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

Evaluation of Finger-Tightening Torque Applied to Implant Healing Abutments by Dental Providers with Varying Experience and Physical Characteristics: An In-vitro Study
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
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
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
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 …

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
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
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
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
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
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
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
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 …

Development Of Hydrogen Emissions Quantification Systems To Expand Understanding Of Leaks And Losses Associated With The Burgeoning Hydrogen Transportation Sector, Christopher Loomis
Development Of Hydrogen Emissions Quantification Systems To Expand Understanding Of Leaks And Losses Associated With The Burgeoning Hydrogen Transportation Sector, Christopher Loomis
Graduate Theses, Dissertations, and Problem Reports (ETD)
To combat global warming, alternative fuels are being investigated. Hydrogen is at the forefront of this movement, advertised as having zero emissions due to the products of the energy reaction being only water. However, studies over recent decades indicate that hydrogen in the atmosphere acts as a form of greenhouse gas (GHG) by increasing the lifespan of methane in the atmosphere. Models are attempting to estimate the possible effects of a transition to a hydrogen-fueled economy but lack empirical data to provide confidence to these estimated values. There is little data that quantifies hydrogen from anthropogenic sources.
To address this …

Applied poultry nutrition and feed manufacture science can be described as a “three-legged stool” supported by pellet quality, feed hygienics, and nutrient availability, where imbalance in any one component can compromise overall bird performance. The research presented herein primarily addresses feed hygienics and nutrient availability, with pellet quality serving as an underlying theme, to better understand how processing conditions and dietary formulation influence performance and nutrient utilization.
In Chapter 2, the objective of this study was to evaluate the effects of hygienizer retention time on bacterial reduction during feed manufacture using Enterococcus faecium as a Salmonella surrogate. Pellet mill motor …
White Lies Of Time: Temporal Racialization In 19th-20th Century American Literature, Yu Uchida
White Lies Of Time: Temporal Racialization In 19th-20th Century American Literature, Yu Uchida
Graduate Theses, Dissertations, and Problem Reports (ETD)
By examining mid-nineteenth to mid-twentieth century American literary texts, this dissertation project aims to theorize the ways in which whiteness relies on conceptualizations of time to hegemonize non-white subjects and prescribe their historical representations. Because whiteness is dynamic in its emergence and effects and ubiquitous in sociopolitical and cultural realms, this dissertation holistically turns to white, Black, and Indigenous writers to delineate how whiteness functions throughout the period and how racialized subjects negotiate it. Portraying the nation’s history as lived experience rather than objectified knowledge, the racialized authors I examine undermine the concept of linear progressive time that subtends structural …
Three Essays On Option Markets, Fangzheng Ou
Three Essays On Option Markets, Fangzheng Ou
Graduate Theses, Dissertations, and Problem Reports (ETD)
This dissertation includes three essays examining index option and stock option markets. The first essay investigates the pricing kernel puzzle by examining S&P 500 index option returns and empirical pricing kernels across expiration dates ranging from one month to one year. We document that at short maturities, out-of-the-money call option returns are negative and decrease with the strike price, while at long maturities, at least some are positive and increase with the strike price. Empirical pricing kernels predominantly exhibit a W-shape at short maturities, with this pattern becoming less pronounced and evolving toward a monotonically decreasing curve at longer maturities. …
High-Resolution Laser Diagnostics For Ion Measurements In Magnetized Plasmas, Katey Stevenson
High-Resolution Laser Diagnostics For Ion Measurements In Magnetized Plasmas, Katey Stevenson
Graduate Theses, Dissertations, and Problem Reports (ETD)
In this work, we investigate ion heating in two plasma systems (helicon plasmas and flux rope plasmas) using the PHAse Space MApping (PHASMA) experiment. Our studies rely on high-resolution laser diagnostics, specifically laser-induced fluorescence (LIF), to measure ion velocity distribution functions (IVDFs). The temperature and bulk flow of each species are inferred from their respective VDFs. This dissertation is organized into three main parts: the study of ion heating in helicon plasmas, pulsed LIF modeling and diagnostic development, and the study of ion heating in flux rope plasmas. Helicon plasma sources efficiently generate high-density plasmas and are widely used to …
