of these years was followed by a decrease in citation
numbers. Bilateral and multilateral cooperation analysis using the radar chart
technique showed a progressive increase in international co-authorship starting at the
beginning of the 1990s, with a leading role by the USA and the UK. Conclusion: We
detected a marked increased in cough-related research starting in the 1990s. While
the majority of data originates from the US, other countries have taken a leading
position in terms of research quality (number of citations per item).

performance in different medical subspecialties. Journal of Investigative Medicine,
52 (8), 531-536.
Abstract: Background: The simplest variables to quantify on an academic curriculum
vitae are the impact factors (IFs) of journals in which articles have been published.
As a result, these measures are increasingly used as part of academic staff assessment.
The present study tests the hypotheses that IFs exhibit patterns that are consistent
between journals of different specialties and that these IFs reflect the quality of staff
academic performance. Methods: The IFs of a sample of journals from each of four
medical specialties-medicine, oncology, genetics, and public and occupational
health-were downloaded from the Science Citation Index and compared. Overall and
specialty-specific journal IF frequencies were analyzed with respect to distribution
patterns, averages, and skew. Results: Approximately 91% of journal IFs fell within
the 0 to 5 range, with 97% being less than 10. The overall IF distribution featured a
positive skew and a mean of 2.5. Separate analysis of the journal specialty subsets
revealed significant differences in IF means (genetics 3.4 > oncology 3.1 > medicine
2.0 > public health 1.6; p <.006), all of which well exceeded the respective IF
medians. Journals from the general medicine category exhibited both the lowest IF
median (0.7) and the most positively skewed distribution. Conclusion: The
distribution of IFs exhibits degrees of skew, numeric average, and spread that differ
significantly between journal specialty subsets. This suggests that factors other than
random variations underlie much of the IF variation between specialty journals and
reduces the plausibility of a reliable correlation between IFs and the quality of
academic staff performance. It is concluded that a dominant emphasis on IFs in
academic recruitment and promotion may select for long-term faculty characteristics
176
other than academic quality alone.

Abstract: Background: Manuscript authorship and author placement have important
implications for accountability and allocation of credit. The objective of this study
was to assess the relationship between an author’s place in the author list and the
type of contribution reported by that author. This pattern was then used to develop a
method by which author responsibility and accountability can be clarified. Methods:
The published contributions of each author of original research articles with a
minimum of four authors published in the Journal of the American Medical
Association, the British Medical Journal, The Lancet, and the Canadian Medical
Association Journal in a 3-year period after author contribution forms were required
were coded into 1 of eleven contribution categories. The contributions were grouped
according to first, second, middle, and last author and compared by position. Results:
For most categories of contribution, the levels of participation were highest for first
authors, followed by last and then second authors. Middle authors had lower levels
particularly in conception, drafts of the manuscript, supervision, and being a
guarantor. Conclusions: Current patterns of author order and contribution suggest a
consistent theme. Based on the results, a proposal is put forth by which author
accountability is clarified. In this proposal, authors are classified as either “primary,”
“contributing,” or “senior or supervisory,” each with specified contributions. More
than one author may be classified into each author category.

Abstract: The adsorption of Triton X-100 in aqueous solution on the granite sand has
been investigated to evaluate its ability as an adsorbent. Various parameters such as
agitation time, adsorbent dose, adsorbent size, initial concentration of adsorbate, pH,
temperature, and effect of interference ions were studied on the laboratory scale to
establish optimum conditions for the removal of TX-100 from the effluents of
different industries. Isotherm data were analyzed for possible agreement with the
Langmuir and Frendlich adsorption isotherm equations. The first order rate equation
by Lagergren was tested on the kinetic data. The rate of adsorption was conformed a
pseudo first order kinetics with good correlation coefficient. The value of activation
energy of sorption (Ea) was obtained as 44.6 kJ mol-1. Results showed that granite
sand exhibit reasonably good surfactant removals for nonionic types. The possible
role of the adsorbent in a chromatographic column was also worked out.

Abstract: In this study the ability of Cercis siliquastrum L. leaves for the adsorption of
Pb(II), Cu(II) and Ni(II) ions were studied. The effects of different parameters such
as contact time of biosorbent and sorbents, pH of metal solution, and initial metal ion
concentration on the biosorption were investigated. The maximum sorption of all
178
metals were carried out in pH4. Increasing the initial metal concentration in lower
values caused a steep growth in biosorption, which was not observed in higher values.
In the optimum sorption condition, the affinity of the leaves to metal ions was in the
order of Pb(II)>Cu(II)>Ni(II). The biosorption of the metal ions were studied by
Langmuir and Freundlich adsorption isotherm models. It was observed that the data
were fitted very well to Langmuir adsorpotion isotherm model. According to the
obtained correlation coefficient values, Freundlich model could predict Pb(II) and
Cu(II) adsorption adequately but it was not suitable for Ni(II) sorption. Experimental
data were exploited for kinetic evaluations related to the sorption process. According
to our results, second-order kinetic provided a good description of biosorption for the
tested metals with regression correlation coefficients more than 0.9998 for all the
sorbate-sorbent systems.

Abstract: The anion of hippuric acid, hippurate (A(-)), as an organic guest was
intercalated into the interlayers of anionic clay, Zn/Al hydrotalcite-like or layered
double hydroxides (LDH) host by direct co-precipitation method from aqueous
solution for the formation of new nanohybrid compounds, Zn/Al-hippurate
nanohybrids (ZAHs). Various Zn/Al molar ratios (R) = 3-5 and concentrations of HA
(0.06-0.15 M) were used for the synthesis. ZAHs synthesized, using 0.15 M HA, was
found to give well-ordered layered nanohybrid materials with an increase of the basal
spacing to 19.6-21.0 angstrom compared to 8.8-9.0 angstrom in the LDHs. The
increase in the basal spacing is due to the insertion of A(-) organic moiety into the
LDH interlayers. Formation of the host-guest type of material was confirmed by
XRD, FTIR, TGA/DTG and compositional analysis. The release of the intercalated
guest was found to be tunable in a controlled manner by Zn/Al molar ratio and is
governed by pseudo-second order kinetics. Thus, by varying the experimental
conditions, the release property of the guest anion can be tailored as required.

Various physico-chemical parameters such as pH, initial metal ion concentration,
adsorbent dosage and contact time were studied. The optimum solution pH for the
maximum adsorption of Pb(II) was found to be 4. Kinetic data were best described
by pseudo-second-order model. The adsorption process followed both Langmuir and
Freundlich adsorption isotherms at 30°C. Thermodynamic studies indicated that the
adsorption was spontaneous and endothermic in nature. Desorption studies were
carried out by batch and column operations and it was found that 97% Pb(II) could
be recovered by the column process using 0.1 M HCl as eluent.

Abstract: Due to the widespread use of ground water as a supply of drinking water in
the United States. predicting the effect that nonpoint sources of contamination have
on the quality of nearby ground-water supplies is an important element in ensuring
that public health standards are met. A variety of methods have been developed to
simulate this phenomenon. but most assume that the soil system can be simulated as
a homogeneous environment, which in many cases is not true. Thus. a probabiiistic
modeling procedure is developed that simulates the average movement of
contaminants from nonpoint sources of contamination toward an underlying aquifer’s
water table through a heterogeneous soil environment. The proposed modeling
procedure is applied to a hypothetical nonpoint-source contamination problem, and
the results are compared to those of a conventional deterministic contaminant
transport model. The results of this application demonstrate that the proposed
procedure provides superior simulation results as compared to the deterministic
model, which emphasizes the need to account for heterogeneous soil conditions
181
found in natural environments when simulating nonpoint-source contamination
problems.

Abstract: Critics assert that globalization is detrimental to the environment because it
encourages location of polluting industries in countries with low environmental
regulations. We suggest that globalization might also have positive environmental
effects because global ties increase self-regulation pressures on firms in
low-regulation countries. Using survey data from firms in China we find that
multinational ownership, multinational customers, and exports to developed
countries increase self-regulation of environmental performance.

Abstract: The method based on the preservation rule (FPM) is simple and accurate
compared with FEM. This paper discusses FPM using a pseudo second order
hexahedron element. From the viewpoint of primary and adjoining points in the
partial area of the element, a pseudo order element is introduced. The nature of the
local matrix derived from this element is similar to the local matrix of the first order
element. For numerical results of 3D-electric field analysis, it is clear that errors of
FPM using this element are smaller than errors of FPM and FEM using normal
second order and first order elements.

Abstract: Soybean dietary fiber consists of many kinds of polysaccharides which have
different physiological effects on human, and its physiological function may be
changed by heating. In this paper, the composition of polysaccharides in cell wall
and its changes by heating were described. High yield of crude polysaccharides was
observed in roasted soybean, suggesting that high molecular weight compounds were
produced by heating. On the other hand, as an increase of soluble hemicellulose and
a decrease of insoluble hemicellulose were observed, low molecular weight
compounds may be produced by heating. and also we found some differences in
ion-adsorbing ability between raw and roasted soybean. Adsorption ability of
aluminium ion by raw soybean soluble dietary fiber (SDF) was most remarkable.
Adsorption of aluminium by pectic substance-1 and 2 (hot water extract and 0.5%
ammonium oxalate extract) and hemicellulose-1 (1 N-sodium hydroxide extract)
isolated from peeled soybean was observed. But pectic substance-1 and 2 isolated
from soybean peel had lower adsorption ability than peeled soybean. Ail of those
adsorption abilities were decreased by heating. Hemicellulose-2 (4 N-potassium
hydroxide extract) and cellulose isolated from soybean had almost no adsorption
ability.

(10 samples), the natural water samples (21 samples) and the natural mineral water
samples (21 samples). The mineral water of No. 51 contained 3.12 ng/ml of Se (the
maximum), and the natural water sample of No. 16 and the natural mineral water
sample of No. 26 contained 0.03 ng/ml of Se (the minimum). The Se concentration in

Abstract: Purpose - The purpose of this study is to conduct a scientometric analysis of
the body of literature contained in 11 major knowledge management and intellectual
capital (KM/IC) peer-reviewed journals. Design/methodology/approach - A total of
2,175 articles published in 11 major KM/IC peer-reviewed journals were carefully
reviewed and subjected to scientometric data analysis techniques. Findings - A
number of research questions pertaining to country institutional and individual
productivity co-operation patterns, publication frequency, and favourite inquiry
methods were proposed and answered. Based on the findings, many implications
emerged that improve one’s understanding of the identity of KM/IC as a distinct
scientific field. Research limitations/implications - The pool of KM/IC journals
examined did not represent all available publication outlets, given that at least 20
peer-reviewed journals exist in the KM/IC field. There are also KM/IC papers
published in other non-KM/IC specific journals. However, the 11 journals that were
selected for the study have been evaluated by Bontis and Serenko as the top
publications in the KM/IC area. Practical implications - Practitioners have played a
significant role in developing the KM/IC field. However, their contributions have
been decreasing. There is still very much a need for qualitative descriptions and case
studies. It is critically important that practitioners consider collaborating with
academics for richer research projects. Originality/value - This is the most
comprehensive scientometric analysis of the KM/IC field ever conducted.

Abstract: The reaction of phenylhydrazine with bromine in sulfuric acid solution has
been studied kinetically. The pseudo-second-order rate constant is approximately
inversely proportional to hydrogen-ion concentration when the concentration of
sulfuric acid is lower than 1 M. arom the study of the effect of potassium bromide
concentration on the rate constant, it is concluded that both neutral bromine and
tribromide ion participate in the reaction, the rate constants in 0.01M H2SO4 being
5×105M-1.sec-1 and 0. 7×105M-1.sec-1, respectively at 20°C. The pseudo-second-order
rate constant of 2.4-dinitrophenylhydrazine-bromine reaction is independent of
hydrogen ion concentration. From the KBr addition experiment, the rate constants for
Br2 and Br3- were obtained as 1.2×105M-1.sec-1 and 2.0×104M-1.sec-1, respectively.

the conflict of interest and plagiarism for professors and falsification and fabrication
for graduate students. Average knowledge on the research ethics was 75.4 points for
professors and 61.6 points for students based on the 100 points. Conclusion:
Educational needs of research ethics among nursing professors and students in the
postgraduate course was high. We recommend both basic and advanced research
ethics educational programs for the nursing researchers. The basic course should be
at least 6 hr and include various cases and something to discuss.

Abstract: Purpose: This study was done to explore the knowledge structure of Korean
Nursing Science. Methods: The main variables were key words from the research
papers that were presented in the Journal of Korean Academy of Nursing and
journals of the seven branches of the Korean Academy of Nursing. English titles and
abstracts of the papers (n=5,936) published from 1995 through 2009 were included.
Noun phrases were extracted from the corpora using an in-house program (BIKE
Text Analyzer), and their co-occurrence networks were generated via a cosine
similarity measure, and then the networks were analyzed and visualized using Pajek,
a Social Network Analysis program. Results: With the hub and authority measures,
the most important research topics in Korean Nursing Science were identified.
Newly emerging topics by three-year period units were observed as research trends.
Conclusion: This study provides a systematic overview on the knowledge structure
of Korean Nursing Science. The Social Network Analysis for this study will be
useful for identifying the knowledge structure in Nursing Science.

(KAMJE) and the current status of KoreaMed and KoreaMed Synapse. Journal of
the Korean Medical Association, 53 (8), 653-658.
Abstract: The Korean Association of Medical Journal Editors (KAMJE) was founded in
1996. Among the 51 journals which participated in the founding of KAMJE, only 5
were listed in PubMed at the time, and none in Science Citation Index (SCI). In order
to improve the quality of Korean medical journals, KAMJE established regular and
systematic evaluation of medical journals, and has held academies for journal editors
and education programs for manuscript editors. KAMJE has also focused on the
database of Korean medical journals. KoreaMed, which provides access to articles
published in Korean medical journals; KoMCl, which analyzes and provides citation
data; and KoreaMed synapse, a digital archive and reference-linking platform. All of
those are products of the efforts of KAMJE. By publishing “Good Publication
Practice Guidelines for Medical Journals”, KAMJE also has been focused on
research and publication ethics. KAMJE has played an active part in establishing the
Asia Pacific Association of Medical Journal Editors (APAME) and West Pacific
Regional Index Medicus (WPRIM). Today, KAMJE, now composed of 188 journals
covering medicine, nursing, dentistry, veterinary medicine, and nutrition, has 14 and
23 journals listed in PubMed and SCI, respectively. These achievements of KAMJE,
attributable to the unrelenting efforts of Korean medical journal editors and editors,
may be helpful in further improving the status of Korean medical journals.

Abstract: Plagiarism, the use of text and ideas from published works without proper
permission or citation, is difficult to detect since the whole text should be searched
and compared to literature databases. Nevertheless, this process has become simpler
with the advent of web-based technologies and more powerful search tools. Recently,
a case of plagiarism was detected in an invited manuscript submitted to the Journal
of the Korean Medical Association. In the withdrawn manuscript, there were figures
and figure legends copied from other papers with neither permission nor citation.
Only the citation is enough to use content, figures, or tables from other papers when
the original journal is open access with Creative Commons License. Otherwise, to
use such data, it is essential to obtain permission from that paper’s journal publisher.
If plagiarism is detected after publication, the author will face harsh disciplinary
action before the office of research integrity in his or her institute. Also, the paper
may be retracted by the editor. This is the first time that Editorial Board has detected
plagiarism before publication. Screening for plagiarism and other ethical violations
will continue so that we can pursue the status of the representative journal of Korean
physicians and develop a positive reputation for Korean science internationally by
maintaining the utmost quality and integrity in our publications.

Abstract: An accidental spill of phenol (100%) into the Nakdong river with subsequent
contamination of the tap water for about two million consumers in Teagu city of
Korea occurred in March 1991. A historical cohort study of 6, 913 individuals was
undertaken to determine association with illness. Population subjects were divided
into two groups of exposed and unexposed. Exposed subjects were reported to have
significantly more phenol associated symptoms than those in a nearby unexposed
area (39.6% vs. 9.4%, p < 0.01). Especially, in the related symptoms, highly
significant differences were noted in the number of subjects reporting gastrointestinal
illness such as nausea, vomiting, diarrhea, or abdominal pain. During the accident,
study subjects who experienced peculiar taste or odor in the tap water were
significantly more in the exposed areas (92% vs. 34.3%).

Abstract: In order to investigate the extent and growth of SCI publication activity of
Korean medicine, DIALOG’s SCISearch database was searched and the number of
SCI Korean medical papers in each medical specialty was measured by publication
year and by document type for 1996 and 1997. The percentage contribution of
Korean medical papers to SCI database and the SCI publication productivity ratio
were analyzed for each of 57 medical specialties. The data obtained in this study was
compared with the data representing the 1980s and the data for the first half of the
197
1990s. The absolute productivity of SCI Korean medical papers as measured by the
number of SCI Korean papers has increased about ten times from 306 papers in 1990
to 3, 261 papers in 1997. More than 15% of SCI Korean publication output has
resulted from six Korean medical journals indexed in SCI from 1995. The relative
productivity of SCI Korean medical papers as measured by the percentage
contribution from Korea to SCI and by its corresponding productivity ratio is not as
impressive as the absolute productivity and its growth rate. It has increased three
times from 0.245% to 0.642% during the same period. The relative productivity of
SCI Korean medical publication output is not as great as the SCI Korean publication
output of all sciences combined (1.02%).

Abstract: To identify where the quality research activity has been and is carried out in
Korea, and to examine to what extents Korean medical colleges play leading roles in
the production of international research papers, we investigated the publication
productivity of Korean medical colleges and their medical departments as measured
by the number of papers published in foreign journals indexed in MEDLINE. The
12-year period from 1988 to 1999 is covered. A total of 4, 881 papers is published in
MEDLINE foreign journals by the researchers in Korean medical colleges during the
period. The production of MEDLINE papers are concentrated in a few universities.
More than 60% of MEDLINE foreign journal papers is published by top five
universities-25% by Seoul National University, and 15% by Yonsei University. The
newly established medical colleges at the University of Ulsan and Sungkyunkwan
University produced outstanding numbers of papers in less than ten years. Radiology
has led the internationalization of Korean medical papers. It was the most productive
specialty identified in this study. The productivity of Internal medicine is on the rise
from the mid-1990s, and the field began to produce the most number of papers since
then.

evaluating trends in research funding, and the present status of research funding by
the Korea Science and Engineering Foundation (KOSEF). This study analyzed
statistics from KOSEF from 1978 to 2003 to examine support for research. In
medical science field, group-based programs receive more funding than do
individual-based programs. The proportion of research funds allocated to the medical
sciences has increased markedly each year. Researchers in the medical sciences have
submitted more articles to Science Citation Index (SCI) journals than to non-SCI
journals, relative to other fields. Researchers supported by the Mission-Oriented
Basic Grants program have published the majority of these papers, followed by those
supported by the Programs for Leading Scientists, Regional Scientists, Leading
Women Scientists, Young Scientists, and Promising Women Scientists, in that order.
Funding by KOSEF reflects: many decades of government support for research and
development, the development and maintenance of necessary infrastructure, and the
education and training of medical scientists.

Full Text: J Lab Cli Med130, 51.pdf
Abstract: The question of the extent of lead mobilization from the maternal skeleton
during pregnancy and lactation is one of the most outstanding problems of lead
toxicity. We have undertaken a longitudinal cohort study in an urban environment of
European female immigrants of child-bearing age (18 to 35 years) to Australia whose
skeletal lead isotopic composition has been determined to be different from that in
their current environment. The cohort was to consist of 100 immigrants anticipated to
provide 20 pregnant subjects who would be compared with two groups of control
subjects: a matched immigrant nonpregnant control group and second-generation
Australian pregnant control subjects. Pregnant subjects also serve as their own
controls for a comparison of changes during gestation with those before conception.
High-precision lead isotopic compositions and lead concentrations are measured in
maternal blood and urine prenatally, monthly during gestation, and post-natally for 6
months; they are also measured in infant blood and urine for 6 months;
environmental measures are sampled quarterly for 6-day duplicate diet, house dust
and water, and urban air and gasoline. Because of continuing public health concerns
about lead exposure; interim findings from this cohort are being reported. To date
200
there have been 13 conceptions in immigrant subjects, with 7 births, in addition to 3
conceptions in the Australian control group, with 2 births. PbBs have been generally
low, with a geometric mean of 3.0 µg/dl, and have ranged from 1.9 to 20 µg/dl.
Increases in PbB of similar to 20% during pregnancy have been detectable even in
subjects with low blood lead levels, The skeletal contribution to blood lead level,
based on isotopic measurements, has exhibited a mean increase (and standard
deviation) of 31%±19% with a range from 9% to 65%. Earlier studies that used lead
concentrations only have suggested that blood lead levels increased only during the
second half of pregnancy. This increase in blood lead levels has also been observed
in the present study. However, in two subjects the increases in total blood lead were
also detected in the first 2 months of pregnancy. Changes in isotopic composition
and blood lead during gestation for Australian pregnant controls were negligible. The
ratio of cord/maternal blood lead levels varied from 0.54 to 1.05, and the ratio for the
isotopic composition was 0.993 to 1.002. Results of this study confirm that lead is
mobilized from skeletal stores at an accelerated rate during pregnancy and is
transferred to the fetus. These results also show that mobilization from longterm
stores (i.e., bone) contributes significantly to blood lead levels during pregnancy.
Furthermore, exposure of the fetus to lead during pregnancy has implications for
interpretations of neurobehavioral disorders attributed to only postnatal exposure.
Even after 800 days of residence in Australia, the contribution of European skeletal
lead to blood lead in nonpregnant subjects can be on the order of 50%, but the
current PbB may give no indication of the former high skeletal lead burden.

Abstract: Bibliometric analysis is used to assess the “impact” of scientific journals. The
commonest method of evaluation is impact factor. The aim of this study was to
analyse the citation data for otorhinolaryngology journals of the years 1994 to 1998.
Data on the total number of citations and impact factor of journals was obtained from
the CD-ROM editions 1994-98 of the Journal Citation Reports and “Web of Science”
database. The adjusted impact factor and five-year impact factor has been calculated.
Fifteen otorhinolaryngology journals have been identified and ranked according to
the impact factor. Head and Neck has the highest adjusted impact factor. Archives of
Otolaryngology - Head and Neck Surgery has the highest five-year impact factor.
There is considerable variation in the ranking of journals calculated by the five-year
impact factor. Impact factors of otolaryngology journals can help to direct readers to
those journals that have a track record of publishing data that are frequently cited.
Although there are several limitations to the use of citation data to rank journals, the
authors recommend the use of the five-year period for calculation of the impact
factor for ranking of otolaryngology journals.

Abstract: The Science Citation Index (SCI) was introduced primarily as a method of
information retrieval but has also been used an objective measure of the quality of an
article. Citation classics have been described as papers that have been cited 100 times
or more. The aim of this study was to identify the articles published during the 20th
century in otolaryngology-head and neck surgery journals that have achieved classic
citation status and to present an analysis of this data. Using a database provided by
the Institute of Scientific Information (Philadelphia, PA), an assessment was
performed of all articles cited 100 or more times in one of the 28 clinical
otolaryngology-head and neck journals indexed by the annual Journal Citation
Reports. The data were based on citation counts using the 1900 through 1999
Science Citation Index. Institutions located in 10 different countries produced 80
noteworthy articles. The most-cited paper achieved a citation score of 406 and there
were 11 articles cited on more than 200 occasions. All of the articles were published
in eight journals. The earliest identified publication was in 1933 and the most recent
was published in 1993. Twenty authors were involved in two articles and four
authors were associated with three classic citations. This paper confirms that
analysing citation classics reveals a partial insight into advances and historical
developments in the specialty during the last century.

for time since publication, journal, and subject area. To summarize a few of our
results: citations per year peak at 4 years after publication, and an article receives
half of its expected total lifetime citations after 4.6 years; appearing first in an issue
is a significant advantage; international law articles receive fewer citations;
jurisprudence articles are cited more often; articles by young, female, or minority
authors are more heavily cited. Articles with shorter titles, fewer footnotes per page,
and without equations have significantly more citations than other articles. Total
citations generally increase with an article’s length, but citations per published page
peak at 53 pages.

Abstract: This paper uses judicial citation practice to investigate the determinants of
judicial influence in the High Court of Australia. First, we construct measures of
influence based on the number of times a judge is cited by name in a sample of High
Court decisions. The raw citation counts are adjusted to exclude self-citations,
depreciation of legal capital, and variations in terms of period in office. Second, our
measures of influence are regressed on a series of explanatory variables including
age on appointment, appointing government, prior experience, and whether the judge
served as chief justice, for each of the 35 retired judges of the High Court. They
suggest that younger appointees with prior judicial experience exert more influence
per year on the bench. Our results also suggest that conservative appointees exert
more influence than Labor appointees and judges who have served as chief justice
exert more influence than puisne judges.

Abstract: The evolution of the name Information Science (IS) is traced from the
beginnings of “Library economy” up to the emergence of “Informatics”. The
terminology of 39 definitions of IS is compared in order to find the common
concepts of this science and its central topic of investiga tion. The comparison shows
that no consensus exists among the practitioners of IS about what it is or should do.
The concept “information” has also been variously defined for the purposes of IS,
but no generally acceptable definition has been formulated so far. The discipline
called IS has not yet attained the status of a true science, lacking an agreed-upon
central topic of investigation and an unambiguous terminology (as well as other
attributes of a science). The name Informatics, which is already in wide use in other
countries, should possibly be adopted for the discipline that might yet evolve into a
true science.

Abstract: Published studies concerning the characteristics of subject literatures reveal
211
that there is no eommon basis for determining what constitutes the literature of a
subject. Although con siderable knowledge exists on the bibliometric and
documentation characteristics of many subjects, library schools continue to teach
essentially basic reference sources in large groesps of subject areas. Four criteria for
determining the scope of subject literatures are stiggested and a Curriculum for the
Literature of Geography is proposed as example of how education for librarianship
must reflect both established and controversial knowledge.

Abstract: Reports results of a questionnaire survey of UK academic libraries to
determine the level of use of online public access catalogues (OPACs) and the
development of inhouse subject indexes. Seventy-five respondents reported having
commercial systems and seven reported inhouse systems. Data includes: named
systems in use and numbers of libraries using each system; percentages of
bibliographic records in machine-readable format; types of materials; and record
formats (UKMARC, LC MARC etc). Reports the most common access points for
searching the OPACs (author, keyword), methods of generating terms to be used for
subject searching, subject heading sources (LCSH, MeSH, PRECIS) and
classification schemes (Dewey, UDC). Results show that all universities and
polytechnics now have OPACs and only the smaller colleges do not. OPACs are
moving towards comprehensive coverage of academic library stocks with the MARC
record the most popular format. The three main subject access strategies involve:
Library of Congress Subject Headings, inhouse strategies, and strategies not based on
controlled terminology. Draws heavily on the results of an earlier survey by Fran
Slack (1988) Vine, (72) (November), 8-15.

Abstract: Points to the way in which computer scientists and librarians working with the
World Wide Web are turning to traditional library and information science
techniques, such as cataloguing and classification, to bring order to the chaos of the
Web. Explores cataloguing opportunities offered by the ephemeral nature of
materials on the Web and examines several of the latter’s unique characteristics.
Suggests the coupling of automated filtering and measuring to the Web record
cataloguing process, with particular reference to the ephemeral nature of Web
documents and the ability to measure Uniform Resource Locator (URL) and Web
document characteristics and migrate them to catalogue records using automated
procedures. Reports results of an ongoing longitudinal study of 361 randomly
selected Web pages and their Web sites, the data being collected weekly using the
Flashsite 1.01 software package. Four basic approaches to ordering; information on
the Web were studied: postcoordinate keyword and full-text indexes; application of
both precoordinate and postcoordinate filters or identifiers to the native document by
either authors or indexers; use of thesauri and other classification schemes; and
bibliometric techniques employing mapping of hypertext links and other citation
systems. Concludes that off-the-shelf technology exists that allows the monitoring of
Web sites and Web pages to ‘measure’ Web page and Web site characteristics, to
process quantified changes, and to write those changes to bibliographic records.
Capturing semantic or meaningful change is more complex, but these can be
approximated using existing software.

Librarianship and Information Science, 34 (3), 171-174.
Full Text: J\J Lib Inf Sci34, 171.pdf
Abstract: Reviews the work carried out and the legacy left by S. C. Bradford in the field
of documentation, in the context of the debate throughout the first half of the
twentieth century regarding the nature of documentation and its relationship with
librarianship. The emergence of the field of special librarianship is attributed both to
his ideas and the publication of his seminal book Documentation in 1948, the year of
214
his death. The main themes of Bradford’s work, summarized as a series of essays in
‘Documentation’, were: the need for a UK national central library for science and
technology; classification; and abstracting services. The influence of his ideas on the
future of library and information science, particularly those which resulted from his
work for the Library of the Science Museum, London, are discussed. Bradford’s
advocacy of the UDC (Universal Decimal Classification) for the retrieval of patent
information tend to be dismissed but may be shown to have led him to a study of
abstracting services and the publication patterns governing disciplines. This led to his
formulation of what is now known as Bradford’s law of scattering, Bradford’s main
claim to fame. Discussion of Bradford’s hypothesis has proliferated greatly in the
years since Documentation was published, in particular the way in which Bradford
described his law in two ways: verbally; and graphically. The subsequent work that
has been undertaken to rationalize Bradford’s two formulations has yielded
considerable insights into the functioning of publications and the flow of information
involved in disciplines. Further work has been undertaken extensively in the past 50
years to study the relationship between Bradford’s law and other statistical
relationships of interest to information scientists; notably Zipf’s law. The fact that
Bradford’s law continues to be used in its traditional role of analyzing periodical
article scatter has meant that Documentation continues to be cited.

Full Text: 2003\J Lib Inf Sci35, 115.pdf
Abstract: Since its publication in 1963, Derek Price’s Little science, big science (LSBS)
has achieved ‘citation classic’ status. Examination of the genesis of LSBS and the
state of the discipline of the history of science in the UK and the USA in the late
1950s demonstrates that Price’s ideas were formulated during a pivotal period in the
development of socio-historical studies of science. Price’s talent for innovation and
synthesis at an unsettled but highly charged time, and his appreciation of the
pioneering work in science studies of the crystallographer J.D. Bernal, are reflected
in the uniquely profound and wide-ranging respects in which LSBS has contributed
to the development of scientometric and sociological theory.

Abstract: Based on the data of 6,015 journals collected in the Journal Citation Reports
(JCR) the author investigates the characteristics of 5-Year Impact Factor (IF5) with
the method of statistical study. Results show that as a representative average
indicator in journal evaluation, IF5 can reflect the high peak of citation of most
journals; in addition, the distribution of IF5 follows Bradford’s Law. A rank
correlation between IF5 and IF is found, but there are also significant differences.
Their evaluation results are consistent relatively in top- and bottom-level journals,
but there are differences in moderate-level journals. At last, the author presents two
new indicators IFa and IFb. The former can measure the differences between IF5 and
IF and the latter can integrate their evaluation information. 2 figs. 7 tabs. 12 refs.

Abstract: The separation of alkali; alkaline earth, and ammonium cations in several
samples of water was achieved by capillary electrophoresis with indirect UV
detection. A solution of imidazole (10-2, pH 4.5) was used as buffer to resolve a
mixture of six cations (K+, Na+, Ca2+, Ba2+, Li+ and Mg2+) by capillary
electrophoresis at 214 nm in less than 10 min. The addition of potassium cation to
the running buffer has an influence on the resolution of Ca2+/Na+ and Na+/Mg2+
peaks. A linear relationship between the corrected peak area and concentration was
obtained in the 1-10 ppm range for these cations using a hydrodynamic injector. This
electrophoretic system permitted the separation of these inorganic cations at a 50
ppb-level concentration with an hydrodynamic injection, thus making it ossible to

At pH 4.5, potassium and ammonium unfortunately have identical ionic mobilities
causing them to omigrate in an imidazole buffer. Using an alkaline solution of
benzylamine (10-2, pH 9) as arrier electrolyte, their separation can be successfully
achieved with excellent resolution at 204 nm.
The analyses of tap water and several mineral waters have been achieved by capillary
electrophoresis.

Abstract: The separation of anions was performed by capillary zone electrophoresis
with indirect UV detection. Optimum conditions for the separation of 12 anions,
including the concentration of electroosmotic flow modifier, the concentration of the

for the determination of anions in different water samples. The relative standard

Abstract: A suitable indirect photometry chromatographic system for the separation and
detection of common inorganic and organic anions was made by dynamically coating
an octadecyl-bonded silica column with cetyltrimethylammonium ions and using
potassium chromate as the eluent. The effect of chromate ion concentration on the
capacity factor indicates an ion-exchange mechanism. The detection limit of the
anions F-, Cl-, NO2-, Br-, and NO3-, corresponding to a signal-to-noise ratio of 3, were
0.29, 0.55, 0.72, 0.83 and 0.97 ppm, respectively. A linear response was observed
between peak heights and injection volume of a solution with 1.19 ppm F-, 2.22 ppm
Cl-, 2.88 ppm NO2-, 4.99 ppm Br-and 3.88 ppm NO3-. This can further lower the
detection limit of the anions by about 9 fold when a volume of 175 µL is injected.
This system has been applied to the trace analysis of NO3-in tap water. A
concentration of 1.97±0.10 ppm NO3-was detected. This system was also found
applicable for the separation of organic acids (formate, acetate, propionate and
butyrate) and may also be used for the separation of a mixture of organic and

inorganic anions.

