Student Research Conference 2014
Foreword
We, at Delft University of Technology (TU Delft) welcome you,
talented and excellent bachelor students, to the Student Research
Conference 2014. We are very honoured to host this event and
to show you our campus and research facilities.
At TU Delft, we believe that knowledge generated by research
is fundamentally valuable for education and society. Our students
are inspired by the future and trained to hold positions that allow
them to solve major societal and complex scientific issues. The
transfer of technical and scientific knowledge into innovative product
design arises from state-of-the-art research as conducted at our
University. As you have shown us you are able to match these
expectations we are proud to welcome you at today‟s conference.
We appreciate your courage to present your ambitions by handing
in your research paper.
We are very glad to present two distinguished researchers,
prof. dr. Leo Kouwenhoven and dr. Lotte Jensen, both role
models in their respective discipline.
Prof. dr. ir. Leo Kouwenhoven is full professor of physics at Delft University of Technology. In 2012, he
proved the existence of the Majorana particle, on which his personal research is focussed. He is also
QuTech‟s Director: an institute that combines the knowledge of physics, mathematics and informatics in the
field of quantum computing and quantum internet. Together with Microsoft, he is building a quantum
computer in Delft. Prof. dr. Kouwenhoven will give today‟s first key note lecture.
Dr. Lotte Jensen‟s research focuses on Dutch historical literature, history and philosophy. She pays special
attention to national identity, theater, press history and female authors. Dr. Jensen is co-coordinator of the
research group Europe and Trans (national) Identities (Radboud University) and has worked on several
research projects. Currently, she is involved in the VIDI-project "Proud to be Dutch".
Both researchers have extensive research experience and we are convinced that their presentations will
inspire you in taking your next research steps.
There's a saying that goes as follows: "We teach today's students with yesterday's knowledge for a future we
don't know." This means that connection to research as current knowledge, is essential in our academic
education. Excellent research can change future.
The VSNU Student Research Conference is your stage today, your first step towards a promising research
career. Your presentations at this conference will spark questions and will inspire others to conduct research.
You will be challenged and invited to respond to critical questions of both visitors and fellow researchers. TU
Delft is proud to have you on our stage today.
I hope this day brings you inspiration and interesting insights.

Student Research Conference 2014
Introduction
This is the reader of the fourth Student Research Conference (SRC), hosted in Amsterdam on the 20th of
November 2013. The conference is a combined initiative of Amsterdam University College, University
College Roosevelt and the Association of Universities in the Netherlands (VSNU). The SRC aims to establish
a platform for undergraduate research, or as prof. dr. Henk Meijer, one of the chairs of the review committee
explains:
“The Student Research Conference is an annual conference organised by
the VSNU and hosted by an university in the Netherlands.
The conference aims to increase the visibility of undergraduate research in the
Netherlands (and Flanders) by offering students enrolled in bachelor programmes a place for
presenting and distributing the results of their research.”
Prof. dr. Henk Meijer, University College Roosevelt
The SRC is an annual event that gives bachelor students the unique opportunity to share their research with
a large audience. For the greatest part of the conference students will present their bachelor research, either
in a poster presentation or during a workshop session. During the plenary sessions well-known Dutch
Professors Leo Kouwenhoven and Lotte Jensen will share their enthusiasm for research. Furthermore, there
are many opportunities to discuss the endless possibilities of (undergraduate) research and to enlarge social
and professional networks.
The competitive element of the SRC entails that the student with the best presentation and the most exciting
research will be awarded with the Student Research Award. The final committee attends presentations and
will select the winner as well as the Most Honourable Mention for the runner up. All participants of the SRC
are invited to vote for their favorite poster. The poster with the most public votes will win the SRC Poster
Award.
In this reader you will find practical information concerning the SRC including the program, additional
information about the workshops and the posters, a list of participants and the contact details of the
organisation.
We wish you an inspiring conference.

Interviews keynote speakers
“Find your passion”
Leo Kouwenhoven
Professor Leo Kouwenhoven
will deliver a keynote lecture at the Student Research Conference.
Leo Kouwenhoven is full professor of physics at Delft University of
Technology. In 2012 he discovered the Majorana particle, the focus
of his personal research.
He is also the director of QuTech: an institute that combines physics,
mathematics and informatics in the areas of quantum computing
and quantum internet. In addition, he is building a quantum
computer in Delft together with Microsoft.
Why did you start doing academic research and what made you decide on a career?
I started doing research as part of my physics degree. At the end of my master‟s degree I was truly seized by
research. For my thesis I worked with professor Hans Mooij. We made a discovery which set everything into
motion; I got to talk to famous people and was invited to speak at conferences, which I really enjoyed.
How did you decide to start investigating the Majorana particle?
Sometimes you have your own idea about what you want to research, but in the case of the Majorana
particle it was different. At some point I was in America and I received an e-mail from California, where they
had the theoretical knowledge on how to make Majorana particles. Through previous experiments that I had
published, they found out I had the practical skills needed to actually build the particles. I was an expert in
this area without knowing it myself! I was invited to a meeting organised by Microsoft who funded the project.
The project was exciting and we soon made a plan how we could investigate these particles using my
techniques. From then on it all changed very quickly.
How did your research in the field of quantum computing start?
Microsoft had made the huge discovery that it is possible to use topological properties, as probably present
in Majorana particles, in quantum information. Together we searched for practical implementations. They
had the theory, algorithms and architecture. They just needed someone for hardware implementation.
Coincidentally, I was the one who was already an expert on the subject.
Can you tell something about your current research on the quantum computer?
We need to be able to make qubits without decoherence arising. This means that we can already make
qubits, but it would be a breakthrough if we can construct something around them to ensure that the decay of
the state is precisely under control. Then you could make a lot more of the same bit, and the mistakes that
will always arise will not necessarily lead to the wrong answer in a calculation. We are working on four
different kind of qubits. One is better at storing data, another in processing it. Eventually all four have to work
together in one computer. But not everything always goes according to plan. In our lab we wanted to have
extra set-ups, so we would be able to do more tests at the same time. We discovered, however, that the
amount of water needed for the cooling installation resulted in a pressure in the pipes that was too high. One
of the pipes burst and I had to get a plumber. That was one of those days you do not feel like you are
changing the world.
How long are your qubits stable?
You mean how short! Right now, if I give you the most optimistic number, we have qubits that are stable for
one millisecond. Three years ago this was one microsecond and six years ago one nanosecond. We are
making enormous progress.

