The Effects Of Low Stimulating Music Vs. High Stimulating Music On Visual And Auditory Reflexes In Young Adults, Monabelle Elbayeh, Vania Galindo, Ria Modi, Gianna Montelongo

Posters - 2026

This study investigates the effects of high-stimulating versus low-stimulating music exposure on human reflexes, specifically examining how different levels of auditory stimulation influence reaction time. Music is known to impact cognitive and motor performance, but its direct effect on reflex responses remains less understood. In this experiment, participants are exposed to high-stimulating music and low-stimulating music in separate trials, with reflexes measured before and after each condition using visual and auditory tests in the LabScribe program. It is hypothesized that after listening to high-stimulating music for five minutes, individuals will demonstrate shorter reaction times compared to after listening to low-stimulating …

Untangling G-Quadruplexes In Dna: The Effects Of Nucleotide Excision Repair, Jaidelin Alvardo, Abiageal Riley, Erick Morales Orrante, Raynne Malik

Posters - 2026

Nucleotide Excision Repair (NER) remo ves bulky DNA lesions that are attributed to UV irradiation, environmental mutagens, and chemo-therapeutic agents (Schärer, CSH Perspectives Biology, 2013). G4- quadruplexes are formed by four guanines hydrogen bonded together to form a planar ring, and stacking of the hydrophobic G quartets stabilizes the quadruplex structure Capra et al.,PLoS Computational Biology, 2010). A surplus of this structure is linked to genomic Instability and cancer development.

Prior studies indicate that because NER eliminates large lesions of DNA, there may be a link to the removal of G4-quadruplexes through Nucleotide Excision Repair (De Magis et al, Nature,2020). …

Mapping Sensory Landscapes: Distribution And Arrangement Of The Anterior Lateral Line System In Texas Catfish, Tatiana K. Flores, Ruben Tovar

Posters - 2026

Fish have a system of sensory organs known as the lateral line system. This system contains numerous mechanoreceptive neuromasts and electroreceptive ampullary organs (Northcutt et al, 2000). Neuromasts are small, hair-like structures located within canals in the lateral line system just under the fish’s skin and are open to the environment through small pores visible on its skin (Parker, 2025). Water flows into these canals through the pores which stimulates the sensitive hair cells, resulting in electrical signals sent to the fish’s brain. The brain interprets these signals and creates “images” of the fish’s surroundings, helping it to see even …

Does Habitat Predict Head Shape? A Comparative Geometric Morphometric Analysis Of Eurycea Spp., Sarah Flores-Garza, Alexa Miner, Gianna Montelongo

Posters - 2026

Subterranean environments impose strong selective pressures, including complete darkness and reliance on non-visual sensory systems. In Eurycea salamanders, these conditions are associated with traits such as reduced eyes and expanded head regions that improve sensory detection (Tovar et al., 2025). Subterranean species are often expected to share similar head shapes due to convergent evolution. However, not all species experience these pressures equally. Eurycea latitans is a polymorphic species that inhabits both surface and cave environments. Eurycea sp._NB is an obligate subterranean species, while Eurcyea sosorum is a surface species. This study tests whether habitat predicts head shape in Eurycea, or …

Bird Population Response To Abiotic And Biotic Stresses In Urban & Restored Oak Savannah Habitat, Annabelle Ball

Posters - 2026

Birds are heavily impacted by urban development. Many experience habitat fragmentation and removal of food sources. However, other species can adapt to and even thrive in urban environments, thanks to certain tree species, bird feeders, and buildings. In North America, the house sparrow and the European starling are invasive species that benefit from urban environments (Bartelt, 2011; Fitzwater, 2014). Meanwhile, many habitats across the continent are experiencing restoration/rewilding efforts for the benefit of birds. One such habitat is the oak-savannah, which is characterized by 10-30% canopy cover and a mixture of prairie & woodland vegetation, supporting a high diversity of …

"I Need Help!": Can Ashwagandha Reduce Inflammation-Driven Oxidative Stress Without Inducing Cytotoxicity In Macrophages?, Caitlyn Pinaga

Posters - 2026

Ashwagandha has been shown to reduce inflammation in humans by lowering pro-inflammatory cytokines and oxidative stress markers, helping regulate immune responses. It is commonly used to support conditions linked to chronic inflammation, such as stress-related disorders, arthritis, and metabolic imbalance. THP-1 macrophages are a part of the body's immune response to inflammation. While they produce a lot of different responses to inflammation, one of them is the production of Reactive Oxygen Species (ROS). N-acetylcysteine (NAC) is established to be a powerful antioxidant and is used as a positive control. My study aims to understand how ashwagandha, a popular supplement, affects …

Human Advisors Or Ai Algorithms? How Loneliness And Age Impact Trust In Consumer Evaluations Of Services, Kevin Newman, Ainslie Schultz

AMTP Proceedings 2026

This research investigates how loneliness and age shape trust and consumer evaluations of services that provide personalized advice through human versus Artificial Intelligence (AI) recommenders. Across three experimental studies, our findings show that loneliness increased trust and consumer evaluations for services using human- (vs. AI-) based) recommenders among younger adults, but this pattern reversed among older, more lonely adults. Among these individuals, loneliness led to more positive consumer evaluations of a service using an AI-based (vs. human) recommender. Guided by the Evolutionary Theory of Loneliness (Cacioppo & Cacioppo, 2018), these findings suggest that younger lonely consumers exhibit approach motives …

Against A Medical Exception To Equal Protection, Govind Persad

Washington and Lee Law Review

Government regulations of medicine sometimes treat patients differently based on their race or sex. Does heightened scrutiny apply to such regulations—as is usual when law treats someone differently based on a protected characteristic? Or is there a medical exception to equal protection?

