Effect Of Clay And Salinity On Asphaltene Stability, Ahmet Birkan Demir
Effect Of Clay And Salinity On Asphaltene Stability, Ahmet Birkan Demir
Graduate Theses, Dissertations, and Problem Reports (ETD)
Asphaltenes are fractions of crude oil and precipitate out due to change in pressure, temperature, and composition. Because the most significant pressure and temperature change occur at near wellbore region, asphaltenes precipitation occurs at this area which prevents oil flow due to significant reduction in permeability.;This study investigates the effect of salinity and clay type on asphaltene stability. To reach this goal, the stability of asphaltenes from five different crude oil samples were evaluated after exposing them to different brine concentrations with the absence and presence of porous medium. Porous mediums were prepared by using either Ottawa Sand or Ottawa …

Experiences Of Parents Of Children Adopted From Overseas: A Thematic Analysis Of Narratives, Ekaterina Anatolyevna Amarando
Graduate Theses, Dissertations, and Problem Reports (ETD)
Parents from the United States adopt more children from overseas than parents from any other country. There are numerous factors that play a role in the decision to adopt internationally, and most families remain highly satisfied with the adoption outcome (Adoption Institute, 2010). However, families with internationally adopted children face numerous challenges during their adoption journey, and generally report a higher utilization of professional services than biological families (Adoption Institute, 2010). In this study I utilized a qualitative research design to examine experiences of parents who adopted children from other countries. Thematic analysis of family narratives was employed to examine …
How Far Is Too Far? Understanding Identity And Overconformity In Collegiate Wrestlers, Ashley M. Coker-Cranney
How Far Is Too Far? Understanding Identity And Overconformity In Collegiate Wrestlers, Ashley M. Coker-Cranney
Graduate Theses, Dissertations, and Problem Reports (ETD)
Although athletes who endanger the health and well-being of others are publicly shamed, those who endanger their own health and well-being in an effort to embody the sport ideal are often praised. Athletes are expected to distinguish themselves from their peers, make sacrifices for the good of the game, play through pain and injury, and push physical and mental limits on the path to achieve their goals (Hughes & Coakley, 1991). Collectively, these expectations are known as the "sport ethic" and while they are considered part of sport culture, athletes who overconform to them may engage in behaviors that risk …

Graduate Theses, Dissertations, and Problem Reports (ETD)
With greenhouse gas emissions becoming a major concern and topic for research over the past decade, much effort has been supplied into the progress of reducing these emissions. Carbon dioxide concentration has increased over past 60 years. A major source of this emission is post combustion coal power plants. In order to reduce these emissions, many carbon capture and storage technologies are being researched and developed. A major issue confronting this research is investigating these technologies on multiple scales. For example, solid sorbents experience phenomena on a quantum and macroscopic scale. Thus a bridge must be made between these two …
Climate Change, Capitalism, And Citizen Science: Developing A Dialectical Framework For Examining Volunteer Participation In Climate Change Research, Joshua A. Wixom
Climate Change, Capitalism, And Citizen Science: Developing A Dialectical Framework For Examining Volunteer Participation In Climate Change Research, Joshua A. Wixom
Graduate Theses, Dissertations, and Problem Reports (ETD)
This dissertation discusses the complex social relations that link citizen science, scientific literacy, and the dissemination of information to the public. Scientific information is not produced in value-neutral settings by people removed from their social context. Instead, science is a social pursuit and the scientist's social context is embedded in the knowledge produced. Additionally, the dissemination of this information via numerous media outlets is filtered through institutional lenses and subject to journalistic norms. As a result, the general public must be able to recognize the inherent biases in this information. Yet, the rates of scientific literacy in the U.S. are …

Perceptions Of The Bereaved: Attributions, Emotions, And Prosocial Behavior, Christine Weir
Perceptions Of The Bereaved: Attributions, Emotions, And Prosocial Behavior, Christine Weir
Graduate Theses, Dissertations, and Problem Reports (ETD)
This study explored a new application of Weiner's Attributional Model to suicide bereavement, and how friends and coworkers respond in their emotions and prosocial behavior. This is a comprehensive theoretical model addressing how people respond to negative events occurring in the lives of others. Its premise is the influence of attributions on the behavior, affect, and cognitive processes of the helper. The model's broad underpinnings are that attributions for challenging behavior can in turn produce a crucial effect on helping behavior. Previous qualitative research on suicide survivors has suggested that attitudes and beliefs towards suicide survivors by those in the …

Microfluidic Based Hydrate Permeability System: Design And Construction, Matthew Tacker
Microfluidic Based Hydrate Permeability System: Design And Construction, Matthew Tacker
Graduate Theses, Dissertations, and Problem Reports (ETD)
Methane hydrates represent a vast and untapped fossil fuel resource underlying large portions of the world's artic continental surfaces and sub-sea continental shelves. These hydrates are crystalline solids that consist of methane molecules surrounded by cages of interacting water molecules, similar to ice. Methane hydrates occur naturally, where temperature and pressure conditions favor their formation. In order to utilize these resources, methods must be developed to determine the conditions most favorable to hydrate extraction. One important condition is permeability and how it is affected by hydrates. Due to the difficulty and cost of field studies, the study of laboratory-synthesized hydrates …

