What Elite Men's Collegiate Tennis Coaches Look For In Recruits And How They Assess Preferred Player Characteristics, Brandyn H. Fisher

Graduate Theses, Dissertations, and Problem Reports (ETD)

Understanding what characteristics college tennis coaches look for, and how they evaluate these skills may provide beneficial information related to the recruiting process at the collegiate level. Currently, limited research exists concerning how college tennis coaches evaluate a recruit's intangible characteristics and what specific characteristics they look for. Some authors have suggested that coaches highly value intangible characteristics, such as character and leadership ability, and that these skills are believed to be necessary for success at the collegiate level (Flett, Paule, & Schneider, 2010). However, little is known about the exact processes coaches use to evaluate intangible skills, nor which …

Advances In Mems Imu Cluster Technology For Small Satellite Applications, Drew E. Bittner Jan 2015

Advances In Mems Imu Cluster Technology For Small Satellite Applications, Drew E. Bittner

Graduate Theses, Dissertations, and Problem Reports (ETD)

In recent years, there has been increased interest in Micro-Electro Mechanical Systems (MEMS) Inertial Measurement Units (IMUs) due to their relatively small volumetric footprint and low-cost. Although this advantage far outweighs the volumetric footprint and cost of traditional high-performance IMUs, MEMS technology has yet to match the performance of such devices. In spite of this, it has been shown in theory that a cluster of MEMS IMUs may signicantly improve the performance over a single MEMS IMU. To further develop this theory, two prototype boards have been designed and constructed that include 16 MEMS accelerometers and gyroscopes af- xed to …

Use Of Protein Immobilization To Measure Cytochrome P450 Conduction And Metabolism Kinetics, Christopher D. Bostick Jan 2015

Use Of Protein Immobilization To Measure Cytochrome P450 Conduction And Metabolism Kinetics, Christopher D. Bostick

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cytochrome P450s (P450s) are a large family (>11,000) of heme thiolated proteins that are responsible for ~ 75% of the metabolism of pharmaceuticals on the market. Understanding P450 mediated metabolism is crucial for accurate in vitro predictions of drug metabolism. P450 protein-protein interactions have been shown to alter enzyme catalytic activity. Furthermore, these interactions are isoform specific, and can elicit activation, inhibition, or no effect on enzymatic activity. Studies show these effects are also dependent on the protein binding partner cytochrome P450 reductase (CPR), and the order of protein addition to purified reconstituted enzyme systems. In the current work, …

Attenuation Of Spatial Memory Impairment In A Tau Mouse Model Of Alzheimer's Disease With Riluzole, Daniel S. Weitzner Jan 2015

Attenuation Of Spatial Memory Impairment In A Tau Mouse Model Of Alzheimer's Disease With Riluzole, Daniel S. Weitzner

Graduate Theses, Dissertations, and Problem Reports (ETD)

Individuals at risk for developing Alzheimer's disease (AD) often demonstrate hyperactivity in areas of the memory network, such as the hippocampus, prior to AD diagnosis. Evidence suggests that this hyperactivity might be a contributing factor to the development of AD. Tau, a protein responsible for binding and maintaining microtubules, has been implicated as a factor in hyperactivity, potentially through its alterations in glutamate signaling. Glutamate, the primary excitatory neurotransmitter in the central nervous system, is essential for learning and memory. However, excess glutamate that accumulates in the synapse can lead to neuron loss and eventual behavioral impairments. Recently, our lab …

Constraints On The Pressure-Temperature Path For Belt-Purcell Supergroup Metapelites From Snow Peak, Northern Idaho, Sarah Elizabeth Johnson Jan 2015

Constraints On The Pressure-Temperature Path For Belt-Purcell Supergroup Metapelites From Snow Peak, Northern Idaho, Sarah Elizabeth Johnson

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Snow Peak area in northern Idaho experienced two distinct metamorphic episodes, M1 and M2. Garnets, especially those that experienced both episodes, are strongly zoned. The assemblages observed in metapelites from garnet to staurolite/kyanite zones were compared to computer generated assemblages calculated using Theriak-Domino (deCapitani and Petrakakis, 2010). The comparison and analysis of the assemblages, garnet zoning, and modal contours provides constraints on the path the rocks must have followed between metamorphic events called M1 and M2. The most useful constraints on the proposed P-T path are provided by comparing the content of Ca in garnet and the observed assemblage …

Synthesis, Characterization And Photocatalytic Activity Of Au-Zno Heterostructures, Oshadha Kanchana Ranasingha

Graduate Theses, Dissertations, and Problem Reports (ETD)

Heterostructures of semiconductor metal oxides and metals have been studied extensively due to the synergistic photocatalytic activity they display. Gold-Zinc oxide (Au-ZnO) heterostructured photocatalysts are one of the most widely studied photocatalysts due to the high photocatalytic activity of ZnO and the ability of Au to transfer photoexcited electrons away from ZnO, which leads to enhanced carrier separation and improved catalytic activity. Au heterostructuring is also known to alter the electronic structure of ZnO leading to better photochemical band alignment and a decreased work function which both contribute to enhanced catalytic activity. The use of Au to form heterostructures with …

What Shadows We Pursue: Death, Democracy, And Disunion In Antebellum America, Joseph M. Rizzo Jan 2015

What Shadows We Pursue: Death, Democracy, And Disunion In Antebellum America, Joseph M. Rizzo

