A regression-based mediation analysis was performed using the Hayes’ (2013) macro to test the indirect effect of mentor support on interest through university sense of belonging. Consistent with our hypothesis, the analysis revealed a statistically significant and positive indirect effect of …

A Critical Assessment On The Resources And Extraction Of Rare Earth Elements From Acid Mine Drainage, Christopher R. Vass

Graduate Theses, Dissertations, and Problem Reports (ETD)

Rare earth elements (REEs) are crucial to many modern products used in both civilian and defense applications. Currently, a reliable supply of these elements is uncertain with the clear majority of REE production and refining occurring predominately in China. Furthermore, domestic ore deposits with commercially attractive concentrations of REEs are uncommon in the United States. As a result, the identification of a domestic supply of these technology metals is essential not only for manufacturing consumer merchandise but also for national security. Recently, one promising source of REEs has been identified: coal and coal-byproducts. One of those is acid mine drainage …

Health Literacy And Family Factors In The Transition To Adult Care In Adolescents With Type I Diabetes, Ellen M. Manegold

Graduate Theses, Dissertations, and Problem Reports (ETD)

Successful management of type 1 diabetes (T1DM) in adolescence involves multiple daily tasks, developmental changes, and the expectation of transition to an adult provider. Health literacy is one variable to consider in the context of transition, as studies have demonstrated the correlation of parental health literacy with health behaviors and outcomes, yet not studied adolescent health literacy in T1DM. Family factors (e.g., management responsibility, diabetes-specific family conflict, parental support) also are important to behavior and health outcomes in adolescents with T1DM. Study aims were to: 1) examine the association of adolescent health literacy to transition readiness and health outcome in …

Stockmanship Education And Evaluation, John K. Yost

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation documents two separate works. The first is an evaluation of WVU SFMS/SOIDC Large Animal Module and the second is the development and use of the Stockman’s Scorecard. The WVU SFMS/SOIDC Large Animal Module provides foundational information on food animal husbandry and veterinary procedures to SOF Combat Medic candidates. A quasi-experimental design was used to determine if the module content resulted in an increase in food animal production knowledge for the participants. Seventy-five percent of the subjects had no previous livestock exposure and only seven percent had previously participated in 4-H or FFA. Matched pair analysis determined that the …

A Coordination-Based Approach To Subnational Variations In Split-Ticket Voting: The Case Of Ghana 1996-2016, Samuel Kofi Darkwa

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation seeks to explain the causes of split-ticket voting (skirt and blouse voting) in emerging democracies like Ghana. The analysis carried out here has been approached at three levels. This is because voters’ decisions in the voting booth are affected by factors within the larger political environment which are often beyond the individual voter. Thus, the three approaches employed here consider individual-level, constituency-level, and elite-level factors that affect the phenomenon. In each case different datasets were used to examine split-ticket voting. The analysis reveals that the individual-level factors (demographic characteristics and political information variables) are weak in explaining ticket …

The purpose of this study is to examine the changes in the politics of health policy which opened the door to women’s health care as an important feature of health politics. Thus, my research is motivated by three …

Investigation Of Bovine Conceptus Galectins And The Effect Of Bovine Conceptus Secretory Proteins On The Endometrial Epithelial Transcriptome, Heather Lynn Baldwin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Pregnancy loss in cattle is greatest in the first 30 days of gestation. Near d15 of gestation, bovine conceptuses elongate and express LGALS1, an immunosuppressive glycan-binding protein believed to be essential for implantation. However, other members of the bovine galectin family, including LGALS3, LGALS4, LGALS7, LGALS8, LGALS9 and a galectin-13-like gene (LGALS13L), also may be expressed by the elongating conceptus. Therefore, galectin expression in elongating, d16 bovine conceptuses and intercaruncular endometrium as well as elongating, d14 ovine conceptuses and intercaruncular endometrium was assessed by RT-qPCR. Angus heifer and Texel ewes underwent estrous cycle synchronization and either inseminated or not bred. …

Automatic Detection Of Insecure Codes In Stack Overflow, Shifu Hou

Graduate Theses, Dissertations, and Problem Reports (ETD)

