Data Augmentation And The Reliability Of Conformal Prediction For Uncertainty Quantification In Medical Imaging, Rizwan Ahamed

Graduate Theses, Dissertations, and Problem Reports (ETD)

The safe clinical deployment of deep learning models for high-stakes medical imaging tasks requires more than high average accuracy; it requires demonstrable, per-case reliability. Uncertainty quantification (UQ) provides the missing signal that tells a clinician when a model prediction can be trusted and when a case should be escalated for expert review. Among UQ approaches, conformal prediction (CP) is especially attractive because it produces prediction sets that are guaranteed, under the assumption of exchangeability, to contain the true label with a user chosen probability, and it does so without assumptions about the model or the data distribution. This report first …

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 …

Multi-Sensor Fusion For Manual Wheelchair State Estimation, Kathylee Pinnock Branford

Graduate Theses, Dissertations, and Problem Reports (ETD)

Kathylee Pinnock Branford Manual wheelchairs are essential to mobility and independence, yet accurately characterizing wheelchair motion in real-world environments remains challenging. Inertial measurement units (IMUs) provide a practical means of estimating wheelchair kinematics, but existing trajectory-reconstruction studies have largely been limited to short, controlled trials. This report developed and evaluated a four-IMU framework comprising one sensor on each rear wheel and two sensors on the wheelchair frame. Three orientation algorithms (VQF, Mahony AHRS, and Madgwick AHRS), two accelerometer ranges (±2 g and ± 4 g), and calibrated and uncalibrated sensor data were evaluated during indoor motion-capture trials and a outdoor …

Assessing Mobility And Upper Extremity Function Beyond Laboratory Settings In Manual Wheelchair Users With Spinal Cord Injury Using Inertial Measurement Units, Kathylee Pinnock Branford

Graduate Theses, Dissertations, and Problem Reports (ETD)

Manual wheelchair users with spinal cord injury (SCI) face chronic, repetitive shoulder demands that far exceed those of able-bodied daily life, placing them at high risk for rotator cuff pathology and long-term upper extremity dysfunction. Despite this burden, existing research has relied predominantly on brief laboratory assessments that capture only a narrow part of real-world mechanical demands, leaving critical gaps in the identification of true injury risk factors. This dissertation developed and applied inertial measurement unit (IMU)-based methods and novel algorithms to characterize arm use, mobility, and environmental context during a full week of free living behavior in 25 manual …

Women In Music: Experiences Of Women Oboists In Us Symphony Orchestras, Brianna Corgel

Graduate Theses, Dissertations, and Problem Reports (ETD)

The evolution of women in American music has been a gradual and ongoing process. Historically, women were largely excluded from public musical life and did not achieve widespread acceptance as professional musicians until the 20^th century, largely due to prevailing cultural and societal expectations. In the 19^th century, women typically performed in domestic settings for small gatherings of family and friends. Female instrumentalists were generally limited to the piano and a few string instruments, while wind instruments—such as the oboe—were discouraged because they were considered unladylike or visually unappealing when played. The 20^th century saw the emergence …

Effect Of Delay On Reinforcer Preference And Efficacy, Ciara Jasmine Rodriguez

Graduate Theses, Dissertations, and Problem Reports (ETD)

Behavior intervention plans are used to increase desired behavior and decrease problem behavior, and these plans require the use of effective reinforcers. High-quality reinforcers that are delivered immediately tend to be the most effective, but optimal reinforcement parameters are not always feasible or appropriate in applied settings. Some reinforcers may be disruptive, teachers’ competing responsibilities may introduce delays to reinforcer delivery, and reinforcers may not be immediately accessible. Stimuli may lose their reinforcing value with delay to their receipt, and this is referred to as delay discounting. Thus, there is likely a point where a less preferred but immediately delivered …

Dispositional Mindfulness And Autonomic Reactivity, Thomas Dylan Boyer

Graduate Theses, Dissertations, and Problem Reports (ETD)

To explain how different facets of mindfulness were associated with task performance in distinctive ways, Lindsay and Creswell (2017) proposed the Monitor and Acceptance Theory (MAT). According to this model, the mindfulness facet of monitoring present state awareness was thought to influence task performance differently than the nonjudgmental acceptance facet of mindfulness, but no studies to date have examined this model with respect to an individual's physiological response to stressful tasks. Because dispositional mindfulness has been associated with both increased and decreased physiological and affective reactions to stress in previous studies, the present study tested whether the Monitoring facet of …

Gcn5l1-Mediated Lysine Acetylation Regulates Mitochondrial Dysfunction In The Aged Heart, Jackson Edmond Stewart

