I will dive into detail regarding my process, choices, and the piece’s narrative. I will describe the choreography process of the piece and the symbolism behind certain sections, …

Supplemental Feeding Alters Foraging Behaviors Of Tarantulas In Their Natural Habitat (Aphonopelma Hentzi), Annalyse Leach Brogan

Senior Honors Theses and Projects

Foraging success is a crucial factor in survival and reproductive success for many animals. One mechanism that can improve an organism’s foraging success is foraging plasticity, or the organism’s ability to alter their behavior in response to environmental changes. This study aims to evaluate if the Colorado Brown Tarantula, Aphonopelma hentzi, a long-lived, sit-andwait predator will use foraging plasticity in response to increased prey encounters. I predicted that tarantulas with more prey encounters will have a higher body condition index, shorter foraging duration, and shorter distances traveled from the burrows. I conducted a field study on A. hentzi in their …

From Dictatorship To Sectarianism: Iraq's Domestic Politics And Minority Rights (1979-2023), Hiba Alkhuzaee

Senior Honors Theses and Projects

This study looks at how Iraq’s domestic politics have changed, moving from Saddam Hussein’s authoritarian rule to the post-2003 era that’s been heavily shaped by sectarian divisions. It focuses on how Shi’a communities were systematically oppressed under Saddam’s Sunni-led Ba’athist regime and then compares that to the frustrations many Sunnis have faced under the mostly Shi’a-led government that came after the U.S. invasion. By looking at government policies, shifts in society, and the current status of minority rights, I explore how sectarianism has shaped governance, complicated the Kurdish issue, and affected things like inter-sect marriages between Shi’a and Sunni Muslims. …

The purpose of this literature review is to determine if nursing students feel adequately prepared to care for patients with substance use disorder, and how implementation of educational curricula can increase students' knowledge of caring for individuals with substance use disorder, leading to an increase in confidence when caring for …

Pilot Study: Development Of A Food Delay-Discounting Measure For Individuals With Neurodevelopmental Conditions, Aaron Daniel Schwieterman

Senior Honors Theses and Projects

Individuals with intellectual (NDD) and neurodevelopmental (NDD) conditions experience disproportionately higher rates of obesity (Hsieh et al., 2014; Ptomey et al., 2020). Yet their diet decision-making process has been left out of the current literature. Delay discounting, which reflects the decrease in the subjective value of a reward as the delay to its receipt increases, has been linked to obesity and unhealthy food intake in typically developing adults. However, most existing tasks rely on hypothetical rewards and verbal reasoning, which limit their use with individuals who have cognitive or communication differences. The present pilot study developed and evaluated a novel …

Fairness-Aware And Culturally Adaptive Machine Learning For Predicting Adolescent Substance Use, Stephanie Nworgu

Senior Honors Theses and Projects

Early initiation of substance use during adolescence poses significant risks to long-term health, educational attainment, and social outcomes, making early identification a critical public health priority. Machine learning models have increasingly been used to predict substance use risk; however, many such models do not explicitly examine whether predictive performance differs across demographic groups. This senior project examines the fairness of logistic regression models used to predict first-time alcohol use among adolescents. Using nationally representative survey data from the Youth Risk Behavior Surveillance System (YRBSS), pooled across the 2017, 2019, 2021, and 2023 survey cycles, this study develops logistic regression–based predictive …

Colorblind Racial Attitudes Mediates The Association Between The Internalization Of Model Minority Myth Attitudes And Tolerance, Talal Ali

Senior Honors Theses and Projects

The model minority myth is the belief that Asian Americans are generally more intelligent and more hardworking than other minority groups. Many studies have demonstrated the relationship between belief in the model minority myth and anti-Black sentiment in White Americans. However, there is little literature on the relationship between belief in the model minority myth and anti-Black sentiment in Asian Americans. With this in mind, we plan to determine whether the internalization of the model minority myth in Asian Americans has a relationship with anti- Black sentiment. This relationship is being measured by the IM-4 Scale (which measures the internalization …

The Impact Of Facility Dogs On College Students' Stress Management And Emotional Regulation, Anna Reichert

Senior Honors Theses and Projects

College is a demanding transitional time where students experience new friendships and personal growth. During this time, mental health issues can surface, which impact emotional well-being. Studies have shown that dogs reduce stress, anxiety and depression, encourage exercise, lower blood pressure, and raise oxytocin and dopamine levels (American Heart Association, 2021). Eastern Michigan University introduced their own facility dog, Tinker, a two-year-old golden retriever. Since Fall 2024, she has provided emotional comfort and relief to students and the campus community. Students were surveyed on stress levels and if and how Tinker made an impact. Survey results show Tinker’s effect on …

