The following research questions guided the study: (1) To what extent do the three basic psychological needs defined in SDT (autonomy, competence, and relatedness) mediate the relationship between the frequency of AI use and students’ levels of motivation (on the self-determination continuum) or resilience in an …

A Data-Driven Nutrient Density Scoring Framework For Beef Using Principal Component Analysis, Teja Vuppala

All Graduate Theses and Dissertations, Fall 2023 to Present

Beef is one of the most nutrient-rich foods in the human diet, providing high-quality protein, iron, omega-3 fatty acids, B vitamins, and a wide range of other compounds important to health. However, current nutrition scoring systems used on food labels were designed to compare different foods to one another — for example, beef versus broccoli — and do not work well for judging the nutritional quality of different beef samples relative to each other. A grass-fed steak and a conventionally-finished steak can carry nearly identical Nutrition Facts panels while differing substantially in their content of omega-3 fatty acids, vitamins, and …

Gender And Bill Changes In Congress: An Analysis Of Women-Sponsored And Women's Issue Bills, Kipling B. Corry

All Graduate Theses and Dissertations, Fall 2023 to Present

Women have faced historical disadvantages in American politics, generally, and in their positions as lawmakers. Bills in Congress, proposed by men and women alike, often undergo various textual changes before becoming law. This thesis explores how the gender of lawmakers and the gendered issues found within bills affect these changes. Are bills that are proposed by women disproportionately altered more than bills proposed by men? And are bills that concern women’s policy issues disproportionately altered more than bills that do not? This thesis investigates these questions by first presenting two original datasets and a full bill text file that introduce …

Cadmium Biosorption By Fusarium Venenatum And Its Application In Functional Permeable Materials For Metal Removal, Bradley Lawson

All Graduate Theses and Dissertations, Fall 2023 to Present

Heavy metals are pollutants of increasing concern as continued industrialization and urbanization have escalated the discharge of these toxins into aquatic environments. Cadmium (Cd) is a metal of particular concern due to its acute toxicity and high mobility in aquatic ecosystems. Given these characteristics Cd poses significant health risks to both humans and aquatic ecosystems. The continued development of sustainable, low-cost remediation technology is imperative to manage metal pollution.

This research explores the use of fungal-based remediation systems to remove Cd from contaminated water. Living biomass of the filamentous fungus Fusarium venenatum was evaluated as a biosorbent material for Cd …

Nutrient Leaching Under Traditional And Intercropped Cover Crop Fields In Northern Utah, Katherine Hewitt

All Graduate Theses and Dissertations, Fall 2023 to Present

This study examines whether cover crops can be used in Utah and the Intermountain West to improve water quality and reduce contamination due to nutrient leaching from agricultural soils into the groundwater. Cover crops such as grasses, clover, and other seed mixtures can be planted to improve soil health, increasing the soil’s ability to retain water and nutrients, which reduces the amount of nitrate and phosphate fertilizers lost through leaching and contamination. In Utah, short growing seasons and limited irrigation water availability hinder the ability to establish cover crops. By planting the cover crop between the rows (intercropping) when the …

Microbes In Pollination Systems: Effects On Pollinator Health, Floral Traits, Nectar Robbing, And Plant Fitness, Valerie Nicole Martin

All Graduate Theses and Dissertations, Fall 2023 to Present

Flowers produce nectar to attract pollinators, but nectar is also a habitat for yeasts and bacteria that arrive via pollinators, robbers, and other visitors. These microbes consume nectar sugars and release byproducts that change the smell and taste of nectar. Whether these changes affect how pollinators find and choose flowers, and whether they ultimately affect how many seeds a plant produces, is not well understood. In this dissertation, I studied how a common nectar yeast and a plant-associated bacterium affect the scent of wildflowers, the behavior of bumble bees and hummingbirds, and plant reproduction in montane meadows in central Colorado. …

Integrative Taxonomic Analysis Of Cryptic Species Diversity In The Spiny Witch-Hazel Gall Aphid, Hamamelistes Spinosus (Hemiptera: Aphididae: Hormaphidini) In Eastern North America, Gavin Andrew Powell Munson