Recently, in United States v. Skrmetti, the Supreme Court upheld a law that restricted access to medical treatments for transgender minors. Though its holding did not rely on medical exceptionalism, its discussion reinvigorated interest in a “medical exception” to equal protection: that medical decisions are exempt from the searching review applied when governmental decisions consider protected characteristics.

Addiction And Dalits: The Impact Of India’S Caste System, Ava Jackson

Audre Lorde Prize

Across global public health and psychology, addiction is defined as a chronic condition that involves compulsive seeking and taking of a substance. In Western frameworks, addiction is often treated as an isolated condition, where the individual is blamed for their actions. In reality, addiction is rooted in biological, psychological, and social factors and is more complex than an individual level. Looking at the Global South, addiction is prominent in Dalit or “untouchable” individuals in India’s caste system, who face exclusion from all forms of society, including education, work, and social experiences. Addiction among Dalit women in India, Bangladesh, and the …

Exploratory Evaluation Of Handler Performance And Processing-Related Outcomes During Cattle Handling, Morgan Marquardt

Department of Animal Science: Dissertations, Theses, and Student Research

Animals have several critical roles in society, including the production of food and fiber, and companionship. Contact with animals has been shown to benefit human physical and mental health, yet little research has investigated the impact that humans have on animals. Handler skill may considerably affect the extent to which humans influence animal health and wellbeing, and this may be a critical consideration for animal agriculture. Objective assessment of cattle handler skill has received limited attention in the scientific literature, despite its importance to human safety and animal welfare. When compared to less skilled handlers, highly skilled cattle handlers may …

Resonant Cracks In The Music Curriculum: Integrating Social And Emotional Learning In The Secondary Music Classroom, Margaret E. Lerch

Education Doctorate Dissertations

Music education has long been recognized as a subject that encourages student learning beyond the walls of the music classroom. While elementary music programs often foster language development and social awareness, secondary music instruction tends to emphasize performance skills and technical development. The explicit secondary orchestra curriculum for this middle school includes only instrument skill-development standards and learning-target descriptions. In this fourth-marking-period sixth-grade orchestra class, coursework—including students’ journal reflections, classroom dialogue, and comparison soundscape projects—operated intentionally “within the cracks” of the formal curriculum to create opportunities for the students to express and engage with emotions, identity, belonging, empathy, perspective-taking, and …

A Thermal-Hydraulic Study Of Bio-Inspired Fractal Microscale Heat Sink Using Computational Fluid Dynamics, Aagam Shah

Master’s Theses - College of Engineering

In recent years, the demand for efficient thermal management in miniaturized and high-performance electronic devices has grown rapidly. As electronic devices become more compact and powerful, their heat dissipation density increases, requiring more innovative and efficient thermal management solutions. Among the most promising solutions for localized cooling are micro-scale cold plates, which have been widely studied since their introduction in the early 1980s [1]. These devices, due to their small footprints and high surface-to-volume ratios, are highly suited for cooling microprocessors, sensors, and integrated circuits. However, one major limitation of conventional microchannel cold plates is their high pressure drop characteristic, …

Disparities Between Chronological And Biological Age: A Biocultural Analysis Of Aging In Contemporary Populations, Nicollette S. Appel

Anthropology ETDs

This dissertation investigates how structural and cultural factors collectively influence the aging process and how these effects manifest in both hard and soft tissues. Chapter 2 used an AI-based CT body composition tool and a CT-based biological age model to examine the relationship between age discrepancy and demographic variables such as sex, race/ethnicity, and manner of death. Results demonstrate significant differences in age discrepancy, with females, Native Americans, and individuals who died of natural causes exhibiting greater discrepancies. Chapters 3 and 4 further evaluate whether anthropological approaches to skeletal aging can be improved by adopting a biocultural perspective. These chapters …

Targeting The Metabolic-Neurodegenerative Axis: In Silico Repurposing Of Fda-Approved Pleiotropic Metabolic Modulators For Alzheimer's Tau Protein, Maanya Chitrapu, Juhi Vora

Undergraduate Student Symposium

Extensive research has established a link between insulin deficiency and insulin resistance and Alzheimer's Disease (AD) type-neurodegeneration, coining it "Type 3 Diabetes". While research typically focuses on glucose regulation, the comparative structural efficacy of broader metabolic agents against neuropathology remains distinctively underexplored. This study addresses this gap by performing a novel in silico comparison of three drug classes (Glucose, Lipid, and Cardio-Metabolic regulators) to identify superior scaffolds for obstructing the pathological Tau protein, which plays a major role in causing AD through its hyperphosphorylation. The Tau paired helical filament (PDB ID: 5O3L) was retrieved from the RCSB Protein Data Bank. …