Reader
Student Research Conference 2014
What will Microsoft do once there is a quantum computer?
They see the use of the quantum computer in the broad sense and do not want to make a specific product
out of it. What is really getting out of hand is that the amount of data collected every second is too much to
analyse for normal computers, even if you would have all computers in the world available. Microsoft is
looking into different methods to keep this process up and running: big classic computers, parallel
computing, pairing computers via internet or using quantum computers.
At the Student Research Conference, different disciplines are represented. What do you think are the
differences between research in the social and applied sciences?
The difference is that in the applied sciences, for instance physics or chemistry, you can reproduce your
experiments exactly. You do research (you prove a point or develop a product) and the next year someone
else can repeat the same experiment using the same input. In social studies reproducing the same research
is never exactly possible as you work with people and social situations. This does not mean you should not
do research in social sciences. It is very important!
For a physicist it is hard to realise that the conclusions based on a huge database are only relevant for that
specific database. In social sciences this is the standard practice, because if you take another database of
information, for instance from a different year, you will come to different conclusions. It all depends on the
characteristics of the data used for research.
Do you have advice for the young researchers who want to pursue an academic career?
Doing research takes up a big part of your life. It is not a nine to five job, you cannot turn off your e-mail after
five. You should really enjoy it. It is important that you find an area of research that you are good at and feel
at home at. You need to be motivated and passionate, as without this trying to compete with other people in
the field becomes very hard. Find your passion!
At the Student Research Conference students need to present their research in a way that is understandable
for a broad public. What is your advice?
This is something I struggle with sometimes as well. Try thinking of a simple metaphor when you are
explaining complicated information. I was allowed to present for 15 minutes to our Dutch king WillemAlexander. I wanted him to remember my presentation and that he would maybe tell something at home
about it afterwards. So you have to choose the right level of complexity in your presentation: it must be
something that triggers the public and is not too complex. Do not use too many details, that does not stick,
but make sure the information still has substance.
What do you think of doing research during one’s Bachelor’s degree?
I think doing research in the bachelor is not identical to the way I do my research. The period students get is
often too short to learn all the skills and get into the phase where they can get creative and give their own
input. Bachelor research is useful in terms of motivation. Students get the chance to get out of the classroom
and look into different disciplines of research. That motivates!

“The heart of doing research is asking questions and looking for answers”
Lotte Jensen
Lotte Jensen was born in Denmark and grew up in the Netherlands. She is now Associate Professor
of Dutch historical literature at the Radboud University Nijmegen. Besides Dutch historical literature
she studied philosophy and is currently involved in research on national
th
th
th
identity formation in the 17 , 18 and 19 century. She is also a
member of the board of „Werkgroep negentiende eeuw‟ and the
Young Academy.
Currently she is the head of a research project called „Proud to be
Dutch‟, a project on the role of war and propaganda literature in
the shaping of early modern Dutch identity between 1648 and 1815.
For this project literature is used as a cultural historical source
to reconstruct the mentality of the past. Her research focuses on the
way Dutch people used to think about their national identity.
Why did you choose a career in historic Dutch literature and philosophy?
My initial plan was to study English, not Dutch. After my final exams in high school I lived in Spain for a year
to learn Spanish. I wanted to master the language as if it were my mother tongue. However, I soon realised
that I would never be able to comprehend a foreign language just as well as the Dutch language. That was
when I realised that I wanted to study Dutch language and culture. Also, I had really good Dutch teachers at
high school and this caused me to develop a lot of interest in Dutch culture. A good teacher often makes all
the difference in choosing your field of study.
A year after I started my studies in Dutch literature and culture I also took on philosophy. I wanted to do
philosophy because I was intrigued by philosophers. Studying Dutch and philosophy has proved to be a
fruitful combination, as for Dutch you have to read extensively, while philosophy requires reading fewer
books very intensively and precisely.
How did you end up in the academic world?
I always enjoyed learning and reading at school. But it wasn‟t until my studies that I realised I wanted to
continue in historical Dutch literature. I was really passionate about gaining knowledge of old Dutch
literature, for instance, the works of writers like Vondel and Multatuli. I wanted only one thing: to enrich and
extend my own knowledge and transfer that knowledge to other people.
Why did you start doing research into national identity shaping?
I think that to be able to do research you need a fascination that, in some way, has something to do with
yourself. My nationality is Danish and this has shaped my identity, even though the Netherlands is my home.
So, my scientific interest has something to do with my foreign background.
The direction your research takes can be a coincidence. If you are taught by an inspiring teacher, for
example, it could nudge you into that particular direction. I could never have predicted that I would be
involved with Dutch cultural history and literature. Like many other students, I initially began studying Dutch
in order to study modern literature. Students usually don't consider Vondel or Reinaert de Vos in the first
place, but think more of Grunberg and A.F.Th. van der Heijden. You don't choose the path you will take in
advance; that path is created in an inspiring class or by a good teacher.
What do you like about research? What motivates you?
I have a great passion for literature. What motivates me is that you can sort of step into the shoes of writers
from the past. You learn to understand why these texts functioned the way they did and why they had such
an impact. Take a writer like Vondel, his work Gijsbrecht van Amstel is a very complicated play. It
incorporates a classical layer, a mythological layer and a historical layer. It is actually a kind of game to me,
to fathom and understand such a piece. It is a search for knowledge for the sake of knowledge itself; it is a
puzzle you want to solve.
14
Reader
Student Research Conference 2014
What further motivates me, is teaching students. It is inspiring to convey to others the pleasure you get from
unravelling and understanding such a text. It is wonderful to see students become just as enthusiastic about
a text as I am and believe me, no one who starts reading Vondel likes it immediately. As a student you need
help. When I read Vondel for the first time I didn't take to it right away, but I thought it was intriguing: what
does it mean and how is it tied together? Once I am fascinated by something it becomes a challenge to
unravel it.
What is your advice to people who want to become academics?
Do it! Let yourself be led by what you like to do and become very good at that. If you are driven to do
research, follow your passion. If you want to do a PhD, do it, because it enriches the rest of your life. Ignore
your parents‟ advice that you have to find a „real‟ job; follow your passion and become really good at that!
What is your dream?
I would love to do an encompassing publication on Dutch identity throughout the ages. I am saving that for
when I get a bit further in my research, but it is definitely my dream. To write at least one elaborate, large,
historical book that has a real impact. For this you should use the knowledge you have built up through the
years.
Queen Maxima once said that the typical Dutchman does not exist. You think it does. How would you
characterise this person?
In the past, authors have created many stereotypical images of the Dutchman. This Dutchman functions as a
sort of literary weapon in the fight against the enemy. So what I am talking about is a rhetorical character,
one that is created on paper in relation to war enemies, such as Spain and France. This Dutchman does
have a number of specific characteristics: he is hardworking, thrifty, diligent, temperate, tolerant, simple,
liberal-minded, and devout. Some characteristics are not deemed relevant in this current time, while others
are still applicable. In conclusion I can say that THE Dutchman does not exist, but is created by those literary
writings and so, in a sense, does exist but only as a literary and rhetorical weapon against the enemy.
Why do you consider research so important for a Bachelor’s degree?
In your Bachelor studies you lay the basis for further development in your Master studies. If you have no
experience with research in your Bachelor studies then you don‟t know what is like to do research. When
doing research a lot of questions will arise and you will need to find ways to answer these questions. The
heart of doing research is asking questions and looking for answers. Doing research is the basis of your
academic career.

Fast water purification using sunlight
Rick Driessen, University of Twente
Clean water demand is increasing due to pollution of fresh water and climate change. Present techniques to
purify water are not sufficient since they are chemically, energetically or operationally expensive.
Photocatalysis employing TiO2 proves to be a promising technique to purify water. This study investigates
the performance of DC reactive magnetron sputtered TiO2 as photocatalytic layer in a microreactor. A
numerical model was developed that describes the water cleaning reactor accurately. Mass transfer and
reaction rate limitations were investigated. Selected contamination removal was demonstrated within only
tens of seconds.

An Elementary Shallow Cumulus Parameterization for Tropical Boundary Layers
Martin Sikma, Wageningen University
Shallow Cumulus (SCu) convection is a key process in the tropical region, as it has a major impact on the
partitioning of surface fluxes and the dynamics of the lower atmosphere. Since SCu clouds contribute largely
to the spread in the estimation of climate sensitivities, it is essential to represent SCu convection accurately
in numerical weather and climate models. In this paper we propose an improved SCu parameterization
for a tropical situation, since the current one overestimates SCu convection largely (2.4 cm s-1 on average).
With the help of LES and MXLCH modelling we were able to reduce this to an average of 0.2 cm s-1.

