The project involved the evaluation and treatment of eleven neurological patients across inpatient and outpatient settings. Guided by Warren’s Hierarchy of Visual Perceptual Skills and Toglia’s Dynamic Interactional Approach, the project emphasized stabilizing foundational visual skills before progressing to higher‑level visual-perceptual tasks and used near …

Fragile Patients, Intentional Care: Nonpharmacological Pain Management Treatment Approaches In The Neonatal Intensive Care Unit (Nicu), Kristie A. Moeller

Occupational Therapy Capstone Presentations

The aim of this project was to increase clinical skills in a level III neonatal intensive care unit (NICU) and explore how nonpharmacological occupational therapy (OT) interventions impact pain management in the NICU for a variety of patients. Due to the increasing rates of admissions to the NICU and the impact that pain has on child development there was a clear need to gain skills to create interventions that would minimize the effect on infant development (Martin & Osterman, 2025; Pineda et al., 2025). The needs assessment revealed the need for occupational therapists (OTs) role in nonpharmacological pain management to …

Ccr5 Sulfopeptide Library And O-Glycosylated Amino Acids As Chemical Tools For Probing Chemokine Receptor Recognition, Mostafa Mohammed Mohammed Ali Eldeen

Electronic Theses and Dissertations

Chemokine-receptor interactions play a central role in immune regulation and disease pathogenesis, particularly through CCR5, a receptor engaged by chemokines such as CCL3, CCL4, and CCL5. Post-translational modifications of the CCR5 N-terminus—including tyrosine sulfation at positions 3, 10, 14, and 15, and O-glycosylation at serine 6—critically modulate chemokine recognition and selectivity. However, the impact of specific sulfation patterns on chemokine binding and the synergistic effects of combined sulfation and glycosylation remain incompletely understood. This thesis presents a two-project chemical approach to systematically investigate CCR5 post-translational modifications. In Project 1, a comprehensive 16-member library of CCR5???? sulfopeptides representing all possible combinations …

Study Of Binary Hypothesis Testing Using Deep Learning, Sadhana Geddam

Electronic Theses and Dissertations

Binary hypothesis testing is a fundamental problem in statistical signal processing and decision theory, with applications in communications, radar systems, and distributed sensor networks. Classical approaches, particularly the likelihood ratio test (LRT), provide optimal detection performance when the underlying probability distributions are known. However, in many practical scenarios, the resulting decision rules can become analytically complex or computationally intensive, especially in multi-sensor and dependent data settings.

This thesis investigates the use of neural networks for binary hypothesis testing under diverse statistical conditions. A data-driven framework is developed to learn decision rules directly from observed data, enabling the approximation of likelihood …

A Revised Quantifier Variance And Its Implications On Vagueness, Isaac Alexander Huling

Electronic Theses and Dissertations

This paper argues that the Special Composition Question has no substantive answer, not because compositional talk is empty but because the physical structure it tracks does not have the form that would privilege a unique answer. The argument accepts Sider’s methodological premise that the world must provide structure beyond description if ontological vocabulary is to mean anything, and deploys that apparatus against his specific application of it to composition. Constraint processes among a system’s parts – the forces and interactions that hold rigid bodies together, maintain organisms, bind solar systems – satisfy every condition Lewis required of reference magnets. They …

Murdoch's Metaphorical And Mystical Moral Metaphysics, William Jade Langley

Electronic Theses and Dissertations

In this project, I explain the mysticism found in Iris Murdoch’s The Sovereignty of Good, emphasizing what the illustrative thought experiments and metaphors are meant to explain. To do this, I introduce her understanding of G. E Moore’s moral realism and compare this with how Bertrand Russell understands mystical intuition and revelation. Then, to understand how we can still do moral philosophy when morality is fundamentally mystical, I compare Murdoch’s usage of metaphor with that of Victoria Welby, who also takes metaphorical understanding to be crucial to our understanding of the world. Though Welby goes further than Murdoch in saying …

Media Framing Of Peace And Justice In Post Conflict Societies: Rwanda And Colombia In Focus, Ahmer Anwar Khan

Electronic Theses and Dissertations

This study investigates how traditional journalism frames peace and justice in post-conflict societies, using Rwanda and Colombia as comparative case studies. It explores the role of media in shaping public discourse around transitional justice, reconciliation, and national healing. The findings indicate that Rwanda’s media adopted a justice-first framing, emphasizing accountability and moral restoration through mechanisms such as the International Criminal Tribunal for Rwanda (ICTR) and the Gacaca courts. In contrast, Colombian journalism during the 2012–2016 peace negotiations with the FARC guerrilla group prioritized peace-first framing, portraying dialogue and reintegration as essential to ending decades of violence. These divergent approaches reflect …

