The Relationships Among Orthorexia Nervosa, Perfectionist Tendencies And Academic Achievement In Nutrition And Dietetics Students, Sophia Grace Owens

Master's Theses

Eating disorders can cause a disturbance in how the health of food is viewed (Cerniglia et al., 2017). If a person has disturbances in their eating behaviors that can cause harm to their health, but the behaviors do not fit into the criteria of a specific eating disorder, they fall into the category of a disordered eating pattern (Academy of Nutrition and Dietetics, 2018). Because of the stress the college environment can cause students, some college students may cling to anything they can control, which may be reflected in their dietary habits. Orthorexia Nervosa (ON), a disordered eating pattern, is …

The Impact Of Growth Hormone-Releasing Hormone Antagonist On Human Adipose-Derived Stem Cells, Jeanne Michelle Dugas

Master's Theses

Obesity is a condition that affects over 40% of American adults and contributes to numerous preventable health issues. This condition is caused by increased adipose tissue, which forms when stem cells transform into adipocytes. Mesenchymal stem cells, including human adipose-derived stem cells (hASC), are multipotent with the ability to differentiate into adipocytes, osteocytes, or chondrocytes. Many factors affect this transformation, including the peptide growth hormone-releasing hormone (GHRH). The main role of GHRH is to trigger the release of growth hormone, but it has also been found to play an important role in adipocyte metabolism. We expect that if the differentiation …

The Antioxidant Potential Of Rosemary Leaf-Derived Nanovesicles, Shani Akila Griffin

Master's Theses

Human dermal fibroblasts are essential for maintaining skin homeostasis. However, exposure to exogenous and endogenous stressors can lead to fibroblast instability, extracellular matrix degradation, and excessive reactive oxygen species (ROS) production. These factors contribute to skin aging and ROS-induced skin disorders leading to hair loss. Adverse effects from synthetic treatments have driven interest in natural alternatives like plant extracts for skin therapy. However, the polyphenols in these treatments require an effective delivery system to ensure their stability and targeted application. Plant derived nanovesicles (PDNVs) are emerging as a promising natural alternative for therapeutic applications. Their biocompatibility, stability, and encapsulated compounds …

"The Way It Comes—Through Nature:" Christian Realism, Rural Landscapes, And Divine Confrontations In Flannery O'Connor's Farm Fiction, Ashton Bailey Thomas

Master's Theses

Flannery O’Connor, though often labeled a Southern Gothic writer, preferred to place herself in the genre of “Christian Realism.” For her, the grotesque nature of her stories’ endings reflects not grace itself but the culmination of repeated rejections of grace. In her essays and letters, O’Connor argues that grace should be depicted “the way it comes—through nature,” equating the spiritual with the natural world. In her stories’ farm landscapes, O’Connor presents an ever-present grace through nature that, though often ignored or rejected, serves as a catalyst for spiritual confrontations. When this grace is continually denied, violence becomes the only force …

Gis And The 1944 U.S.–Mexico Treaty: Rethinking Transboundary Governance Under Climate And Demographic Stress, Pedro L. Sarabia

Master's Theses

This thesis examines the structural limitations of the 1944 U.S.–Mexico Water Treaty in the context of intensifying climate stress and growing population demand. Using GIS-based raster analysis of precipitation from 1981 to 2024, it maps hydrological trends in treaty-bound basins—particularly the Rio Grande and Lower Colorado—which exhibit persistently low and variable precipitation. These conditions, coupled with institutional rigidity, threaten the sustainability of binational water management. In addition to quantitative analysis, the study includes a qualitative assessment of transboundary governance dynamics, highlighting how institutional fragmentation and policy contention impede adaptive responses. The Treaty’s current surface-water-only framework excludes groundwater management, real-time data …

The findings reveal how homonationalist tendencies may manifest at the intersection of engagement metrics, identity-centric rhetoric, brand …

Climate Shocks, Crop Yields, And School Enrollment In Rural Ethiopia, Mallika Matharu

Master's Theses

This study investigates how climate-induced shocks to agricultural productivity affect school enrollment in rural Ethiopia. Using five waves of panel data from the Ethiopia Living Standards Measurement Study (LSMS) and satellite-derived weather indicators, I estimate the causal effects of crop yields, specifically Teff, Sorghum, and Maize, on children’s school attendance. To address the endogeneity of agricultural output, I instrument crop yields with agro-climatic measures such as growing degree days (GDD), harmful degree days (HDD), and soil moisture during the Meher growing season. The main empirical strategy uses a two-stage instrumental variable approach with region and wave fixed effects. Results suggest …

Loadshedding And Nighttime Light Intensity In South Africa: Evidence From High-Frequency Satellite Data, Jurney Lajos

