Sedimentological And Geochemical Investigation Of The Origin Of Upper Pennsylvanian Black Shales, East-Central Appalachian Basin, Tyler Hickey

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the east-central Allegheny foreland basin, laminated black shales overlying Upper Pennsylvanian Glenshaw Fm. coal seams record paleoenvironmental conditions associated with the termination of peat swamp deposition before, during, and after the Carboniferous Coal Forest Collapse (CCFC), a major paleobotanical evolutionary event during the Late Paleozoic Ice Age (LPIA) that contributed to extinction of lepidodendrons near the Desmoinesian-Missourian boundary (~306 Ma). Previous investigations of the CCFC commonly implicate an episode of aridification during intensification of LPIA glaciation that stressed the lepidodendrons beyond their ecological tipping point; however, the cause of this aridification is unclear. An investigation of Glenshaw Fm. black …

Exploring The Determinants And The Effects Of Crypto Assets, Qiu Zheng

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation consists of three studies that primarily delve into the factors influencing and outcomes of firms’ crypto assets. The first paper examines the association between corporate crypto assets and firms’ credit ratings. Using a large sample of U.S. public firms, we find that firms holding crypto assets receive significantly better future credit ratings, particularly when their activities are related to crypto mining, which generates relatively stable cash flows. However, crypto exposure also increases disagreement among credit rating agencies, reflecting the uncertainty associated with evaluating crypto-related risks. This effect is more pronounced when firms operate in less transparent information environments …

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 …

The Dual-Factor Model (Dfm) Of Mental Among Appalachian Youth, Mawyah Adel Bashatah

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background. Adolescent mental health is a critical public health concern, particularly in rural Appalachian communities where rates of depression, anxiety, and substance use exceed national averages and access to mental health resources remain severely limited. Traditional mental health frameworks rely predominantly on the identification and reduction of psychopathological symptoms, neglecting the independent contributions of positive well-being to adolescent risk and resilience. The Dual-Factor Model (DFM) of mental health offers a more comprehensive alternative by simultaneously assessing subjective well-being (SWB) and psychopathology, classifying individuals into four distinct groups: Complete mental health, Vulnerable, Symptomatic but content, and Troubled. Despite the DFM’s growing …

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 …

The Impact Of Caregiver Training And Education On Confidence And Perceived Competence In Facilitating Self-Care Skills In Children, Ryan M. Coen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Caregivers, especially those residing in rural Appalachia, face significant barriers and hardships that can hinder their ability to promote ADL, IADL, and self-care skill development. These barriers faced include geographic isolation, socioeconomic barriers, and a high prevalence of disabilities. Many caregivers may struggle to facilitate these self-care skills competently and effectively, and a gap is present in the most effective means to teach caregivers in this region the necessary skills.

Effects Of Fluency-Based And Percentage-Based Mastery Criteria On Learning, Maintenance, Application, And Learner Experience In Behavior-Analytic Skill Acquisition, Marisela Alicia Aguilar

Graduate Theses, Dissertations, and Problem Reports (ETD)

In behavior analysis, staff are often trained to percentage-based criteria to demonstrate that they have mastered a skill. However, percentage-based mastery criteria may not result in long-term maintenance of the skill. In other areas of instruction, fluency criteria resulted in multiple positive outcomes such as maintenance, endurance, and application of the skill beyond the training context, but these outcomes have not yet been widely demonstrated in the context of teaching behavior support plan (BSP) content and implementation. Across two experiments, we attempted to evaluate the extent to which training individuals to a fluency-based or percentage-based criterion resulted in maintenance and …

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 …

Operationalizations Of Adverse Childhood Experiences And Health Prediction, Sarah Josephine Miller

Graduate Theses, Dissertations, and Problem Reports (ETD)

Exposure to adverse childhood experiences (ACEs) has been consistently linked to suboptimal health outcomes and behaviors across the lifespan. As such, there has been widespread adoption of measures like the 10-item cumulative ACEs count measure developed by Felitti and colleagues (1998) across research literature and clinical practice. However, this measure was not developed with consideration of optimal psychometric properties and thus consists of several limitations that inhibit understanding of the specific dimensions of adversity that influence health outcomes. This 3-study dissertation focused on different measurement and statistical techniques to better understand the associations between ACEs and health. In study 1, …

Upper Echelons And Corporate Venture Capital: Ceo Effects On Investment Direction And Resource Deployment, Ralph Judicael Mompoint

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examines how founder-CEO status shapes the strategic orientation of corporate venture capital (CVC) activity. Drawing on upper echelons theory, I argue that founder-CEOs differ from non-founder CEOs in where they direct CVC investments, not simply in whether they engage in CVC at all. Using a panel of S&P 500 firms spanning 2004 through 2024, I test whether founder-CEOs pursue greater CVC activity overall and whether they concentrate that activity in ventures operating within the firm's core industry. Results from random-effects negative binomial regression models show that founder-CEO status is positively associated with core-industry CVC but not with investments …

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 …

Government Financial Statements: The Influence Of Audit Opinion Type On Attitudes Toward Taxation, Stephanie Ann Vonfintel

Graduate Theses, Dissertations, and Problem Reports (ETD)

The United States government has a responsibility to American citizens to be a good financial steward of their tax dollars. The inability to fulfill this responsibility is evidenced by 28 consecutive years of audit failures, whereby the Government Accountability Office has been unable to issue an opinion on the United States government’s annual financial statements. An experiment varying audit opinion type is used to evaluate whether the United States government failing (or passing) its annual financial statement audits influences attitudes toward federal taxation. Findings show support for federal taxation is strongest when citizens are told that the United States government …

To achieve this goal, several studies were undertaken to develop and optimize an AD system to use ceramic inks. A 130 kHz AD system was developed with 4 material pumps to allow for depositions of individual compositions of the in-situ mixture of multiple solutions to allow for the fabrication of functional gradients in three dimensions. This system was then programmed to deposit air electrode layers containing different material ratios and porous microstructures, comparing their electrochemical performance to …

Success Coaching And Conditional Admit Student Success, Zachery Oliver Thayer

Graduate Theses, Dissertations, and Problem Reports (ETD)

Student success is a matter of critical importance to institutions of higher education, and to students. Colleges and universities exist in a current context of decreasing supply of potential students as a result of an impending demographic cliff and, therefore, increased competition for those remaining students, all while many institutions have become more tuition-dependent. This creates an incentive to decrease selectivity in order to meet enrollment goals as well as to focus university resources on student success measures that impact retention.  Some institutions have decreased selectivity to the point of admitting students conditionally or provisionally, even if those students do …