As the popularity of modern social coding paradigm such as Stack Overflow grows, its potential security risks increase as well (e.g., insecure codes could be easily embedded and distributed). To address this largely overlooked issue, we bring a new insight to exploit social coding properties in addition to code content for automatic detection of insecure code snippets in Stack Overflow. To determine if the given code snippets are insecure, we not only analyze the code content, but also utilize various kinds of relations among users, badges, questions, answers, code snippets and keywords in Stack Overflow. To model the rich semantic …

Henosis Experience In Gaming: A Metric For Adjustments To Global Schema And Appraised Meaning, Evan Robert Watts

Graduate Theses, Dissertations, and Problem Reports (ETD)

Meaningfulness is a media gratification distinct from enjoyment characterized by feelings of insight, contemplation, and poignancy. Video games, too, can elicit experiences of meaningfulness, but the mechanisms underlying meaningfulness are unclear and in need of further exploration. Adapting work from existential psychology, this research proposes the construct of henosis as one mechanism that might contribute to meaningful video game experiences. Henosis is a response to experiences in which a person’s fundamental schema about the world (global schema) is challenged by an event which contradicts this schema. Henosis describes the process by which this discrepancy is resolved via either reappraising the …

Trustworthiness And Stability In Same And Different Sex Relationships: Heterosexuals’ Attitudes Toward Bisexuality, Jeneice Shaw

Graduate Theses, Dissertations, and Problem Reports (ETD)

Although bisexuals are reportedly the largest sexual orientation minority group in North America (Copen, Chandra, & Febo-Vazquez, 2016), there is scant research examining the population without also including lesbian women and gay men. However, according to the American Psychological Association’s (2012) Guidelines for Psychological Practice with Lesbian, Gay, and Bisexual Clients, psychologists should endeavor to understand the unique experiences of the bisexual population. Bisexual individuals face different stereotypes, conflict within the LGB community, and different life experiences related to other sexual orientations (Rust, 2000). Two unique stereotypes applied to the bisexual community are that bisexuality is an unstable sexual orientation …

Measuring The Effects Of Interpretive Journalism On Trust And Credibility Perceptions In The Context Of Political News Coverage, Scott William Siker

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examines the effects of interpretive journalism on trust and credibility perceptions. Specifically, this study investigates interpretive journalism in the context of political news coverage and also examines the relationship between political ideology and the aforementioned variables. This study uses a 2 (interpretive journalism; fact-based journalism) x 2 (political ideology: conservative leaning; liberal leaning) between-subjects online experiment to test the proposed hypotheses. Findings illustrate the predictive value of credibility to trust within the context of political news coverage. Additionally, this study shows that individuals exhibit higher perceptions of trust and credibility towards fact-based political coverage as opposed to interpretive …

A Video Decision Aid To Influence Advance Care Planning, Angela Petry

Graduate Theses, Dissertations, and Problem Reports (ETD)

The best mechanism to achieve successful advance care planning has yet to be identified. A randomized, controlled, experimental study was performed with a sample of 54 men and women who met inclusion criteria and were randomized into the intervention versus the control group in an outpatient clinical setting in rural West Virginia (WV) from December 2018 to March 2019. Participant mean age was 72.4 years. For those who chose to participate (n=42), the intervention group received the usual standard of care, which was a face to face advance care planning (ACP) discussion with the new intervention of a video decision …

Character Morality, Enjoyment, And Appreciation: A Replication Of Eden, Daalmans, And Johnson (2017), Koji Yoshimura

Graduate Theses, Dissertations, and Problem Reports (ETD)

Much research on media entertainment seeks to explain why viewers enjoy and appreciate a variety of media content. Affective disposition theory suggests that media enjoyment results from perceptions of the morality of characters and viewers’ expectations for characters’ narrative outcomes. However, research has struggled to explain how characters with varying morality (i.e., not perfectly good or bad) entertain viewers. This study replicates a previous study conducted by Eden, Daalmans, and Johnson (2017) that investigated different types of morally ambiguous characters, using a typology of character types based on an online, collaboratively sourced typology.