1383-1403.
Abstract: Ion Chromatography is a well-established analytical technique for the
simultaneous determination of ions. This paper focuses on the analytical
determination of eight inorganic anions: fluoride, hydrogen carbonate, chloride,
nitrite, bromide, nitrate, hydrogen phosphate and sulphate, using conductometric
detection. The separation of the cited anions was achieved on a low capacity anion
exchange column Hamilton PRP-X100 100×4.1 mm, 10 µm, with a mobile phase
consisted of 2.5 mM p-hydroxybezoic acid and 2.0 mM sodium benzoate at a pH 9.0
adjusted with 1N NaOH and 8% CH3OH as organic modifier, at a flow rate 0.7
ml/min. For the quantitative determination bromide was used as internal standard at a
concentration of 7.8 mg/l. A rectilinear relationship was observed up to 40 mg/l for
all ions except for carbonate that was up to 30 mg/l. The detection limits (SIN = 3)
were 100 µg/l for carbonate and 50 µg/l for the rest of the cited anions, when 50 µl
of the samples were injected onto the analytical column. Recovery of anions in
spiked samples ranged from 90.44% to 108.88% with the time of analysis being less
than 10 min. The statistical evaluation of the method was examined performing
intra-day (n = 8) and inter-day calibration (n = 10) and found to be satisfactory with
high accuracy and precision results. The applicability of the method was
demonstrated on the analysis of drinking water: tap, table and mineral.

Abstract: For the purpose of a pharmacokinetic study in the comparison of two
intravenous pharmaceutical formulations of the cardioprotective agent dexrazoxane,
we have developed an High Performance Liquid Chromatographic (HPLC) assay to
quantify the drug in human plasma and urine. The plasma sample pretreatment
involved a protein precipitation step with acetonitrile followed by an extraction with
10% 2-methyl-2-propanol in chloroform (v/v). Urine samples were diluted in
distilled water and subsequently extracted with 10% 2-methyl-2-propanol in
chloroform (v/v). After evaporation of the organic solvents, the residues were
dissolved and analysed on a µBondapak Phenyl column with a mobile phase
consisting of 0.01 M potassium phosphate pH 4.7 and methanol (8: 2, v/v). Detection
was performed at 208 nm. The lower limit of quantitation was 0.1 µg/mL and 10
µg/mL for plasma and mine respectively, using 1.0 mL sample volumes. The
usefulness of the method has been demonstrated in clinical samples originating from
patients treated with dexrazoxane. Dexrazoxane is not stable in plasma at ambient
temperature: after 6.5 hours the initial concentration was 42.6±1.0% (n = 3) of the
original concentration of 100 µg/mL. After sampling in the clinic, plasma samples
should be stored immediately at-30 C. Under these conditions dexrazoxane is stable
for at least 5 months. In urine the drug is stable for 24 hours when stored at 4-8 C.

An aliquot of the voided urine sample can be stored at-30 C for at least 4 months
without drug decomposition.

Science-Physics, B31 (1), 1-9.
Abstract: The equilibrium swelling of semicrystalline or crosslinked polymers and of
their gels upon immersion in liquids has been investigated extensively. On the other
hand, few studies have dealt with the kinetics of swelling. Swelling kinetics are
important for designing controlled-release devices for drugs and agricultural
pesticides based on swellable polymer matrices, and for predicting the release rates
of the active ingredients. Theoretical considerations, based on diffusion-controlled
swelling, show that first-order kinetics does not apply, even though deviations during
the initial and even middle stages of the swelling process may be relatively small.
Extensive studies of swelling rate and equilibrium swelling of supported and
unsupported gelatin films have been published. The rate is controlled by stress
relaxation in the swelling polymer network. The rate equations of these studies,
which have also been reported to apply to cellulose, are shown to represent
second-order kinetics with respect to the remaining swelling capacity. An
interpretation for the applicability of second-order kinetics to the swelling of
semicrystalline polymers such as gelatin and cellulose is given.

Abstract: Competitive adsorption of heavy-metal ions, i.e., Cd(II), Cu(II) and Pb(II),
from aqueous media onto monodisperse polystyrene (PS) microspheres carrying
dithiocarbamate groups were investigated. The crosslinked PS microspheres (2 µm in
diameter) were produced by dispersion polymerization, and then dithiocarbamate
groups were incorporated by a two-step procedure. The adsorption rate and capacity
of these sorbents for selected heavy metal ions from aqueous media containing
different amounts of these ions (0.05-600 ppm) and at different pH of 3.0-8.0 were
investigated. Very high adsorption rates were observed at the beginning, and
adsorption equilibria were then gradually achieved in about 5-90 minutes. The
maximum adsorptions of metal ions onto the dithidcarbamate modified PS
microsphere were 205.8 mg, 126.0 mgand 129.1 mgper gram of the sorbent
microspheres for Pb(II), Cd(II) and Cu(II), respectively. When the metal ions
competed (in the case of the adsorption from their mixture) the amounts of
adsorption of metal ions were quite close. Desorption of metal ions were studied by
using different eluent volume (20-200 ml) with 0.5 M NaCl. High desorption ratios
(more than 90%) were achieved in all cases. Adsorption-desorption cycles showed
the feasibility of repeated uses of this sorbent system.

Abstract: Poly(2-octadecyl-butanedioic acid), prepared from polyanhydride PA-18,
possesses novel heavy metal adsorption characteristics. The adsorption capacity of
this water insoluble polymer for lead(II) was substantially higher than other
237
heterogeneous adsorbants and is equivalent to those obtained with homogeneous
sorbants. The polymer exhibited pseudo-second-order kinetics and nearly complete
adsorption of lead occurred in 15 min with initial lead(II) concentrations greater than
100 mg.L-1. Adsorptive behavior was accurately predicted by the
Dubinin-Radushkevich isotherm model. The mean free energy of adsorption of
lead(II) onto poly(2-octadecyl-butanedioic acid) was determined to be 31.6 kJ.mol-1,
suggesting an ion exchange component to the adsorption mechanism. Gibb’s free
energy values for this process indicate that it is spontaneous. Adsorption was
relatively independent of pH in the range of 3-5, due to the utilization of the sodium
carboxylate form of the chelating groups, and was not influenced by high Na+
concentration and moderate concentrations(up to 200 mg.L-1) of Ca+2. Lead(II)
solutions containing 2000 mg.L-1 Ca+2 did reduce the adsorption of 2000 mg.L-1
lead(II) by 28%.

Abstract: The adsorption of Cu(II) ions onto the chitosan derived Schiff bases obtained
from the condensation of chitosan with salicyaldehyde (polymer I),
2,4-dihydroxybenzaldehyde (polymer II) and with 4-(diethylamino) salicyaldehyde
(polymer III) in aqueous solutions was investigated. Batch adsorption experiments
were carried out as a function of contact time, pH, and polymer mass. The amount of
metal-ion uptake of the polymers was determined by using atomic absorption
spectrometry (AAS) and the highest Cu(II) ions uptake was achieved at pH 7.0 and
by using sodium perchlorate as an ionic strength adjuster for polymers I, II, and III.
The isothermal behavior and the kinetics of adsorption of Cu(II) ions on these
polymers with respect to the initial mass of the polymer and temperature were also
investigated; adsorption isothermal equilibrium data could be clearly explained by
the Langmuir equation. The experimental data of the adsorption equilibrium from
Cu(II) solution correlates well with the Langmuir isotherm equation.

Abstract: This work illustrates the modification of polypropylene (PP) films through its
grafting with glycidylmethacrelate monomer (GMA). Further chemical treatment of
PP-g-GMA to convert epoxy groups into amine groups is discussed. Different factors
affecting the grafting percent such as solvents, monomer concentrations, irradiation
dose have been studied. Fourier transform infrared (FTIR) and thermogravimetric
(TGA) analysis confirm the grafting of PP. Morphological changes of PP,
PP-g-GMA and treated PP-g-GMA are confirmed by scanning electron microscopy
(SEM). The X-ray diffraction (XRD) pattern shows changes in the crystallinity on
grafting. Adsorption and kinetic studies of mercury onto the prepared PP grafted and
chemically treated films in sorption of Hg+ 2 metal ions from aqueous solutions have
been studied. The experimental data fit favorably to the Langmuir isotherm with a
high correlation coefficient. Moreover, the pseudo first and second order kinetics is
also indicated. The results suggest that the pseudo-second-order kinetic model better
represent the adsorption kinetics, suggesting that the adsorption process may be
chemisorptions. It is more likely to predict that the adsorption behavior may involve
valence forces through the sharing of electrons between Hg2+ and adsorbent. On the
basis of these investigations, the applicability of the prepared membranes is
discussed. Also the confirmation of metal ions adsorbed was confirmed using EDS
spectrometric techniques.

Abstract: In this study, magnetic metal-chelate beads, m-poly(ethylene glycol
dimethacrylate-vinyl imidazole) [m-poly(EGDMA-VIM)] with an average diameter
150-200 m was synthesized by copolymerizing ethylene glycol dimethacrylate
(EGDMA) with vinyl imidazole (VIM). The spesific surface area of the
m-poly(EGDMA-VIM) beads was found 63.1 m2/g. Cu2+ ions were chelated on the
m-poly(EGDMA-VIM) beads and used in immobilization of Aspergillus niger
glucoamylase in a batch system. The maximum glucoamylase adsorption capacity of
the m-poly(EGDMA-VIM)-Cu2+ beads was observed as 120 mg/g at pH 6.5. The
optimum pH for free and m-poly(EGDMA-VIM)-Cu2+ immobilized glucoamylase
were found 4.0 and 4.5, respectively. The optimum temperature of glucoamylase was
not changed after immobilization and determined as 60oC for free and immobilized
enzyme preparations. The glucoamylase adsorption capacity and adsorbed enzyme
activity slightly decreased after 10 batch successive reactions, demonstrating the
usefulness of the enzyme-loaded beads in biocatalytic applications. Storage stability
was found to increase with immobilization. The effect of various experimental
parameters such as pH, glucoamylase concentration, contact time and temperature in
aqueous solution were also investigated. Adsorption isotherm obtained for
m-poly(EGDMA-VIM)-Cu2+ was consistent with Langmuir model. Kinetic studies
showed that the adsorption process agreed with both the pseudo-second-order kinetic
model and the modified Ritchie’s-second-order kinetic model. Various
thermodynamic parameters, free energy (G0), enthalpy (H0) and entropy (S0), were
also calculated and the results showed that the adsorption process strongly depended
on temperature of medium.

Abstract: Fast response hydrogels have attracted great attention recently. Three kinds of
models with different complexity are available in the literature to investigate their
volume variation kinetics. A phenomenal model based on second-order reaction
kinetics provides a simple method to correlate the experimental kinetic data. A power
law model can be employed to evaluate different volume variation mechanisms
according to the diffusion exponential coefficient. The multi-field model
incorporates mechanical deformation with the diffusion of ion species. The volume
variation rate is dependent on both hydrogel molecular design and operation

A systematic review of compliance with palivizumab administration for RSV
immunoprophylaxis. Journal of Managed Care Pharmacy, 16 (1), 46-58.
Abstract: BACKGROUND: Respiratory syncytial virus (RSV) is a leading cause of
lower respiratory tract infection (LRTI) in infants and young children, accounting for
approximately 75,000-125,000 hospitalizations per year. It is estimated that in 2000,
RSV infection accounted for 1.7 million office visits, 402,000 emergency room visits,
and 236,000 hospital outpatient visits per year for children younger than 5 years of
age. Palivizumab, a humanized monoclonal antibody directed against RSV, is the
only immunoprophylaxis therapy approved by the FDA for prevention of serious
lower respiratory tract disease caused by RSV in infants (up to 2 years of age) who
meet 1 or more of the following criteria for high risk: (a) gestational age up to 35
weeks; (b) diagnosis of chronic lung disease (CLD, formerly bronchopulmonary
dysplasia [BPD]); or (c) diagnosis of cyanotic or complex congenital heart disease.
The RSV season typically occurs between November and March but may vary by
region. During the period of our review, depending on local duration of the RSV
season, infants usually required 5 monthly (every 28-30 days) intramuscular
injections of palivizumab. Infants born in the middle of the season received their
palivizumab doses from the time of birth to the end of the season and, therefore, may
have required less than 5 doses. It is unclear if compliance with monthly doses is a
problem and whether noncompliance increases the risk of RSV hospitalizations in
routine clinical practice. OBJECTIVES: To (a) identify and describe compliance
rates and the factors that influence parental compliance with immunoprophylaxis
regimens, (b) review intervention programs and describe those that have been
associated with increased compliance, and (c) summarize the association of
242
compliance with RSV hospitalization rates. METHODS: An electronic literature
search was conducted using journal databases, including Ovid, Current Contents,
EMBASE, MEDLINE In-Process & Other Non-Indexed Citations; Ovid MEDLINE,
PUBMED, and Web of Science; and an abstract database, Medical Intelligence
Solution, for citations through April 2008. Specific search terms used were
palivizumab with patient compliance, patient adherence, or patient persistence.
RESULTS: Twenty-five articles and abstracts met the inclusion criteria. Available
studies were mostly retrospective or observational prospective. Compliance, defined
in various ways across the studies, varied between 25% and 100%, and 12 studies
identified some of the factors related to noncompliance. Compliance generally was
lower among Medicaid patients, African American patients, and other minorities.
Ten studies (3 manuscripts and 7 abstracts) investigated the association of
administration of prophylaxis through monthly home visits by a health professional
with parental compliance with therapy. Most of the home-based programs were
associated with higher compliance rates compared with clinic or office programs.
Rates as high as 94% and 64% were achieved when Medicaid infants and infants of
minority descent, respectively, received their doses through a home health program.
When these infants received their doses at a clinic or office, depending on the
definition of compliance, rates were 61%-100% for Medicaid infants and 44% for
infants of minority descent. Reminder telephone calls to parents or caregivers,
comprehensive multidisciplinary programs that included extensive counseling of
parents, calendars with sticker reminders, and education in the language native to
parents also were associated with increased compliance, although statistical
significance was reported in only 1 study. Several studies recommended educating
parents on the benefits of RSV prophylaxis, alleviating transportation and language
difficulties, recognizing cultural differences and biases, and clarifying misperception
of RSV illness severity. Home health programs had lower rates of RSV
hospitalizations than office-based programs in 3 analyses conducted in 2 studies. In 4
other abstracts, the rates of RSV hospitalization for home health programs and
office-based administration did not significantly differ. In a large, 4-season,
prospective outcome study, compliant infants had lower RSV hospitalization rates
than those who were not compliant under one definition of compliance (doses within
35-day intervals). RSV hospitalization rates were not significantly different using
another definition of compliance (receipt of anticipated doses, expected vs. observed
rates). In a large survey of 10,390 infants identified from pharmacy dispensing
records, RSV hospitalization rates were 1.4% in the compliant group versus 3.1% in
the noncompliant group (OR = 2.2, 95% CI = 1.4-3.5, P<0.001). Adjustment for
confounding was not reported in these studies. CONCLUSION: Medicaid and
minority infants were less likely to receive scheduled palivizumab doses.
243
Home-based programs for the administration of palivizumab have been investigated
more than other interventions and are associated with improved compliance
compared with office-based administration. Compliance with dosing, in general, was
associated with lower RSV hospitalization rates. However, these strategies should be
further investigated using well-designed studies.

determinants of university and author impact in the management literature in the past
quarter century. Journal of Management, 34 (4), 641-720.

Abstract: The purpose of this study is to identify the universities and research scholars
who have had the greatest impact on the field of management during the past quarter
century and the factors that influence their impact. Using bibliometric techniques, the
authors examined 30 management journals to identify the 100 most-cited universities
and 150 most-cited authors from 1981 to 2004. The analysis included more than
1,600 universities and 25,000 management scholars across five individual time
periods. The findings showed that (a) a relatively small proportion of universities and
scholars accounted for the majority of the citations in the field; (b) total publications
accounted for the majority of the variance in university citations; (c) university size,
the number of PhDs awarded, research expenditures, and endowment assets had the
biggest impact on university publications; and (d) total publications, years in the field,
graduate school reputation, and editorial board memberships had the biggest effect
on a scholar’s citations.

Full Text: 1999\J Man His5, 320.pdf
Abstract: While management is considered relatively immature compared to other
social sciences, for over half the lifespan of the discipline, the field has been
bombarded with “fads”. For the purposes of this manuscript, fads are defined as
“managerial interventions which appear to be innovative, rational, and functional and
are aimed at encouraging better organizational performance”. This definition draws
on and integrates a number of theorists’ conceptualizations of fads. Notably, however,
there is some point at which a fad sufficiently demonstrates its effectiveness in
numerous and diverse settings to warrant an evolution from fad status to something
which implies more permanence. This issue is addressed in a theoretical model
which traces the process of fad adoption using historical bibliometric data. The
model offers propositions concerning the precursors, moderators, and outcomes of
adoption.

Abstract: Recent management history has seen a surge in the number of ideas that
supposedly represent the cutting edge of management progress. This paper
investigates the emergence of several of these management fashions. It examines the
dissemination of fashions and the type of journals and areas from which particular
fashions emerge. A bibliometric analysis is described that involved the following
246
fashions: bench-marking; pay for performance; quality circles; peer review; and
MBO. The results of the analysis support hypotheses that fashions emerge in the
popular press before academic literature and that some fashions emerge from
sub-fields before appearing throughout management publications.

Abstract: Although applauding the application of bibliometric techniques to an analysis
of the management literature, this author presents an alternative interpretation to A.
Lockett and A. McWilliams’s (2005) conclusion that, in general, the citation patterns
of selected management journals compare “unfavorably” with a set of “core”
journals from economics, psychology, and sociology. In doing so, the author
discusses methodological and theoretical issues related to assessing the management
discipline’s influence on science as a whole.

Abstract: This study investigates the appropriateness of using publication of an article in
a top (specifically, top five) management journal as a proxy for its quality. Social
Science Citation Index citation counts were collected over 7-year event windows for
articles published in 34 management journals in 1993 and 1996. Overall, the authors
found that articles published in the five journals most often considered to be the top
ones in management tend to be cited more often than ones published in the other
journals. Far more important, however, across three different criteria for placing
articles into top versus non-top categories, there were substantial classification errors
248
from using journal ranking as a proxy for quality. This finding suggests that both
administrators and the management discipline will be well served by efforts to
evaluate each article on its own merits rather than abdicate this responsibility by
using journal ranking as a proxy for quality.

Abstract: Presents the results of a qualitative analysis of copies of The Hospital, a
journal for UK hospital administrators, from 1946-1948: immediately prior to the
establishment of the NHS. Characterises administrators in that period as kindly
technicians. Analyses administrators’ ways of thinking; spheres of influence and
level of education. Also notes their concern for the running of support services; their
implicit and unexamined deference to medical staff and an explicit belief in the need
to carry out their role with kindliness. Concludes by highlighting the changes in
managerial thinking between the 1940s and today and speculates that these changes
may be best understood, following Foucault, as phenomena of rupture and
discontinuity rather than as linear progression.

Abstract: P>Social trends that raised the value of esoteric expertise, stimulated the
creation of knowledge-intensive firms and so created an opportunity to study some
organizations that academics had overlooked. A lack of presuppositions, a useful
research method, and thoughtful experts in these firms helped to uncover some
surprising behaviours. The resulting paper attracted citations and may have
stimulated research about knowledge as a business resource and a managerial
challenge. However, the topic continues to pose questions for further research.

Abstract: Objective: To assess the efficacy of chiropractic for patients with back pain.
Data Sources: Randomized clinical trials (RCTs) on spinal manipulation were identified
with a Medline search (1966-1990), by citation tracking, and by manual examination
of the relevant chiropractic reference systems [Chiropractic Research Archives
Collection and Index to Chiropractic Literature]. [Indexing terms, Medline: backache,

therapists. To find additional evidence from nonchiropractic RCTs, chiropractic
standards similar to the type of treatment used in nonchiropractic trials were
252
determined by a panel of blinded chiropractors.
Data Extraction: Review by two blinded reviewers independently, using a list of
methodological criteria, each of which was attached to a weight. The maximum was
set at 100 points.
Data Synthesis: We identified five chiropractic RCTs. No similarity to chiropractic
standards could be detected in any of the nonchiropractic RCTs. No chiropractic
RCT had a methodological score of more than 50 points. The authors of four of the
trials report favorable results for chiropractic, while one refrains from drawing
conclusions. The results of the chiropractic RCTs differed on the timing of maximal
effect as well as on the subgroups showing the best treatment results.
Conclusions: Although the small number of chiropractic RCTs and the poor general
methodological quality precludes the drawing of strong conclusions, chiropractic
seems to be an effective treatment of back pain. However, more studies with a better
research methodology are clearly still needed.

Abstract: Objective: To examine the neurophysiologic dura mater and the rectus capitis
posterior minor muscle in the etiologic proposition of cervicogenic headache.
Data Sources: On-line searches in MEDLINE and the Index to Chiropractic Literature,
manual citation searches, and peer inquiries.
Results: Connective tissue bridges were noted at the atlanto-occipital junction between
the rectus capitis posterior minor muscle and the dorsal spinal dura. The
perpendicular arrangement of these fibers appears to restrict dural movement toward
the spinal cord. The ligamentum nuchae was found to be continuous with the
posterior cervical spinal dura and the lateral portion of the occipital bone. Anatomic
structures innervated by cervical nerves C1-C3 have the potential to cause headache
pain. Included are the joint complexes of the upper 3 cervical segments, the dura
mater, and spinal cord.
253
Conclusion: A sizable body of clinical studies note the effect of manipulation on
headache. These results support its effectiveness. The dura-muscular,
dura-ligamentous connections in the upper cervical spine and occipital areas may
provide anatomic and physiologic answers to the cause of the cervicogenic headache.
This proposal would further explain manipulation’s efficacy in the treatment of
cervicogenic headache. Further studies in this area are warranted to better define the
mechanisms of this anatomic relationship.

Abstract: Background: The number of studies that have investigated the direst analgesic
effect of a spinal manipulation on spinal or referred pain is small, making knowledge
of this crucial aspect of manipulation sparse. This paper reviews a set of studies that
measure the immediate effect of manipulation on pain or pain-related phenomena in
the spinal and peripheral soft tissues.
Methods: The literature was accessed through MEDLINE. Key words used were
“ manipulation, “ “pain.” and “chiropratic.” This search was complemented by
citation reviews of important research and chapters on the topic. Only studies that
directly measured the effect of at least a single spinal manipulation on pain (eg,
tenderness, biochemical assay, referred pain) were selected. The selected studies
were reviewed descriptively; no systematic assessment of their quality was
conducted.
Results: The electronic search yielded 738 citations. Six hundred and forty-two were
relevant to chiropractic. Of these, most were clinically descriptive articles about
diagnostic and therapeutic procedures or case management. Most of the remaining
articles were clinical trial reports or letters to the editor. Only 5 studies were selected
according to the established criteria. Thus less than 1 % of the indexed literature on
chiropractic, manipulation, and pain involved studies that explored the mechanism of
the putative effect of spinal manipulation on pain mechanisms. Six other studies were
retrieved from citation reviews. These 11 studies were reviewed in order of
publication.
Conclusion: Few studies have investigated the effects of spinal manipulation on pain
directly. If the theory of manipulation exerting its therapeutic effects posits that the
sensory input created by the intervention results in some form of inhibition of pain,
then the results of these studies largely consistent with one another and with this
theory. This review has highlighted the deficiencies in the errant studies and many
remaining questions. Only more high-quality research will per mit a full elucidation
254
of the hypoalgesic effects of spinal manipulation.

Abstract: Objective: To provide a rationale for the examination of posture from a
dynamic (behavioral) perspective and to relate the vertebral subluxation to postural
instability and motion sickness via inefficiency.
Data Collection: A manual search of available reference texts and a computer search of
literature-from Index Medicus, PsycINFO, and ISI Science Citation Index Expanded
were collected with an emphasis on postural dynamics, vertebral subluxation, and
motion sickness.
Results: Evidence linking behavioral and health research has emerged from the study of
posture and postural dynamics. Studies: examining the relation between postural
control and motion sickness have shown that motion sickness is preceded and
predicted by postural instability. Motion sickness is characterized by maladaptive
response to unusual motion events. The symptoms are nonspecific and variable.
Although the Postural Instability theory of motion sickness predicted that instability
should precede sickness, it did not make any claims regarding the symptoms
associated with it. Chiropractic literature has emphasized the effects of vertebral
subluxation on neurologic dysfunction. Vertebral subluxation is a condition that is
postulated to interfere with neurologic processes and may influence organ system
function and general health. As in the case of motion sickness, symptoms are
nonspecific and variable (and in some instances the person may have no symptoms).
So what do these disorders have in common? In each instance the disruptions lead to
inefficiency in the system.
Conclusion: Given this potential commonality, we propose that some of the methods
used by behavioral researchers to study postural dynamics may also be of great
utility to health care practitioners and psychologists alike. Furthermore we propose
that this link will provide a framework that will allow scientists to address seemingly
intractable problems such as motion sickness or subluxation.

Abstract: Objective: To present a descriptive review of abdominal aortic aneurysm
(AAA), including a review of risk factors for and case finding in AAA for

Data Sources: Clinical and scientific literature identified through various sources
including MEDLINE and citation tracking.
Data Synthesis: Selective narrative review of relevant literature.
Results: AAA may be asymptomatic; however, back pain is a common presenting
feature. Risk factors include male gender, increasing age, cigarette smoking,
hypertension, chronic obstructive airway disease, claudication, and AAA in a
first-degree relative. AAA should be considered in the differential diagnosis of older
white patients, especially males, with low back pain. Estimated prevalence for AAAs
in older males is in the order of 3% to 5%; rupture accounts for 1.7% of deaths in
men aged 65 to 75 years. Elective surgical resection of AAAs (prior to rupture)
offers a low operative mortality and good prognosis.
Conclusion: AAA should be considered in the differential diagnosis of older patients
presenting with low back pain and those with risk factors for AAA. Chiropractors, as
primary contact health care practitioners, have a responsibility to refer patients
suspected of having AAA for appropriate imaging and, where indicated, vascular
surgical opinion.

Pediatrics (JCCP). Methods: The content of the 13 existing issues of the JCCP
(1996-2007) were assessed. Articles were categorized by type, and information
concerning author affiliation, academic/professional background and gender were
tabulated. A second-level analysis applied specific criteria checklists to applicable
articles to determine the quality rating of each paper. Results: There were 72 articles
included in the analysis, of which 46% were case reports, 17% editorials, 13% case
series, 10% narrative literature reviews, 10% commentaries, 4% “other,” and 1%
cross-sectional studies. Seventy-five percent of the authors were “private
practitioners.” A certification in chiropractic pediatrics was held by 43% of the
256
authors; 65% of the authors were females, and 83% of the articles had a single author.
After applying the checklist to specific articles, 13 articles (18%) scored 40% or
better (range of 40%-67%), whereas 59 articles (82%) scored less than 40%.
Conclusions: The findings of this analysis suggest there is room for improvement in

adsorbing in Cr, Pb, and Feion in solutions. The adsorption rates were above 95% at
pH 5.0, 25C, in 10 mg/liter of each metalsolution. The gel beads formed by the CBP
were stable within the range of pH 4.0-7.0 and at a temperature of 40-55C, The
optimum pH and temperature of the immobilized glucoamylase by the CBP gel
beads (poly-G) were 5.0 and 45C, respectively. The immobilized glucoamylase
produced 10.5 mg/liter of glucose from 10 mg/ml of soluble starch.

studied. In this research, the batch removal of toxic hexavalent chromium ions from
wastewater and aqueous solution using two different activated carbon marine algae
Gracilaria (red algae) and Sargassum sp. (brown algae) were examined. Activated
carbon prepared from Gracilaria and Sargassum sp. The chromium uptake was
dependent on the equilibrium pH and chromium concentration, with pH = 2.0, being
the optimum pH value. The experimental adsorption data were fitted to the Langmuir
and Freundlich adsorption model. The maximum efficiencies of chromium removal
were 91.53% and 91.98% for activated carbon prepared of Gracilaria and Sargassum
sp., respectively. A significant fraction of the total chromium(VI) uptake was
achieved within 60 min. The chromium(VI) uptake by the biosorbents was best
described by pseudo-second order rate model. This investigation verifies the
possibility of using activated carbon prepared from algae as valuable material for the
removal of chromium from aqueous solution and wastewater.

Abstract: In the early 1990s, scholars from a variety of disciplines encouraged greater
inclusion of qualitative research methodology in the mental health field. Moon,
Dillon, and Sprenkle (1990) hoped their paper “Family therapy and qualitative
research” would serve as a stimulus for further development of qualitative research
in the field of family therapy. Ten years later entering the new millennium, has the
field been influenced by recommendations for an increase in use of qualitative
methodology in family therapy? A content analysis was conducted on articles
published in the marriage and family therapy literature from 1980 to 1999. Of the
numerous articles examined in four journals, 131 articles were published using
qualitative research methodology. Findings support the contention that qualitative
research is increasing, but still accounts for a small number of research articles
published in marriage and family therapy journals.

Abstract: The authors investigate the overall and subarea influence of a comprehensive
set of marketing and marketing-related journals at three points in time during a
30-year period using a citation-based measure of structural influence. The results
show that a few journals wield a disproportionate amount of influence in the
marketing journal network as a whole and that influential journals tend to derive their
influence from many different journals. Different journals are most influential in
different subareas of marketing; general business and managerially oriented journals
have lost influence, whereas more specialized marketing journals have gained in
influence overtime. The Journal of Marketing emerges as the most influential
marketing journal in the final period (1996-97) and as the journal with the broadest
span of influence across all subareas. Yet the Journal of Marketing is notably
influential among applied marketing journals, which themselves are of lesser
influence. The index of structural influence is significantly correlated with other
objective and subjective measures of influence but least so with the impact factors
reported in the Social Sciences Citation Index. Overall, the findings demonstrate the
rapid maturation of the marketing discipline and the changing role of key journals in
the process.

Abstract: Why do some articles become building blocks for future scholars, whereas
others remain unnoticed? The authors aim to answer this question by contrasting,
synthesizing,
and
simultaneously
testing
three
scientometric
perspectives-universalism, social constructivism, and presentation-on the influence
of article and author characteristics on article citations. They study all articles
published in a sample of five major journals in marketing from 1990 to 2002 that are
central to the discipline. They count the number of citations each of these articles has
received and regress this count on an extensive set of characteristics of the article
(i.e., article quality, article domain, title length, the use of attention grabbers, and
expositional clarity) and the author (i.e., author visibility and author personal
promotion). They find that the number of citations an article in the marketing
discipline receives depends more on “what is said” (quality and domain) and “who
says it” (author visibility and personal promotion) than on “how it is said” (title
length, the use of attention grabbers, and expositional clarity). The insights gleaned
from this analysis contribute to the marketing literature and are relevant to scientific
stakeholders, such as the management of scientific journals and individual academic
scholars, as they strive to maximize citations. They are also relevant to marketing
practitioners; they inform practitioners on characteristics of the academic journals in
marketing and their relevance to decisions they face. Conversely, the insights also
raise challenges regarding how to make journals accessible and relevant to marketing
practitioners: (1) Authors visible to academics are not necessarily visible to
practitioners; (2) the readability of an article may hurt academic credibility and
impact, but it may be instrumental in influencing practitioners; and (3) it remains
questionable whether articles that academics assess to be of high quality are also
managerially relevant.

Abstract: Institutional competition to retain and recruit marketing scholars capable of
publishing in the leading marketing journals has intensified. Although increased
emphasis has been placed on publication productivity in the leading marketing
journals, little is known about questions such as (1) What level of publication
productivity in the leading marketing journals does it take to get promoted in
263
marketing academia? (2) What level of publication productivity in the leading
marketing journals warrants exception? and (3) What drives research productivity in
the leading marketing journals? The authors draw on the economic concept of
imperfect substitution to address these questions using two data sets: (1) a census of
publication activity in the leading marketing journals of 337 scholars in the top 70
institutions who were promoted between 1992 and 2006 and (2) an examination of
2672 scholars who published 3492 articles in the four leading marketing journals
over the 1982-2006 period. The results indicate that the average number of
publications by successful candidates for promotion to associate professor from PhD
conferral at the top 10 institutions was .57 articles in the leading marketing journals
per year, compared with .47 in the top 11-20 institutions, 47 in the top 21-40
institutions, and .26 in the top 41-70 institutions. The authors also present findings
related to promotion to full professor both from PhD conferral and from promotion to
associate professor, as well as scholars identified as warranting exceptional
publication productivity. The findings provide substantive implications for marketing
academics, for those involved with the recruitment and retention of marketing
academics, and for the field of marketing thought in general.

Abstract: This research demonstrates that several quantifiable characteristics of articles
in the marriage and family area are substantially related to subsequent impact in the
field, based on bibliometric citation analysis. Articles are more frequently cited when
they are explicitly linked to prior literature in the marriage and family field, to more
current ongoing research not yet published, and to contemporary theorists in gender
and sex roles. Consistent with studies of other science fields, the works published by
the more eminent, highly cited scholars are more likely to be cited. However,
contrary to other fields, collaborative work in marriage and the family does not yield
higher visibility. The implications of these results to the field are discussed, and
further analyses are proposed to supplement this bibliometric assessment and to
explore some tentative conclusions.

the two key factors which influence the removal of calcium and magnesium in

temperature, the modified Na-X zeolite was more efficient than the Na-A
commercially used in detergency, for both Ca and Mg ions.

Abstract: Titanium pillared clays using montmorillonite, saponite and rectorite hosts
have been prepared from TiCl4-ethanol solutions. The products have been
characterised structurally by PXRD and IR studies and for acidity by
cyclohexylamine and pyridine adsorption-desorption studies. Catalytic activity data
for pentanol dehydration and cumene cracking are also presented. The amount of Ti
incorporated is related to the cation-exchange capacity of the host. The thermal
stability of the pillared material decreases from rectorite through montmorillonite to
saponite. Cyclohexylamine desorption suggests that the saponite,sample has the
highest acidity, and this is reflected in the highest conversion for cumene cracking. In
the case of pentanol dehydration, however, the highest activity is seen for the
266
rectorite sample, despite its apparent lower acidity. Similar effects have been
reported previously for this reaction with alumina pillared clays.

