Envisioning Catholicism: Popular Practice Of A Traditional Faith In The Post-Wwii Us, Christy A. Bohl

Theses and Dissertations--History

Marian apparitions in the United States have occurred in ever-increasing numbers since World War Two, particularly in the 1980s and 1990s. These apparitions occupy a unique space in religious life, as they provide opportunities for Catholics to practice their faith outside of the Church hierarchy while still maintaining their status as faithful Catholics, often placing women in prominent positions. Although apparitions are an important part of faith for thousands of American Catholics, most Americans and Catholics are unaware of how widespread this movement is. This dissertation takes a comparative approach to examine a selection of apparition events, illuminating the pilgrimage …

Voices “Herd”: A Social And Sentiment Analysis Of Consumers Perceptions Of Fair Oaks Farms, Jacelyn De'nae Nesmith

Theses and Dissertations--Community & Leadership Development

Americans are searching for more information than just cost and quality of their food. Today, consumers are searching for information regarding the production practices and how animals are treated during the process. As consumers do not always have a first-hand source for this information, they are often referring to social media to have their questions answered. Social media has the reputation to negatively influence public perceptions of the agricultural industry. An example of an organization experiencing the consequences of social media influencing public opinion is Fair Oaks Farms. In 2019, an undercover animal rights activist group made accusations of poor …

An Examination Of Single-Sex Secondary Agricultural Education Classrooms: The Effects Of Teacher Expectancy, Brett Morris Wasden

Theses and Dissertations--Community & Leadership Development

The effectiveness of single-sex classrooms in the United States remains unclear. To address this issue, the purpose of this quasi-experiment was to examine single-sex classrooms in secondary agricultural education classrooms in Kentucky. Data were collected through quantitative pretests and posttests from student participants (n = 168) and teacher participants (n = 8). The findings indicated that student participants in single-sex classrooms had higher academic performance, better attendance, and an increased gain in interest in the agriculture, food, and natural resources career pathway. Students participants in coeducational classrooms had less discipline referrals. Teacher participants’ expectation were related to student …

Deselling: Cross-Selling Without Upsetting Customers, Molly R. Burchett

Theses and Dissertations--Marketing and Supply Chain

To boost revenue, many firms are encouraging their service salespeople to cross-sell while providing a service; but cross-selling can upset customers. How, then, may firms effectively cross-sell without upsetting customers? The authors address this question by introducing the concept of deselling behaviors, defined as service salespeople’s actions that are incongruent with persuasive intent. They combine insights gleaned from 101 inconspicuous, fly-on-the-wall videos of actual service salesperson-customer exchanges with theoretical underpinnings of the persuasion knowledge model and reactance theory to advance a novel conceptual framework of deselling behaviors. Their framework advances prior literature by illuminating three unique sets of deselling …

Why Weak States Balance: National Mobilization And The Security Strategies Of Post-Soviet States, Eteri Tsintsadze-Maass

Theses and Dissertations--Political Science

After the collapse of the Soviet Union, the 14 post-Soviet states adopted dramatically differing security strategies towards Russia: some sought security by bandwagoning with Russia while others strove to balance against it. Why did states with similar experiences under Soviet rule and similar asymmetric power positions vis-à-vis Russia adopt such diverse security strategies in the aftermath of the Soviet Union’s disintegration? In contrast to prevailing theories focusing on power, economic interdependence, and cultural similarities, I propose that these variations in post-Soviet states’ security strategies can be best explained by their diverse experiences with national mobilization. The central argument of this …

Nonparametric Analysis Of Clustered And Multivariate Data, Yue Cui

Theses and Dissertations--Statistics

In this dissertation, we investigate three distinct but interrelated problems for nonparametric analysis of clustered data and multivariate data in pre-post factorial design.

