Greetings from the chair...

Greetings! Thanks for reading our 3rd annual department newsletter. As you can see, the

2011-12 academic year was very eventful! The word for the coming year is change . As students return to campus, they will notice that the third floor atrium area has been updated to reflect our emphasis on cooperative learning. The corner that typically holds the prized slide rule will now have walls that you can write on with dry erase markers. Moveable tables and chairs will allow students to work together in different configurations.

For additional problem-solving fun, students can also write on the tables! Hopefully we will see more of our majors working and learning in this new space.

Of course, it is the people who really make the department what it is, and we have some changes to announce in this area as well. This past spring saw the

retirement of Linda Barbu, who has been in the department for 25 years. We will miss the bright smile and the generous spirit that has graced the math center during her career at Wooster. Ronda Kirsch, who taught for us last year, will join the staff permanently as an instructor and also as the new director of the math center. Please stop by and say hello to Ronda. This spring we said goodbye to Professsor Jim

Daehn, who has taught Computer Science for the past two years. Jim is now in Missouri where his wife has a new job, so we wish them the best. Professor Samer

Khasawneh, who just completed his Ph.D. from Kent

State University, will fill in as a visiting faculty member in Computer Science this coming year, so we welcome him.

We also have two new faculty joining us in

Mathematics this year—Matt Moynihan and Bob

Wooster. Yes, you read his name correctly. We are looking forward to several years of playing up Bob’s last name whenever possible. Professor John Ramsay is beginning a three-year position as the Associate Dean for

Experiential Learning. He will continue to teach one course each semester and advise I.S. projects, but he will be spending a bit more time working to ensure that

Wooster students continue to have exciting opportunities for learning outside the classroom. The year ahea be an exciting adventure for us!

Elements of understanding: mathematics, literature, and Nicolas Bourbaki

This Independent Study is a historical analysis of a trend of twentieth century ideologies, starting with Nicolas Bourbaki, that sought to apply strict methods of organization founded in the logic of Set Theory. I first study the history and the works of Nicolas Bourbaki before drawing connections to other topics. Nicolas Bourbaki is a pseudonym for a group of French mathematicians who tried to reorganize the elements of mathematics in the disorder of the early twentieth century. When mathematicians and policy makers in America and abroad felt that mathematics education was inadequate, many turned to Bourbaki’s methods. To better understand how methods have evolved, I examine several expositions of Set Theory.

Bourbaki’s efforts influenced not only mathematicians and scientists, but also academics working in the humanities. French literary group Ouvroir de

Littérature Potentielle (OuLiPo) worked with elements of writing to explore potential modes of creating literature. By describing the various means of employing elements in separate cases, I consider different methods to understand how certain constraints may be better suited for distinctive goals.

Entrapment and determination of lipase embedded in swellable organosilica, modeling particle aggregation and aging of colloidal sol-gels

The immobilization of enzymes has been extensively cited for use as robust biocatalyst in industrial processes. Immobilization is typically directed towards reinforcing enzyme stability and extending the range of operating conditions over which enzymes remain catalytically active. Sol-gel encapsulation provides a convenient route to immobilize enzymes and other biologicals as a result of the low temperature chemistries required and the fine control over the fabrication of the material. However, conventional protocols for encapsulation involve pre-mixing enzymes in solutions that often lead to denaturation. Swellable organosilica may provide an alternate route to embedding enzymes in inorganic scaffolds. In this work lipase was trapped within swellable organosilica post gel synthesis. Lipase was found to be active within the organosilica as determined by enzyme hydrolysis of 4-nitrophenyl butyrate. Organosilica that swell depend critically on morphologies of the aggregated structures that make up the gel network and pore collapse that occurs during aging of the colloidal gel. A model for particle aggregation and aging of colloidal gels was developed towards predicting and understanding the swellable properties of organosilicas that exhibit them. The model adapts and extends the DLCA model, used to describe the aggregation processes in colloidal gels, to account for gel shrinkage of the aged gel. Model validation against physical quantities suggested that flexibilities in the aggregating structures and rearrangements of the aggregates during aging of the gel are important to the display of swellable properties.

