Size Discrimination In Goldfish (Carassius Auratus), Johnna Patrick

Theses & ETDs

Quantitative abilities in fish have been previously observed, including in natural behaviors such as shoaling and various laboratory tasks. Two-choice visual discrimination tasks require individuals to differentiate between stimuli, and when conditioned, individuals can demonstrate learning of stimulus value. The concept of understanding ordinal relationships has been reported in goldfish (Carassius auratus) before, although no studies have explicitly tested primarily size discrimination. The current study tested four goldfish on their ability to perceive and swim through large vs. small holes, using an adapted methodology and expansion of similar literature. It also tested what the goldfish were learning during the discrimination …

Time As A Constitutional Constraint: Resolving The Circuit Split On Prolonged Fourth Amendment, Ian Seabrooks

Washington Law Review Online

The Fourth Amendment of the U.S. Constitution states, “[t]he right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated. . . .” Some circuits, like the Ninth and D.C. Circuits, have interpreted the Fourth Amendment’s reasonableness standard to apply beyond just the initial seizure of property but also to include the continued retention of the seized property. Other circuits, such as the First, Second, Sixth, Seventh, and Eleventh Circuits, have read the reasonableness standard more narrowly and interpreted this requirement to pertain only to the original seizure. …

Monkeywrenching The Curriculum: Curricular Subversion As An Act Of Care, Matthew Clay Ph.D., Paul Parkison

Teacher Education Faculty Publications

This conceptual analysis suggests that the practice of monkeywrenching, borrowed from environmental activism, can serve as an action by teachers to address this challenge. Monkeywrenching consists of direct action subversion, applied to curricula for the sake of specific students, and is constituted as an act of care as described by Nel Noddings. Specific consideration of sustainability education indicates that curriculum subversion through monkeywrenching can be a powerful tool in demonstrating care for place and students.

Brilliance Bias In Generative Ai, Juliana Shihadeh

Engineering Ph.D. Theses

Generative AI models, like Midjourney, Stable Diffusion, and GPT have been shown to reinforce harmful biases, often perpetuating outdated and discriminatory stereotypes. This thesis examines a largely overlooked bias in AI systems: Brilliance Bias. By age six, many children begin to internalize the damaging notion that intellectual brilliance is a male trait — a belief that persists into adulthood.

This thesis consists of three studies that assess brilliance bias in generative AI. The first explores the behavior of popular text-to-image models when given intelligence-based prompts such as “brilliant” and “genius.” In particular, we seek to explore whether the models produce …

Universal Sound Separation: Distance-Aware Mixture Simulation, Co-Occurrence Conditioning, And Chain-Of-Inference, Wonjun Park

Computer Science and Engineering Theses - Archive

Universal Sound Separation (USS) -- the task of disentangling arbitrary sound sources from a single-channel acoustic mixture -- remains an open challenge due to the ill-posed nature of the problem and the distributional gap between synthetic training data and real-world recordings. This thesis addresses three distinct bottlenecks in the USS pipeline: training data realism, inference strategy, and conditioning richness. We first present two knowledge-guided approaches to sound source separation. The first is a distance-aware mixing strategy that leverages Large Language Models (LLMs) to assign plausible loudness relationships between audio sources during training data synthesis. By querying an LLM about the …

Peptide Sequencing Via Protein Language Models, Thuong Le Hoai Pham

Computer Science and Engineering Theses - Archive

Protein sequencing is fundamental to understanding biological processes, disease mechanisms, and therapeutic developments. Current protein sequencing techniques, primarily relying on mass spectrometry and Edman degradation, face significant limitations in accurately identifying all amino acids within a protein, hindering comprehensive proteome analysis. Recent advances in click chemistry and bioorthogonal chemistry have enabled the identification of specific amino acids and their positions within a peptide; however, these techniques are still limited by the number of amino acids that can be identified with high accuracy and specificity, resulting in partially known sequences. This thesis presents a novel computational approach that leverages protein language …

Enjoying The Golden Screen Of Asian American Representation In A Colorblind Era: Neoliberalism, Narrative, And Negotiation, Jered Mabaquiao

English Dissertations - Archive

This dissertation contributes to Asian American studies, Cinema and Media Studies, and Critical Theory by interrogating how contemporary Asian American representation is shaped by the intertwined pressures of racial politics, neoliberal market demands, and psychic life. Working across race studies, media studies, psychoanalysis, and phenomenological questions of ontology and being, the project argues that Asian American film and television cannot only be understood  through the language of popular culture representation, narrative progress, media visibility, or political inclusion. Instead, I combine such angles to examine how popular culture media participates in the contradictory production of Asian American subjectivity as culturally present …

Nurse-Led Interventions To Reduce Occupational Hand Injuries In Manufacturing, Patti Harter

Doctor of Nursing Practice (DNP) Scholarly Projects - Archive

Occupational hand injuries cause preventable morbidity, lost productivity, and workers’ compensation costs in manufacturing. Although safety policies and personal protective equipment (PPE) are in place, inconsistent glove use, slow hazard identification, and delayed response still cause injuries. This quality improvement (QI) project evaluated an eight-week, nurse-led injury-prevention bundle at a Texas heavy-vehicle manufacturing facility. The intervention required daily glove inspections, Safety Champion participation, real-time electronic hazard reporting, and corrective action within the shift. Injury outcomes were measured using Occupational Safety and Administration (OSHA) rates per 200,000 work hours and percentage change from baseline. After implementation, hand injury rates fell from …