One-night stand or long-term relationship? Different make-up preferences in men
Gina Weßel, Maastricht University
Make-up is widely used among women in order to appear more attractive. Current research indicates, that a
moderate amount of make-up is perceived as most attractive by men, however it is not yet clear which
personal factors influence the men‟s evaluation. This study explored the attractiveness ratings of female
faces with different shades of make-up, differentiating between men preferring short- and long-term sexual
relationships (unrestricted and restricted sociosexual orientation respectively). Both groups of men find
natural make-up most attractive and no make-up least attractive. However, it was found, that the raters
sociosexual orientation has a significant influence on perceived attractiveness.

Ethics of Expanded Access to Investigational Drugs During an Epidemic of a Lethal or
Untreatable Illness
Thomas Foets, Utrecht University
The epidemic of the lethal, rapidly spreading HIV virus during the 1980s triggered a tension between society
and regulatory authorities for access to experimental drugs. It is likely that an epidemic of a lethal and
untreatable illness will occur again. The paper explains the fundamentals of expanded access to
experimental medication, followed by arguments used by proponents and opponents of expanded access
and presents a balanced view of the arguments used. Subsequently, the paper presents a framework to
allow expanded access during such an epidemic: a worldwide-expanded access organisation with criteria
ensuring fair access to and distribution of experimental medication.

Selenium Recovery and Stability after Biomineralization
Annemerel Mol, University College Roosevelt
Biomineralization can be used for the removal of toxic selenite as elemental selenium from water. In this
study, formation and properties of selenium (Se) were investigated in anaerobic batch experiments. Selenite
(0.81 mM) was reduced to Se using Emmtec anaerobic granular bacterial sludge. At 30 °C red amorphous
selenium (pH 7.78) and black crystalline needles (pH 8.98) were found. Exposure to air or air combined with
ultrasound treatment leads to 13% oxidation of Se to selenite within a week. Selenite can be efficiently
(>99%) removed by bio-reduction as stable Se, provided it is separated from liquid or is kept under
anaerobic conditions.

Kinetic analysis of sunflower oil conversion to biodiesel
Pieter Plehiers, Marijke Vervenne, Lise Verbruggen and Johannes de Jong, Ghent University
Biodiesel is a renewable fuel that may (partially) replace fossil fuels. Aiming at an economically viable largescale implementation of biodiesel production, an adequate kinetics model constitutes an indispensable tool.
Hence, sunflower oil transesterification with methanol to fatty acid methyl esters has been investigated
experimentally and by kinetic modeling. A compromise between statistical significance and physical meaning
has been pursued while assessing the experimentally observed kinetics via a phenomenological power law
model as well as by more fundamental models. A power law model which specifically accounted for the
catalyst concentration was found to give an accurate reproduction of the experimental data.

Nieuwe Materialen voor stralingsdosimetrie
Andreas Werbrouck, Ghent University
Bij stralingsongevallen is het belangrijk snel de stralingsdosis van de slachto_ers te bepalen. Op die manier
kan een juiste behandeling gestart worden. Gewone burgers dragen gewoonlijk geen gespecialiseerde
dosimeters. Daarom werd in dit onderzoek de geschiktheid van alledaagse materialen als dosimeter
bestudeerd, uitgelezen met elektronen paramagnetische resonantie (EPR). De „klassieke‟ dosimeters
alanine en tandglazuur werden eerst onderzocht. Na onderzoek van fossiel tandglazuur werd een
stralingsdosis geschat, die toelaat een fossiel te dateren. Verder werden kippenbot, eierschalen, twee
soorten kauwgom en rubber uit schoenzolen nader bestudeerd. Dit laatste materiaal werd nog niet eerder
als stralingsdosimeter beschreven.

Minimum electron budget for a maximum result: how to count atoms with single atom
sensitivity using electron microscopy?
Annelies De Wael, University of Antwerp
Recently, a method has been developed for counting atoms in an atomic column from scanning transmission
electron microscopy images [1–3]. Ultimately, the probability for making counting errors should be kept to a
strict minimum. This is the subject of the present paper. Expressions for the probability of error lead to
optimal detector settings, which are significantly di_erent from those traditionally used. In this manner, the
electron dose needed to achieve a pre-specified precision can significantly be reduced. The proposed
methodology drastically improves the atom counting precision, for the same electron budget, opening up
new possibilities to characterise nanomaterials in three dimensions.

The influence of co-existing Poecilia reticulata (Guppy) on Rivulus hartii (Killifish) activity
Naomi Eeltink, HAS University of applied sciences
Changes in foraging behavior may be caused by competition between two or more co-occurring species.
In many cases of competition, species do not interact with one another, but deplete the resources available
to each other. The effects of exploitation may drive a species to better adapt to competition pressure. We
evaluated the change in Killifish (Rivulus hartii) activity in cooccurrence with guppies (Poecilia reticulata). We
conducted day- and nighttime observations at guppy- Rivulus and Rivulus-only sites in two different rivers in
the Northern Range Mountains of Trinidad. We predicted that R. hartii would display more activity after dark
in sites were they co-occur with guppies and that R. hartii would be more active during the day at the
Rivulus-only sites. Our results showed that R. hartii activity, postdisplacement, is diurnal; yet when R. hartii
are found co-occurring with guppies who are mainly active during the day, R. hartii shift their feeding activity
to nocturnal. Furthermore, no differences in R. hartii overall activity between the two rivers were observed,
suggesting that the shift from diurnal to nocturnal activity may be a general phenomenon.

Canopy conductance models: validation for rapidly changing conditions on 1-minute time
scale
Arian van Westreenen, Wageningen University
Plants play a crucial role in land-atmosphere exchange processes. Therefore, the canopy conductance (gc),
simulating the aperture of stomata, is a key-parameter in atmospheric models. The most widely used
parameterisations of gc are the empirical Jarvis-Stewart and the plant-physiological Ags
parameterisations. Nowadays atmospheric models run on increasingly finer resolutions. This paper aims to
validate both parameterisations (including the A-gs submodels) for short time scales. Both parameterisations
were not able to simulate observed responses to rapidly changing conditions. The submodel for internal CO2
concentration was not reproduced realistically. Moreover, the assimilation rate submodel performed well,
although the magnitude was too small.

The interactions of ATP with ATPase active site mimics
Koen van Asseldonk, Radboud University
Hydrolysis of ATP in the active sites of ATPases is a vital process, yet poorly understood on the atomic level.
In this paper, we study the interactions of ATP with F1-ATPase active site biomimics by probing binding
energies and local structures of gas-phase ATP-mimic complexes using collision-induced and infrared
multiple-photon dissociation. Phenomenological binding energies are derived, from which we conclude that
both Glu and Arg residues play a role in binding ATP in the ATPase active site mimics. Moreover, we
measure IR action spectra of a hydrolysis-like fragmenting complex to visualize conformational changes
occurring during this reaction.

Election Pledge Fulfilment in the Netherlands
Ramon van der Does, University College Roosevelt
Why do political parties break their election pledges? And why do they include so many pledges in election
manifestos when they cannot deliver upon them? This research explores the functions of election
manifestos. In addition, it addresses the question what institutional factors influence governing parties‟
pledge fulfillment rates. Data from the Kok II (1998-2002) and Balkenende II (2003-2006) governments in the
Netherlands support the idea that governing parties in parliamentary democracies are likely to include many,
cautiously phrased, pledges in their manifestos. Also, the research confirms earlier findings on what may
facilitate or hinder pledge fulfilment and suggests new factors.