Semantically Grounded Evaluation For Open-Vocabulary Human-Object Interaction Detection, Maja Noack

Electronic Theses and Dissertations

Open-vocabulary human–object interaction (HOI) detection is a step towards building scal¬able systems that generalize to unseen interactions in real-world scenarios and support grounded multimodal systems that reason about human–object relationships. However, stan¬dard evaluation metrics, such as mean Average Precision (mAP), treat HOI classes as dis¬crete categorical labels and fail to credit semantically valid but lexically different predictions (e.g., “lean on couch” vs. “sit on couch”), limiting their applicability for evaluating open-vocabulary predictions that go beyond any predefined set of HOI labels. I introduce SHOE (Semantic HOI Open-Vocabulary Evaluation), a new evaluation framework that incorporates semantic similarity between predicted and ground-truth …

Secondary English Teachers’ Perceptions Regarding The Impact, If Any, Of Shifts In The Emphasis Of History Education On Students’ Comprehension Of Literature, Bailey J. Poole

Electronic Theses and Dissertations

This qualitative study explored secondary English teachers’ perceptions of the emphasis on history education and its perceived impact on their students’ comprehension of literature. This research used an interpretivist approach and a conceptual framework shaped by schema theory and constructivism to understand whether teachers perceived a shift in the value of history education, how they described such shifts, if any, and how they responded instructionally to those shifts, if necessary.

Data was collected through six semi-structured interviews with 11th and 12th grade English Language Arts teachers from public high schools in Mississippi, each with a minimum of ten years teaching …

Computational Investigation Of Nanoconfinement Effects On Gas Separation In Copolymer/Ionic Liquid Membranes, Azam Salmankhani

Electronic Theses and Dissertations

The separation of carbon dioxide (CO2) from methane (CH4) is a critical process in natural gas upgrading and carbon management, yet conventional membrane materials suffer from inherent trade offs between selectivity and permeability. Ionic liquid (IL)-based membranes offer high CO2 affinity and tunable chemistry, but the mechanisms governing gas transport under nanoconfinement remain poorly understood, especially the roles of confinement geometry and interfacial ordering in controlling gas selectivity and permeability. This dissertation addresses this challenge through a multiscale computational investigation of nanoconfined ionic liquid membranes. Mesoscale simulations are used to determine how block copolymer composition and ionic liquid loading control …

Board-Level Operating System Infrastructure In Rust, Lydia Klaus

McKelvey School of Engineering Graduate Student Theses & Dissertations

Memory and multi-threading problems are the cause of many exploits and security vulnerabilities, and errors of this nature are easy to cause in programming languages such as C and C++. Despite this, these languages are still heavily used for systems programming and underpin the majority of operating system kernels. This is partially due to a lack of suitable replacements; however, Rust is becoming more prominent as an option for systems programming. This language features a much more stringent approach to memory and multi-threading safety. It also aims to support a wide range of hardware targets, including microcontrollers, which have long …

Establishing Caenorhabditis Elegans As A Platform For Bioaccumulation And Selectivity Screening Of Anthelmintic Compounds, Jiarui Li

McKelvey School of Engineering Graduate Student Theses & Dissertations

To address the cuticular barrier in anthelmintic discovery, this study establishes a bifurcated framework in Caenorhabditis elegans. First, HPLC-based quantification of 14 PIM inhibitors revealed that cuticular penetrance is primarily dictated by phylogenetic lineage (Clade V) rather than ecological niche. Specifically, C. elegans demonstrated a significant pharmacokinetic correlation with the hookworm Ancylostoma ceylanicum (Clade V) but not the whipworm Trichuris muris (Clade I), validating it as a superior surrogate model for hookworm bioaccumulation. Within this small molecule inhibitor library, SGI-12was identified as a lead candidate with superior potency against C. elegans and bioaccumulation. Second, target validation using a C. …

Side-To-Side Differences In Three-Dimensional Femoral Head Coverage Associated With Initial Symptom Development In Patients With Bilateral Developmental Dysplasia Of The Hip, Jiayi Sun

McKelvey School of Engineering Graduate Student Theses & Dissertations

Developmental dysplasia of the hip (DDH) is characterized by insufficient acetabular coverage of the femoral head and is a recognized cause of hip pain, instability, and early osteoarthritis. Although bilateral deformity is common, symptoms often first develop in only one hip. The purposes of this study were: (1) to determine whether, in patients with bilateral DDH, side-to-side differences in three-dimensional (3D) femoral head coverage vary according to radiographic symmetry defined by the lateral center-edge angle (LCEA); and (2) to determine whether hips that appear radiographically symmetric still demonstrate focal 3D asymmetry.