A substantial amount of research has been done on finding models that are used for predicting sports outcomes. More research has been conducted involving other sports, including NCAA basketball, than with the NBA. The focus of my study was to see how accurate artificial neural networks would be in predicting the outcome of NBA games and the margin at which the team would win by. The results from artificial neural networks were then compared to linear models to see which model would be more accurate. Data from 2008-09 and 2009-10 seasons were used in the models and tested on the 2010-11 season. Another model used was choosing the home team to win and see how accurate this pick would be. Seven different models are compared to find which statistics best fit in predicting NBA outcomes.

Iteration Digraphs

An iteration digraph, G(n), generated by the function f(x) (mod n) is a digraph on the set of vertices V={0,1,.. n–

1} with the directed edge set E={(v, f(v)), for all v in V}.

Focusing specifically on the function f(x) =

10x (mod n), we consider the structure of these graphs as it relates to the factors of n. The levels, cycle lengths, and number of cycles are determined for any integer relatively prime to 10.

Isomorphic subgraphs arising from multiples of 3 and 9, and tree structures specific to powers of 2 and 5 are also described.

An Exploration of Hyperbolic Geometry/Mathematics and Studio Art

The mathematical component of my Independent Study researches the development of hyperbolic geometry and discusses three specific hyperbolic models: the Poincare disk, the upper half-plane and the Beltrami-Klein model. Focusing more on the Poincare disk because of its simplicity, the axiomatic system of hyperbolic geometry is explained. The hyperbolic axiomatic system includes the postulates, definitions, and theorems from absolute geometry, as well as the altered fifth postulate and dependent theorems. The fifth postulate is what separates Euclidean geometry from hyperbolic geometry. When given a line and a point not on the line, there is only one parallel line to the given line through the point in Euclidean geometry, whereas in hyperbolic geometry there are at least two parallels.

The altered hyperbolic fifth postulate affects many theorems and this thesis examines those hyperbolic theorems through three models. Unique to each model is the formula for measuring distance between two points. The distance formula is crucial to understand in order for a model to be consistent with hyperbolic geometry. The Studio Art component of my

Independent Study explores hyperbolic concepts through multiple color block prints. I created several relief multiple color block prints that focused on differences between Euclidean versus hyperbolic theorems. My relief prints retain an immediacy of the action of the carved mark and patterns. The intaglio multiple color prints I created retained more of a tonal effect through the various etching techniques employed. My

Multi-plate copper intaglio piece 1 intaglio prints were inspired by specific concepts in hyperbolic models. Both the relief and intaglio prints rely heavily on the relationship between plates for an effective abstract piece. This includes the image and color choice to best represent the concept from which it was inspired.

Multiple block printing allowed me to create a threedimensional illusion of hyperbolic space in comparison to two-dimensional mathematical diagrams. There is a technical side and an abstract side to my Independent

Study on hyperbolic geometry. The collection of pieces I produced can be understood on multiple levels dependent on the viewer's mathematical knowledge, which is similar to how hyperbolic geometry is understood in many different models. Researching hyperbolic geometry from a mathematical and artistic viewpoint helped round out both components of my Independent Study.

Two-person Zero-sum Game Theory: Batter vs Pitcher

This study explores two-person zero-sum game theory. The paper begins by giving a brief history of how game theory was founded. Next the basic definitions of game theory problems are given to help understand the structure of a game. These definitions allow for a section about two-person zero-sum games to be written. In this section lies a proof of the minimax theorem, which is one of the main theorems in game theory. The next chapter shows a few of the different ways to solve two-person game-theory problems.

Knowing what these problems are and how to solve them helps create a real life example. The problem in this paper analyzes a game between the pitcher and a batter in a baseball game. Taking data from the 2011 major league baseball season, a game theory problem was created and solved. The solution was then analyzed to help understand optimal pitch selection.

