Global China In Pakistan: Mixed-Methods Analysis Of Symbolic Domination, Social Media Geopolitics, And Security Corridors, Davide Giacomo Zoppolato

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation explores the discursive and material dimensions of China’s global rise through a case study of the Belt and Road Initiative (BRI) in Pakistan. As China becomes a leading provider of development finance, its infrastructure-led approach is reshaping geographies across the Global South. Focusing on the China–Pakistan Economic Corridor (CPEC)—the BRI’s flagship project—I examine how Chinese and Pakistani actors co-produce development through discourses, infrastructures, and security regimes. Structured around three articles, the dissertation analyzes: (1) the official diplomatic discourses of Chinese state institutions and their reception by Pakistani media outlets; (2) the curated geopolitical discourses of Chinese social media …

P23h Rhodopsin Accumulation Disrupts Synaptic Protein Levels In Rod Photoreceptors, Samantha Thompson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Rod photoreceptors are specialized neurons located in the retina, the neural tissue that lines the back of the eye. Rod photoreceptors are necessary for dim light and peripheral vision through the photoactivation rhodopsin (Rho). Rho is synthesized in the inner segment of rods before being unidirectionally trafficked to the outer segment. In diseases such as retinitis pigmentosa (RP), Rho trafficking can be disrupted, leading to progressive rod cell death. In many cases of RP, Rho is mislocalized to the rod photoreceptor synapse (“spherule”). The impact of Rho mislocalization on spherule structure and protein organization is poorly understood. We hypothesize that …

Studies reveal that over 70% of individuals worldwide in need of mental health services do not receive appropriate care. Digital health technologies have the potential to enhance mental health services by making them more accessible and affordable. Despite the increasing popularity of mental health mobile applications (mHealth), there remains a lack of robust evidence of their effectiveness and the level of user trust, particularly in areas …

It Takes Two To Tango: The Overlooked Process Of Co-Creation In Services Marketing, Natalie A. Marquart

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation investigates the mechanisms of effective co-creation in patient-provider interactions within the U.S. healthcare system, a critical area given pervasive systemic frustrations and the dyadic nature of care. Grounded in Social Cognitive Theory and Service-Dominant Logic, the research proposes a conceptual model where patient self-efficacy fosters cooperation, mediated by the dimensions of symmetry, alignment, and agreement, ultimately influencing patient outcomes. Perceived response efficacy is hypothesized to moderate this relationship. A mixed-methods approach was employed, consisting of two complementary studies. Study 1 utilized qualitative, semi-structured interviews with 20 patients and 5 healthcare providers to deeply explore how self-efficacy, perceived response …

From Bobcat To Bursts: Multi-Messenger Constraints On Supermassive Black Holes And Binaries, Jessica Sydnor

Graduate Theses, Dissertations, and Problem Reports (ETD)

Supermassive black hole binaries (SMBHBs) are a natural consequence of hierarchical galaxy formation and evolution. When galaxies merge, their central supermassive black holes (SMBHs) are expected to form bound pairs that evolve from kiloparsec to sub-parsec separations under the influence of dynamical friction, stellar scattering, and gas dynamics. Ultimately, these SMBHs reach the regime where gravitational wave emission dominates and drives the final inspiral and coalescence. Understanding the formation, evolution, and observational signatures of SMBHBs is critical to advancing multi-messenger astrophysics, particularly in the era of pulsar timing arrays (PTAs) and the upcoming Laser Interferometer Space Antenna (LISA), which opens …

Graduate Theses, Dissertations, and Problem Reports (ETD)

This research examined digital news coverage of the East Palestine train derailment to determine the frames and dominant frames used in both local and national coverage of the disaster, and whether these frames differed over time. Specifically, this research used a content analysis of digital newspaper articles from five media outlets—three national level and two local level—and applied the frames identified from Colistra’s (2010) study of print news coverage of the 1972 Buffalo Creek mine disaster. Results revealed significant differences between the most frequently used frames between local and national coverage, shifts in frame usage over time within each media …

