Is This Going To Be The End? Understanding Problematic Integration Among Appalachian Patients In Colorectal Cancer Screening Navigation, Audrey Smith Bachman

Theses and Dissertations--Communication

Colorectal cancer (CRC) is preventable through regular screening; however, incidence and mortality rates in Appalachia are among the highest in the United States. Public health programs and interventions meant to mitigate the higher CRC burden and increase screening rates are ongoing in the U.S. and Appalachia. In continuing the efforts to reduce the burden of CRC in Appalachian communities, this dissertation uses a two-part study to investigate communication practices relative to problematic integration and health beliefs in CRC screening conversations from the perspective of both patients and patient navigators in the region. As part of efforts directed by the Rural …

Motivating The Protection Of Others: A Theoretical Extension And Empirical Test Of Compassion Appeals, Erin B. Hester

Theses and Dissertations--Communication

The term “wicked problems” is used to describe a constellation of social issues that are deeply entangled (Rittel & Webber, 1973). Although these social messes affect everyone in society, some people suffer more than others (Ackoff, 1974). Nevertheless, tackling wicked problems begins with recognizing our shared responsibility to ease the misfortune of others (Rittel & Webber, 1973). As such, they provide an ideal context to investigate the persuasive effectiveness of messages that encourage the protection of others (i.e., other-protection messages). Wicked problems, such as the opioid crisis and food insecurity, need strategies that compel individuals to engage in prosocial action …

From Fear To Action: Exploring The Role Of Emotion During Imminent Threat Events Using The Extended Parallel Process Model, Michele K. Olson

Theses and Dissertations--Communication

The extended parallel process model (EPPM) is a popular health and risk communication theory that explicates the relationship between perceived threat, perceived efficacy, fear, and adaptive and maladaptive responses. This study examines the EPPM in an imminent threat context and focuses on how warning message content influences EPPM perceptions and how these perceptions, in turn, influence both protective action and information seeking intentions.

The first objective of this study focuses on applying the EPPM to an imminent threat context by designing EPPM informed tornado and flash flood warning messages. After message pretesting with 42 undergraduate students, 312 undergraduate students completed …

Applying The Causal Network Model To Advance Care Planning Messages, Katherine Leigh Harville

Theses and Dissertations--Communication

The process of advance care planning often involves conversations that focus on worst case scenarios and discussions of end-of-life, which makes the topic a daunting one. Most of these conversations occur with older adults or individuals who are seriously ill. However, advance care planning is of importance to those who are healthy, young adults as well. Narrative messages could help simplify the process of approaching such conversations and provide tools for conducting them in a more effective manner.

The proposed study makes use of the causal network model, a model that proposes that the location of information within narratives impacts …

Authentically Advocating: Public Relations' Role In Social Issues Management, Gabrielle Leigh Dudgeon

Theses and Dissertations--Communication

Now more than ever, organizations utilize public relations to build, maintain, and even strengthen relationships with internal and external stakeholders. Many public relations strategies and tactics serve to bridge an organization’s interests with those of their publics, while also building, maintaining, and strengthening trust. Social issues management is one of the tools that has the potential to build long-term trust and commitment. Public relations practitioners have recognized this opportunity, and most engage in social issues management in a variety of ways to strengthen their organizations while also contributing to society (Fall, 2006). This double-edge tool can create long- lasting impact …

Is Embedded Behavioral Health Embedded Enough? Why Behavioral Health Officers Should Be Battalion Level Assets, Amy Hernandez

DSW Capstone Projects

Due to the long-lasting military operations in Iraq and Afghanistan, current military members are likely to have deployed multiple times and have experienced chronic high-intensity stress. Numerous studies have demonstrated that military service members are at elevated risk for various psychiatric problems and substantially underutilize mental health services. This capstone consists of a series of academic papers: systematic review, conceptualization paper and practical application paper aimed at exploring barriers to care and conceptualizing possible solutions. The research question guiding the systematic review is what actual or perceived barrier to care has the most significant impact on solider under-utilization rates of …