Topical Web Crawlers

A Web crawler is an automated program that recursively indexes Web pages found by following hyper-links from the parsing of other pages indexed during its crawl. With the World Wide Web’s exponential growth rate, however, standard Web crawlers no longer suffice when the depth of a specific topic is required. A topical, or focussed Web crawler, is one that traverses the Web looking only for sites that are related to some pre-defined topic, while avoiding those not related. This thesis explores and critically analyzes various topical crawling algorithms, details the methods they utilize, introduces our own topical Web crawler, called WooSpider, and presents the results of experiments that measure the effectiveness of various versions of

WooSpider.

Computational profiling and identification of the 3’ untranslated region within Paramecium tetraurela

The 3’ untranslated region of mRNA is of particular interest for determining localization within a cell, and may play a role in evolution of genes. However, the 3’ region is not easy to determine for all mRNA within a cell. A profile of the 3’ untranslated region within Paramecium tetraurelia is explored. This profile can be used to predict the cleavage site as well through the use of a modified Hidden Markov Model. Also, using conserved domains known to bind to mRNA, different mRNA binding proteins were identified in an attempt to identify those that bind to control localization. Concurrently, a method to experimentally determine the 3’ untranslated region was developed as a method to confirm results from the probabilistic model. This was accomplished through first creating cDNA and using a primer 50-200 nt upstream from the stop codon and a poly dT primer to amplify the 3’ untranslated region for sequencing. With the methodology, the predictions can be verified.

Monte Carlo Simulations of the Clumpy

Torus in Active Galactic Nuclei

It has been observed that approximately 10% to

30% of AGNs show no X-ray absorption, whereas the optical spectrum suggests significant obscuration. One possible explanation is that the obscuring medium consists of dense clumps. In the model, using Monte Carlo simulations, I conduct a study to check whether the clumpiness of the torus is a possible reason for the mismatch in optical and X-ray spectrums. For a variety of torus configurations I have found that there is no mismatch in the number of the clumps intersected between the lines of sight originating

in the X-ray and optical regions. If time variability is assumed I found that, due to clumpiness, it is not possible to change the spectrum of AGN galaxy from absorbed to unabsorbed, but clumps could be responsible for more mild variations in the spectra. If the X-ray and optical spectra are not simultaneously observed there exists some level of disagreement on the degree of obscuration.

Similarly Intriguing and Perspectively Odd: Fractal and

Projective Geometry Explored in M.C. Escher’s Art

M.C. Escher was an artist during the early to mid 1900's who primarily focused on woodcuts and lithographs that had a small contribution to the world in mathematics; his most famous being the lithograph Print Gallery in

1956. However, the focus of this thesis is on his works that exhibit characteristics found in the properties of self-similar sets of fractal geometry and properties of projective geometry. The works include two woodcuts that exhibit self-similar sets, and three lithographs, all of which use projective geometry to create optical illusions. Mathematically speaking, in fractal geometry, Hausdorff dimension is discussed using multiple examples that are also self-similar sets. Following, projective geometry is discussed providing the axioms and function of

Experimental and theoretical investigation of the dimerization of oxalic acid, a potential reaction within secondary organic aerosols

Atmospheric aerosols play a major part in climate change by affecting air quality and the balance of radiation impacting our earth. Oxalic acid is a major component of secondary organic aerosols and is hypothesized to produce dimers within an aerosol’s composition, thus increasing the concentration of organic carbons in the air. This study investigates the dimerization of oxalic acid in an “organic material simulator”, dimethyl sulfoxide (DMSO). Computational chemistry was used to determine theoretical vibrational frequencies and thermodynamic properties.