White Racial Identity, Climae Change, And Social Attitudes, Alyssa Engle

Senior Honors Theses and Projects

This study examined how symbolic racism, political conservativism, and White racial identity predicts attitudes toward climate change among White Americans. Prior research suggests that racial resentment vaticinates social and political judgments beyond explicitly racial domains, including environmental issues and policies which disproportionately harm Black and marginalized communities. Building on this prior research, the present study investigated whether racial identity dimensions predict climate change distress, and whether symbolic racism mediates associations between conservative political orientation and climate concern. Seventythree White undergraduate students completed measures of racial identity, symbolic racism, distrust in climate science, political conservatism, and climate distress. As predicted, a …

While these technologies offer efficiency and consistency, they also raise important questions related to bias, fairness, privacy, and the continued role of human judgment in hiring decisions. The purpose of this study is to examine how AI is currently used in staffing practices and how organizational leaders perceive its benefits and limitations. This study employed a qualitative research design using semi-structured interviews with three business owners and …

A Retrieval Augmented Approach To Improving Accuracy Of Biomedical Term Normalization By Large Language Models, Thanh Son Do

Graduate Theses/Dissertations

Ontology normalization is crucial in biomedical text processing, as it enables the mapping of medical expressions to standardized ontology terms and their corresponding identifiers. This thesis explores the feasibility of using large language models (LLMs) for ontology normalization, with a specific focus on the Human Phenotype Ontology and Gene Ontology. Prior research studies indicated that LLMs employing zero-shot learning tend to exhibit low accuracy and are prone to frequent hallucinations. We propose a retrieval augmented generation (RAG) approach to address these limitations and enhance normalization accuracy. We generated synthetic test sets of ontology-derived synonyms to evaluate normalization performance and developed …

Help Or Hindrance? Humans As A Range Expanding And Reducing Force For Himalayan Black Bears In Nepal, Suman Shree Neupane

Graduate Theses/Dissertations

I explore the relationship between Himalayan black bears (HBBs) and humans by constructing niche models for HBBs considering both natural and human influences. This approach allowed me to assess the net impact of human activities on HBBs, which face challenges like habitat fragmentation, but also reap some benefits (like increased food availability). I examined HBB niche impacts from humans by quantifying and comparing the extent of HBB niche space when including versus excluding anthropogenic influences. Specifically, I estimated the natural HBB niche space by assuming no human alterations of the landscape and compared this natural range to the observed range …

A Study Of Collegiate Equine Team Funding, Expenditures, And Recruitment Strategies, Sydni Marie Nilles

Graduate Theses/Dissertations

Collegiate equine teams (including horse judging, equestrian, ranch horse teams) have been recognized for their contributions to students' personal and professional development for post- graduation success. Teams have been used to provide opportunities, a sense of belonging and allow for experiences students may not have elsewhere. However, there is a notable gap in knowledge as to where funding comes from and how much teams may be able to budget for expenditures. Recruitment tactical knowledge provides other teams with knowledge of potential areas they may be lacking or unaware of. I used an online survey to understand current ranges of support …

Relational Density Theory And Intercultural Interaction: Identifying And Shifting Perceptions Of At-Risk Groups, Ryan T. Moser

Graduate Theses/Dissertations

Intercultural interaction is an important aspect for fostering global engagement and competence, yet we find that despite the numerous opportunities, many don’t engage cross-culturally. The current paper utilizes Relational Density Theory (RDT; Belisle & Dixon, 2020a) to examine and modify perceptions of approachability through two experiments. In experiment 1, a Multidimensional Scaling Procedure (MDS) was utilized to identify at-risk groups for non interaction among college students as well as willingness to engage. In experiment 2, a Stimulus Pairing Observation Procedure (SPOP) was utilized to determine whether exposure to positively valanced stimuli could shift the perceptions of the at-risk groups to …

The Effects Of Corporal Punishment In Childhood On Early Adulthood Cortisol And Aggression, Tyler Priest

Graduate Theses/Dissertations

The current study aimed to see if experiencing corporal punishment led to more aggressive behaviors as well as higher cortisol levels than in those who did not experience corporal punishment. The study also examined whether self-regulation moderated the relationship between corporal punishment and levels of aggression. Morning cortisol levels were collected from participants, and they completed a demographics survey, an aggression index, a corporal punishment index, and a self-regulatory inventory index. A T-test found that there was not a significant difference in morning cortisol levels between those that experienced corporal punishment and those that had not experienced corporal punishment. A …