Charity Giving and the Strength of Default Effect
Lenka Habetinova, Tilburg University
In this experiment I test whether defaults, or information about them, affect charitable donations. I find that
their effect is not statistically different from zero and that demographic variables explain most of the variation
in the data. Furthermore, I measure the subjects‟ emotions during the experiment and in contrast to prior
studies relying on self-reported emotions, I conclude that giving does not necessarily make people happier.

Specialisatie in het Secundair Onderwijs: Een Goede Zaak?
Kenneth De Smet, Jennifer Norga and Marieke Van Hecke, Ghent University
Aan de hand van een studie van de internationale wetenschappelijke literatuur onderzoeken we de effecten
van het tijdstip waarop specialisatie plaatsvindt. We vergelijken vroege specialisatie (early tracking) met late
specialisatie (late tracking) aan de hand van twee maatstaven: welk tijdstip van specialisatie bewerkstelligt
gelijkheid van kansen en welk genereert betere leerresultaten of is met andere woorden het efficiëntst.
Deze onderzoeksresultaten linken we aan het onderwijshervormingsplan van de Vlaamse Regering: het
masterplan Secundair Onderwijs 2013. Uit onze studie blijkt dat early tracking voor een betere cognitieve
ontwikkeling zorgt. Daarenboven werd geen causale link tussen specialisatie en sociale discriminatie
gevonden. De resultaten tonen aan dat het hervormingsplan geen optimaal antwoord biedt op de huidige
pijnpunten van het Vlaamse onderwijs. De sectie beleidsadvies toont aan dat de pijnpunten aangepakt
kunnen worden zonder de voordelen van early tracking ten opzichte van late tracking overboord te gooien.

Effectively Protecting Cultural Heritage: Incorporating Cultural Genocide into the
International Legal Definition of Genocide
Sophie Starrenburg, Leiden University College the Hague
International law is unable to effectively protect cultural heritage from malicious destruction, highlighting the
need for proper enforcement mechanisms within cultural heritage law. The protection of cultural heritage can
be secured through the criminalisation of acts of cultural destruction in a manner that recognises the grave
consequences of such destruction upon the lives of individuals. This can best be done by reintegrating the
concept of „cultural genocide‟ within the international legal definition of genocide, given that this concept
acknowledges that groups can be destroyed not only by killing individual group members, but also through
the annihilation of their shared culture.

How Do R&D and Education Austerity Measures Affect Fiscal Sustainability?
Michaël Rubens, Vrije Universiteit Brussel
This paper assesses fiscal policy in industrialized countries by investigating the links between public R&D
and education investments and fiscal sustainability on different time horizons. This allows an investigation of
the effects of austerity measures in both sectors on fiscal outlooks. An extensive literature exists on the
effects of austerity measures on output growth. However, as fiscal policy evaluation gets more important
mainly due to supra-national oversight, it is relevant to research effects on fiscal variables as well.

Gender differences in the relationship between oral communicative competence and peer
rejection: An explorative study in preschool
Femke van der Wilt, VU University Amsterdam
This study investigated gender differences in the relationship between oral communicative competence
(OCC) and peer rejection in preschool. It was hypothesized that children with poorer OCC would be more
often rejected by their peers and that the strength of this relationship would differ for boys and girls. No
relationship was found between OCC and peer rejection. However, a positive relationship was observed
between OCC and peer acceptance, but this relationship only applied to boys. It is suggested that preschool
teachers trying to enhance peer acceptance should take the promotion of OCC into account.

Peer feedback: Are trained students more motivated to provide it?
Kaylee Rosalina, Bas Alderlieste and Samantha Martens, Utrecht University
For students to provide useful peer feedback it is paramount that resistance is reduced and motivation
increased. The self-determination theory of Deci and Ryan (2000) was used to support the hypothesis that
training in feedback skills results in enhancement of students‟ motivation for giving peer feedback through
perceived competence. This hypothesis was tested in an experimental setting. The training did not
significantly affect the motivation to give peer feedback, but did have a positive effect on perceived
competence in peer feedback skills. In conclusion, to enhance motivation instructional designers should
focus more on autonomy and relatedness when creating training material.

Tussen geloof en wetenschap. Georges Lemaître, paus Pius XII en de oerknaltheorie
Alexander van Biezen, KU University Leuven
Georges Lemaître (1894-1966), both priest and physicist, is the founding father of the big bang theory. In
1951, pope Pius XII saw in Lemaître‟s theory a confirmation of the Christian doctrine of creation. Surprisingly
enough, Lemaître opposed this official statement of the pope. According to him, a cosmological theory
cannot be used as a proof nor as a refutation of an article of faith. In my research I investigate which vision
Lemaître had on the relation between religion and science. This research puts the current-day discussion
about religion and science in a surprisingly new light.

Legal Acrobatics: To What Extent Does Family Reunification on the Basis of Directive 2004/38
Amount to Abuse of Law?
Hester Kroeze, Utrecht University
EU-directive 2004/38/EC regulates the free movement of persons in the European Union and protects the
right of all Union citizens and their family members to travel to- and/or reside on the territory of all Member
States of which they do not have the nationality, under favourable conditions. These family members may be
other Union nationals, but they may also be third country nationals1 with or without a permit. The ratio of this
set up is to make cross-border movement within the Union as attractive and easy as possible. An accessory
consequence of this regime is that it offers the possibility to legalize an illicitly residing third country national
family member of a Union citizen, through movement to a Member State of which the latter is not a national.
Moreover, the case law of the European Court of Justice provides for the possibility to „take once acquired
rights back home‟, which allows for the application of U-turn construction to avoid national immigration law –
the so-called „Europe-route‟. This paper adds to the debate on the question whether this behaviour is lawful
or should be addressed as abuse of law. Much angles can be taken, and little conclusive answers can be
given. Nevertheless, several insights on the topic are worthwhile to present.

Cloud Base Height Computation with Stereo Whole-Sky Cameras
Sophie Hermans, Delft University of Technology
In this research a software package is developed, stereo, which calculates the cloud base height using
images from two whole-sky cameras. The problem is over-defined so a point in one image has to lie on a line
in the other image, the so called epipolar line. With a correlation algorithm matching points can be found. By
making use of the restriction of the epipolar line, the computation time of the correlation is greatly reduced.
The results obtained by stereo match with the data from the ceilometer. The measurement uncertainty
becomes larger as the height increases, but for physical realistic heights the accuracy is su_cient.

Modelling band scattering and sandblasting
Anton Atanasov, Hanze University of applied sciences
The SPICA FAR-Infrared Instrument (SAFARI) must be calibrated and characterized by the Optical Ground
SupportEquipment (OGSE). One of the components within the OGSE is an integrating sphere which can
scatter light from 34 µm to 210 µm. This paper reports the development of a fabrication algorithm as well as
the implementation of a light-band scattering simulation. The simulations are evaluated against experimental
data from 30 µm to 65 µm and are used to extrapolate the wavelength band and conditions. It has been
found that the currently available fabrication techniques are incapable of achieving the desired scattering.

