Noncovalent Interactions Involving Microsolvated Networks Of Trimethylamine N-Oxide, Kristina Andrea Cuellar Jan 2014

Noncovalent Interactions Involving Microsolvated Networks Of Trimethylamine N-Oxide, Kristina Andrea Cuellar

Electronic Theses and Dissertations

This thesis research focuses on the effects of the formation of hydrogen-bonded networks with the important osmolyte trimethylamine N-oxide (TMAO). Vibrational spectroscopy, in this case Raman spectroscopy, is used to interpret the effects of noncovalent interactions by solvation with select hydrogen bond donors such as water, methanol, ethanol and ethylene glycol in the form of slight changes in vibrational frequencies. Spectral shifts in the experimental Raman spectra of interacting molecules are compared to the results of electronic structure calculations on explicit hydrogen bonded molecular clusters. The similarities in the Raman spectra of microsolvated TMAO using a variety of hydrogen bond …

A Behavioral Intervention For Child Obesity: Increasing Physical Activity On The Playground Via Reinforcement In A Preschool Classroom, Kevin Francis Karl Jan 2014

A Behavioral Intervention For Child Obesity: Increasing Physical Activity On The Playground Via Reinforcement In A Preschool Classroom, Kevin Francis Karl

Electronic Theses and Dissertations

Child obesity rates have reached an all-time high in the United States with rates quadrupling since 1963 for children ages 2-5 (Fryar, Caroll, & Ogden, 2012). This has led to increased research directed toward understanding the causes of this proliferation. The literature shows that several key variables, including physical activity level, diet, and health education are related to childhood obesity (Epstein, 2005; Trost, et al., 2003). In the realm of physical activity level, many interventions have been proposed and conducted with varying degrees of success. Only few have attempted to impact the physical activity level of children in free play, …

Financial Reporting Manipulation And The Role Of Religious Ownership: Evidence From Nonprofit Hospitals, Ryan Seay Jan 2014

Financial Reporting Manipulation And The Role Of Religious Ownership: Evidence From Nonprofit Hospitals, Ryan Seay

Electronic Theses and Dissertations

Empirical evidence (e.g. Eldenburg and Vines 2004; Leone and Van Horn 2005; Ballantine et al. 2007; Eldenburg et al. 2011) demonstrates that nonprofit hospital managers respond to competing institutional and regulatory pressures by engaging in various forms of financial reporting manipulation. While some recent research in accounting (e.g. Dyreng et al. 2012; McGuire et al. 2012) shows that religious social norms can deter this undesirable behavior, these studies focus on the private, for-profit sector and use a location-based measure of religiosity. This study extends this line of research by using a more direct measure of religious social norms, the ownership …

Growth Of Bald Cypress Boles And Knees As Influenced By Precipitation And Inundation At Sardis Lake, Mississippi, Emily M. Stauss Jan 2014

Growth Of Bald Cypress Boles And Knees As Influenced By Precipitation And Inundation At Sardis Lake, Mississippi, Emily M. Stauss

Electronic Theses and Dissertations

The growth of bald cypress (Taxodium distichum) boles and knees in response to inundation and precipitation over small (< 4 m) elevation gradients was examined by measuring interannual growth increments of boles and knees at five sites at Sardis Lake, Mississippi. There was a significant (p=0.019) growth response to precipitation during November to April (the wet season), but there was not a significant growth response to inundation during the growing season (May to October). Because lake level at Sardis is controlled by the Army Corps of Engineers for flood control, the Sardis Lake shoreline area may be a habitat where growth response to precipitation and inundation differs from systems where precipitation and inundation are linked. The growth of knees from bald cypress roots was compared to growth of the boles in order to determine if knees and boles respond to the same environmental factors. It was found that the knees have high positive correlation coefficients when compared to the tree's bole if we assume that knee growth is initiated in response to a major flood event. If we assume knees grow in response to stress that limits bole growth, we would expect but do not find any discernable relationship between the initiation of knee growth and the timing of flood events.

Structural Analysis Of Bulky Thiolate-Protected Gold Nanomolecules, David Walton Crasto Jan 2014

Structural Analysis Of Bulky Thiolate-Protected Gold Nanomolecules, David Walton Crasto

Electronic Theses and Dissertations

Routine preparation of thiolate-protected gold nanomolecules involves, most commonly, straight-chain organic thiolate ligands for which the sulfhydryl `head' group is bound to a primary carbon atom. The primary connectivity of these sulfur atoms, such as for the case of n-hexanethiol and phenylethanethiol, allows for even packing, and the relative ease of formation of gold-thiolate oligomers about the surface monolayer in the formation of Au-SR bonds. Moreover, these straight-chain ligands routinely support the formation of an icosahedron-based series of core-size gold nanomolecules. Within this series of nanoparticles, Au25(SR)18 and Au38(SR)24 are among the most commonly studied core-sizes; Au25(SR)18 is situated upon …