Graduate Theses, Dissertations, and Problem Reports (ETD)

For over a century, cardiovascular disease (CVD) has been and remains the leading cause of death globally. CVD risk and severity increase significantly with advanced age, and mitochondrial dysfunction has been implicated in the pathogenesis of aging. Furthermore, mitochondrial health is crucial for cardiac function, as one-third of total cardiomyocyte volume is occupied by mitochondria in order to meet the high energy demand of contractile and relaxational function. It is thus crucial that we understand the pathological mechanisms driving mitochondrial dysfunction in aging and how this contributes to age-associated cardiovascular disease. The current manuscript aims to fill this knowledge gap …

Self-Leadership And Perceptions Of Artificial Intelligence: A Single-Case Study, Patrik Garren

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this single-case qualitative project is to uncover how self-leadership’s behavioral and cognitive strategies influence perceptions of Artificial Intelligence (AI) and AI adoption. While existing literature acknowledges that there is an association between self-leadership, technology’s perceived usefulness and ease of use, as well as comfort with AI preparedness and its professional impact, there is limited research on how self-leadership shapes perceptions of AI and AI adoption in real-life contexts. To fill this gap in contemporary literature, this project analyzes qualitative semi-structured interviews with 25 healthcare professionals involved in the implementation of ‘AI Model 1’ at their mid-sized United …

Bayan Abuhalimeh, D.D.S

Aim: The primary objective of this project is to measure the actual torque applied by dental providers when finger-tightening a healing abutment and assess the variability among individuals. A secondary objective is to analyze the correlation between applied torque and: provider experience level (residents, general dentist, specialist); gender; age; and, physical attributes (e.g., grip strength, hand size, and dominant hand used for tightening). The null hypothesis is that there is no difference in the mean finger-tightening …

The Effects Of Gesture And Age On Jurors’ Perceptions Of Child Witnesses, Jihan Hani Rashed

Graduate Theses, Dissertations, and Problem Reports (ETD)

Jurors’ perceptions of child witnesses can have significant influence in judicial outcomes, particularly in cases where children’s testimony is central (Goodman et al., 1997; Goodman et al., 1998; Castelli et al., 2005). The role of gesture in shaping jurors’ perceptions is underexplored. Studies highlight that gesture enhances memory recall and reduces cognitive load, making it an important component of effective communication (Goldin-Meadow et al., 2001; Hudson & Sheffield, 1998; Cook & Fenn, 2017). The present research consisted of two studies examining whether child witnesses’ use of gesture during recall of an alleged crime affected jurors’ perceptions of witness credibility and …

Trust, Literacy, And Choice: Exploring How Taxpayers Decide Between Self-Preparation And Professional Assistance, Bethany Jo Elam

Graduate Theses, Dissertations, and Problem Reports (ETD)

Each year, taxpayers must decide whether to self-prepare their tax return or hire a tax professional. While the decline in paper filing has made electronic filing the standard, the ease of access to both DIY tax software and tax professionals allows taxpayers to switch between these options each year if they wish. While previous research has focused on tangible predictors such as cost and accuracy, psychological factors, such as trust, remain largely unexplored in the modern tax-filing environment. This study investigates the relationship among perceived tax literacy among taxpayers, various dimensions of trust, and the intention to use tax software. …

Early Life Adversity And Reward Reactivity In Humans, Maria C. Potts

Graduate Theses, Dissertations, and Problem Reports (ETD)

Both animal and human research has identified early life adversity (ELA) as a prominent risk factor for substance use disorder (SUD). However, the underlying mechanisms linking ELA to SUD development remain unclear. Animal studies point to differences in reward responsiveness as the primary explanation; specifically, that ELA could lead to individual differences in the attribution of incentive salience to reward-predictive cues, or the “sign-tracking” behavioral phenotype. Sign-tracking has been linked to addiction-related behaviors in both animal and human studies, but no human studies have examined whether sign-tracking could partially explain the link between ELA and SUD. In fact, human studies …

The Effect Of Innovative Value Proposition On Buyer Reactions: The Moderating Roles Of Price Orientation And Perceived Risk, Chad Stuttz

Graduate Theses, Dissertations, and Problem Reports (ETD)

Value propositions are essential to the success of personal selling in the Business-to-Business (B2B) context. While earlier studies have offered valuable insights into the roles of value propositions in driving B2B sales, they have often regarded value propositions as uniform. In this dissertation, I argue that value propositions vary in their levels of innovativeness. The dissertation introduces the concept of innovative value proposition (IVP) and proposes that IVP indicates greater future growth potential to buyers, leading to more favorable reactions such as responsiveness and willingness to engage than less innovative ones. Additionally, the dissertation explores the moderating effects of buyer …

In addition, age and gender differences will be determined to evaluate whether there is a need to re-evaluate the accepted normative values for lips to Esthetic plane (E-plane).