This retrospective imaging-based study included patients with bilateral DDH …

A group of Arkansas State University civil engineering students participated in that competition in Spring 2026.

Federalism, Fragmentation, And The Limits Of Universal Welfare In The United States: A Comparative Analysis Of Germany And Sweden, Jacqueline Arena

Political Science

This paper examines why the United States welfare state struggles to achieve universal social protection, focusing on the role of federalism, political ideology, and public opinion. It argues that the U.S. welfare state is structurally fragmented due to the division of authority between federal and state governments, which produces uneven, inconsistent, and often inadequate access to social benefits. This fragmentation is rooted in historical developments, including New Deal era political compromises, racialized policy exclusions, and resistance from organized interest groups, which embedded decentralization and inequality into the system’s foundation. Using Gøsta Esping-Andersen’s welfare regime typology and T.H. Marshall’s concept of …

Cell-Type Specific Control Of Visual Fixation In Drosophila Melanogaster, Meagan Leung

Biological Sciences

Navigation in complex environments requires precise visual processing. To move effectively through their surroundings, animals must orient toward and maintain fixation on objects of interest to preserve a stable heading. However, the neural mechanisms underlying this behavior remain poorly understood. We use Drosophila melanogaster as our model organism because its visual behavior can be precisely measured and the availability of genetic tools which enables us to perturb the underlying neural circuits. Using a closed-loop virtual reality environment combined with locomotion tracking, we developed a stimulus protocol that reliably elicits fixation responses. To determine whether specific visual neurons drive fixation responses, …

Albany City As A Case Study In Language Mapping, Storm Pupina

Linguistics

This thesis uses Albany, NY, as a case study in urban language mapping, following the example of many other language mapping projects, most notably the NYC Language Mapping Project. Albany's languages and linguistic features were analyzed to better understand the area's linguistic ecology and ongoing heritage-language maintenance efforts. Various types of American Census data were compared to reach the conclusions. Despite not being a major city, Albany is bustling with both new and old language communities. Similar efforts with more varied data-gathering tactics would greatly benefit other American urban landscapes.

Supply Constraints And Domestic Migration As Drivers Of U.S. Housing Price Appreciation, Vasu Patel

Economics

When the Federal Reserve raised rates from near zero to 525 basis points between 2022 and 2023, standard theory predicted a broad correction in U.S. housing market. In most metropolitan areas, that correction did not arrive. This paper examines why housing price appreciation persisted across cities with fundamentally different structural characteristics, and which factors best explain the cross-city variation in appreciation rates observed across the nation. Using a panel of 83 Metropolitan Statistical Areas across four symmetric 24-month periods from December 2017 through December 2025, each aligned with a distinct Federal Reserve rate period, the study estimates OLS models with …

Low-Cost Rf Exposure Monitoring With Tinyml Prediction, Sanad Sahawneh

Nanoscale Science & Engineering (discontinued with class year 2014)

The proliferation of wireless technologies has produced a dense, increasingly heterogeneous radio-frequency (RF) environment that surrounds modern life. While regulatory bodies such as the Federal Communications Commission (FCC) and the World Health Organization (WHO) maintain exposure guidelines, the tools that ordinary people, educators, and small institutions can use to actually observe RF exposure in their own spaces remain expensive, specialized, and largely confined to professional laboratories. Spectrum analyzers and calibrated field probes routinely cost between five hundred and one hundred thousand dollars per unit, placing continuous local monitoring out of reach for most environments where exposure questions are most natural …

Dissertations

                                                                Abstract

This autoethnographic study focuses on Post-Traumatic Stress Disorder (PTSD) among U.S. veterans and the policies and practices that impact life outcomes. The research answers the questions: (1) what insights emerge from the author’s embedded advocacy experience; (2) what systemic barriers impede veterans’ access to PTSD treatment; and (3) how does military culture shape help-seeking behavior. This research draws on the author’s multigenerational and institutional ties to military service—as descendant of a Korean-era veteran, Marine and Army servicemember, VA employee, and veteran advocate. The researcher constructs detailed autoethnographic and composite narratives of the lived experiences of service members who develop …

The Concentration Controversy, Matthew Urquiaga

Business/Business Administration

This thesis examines how U.S. equity market concentration affects investment performance. Using CRSP data from 1999 to 2024, we construct monthly concentration measures, including the Herfindahl-Hirschman Index (HHI), the adjusted HHI, the Top 20 market share, and each month’s expanding-window concentration quintiles. We document subsequent stock returns by quintile and find weak evidence of higher stock performance in Quintile 3 conditions. A second part of the analysis uses Morningstar’s universe of actively managed U.S. equity funds to evaluate benchmark-adjusted returns (BARs) across the full equity style box. The results show that active managers deliver their highest BARs in moderate concentration …