The goal was to determine if these shifts in rumen fermentation contribute to the Programmed Nutrition response observed in vivo. This study also analyzes how different levels of α-amylase (Amaize)supplementation impacts feedstuff degradation and utilization in vitro. In vivo experiment used eight steers in a replicated …

Twenty-First Century Adaptations Of Early Twentieth Century American Protest Literature, Kathryn J. Mcclain

Theses and Dissertations--English

Twenty-First Century Adaptations of Early Twentieth Century American Protest Literature examines the resurgence of didactic political literature in the United States during the 21st century, specifically adaptations of early 20th century American leftist protest works by authors such as Upton Sinclair, Jack London, and Richard Wright. While the most political aspects of these writers’ fiction are often either criticized as too politically overt – such as Sinclair’s The Jungle and Wright’s Native Son – or forgotten in favor of an author’s perceived literary merit – London’s The Iron Heel in comparison to his other works like Call of the Wild …

Three Essays On Governance, Inequality, And Social Equity, Sarah Ausmus Smith

Theses and Dissertations--Public Policy and Administration

Comprised of three essays, my dissertation is linked by a common focus: the relationship between state or local governance arrangements and inequality or facets of social equity. I draw upon a range of literatures to motivate my research questions and inform my methodologies—welfare and social policy, public economics, intergovernmental relations, public finance and management.

In the first essay, I ask: does localizing welfare governance impact geospatial access to the social safety net? This is an important question because proximity is highly salient to program utilization. I geocode the location of human services nonprofits from tax filings in eight states using …

Demand System Analysis Of Beer In The U.S. Market, Laxmi Devi Adhikari

Theses and Dissertations--Agricultural Economics

The onset of the COVID-19 pandemic has stimulated remarkable changes in consumer purchasing and consumption behavior of food and beverages. This inherently raises the question of what the demand for beer differentiated by brands in the U.S. during the pandemic is? To answer this question, we used the recent Nielsen scanner data and employed the Linear Approximated Almost Ideal Demand System (LA/AIDS) model to jointly estimate the demand for the five major brands: Budweiser, Coors, Corona, Heineken, and Miller, as well as remaining brands combined. Our results suggest the sales of Corona and Heineken increased during the pandemic. After controlling …

Consumer Measures Of Local Food System Performance And Shopping Behavior Across Covid, Azita Varziri

Theses and Dissertations--Agricultural Economics

This dissertation consists of three essays: In the first essay, we utilize a Principal Component Analysis (PCA) to measure the residents’ perceptions of the local food system performance. Local food system (LFS) components are classified into related measures that may help explain the overall performance scores provided. LFS performance measures are explored across 15 different communities in the U.S. South. The second essay explores the awareness and performance differences toward farmers markets, including the markets themselves and the corresponding local food product quality, product diversity, and markets infrastructure across different age-range groups and community sizes in Southern states.

Across seven counties in Kentucky, North Carolina, and Maryland, 183 participants were surveyed about their usage of online grocery shopping before and after COVID-19, their opinions about online grocery shopping, their dietary intake, and food security. Survey answers were stratified between SNAP and non-SNAP recipients and urban and rural …

Sex Dimorphism In Hematopoiesis And Bone Marrow Niche, Xiaojing Cui

Theses and Dissertations--Toxicology and Cancer Biology

Hematopoietic stem cells (HSC), which are a rare population of cells existing in human circulating blood and bone marrow, can form the whole-blood system by their self-renewal capacity and differentiation ability. Sex dimorphism can be found in hematopoietic stem and progenitor cells, and in the development of hematopoietic lineages. Also, males are at higher risk and have a worse prognosis for most hematologic malignancies than females. Under normal conditions, the number of circulating progenitor cells in women is lower than in men. Furthermore, female mice have a higher rate of HSC division than male mice. A dramatic gender difference exists …

The Pet’S ‘Perfect Bowl’: Environmental And Welfare Discourse In Alternative Pet Food Movements, Carly Baker

Theses and Dissertations--Geography

Marketing ‘sustainable and humane’ super-premium dog kibble has emerged alongside alternative food movements (AFM). Unfortunately, super-premium pet-food comprised of ‘high-quality’ protein is at odds with sustainability and affect for particular animals. This study analyzed social and geographical (mis)representations of nonhumans in the pet-food commodity chain by tracing how knowledge and value is produced, and mapping the geography of Open Farm dog food. I assess these geographies and discourses and I identify the following: (1) sustainability claims focus on transportation and packaging, ignoring the significant environmental and social impacts of animal agriculture. (2) Images of farmed animals on packaging often do …

