The Longitudinal Relationship Between Moderate Alcohol Use And Cognitive Aging Among Older Adults., Danielle Herring Jan 2016

The Longitudinal Relationship Between Moderate Alcohol Use And Cognitive Aging Among Older Adults., Danielle Herring

Electronic Theses and Dissertations

Cognitive aging appears inconsistent across cognitive domains, indicating that domains may not all decline at the same rate across individuals. Individual trajectories of cognitive aging can vary widely and are affected by numerous lifestyle and health factors. Alcohol use among older adults is known to confer both health risks, typically related to excessive use, and protective effects, often associated with moderate consumption. Moderate alcohol use has been linked with better cognitive functioning as well as a decrease in cardiovascular mortality and systemic inflammation, as compared to heavy or abstinent users. Given that extant research has identified C-reactive protein (CRP) as …

Neurological Profile Of Older Apoe-Pon1 Double Knockout Mice, Connie Mitra Jan 2016

Neurological Profile Of Older Apoe-Pon1 Double Knockout Mice, Connie Mitra

Electronic Theses and Dissertations

Atherosclerosis is a cardiovascular disease where plaques made up of lipids in the form of cholesterol ester build up in the carotid and innominate arteries that supply blood to the brain. Accumulation of the plaques limit the flow of blood and nutrients to the brain, leading to diminished oxygen supply, increased oxidative stress and cell death. All these have been implicated in Alzheimer's disease (AD). Alzheimer's disease, a chronic, progressive, age related neurodegenerative disorder is the most common form of dementia in the elderly accounting for 60-80% of the cases. Clinically, Alzheimer's disease is characterized by loss of memory, damage …

An Investigation Of The Biomechanical Implications Of Lower Limb Fractures And Leg Length Disparity, Elizabeth Mills Jan 2016

An Investigation Of The Biomechanical Implications Of Lower Limb Fractures And Leg Length Disparity, Elizabeth Mills

Electronic Theses and Dissertations

One of the primary goals of biological anthropology is to develop an accurate understanding of human anatomy, health, disease, and injury in both modern and archaeological populations. Paleopathological analyses are a fruitful means of identifying disease and injury in skeletal assemblages, but the individual long-term biomechanical effects associated with pathological conditions have not yet been adequately explored in the literature. Leg fractures are a common pathological condition in both modern and archaeological populations, the effects of which may alter the biomechanics of gait. A growing body of clinical literature demonstrates that abnormal ambulatory function may have far-reaching effects in the …

Transforming The Aquatic Urban Landscape: Nutrient Status And Management Of Stormwater Basins, Lindsay Skovira Jan 2016

Transforming The Aquatic Urban Landscape: Nutrient Status And Management Of Stormwater Basins, Lindsay Skovira

Electronic Theses and Dissertations

Urbanization is a largely irreversible anthropogenic change that degrades environmental quality, including aquatic ecosystems. Stormwater ponds are a popular best management practice (BMP) to mitigate the effects of urban land use on downstream water bodies and contribute significantly to the total area of aquatic ecosystems in some urban watersheds. My research investigated the distribution of stormwater ponds and examined how different urban land uses influenced biophysicochemical conditions and management of those ponds in a rapidly developing suburban watershed in the Econlockhatchee River basin in Florida, USA. I evaluated limnological and ecological parameters in randomly-selected ponds distributed among three urban land-use …

Individual Differences In Trust Toward Robotic Assistants, Tracy Sanders Jan 2016

Individual Differences In Trust Toward Robotic Assistants, Tracy Sanders

Electronic Theses and Dissertations

This work on trust in human-robot interaction describes a series of three experiments from which a series of predictive models are developed. Previous work in trust and robotics has examined HRI components related to robots extensively, but there has been little research to quantify the influence of individual differences in trust on HRI. The present work seeks to fill that void by measuring individual differences across a variety of conditions, including differences in robot characteristics and environments. The models produced indicate that the main individual factors predicting trust in robotics include pre-existing attitudes towards robots, interpersonal trust, and personality traits.

