Running For Home: Approaching Feminist Literary Theory Through A Biblical Lens In Women's Fiction, Tabitha Joy Lawson

Masters Theses

“Undeterred, Stephanie’s frown deepened. ‘Too bad you don’t have a mom. Maybe she could teach you how to be pretty’” (Lawson). These lines from the creative manuscript, Running for Home, capture a prevalent gender norm as eleven-year-old Eli attempts to navigate life in a new school. Gender norms as they apply to women, such as submissiveness versus independence, are a central theme of Women’s Fiction and is the genre of my creative manuscript. Written from the point of view of two characters, the story begins when Teresa is in her early twenties in 1974, and Eli’s begins in 1991. The …

The Heat Of The Moment: Rethinking The Endangered Species Act Amidst The Sixth Mass Extinction, Sarah Morton

Texas A&M Law Review

The biggest natural disaster facing humans today likely won’t be on the front page of the news. That doesn’t mean its impacts aren’t already being felt. Despite other disasters, like wildfires and hurricanes, dominating headlines, extreme heat is the leading cause of weather-related mortality in the United States. Even worse, extreme heat makes other natural disasters more severe and is decimating the Earth’s biological diversity at a rate that could soon become irreversible. The cost of widespread biodiversity loss is incalculable. Depleting ecosystems eradicates crucial services that nature provides for humanity, including clean air and water, food security, and cooling. …

Beyond "Bad Apples": Political Identity, Moral Interpretation, And Institutional Response To Abuse, Laura Werner

Student Theses

This thesis examines how psychological explanatory frameworks and structural institutional response interact to shape how domestic violence and sexual abuse are understood and addressed. Drawing on behavioral design theory and John Dewey's transactional approach to experience, I argue that harm is interpreted through mental models that simultaneously shape both individual perception and institutional action. Using survey data from 736 participants, I demonstrate that endorsement of the "bad apples" explanatory framework, attributing abuse primarily to a small group of deviant individuals, is predicted by psychological essentialism, belief in a just world, social dominance orientation, and political conservatism. These findings suggest that …

Learning With Geometric Priors In U-Net Variants For Polyp Segmentation, Fabian Vazquez, Jose A. Nuñez, Diego Adame, Alissen Moreno, Augustin Zhan, Huimin Li, Jinghao Yang, Haoteng Tang, Bin Fu, Pengfei Gu

Computer Science Faculty Publications

Accurate and robust polyp segmentation is essential for early colorectal cancer detection and for computer-aided diagnosis. While convolutional neural network-, Transformer-, and Mamba-based U-Net variants have achieved strong performance, they still struggle to capture geometric and structural cues, especially in low-contrast or cluttered colonoscopy scenes. To address this challenge, we propose a novel Geometric Prior-guided Module (GPM) that injects explicit geometric priors into U-Net-based architectures for polyp segmentation. Specifically, we fine-tune the Visual Geometry Grounded Transformer (VGGT) on a simulated ColonDepth dataset to estimate depth maps of polyp images tailored to the endoscopic domain. These depth maps are then processed …

When Swin Transformer Meets Kans: An Improved Transformer Architecture For Medical Image Segmentation, Nishchal Sapkota, Haoyan Shi, Yejia Zhang, Xianshi Ma, Bofang Zheng, Fabian Vazquez Jr.

Computer Science Faculty Publications

Medical image segmentation is critical for accurate diagnostics and treatment planning, but remains challenging due to complex anatomical structures and limited annotated training data. CNN-based segmentation methods excel at local feature extraction, but struggle with modeling long-range dependencies. Transformers, on the other hand, capture global context more effectively, but are inherently data-hungry and computationally expensive. In this work, we introduce UKAST, a U-Net like architecture that integrates rationalfunction based Kolmogorov - Arnold Networks (KANs) into Swin Transformer encoders. By leveraging rational base functions and Group Rational KANs (GR-KANs) from the Kolmogorov - Arnold Transformer (KAT), our architecture addresses the inefficiencies …

The Impact Of Property Tax Exemptions On The Hospital Real Estate Utilization, Howard Allen Levine

Doctoral Dissertations and Projects

This dissertation analyzes the effects of property tax exemptions on real estate utilization by hospitals in the production of medical services. Economic theory suggests that differential taxing creates inefficiencies causing destruction of wealth from deadweight loss. Property taxation is done by state and local governments. State and local governments spend 4.5 trillion dollars annually in the United States (Pustejovsky & Little, 2023, p. 2). Although only spending on services using real estate has efficiency effects due to real estate taxes, every 1% gain in overall efficiency is 45 billion dollars saved annually if the results can be generalized to all …

Rewoven Identity: The Stole As Material Agent In Twentieth-Century American Culture, Anastacia Rice

Doctoral Dissertations and Projects

This dissertation examines the stole as a material means of shaping identity in twentieth-century American society, tracing the movement across religious, cinematic, academic, political, and archival contexts. Traditionally understood as a liturgical vestment, the stole expanded in the modern era into fashion, performance, protest, and institutional ritual while maintaining a remarkably stable physical form. The study argues that the stole’s continuity is not the result of fixed tradition, but of ongoing material reconfigurations through which identity is produced, negotiated, and sustained. Rooted in material culture studies and guided by performance theory, fashion history, and archival methods, the dissertation presents rewoven …

The End Is Proof Of The Beginning: Heloise And Abelard The Unseen Architects Of Intention In Medieval Philosophy, Abby Brook Edwards

Doctoral Dissertations and Projects

The scandal surrounding the eleventh century love story of Peter Abelard and Heloise has eclipsed the depth of their individual intellects which has resulted in many scholars devoting their writings to the couple’s overly eroticized narrative. Following the castration, public humiliation, and academic ignominy of Abelard and after Heloise, a “fallen woman,” commissioned herself into a convent, the connection between tutor and tutee continued through written correspondence. Through an examination of their personal writings, this dissertation aims to expand upon the notion that Abelard was an eclipsed philosopher who should be standing alongside “giants in the field” of philosophy, but …

Canine And Equine Behaviors In Therapy: An Exploratory Multiple Case Study, Sarah E. Montano