Effects Of Liraglutide On The Gut Bacterial Community, Jami Anne Bull

Graduate Theses/Dissertations

Overweight and obesity are major health concerns associated with metabolic disorders and gut dysbiosis. Treatment options such as GLP-1 receptor agonists, like liraglutide, promote weight loss and improve insulin sensitivity; however, their impact on the gut bacterial community remains unclear. This study investigated the effects of liraglutide on the gut bacterial community of diet-induced obese (DIO) mice using Illumina DNA sequencing of the bacterial 16S rRNA gene. My study used twelve-week-old male C57BL/6J DIO mice. They were placed on a high-fat diet and treated with liraglutide (0.2 mg/kg) via daily subcutaneous injection for 14 Days. High-fat and low-fat diets control …

Cyber Warfare And The Future Of Conflict, Victor A. Mercado

Graduate Theses/Dissertations

This thesis examines whether cyber warfare now poses a more immediate threat to U.S. national security than weapons of mass destruction (WMD). Cyber operations have become a dominant instrument of contemporary conflict, with malicious actors operating in a persistent “grey zone” that blurs traditional boundaries between war and peace. These operations target military and civilian entities, both directly and often as collateral damage due to the uncontrollable nature of cyber threats. WMDs, despite their catastrophic destructive potential, remain largely constrained by established deterrence frameworks.

The evolving nature of cyber warfare warrants comparison to WMD effects and impact, as cyber capabilities …

Learned Helplessness: An Online Replication And Validation, Arshpreet (Sunny) Kandola

Graduate Theses/Dissertations

The current study entails the partial replication of a classic learned helplessness two-phase triadic design experiment within an online learning context and aimed to validate a new attributional style self-report measure designed to identify individual differences in tendencies to develop learned helplessness consistent with the original reformulation of the hypothesis. Further, recent innovations in neuroscientific technology have allowed for a deeper examination of the mechanisms at play, finding support for a major re-interpretation of the theory of learned helplessness - suggesting that helplessness is more so the default passive response, while the active ingredient that is detected or expected (i.e., …

Investigating Social Attenuation Of The Stress Response In Juvenile Northern Cottonmouths (Agkistrodon Piscivorus), Alyssa Owens

Graduate Theses/Dissertations

When social organisms encounter a stress-inducing event, the presence of a conspecific can dampen the physiological and/or behavioral response elicited by the stressor. This concept, termed ‘social buffering’, has been well documented in mammals, but there are few studies investigating this phenomenon in organisms traditionally perceived as asocial, including reptiles. However, the paradigm is shifting, and social behavior is now more widely recognized in reptiles, including snakes. In this study I tested whether juvenile Northern Cottonmouths (Agkistrodon piscivorous) experience social buffering by measuring changes in heart rate in snakes following an acute stressor with and without the presence …

Fostering Effective Practice: Using Metacognition Logs In The Private Voice Studio, Colleen C. Pingel

Graduate Theses/Dissertations

ABSTRACT

The purpose of this case study was to examine the short-term impact of metacognition instruction on the practice of a single voice student in a private studio. Across four lessons, the student received explicit instruction in metacognitive strategies and applied them through guided practice logs supporting planning, monitoring, adjusting, and reflecting. Each lesson began with a review and discussion of the practice logs. The teacher-researcher recorded these discussions to capture the student’s thinking and maintained a journal to document observations, instructional decisions, and reflections. Data analysis involved primarily qualitative methods focused on reflections, discussions, and practice logs. Quantitative measures, …

Effects Of Climate Change On Fungal Diversity And Function In Streams, Syeda Tasfia Imam

Masters Theses

"This study investigated the impact of climate change, particularly drought, on leaf decomposition and associated fungal and macroinvertebrate communities in freshwater ecosystems. With climate change, streams may experience altered hydrology, leading to shifts in community composition and biogeochemical processes. Fungi decompose organic matter, facilitate nutrient cycling, and support food webs. However, drought can disrupt these processes by reducing water availability, causing declines in fungal diversity and activity. I examined leaf breakdown and associated biota in 13 stream sites across varying hydrologic conditions, from perennial to ephemeral flow patterns. Flow duration varied during the 8-week study. Leaf breakdown was significantly related …
