Quantum Groups And Knot Invariants, Greg A. Hamilton

Honors Theses

Knot theory arguably holds claim to the title of the mathematical discipline with the most unusually diverse applications. A knot can be defined topologically as an embedding of S1 in R3. Naturally, two knots are topologically equivalent if one cannot be smoothly deformed into the other. The question of whether two knots are equivalent is highly non-trivial, and so the question of knot invariants used to distinguish knots has occupied knot theorists for over a century. Knot theory has found application in statistical mechanics [1], symbolic logic and set theory [2], quantum fi theory [3], quantum computing [4], etc. …

As Good As Niu: Food Sovereignty In Samoa, Emily Gove

Honors Theses

Samoa’s history as an island nation, with its cultural heritage of migratory peoples, followed by settler colonialism and missionaries, has resulted in its uniquely amalgamated food system. Cuisine varies from traditional crops and recipes to imported canned goods, although dependence on the latter has led to wide-ranging health problems. A way to confront these problems is through reclaiming local cuisine, renewing its popularity and promoting the concept of food sovereignty. Through fieldwork based on surveys, interviews, and participant observation in Apia, complemented with a study of activist Robert Oliver’s new cookbooks on Pacific cuisine, this project examines current themes …

Le Bénévolat Introspectif: Une Réflexion Sur Médecins Sans Frontières, Tony Gonçalves Da Lomba

Honors Theses

Cet essai explore la théorie de faire du bénévolat tout en explorant aussi la mission de M.S.F. et son infrastructure. En même temps, c’est une occasion de juger que M.S.F. n’est pas une exagération du complexe du sauveur blanc mais un organisme qui sert bien d’autres personnes. Essayons de comprendre d’abord pourquoi on fait des services volontaires. Il faut remarquer comment l’identité collective, que ce soit l’éducation, la question de race ou la situation économique, influence les vraies raisons pour lesquelles on participe au bénévolat. Puis, le discours déconstruit comment ces fondations superficielles créent une illusion morale nourrie par la …

L’Intégration De L’Immigré Africain Francophone Aux Etats-Unis Et En France : Opportunités Et Défis, Lily Calaycay

Honors Theses

Durant ces dernières années, l’immigration a considérablement augmenté dans plusieurs parties du monde, et par conséquent, l’intégration des immigrants dans la société est devenue un sujet largement discuté. Un immigré, selon la définition du Haut Conseil à l’intégration en 1991, est une personne résidant dans un pays qui est née dans un pays étranger (« Population immigrée » 96). Les mouvements migratoires africains ont une longue histoire, marquée par l’exploitation et la colonisation européenne du continent. L’histoire de l’immigration africaine est unique parmi les mouvements migratoires à cause des conditions qui ont accompagné un système brutal d’exploitation. La présence des …

Aging Is In The Eye Of The Beholder: Eye-Tracking And Person-Perception Analyses Of Young And Old Faces, Stephanie M. Ha

Honors Theses

To examine possible mechanisms related to negative attitudes of aging revealed in face processing patterns, young and old participants rated their first impressions (positive or negative) of 100 faces of young and old individuals taken from the CAL/PAL Fate Database (Minear & Park, 2004) while gaze patterns were recorded using eye-tracking methods. In a follow-up study, an independent sample of young participants rated the same 100 faces on competence, attractiveness, and subjective age in order to further assess age-related stereotypes. This study replicated the T-gaze pattern in previous eye-tracking studies (Firestone, Turk, Browne, & Ryan 2007). We also found evidence …

A New Almost Difference Set Construction, David Clayton

Honors Theses

This paper considers the appearance of almost difference sets in non-abelian groups. While numerous construction methods for these structures are known in abelian groups, little is known about ADSs in the case where the group elements do not commute. This paper presents a construction method for combining abelian difference sets into nonabelian almost difference sets, while also showing that at least one known almost difference set construction can be generalized to the nonabelian case.