Abstract: An inorganic molecular imprinted polymer (IMIP) coated photocatalyst for
photodegradation of diethyl phthalate (DEP) was synthesized by coating a layer of
molecular imprinted silica/alumina on the surface of TiO2 nanoparticles with DEP as
the template. The characterization with HR-TEM, XRD, FT-IR and UV-visible
spectroscopic analysis indicated that the new catalyst was a composite of the TiO2
particle core and a shell layer of Al3+-doped silica with thickness of about 5 nm. The
Al-27 MAS NMR measurements revealed that the IMIP layer consisted of
framework
tetrahedrally
coordinated
aluminium
and
non-framework
octa-coordinated aluminium species, both of which function as the hot spots for the
adsorption of target molecules on the catalyst during photocatalysis. It was found that
the IMIP layer provided the photocatalyst with molecular recognition ability, leading
to selective adsorption and rapid mineralization of the target pollutant from its low
level solution (2 mg L-1) in the presence of other high level non-target pollutants,
such as phenol (50 mg L-1). Unlike the neat TiO2 photocatalyst (Degussa P25), the
use of the IMIP-coated TiO2 photocatalyst almost eliminated the generation of toxic
aromatic byproducts. Moreover, the new photocatalyst was totally constructed by
inorganic compounds, being resistant to photochemical attack and showing favorable
lifetime during the photocatalysis.

Investigation of synthesis mechanism and evaluation of physicochemical properties.

Full Text: 2009\J Mat Che19, 7263.pdf
Abstract: Steel slag is a commercial waste material mainly consisting of SiO(2),
Al(2)O(3) and CaO, the former two chemicals being major components of zeolites
and the latter a major component of hydroxyapatite (HAP). A hydroxyapatite-zeolite
composite material (HAP-ZE) was successfully synthesized from steel slag by
adding appropriate chemical reagents, H(3)PO(4) and NaOH, via aging at 363 K for
approximately 2 days. The synthesis mechanism and structural properties were
clarified by detailed analysis using XRD, FT-IR, SEM, EDX, elemental mapping,
and N(2) adsorption-desorption measurements. The Ca and Mg components were
chemically reacted with phosphate in the early stages of aging, being precipitated as
Mg-substituted HAP with (Ca + Mg)/P = 1.67. After 2 days of aging,
well-crystallized HAP and faujasite-type zeolite (Na type X-zeolite with
SiO(2)/Al(2)O(3) = 2.4) were separately formed via a non-simultaneous
crystallization process. The over-run in aging time led to phase transformation from
FAU-zeolite to Pl-zeolite. The minor components in steel slag such as Fe and Mn
had little effect on the synthesis of HAP-ZE; however, the inherent SiO(2)/Al(2)O(3)
ratio in steel slag led to a lower yield from the zeolite phase. Furthermore, from the
adsorption assessment of volatile organic compounds (VOCs), fatty acid and protein,
the HAP-ZE synthesized under optimum conditions was found to have adsorption
properties comparable to those of pure zeolite and HAP.

Removal efficiency of arsenate and phosphate from aqueous solution using layered
double hydroxide materials: Intercalation vs. precipitation. Journal of Materials
Chemistry, 20 (22), 4684-4691.
Full Text: 2010\J Mat Che20, 4684.pdf
Abstract: Adsorption behaviours of arsenate and phosphate over Mg-based and
Ca-based layered double hydroxide (LDH) adsorbents have been examined in
kinetics and thermodynamics. Removal of these anions from aqueous solution
follows the Lagergren first-order and/or pseudo-second-order model, and the
adsorption isotherm is well fitted with either the Langmuir or the Freundlich model.
Structure analysis of used LDH adsorbents reveals that two processes, i.e.
intercalation and precipitation, are responsible for the anion removal. Adsorption
268
over the Mg-based LDH adsorbent occurs by way of intercalation into the interlayer
spacing while that over the Ca-based adsorbent occurs by means of precipitation of
dissolved Ca2+ with the anion. More particularly, we have found that As(V) at a
concentration below 10 mg/L can be very efficiently removed through intercalation
into the interlayer of reconstructed MgAl-LDHs, with less than 0.010 mg/L of As left
in solution. We have also noted that phosphate at [P] up to 100 mg/L can be quickly
and effectively removed through precipitation with CaAl-Cl-LDH, giving rise to
similar to 0.1 mg/L of P left in solution with the maximum adsorption amount up to
135 mg/g. Therefore, these two LDH materials (calcined Mg3Al-CO3-LDH and
uncalcined Ca2Al-Cl-LDH) are potential cost-effective adsorbents for arsenate and
phosphate, respectively.

Abstract: Magnetic porous graphitic carbon (MPGC) materials were fabricated through
a facile “Solution-Solid” route and their application as excellent adsorbents for metal
ions and dye were also demonstrated. In the preparation, glucose, nickel nitrate and
TEOS were selected as carbon resource, catalyst precursor and porogent,
respectively. In the first step, the solution contained glucose, Ni2+ and TEOS was
treated at low temperature to impel polymerization of glucose, coordination of Ni2+
with glucose unit and hydrolysis of TEOS simultaneous, leading to the formation of
precursor (Solution process). After heating the precursors under N-2 atmosphere, the
Ni-SiO2/carbon composites were formed (Solid process). Followed soaking with
NaOH to remove SiO2 porogent, the corresponding MPGC materials with magnetic
nickel particles embedded in the graphitic carbon framework were obtained. The
obtained MPGC materials show good chemical stability due to their high graphitic
degree. It is noteworthy that they have exceptionally large surface areas up to 918 m2
g-1. The adsorption performance of MPGC are evaluated by using metal ions (Cd2+,
Cu2+, Ag+, Au3+) and dye (Rhodamine B, RhB) in aqueous solutions as the target.
The results indicate that MPGC materials exhibit excellent adsorption capacities for
269
metal ions (7.79 mg g-1 for copper for example), which are superior to those of
activated carbons and carbon nanotubes. In addition, the materials have also
exhibited good ability for adsorption of dye molecular. Notably, MPGC materials
could be easily removed for reuse by an external magnet, facilitating separation and
reuse of those materials as adsorbents. The adsorption kinetics for these metal ions
and dye on MPGC-based adsorbents were well fitted to a pseudo-second order
model.

Abstract: Hollow and core-shell polyaniline (PANI) micro/nanospheres have been
fabricated by a simple copper (II)-catalyzed self-assembly method under different
reagent concentrations. In this synthesis system, the copper(II) salt and the template
composed of aniline monomers were two key factors in the formation of PANI
spherical products. The molecular structure of the PANI prepared by the
copper(II)-catalyzed self-assembly method is similar to that of PANI prepared by
traditional methods as demonstrated by X-ray diffraction, Fourier-transform infrared
and Raman spectroscopy. The synthesized PANI hollow spheres and fiber/sheets
were used to adsorb methyl orange from aqueous solution. The results showed that
the adsorption/desorption kinetics and isotherms followed pseudo-second-order and
Langmuir models. Importantly, the as-synthesized PANI hollow spheres exhibited a
superior adsorption capacity (384.62 mg g-1) compared with other absorbents. The
excellent adsorption characteristic of the hollow PANI microsphere will render it an
ideal candidate for removal of organic dye from wastewater.

Abstract: Carboxylic acids produced by acid fermentation have attracted much attention
270
recently as promising chemical feedstock. The feasibility of the acid fermentation as
a high-value added bioconversion process depends on the selective separation of
carboxylic acids from the bulk solution. The authors synthesized an
aminopropyl-functionalized mesoporous silica nanoparticle (MSN) material with the
MCM-41 type, parallel channel porous structure via a co-condensation method. The
adsorption isotherms were analyzed with an extended Langmuir model using an
overloading term. The highest acid adsorption capacity was 3.38 mol kg-1 for 1 : 1
complexation at an amine density of 3.14 mol N kg-1. Positive isosteric heat showed
the reaction was exothermic and favored at low temperature. Desorption/regeneration
by increasing the pH to 10.5 was completed within 1 min, and the regenerated MSN
showed an adsorption capacity equivalent to the original. MSN had a high selectivity
for carboxylic acid over ethanol, glucose, and protein. The pseudo-second-order rate
constant for acetic acid adsorption on MSN was 0.41 kg mol-1 min, significantly
higher than those of an anion exchange resin (0.14 kg mol-1 min) and activated
carbon (0.06 kg mol-1 min). We envision that the MSN material could serve as an
efficient adsorbent for selective sequestration of biomass-derived carboxylic acids
for various applications.

onto
the
surface
of
aldehyde-functionalized fly-ash-cenospheres. Based on these MCs, the magnetic
molecularly imprinted polymers (MMIPs) were further synthesized and characterized,
and used to selectively recognise bisphenol A (BPA) molecules. Owing to the
intrinsic advantages of cross-linked chitosan, magnetic gamma-Fe(2)O(3)
nanoparticles and spherical FACs, the results demonstrated that these spherical
shaped MMIPs particles had magnetic sensitivity (M(s) = 2.221 emu g(-1)) and
magnetic stability (especially over the pH range of 6.0-12). Batch mode adsorption
studies were carried out to investigate the specific adsorption equilibrium, kinetics
and selective recognition. The Langmuir isotherm model was fitted well to the
equilibrium data of the MMIPs, and the monolayer adsorption capacity of the
MMIPs was 135.1 mg g(-1) at 298 K. The kinetic properties of the MMIPs were well
271
described by the pseudo-second-order equation, indicating the chemical process
could be the rate-limiting step in the adsorption process for BPA. Selective
recognition experiments demonstrated the high affinity and selectivity of MMIPs
towards BPA over competitive phenolic compounds. The molecular interaction
between BPA and methacrylic acid (MAA) was investigated by the (1)H-NMR
spectrum. Hydrogen bonding was proved to be mainly responsible for the
recognition mechanism, and the specific recognition effect may be based on the
distinct size, structure and functional group of the template molecules.

Abstract: The polyethyleneimine (PEI) functionalized biosorbent which uses an
eggshell membrane (ESM) as a model was synthesized based on the cross linking
reaction between aldehydes in glutaraldehyde and functional groups such as amines
and amides in ESM. The as-prepared biosorbent (PEI-ESM) strongly interacted with
chromium(VI). After modification, the dynamic uptake capacity of the PEI-ESM
increased by 105% compared with the control, and the maximum equilibrium
adsorption capacity for Cr(VI) can reach about 160 mg g-1 with an initial pH of 3.0.
The Langmuir adsorption isotherm was applicable to fit the removal process.
Kinetics of the Cr(VI) removal were found to follow a pseudo-second-order rate
equation. The results obtained by Raman spectroscopy and X-ray photoelectron
spectroscopic analysis (XPS), performed on the as-prepared biosorbent before and
after Cr(VI) adsorption, suggested that some of adsorbed Cr(VI) anions were reduced
to Cr(III) in Cr2O3 or Cr(OH)3 during the sorption process, demonstrating that the
PEI-ESM could detoxify Cr(VI). The developed biosorbent promises advantages
such as low cost, high adsorption capacity, Cr(VI) detoxification, and environmental
friendliness.

Abstract: This paper is a bibliometric study of the publication patterns of academic and
research scientists of Maghreb countries: Algeria, Morocco and Tunisia. The
comparative study of the scientific production in the countries of Maghreb is made
using Scopus data during the period 1996-2009. Results show that the total scientific
production of Tunisia is higher than that of both Morocco and Algeria, even though
the population in Tunisia is only one third of that of Morocco and Algeria.
Scientometric analysis is furthermore related to the population to each country. The
study deals also to introduce the Hirsch index called h-index of the most published
authors according to the Scopus database. Ten of the most published authors of each
country are listed and their corresponding h-index values were given.

Abstract: The present work examined the photocatalytic behavior of methylene blue
(MB) on titania-dispersed bamboo charcoals, prepared by sol-gel method combined
with chemical-wet impregnation. The experimental results of nitrogen adsorption
showed that specific surface area of the TiO2-charcoals was found to increase with
TiO2 loading, whereas their mean pore sizes exhibited a decreasing trend. It can be
suggested that TiO2 nanoparticles were mostly coated on the charcoal surface and
partially deposited in the mouth of pore channels. Our preparation technique for the
heterogeneous catalysts improves the dispersed degree of TiO2 catalyst, which shows
a better photocatalytic performance than pure TiO2 aggregation. A linearity
relationship between the overall photocatalytic efficiency and the TiO2 loading
reflected that each titania particle behaves an identical photocatalytic reactivity The
liquid-phase photocatalytic behavior of the heterogeneous catalysts can be well
described by Elovich kinetic model. (C) 2008 Published by Elsevier B.V.

diamond-oxygen reaction. Journal of Materials Research, 8 (11), 2870-2878.
Abstract: The kinetics of reaction between chemical vapor deposited diamond films
(prepared by the hot filament method) and oxygen gas was studied by
thermogravimetry. The reactions were carried out at atmospheric pressure in gas
mixtures containing between 25 and 100 vol. % oxygen (balance argon), and in the
temperature range of 973-1073 K. The apparent order of the reaction is close to 0.6,
and the apparent activation energy is 232 kJ/mole. The kinetic data are explained by
assuming no mass transfer limitations, direct reaction between CVD diamond and
oxygen to form CO and CO2, and thermodynamic equilibrium between CVD
diamond, CO, and CO2. The dominant chemical reaction involves the formation of
CO, while the formation of CO2 is not significant. Three stage mechanistic schemes
are developed involving adsorption of oxygen on CVD diamond surface, surface
chemical reaction, and desorption of adsorbed species to CO or CO2. The
experimental rate data conform to the reaction rate expressions developed for the
mechanistic schemes leading to the formation of CO and CO2, assuming adsorption
as the rate-controlling step. The adsorption rate constants for the formation of CO
and CO2 are determined. The activation energy of the adsorption step leading to the
formation of CO is 213 kJ/mole.

Abstract: The present communication reports the effect of a softening treatment carried
out with 18% NaOH on the fine structure and structure-property relations in coir
fibres. The effect of successive removal of lignin and hemicelluloses on the fine
structure has also been studied. Unlike other cellulosic fibres, alkali treatment failed
to produce any increase in fibre elongation in coir. However, the spiral structure was
found to be considerably modified by swelling. X-ray and infrared spectral
measurements revealed that a part of the noncellulosic components does occupy the
intracellular space and plays a significant role on fine structural changes produced
during the alkali treatment.

was studied in concentrations from 5×10-4 M to 1 M at a temperature of 298 K. The
inhibitor mechanism was treated as a substitutional adsorption process according to
Flory-Huggins, Dhar-Flory-Huggins and Bockris-Swinkels isotherms. The best
approach was obtained using the latter. A structural parameter, the projected

Abstract: The effects of environmental aging and accelerated aging on tensile and
flexural behavior of bamboo fiber reinforced polypropylene composite (BFRP) and
bamboo-glass fiber reinforced polypropylene hybrid composite (BGRP), all with a
30% (by mass) fiber content, were studied by exposing the samples in water at 25°C
for up to 1600 h and at 75°C for up to 600 h. Reduction in tensile strength for BFRP
and BGRP was 12.2% and 7.5%, respectively, after aging at 25°C for about 1200 h.
Tensile and flexural strength of BFRP and BGRP were reduced by 32%, 11.7%, and
27%, 7.5% respectively, after aging at 75°C for 600 h. While the strengths of the
bamboo fiber reinforced composites reduce with sorption time and temperature, the
environmental degradation process can be delayed by adding a small amount of glass
fiber. Moisture sorption and strength reduction are further suppressed by using
maleic anhydride polypropylene (MAPP) as a coupling agent in both types of
composite system. (C) 2003 Kluwer Academic Publishers.

Abstract: Four kinds of NH2-functionalized nano magnetic polymer adsorbents
(NH2-NMPs) coupled with different diamino groups, i.e., ethylenediamine (EDA),
diethylenetriamine (DETA), triethylentetramine (TETA), and tetraethylenepentamine
(TEPA), named as EDA-NMPs, DETA-NMPs, TETA-NMPs, and TEPA-NMPs,
respectively, have been prepared and characterized by transmission electron
microscopy (TEM), X-ray diffractometer (XRD), vibrating sample magnetometer
(VSM), elementary analyzer (EA), Brunauer, Emmett, Teller surface area analyzer
(BET), and Fourier transform infrared spectroscopy (FTIR). The sorptive
characteristics of the NH2-NMPs intended for removal of chromium(VI) was
investigated. Batch adsorption studies were carried out to optimize adsorption
conditions. The evaluation of the adsorption kinetics, isotherm, and thermodynamics
was deeply investigated. The results showed the adsorptive properties of the
NH2-NMPs were highly pH dependent. Adsorption of Cr(VI) reached equilibrium
within 30 min. The data of adsorption kinetics obeyed pseudo-second-order rate
mechanism well. The adsorption data for Cr(VI) onto NH2-NMPs were well fitted to
the Langmuir isotherm. The maximum adsorption capacities (q (m)) of the
NH2-NMPs to Cr(VI) were 136.98, 149.25, 204.08, 370.37 mg g-1, for EDA-NMPs,
DETA-NMPs, TETA-NMPs, and TEPA-NMPs, respectively. Thermodynamic
parameters like ΔH (theta), ΔS (theta), and ΔG (theta) for the adsorption of Cr(VI)
onto the NH2-NMPs have been estimated, which suggested that the adsorption
processes of Cr(VI) onto the NH2-NMPs were endothermic and entropy favored in
nature. The adsorption mechanism studies showed that the adsorption of Cr(VI) onto
the NH2-NMPs could be related with electrostatic attraction, ion exchange, and
coordination interactions.

supplementation and risk for perinatal maternal depression. Journal of
Maternal-Fetal & Neonatal Medicine, 24 (5), 680-686.
Abstract: Objective. A systematic review was conducted to assess the possible
association between omega-3 polyunsaturated fatty acid (PUFA) supplementation
and intake in the perinatal period and the risk of maternal perinatal depression.
Methods. Two PUBMED searches and a BIOSIS Preview, a Web of Science and a
PsychInfo search were conducted with the search terms ‘DHA, pregnancy and
depression’ and ‘omega-3 fatty acids, pregnancy and depression’. Results. Ten
articles - three longitudinal cohort studies, five randomized controlled trials and two
pilot trials-that met selection criteria were reviewed. Six found no association, two
found mixed results, and two found a positive association between omega-3 PUFAs
and reduced incidence of maternal perinatal depression. The heterogeneity of results
can be explained by dissimilar study designs, including differences in study duration,
time period of measurement and number of participants, and in varied dosages and
types of supplemental PUFAs. Some of the larger studies and those that found a
positive effect were more likely to be using higher doses, close to 2 g of
docosahexaeonic acid (DHA) + eicosapentaenoic acid (EPA), and began the
supplementation earlier in pregnancy. Conclusions. Future RCTs to investigate the
role of PUFA supplementation and risk for maternal perinatal depression should
begin supplementation early in pregnancy and use a dosage closer to 2 g of
DHA+EPA. Depression should also be measured using a diagnostic interview
schedule in addition to a screener.

Abstract: We consider the local equivalence problem for the class of linear second-order

pseudo-group of contact transformations. É. Cartan’s method is used for finding the
Maurer-Cartan forms for symmetry groups of equations from the class and
computing structure equations and complete sets of differential invariants for these
groups. The solution of the equivalence problem is formulated in terms of these
differential invariants.

Abstract: The effects of water quality during immature development on the vector
competence of adult female Culex tarsalis Coquillett for western equine
encephalomyelitis (WEE) and St. Louis encephalitis (SLE) viruses was evaluated
during 6 field and 4 laboratory experiments. Immatures of the Bakersfield Field
Station laboratory strain and the F1 progeny of field-collected females were reared in
the field or laboratory and then infected by feeding on pledgets, after which remnants
(head, thorax, abdomen), legs, and salivary secretions were tested for WEE or SLE
virus to estimate infection, dissemination, and transmission rates, respectively.
Although the salt content of the 6 larval habitats varied markedly (range, alkalinity
160-1, 310 ppm CaCO3, conductivity 460-7, 600 microns hos/cm, chlorides 22-1,
560 ppm) and significantly altered immature survival, development time, and female
body size (wing length), consistent changes in infection, dissemination, or
transmission rates were not observed. Susceptibility (ID50) to WEE virus in field
strains decreased as a linear function of developmental time, with populations from a
dry alkali lake bed (Goose Lake) least susceptible. Three subsequent laboratory
experiments that tested the effects of rearing immatures in dilution series of water
from Goose Lake failed to produce consistent within or among experiment patterns
in vector competence. A 4th laboratory experiment tested changes in NaCl
concentration with negative results. Changes in female size was not related to vector
competence. These and previous temperature studies indicated that temporal changes
288
in vector competence observed within and among field populations probably were
related to intrinsic genetic factors and were not related directly to extrinsic factors in
the immature aquatic environment.

on the troubled question of authorship. Journal of Medical Ethics, 26 (6), 422-426.
Full Text: J\J Med Eth26, 422.pdf
Abstract: The research assessment exercise (RAE) forms the basis for determining the
funding of higher education institutions in the UK. Monies are distributed according
to a range of performance criteria, the most important of which is “research outputs”.
Problems to do with publication misconduct, and in particular, issues of justice in
attributing authorship, are endemic within the research community. It is here argued
that the research assessment exercise currently makes no explicit attempt to address
these concerns, and indeed, by focusing attention on research outputs, may actually
be fostering such ethical problems.

Abstract: Objectives: To assess the knowledge and behaviour of researchers regarding
criteria for authorship, and the practices of ghost and gift authorship. Design:
Semidirective interviews of senior clinical researchers. Setting: University hospital.
Participants: Thirty-nine main investigators of clinical research programmes. Main
measurements: Awareness and use of International Committee of Medical Journal
Editors (ICMJE) criteria for authorship, and perceptions about ghost and gift
authorship. Results: A total of 48 protocols submitted by 42 principal investigators
between 1994 and 1996 were identified. Thirty- nine investigators were contacted;
37 (one of whom delegated a co-author) were interviewed between May 2002 and
290
March 2003. Two co-authors of two principal investigators were also interviewed. In
all, 42 studies were represented. The interviews lasted for 40 - 90 minutes and were
conducted with openness and respect for confidentiality. The choice of names of
co-authors did not follow the ICMJE recommendations. Half of the respondents
stated they were aware of criteria for authorship and knew of ICMJE, but most of
them did not cite any of the ICMJE criteria among those they applied in deciding
authorship. Most of them disagreed with the obligation to meet the three criteria
justifying co-authorship because they found these too rigid and inapplicable. Gift
authorship was a common practice; 59% of the respondents had been a recipient of
gift authorship. Twenty-five (64%) were aware of ghost authorship and the majority
considered it questionable and blameworthy. Conclusions: The ICMJE criteria were
ignored by clinicians at a university hospital. Ghost and gift authorship were frequent
among them. There is a need for French guidelines for authorship to be prepared and
implemented.

Abstract: Objective: To analyse the time variation of topics in bioethical publications as
a proxy of the relative importance. Methods: We searched the Medline database for
bioethics publications using the words “ethics or bioethics”, and for 360 specific
topics publications, associating Medical Subject Heading topic descriptors to those
words. We calculated the ratio of bioethics publications to the total publications of
Medline, and the ratio of each topic publications to the total bioethics publications,
for five-year intervals, from 1970 to 2004. We calculated the time variation of ratios,
dividing the difference between the highest and lowest ratio of each topic by its
highest ratio. Four topics were described, selected to illustrate different patterns of
variation: “Induced Abortion”, “Conflict of Interest”, “Acquired Immunodeficiency
Syndrome”, “Medical Education.” Results: The ratio of bioethics publications to
total Medline publications increased from 0.003 to 0.012. The variation of the topic’s
ratios was higher than 0.7 for 68% of the topics. The Induced Abortion ratios
decreased from 0.12 to 0.02. Conflict of Interest ratios increased from zero to 0.07.
The Acquired Immunodeficiency Syndrome ratios were nearly zero in the first three
intervals, had a peak of 0.06 during 1985-9, followed by a decrease to 0.01. Medical
Education ratios varied few, from 0.04 to 0.03. Conclusions: There was an increase
of bioethical publications in the Medline database. The topics in bioethics literature
have an important time variation. Some factors were suggested to explain this
variation: current legal cases, resolution of the issue, saturation of a discussion and
291
epidemiologic importance.

with dementia or in terminally ill patients were sanctity of life, considering artificial
food and fluid administration as basic nursing care, and giving reliable nutrition,
hydration or medication. An explicit counter-argument was the high cost of treatment.
Arguments used by opponents and proponents were quality of life and dignified
death. The arguments were not strikingly different for the two patient populations. It
turned out that the nurses’ ethical arguments remarkably reflected the current ethical
debate. But some of their clinical presuppositions contradicted current clinical
evidence. Conclusion: The interaction between clinical facts and ethical reflections
makes the findings of this review extremely relevant for clinical ethics. A large need
exists to clearly communicate to nurses the latest clinical evidence and the main
results of ongoing ethical debates.

Abstract: Background: Breaches of publication ethics such as plagiarism, data
fabrication and redundant publication are recognised as forms of research
292
misconduct that can undermine the scientific literature. We surveyed journal editors
to determine their views about a range of publication ethics issues. Methods:
Questionnaire sent to 524 editors-in-chief of Wiley-Blackwell science journals
asking about the severity and frequency of 16 ethical issues at their journals, their
confidence in handling such issues, and their awareness and use of guidelines.
Results: Responses were obtained from 231 editors (44%), of whom 48% edited
healthcare journals. The general level of concern about the 16 issues was low, with
mean severity scores of <1 (on a scale of 0-3) for all but one. The issue of greatest
concern (mean score 1.19) was redundant publication. Most editors felt confident in
handling the issues, with <15% feeling “not at all confident” for all but one of the
issues (gift authorship, 22% not confident). Most editors believed such problems
occurred less than once a year and >20% of the editors stated that 12 of the 16 items
never occurred at their journal. However, 13%-47% did not know the frequency of
the problems. Awareness and use of guidelines was generally low. Most editors were
unaware of all except other journals’ instructions. Conclusions: Most editors of
science journals seem not very concerned about publication ethics and believe that
misconduct occurs only rarely in their journals. Many editors are unfamiliar with
available guidelines but would welcome more guidance or training.

to doctoral students in Sweden. Journal of Medical Ethics, 36 (5), 315-318.

Abstract: ‘Scientific dishonesty’ implies the fabrication, falsification or plagiarism in
proposing, performing or reviewing research or in reporting research results. A
questionnaire was given to postgraduate students at the medical faculties in Sweden
who attended a course in research ethics during the academic year 2008/2009 and
58% answered (range 29%-100%). Less than one-third of the respondents wrote that
they had heard about scientific dishonesty in the previous 12 months. Pressure,
concerning in what order the author should be mentioned, was reported by about 1 in
10 students. We suggest that all departments conducting research should have a
written policy about acceptable research behaviour and that all doctoral students
should be informed of the content of this policy. Participants in the research groups
concerned should also be required to analyse published articles about scientific
dishonesty and critically discuss what could be done about unethical conduct.

Abstract: Objectives To investigate high school cheating experiences and attitudes
towards academic misconduct of freshmen at all four medical schools in Croatia, as a
post-communist country in transition, with intention of raising awareness of
academic (dis) honesty. Design and method Students were given an anonymous
questionnaire containing 22 questions on the atmosphere of integrity at their high
school, self-reported educational dishonesty, their evaluation of cheating behaviour,
and on their expectations about the atmosphere of integrity at their university. Setting
All schools of medicine of Croatian universities (Zagreb, Rijeka, Split and Osijek).
Main measures Descriptive statistics and differences in students’ self-reported
educational dishonesty, perception of cheating behaviour, and perception of the high
school integrity atmosphere. Results Of the 761 freshmen attending the four medical
schools, 508 (67%) completed the questionnaire: 481 Croatian and 27 international
students. Of the Croatian respondents, almost all (> 99%) self-reported engaging in
at least one behaviour of educational dishonesty, and 78% of respondents admitted to
having frequently cheated in at least one form of assessed academic misconduct.
Only three students admitted to having reported another student for cheating. For
most of the questions, there was no significant difference in the responses among
Croatian students. However, significant differences were found in most responses
between Croatian students and their international counterparts, who were
significantly less likely to engage in dishonest behaviours. No individual factor was
found to correlate with the incidence of self-admitted dishonest behaviour. Frequent
cheaters evaluated academic dishonesty significantly more leniently than those who
did not cheat. Conclusion Academic dishonesty of university students does not begin
in higher education; students come to medical schools ready to cheat.

fraud increasing? Journal of Medical Ethics, 37 (4), 249-253.
Full Text: 2011\J Med Eth37, 249.pdf
Abstract: Background Scientific papers are retracted for many reasons including fraud
(data fabrication or falsification) or error (plagiarism, scientific mistake, ethical
problems). Growing attention to fraud in the lay press suggests that the incidence of
fraud is increasing. Methods The reasons for retracting 742 English language
research papers retracted from the PubMed database between 2000 and 2010 were
evaluated. Reasons for retraction were initially dichotomised as fraud or error and
then analysed to determine specific reasons for retraction. Results Error was more
294
common than fraud (73.5% of papers were retracted for error (or an undisclosed
reason) vs 26.6% retracted for fraud). Eight reasons for retraction were identified; the
most common reason was scientific mistake in 234 papers (31.5%), but 134 papers
(18.1%) were retracted for ambiguous reasons. Fabrication (including data
plagiarism) was more common than text plagiarism. Total papers retracted per year
have increased sharply over the decade (r=0.96; p < 0.001), as have retractions
specifically for fraud (r=0.89; p < 0.001). Journals now reach farther back in time to
retract, both for fraud (r=0.87; p < 0.001) and for scientific mistakes (r=0.95; p <
0.001). Journals often fail to alert the naive reader; 31.8% of retracted papers were
not noted as retracted in any way. Conclusions Levels of misconduct appear to be
higher than in the past. This may reflect either a real increase in the incidence of
fraud or a greater effort on the part of journals to police the literature. However,
research bias is rarely cited as a reason for retraction.

Full Text: 1999\J Med Int Res1, e1.pdf
ABSTRACT: Background: The Internet offers a great amount of health related websites,
but concern has been raised about their reliability. Several subjective evaluation
criteria and websites rating systems have been proposed as a help for the Internet
users to distinguish among web resources with different quality, but their efficacy
has not been proven. Objective: To evaluate the agreement of a subset of Internet
rating systems editorial boards regarding their evaluations of a sample of pediatric
websites. To evaluate certain websites characteristics as possible quality indicators
for pediatric websites. Methods: Comparative survey of the results of systematic
evaluations of the contents and formal aspects of a sample of pediatric websites, with
the number of daily visits to those websites, the time since their last update, the
impact factor of their authors or editors, and the number of websites linked to them.
Results: 363 websites were compiled from eight rating systems. Only 25 were
indexed and evaluated by at least two rating systems. This subset included more
updated and more linked websites. There was no correlation among the results of the
evaluation of these 25 websites by the rating systems. The number of inbound links
to the websites significantly correlated with their updating frequency (p<.001), with
the number of daily visits (p=.005), and with the results of their evaluation by the
largest rating system, HealthAtoZ (p<.001). The websites updating frequency also
significantly correlated with the results of the websites evaluation by HealthAtoZ,
both about their contents (p=.001) and their total values (p<.05). The number of daily
297
visits significantly correlated (p<.05) with the results of the evaluations by Medical
Matrix. Conclusions: Some websites characteristics as the number of daily visits,
their updating frequency and, overall, the number of websites linked to them,
correlate with their evaluation by some of the largest rating systems on the Internet,
what means that certain indexes obtained from the usage analysis of pediatric
websites could be used as quality indicators. On the other hand, the citation analysis
on the Web by the quantification of inbound links to medical websites could be an
objective and feasible tool in rating great amounts of websites.

Abstract: The rapid growth in the number of health care related web sites necessitates
that medical librarians be able to evaluate the quality of the web sites. By analysing

schools, this study used the citation analysis method. What was found with this
bibliometric approach was a set of 78 most highly cited WWW sites out of thousands
of cited links. The identification of the current, core section of health sciences related
web sites with a bibliometric method gives librarians and information scientists
another approach for evaluating web sites.

review of published definitions. Journal of Medical Internet Research, 7 (1), Article
Number: e1.
Full Text: 2005\J Med Int Res7, e1.pdf
Abstract: Context: The term eHealth is widely used by many individuals, academic
institutions, professional bodies, and funding organizations. It has become an
accepted neologism despite the lack of an agreed-upon clear or precise definition.
We believe that communication among the many individuals and organizations that
use the term could be improved by comprehensive data about the range of meanings
encompassed by the term. Objective: To report the results of a systematic review of
published, suggested, or proposed definitions of eHealth. Data Sources: Using the
search query string “eHealth” OR “e-Health” OR “electronic health”, we searched
the following databases: MEDLINE and PreMEDLINE (1966-June 2004), EMBASE
(1980-May 2004), International Pharmaceutical Abstracts (1970-May 2004), Web of
Science (all years), Information Sciences Abstracts (1966-May 2004), Library
Information Sciences Abstracts (1969-May 2004), and Wilson Business Abstracts
(1982-March 2004). In addition, we searched dictionaries and an Internet search
engine. Study Selection: We included any source published in either print format or
298
on the Internet, available in English, and containing text that defines or attempts to
define eHealth in explicit terms. Two of us independently reviewed titles and
abstracts of citations identified in the bibliographic databases and Internet search,
reaching consensus on relevance by discussion. Data Extraction: We retrieved
relevant reports, articles, references, letters, and websites containing definitions of
eHealth. Two of us qualitatively analyzed the definitions and coded them for content,
emerging themes, patterns, and novel ideas. Data Synthesis: The 51 unique
definitions that we retrieved showed a wide range of themes, but no clear consensus
about the meaning of the term eHealth. We identified 2 universal themes (health and
technology) and 6 less general (commerce, activities, stakeholders, outcomes, place,
and perspectives). Conclusions: The widespread use of the term eHealth suggests
that it is an important concept, and that there is a tacit understanding of its meaning.
This compendium of proposed definitions may improve communication among the
many individuals and organizations that use the term.