"I Dreamt Of Home": U.S. Veterans' Representations Of Wartime Experiences, Brenna Foley

Theses and Dissertations--Geography

This thesis employs several books from the Veterans Book Project, focusing on the stories of white male veterans of the Iraq War. I analyze these books through the lenses of banal nationalism, masculinity, feminist political geography and embodiment. Using archival and visual methods, I analyze how these books reproduce imperial logics and what this suggests about the veterans’ role in the everyday realities of war. Through analysis of these books, I examine the representation of the veterans’ wartime experiences and the reconstruction of veterans’ identities. This research seeks to understand how personal narratives reproduce imperial projects and colonialism through discourse …

The Impact Of Covid-19 On Collaboration And Turnover Among State Health Leadership, Kaylee Gouge

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Background/Objectives: State Health Officials (SHOs), the physician-leaders of state public health departments in the US, have long been indicated as potential peacemakers between the fields of medicine and public health. However, the average term length of SHOs has declined in recent years. Meanwhile, the COVID-19 pandemic has increased public visibility of state public health departments and their leadership. Some have hypothesized that the political strain of the pandemic has further accelerated SHO turnover, compromising their leadership efficacy. Contrarily, others have suggested that the pandemic would force public health and organized medicine into closer collaborative alignment through a common enemy. …

Attitudes Towards Fentanyl Test Strips Among A Cohort Of People Who Use Drugs In Rural Kentucky, Alaina Murphy

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Background and aims Fentanyl-related overdoses have largely contributed to the nearly 500,000 opioid overdose deaths in the United States since 1999. Fentanyl test strips (FTS) are a new technology that is designed to help prevent these overdoses. People who use drugs (PWUD) can test their drug supply for fentanyl by placing the strip in a sample of the drug. However, access to FTS varies across the country. This variance is largely due to rural PWUD not having the same access to harm reduction programs, compared to urban settings. This study uses data on PWUD in rural Kentucky to evaluate attitudes …

Local Public Health System Comprehensiveness And Opioid Overdose Mortality, 2012-2018, Stephanie Courtney

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Background: Deaths due to opioid overdose are a significant public health burden in the United States. Studies suggest that local public health systems that perform a high number of essential activities where local health departments contribute to the delivery of the activities and promote increased partnership may positively influence population health outcomes such as overdose mortality. Studies have shown that comprehensive public health systems are associated with improved health outcomes, but this association has not been addressed in the context of opioid overdose deaths. Study Aim: The purpose of this study is to evaluate the associations between local public health …

Neurophysiological And Psychological Characteristics Of Individuals With History Of Lateral Ankle Sprain, Katherine Bain

Theses and Dissertations--Rehabilitation Sciences

Lateral ankle sprain (LAS) is among the most common lower limb musculoskeletal injuries impacting both the general and sport populations. Even more problematic is that approximately 70% of individuals who sustain an LAS develop residual deficits. Of that subgroup, roughly 40% develop chronic ankle instability (CAI). Chronic ankle instability is a clinical diagnosis defined by the presence of ongoing impairments following the initial LAS which may include perceived instability, pain, mechanical instability, and episodes of giving way during physical activity. Not all who sustain multiple ankle sprains or experience residual deficits fit the clinical diagnosis criteria for CAI; yet may …

Content Validation Of A Patient-Reported Outcome Measure For Pediatric Clients With Hand And Upper Extremity Impairment, Jenny M. Dorich

Theses and Dissertations--Rehabilitation Sciences

Occupational therapists and physical therapists practicing in hand therapy have adopted routine use of patient reported outcome measures (PROMs) for evaluating treatment outcomes. However, the PROMs currently used in pediatric hand care are limited in clinical utility for the pediatric population. Thus, a need exists for developing a PROM that is tailored to the pediatric hand therapy population. The overarching purpose of this dissertation is to establish the content validity of a novel PROM for children with hand and upper extremity impairment – the Upper Extremity Life Impact Measure-Youth (UE LIM-Y).

