Self-Efficacy, Trait Mindfulness, And Self-Compassion As Predictors Of Risk Of Substance Use Relapse, Jonathan Nauser

Graduate Theses, Dissertations, and Problem Reports (ETD)

Previous research has demonstrated relationships among mindfulness, self-efficacy, and substance use relapse. Contrasting research has found mindfulness and self-efficacy are not consistently negatively associated with substance use relapse demonstrating a need for further research. An additional factor that has been found to associated with substance use is self-compassion; however, it has yet to be examined in relation to the process of relapse. The current study assessed self-efficacy, self-compassion, and mindfulness and their associations with substance use relapse, with the aim of predicting relapse risk. Higher levels of relapse risk were found to be negatively associated with self-efficacy, trait mindfulness, and …

Climatic Drivers Of Growth In Mixed Conifer Forests Of The Sierra Nevada For Different Tree Sizes And Thinning Treatments, Andrew M. Hirsch

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Mediterranean region of northern California is projected to get increasingly warmer under all Intergovernmental Panel on Climate Change (IPCC) emission scenarios, with future precipitation projections not showing much of a trend. This poses a problem to the already dry summers that are experienced in the Mediterranean region of California. If precipitation does not increase alongside temperatures, the dry seasons will likely only get drier. The use of dendroclimatology to assess how mixed conifer species in the Sierra Nevada responded to past climate is a key resource that can be used to infer how trees may respond to a future …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Obesity rates among middle-aged and older men in WV are among the highest in the nation. Understanding baseline and intervention factors contributing to losing clinically significant weight are essential to developing effective interventions in target groups. Thus, the purpose of this study is to determine factors associated with losing ≥ 5% of baseline weight among participants of a 12-week pilot randomized controlled telenutrition trial for middle-aged and older men in WV. The study analyzed data from 56 participants who completed the trial. Participants were classified as losing ≥ 5 % or < 5 % of baseline body weight. Diet quality was assessed using 4-day diet records and the Healthy Eating Index (HEI)-2015. Baseline factors and behavioral strategies (i.e., self-monitoring, self-efficacy, and social support) were assessed via survey. Inverse prediction analysis demonstrated that participants who lost ≥ 3.5% of baseline weight at 6 weeks were at least 75% likely to lose ≥ 5% weight at 12 weeks. Predictive models were developed using stepwise logistic regression to assess multiple predictors of losing ≥ 5% of baseline weight at 12 weeks and ≥ 3.5% of baseline at 6 weeks. Weight loss at 6 weeks was a strong predictor of weight loss at 12 weeks, in addition to previous weight loss attempts and weekly self-weight-monitoring (p

Staying Power: Examining Resistance In West Virginia, Beth Nardella

Graduate Theses, Dissertations, and Problem Reports (ETD)

West Virginia has been plagued with high unemployment rates, high rates of addiction and poverty, and some of the worst health outcomes in the country. Outmigration has been the paradigm for many, but why do some people choose to stay? Numerous scholars have written about outmigration, but there is little information on why people stay. After decades of people leaving, many who remain have made a choice to stay. This choice can be seen as an act of resistance against the problematic discourses surrounding the Appalachian region and the economic disparities found within rural communities. West Virginians are often dependent …

A Role For Endothelial Tissue-Nonspecific Alkaline Phosphatase In Blood-Tissue Barrier Health And Disease, Allison L. Brichacek

Graduate Theses, Dissertations, and Problem Reports (ETD)

Sepsis is a disorder that targets the microcirculation with significant effects at blood-tissue barriers such as the blood-brain barrier (BBB) and gut-vascular barrier (GVB). Intestinal barrier dysfunction is thought to be one of the most important contributors to multi-organ dysfunction in sepsis. As a common site of infection, the impaired gut allows the dissemination of bacteria, which exacerbates the disease pathophysiology, and can lead to long-term morbidity and mortality. The mechanisms that influence altered barrier permeability in the GVB in sepsis and other inflammatory disorders are not well understood. Tissue-nonspecific alkaline phosphatase (TNAP) enzyme activity, which has been shown to …

Predictors Of Courage In Adolescents, Yea Won Park

Graduate Theses, Dissertations, and Problem Reports (ETD)

Adolescence can be a difficult phase of life. Adolescents may experience drastic physical, psychological, social changes, which can lead to uncertainty and anxiety. Courage is an important construct to study because it could help adolescents carry out tasks, work more effectively, and pursue goals (Koerner, 2014). Few studies have investigated predictors of general courage (e.g., personality; Muris et al., 2009), and moral courage (i.e., parenting, gender; Bronstein et al., 2009). The present study examined intrapersonal and interpersonal predictors (Time 1) of courage (Time 3) among adolescents, as well as potential mediating and moderating mechanisms.

ABSTRACT

AEROSOL SAMPLING STRATEGY: Effect of Particle Transfer to Sampler Covers and Estimation of Conversion Factors between the United States and German Methods for Quartz sampling

GODWIN A. EREKAIFE

In many countries, communities of experts, including industrial hygienists, have developed unique sampling strategies to determine workers’ exposure to aerosolized particles (e.g., metals, wood dust etc.). However, using different sampling and analytical methods for the same chemical often results in different exposure levels for a similar exposure group (SEG). The exposure discrepancies among different countries that are caused by using different measurement strategies are not always systematically defined. Therefore, this study …

Searching Harder, Localizing Better, Classifying Faster: Optimizing Fast Radio Burst Detection And Analysis, Kshitij Aggarwal

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fast Radio Bursts (or FRBs) are millisecond-duration transients of extragalactic origin. They exhibit dispersion caused by propagation through an ionized medium, and quantified by Dispersion Measure (DM). Around 800 FRBs (24 repeaters) have been discovered; so far, 24 FRBs have been confidently associated with a host galaxy. In this thesis, we discuss multiple new FRB search and analysis techniques and the corresponding tools that enable us to search for FRBs harder, localize them better, and classify candidates faster.

We discuss five open-source software suites that can be used in FRB analysis. These suites are used to distinguish between FRBs and …

Response Of Forest Birds To Spotted Wing Drosophila (Drosophila Suzukii Matsumura), A Novel Invasive Fruit Pest, At Allegheny National Forest, Daniel P. Roche

Graduate Theses, Dissertations, and Problem Reports (ETD)

Non-native invasive insect pests can have dramatic impacts on native ecosystems, feeding on plant foliage, wood, or sap. Little is known, however, about how fruit-targeting NNIIPs may affect native ecosystems. Spotted wing Drosophila (Drosophila suzukii Matsumura, SWD) is a recently introduced invasive vinegar fly that parasitizes the fruits of many plant species in the United States. While its activity in agricultural systems is well-documented, little is known about its activity in forest ecosystems, despite growing evidence of its presence and parasitism of fruits there. Parasitism could reduce fruit attractiveness for vertebrate fruit consumers, including migratory birds. As such, this …

Francis Poulenc: The Compositional Influences Of Les Six And Sergei Prokofiev On The Poulenc Oboe Sonata (1962), Evan Klein

Graduate Theses, Dissertations, and Problem Reports (ETD)

This research document contextualizes the compositional influences found within Francis Poulenc’s oboe sonata. In his lifetime, Poulenc was an extremely well-connected individual, often dedicating his works to his close friends and patrons. The Sonata for Oboe and Piano, in particular, is one of these compositions dedicated to his friend and famous composer Sergei Prokofiev. Written in 1962 toward the end of Poulenc’s life, he glanced back to the start of the twentieth century for inspiration and source material. The oboe sonata is then a collage of sorts—it takes on the shared contextual principles of Les Six in which he was …