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation examines the ways Americans registered concerns about antebellum democratic political culture through their mourning of national leaders. A "eulogizing class" consisting of clergymen, politicians, lawyers, and educators was especially prominent in shaping how contemporaries remembered the dead. As a class, the eulogists were conflicted about democracy and partisanship, and conveyed their concerns through the potentially demagogic form of the eulogy---the practice of glorifying the "great man." Through an examination of eulogies, sermons, and newspaper editorials after the deaths of William Henry Harrison, Andrew Jackson, John Quincy Adams, John Calhoun, Henry Clay, and Daniel Webster, this dissertation reveals the …

Against The Thalassocracy: Sacred Geography, Nationhood And Perennial Traditionalism In Alexander Dugin's Neo-Eurasianist Philosophy, Jonathan Rushbrook Jan 2015

Against The Thalassocracy: Sacred Geography, Nationhood And Perennial Traditionalism In Alexander Dugin's Neo-Eurasianist Philosophy, Jonathan Rushbrook

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis discusses the ideological makeup of the Russian right wing philosopher Alexander Dugin's and his conceptualization of race and nation in his Neo-Eurasianist imperial project. Tracing Dugin's ideological influences from early Eurasianism, the European New Right and esoteric religious beliefs such as Perennial Traditionalism, the thesis then goes on to place Dugin's body of thought within a larger debate on defining fascism and whether Dugin can be considered a fascist. Ultimately this thesis contests some scholars' interpretations of Dugin's worldview as a fundamentally ethnocentric or even racist Russian nationalism. Rather, by examining Dugin's writings on nation through an ethno-symbolist …

Use Of Wireless, Ad-Hoc Networks For Proximity Warning And Collision Avoidance In Surface Mines, Venkata Raghava Siva Naga Shashank Sabniveesu

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite the record of progress achieved in the United States with respect to reducing fatal and non-fatal injuries in surface mines, both the number and severity of these injuries remain unacceptable. A large fraction of these injuries in surface mines are caused by collisions involving large haulage equipment such as trucks, dozers, and front-end loaders. There are two main contributing factors for these collisions: (i) the massive size of these vehicles, which causes several blind spots surrounding the vehicle for the driver, and (ii) the sheer momentum of these vehicles, which makes it hard to maneuver these vehicles and often …

Pose Performance Of Lidar-Based Relative Navigation For Non-Cooperative Objects, Jordan L. Sell Jan 2015

Pose Performance Of Lidar-Based Relative Navigation For Non-Cooperative Objects, Jordan L. Sell

Graduate Theses, Dissertations, and Problem Reports (ETD)

Flash LIDAR is an important new sensing technology for relative navigation; these sensors have shown promising results during rendezvous and docking applications involving a cooperative vehicle. An area of recent interest is the application of this technology for pose estimation with non-cooperative client vehicles, in support of on-orbit satellite servicing activities and asteroid redirect missions. The capability for autonomous rendezvous with non-cooperative satellites will enable refueling and servicing of satellites (particularly those designed without servicing in mind), allowing these vehicles to continue operating rather than being retired. Rendezvous with an asteroid will give further insight to the origin of individual …

The Role Of Self-Efficacy And Social Support In Emerging Adults' Physical Activity, Nicole M. Silva Jan 2015

The Role Of Self-Efficacy And Social Support In Emerging Adults' Physical Activity, Nicole M. Silva

Graduate Theses, Dissertations, and Problem Reports (ETD)

Emerging adulthood is a time where emerging adults develop health behaviors that persist throughout the life span (Barnett et al., 2014). However, only 55.4% of emerging adults engage in the recommended amount of physical activity each week (U.S. Department for Health and Human Services, 2013). The current study examined two factors that are associated with physical activity, specifically self-efficacy and social support, in 403 (M age = 19.25, SD = 1.12) emerging adults. Linear regressions indicated that emerging adults who reported higher levels of general self-efficacy (beta = .13, p < .05), domain self-efficacy (beta = .33, p < .05), and support from the entire social network (beta = .50, p < .001) engaged in more physical activity. Support from the entire social network still accounted for a significant portion of the variance in physical activity when accounting for general or domain self-efficacy (beta for support = .48, p < .001 and .30, p < .05, respectively). The differential effects of source of support (i.e., family and friends) and type of support (i.e., esteem support, informational support, and companionship support) were also examined. Emerging adults who reported higher levels of support from family (beta = .22, p < .001) and friends (beta = .33, p < .001) engaged in more physical activity. Although emerging adults reported receiving more esteem support from family (M = 2.95, SD = 1.23) compared to friends (M = 2.74, SD = 1.15), esteem support from friends (beta = .33, p < .001) had a larger effect on physical activity than esteem support from family (beta = .21, p < .05).

Christ In The Margins: Confronting Racism Through The (Written) Word In Post-Civil War America, Cara L. Snider

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation examines fictional texts of the late nineteenth century in order to recover the response of progressive Christian writers facing a growing tide of racial violence, injustice, and segregation in the postbellum decades. By investigating the works of Mark Twain, Charles Sheldon, Frances Harper, and Sutton Griggs, I argue that we gain access to a cadre of writers who sought to translate emerging strains of New Theology into practical means of race reform. They regarded their novels as sermons to the masses and saw writing as a sacred practice of communicating the Word to fellow believers; and their brand …