The effect of succession of three different caterpillar species on Brassica oleracea,
plant defense divergence or convergence?
Quint Rusman, Wageningen University
Plant mediated competition between herbivore species is important in shaping insect communities. Different
herbivore species induce different plant defenses, and sequence of arrival will be important in shaping plant
defenses. This study used the Brassica oleracea (L) system and three herbivores: Pieris brassicae,
Mamestra brassicae and Plutella xylostella. It was tested if plant phenotypes diverge or converge under
different sequences of attack by the three caterpillar species. It was shown that there was a species specific
effect and an arrival specific effect, which together resulted in a diverging pattern of plant defense under
mixed sequences of arrival.

Driedimensionale celculturen. Een alternatief voor diermodellen in tumor- en drugscreening?
Jolan De Boeck, Quinten Van Avondt, Jiri Dietvorst, and Jore Van Wauwe, University of Antwerp
Driedimensionale celculturen kunnen een oplossing bieden waar 2D in vitro culturen en diermodellen tekort
komen. Multicellulaire sferoïden (MCS) zijn 3D celculturen die dichter aanleunen bij de in vivo
omstandigheden van tumoren. In het kader van dit project werd getracht een MCS cultuur te optimaliseren
door vergelijking van verschillende kweekprocedures. Tevens werd nagegaan hoe deze MCS zich gedragen
na behandeling met antitumorale middelen. Deze studie vormt een eerste aanzet voor toepassingen in
highthroughput screening (HTS), die nodig zijn om statistisch significante effecten van lead compounds in
fysiologisch relevante modellen aan te tonen.

MRI-based contour propagation for cervical cancer: towards MRI-guided adaptive
radiotherapy
Anita Honingh, Utrecht University
Clinical introduction of magnetic resonance imaging (MRI) guided adaptive radiotherapy with the new MRIaccelerator requires automatic contour propagation. In this study we tested a method for (semi-) automatic
contour propagation based on deformable image registration of two MRI scans. We analysed both metric
and dosimetric parameters of agreement between manual and propagated contours. After addition of manual
input, our method for contour propagation shows markedly improved accuracy (metric and dosimetric
parameters) for contour propagation of primary clinical target volume, bladder and rectum, but not for nodal
clinical target volume, bowel and sigmoid.

The Effect of Microbleeds on Functional Connectivity and Brain Network Organization in
Alzheimer Patients
Astrid Alsema, VU University Amsterdam
Alzheimer pathology is thought to be reflected by microbleeds. Microbleeds are small signal voids in echoweighted magnetic resonance images. Microbleeds - or their underlying pathology - could disturb functional
brain activity. Brain activity is measured by electroencephalography (EEG). Functional connectivity measures
derived from EEG time-series were used to construct a novel functional brain network: the minimum
spanning tree. We showed that Alzheimer patients with ≥3 microbleeds have lower functional connectivity
than Alzheimer patients without microbleeds. Current study indicates that Alzheimer patients with multiple
microbleeds might suffer from additional loss of functional connections between neurons compared to
Alzheimer patients free of microbleeds.

Abnormal Volumetric Patterns in Schizophrenia: MRI Findings in Cerebellar and Hippocampal
Structures.
Rik Ubaghs, Maastricht University
Introduction Evidence supports involvement of the cerebellum and the hippocampus in schizophrenia.
The current research investigates volumetric differences between healthy controls and patients.
Method Volumetric measures were obtained from nineteen patients and thirty healthy controls using a 1.5T
MRI scanner. Volumetric differences were examined using F-tests. Cerebrum volume was used as a
covariant. Additionally, Spearman correlations were computed between the structures and cerebrum volume.
Discussion No volumetric Group differences were found. Results did indicated dissimilar Group patterns in
terms of associations between volumes of interest and cerebrum volumes. This suggests possible structural
abnormalities associated with the pathology of schizophrenia.

Avi we-elohi - The Divine Father in Pre-Christian Judaism
Bernice Brijan, University of Groningen & Tilburg University
This paper investigates early Judaism as the foundation of early Christianity. This is done by focusing on the
image of God as a Father. It departs from the famous and highly influential thesis of Joachim Jeremias from
the 1960s, who stated that the way in which Jesus refers to God as his Father points to his unique
relationship with God. It is this thesis that is tested in this paper by an investigation of the textual evidence
from the Dead Sea Scrolls. Contrary to the conclusions of Jeremias, an analysis of these manuscripts which are all dated to approximately the first century BCE at the earliest - makes clear that the image of God
as a Father was certainly present in Second Temple times and that it was interpreted and developed in a
variety of ways. It shows on the one hand that Jesus indeed stood in the Old Testamental tradition of the
paternity of God, but questions at the same time whether he was really that distinctive. The Dead Sea Scrolls
prove to be essential to give a nuanced view of early Judaism and the dawn and development of Christianity.

Knowledge Transmission: Context, Techniques and Control - An Examination of Joachim
Heinrich Campe's "Entdeckung von Amerika" as a Philanthropinist Book for Young Readers
Helen Piel, Maastricht University
This thesis explores Die Entdeckung von Amerika (1781/82) by the German Enlightenment educationalist
Joachim Heinrich Campe (1746-1818). It asks by which means Campe wished to transmit knowledge to
readers and exert control over this transmission with his trilogy covering the discovery of America. The
work‟s examina-tion against the transnational background of philan-thropinism demonstrates that Campe
popularised tenets of this particular educational reform movement. The analy-sis of the interaction between
educative and entertaining elements in Entdeckung clarifies how and to what effect Campe used it to
transmit knowledge: he applied three techniques but the aimed-for control of knowledge trans-mission was
limited.

The Meaning of Israel for the Church. The motives for the presence of the Nederlandse
Hervormde Kerk and the Gereformeerde Kerken in Nederland in Tiberias, 1949-1969
Elizabeth Marteijn, VU University Amsterdam & Protestant Theological University
In 1949, the Nederlandse Hervormde Kerk (NHK, The Dutch Reformed Church) and the Gereformeerde
Kerken in Nederland (GKN, The Reformed Churches in the Netherlands) sent delegates to the Scottish
mission hospital in Tiberias. There are different motives for the Dutch presence in Israel. The crucial motive
for the NHK was the innovative theological idea of the dialogue with Israel of which both the church and the
Jews can learn from each other. The GKN intended to build a relationship of trust with the Jews. The GKN
was especially driven by the emotional impact of the Second World War which got on in the Netherlands.

Lost in Translation? The Subversion of the Right to Prior Consultation in Indigenous Mining
Protests in Guatemala
Anneloes Hoff, University College Roosevelt
Human rights acquire relevance at the local level when they are adapted to the local context and culture.
This adaptation process, which is also referred to as „vernacularization‟, fosters a local rights consciousness,
but also runs the risk of diluting and subverting these international norms. This paper examines the
vernacularization of the right to prior consultation in Sipakapa, Guatemala, where indigenous communities
base their mining protests on this right. The interviewbased case study reveals how the international concept
of prior consultation has become hybridized with the local decision-making mechanism of consulta
comunitaria („community referendum‟). This is problematic, because the implications of the international and
local understanding are fundamentally different.