Research, 8 (2), Article Number: e8.
Full Text: 2006\J Med Int Res8, e8.pdf
Abstract: A study published today in PLoS Biology provides robust evidence that
open-access articles are more immediately recognized and cited than non-OA articles.
This editorial provides some additional follow up data from the most recent analysis
of the same cohort in April 2006, 17 to 21 months after publication. These data
suggest that the citation gap between open access and non-open access papers
continues to widen. I conclude with the observation that the “open access advantage”
has at least three components: (1) a citation count advantage (as a metric for
knowledge uptake within the scientific community), (2) an end user uptake
advantage, and (3) a cross-discipline fertilization advantage. More research is needed,
and JMIR is inviting research on all aspects of open access. As the advantages for
publishing open access from a researchers’ point of view become increasingly clear,
questions around the sustainability of open access joumals remain. This journal is a
living example that “lean publishing” models can create successful open access
journals. Open source tools which have been developed by the Public Knowledge
Project at the University of British Columbia with contributions from the
Epublishing & Open Access group at the Centre for Global eHealth Innovation in
Toronto are an alternative to hosting joumals on commercial open access publisher
299
sites.

Abstract: Background: Nowadays people are extensively encouraged to become more
physically active. The Internet has been brought forward as an effective tool to
change physical activity behavior. However, little is known about the evidence
regarding such Internet-based interventions. Objective: The aim of the study was to
systematically a assess the methodological quality and the effectiveness of
interventions designed to promote physical activity by means of the Internet as
evaluated by randomized controlled trials. Methods: A literature search was
conducted up to July 2006 using the databases PUBMED, Web of Science,
EMBASE PsychINFO, and Cochrane Library. Only randomized controlled trials
describing the effectiveness of an Internet-based intervention, with the promotion of
physical activity among adults being one of its major goals, were included. Data
extracted included source and year of publication, country of origin, targeted health
behaviors, participants’ characteristics, characteristics of the intervention, and
effectiveness data. In addition, the methodological quality was assessed. Results: The
literature search resulted in 10 eligible studies of which five met at least nine out of
13 general methodological criteria. The majority of the interventions were tailored to
the characteristics of the participants and used interactive self-monitoring and
feedback tools. Six studies used one or more theoretical models to compose the
contents of the interventions. One study used an objective measure to assess the
amount of physical activity (activity monitor), and six studies used multiple
subjective measures of physical activity. Furthermore, FONT half of the studies
employed SIZE measures of physical fitness M other than physical activity. FA I In
three studies, an Internet-based physical activity intervention was compared
DONATION with a waiting list group. of Support these three studies, two reported a
significantly greater improvement in physical activity levels in the Internet-based
intervention than in the control group. Seven studies compared two types of
Internet-based physical activity interventions in which the main difference was either
the intensity of contact between the participants and supervisors (4 studies) or the
type of treatment procedures applied (3 studies). In one of these studies, a significant
effect in (sic) with more supervisor contact was seen. Conclusions: There is
indicative evidence that Internet-based physical activity interventions are more
300
effective than a waiting list strategy. The added value of specific components of
Internet-based physical activity interventions such as increased supervisor contact,
tailored information, or theoretical fidelity, remains to be established.
Methodological quality as well as the type of physical activity outcome measure
varied, stressing the need for standardization of these measures.

to diabetes care: A systematic literature review. Journal of Medical Internet

Full Text: 2007\J Med Int Res9, e37.pdf
Abstract: Background: A systematic literature review was carried out to study the
benefits of teleconsultation and videoconferencing on the multifaceted process of
diabetes care. Previous reviews focused primarily on usability of technology and
considered mainly one-sided interventions. Objective: The objective was to
determine the benefits and deficiencies of teleconsultation and videoconferencing
regarding clinical, behavioral, and care coordination outcomes of diabetes care.
Methods: Electronic databases (MEDLINE, PiCarta, PsycINFO, ScienceDirect,
Telemedicine Information Exchange, ISI Web of Science, Google Scholar) were
searched for relevant publications. The contribution to diabetes care was examined
for clinical outcomes (eg, HbA(1c), blood pressure, quality of life), behavioral
outcomes (patient-caregiver interaction, self-care), and care coordination outcomes
(usability of technology, cost-effectiveness, transparency of guidelines, equity of
care access). Randomized controlled trials (RCTs) with HbA(1c) as an outcome were
pooled using standard meta-analytical methods. Results: of 852 publications
identified, 39 met the inclusion criteria for electronic communication between
(groups of) caregivers and patients with type 1, type 2, or gestational diabetes.
Studies that evaluated teleconsultation or videoconferencing not particularly aimed at
diabetes were excluded, as were those that described interventions aimed solely at
clinical improvements (eg, HbA(1c)). There were 22 interventions related to
teleconsultation, 13 to videoconferencing, and 4 to combined teleconsultation and
videoconferencing. The heterogeneous nature of the identified videoconferencing
301
studies did not permit a formal meta-analysis. Pooled results from the six RCTs of
the identified teleconsultation studies did not show a significant reduction in HbA(1c)
(0.03%, 95% CI = -0.31% to 0.24%) compared to usual care. There was no
significant statistical heterogeneity among the pooled RCTs (X(7)(2)=7.99, P=.33). It
can be concluded that in the period under review (1994-2006) 39 studies had a scope
broader than clinical outcomes and involved interventions allowing patient-caregiver
interaction. Most of the reported improvements concerned satisfaction with
technology (26/39 studies), improved metabolic control (21/39), and cost reductions
(16/39). Improvements in quality of life (6/39 studies), transparency (5/39), and
better access to care (4/39) were hardly observed. Teleconsultation programs
involving daily monitoring of clinical data, education, and personal feedback proved
to be most successful in realizing behavioral change and reducing costs. The benefits
of videoconferencing were mainly related to its effects on socioeconomic factors
such as education and cost reduction, but also on monitoring disease. Additionally,
videoconferencing seemed to maintain quality of care while producing cost savings.
Conclusions: The selected studies suggest that both teleconsultation and
videoconferencing are practical, cost-effective, and reliable ways of delivering a
worthwhile health care service to diabetics. However, the diversity in study design
and reported findings makes a strong conclusion premature. To further the
contribution of technology to diabetes care, interactive systems should be developed
that integrate monitoring and personalized feedback functions.

? Abstract: Background: There has been a significant increase in the availability of
online programs for alcohol problems. A systematic review of the research evidence
underpinning these programs is timely. Objectives: Our objective was to review the
302
efficacy of online interventions for alcohol misuse. Systematic searches of
MEDLINE, PsycINFO, Web of Science, and Scopus were conducted for English
abstracts (excluding dissertations) published from 1998 onward. Search terms were:
(1) Internet, Web*; (2) online, computer*; (3) alcohol*; and (4) E\effect*, trial*,
random* (where * denotes a wildcard). Forward and backward searches from
identified papers were also conducted. Articles were included if (1) the primary
intervention was delivered and accessed via the Internet, (2) the intervention focused
on moderating or stopping alcohol consumption, and (3) the study was a randomized
controlled trial of an alcohol-related screen, assessment, or intervention. Results: The
literature search initially yielded 31 randomized controlled trials (RCTs), 17 of
which met inclusion criteria. of these 17 studies, 12 (70.6%) were conducted with
university students, and 11 (64.7%) specifically focused on at-risk, heavy, or binge
drinkers. Sample sizes ranged from 40 to 3216 (median 261), with 12 (70.6%)
studies predominantly involving brief personalized feedback interventions. Using
published data, effect sizes could be extracted from 8 of the 17 studies. In relation to
alcohol units per week or month and based on 5 RCTs where a measure of alcohol
units per week or month could be extracted, differential effect sizes to posttreatment
ranged from 0.02 to 0.81 (mean 0.42, median 0.54). Pre-post effect sizes for brief
personalized feedback interventions ranged from 0.02 to 0.81, and in 2 multi-session
modularized interventions, a pre-post effect size of 0.56 was obtained in both.
Pre-post differential effect sizes for peak blood alcohol concentrations (BAC) ranged
from 0.22 to 0.88, with a mean effect size of 0.66. Conclusions: The available
evidence suggests that users can benefit from online alcohol interventions and that
this approach could be particularly useful for groups less likely to access traditional
alcohol-related services, such as women, young people, and at-risk users. However,
caution should be exercised given the limited number of studies allowing extraction
of effect sizes, the heterogeneity of outcome measures and follow-up periods, and the
large proportion of student-based studies. More extensive RCTs in community
samples are required to better understand the efficacy of specific online alcohol
approaches, program dosage, the additive effect of telephone or face-to-face
interventions, and effective strategies for their dissemination and marketing.

Abstract: Background: The Internet has become a popular medium for the delivery of
tailored healthy lifestyle promoting interventions. The actual reach of
Internet-delivered interventions seems, however, lower than expected, and attrition
from interventions is generally high. Characteristics of an intervention, such as
personally tailored feedback and goal setting, are thought to be among the important
factors related to of use of and exposure to interventions. However, there is no
systematic overview of which characteristics of Internet-delivered interventions may
be related to more exposure. Objective: The present study aims to identify (1) which
potentially exposure-promoting methods and strategies are used in existing Internet
interventions, (2) which objective outcome measures are used to measure exposure to
Internet interventions, and (3) which potentially exposure-promoting methods and
strategies are associated with better exposure. Methods: A systematic review of the
literature was conducted based on the Cochrane guidelines. Papers published
between 1995 and 2009 were searched in the PUBMED, PsycINFO, and Web of
Science databases. In total, 64 studies were included that reported objective exposure
measures such as completion of an initial visit, number of log-ins, and time spent on
the website. Information about intervention-related characteristics (ie, interactive
behavior change strategies, interactive elements for fun, peer or counsel support,
email/phone contact, and regular updates of the website) that could potentially
contribute to better exposure and objective exposure outcomes were abstracted from
the studies and qualitative systematic descriptive analyses were performed. Results:
The results showed that a large variety of behavior change techniques and other
exposure-promoting elements were used in the interventions and that these methods
and strategies varied for the various lifestyle behaviors. Feedback, interactive
elements, and email/phone contact were used most often. In addition, there was much
variety and a lack of consistency in the exposure measures that were reported. of all
the categories of intervention characteristics that may be associated with better
exposure, there were indications that peer and counselor support result in a longer
website visit and that email/phone contact and updates of the website result in more
log-ins. Conclusions: Results of this qualitative systematic review indicate that of all
intervention characteristics that could potentially enhance exposure, only peer
support, counselor support, email/phone contact with visitors, and updates of the
intervention website were related to better exposure. The diversity of intervention
304
methods used and the inconsistency in the report of exposure measures prevented us
from drawing firmer conclusions. More research is needed to identify whether other
characteristics of Internet interventions are associated with greater exposure.

methodological quality of ICT-based PA interventions for children and adolescents
based on evidence from randomized controlled trials. Methods: Electronic databases
Medline, PsycInfo, CINAHL, and Web of Science were searched to retrieve English
language articles published in international academic peer-reviewed journals from
January 1, 1997, through December 31, 2009. Included were articles that provided
descriptions of interventions designed to improve PA-related cognitive, psychosocial,
and behavioral outcomes and that used randomized controlled trial design, included
only children (6-12 years old) and adolescents (13-18 years old) in both intervention
and control groups, and employed Internet, email, and, or short message services
(SMS, also known as text messaging) as one or more major or assistive modes to
deliver the intervention. Results: In total, 9 studies were analyzed in the present
review. All studies were published after 2000 and conducted in Western countries. of
the 9 studies, 7 demonstrated positive and significant within-group differences in at
least one psychosocial or behavioral PA outcome. In all, 3 studies reported positive
and significant between-group differences favoring the ICT group. When
between-group differences were compared across studies, effect sizes were small in 6
studies and large in 3 studies. With respect to methodological quality, 7 of the 9
studies had good methodological quality. Failure to report allocation concealment,
305
blinding to outcome assessment, and lack of long-term follow-up were the criteria
met by the fewest studies. In addition, 5 studies measured the intervention exposure
rate and only 1 study employed objective measures to record data. Conclusion: The
present review provides evidence supporting the positive effects of ICTs in PA
interventions for children and adolescents, especially when used with other delivery
approaches (ie, face-to-face). Because ICT delivery approaches are often mixed with
other approaches and these studies sometimes lack a comparable control group,
additional research is needed to establish the true independent effects of ICT as an
intervention delivery mode. Although two-thirds of the studies demonstrated
satisfactory methodological quality, several quality criteria should be considered in
future studies: clear descriptions of allocation concealment and blinding of outcome
assessment, extension of intervention duration, and employment of objective
measures in intervention exposure rate. Due to the small number of studies that met
inclusion criteria and the lack of consistent evidence, researchers should be cautious
when interpreting the findings of the present review.

Abstract: Objectives: This study compared the mapping of natural language patron
terms to the Medical Subject Headings (MeSH) across six MeSH interfaces for the
MEDLINE database. Methods: Test data were obtained from search requests
submitted by patrons to the Library of the Health Sciences, University of Illinois at
Chicago, over a nine-month period. Search request statements were parsed into
separate terms or phrases. Using print sources from the National Library of Medicine,
Each parsed patron term was assigned corresponding MeSH terms, Each patron term
was entered into each of the selected interfaces to determine how effectively they
mapped to MeSH. Data were collected for mapping success, accessibility of MeSH
term within mapped list, and total number of MeSH choices within each list. Results:
The selected MEDLINE interfaces do not map the same patron term in the same way,
nor do they consistently lead to what is considered the appropriate MeSH term.

Abstract: Objectives: The study sought to investigate how Spanish names are handled
by national and international databases and to identify mistakes that can undermine
the usefulness of these databases for locating and retrieving works by Spanish
authors.
Methods: The authors sampled 172 articles published by authors from the University of
Granada Medical School between 1987 and 1996 and analyzed the variations in how
each of their names was indexed in Science Citation Index (SCI), MEDLINE, and
indice M6dico Espanol (IME). The number and types of variants that appeared for
each author’s name were recorded and compared across databases to identify
inconsistencies in indexing practices. We analyzed the relationship between
variability (number of variants of an author’s name) and productivity (number of
items the name was associated with as an author), the consequences for retrieval of
information, and the most frequent indexing structures used for Spanish names.
Results: The proportion of authors who appeared under more then one name was 48.1%
in SCI, 50.7% in MEDLINE, and 69.0% in IME. Productivity correlated directly
with variability: more than 50% of the authors listed on five to ten items appeared
under more than one name in any given database, and close to 100% of the authors
listed on more than ten items appeared under two or more variants. Productivity
correlated inversely with retrievability: as the number of variants for a name
increased, the number of items retrieved under each variant decreased. For the most
highly productive authors, the number of items retrieved under each variant tended
toward one. The most frequent indexing methods varied between databases. In
MEDLINE and IME, names were indexed correctly as “first surname second
surname, first name initial middle name initial” (if present) in 41.7% and 49.5% of
the records, respectively. However, in SCI, the most frequent method was “first
surname, first name initial second name initial” (48.0% of the records) and first
surname and second surname run together, first name initial (18.3%).
Conclusions: Retrievability on the basis of author’s name was poor in all three
databases. Each database uses accurate indexing methods, but these methods fail to
result in consistency or coherence for specific’. entries. The likely causes of
inconsistency are: (1) use by authors of variants of their names during their
publication careers, (2) lack of authority control in all three databases, (3) the use of
308
an inappropriate indexing method for Spanish names in SCI, (4) authors’ inconsistent
behaviors, and (5) possible editorial interventions by some journals. We offer some
suggestions as to how to avert the proliferation of author name variants in the
databases.

Abstract: Interest in the role of qualitative research in evidence-based health care is
growing. However, the methods currently used to identify quantitative research do
not translate easily to qualitative research. This paper highlights some of the
difficulties during searches of electronic databases for qualitative research. These
difficulties relate to the descriptive nature of the titles used in some qualitative
studies, the variable information provided in abstracts, and the differences in the
indexing of these studies across databases.

Abstract: Objectives: Impact Factor, an index based on the frequency with which a
journal’s articles are cited in scientific publications, is a putative marker of journal
quality. However, empiric studies on impact factor’s validity as an indicator of
quality are lacking. The authors assessed the validity of impact factor as a measure of
quality for general medical journals by testing its association with journal quality as
309
rated by clinical practitioners and researchers.
Methods: We surveyed physicians specializing in internal medicine in the United States,
randomly sampled from the American Medical Associations Physician Masterfile
(practitioner group, n = 113) and from a list of graduates from a national postdoctoral
training program in clinical and health services research (research group, n = 151).
Respondents rated the quality of nine general medical journals, and we assessed the
correlation between these ratings and the journals’ impact factors.
Results: The correlation between impact factor and physicians’ ratings of journal quality
was strong (r2 = 0.82, P = 0.001). The correlation was higher for the research group
(r2 = 0.83, P = 0.001) than for the practitioner group (r2 = 0.62, P = 0.01).
Conclusions: Impact Factor may be a reasonable indicator of quality for general medical
journals.

Abstract: Objective: This study presents the results of an author co-citation analysis of
the interdisciplinary field of medical informatics.
Methods: An author co-citation analysis was conducted for the years 1994 to 1998,
using the fifty most-cited American College of Medical Informatics fellows as an
author population. Co-citation data were calculated for every author pair, and
multivariate analyses were performed to ultimately show the relationships among all
authors. A multidimensional map was created, wherein each author is represented as
a point, and the proximity of these points reflects the relationships of authors as
perceived by multiple citers.
Results and Conclusion: The results from this analysis provide one perspective of the
field of medical informatics and are used to suggest future research directions to
address issues related to better understanding of communication and social networks
in the field to inform better provision of information services.

Abstract: This paper describes a citation analysis of the literature of clinical laboratory
science (medical technology), conducted as part of a project of the Nursing and
Allied Health Resources Section of the Medical Library Association. Three source
journals widely read by those in the field were identified, from which cited
references were collected for a three-year period. Analysis of the references showed
that journals were the predominant format of literature cited and the majority of the
references were from the last eleven years. Applying Bradford’s Law of Scattering to
310
the list of journals cited, three zones were created, each producing approximately one
third of the cited references. Thirteen journals were in the first zone, eighty-one in
the second, and 849 in the third. A similar list of journals cited was created for four
specialty areas in the field: chemistry, hematology, immunohematology, and
microbiology. In comparing the indexing coverage of the Zone 1 and 2 journals by
four major databases, MEDLINE provided the most comprehensive coverage, while
the Cumulative Index to Nursing and Allied Health Literature was the only database
that provided complete coverage of the three source journals. However, to obtain
complete coverage of the field, it is essential to search multiple databases.

veterinary medical journals. Journal of the Medical Library Association, 91 (4),
434-441.
Full Text: J\J Med Lib Ass91, 434.pdf
Abstract: Objectives: Grey literature has been perceived by many as belonging to the
primary sources of information and has become an accepted method of
nonconventional communication in the sciences and medicine. Since little is known
about the use and nature of grey literature in veterinary medicine, a systematic study
was done to analyze and characterize the bibliographic citations appearing in twelve
core veterinary journals.
Methods: Citations from 2,159 articles published in twelve core veterinary journals in
2000 were analyzed to determine the portion of citations from grey literature. Those
citations were further analyzed and categorized according to the type of publication.
Results: Citation analysis yielded 55,823 citations, of which 3,564 (6.38%) were
considered to be grey literature. Four veterinary specialties, internal medicine,
pathology, theriogenology, and microbiology, accounted for 70% of the total number
of articles. Three small-animal clinical practice journals cited about 2.5-3% grey
literature, less than half that of journals with basic research orientations, where
results ranged from almost 6% to approximately 10% grey literature. Nearly 90% of
the grey literature appeared as conferences, government publications, and corporate
organization literature.
Conclusions: The results corroborate other reported research that the incidence of grey
literature is lower in medicine and biology than in some other fields, such as
aeronautics and agriculture. As in other fields, use of the Internet and the Web has
greatly expanded the communication process among veterinary professionals. The
appearance of closed community email forums and specialized discussion groups
within the veterinary profession is an example of what could become a new kind of
grey literature.

Abstract: Public interest in issues concerning the maintenance of high ethical standards
in the conduct of scientific research and its publication has been increasing. Some of
the developments in these issues as reflected in the publication of the medical
literature are traced here. This paper attempts to determine whether public interest is
reflected in the specific requirements for authors for manuscript preparation as stated
in the “Instructions to Authors” for articles being prepared for submission to 124
“high-impact” journals. The instructions to authors of these journals were read on the
Web for references to ethical standards or requirements. The ethical issues that the
instructions most often covered were specifically related to the individual journal’s
publication requirements. The results suggest that while the editors and publishers of
the biomedical literature are concerned with promoting and protecting the rights of
the subjects of the experiments in the articles they publish, and while these concerns
are not yet paramount, they are evolving and growing.

Abstract: Purpose: The paper explores the current state of generalist search education in
library schools and considers that foundation in respect to the Medical Library
Association’s statement on expert searching. Setting, Subjects: Syllabi from courses
with significant searching components were examined from ten of the top library
schools, as determined by the US. News & World Report rankings. Methodology:
Mixed methods were used, but primarily quantitative bibliometric methods were
used. Results: The educational focus in these searching components was on
understanding the generalist searching resources and typical users and on performing
a reflective search through application of search strategies, controlled vocabulary,
and logic appropriate to the search tool. There is a growing emphasis on Web-based
search tools and a movement away from traditional set-based searching and toward
free-text search strategies. While a core set of authors is used in these courses, no
core set of readings is used. Discussion, Conclusion: While library schools provide a
strong foundation, future medical librarians still need to take courses that introduce
them to the resources, settings, and users associated with medical libraries. In
312
addition, as more emphasis is placed on Web-based search tools and free-text
searching, instructors of the specialist medical informatics courses will need to focus
on teaching traditional search methods appropriate for common tools in the medical
domain.

Abstract: Objective: Evidence-based medicine (EBM) is a significant issue and the
randomized controlled trial (RCT) literature plays a fundamental role in developing
EBM. This study investigates the features of RCT literature based on bibliometric
methods. Growth of the literature, publication types, languages, publication countries,
and research subjects are addressed. The distribution of journal articles was also
examined utilizing Bradford’s law and Bradford-Zipf’s law. Method: The MEDLINE
database was searched for articles indexed under the publication type “Randomized
Control Trial,” and articles retrieved were counted and analyzed using Microsoft
Access, Microsoft Excel, and PERL. Results: From 1990 to 2001, a total of 114,850
citations dealing with RCTs were retrieved. The literature growth rate, from 1965 to
2001, is steadily rising and follows an exponential model. Journal articles are the
predominant form of publication, and the multicenter study is extensively used.
English is the most commonly used language. Conclusions: Generally, RCTs are
found in publications concentrating on cardiovascular disease, cancer, asthma,
postoperative condition, health, and anesthetics. Zone analysis and graphical
formulation from Bradford’s law of scattering shows variations from the standard
Bradford model. Forty-two core journals were identified using Bradford’s law.

Abstract: Introduction: This project is a collaborative effort of the Task Force on
Mapping the Nursing Literature of the Nursing and Allied Health Resources Section
313
of the Medical Library Association. This overview summarizes eighteen studies
covering general nursing and sixteen specialties. Method: Following a common
protocol, citations from source journals were analyzed for a three-year period within
the years 1996 to 2000. Analysis included cited formats, age, and ranking of the
frequency of cited journal titles. Highly cited journals were analyzed for coverage in
twelve health sciences and academic databases. Results: journals were the most
frequently cited format, followed by books. More than 60% of the cited resources
were published in the previous seven years. Bradford’s law was validated, with a
small core of cited journals accounting for a third of the citations. Medical and
science databases provided the most comprehensive access for biomedical titles,
while CINAHL and PubMed provided the best access for nursing journals.
Discussion: Beyond a heavily cited core, nursing journal citations are widely
dispersed among a variety of sources and disciplines, with corresponding access via a
variety of bibliographic tools. Results underscore the interdisciplinary nature of the
nursing profession. Conclusion: For comprehensive searches, nurses need to search
multiple databases. Libraries need to provide access to databases’ beyond PubMed,
including CINAHL and academic databases. Database vendors should improve their
coverage of nursing, biomedical, and psychosocial titles identified in these studies.
Additional research is needed to update these studies and analyze nursing specialties
not covered.

Abstract: Objectives: As part of a project to map the literature of nursing, sponsored by
the Nursing and Allied Health Resources Section of the Medical Library Association,
this study identifies core journals cited by general or “popular” US nursing journals
and the indexing services that cover the cited journals.
Methods: Three journals were selected for analysis: American Journal of Nursing,
Nursing 96–98, and RN. The source journals were subjected to a citation analysis of
articles from 1996 to 1998, followed by an analysis of database access to the most
frequently cited journal titles.
Results: Cited formats included journals (63.7%), books (26.6%), government
documents (3.0%), Internet (0.5%), and miscellaneous (6.2%). Cited references were
relatively current; most (86.6%) were published in the current decade. One-third of
314
the citations were found in a core of 24 journal titles; one-third were dispersed
among a middle zone of 94 titles; and the remaining third were scattered in a larger
zone of 694 titles. Indexing coverage for the core titles was most comprehensive in
PubMed/MEDLINE, followed by CINAHL and Science Citation Index.
Conclusions: Results support the popular (not scholarly) nature of these titles. While not
a good source for original research, they fulfill a key role of disseminating nursing
knowledge with their relevantly current citations to a broad variety of sources.

Abstract: OBJECTIVES: The purpose of this study was to identify core journals in
home health nursing and to determine how well these journals were covered by
indexing and abstracting services. The study was part of the project for mapping the
nursing literature of the Medical Library Association’s Nursing and Allied Health
Resource Section. METHODS: A citation analysis of two core journals was done to
determine distribution of references by format types and age of citations and
dispersion of the literature, according to Bradford’s Law of Scattering. The analysis
of indexing coverage for Zone 1 and 2 was also provided. RESULTS: The study
showed that 64.2% of citations came from journals, versus 22.9% from books and
12.9% from other publications. PubMed/MEDLINE rated highest in average
indexing coverage of Zone 1 and 2 journals, followed by CINAHL. PsycINFO,
SocioAbstracts, and EBSCO Health Business FullTEXT showed practically no
coverage for the home health nursing literature. CONCLUSION: As expected,
journal articles were found to be the primary source for referencing and books, the
secondary source. In regard to bibliographic control, no databases provided full
coverage of the journals in the field of home health nursing. PubMed/MEDLINE and
CINAHL gave better results in combination, because CINAHL tended to cover more
nursing journals, while PubMed/MEDLINE did better with medical titles.

Abstract: Objectives: As part of a project to map the literature of nursing, sponsored by

this study identifies core journals cited in maternal-child/gynecologic nursing and the
315
indexing services that access the cited journals.
Methods: Three source journals were selected and subjected to a citation analysis of
articles from 1996 to 1998.
Results: Journals were the most frequently cited format (74.1%), followed by books
(19.7%), miscellaneous (4.2%), and government documents (1.9%). Bradford’s Law
of Scattering was applied to the results, ranking cited journal references in
descending order. One-third of the citations were found in a core of 14 journal titles;
one-third were dispersed among a middle zone of 100 titles; and the remaining third
were scattered in a larger zone of 1,194 titles. Indexing coverage for the core titles
was most comprehensive in PubMed/MEDLINE, followed by Science Citation Index
and CINAHL.
Conclusion: The core of journals cited in this nursing specialty revealed a large number
of medical titles, thus, the biomedical databases provide the best access. The
interdisciplinary nature of maternal-child/ gynecologic nursing topics dictates that
social sciences databases are an important adjunct. The study results will assist
librarians in collection development, provide end users with guidelines for selecting
databases, and influence database producers to consider extending coverage to
identified titles.

the Medical Library Association, 94 (2 Suppl), E65-E73.
Full Text: 2006\J Med Lib Ass94, E65.pdf
Abstract: Background: Medical-surgical or adult health nursing is a complex specialty
that requires a wide-ranging literature to inform its research and practice. Several
excellent qualitative aids exist for collection development for this field, but
quantitative studies are few. While one bibliometric study of journals exists, no
recent work had been done in this area.
Method: The Mapping the Literature of Nursing Project protocol was used. Four source
journals were selected, and a citation analysis of articles from 1996 to 1998 was
conducted.
Results: A list of the most frequently cited journals was created, using Bradford’s Law
of Scattering. The list demonstrates that 1.2% of the cited medical-surgical nursing
journals produced just over 33% of the citations. PubMed/MEDLINE, CINAHL, and
Science Citation Index provided the most complete indexing coverage of all of the
journals, with CINAHL providing the most complete coverage of nursing journals.
Books were the second-most cited format.
Conclusions: Citation analysis of journal articles is a useful aid for selecting journals for
medical-surgical nursing collections, but it did not prove to be as useful for selecting
materials in other formats. Indexes in addition to PubMed/MEDLINE are necessary
to provide access to the journal literature serving this specialty.

Full Text: 2006\J Med Lib Ass94, E74.pdf
Abstract: Objectives: A bibliometric investigation was done to identify characteristics
of the literature that nephrology nurses utilize. It is one component of a broader study,
“Mapping the Literature of Nursing,” by the Medical Library Association’s Nursing
and Allied Health Resources Section Task Force to Map the Literature of Nursing.
Methods: Following a standard protocol, this project utilized Bradford’s Law of
Scattering to analyze the literature of nephrology nursing. Citation analysis was done
on articles that were published from 1996 to 1998 in a source journal. Cited journal
titles were divided into three zones, and coverage in major article databases were
scored for Zones 1 and 2.
Results: During the three-year period, journals were the most frequently cited format
type. Eighty-one journals were cited in Zones 1 and 2. As Bradford’s Law of
Scattering predicted, a small number of the cited journals accounted for the most use.
Coverage is most comprehensive for cited journals in Science Citation Index,
PubMed/ MEDLINE, and EMBASE. When looking just at cited nursing journals,
CINAHL and PubMed/MEDLINE provide the best indexing coverage.
Conclusion: This study offers understanding of and insights into the types of
information that nephrology nurses use for research. It is a valuable tool for anyone
involved with providing nephrology nursing literature.

A study of the literature of nurse-midwifery reveals that the field is diverse,
including such topics as women’s health, obstetrics, gynecology, and parent-child
relations, in addition to the practice of nurse-midwifery itself. Journals were the most
heavily cited format, and analysis revealed that ten journals provided one-third of all
the references in the study. CONCLUSIONS: A combination of Science Citation
Index and Social Sciences Citation Index or PubMed/MEDLINE provided the best
overall coverage because of the field’s reliance on medical journals. CINAHL had
the most complete coverage for the nurse-midwifery journals as well as nursing
journals in general.

Abstrct: Objectives: As part of Phase I of a project to map the literature of nursing,
sponsored by the Nursing and Allied Health Resources Section of the Medical
Library Association, this study identifies the core literature cited in nursing
administration and the indexing services that provide access to the core journals. The
results of this study will assist librarians and end users searching for information
related to this nursing discipline, as well as database producers who might consider
adding specific titles to their indexing services.
Methods: Using the common methodology described in the overview article, five source
journals for nursing administration were identified and selected for citation analysis
over a three-year period, 1996 to 1998, to identify the most frequently cited titles
according to Bradford’s Law of Scattering. From this core of most productive journal
titles, the bibliographic databases that provide the best access to these titles were
identified.
Results: Results reveal that nursing administration literature relies most heavily on
journal articles and on those titles identified as core nursing administrative titles.
When the indexing coverage of nine services is compared, PubMed/MEDLINE and
CINAHL provide the most comprehensive coverage of this nursing discipline.
Conclusions: No one indexing service adequately covers this nursing discipline.
Researchers needing comprehensive coverage in this area must search more than one
database to effectively research their projects. While PubMed/MEDLINE and
CINAHL provide more coverage for this discipline than the other indexing services,
none is sufficiently broad in scope to provide indexing of nursing, health care
management, and medical literature in a single file. Nurse administrators using the
literature to research current work issues need to review not only the nursing titles
covered by CINAHL but should also include the major weekly medical titles, core
titles in health care administration, and general business sources if they wish to
adequately cover the many aspects of nursing administration.

Abstract: Objective: This study was part of the Medical Library Association’s Nursing
and Allied Health Resources Section’s project to map the nursing literature. It
318
identified core journals in nursing informatics and the journals referenced in them
and analyzed coverage of those journals in selected indexes.
Method: Five core journals were chosen and analyzed for 1996, 1997, and 1998. The
references in the core journal articles were examined for type and number of formats
cited during the selected time period. Bradford’s Law of Scattering divided the
journals into frequency zones.
Results: The time interval, 1990 to 1998, produced 71% of the references. Internet
references could not be tracked by date before 1990. Twelve journals were the most
productive, 119 journals were somewhat productive, and 897 journals were the least
productive. Journal of the American Medical Informatics Association was the most
prolific core journal. The 1998 journal references were compared in CINAHL,
PubMed/MEDLINE, Science Citation Index, and OCLC Article First.
PubMed/MEDLINE had the highest indexing score.

Full Text: 2006\J Med Lib Ass94, E99.pdf
Abstract: Objectives: Nursing case management provides a continuum of health care
services for defined groups of patients. Its literature is multidisciplinary, emphasizing
clinical specialties, case management methodology, and the health care system. This
study is part of a project to map the literature of nursing, sponsored by the Nursing
and Allied Health Resources Section of the Medical Library Association. The study
identifies core journals cited in case management literature and indexing services that
access those journals.
Methods: Three source journals were identified based on established criteria, and cited
references from each article published from 1997 to 1999 were analyzed.
Results: Nearly two-thirds of the cited references were from journals; others were from
books, monographs, reports, government documents, and the Internet. Cited journal
references were ranked in descending order, and Bradford’s Law of Scattering was
applied. The many journals constituting the top two zones reflect the diversity of this
field. Zone 1 included journals from nursing administration, case management,
general medicine, medical specialties, and social work. Two databases,
PubMed/MEDLINE and OCLC ArticleFirst, provided the best indexing coverage.
Conclusion: Collections that support case management require a relatively small group
of core journals. Students and health care professionals will need to search across
disciplines to identify appropriate literature.

