The Relationship Between Emotional Support And Health Related Self-Efficacy In Older Inmates, Deborah N. Steciak-Noujaim

Master's Theses

Inmates age 50 and older are the fastest growing segment of the prison population. Because the majority of inmates return to the community, adequate self-care is essential for managing their overall health. Studies among older community-living persons indicate that emotional support is associated with improved efficacy for managing one’s health (e.g., health related self-efficacy). Data collected from the “Physical Functioning and Mental Health of Older Prisoners” study were analyzed to determine if emotional support is associated with health-related self-efficacy among older inmates in Connecticut. Even after controlling for demographic, incarceration and clinical/behavioral factors, older inmates reporting lower levels of emotional …

Subphonemic Sensitivity In Low Literacy Adults, Monica Y.C. Li

Master's Theses

The link between phonological abilities and reading skills has been well-established in both typical and atypical language development. However, the nature of the phonological deficits in poor readers remains a debated topic. While poor readers have been mostly assumed to have underspecified or “fuzzy” phonological representations (Tallal et al., 1998), the opposite alternative, over-specified phonological representations, has also been hypothesized (Serniclaes, 2006). To examine the two phonological hypotheses, the current study used the eye-tracking paradigm in the study of Dahan et al. (2001) to investigate individuals’ sensitivity to subphonemic information in young adults with a wide range of reading abilities. …

Circadian And Circatidal Rhythms Of Protein Abundance In The Intertidal Mussel Mytilus Californianus, Cory Elowe

Master's Theses

The intertidal zone is a dynamic environment that fluctuates with the 12.4-h tidal and 24-h light/dark cycle to predictably alter food availability, temperature, air exposure, wave action, oxygen partial pressure, and osmotic conditions. Intertidal sessile bivalves exhibit behavioral or physiological changes to minimize the persistent challenges of fluctuating environmental conditions, such as adjusting gaping behavior and heart rate. At the cellular level, transcriptomic studies on mussels’ baseline circadian and circatidal rhythms have determined that the circadian rhythm is the dominant transcriptional rhythm. However, as proteins reflect the basic molecular phenotype of an organism and their abundance may differ greatly from …

Compounding Fire Disturbance History Encourages Coast Redwood (Sequoia Sempervirens) Regeneration And Community Dominance, Matthew R. Brousil

Master's Theses

Disturbance is fundamental to forest ecosystem function and overall health, but climate change is likely to increase both disturbance frequency and intensity in the future. Forests subject to increasingly frequent and intense disturbances are more likely to experience compounding disturbance effects. Compounding disturbances may exert unpredicted, non-additive stresses on ecosystems, leading to novel conditions that may exceed the capacity for local species to survive and regenerate. I further hypothesize that compounding disturbances could create conditions misaligned with species’ adaptations by altering physical and chemical growing conditions in forest soils, affecting forest composition, structure, and, subsequently, function for many years following …

Hiv Testing Avoidance: A Comparison Of Psychosocial Factors Affecting Hiv Testing In Gay And Bisexual Men, Devon Michelle Price

Master's Theses

This paper explores the role three psychosocial factors influence an at-risk individual’s decision to get tested for HIV. Two of the psychosocial factors, HIV stigma and fatalistic beliefs regarding an HIV positive diagnosis, have been well documented in the literature on HIV testing and psychosocial barriers. However, the third psychosocial factor, the tendency to avoid threatening information, has not been studied in relation to HIV testing. The present paper seeks to explore how each of these factors impact both past and present HIV testing behaviors in gay and bisexual identified men. HIV stigma and fatalistic beliefs related to an …

Fecal Bacterial Communities As An Indicator Of Trophic Interactions Among Anuran Larvae, Steven Jacob Everman

