Predicting Exercise Adherence In College Students Using A Self-Determination Theory Framework, Megan M. Clarke

Master's Theses

College is a pivotal time for weight gain and unhealthy behavior changes in many young adults. Decreases in physical activity are common in this age group and likely contribute to the 1.6 to 1.8 kg weight gain that is often observed in the first year of college. Identifying groups of students who are at high-risk for decreasing or discontinuing physical activity may help develop more targeted interventions. The present study explored physical activity patterns in the first semester of college and examined predictors of exercise decreases to levels below recommended daily values within a Self-Determination Theory framework. Incoming freshman (n=174; …

Dietary Protein Influences Paracellular Calcium Transport: Two Molecular Targets, Belinda M. Kotler

Master's Theses

The effect of dietary protein on bone health remains controversial. We have shown that increasing dietary protein increases calcium absorption in both humans and rats with no change in bone resorption. We used a rat model in which dietary protein increases intestinal calcium absorption and whole body calcium retention, to explore the molecular basis for this effect. Female Sprague-Dawley rats were fed a low (5%) or high (40%) protein diet for 7 days. On day 7, duodenal mucosa was harvested and total RNA isolated. Microarray analyses using these RNA samples identified 208 genes whose expression was at least 1.5 fold …

The Spatial Distribution Of K-Factor Values Across A Toposequence And A Soil Survey Map Unit, Jacqueline Elizabeth Tilligkeit

Master's Theses

Rivers and streams are adversely affected by an increase in sedimentation in their waters from eroding land. High sediment loads in streams can bury fish eggs and prevent hatching, increasing nutrients in the water causing algae blooms, or even contaminating the water with heavy metals carried in or on the aggregates. The erodibility of soil is valuable knowledge to all land users so that we may predict soil loss and its potential to pollute streams. This is done by using the Revised Universal Soil Loss Equation (RUSLE). By predicting soil loss from a given landscape, land managers can take mitigation …

Analysis Of Periapical Biopsies Submitted For Histopathological Evaluation: A Retrospective Study, Abdullah I. Alqaied

Master's Theses

Apical periodontitis is the most common pathological process in the periapical region. Disciplined clinical and radiographic evaluations and appropriate diagnostic tests can detect lesions related to apical periodontitis. Aside from this, lesions mimicking pulp-related pathology but unrelated to pulpal infection and necrosis are occasionally discovered in the periapical region. The objective of this study was two-fold: (1) to determine the prevalence of diverse periapically located pathological entities, and (2) to apply that information to evaluate the rationale for routine submission of surgically obtained tissue for histological examination and diagnosis. Methods: A 5-year retrospective analysis of pathology reports from the UCONN …

Evaluation Of Textural Properties Of Cooked Beef Batters, Lee M. Christensen

Master's Theses

In the meat science industry the primary method used to determine the binding capabilities of a raw material is to reference the binding index created by Carpenter and Saffle (1964). This index is primarily based on the emulsification capabilities of meats and does not consider texture. As texture is one of the principal factors in determining acceptability of foods (Bourne, 1978), a testing method that captures textural attributes of raw materials is essential. This work was developed to capture raw material texture and cooking loss in a relatively quick manner.

Textural properties of cooked beef batters using two different salt …

A Proteomic Analysis Of Differentiation In The Mammary Epithelium, Laura Therese Strand

Master's Theses

While a great deal is known about the changing hormonal environment and the structural development of the mammary gland from pregnancy to lactation, very little is known about the molecular mechanisms governing differentiation of the mammary epithelium into a milk-secreting phenotype. It is important to acknowledge the diversity among the mammary glands of different species in order to better understand applications in human health and the dairy industry. In this study, we examined global protein expression during two states of differentiation in mammary epithelial cells from two species: in vitro proliferating and differentiated MAC-T cells (a bovine immortal cell-line), and …

Effects Of Ovariectomy, Seasonal Changes, And Anatomical Position On The Compact Bone Remodeling As Seen In The Adult Ovine Model, Erica Wong