Theoretically, it was found that the dimerization of oxalic acid is a nonspontaneous reaction with an equilibrium constant that lies to the reactants, or monomeric units of oxalic acid. Although while following Le Chatelier’s

Principal, as the concentration of the oxalic acid increases the reaction is driven to the products. Fourier-transform infrared spectroscopy (FT-IR) was used to obtain experimental vibrational frequencies. The experimental data supported our hypothesis that as the concentration increased more major peaks were associated with theoretical dimer vibrations. Following, the experimental IR data was used in a model known as band target entropy minimization (BTEM) to reconstruct the pure components of the oxalic acid/

DMSO solution. The model was successful in reconstructing the solvent,

DMSO and some of the major components of the IR spectrum of oxalic acid.

However, the optimization was very unstable while trying to find a local minimum. A sensitivity analysis is needed to analyze the sensitivity of the parameters with respect to the model. From this study it can be concluded that dimerization may occur within an aerosol’s composition but more investigations with other solvent environments are needed.

Making Money, Making Sense: An analysis of the Modern

Portfolio Theory and the performance of alternative risk measures

Investing in the securities market exposes investors to both market risk and returns. Measurement of expected returns is relatively easy since there is a generally accepted method of calculation. However, there is no consensus on the best way of quantifying security risk. The classical method is to use variance; over time, a number of alternative methods have been developed.

This paper contributes to literature by examining the explanatory power of the nine most cited alternative risk measures in a comprehensive model. Empirical analysis is performed using regression analysis. The main result of the paper is the observation of a direct relationship between risk and returns, as predicted by theory. The risk measures that display consistent,

Plane and Ellipsoids representing return and risk levels respectively significant explanatory power are Sharpe’s β , kurtosis, value at risk and market capitalization. Results of the Kolmogorov-Smirnov test for normality confirm that 82% of the security returns did not come from a normal distribution. The paper also develops the critical line algorithm used for calculating optimal portfolios leading to the derivation of the efficient frontier.

Using mathematical models to evaluate NFL field goal kicking

NFL field goal kickers are often criticized for failing to make crucial field goals, but the best kickers are rarely recognized for being such. In an era of growing statistical research, field goal kicking is not widely studied to the same extent as other statistics. This project uses artificial neural networks to create difficulty ratings for NFL field goals.

Using these ratings, kickers are evaluated based on a points added system as well as numerous other metrics, and there are clear distinctions between most kickers. Despite popular opinion that field goal kickers are largely replaceable, this study shows just how different kickers are and how to recognize which ones are the most successful.

Procedurally generating everything

This paper investigates using Perlin Noise in a three-dimensional environment. Perlin Noise has previously been used to simulate clouds, marble, wood, and other natural phenomena as well as to model virtual landscapes. The simulation created for the I.S. procedurally generates both static and animated textures and models virtual landscapes to create a virtual world. In order to keep up with the rapidly advancing graphics industry, the OpenGL API is utilized to generate the textures in real-time and to display the final product.

This work investigates the coding theory, cryptology and the role of cryptology in the development of American intelligence gathering. Coding theory and cryptology are both mathematical studies that change a set of data into another form, but each has a different purpose. Codes are used to correct transmission errors, while ciphers are used to secure data from unwanted readers. The rise of

American cryptology was the driving force behind the rise of American intelligence through the twentieth century. America had little intelligence gathering before it started its period of expansion, creating an intelligence void that needed filled.

The rise of cryptologic intelligence helped Americans fill that void.

Quantum Gravity: Exploring the Causal Dynamical

Triangulation Approach

Quantum Gravity is an attempt to unify the current understanding of the microworld (governed by quantum mechanics) with the current understanding of the macroworld (governed by general relativity). This thesis provides a brief overview of the problem of quantum gravity, including conceptual as well as technical overviews of general relativity and quantum mechanics. It explores a conservative approach to quantizing gravity known as Causal Dynamical Triangulation (CDT). CDT constructs spacetime from triangular-like building blocks known as simplexes.