Investigating The Physiological, Metabolomic, And Transcriptomic Changes In Response To Telomerase Deletion In Saccharomyces Cerevisiae, Taizina Momtareen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Telomerase is an enzyme found in rapidly dividing cells that maintains chromosome ends and prevents the loss of genetic information during cell division. When telomerase is inactive, cells gradually lose their telomeres and eventually stop dividing. In yeast, a rare subset of cells can bypass this growth arrest by switching to a recombination-based mechanism to maintain telomeres. Therefore, yeast provides a powerful system to study this adaptation, as telomerase-deficient strains can generate 'survivors' that mimic the Alternative Lengthening of Telomeres (ALT) pathway observed in some human tumors. In this work, my goal was to examine how a telomerase-null (TLC1 …

Rare Earth Element Recovery From Acid Mine Drainage Using Ion Exchange And Selective Precipitation Processes, Paubla Andrea Gallego Lopez

Graduate Theses, Dissertations, and Problem Reports (ETD)

Rare earth elements (REEs) are used in high-tech applications due to their electromagnetic and optical properties. As global demand for REEs surges, the limitation of primary mineral deposits has increased interest in alternative sources. One such source is acid mine drainage (AMD), which, although typically low in REE concentration, offers a promising avenue for recovery. Among the emerging recovery methods, ion exchange has shown promise due to its effectiveness at low concentrations and lower operational cost than conventional techniques such as acid leaching and solvent extraction.

This research focused on developing a recovery process by combining ion exchange with selective …

Distress Tolerance And Sleep Quality: Potential Moderating And Mediating Factors, Alivia Kay Murdock-Frazier

Graduate Theses, Dissertations, and Problem Reports (ETD)

Research has shown that insomnia and poor sleep quality are related to a variety of negative physical and mental health outcomes. There is emerging evidence that the psychological construct of distress tolerance is related to the quality of one’s sleep, including the presence of insomnia. However, few studies have explored how additional factors may be related to this association. This study aimed to replicate previous research supporting the association between distress tolerance and sleep and exploring this relation by examining three different hypotheses (e.g., health behaviors, perceived stress, and emotion regulation) that could potentially explain how these two variables are …

Systematic Methodologies For Magnetic Materials Design, Andres Tellez Mora

Graduate Theses, Dissertations, and Problem Reports (ETD)

Understanding and predicting the magnetic behavior of materials from first principles is one of the central challenges in condensed matter physics. This dissertation presents a systematic framework that bridges ab initio calculations, many-body physics, and effective spin models to analyze magnetic materials in particular, but also more general quantum systems. Starting from the electron many-body Hamiltonian and the second quantization formalism, we derive Density Functional Theory (DFT) and explain how magnetic properties emerge from exchange interactions and can be interpreted as perturbations to the magnetization density. To capture these effects efficiently, we construct Heisenberg models from first principles using the …

Characterization Of A Descending Neuron That Modulates Flight Performance And Provides Input Onto A Flight-Related Predictive Motor Circuit, Andisheh Balouchi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Descending neurons (DNs) play a critical role in sensorimotor integration by relaying motor information to the ventral nerve cord (VNC). Within the VNC, local interneurons, other DNs, and ascending neurons (ANs) make circuits with sensory and motor neurons to modify flies’ behavior. One important AN pair in Drosophila Melanogaster is mesothoracic ascending histaminergic neurons (MsAHNs), which are known to convey predictive wing motor signals to the brain. DNg32 is the primary upstream synaptic partner of MsAHNs, integrating DNg32 input with other inputs to generate predictive motor signals. The goals of this study were to 1) map the synaptic connectivity of …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Compared nationally, West Virginia currently ranks lowest for life expectancy, highest for drug related deaths and 35^th for access to adequate health (WV DHHR Organization Assessment & Strategic Plan, 2022). The state also ranks first in the nation for depression with one in four adults experiencing some form of depressive condition each year (CDC, 2020). The rurality of the state may limit social interaction and availability of medical treatment facilities (Brew et al., 2016).

