Effects of Critical Task Definition on U.S. Intelligence Community post-Conflict Information Structures
Advisor: Dennis Smith 
Information flows in the intelligence community influence what policymakers know, when they know it, and how they anticipate or react to stimuli in their security environment. While organizations develop various types of structures, from rigid hierarchies to informal networks, less attention has been paid to one significant aspect influencing those structures: agencies’ internal conceptions of purpose. The thesis examines the effects of critical task definitions – the activities agency employees perform on a daily basis – on U.S. intelligence community information structures. Case studies analyze changes during and after World War II and the Vietnam War, as well as the lack of change at the end of the Cold War. The thesis focuses on the Central Intelligence Agency, and on leader perceptions of broad or narrow jurisdiction. Evidence for cooperative or competitive information structures includes Congressional testimony, declassified agency documents, employee recollections in memoirs and biographies, and relevant media coverage.

Accessing the Right to Choose: Factors Predicting the Enactment of State-Level Abortion Clinic Access Laws
Advisor: Christine Nemacheck 
During the 1980s and 1990s, anti-abortion violence targeted at reproductive health clinics spiked in response to religious and political mobilization around the national decriminalization of abortion. To combat violence, harassment, and mass protests at clinics, some states enacted abortion clinic access laws. These laws typically prohibit certain activities, such as obstruction and vandalism, and some create no-protest buffer zones that restrict clinic protests. This research evaluates the context in which clinic access laws are enacted. It assesses the relationship between indicators of state abortion policy-making environments—levels of clinic violence, protests, and harassment, state abortion attitudes, anti-abortion interest group strength, state political ideology, and partisan control of the state government—with the likelihood that a state will enact an abortion clinic access law. Further, it explores how states balance free speech rights with abortion rights when enacting buffer zone laws.

Children of the Bible: “A Formula of Agreement” and Twenty-First Century Ecumenism
Advisor: Alexander Angelov
The 1997 document, "A Formula of Agreement," brought four Lutheran and Reformed denominations into full communion and ecumenical partnership.This Honors thesis explores the dialogue leading up to the agreement, and how this movement for Christian unity reflects changes brought about to the denominations by American culture, especially in regards to their interpretations of Scripture.

Virginia Woolf and the ‘Objective’ Camera: The Relationship Between Text and Image in Three Guineas and Orlando
Advisor: Simon Joyce
Though photography offers a claim to objectivity that writing and painting cannot ostensibly equal, Virginia Woolf’s Three Guineas and Orlando: A Biography argue that the camera is not an unmediated form of documentation. Three Guineas’ images of a patriarchal society and Orlando’s more personal portraits reflect their photographers’ inherent subjectivity, and the photographs’ placement in and relationship with the texts further question the veracity of representation. Whereas Three Guineas derives its power from the contrast between reproduced and described photographs, Orlando uses images to present a counter-narrative contradicting the purported reliability of biographical accounts.

Supporting Meaningful Career Paths: Effects of Mentoring and Adulthood Perception on Vocational Outcomes for Emerging Adults
Advisor: Elizabeth Raposa
During the transition to adulthood, adolescents are faced with developmental tasks such as an increase in risk-taking, academic pressure or low self-esteem. Naturally-occurring relationships with supportive non-parental adults (i.e., natural mentors) can aide in providing guidance as well as emotional support (Ahrens et al., 2008). The present study examined how mentors during adolescence shape vocational outcomes during early adulthood, and whether this impact of mentoring can be explained by changes in perceived adulthood. Analyses used data from a large, nationally representative sample, the National Longitudinal Study of Adolescent Health (Add Health). Results suggested that youth ratings of closeness with their natural mentor predicted higher perceived adulthood (p < .001). Youth who identified as having higher perceived adulthood reported pursuing higher levels of education (p < .001), job satisfaction (p < .001) and age at first full-time job (p < .05). These results suggest that naturally-occurring relationships predict perceived adulthood and improved vocational outcomes.

Althea Hunt: Behind the Curtain
Advisor: Leisa Meyer
Althea Hunt is not a name well known outside of Phi Beta Kappa Hall. Yet, she pioneered the establishment of William and Mary theatre as a single, female professor in 1926. Hunt never married, nor did she have children during an era in which this was an expectation of upper-middle class women.  Hunt provides an insight to nontraditional womanhood and the power of positive teaching and directing as an independent woman. Her close relationships with her students through and beyond their time at William and Mary exemplify the ideal professorship that created a firm foundation to the theatre department still in existence on campus today.

Lacustrine Records of Holocene paleoenvironmental Change From the Lofoten Islands, Norway
Advisor: Nicholas Balascio 
Lake sediments are useful paleoenvironmental archives; however their sensitivity depends on lake and catchment-specific characteristics. For my honors thesis, I'm analyze sediment records from two contrasting lakes on Vestvågøy in the Lofoten Islands, Norway to investigate region-specific influences of Holocene climate changes and human-driven landscape evolution. Sediment cores spanning the last c. 7.5 ka were collected from Lauvdalsvatnet, a small lake with a steep-sided catchment and large catchment to lake area ratio, and Ostadvatnet, a larger lake with a smaller catchment to lake area ratio and lower slope catchment. Sediment analyses include magnetic susceptibility, organic matter content, bulk density, biogenic silica, carbon to nitrogen ratios and scanning X-ray fluorescence data. Chronologies are based on radiocarbon dating of terrestrial macrofossils. Our results have implications for understanding how the Lofoten region responds to global climate changes, and the spatial extent of human landscape impacts on Vestvågøy through time.

A Mathematical Model of Economic Growth of Two Geographical Regions 
Advisor: Junping Shi
A mathematical model of coupled differential equations is proposed to model economic growth of two geographical regions (cities, regions, continents) with flow of capital and labor between each other. It is based on two established mathematical models: the neoclassical economic growth model by Robert Solow, and the logistic population growth model. The capital flow, labor exchange and spatial heterogeneity are also incorporated in the system. The model is analyzed via equilibrium and stability analysis, and numerical simulations. It is shown that a strong attraction to the high capital region can lead to unbalanced economic growth even when the two geographical regions are similar. The model can help policy makers to decide whether the region should have an open economy or a more closed one. The results of the model can predict the trend of the trade between regions and provide a new insight into some hotly debated contemporary controversial topics.