Master's Theses

Anurans are mass spawners, often with multiple females spawning together, resulting in thousands of tadpoles sharing a habitat. Such large numbers of tadpoles with limited dispersal can lead to intense competition for resources. Inter and intra-specific competition for food could have negative impacts on the growth and survival of smaller tadpoles. Fecal bacterial communities have the potential to be used as indicators of changes in diet making it possible to determine if tadpoles in the wild are eating the same food or not. After feeding on two prepared diets that differed in the percentage of complex carbohydrates, the fecal bacterial …

Master's Theses

An increasing number of preschool children exhibit challenging behavior in the classroom. Head Start children are particularly at risk for emotional and behavioral disorders due to numerous risk factors. Unfortunately, some preschool teachers are ill equipped to manage the challenging behaviors that preschool children exhibit. The current study investigated the effects of the group contingency, “Mystery Student,” on improving preschool classroom behaviors. The Mystery Student intervention is a novel, independent group contingency, with an added randomized component. An ABAB reversal design was employed to determine how effective the Mystery Student intervention was at decreasing the disruptive behaviors and increasing the …

The Elasmobranch-Microbe Relationship: Trimethylamine N-Oxide Synthesis, Urea Hydrolysis, And Microbe-Osmolyte Interactions In The Atlantic Stingray, Dasyatis Sabina, Kaitlin Kelly Doucette

Master's Theses

The elasmobranch osmoregulatory strategy is predicated on the accumulation of nitrogenous compounds, primarily urea and trimethylamine n¬-oxide (TMAO). Despite the abundance of these plasma osmolytes, it is notable that elasmobranchs appear to lack urease and TMA oxidase (Tmase), enzymes that scavenge urea-nitrogen and synthesize TMAO, respectively. However, urease and Tmase are found in many species of bacteria. Therefore, I hypothesized that intestinal bacteria are responsible for urease and Tmase activity in elasmobranchs. Absent dietary nitrogen sources, I evaluated the effects of reduced intestinal microbiota on osmoregulation in Atlantic stingray (Dasyatis sabina) in vivo. D. sabina were given …

The Effects Of Tootling Combined With Public Posting In High School Classrooms, Sarah Joan Wright

Master's Theses

The study employed an A/B/B+C multiple baseline design across classrooms. The primary focus of the study was to assess potential increases in academically engaged behavior across intervention conditions. Students in the traditional tootling phase (B) were instructed to report on their peers’ positive, prosocial behaviors. At the end of the class period, the teacher silently read through the tootles and added the total toward the group goal. When …

Modern Fair-Weather And Storm Sediment Transport Around Ship Island, Mississippi: Implications For Coastal Habitats And Restoration Efforts, Eve Rettew Eisemann

Master's Theses

The Mississippi – Alabama barrier island chain is experiencing accelerated sea level rise, decreased sediment supply, and frequent hurricane impacts. These three factors drive unprecedented rates of morphology change and ecosystem reduction. All islands in the chain have experienced land loss on the order of hectares per year since records began in the 1840s. In 1969, Hurricane Camille impacted as a Category 5, breaching Ship Island, and significantly reduced viable seagrass habitat. Hurricane Katrina impacted as a Category 3 in 2005, further widening Camille Cut. To better understand the sustainability of these important islands and the ecosystems they support, sediment …

Three-Dimensional Analysis Of The Development Of Upper Arm Musculoskeletal Stress Markers In Late Adolescents And Young Adults Of Archaic And Mississippian Populations Of Tennessee, Heather Marie Guzik

Master's Theses

This study compares three methods for the evaluation of morphology of musculoskeletal attachment sites. Two methods were macroscopic and the third was microscopic, utilizing three-dimensional laser scanning and fractal analysis The morphology of 19 upper limb attachment sites was observed in 33 males aged 15 and 30+ years, dating to the Archaic and Mississippian periods from the southeastern U.S. It was hypothesized that 1) the microscopic method would identify subtler differences than the macroscopic methods; 2) enthesis development would be greater in the Mississippian population due to the increased subsistence workload, even among younger individuals; and 3) late adolescents would …