Situational Awareness Enhancement For Connected And Automated Vehicle Systems, Amin Tahmasbi Sarvestani
Graduate Theses, Dissertations, and Problem Reports (ETD)
Recent developments in the area of Connected and Automated Vehicles (CAVs) have boosted the interest in Intelligent Transportation Systems (ITSs). While ITS is intended to resolve and mitigate serious traffic issues such as passenger and pedestrian fatalities, accidents, and traffic congestion; these goals are only achievable by vehicles that are fully aware of their situation and surroundings in real-time. Therefore, connected and automated vehicle systems heavily rely on communication technologies to create a real-time map of their surrounding environment and extend their range of situational awareness. In this dissertation, we propose novel approaches to enhance situational awareness, its applications, and …

This dissertation is a collection of essays that incorporate institutional analysis into Economics of Gender research. I specifically consider the role of institutional arrangements in the economic status of women, opportunities the institutional arrangements create for women, and outcomes of changes in institutional arrangements that affect women. In chapter 2 I investigate the relationship between income distribution inequality and labor mobility, as globalization is viewed in the existing literature as aiding income inequality by allowing greater capital mobility but not mobility of labor. The literature argues that globalization creates changes in bargaining power for labor and capital owners thus decreasing …
Sites Of Education: Race, Memory, And The Conflicting Discourses Of Learning In America, 1827-1914, Douglas Terry
Sites Of Education: Race, Memory, And The Conflicting Discourses Of Learning In America, 1827-1914, Douglas Terry
Graduate Theses, Dissertations, and Problem Reports (ETD)
This dissertation is a cultural study that challenges the handling of race in the history of American education by exploring how educational discourse shapes race. It argues that education itself is a manifestation of race, inseparable from the iterative processes of racial formation. While we take it as a prevailing truism that race is learned, this dissertation shows how the educational system itself is central to this learning.;It explores race in the educational landscape in a similar way to how scholars explore tension between history and cultural memory. In this manner, the dissertation focuses on what it terms "sites of …

Ordinary Sailors: The French Navy, Vichy And The Second World War, Alexander John Upward
Ordinary Sailors: The French Navy, Vichy And The Second World War, Alexander John Upward
Graduate Theses, Dissertations, and Problem Reports (ETD)
After the debacle of the Fall of France in 1940, the one organization that managed to maintain its discipline and functionality virtually intact was the French Navy. This is the story of how subsequently that navy was able to exert a disproportionate influence on the Vichy regime of Marshal Petain. Such influence achieved its apogee between February 1941 and April 1942 when the navy's Commander-in-Chief Admiral Darlan served simultaneously in several of the regime's highest offices. During this period France continued to flirt with the possibility of actively engaging Great Britain in war on the side of Nazi Germany. It …
The Effects Of Overprotective Parenting On Academic Self-Esteem: The Moderating Role Of Teachers, Brittany R. Valdez
The Effects Of Overprotective Parenting On Academic Self-Esteem: The Moderating Role Of Teachers, Brittany R. Valdez
Graduate Theses, Dissertations, and Problem Reports (ETD)
Overprotective parenting, or "helicopter parenting" as it is known in the media, is characterized by high levels of behavioral and psychological control, and has been found by previous empirical studies to be linked to several maladaptive child outcomes (Wood, McLeod, Sigman, Hwang, & Chu, 2003). These outcomes include increased levels of anxiety, depression (Bayer, Sanson, & Hemphill, 2006; LeMoyne & Buchanan, 2011; Schiffrin, Liss, Miles-McLean, Geary, & Erchull 2013), and shyness (Bayer, et al., 2006; Rubin, Coplan, & Bowker, 2009) as well as decreased academic outcomes (Bernstein & Triger, 2010; Padilla-Walker & Nelson, 2012). However, much of the research regarding …