Master's Theses

This paper investigates the relationship between loadshedding and nighttime light intensity in South Africa using high-frequency satellite data from 2020 to 2024. By linking rotational blackout schedules to daily radiance measurements at the suburb level, the study examines how electricity disruptions affect visible light emissions and whether these effects vary by wealth. Results show that while load shedding has be-come increasingly severe in recent years, its impact is not felt equally. Poorer suburbs experience larger and more persistent reductions in nighttime radiance during black-outs, suggesting limited capacity to adapt. In contrast, wealthier suburbs show signs of resilience, with smaller drops …

Flooding is a major cause of destruction and economic loss affecting over 80 million people annually. Flooding during childhood can lead to educational setbacks with long term economic impacts. This study investigates the causal impacts of flood shocks on educational achievement and children's time use using the Young Lives Survey, a panel dataset surveying children in Peru over 19 years of childhood. This study finds that flooding causes a temporary positive "spike" in girls hours of labor immediately after a flood which subsides by three to six years after flooding. The additional hours of labor does not reduce hours of …

Unequal Shocks: The Heterogeneous Impact Of Earthquakes, Claire Marie James

Master's Theses

What effect does neighborhood wealth have on disaster outcomes and disaster induced migration? Using the 2023 Kahramanmaraş Earthquake in Southern Türkiye and Syria as a natural shock, I examine how the short term migration response to building damage and earthquake exposure differs by average neighborhood home prices. Using a panel dataset of population by bing tile, from Meta’s Data for Good Project, I employ time series and cross sectional regression analysis. I find that wealthy neighborhoods are better able to retain population than non-wealthy counterparts.

Weather Impacts On Migration And Food Insecurity In Bangladesh, Brendon M. Wong, Andrew Hobbs

Master's Theses

This paper analyzes the impact of weather shocks on household migration and food insecurity, and the mechanisms in which they do so. As climate change continues to impact weather patterns, subsistence farmers remain extremely vulnerable and can experience decreases in welfare. Using the Bangladesh Integrated Household Survey, we construct a panel dataset to measure the effects of temperature and rainfall on remittance amounts, food consumption scores, and child wasting z-scores. We observe that weather has strong impacts on these outcomes but are dependent on the rice variety and growing season. We do not find strong evidence that the mechanism in …

The Prescribing Of Gender, A Scope On The Societal Ideologies Showcased Within Le Roman De Silence, Derrian Fernandez

Master's Theses

Culture is constantly evolving, its ideologies cementing themselves within our minds, shaping how we as a society guide ourselves through living in such. Social class, religion, gender, all are forms of identity that have a place, and a certain understanding and standing within our culture and society. Through this understanding of ourselves, we are defined, creating multiple forms of distinct expression to help differentiate our place further. A pope is expected to wear a certain attire just as a bride is expected to. The same ideology trickles down, creating demarcations of attire that subsequently ingrain themselves into our culture and …

Does Limb Specialization In Track And Field Introduce Asymmetry In Dynamic Stability?, Aaron X. Jones

Master's Theses

Time to stabilization (TTS) represents the time it takes for a person to become still after a hop landing. Lower times suggest greater dynamic stability. Whereas leg dominance (preference) does not seem to have a significant impact on TTS performance in the general healthy populations, limb specialization in sport may introduce asymmetry. This study compares TTS following forward hops in healthy male controls (N = 19) to varsity DIII Track & Field athletes (N = 20). Groups were equal for height, but the athlete group’s average limb length (106.7 ± 5.5 cm) was greater than the control group (101.5 ± …

A secondary goal was to describe habitat associated with G. …

Jump Strategy Changes In Collegiate Women Soccer Players, Madeline Klubertanz

Master's Theses

Countermovement jumps (CMJ) are often utilized to monitor athletes because of their sensitivity to neuromuscular fatigue, which can be seen through assessing jump strategies. The current literature has reported conflicting views on how jump performance is impacted over acute and longitudinal testing. This is likely due to insufficient analyses regarding the impact of fatigue on jump strategy. This study aimed to investigate how the integration of jump strategy metrics and single-subject analysis could provide a better representation of the presence of fatigue among collegiate women soccer players. Eighteen participants were utilized in this study. Participants were required to complete three …

Assessing The Effect Of Prolonged Saltwater Exposure On Dna Recovery In Submerged Skeletal Remains From Sus Scrofa Domesticus (Erxleben, 1777), Malia Wellens

Master's Theses

Both water-related and mass disasters occurring over or in water (e.g., boating disasters, commercial plane crashes, and natural disasters) result in multiple deaths every year. Due to the ocean's vastness and lack of equipment, remains may not be recovered for some time, resulting in soft tissue decomposition, leaving bone as the last repository of recoverable DNA for identification purposes. Skeletal remains' physical and chemical components protect them from environmental deterioration and biological attack and preserve DNA well. Therefore, identifying an individual may depend on DNA obtained from skeletal remains. However, there is limited research on how long DNA can be …
