The first step in doing so is understanding the mechanisms that govern health and immune response and find ways to appropriately modulate them to improve animal health and productivity. The objective of this study is to use multi-omic techniques to understand breed-specific immune responses in sheep that may contribute to their resistance and susceptibility to parasites and to a greater extent, immunocompetence. Known parasite-resistant breed, St. Croix (STC) were compared to parasite susceptible Suffolk (SUF) sheep for …

Macroinvertebrate Response To Two Highway Construction Projects In West Virginia, Brenden Nauman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Highway development and construction are frequently required to provide efficient transportation for an increasing human population. Specific to the Appalachian region, highway development has been a major goal since the mid 1900’s, with the aim of promoting economic growth and ease of travel. While highways provide necessary services to humans, their construction and presence often impact nearby waterways through multiple mechanisms including sedimentation and urbanization. To understand the degree of impact, streams are often monitored using biological data, which can be used to quantify effects. In this work I used freshwater macroinvertebrate communities to monitor changes in stream health surrounding …

Experimental Evaluation Of 100 Ft X 10 Ft Frp Truss Pedestrian Bridge, Ashish Dhital

Graduate Theses, Dissertations, and Problem Reports (ETD)

ABSTRACT

Experimental Evaluation of 100 ft x 10 ft FRP Truss Pedestrian Bridge

Ashish Dhital

FRP truss bridges are now increasingly used in pedestrian bridge applications due to their high strength-to-weight ratio, corrosion resistance, better impact performance compared with conventional materials, and ease of assembly. These advantages make FRP systems attractive for accelerated construction, remote-site installation, and environments where steel or reinforced concrete bridges may experience corrosion-related deterioration. Due to insufficient data on both strength and serviceability (i.e deflection, frequency) performances. Full-scale testing of FRP pedestrian bridges of longer spans (50’-100’) is needed to better understand the dynamic behavior, long-term …

Swarm Of One: Self-Organization In Multicellular Robots, Trevor Riley Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Designing robots traditionally relies on centralized, top-down methods that constrain adaptability and resiliency, producing systems optimized for specific tasks. However, such systems often fail in complex environments, such as extraterrestrial, disaster, or natural settings, where designers cannot foresee every scenario a robot may encounter. Achieving autonomy in these contexts requires robots that are resilient and capable of adapting to the unknown. Multicellular organisms exhibit this adaptability through self-organization, where complex structures and behaviors emerge from local interactions among their cells. Such organisms can be viewed simultaneously as a single entity and a swarm of cooperating cells, i.e., a Swarm-of-One.

Comparison Of Three Methods In Diagnosing Maxillary Transverse Discrepancy, Madison Hull Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction

There are several different methods in determining the maxillary transverse discrepancy (MTD). In specific, MTD can be determined with the help of a cone beam computer tomography (CBCT), 3D scan and models, or simply a 2D occlusogram.  Do they provide the same MTD values for diagnosing transverse discrepancies? A patient may need a certain amount of skeletal and dental expansion based on a diagnosis of MTD, but this amount may vary depending on the diagnosis method used. There is a lack of knowledge in the literature comparing 2D and 3D methods in determining MTD. Currently, methods in measuring MTD …

Soil greenhouse gas production, aggregate stability, total soil C:N, pH, and soil organic matter …

Racial Resentment, Immigration Attitudes, And The Politics Of State Immigrant Policy Adoption In The United States, Cindy Osei Agyemang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Immigration remains one of the most contested public policy issues in the United States, and racial attitudes have become increasingly important in shaping public opinion and political debate. While prior research has shown a strong relationship between racial resentment and restrictive immigration attitudes, less is known about whether these attitudes extend to legislative discourse and the adoption of immigrant-inclusive state policies. This dissertation addresses that gap by examining the relationship between racial resentment and immigration politics across three levels of analysis: public opinion, legislative discourse, and state policy adoption. Using a mixed-methods research design, the study combines quantitative and qualitative …

Graft: Graph-Augmented Framework With Vision Transformers For Multi-Label Classification, Ghazaleh Mirzaee

Graduate Theses, Dissertations, and Problem Reports (ETD)

Multi-label classification of thoracic diseases from chest X-ray images poses a distinctive challenge: patients rarely present with a single isolated pathology, and automated systems must identify multiple co-occurring conditions simultaneously from a single radiograph. Standard classification architectures treat each disease label as an independent binary decision, failing to capture the statistical co-occurrence patterns, spatial anatomical relationships, and visual feature similarities that characterize multi-disease presentations in clinical data. Class imbalance and incomplete labels compound these problems. In NIH ChestX-ray14, the rarest pathological class has only 227 training instances, and many co-occurring conditions go unlabeled because radiologists focus their reports on the …

