Evaluation Of The Expectancy Challenge Alcohol Literacy Curriculum (Ecalc) For High School Students, Alyssa Dietz Jan 2016

Evaluation Of The Expectancy Challenge Alcohol Literacy Curriculum (Ecalc) For High School Students, Alyssa Dietz

Electronic Theses and Dissertations

Prevention efforts targeted at children and adolescents are important because alcohol consumption contributes to the three leading causes of death in this among 12-20 year-olds: unintentional injury, homicide, and suicide. Research on the causes of alcohol misuse traditionally focused on pharmacological and genetic explanations, but models have expanded to include cognitive processes in the development of alcohol use patterns. Alcohol expectancies, or beliefs about the effects of alcohol, are an important influence on drinking behavior. Expectancies exist prior to the initial drinking experience, predict the onset of alcohol consumption, differentiate both children and adults in terms of light- and heavy-drinking …

Superwholock: An Analysis Of Subculture In A Microblogging Setting, Dean Short Jan 2016

Superwholock: An Analysis Of Subculture In A Microblogging Setting, Dean Short

Electronic Theses and Dissertations

While subcultural research has always been a common focus of sociological research, most such studies focus on deviant subcultures. This has led to a glut of information on countercultures and criminal subcultures, but relatively little study of less visible subcultures. While there is a great deal of research on the sociology of sport, including sport fandom, there is very little on other fandom subcultures. While this makes sense, as they are niche subcultures, the popularity of formerly niche entertainment is expanding rapidly. Much of this fandom renaissance owes its existence to the Internet, and its ability to bring geographically separate …

Role Of Sleep In Exposure Therapy For Posttraumatic Stress Disorder In Oif/Oef Combat Veterans, Franklin Mesa Jan 2016

Role Of Sleep In Exposure Therapy For Posttraumatic Stress Disorder In Oif/Oef Combat Veterans, Franklin Mesa

Electronic Theses and Dissertations

Exposure therapy is theorized to reduce posttraumatic stress disorder (PTSD) symptomatology by promoting habituation/extinction of fear responses to trauma-related cues. Empirical evidence indicates that emotional memory, including habituation/extinction learning, is enhanced by sleep. However, service members with combat-related PTSD often report disturbed sleep. In this study, quality of sleep and indicators of extinction learning were examined in veterans of recent wars who had completed an exposure-based PTSD intervention. Fifty-five participants were categorized into two groups based on self-reported quality of sleep: low sleep disruption severity (LSDS; N = 29) and high sleep disruption severity (HSDS; N = 26). Participants in …

Bmp-7 Inhibits P38 And Jnk Pathways And Increases M2 Macrophage Differentiation To Reduce Atherosclerosis In Apolipoprotein E-/- Mice, Heidi Shoulders

Electronic Theses and Dissertations

We have previously shown that treating atherosclerosis with bone morphogenetic protein-7 (BMP-7) affects the presence of macrophage subtypes in vitro, however it remains unknown whether BMP-7 treatment affects development and progression of atherosclerosis in vivo at an early and mid-stage of the disease. We therefore performed a Day 5 (D5) and Day 28 (D28) study to examine BMP-7's potential to affect monocyte differentiation. Atherosclerotic plaque formation was developed using our standard method and ApoE-/- mice were sacrificed at D5 and D28 post-surgery. Treatment animals received intravenous injections of BMP-7 at 200µg/kg of bodyweight. Hematoxylin and Eosin morphological stain shows that …

Improved Interpolation In Sph In Cases Of Less Smooth Flow, Oddny Brun Jan 2016

Improved Interpolation In Sph In Cases Of Less Smooth Flow, Oddny Brun

Electronic Theses and Dissertations

We introduced a method presented in Information Field Theory (IFT) [Abramovich et al., 2007] to improve interpolation in Smoothed Particle Hydrodynamics (SPH) in cases of less smooth flow. The method makes use of wavelet theory combined with B-splines for interpolation. The idea is to identify any jumps a function may have and then reconstruct the smoother segments between the jumps. The results of our work demonstrated superior capability when compared to a particular challenging SPH application, to better conserve jumps and more accurately interpolate the smoother segments of the function. The results of our work also demonstrated increased computational efficiency …

Optical Parity Time Metasurface Structures, Ahmed El Halawany Jan 2016

Optical Parity Time Metasurface Structures, Ahmed El Halawany

Electronic Theses and Dissertations

In the last few years, optics has witnessed the emergence of two fields namely metasurfaces and parity-time (PT) symmetry. Optical metasurfaces are engineered structures that provide unique responses to electromagnetic waves, absent in natural materials. Optical metasurfaces are known for their reduced dimensionality i.e. subwavelength and consequently lower losses are anticipated. The other paradigm is the PT symmetric materials, also known as photonic synthetic matter. PT symmetry has emerged from quantum mechanics when a new class of non-Hermitian Hamiltonian quantum systems was highlighted to have real eigenvalues, hence eradicating Hermiticity of the Hamiltonian as an essential condition to the existence …

Coupling Of Laser Beams For Filament Propagation, Daniel Kepler Jan 2016

Coupling Of Laser Beams For Filament Propagation, Daniel Kepler

Electronic Theses and Dissertations

Laser filamentation is a nonlinear process involving high-energy, ultrashort pulses that create narrow, non-diffracting structures over many times the Raleigh length. While many of the characteristics of filaments can vary greatly depending on the physical parameters used to create them, they share several defining features: a high intensity core, a lower intensity cladding of photons that serves as an energy reservoir to the core, and spectral broadening into a supercontinuum. While there have been many studies on the creation and control of multiple filaments from one laser pulse and a few studies on the interaction of two single filaments, many …

An Investigation Of The Biomechanical Implications Of Lower Limb Fractures And Leg Length Disparity, Elizabeth Mills Jan 2016

An Investigation Of The Biomechanical Implications Of Lower Limb Fractures And Leg Length Disparity, Elizabeth Mills

Electronic Theses and Dissertations

One of the primary goals of biological anthropology is to develop an accurate understanding of human anatomy, health, disease, and injury in both modern and archaeological populations. Paleopathological analyses are a fruitful means of identifying disease and injury in skeletal assemblages, but the individual long-term biomechanical effects associated with pathological conditions have not yet been adequately explored in the literature. Leg fractures are a common pathological condition in both modern and archaeological populations, the effects of which may alter the biomechanics of gait. A growing body of clinical literature demonstrates that abnormal ambulatory function may have far-reaching effects in the …

Weighted Low-Rank Approximation Of Matrices:Some Analytical And Numerical Aspects, Aritra Dutta Jan 2016

Weighted Low-Rank Approximation Of Matrices:Some Analytical And Numerical Aspects, Aritra Dutta

Electronic Theses and Dissertations

This dissertation addresses some analytical and numerical aspects of a problem of weighted low-rank approximation of matrices. We propose and solve two different versions of weighted low-rank approximation problems. We demonstrate, in addition, how these formulations can be efficiently used to solve some classic problems in computer vision. We also present the superior performance of our algorithms over the existing state-of-the-art unweighted and weighted low-rank approximation algorithms. Classical principal component analysis (PCA) is constrained to have equal weighting on the elements of the matrix, which might lead to a degraded design in some problems. To address this fundamental flaw in …