The situation is even more dire for those in farming-related occupations. Farmers often struggle with management stress, utilizing appropriate coping strategies, and accessing mental health …

Not Far Enough: The West Virginia Human Rights Commission And The Civil Rights Movement, David Solomon

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis investigates the West Virginia Human Rights Commission and its action surrounding the Civil Rights Movement. The Commission represented the liberal ideals that led white moderates to be potent allies of the Civil Rights Movement. Throughout the years following its inception, the Commission investigated and documented many instances of Jim Crow that were crushing Black communities in West Virginia. However, the limits of its liberal approach prevented it from creating solutions that would address the power structures that supported discrimination in West Virginia. By the late 1960s, Black frustrations with the lack of meaningful change boiled over into riots …

From Sequencing To Conservation: Genomic Analysis Of Three Sportfish Species In West Virginia, Andrew Johnson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Situated in the Appalachian Mountains, one of the oldest mountain ranges on Earth, West Virginia waters boast rich ichthyofauna including native sportfish species walleye (Sander vitreus), largemouth bass (Micropterus nigricans), and muskellunge (Esox masquinongy). These three species are all native to the contemporary Ohio River watershed and play a major recreational and ecological role in local fisheries. Ecologically, all three species are apex predators and play a key role in ecosystems by directly influencing local fish assemblages. As dominant apex predators all three species are highly sought after in recreational fisheries with largemouth bass …

Optical Measurements Of Magnetic Fields In Low-Temperature Plasmas Via Quantum Spectroscopy, Tyler James Gilbert

Graduate Theses, Dissertations, and Problem Reports (ETD)

Accurate characterization of the magnetic field strength and direction within a plasma is increasingly important as experiments attempt to probe the physics of plasmas at kinetic scales. Non-perturbative laser-based diagnostics which are spatially and temporally localized—such as laser-induced fluorescence (LIF) and Thomson scattering for the measurement of ion and electron distribution functions, respectively—are increasingly relied on for measurements in laboratory plasmas. This work seeks to develop a spatially and temporally localized non-perturbative laser-based diagnostic for the measurement of magnetic fields in laboratory-relevant plasmas. Two such techniques are investigated here: Zeeman-split LIF and quantum beat spectroscopy (QBS).

Zeeman-split LIF measures the …

Police Abuse In America And The Search For Remedy, Howard Ryan

Graduate Theses, Dissertations, and Problem Reports (ETD)

The dissertation contends that, despite many diligent efforts—from mass protests to a presidential task force—America is not yet on path to remedying its outsized patterns of police abuse. The abuse problem is broadly characterized herein through a “triad” of over-enforcement, excessive force, and racial discrimination. The Washington Post’s “Fatal Force” database, covering the years 2015 through 2024, is offered as a bellwether of American progress in addressing its police abuse; and, it is observed, the nation’s yearly count of fatal police shootings of civilians has been increasing, rather than decreasing.

To help make sense of our lack of national progress, …

White Paper And Black Water: Environmental Control Of Labor In Appalachian Paper Mill Communities, Matthew C. Powell

Graduate Theses, Dissertations, and Problem Reports (ETD)

In several small Appalachian communities, the West Virginia Pulp & Paper Company dominated the local landscape. The company stripped the mountainsides of spruce trees for pulpwood and used rivers for industrial processes and waste disposal. The small towns along these rivers and between these mountains relied on paper mills for employment. Corporate control over the natural environment, and water more specifically, was a necessary requirement for paper production, but also acted as a source of power over employees and their communities. When paper workers sought to organize, the company responded by leveraging their control over the environment against them to …

This configuration effectively separated and detected diverse analytes, including β-blockers, amino acids, and …

Performance Is In The Eye Of The Beholder: Exploring The Moderating Role Of Psychological Perspective Distancing Within Thought Self-Leadership In An Organizational Context, Christopher Bryton Neck

Graduate Theses, Dissertations, and Problem Reports (ETD)

Self-leadership, or the process through which individuals perform various cognitive and behavioral strategies to attain the self-direction and self-motivation necessary to perform in desired ways, has consistently been evidenced to enhance individuals’ performance through promoting a variety of positive individual cognitions, such as self-efficacy, positive affect, and engagement and through diminishing key threatening mental states such as stress, negative affect, and dysfunctional thinking (Harari et al., 2021; Knotts et al., 2022). The cognitive component of self-leadership, thought self-leadership (TSL) has been found to be particularly impactful, aiding the individual to modify and adapt their dysfunctional thinking to be more constructive …

Financial Literacy As A Predictor For Future Financial Outcomes, Roy Baker Jr.