Navigating Sociotechnical Power Structures: Dynamics Of Conflict In World Of Warcraft's Player Versus Player Events, Rachael Root

Electronic Theses and Dissertations

As a result of technological advancement and exponential increases in global access, cross-disciplinary research has recently turned to digital online video games. Most anthropological research within this area has centered around player self-identification, gender construction, and gaming communities. Yet many interactions occur at nodes of dynamic conflict where agentic players navigate intersections of power, which are unaddressed in the scholarly corpus. By utilizing ethnographic methods in World of Warcraft's player versus player events, I examine resources, relationships, and tools that underpin player actions and understandings. My findings reveal layered and dynamic patterns of sociotechnical conflict. Players' geographical location impacts access …

Study Of Polychlorinated Biphenyl Dechlorination By Zero Valent Magnesium With And Without Activated Carbon In Acidified Ethanol-Ethyl Lactate System, Fiona Zullo

Electronic Theses and Dissertations

Polychlorinated biphenyls (PCBs) are synthetic organic chemicals that ca de detected in the environment worldwide. PCBs were banned in the U.S in 1979 owing to their toxicity and persistence in the environment. Today PCBs are classified as human carcinogens and are among the top ten of the U.S Environmental Protection Agency's (EPA) most toxic chemicals. Many researchers have shown soil to be contaminated with PCBs at concentrations as high as 750 ppm. Given the toxicity of PCBs, there is an urgent need to extract and degrade such chemicals from contaminated soil in a cost effective way. Prior work revealed a …

Provider Recommendation Of Hpv Vaccination: Bridging The Intention-Behavior Gap, Erica Landis Jan 2016

Provider Recommendation Of Hpv Vaccination: Bridging The Intention-Behavior Gap, Erica Landis

Electronic Theses and Dissertations

The present study, guided by preproduction formative research principles, employed in-depth interviews and a brief survey with pediatric healthcare providers (N=15) to investigate the consistency between behavioral intention to strongly recommend the HPV vaccine, and implementation of the actual behavior. Specifically, the Integrative Model of Behavioral Prediction (IMBP) was used as a framework to examine the impact of skills and environmental constraints on that behavioral intention-behavioral performance relationship. Results suggest providers intend to strongly recommend the HPV vaccine at a high level, but actually recommend the vaccine with a slightly lesser frequency. A thematic analysis of interview transcripts yielded a …

Building A Foundation For Goal-Attainment And Problem-Solving In Interdisciplinary Studies: Reimagining Web-Based Core Curriculum Through A Classical Lens, Said Jardaneh

Electronic Theses and Dissertations

The core curriculum of interdisciplinary studies undergraduate programs represents interdisciplinarity as a consciously applied process, whether individually or collaboratively, of drawing and integrating insights from various disciplinary perspectives toward complex problem-solving and innovation. At the front-end of these programs students are often introduced to interdisciplinarity through terminology, metaphors, concepts, and context that are intended to familiarize them with the process. This initiation usually precedes what will ultimately entail a limited number of upper-division courses within the several disciplines or areas that will encompass a unique plan of study characterized by its breadth. The philosophy underlying current pedagogy in interdisciplinary studies …

The Reproducibility And Validity Of Using The Dmax Method To Predict Physical Working Capacity At Fatigue Threshold, Joshua Riffe Jan 2016

The Reproducibility And Validity Of Using The Dmax Method To Predict Physical Working Capacity At Fatigue Threshold, Joshua Riffe

Electronic Theses and Dissertations

Although the original (ORG) physical working capacity at fatigue threshold (PWCFT) assessment has demonstrated strong reliability and sensitivity to training and/or nutritional interventions, limitations may exist regarding the method of PWCFT estimation. However, a relatively new mathematical method, called Dmax, has been shown to be objective and reliable when estimating metabolic and neuromuscular fatigue thresholds. To date, however, no study has examined whether the Dmax method for estimating the work rate at PWCFT is similar to the ORG method. PURPOSE: The purpose of this study is to evaluate the reliability and validity of the Dmax-EMG method for estimating and tracking …

