Designing Enhanced Nonlinearity In Plasmonic Devices With Epsilon-Near-Zero Films, Kevin Tran Le

Electrical Engineering and Computer Science (MS) Theses

The growing demand for energy-efficient optical information processing motivates compact nonlinear photonic devices that can operate at low power. Silicon photonics is a mature platform for linear optical functions, but nonlinear operation remains challenging because of its weak Kerr response, two-photon absorption at telecommunication wavelengths, and limited compatibility with deeply subwavelength plasmonic confinement. This thesis computationally investigates epsilon-near-zero thin films integrated into plasmonic waveguide architectures as a route toward stronger light–matter interaction in compact nonlinear devices.

Two waveguide geometries are examined: a hybrid metal-insulator-metal plasmonic slab waveguide incorporating an ultrathin indium tin oxide epsilon-near-zero layer (5–50 nm), and a dielectric-loaded …

Exploring The Quality-Of-Life Impact Of Driving For People With Aphasia, Kaleigh Welch, Emily Huddleston

Appalachian Student Healthcare Research Review

Purpose: This study explored how driving ability or loss affects the social, emotional, and practical quality of life of people with aphasia (PWA). Given that driving is a key marker of independence, identity, and community participation, the study aimed to understand how individuals with aphasia experience driving resumption or cessation and how these experiences shape daily functioning and psychosocial well‑being.

Methods: Semi-structured interviews were conducted with seven adults with aphasia recruited from a university-based aphasia group. Interviews were completed in a private university clinic room. Open-ended questions elicited participants’ feelings, experiences, and perceptions regarding driving or not driving after aphasia. …

A Multi-Objective Optimization Framework For Equitable Stormwater Management In Urbanizing Rural Communities, Harry L. Wilson

Industrial Engineering Undergraduate Honors Theses

Due to limited technical and financial resources, urbanizing rural communities often face growing stormwater management challenges while undergoing rapid development. This thesis proposes a mixed-integer linear programming (MILP) framework that integrates topography-driven stormwater flow behavior, infrastructure placement constraints, and multiple planning objectives to support cost-effective stormwater infrastructure decisions. Our model accounts for budget constraints, gravity-driven surface water flow, infiltration capacity, and spatial contiguity requirements to determine optimal pond placements that balance flood reduction and implementation costs. A synthetic discretized grid representing a small municipality is used to demonstrate model behavior under varying rainfall and topographic conditions. Results demonstrate the framework's …

The Impacts Of High Protein Diet On Sleep And Mood In Women With Polycystic Ovary Syndrome (Pcos), Lily G. Hiegel

Biological Sciences Undergraduate Honors Theses

The objective of this study is to determine whether adherence to a high protein diet over a sixteen-week period leads to improvements in sleep quality and mood in women with PCOS. It is hypothesized that individuals following the high protein diet will demonstrate significantly better sleep quality and more favorable mood profiles compared to individuals not following the high protein diet. By targeting insulin resistance and dietary carbohydrate intake, this intervention may influence multiple pathways involved in PCOS symptomatology, including hormonal regulation, metabolic function, sleep physiology, and psychological wellbeing.

The Association Of Birth Order And Coping Strategies In Children During Family Stress; A Case Study On A Second-Born Child, Jaymee Bass

Theses & ETDs

This study examined the association between birth order and coping strategies in children, with a particular focus on primary and secondary control coping during family stress. Drawing on theoretical models of coping that distinguish between efforts to change external stressors (primary control) and efforts to adapt internal responses (secondary control), the study explored whether children’s roles within the family may help predict their preferred coping mechanisms. Prior research suggests that personality traits, sibling dynamics, and family structure influence both emotional development and coping processes, indicating that birth order may be a meaningful factor in how children respond to stress. Participants …

Scenic Design: Adapting Psychological Horror From Film To The Stage, Natalie Welch

Theses & ETDs

This thesis has the goal of creating a scenic model for a new theatrical adaptation of an already existing psychological horror film. To help achieve this, it discusses psychological horror and how sets can create the desired effects of the genre. The thesis is split into two chapters. The first chapter is research-based and goes into psychological horror in both film and theatre. The mediums are looked at individually and then compared through the play and film versions of The Innocents and The Woman in Black. At the end of this chapter, I go into more detail about the practical …