All Graduate Theses and Dissertations, Fall 2023 to Present

Taxonomy is the practice of identifying, classifying and categorizing species, providing structure for the vast diversity of life. Aphids are an ecologically important group of soft-bodied insects, but they can be difficult to identify because of their tiny anatomical size, reduced or simplified morphological features, and morphological variation within a single species across different generations. In this study, the taxonomy of the spiny witch-hazel gall aphid, Hamamelistes spinosus, is revised. The complex multi-generational life cycle of the aphids, which alternates between witch-hazel and birch trees, has led to confusion regarding past descriptions. Scientists in the late 1800s who were …

Glioma Segmentation In Mri Using A 3d Hybrid U-Net With Adaptive Self-Attention And Multi-Modal Fusion, Evan P. Savaria

Computer Science Theses & Dissertations

Accurate glioma segmentation from multi-modal Magnetic Resonance Imaging (MRI) is essential for diagnosis, treatment planning, surgical guidance, radiation targeting, and longitudinal monitoring. MRI modalities such as T1, T1Gd, T2, and FLAIR provide complementary information for identifying clinically important tumor sub-regions, including enhancing tumor (ET), tumor core (TC), and whole tumor (WT). However, many existing segmentation methods do not fully preserve modality-specific information, process all modalities and slices uniformly, and often rely on a single shared fusion strategy for all sub-regions. These limitations can reduce segmentation accuracy, increase computational cost, and limit clinical interpretability.

This dissertation addresses these challenges through three …

The Role Of Phenotypic Plasticity And Bet-Hedging In Coping With Unpredictable Temperature Fluctuations In The Marine Annelid Ophryotrocha Labronica, Gabrielle Dawn Newton

Biological Sciences Theses & Dissertations

Coastal ecosystems are increasingly exposed to unpredictable temperature fluctuations, potentially favoring strategies that buffer populations against environmental uncertainty. This study examines how phenotypic plasticity and diversified bet-hedging contribute to variation in life-history traits under differing thermal predictability in the marine annelid Ophryotrocha labronica. After three generations at 24 °C, broods were reared for three generations under four thermal regimes: constant 24 °C (C24), constant 27 °C (C27), predictable fluctuations (Fp), and unpredictable fluctuations (Fu). Survival was assessed before and after acclimation to evaluate selective pressure among regimes. Age at maturity, fecundity, and growth rate were used to quantify plasticity (trait …

The Effects Of Working With Unidentified Migrant Remains: Caregiving, Border Security, And Human Rights On The U.S.–Mexico Border, Jennifer Delaine Huddleston

Graduate Program in International Studies Theses & Dissertations

This dissertation explores how migrant death and the handling of unidentified remains operate within U.S. border governance, focusing on caregivers, forensic anthropologists, and volunteer search-and-recovery teams who recover, document, and try to identify the dead along the U.S.–Mexico border. Using classic grounded theory and reflexive visual ethnography, the study includes interviews, field observations, and documentary photography conducted in South Texas, covering Brooks, Maverick, and Webb Counties.

Instead of viewing migrant deaths as accidental humanitarian tragedies, this dissertation situates caregivers’ daily work within a historical trajectory of deterrence-based border policies, from Prevention Through Deterrence to modern state-led enforcement regimes. It demonstrates …

Menopausal Symptoms, Psychosocial Factors, And Physical Activity Among Physically Active Midlife Females, Ella Onsoriasl

Exercise Science Theses & Dissertations

Menopausal symptoms are common during midlife and may be associated with females' physical activity (PA) participation, yet how these symptoms relate to PA levels, perceived confidence and enjoyment, and psychosocial resources such as social support (SS), exercise identity, and quality of life (QOL) remains unclear. The purpose of this study was to examine how menopausal symptom severity relates to PA levels, perceived confidence and enjoyment during PA, and psychosocial factors, including SS, exercise identity, and QOL. This cross-sectional study surveyed 151 midlife females aged 40 to 60 who reported engaging in intentional PA at least once per week. Participants completed …