Experimental Design and Methods: A cross sectional, observational study design was used. The study aim was to evaluate the perception and opinions regarding lip position and fullness of both lay people …

The Deposition, Prevalence, And Persistence Of Gunshot Residue In Standard And Less Lethal Ammunition, Liliana Claire Barbosa

Graduate Theses, Dissertations, and Problem Reports (ETD)

During the discharge of a firearm, gunshot residue (GSR) is released and settles into nearby surfaces, leaving traces that can provide valuable information for forensic investigations. This study aims to improve understanding of the deposition, prevalence, and persistence of standard and less-lethal ammunition through an analytical framework that examines collection and analysis protocols, revealing connections among multiple traces for effective use in investigations and courtroom proceedings.

Research into the chemical residues of less lethal ammunition (LLA) is a critical frontier in shooting investigations. While standard leaded ammunition has over a century of established literature, the chemical fingerprints of LLA residues …

Survival In The Stigmatized Industry (Bitcoin Atm), Brooks Mcadam

Graduate Theses, Dissertations, and Problem Reports (ETD)

ii ABSTRACT Survival in the Stigmatized Industry (Bitcoin ATM) Brooks McAdam This paper examines how companies can survive in a stigmatized industry where the same message may attract customers while simultaneously generating skepticism. The study posed the following research question using the Bitcoin ATM industry as the context: Does the message presented on company websites influence the degree of exit risk in a market characterized by moral concerns, exposure to fraud, and unstable regulation? The answer is clear. Messaging is important; however, not every message is equally important. Fee-related messaging emerged as the most consistent predictor of exit risk. Messaging …

Supply Chain Optimization For Fertilizer Production From Wastewater, Ethan Clement Robey

Graduate Theses, Dissertations, and Problem Reports (ETD)

In West Virginia, approximately 27,000 tons of wastewater solids are generated annually, with nearly 75% being landfilled or alternatively disposed of in a non-beneficial manner. Over the past two decades, the amount of these solids being taken for beneficial uses, such as agricultural application, has declined by 25%, while landfilling has increased by more than 30%. This highlights issues related to eutrophication and disposal costs. This study aims to develop a supply chain optimization framework that addresses the conversion of wastewater solids into fertilizers to match local farm requirements, while determining processing facility locations that minimize transportation costs. To determine …

Optimization Of Feed Manufacturing Productive Capacity, Feed Quality, And Feed Safety Utilizing A Variety Of Pellet Die Parameters, Feed Additives, Conditioning Specifications, And Simulated Feed Bin Storages, Lucas Edward Knarr

Graduate Theses, Dissertations, and Problem Reports (ETD)

In Chapter 2, an experiment was conducted to determine if the inclusion of 1.50% mixer-added water (MAW) and/or 0.25% Azomite^® (AZM) would be suitable in alleviating concerns regarding pellet production rate and pellet quality when manufacturing feed with low-moisture corn. Furthermore, the authors aimed to determine if these additives had varying effects when utilizing different pellet die thicknesses. A 2 (Azomite; 0.00% or 0.25%) x 2 (mixer-added water; 0.00% or 1.50%) x 3 (pellet die thickness; 32 mm, 38 mm, or 45 mm) factorial arrangement was utilized to create the twelve experimental treatments, each manufactured …

Interpersonal Dark Side Of Impostor Thoughts: Predicting Workplace Ostracism Via Surface Acting And Cognitive Dissonance, And The Moderating Role Of Self-Leadership, Asiye Zeytonli

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation investigates the "interpersonal dark side" of workplace impostor thoughts

(WIT), exploring how the internal experience of feeling like a professional fraud translates into

the social exclusion of colleagues through defensive ostracism. While prior literature has

extensively documented the intrapersonal distress associated with the impostor phenomenon,

such as anxiety and burnout this research addresses a critical gap by examining how these

internal states drive behaviors that harm the organizational social fabric. Drawing upon an

integration of Conservation of Resources (COR) theory and Cognitive Dissonance Theory

(CDT), I propose and test a dual-pathway model. The first pathway (COR) suggests that …

Divided Loyalties: Military Recruitment And Emancipation In Kentucky, Jacob Joseph Klinger

