“Tyranny” As Concept: Semantic Change And The Formation Of Colonial Political Consciousness In The New Hampshire Gazette, 1756–1783, Antonio Worley May 2026

“Tyranny” As Concept: Semantic Change And The Formation Of Colonial Political Consciousness In The New Hampshire Gazette, 1756–1783, Antonio Worley

All Theses

Historians of the American Revolution have frequently viewed terms such as tyranny as a stable ideological category, associated with corruption and resistance to arbitrary power. This thesis instead reconceptualizes ‘tyranny’ as an evolving and historically contingent Koselleckian concept. Drawing on a comprehensive analysis of the New Hampshire Gazette from 1756 to 1783, this study combines close reading with computational methods, including word frequency analysis and word embeddings, to chart the evolution of the semantic field surrounding “tyranny” over time.

Prior to the Stamp Act of 1765, ‘tyranny’ was used primarily in a religious and moral framework which was shaped by …


Desert Ghost, Jessica Downs May 2026

Desert Ghost, Jessica Downs

All Theses

This thesis explores the relationship between landscape, memory, and the body through handmade paper installations inspired by the deserts of southwestern Utah. Drawing from personal experience of place and the loss of a childhood home, the work considers how environments are internalized and persist as shifting, sensory impressions rather than fixed geographies. The desert becomes a generative site for examining presence, transformation, and the passage of time, both geologic and personal.

I use handmade paper and installation to translate my experience of place into physical form. Paper serves as both material and metaphor; its fibers, textures, and muted tones emulate …


The Cost Of Her Journalism: Technology-Facilitated Gender-Based Violence Against Women Journalists In The Former Soviet Union Countries, Kamila Eshalieva May 2026

The Cost Of Her Journalism: Technology-Facilitated Gender-Based Violence Against Women Journalists In The Former Soviet Union Countries, Kamila Eshalieva

All Theses

Although offline gender-based violence has been studied for decades, technology-facilitated gender-based violence (TFGBV) remains a prevalent yet underrecognized phenomenon. Journalism is a field in which this form of violence is especially persistent, and women journalists face disproportionate targeting. From cyberbullying and harassment to doxxing and disinformation, TFGBV comes in a myriad of forms, each leaving lasting scars on reporters who already face elevated professional risks. The post-Soviet region is particularly concerning, given its history of repressive regimes and hostile environments for journalism. While technology has expanded the ways for new forms of violence to emerge, these incidents are often not …


The British Are Coming; Effects Of The American Revolution On Charlestonian’S Importation Of Furnishings, 1765-1800, Summer B. Henry May 2026

The British Are Coming; Effects Of The American Revolution On Charlestonian’S Importation Of Furnishings, 1765-1800, Summer B. Henry

All Theses

On the eve of the American Revolution Charleston’s ties to Great Britain, particularly London, were far greater than any other colonial city in America. Charlestonians of means traveled to the ‘mother country’ with frequency, sent their sons to be educated there, and were highly influenced by what was fashionable in London, for both home and person.

This study looks at what effects the American Revolution had on Charlestonians importation of furnishings and material goods beginning in 1765 as anti-British sentiment began to take hold in America, through 1800, a time when Charleston was rebuilding going into the Federal era. The …


Portrayals Of Miscarriage In Film And Television: A Qualitative Analysis, Geovana Leonetti Saraiva May 2026

Portrayals Of Miscarriage In Film And Television: A Qualitative Analysis, Geovana Leonetti Saraiva

All Theses

Entertainment media may serve as a primary source through which individuals learn about miscarriage; however, little research has examined how miscarriage is portrayed in film and television. This study addresses this gap by conducting a textual analysis of five films and five television shows using a constructivist grounded theory approach. Guided by the model of stigma communication (MSC), communication privacy management theory (CPM), and social support frameworks, the analysis explores how miscarriage is represented in entertainment media.

Findings indicate that the analyzed content frequently includes stigma-related cues—such as marks, labels, responsibility, and peril—that may contribute to the formation and reinforcement …

Biology, Ecology And Control Of Eye Gnats In An Open Pine Ecosystem, Leela Hospach May 2026

Biology, Ecology And Control Of Eye Gnats In An Open Pine Ecosystem, Leela Hospach

All Theses

Eye gnats of the genus Liohippelates are bothersome flies of the family Chloropidae. They breed in moist, disturbed, sandy soils that contain organic matter, and have been implicated as vectors of conjunctivitis, bovine mastitis, and yaws. We conducted research into some basic biological and ecological characteristics. Using wild-caught gnats in a temperature-controlled incubator, we found that their activity peaks between 27°C and 41°C. Trapping at different heights above the forest floor in an open-pine savannah, we captured most gnats at 7.5 m off the ground. This may have to do with the attractiveness of the rotten egg lures we used, …