Full Text: 2006\J Med Lib Ass94, E107.pdf
Abstract: Purpose: Emergency nursing covers a broad spectrum of health care from
319
trauma surgery support to preventive health care. The purpose of this study is to
identify the core literature of emergency nursing and to determine which databases
provide the most thorough indexing access to the literature cited in emergency
nursing journals. This study is part of the Medical Library Association’s Nursing and
Allied Health Resources Section’s project to map the nursing literature.
Methods: Four key emergency nursing journals were selected and subjected to citation
analysis based on Bradford’s Law of Scattering.
Results: A group of 12 journals made up 33.3% of the 7,119 citations, another 33.3% of
the citations appeared in 92 journals, with the remaining 33.3% scattered across 822
journals. Three of the core 12 journals were emergency medicine titles, and 2 were
emergency nursing titles from the selected source journals. Government publications
constituted 7.5% of the literature cited.
Conclusions: PubMed/MEDLINE provided the best overall indexing coverage for the
journals, followed by CINAHL. However, CINAHL provided the most complete
coverage for the source journals and the majority of the nursing and emergency
medical technology publications and should be consulted by librarians and nurses
seeking emergency nursing literature.

Abstract: Objectives: This study was designed to identify core journals for the nurse
practitioner specialty and to determine the extent of their indexing in bibliographic
databases.
Methods: As part of a larger project for mapping the literature of nursing, this study
followed a common methodology based on citation analysis. Four journals
designated by nurse practitioners as sources for their practice information were
selected. All cited references were analyzed to determine format types and
publication years. Bradford’s Law of Scattering was applied to identify core journals.
Nine bibliographic databases were searched to estimate the index coverage of the
core titles.
Results: The findings indicate that nurse practitioners rely primarily on journals (72.0%)
followed by books (20.4%) for their professional knowledge. The majority of the
identified core journals belong to non-nursing disciplines. This is reflected in the
indexing coverage results: PubMed/MEDLINE more comprehensively indexes the
core titles than CINAHL does.
Conclusion: Nurse practitioners, as primary care providers, consult medical as well as
nursing sources for their information. The implications of the citation analysis
findings are significant for collection development librarians and indexing services.

Abstract: Objectives: As part of a project to map the literature of nursing, sponsored by
the Nursing and Allied Health Resources Section of the Medical Library Association,
this study identifies core journals cited in nursing education journals and the
indexing services that cover the cited journals.
Methods: Three nursing education source journals were subjected to a citation analysis
of articles from 1997 to 1999, followed by an analysis of database access to the most
frequently cited journal titles.
Results: Cited formats included journals (62.4%), books (31.3%), government
documents (1.4%), Internet (0.3%), and miscellaneous (4.6%). Cited references were
relatively older than other studies, with just 58.6% published in the 1990s. One-third
of the citations were found in a core of just 6 journal titles; one-third were dispersed
among a middle zone of 53 titles; the remaining third were scattered in a larger zone
of 762 titles. Indexing coverage for the core titles was most comprehensive in
CINAHL, followed by PubMed/MEDLINE and Social Sciences Citation Index.
Conclusions: Citation patterns in nursing education show more reliance on nursing and
education literature than biomedicine. Literature searches need to include CINAHL
and PubMed/MEDLINE, as well as education and social sciences databases.
Likewise, library collections need to include education and social sciences resources
to complement works developed for nurse educators.

Medical Library Association, 94 (2 Suppl), E128-E136.
Full Text: 2006\J Med Lib Ass94, E128.pdf
Abstract: BACKGROUND: Pediatric nurses work in an interdisciplinary field and face
ever-increasing demands on their time and knowledge. Selection tools for librarians
serving this group are available, but only one bibliometric analysis has examined
citations to aid collection development. METHOD: The “Mapping the Literature of
Nursing Project” protocol was used. Three source journals were selected, and a
citation analysis of articles from 1998 to 2000 was conducted. RESULTS: The
frequency of journal citation was tabulated, and a list of the most frequently cited
journals was created. Just over 1% of the cited journals produced 33% of the
citations. PubMed/MEDLINE, Science Citation Index, and Social Sciences Citation
Index provided the most complete indexing coverage of all types of the journals,
while CINAHL providing the most complete coverage of nursing journals. Books
were the second-most frequently cited format. CONCLUSIONS: Citation analysis of
journal articles from pediatric nursing journals may be helpful in selecting journals
for libraries serving pediatric nurses and those who conduct pediatric nursing
research. Librarians should consider adding indexes to their collection in addition to
321
PubMed/MEDLINE to access the broad range of journals useful to this specialty.

Abstract: Objective: This paper describes a citation analysis of the literature of
rehabilitation nursing, conducted as part of the Medical Library Association’s
Nursing and Allied Health Section’s the “Mapping the Literature of Nursing
Project.”
Methods: One core journal, Rehabilitation Nursing, was selected, being both the official
journal of the Association of Rehabilitation Nurses and the only journal devoted
exclusively to rehabilitation nursing. Citations were analyzed according to format
and date and stratified according to Bradford’s Law of Scattering.
Results: The nineteen journals that constitute Zone 1 contribute the same number of
citations as the eighty-six journals that make up Zone 2. OCLC ArticleFirst,
PubMed/MEDLINE, and CINAHL provide the most inclusive coverage of the
rehabilitation literature. The source journal, Rehabilitation Nursing, is the most
important journal in Zone 1 and thus the most influential rehabilitation nursing
journal. Relative degrees of database coverage do not change between Zones 1 and 2.
Conclusion: The journals in Zones 1 and 2 collectively represent most of the important
subspecialties of rehabilitation nursing, such as the physiological, sociopsychological,
and community reintegration issues involved in the long-term rehabilitation process.

Full Text: 2006\J Med Lib Ass94, E143.pdf
Abstract: OVERVIEW: No bibliometric studies of the literature of the field of
transcultural nursing have been published. This paper describes a citation analysis as
part of the project undertaken by the Nursing and Allied Health Resources Section of
the Medical Library Association to map the literature of nursing. OBJECTIVE: The
purpose of this study was to identify the core literature and determine which
databases provided the most complete access to the transcultural nursing literature.
METHODS: Cited references from essential source journals were analyzed for a
three-year period. Eight major databases were compared for indexing coverage of the
identified core list of journals. RESULTS: This study identifies 138 core journals.
Transcultural nursing relies on journal literature from associated health sciences
322
fields in addition to nursing. Books provide an important format. Nearly all cited
references were from the previous 18 years. In comparing indexing coverage among
8 major databases, 3 databases rose to the top. CONCLUSIONS: No single database
can claim comprehensive indexing coverage for this broad field. It is essential to
search multiple databases. Based on this study, PubMed/MEDLINE, Social Sciences
Citation Index, and CINAHL provide the best coverage. Collections supporting
transcultural nursing require robust access to literature beyond nursing publications.

Full Text: 2006\J Med Lib Ass94, 415.pdf
Abstract: Objective: The paper identifies the relative amount of research devoted to
non-communicable disease in low- and middle-income countries (LMICs). Design:
A bibliometric analysis of a subset of journals published in LMICs was performed.
Measurements: Seventy-six peer-reviewed journals focused on general medicine or
public health published in 46 LMICs and indexed from 1998 to 2003 in MEDLINE.
A total of 24 journals were selected, 4 journals from each of 6 LMIC regions.
Searches were refined using 18 non-communicable disease topics with 7,012 articles
identified for analysis. Results: More than 40% of articles in LMIC regions focused
on non-communicable disease research. The percentage was highest in Eastern
Europe/Central Asia (47%) and lowest in Latin America (36%). The percentage of
articles published in Sub-Saharan Africa (38%) did not differ significantly from that
of Latin America or South Asia. Cardiovascular disease and cancer led the list of the
top ten most-indexed published topics by region. Conclusions: Even in regions
rampant with infectious diseases, some capability exists to conduct research on
non-communicable diseases. Greater attention should be paid to the conduct and
support of such research in LMICs, which will benefit these countries and may yield
clues to lower-cost solutions to the burden of these diseases worldwide.

Abstract: Context: Systematic reviews of qualitative research studies extend
323
understanding of health care beyond effectiveness to acceptability and user views.
Objective: The paper surveys reports of qualitative systematic reviews and, by
characterizing techniques used to identify articles for inclusion, proposes standards
for reporting of literature searches. Data Sources and Study Selection: A search of
MEDLINE was performed for qualitative systematic reviews published from 1988 to
December 2004, supported by searches of CINAHL, Web of Knowledge (including
the Science and Social Sciences Citation Index), and the Cochrane Methodology
Register, and Internet searches using the Copernic Agent Professional meta-search
agent. Studies were included if they used techniques of qualitative synthesis in
reviewing research studies in health care. Narrative reviews were excluded. Data
Extraction: Authors, year of publication, sampling strategy, databases, keywords, and
other approaches used were extracted. Data Synthesis: Sixty-four studies were
identified, and forty-three met inclusion criteria for this review. A summary of
searching methods was produced and used to construct the STARLITE mnemonic
(sampling strategy, type of study, approaches, range of years, limits, inclusion and
exclusions, terms used, electronic sources). Conclusions: Considerable variation
exists in search methods for qualitative systematic reviews. While diversity in
methods is appropriate during the development of review methodology, major
concerns remain about the absence of an accepted standard and the consequent poor
quality of reporting.

Full Text: 2006\J Med Lib Ass94, 430.pdf
Abstract: Objective: Bibliometric techniques were used to analyze the citation patterns
of researchers publishing in the American Journal of Veterinary Research (AJVR).
Methods: The more than 25,000 bibliographic references appearing in the AJVR
from 2001 to 2003 were examined for material type, date of publication, and
frequency of journals cited. Journal titles were ranked in decreasing order of
productivity to create a core list of journals most frequently used by veterinary
medical researchers. Results: The majority of items cited were journals (88.8%),
followed by books (9.8%) and gray literature (2.1%). Current sources of information
were favored; 65% of the journals and 77% of the books were published in 1990 or
later. Dividing the cited articles into 3 even zones revealed that 24 journals produced
324
7,361 cited articles in the first zone. One hundred thirty-nine journals were
responsible for 7,414 cited articles in zone 2, and 1,409 journals produced 7,422
cited articles in zone 3. Conclusions: A core collection of veterinary medicine
journals would include 49 veterinary medicine journals from zones 1 and 2. Libraries
supporting a veterinary curriculum or veterinary research should also include
veterinary medical journals from Zone 3, as well as provide access to journals in
non-veterinary subjects such as biochemistry, virology, orthopedics, and surgery and
a selection of general science and medical journals.

Abstract: Introduction: Given the common use of acronyms and initialisms in the health
sciences, searchers may be entering these abbreviated terms rather than full phrases
when searching online systems. The purpose of this study is to evaluate how various
MEDLINE Medical Subject Headings (MeSH) interfaces map acronyms and
initialisms to the MeSH vocabulary. Methods: The interfaces used in this study were:
the PubMed MeSH database, the PubMed Automatic Term Mapping feature, the
NLM Gateway Term Finder, and Ovid MEDLINE. Acronyms and initialisms were
randomly selected from 2 print sources. The test data set included 415 randomly
selected acronyms and initialisms whose related meanings were found to be MeSH
terms. Each acronym and initialism was entered into each MEDLINE MeSH
interface to determine if it mapped to the corresponding MeSH term. Separately, 46
commonly used acronyms and initialisms were tested. Results: While performance
differed widely, the success rates were low across all interfaces for the randomly
selected terms. The common acronyms and initialisms tested at higher success rates
across the interfaces but the differences between the interfaces remained. Conclusion:
Online interfaces do not always map medical acronyms and initialisms to their
corresponding MeSH phrases. This may lead to inaccurate results and missed
information if acronyms and initialisms are used in search strategies.

Abstract: OBJECTIVES: The research provides an overview of the health care
management literature and the indexing coverage of core journal literature.
METHOD: Citations from five source journals for the years 2002 through 2004 were
studied using the protocols of the Mapping the Literature of Allied Health Project
and Mapping the Literature of Nursing Project. The productivity of cited journals
was analyzed by applying Bradford’s Law of Scattering. RESULTS: Journals were
the most frequently cited format, followed by books. Only 3.2% of the cited journal
titles from all 5 source journals generated two-thirds of the cited titles. When only
the health care management practitioner-oriented source journals were considered,
two-thirds of the output of cited journal titles came from 10.8% of the titles. Science
Citation Index and PubMed provided the best overall coverage of the titles cited by
all 5 source journals, while the cited titles from the 2 practitioner-oriented journals
were covered most completely by Social Sciences Citation Index and Business
Source Complete. CONCLUSIONS: Health care management is a multidisciplinary
field. Librarians must consider the needs of their users and assist them by providing
the necessary materials and combination of indexes to access this field adequately.

Abstract: Purpose: This paper identifies the core literature of athletic training and
determines which major databases provide the most thorough intellectual access to
this literature. Methods: This study collected all cited references from 2002 to 2004
of three journals widely read by those in the athletic training field. Bradford’s Law of
Scattering was applied to the resulting list to determine the core journal titles in the
discipline. Three major databases were reviewed for extent of their coverage of these
core journals. Results: Of the total 8,678 citations, one-third referenced a compact
group of 6 journals; another third of the citations referenced an additional 40 titles.
The remaining 2,837 citations were scattered across 1,034 additional journal titles.
Conclusions: The number and scatter of citations over a three-year period identified
forty-six key journals in athletic training. The study results can inform athletic
trainers of the core literature in their field, encourage database producers (e.g.,
MEDLINE, SPORTDiscus, CINAHL) to increase coverage of titles that are not
indexed or underindexed, and guide purchasing decisions for libraries serving
athletic training programs.

Abstract: Objectives: The research sought to determine the publication types cited most
often in public health as well as the most heavily cited journal titles. Methods: From
a pool of 33,449 citations in 934 articles published in the 2003-2005 issues of
American Journal of Public Health, 2 random samples were drawn: one (n = 1,034)
from the total set of citations and one (n = 1,016) from the citations to journal articles.
For each sampled citation, investigators noted publication type, publication date,
uniform resource locator (URL) citation (yes/no), and, for the journal article sample,
journal titles. The cited journal titles were analyzed using Bradford zones. Results:
The majority of cited items from the overall sample of 1,034 items were journal
articles (64.4%, n = 666), followed by government documents (n 130), books (n =
122), and miscellaneous sources (n = 116). Publication date ranged from 1826-2005
(mean = 1995, mode = 2002). Most cited items were between 0 and 5 years old
(50.3%, n = 512). In the sample of 1,016 journal article citations, a total of 387
journal titles were cited. Discussion: Analysis of cited material types revealed results
similar to citation analyses in specific public health disciplines, including use of
materials from a wide range of disciplines, reliance on miscellaneous and
government documents, and need for older publications.

Abstract: Objective: The objective of this study was to analyze bibliometric data from
ISI, National Institutes of Health (NIH)-funding data, and faculty size information
for Association of American Medical Colleges (AAMC) member schools during
1997 to 2007 to assess research productivity and impact. Methods: This study
327
gathered and synthesized 10 metrics for almost all AAMC medical schools (n=123):
(1) total number of published articles per medical school, (2) total number of
citations to published articles per medical school, (3) average number of citations per
article, (4) institutional impact indices, (5) institutional percentages of articles with
zero citations, (6) annual average number of faculty per medical school, (7) total
amount of NIH funding per medical school, (8) average amount of NIH grant money
awarded per faculty member, (9) average number of articles per faculty member, and
(10) average number of citations per faculty member. Using principal components
analysis, the author calculated the relationships between measures, if they existed.
Results: Principal components analysis revealed 3 major clusters of variables that
accounted for 91% of the total variance: (1) institutional research productivity, (2)
research influence or impact, and (3) individual faculty research productivity.
Depending on the variables in each cluster, medical school research may be
appropriately evaluated in a more nuanced way. Significant correlations exist
between extracted factors, indicating an interrelatedness of all variables. Total NIH
funding may relate more strongly to the quality of the research than the quantity of
the research. The elimination of medical schools with outliers in 1 or more indicators
(n=20) altered the analysis considerably. Conclusions: Though popular, ordinal
rankings cannot adequately describe the multidimensional nature of a medical
school’s research productivity and impact. This study provides statistics that can be
used in conjunction with other sound methodologies to provide a more authentic
view of a medical school’s research. The large variance of the collected data suggests
that refining bibliometric data by discipline, peer groups, or journal information may
provide a more precise assessment.

Abstract: Objectives: The aim of this study was to locate the scientific literature dealing
with addiction to the Internet, video games, and cell phones and to characterize the
pattern of publications in these areas. Methods: One hundred seventy-nine valid
articles were retrieved from PubMed and PsycINFO between 1996 and 2005 related
to pathological Internet, cell phone, or video game use. Results: The years with the
highest numbers of articles published were 2004 (n=42) and 2005 (n=40). The most
productive countries, in terms of number of articles published, were the United States
(n=52), China (n=23), the United Kingdom (n=17), Taiwan (n=13), and South Korea
(n=9). The most commonly used language was English (65.4%), followed by
Chinese (12.8%) and Spanish (4.5%). Articles were published in 96 different
journals, of which 22 published 2 or more articles. The journal that published the
most articles was Cyberpsychology & Behavior (n=41). Addiction to the Internet
was the most intensely studied (85.3%), followed by addiction to video games
(13.6%) and cell phones (2.1%). Conclusions: The number of publications in this
area is growing, but it is difficult to conduct precise searches due to a lack of clear
terminology. To facilitate retrieval, bibliographic databases should include descriptor
terms referring specifically to Internet, video games, and cell phone addiction as well
as to more general addictions involving communications and information
technologies and other behavioral addictions.

Abstract: Objective: This study analyzed trends in research activity as represented in the
published research in the leading peer-reviewed professional journal for health
sciences librarianship. Methodology: Research articles were identified from the
Bulletin of the Medical Library Association and Journal of theMedical Library
Association (1991-2007). Using content analysis and bibliometric techniques, data
were collected for each article on the (1) subject, (2) research method, (3) analytical
technique used, (4) number of authors, (5) number of citations, (6) first author

affiliation, and (7) funding source. The results were compared to a previous study,
covering the period 1966 to 1990, to identify changes over time. Results: Of the 930
articles examined, 474 (51%) were identified as research articles. Survey (n=174,
37.1%) was the most common methodology employed, quantitative descriptive
statistics (n=298, 63.5%) the most used analytical technique, and applied topics
(n=332, 70%) the most common type of subject studied. The majority of first authors
were associated with an academic health sciences library (n=264, 55.7%). Only
27.4% (n=130) of studies identified a funding source. Conclusion: This study’s
findings demonstrate that progress is being made in health sciences librarianship
research. There is, however, room for improvement in terms of research
methodologies used, proportion of applied versus theoretical research, and
elimination of barriers to conducting research for practicing librarians.

Abstract: Objective: This research measures the effectiveness of the practice of
correction and republication of invalidated articles in the biomedical literature by
analyzing the rate of citation of the flawed and corrected versions of scholarly
articles over time. If the practice of correction and republication is effective, then the
incidence of citation of flawed versions should diminish over time and increased
incidence of citation of the republication should be observed. Methods: This is a
bibliometric study using citation analysis and statistical analysis of pairs of flawed
and corrected articles in MEDLINE and Web of Science. Results: The difference
between citation levels of flawed originals and corrected republications does not
approach statistical significance until eight to twelve years post-republication.
Results showed substantial variability among bibliographic sources in their provision
of authoritative bibliographic information. Conclusions: Correction and republication
is a marginally effective biblioremediative practice. The data suggest that
inappropriate citation behavior may be partly attributable to author ignorance.

Abstract: Objective: This paper presents the methods and results of a study designed to
produce the third edition of the “Basic List of Veterinary Medical Serials,’’ which
was established by the Veterinary Medical Libraries Section in 1976 and last updated
in 1986. Methods: A set of 238 titles were evaluated using a decision matrix in order
to systematically assign points for both objective and subjective criteria and
determine an overall score for each journal. Criteria included: coverage in four major
indexes, scholarly impact rank as tracked in two sources, identification as a
recommended journal in preparing for specialty board examinations, and a veterinary
librarian survey rating. Results: Of the 238 titles considered, a minimum scoring
threshold determined the 123 (52%) journals that constituted the final list. The 36
subject categories represented on the list include general and specialty disciplines in
veterinary medicine. A ranked list of journals and a list by subject category were
produced. Conclusion: Serials appearing on the third edition of the “Basic List of
Veterinary Medical Serials’’ met expanded objective measures of quality and impact
as well as subjective perceptions of value by both librarians and veterinary
practitioners.

using Bradford’s Law of Scattering. Results: There were 19,907 citations in 602
source articles. Journal articles were the most commonly cited format type. Of the
1,896 journal titles cited, 20 (1.1%) made up the core journals. Together, the fields of
medicine, health education, and psychology accounted for 85.0% of the journals in
331
the core. Self-citation was found to be a common practice in the source journals.
Scopus had the broadest journal coverage of the indexes examined. Conclusions: The
results of this study provide a new picture of the health education literature: The
volume has grown significantly, cites older materials, and relies less on sexual health
journals and more on psychology journals.

Ribotype differences between clinical and environmental isolates of Burkholderia
pseudomallei. Journal of Medical Microbiology, 46 (7), 565-570.
Abstract: Burkholderia pseudomallei is isolated frequently from the soil in regions
where the disease melioidosis occurs. However, recent surveys in Thailand have
shown that the frequency of isolation of the organism from soil samples is not
directly related to the incidence of melioidosis in an area. To determine whether
strain populations of B. pseudomallei prevalent in soil are gentypically related to
strains causing clinical disease, rRNA BamHI restriction fragment length
polymorphisms (RFLP) of 139 soil environmental isolates and 228 human isolates
were compared. Two groups of ribotype patterns were found. Group I comprised 37
different ribotype patterns which were characterised by five to eight hybridisation
bands of 2.8-> 23 kb. All of these ribotypes were identified among the clinical
isolates, and 18 of them were also found in 59 environmental isolates. Group II was
represented by 12 ribotypes found only in environmental strains. These ribotype
patterns comprised one to five bands in the size range 9-> 23 kb. All but one of the
73 isolates in this group grew on a minimal medium supplemented with L-arabinose.
In contrast, only 3% of the 66 isolates from the environment with group I ribotype
patterns could utilise this sugar as their sole energy source. These findings suggest
that B. pseudomallei strains that utilise arabinose constitute a population that is
genetically distinct from other environmental and clinical strains.

Abstract: With regard to the relatively limited water supply in the area of Dalmatia
(Southern Croatia), water supply system and health care institutions are especially
interested in observing and monitoring the waters, as well as preserving their quality.
The ecological need to sum up the work on water quality investigations led us to
monitor the environment. Because it is necessary, from the informatical aspect, to
organize mass ecological health data into databases, the relational database for the
research of chemical analyses (coefficients K1 and K2) as the methodological
foundation for the study of the ecological factors that influence human health is
defined in this paper. Results used for the prototype implementation subsystem of the
chemical water analysis control are based on the investigations of the Water

Abstract: The objective is to determine the extent to which information systems (IS) for
cancer are unique and necessary. Via an analysis of Medical Subject Headings used
to index relevant literature and other bibliometric techniques, cancer IS are compared
and contrasted with IS of other specialties. Cancer IS are relatively little discussed
334
and primarily connect radiation equipment with the radiation oncology staff. By
contrast, clinical laboratory and radiology IS are frequently discussed and connect
specialized equipment to the hospital. A “Specialty Need” model accounts for these
patterns and says that the “need for a specialty IS” is proportional to the “uniqueness
of the specialty tools” plus the “degree to which the information from those tools is
needed throughout the particular health care entity.”.

Abstract: The quantity and quality of published research in the field of Virology by
different world regions was estimated in this study. Using the PubMed database,
articles from journals included in the “Virology” category of the “Journal Citation
Reports” database of the Institute for Scientific Information for the period 1995-2003
were retrieved. The world was divided into nine regions based on geographic,
economic, and scientific criteria. Data on the country of origin of the research was
available for 33,425 out of 33,712 articles (99.2% of all articles from the included
journals). USA exceeds all other world regions in research production for the period
studied (42% of total articles), with Western Europe ranking second (35.7%). The
mean impact factor in articles published in Virology journals was highest for the
USA (4.60), while it was 3.90 for Western Europe and 3.22 for the rest of the world
(seven regions combined). USA and Canada ranked first in research productivity
when both gross national income per capita (GNIPC) and population were taken into
account. The results of this analysis show a distressing fact; the absolute and relative
production of research in the field of Virology by the developing regions is very low,
although viral diseases cause considerable morbidity and mortality in these areas. It
is evident from this study that developing regions need more help from the developed
regions to enhance research infrastructure. (c) 2005 Wiley-Liss, Inc.

Full Text: J\J Mem Sci36, 363.pdf
Abstract: Many industrial processes such as printing, metal cleaning or painting produce
waste air streams containing low concentrations of organic solvents, such as acetone,
toluene, perchloroethane, xylene, etc. The total value of the solvent lost with the
waste air is considerable. In addition, these solvents represent a significant pollution
problem, and in recent years several procedures for recovering solvents from air,
such as carbon adsorption, incineration, etc. have been introduced in the industry. All
of them show some draw-backs in terms of efficiency, reliability and costs. In this
paper a membrane process is described, which provides an attractive alternative to
the conventional methods. In a basic study the permeabilities of acetone, toluene,
xylene, dichloroethane and dichloromethane through a homogeneous
polydimethylsiloxane (PDMS) membrane have been determined using a pressure
difference between 400 and 1000 mbar as driving force. The selectivity of the
membrane for the various solvents and their dependence on the solvent concentration
in a mixture with nitrogen were studied. The selectivities of the PDMS membrane for
the solvent/nitrogen mixtures were in the range of S = 70-160, depending on the
338
solvent and its concentration in the feed mixture. Based on these data a pilot plant
process has been designed in which a solvent is recovered from a waste air stream
and the depleted air is recycled into the waste air producing process. The solvent
which has permeated the membrane is recovered as a liquid by condensation. Thus,
complete recycling of air and solvents is possible. In a cost analysis it has been
demonstrated that the membrane process is indeed an attractive alternative to
conventional air cleaning techniques.

Abstract: The nitrate selectivities of commercially available anion exchange membranes
were investigated in batch electrodialysis experiments with synthetic drinking water
at relatively low current densities. High selectivities were found for sea water
concentration membranes and those are thus preferred for nitrate removal from
drinking water using electrodialysis. The best performance was found for the
Neosepta ACS anion exchange membrane of Tokuyama Soda Co. The monovalent
cation selectivities in drinking water are much the same for all standard grade cation
exchange membranes. The special grade water softening membranes can be used in
combination with sea water concentration AX membranes to remove nitrate from
hard waters.

Full Text: J\J Mem Sci87, 219.pdf
Abstract: The application of crossflow microfiltration for the treatment of industrial
wastewaters containing toxic heavy metals is described and the performance
quantified and compared with technologies which are traditionally used for the
treatment of such wastewaters. Case histories of the treatment of wastewaters
generated from the metal plating industry and a battery recycling plant are given
together with the operational performance of the full scale crossflow microfiltration
plants which were subsequently installed. Metals of particular interest are cadmium,
mercury and chromium where removals down to the ppb range are currently being
requested. Heavy metal bearing effluents have traditionally been treated by the
adjustment of the pH with lime or caustic soda to precipitate hydrated metal oxides.
Sometimes a sulphide compound or other materials are added which cause the
production of heavy metal compounds with lower solubility products. Removal of
339
the heavy metal precipitate is then usually accomplished by settlement, occasionally
followed by sand filtration [1]. With the advent of more stringent environmental
legislation regarding the quality of the final disposal stream, the use of crossflow
microfiltration is becoming an attractive alternative to the more conventional
methods of treatment. The performance of settling tanks, settling tanks in
conjunction with sand filters and a crossflow microfiltration system was assessed by
pilot trials on a mixed plating effluent. The tests were carried out by Cory
Environmental at their West Thurrock treatment plant in London. This plant is a
toxic waste plant which receives and treats industrial wastewaters from UK
industries. Tests were also carried out at a lead-acid battery breaking, lead recovery
and refining plant, the waste water from this plant required treatment before disposal
into the River Thames. The crossflow microfiltration system is based upon the
concept of using a dynamic membrane to form the filtration medium. This membrane
is laid down on the internal wall of a woven fabric cloth and may be formed by either
the solids naturally present in the feed suspension or by the deposition of materials
such as diatomaceous earth, metal hydroxides or kaolin. In this application the heavy
metal precipitate provides a suitable membrane without the introduction of filter aids.

Abstract: Microporous polyvinylbutyral membranes were prepared by a solvent-casting
technique. An affinity dye, i.e., Cibacron Blue F3GA was then immobilized. These
affinity membranes with a high water content of 89%, and carrying 3.3 mmol
Cibacron Blue F3GA/m2 membrane were used in the adsorption/stripping of some
selected heavy-metal ions (e.g. Cu(II), Zn(II), Cd(II) and Pb(II)) from aqueous media
containing different amounts of these ions (0.024-4.60 mmol/l) and at different pH
values (2.0-9.0). Adsorption rates were very high, and adsorption equilibria were
reached in ca. 15 min. The maximum adsorptions of heavy-metal ions onto the
Cibacron Blue F3GA-immobilized affinity membranes from their single solutions
were 7.0 mmol/m2 for Cu(II), 16.8 mmol/m2 for Zn(II), 22.2 mmol/m2 for Cd(II), and
34.2 mmol/m2 for Pb(II). Similar behavior wasobserved when the heavy-metal ions
competed (in the case of theadsorption from their mixture), the order of affinity was
Pb(II) > Cd(II) > Zn(II) > Cu(II). Heavy-metal ions regeneration was achieved by
using 0.1 M HNO3 in 30 min. It was observed that heavy-metal ions could be
repeatedly adsorbed and stripped without significant loss in adsorption capacity.

Abstract: During tangential filtration of solid-liquid suspensions, cake formation occurs
at membrane surface, a major consequence of which is a decline of flux to, at best, a
limit value. In order to show the influence of the composition and properties of the
fluid on cake formation, experiments have been performed with a colloidal
suspension of clay in the absence or in the presence of protein. We have studied the
effects of solution characteristics (ionic strength and pH) on physico-chemical
properties of the suspension, such as mean diameter and zeta potential and on
separation performances such as ultrafiltration Limiting flux. By taking into account
341
electrostatic interactions, it has been possible to explain (i) the evolution in the
adsorption isotherms of the protein on the clay with the physico-chemical conditions
(II) the consequences of this adsorption on the limiting flux. (C) 1997 Elsevier

Abstract: The reduction of nitrate to nitrogen in aqueous solutions by means of
catalytically active membranes has been investigated. A heterogeneous catalyst (Pd,
Cu) has been incorporated in a microporous polyetherimide membrane. After
saturation with hydrogen nitrate containing water was filtered through these
membranes. The nitrate reduction was studied as a function of pH, volume flow and
342
temperature. It could be demonstrated that the catalyst remained active in the
polymer matrix. The calculated activation energy for nitrate reduction is indicating
that the reaction is dominated by mass transfer and diffusion. (C) 1998 Elsevier

Abstract: The effects of solution chemistry on the rate and extent of adsorption of a
protein (BSA) and humic acid (Suwannee River humic acid) onto a regenerated
cellulose ultrafiltration membrane were studied. Isotherms were performed to
determine equilibrium adsorption behavior. Rate of adsorption was determined by
measuring adsorbed mass as a function of time. Experiments were performed at
differing conditions of pH, ionic strength and bulk feed concentration. For both
compounds, adsorption was higher at lower pH values. Adsorption decreased as pH
increased. Increased salt concentration reduces electrostatic repulsion between
like-charged material (increasing adsorption) and decreases electrostatic attraction
between oppositely charged material (decreasing adsorption), These interactions
between the adsorbing material and the membrane surface affect the adsorption rate,
which was evaluated using two mechanistic models, The modeling was designed to
determine the governing mechanism in adsorption onto the hydrophilic membrane
surface. These models confirmed that, under conditions of this study, the transport
rate to the membrane surface is fast compared to the reactions at the membrane
surface, thus electrostatic interactions are very important in determining adsorption
of this material onto the membrane. Controlling electrostatic interactions could
reduce adsorption of protein and humic material onto the membrane, consequently
reducing long-term membrane fouling. Parameters from the models developed in this
study can be used to determine the “fouling potential” of a given feed stream,

Abstract: The removal of divalent metal ions including Cu(II), Co(II), Ni(II), and Zn(II)
from aqueous solutions by membrane filtration was studied with the help of
water-soluble chitosan. The Amicon regenerated cellulose YM10 and YM30 were
used as ultrafilters. Experiments were performed as a function of aqueous pH, the
concentration ratio of chitosan to metals (beta), and applied pressure (P). It was
shown that at neutral condition the removal of Cu(II) was more efficient compared to
other metals. Furthermore, metal removal from acidic solutions (pH < 6) could be
enhanced by 6-10 times via the addition of chitosan. The effect of the presence of
inorganic salts on the removal was also studied. Finally, the fouling phenomena
during filtration was analyzed by conventional filtration theory considering
compressible nature of the deposited gel.