Like the original study, this study found …

Psychological Trauma And Resilience Of Police Officers Involved In An Ambush: An Exploratory Study, Erin A. Teaff

Graduate Theses, Dissertations, and Problem Reports (ETD)

Law enforcement officers are widely recognized as having one of the most dangerous and stressful occupations, which can lead to lasting physical and psychological impacts. While research has examined the psychological trauma and resilience experienced by police officers, there have been very few research studies involving ambushes. Due to the continued risk of ambushes on police officers, gaining insight into the trauma and resilience of officers during these types of situations would be beneficial in providing psychologists with information to aid in their treatment officers involved in an ambush and similar unprovoked attacks. The primary aim of this study was …

Performance Study Of An Unconventional Breathresponse Papr Against A N95 Ffr And Conventional Paprs, Huihui Yang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Healthcare workers (HCWs) are the first responders when infectious pathogens occur. Powered air-purifying respirators (PAPRs) are one of the most widely used personal protective equipment for healthcare workers. Currently, few studies have been performed with HCWs in the actual healthcare work environments to assess discomforts, acceptance and protective efficiency towards wearing and use of PAPRs. The main purpose of this dissertation was to introduce and assess a brand new unconventional PAPR (Koken breath-response PAPR). The protection performance and user preferance of this unconventional PAPR were studided and compared to that of a N95 FFR and traditional PAPRs.

Firstly, a laboratory …

Student-Instructor Out-Of-Class Communication: A Media Multiplexity Approach, Cathlin V. Clark-Gordon

Graduate Theses, Dissertations, and Problem Reports (ETD)

The present set of studies examined media multiplexity theory (MMT; Haythornthwaite, 2005) in the context of student-instructor out-of-class communication (OCC) in two samples: undergraduate and graduate students. It was predicted that student-instructor tie strength (closeness) would lead to a greater number of modes used for OCC, and subsequently, the number of modes used for OCC would predict positive classroom outcomes, including communication satisfaction, cognitive and affective learning, and motivation. It was also predicted that the effect of closeness on the number of modes used for OCC would be moderated by student’s enjoyment of online communication, insofar as it would suppress …

Optimization Of Engineered Super Donor Strains Of Cryphonectria Parasitica To Reduce Canker Expansion In A Forest Setting, Amy Michelle Metheny

Graduate Theses, Dissertations, and Problem Reports (ETD)

Chestnut blight, caused by the non-native fungus Cryphonectria parasitica, has decimated American chestnut (Castanea dentata) populations throughout the eastern U.S. over the last century. Biological control of blight, termed hypovirulence, has emerged naturally in the form of a debilitating hypovirus transmitted through hyphal anastomosis among vegetatively compatible C. parasitica strains. Six unlinked vegetative incompatibility (vic) loci regulate hyphal anastomosis and thus, hypovirus transmission, which has limited biocontrol efficacy in genotypically diverse communities. Recently, four of six vic loci have been disrupted to engineer two “super donor” or SD strains. In combining these strains, enhanced transmission …

Confirmation Of Data-Driven Reservoir Modeling Using Numerical Reservoir Simulation, Al Hasan Mohamed Al Haifi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Data driven reservoir modeling, also known as Top-Down Model (TDM), is an alternative to the traditional numerical reservoir simulation technique. Data driven reservoir modeling is a new technology that uses artificial intelligence and machine learning to build full-field reservoir models using field measurements (data - facts) instead of mathematical formulations that represent our current understanding of the physics of the fluid flow through porous media. TDM combines all field measurements into a comprehensive reservoir model to predict the production from each well in a field with multiple wells.

There are many opinions, speculations and criticism about not using the physics-based …

Impact Of Implementing A Dedicated Outdoor Air System In Parallel With A Multi-Zone Variable-Air Volume System On Energy Consumption, Thermal Comfort, And Life Cycle Cost, Khaled Alghamdi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Heating, Ventilating, and Air-Conditioning systems (HVAC) consume more than 40% of energy in commercial buildings, according to the Commercial Building Energy Consumption Survey in 2012. Therefore, efforts to reduce HVAC energy consumption would be significant in coping with energy-related issues. In that context and in order to enhance the indoor air quality without compromising for energy consumption, the concept of Dedicated Outdoor Air systems (DOAS) emerged.