From New York To The World : The American Jewish Committee And The Meaning Of India, 1945-1956, Ryan Charles Mcevoy

Honors Theses

In the 1940s and early 1950s, the American Jewish Committee (AJC) sought to develop an international vision in response to a world in flux. This project represents the first attempt to triangulate the relationship between India, Israel, and Jewish-American civil society, employing the case of India as a means for understanding the way in which the AJC shaped its worldview in the decade after World War II. Although Americans had been in contact with India well before the war, the AJC brought with it a unique lens for constructing meaning out of a new postcolonial space. A variety of factors …

Differential Privacy For Growing Databases, Gi Heung (Robin) Kim

Honors Theses

Differential privacy [DMNS06] is a strong definition of database privacy that provides indi- viduals in a database with the guarantee that any particular person’s information has very little effect on the output of any analysis of the overall database. In order for this type of analysis to be practical, it must simultaneously preserve privacy and utility, where utility refers to how well the analysis describes the contents of the database.

An analyst may additionally wish to evaluate how a database’s composition changes over time. Consider a company, for example, that accumulates data from a growing base of customers. This company …

Bleaching: Hierarchy And Commercialization In Contemporary Queer Club Culture, Harry Hoke

Honors Theses

The assertions of this work are rather broad: that there is a trend in a certain segment of queer nightlife towards hierarchy and commercialization, and that this may be a result of absorption of queerness into mainstream societal structures. As a first step in a research series, the purpose of this work is to establish that there is a trend in queer nightlife towards hierarchy and commercialization, and speculate about the potential consequences and manifestations of such a change. By establishing the presence and potential manifestations/consequences of hierarchy and commercialization within queer club culture, it is my hope that future …

Differential Equations Models Of Pathogen-Induced Single- And Multi-Organ Tissue Damage, Fiona Lynch

Honors Theses

The rise of antibiotic resistance has created a significant burden on healthcare systems around the world. Antibiotic resistance arises from the increased use of antibiotic drugs and antimicrobial agents, which kill susceptible bacterial strains, but have little effect on strains that have a mutation allowing them to survive antibiotic treatment, defined as “resistant” strains. With no non-resistant bacteria to compete for resources, the resistant bacteria thrives in this environment, continuing to reproduce and infect the host with an infection that does not respond to traditional antibiotic treatment.

A number of strategies have been proposed to tackle the problem of antibiotic …

The Progression Of Lyme Disease In The State Of Virginia, Margaret Michel

Honors Theses

Lyme disease has spread in the United States from the northeast to more southern and western parts of the country. It has been shown that the tick which most often carries the Lyme disease pathogen (Borrelia burgdorferi) in North America, Ixodes scapularis, has also spread to these new areas of concern. In Virginia, the disease has progressed from the eastern shore to the western, more mountainous regions. Through obtaining historical museum specimens of mice from 11 locations in Virginia, we seek to determine whether the Lyme disease causing pathogen, B. burgdorferi, has always been present in …

The Familiarity Factor: How Semantic Similarity Affects Associative Memory In Older And Younger Adults, Paige Warner

Honors Theses

The role of semantic knowledge and familiarity on retrieval processes were investigated in a test of the associative deficit hypothesis (ADH), and the data were interpreted from the perspectives of fuzzy trace theory and source monitoring errors (Naveh-Benjamin, 2000). Younger and older adults (N=60) studied pairs of words for two recognition tests – an item test, for recognition of individual words, and an associative test, for recognition of word pairs. In the associative test, four word pairs were presented with a forced-choice response requirement (4AFC; Patterson & Hertzog, 2010). In addition to the studied, intact cue-target pair, three cue-target pairs …

Investigating Medicinally Important Portein-Protein And Protein-Ligand Interactions : A Computational Approach, Cooper Ashley Taylor

Honors Theses

Molecular dynamics (MD) simulations and computational chemistry allow for an atomistic understanding of protein-protein and protein-ligand binding motifs. Through the use of MD, medicinally relevant complexes can be examined in detail unattainable by experimental methods. Within this work, systems pertinent to both Alzheimer’s Disease and HIV-1 are probed and thoroughly sampled to help elucidate potential therapeutic pathways. We used molecular dynamics and free energy estimations to gauge the affinity for the binary and ternary complexes of KLC1, APP and JIP1, three proteins all believed to be involved in the propagation of Alzheimer’s Disease. Two areas of thought exist suggesting that …