Master's Theses

The purpose of this study is to characterize the compact bone remodeling of the ovariectomized ewe and its effectiveness as an animal model for studies of postmenopausal osteoporosis. The use of animal models is a beneficial way to evaluate the effectiveness of medical devices and therapeutic agents for treating diseases. The ovine model is an attractive option because of its large size and similar bone remodeling to humans. However, this species, like most animals, does not undergo a natural menopause, making an ovariectomy necessary for studies of estrogen depletion. The OVX (ovariectomized) sheep has been widely accepted as a model …

American Pika (Ochotona Princeps): Persistence And Activity Patterns In A Changing Climate, Cody P. Massing

Master's Theses

An increasing amount of evidence suggests that as temperatures increase, montane animals are moving upward in elevation (IPCC 2007, Parmesan and Yohe 2003). As suitable habitats rise in elevation and then disappear altogether, these animals could be pushed to extinction. The American pika, Ochotona princeps, is a montane mammal that lives in western North America, usually at elevations above 1500 m (Smith and Weston 1990). Recent evidence suggests that pika population numbers are dropping in response to rising temperatures (Beever et al. 2010). The pika is a small herbivorous lagomorph, a relative of hares and rabbits. Its habitat is …

Supportive Housing For Families In Child Welfare: Client Characteristics And Risk Factors At Intake, Kellie G. Randall

Master's Theses

Many families involved in the child welfare system also face housing difficulties. Housing problems can disrupt family preservation efforts and delay reunifications from foster care. Supportive housing programs work with families who have dual vulnerabilities in housing and child welfare to integrate services and improve outcomes. Families in these programs might face barriers in addition to their housing and child welfare needs, but little is known about other risk factors in this population. This study uses a sample of 80 clients referred to a supportive housing for families program in order to examine the rate and prevalence of other risk …

Strawberry Growth, Yield, Fruit Nutrition, And Control Of Verticillium Wilt With Pre-Plant Soil Fumigants, Ozone, And Biological Control, Justin J. Scurich

Master's Theses

Verticillium wilt is a widespread soilborne disease of strawberry historically controlled by soil fumigation with methyl bromide (MB). MB was banned by the United Nations in 1995 and will be completely phased out by 2015. Research has concentrated on alternative methods of disease control without finding a single alternative able to replace MB in widespread disease control and yield increase. For the current study, strawberries were greenhouse grown in container pots filled with soil from both infested and non-infested areas of a commercial strawberry field in Watsonville, CA. Treatments included pre-plant soil fumigation with commercially available formulations of methyl bromide, …

Motivating Employees Through Thick And Thin: The Relationship Between Hospital Employee Aspirations And Body Mass Index, Amanda Kay Wentz

Master's Theses

The purpose of this study was to bridge the gap in the existing literature regarding the relationship between motivation and aspirations of obese and overweight employees. Based on data collected from 103 hospital employees, obese and overweight employees placed significantly lower importance on intrinsic aspirations than did their healthier counterparts. In addition, healthy, overweight, and obese employees all placed equal importance on extrinsic aspirations. The results of the study indicate that using intrinsic aspirations and rewards to motivate overweight and obese employees in a disease prevention program may be less effective than using an extrinsic reward system.

Growing Greens And Soiled Soil: Trends In Heavy Metal Contamination In Vegetable Gardens Of San Francisco, Jennifer Gorospe

Master's Theses

As urban dwellers prioritize eating locally grown foods to reduce environmental impacts, benefit the local economy, and bring fresh produce to the table, urban gardening has emerged as a popular approach to improving food security. Researchers have shown previously that urban landscapes can accumulate environmental toxins at levels that may be unsafe for human health, with socioeconomically disadvantaged communities often shouldering an unequal burden of exposure. In order to identify and predict likely risk to gardeners, in this study, soil samples from 91 vegetable gardens in the city of San Francisco were analyzed for 16 heavy metals. A majority of …