Combining quantum mechanics and general relativity by a sum-overgeometries, CDT demonstrates that microcausality implies classical global spacetime. This thesis focuses on a bare 1+1 dimensional universe. It converts the Einstein-Hilbert action of general relativity (from which one can recover the Einstein Field Equations using the principle of least action) from continuous to discrete form using the Gauss-Bonnet theorem, which is rigorously developed. This thesis proves a version of the theorem on two dimensional Euclidean polyhedra and sketches a proof on Pseudo-

Riemannian spaces. Finally, it describes the design, construction, and operation of a computer simulation of a bare 1+1 dimensional CDT universe.

It uses the simulation to find a critical value for the cosmological constant and computes the corresponding fluctuations in the spatial size of the universe, which it compares with analytical results.

The Wooster Problem: a staff scheduling problem with an application to student activities

The comprehensive topic of research for this project is staff scheduling. The goal of the thesis is to develop a unique staff scheduling linear programming model for summer conference student staff scheduling at Wooster. The model design is based on the needs and priorities of Wooster’s summer conference staff scheduling. The College of Wooster Student Activities Office hires a small team of students every summer to staff the Wooster Summer

Conferences. These “conferences” include athletics camps as well as more traditional conference activities. Modeling work in this thesis presents a

“proof of concept.” That is, there has been enough preliminary research and work done to verify this as a way to model staff preferences. The models solved focused on the staff level ability to meet demand and maximizing staff preferences. The Wooster model formulated aims to maximize student preferences given a set number of staff. The solutions to the model yield a level of at which staff preferences are satisfied for a particular staff level.

The marginal increase in the normalized solution values as we move from 6 to 7 up to 8 staff members demonstrates the model moves closer to an ideal preference level. The results will then not necessarily be the optimal solution found from each model, but rather an

Rounding the optimal solution can cause infeasibility extrapolation of information from those solutions that demonstrates how much they are able to increase students preferences marginally. With set objectives in mind research and model design began.

Model looking at the expected number of shots to hole out on a golf course

This research is modeling the expected number of shots to hole out from anywhere on the golf course. This research could potentially be used to improve one’s golf game or see where their game needs work. The author has received permission from the PGA Tour to use ShotLink data and has used this data to help compute the expected number of shot values. While using the model made based on the expected number of shots to hole out, the author has also looked at two very distinct

Driving scenario used in this research applications of this model. The first involves a driving scenario that takes into account a risk/reward situation that puts an emphasis on choosing to play aggressive or playing conservative.

Finally, the second application looks at an approach shot scenario in which multiple golfers of different skill levels are hitting into a green. This scenario then helps determine which target each player should use to get the best possible result based on the expected number of shots.

Computer generated architecture through nature: using swarm intelligence and evolutionary computing to generate

3D models

This paper examines the nature inspired machine intelligence methods of swarm intelligence and evolutionary computing. Swarm intelligence algorithms utilize stigmergy, indirect communication through environmental changes, to create emergent, complex, cooperative behavior amongst primitive, “dumb” actors. Some examples of such algorithms are Ant

Colony Optimization, based on ant foraging behavior and the use of trail pheromones, Firefly Algorithm, based on the bioluminescence fireflies use to attract other fireflies and the concept of light dispersal with distance, and Wasp

Nest Building Algorithms, based on the cooperative nest building of many wasp species. Contrary to popular belief, when building nests experimental evidence has indicated that it is not due to an internal blueprint but rather reactions to environmental states that drives the actions of each wasp - in other words,

Architectural form of a terraced tower generated in the simulation using a hand-crafted rule set wasps employ stigmergy to build their nests. The nest building algorithm utilizes a population of agents moving about in a 3-dimensional (3D) environment and who, given a set of “building rules”, place building blocks in the environment in order to construct an architectural form. Evolutionary computing employs methods from Darwinian evolution and genetic theory to produce a solution to a problem through the creation of successive populations of possible candidate solutions. The problem controls the evolutionary process through a fitness function that evaluates the quality candidates' solutions and drives selection and reproduction opportunities.

This paper examines the implementation and applications of these natureinspired swarm intelligence algorithms in conjunction with evolutionary computing and the potential to implement an evolutionary wasp nest building algorithm that evolves the ability to generate a desired architectural form.

