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 …

Examining Moral Susceptibility In Ai Vs. Human-Assisted Decision-Making, Seth James Fogle

Graduate Theses, Dissertations, and Problem Reports (ETD)

Artificial intelligence (AI) systems are increasingly integrated into decision-making contexts, yet their influence on ethical judgment remains unclear. This study examines whether advice from an AI advisor, compared to a human advisor, affects moral susceptibility in a consumer decision-making scenario. Using a 2 × 2 between-subjects experimental design (advisor type × price condition), this research tests whether personal agency, perceived objectivity, and diffusion of responsibility operate as psychological mechanisms underlying ethical decision-making.

Results indicate that advisor type did not significantly influence moral susceptibility, nor did it significantly affect the proposed mediators. Additionally, the price condition did not moderate these relationships. …

ABSTRACT

Social Media Addiction and its Influence on the Physical Social Interactions Among West Virginia University Students

Blessing O. Omaleko

This qualitative study investigated social media addiction and its perceived influence on face-to-face interactions among 14 West Virginia University students using an open-ended qualitative survey. Grounded in Griffiths' (2013) behavioral addiction components, salience, mood modification, conflict, and relapse, the data were analyzed using Thematic Analysis (Braun & Clarke, 2006). Findings revealed that while students characterized their social media use as a habit rather than an addiction, their descriptions aligned with multiple addiction components. Students consistently valued in-person interactions over online …

Deposition And Diagenesis Of Permo-Triassic Gypsum From Wyoming And Texas: Saline Lake And Groundwater Systems Of Equatorial Pangea, Maya Yamei Bradford

Graduate Theses, Dissertations, and Problem Reports (ETD)

Knowledge of gypsum textures and the processes that yield them is important for interpreting the history of environments, climates, and life on Earth. This is because gypsum textures are products of specific environmental, microbiological, and diagenetic processes, and because gypsum is relatively common in the Earth’s sedimentary record. Despite this significance, gypsum is relatively understudied. The fundamental goal of this dissertation is to advance our understanding of gypsum textures by presenting detailed, petrography-based investigations of Permo-Triassic gypsum from the continental interior of Pangea.

Gypsum is typical in the Permo-Triassic sedimentary record of tropical Pangea, where it is associated with red …

Borrowed But Mine: Time-Based Asymmetries In Psychological Ownership, Elizabeth Ann Brauer

Graduate Theses, Dissertations, and Problem Reports (ETD)

People often borrow everyday items, such as a friend’s jacket or pair of sunglasses, and after a period of use, may begin to feel as if the item is their own. Psychological ownership captures this felt sense of “mine,” even in the absence of legal ownership, and reflects the extent to which a target becomes incorporated into the self (Pierce et al., 2003). Despite decades of work on psychological ownership, little is known about how psychological ownership develops and changes within interpersonal lending and borrowing contexts. This dissertation examines how possession duration influences psychological ownership in interpersonal borrowing relationships and …

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 …

Phylogeography, Fungal Host Specificity, And Fitness In The Corallorhiza Maculata Species Complex, Hana Thixton-Nolan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mycoheterotrophic plants exploit fungi for most or all nutritional needs, providing a compelling system to address the evolutionary consequences of genome reduction, population-level variation, and germination requirements. I am using the widespread Corallorhiza maculata species complex to address questions of genomic variation, fungal host specificity, morphological variation, and germination requirements across the broad geographic range from Mexico to northern North America. This complex contains C. bulbosa, C. macrantha, and C. mertensiana, the latter with three varieties (maculata, occidentalis, and mexicana). These taxa vary in flowering time, floral morphology, and fungal associations. However, the degree …

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 …

Feasibility Study Of Concurrent Removal Of Organics And Ammonium Using An Iron Dosed Upflow Anaerobic Sludge-Blanket Bioreactor, Morgan Elizabeth Amos

Graduate Theses, Dissertations, and Problem Reports (ETD)