Cell-To-Pack Modeling Of Lithium-Ion Batteries: From Bayesian Parameterization To Pack-Level Optimization, Derek Slack

Graduate Theses, Dissertations, and Problem Reports (ETD)

One of the major hurdles for electric or hybrid aviation is the comparative energy density between lithium-ion batteries and jet fuel. To help obtain maximal power-to-weight ratio in electric or hybrid powertrains the battery pack design should be optimized to be as light as possible while meeting thermal safety and power requirements. The proposed solution is an optimization routine beginning with a cell-level parameter estimation of lithium-ion battery cells, where data driven Bayesian Gaussian Processes replace empirically or analytically derived parameters in a first principles electrochemical model in PyBaMM, as functions of the transient state of the cell. The resulting …

Assessment Of Emissions Factors For Produced Water And Other Atmospheric Liquid Storage Tanks On Natural Gas Sites, David Glenn Childs

Graduate Theses, Dissertations, and Problem Reports (ETD)

As the US natural gas (NG) sector continues to grow, concerns have increased regarding the effects and increasing volume of greenhouse gases emitted into the atmosphere. While NG is a cleaner burning fuel than diesel and gasoline, unburned methane (CH₄) has a global warming potential (GWP) 27-30 times that of carbon dioxide (CO₂). To better quantify CH₄ emissions on NG sites, the US Department of Energy (DOE) granted West Virginia University (WVU) funding to collect direct measurements at well sites and compressor stations.

In this work, a total of 18 sites, including controlled and uncontrolled …

Empowered Choices: A Quality Improvement Women’S Health Initiative In Faith-Based Nursing For Women Recovering From Substance Use Disorder, Jennifer Mewshaw

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: Women with substance use disorder (SUD) face higher rates of unplanned pregnancy, reproductive infections, and delayed prenatal care. Faith community nurses (FCNs) often already serve within this community and have a long history of promoting public health interventions. However, they lack the knowledge and confidence in sexual and reproductive health (SRH) education.

Evidence Review: A literature review identified barriers to SRH care for women with SUD and the role of FCNs in community and public health interventions. Evidence supports providing FCNs with the knowledge and skills to deliver SRH education and support for women with SUD using trauma-informed and …

The Tax Governance Triangle: An Attitudinal Theory Of State Capacity And Tax Compliance., Abdul Wahid Uqaily

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Tax Governance Triangle: An Attitudinal Theory of State Capacity and Tax Compliance

Abdul Wahid Uqaily

Variation in states' extractive capacity is a central puzzle in comparative politics and political economy. Existing scholarship explains this variation largely through institutional quality, administrative capability, or coercive enforcement, with less attention to the attitudinal foundations that shape key actors' willingness to sustain an effective fiscal system. This dissertation addresses that gap by asking: how do the attitudes and behaviors of citizens, bureaucrats, and elites shape variation in a state's extractive capacity?

To answer this question, the dissertation develops the “Tax Governance Triangle” and …

Development Of A Protocol To Improve The Use Of Diabetes-Specific Formula, Lauren Nicole Sanetrik

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: Enteral nutrition (EN) is often necessary for hospitalized patients who are unable to meet their nutritional needs orally. Patients with diabetes mellitus (DM) receiving EN are at risk of hyperglycemia, which contributes to poor wound healing, infection, and prolonged hospitalization. Diabetes-specific formulas (DSFs) are designed to optimize glycemic control compared with standard formulas (SFs); however, their use is inconsistent due to the absence of standardized protocols.

Purpose: The purpose of this Doctor of Nursing Practice (DNP) quality improvement project was to implement and evaluate a protocol to increase DSF utilization among patients with DM receiving EN, with the goal …

Does Diverse Seeding Adoption Reduce Production Costs? The Case Of Diverse Forage Seeding Strategies In West Virginia., Ivan Andres Wong

Graduate Theses, Dissertations, and Problem Reports (ETD)

Feed and harvested forage represent a major share of production costs in Appalachian cow-calf systems, where a pronounced summer forage gap forces producers to rely on purchased hay. This thesis evaluates whether adopting diverse forage seeding strategies reduces production costs relative to the existing pasture management practice, accounting for the spatial heterogeneity of West Virginia’s production environments. The analysis proceeds in two steps. First, an unsupervised K-means clustering of 14 farms enrolled in the NRCS Conservation Innovation Grant field trial groups the farms into two agroclimatic clusters, Highland-Cool and LowlandWarm, using elevation, growing-season Growing Degree Days, growing-season precipitation, and soil …

Cultural Perceptions And Willingness Or Reluctance To Use Ai Chatbots For Emotional Support By International African Students In Higher Educational Institutions In The United States, Zakariah Issah

