Smokers were more likely to be older, have lower incomes, have lower BMI, and live with other smokers. Women with high social cohesion were less likely to smoke, although living in neighborhoods with higher social cohesion was not associated with smoking …

Simulated Microgravity Induces Epigenetic Changes, Nkem Osarume Azu B.S

Theses (Pre-2016)

DNA methylation is an epigenetic mechanism involved in gene expression regulation. Astronauts are constantly being exposed to different stress factors, which include radiation, microgravity and confinement. These environmental stressors are understood to increase bone loss, decrease muscle mass and reduce immune function. Our objective is to investigate the hypothesis that modeled microgravity induces gene expression through epigenetic changes. Abnormal epigenetic events have been reported in human diseases like cancers and immunological disorders. The purpose of this study was to determine whether modeled microgravity induces these epigenetic changes by examining the expression of the proteins known to regulate gene expression specifically …

Social Networking Site Use Among Caregivers Of Children With Autism Spectrum Disorders, Murad Moqbel, Lauren Little

Information Systems Faculty Publications

Caregivers of children with autism spectrum disorder (ASD) experience higher levels of stress relative to those of children with other developmental disabilities and typical development. To date, little research has empirically examined the relationship between social supports, social networking site (SNS) use, and stress among caregivers of children with ASD. Using the resiliency model of family stress, adjustment, and adaptation as a theoretical framework, we explore the links between perceived social supports, SNS use, and stress among caregivers of children with ASD. We do this by conducting a crosssectional research design and using a structural equation modeling statistical approach. Practical …

The Relationship Between Labor Unions And Safety In Us Airlines: Is There A "Union Effect?", Renee Catherine Zapf

Theses and Dissertations

Every airline union claims to work for safety and presents anecdotes where greater airline safety has been achieved through union efforts. The effect unionization has on safety outcomes in U.S. commercial airlines, however, wasn’t found to be previously tested. Studies have shown that in industries such as coal mining, retail, and construction, unionization does lead to an increase in safety. This study evaluated the safety rates of 15 major US commercial airlines to compare the difference between unionized and non- unionized airlines. These safety rates were compared based on if and how long each airline’s pilots and flight attendants have …

Identifying The Optimum Temperature For The Most Efficient Photosynthetic Rate In The Scleractinian Coral Stylophora Pistillata In The Gulf Of Eilat, Red Sea, Eleanor Vaughan

The Plymouth Student Scientist

The Gulf of Eilat (GoE), Red Sea, is a unique region that harbours one of the northernmost coral reef ecosystems in the world, and possesses high biodiversity and endemism. Global climate change is associated with an increase in sea surface temperatures that can lead to bleaching and mortality in scleractinian corals. However the corals in the GoE differ to other reefs at the same high latitude because of their unique resilience to thermal stress, which suggests that this region may be a refuge for reefs under a period of environmental change. This study aimed to determine the temperature at which …

A Comparative Analysis Of Instructional Techniques Toward Long-Term Positive Ergonomics Transformation For The Early Career Sonographer, Jody L. Hancock

Masters Theses and Doctoral Dissertations

The past two decades have demonstrated sonographer work-related musculoskeletal disorder (WRMSD) rates between 80.0 to 90.4%. A surprising revelation made by sonographers was that educators were not perceived as the primary providers of ergonomics instruction. For these reasons, a mixed methods study was performed, involving a causal-comparative component with a longitudinal perspective, a quasi-experimental element, and limited observations and interviews. The study followed four years of sonography graduates through the early career scan period, comparing transmissional, transactional, and transformational learning results. The study’s goal was to determine whether transformative ergonomics learning in a collaborative and reflective environment could demonstrate a …

The Relationship Between Freshmen Student Retention And Use Of An Online Parent Portal, Brandy Mallory Cartmell

Using Network Clustering To Predict Copy Number Variations Associated With Health Disparities, Yi Jiang

Masters Theses and Doctoral Dissertations

Substantial health disparities exist between African Americans and Caucasians in the United States. Copy number variations (CNVs) are one form of human genetic variations that have been linked with complex diseases and often occur at different frequencies among African Americans and Caucasian populations. In this study, we aimed to investigate whether CNVs with differential population frequencies can contribute to health disparities from the perspective of gene networks. We inferred network clusters from two different human gene/protein networks. We then evaluated each network cluster for the occurrences of known pathogenic genes and genes located in CNVs with different population frequencies, and …

This study evaluated the impact of participation in a social network site (SNS) on the stress levels of single mothers for the purpose of using updated resources to replicate and expand upon the initial work of Dunham et al. (1998). This study sought to answer the following research questions: Does participation in …

Mystical Experience As Predictor Of Domains Of Religious And Spiritual Self Identification: Empirical And Theoretical Considerations, Sara E. Hall-Mckane

Masters Theses and Doctoral Dissertations

The concept of spirituality has emerged as a major focal point in both the theoretical and empirical study of religion. Whether the emergence of spirituality is a dimension of religion or a separate and distinct construct has been the subject of much debate among scholars. The philosophical arguments proposed on either side have underscored the need for further research into just what spirituality is and is not. An ongoing transition from a more religious to a more spiritual self identification is evident at least in the United States (Roof & Greer, 1993, 1999; Pargament, 1999). Using the data collected from …

Fatigue Damage Prognosis Of Internal Delamination In Composite Plates Under Cyclic Compression Loadings Using Affine Arithmetic As Uncertainty Propagation Tool, Audrey J-M Gbaguidi

Doctoral Dissertations and Master's Theses

Structural health monitoring (SHM) has become indispensable for reducing maintenance costs and increasing the in-service capacity of a structure. The increased use of lightweight composite materials in aircraft structures drastically increased the effects of fatigue induced damage on their critical structural components and thus the necessity to predict the remaining life of those components. Damage prognosis, one of the least investigated fields in SHM, uses the current damage state of the system to forecast its future performance by estimating the expected loading environments. A successful damage prediction model requires the integration of technologies in areas like measurements, materials science, mechanics …