Abstract: A review of affinity membrane publications from 1989 to 1999 is presented
containing six major divisions: (a) modification of existing membranes for affinity
adsorption applications; (b) membranes specifically prepared for affinity binding; (c)
module designs for immuno- and other affinity sorption processes; (d) the kinetics of
the affinity sorption process; (e) a selection of interesting applications that have
appeared during the period and (f) a summary of reviews published during the period.
Although there have been a large number of membrane preparation and process
applications described in the literature during the period covered by the review, the
commercialization of affinity membranes remains meager: One purpose f the review
is to point out opportunities for more applied development of affinity membranes,
including the design of appropriate modules to house them. From the available
literature it should be possible to produce high efficiency separation devices based on
the combination of sieving and adsorption characteristics of affinity membranes. (C)

Abstract: A general overview on the potentiality of membrane processes in the
treatment of aqueous solutions coming from the leather industry is reported. The wet
operations of the leather cycle which can be combined with or modified by
membrane processes, such as microfiltration, ultrafiltration (UF), nanofiltration (NF)
and reverse osmosis, have been described on the basis of consolidated applications
and experimental tests on laboratory and industrial pilot scale. Some new
applications are also proposed.
The membranes and modules employed for the treatment of the effluents, pretreatment
of fluids, cleaning procedures and fluid dynamic conditions in experimental
applications are reported and discussed. An outline of direct and indirect energy
analysis of tanning operations and the results of a mathematical model applied to the
degreasing step are also presented.
The integrated membrane processes described permit to rationalize the tanning cycle
realizing the recovery and the recycle of several chemicals utilized in the tanneries.
A reduction of environmental impact, a simplification of cleaning-up processes of
wastewaters, an easy re-use of sludges, a decrease of disposal costs, a saving of
chemicals and water and of direct and indirect energy are some advantages coming
from the described membrane operations. In the future a wider application of the
more consolidated membrane processes in this field is expected in the plant
innovation phase of a tanning factory. (C) 2001 Elsevier Science B.V. All rights

Abstract: In this contribution an overview is given about the state-of-the-art at the
membrane development for proton-conductive polymer (composite) membranes for
the application membrane fuel cells, focusing on the membrane developments in this
field performed at ICVT. For preparation of the polymers, processes have been
developed for sulfonated arylene main-chain polymers as well as for arylene
main-chain polymers containing basic N-containing groups, including a lithiation
step. Covalently cross-linked polymer membranes have been prepared by alkylation
of the sulfinate groups of sulfinate group-containing polymers with alpha, omega
-dihalogenoalkanes. The advantage of the covalently cross-linked ionomer
membranes was their dimensional stability even at temperatures of 80-90°C, their
345
main disadvantage their brittleness when drying out, caused by the inflexible
covalent network. Sulfonated and basic N-containing polymers (commercial
polymers as well as self-developed ones) have been combined to acid-base blends
containing ionic cross-links. The main advantage of these membrane type was its
flexibility even when dried-out, its good to excellent thermal stability, and the
numerous possibilities to combine acidic and basic polymers to blend membranes
having fine-tuned properties. The main disadvantage of this membrane type was the
insufficient dimension stability at T > 70-90°C, caused by breakage of the ionic
cross-links, where the ionic cross-links broke as easier as lower the basicity of the
polymeric base was. Some of the acid-base blend membranes were applied to H-2
membrane fuel cells and to direct methanol fuel cells up to 100°C, yielding the result
that these membranes show very good perspectives in the membrane fuel cell
application. (C) 2001 Elsevier Science B.V. All rights reserved.

Abstract: The transport properties and the swelling behaviour of NAFION and different
sulfonated polyetherketones are explained in terms of distinct differences on the
microstructures and in the pK(a) of the acidic functional groups. The less pronounced
hydrophobic/hydrophilic separation of sulfonated polyetherketones compared to
NAFION corresponds to narrower, less connected hydrophilic channels and to larger
separations between less acidic sulfonic acid functional groups. At high water
contents, this is shown to significantly reduce electroosmotic drag and water
permeation whilst maintaining high proton conductivity. Blending of sulfonated
polyetherketones with other polyaryls even further reduces the solvent permeation (a
factor of 20 compared to NAFION), increases the membrane flexibility in the dry
state and leads to an improved swelling behaviour. Therefore, polymers based on
sulfonated polyetherketones are not only interesting low-cost alternative membrane
material for hydrogen fuel cell applications, they may also help to reduce the
problems associated with high water drag and high methanol cross-over in direct
liquid methanol fuel cells (DMFC). The relatively high conductivities observed for
oligomers containing imidazole as functional groups may be exploited in fully
346
polymeric proton conducting systems with no volatile proton solvent operating at
temperatures significantly beyond 100C, where methanol vapour may be used as a
fuel in DMFCs. (C) 2001 Elsevier Science B.V. All rights reserved.

Abstract: Critical fluxes were determined by constant flux ultrafiltration (UF)
experiments under laminar flow conditions. The experiments were performed by
using hydrophilic C30G and hydrophobic GR51 ultrafiltration membranes and dilute
myoglobin solutions and baker’s yeast suspensions as model colloids. Solution
concentration, pH and cross-flow were investigated. The critical flux increased with
increasing flow velocity and decreasing solute concentration. The regenerated
cellulose C30G membrane exhibited hi-her critical fluxes than the polysulphone
GR51 membrane. The highest critical flux was obtained at pH 8 in the presence of
repulsive electrostatic forces between the molecules and the surface of the membrane
and the lowest at the isoelectric points of the colloids. In the case of baker’s yeast
below the critical flux, the flux was about the same as the pure buffer solution flux
showing a strong form of the critical flux. This also occurred with the C30G
membrane at low concentrations of myoglobin except at pH 6 when a weak form of
the critical flux was measured. With the GR51 membrane, the permeate flux deviated
from the pure buffer solution flux even at the lowest fluxes. (C) 2002 Elsevier

Abstract: The paper presents the characteristics of membrane-sorption integrated
process, which comprise sorption of the solute with membrane separation of the
sorbent. The main advantage of this separation method is the high efficiency and
lower costs of the process comparing with classical sorption in fixed beds. The
variety of sorbents and binding materials in form of very fine particles may be
applied in this system. This increases the specific surface of the sorbent and
consequently rise the uptake of the sorbate and enhances kinetics. Moreover, the high
347
intensity of the process may be achieved due to synergetic effects of sorbent
concentrating at membrane vicinity. The best results may be accomplished when flux
is maintained below critical value and when the permeate flux is fully synchronized
with the sorption kinetics and rate of sorbent renewal on membrane surface.
Sorbent’s “residence time” at membrane surface may be controlled by various means
such as backflushing, cross-flow, reverse flow, pulsations, gas sparking, etc. The
experimental results on membrane biosorption of heavy metals fully support this idea.
The mathematical model enables to attain the optimum process conditions. A new
factor, i.e. biosorption efficiency has been introduced as a criterion to evaluate the
process performance, which comprised yield and selectivity of separation
simultaneously.

Abstract: Poly(hydroxyethyl methacrylate), pHEMA, and a composite pHEMA/chitosan
networks were synthesized in the membrane form via UV initiated
photo-polymerisation in the presence of an initiator ,‘-azoisobutyronitrile.
Reactive Yellow 2 (RY-2) was covalently immobilised as a dye–ligand onto both
membranes. The polarity and surface energy of the investigated membranes were
determined by contact angle measurement. The incorporation of chitosan in the
pHEMA networks produced more hydrophilic surface, as indicated by contact angle
analysis. The binding characteristics of lysozyme, -globulins, human serum albumin
(HSA) and bovine serum albumin (BSA) to pHEMA-RY-2 and
pHEMA/chitosan-RY-2 affinity membranes have been investigated from aqueous
solution and their dye–ligand free forms were used as control systems. When
chitosan was incorporated in the pHEMA network as a cationic polymer led to higher
adsorption capacity for the lysozyme. Selective adsorption behaviour was also
observed in the case of pHEMA/chitosan-RY-2 membrane for the lysozyme. The
non-specific adsorptions of the lysozyme on the pHEMA and pHEMA/chitosan
membranes were about 1.9 and 7.2 mg/ml, respectively. These were negligible for all
others investigated proteins. The lysozyme adsorption data was analysed using the
first-order and the second-order models. The first-order equation in both affinity
membrane systems is the most appropriate equation to predict the adsorption
capacities of the adsorbents. The adsorption isotherms well fitted the combined
Langmuir–Freundlich model. A theoretical analysis has been conducted to estimate
348
the thermodynamic contributions (changes in enthalpy, entropy and Gibbs free
energy) for the adsorption of lysozyme to both dye–ligand immobilised membranes.
The adsorption capacities of both dye–ligand immobilised membranes increased with
increasing the temperature while decreased with increasing the NaCl concentration.
Both affinity membranes are stable when subjected to sanitization with sodium
hydroxide after repeated separation–elution cycles.

Abstract: A novel adsorption membrane was prepared by immobilizing condensed
vegetable tannins onto collagen fiber membrane. The tannins immobilized onto the
membrane keep their ability of chelating metal ions and can withstand the exposure
to water and organic agents. The adsorption capacities of bayberry tannin and black
wattle tannin immobilized membranes to UO22+ were 56.8 mg U/g and 53.0 mg U/g,
respectively, at 303 K when the initial concentration of UO22+ was 263 mg U/L.The
adsorption isotherm of tannins immobilized membrane to UO22+ can be described by
the Freundlich model. The adsorption kinetics of the membrane to UO22+ can be well
described by the pseudo-second-order rate model. The adsorption capacity calculated
by the pseudo-second-order rate model was closed to that determined by actually
measurement. The continuous adsorption–desorption studies indicated that this kind
of adsorption membrane has excellent adsorption–desorption properties. For
monolayer membrane, more than 90% UO22+ was adsorbed when 500 mL UO22+
solution (conc. 263 mg U/L) passed through it. When three layers of membrane were
employed, no UO22+ was detected until 1000 mL the effluent was collected. The
membrane can be easily regenerated by a small quantity of 0.1 M HNO3 after
adsorption, and therefore UO22+ can be greatly concentrated. The repeated
adsorption–desorption experiments confirmed that the tannins immobilized
membrane could be used for at least 10 times without considerable decrease of
adsorption capacity.

Abstract: Industrial textile processing comprises the operations of pretreatment, dyeing,
printing and finishing. These production processes are not only heavy consumers of
energy and water; they also produce a substantial amount of chemical pollution. Of
all dyed textile fibres, cotton occupies the number-one position, and more than 50%
of its production is dyed with reactive dyes, owing to their technical characteristics.
Unfortunately, this class of dyes is also the most unfavorable one from the ecological
point of view, as the effluents produced are relatively heavily colored, contain high
concentrations of salt and exhibit high BOD/COD values. Dyeing 1 kg of cotton with
reactive dyes requires an average of 70-150L water, 0.6 kg NaCl and 40 g reactive
dye. The composition of the dye bath which we propose to treat contains solid
particles (cotton fibres), dyeing auxiliaries (organic compounds), hydrolyzed reactive
dyes, substantial quantities of alkalis (sodium carbonate and soda ash) and very high
concentration of sodium chloride or sodium sulfate. This paper presented the state of
the art of the different processes currently used for the treatment of dye house
wastewaters and evaluated a four-step process [1] to recover the water and the
mineral salts, while leaving the spent dyes in the reject stream. Processes evaluated
included (1) cartridge filtration to remove textile fibres, (2) acidification to make the
brine recovered, suitable for reuse and further dyeing operations, (3) nanofiltration
(NF) to concentrate the hydrolyzed dyes and (4) reverse osmosis (RO) to further
concentrate the salts for reuse in the dyeing process. A cut-off of 100 mu m is
sufficient to trap textile fibres, regardless of the type of effluent and the texture of the
textile dyed. The hydrolyzed reactive dyes present in the treated effluents comprise
the entire range of possible types of reactive dyes. For this acidification, we studied
the influence of the concentration of sodium chloride, the influence of the
temperature and we verified that the volume neither depends on the concentrations of
reactive hydrolyzed dyes nor sodium chloride. After defining the nanofiltration
membrane, we studied the effect of the pH, temperature, pressure and velocity as
well as the experimental procedure on the permeate flux, recovery of the salt and
removal of the color. An increase of either of the parameters temperature and
pressure leads to an increase of the permeate flux. On the other hand, a rise in the pH
leads to a decrease of the permeate fiux. The retention factor of the sodium chloride
is low when the concentration of sodium chloride is high in the retentate. Our aim
was to recover 80-90% of the sodium chloride, but our experiments showed that the
recovery went as high as 99%. Depending on the dyes used, the experimental
procedure can be carried out in one, two or three steps. The dye retention level was
always higher than 98%. After studying the operating variables, experiments with the
350
recycled brines in new dyeing operations were carried out with specimen dyeings
prepared with usual water using different classes of reactive dyes. There was no
difference in the results in terms of depth, shade or fastness properties, whichever
type of water was used. These last results therefore validate our process and its
special innovative feature: recycling not only the water but also the mineral salts. (c)

Abstract: The adsorption of Pt(IV) and Pd(II) on bayberry tannin immobilized collagen
fiber (BTICF) membrane was investigated. The optimal pH for the adsorption of
Pt(IV) and Pd(II) ions was found to be 3.0 and 4.0, respectively. The time for
attaining adsorption equilibrium of Pt(IV) and Pd(II) was 60 and 240 min. The
adsorption kinetic data of the two metal ions are well fitted by the
pseudo-second-order model. The adsorption capacities of Pt(IV) and Pd(II) on 0.100
g BTICF membrane were 41.7 and 27.5 mg/g at 313 K. The adsorption isotherms of
the membrane to both the ions are described by the Langmiur model. The adsorption
extent remarkably increases with the increase of temperature and the ratio of
membrane material to solution volume. The membrane saturated by Pt(IV) is easily
regenerated by 0.1 M thiuorea, but the full regeneration is difficult after adsorption of
Pd(II). The continuous adsorption experiments of 58.3 mg/L Pt(IV) and 48.8 mg/L
Pd(II) solutions were undertaken by using three layers of membrane (total area 191
cm2), and it was found that no Pt(IV) and Pd(II) ions were detected until 700 and
1000 ml effluents were collected, respectively. Furthermore, competitive adsorption
studies revealed that the membrane exhibits ability of selective adsorption to Pt(IV)
and Pd(II) in the mixture solutions of metal ions.

Abstract: Macroporous chitosan membranes were prepared by using NaCl particles
porogen and genipin as cross-linking agent. For characterization and sorption
behavior comparison, other genipin cross-linked chitosan membranes were prepared
351
by either freeze drying or by using silica particles as porogen. The mean pore
diameter, the porosity, the crystallinity index (CrI) as well as the effect of the drying
procedures of these chitosan membranes were examined. NaCl reduced the CrI of the
chitosan membrane. The oven drying (01)) procedure decreased the mean pore
diameter, the porosity, and increased the CrI of the chitosan membranes when
compared with the vacuum drying (VD) procedure. The heat treatment of chitosan
membrane in aqueous NaOH to attract silica porogen increased the CrI of the
membrane. Under the same conditions, the membranes prepared with NaCl had
better sorption performance on RR 189 and Cu2+ than other membranes. The
maximum sorption capacity (q(e)) reached 1836.17 mg RR 189/g chitosan and
151.98 mg Cu2+/g chitosan. The pore diameter (d(pore)) of the membranes was much
larger than the diameter of the adsorbate molecules (d(adsorbate)), such that the ratio
of d(pore)/d(adsorbate) had little influence on q(e). The porosity and the amorphous
extent of the membranes were almost the same on q(e). When using tyrosinase
catalyzing, the hydrocaffeic acid (HCA) grafted on the NaCl treated chitosan
membrane was almost 10 times more than on chitosan beads. The chitosan
membrane prepared with NaCl can be used as a good adsorbent with high loading
capacity for implanting molecules (such as ligands, enzymes, etc.) on. (c) 2006

Abstract: The removal of methyl violet 28, a cationic dye, from water using two kinds
of strong-acid cation exchange membranes, ICE 450 supported (with sulfonic acid
groups and ion exchange capacity of 9.6-31 mu eq/47 mm disc) and P81 (with
phosphate groups and ion exchange capacity of 312 mu eq/47 mm disc), was
investigated in this study. In the batch process, the adsorption isotherm results show
that the P81 membrane exhibited a greater maximum adsorption capacity than the
ICE 450 supported membrane. However, the latter exhibited stronger and faster dye
adsorption behaviors. Different desorption solutions were tested in the batch
desorption process and, for both membranes, the best desorption performance
(similar to 100%) was achieved with an aqueous solution containing 1 M NaCl in
60% methanol. In the membrane chromatography process with one piece of 47 mm
membrane at a flow rate of 1 or 8 mL/min, complete dye removal and recovery from
a 20 mL feed with an initial dye concentration of 0.015 g/L could be achieved for
352
both membranes. The performance of both membranes remained practically
unaltered during three successive cycles of dye adsorption and desorption. Lastly, to
mimic the effluent produced by a typical dyehouse, a synthetic dye wastewater made
up of 0.03 g/L methyl violet 2B and 2 g/L Na2SO4 at pH 3 and 100C was prepared
and treated by both membranes in the membrane chromatography process. The
extent of dye removal was decreased to 84-93% for the P81 membrane, which may
be attributable to either salt ion competition or pH influence. By contrast, the ICE
450 supported membrane could attain nearly complete dye adsorption and desorption.

Abstract: In this study, highly porous adsorptive hollow fiber membranes were directly
prepared from chitosan (CS) and cellulose acetate (CA) blend solutions and were
examined for copper ion removal from aqueous solutions in a batch adsorption mode.
Four types of hollow fiber membranes were spun from two CS/CA blends (with a
CS/CA/forming acid ratio of 3/12/85 or 2/18/80) in two types of coagulants (water or
3 wt.% NaOH solution). All the CS/CA blend hollow fiber membranes displayed
sponge-like and macrovoids-free structures, with specific surface areas in the ranue
of 12.2-15.2 m2/g, porosities of 70.4-79.7%, and pore sizes of 0.05-0.2 m,
depending on the CS/CA ratios and the type of coagulants used. Adsorption
experiments showed that the CS/CA blend hollow fiber membranes had good
adsorption capacity (up to 35.3-48.2 mg/g), fast adsorption rates and short adsorption
equilibrium times (less than 20-70 min) for copper ions, and can work effectively at
low copper ion concentrations (< 6.5 mg/L) to reduce the residual level to as low as
0.1-0.6 mg/L in the solution. X-ray photoelectron spectroscopic (XPS) study
confirmed that the adsorption of copper ions on the CS/CA blend hollow fiber
membranes was mainly attributed to the formation of surface complexes with the
nitrogen atoms of CS in the hollow fiber membranes, hence higher CS contents in the
blend hollow fiber membranes rendering the membranes more adsorptive to copper
ions. It was found that the copper ions adsorbed on the hollow fiber membranes can
be effectively desorbed in an EDTA solution (up to 99% desorption efficiency) and
the hollow fiber membranes can be reused almost without loss of the adsorption
capacity for copper ions. (c) 2006 Elsevier B.V. All rights reserved.

Abstract:
In

NaCl
particles
(porogen)
and
gamma-glycidoxypropyltrimethoxysilane (GPTMS) (cross-linking agent) were used
to make chitosan-silica porous hybrid membranes. An optimal chitosan/GPTMS
weight ratio 1: 1 was found to prepare a novel CSG 1.0 membrane. Both macropores
(10.72-202.29 m) in the membrane matrix and micropores (0.008-0.01 m) in the
skeleton of the macropores were observed on CSG1.0. Five compounds, histidine,
glutamic acid, tyrosine, L-DOPA, and p-aminobenzoic acid were individually grafted
onto CSG1.0. They are linked as ligands by genipin for affinity adsorption of
tyrosinase from a crude Agaricus bisporus solution. This study indicates the
p-aminobenzoic acid (ABA) grafted chitosan membrane (CSG-ABA) exhibited the
best sorption capacity on tyrosinase. Only one band on SDS-PAGE gel was found
from the eluted protein of CSG-ABA that identified the selective adsorption of
CSG-ABA on tyrosinase. The behavior of tyrosinase sorption by CSG-ABA
followed pseudo-first order kinetics. The sorption process was exothermal, and the
sorption capacity decreased as the operation temperature increased. The negative
value of the sorption S showed the tyrosinase sorption by CSG-ABA was
enthalpic dominant. This study shows CSG1.0 membrane is suitable to be modified
for bioproduct separation. (c) 2007 Elsevier B.V. All rights reserved.

Abstract: Porous structured chitosan-p-cyclodextrin membranes were synthesized by
354
incorporating P-cyclodextrin polymers as the functional reagent and using
gamma-glycidoxypropyltrimethoxysilane as crosslinking agent. Compared with
chitosan itself, the synthesized membranes showed significant changes in the
molecular constitutions, crystalline and thermal properties. It was found that the mol
ratio of the epoxy groups of gamma-glycidoxypropyltrimethoxysilane to the free
amino groups of chitosan, as well as the solvent evaporated time, largely influenced
the pore size and water content of the membranes. The effects of the initial
concentration of adsorbate and the pH on the adsorption of hydroquinone were
investigated by the spectrophotometry. Kinetic studies show the adsorption is a
pseudo-second order process. The adsorption is endothermic and chemically
activated reaction with activation energy of 70.0 kJ mol-1. (c) 2008 Elsevier B.V. All

Abstract: Response surface methodology based on a five-level, five-variable central
composite rotatable design was used to model the average diameter of electrospun
poly(methyl methacrylate) nanofibers. The effects studied include polymer
concentration, distance, temperature, flow rate, and voltage. Fiber diameter was
correlated to these variables by using a second-order polynomial function at a 95%
confidence level. The analysis confirmed that polymer concentration, temperature,
flow rate, and voltage were the significant factors affecting the diameter with the first
three being the most significant ones. Also, no interaction effect terms were found to
be significant. The coefficient of determination of the model was found to be 0.9443.
The predicted fiber diameters were in agreement with the experimental results. The
adequacy of the model was examined using additional independent experiments that
were not employed in the model generation to fabricate 100-500 nm fibers with the
average absolute relative deviation being 3.55%. A minimum fiber diameter of 36
nm was established and could be validated by experiments. When used for
immobilization of Candida rugosa lipase by adsorption, the nanofibrous membranes

provided enzyme loading as high as 332 mg lipase/g fibers, which is 5.2 times the
reported maximum value. (C) 2009 Elsevier B.V. All rights reserved.

Abstract: This work investigated the removal of nickel ions from aqueous solutions and
activated sludge by employing ultrafiltration (UF) membranes together with natural
aluminosilicate minerals (bentonite, zeolite and vermiculite). The performance of the
system was examined with respect to different parameters including the membrane
nominal pore size, the temperature and pH of aqueous solution and sludge, the
mineral type and concentration, the sludge MLSS concentration, the Ni(II) initial
concentration and the metal-mineral contact time. The experiments were conducted
in a batch ultrafiltration unit with constant initial Ni(II) concentration of 320 mg/l.
The addition of 15 g/l of bentonite and 15 g/l of vermiculite at pH 6 resulted in Ni(II)
removal efficiencies of 65.3% and 80.0% respectively due to sorption induced by
minerals and sludge. The addition of 10 g/l vermiculite at pH 8 resulted in the
production of a final effluent with Ni(II) concentration that met the EPA short-term
effluent reuse limit of 2.0 mg/l. The processes involved in the removal of nickel
consisted of biosorption onto sludge flocs, adsorption onto the mineral, retention of
insoluble metal ions by the UF membranes and chemical precipitation. High
temperatures, sludge MLSS concentrations and pH values favoured the nickel
removal process. Film diffusion was important at the early stages of the process,
while intraparticle diffusion was dominant at the later stages. The equilibrium
isotherms for the minerals followed the Langmuir model, while sludge followed the
Freundlich model. (C) 2010 Elsevier B.V. All rights reserved.

Abstract: By traditional theories, direct quotations are attempts to reproduce speech
verbatim. By an alternative demonstration theory, they are attempts to depict
selective aspects of the original. So according to traditional theories, direct
quotations should be used only for verbatim reproduction, but according to the
demonstration theory, they can be used for stylistic reasons independent of verbatim
accuracy. In a comparison of these theories, people were asked to recount what
happened in videotaped dialogues under instructions either to be accurate or to
entertain - after one viewing or after memorizing the dialogue. After one viewing,
narrators were no more accurate in direct than in indirect quotation, regardless of
instruction. After memorization, they produced verbatim quotations when asked to
be accurate on the dialogue, but were quite inaccurate when asked to entertain. These
and other findings favor the demonstration theory.

Abstract: Background: The Lancet recently declared that it intends to “make mental
health one of its campaign focal points’’. However, it has been silent on the role it
might play in disseminating mental health research. Aims: To examine The Lancet’s
track record in publishing mental health research relative to its disease burden.
Methods: Research articles (n = 733) published in The Lancet over a 2.5 year period
(2003-2005) were coded according Global Burden of Disease (GBD) classification
system and compared with data from the 2002 GBD study. A range of other
characteristics including whether consumers were involved in the research process
were coded. Results: Mental health articles (excluding neurological and substance
abuse) accounted for 1.8% of articles but are responsible for a worldwide YLD of
22.8% (25.4% high income countries) and DALYs of 9.0% (14.7% in high income
countries). Conclusion: Despite its commendable mental health advocacy work,
mental health research is under-represented in The Lancet. The journal should take
steps to ensure that the dissemination of mental health research is not a neglected
aspect of their advocacy activities.

Abstract: The adsorption of Fe(III) ions from the aqueous solution model using olive
cake as an adsorbent has been investigated. The influences of the initial pH,
temperature, contact time and dosage of the adsorbent on adsorption performance
have been experimentally verified by a batch method. The adsorbent used in this
study exhibited a good adsorption potential at initial pH 4.5 for temperatures 28, 35
and 45C. The removal efficiency and distribution coefficient have also been
determined for the adsorption system as a function of dosage of the adsorbent. The
experimental results are described by Langmuir, Freundlich and
Dubinin-Kaganer-Radushkevich (DKR) isotherm models. Experimental results show
that the kinetic model of pseudo-second order provided a good description of the
whole experimental data more than the kinetic of the Lagergren-first order.

determined and the adsorption behavior was analyzed. Kinetic pseudo-second order
and Langmuir-Freundlich models were successfully applied to the experimental
results, indicating chemisorption on a heterogeneous material. The regeneration of
the material was best accomplished by using a H2O2 solution. The sorption capacity
of the Fe-zeolitic tuff increased when the saturated samples were treated with a H2O2
or FeCl3 solution.

health risks related to mercury/amalgam discharge from dental offices. Journal of the
Michigan Dental Association, 78 (2), 32-36.
Abstract: Mercury is a toxic and bioaccumulative metal. It exists in elemental, inorganic
and organic forms. The use of mercury by the dental profession represents
approximately 6 percent of the total annual domestic consumption and is estimated to
contribute significantly to the discharge of mercury (14 percent in one study) to
waste-water streams. Publicly owned treatment works (POTW) must obtain and
comply with a National Pollutant Discharge Elimination System waste-water
discharge permit. When minimal mercury discharge limits into surface waters are
exceeded, an upstream search for contributors of mercury to the waste stream may
result. Given the present sociopolitical environment, mercury discharge from dental
offices will increasingly receive scrutiny. Strategies to minimize discharge of
mercury/amalgam waste include engineering controls such as changes in the
discharge process, changes in the composition of commercial products, and changes
in control equipment. Governmental strategies include an outright ban, the setting of
discharge standards, and educational efforts. Study of these strategies with evaluation
of effectiveness is needed.

metal binding to microbial surfaces. Journal of Microbiological Methods, 11 (2),

Full Text: J\J Mic Met11, 95.pdf
Abstract: A method is described for the rapid and semi-quantitative assessment of the
extent of metal ion binding to microbial cell surfaces. The technique is based on the
affinity of such surfaces, which are predominantly anionic (by virtue of carboxyl,
phosphate and other exposed groups), for binding cationic dyes, and on the ability of
exogenous metal ions in solution to compete with and reverse dye binding. Thus,
Janus Green bound to intact cells of Pseudomonas cepacia is readily displaced by one
of several metal ions. For Cu, dye displacement is rapid (<1 min) and is a function of
the amount of bound metal (as determined by atomic absorption spectroscopy) at
added Cu concentrations up to 2 mM. The nethod is applicable to other
Gram-negative and Gram-positive bacteria and to yeast. In general, the order of
efficacy of metal ions in displacing dye is Pb2+ > Cd2+ > Cu2+ > Ni2+ > Co2+ and, for
the transition metals, is in accord with the Irving-Williams series. The method is
readily scaled down and allows measurement of metal-induced dye displacement
from cells in a single colony from solid medium. The advantages and limitations of
the procedure are discussed and its wide applicability in biosorption studies
proposed.

Abstract: At this time the European Union regulations require that the heterotrophic
plate counts (HPC) of mineral waters be assessed at two recovery temperatures: 22
degreesC for 72 h and 37 degreesC for 24 h. This procedure is time consuming and
expensive. Development of new rapid methods for microbiological assessment of the
microbial flora in the bottled water is an industry-driven need.
The objectives of this work were to develop a method for the HPC that utilises only one
recovery temperature and one incubation period and evaluate the use of. the
LIVE/DEAD(R) BacLight(TM) Bacterial Viability Kit, 5-cyano-2,3-ditotyl
tetrazolium chloride (CTC) and impedance methods to enumerate viable bacteria in
bottled mineral water.
Results showed that incubation at 30 degreesC could be used instead of incubation at 22
degreesC and 37 degreesC. Good correlation exists between counts at 30 degreesC
and counts at 22 degreesC (r > 0.90) and all the pathogens important in mineral water
analyses grow similarly at 30 degreesC and 37 degreesC during 24 h.
It was demonstrated that impedance methods might be useful to the mineral water
industry as a rapid indicator of microbiological quality of the water.
Results obtained with BacLight and CTC were similar to those obtained with plate
counts. (C) 2001 Published by Elsevier Science B.V.

Full Text: J Mic Met60, 1
Abstract: Sequence retrieval from single bands of polymerase chain reaction
(PCR)-denaturing gel electrophoresis (DGE) profiles is an important but often
difficult step for molecular diversity analysis of complex microbial communities
such as activated sludge systems. We analyzed the temperature gradient gel
electrophoresis (TGGE) profiles of PCR-amplified 16S rDNA fragments from an
activated sludge sample of a coking wastewater treatment plant. Single bands were
excised, and a clone library was constructed for each. Sequence heterogeneity in
each single band was found to be significantly overestimated due to single-stranded
DNA (ssDNA) contamination formed during the PCR amplification, since only
10-60% of library clones of each single TGGE band had identical migration behavior
compared with the parent band. Three methods, digestion with mung bean nuclease,
365
optimization of PCR amplification, and purification via denatured polyacrylamide
gel electrophoresis (d-PAGE), were compared for their ability to minimize ssDNA
contamination, with the last one being the most efficient. After using d-PAGE to
minimize ssDNA to a nearly nondetectable level, 70-100% of library clones for each
single TGGE band had identical migration compared with the parent band. Several
sequences were found in each of six single bands, and this co-migration could be
predicted with the Poland software. The predominant bacteria of the activated sludge
were assessed via a combination of sequence retrieval from each single TGGE band
and band intensity analysis. Only beta and alpha subclasses of the Proteobacteria
were detected, 93.8% and 6.2%, respectively. Our work suggests that prior to
constructing a clone library to retrieve the actual sequence diversity of a single DGE
band, it is advisable to minimize ssDNA contamination to a nondetectable level. (C)

Abstract: This study examines the effect of pH, temperature, metal ion concentration
and culture density on metal biosorption by the nuisance cyanobacterium Microcystis
aeruginosa. Ni biosorption was higher at pH 9.2 than at neutral and acidic pH. In
contrast the biosorption of Cu and Zn was maximum at pH 7.0. However,
biosorption of Zn was difficult to measure at pH values 9.2 and 10.5, owing to the
formation of insoluble complexes. All the test metals (Cu, Zn, and Ni) showed
maximum biosorption rate at low culture densities of 40 mg dry wt l-1. The
biosorption of Cu, Zn, and Ni was maximum at 40C. However, no worthwhile
difference in Zn and Ni sorption was noticed at 4 and 29C as compared to 40C. of
these three metals used Microcystis showed a greater binding capacity (K-f value =
0.84, Freundlich adsorbent capacity) and accelerated biosorption rate for Cu under
various environmental conditions. Fitness of mathematical models on metal
biosorption by Microcystis confirmed that the biological materials behave in the
same way as physical materials. These results suggest that before using a biosorbent
for metal recovery, the environmental requirements of the biosorbent must be
ascertained.

Abstract: The kinetics of copper ion biosorption by Pseudomonas stutzeri cells
immobilized in alginate was investigated. During the first few minutes of the metal
uptake, the copper biosorption was rapid, and then became progressively slower until
an equilibrium was reached. At a biomass concentration of 100 g/l, the copper
biosorption reaction reached approximately 90% of the equilibrium position within
30 min. A Freundich-type adsorption isotherm model was constructed based on
kinetics with different amounts of biomass. When using this model, the experimental
values only agreed well with the predicted values in a solution containing less than
200 mg/l Cu(II). Desorption of the bound copper ions was achieved using electrolytic
solutions of HCl, H2SO4, EDTA, and NTA (0.1 or 0.5 M). Metal desorption with 0.1
M NTA allowed the reuse of the biosorbent for at least ten consecutive
biosorption/desorption cycles, without an apparent decrease in its metal biosorption
capability. A packed-bed column reactor of the immobilized biomass removed
approximately 95% of the metal in the first 30 liter of wastewater [containing 100
mg/l Cu(H)] delivered at a rate of 20 L/day, and, thereafter, the rate gradually
decreased.

Abstract: Biosorption technology is recognized as an economically feasible alternative
for the removal and/or recovery of metal ions from industrial wastewater sources.
However, the structure of biosorbents is quite complex when compared with
synthetic ion-exchange resins,which makes it difficult to quantify the ion-binding
sites. Accordingly, this report describes a well-defined method to characterize the pK
values and numbers of biomass functional groups from potentiometric titration data.
When the proposed method was applied to Sargassum polycystum biomass as a
model biosorbent, it was found that the biomass contained three types of functional
groups. In addition, the carboxyl group (pK= 3.7±0.09) was found to be the major
binding sites (2.57±0.06 mmol/g) for positively-charged heavy-metal ions.