Anxiety And Intuitive Eating: Examining Dispositional Mindfulness As A Protective Factor, Jordan Signorelli May 2026

Anxiety And Intuitive Eating: Examining Dispositional Mindfulness As A Protective Factor, Jordan Signorelli

All Theses

Intuitive eating (IE) is an anti-diet approach focused on listening to internal hunger and fullness cues and is associated with reduced disordered eating patterns and improved dietary intake. However, anxiety negatively impacts IE. Dispositional mindfulness (DM) – one’s innate, present-centered, nonjudgmental awareness of thoughts, emotions, and bodily sensations – is associated with lower anxiety and greater IE. Yet, whether DM mitigates the negative impact of anxiety on IE remains underexplored. Grounded in the Cognitive Behavioral Therapy Framework, this study aimed to: 1) examine the relationship between anxiety and IE, 2) examine the relationship between DM and IE, 3) examine whether …

Stochastic Universal Differential Equations For Epidemiological Modeling: Uncertainty Quantification In Disease Transmission Dynamics, Alice Menaya Armah-Bonney May 2026

Stochastic Universal Differential Equations For Epidemiological Modeling: Uncertainty Quantification In Disease Transmission Dynamics, Alice Menaya Armah-Bonney

Electronic Theses and Dissertations

Epidemic forecasting requires not only predictions of expected case counts, but also quantification of uncertainty, although existing surrogate modeling frameworks for agent-based models remain fundamentally deterministic. In this thesis a Stochastic Universal Differential Equation framework is presented that extends the deterministic Universal Differential Equation approach by incorporating a learnable stochastic diffusion term, enabling calibrated probabilistic forecasts while preserving the mechanistic interpretability and computational efficiency of the deterministic baseline. In doing so, a two-phase training algorithm is introduced to ensure stable convergence and the framework is validated against the ensemble output from ExaEpi, an exascale agent-based model of a COVID-19 outbreak …

Attendance Matters: Incentive Programs And Chronic Absenteeism In Elementary Schools, Aubryn Street May 2026

Attendance Matters: Incentive Programs And Chronic Absenteeism In Elementary Schools, Aubryn Street

Electronic Theses and Dissertations

Chronic absenteeism is a common challenge in elementary education. Schools often use attendance incentive programs, such as rewards or recognition, to encourage students to attend regularly. However, it is not always clear whether these programs actually improve attendance. This study examined whether attendance incentive programs are effective and how school staff view and use these programs.

This mixed-methods study used both school attendance data and interviews with school personnel. Attendance data from two school years showed that schools with incentive programs did not have lower absenteeism rates than schools without them. However, attendance improved overall from one year to the …

Structured Representation Learning For Generalizable Deepfake Video Detection, Maowen Tang May 2026

Structured Representation Learning For Generalizable Deepfake Video Detection, Maowen Tang

All Theses

Deepfake video detection has become an important problem in multimedia forensics as modern generative models produce increasingly realistic facial manipulations. Although many existing detectors achieve strong performance on the datasets on which they are trained, their performance often degrades substantially on unseen manipulation methods and evaluation conditions. A major reason for this limitation is the premature collapse of spatial structure: many vision transformer based detectors aggregate patch tokens into a single global representation, thereby suppressing the localized and temporally uneven forensic cues that characterize manipulated video.

This thesis presents the Spatio-Temporal Slot Aggregation Network (ST-SAN), a video-level deepfake detection framework …


Bitcoin Options Risk-Reversal Predictability, Meng Hwee Neo May 2026

Bitcoin Options Risk-Reversal Predictability, Meng Hwee Neo

Dissertations and Theses Collection (Open Access)

This dissertation examines whether Bitcoin options risk-reversal (RR) spreads predict future Bitcoin returns, using daily Deribit data from April 2021 to December 2025 (1,723 observations).

In the primary 25-delta, 90-day specification, the RR coefficient is significant at the 1% level in a thirteen-variable baseline regression with Newey–West standard errors. Robustness tests across all available delta–tenor specifications show statistically significant RR coefficients in the majority of configurations, concentrating in the 30–180-day maturity band.

The butterfly spread (BF) also predicts returns. Both remain significant after controls are added: the RR t-statistic increases from 1.91 (univariate) to 3.73 (full baseline), and the BF …