Master's Theses

The purpose of this study is to improve spacecraft shielding from radiation in space. It focuses on the evaluation of shielding efficiency of different materials. The efficiency of a shield is evaluated by the dose profile within the shield and the amount of dose absorbed by a target using the Monte Carlo transport code called FLUKA. The output of this code is validated by recreating the experiments from published papers and comparing the results. Once the FLUKA’s output is validated, the efficiency of sixteen materials, subject to SPE and GCR sources, are evaluated. The efficiency comparison is made by fixing …

Metabolic Regulation And Cryotolerance Of In Vitro-Produced Holstein Embryos, Melissa Ann Roberts

Master's Theses

In vitro production and transfer of embryos has become a common practice within the dairy industry to efficiently breed superior animals and meet the consumption demand of the growing population. Cyropreservation is necessary for the application of commercialized embryo transfer, however, in vitro-produced embryos show morphological and physiological defects which negatively impact their ability to withstand cryopreservation in comparison to their in vivo counterparts. These artifacts result from culture conditions that cause stress to the embryo during development, leading to an accumulation of intracellular lipids, mitochondrial dysfunction, and ultimately poor ability to withstand freezing and thawing. The objective of …

The Importance Of The Multicomponent Display In Sexual Selection Of Black Morph Girardinus Metallicus (Pisces: Poeciliidae), Erin M. Wojan

Master's Theses

Multicomponent displays are composed of traits, such as coloration, structural ornaments, and behavior, that become integrated and signal information to conspecifics. Estimation of multicomponent displays in fishes often involves measurement of color traits. Fish color measurements are often obtained following immobilization via chemical anesthesia; however, the anesthetics may alter the resulting measurements, for example by darkening the skin. Girardinus metallicus, a poeciliid fish endemic to Cuba, has a multicomponent courtship and aggressive display. Black morph males exhibit black ventral coloration including the gonopodium (copulatory organ) and yellow in the non-black areas of their bodies. I investigated the effects of …

The Captivity Of Opportunity: The Conversation Surrounding Church-Going Hispanic Immigrants, Nicolet Hopper Bell

Master's Theses

Immigration is a long-standing topic of discussion in the United States. Hispanic immigrants, or families of Hispanic immigrants, living in America face unique challenges. Through focus group interviews, participants from a predominantly Hispanic Protestant church narrated their experience of living in the United States. Guided grounded theory data analysis revealed three categories and 14 subcategories, or themes of conversation, surrounding this hot topic. Participants shed light on the distinctive challenges they faced, how these challenges affected them, and how they attempted to overcome these difficulties. By exploring these results through the lens of social stigma theory (Goffman, 2009) and intergroup …

Beyond Economics: The Effects Of Religion, Migration, And Women’S Education On Nonmarital Fertility In Poor Counties, Jessica E. Yorks

Master's Theses

Existing research shows that poor economic conditions such as job loss, low wages, and financial insecurity increase nonmarital fertility. However, there are economically-depressed areas of the United States that have low levels of nonmarital fertility. Why are these areas unique, and what can they tell us about the significance of place in shaping fertility outcomes? Although much of the current research focuses on economic explanations, some attention has been given to other factors that play a role in influencing nonmarital fertility rates. These studies show that religion, migration, and education are also significant predictors of nonmartial fertility. This study builds …

Creating A Comparative Map Of Relative Power For Dc Arc Flash Methodologies, Andre Azares

Master's Theses

Although arc flash has been a concern amongst the electrical industry for many years, it is only relatively recently that standards by the IEEE have been established on calculating the amount of energy behind an arc flash event. However, these standards only apply to AC systems, where extensive testing and research have been performed. Although the NFPA has provided recommendations on how to calculate the incident energy for DC arc flash events, these have not become the defining standard like those seen for AC. One equation outlined in the NFPA70E, the Maximum Power Method, does provide engineers with a formula …