The College Admissions Problem: Effects Of Income And Ability Of Postsecondary Education Outcomes, Martha Whamond

Honors Theses

This paper examines the effects of students’ pre-college income on student outcomes and college admissions decisions. Under the assumption that colleges maximize utility by maximizing student outcomes, a two-stage regression model for student outcomes is building using data from the Integrated Postsecondary Education Data System (IPEDS) and the 1997 National Youth Longitudinal Survey (NLSY97). The first stage estimates a model for college quality using the IPEDS dataset. The college quality estimates are then used as independent variables in the second stage. The second stage estimates student outcomes as a function of pre- college income, ability, college quality, and demographic characteristics …

Toward A Scientific Investigation Of Convolutional Neural Networks, Anh Tran

Honors Theses

This thesis does not assume the reader is familiar with artificial neural networks. However, to keep the thesis concise, it assumes the reader is familiar with the standard Machine Learning concepts of training set, validation set, and test set [1]. Their usage is intended to help ensure that the Machine Learning system can generalize its training from input examples used during its training to “similar” kinds of examples never used during its training.

The concept of a Convolutional Neural Network (CNN) is one of the most successful computational concepts today for solving image classification problems. However, CNNs are difficult and …

Eating Your Feelings: The Relationship Between Core Affect And Food Choices, Kana V. Rolett

Honors Theses

The psychology of eating behavior is increasingly important given that more than one- third of Americans are obese, with 74% of men considered overweight or obese (Overweight and Obesity Statistics, 2012). This study examines the relationship between core affect and healthy food choices. Though previous research has examined relationships between specific emotions and eating behavior, little is known about core affect or about these relationships in more naturalistic settings (outside the lab). To evaluate the role of core affect in healthy food choices, a field study was conducted in the University of Richmond (UR) dining hall to measure UR students’ …

Do Obsessive Beliefs Moderate The Relationship Between Obsessive-Compulsive And Depressive Symptoms?, Joanthan A. Teller

Honors Theses

There has been limited research investigating potential mechanisms that drive the association between obsessive-compulsive (OC) and depressive symptoms. Obsessive beliefs are implicated in the etiology and maintenance of OC symptoms and have been shown to correlate with depressive symptoms amongst OCD patients. I assessed whether obsessive beliefs moderate the relation between obsessive compulsive and depressive symptoms to replicate analyses from a study conducted by Teller et al. (2017). Forty-six participants with elevated OC symptoms were recruited through Amazon’s Mechanical Turk. Each participant completed the obsessing subscale of the Revised Obsessive-Compulsive Inventory (OCI-R), Dimensional Obsessive Compulsive Scale (DOCS), the Revised Obsessive …

L’Expression Visuelle Durant La Seconde Guerre Mondiale : La Résistance, La Collaboration, Et Le « Juste Milieu », Jackie Sirc

Honors Theses

La Seconde Guerre mondiale a lancé un défi immense à l’humanité et au monde entier. Le niveau de violence était sans précédent et les conditions de vie ont changé complètement à travers l’immensité du combat. Une des choses qui a beaucoup changé était la production de l’art pendant cette période. Tandis que la violence du combat a eu une influence sur les thèmes et les sujets artistiques, le style du gouvernement en France devenait plus strict et règlementé. Par conséquent, la production de l’art, l’état de l’artiste, et la disponibilité de l’art pour le public se transformaient. Il y avait …

Study Of The Neutron Detection Efficiency Of The Clas12 Detector, Keegan Sherman

Honors Theses

One of the central physics goals of Jefferson Lab is to understand how quarks and gluons form nuclei. The 12 GeV upgrade is nearing completion and a new detector, CLAS12, is being built in Hall B. One of the approved experiments will measure the magnetic form factor of the neutron (Gn ). To make this measurement, the ratio of electron-neutron (e-n) to electron-proton (e-p) scattering events will be extracted from deuterium in quasi-elastic kinematics. A major source of systematic uncertainty is the neutron detection efficiency (NDE) of CLAS12. To better understand the NDE I used the Monte Carlo …