Gendered Socialization Of Comfort With Risk And The Selection Of A College Major, Eliza S. Staton

Sociology and Criminology Undergraduate Honors Theses

This study investigates the potential relationship between the gendered socialization of risk preferences and the selection of a college major. Women are underrepresented in many fields of study, but especially in those related to science, technology, engineering, and math (S.T.E.M). Careers in STEM fields tend to require degree paths that require difficult classes, with lower average grade points, and a high chance of failure. As of 2023, only 24% of the student body in the College of Engineering at the University of Arkansas was composed of women (Uark 2023). These high-pressure, male-dominated environments have been found to lose women at …

Sustaining Care In The Nonprofit Sector: A Qualitative Study On Burnout, Secondary Trauma, And Compassion Fatigue, Anna Kate Kelly, Alexia Angton Phd

Sociology and Criminology Undergraduate Honors Theses

Given the high emotional toll of nonprofit work, burnout, secondary trauma, and compassion fatigue are prevalent among employees. This study examines how these phenomena manifest in individuals' everyday lives. Drawing on in-depth interviews with eleven nonprofit workers in the South-Central United States, the findings reveal three primary themes: the consequences of emotional labor, frustration with the system, and supportive strategies. Overall, participants described a tension between finding deep purpose and meaning in their work and experiencing an emotional burden that shapes how they engage with the world. These findings have implications for mental health care, organizational practices, advocacy and policy, …

All artworks are included in a curated exhibition, and the development of the gallery display is also documented. The central work combines physical and digital spaces through the use of modern technology, the classic illusion of Pepper’s ghost, and a miniature room environment. With …

Perceptions Of German Eugenics: An Analysis Of German Eugenics In The Eugenics Review, 1920-1945, Ally Iandolo

Political Science Undergraduate Honors Theses

This research examines how the eugenics movement in Germany was perceived by academic peers. I utilize entries from the British journal, The Eugenics Review, from 1920-1945 to create a database of all journal articles, book reviews, correspondence, and other entries that mention German eugenics. Then, using this database, I determine how German eugenics was perceived and which topics were identified by the journal’s contributors. Further, I analyze the careers of the authors who wrote these articles to understand the scope of interest in German eugenics from the Eugenics Review.

Avoiding Anchoring Bias In Lymphadenopathy: Metastatic Thyroid Cancer Mimicking Tuberculous Lymphadenitis, Giuliano Romano, Mitchell Schwocho, Jacob Morton

Sequential Robustness In Adversarial Reinforcement Learning, Roman Lok-Ming Belaire

Dissertations and Theses Collection (Open Access)

My goal is to build autonomous systems that expand the reach of human capability in challenging domains such as undersea and space exploration, disaster response, and large-scale infrastructure. In everyday settings, these systems will increasingly appear in safety-critical applications such as autonomous driving, robotics, and industrial manufacturing. A central requirement for these systems is the ability to operate reliably under uncertainty, particularly when the environment behaves in unanticipated ways.

The robust handling of unforeseen environment dynamics is therefore a technical cornerstone of autonomous decision-making; Adversarial attacks provide a useful and principled lens through which to study this problem. Adversarial \textit{robustness}, …

Perspectives On Interpretability For Neural Text Representations, Jia Peng Lim

Dissertations and Theses Collection (Open Access)

In this dissertation, we investigate interpretability in the three elements of learning neural text representations: inputs, passed into models, to produce probabilistic outputs. We emphasise perspectives as we present alternative novel methods to mine and organise meaning in this work.

Models. We initiate our investigation by examining Neural Topic Models (NTM), proposing an alternate angle of interpreting its word-topic distribution, producing better topic representations for interpretation. Our method maps the problem of finding these better interpretations to classical NP-hard graph problems, enabling examination of topic distributions in a composite manner. Next, we apply our previous findings to extract interpretations from …

Exam Approach Impacts On Test Anxiety And Motivational Outcomes, Makenna Lynn Frias