In the first project, we propose a nonparametric approach for one-sample clustered data in pre-post intervention design. In particular, we consider the situation where for some clusters all members are only observed at either pre or post intervention but not both. This type of clustered data is referred to us as partially complete clustered data. Unlike most of its parametric counterparts, we do not assume specific models for data distributions, intra-cluster dependence structure or variability, in effect …

Measuring Variability In Model Performance Measures, Matthew Rutledge

Theses and Dissertations--Statistics

As data become increasingly available, statisticians are confronted with both larger sample sizes and larger numbers of predictors. While both of these factors are beneficial in building better predictive models and allowing for better inference, models can become difficult to interpret and often include variables of little practical significance. This dissertation provides methods that assist model builders to better understand and select from a collection of candidate models. We study the asymptotic distribution of AIC and propose a graphical tool to assist practitioners in comparing and contrasting candidate models. Real-world examples show how this graphic might be used and a …

Olmstead Mandated Statewide Implementation Of Assertive Community Treatment: Precipitating Factors And Participant Experiences, Elizabeth Nelson-Cooke

Theses and Dissertations--Social Work

Evidence-based practices for individuals with serious mental illness have not been widely implemented in United States public mental health systems. Mental health advocates have used the Supreme Court’s Olmstead decision to force states with underfunded community mental health services to develop more robust treatment systems. Using a case study, this article-based dissertation examines the process of mandated widespread implementation of Assertive Community Treatment (ACT) in Kentucky through the experiences of individuals involved in ACT creation and documents related to implementation and the state mental health system. Study 1 identifies precipitating factors to the Kentucky Olmstead settlement agreement that contributed to …

Embodying Inequality: Three Papers On The Role Of Gender And Discrimination In The Lives Of Women, Stefana I. Moldovan

Theses and Dissertations--Social Work

Women experience different forms of discrimination throughout their lives such as unfair treatment in interpersonal interactions in the public spheres and in the private sphere, as prescribed by societal gender roles, women can also experience inequality and discrimination as a disproportionate share of household work and caregiving, limited participation in decision making, unequal access and share of financial resources and leisure, and as well as in cases, of emotional, and physical, or sexual abuse. Limited research explored the potential joint effect of these forms of discrimination. The questions explored in this dissertation were: (1) How does gendered intra-household inequality, experienced …

Characterization Of Rare Earth Elements In The Illinois Basin Coals, Alireza Valian

Theses and Dissertations--Mining Engineering

The purpose of this study is to characterize the distribution and occurrence of rare earth elements (REEs) in the coal and coal-related material from the Illinois Basin. For characterizing the distribution of REEs, 17 core samples were investigated from various parts in the basin. Also, several individual samples from coal preparation plants and isolated geological occurrences were included in the study. In result, the average REE concentrations were calculated on a bed-to-bed basis, although the distribution of REEs in the coal beds was found laterally and vertically heterogeneous. A number of trends were found that describe the variations. Most importantly, …

Development Of Universal Solver For High Enthalpy Flows Through Ablative Materials, Umran Duzel

Theses and Dissertations--Mechanical and Aerospace Engineering

Atmospheric entry occurs at very high speeds which produces high temperature around the vehicle. Entry vehicles are thus equipped with Thermal Protection Systems which are usually made of ablative materials. This dissertation presents a new solver that models the atmospheric entry environment and the thermal protection systems. In this approach, both the external flow and the porous heat shield are solved using the same computational domain. The new solver uses the Volume Averaged Navier-Stokes Equations adapted for hypersonic non-equilibrium flow, and is thus valid for both domains. The code is verified using analytical problems, set of benchmarks and also a …

Carbon Oxidation At The Atomic Level: A Computational Study On Oxidative Graphene Etching And Pitting Of Graphitic Carbon Surfaces, Simon Schmitt

Theses and Dissertations--Mechanical and Aerospace Engineering

In order to understand the oxidation of solid carbon materials by oxygen-containing gases, carbon oxidation has to be studied on the atomic level where the surface reactions occur. Graphene and graphite are etched by oxygen to form characteristic pits that are scattered across the material surface, and pitting in turn leads to microstructural changes that determine the macroscopic oxidation behavior. While this is a well-documented phenomenon, it is heretofore poorly understood due to the notorious difficulty of experiments and a lack of comprehensive computational studies. The main objective of the present work is the development of a computational framework from …

Expanded Predictive Equation For Dc Arc-Flash Incident Energy In 125v Battery Systems, Austin Gaunce

Theses and Dissertations--Electrical and Computer Engineering

Arc-flash is a dangerous phenomenon that can occur during an arcing fault in an electrical system. People nearby may be subjected to extreme heat, light, pressure, and sound. Research regarding arc-flash has focused primarily on AC arc-flash due to the prevalence of AC electricity in the grid. However, the grid has begun to integrate more DC electrical sources as a result of decentralization efforts and environmental concerns. The increased proliferation of DC electrical sources demands research into DC arc-flash to assess the hazard as low-voltage DC sources have already become commonplace. Some DC arc-flash models have been produced to estimate …

