Health Beliefs And Socio-Cultural Factors That Predict Cervical Cancer Screening Behaviors Among Hispanic Women In Seven Cities In The Upstate Of South Carolina, Arelis Moore De Peralta

All Dissertations

Cervical cancer is one of the most common reproductive cancers among women in the United States. The incidence and mortality rates of cervical cancer among Hispanic women in the U.S. are almost two times higher than non-Hispanic Whites. Cervical cancer screening is associated with early cervical cancer detection and, thus, with reductions in cancer morbidity and mortality. In Hispanic populations, where cancer rates are disproportionately high, it is important to conduct research that accounts for the influence of culture in health-seeking behaviors. The purpose of this study was to use the Health Belief Model (HBM) as a theoretical framework to …

Arsenic is a toxicant commonly found in water systems around the world. Evidence from epidemiological studies indicates that chronic arsenic exposure can result in cancer, central nervous system and sensory deficits, effects on development, and neuromuscular deficits. However, the molecular mechanism of arsenic's toxicity remains largely unclear. In this study, both C2C12 mouse myoblast cells and mouse embryonic stem cells (mESCs) were used as models of arsenic mediated developmental toxicity in humans to investigate the effects of sodium arsenite on cellular differentiation.
Results from our first and second studies indicate that exposure of 20nM sodium arsenite to C2C12 mouse myocyte …

Impacts Of Psychotropic Pharmaceuticals On Hybrid Striped Bass: Altered Predation Behavior As A Function Of Changes In Brain Chemistry, Joseph Bisesi

All Dissertations

Advances in Analytical Chemistry have led to the detection of low concentrations of pharmaceuticals and personal care products (PPCPs) in wastewater treatment plant effluents as well as their receiving waters. Antidepressants are routinely found among these contaminants, but have been shown to be relatively non-toxic at environmentally measured concentrations using traditional toxicity testing techniques. The neurochemical mode of action of antidepressants warrants investigation of the effects these chemicals may have on fish behavior due to the highly conserved nature of neurotransmitter transporter targets. Using a predator prey bioassay designed in our laboratory, previous studies has shown that the antidepressant fluoxetine …

Characterizing Mechanical Heterogeneity In Cardiovascular Cells, Sandra Deitch

All Dissertations

Most tissue-level mechanical models assume homogeneous mechanical properties within a single cell type. However, measurements of cellular mechanical properties show large variability in whole-cell mechanical properties between cells from a single population. This heterogeneity has been observed in many cell populations and with several measurement techniques but the sources are not yet fully understood. Cell mechanical properties are directly related to the composition and organization of the cytoskeleton, which is physically coupled to neighboring cells through adherens junctions and to underlying matrix scaffolds through focal adhesion complexes. As such, we believe that this high level of heterogeneity can be attributed …

Direct And Indirect Effects Of Social Class On Career Expectations And Likelihood Of Compromise In An Adolescent Sample, Sarah Wilson

Dissertations

The current study investigated the application of classic attainment models, both direct and indirect effects, in the predication of career expectations and likelihood of compromise. The results indicated that among high school students (N=200) in grades 10-12 there is no direct effect of socio economic status (SES; as measured by parent education and occupation) on career compromise (aspirations exceeding expectations). Similarly, educational expectations are not directly related to the compromise of occupational expectations. Results of exploratory analysis suggest that career compromise is best explained by academic achievement and parent expectations. In an analysis of the process by which social class …

Detection-Assisted Object Tracking By Mobile Cameras, Li He

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

Tracking-by-detection is a class of new tracking approaches that utilizes recent development of object detection algorithms. This type of approach performs object detection for each frame and uses data association algorithms to associate new observations to existing targets. Inspired by the core idea of the tracking-by-detection framework, we propose a new framework called detection-assisted tracking where object detection algorithm provides help to the tracking algorithm when such help is necessary; thus object detection, a very time consuming task, is performed only when needed. The proposed framework is also able to handle complicated scenarios where cameras are allowed to move, and …

Influence Of Affluence On Sustainable Housing In Mysore, India, Bk Satish, J Brennan, R Pedreschi

School of Art, Design and Architecture

Mysore, the second largest city in the state of Karnataka, India, can be identified as an early adopter of sustainable design practices. Between 1903 and 1947 the use of local construction materials, the Swadeshi movement of 1905, robust planning and clear legislation resulted in sustainable urban development. However, post-colonial development fuelled by economic globalisation after the 1980s has transformed perceptions of the house among the growing middle class, becoming a commodity to demonstrate affluence and status. This paper examines the impact of changing social and cultural values on the aspirations of the growing middle classes on sustainable housing and neighbourhood …