An Experimental Study Of The Morphology Of Dna-Carbon Nanotube Hybrid Structures In Direct Dna Sequencing, Avery P. Davis

Biomedical Engineering Undergraduate Honors Theses

Hybrid structures formed between single-stranded DNA (ssDNA) and single-walled carbon nanotubes (SWCNT) have emerged as promising components in future direct DNA sequencing technologies due to their unique morphological and electronic properties. The nanoscale configuration of these hybrids, including the DNA wrapping angle, pitch, and contour behavior, directly influences their potential for stable electronic readout. This thesis presents an experimental study of DNA-SWCNT hybrid morphology using a fixed, reproducible wrapping protocol designed to minimize environmental variability and isolate the influence of DNA nucleotide sequence on hybrid structure. As described in prior work, this protocol produces well-dispersed hybrids suitable for high-resolution imaging. …

Long-Term Stimulant Use Is Associated With Normalized White Matter Integrity In The Vta-Nacc Pathway In Adolescents, Isaac T. Arsenault

Biological Sciences Undergraduate Honors Theses

Medical practitioners are diagnosing Attention-Deficit/Hyperactivity Disorder (ADHD) at a high and ever-increasing rate. The use of stimulant medication to treat ADHD is also increasing and is associated with changes in the brain. Past research found that children with ADHD have lower volume in reward neurocircuitry, such as the ventral tegmental area (VTA) and the nucleus accumbens (NAcc). Research has also found that stimulant usage in those with ADHD might “normalize” the reward circuits. However, few longitudinal studies have directly tested the long-term effects of stimulant medication on brain development. Here we tested whether long-term stimulant use is associated with changes …

A Behavior Analytic Blueprint For Rapport-Building: Investigating The Key Elements For Success, Nelmar Jacinto Cruz

Theses and Dissertations

Rapport can be defined as a positive relationship between people built through specific actions. Building rapport can benefit organizations by improving performance and increasing work satisfaction. Despite these benefits, research on rapport remains scarce. Curry et al. (2019) completed the most recent rapport study and found that rapport-building led to increased productivity and discretionary effort. The present study replicated and extended Curry et al. (2019) and addressed three limitations of their research: the lack of a control group, the large disparity in time spent with the experimenter, and the rigidity of their rapport conversation script. The study was completed in …

A New Approach To Generate Combinatorial Patterns In Logical Analysis Of Data And Its Application To Predict College Retention, Salihah Ahmed E. Jaafari

Theses and Dissertations

Student retention and degree completion remain central challenges for higher-education institutions, with significant implications for student success, institutional effectiveness, and public accountability. While advances in predictive analytics have enabled earlier identification of students at risk of withdrawal, many commonly used machine learning approaches suffer from limited interpretability, constraining their practical usefulness for advising, intervention, and policy decision making. This dissertation addresses the problem of predicting student persistence by developing and evaluating optimization based, interpretable classification models within the Logical Analysis of Data (LAD) framework. Building on existing LAD formulations, this research introduces two novel pattern generation models, the Best Term …

What Happens When Leaders Don’T Live Up To The Ideal? How The Leadership Perception Gap Can Undermine Leader Development And Intentions, Julia Macgregor-Peralta

Theses and Dissertations

Despite decades of research on leadership development, we know surprisingly little about why capable, confident people choose not to pursue leadership. This study introduces the Leadership Perception Gap (LPG), a construct that captures discrepancies between ideal leader views and the leaders people actually observe, and tests whether those discrepancies reduce the desirability of leadership roles. LPG was assessed using latent congruence modeling (LCM) to compare ideal leader ratings with vignette-based leader evaluations. The vignettes manipulated leadership style (agentic, communal, balanced) and team composition (all-male, all-female, balanced). Participants were randomly assigned to one condition and evaluated their interest in joining the …

Hdra-Fusion: Hybrid Detection With Routed Architecture For Manipulation-Aware Ai Face Forgery Detection, Omar Ebeid

Theses and Dissertations

With the rapid advancements in artificial intelligence-based image generation and manipulation tools, it is extremely difficult to detect if an image is genuine or artificially crafted. Despite extensive research in this area, existing image detection systems suffer from three major problems: suboptimal cross-dataset generalization due to shortcut learning of dataset-specific patterns, unreliable probability estimates due to domain shift, particularly in cross-manipulation evaluation settings, and an inability to detect images manipulated by multiple types of manipulations within a single detection framework. To address these limitations, we propose HDRA-Fusion (Hybrid Detection with Routed Architecture), a framework built on the conclusion that different …