Impact Of Nicu Design On Feeding-Related Outcomes In Preterm Infants, Emma Kate Calvert

Theses and Dissertations--Communication Sciences and Disorders

Many NICUs around the country are moving away from traditional open-bay designs in favor of single-family rooms (SFRs) as more is understood about the impact of the sensory environment on neurodevelopment in preterm infants. SFRs house one infant and their family for the length of the infant’s stay and are associated with improvements in numerous outcomes, including increased milk intake and weight gain and earlier transition to enteral feeding. Oral feeding remains a critical requirement for NICU discharge; however, the impact of NICU design on feeding outcomes remains unknown.

The purpose of this study was to compare feeding outcomes between …

Legibility Of Communicative Writing And Drawing In Aphasia: Does The Orthographic Medium Matter?, Nicole Waugaman

Theses and Dissertations--Communication Sciences and Disorders

Expressive language difficulties are commonplace in aphasia and are often further complicated by co-occurring motor speech disoders. Therefore, many people with aphasia (PWA) are unable to meet all their communication needs by speaking, and they may compensate with the use of communicative writing and drawing. Communicative writing and drawing can be defined as preserved, but imperfect, orthographic skills that PWA use to compensate for expressive language deficits resulting from aphasic and/or motor speech difficulties. The purpose of this study was to determine if the orthographic medium used by a PWA to write and draw influenced the legibility of their writing …

An Evaluation Of Postural Control And Balance After Anterior Cruciate Ligament Reconstruction, Kathryn Lucas

Theses and Dissertations--Rehabilitation Sciences

Over 100,000 anterior cruciate ligament reconstructions (ACLR) occur annually in the United States, with one in four individuals sustaining a second injury within the first two years after reconstruction. Due to the proprioceptive nature of the anterior cruciate ligament, the lack of regaining postural control and balance are likely large contributors to the rate of secondary injuries after ACLR. Recent literature has identified cerebral changes after anterior cruciate ligament injury and surgery, likely due to altered sensation and feedback loops. However, no study thus far has investigated the neurological feedback loops that may place this group at higher risk of …

Transcriptomic And Cellular Response To Mechanical Overload And The Underlying Role Of Macrophages In Extracellular Matrix Remodeling, Bailey D. Peck

Theses and Dissertations--Rehabilitation Sciences

The extracellular matrix (ECM) in skeletal muscle plays an integral role in tissue development, structural support, and force transmission. Upon mechanical loading, including resistance exercise, which alter muscle fiber contractile activity, size, orientation and connectivity, remodeling processes must occur that involve both ECM deposition and degradation. ECM remodeling involves many cell types in muscle, but the focus of our research was directed towards macrophages, which participate in the early immune response to damage and loading. We have consistently demonstrated a significant increase in skeletal muscle macrophage abundance using pan macrophage markers (CD11b/CD68) and anti-inflammatory markers (CD206/CD163) following exercise training in …

Divergence In Neuronal Calcium Dysregulation In Brain Aging And Animal Models Of Ad, Adam Ghoweri

Theses and Dissertations--Pharmacology and Nutritional Sciences

Neuronal calcium dysregulation first garnered attention during the mid-1980’s as a key factor in brain aging, which led to the formulation of the Ca²⁺ hypothesis of brain aging and dementia. Indeed, many Ca²⁺-dependent cellular processes that change with age, including an increase in the afterhyperpolarization, a decrease in long-term potentiation, an increased susceptibility to long-term depression, and a reduction in short-term synaptic plasticity, have been identified. It was later determined that increased intracellular Ca²⁺ with age was due to increased Ca²⁺ channel density, elevated release from intracellular Ca²⁺ stores, and decreased Ca²⁺ buffering …

Remodeling In The Actin Core Of The Auditory Hair Cell Stereocilia As A Novel Component Of Temporary Noise-Induced Hearing Loss, Jonathan Michael Grossheim

Theses and Dissertations--Physiology

The rigid, paracrystalline actin core of auditory hair cell stereocilia is extremely stable and after initial formation must persist for the life of the cell to preserve hearing in mammals. In healthy hair cells, turnover of actin molecules occurs only in a small region near the tips of stereocilia, while the actin filaments of the shaft are stable. For decades damage to the actin core of stereocilia from acoustic trauma has only been attributed to cases of permanent noise-induced hearing loss. Here, we show that repairable actin core damage occurs in temporary noise-induced hearing loss from moderate acoustic trauma.