Inclusion: A Question Of Practice, Stance, Values And Culture, June Sellers Jan 2016

Inclusion: A Question Of Practice, Stance, Values And Culture, June Sellers

Electronic Theses and Dissertations

Exclusionary practices based on a deficit perspective of disability are not supported by law and are inconsistent with the rigorous standards for teaching, learning, and accountability in our public schools. Moreover, consequences of failed change will continue to have significant negative effects on the performance of educational organizations. The purpose of this mixed-methods phenomenological research (MMPR) study was to explore the lived experience of teachers who identify as champions of inclusion, including their views, perceptions and appraisal of the status of inclusion in a large urban school system. The research questions were designed to generate insight and recommendations for establishing …

Role Of Klf8-Cxcr4 Signaling In Breast Cancer Metastasis, Debarati Mukherjee Jan 2016

Role Of Klf8-Cxcr4 Signaling In Breast Cancer Metastasis, Debarati Mukherjee

Electronic Theses and Dissertations

Krüppel-like factor 8 (KLF8) has been strongly implicated in breast cancer metastasis. However, the underlying mechanisms remain largely unknown. In this study we report a novel signaling from KLF8 to C-X-C cytokine receptor type 4 (CXCR4) in breast cancer. Overexpression of KLF8 in MCF-10A cells induced CXCR4 expression at both mRNA and protein levels. This induction was well correlated with increased Boyden chamber migration, matrigel invasion and transendothelial migration (TEM) of the cells towards the ligand CXCL12. On the other hand, knockdown of KLF8 in MDA-MB-231 cells reduced CXCR4 expression associated with decreased cell migration, invasion and TEM towards CXCL12. …

Resistance Exercise Elicits Selective Mobilization And Adhesion Characteristics Of Granulocytes And Monocyte Subsets, Adam Jajtner Jan 2016

Resistance Exercise Elicits Selective Mobilization And Adhesion Characteristics Of Granulocytes And Monocyte Subsets, Adam Jajtner

Electronic Theses and Dissertations

Resistance exercise eliciting muscle damage results in an immune response, leading to increases in circulating cytokines, and immune cell mobilization. Classical monocytes respond to muscle damage, however, little is known about the intermediate or nonclassical monocyte response to resistance exercise. Moreover, the impact of polyphenol supplementation in conjunction with resistance exercise on the innate immune response is unknown. The purpose of this study was to examine the immune response following resistance exercise with (PPB) and without (PL) polyphenol supplementation. Thirty-nine untrained men were randomized into three groups: PPB (n=13, 21.8±2.5yrs, 171.2±5.5cm, 71.2±8.2kg), PL (n=15, 21.6±2.5yrs, 176.5±4.9cm, 84.0±15.7kg) or a control …

Team Cohesion In The Restaurant Industry: The Influence Of Core Evaluations, Marissa Orlowski Jan 2016

Team Cohesion In The Restaurant Industry: The Influence Of Core Evaluations, Marissa Orlowski

Electronic Theses and Dissertations

Team cohesion has been clearly established in the literature as an essential component of effective work teams, yet little research has been conducted in regard to what factors lead to cohesion within a restaurant management team. What is currently known about the antecedents of cohesion indicates that it emerges from individual team member attitudes and perceptions as a collective property of the team. This, in turn, suggests cohesion is influenced by the dispositional traits of team members. The core evaluations construct, which represents a model of dispositional traits existing within each individual at the most basic level, offers implications for …

Falling Behind In Pay: A Longitudinal Test Of Equity Theory Among Florida Municipal Police Agencies' Salaries, Robert Lord Jan 2016

Falling Behind In Pay: A Longitudinal Test Of Equity Theory Among Florida Municipal Police Agencies' Salaries, Robert Lord

Electronic Theses and Dissertations

Prior research has found equity theory explains employee responses to falling wages in relation to other comparable workers. The present research attempts to contribute to the criminal justice literature by directly testing equity theory within the policing context, something no study has done to date. Applied to policing, equity theory predicts sworn officers employed by departments with falling or inequitable salaries (i.e., their salaries fail to keep up with those at other regional agencies) will reduce their work input (i.e., discretionary arrests) and/or quit in higher numbers than before (i.e., increase attrition). The present study also attempts to quantify how …