Examining The Link Between Sexually Explicit Media Use And Sexual Risk Behavior Among Adolescents And Young Adults, A. Jamesa Wagwau
Graduate Theses, Dissertations, and Problem Reports (ETD)
The current study examined the link between sexually explicit media use and the different forms of sexual risk-taking among emerging adults. The study focused on emerging adults aged 18 -- 25 years. This is a critical stage for sexual risk-taking which has not been adequately investigated by prior studies. Using online data collected from 146 American based young adults (45.1% female; 74.6% European American, 9.7% Asian /Asian American, 6.7% Black/African American, 0.7% Native American and 8.2% Multiethnic, mean age = 22.89 years), sexually explicit media use was analyzed in connection with sexual risk-taking variables (i.e., multiple sexual partners, condom use …
Board Out Of Your Mind: Mapping Players' Mental Models Of Game Systems And Potentials For Systems-Thinking Instruction, Joe A. Wasserman
Board Out Of Your Mind: Mapping Players' Mental Models Of Game Systems And Potentials For Systems-Thinking Instruction, Joe A. Wasserman
Graduate Theses, Dissertations, and Problem Reports (ETD)
Despite evidence that game-based instruction is effective, and suggestive evidence that they are specifically effective for teaching systems thinking---the ability to think about complex systems---the mechanisms behind this learning are not well understood. One promising perspective on game-based learning is rooted in the development of mental models of game systems. Mental models are cognitive representations of the perceived entities and relationships between entities in a system. This study explores the entities and entity relationships in novice players' mental models of an analog game. Grounded, interpretive analysis of mental models externalized through cognitive mapping identified five categories of entities: formal game …
Utilization Risk Assessment And Thermal Conductivity Testing For The Low Temperature Geothermal Play Fairway Analysis For The Appalachian Basin, Kelydra Welcker
Utilization Risk Assessment And Thermal Conductivity Testing For The Low Temperature Geothermal Play Fairway Analysis For The Appalachian Basin, Kelydra Welcker
Graduate Theses, Dissertations, and Problem Reports (ETD)
In order to alleviate the large carbon footprint of fossil fuel technology, renewable energy has begun to gain momentum with consumers and industries alike. Geothermal energy has the benefit of providing a reliable energy source with only 5% of the carbon dioxide emissions of fossil fuels, as well as provide a means of carbon sequestration. The application for this energy source is highly dependent on several factors, including reservoir characteristics, temperature, and regional demand. High temperature systems (>150 °C) are best suited for electricity production, while low and medium temperature reservoirs (<90 °C and 90-150 °C, respectively) may be better suited for direct use applications, such as manufacturing purposes or district heating and cooling for commercial and residential areas.;Enhanced, or engineered, geothermal systems (EGS) may provide a means to take advantage of geothermal reservoirs with lower available temperatures. To determine the efficacy of EGS technology in eastern United States, a play fairway analysis was performed on the Appalachian basin. Risk factors examined include thermal resource quality, natural reservoir quality, induced seismicity, and utilization opportunities, which is a focus of this work. Levelized cost of heat, or LCOH, was used to provide a comparison of factors, such as combination of capital costs, operation and maintenance costs, and performance and fuel costs. To determine LCOH, commercial, residential, and infrastructure data were collected from the US Census and fed into GEOPHIRES, a program that uses surface piping, heat exchange equipment (residential and/or commercial), operations, upfront capital cost, and maintenance costs over the lifetime of a 30-year project. The impact of industrial demand on LCOH, such as process heating and cooling and HVAC, for dairy, wood drying, and paper mills were also examined.;Heat flow estimates are equally important in the selection of potential geothermal sites. Estimation of the temperature-at-depth uses heat flow, which is dependent on factors including geothermal gradient and thermal conductivities. Thermal conductivity is a function of depth and position, and for some models is calculated as a weighted average based on thicknesses of lithographic layers. Obtaining actual thermal conductivities can be challenging, and often require the use of databases to predict the geographic variation. For this project, thermal conductivities from Marion County well #244 rock cuttings were found using a portable electronic divided bar (PEDB) system and were compared to COSUNA estimates to assess the current model method.
Migratory Genomics Of Lake Sturgeon, Justine Whitaker
Migratory Genomics Of Lake Sturgeon, Justine Whitaker
Graduate Theses, Dissertations, and Problem Reports (ETD)
Lake sturgeon are large, freshwater fish and the only species of sturgeon native to the Great Lakes. Their historic range extends from the Hudson Bay, down through the Great Lakes and into the Mississippi River basin. In the early 1900's, sturgeon became a valuable fishery and were soon overfished for both meat and caviar. This, in combination with damming, pollution, and habitat degradation, caused a drastic decline in their population. Some populations were extirpated, while others have been reduced to 1% of their historic population size (Auer, 1996). The St. Clair-Detroit River System (SCDRS) hosts one of the largest lake …
Nursing Knowledge Of Heart Failure, Beth Ann White
Nursing Knowledge Of Heart Failure, Beth Ann White
Graduate Theses, Dissertations, and Problem Reports (ETD)
Heart failure is a constellation of signs and symptoms reflecting a physiologic change in the hearts ability to keep up with demand. Heart failure is considered a global pandemic and is a complex disease that oftentimes is progressive. Heart failure is often associated with underlying coronary atherosclerosis, and its associated risks, including hypertension, diabetes mellitus, metabolic syndrome and dyslipidemia. To slow the progression and improve quality of life patients should be educated about the disease and in most health care settings nurses provide this education. However, nurses may lack sufficient knowledge of the processes that lead to heart failure. The …