Undergraduate Honors Thesis Collection

In science, technology, engineering, and math (STEM) fields students are facing exams with record high rates of worry and discomfort, this is known as test anxiety (Rajiah, et al., 2014). Factors such as self-concept (Simpkins et al., 2006) and views of control (Levenson, 1974) are negatively affected by examinations (the terms ‘exam’ and ‘test’ will be used interchangeably) (Spielberger, 1980). A student’s fear of failure, or how the students perceive setbacks or challenges, impacts and is impacted by test anxiety (Henry et al., 2021; Conroy, et al., 2002). Being established by the professor, the exam approach is beyond a student’s …

Applications Of Cyrene For Pharmaceutical Synthesis, Anjali Mae Rabindran

Undergraduate Honors Thesis Collection

Cyrene is a cellulose-derived molecule that has gained interest in green chemistry as both a solvent and precursor for pharmaceutical intermediates. In this study, biocatalytic and chemical strategies were evaluated for converting Cyrene into these intermediates. Cyrene was carried through variations of a five-step sequence: reduction, reductive amination, esterification, tosylate salt formation, and Lewis-acid mediated acetal opening to generate ring-opened pyranose products (“deoxy sugars” and “deoxy amino sugars”). We successfully synthesized deoxy sugar intermediates; however, the production of stereochemically pure deoxy amino sugar intermediates was limited by unresolved diastereomeric mixtures. These findings highlight the promise of Cyrene as a renewable …

Patterns Of Acquisition For /ɹ/ Across Phonetic Contexts, Hailey Nielson

All Graduate Reports and Creative Projects, Fall 2023 to Present

Purpose: 

This study examined longitudinal changes in /ɹ/ production (i.e., the “r” sound) among 14 children aged five to seven at risk for persistent speech sound disorders (SSDs). Children at risk for SSDs show slower or atypical development of /ɹ/, yet little is known about which early patterns predict persistent difficulty, making it difficult for clinicians to prioritize caseloads and provide timely intervention. Using perceptual accuracy ratings across varied /ɹ/ contexts, we modeled growth in /ɹ/ accuracy across different word contexts and evaluated the extent to which early accuracy and changes in /ɹ/production predicted mastery at age seven.

Methods: 

Longitudinal …

Implementation Of Udl In Secondary Classrooms: A Capstone Project, Livia J. Mortensen

All Graduate Reports and Creative Projects, Fall 2023 to Present

In today’s classrooms, students come from various backgrounds and may benefit from a variety of instructional approaches to meet their unique learning needs. Regardless of the need to tailor instruction for students, traditional teaching methods continue in classrooms but often fail to accommodate all the needs of our students. Many students, including students with disabilities, may struggle to engage with the standard curriculum that does not provide sufficient flexibility in instruction to reach all types of learners (Smith, 2012). Universal Design for Learning (UDL) is an educational framework that seeks to address this specific issue by promoting inclusive teaching practices, …

Which Energy Expenditure Equation Is Most Accurate In A Field-Based Setting?, Merrill C. Ward

All Graduate Reports and Creative Projects, Fall 2023 to Present

Several energy expenditure prediction equations for walking on varied terrain exist; however, these predictions are often theoretical and have not undergone rigorous field testing for accuracy. Field research on this topic is sparse. The aim of this study was to determine if any existing energy expenditure prediction equations are accurate in a field-based setting with load and gradient being taken into account (i.e., under conditions that are most applicable to day hiking). This was done by directly measuring relative VO₂ (ml/kg/min) of study participants and comparing these direct measurements to the values generated from the existing prediction equations. Fifteen …

Sql Query Optimization - Human Vs. Chatgpt, Hailey Dennis

All Graduate Reports and Creative Projects, Fall 2023 to Present

Large Language Models (LLMs) such as ChatGPT have become ubiquitous tools for working professionals in the software industry. Many engineers are finding new ways to increase productivity by offloading tasks onto LLMs, while others are finding it difficult to trust code produced artificially, even after review. Taking a look at both perspectives, this study aims to compare a human’s ability to optimize SQL queries to that of an LLM and assess the experience using both methods.

