Three semi-structured focus group interviews were conducted with 18 Mexican women (n = 10) and men (n = 8; Mage = 23) coaches who completed the program. Using a social constructivist framework, reflexive thematic analysis was used to examine the …

Health Disparities By Sexual Orientation Components In The United States, Julia Kay Wolf

Graduate Theses, Dissertations, and Problem Reports

Fundamental cause theory encourages researchers to consider broad social conditions that put people at risk of individual-level health-related risks that can lead to health disparities between social groups. Stigma has recently been proposed as a fundamental cause of health disparities as it influences multiple disease outcomes, affects access to resources, and is consistently related to health inequities across historical and geographical contexts. Minority stress theory describes how sexual minorities endure excess stressors in the form of prejudice and discrimination due to their stigmatized status. Considering both frameworks, I explore how stigmatized sexual orientation minority respondents compare to their sexual majority …

Support vector machine (SVM) and random forest (RF) machine learning models were used with various combinations of …

More Than One Story: A Bioecological Model Of Elementary Educators’ Perceptions And Representations Of Diversity, Angela Curfman

Graduate Theses, Dissertations, and Problem Reports

Classroom teachers have long employed children’s literature in the classroom. Exposure to children’s literature offers a plethora of gains and benefits. Through the usage of children’s literature, critical thinking skills are fostered and factual information is obtained (Hancock, 2000). Varied cultures, linguistic backgrounds, families with diverse socio-economical, and academic backgrounds constitute our public school classrooms. Children’s literature provides readers an opportunity for self-affirmation; therefore, they often seek a mirror in books, (Bishop, 1990). The thoughtful selection of children’s literature in the classroom is essential. Through the lens of Bishop’s (1993) metaphorical notion of books as mirrors, windows, and sliding glass …

Dynamic Data-Driven Smart Proxy Modeling For Numerical Reservoir Simulation, Maher Jasim Alabboodi

Graduate Theses, Dissertations, and Problem Reports

A successful Geologic Carbon Dioxide (CO₂) Storage (GCS) operation requires the ability to make quick and reliable subsurface modeling decisions; such decisions must be made based on an accurate and realistic modeling of the reservoir. Numerical reservoir simulation is the most common tool used for predicting fluid flow behavior and analyzing uncertainties in the subsurface reservoirs.

In general, a numerical reservoir simulation model has tens of millions of grid blocks and requires intensive computations to be performed at each time-step of the simulation, therefore, they are computationally expensive and time-consuming. As a result, studies (such as uncertainty analysis …

Design Of Bending Moment And Load Capacity Test For Frp Sheet Piles, Joshua Larry Wilt Mr.

Graduate Theses, Dissertations, and Problem Reports

Sheet piles consist of numerous interlocked segments that form temporary or permanent support walls and serve as the primary foundational component across a variety of civil infrastructural applications, such as below-grade parking structures or sea walls. The installation of sheet piles is particularly advantageous in coastal areas, as dewatering of the site is unnecessary. Steel is commonly used for sheet piles due to its strength and ease of manufacturing; however, in the presence of saltwater steel begins to rust.

The effect of three metallic chloride catalysts (LiCl, FeCl3.6H20, CuCl2) on the conversion of xylan to furfural was also investigated. The gamma-valerolactone-ferric chloride sent system exhibited the highest mean yield of furfural (56.50%). The next highest furfural yield of …

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

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 …

Soil Response Of Helicopter Liming In The Monongahela National Forest, Jarrett Douglas Fowler

Graduate Theses, Dissertations, and Problem Reports

Soils in the Monongahela National Forest (MNF) are acidic due to sandstone parent material, acid deposition, uptake of base cations by vegetation, and release of organic acids by organic matter (OM) decomposition. Increases in soil acidity have caused declines in forest health and changed species composition and nutrient status. Liming can neutralize soil acidity, but no large-scale liming projects have been done on acid forest soils in the USA. In anticipation of acquiring funding for a proposed liming project in the MNF, in 2007 and 2009 10 sites were selected to sample and analyze soils before lime was applied. In …