Mining the Linux source code, an examination of data mining

This project aims to examine data mining. It aims to gather data from the

Linux source code and mine to the collected data using three data mining algorithms, Clustering, Association Rules, and Decision Trees. Each algorithm will be implemented in a piece of code created specifically for this project. Library research into the three specified algorithms will be a necessity as well as the encoding of the programs themselves. A potential problem that this project may hold is that there may be no discernible patterns within the Linux source, and data mining it would produce no conclusive results.

Parity-based Measurement and Control of the

Spatial Wave Function of Photons

The experiment involved parity based measurement and control of the spatial wave functions of photons. To achieve this, the theory was developed for a 1-dimensional parity based interferometer. This interferometer was capable of taking a laser beam input that consisted of a specific solution set of Hermite-Gaussian modes and span of this solution set as well. The resulting theory was then modeled for several types of input beams and simulated for several special cases. The mathematical relationships governing the interferometer were exploited and simplified to establish a general matrix with complex entries that would model the output of any beam input to the interferometer. It was then proven that this governing matrix was unitary. The modeled interferometer was then built and the results of multiple input beams were analyzed through the theory and simulations that were built based off of the general interferometer matrix. By analyzing certain properties of beams that were input to the interferometer, one could in effect determine certain properties of the photons that could not otherwise be measure without losing the usefulness of the photon. By tweaking parameters within the interferometer one could also change the output of the interferometer without changing the input beam. This is changing the spatial wave function of the photon. In this respect the experiment achieved its purpose although much can still be done to optimize the interferometer set up and effectively learn more about the input beams.

By changing the parameters in the spherical coordinates

θ and φ one can create any rst order mode. All first order modes can be represented as some point on the sphere, thus this sphere visually represents the entire vector space described in the experiment.

Is Efficiency Optional? A study regarding the binomial options pricing model, transactions costs, and the implications of options on market efficiency

Ever since the concept of market efficiency was defined, individuals have been trying to find ways to measure, test, and show different levels of efficiency in markets. Efficient markets show a reflection in value from information. This study concerns itself with the market for securities.

Specifically, it is concerned with the question, ‘What effect does the options market have on the efficiency of the underlying security?’ Given the above question, this study takes the position that the options market has a narrowing effect on the transactions cost of a security, which stands as a measure of market efficiency. As such, it is noted that the existence of the option allows dealers to better value the underlying security, and thus the market is more efficient. This study derives an option pricing model, follows it with a theoretical section, and then outlines the expected negative relationship between the options market and the efficiency of a market, due to the options market being an additional piece of relevant information regarding the security’s future performance. It then offers an empirical test of this hypothesis, the results of which do not support this hypothesis.

Just for fun...can you solve this problem from our high school math contest team test? (almost every team got whole or partial credit on this one!)

The Chinese game of nim is played as follows: There are several piles of matches, each containing an arbitrary number of matches at the start of the game. To make a move, a player who removes the last match wins the game.

A winning position is an arrangement of matches in piles such that if a player can move to this position, then

(no matter what the second player does) the first player can continue to play in a way that will win the game.

Show that the position in nim where there are two piles, each with two matches, is a winning position for the second player.

MODELING TENSION IN WOUND POLYESTER FILM

This project applied winding concepts such as radial pressure, yield point, Young’s modulus, friction, and Hakiel’s simple winding model to predict the occurrence of telescoping and dimpling, two common winding defects at Kent

Displays©, in polyethylene terephthalate

(PET) rolls, which are used to make Boogie

Boards. Hakiel’s simple winding model was closely examined and implemented in

MATLAB® during the early stages of this project. After validating the predicted pressure measurements from Hakiel’s model with measurements taken at Kent Displays©, telescoping and dimpling were then examined. In addition to discovering the location and frequency of telescoping and dimpling in PET rolls, common winding variables, such as taper percent; roll length; initial tension; radial, tangential, and core modulus were closely studied. Lastly, a list was compiled on how altering winding variables affects radial pressure in a wound roll.