Abstract: The aim of this work was to investigate the adsorption isotherm and kinetic
model for the biosorption of lead (Pb2+) by Rhodotorula aurantiaca and to examine
the environmental factors for this metal removal. Within five minutes of contact,
Pb2+ sorption reached nearly 86% of the total Pb2+ sorption. The optimum initial pH
value for removal of Pb2+ was 5.0. The percentage sorption increased steeply with
the biomass concentration up to 2 g/l and thereafter remained more or less constant.
The Langmuir sorption model provided a good fit throughout the concentration range.
The conformity of these data to the Langmuir model indicated that biosorption of
Pb2+ by R. aurantiaca could be characterized as a monolayer, single-site type
phenomenon with no interaction between ions adsorbed in neighboring sites. The
maximum Pb2+ sorption capacity (q(max)) and Langmuir constant (b) were 46.08
mg/g of biomass and 0.04 l/mg, respectively. The pseudo second-order equation was
well fitted to the experimental data. The correlation coefficients for the linear plots of
t/q against t for the second-order equation were 0.999 for all the initial concentrations
of biosorbent for contact times of 180 min. The theoretical q(eq) value was very
close to the experimental q(eq) value.

Abstract: Nine newly isolated mushroom strains were tested to assess both their zinc
tolerance and potential for zinc removal from an aqueous solution. Four strains of
ectomycorrhizal fungi, namely Clavariadelphus truncatus (T 192), Rhizopogon
roseolus (T 21), Lepista nuda (T 373), and Tricholoma equestre (T 174), along with
five strains of white rot fungi, Lenzites betutina (S 2), Trametes hirsuta (T 587),
Ganoderma spp. (T 99), Polyporus arcularius (T 438), and Ganoderma carnosum (M
88), were investigated using zinc-amended solid and liquid media. Their biosorption
properties were also determined. The colony diameter and dry weight were used as
tolerance indices for fungal growth. C truncatus and T equestre were not strongly
inhibited at the highest concentrations of (225 mg/l) zinc in solid media. The most
369
tolerant four strains with solid media, C truncatus, G carnosum, T hirsuta, and T
equestre, were then chosen for tolerance tests in liquid media. An ectomycorrhizal
strain, C. truncatus, was also detected as the most tolerant strain in liquid media.
However, the metal-tolerant strains demonstrated weak activity in the biosorption
studies. In contrast, the highest biosorption activity was presented by a more
sensitive strain, G carnosum. In addition, seven different biosorbent types from G
carnosum (M 88) were compared for their Zn (II) biosorption in batch experiments.

Abstract: The Journal Citation Reports (JCR) of the Science Citation Index (SCI),
published by the Institute of Scientific Information (ISI), provides a comprehensive
database for analysis of journals. Recent use of JCR’s journal impact factor for
evaluation of journals and authors has provoked strongly mixed reactions among
investigators. This paper examines the effects of the rapidly expanding literature on
the impact factor over the past decade and examines the limitations of journal impact
factor for evaluating individual author’s contributions. The JCR analyzed 6088
journals in 2005, a 32% increase in new listings since 1995. During the same period,
there was a 39% increase in new journal listings in the infectious diseases category.
The phenomenon of journal proliferation has had a profound effect on the journal
impact factor. During the past decade an increased impact factor was observed in
92% of the top ranking major journals, especially in young and rapidly expanding
research fields. Certain highly cited new journals published primarily review articles
- not original contributions. There was no increase in impact factor among some of
the best known journals, such as Journal of Experimental Medicine, Proceedings of
the National Academy of Sciences (USA), and Journal of Infectious Diseases.
Clearly, journal impact factor is an imperfect tool for measuring the quality of
articles, and its use in evaluating authors has inherent risks. In spite of its limitations,
journal impact factor can be used as a rough indicator of scientific quality in specific
subject categories and for serious reading and learning.

of heavy metal cadmium. Journal of Mineralogical and Petrological Sciences, 102

Abstract: The Xiangtan manganese deposit (XTM) was formerly considered a
supergene oxide manganese deposit in South China. Here, we report upon a new
identification of naturally outcropping cryptomelane from the XTM, rather than
psilomelane and pyrolusite, as it was previously considered. Most crystals in
aggregates of XTM cryptomelane are acicular, with a diameter from 20 nm to 120
nm. There are large pseudotetragonal tunnels in the cryptomelane formed by [MnO6]
octahedral double chains with an aperture of 0.4620.466 nm2. The importance of
our find relates not only to manganese resource prospecting in South China, but also
to the application of the octahedral molecular sieve of cryptomelane. On the basis of
the study of some mineralogical characteristics, experiments on heavy metal
cadmium adsorption have been done. The overall adsorption capacity of
cryptomelane for Cd2+ with different electrolytes showed an increase with a pH rise
from 3 to 11.5. This work also showed that in addition to an ion exchange with H+,
the adsorption of Cd2+ might involve exchange with Mn and K cations in the
cryptomelane structure. Isotherms for Cd2+ adsorption in about neutral pH solutions
can be satisfactorily represented by the Langmuir expression and the theoretic
maximum disposal capacity thus determined is 5.54 mg/g.

Abstract: To assess differences between laparoscopic hysterectomy performed with or
without robot-assistance, we performed metaanalyses of 5 key indices strongly
associated with societal and hospital costs, patient safety, and intervention quality.
The 5 indexes included estimated blood loss (EBL), operative time, number of
conversions to laparotomy, hospital length of stay (LOS), and number of
postoperative complications. A search of PubMed, Medline, Embase, and Science
citation index online databases yielded a total of 605 studies. After a systematic
review, we proceeded with meta-analysis of 14 articles for EBL, with a summary
effect of -0.61 (95% confidence interval [CI], -42.42 to 46.20); 20 for operative time,
with a summary effect of 0.66 (95% Cl, -15.72 to 17.04); 17 for LOS, with a
summary effect of -0.43 (95% CI, -0.68 to -0.17); 15 for conversion to laparotomy
(odds ratio, 0.50; 95% CI, 0.31 to 0.79 with a random model); and 14 for
postoperative complications (odds ratio, 0.69; 95% Cl, 0.43 to 1.09 with a random
model). In conclusion, compared with traditional laparoscopic hysterectomy,
robot-assisted laparoscopic hysterectomy was associated with shorter LOS and fewer
postoperative complications and conversions to laparotomy; there were no
differences in EBL and operative time. These results confirm that robot-assisted
laparoscopy has less deletorious effect on hospital, society, and patient stress and
leads to better intervention quality. Journal of Minimally Invasive Gynecology (2011)

Abstract: Carbon anode dust (CAD) is metallurgical waste material of aluminium
production industry. The objective of this study was to convert carbon anode dust to
acetic acid-modified and KOH-modified carbon adsorbat. Modified and unmodified
carbon anode dust samples were characterized by SEM analysis. Pore volume, pore
size and surface area were determined with BET method. The prepared carbons were
evaluated for their adsorption capacity of nickel ions. The experimental data were
analyzed by Freundlich and Langmuir isotherms. Changes in the surface morphology,
surface area properties and obtained adsorption capacity indicate that acetic acid is a
better modifier than KOH. Equilibrium results showed that acetic acid modification
increased the CAD adsorption capacity for Ni (II) more than KOH modification.

Markov Models in computational biology: Applications to protein modeling. Journal
of Molecular Biology, 235 (5), 1501-1531.
Full Text: J\J Mol Bio235, 1501.pdf
Abstract: Hidden Markov Models (HMMs) are applied to the problems of statistical
modeling, database searching and multiple sequence alignment of protein families
and protein domains. These methods are demonstrated on the globin family, the
protein kinase catalytic domain, and the EF-hand calcium binding motif. In each case
the parameters of an HMM are estimated from a training set of unaligned sequences.
After the HMM is built, it is used to obtain a multiple alignment of all the training
sequences. It is also used to search the SWISS-PROT 22 database for other
sequences that are members of the given protein family, or contain the given domain.
The HMM produces multiple alignments of good quality that agree closely with the
alignments produced by programs that incorporate three-dimensional structural
information. When employed in discrimination tests (by examining how closely the
sequences in a database fit the globin, kinase and EF-hand HMMs), the HMM is able
to distinguish members of these families from non-members with a high degree of
accuracy. Both the HMM and PROFILESEARCH (a technique used to search for
relationships between a protein sequence and multiply aligned sequences) perform
better in these tests than PROSITE (a dictionary of sites and patterns in proteins).
The HMM appears to have a slight advantage over PROFILESEARCH in terms of
lower rates of false negatives and false positives, even though the HMM is trained
using only unaligned sequences, whereas PROFILESEARCH requires aligned
training sequences. Our results suggest the presence of an EF-hand calcium binding
motif in a highly conserved and evolutionary preserved putative intracellular region
377
of 155 residues in the -1 subunit of L-type calcium channels which play an
important role in excitation-contraction coupling. This region has been suggested to
contain the functional domains that are typical or essential for all L-type calcium
channels regardless of whether they couple to ryanodine receptors, conduct ions or
both.

frequencies. Journal of Molecular Biology, 281 (5), 827-842.
Full Text: J\J Mol Bio281, 827.pdf
Abstract: We present here a simple and fast method allowing the isolation of DNA
binding sites for transcription factors from families of coregulated genes, with results
illustrated in Saccharomyces cerevisiae. Although conceptually simple, the algorithm
proved efficient for extracting, from most of the yeast regulatory families analyzed,
the upstream regulatory sequences which had been previously found by experimental
analysis. Furthermore, putative new regulatory sites are predicted within upstream
regions of several regulons. The method is based on the detection of over-represented
oligonucleotides. A specificity of this approach is to define the statistical significance
of a site based on tables of oligonucleotide frequencies observed in all non-coding
sequences from the yeast genome. In contrast with heuristic methods, this
oligonucleotide analysis is rigorous and exhaustive. Its range of detection is however
limited to relatively simple patterns: short motifs with a highly conserved core. These
features seem to be shared by a good number of regulatory sites in yeast. This, and
similar methods, should be increasingly required to identify unknown regulatory
elements within the numerous new coregulated families resulting from measurements
of gene expression levels at the genomic scale. All tools described here are available

Abstract: Bacteriophage PRD1 is a membrane-containing virus with an unexpected
similarity to adenovirus. We mutagenized unassigned PRD1 genes to identify minor
capsid proteins that could be structural or functional analogs to adenovirus proteins.
We report here the identification of an amber mutant, sus525, in an essential PRD1 gene
XXXI. The gene was cloned and the gene product was overexpressed and purified to
near homogeneity. Analytical ultracentrifugation and gel filtration showed that P31 is
a homopentamer of about 70 kDa. The protein was shown to be accessible on the
virion surface and its absence in the sus525 particles led to the deficiency of two
other viral coat proteins, protein P5 and the adsorption protein P2. Cryo-electron
microscopy and image reconstruction of the sus525 particles indicate that these
proteins are located on the capsid vertices, because in these particles the entire vertex
structure was missing along with the peripentonal major capsid protein P3 trimers.
Sus525 particles package DNA effectively but loose it upon purification.
All of the PRD1 vertex structures are labile and potentially capable of mediating DNA
delivery; this is in contrast to other dsDNA phages which employ a single vertex for
packaging and delivery. We propose that this arises from a symmetry mismatch
between protein P2 and the pentameric P31 in analogy to that between the
adenovirus penton base and the receptor-binding spike.

Abstract: Over the last 40 years, JMB has published many thousands of articles, all of
which have been important in some way. Compiling a list of the ‘most important’
however, is an invidious task. Friendships can falter on such an undertaking, but the
institute of Scientific information has provided us with an objective methodology for
‘ranking’ articles, according to the number of times any payer is cited in other
publications. This evaluation can of course be criticised for its bias towards papers
describing novel techniques or methods. Often, the true intellectual milestones may
be found in the reference list of the most cited papers. With increasing age, each
paper also has more time in which to have been cited, and so the group of highest
scoring articles is also dominated by some of the oldest. On the other hand, with
increasing time, papers have an increasing chance of being forgotten, and: the
citation rates of these are therefore also a measure of their persisting importance. On
balance, it does represent a value in some way related to how often that paper has
been used. With many caveats, we present the list of the 100 most cited papers in
JMB over the past 40 years. Many of these papers have helped or influenced both a
great many people, and a great many subsequent advances in molecular biology. (C)

Abstract: Density functional theory (DFT) on the LANL2DZ level was used to optimize
the geometry and electronic structures of MoO3 cluster model before and after water
molecular adsorption on its surface. The electron correlation energies of the
optimized structures were also calculated applying the second order Moller-Plesset
perturbation theory (MP2). The results show that when water molecule was adsorbed
on the model surface, it occupied the vacant site of MO5+, with conformation
transforming from model MoO5H4 to octahedral complex of model MoO5H4 H2O.
Water molecule was adsorbed by the process of n electrons of atom O in water
molecule coordinated with electrons in d orbital of the central Mo atom. During this
process, there was a minimum point on the potential energy surface without passing
any energy barrier for the whole adsorption process. The process was an exothermal
reaction, with adsorption heat -91.39 kJ/mol. The results are significant for studies on
the use, deactivation and reactivation of this deoxidizing cat-alyst.

Abstract: In order to shed some light on the origin of the shifts of the vibrational
frequencies of pyridine adsorbed on metal oxides, ab initio calculations have been
performed. SCF methods may be used to assign and identify the pyridine vibrations
of interest although coupling of certain vibrational modes hamper the interpretation.
The effect of the ligands on the vibrations of pyridine is rather complex. It appeared
that the shifts are mainly due to the direct effect of the ligand on the force constants
and to changes in the extent of coupling with the in-plane bending vibrations of the
hydrogen atoms, and, in case of proton transfer, the N-H grou Protonation, however,
severely influences the geometry of pyridine, which may also have a considerable
effect on the vibrational frequencies.

and catalytic tests: cumene cracking and isopropanol decomposition. IR

evidence that the strength of such sites depends on the metal oxide, being very weak
on MgO and important on TiO2. Formation of hydrogensulfite species or

Abstract: The NO-CO reaction kinetics has been studied on Pd/MgO (1 0 0) model
catalysts at low pressure by a pulsed molecular beam technique. The model catalysts
have been prepared by epitaxial growth of metal clusters in UHV on cleaved MgO
single crystals. Three samples with mean clusters sizes of 2.8, 6.9 and 15.6 nm have
been studied. The reaction products are mainly N2 and CO2. The steady-state reaction
rate has been measured between 150 and 400 degreesC at low pressures (10-9-10-6
Torr). The rate limiting step for the reaction is the dissociation of NO at low
temperature and the adsorption of CO at high temperature. The reaction probability
of NO has been accurately determined, taking into account the reverse spillover of
NO from the MgO support towards the Pd particles. It is shown that in these
conditions the turnover number is not an appropriate parameter to determine the
intrinsic effect of particle size. The intrinsic activity depends not only on particle size
but also on particle shape. The medium sized particles exhibiting mainly (1 1 1)
facets are found to be more active. The largest particles, which exhibit principally (1
0 0) facets, are less active. (C) 2001 Elsevier Science B.V. All rights reserved.

Abstract: Ring-opening polymerization of 2,2-dimethyltriMethylene carbonate (DTC)
has been carried out by using single component rare earth tris(4-tert-butylphenolate)s
(Ln(OTBP)(3)) initiators for the first time. The influences of rare earth element,
solvent, temperature, monomer and initiator concentration as well as reaction time on
the polymerization were investigated. The kinetics indicates that the polymerization
rate is first order with respect to monomer concentration and initiator concentration,
respectively. The overall activation energy of the ring-opening polymerization
amounts to 78.7 kJ/mol. Some living character of the reaction was confirmed by
adding another portion of DTC monomer into an almost completely polymerized
system. PDTC was characterized by H-1 NMR, GPC, IR and DSC. PDTC obtained
has no ether unit which resulted from CO, elimination. DSC data identified two
crystalline modifications and showed some influences of molecular weight on the
melting point and melting enthalpy. Mechanism studies showed that monomer

Abstract: The co-adsorption of isocyanic acid (HNCO) and water (H2O) and their
reaction to ammonia and carbon dioxide on the anatase phase of TiO2 were studied
384
with ab initio density functional theory (DFT) calculations using a cluster model as
well as with in situ DRIFTS investigations and kinetic experiments. We found that
isocyanic acid can in principle adsorb both molecularly and dissociatively on the
TiO2 (101) surface, but the moment at which water gets involved in the process, is
vital for determining the further course of the surface reaction. In the absence of
water, it was found that HNCO can adsorb in molecular form on the TiO2 surface.
Assuming this case to be the first step of the HNCO hydrolysis, the surface HNCO
rearranges into an intermediate complex with a modified N = C = O skeleton. After
decarboxylation water attacks the complex from the gas phase and ammonia is
finally formed. However, when water is present at the beginning of the hydrolysis
reaction, it immediately attacks the -NCO group present at the surface, yielding a
carbamic acid complex, which is further transformed into a carbamate complex.
After decarboxylation an NH2 group remains at the surface. Finally, NH3 is formed
by hydrogen transfer from molecularly adsorbed water at a neighboring titanium
center and the hydrolysis reaction is completed. Since water is always present in
diesel exhaust gas, only the second mechanism is relevant under practical conditions.
Moreover, the calculated energy barrier is lower for the second mechanism compared
to the first reaction pathway. The comparison between the sum of the theoretical
vibrational spectra of the reaction intermediates with the in situ DRIFT spectra also
strongly supports the accuracy of the second reaction pathway. The experimental
investigation of the kinetics of the HNCO hydrolysis on TiO2-anatase revealed a
second order reaction-first order with respect to HNCO and first order with respect to
water, which can only be reconciled with the second mechanism. (C) 2007 Elsevier

Abstract: The present work characterised the equilibrium behaviour of lipases from
Pseudomonas and Humicola immobilised on polypropylene-based hydrophobic
support Accurel EP100. The support capacity for both lipases was evaluated, and
activities of immobilised lipases were assayed. Also, the stability of immobilised
lipases was tested. Experimentally, the adsorption isotherm for each lipase was
produced and the activity of immobilised lipase was assayed by esterification of oleic
acid and octanol. Also, immobilised lipase activities, using different support particle
sizes and masses, were assayed. The immobilised lipase stability was tested by a
series of successive esterifications done on the same immobilised lipase sample.
Analytically, the lipase adsorption isotherm was modelled by the Langmuir and
Freundlich formulas. It was found that lipase PS exhibited the Freundlich behaviour,
which suggests multilayer adsorption, while lipolase 100L reflected the Langmuir
formula, i.e. formed a monolayer. Also, Accurel EP100 capacities for lipase PS and
lipolase 100L were 4500 mg (1.35105 LU) and 1200 mg (1.20105 LU),
respectively for each gram of support. It was also found that the activity of lipase PS
initially increased with loading and then levelled off, while it continued to increase
with loading of lipolase 100L. Moreover, lipase activity decreased with mean particle
diameter increase. Stability studies showed that lipase PS guarded its activity to more
than 60% for more than 8 runs. Lipolase 100L showed the same behaviour.

Abstract: Decolourisation of Remazol Brilliant Blue R, an azo textile dyestuff, by crude
filtrate of Funalia trogii ATCC 200800 growing in solid-state fermentation (SSF)
medium containing wheat bran and soybean hull was studied. Optimum pH and
temperature for laccase and horseradish like peroxidase (HRP) production in SSF
medium were determined at 5 and 30 °C, respectively. Maximum enzyme synthesis
was found in 10 days old cultures. We also found Remazol Brilliant Blue R
decolourising enzymatic activity in the culture filtrate of F. trogii. The optimum pH
and temperature for enzymatic decolourisation were determined at 3.0 and 50 °C,
respectively. Both veratryl alcohol and peroxide ions (H2O2) accelerated the
peroxidase enzyme reactions, whereas decelerated the decolourisation of RBBR with
the culture filtrate of F. trogii. Sodium azide (NaN3), cysteine and sodium cyanide
(NaCN) inhibited RBBR decolourising activity, laccase and peroxidase activities.
When sodium metabisulphite (Na2S2O5) was used as an inhibitor, a significant
inhibition of laccase and dye decolourising enzyme activities but no peroxidase
activity was observed. Initial colourless and later orange bands were obtained by the
activity staining process with RBBR and laccase substrate (guaicol), respectively,
after separation by sodium dodecyl sulphate-polyacrylamide gel electrophoresis
(SDS-PAGE). The molecular mass of this band was estimated as about 65 kDa by
SDS-PAGE. Since the reaction was catalysed in the absence of H2O2 as co-substrate,
it was concluded that this enzyme was a laccase.

Abstract: Poly(ethylene glycol dimethacrylate-n-vinyl imidazole) [poly(EGDMA–VIM)]
hydrogel (average diameter 150–200 μm) was prepared copolymerizing ethylene
glycol
dimethacrylate
(EGDMA)
with
n-vinyl

(VIM).
Poly(EGDMA–VIM) beads had a specific surface area of 59.8 m2/g.
Poly(EGDMA–VIM) beads were characterized by swelling studies and scanning
electron microscope (SEM). Cu2+ ions were chelated on the poly(EGDMA–VIM)
beads (452 μmol Cu2+/g), then the metal-chelated beads were used in the adsorption
of yeast invertase in a batch system. The maximum invertase adsorption capacity of
the poly(EGDMA–VIM)–Cu2+ beads was observed as 35.2 mg/g at pH 4.5. The
387
adsorption isotherm of the poly(EGDMA–VIM)–Cu2+ beads can be well fitted to the
Langmuir model. Adsorption kinetics data were tested using pseudo-first- and
-second-order models. Kinetic studies showed that the adsorption followed a
pseudo-second-order reaction. The value of the Michaelis constant Km of invertase
was significantly larger upon adsorption, indicating decreased affinity by the enzyme
for its substrate, whereas Vmax was smaller for the adsorbed invertase. The optimum
temperature for the adsorbed preparation of poly(EGDMA–VIM)–Cu2+-invertase at
50°C, 10°C higher than that of the free enzyme at 40°C. Storage stability was found
to increase with adsorption. Adsorbed invertase retains an activity of 82% after 10
batch successive reactions, demonstrating the usefulness of the enzyme-loaded beads
in biocatalytic applications.

Abstract: Bromophenol blue and methyl orange removal capabilities of citraconic
anhydride-modified horseradish peroxidase were compared with those of native
horseradish peroxidase. Citraconic anhydride-modified horseradish peroxidase
showed higher decolorization efficiencies for both dyes than native horseradish
peroxidase. Upon the chemical modification, the decolorization efficiencies were
increased by 1.8 % and 12.4% for bromophenol blue and methyl orange, respectively.
The quantitative relationships between decolorization efficiencies of dyes and
reaction conditions were also investigated. Experimental data revealed that aqueous
phase pH, reaction time, temperature, enzyme concentration and ratio of dye and
H2O2 play a significant role on the dye degradation. Lower dose of citraconic
anhydride-modified horseradish peroxidase was required than that of native enzyme
for the decolorizations of both dyes to obtain the same decolorization efficiencies.
Citraconic anhydride-modified HRP exhibited a good decolorization of dye over a
wide range of dye concentration from 8 to 24 or 32 mu mol l-1 at 300 mu mol l-1
H2O2, which would match industrial expectations. Kinetic constants for two different
dyes were also determined. Citraconic anhydride-modified horseradish peroxidase
shows greater affinity and catalytic efficiency than native horseradish peroxidase for
both dyes. (c) 2006 Elsevier B.V. All rights reserved.

Abstract: Nearly two decades have passed since the first report about ischemic
preconditioning. Although we do not yet know unequivocally what the final effector
is, we have learned a lot about the signal transduction pathways that result in
protection, and have some good prospects for the final step that results in survival or
necrosis of the ischemic myocardium. Many investigators have contributed to our
current knowledge. We were heartened to learn that four of our JMCC publications
are included in the 20 top-cited papers in the journal’s history. It is gratifying that our
prior publications have generated some interest and stimulated important debate as
documented by the high number of citations by scientists in the bibliographies of
their own papers. In this document, we have been asked to reflect on those four
papers and comment on where they have led us. (c) 2005 Elsevier Ltd. All rights

Abstract: Batch adsorption experiments were carried out for the removal of
ciprofloxacin from aqueous solution using modified coal fly ash as adsorbent. The
effects of various parameters such as contact time, initial solution concentration and
temperature on the adsorption system were investigated. The optimum contact time
was found to be 100 min. The isotherm adsorption data fit well with the Langmuir
model, and the kinetic data fit well with the pseudo-second order and the
intra-particle diffusion model. Intra-particle diffusion analysis demonstrates that
ciprofloxacin diffuses quickly among the particles at the beginning of the adsorption
rocess, and then the diffusion slows down and stabilizes. Thermodynamic parameters
such as ΔG, ΔH and ΔS were also calculated. The negative Gibbs free energy change
and the positive enthalpy change indicated the spontaneous and endothermic nature
of the adsorption, and the positive entropy change indicated that the adsorption
process was aided by increased randomness. (C) 2011 Elsevier B.V. All rights

Abstract: Pore water extract samples derived from six peat types differing in
depositional environment were characterized using pyrolysis GC/FID/FT-IR,
pyrolysis GC/MS, and FT-IR spectroscopy. Pyrolysis GC/FID/FT-IR analysis
revealed many by-products resulting from the thermal degradation of the major
constituents of plant material: cellulose and lignin. Comparison of the pyrolysis
chromatograms showed large variations in the chemical compositions of the
pyrolysis products from sample to sample. Results of the FT-IR analysis revealed
major differences around 1000 cm-1 (C-O stretch region) and between 1500 and 1800
cm-1 (C = C and C = O) stretch region). These two regions have previously been
identified as representing cellulose and lignin, respectively. The six different extracts
are compared based on their resulting FT-IR spectra and pyrolysis chromatograms.
Similarities and differences are emphasized along with any conclusions drawn based
on these studies.

Abstract: The sorption behavior of K10, a type of montmorillonite for trimethoprim
(TMP) drug, was studied by using batch technique under different pH and
temperature. The interaction between K10 and TMP was investigated using SEM,
and FTIR. It was observed that adsorption was increased between pH 2.5 and 6.3. By
393
performing kinetic experiments, the pseudo-second-order kinetic model provides the
best fit for TMP adsorption onto K10 montmorillonite. The sorption of TMP reached
the equilibrium state after 6 h sorption time and has been described by using
Langmuir, Freundlich and Dubinin-Radushkevich equations to obtain adsorption
capacity values. The results indicate that the relative adsorption capacity values (K-f)
are decreasing with the increase of temperature in the range of 298318 K. The
sorption energy values obtained from DR isotherm show that sorption of TMP onto
K10 can be explained by ion exchange mechanism at 298, 308 and 318 K. The
thermodynamic studies were conducted to find the thermodynamic parameters H,
S and G. It was determined that adsorption process is spontaneous and
exothermic in nature. (c) 2006 Elsevier B.V. All rights reserved.

Abstract: The present article describes synthesis, characterization and a detailed
complexation study of calix[4]arene based chemosensor (4) bearing two anthracenyl
units as signaling groups on its coordination sphere. The complex formation ability
of 4 toward selected transition metals such as Cd(II), Co(II), Cu(II), Ni(II) and Pb(II)
has been investigated by UV-visible spectroscopy. Assessment of results reveal that
the chemosensor is selective toward Cd(II) and Cu(II). The FT-IR spectroscopic
method was applied for further confirmation of the complexation phenomenon.
Besides this, a study regarding interference of other metals on complex formation in
solution has also supported the efficient binding preference of 4 for Cd(II) and Cu(II).
From the results it has been concluded that 4 has compatible coordination sphere to
accommodate these metals. The similarities and differences revealed that being soft
nature of both metals and because of diagonal relationship in the periodic table their
coordination behavior toward N/O-donor ligand may be treated as a test on
possibility of the Cu(II) ions to be displaced by Cd(II). The study certainly will help
in understanding the hazards of Cd(II) in biological systems. (C) 2010 Elsevier B.V.

isotherm with the maximum adsorption capacity increasing with temperature from
190 mg g(-1) to 240 mg g(-1). In all experiments the adsorption equilibrium was
attained in 4.5 h. Thermodynamic data showed that MB adsorption onto peat is
endothermic and spontaneous under the experimental conditions employed. Briefly,
peat exhibited rapid adsorption capabilities and high efficiency in removal of MB
from aqueous solution. (C) 2010 Elsevier B.V. All rights reserved.

Abstract: The performance of six density functional theory (DFT) methods has been
tested for a zeolite cluster containing three tetrahedral atoms (3T) and the complexes
it forms with water and methanol molecules. The DFT methods (BLYP, BP86,
BPW91, B3LYP, B3P86, B3PW91) give results in good agreement with
second-order perturbation theory (MP2). The results in this paper provide evidence
of the suitability of DFT methods for studying hydrogen-bonded adsorption
complexes in zeolites. Generally, the hybrid DFT methods are in closer agreement
with experiment and MP2 than the pure DFT methods for geometrical parameters.
The only exception is the Z− geometry, perhaps due to its anionic character. All DFT
396
methods give results in good overall agreement with MP2 for intramolecular
geometrical parameters of the adsorption complexes, intramolecular vibrational
frequencies, and adsorption energies. The B3LYP method gives intermolecular
geometries and intermolecular vibrational frequencies which are closest to those
obtained from the MP2 method. Thus, the B3LYP method seems to be the best
choice for a density functional treatment of molecular adsorption in zeolite systems.

Abstract: Density functional theory on LANL2DZ level was used to optimize the
geometry and electronic structures of MoO3 cluster model before and after water
molecular adsorption on its surface. The electron correlation energies of the
optimized structures were calculated by using the second order Møller–Plesset
perturbation theory. Results show that when the water molecule was adsorbed on the
model surface, it occupied the vacant site of Mo5+; during this process, its
conformation transformed from MoO5H4 model to octahedral complex of model
MoO5H4·H2O. Water molecule was adsorbed by the mechanism of π electrons of
atom O (in H2O) contributing to d orbital of central Mo atom. During this process,
there was a minimum point on the potential energy surface. The process was an
exothermal reaction, with adsorption heat of −91.39 kJ/mol. The results are
significant for studies on use, deactivation and reactivation of this deoxidizing
catalyst.

appearing in the existing music therapy literature. Since then, several other
researchers have continued in this line of inquiry. The purpose of this study was to (a)

Abstract: Adsorp tion at various interfaces has concerned scientists since this
phenomenon underlies a number of extremely important p rocesses of p ractical
significances in industry and environmental p rotection. Many areas in which
technological innovation has covered adsorp tion phenomena have been expanded
more through art and craft than through science. New classes of solid adsorbents and
the imp rovements of the existing ones have been developed and have gained
extreme interest due to their sorp tion p roperties. In recent years considerable effort
has been increasingly directed toward closing the gap between theory and p ractice.
This field of surface science is now generally considered to have become a well
defined branch of physical science rep resenting an interdiscip linary area between
chemistry, physics, biology and engineering. This review p resents in brief the basics
of adsorp tion and adsorp tion separation p rocesses, highlights the p rogress under
the consideration. The relationship between development of adsorp tion theory and
adsorp tion p ractice is pointed out. Our understanding and p ractices pertaining to
adsorp tion and its separation p rocesses on laboratory and on industrial scale are
discussed and illustrated bymeans of a few examp les.

Abstract: This study was carried out to evaluate the environmental application of
modified and nonmodified carbon nanotubes through the experiment removal of
chromium trivalent (III) from water. The aim was to find the optimal condition of the
chromium (III) removal from water under different treatment conditions of pH,
adsorbent dosage, contact time and agitation speed. Multi wall carbon nanotubes
(MW-CNTs) were characterized by field emission scanning electron microscopy
(FE-SEM) and transmission electron microscopy (TEM). The diameter of the carbon
nanotubes produced varied from 20-40 nm with average diameter of 24 nm and 10
micrometer in length. Adsorption isotherms were used to model the adsorption
behavior and to calculate the adsorption capacity of the absorbents. The results
showed that, 18% of chromium (III) removal was achieved using modified carbon
nanotubes (M-CNTs) at pH 7, 150 rpm, and 2 hours for a dosage of 150 mg of CNTs.
The removal of Cr (III) is mainly attributed to the affinity of chromium (III) to the
physical and chemical properties of the CNTs. The adsorption isotherms plots were
well fitted with experimental data.

Abstract: Nanotechnology holds the promise to revolutionize a wide range of products,
processes and applications. It is recognized by over sixty countries as critical for
their development at the beginning of the 21st century. A significant public
investment of over $1 billion annually is devoted to nanotechnology research in the
United States. This paper provides an analysis of the National Science Foundation
(NSF) funding of nanoscale science and engineering (NSE) and its relationship to the
innovation as reflected in the United States Patent and Trade Office (USPTO) patent
data. Using a combination of bibliometric analysis and visualization tools, we have
identified several general trends, the key players, and the evolution of technology
topics in the NSF funding and commercial patenting activities. This study documents
the rapid growth of innovation in the field of nanotechnology and its correlation to
funding. Statistical analysis shows that the NSF-funded researchers and their patents
have higher impact factors than other private and publicly funded reference groups.
This suggests the importance of fundamental research on nanotechnology
development. The number of cites per NSF-funded inventor is about 10 as compared
to 2 for all inventors of NSE-related patents recorded at USPTO, and the
corresponding Authority Score is 20 as compared to 1.8.

Abstract: Text mining is the extraction of useful information from large volumes of text.
A text mining analysis of the global open nanotechnology literature was performed.
Records from the Science Citation Index (SCI)/Social SCI were analyzed to provide
the infrastructure of the global nanotechnology literature (prolific
authors/journals/institutions/countries, most cited authors/papers/journals) and the
thematic structure (taxonomy) of the global nanotechnology literature, from a science
perspective. Records from the Engineering Compendex (EC) were analyzed to
provide a taxonomy from a technology perspective. The Far Eastern countries have
expanded nanotechnology publication output dramatically in the past decade. The
Peoples Republic of China ranks second to the USA (2004 results) in
nanotechnology papers published in the SCI, and has increased its nanotechnology
publication output by a factor of 21 in a decade. Of the six most prolific (publications)
nanotechnology countries, the three from the Western group (USA, Germany, France)
have about eight percent more nanotechnology publications (for 2004) than the three
from the Far Eastern group (China, Japan, South Korea). While most of the high
nanotechnology publication-producing countries are also high nanotechnology patent
producers in the US Patent Office (as of 2003), China is a major exception. China
ranks 20th as a nanotechnology patent-producing country in the US Patent Office.