Optimized Image Compressed Sensing And Transmission Through Wireless Channels, Saheed Olanigan Jan 2014

Optimized Image Compressed Sensing And Transmission Through Wireless Channels, Saheed Olanigan

Electronic Theses and Dissertations

This thesis examines the robust behavior of quantized compressed sensing measurements during transmission through an additive white gaussian noise wireless channel. The poor rate-distortion performance that accompanies compressed sensing after applying quantization has led to several works in quantized compressed sensing. However, most of these works have less consideration of the effect of transmission channel on the resulting bit stream of the quantized compressed sensing measurements. For an additive white gaussian noise wireless channel model, the quantizer and bit energy signal-to-noise ratio determines the degree of the channel effect. This thesis explores the effect of quantization and channel noise during …

Uneven Ground: Figurations Of The Rural Modern In The U.S. South, 1890-1945, Benjamin S. Child

Electronic Theses and Dissertations

New modernist studies has opened wide the discussion about what modernism means, when it begins, and, compellingly for the purposes of this project, where it occurs. Exploring intersections between modernization, modernism, labor, and segregation in the agricultural South, this dissertation demonstrates how the effects of nascent industrialization, emergent technologies, and "modern" thought are animated by figures and spaces associated with--or performing--versions of rurality. The project is divided into three major sections. In the first, I suggest that the contradictions of African American life in the post-Reconstruction world are parsed in the period's literature through the presence of a veiled georgic …

Three Essays On Diversification Strategy, Diversification Performance, And Corporate Misconduct, Brandon Charles Lee Morris Jan 2014

Three Essays On Diversification Strategy, Diversification Performance, And Corporate Misconduct, Brandon Charles Lee Morris

Electronic Theses and Dissertations

The first essay investigates the relationship between diversification strategy and firm performance in the U.S. property-liability insurance industry. Prior literature has evaluated the effect of total diversification on insurer performance; however, there is an absence of evidence on the effect of diversification strategy for multi-line insurers. Theory suggests that related diversifiers should benefit from economies of scope while unrelated diversifiers should benefit from uncorrelated earnings streams. We test for the net effect of diversification strategy and find that relatedness negatively impacts accounting performance. However, we find that the relatedness penalty is confined to stock insurers while mutual insurers' profitability appears …

Sectionalism, Nationalism, And The Agrarian Revolt, 1877-1892, Benjamin Houston Turner Purvis

Electronic Theses and Dissertations

The Southern Farmers' Alliance led the largest coalition of late-nineteenth-century farmers' and urban reformers. The reform movement called for laws opposing speculation on agricultural prices, restricting the powers of business trusts, regulating railroad freight rates, and increasing the circulation of currency based on silver. Advocates also strongly opposed the proponents of sectionalism who emphasized differences and conflicts between the primary sections of the country, the North and the South. Differences between the North and South largely revolved around the issue of slavery and emerged shortly after the founding of the nation. Tension accelerated in the years following the Mexican-American War …

Moderation And Mediation Of Headache-Related Disability: The Roles Of Self-Efficacy And Headache Diagnosis, Kelly Peck Jan 2014

Moderation And Mediation Of Headache-Related Disability: The Roles Of Self-Efficacy And Headache Diagnosis, Kelly Peck

Electronic Theses and Dissertations

Primary headache disorders such as migraine and tension-type headache are some of the most frequently-diagnosed health disorders in the world and can be extremely disabling. However, disability resulting from these disorders varies substantially across individuals. Although headache severity has been identified as the strongest predictor of headache-related disability, the relationship between the two variables is non-linear, suggesting that other mechanisms may be involved. Self-efficacy mediates relations between pain and impairment associated with other chronic pain conditions, but this relationship has not been evaluated in a sample of individuals with primary headache disorders. Therefore, the present study sought to examine whether …

The Role Of Acceptance In Headache-Related Variables, Joshua D. Hamer Jan 2014

The Role Of Acceptance In Headache-Related Variables, Joshua D. Hamer

Electronic Theses and Dissertations

Migraine is a neurologic disorder that causes impairment in many areas of functioning. Migraine sufferers frequently avoid environmental stimuli (triggers) they assume to be associated with migraine onset, which may inadvertently lead to an increase in the potency of some triggers and increase headache frequency over time. Headache patients who instead use acceptance strategies to limit their attempts to control or eliminate/avoid their pain may experience reduced distress and pain-related disability. Studies examining acceptance-based approaches in managing chronic pain conditions have shown favorable results of acceptance on pain intensity, reduced pain-related anxiety and avoidance, and less physical and psychological disability. …