Investigating The Role Of God Attachment, Adult Attachment And Emotion Regulation In Binge Eating, Angela Charpia Weaver

Doctoral Dissertations and Projects

Using a cross-sectional, self-report research design, this study examined a non-clinical population of 175 college women between the ages of 18-28 at a private, Christian university. A Pearson correlation matrix confirmed significant linear relationships between binge eating symptoms, emotion regulation, adult attachment insecurity and God attachment insecurity. A hierarchical multiple regression model determined that God attachment insecurity does not contribute unique variance toward binge eating symptoms after controlling for emotion regulation and adult attachment insecurity. Because God attachment insecurity was correlated to emotion regulation and adult attachment insecurity, and weakly correlated to binge eating symptoms without contributing unique variance, this …

What Is Securities Fraud?, Samuel W. Buell

Duke Law Journal

As Rule 10b-5 approaches the age of seventy, deep familiarity with this supremely potent and consequential provision of American administrative law has obscured its lack of clear conceptual content. The rule, as written, interpreted, and enforced, is missing a fully developed connection to—of all things—fraud. Fraud is difficult to define. Several approaches are plausible. But the law of securities fraud, and much of the commentary about that body of law, has neither attempted such a definition nor acknowledged its necessity to the coherence and effectiveness of the doctrine.

Securities fraud’s lack of mooring in a fully developed concept of fraud …

Dna As Patentable Subject Matter And A Narrow Framework For Addressing The Perceived Problems Caused By Gene Patents, Stephen H. Schilling

Duke Law Journal

Concerns about the alleged harmful effects of gene patents— including hindered research and innovation and impeded patient access to high-quality genetic diagnostic tests—have resulted in overreactions from the public and throughout the legal profession. These overreactions are exemplified by Association for Molecular Pathology v. U.S. Patent and Trademark Office, a 2010 case in the Southern District of New York that held that isolated DNA is unpatentable subject matter under 35 U.S.C. § 101. The problem with these responses is that they fail to adequately consider the role that gene patents and patents on similar biomolecules play in facilitating investment in …

Does Non-Steroidal Anti-Inflammatory Drug (Nsaid) Use Affect Dementia Progression And Survival Rates In Alzheimer's Disease? The Cache County Study, Trevor R. Buckley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alzheimer's disease (AD) has multiple factors that contribute to the disease process. Among these is a state of chronic inflammation that is endured by the brain during the aging process. The use of non-steroidal anti-inflammatory drugs (NSAIDs) decreases the amount of neuroinflammation sustained by the brain, and greater levels of NSAID use have been demonstrated to be associated with decreased probability of developing AD. This study looked at whether greater rates of NSAID use were also associated with decreased rates of cognitive and funtional decline and survival in a population-based sample of persons with AD. Linear mixed models failed to …

Environmental Sensor Anomaly Detection Using Learning Machines, Erick F. Conde

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The search for improvements in the quality assurance/quality control (QA/QC) of real-time environmental measurements has been a field well exploited in recent years. These measurements describe actual environmental conditions and processes that provide relevant information upon which water quality management decisions are based. In situ sensors (located at the site of interest) are commonly used for such real-time measurement purposes. However, the performance of these types of sensors can be affected by such things as human factors, lack of necessary maintenance, flaws on the transmission line or any part of the sensor, and unexpected changes in the sensors surrounding conditions. …

In the first study, three landscape treatments integrating different types of plants—woody, herbaceous perennial, turf—and putative water use classifications—Mesic, Mixed, Xeric—were grown in large drainage lysimeters. Each landscape plot was divided into woody, turf, and herbaceous perennial plant hydrozones and irrigated for optimum water status over two years, with water use measured using a water balance approach. For woody plants and herbaceous perennials, canopy cover, rather than plant type or …

Seasonal Influenza Vaccination Disparities Between U.S. Non-Hispanic Whites And Hispanics, 2000-2009, Andrew E. Burger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Seasonal influenza produces substantial disease within the United States every year. Despite the availability of safe and effective vaccines for influenza, millions of individuals go unvaccinated each flu season, with notable differences across racial/ethnic groups. Using the Behavioral Risk Factor Surveillance System (BRFSS), I examine vaccination rates among non-Hispanic whites and Hispanics during the 2000-2009 influenza seasons. After developing a new method that addresses shortcomings of BRFSS vaccination measures, I find that non-Hispanic whites exhibit higher vaccination rates than Hispanics. Through a series of logistic regression models I show that the disparities between non-Hispanic whites and Hispanics narrow after controlling …