The Mediating Role Of Hope In The Relationship Between Everyday Discrimination And Depression Among College Students, Busra Vurkun

Counseling & Human Services Theses & Dissertations

Research shows that marginalized populations experience disproportionately higher psychological distress (Budhwani et al., 2015; Bailey et al., 2019). Everyday discrimination, defined as chronic interpersonal mistreatment such as microaggressions and disrespect, is associated with greater depression and lower psychological well-being (Essed, 1991; Calabrese et al., 2015). Although the negative effects of discrimination are well established, less is known about protective factors that may reduce these outcomes. One such factor is hope, conceptualized by Snyder et al. (1991) as agency thinking and pathways thinking and linked to lower depression and greater resilience (Arnau et al., 2007; Banks et al., 2008). This study …

Autistic Students' Experiences With Hybrid Flexible Instruction In Higher Education: An Interpretive Phenomenological Study, Tracey Nicole Barr

STEMPS Theses & Dissertations

During the twenty-first century, autistic learners have enrolled in colleges and universities in greater numbers; however, the majority of research focused on their experiences in higher education has found them to be less academically successful than their neurotypical peers. The academic skills that autistic students bring to higher education are often tempered by social, emotional, and self-regulative challenges. The body of research focusing on autistic learners’ experiences in higher education is currently limited and focused primarily on fully in-person and online course models. No extant research has focused on autistic students’ experiences with hybrid or blended course models.

This interpretive …

Strategies Black Male Students With Social Anxiety Use To Persist And Succeed At Rural Community Colleges, Gwendolyn F. Houston

Educational Leadership & Workforce Development Theses & Dissertations

Social anxiety, one of the more common types of anxiety, has been linked to poor concentration, impaired performance, and lower academic achievement (BlackDeer et al., 2021; Derakshan & Eysenck, 2009; Leigh et al., 2021). This study addresses the questions: “How do Black male students with social anxiety at rural community colleges in the Southeastern United States handle both academic and non-academic challenges and cope with these stressors?” and “How do Black male students with social anxiety navigate barriers during their journey at rural community colleges in the Southeastern United States, and what strategies do they use to manage these obstacles?” …

Modeling And Generating Crash Avoidance Behaviors In Safety-Critical Vehicle–Pedestrian Interactions Using Deep Reinforcement Learning, Qingwen Pu

Civil & Environmental Engineering Theses & Dissertations

Traffic crashes between vehicles and pedestrians arise from complex, split-second interactions in which both parties make rapid evasive decisions. Four fundamental gaps persist in existing research. Surrogate safety measures assume linear trajectories, failing to capture the curved movements of turning vehicles and crossing pedestrians at intersections. Single-agent modeling treats one party as a fixed obstacle, ignoring the joint decision-making that governs near-miss outcomes. The effect of vehicle type on pedestrian avoidance behavior—whether pedestrians respond differently to automated vehicles (AVs) than to human-driven vehicles (HDVs)—remains poorly understood. Finally, automated driving system development is hampered by a severe scarcity of large-scale, behaviorally …

De Facto Captivity In The Land Of The Free: Exploring The Confining Effects Of Network And System Avoidance, Brianna Ovalle

Sociology & Criminal Justice Theses & Dissertations

Encroaching state surveillance has primarily targeted people of color living in urban, inner cities, resulting in both much higher likelihoods of encountering state agents and the consequences of such contact. The ceaseless surveillance has led some individuals to engage in protective behaviors aimed at minimizing encounters with agents of the CLS. These behaviors are adaptable to present risks of surveillance and contact with the system. While there are various types of avoidance, the focus of this research is system avoidance and network avoidance. Previous literature for both types of avoidance focuses on the experiences of lower SES men. Further, as …

Time-Frequency Analysis Of Arterial Pulse Signals Of Cardiovascular Disease Patients Measured By A Microfluidic-Based Tactile Sensor, Md Mahfuzur Rahman

Mechanical & Aerospace Engineering Theses & Dissertations

This dissertation presents a single-degree-of-freedom (SDOF) based time–frequency analysis framework that can simultaneously extract a comprehensive set of cardiovascular autonomic indices from arterial pulse wave recordings obtained at rest and post-exercise, supporting non-invasive monitoring of autonomic recovery during cardiac rehabilitation. The framework rests on three technical contributions.