Graduate Theses, Dissertations, and Problem Reports (ETD)

John Adams once stated that “All the perplexities, confusions and distresses in America arise not from defects in their constitutions or confederation, not from a wont of honor or virtue, so much as from the downright ignorance of the nature of coin, credit, and circulation” (Adams, 1787). Yet the apparent lack of dedication to the financial literacy of the U.S. population seems contrary to one of our Founding Father’s sentiments. Implementation of a financial literacy curriculum at the secondary education level can be described as ad hoc at best. Using delinquency data and the financial literacy programs of all 50 …

The Effects Of Strip Clearcutting On Natural And Artificial Northern Red Oak Regeneration In A Central Appalachian Hardwood Stand, Patrick Aaron Plaugher

Graduate Theses, Dissertations, and Problem Reports (ETD)

There are well-known difficulties associated with regenerating oak stands throughout the Central Hardwoods region. To successfully regenerate oak, competitive sources of advance reproduction are required ahead of harvesting—a condition that is rarely present, especially on productive sites. While treatments that enhance seedling competitiveness (e.g., midstory removals, burning, vegetation control) are available, in practice, these are rarely implemented and/or effective because of large treatment costs and/or because they require delaying harvest.

As a potential alternative practice, we report the 10-yr results of a strip clearcut regeneration method. This method removes alternating 45-m wide strips across a mixed Appalachian hardwood …

Graduate Theses, Dissertations, and Problem Reports (ETD)

ABSTRACT

Reassessing Hourly Neurological Assessments: A Quality Improvement Initiative

Haley Lynne Johnson, BSN, RN

Background: Stroke and brain injuries remain among the leading causes of mortality in the United States, accounting for 162,890 deaths in 2021 (Centers for Disease Control and Prevention [CDC], 2021). Although frequent neurological assessments are essential for monitoring patient status, limited evidence supports the prolonged use of hourly neuro-checks (LaBuzetta et al., 2022). Excessive neuro-check frequency has been linked to sleep deprivation, an increased risk of delirium, and inefficient resource utilization (Kishore et al., 2021).

Purpose: This project aimed to assess the impact of …

Comparative Analysis Of Electrode Encapsulation Reliability: Planar Vs. Thermoformed Interdigitated Neural Electrodes In Biomedical Engineering, Tatum Peyerl

Graduate Theses, Dissertations, and Problem Reports (ETD)

Durable dielectric encapsulation is crucial for the long-term function of implantable neural electrodes; however, the reliability of curved, thermoformed coatings remains underexplored. This study addresses that gap by comparing planar (non-thermoformed) and thermoformed interdigitated neural electrodes (IDEs) encapsulated in Polyimide-2611. Both device types underwent accelerated in vitro aging in phosphate‑buffered saline (PBS) at 67 °C for approximately 91 days, simulating two years of physiological exposure. Post-accelerated aging evaluation included electrochemical impedance spectroscopy (EIS) from 0.1 Hz to 100 kHz to monitor moisture‑induced leakage, and high‑voltage breakdown testing under saline immersion to assess dielectric strength. After aging, all electrodes maintained impedance …

The Effect Of Carrier Type And Material Used On Results Of 1,1,1,2-Tetrafluoroethane Application To Teeth, Jonathon Logan Williams Dds

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: The formulation of a pulpal diagnosis is crucial to prescribe appropriate treatment recommendations for endodontics. The application of a cold stimulus to the tooth’s surface utilizing the refrigerant 1,1,1,2-Tetrafluoroethane (R-134a) is a common way to obtain a pulpal diagnosis. Cotton as a form of applicator is used to absorb the R-134a and create a temperature change in the pulp. There is limited research if there is a better material than cotton to generate this cold response. No studies to date have been found to determine if a sponge as an applicator would generate a more significant cold response than …