Aerobic microbial reactions have commonly been utilized in treatment processes to oxidize and remove organics and nitrogen through aeration, using processes such as nitrification that converts ammonium (NH₄⁺) into nitrite (NO₂^-) and nitrate (NO₃^-). Anoxic microbial reactions like denitrification often require organic compounds as an external source to chemically reduce the oxidized nitrogen (NO₃^- and NO₂^-) to nitrogen gas (N₂) for nitrogen removal from the liquid phase. These mainstream processes have a high chemical cost and energy footprint which results in an increased release …

Framing Addiction In The Age Of Vaping: A Journalism-Focused Reporting Toolkit, Jessica L. Riley

Graduate Theses, Dissertations, and Problem Reports (ETD)

This project addresses a critical gap in journalism practice: the lack of accessible, evidence-based guidance for reporting on addiction. Particularly as it relates to nicotine, tobacco and vaping. Journalists play a key role in shaping public understanding of substance use, yet existing resources often focus on opioids, lack specificity, or fail to keep pace with rapidly evolving nicotine products and scientific research. As a result, reporters may struggle with inconsistent terminology, unclear risk communication and the potential for unintentionally stigmatizing language.

Grounded in media effects theory, health communication and stigma research, this project examines how journalistic language and framing influence …

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 …

Multi-Omics Analysis Of Immune-Metabolic Adaptation To Direct-Fed Microbial Supplementation In Newly Weaned Beef Steers, Adekunle Odunayo Ajiboye

Graduate Theses, Dissertations, and Problem Reports (ETD)

Immune and metabolic disruption during weaning represents a major challenge to health and productivity in beef cattle. This dissertation tested the hypothesis that supplementation with multi-strain direct-fed microbials (DFMs) modulates immune regulation and metabolic pathways associated with adaptation to weaning stress. To address this, whole-blood transcriptomics and plasma metabolomics were used to evaluate molecular and metabolic responses in newly weaned beef steers during the receiving period. Transcriptomic analysis identified differential expressions of genes associated with immune signaling and inflammatory regulation, indicating modulation of immune-related pathways without changes in growth performance. Metabolomic analysis revealed alterations in circulating metabolites related to amino …

Climate change has been identified as one of the greatest threats to global biota in recorded human history. Consequences are expected to be more pronounced in ectotherms because most of their physiology is controlled by external temperature conditions. Predicting how ectotherms may respond to increasing global temperatures necessitates information about thermal limits of thermal sensitive species and how increasing temperatures may affect individual and population-level fitness. Therefore, the objectives of this research were aimed at gaining a better understanding of the mechanisms that underpin thermal tolerance limits of fish and how those mechanisms may affect fitness and population persistence under …

Essays On Stock Market Expectations And Financial Decisions, Shanxiang Yang

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation consists of three essays on stock market expectations and financial decisions. The first essay shows significant racial differences in expectations regarding future stock market performance. Using data from the Federal Reserve Bank of New York’s Survey of Consumer Expectations from 2013 to 2022, we find that, relative to White Americans, Black and Hispanic Americans have lower probabilistic expectations that the stock market will increase. This racial gap in expectations was even larger during the recession caused by the Covid-19 epidemic, suggesting that economic uncertainty exacerbates this heterogeneity in expectations. Furthermore, we show that relative to White Americans, the …

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 …

Development Of An Adhesive Emulsion Hydrogel For Soft Tissue Reconstruction, David J. Alpert

Dissertations and Theses

Soft tissue filling materials are most commonly associated with various aesthetic, cosmetic procedures, primarily using lightly cross-linked hyaluronic acid to fill wrinkles and give facial features a more youthful appearance. These natural materials are biocompatible but degrade over time while more persistent synthetic fillers may provoke a chronic inflammatory response. Migration from the injection site is also a key factor as this may not only render the implant non- functional but necessitate further procedures for removal of the foreign material. Such concerns are more pronounced for soft tissue reconstruction procedures (e.g., to treat congenital defects or traumatic injuries), which require …