We …

Ceramide-Enriched Extracellular Vesicles: A Role In Enhancing Amyloid-Beta Neurotoxicity And Mitochondrial Damage In Alzheimer’S Disease, Ahmed Elsherbini

Theses and Dissertations--Physiology

Alzheimer’s disease (AD) is an age-dependent, progressive, neurodegenerative disorder that is characterized clinically by the impairment of cognitive functions concomitant with behavioral and personality changes. AD is associated with distinct pathological hallmarks, namely, intracellular neurofibrillary tangles comprised of hyperphosphorylated tau protein, extracellular amyloid beta (Aβ) plaques, and marked brain atrophy. Besides their main role as the core component of amyloid plaques, oligomeric Aβ have been shown to be neurotoxic. The exact mechanism of Aβ neurotoxicity is yet to be elucidated.

Recently, a pathogenic function of small extracellular vesicles- also known as exosomes- has been proposed, suggesting that exosomes can transfer …

Apparel Sizing And Fit For Girls: Variation Of Select Companies, And Parent Opinions, Peggy Sowah, Ashia

Theses and Dissertations--Retailing and Tourism Management

The act of shopping for girl's clothes is a delight of most parents. It ignites the pleasure of being a parent. However, many parents and their girls have experienced the frustration of inconsistent sizing and fit of their girl's clothes across brands. The purpose of this study was to understand the sizing and fit problems of girls ages 7-12 and to evaluate how brands utilize the current sizing standards. A structured questionnaire was used to collect data from a population of 150 (N=150) female parents. A survey was administered to help gain a better understanding and assess parent opinion of …

Pathogenicity, Toxigenic Potential, And Genomics Of Fusarium Graminearum And F. Meridionale Causing Ear And Stalk Rot Of Maize, Franklin Jackson Machado

Theses and Dissertations--Plant Pathology

Gibberella ear (GER) and stalk rot (GSR) diseases of maize in Brazil are caused mainly by Fusarium meridionale, a species belonging to the Fusarium graminearum species complex (FGSC). Another species within this complex, F. graminearum sensu stricto (hereafter F. graminearum), is second in importance on maize, but is the most common species found causing Fusarium Head Blight disease of wheat in Brazil. The latter species is the predominant cause of GER and GSR in North America, where F. meridionale has not been found thus far. In this dissertation I undertook a comparative analysis of pathogenic, saprophytic, toxigenic and …

Diet Of A Recently Reintroduced River Otter (Lontra Canadensis) Population In Taos County, New Mexico, Gabriela Alexandra Wolf-Gonzalez

Theses and Dissertations--Forestry and Natural Resources

North American river otters (Lontra canadensis), native to every U.S. state and Canada, experienced extensive population decreases and range reduction until the mid-20th century as a result of overexploitation and habitat loss during European colonization. The last known river otter in New Mexico was killed on the Gila River in 1953, although unverified reports continued thru 2008. After a nearly 60-year absence from New Mexico, 33 adult river otters were reintroduced to the Rio Pueblo de Taos in the northern part of the state between 2008-2010; however, they were not subsequently monitored or studied. I characterized diet of …

Food Abundance Modulates Juvenile Mussel (Unionidae) Growth Responses To The Asian Clam (Corbicula Fluminea), Drew Edward Jerry White

Theses and Dissertations--Forestry and Natural Resources

Interactions between the Asian Clam (Corbicula fluminea) and freshwater mussels (Unionidae) have been documented, but the effect of food abundance on these interactions is not well understood. I examined the role of food abundance in modulating the growth and survival responses of juvenile Cumberland Bean (Venustaconcha troostensis) to Corbicula. I ran a series of controlled experiments in which I tested the effect of Corbicula on growth and survival of juvenile freshwater mussels in multiple environmentally relevant conditions of food abundance. Corbicula had no effect on juvenile mussel survival, regardless of food abundance. However, juvenile mussel …