Attitudes Toward Cohabitation: A Cross Sectional Study, Kensington Shields-Dutton Jan 2016

Attitudes Toward Cohabitation: A Cross Sectional Study, Kensington Shields-Dutton

Electronic Theses and Dissertations

Cohabitation and attitudes toward cohabitation have been of interest to social scientists since the 1970s. Early research on cohabitation concentrated on college aged students enrolled at institutions of higher learning. This trend was due to convenience sampling (Trost, 1978). Later research demonstrated the college population represented less than half of the total number of cohabitating persons. With the growth in numbers of persons who are choosing to cohabitate versus marrying, this study examines current attitudes towards cohabitation. This research augments the existing literature on attitudes toward cohabitation in the following ways: (1) it updates the current research on the attitudes …

Kidron Road And Other Stories, Jason Molohon Jan 2016

Kidron Road And Other Stories, Jason Molohon

Electronic Theses and Dissertations

Kidron Road and Other Stories is a collection of fiction that ranges from the soberly tragic to the magically real. The characters in each selection are molded by their choices, the choices of others, and the cruel whims of fate. I am fascinated by the way fatalism and free will intersect in the human experience. Therefore, my work often explores the paradoxical way lives are molded by past decisions while, at the same time, those decisions seem determined by outside forces.

Mothers' Temperament, Adverse Childhood Experiences, And Psychological Symptoms: How Are Enduring Maternal Characteristics Related To Mothers' Perceptions Of Children's Temperament, Behavior Problems, And Adaptive Functioning?, Ellen Kolomeyer Jan 2016

Mothers' Temperament, Adverse Childhood Experiences, And Psychological Symptoms: How Are Enduring Maternal Characteristics Related To Mothers' Perceptions Of Children's Temperament, Behavior Problems, And Adaptive Functioning?, Ellen Kolomeyer

Electronic Theses and Dissertations

Extant literature documented the impact of mothers' characteristics and parenting behaviors on young children's psychosocial outcomes. Additionally, previous studies demonstrated the importance of mothers' adverse childhood experiences in the relationships among some of these constructs. To expand on the existing knowledge, the present study examined the relationships among mothers' temperament, reflective functioning, attributions, and specific parenting behaviors, with reflective functioning and attributions serving as two potential mediating variables in these relationships. A community sample of 224 diverse mothers of young children who were between 2- to 5-years of age rated their own adverse childhood experiences, temperament, reflective functioning, attributions, specific …

Giving Theatrical Life, Quentin Darrington Jan 2016

Giving Theatrical Life, Quentin Darrington

Electronic Theses and Dissertations

An experience, early in my life, at the Tampa Bay Performing Arts Center opened my eyes to the transformative power of Theatre - it would shape my ambitions for performance, inform the choices I made about my acting career, and impel my passions. That single moment had a profound and lasting effect on my soul, one that would ultimately point me to the purpose of "me;" but what exactly was it? What transaction occurred between the performers on stage, and myself, and others in attendance that evening? My life as an actor has been an incredible journey of growth. Over …

Christ On The Postmodern Stage: Debunking Christian Metanarrative Through Contemporary Passion Plays, Joseph Dambrosi Jan 2016

Christ On The Postmodern Stage: Debunking Christian Metanarrative Through Contemporary Passion Plays, Joseph Dambrosi

Electronic Theses and Dissertations

As a Christian theatre artist with a conservative upbringing, I continually seek to discover the role of postmodernism in faith and how this intersection correlates with theatre in a postmodern society. In a profession that constantly challenges the status quo of Christian living, and a faith that frowns upon most "secular" behavior, I find myself in a position of questioning the connection between these two components of my life. Furthermore, I am troubled by the exclusive nature of the evangelical Christian community for people who do not meet its expectations of absolute truth—namely, the treatment of the LGBTQ+ community and …