The literature shows that the integration of DOAS with other HVAC systems has been studied widely, yet the impact of integrating DOAS in parallel with multi-zone Variable-Air Volume systems (multi-zone VAV) for an application …

State Counter-Insurgency And Political Policing In Colonial And Post-Colonial Malawi, 1891-1994, Paul Brenard Chiudza Banda

Graduate Theses, Dissertations, and Problem Reports (ETD)

This is a study that adopts the longue durée historical approach to analyze the main causes behind the rise of ‘insurgencies’ or the so-called resistance against the colonial and post-colonial state in the present-day southern African country called Malawi from 1891 to 1994. In turn, it also uses the concept of ‘counter-insurgency’ to analyze the various measures the states in question used to defeat the ‘insurgents’. To arrive at the conclusions made in the study, I have migrated through various domestic and transnational spaces, personalities, and documents that inform the current study. I also adopt two main historical approaches to …

Glial Cell Expansion And Intercellular Signaling In The Developing Medial Nucleus Of The Trapezoid Body (Mntb), Ashley N. Brandebura

Graduate Theses, Dissertations, and Problem Reports (ETD)

Neural circuit formation is a complex process involving coordinated communication between neurons, glia and vascular-associated cells (VACs). Each cell type is responsible for a unique transcriptional and translational contribution to tissue maturation. Deciphering the intercellular signaling patterns which guide neural circuit formation during normal development is thus an essential step in understanding which components of neural circuit formation go awry in neurodevelopmental disorders. The medial nucleus of the trapezoid body (MNTB), located in the auditory brainstem, was used as a model system to study the dynamics of neural circuit formation because it contains a mostly homogeneous population of postsynaptic neurons …

Stigma, Attitudes, And Intentions To Seek Mental Health Services In College Student-Athletes, Robert C. Hilliard M.S.

Graduate Theses, Dissertations, and Problem Reports (ETD)

Previous researchers have found several factors that act as barriers to college student-athletes seeking mental health services (López & Levy, 2013; Moore, 2017). One common factor throughout these studies is stigma, which is known to be associated with less favorable attitudes toward seeking help (Moreland et al., 2018). However, researchers have not explored how stigma and attitudes might influence intentions to seek counseling and actual help-seeking behaviors in student-athletes. Additionally, there is a dearth of research identifying the topics for which student-athletes are most willing to seek help. Therefore, the purposes of this study were to investigate predictors of mental …

An Assessment Of Emotional-Force And Cultural Sensitivity The Usage Of English Swearwords By L1 German Speakers, Sarah Dawn Cooper

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examines the usage of English swearwords by L1 German speakers and poses the following three questions: (1) Which English swearwords do native-speakers of German use? (2) In which situations do German speakers use English swearwords? Why do they use English swearwords instead of their German counterparts? (3) What emotional weight do they apply to swearwords in English (i.e. How taboo are they)? In an effort to understand Germans’ use of swearwords today, potential attributing factors were assessed and evaluated in a 15-question survey comprised of both qualitative and quantitative components that was taken by 403 participants from Germany …

Data collected included teacher, student, and parent interviews and classroom observations. Data were analyzed using a socio-cultural narrative analysis and narrative thematic analysis. Results from analysis created thick descriptions of the teacher’s journey to teaching, her existing practices, her experiences learning and implementing the framework, and her future curricular intentions. Developments in the teacher’s practice included establishment of scope and sequence, a sharing of power, and embracing students’ identities through …

Effects Of E-Cigarette Flavoring Chemicals On Human Macrophages And Bronchial Epithelial Cells, Anna Manzi Morris

Graduate Theses, Dissertations, and Problem Reports (ETD)

E-cigarettes and vapes are relatively new devices which are popular among young adults and teens. These devices vaporize an “e-liquid” for the user to inhale, which typically contains a mixture of propylene glycol (PG), vegetable glycerin (VG), varying concentrations of nicotine, and flavoring chemicals. Due to these flavoring chemicals being intended for ingestion as a food additive, their respiratory health effects are not well understood. Thousands of e-cigarette flavors are available on the market, many of which have the potential for toxicity. The majority of e-liquid flavoring chemicals (ELFCs) have not been tested for inhalation safety. In this study, we …

Enhancing Water Stress Tolerance In Floriculture Crops, Suejin Park

Graduate Theses, Dissertations, and Problem Reports (ETD)

Water deficit is one of the major constraints on plant growth and development, causing reduction of crop productivity. To minimize water loss, among many adaptation strategies, plants close their stomata to reduce transpiration. The stomatal closure is regulated by light, internal CO2 concentration, and plant hormones, mainly abscisic acid. Plants’ response mechanisms to water deficit are complex processes involving numerous genes and various signaling pathways. Floriculture crops are often exposed to water deficit during shipping and retailing, and these periods often result in damaged crops and profit loss. Understanding of plant responses to water deficit stress will provide us an …