Graduate Theses, Dissertations, and Problem Reports (ETD)

The increasing use of artificial intelligence (AI) chatbots for emotional support underscores the need to understand how cultural perceptions shape their adoption among international African students in higher education institutions in the United States. Guided by the Technology Acceptance Model (TAM) and Social Stigma Theory, this qualitative study explored the perceptions, motivations, and barriers influencing the use of AI chatbots for emotional support. Semi-structured interviews were conducted with 20 undergraduate and graduate students from 10 African countries. The findings reveal that participants viewed AI chatbots as conditional and situational sources of emotional support rather than replacements for human relationships. Convenience, …

Examining Drivers Of Brook Trout (Salvelinus Fontinalis) Fecundity And Recruitment In Central Appalachian Headwater Streams, Emilee Esther Briggs

Graduate Theses, Dissertations, and Problem Reports (ETD)

The persistence of fish populations depends on the repeated production and survival of new year classes, also referred to as recruitment. Recruitment is broadly defined as the number of individuals in a fish population or stock that survive to a specific stage. However, the broader recruitment process reflects the cumulative outcome of many earlier life stages, including egg survival, fry emergence, and survival through the recruitment period. As a result, recruitment can vary substantially among years and populations, producing strong or weak year classes that influence population abundance and persistence. Understanding why recruitment varies is therefore central to fisheries ecology …

Graduate Theses, Dissertations, and Problem Reports (ETD)

OBJECTIVES: Artificial food dyes (AFD+) are an increasing policy concern in the U.S., particularly in children’s foods. West Virginia’s House Bill 2354, the first statewide AFD+ ban implemented in K-12 schools, restricts seven AFD+ in state-funded meals. Little is known about how AFD+ bans are perceived or implemented. This study examined how the ban functioned within school food systems and the barriers and facilitators experienced by school stakeholders within the initial year of implementation during the 2025-2026 school year.

METHODS: A cross-sectional, observational mixed-methods study was conducted among implementers, enforcers, and receivers of the policy. A survey tool …

Innovative Strategies For Stabilizing Zinc Anodes: From Molecular Design To Practical Zinc-Ion Batteries, Nhat Anh Thi Thieu

Graduate Theses, Dissertations, and Problem Reports (ETD)

Aqueous zinc-ion batteries (AZIBs) have become increasingly attractive as grid-scale energy storage solutions due to their safety, low cost, and environmental friendliness. However, the anode-electrolyte interface in AZIBs is prone to instability due to severe dendrite growth, self-corrosion, parasitic water-induced side reactions, and hydrogen evolution reactions (HER), which collectively lead to poor cyclability. To date, various interfacial engineering strategies have been investigated to address these challenges and improve the stability of Zn metal anodes. This dissertation presents a unified strategy for regulating Zn deposition through synergistic electrode and electrolyte design in laboratory-scale coin cells and then applies these concepts to …

Dielectrophoretic Biomarkers For Cancer Detection And Cell Analysis: Integrating Microfluidics And Ai, Raphael Olumide Oladokun

Graduate Theses, Dissertations, and Problem Reports (ETD)

Pancreatic ductal adenocarcinoma (PDAC) carries a five-year survival rate of 13%, driven largely by late-stage diagnosis and the absence of sensitive noninvasive screening tools. Current diagnostic methods lack the sensitivity to detect disease-associated systemic changes at early and precancerous stages, representing a critical clinical gap. This dissertation addresses the central hypothesis that PDAC and its pathological subtypes induce measurable, disease-associated electrophysiological changes in circulating PBMCs that can serve as correlative liquid-biopsy biomarkers. To test this hypothesis, this work asks: can dielectrophoresis (DEP), impedance and zeta potential analysis with AI-assisted classification distinguish benign pancreatic conditions (non-malignant control), precancerous lesions (primarily IPMNs), …

Romantic Narrative In Three Early Piano Cycles By Robert Schumann: Papillons, Op. 2; Fantasiestücke, Op. 12; And Kinderszenen, Op. 15, Lingqing Huang

Graduate Theses, Dissertations, and Problem Reports (ETD)

This research project compares Romantic instrumental narrative in Robert Schumann’s Papillons, Op. 2; Fantasiestücke, Op. 12; and Kinderszenen, Op. 15, with particular attention to how pianists communicate cyclic continuity in performance. In this study, narrative continuity refers to relationships formed across ordered short pieces through contrast, interruption, return, literary association, fantasy, memory, tonal and motivic recall, and the shaping of sound and time. Comparative score analysis shows that Schumann creates a distinct form of continuity in each cycle. In Papillons, he creates a public, ballroom-based form through masquerade, waltz-like dance, abrupt entrances, interruption, and the gradual dissolution of the social …