Proper zwembadwater dankzij aangepaste chloorconcentraties: adsorptie van
'gebonden' chloor
Jessica Aernoudt, Nick Smits and Yentl Pauwel, Ghent University
Chloor is een veelgebruikt desinfectiemiddel in de behandeling van zwembadwater. Als onderdeel van het
desinfectieproces kunnen echter schadelijke bijproducten gevormd worden zoals chloroform en
chlooramines. Een techniek om deze producten te verwijderen is adsorptie op hydro-antraciet en/of actief
kool. Dit werk omvat een vergelijkende studie voor de evaluatie van de performantie van drie soorten actief
kool en één soort hydro-antraciet. Via statische adsorptietesten werden adsorptie-isothermen opgemeten.
Zogenaamde „doorbraakcurven‟, die onder continue omstandigheden opgemeten werden, bevestigden
Centaur als het meest performante adsorbens. Een dynamische simulatie liet toe effecten van parameters
zoals de beginconcentratie op het uiteindelijke adsorptiegedrag te voorspellen.

Hypertension, renal nerves and denervation
Wouter van Amsterdam, Utrecht University
Hypertension, a major cause of cardiovascular disease and death, can possibly be treated with a novel
intervention known as Renal Denervation when standard treatment is unsatisfactory. In this paper we
present a study of the anatomy of the nervous system surrounding the renal artery, which is still largely
unknown. Analyzing 4 human renal arteries, we found a predominance of sympathetic fibers (78.2%),
followed by parasympathetic van afferent fibers (14.9%, 6.8%). Nerves are closer to the lumen in more distal
segments and parasympathetic fibers are closer to the lumen than sympathetic and afferent fibers.

Aminozuurrestrictie in DNA herstel deficiënte muizen
Sangeeta Badloe, Rotterdam University of Applied Sciences
Mensen worden steeds ouder. Echter, het verouderen gaat regelmatig gepaard met vele ongemakken, zoals

The prolongation of length of hospital stay associated with catheter-related bloodstream
infections in critically ill patients in the Netherlands
Jaleesa van Beek,VU University Amsterdam
Catheter-related bloodstream infection is associated with increases in the length of stay (LOS). Up to now,
no information is available about the additional LOS, and the associated costs, caused by CR-BSI in ICU
patients in the Netherlands. To compare LOS and the associated costs between ICU patients with and
without CR-BSI an 11-year (2002-2013) retrospective matched case-control study was conducted with data
from 35 Dutch hospitals. In this study, CR-BSI was statistically significantly associated with additional LOS,
resulting in higher associated costs. These results support the need for ongoing interventions to prevent CRBSI in ICU patients in the Netherlands.

A theoretical model illustrates two effects social capital is hypothesized to have on firm size. First, it
decreases firm size because it diminishes the importance of firms‟ transaction costs saving function. Second,
it raises firm size because it reduces the costs of organizing production inside firms. An estimation using
regional eu data finds evidence of a negative net effect in the water supply/wastemanagement and
construction sectors. This result suggests that the transaction costs effect prevails, which is consistent
with the hypothesis because especially these two sectors are exposed to transaction costs.

Experimental and theoretical study of the influence of conformational restrictions on the
absolute configuration determination of valinol using vibrational circular dichroism
Jonathan Bogaerts, University of Antwerp
Vibrational Circular Dichroism (VCD) is a chirooptical technique that measures the difference between the
absorption of left (LCPL) and right circular polarised light (RCPL) by vibrational transitions in chiral
molecules. In this study, VCD is used to investigate the influence of ring structures on the absolute
configuration (AC) determination of valinol. Three different compounds were synthesised: 4-isopropyl-2,2dimethyl-1,3-oxazolidine, 4-isopropyl-2-methyl-2-oxazoline, 4-isopropyl-1,3-oxazolidin-2-one, all in both the S
and R configurations. It appears that the number of conformers decreases and the VCD-intesity increases
when valinol is in a ring structure. Furthermore, 4-isopropyl-2-methyl-2-oxazoline has the highest similarity
between experiment and calculation.

Peer Feedback in Primary Education: Effects of Feedback Conditions on Handwriting
Improvement
Marjolein van Buuren, Marjon van Keersop and Beitske Verheij, Utrecht University
Feedback can be powerful, but is time-consuming for teachers. Peer feedback might be a solution. This
study reports the effects of teacher feedback, mutual peer feedback, provider and receiver on handwriting
improvement and knowledge. Results from 267 students in grade 3 and 4 of primary school showed no
significant differences in improvement between teacher and peer feedback. However, peer feedback gave
significantly more improvement when peers receive good feed up. Furthermore, peer feedback providers
gained significantly more knowledge than receivers. This indicates that peer feedback can be used in
handwriting education in primary school as an alternative to teacher feedback.

Van zonnebloemolie tot biodiesel: alternatief reactorontwerp
Michiel Coghe, Anke De Clercq, Moreno Geerts, Lennert Rutsaert and Valérie Schepens
Ghent University
Biodieselproductie is een belangrijke schakel in de omschakeling van een aardolie gebaseerde economie
naar een „groene‟ economie. Alternatieve reactoropstellingen voor de productie van biodiesel werden zowel
experimenteel als theoretisch onderzocht en vergeleken. Het gaat steeds om een buisreactor die in mee- of
tegenstroom is opgesteld, in tegenstelling tot de huidige reactoren die van het type mengreactor zijn.
In de onderzochte reactoren wordt biodiesel uit oliën gevormd via een transesterificatiereactie. Eerst werd er

gewerkt met een industrieel toegepaste, homogene,basische katalysator. Nadien werd overgeschakeld naar
een heterogene, zure katalysator welke een potentieel voordeel kan leveren ten opzochte van de huidige
katalysatoren, v.b., een lager energieverbruik.Drie reactormodellen werden opgesteld , d.z., een
homogeen, een twee fasen en een heterogeen propstroom model. Deze modellen lieten toe de verschillende
reactorconfiguraties met elkaar te vergelijken. Er werd ook een simulatie uitgewerkt voor de implementatie
van deze reactoren op industriële schaal.

BAP1 Role in Uveal Melanoma Drug Sensitivity
Valentina Cordò, Leiden University
Uveal Melanoma (UM) is a rare and aggressive type of eye cancer that often evolves into metastasis.
According to gene expression profiling analysis, UMs can be divided into two main groups: Class 1 (low
metastatic risk) and Class 2 (high metastatic risk and bad prognosis). A common feature of most of the
aggressive UMs is loss of one copy of BAP1, a tumor suppressor gene located on chromosome 3. The aim
of this study was to investigate the role of BAP1 in cell sensitivity to chemotherapeutic treatments including
kinase inhibitors, HDAC inhibitor and small molecule drugs reactivating p53.

The Effect of Fatigue on Health Related Quality of Life in Stroke Patients: A Prospective Study
Elise Crompvoets, Tilburg University
Three main consequences of stroke are fatigue, dependency in activities of daily living (ADL), and reduced
health related quality of life (HRQoL). This study hypothesized that fatigue negatively affects HRQoL
in stroke patients, partially mediated by dependency in ADL. This relation was estimated over time. Fatigue
surprisingly decreased dependency in ADL, and fatigue and being dependent in ADL reduced HRQoL.
Dependency in ADL did not change over time, whereas HRQoL decreased. The mediation effect, however,
was not significant. Therefore, the effect of fatigue on HRQoL cannot be stated to be partially mediated by
dependency in ADL.

Why is Bulgaria Lagging Behind the Visegrad Countries?
Ivana Daskalova, Maastricht University
Bulgaria has not democratized as much as the Visegrad countries, which are comparable in many respects,
although basically the same leverage was exerted by the European Union. This contribution attempts to
elucidate this puzzle by examining the geopolitical and economic linkage to the West, the competition
between the political elites after 1989, their interests, and the state capacity. Finally, it is suggested that the
explanation lies in the level of economic linkage, political competition and state capacity. Their level was
much higher in the Visegrad states than in Bulgaria – those elements are therefore necessary for EU
conditionality to succeed.