Manual query optimization is a tedious task that relies heavily on statistics, heuristics, and good intuition. The SQL developer must search for the optimal …

Check-In/Check-Out Implementation Across Grade Levels For Improving Unexcused Absences In A High School Setting, Otis C. Bitsuie

All Graduate Reports and Creative Projects, Fall 2023 to Present

Chronic absenteeism may contribute to declining graduation rates for many students with disabilities. Students with disabilities face challenges with academic and emotional behaviors. Chronic absenteeism causes students to fall behind with classroom materials, and they are unable to utilize instructional supports, emotional supports, or assistance with transitions. Students with disabilities who miss class often tend to drop out of school, which leads to difficulties with navigating post-high school life. Students who do not obtain a school diploma often experience high unemployment rates, homelessness, and incarceration. Students facing chronic absenteeism need interventions that will improve problem behaviors amongst students. I will …

Open Space Management Planning: A Framework And Case Study From Eagle Mountain City, Utah, Nathan K. Shumway

All Graduate Reports and Creative Projects, Fall 2023 to Present

Open Space Management Plans (OSMPs) are increasingly used by municipalities to guide the long-term stewardship of natural lands; however, little formal guidance exists regarding how these plans are structured, developed, or organized in practice. While numerous OSMPs are publicly available, their compositional logic, procedural workflows, and thematic priorities remain largely undocumented within academic literature. This study addresses that gap through a qualitative document analysis of fifteen publicly accessible OSMPs from the western United States, published between 2015 and 2024.

Using manual matrix-based coding in Microsoft Excel, each plan was analyzed through three lenses: structural composition, procedural development, and thematic content. …

Seasonal Body Composition And Neuromuscular Changes In High School Wrestlers: Medicine Balls For Fatigue Testing, Courtney Mccall Condie Carroll

All Graduate Reports and Creative Projects, Fall 2023 to Present

This study examines the effects a single wrestling season has on high school athletes’ body composition, muscle quality, membrane capacitance, and neuromuscular performance, and whether instrumented medicine balls are sensitive enough to serve as a field test for chronic fatigue. Twenty-five high school wrestlers (males=18, females=7) were recruited and assessed pre-season (Pre), mid-season (Mid), and end-of-season (Post). Outcome measures included body mass, fat-free mass, fat mass (via bioelectrical impedance spectroscopy), echo intensity (EI, via B-mode ultrasound) of the vastus lateralis (VL) and biceps brachii (BB), and countermovement rotational and backward-overhead throws with medicine balls instrumented with accelerometers.  Repeated measures ANOVA …

In This World: A Scalable Methodology For Scenic Design, Michael W. D. Francis

All Graduate Reports and Creative Projects, Fall 2023 to Present

This thesis examines how strong scenic design emerges not from how something looks, but from a clear understanding of how its world works. Rather than starting from aesthetic preference or visual trends, it outlines a process that identifies a central idea within a story and uses that idea to shape a cohesive spatial environment. By focusing on how a world behaves - what drives it, what resists change, and how its internal logic operates - design decisions begin to align, creating work that feels intentional rather than assembled. Through a series of production case studies, it evaluates how that process …

Uncanniness In Toni Morrison's The Bluest Eye, Seth L. Callor

All Graduate Reports and Creative Projects, Fall 2023 to Present

This thesis explores how Toni Morrison’s 1970 novel The Bluest Eye has a feature called the uncanny. Uncanniness, as originally explained by Sigmund Freud, is when something that was familiar becomes unsettlingly unfamiliar in a way that was likely once repressed. Other thinkers have since talked about how the uncanny is used in stories to question how their demographics are oppressed. Following their example, this thesis explains how The Bluest Eye is an example of using the uncanny to question harmful ways of seeing. Through demonstrating how The Bluest Eye uses obviously uncanny things like dolls and moves to more …

Together, the workbooks will help couples improve communication and implement healthy communication behaviors regarding …

“Women Vs. Perfection:” A Pentadic Analysis Of Toxicity In Online Gaming, Niyayesh Arshadnia

All Graduate Reports and Creative Projects, Fall 2023 to Present

This thesis utilizes a mixed-methods approach to examine an online video game player community as a case study to diagnose the underlying reason for widespread hostile behavior, especially towards women, among players in the online gaming sphere. The application of dramatism, a rhetorical theory that breaks down human behavior into elements of drama, reveals that the gaming industry and gaming culture are the likely perpetuators of this issue due to the environments they create and the behaviors they reward. This project is a diagnostic step towards rhetorically alleviating the exclusionary attitude of users in online gaming spaces through further research.