Population Genetics Of A Reintroduced Fisher (Pekania Pennanti) Population In West Virginia, Caroline E. Harms

Graduate Theses, Dissertations, and Problem Reports

Fishers (Pekania pennanti) were reintroduced in West Virginia in 1969 with no population wide genetic analysis ever having been conducted. Genetic analysis of reintroduced populations is vital to assess genetic diversity as an indicative of population viability. My objective was to collect fisher samples throughout West Virginia, nearby states where fisher may be migrating (PA and NY), and the New Hampshire source population to provide a full genetic interpretation of the reintroduced West Virginia population. Genetic analysis was used to measure genetic diversity, admixture or delineation of subpopulations, and effective population size. Sample location and genetic data were …

Three Essays In Applied Urban Economics, Alexander Cardazzi

Graduate Theses, Dissertations, and Problem Reports

The first chapter examines the effect of policing strategies on housing prices. Crime has been shown to negatively affect housing values. However, there is not much empirical evidence documenting the amenity value of how people are policed. Stop & Frisk was a particularly salient policing tactic employed in New York City until a judge ruled it to be unconstitutional. This chapter uses exogenous variation in Stop & Frisk behavior resulting from landmark events in a federal class action lawsuit as well as exposure to Operation Impact, a high intensity policing strategy, to explain variation in property sales. Results indicate a …

A Selective Study On Chinese Art Songs After 1950, Gehui Zhu

Graduate Theses, Dissertations, and Problem Reports

The purpose of this paper is to provide an insightful study of Chinese art songs after 1950. A number of works have been written in English about the repertoire of Chinese art songs, but most of these studies concentrated on songs written before 1950. It is difficult for English speakers to find and study Chinese art songs after 1950. In fact, they have largely been ignored. However, these songs have significant pedagogical and aesthetic values. This study aims to provide musicians and voice teachers a handy and practical tool to study and sing Chinese art songs composed after 1950.

Speaking Music: A Historical Study Of Edwin Gordon's Music Learning Theory, David M. Alfred

Graduate Theses, Dissertations, and Problem Reports

Music Learning Theory, conceived, researched, and developed by Dr. Edwin Elias Gordan, has been on the periphery of music education for decades and is the only extant comprehensive theoretical framework that fully addresses the development of music literacy from early childhood through maturity. The concurrent research gap suggests that a Fordist approach may exist throughout music education – one that insists upon behavioral goals, direct instruction, and educational, artistic, and ideological exclusivity. This historical study elucidates Gordan’s work in order to understand the stages and processes that are like spokes of a wheel between his idea of audiation at the …

In/Visible, Raymond Thompson Jr

Graduate Theses, Dissertations, and Problem Reports

My MFA thesis and supporting exhibition focus on challenging the United States’ photographic archive that often left out African-American people. The work, through the use of appropriation and alternative photographic processes, disrupts America’s historical visual archive and notions that surround the white gaze. Through the unsettling of this visual space, new speculative narratives can be created to help imagine new futures. This work is the beginning of a process of mourning histories I have never known and reclaiming a place for myself and my family in the American landscape that is free of racial trauma.

Development And Dynamics Of Us Welfare Policy, Liza Gordon

Graduate Theses, Dissertations, and Problem Reports

In this dissertation I analyze the development of contemporary US welfare policy with special consideration given to the importance of race and gender. In the introductory chapter I outline how the development of the American welfare state has continuously neglected the needs of women and minorities as well as how classist, racist, and sexist appeals have been prevalent throughout US history in relation to welfare policies. The remaining chapters analyze how contemporary welfare policies including the 1996 welfare reforms and state drug-testing for welfare laws carry on these American legacies. In Chapter 1 I examine how the classist, sexist, and …

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

Graduate Theses, Dissertations, and Problem Reports

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 …