First, an SDOF analytical model of motion artefacts quantifies two physically distinct distortion mechanisms: additive baseline drift and Time-Varying System Parameter (TVSP) generated distortion of the Tissue-Contact-Sensor (TCS) stack. Baseline drift is slowly varying and removable by filtering; TVSP distortion rides on all harmonics of the true pulse signal and cannot be removed …

Deep Multimodal Sensor Fusion For Autonomous Driving: A Real-World Deployment On Little Blue, Raphael T. Pamie-George

Electrical & Computer Engineering Theses & Dissertations

Accurate perception and control systems are essential for autonomous vehicles to safely interpret and navigate complex environments. Individual sensing modalities such as cameras, LiDAR, and inertial measurement units (IMUs) provide valuable environmental and vehicle state information; however, each sensor exhibits inherent limitations when used independently. Camera performance can degrade under varying lighting conditions, LiDAR measurements may be sparse or affected by environmental noise, and IMU measurements are susceptible to drift over time. Little Blue, a research autonomous vehicle platform from ODU (Old Dominion University), previously relied primarily on camera-based data for neural network training, limiting the system’s ability to exploit …

The Rending Of The Temple Curtain In The Gospel Of Luke: Its Relocation And Implications, Kim Kai Chan

Electronic Theses and Dissertations

The rending of the temple curtain at Jesus’s death is recorded in all three Synoptic Gospels, yet Luke relocates the event from after to before Jesus’s death, creating interpretive challenges. While Mark connects the curtain’s tearing to the rending of the heavens at Jesus’s baptism through the verb σχίζω, this study argues that Luke reframes the tearing motif by linking the curtain’s rending to the tearing of the new garment in the parables of Luke 5:36–39, likewise employing σχίζω.

On the one hand, these parables in Luke 5 represent Jesus’s reasoning with his critics that to resist him and his …

Gamifying The Classroom: An Interactive Literature Curriculum, Ella Mikulecky

Undergraduate Honors Theses

This thesis highlights an interactive literature curriculum that I have created to help youth engage more deeply with classical literary works. It takes inspiration from many existing collegiate-level curricula that fuse historical simulations with literary studies and adapts those teaching methods for high-school-age students. It also utilizes a variety of different teaching philosophies, game mechanics, and literary practices to create an ideal course for fostering engagement. This thesis provides a small sample of the curriculum along with a teacher’s handbook and reports the results of a pilot program conducted in the summer of 2025.

Mamma Mia: A Study Of Catholicism, Secularization, And Their Influences On Modern Italian, Lara Zanotti

Undergraduate Honors Theses

This study explores the relationship between religion and language by examining how Catholicism and secularization have shaped modern Italian. While the historical influence of the Catholic Church on Italian is well established, less attention has been given to how recent secularizing trends have transformed the language at lexical, discursive, and sociolinguistic levels. Addressing this gap, the study asks: how have Italy’s deep-rooted Catholic traditions and its more recent shift toward secularization influenced the meanings, frequency, and use of religiously rooted expressions in modern Italian?

Using a mixed-methods approach, this project combines corpus-based linguistic analysis with qualitative analysis. Diachronic data from …

Ai-Ready Libraries Require Ai-Ready Librarians: Building Organisational Capability For Digital Transformation, Salihin Mohammed Ali

Research Collection Library

Academic libraries worldwide are rapidly experimenting with artificial intelligence (AI) to enhance research, learning, discovery, operations, and user engagement. However, many institutions continue to approach AI adoption primarily through isolated pilots, individual experimentation, or technology-centric initiatives. While these efforts generate innovation, they often struggle to scale sustainably without corresponding organisational capability development. This presentation argues that AI-ready libraries require AI-ready librarians and proposes an organisational capability approach for sustainable AI transformation in academic libraries. Drawing from the development of a library-wide AI strategy plans at Singapore Management University, the presentation explores how AI capability-building can be operationalised across diverse functional …