Individuals' Trust Of Bank Acquisitions, Christy Mccollum Knight

Graduate Theses, Dissertations, and Problem Reports (ETD)

Recent transactions within the financial services industry have seen an uptick in credit unions acquiring traditional community banks. Between the years 2020 and 2024, there were 64 announced bank mergers and acquisitions by Credit Unions, and this trend is expected to continue (S&P, 2025). As there are fundamental differences between credit unions and traditional community banks, the question arises, “How will consumer confidence and trust be affected by these mergers and acquisitions?”

This dissertation investigated how consumer trust would be affected by their propensity to trust others (Disposition to Trust), their perception of the financial services industry (Institution-Based Trust), their …

Three Essays On The Socioeconomics Of Drinking Water Pfas Contamination, Nabin Babu Khanal

Graduate Theses, Dissertations, and Problem Reports (ETD)

Per- and polyfluoroalkyl substances (PFAS) are a group of over 15,000 synthetic compounds widely used for their resistance to heat, stains, grease, and water. While central to many modern conveniences, ingestion of PFAS is increasingly linked to adverse human health outcomes and are now detected globally in drinking water systems. This dissertation investigates three interrelated aspects of PFAS contamination in U.S. drinking water: (1) socioeconomic determinants and spatial patterns of contamination; (2) the economic impacts of contamination on residential property values; and (3) the effect of inconsistent PFAS regulations on public trust in environmental governance.

Using data from the U.S. …

Raman Spectroscopy For Rapid Quantification Of Macronutrients In Heirloom Beans, K. Chandler Williams

Graduate Theses, Dissertations, and Problem Reports (ETD)

Quantification of macronutrients in food requires a large investment in facilities and instrumentation as well as ongoing expenses of labor, reagents, and hazardous waste disposal. These costs pose a significant barrier to determining macronutrient quantities in the thousands of uncharacterized landrace and heirloom crops and discourage traditional crop breeding projects from ensuring that their selected crops maintain desirable macronutrient profiles in addition to target agronomic traits. Our objective was to test whether a hand-held Raman spectrometer—a technology which has found use in plant disease diagnostics but remains largely overlooked in nutrient quantification-- could provide a feasible means for quantifying the …

Prioritizing Amd Impaired Watersheds For Watershed-Scale Restoration Using Multi-Criteria Decision Analysis, James Nicholas Marino

Graduate Theses, Dissertations, and Problem Reports (ETD)

Acid Mine Drainage (AMD) remains a significant environmental challenge in coal-mining and hard rock regions like West Virginia, degrading water quality and ecosystem health. Traditional site-specific remediation efforts often prove inefficient in addressing AMD at large scale. This study explores watershed-scale restoration as a more effective solution, leveraging centralized treatment facilities and multi-source pollution management. This study will follow Multi-criteria Decision Analysis (MCDA), specifically the Analytical Hierarchy Process (AHP), to develop a structured rubric for grading watersheds. The process involves identifying critical criteria, organizing them into a hierarchy, and generating weights for clusters of criteria through collaboration with decision makers. …

Using Visual Prompts To Analyze Ejection Fraction In Echocardiograms, Kevin Reisch

Graduate Theses, Dissertations, and Problem Reports (ETD)

Left ventricular ejection fraction (LVEF) is a critical biomarker for heart failure, but manual estimation from echocardiograms is time-consuming. Artificial intelligence can be used to accelerate this process, allowing clinicians to focus on other critical tasks. Current methods typically train models from scratch on echocardiogram datasets; however, this approach is limited by the scarcity of large medical imaging datasets, which are expensive and difficult to acquire. We present a transfer learning approach that leverages pretrained models from massive datasets, enabling continuous improvement as foundation models advance. Our method employs visual prompting to generate trainable masks for echocardiogram videos, transforming the …