Het Psychoseksuele Evolutiemodel: over de Paradoxale Machtsvermindering van Vrouwen
als Gevolg van de Anticonceptiepil
Duane de Freitas, University of Amsterdam
De seksuele autonomie geboden door de anticonceptiepil wordt door veel vrouwen als positief ervaren, maar
de langetermijngevolgen zijn mogelijk niet enkel voordelig: het hier gepresenteerde Psychoseksuele
Evolutiemodel beschrijft hoe het lagere zwangerschapsrisico door anticonceptie gezorgd heeft voor fellere
seksuele competitie onder vrouwen, waardoor de voorwaarden waaronder seks plaatsvindt in toenemende
mate in het voordeel zijn van mannen. De seksuele revolutie, gekenmerkt door verbintenisarme seksuele
relaties is dientengevolge ontstaan. Daarnaast gaat de Pil ten koste van de onderhandelingsmacht van
vrouwen met betrekking tot het huwelijk, wat mogelijk de oorzaak is van het afnemende geluksniveau van
vrouwen van de afgelopen vijftig jaar.

The blood lead levels of children in Ulaanbaatar
Elnura Halmambetova, VU University Amsterdam
Air pollution is a big threat to public health of Ulaanbaatar, Mongolia. The blood lead level (BLL) is one of the
major biomarkers for air pollution exposure. The lead exposure results in decreased concentration/attention,
memory loss, poor school performance and decrease of IQ in children. The cross-sectional cohort was
performed on 153 children in Ulaanbaatar. The main outcomes of this study are more than half of the studied
children have a BLL higher than the CDC recommendation; high BLL is correlated to poor school
performance; the estimated IQ of those children is 97 with IQ decline of 4.3 points.

Domain Wall Motion in Materials with Perpendicular Magnetic Anisotropy
Dion Hartmann, Utrecht University & Eindhoven University of Technology
This Thesis reports on our theoretical and experimental study of the motion of magnetic domains in
perpendicular magnetic anisotropy materials. We show that spatial fluctuations of the Dzyaloshinskii-MoriyaInteraction (DMI) give rise to a local in plane magnetic field parallel to the domain wall. Our calculations on
the atomic scale also point out that the sign and magnitude of the DMI strength is strongly related to the
interface structure. This result motivated our experimental study on interface effects which shows that the inplane magnetic field dependence of the domain wall motion is governed by sample growth parameters. We
show that in-plane field effects enter the creep theory in novel ways. Our work leads to new insights
concerning the DMI, in-plane magnetic fields, creep theory and effects of the conditions under which the
studied samples are grown.

Grasping interactions: A novel framework for interactive Hodgkin-Huxley neuron simulation
in hardware
Jonas Hasbach, Maastricht University
Silicon neurons, artificial neurons made from electronics, are currently not applied in the teaching domain
although hardware implementations might be valuable in conveying ideas to the user given that physical
models can be „grasped‟. The author proposes the „extended electronic physical architecture‟ (EEPA), a
novel framework for simulating neurons in hardware that could be applied in the teaching domain and is
capable of simulating non- electronic properties. Furthermore, the technical realization of the EEPA is
demonstrated by implementing a part of the Hodgkin Huxley model in hardware. Model behaviour seems
promising but leaves the implementation in need for improvements.

New forms of terrorism and the role of the Dutch population in the prevention of terrorist
attacks
Tamara Hendriksen and Ganna Hendriksen, HU University of Applied Sciences Utrecht
Terrorism is a long existing, ever changing phenomenon, and will continue to exist in the future. Terrorism
will develop and new forms of terrorism can be formed. For the Netherlands, four forms can be identified as a
threat for the next ten to fifteen years. These forms are: Cyberterrorism, CBRN-terrorism, Lone wolf terrorism
and Radicalism/Jihadism. These forms are subjected to technological developments and digitalization. It
becomes increasingly difficult for civilians to spot signals of these new forms of terrorism. However, there is
willingness from the population to receive more information from the government in order to contribute in the
prevention of terrorist attacks

On the complexity of Maximin Latin hypercube designs
Hao Hu, Tilburg University
Latin hypercube designs (LHDs) are widely used in computer experiments for the approximation and
optimization of black-box functions. However, finding an optimal LHD with good space-filling properties can
be computationally intractable when the number of dimensions and design points increase. No one, to the
best of our knowledge, has so far tried to establish the complexity class of this problem. It is therefore
interesting to show its complexity and make a practical algorithm to find the optimal design. This paper
studies the complexity for this problem and its several variants when the maximin criterion is used to
accomplish spacefilling properties.

Robuuste burgerinitiatieven, voor iedere initiatiefnemer weggelegd? Een onderzoek naar
persoonlijke kenmerken van initiatiefnemers en de robuustheid van hun burgerinitiatieven
Malika Igalla, Erasmus University Rotterdam
Levensvatbare burgerinitiatieven zijn noodzakelijk om sociale problemen duurzaam aan te pakken.
Robuuste initiatieven kunnen intern verantwoordelijkheden delen en zijn extern goed verbonden met diverse
netwerken en kunnen in deze aanpak voorzien. Niet iedereen kan even goed een levensvatbaar
burgerinitiatief beheren. Dit artikel laat zien dat initiatiefnemers die jonger zijn, een eigen huishouden met
kinderen hebben en een beroep uitoefenen dat gerelateerd is aan de publieke sector dit beter kunnen. Door
dit beroep worden veel boundary spanning activiteiten ondernomen. De mobilisatie van bronnen, zoals
financiën en overheidssteun, neemt toe, als ook de robuustheid. Loert hier de ongelijkheid van
zelforganisatie?

Structural studies of EDDS lyase
Marijke Jansma, University of Groningen
EDTA is a versatile chelating agent which can bind a wide range of metals. Unfortunately, its wide-spread
application causes significant soil pollution, due to the low biodegradability of this chemical. EDDS, a
structural isomer of EDTA, is an environmental-friendly alternative because it is biodegradable. EDDS can be
synthesized enzymatically with EDDS lyase. This enzyme can form EDDS from fumarate and
ethylenediamine. In this project, the 3D structure of EDDS lyase with different substrates bound in its active
site was studied using X-ray crystallography in order to gain more insight in the enzymatic reaction
mechanism.

Income inequality, redistribution and democracy
Linda de Jongh, Maastricht University
Income inequality can lead to reduced growth, political conflicts and other social ills. This paper looks at
whether the democratization process has an influence on income inequality. A panel data set of 56 countries
between 1990 and 2006 with the polity score and gini index as proxies for democratization and income
inequality, respectively, is used. It is found that democratization leads to more inequality until a polity score
of 8 is reached. However, for (post)communist countries, there is first an increase in inequality where after it
decreases. Additionally, it seems that mainly the independence of politicians drives these results.

The influence of creative self-efficacy on creative performance
Bianca Koeman, Tess van der Kolk and Sander Brockhus, Delft University of Technology
Creativity can be expressed within different forms of representations such as writing, painting or reasoning.
This paper argues the influence of creative self-efficacy on creative performance, which was measured by
conducting a questionnaire and an assignment on creative performance. The results were assessed on three
categories of creativity: fluency, flexibility and originality. A statistical comparison between these categories
and creative self-efficacy resulted in a correlation which induces that creativity can be increased by
enhancing creative self-efficacy.