This three-part dissertation applies published standards for PROM development …

The Experience Of Meditation, And Its Effects On Attention, For Adults With Stroke Or Attention Deficit Hyperactivity Disorder: A Three-Part Dissertation With Qualitative And Quantitative Evidence, Cheryl Carrico

Theses and Dissertations--Rehabilitation Sciences

Impairment of attention is common after stroke; is a defining characteristic of attention deficit hyperactivity disorder (ADHD); and has been shown to correlate significantly with difficulties in daily life for individuals with these conditions. More research is needed to establish effective interventions addressing impaired attention in such cases. Meditation is not a standard-of-care intervention for this purpose but may have therapeutic potential. Meditation has been broadly defined as an activity which has self-regulation of attention as its main aim. In other words, it can be considered a training of attention. To shed light on the therapeutic potential of meditation, including …

The Utilization Of Physical Literacy To Understand Physical Activity In Individuals With A History Of Anterior Cruciate Ligament Reconstruction, Rachel Renee Kleis

Theses and Dissertations--Rehabilitation Sciences

Injury to the anterior cruciate ligament (ACL) is common in physically active populations. Anterior cruciate ligament reconstruction (ACLR) is commonly performed after injury in order to restore joint stability and knee function and return patients to desired levels of physical activity. However, not everyone will return to their pre-injury levels of sport after surgery and recent evidence reveals that individuals with a history of ACLR are less likely to meet the recommended physical activity guidelines. Specifically, previous literature has reported that individuals with a history of ACLR take fewer daily steps and participate in less moderate-to-vigorous physical activity compared to …

Theses and Dissertations--Rehabilitation Sciences

The aim of this dissertation is to increase the body of research in occupational therapy about how to increase the social inclusion of children with disabilities in faith-based settings. Even since the advent of important legislation like the Americans with Disabilities Act, which paved the way for community participation for individuals with disabilities, individuals with disabilities continue to face barriers to participating in society. Decreased inclusion for individuals with disabilities is seen throughout all sectors of society. One area of regular societal participation for many Americans is in faith-based settings such as churches, synagogues and temples. It has been reported …

Telehealth Readiness In Older Adults In Kentucky, Kristen Weidner

Theses and Dissertations--Rehabilitation Sciences

During the COVID-19 pandemic, telehealth became an increasingly widespread service delivery model. Not all populations, however, accessed telehealth services equally. Older adults were less likely to use telehealth during the pandemic, continuing a historical trend. These usage patterns persist despite evidence that telehealth could be a helpful service delivery option for this population. Researchers have explored how theoretical frameworks explain older adults’ decisions to use technology, but there is yet to be a measure of older adults’ readiness for telehealth technology. A validated, theory-backed tool of older adults’ perceptions about telehealth, prior to the health care encounter, could help clinicians …

Theses and Dissertations--Rehabilitation Sciences

Across the United States, there has been a push to improve the literacy of our population, especially in the school systems. This has resulted in emphasizing reading skill development; however, literacy encompasses more than just reading. Literacy is the internal processes needed to create and understand contextualized visual, written, and verbal information. According to the Common Core State Standards, foundational literacy skills include reading, but also writing, listening, and speaking abilities. Handwriting is an area of literacy that is often forgotten, but has significant positive correlations to writing composition, spelling, and early reading skills. In fact, the Simple View of …

Implementation Of Physical Activity In Kentucky Public Schools: From Theory To Policy, Nancy Kearns

Theses and Dissertations--Rehabilitation Sciences

Physical activity in schools improves academic performance and fitness measures in children. However, state policy supporting implementation of physical activity remains poor. Identifying specific barriers to implementing physical activity minutes in Kentucky public schools is pivotal in preserving the cognitive and physical health of our children. This is of particular interest as physical activity minutes remain low despite the positive effects of exercise on cognition. The purpose of this dissertation is to provide policymakers and school administrators a method of identifying current policies, attitudes and infrastructure that inhibit the implementation of physical activity minutes in public schools. Thus, the findings, …