ANALYSIS OF STUDENT RETENTION AT THE COLLEGE OF WOOSTER

The purpose of this project was to analyze data in order to better understand student retention, specifically, students who left The College of Wooster. How can we utilize admissions data to predict the likelihood that a student will leave the College by the end of his or her first year?

Using additional information attained during a student’s first semester, how well can we predict the likelihood that a student will leave the College by the end of his or her first year? Which students are most at risk of not graduating in four years? We attempted to answer those three questions using several methods, such as probit regressions and artificial neural networks.

FINDING REGULATORY MOTIFS IN THE SOLANUM LYCOPERSICUM GENES

Transcription factor binding sites (motifs) are small portions of proteins that are homologous to regions in other proteins. To date, such motifs of genes in the Solanum Lycopersicum (tomato) have not been discovered. This research seeks to find potential transcription factor binding sites (promoters or motifs) of genes in the

Solanum Lycopersicum plant with the hope that this will give insight into those genes that are similarly regulated. This research was performed at Ohio Agricultural Research and

Development Center.

This project is a continuation of past research. During our time this summer, our team created a digital catalogue of over 50 Klein links. In addition, we investigated connections between the invariants of torus links and Klein links with the goal of further understanding the effects of our construction. Through this research, we were able to discover results that related the crossing number of torus links to Klein links and

Klein links to Klein links. After developing these ideas further, we created a paper that involved these findings and hope to publish these results in the future. We will be presenting a portion of our findings at the 2012 UnKnot Conference at Denison University.

MOLECULAR IMAGING USING KINECT

The goal of this project is to extend the work of the Molecular Playground for use in an educational environment. The Molecular Playground is a hardware-software installation that allows the user to rotate 3-D chemical molecules.

This is done by capturing hand positions detected by the Kinect camera and sending these positions to a 3-D modeler. Our extensions also support 3-

D rotations and add x-y translations, molecule selection and partial molecule rotation. This allows the chemistry instructor to interact more naturally with the model and without direct contact with the hardware.

MODELING EMPLOYEE FLIGHT RISK FOR

AMERICAN INTERNATIONAL GROUP, INC.

The goal of this project was to develop a model that will allow AIG to predict, based on key variables, an employee's likelihood of leaving the company. The work toward this goal resulted in a variety of deliverables provided for AIG. First, the

AMRE team cleaned and recoded several databases of uncombed data which were then merged into one master data file to be used for statistical analysis. In addition to this new "statistics-friendly" database, a data cleaning program was created in Microsoft Excel. This program gives AIG a tool that will speed the data cleaning process as they add new data for analysis.

Third, some static snapshot analysis was performed on the new master data file. Key variables in flight risk prediction were determined through literature research and statistical tests. A few noteworthy findings were shared with AIG with recommendation to pursue this analysis further as more data becomes available. Finally, a mathematical model for predicting employee flight risk was created. The model is based on Probit analysis and assigns a flight risk probability to each employee based on key profile variables. AIG was provided a final set of recommendations for ways to improve their systems and data gathering techniques as they continue with their predictive analytics efforts.

ASSESSMENT FRAMEWORK FOR EXPERIENTIAL LEARNING AT

THE COLLEGE OF WOOSTER

This project is a continuation of the 2011 AMRE project: College of Wooster Assessment. We conducted research on experiential learning (EL) in general and EL opportunities at Wooster in particular. Our goals were: 1) create clear guidelines for each tier, along which EL programs can be classified and 2) develop assessment tools for EL programs which reflect the unique nature of each program. We investigated and developed a model for EL, which is the foundation for our threetiered classification framework. In the assessment component, we created assessment tools and assessment processes pertinent to two different groups of EL programs. These tools should help the College make more informed and effective decisions regarding the allocation of support to and investment in EL programs. We also outlined the EL process that students might have to undertake in order to participate in EL experiences.