Abstract: Nanotechnology research has experienced growth rapid in knowledge and
innovations; it also attracted significant public funding in recent years. Several
countries have recognized nanotechnology as a critical research domain that
promises to revolutionize a wide range of fields of applications. In this paper, we
404
present an analysis of the funding for nanoscale science and engineering (NSE) at the
National Science Foundation (NSF) and its implications on technological innovation
(number of patents) in this field from 2001 to 2004. Using a combination of basic
bibliometric analysis and content visualization tools, we identify growth trends,
research topic distribution, and the evolution in NSF funding and commercial
patenting activities recorded at the United States Patent Office (USPTO). The patent
citations are used to compare the impact of the NSF-funded research on
nanotechnology development with research supported by other sources in the United
States and abroad. The analysis shows that the NSF-funded researchers and patents
authored by them have significantly higher impact based on patent citation measures
in the four-year period than other comparison groups. The NSF-authored patent
impact is growing faster with the lifetime of a patent, indicating the long-term
importance of fundamental research.

The
nanotechnology/nanoscience research literature technical structure (taxonomy) was
obtained using computational linguistics/document clustering and factor analysis.
The infrastructure (prolific authors, key journals/institutions/countries, most cited
authors/journals/documents) for each of the clusters generated by the document
clustering algorithm was obtained using bibliometrics. Another novel addition was
the use of phrase auto-correlation maps to show technical thrust areas based on
phrase co-occurrence in Abstracts, and the use of phrase-phrase cross-correlation
maps to show technical thrust areas based on phrase relations due to the sharing of
common co-occurring phrases. The similar to 400 most cited nanotechnology papers
since 1991 were grouped, and their characteristics generated. Whereas the main
analysis provided technical thrusts of all nanotechnology papers retrieved, analysis of
405
the most cited papers allowed their characteristics to be displayed. Finally, most cited
papers from selected time periods were extracted, along with all publications from
those time periods, and the institutions and countries were compared based on their
representation in the most cited documents list relative to their representation in the
most publications list.

Abstract: Nanotechnology research and applications have experienced rapid growth in
recent years. We assessed the status of nanotechnology research worldwide by
applying bibliographic, content map, and citation network analysis to a data set of
about 200,000 nanotechnology papers published in the Thomson Science Citation
Index Expanded database (SCI) from 1976 to 2004. This longitudinal study shows a
quasi-exponential growth of nanotechnology articles with an average annual growth
rate of 20.7% after 1991. The United States had the largest contribution of
nanotechnology research and China and Korea had the fastest growth rates. The
largest institutional contributions were from the Chinese Academy of Sciences and
the Russian Academy of Sciences. The high-impact papers generally described tools,
theories, technologies, perspectives, and over-views of nanotechnology. From the top
20 institutions, based on the average number of paper citations in 1976-2004, 17
were in the Unites States, 2 in France and 1 in Germany. Content map analysis
identified the evolution of the major topics researched from 1976 to 2004, including
investigative tools, physical phenomena, and experiment environments. Both the
country citation network and the institution citation network had relatively high
clustering, indicating the existence of citation communities in the two networks, and
specific patterns in forming citation communities. The United States, Germany,
Japan, and China were major citation centers in nanotechnology research with close
inter-citation relationships.

Abstract: The ability to delineate the boundaries of an emerging technology is central to
obtaining an understanding of the technology’s research paths and commercialization
prospects. Nowhere is this more relevant than in the case of nanotechnology
(hereafter identified as “nano”) given its current rapid growth and multidisciplinary
nature. (Under the rubric of nanotechnology, we also include nanoscience and
nanoengineering.) Past efforts have utilized several strategies, including simple term
search for the prefix nano, complex lexical and citation-based approaches, and
bootstrapping techniques. This research introduces a modularized Boolean approach
to defining nanotechnology which has been applied to several research and patenting
databases. We explain our approach to downloading and cleaning data, and report
initial results. Comparisons of this approach with other nanotechnology search
formulations are presented. Implications for search strategy development and
profiling of the nanotechnology field are discussed.

Abstract: Understanding the toxicity of nanomaterials and nano-enabled products is
important for human and environmental health and safety as well as public
acceptance. Assessing the state of knowledge about nanotoxicology is an important
step in promoting comprehensive understanding of the health and environmental
implications of these new materials. To this end, we employed bibliometric
techniques to characterize the prevalence and distribution of the current scientific
literature. We found that the nano-toxicological literature is dispersed across a range
of disciplines and sub-fields; focused on in vitro testing; often does not specify an
exposure pathway; and tends to emphasize acute toxicity and mortality rather than
chronic exposure and morbidity. Finally, there is very little research on consumer
products, particularly on their environmental fate, and most research is on the
toxicity of basic nanomaterials. The implications for toxicologists, regulators and
social scientists studying nanotechnology and society are discussed.

Abstract: Facilitating cross-disciplinary research has attracted much attention in recent
years, with special concerns in nanoscience and nanotechnology. Although policy
discourse has emphasized that nanotechnology is substantively integrative, some
analysts have countered that it is really a loose amalgam of relatively traditional
pockets of physics, chemistry, and other disciplines that interrelate only weakly. We
are developing empirical measures to gauge and visualize the extent and nature of
408
interdisciplinary interchange. Such results speak to research organization, funding,
and mechanisms to bolster knowledge transfer. In this study, we address the nature of
cross-disciplinary linkages using “science overlay maps” of articles, and their
references, that have been categorized into subject categories. We find signs that the
rate of increase in nano research is slowing, and that its composition is changing (for
one, increasing chemistry-related activity). Our results suggest that nanotechnology
research encompasses multiple disciplines that draw knowledge from disciplinarily
diverse knowledge sources. Nano research is highly, and increasingly, integrative-but
so is much of science these days. Tabulating and mapping nano research activity
show a dominant core in materials sciences, broadly defined. Additional analyses and
maps show that nano research draws extensively upon knowledge presented in other
areas; it is not constricted within narrow silos.

Abstract: China, Russia, and India are playing an increasingly important role in global
nanotechnology research and development (R&D). This paper comparatively
inspects the paper and patent publications by these three countries in the Thomson
Science Citation Index Expanded (SCI) database and United States Patent and
Trademark Office (USPTO) database (1976-2007). Bibliographic, content map, and
citation network analyses are used to evaluate country productivity, dominant
research topics, and knowledge diffusion patterns. Significant and consistent growth
in nanotechnology papers are noted in the three countries. Between 2000 and 2007,
the average annual growth rate was 31.43% in China, 11.88% in Russia, and 33.51%
in India. During the same time, the growth patterns were less consistent in patent
410
publications: the corresponding average rates are 31.13, 10.41, and 5.96%. The three
countries’ paper impact measured by the average number of citations has been lower
than the world average. However, from 2000 to 2007, it experienced rapid increases
of about 12.8 times in China, 8 times in India, and 1.6 times in Russia. The Chinese
Academy of Sciences (CAS), the Russian Academy of Sciences (RAS), and the
Indian Institutes of Technology (IIT) were the most productive institutions in paper
publication, with 12,334, 6,773, and 1,831 papers, respectively. The three countries
emphasized some common research topics such as “Quantum dots,” “Carbon
nanotubes,” “Atomic force microscopy,” and “Scanning electron microscopy,” while
Russia and India reported more research on nano-devices as compared with China.
CAS, RAS, and IIT played key roles in the respective domestic knowledge diffusion.

makes it hard to identify main research directions without a comprehensive literature
overview. This investigation evaluates the impact and structure of the literature in
this field tagging most prolific subjects and articles. Using an optimized search

Full Text: 2010\J Nan Res12, 1.pdf
Abstract: It has been suggested that an important transition in the long-run trajectory of
nanotechnology development is a shift from passive to active nanostructures. Such a
411
shift could present different or increased societal impacts and require new
approaches for risk assessment. An active nanostructure “changes or evolves its state
during its operation,” according to the National Science Foundation’s (2006) Active
Nanostructures and Nanosystems grant solicitation. Active nanostructure examples
include nanoelectromechanical systems (NEMS), nanomachines, self-healing
materials, targeted drugs and chemicals, energy storage devices, and sensors. This
article considers two questions: (a) Is there a “shift” to active nanostructures? (b)
How can we characterize the prototypical areas into which active nanostructures may
emerge? We build upon the NSF definition of active nanostructures to develop a
research publication search strategy, with a particular intent to distinguish between
passive and active nanotechnologies. We perform bibliometric analyses and describe
the main publication trends from 1995 to 2008. We then describe the prototypes of
research that emerge based on reading the abstracts and review papers encountered in
our search. Preliminary results suggest that there is a sharp rise in active
nanostructures publications in 2006, and this rise is maintained in 2007 and through
to early 2008. We present a typology that can be used to describe the kind of active
nanostructures that may be commercialized and regulated in the future.

Abstract: The present article describes a novel synthesis route for nano-sized goethite
(alpha-FeOOH) using hydrazine sulphate as an additive. The X-ray diffraction (XRD)
peaks of synthesized powder matched well with those of alpha-FeOOH.
Transmission electron microscopy (TEM) showed the particles of irregular shape in
the range of 1-10 nm. Batch adsorption experiments for fluoride uptake were
performed to study the influence of various experimental parameters such as contact
time (10 min to 7 h), initial fluoride concentration (10-150 mg L-1), pH (2-11.6) and
the presence of competing anions. The time data fitted well to pseudo-second-order
kinetic model. The fluoride removal passed through broad maxima in pH ranges of
6-8. High adsorption capacity of 59 mg g-1 goethite was obtained. The isothermic
data fitted well to Freundlich model. The presence of other ions namely chloride and
sulphate adversely affected fluoride removal. Fluoride from contaminated water
sample could be successfully brought down from 10.25 to 0.5 mg L-1.

Abstract: Nano-energy, the part of nanotechnology dedicated to the study and
improvement of the Energy Supply Sector, is a promising and perspective research
field. A robust method to quantify international scientific activities in this field is the
literature search. An evaluative bibliometric approach applied to the Science Citation
Index has been done to retrieve a set of articles related to nano-energy and get
knowledge of the direction and trends followed by this particular scientific topic. The
resulting database showed an exponential increase of the number of publications
issuing nano-based investigations in the energy sector in the last decade, accelerating
to an annual growth rate of 1,100%. The most cited articles and the
material-clustering protocol revealed that carbon-nanoelements and their application
in solar energy harvesting and conversion, and energy storage devices have been
principally investigated and represent the main focus in that continuously growing
research field. The number of nanotechnology-related papers in the energy database
increased monotonically for harvesting, conversion, and storage the last decade,
being energy distribution and usage not affected. TiO(2) or SnO(2) nanoparticles or
thin films, and nanocomposites occupied the following top positions in the
investigated material ranking. This trend was constant along the decade, as
confirmed by network analyses. Supported by discipline-clustering, we observed the
fundamental character of the research developed between 2000 and 2009, relying
mainly on material science and chemistry. Hence, further implementation of
nanotechnology findings is needed to stimulate nano-based energy-focused
technologies reaching widespread commercial applications.

Abstract: Ordered nanoporous silica (MSU-H) with high surface area has been utilized
as a solid substrate of a surface-modified hybrid sorbent for the application to the
removal of U(VI). Carboxymethylated polyethyleneimine (CMPEI) with a strong
complexing property has been introduced to the pore surface of MSU-H substrate.
CMPEI-modified MSU-H (CMPEI/MSU-H) has been characterized by scanning
electron microscopy and nitrogen sorption. In a kinetic experiment for 12.5 ppm
U(VI) solution at pH 4.0, 99% U(VI) was removed from solution by the hybrid
sorbent within less than 10 min, indicating that the sorption of U(VI) on the
CMPEI/MSU-H proceeds very rapidly. It was evident that a U(VI) sorption capacity
increased with pH in the range of 2.0 to 4.0. The CMPEI/MSU-H showed a high
sorption capacity of 153 mg/g-sorbent at pH 4.0. In particular, the CMPEI/MSU-H
showed a significantly high uranium loading stability. Only about 1% U(VI) was
released out of CMPEI/MSU-H during 4 months, when the CMPEI/MSU-H was
treated with polyacrylic acid.

Abstract: This paper characterises nanoscience developments in Mexico. A panorama of
the development trends of these emerging sciences in Mexico is presented on the
basis of bibliometric data gathered using different strategies. The results reveal the
nanoscience output trend, which knowledge areas are developing, and which journals
are publishing the articles and also enable us to identify the main institutional actors
involved, and their international collaborations. We have discovered that the most
important collaboration networks are maintained with industrialised countries;
however, collaborative project work outside Mexico is becoming rarer. Lastly we
present our findings on the growth of nanoscience development in Mexico and
so-called emerging countries where we demonstrate that Mexico is at a disadvantage
to its main economic rivals.

Abstract: Ti-containing MCM-48 (Ti-MCM-48) material with mesoporous structure
was synthesized and characterized, and the absorption processes of Co(II) and Ni(II)
on the material were investigated in detail in the present study. The Ti- MCM-48 was
synthesized by hydrothermal reaction and characterized by XRD, FT-IR and nitrogen
sorption methods. Optimum pH value for maximum adsorption rate is 8.0, and the
saturated adsorption capacities of Ti-MCM-48 for Co(II) and Ni(II) are 9.870 and
22.94 mg.g-(1) respectively, which are greater than those of the reported materials
Adsorption isotherms of Co(II) and Ni(II) on Ti-MCM-48 accord well with the
Langmuir adsorption models. Kinetic data of adsorption reactions and the adsorption
equilibrium parameters were also determined, and the obtained data correlated
linearly with the pseudo-second order equation.

Abstract: A recent report by the National Health Federation, a private agency, related
cancer mortality patterns in the United States to fluoridation of water supplies,
triggering much public health concern and some political response. To clarify
theIssues raised, we studied cancer mortality and incidence statistics for U.S.
counties, 1950-69. No trends could be ascribed to the consumption of water that is
artificially or naturally fluoridated.

Abstract: Background: In 1986, the European Organization for Research and Treatment
of Cancer (EORTC) initiated a research program to develop an integrated, modular
approach for evaluating the quality of life of patients participating in international
clinical trials. Purpose: We report here the results of an international field study of
the practicality, reliability, and validity of the EORTC QLQ-C30, the current core
questionnaire. The QLQ-C30 incorporates nine multi-item scales: five functional
scales (physical, role, cognitive, emotional, and social); three symptom scales
(fatigue, pain, and nausea and vomiting); and a global health and quality-of-life scale.
Several single-item symptom measures are also included. Methods: The
questionnaire was administered before treatment and once during treatment to 305
patients with nonresectable lung cancer from centers in 13 countries. Clinical
variables assessed included disease stage, weight loss, performance status, and
treatment toxicity. Results: The average time required to complete the questionnaire
was approximately 11 minutes, and most patients required no assistance. The data
supported the hypothesized scale structure of the questionnaire with the exception of
role functioning (work and household activities), which was also the only multi-item
scale that failed to meet the minimal standards for reliability (Cronbach’s alpha
coefficient greater-than-or-equal-to .70) either before or during treatment. Validity
was shown by three findings. First, while all interscale correlations were statistically
significant, the correlation was moderate, indicating that the scales were assessing
distinct components of the quality-of-life construct. Second, most of the functional
and symptom measures discriminated clearly between patients differing in clinical
status as defined by the Eastern Cooperative Oncology Group performance status
scale, weight loss, and treatment toxicity. Third, there were statistically significant
changes, in the expected direction, in physical and role functioning, global quality of
life, fatigue, and nausea and vomiting, for patients whose performance status had
improved or worsened during treatment. The reliability and validity of the
questionnaire were highly consistent across the three language-cultural groups
419
studied: patients from English-speaking countries, Northern Europe, and Southern
Europe. Conclusions: These results support the EORTC QLQ-C30 as a reliable and
valid measure of the quality of life of cancer patients in multicultural clinical
research settings. Work is ongoing to examine the performance of the questionnaire
among more heterogenous patient samples and in phase II and phase III clinical
trials.

Abstract: Background: Joint replacement with metal implants has been the standard
procedure for surgical treatment of irreversible degeneration of hip and knee joints
for more than two decades, However, reports of local malignancy after joint
replacement and experimental studies that suggest a carcinogenic action of metal
ions and polymethylmethacrylate (an acrylic compound used to stabilize the implant
in the host) have raised concern about the possible long-term risks associated with
metal implants, Purpose: Our aim was to study cancer risk in a Swedish cohort of
patients who had hip replacement surgery during the period 1965 through 1983,
Methods: We studied the risk of cancer in a cohort of 39 154 patients (14 869 men
and 24 285 women), identified in the nationwide Swedish Inpatient Register with at
least one hip replacement during the period 1965 through 1983, The patients were
followed through 1989 by means of record linkage to the Swedish Cancer Register,
The cohort contributed a total of 327 922 person-years at risk, Standardized
incidence ratios (SIRs) were computed using age-, sex-, and period-specific
incidence rates derived from the entire Swedish population, Results: The overall
relative risk of cancer was increased by only 3%, Bone cancer-the focus of previous
concerns-occurred in six cases versus 4.3 expected, and connective tissue cancer
occurred in 28 cases versus 25.9 expected, Increased risks were observed for kidney
cancer (SIR = 1.31, 95% confidence interval [CI] = 1.13-1.51), prostate cancer (SIR
= 1.13, 95% CI = 1.04-1.22), and melanoma (SIR = 1.23, 95% CI = 1.00-1.50), The
relative risk of gastric cancer steadily declined with increasing follow-up time, in
both men and women (SIR = 0.58, 95% CI = 0.39-0.84 more than 10 years after hip
420
replacement). Conclusion: In this study, the largest study to date to evaluate hip
replacement and subsequent cancer risk, the overall cancer risk appears to be
negligible from a public health perspective, and our results have not produced any
strong evidence against the continued use of these devices. Nevertheless, the small
but statistically significant increases in kidney and prostate cancers and the decrease
in gastric cancer deserve further study.

Abstract: Background: The results of several recent epidemiologic studies suggest that
estrogen replacement therapy (ERT) in postmenopausal women may decrease their
risk of subsequently developing colon or colorectal cancer, However, the association
is not clear, as other similar studies have failed to show this inverse relationship,
Purpose: The present study attempts a more definitive analysis of the relationship
between fatal colon cancer and use of ERT among women in a large prospective
study of adults in the United States, Methods: Women were selected for study from
the 676 526 female participants in Cancer Prevention Study II (CPS-II), a
prospective mortality study of about 1.2 million American men and women (from all
50 states, the District of Columbia, and Puerto Rico), begun by the American Cancer
Society in 1982, The median age of the female CPS-II participants was 56 years in
1982, Vital status was determined through December 31, 1989; 630 585 participants
(93.2%) were still alive and 43 862 (6.5%) had died after 7 years of follow-up, Death
certificates were obtained for 96.2% of participants known to have died, At the end
of follow-up, 897 colon cancer deaths were observed in a cohort of 422 373
postmenopausal women who were cancer free at study entry, Cox proportional
hazards modeling was used to compute rate ratios (RRs) and to adjust for other
potential risk factors, The likelihood ratio test (two-sided) was used to determine the
statistical significance of the interaction terms, Results: Ever use of ERT was
associated with significantly decreased risk of fatal colon cancer (RR = 0.71; 95%
confidence interval [CI] = 0.61-0.83), The reduction in risk was strongest among
current users (RR = 0.55; 95% CI = 0.40-0.76), and there was a significant (P =.0001)
trend of decreasing risk with increasing years of use among all users: Users of 1 year
or less had an RR of 0.81 (95% CI = 0.63-1.03), while users of 11 years or more had
an RR of 0.54 (95% CI = 0.39-0.76), These associations were not altered in
multivariate analyses controlling for other risk factors, Conclusions: In our data,
421
estrogen therapy, particularly recent and long-term use, was associated with a
substantial decrease in risk of fatal colon cancer, These results were consistent with
several published studies suggesting a protective role of exogenous estrogens in the
development of colorectal cancer and merit further investigation.

Abstract: BACKGROUND: Some patients with cancer develop antibodies against the
p53 tumor suppressor protein. The presence of these antibodies in serum has been
associated with the expression of mutant p53 by the tumor and in some studies with a
poorer survival. Purpose: The goals of this study were to determine the prevalence of
anti-p53 antibodies in the serum of patients with newly diagnosed small-cell lung
cancer (SCLC) and to assess the clinical relevance of the presence of these antibodies
in the serum, particularly their relationship with tumor response to treatment and
with patient survival.
METHODS: In this prospective study, serum was obtained from 170 patients at the time
of diagnosis of SCLC who were to subsequently receive platinum-or
doxorubicin-based chemotherapy at any one of four hospitals in Barcelona, Spain,
from October 1991 through June 1994. Normal human sera from blood bank donors
(n = 50) served as controls. The presence of anti-p53 antibodies was determined by
western blot analysis with the use of purified recombinant p53 protein. As of January
1996, 96.5% of the patients had been treated and observed in the study, for a median
follow-up time of 33.5 months. Survival was estimated by the Kaplan-Meier method.
Cox proportional hazards regression and unconditional logistic regression analyses
were conducted. All P values resulted from two-sided tests.
RESULTS: Anti-p53 antibodies were detected in the serum of 27 (16%) of the 170
patients studied. None of 50 serum samples from normal individuals contained
anti-p53 antibodies, Analysis of pretreatment clinical characteristics demonstrated
that a weight loss of less than 5% (P = .025), a serum lactic acid dehydrogenase
(LDH) level of less than 450 U/L (P = .002), and limited stage disease (i.e., tumor
confined to one hemithorax, with local and regional lymph node positivity for tumor
cells and/or ipsilateral pleural effusion allowed) (P < .001) were associated with a
statistically significant complete response to therapy, The presence of serum anti-p53
antibodies was not associated with clinical characteristics, such as age (P = .622),
422
functional status (P = 1.0), disease stage (P = .634), complete response to treatment
(P = .572), and survival (P = .492) or with any laboratory parameters including
known prognostic factors in SCLC, such as serum sodium or LDH concentration (P
values of .731 and .246, respectively).
CONCLUSIONS AND IMPLICATIONS: The presence of anti-p53 antibodies in the
serum of patients with newly diagnosed SCLC was not associated with any clinical
characteristics or prognostic markers, suggesting that, in this context, the
measurement of anti-p53 antibodies is not a useful prognostic marker.

Abstract: BACKGROUND: Several epidemiologic studies have suggested that the
consumption of chlorinated drinking water may be associated with the development
of certain cancers in humans. 3-Chloro-4-(dichloromethyl)-5-hydroxy-2
(5H)-furanone (MX), a byproduct of the chemical reactions that occur in chlorinated
drinking water, has been found to be mutagenic in bacteria and mammalian cells;
however, its potential to cause tumors in animals has not been tested previously.
PURPOSE: The objective of this study was to evaluate the carcinogenicity of MX in
rats given MX in their drinking water.
METHODS: MX was administered to male and female Wistar rats (50 rats per dose
group) in drinking water for 104 weeks at concentrations yielding the average daily
doses of MX of 0.4 mg/kg of animal weight (low dose), 1.3 mg/kg (mid dose), and
5.0 mg/kg (high dose) for males and 0.6 mg/kg, 1.9 mg/kg, and 6.6 mg/kg for
females, respectively. Control rats received water from the same source used for
preparation of the MX dose formulations (after its adjustment to the same pH range).
Body weight, clinical signs, and food and water consumption were recorded
regularly. At the end of the treatment period, the animals were killed and full
histopathologic analysis was performed on 47 tissues and all lesions.
RESULTS: Dose-dependent increases in tumor incidence were observed in rats given
MX-containing drinking water; the same MX doses had no obvious toxic effects on
animals. MX consumption increased most drastically the prevalence of follicular
adenoma (up to 43% and 72% in high-dose males and females, a test [one-sided] for
positive trend in all dose groups P = .0045 and P = .0000, respectively) and
carcinoma (55% [P = .0000] and 44% [P = .0000], respectively) in thyroid glands
423
and cholangioma in the liver (8% [P = .0009] and 66% [P = .0000] in the high-dose
males and females, respectively). Among rats given the higher doses of MX in their
drinking water, cortical adenomas of the adrenal glands were increased in both sexes,
alveolar and bronchiolar adenomas of the lungs and Langerhans’ cell adenomas of
the pancreas were increased in males, and lymphomas, leukemias, and
adenocarcinomas and fibroadenomas of the mammary glands were increased in
females. Even the lowest MX dose studied was carcinogenic.
CONCLUSION: MX is a potent carcinogen in both male and female rats, and it causes
tumors at doses that are not overtly toxic to rats.
IMPLICATIONS: Although these findings cannot be extrapolated to humans, MX
should be studied as a candidate risk factor in the possible association between
consumption of chlorinated drinking water and cancer in humans.

therapy in patients with high-risk melanoma: A systematic review and meta-analysis.
Journal of the National Cancer Institute, 102 (7), 493-501.
Abstract: Based on previous meta-analyses of randomized controlled trials (RCTs), the
use of interferon alpha (IFN-alpha) in the adjuvant setting improves disease-free
survival (DFS) in patients with high-risk cutaneous melanoma. However, RCTs have
yielded conflicting data on the effect of IFN-alpha on overall survival (OS). We
conducted a systematic review and meta-analysis to examine the effect of IFN-alpha
on DFS and OS in patients with high-risk cutaneous melanoma. The systematic
review was performed by searching MEDLINE, EMBASE, Cancerlit, Cochrane, ISI
Web of Science, and ASCO databases. The meta-analysis was performed using
time-to-event data from which hazard ratios (HRs) and 95% confidence intervals
(CIs) of DFS and OS were estimated. Subgroup and meta-regression analyses to
investigate the effect of dose and treatment duration were also performed. Statistical
tests were two-sided. The meta-analysis included 14 RCTs, published between 1990
and 2008, and involved 8122 patients, of which 4362 patients were allocated to the
IFN-alpha arm. IFN-alpha alone was compared with observation in 12 of the 14 trials,
and 17 comparisons (IFN-alpha vs comparator) were generated in total. IFN-alpha
treatment was associated with a statistically significant improvement in DFS in 10 of
the 17 comparisons (HR for disease recurrence = 0.82, 95% CI = 0.77 to 0.87; P
< .001) and improved OS in four of the 14 comparisons (HR for death = 0.89, 95%
CI = 0.83 to 0.96; P = .002). No between-study heterogeneity in either DFS or OS
was observed. No optimal IFN-alpha dose and/or treatment duration or a subset of
patients more responsive to adjuvant therapy was identified using subgroup analysis
and meta-regression. In patients with high-risk cutaneous melanoma, IFN-alpha
424
adjuvant treatment showed statistically significant improvement in both DFS and OS.

? Laraque, D., Barlow, B. and Durkin, M. (1999), Prevention of youth injuries. Journal
of the National Medical Association, 91 (10), 557-571.
Abstract: There are four categories of causes responsible for the majority of injuries in
youth 10-19 years of age: 1) motor vehicle traffic; 2) violence (intra-Familial,
extra-familial, self, pregnancy-related); 3) recreational; and 4) occupational. This
article presents data from the National Center for Health Statistics mortality data and
the National Pediatric Trauma Registry morbidity data.
Nationwide, the pediatric injury death rate is highest among adolescents 15-19 years of
age. Motor vehicle-related deaths account for 41% and firearm-related deaths
account for 36% of injury deaths in this age group. For youths aged 10-14 years,
motor vehicle-related deaths account for 38% and; firearm-related deaths account
For 26% of injury deaths. For both age groups, occupant motor vehicle-related
deaths account for the majority of deaths and underscore the need for seat belt use.
Using theoretical principles based on the Haddon matrix and a knowledge of
adolescent development proposed interventions to decrease injuries and deaths
related to motor vehicles and firearms include graduated licensing, occupant restraint,
speed limits, conflict resolution, and gun control. Occupational injuries, particularly
injury associated with agricultural production, account for an estimated 100,000
injuries per year. Preventive strategies include OSHA regulations imposing standards
for protective devices and Further study For guidelines for adolescent work in
agriculture. Injuries related to recreation include drowning and sports injuries.
Preventive strategies may include proper supervision and risk reduction with respect
to use of alcohol/drugs. The data presented support the use of primary prevention to
achieve the most effective, safe community interventions targeting adolescents.

Abstract: Low participation among underserved populations in health research
constrains progress in public health practices. From 2003 to 2005, Women’s Health
Clinic patients at the VCU Health System were recruited to a trial investigating
breast cancer risk communication. In secondary analyses, we examined dimensions
of the recruitment of these diverse women. The sample characteristics (age,
insurance, race and previous mammograms) were compared to the overall clinic. Of
recruitment attempts for eligible women, 45% consented; of those who declined, the
top cited reasons were lack of time (40%) and lack of interest (187.). Of 899
participants, 35% qualified for the indigent care program, compared to 31% of the
overall clinic (P<0.001). Forty-five percent of participants’ were African American,
compared to 54% of overall clinic patients (P<0.001). Participants were younger (50
vs. 53 years, P<0.001) than the overall clinic population. Nonrepresentative
enrollment of patients in clinical trials is common and could lead to suboptimal
applicability of findings. Although there were statistically significant race and age
differences between the study sample and the overall population, we demonstrate
that waiting room recruitment can engage diverse women in a clinical trial and
cancer risk communication.

Abstract: The decolorization kinetics and mechanisms of adsorption of Congo Red
removed from solution by -MnO2 were investigated. The oscillating frequency,
solid load, temperature, pH and initial dye concentration were considered. The
results indicated that the decolorization process obeys the pseudo-second-order
kinetics model. The activation energy for rate-controlled step is equal to 5.1 kJ mol-1.
The rate-controlled step of decoloriza-tion is intraparticle pore diffusion. The high
adsorption capacity and quick velocity makes modified -MnO2 a potential suitable
sorbent for application.

Journal of Nervous and Mental Disease, 198 (8), 529-538.
Abstract: This article reviews the literature on mental health of volunteers after working
in disasters. When mobilized they often are a community’s major source for rescue
and recovery. PsychINFO, PUBMED, and Web of Science were searched for
relevant articles published until October 2009. of 448 articles screened, only 9
articles fulfilled our inclusion criteria. They examined the aftermath of earthquakes
(4 articles), terrorist bombings (1), explosions (1), aviation disasters (1), tsunami (1),
and a bus accident (1). Findings showed that, compared with professional workers,
volunteers tend to have higher complaint levels. The following factors were found to
contribute to mental health complaints of volunteers: Identification with victims as a
friend, severity of exposure to gruesome events during disaster work, anxiety
sensitivity, and lack of postdisaster social support. The review reveals the need for
more research regarding predictors of stress in volunteers.

Abstract: A meta-analysis was conducted to estimate the prevalence of posttraumatic
stress disorder (PTSD) among peacekeepers. A systematic review was carried out
using MEDLINE, Institute for Scientific Information/Web of Science and Published
International Literature on Traumatic Stress databases, leading to a total of 12 studies
reporting PTSD estimates. Pooled current PTSD prevalence was 5.3%, ranging from
0.05% to 25.8%, and a metaregression was used to investigate the variables that
could account for the lack of homogeneity. However, none of the extracted
information was capable of explaining the heterogeneity of the estimates.
Peacekeeping studies presented different methodologies such as several screening
instruments and different times from the deployment to the moment of PTSD
assessment. The wide difference found among those estimates highlights the
importance of the creation of standards for PTSD evaluation among peacekeepers.

Full Text: 2008\J Neu Tra115, 493.pdf
Abstract: The thalamus, a key information processing centre in facilitating sensory
discrimination and cognitive processes, has been implicated in schizophrenia due to
the increasing evidence showing structural and functional thalamic abnormalities.
Glutamatergic abnormalities, in particular, have been examined since glutamate is
one of the main neurotransmitters found in the thalamus. We aimed to review the
existing literature (1978 till 2007) on post-mortem and in vivo studies of the various
components of glutamatergic neurotransmission as well as studies of the glutamate
receptor genes within the thalamus in schizophrenia. The literature search was done
using multiple databases including Scopus, Web of Science, EBSCO host, PUBMED
and ScienceDirect. Keywords used were “glutamate”, “thalamus”, “schizophrenia”,
“abnormalities”, and “glutamatergic”. Further searches were made using the
bibliographies in the main journals and related papers were obtained. The extant data
suggest that abnormalities of the glutamate receptors as well as other molecules
involved in glutamatergic neurotransmission (including glutamate transporters and
associated proteins, N-methyl D-aspartate (NMDA) receptor-associated intracellular
signaling proteins, and glutamatergic enzymes) are found within the thalamus in
431
schizophrenia. There is a pressing need for more rapid replication of findings from
post mortem and genetic studies as well as the promotion of multi-component or
multi-modality assessments of glutamatergic anomalies within the thalamus in order
to allow a better appreciation of disruptions in these molecular networks in
schizophrenia. These and future findings may represent potential novel targets for
antipsychotic drugs to ameliorate the symptoms of schizophrenia.

acute brain injury: A systematic review of animal studies. Journal of Neurochemistry,
115 (4), 806-813.
Abstract: P>Drugs that inhibit histone deacetylase (HDAC) activities have enormous
potential as neuroprotective agents. We performed a systematic review of controlled
animal studies that administered known inhibitors of the zinc-dependent HDACs
before and/or after acute cerebral injury and assessed anatomic/functional outcomes.
Relevant studies were found by searching PUBMED, EMBASE and Web of Science.
From more than 100 identified publications, those data meeting specific criteria were
analyzed using the Cochrane Review Manager software. A beneficial effect of
administering HDAC inhibitors was seen in studies involving cerebral ischemia or
non-ischemic models of acute cerebral injury. Specific studies assessed efficacy
when drug was administered up to 14 days prior to, and 14 days following, the onset
of cerebral injury. This systematic review provides objective evidence of a
neuroprotective role for drugs that inhibit HDACs and highlights particular areas that
require further experimental investigation.