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation explores how Unionist Kentuckians leveraged their military recruitment to negotiate the scope of federal emancipation during the American Civil War. By 1863, the War Department’s need for troops superseded the racial sensitivities of inhabitants in loyal slave states like Kentucky by promising to free and enlist Black men if white recruits failed to fill the quota. Kentucky’s proslavery Unionists responded and white volunteerism surged by 23 percent, 10 percent more than the national average, to fill the quota and negate military emancipation. Kentucky leaders heralded the recruiting effort but struggled to sustain it alongside an uncredited militia which …

Understanding Housing Market Adjustment: Evidence From Population Shocks, Regulation, And Monetary Policy, Michael Tyler Duncan

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation studies how housing markets adjust to demographic shocks, local regulation, and macroeconomic policy through three related essays. Chapter 1 develops a dynamic stochastic general equilibrium (DSGE) model and panel VECM evidence to study how population volatility affects housing prices, rents, and construction. It finds that population shocks generate strong price responses across housing markets and more pronounced effects in tight housing markets and declining regions. Chapter 2 examines local rental registry policies using county-level difference-in-differences analysis and finds limited aggregate effects but meaningful heterogeneity across treatment intensity and market segments. Chapter 3 revisits the macro-housing VAR literature on …

Taxpayers Willingness To Use Ai Conversational Tools, Nessrine Mesto-Assaad

Graduate Theses, Dissertations, and Problem Reports (ETD)

With the rapid emergence of Artificial Intelligence Conversational Tools (AICTs), such as ChatGPT and Google Gemini, and their widespread use, the need to understand users’ acceptance of this emerging technology has increased. Prior research has investigated users’ acceptance of AICTs in hospitality, tourism, e-commerce, and retail industries. However, users’ acceptance of the use of AICTs for tax information remains relatively underexplored in the tax context. Therefore, this study investigates taxpayers’ willingness to accept and use AICTs for tax-related questions when e-filing their tax returns. Drawing on the Artificial Intelligence Device Use and Acceptance (AIDUA) model as a research framework, this …

Assessment Of Countermovement Jump In Athlete Status And Monitoring, Michael David Delong

Graduate Theses, Dissertations, and Problem Reports (ETD)

Utilizing a CMJ to test athlete physical abilities and training program efficacy is popular, as it is simple, noninvasive, and has significant relations with sport qualities. However, assessments often use discrete outcome measures. This research explored strategy-based measures accounting for eccentric power and time and may explain athlete status more effectively. The research objectives are to analyze the use of the mean power rate of the CMJ to compare athletes' playing ability and its usefulness in monitoring during off-season training. Additionally, power-time curve analysis added location and timing of effects due to fatigue or fitness adaptation. Proper testing and monitoring …

A Constraint-Based Approach To Developing Melodic Improvisational Skills In Intermediate Jazz Piano Students, Alton Xian Rong Wong

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examines the pedagogical value of a constraint-based approach in helping students develop improvisational fluency and coherence by facilitating audiation. Although there are pedagogical texts on jazz improvisation that incorporate exercises shaped by constraint-based thinking, there is neither a systematic framework for their application with students of varying levels and musical backgrounds, nor a clear explanation of their pedagogical purpose. This research investigates how constraint-based pedagogy, through the lens of rhythmic, harmonic, and melodic parameters, can be applied independently or collectively to support the development of improvisational fluency in intermediate level jazz piano improvisers. It argues that musical constraints …

Adventures In Black Hole Binary Waveform Modeling, Siddharth Mahesh

Graduate Theses, Dissertations, and Problem Reports (ETD)

The modeling of black hole binaries requires accurate descriptions of both their relativistic vacuum dynamics and their interaction with surrounding astrophysical environments. Although these problems are often treated separately, this dissertation develops a unified view: key observables of black hole binary systems can be understood by identifying the dynamical instabilities that control their evolution. In the vacuum problem, the relevant unstable structure is associated with the remnant spacetime and its role in shaping the merger-ringdown gravitational waveform. In the environmental problem, the relevant instability is the epicyclic instability of orbits in the binary potential, which controls the location and evolution …

Be A Man: Hypermasculinity And Hostile Attribution Bias As Predictors Of Violence, Kaley Nicole Potter

Graduate Theses, Dissertations, and Problem Reports (ETD)

In recent years, violence has risen to record-high numbers in communities and correctional facilities, with men perpetrating the vast majority of violent crimes. Hypermasculine values (e.g., power, aggression, and domination) have been linked to aggressive and violent behavior. Hostile attribution bias, which leads individuals to attribute hostile intent to neutral or ambiguous stimuli, has also been linked to aggression.

The current study used structural equation modeling (SEM) to examine hypermasculinity and hostile attribution bias as predictors of proclivity for violence, comprised of aggression and historical violence. The model was iteratively modified to assess changes in model fit and constructs. Male …
