The Tur Nout Effect: Challenging The Median Voter Theorem, George Thomas Rogers

Theses and Dissertations

The classical Median Voter Theorem (MVT) predicts that, in a two-party system with majority rule, candidates will converge toward the ideological center to capture the median voter. This logic, grounded in spatial models of political competition, assumes full voter participation and fails to account for the growing ideological polarization in modern democracies. This thesis reevaluates the MVT by incorporating probabilistic turnout into a utility-based model of voter behavior. It theorizes that turnout is shaped not only by ideological proximity but also by expressive motivations, including both strong affinity and strong aversion to candidates. A novel measure of turnout utility is …

Between Florida And The World: Young People And The Politics Of Citizenship, Jessica Flach

Theses and Dissertations

This thesis critically examines how American high school students experience and make sense of global citizenship within the context of a commercial educational tour. Drawing on a case study of students from a Title I public high school in Florida, the research interrogates the narratives of civic transformation promoted by educational travel companies and explores how these narratives intersect with students’ lived realities. Combining ethnographic methods, interviews, and critical discourse analysis, the study reveals that global citizenship is not meaningfully realized through such travel experiences; rather, it is fragmented, depoliticized, and often disconnected from the civic education students receive in …

Addressing Key Challenges In Mhz Power Converters, Aqarib Hussain

Theses and Dissertations

Power electronics are essential in applications such as aerospace, electric vehicles, and electric ships where compact, efficient, and high power-density converters are increasingly demanded. This push toward miniaturization has led to converter designs operating at switching frequencies in the megahertz (MHz) range. Higher-frequency operation enables significant reductions in passive component sizes—particularly transformers and inductors—thereby facilitating dense packaging. However, these benefits come with new challenges, including increased thermal stress, complex semiconductor behavior, higher-frequency magnetic design constraints, and elevated electromagnetic interference (EMI).

This research addresses several key challenges in MHz converter design. The first part involves the development of a 1-MHz, 1-kW …

A Spatial Scan Statistic For Group Testing Data, Vincent Onyame

Theses and Dissertations

Group testing involves pooling specimens from multiple individuals and offers an efficient means to surveil low-prevalence pathogens, but poses challenges for spatial cluster detection when only pooled results are observed. In this thesis, we develop a spatial scan statistic tailored to group-testing data with variable pool sizes. The statistic compares a null hypothesis of a homogeneous infection rate across all clusters to an alternative hypothesis that infection probabilities differ inside and outside a candidate cluster, with both models fitted by maximum likelihood estimation. We approximate the null distribution of the maximum likelihood ratio test via Monte Carlo simulation.

Assessing Health And Academic Disparities In The Deep South: The Enduring Impact Of Segregation And Redlining In Georgia, Bridget Hamilton

Theses and Dissertations

Background: Within the American South, marginalized Black populations continue to suffer from health disparities. A key resource that could aid in the prevention of health disparities such as teen pregnancy is the school nurse. School nurses are well positioned to assist in the development of independent health maintenance among student populations. However, school nurses remain understaffed and underfunded throughout most of the United States, which limits their effectiveness. It is possible that within southern states there are inequities in how school resources are allocated that have ties to segregation and redlining practices that systemically marginalized Black populations throughout the 1900s. …

Investigating The Role Of Metallothioneins In Fungal Iron Homeostasis, David Eap

Theses and Dissertations

The pathogenic fungi Aspergillus fumigatus requires metals to survive and infect humans, but metal overload can be detrimental. Metallothioneins (MTs) are small, cysteine-rich proteins that alleviate metal toxicity by binding excess metals (typically Zn or Cu) for storage or delivery. A recent report indicates that the Fe-S cluster binding glutaredoxin GrxD and the putative Cu-MT CmtA were interacting under high iron conditions in A. fumigatus. We hypothesize that this MT may have a role in binding iron or Fe-S clusters under iron overload conditions to prevent iron toxicity. We also aim to characterize this new MT by determining its …

Reduced Order Model-Based Framework For Microsecond Model Updating Of Two-Dimensional Structural Systems Using The Local Eigenvalue Modification Procedure, Emmanuel Abiodun Ogunniyi

Theses and Dissertations

Real-time model updating is crucial for active structures and electronic assemblies subjected to high-rate dynamic events. High-rate dynamic events refer to events that occur at high speeds and with rapid changes in the forces and energy involved. These events can include explosions, impacts, and crashes. These systems are characterized by a high dynamic response with a high rate (< 100 ms), high amplitude (> 100 gn), highly nonlinear, meaning that the response is not proportional to the applied force, and involve complex interactions between multiple objects or materials. A system exposed to high-rate dynamic environments is frequently prone to rapid plastic deformation, involving violent and …

Naqbu: Cosmological Undercurrents In Sumer And Akkad, Fiona Eirene Andrews

Theses and Dissertations

The concepts of primordial incomprehensibility, ordered creation, and the liminal chaos between them, form a foundational framework in Mesopotamian intellectual culture. The distinctive ways in which these concepts manifest in Sumero-Akkadian cultures suggest a systematic cosmological substructure — characterized by the paradoxical, cyclical, and co-creative relationships between forces such as Infinity and measure, generation and destruction, and definition and obscurity — that remains insufficiently examined in current scholarship. Drawing from diverse corpus of Mesopotamian creative works, Kabbalistic exegesis, and post-modern scholarship, this thesis seeks to elucidate the essential dynamics within that substructure. By proposing a semiotic hermeneutical strategy attuned to …

Democracy’S Sanctuary: Highlander Folk School’S Campaign For Justice From The Labor Movement To The Civil Rights Movement, 1932-1962, Alexandra Elizabeth Bethlenfalvy

Theses and Dissertations

A sanctuary for political democracy, the Highlander Folk School was established in 1932 as a center for community activism, serving as the leading labor union organizing site in rural Tennessee during the Great Depression.

Editing Japan: Pornography Commentary As Postcolonial Revenge In China's Digital Sphere, Yichi Zhang

Theses and Dissertations

This study examines how Chinese male audiences reconstruct postcolonial masculinity through the consumption and reinterpretation of Japanese pornography. By analyzing commentary videos produced by "Team Strawberry," I argue that this phenomenon constitutes a symbolic revenge against Japan's historical dominance. Through degrading Japanese female performers and mocking Japanese culture and male actors, Chinese viewers invert colonial hierarchies, transforming sexual consumption into a nationalist project. However, this mimicry of colonial violence ultimately reinforces patriarchal structures rather than subverting them, while also framing nationalism through sexual conquest that mimics collective historical trauma. The re-editing and mocking of Japanese pornography by Chinese content creators …