Long-Term Effects Of Crop-Tree Release On The Growth And Quality Of Upland White Oak Stands, Philip Jay Vogel

Theses and Dissertations--Forestry and Natural Resources

The alteration of historical disturbance regimes, forest parcelization, and varying goals among landowners all present challenges to oak management in the eastern U.S. Foresters and landowners need tools to promote oak sustainability that are applicable on small forestland holdings and within complex management plans. From this perspective, this research evaluates a crop-tree release study installed in southeastern Kentucky in 1983. The experiment includes four, 2-acre replications of three treatment levels: 20 crop-trees per acre, 34 crop-trees per acre, and a control treatment in which crop-trees were selected but not released. Half-acre measurement plots were installed at the outset of the …

Effects Of Shelterwood And Patch Cut Harvests On A Post White-Nose Syndrome Bat Community In The Cumberland Plateau In Eastern Kentucky, Phillip Lee Arant

Theses and Dissertations--Forestry and Natural Resources

The impact of shelterwood and patch cuts harvests on bat communities was tested at three sites in Eastern Kentucky. Shelterwood harvests had 50% of the basal area and understory removed to create a uniform spacing of residual trees. Patch cuts had 1-hectare circular openings created to remove 50% of the basal area creating an aggregated spacing of residual trees. Acoustic detectors were deployed to assess activity levels pre-harvest. Sites were then sampled from 1 – 2 years post-harvest to determine differences. Pre-harvest data revealed little acoustic activity for the Myotis spp. at two sites. The remaining site had high activity …

Enhancing Native Plant Diversity On Legacy Minelands, Anna Maria Branduzzi

Theses and Dissertations--Forestry and Natural Resources

Surface mining for coal has left scars on landscapes and reduced ecosystem functions across Appalachia for over a century. In the Monongahela National Forest, WV, a restoration project has been going on since 2009 on legacy minelands that dissect the biodiverse high elevation red spruce ecosystem. Goals of the restoration project include watershed improvement, soil building, enhancement of early successional habitat, and reforestation. Decompaction of the minelands is a critical step in the restoration process, and allows native vegetation to begin colonizing the site. Through this project, hundreds of vernal pools are constructed each year, and woody debris from non-native …

Aggregation Behavior In The Bed Bug, Cimex Lectularius L., Paul D. Baker

Theses and Dissertations--Entomology

The bed bug, Cimex lectularius L., is a common household pest that feeds on the blood of its human hosts. Unlike many other hematophagic arthropods, bed bugs have not demonstrated the ability to vector disease; yet its presence in a household often leads to fear and anxiety amongst its human host victims. Bed bugs spend the majority of their time aggregating in enclosed and hidden locations, making it difficult to detect and eradicate them. One of the significant mediators of aggregation behavior is an aggregation pheromone. The pheromone has been identified to be six chemical compounds, five volatile compounds that …

Management Of Sugarcane Aphid (Melanaphis Sacchari) Using Biological And Cultural Tactics In Kentucky, Nathan Harriman Mercer

Theses and Dissertations--Entomology

In 2013, a new aphid pest of sorghum, the sugarcane aphid Melanaphis sacchari Zehntner (Hemiptera: Aphididae), was found in the southern US, and caused significant yield loss in sorghum. Since then, M. sacchari has spread to most of the sorghum growing regions. Unmanaged populations can cause complete crop loss in grain, forage and sweet sorghum. M. sacchari cannot survive winters without a live plant tissue and must recolonize much of its pest range annually. Sweet sorghum (Sorghum bicolor) is an important crop for many growers in Kentucky, producing $16-25 million a year from its syrup. Biological control of …

Emotional Closeness Within Romantic Relationships: Is There Transmission Between Generations?, Mckenna Diane Fey

Theses and Dissertations--Family Sciences

This study tested the existence of intergenerational transmission of romantic emotional closeness using Galovan and Schramm’s (2018) model of relationship flourishing as a theoretical backbone. Romantic emotional closeness in the present study included intimacy (i.e., self-disclosure), admiration (i.e., appreciation expression), and dyadic coping. Couples among three generations from the Panel of Analysis of Intimate Relationships and Family Dynamics (Brüderl et al., 2013) were examined to test whether romantic emotional closeness in the first generation predicted romantic emotional closeness in the second generation, and whether that of the second generation predicted that of the third. Regressions within a partial latent model …