Pathway to Parental Alienation
Heleen Koppejan-Luitze, Open University of the Netherlands
The behavior of eight residential parents whose children struggle with the visitation-agreements after a
divorce, has been explored through in-depth interviews. The interviews indicate that the overt behavior of
residential parents may be guided by their feelings towards non-residential parents. Specific experiences in
their past are seen to result in a typical dynamic routing directed at influencing the child‟s loyalty against the
other parent. This study also indicates that the parent‟s feelings may become mirrored by their children, who
may consequently internalize them as if they were their own. The outcome of these processes can be a
shifting loyalty of the child, which opens up the way to parental alienation.

Metabolic acceleration within gastropods: An analysis of deviating growth patterns from the
Dynamic Energy Budget theory within several gastropod species
Lars Kramer, Joris Koene and Sebastiaan Kooijman, VU University Amsterdam
Since the last decade, Dynamic Energy Budget models have done a great job at creating a better
understanding of organism energy and nutrient use, while maintaining and expanding a database on these
organisms, which currently counts over 300 species. However, in order to incorporate and understand more
deviating growth patterns, this database will require a wider range of employed growth strategies. In my
research, I have investigated the presence of metabolic acceleration within four freshwater snails divided
over two families and four genera. The results indicate that the species Lymnaea stagnalis, Stagnicola
palustris, Planorbis planorbis and Biomphalaria glabrata all show signs of a metabolic acceleration. Further
analysis also indicated that the degree of metabolic acceleration was influenced by the presence of
conspecifics for Lymnaea stagnalis, whereas the other three species exhibited no direct connection between
metabolic acceleration and the presence of conspecifics. Moreover, the relationship between the size of the
shells and the weight of the snails seems to indicate that the presence of metabolic acceleration is more
closely linked to the morphology of the snails or the gradual growth of bacteria in the colon. These results
highlight the necessity of detailed growth data on lengths, weights and reproduction, in addition to theoretical
models -that are essential for interpretation and further hypothesizing- in order to accurately describe any
model organisms.

De Relatie tussen Mindfulness en Stress: de modererende Rol van Zelfwaardering
Brenda Lelie, Open University of the Netherlands
In deze studie wordt onderzocht of de negatieve relatie tussen mindfulness en stress beïnvloed wordt door
iemands zelfwaardering. In een cross-sectioneel vragenlijstonderzoek zijn mindfulness, stress en
zelfwaardering gemeten. Uit de resultaten blijkt dat mindfulness en stress negatief met elkaar samenhangen.
Voor mensen met een lage zelfwaardering is deze negatieve samenhang sterker dan voor mensen met een
hoge zelfwaardering. Opvallend is dat dit moderatiemodel wel geldt bij de mindfulnesssubschaal Acceptatie
en niet bij de subschaal Aanwezigheid. Dit zou een aanwijzing kunnen zijn voor het inzetten van
mindfulnesstraining specifiek voor mensen met een lage zelfwaardering waarbij dan vooral
acceptatievaardigheden getraind kunnen worden.

E-cigarettes: Legislating the conflicting interests among consumers, tobacco companies, tax
authorities and public health
Lisaima Luijten and Tatiana Degtyareva, Utrecht University
Originated in China, electronic cigarettes found their way to the European and American markets in 2006
and 2007, respectively. In May 2014, the European Union effectuated a new Tobacco Product Directive that
concerns regulation of tobacco related products including e-cigarettes. This raised the question why the
legislative authorities in the EU and US want to tax and regulate these non-tobacco containing products as a
tobacco related product. Analysis of the tobacco market, its involved parties and the stakes involved, lead to
the conclusion that the concerned authorities are more inclined towards protecting private interests rather
than public health.

Retractions in Psychological Research
Alexej Michire, Maastricht University
The main purpose of the current study was to examine the belief perseverance effect in a sample of
academic psychologists. It was assumed that the presentation of misinformation would produce belief
perseverance that would perish after a powerful debriefing manipulation. To test this, academic
psychologists were asked to read a retracted paper and fill in two identical belief measurement scales about
the content of the paper at two different times. Out of three different conditions the debriefing manipulation
was presented in the Debriefing condition between the two measurements. As expected, belief perseverance
perished in the second measurement. These findings suggest that retractions are effective in psychological
research for academic psychologists.

Het Evalueren van Specifieke Verwachtingen: Hoe goed is onze Intuïtie over Power?
Annemarie Prins, Utrecht University
Veel onderzoekers hebben specifieke verwachtingen over de uitkomst van hun onderzoek. Deze
verwachtingen worden vaak indirect geëvalueerd met Nul Hypothese Toetsing en p-waarden, waarbij er
meerdere testen uitgevoerd moeten worden om steun te krijgen voor de verwachting. Waar onderzoekers
zich wellicht niet bewust van zijn, is dat de power om ondersteuning te vinden voor deze specifieke
verwachting snel afneemt, naarmate meerdere testen uitgevoerd worden. In deze studie is onderzocht in
hoeverre onderzoekers zich bewust zijn van deze deflatie van power. Er blijkt een grote discrepantie te
bestaan tussen de werkelijke power voor de bevestiging van een specifieke verwachting en de
inschatting van sociale wetenschappers.

Comparison of the CD8+ T cell response after yellow fever vaccination of
immunocompromised and healthy individuals
Melissa van der Sluijs, VU University Amsterdam
Yellow fever is a mosquito transmitted virus. Since no treatment exists, vaccination is the only way of
prevention. The vaccine is considered to be safe, but can provoke severe side effects in
immunocompromised patients. This study aims to compare these patients to healthy individuals to gain more
information about this immune response and possibly formulate new vaccination guidelines. Blood samples
were taken and participants filled in a questionnaire about adverse events after vaccination. PBMC‟s were
isolated. Tetramer LLWNGPMAV was used to display CD8+ T cells by FACs analysis in HLA-A2 positive
participants. We found no significant differences between these groups.

Local agro-management and landscape effects on pollination in agricultural fields
Eva Thuijsman, Wageningen University
This review evaluates 13 recent (2007-2013) studies on pollination in organic and conventional fields, at a
local and a landscape scale. Pollinator abundance and diversity were mainly associated with flowering plant
diversity and cover, at a field and at a landscape scale. Organic management enhanced pollinator
abundance and species richness compared to conventional management in half of the cases, mainly in
pollinator-independent crops. Remarkably, pesticide use had no effect on pollinators (when measured
separately). Landscape heterogeneity with nearby natural habitats supplemented the effects of local
management, rather than overruled them.

MK-801 as a deficit model for schizophrenia and the possible counteracting effects of
risperidone and donepezil
Thecla van Wageningen, Maastricht University
This research focused on the possibility to use the N-methyl D-aspartate (NMDA) receptor hypofunction
theory of schizophrenia to find new ways to treat cognitive deficits seen in schizophrenia. The Object
Location Task (OLT) was used to verify if the NMDA-antagonist MK-801 can induce cognitive deficits in
(spatial) memory in mice. Subsequently the OLT was again used to test if the drugs donepezil and
risperidone could counteract the cognitive deficits induced by MK-801. In this study it was confirmed that the
NMDA antagonist MK-801 in doses higher than 0.1 mg/kg induces cognitive deficits. Surprisingly, donepezil
showed a strong trend in counteracting the MK-801induced deficit.
