“I Hear You”: Exploring The Lived Experience Of Counselors’ Empathic Response To Clients When Conducting Telephonic Counseling During Covid-19, Michael Sickels

Electronic Theses and Dissertations

Dissertation supervised by Dr. Debra Hyatt-Burkhart

This study sought to unearth the lived experience of counselors empathically responding to clients via telephonic counseling during COVID-19. The term empathic response refers to as attending to the emotional and mental state of another person in a way that is attuned with the feelings and meanings of the individual’s experience. There are few studies that have assessed the merits of telephonic counseling, and even fewer that have examined counselors’ empathic response to clients through this medium.

To uncover the lived experience of the target population, the participants of the study were purposefully selected …

Rendering Documentary Portraiture: An Interrogation Of Archival Discourse Through A Critical Exploration Of Nineteenth Century Stage Actress Charlotte Cushman’S Material Memory, Skyler Sunday

Electronic Theses and Dissertations

Visual depictions of nineteenth century stage actress Charlotte Cushman, such as photographs, engravings, and painted portraits assist researchers in re-envisioning her both as an actress and as a person, but what do her remaining archival possessions further reveal to researchers about her memory? How do different objects operate as portraits that allow the researcher to tap into and remember specific moments and memory? How does the effort to preserve memory take different forms? This project argues that, when viewing the archive through its stored objects, our collective notion of portraiture can be expanded and used to interrogate existing methods of …

Labeling Melanoma Cells With Black Microspheres For Improved Sensitivity In Detection Via Photoacoustic Flow Cytometry, Tori Kocsis

Electronic Theses and Dissertations

Melanoma is an aggressive form of skin cancer known for developing into metastatic disease. Current clinical diagnostics, including medical imaging and tissue biopsy, provide a poor prognosis since the cancer is in the late stages of disease progression. In recent years, photoacoustic flow cytometry has allowed for the detection of circulating melanoma cells within patient blood samples in vitro. Although this method exploits the naturally-produced melanin within the cells, it has only successfully detected highly-pigmented melanoma cell lines. Since various forms of melanoma exist, each with varying melanin concentrations, this research aims to provide a novel method for detecting lightly-pigmented …

Soil Salinity And Sodicity Of Galveston And Pelican Islands, Texas, Rachel Murray

Electronic Theses and Dissertations

Galveston Island, Texas, is frequently affected by hurricanes. In 2008, Hurricane Ike inundated much of the island with seawater, causing elevated soil salinity levels that killed much of the vegetation on the island, including tens of thousands of trees. Residual salinity in soils and groundwater has hampered vegetation re-establishment in some areas.

This project aims to create a map product that displays the current soil salinity and sodicity levels on Galveston and Pelican Islands. The existing USDA Natural Resource Conservation Service (NRCS) Galveston County Soil Survey map units were used as a base for the project. ArcGIS Desktop software was …

Translating Particulate Hexavalent Chromium-Induced Chromosome Instability From Human Lung Cells To Experimental Animals, Human Lung Tumors And Whale Cells., Haiyan Lu

Electronic Theses and Dissertations

Lung cancer is a major human health problem. While smoking is the most well-known cause of lung cancer, people who never smoked develop the disease. Understanding how non-tobacco environmental carcinogens cause lung cancer is key to combating this disease. Hexavalent chromium [Cr(VI)] is a well-established human lung carcinogen, but its carcinogenic mechanism is uncertain. Chromosome instability (CIN) is a hallmark of lung cancer and a major factor in Cr(VI)-induced lung cancer. Studies in human lung cells show Cr(VI) induces DNA double strand breaks and suppresses homologous recombination (HR) repair by targeting RAD51, resulting in CIN. We translated these outcomes to …

Voices Of The "Served": Community Resident Perspectives On International Service-Learning In Peru., Adam C. Stieglitz

Electronic Theses and Dissertations

The purpose of this study is to capture and share community resident perspectives on international service-learning (ISL). Community resident voice is largely underrepresented in ISL scholarship and practice. Conversely, research on student outcomes is ubiquitous, which generally makes student benefit a predominant consideration in ISL program design. Consequently, scholars have criticized ISL programs for being inherently extractive and even an embodiment of modern-day colonialism. This study aims to address this critique by offering a robust representation of community residents’ perspectives for how to responsibly design ISL programs. This study used action research methodology to capture community resident voices who participate …

The Effects Of Gang Membership And Transitions In A Gang On Within-Individual Changes In Offending., Leon Sergio Garduno

Electronic Theses and Dissertations

Researchers have established that joining a gang exposes individuals to factors and environments that promote and increase antisocial and illegal behaviors, which decrease after leaving the gang (Decker & Van Winkle, 1994; Melde & Esbensen, 2014; Thornberry, Krohn et al., 1993). Scholars, by analyzing qualitative data, bivariate statistics, and by comparing gang members with non-gang members, have found that as individuals join and leave a gang they experience changes in the frequency with which they carry firearms, sell drugs, and engage in property crimes (Bjerregaard & Lizotte, 1995; Hagedorn, 1994; Thornberry et al., 1993). Researchers also have established that within-individuals’ …

Targeting Pathological Changes In The Gut Protects The Cns From Neuropathology., Benjamin Tyler Charpentier

Electronic Theses and Dissertations

There is growing evidence that the health of the gut microbiome (GM) has an important role on multiple host organ systems. Ethanol-related neuropathologies and Alzheimer’s disease (AD) currently have no effective clinical treatment. Therefore, we developed a novel mouse model of fecal matter transplantation (FMT) utilizing the microbiome from alcoholic hepatitis (AH) patients, characterized by a loss of butyrogenic potential. Minimal neuroinflammation occurred in AH-FMT mice, but significant increases in the endoplasmic reticulum stress response (ERSR) across the majority of neurons in the prefrontal cortex and hippocampus were observed. In the cerebellum, Purkinje cells were specifically affected. Targeting the loss …

Classifying The 2022 Status Of Tsuga Canadensis (Eastern Hemlock) Along The Kentucky Portion Of The Pine Mountain Wildlands Corridor., Grace M. Embree

Electronic Theses and Dissertations

The invasion of the Hemlock Woolly Adelgid (HWA) (Adelges tsugae) has posed a continual threat in the United States to the Eastern Hemlock (Tsuga canadensis) trees since the 1950s. HWA feed on eastern hemlock needles, reducing the amount of healthy photosynthesizing vegetative area. The use of satellite imagery has been instrumental in identifying areas of eastern hemlock presence. Satellite platforms like Landsat and AVIRIS are commonly used for identification, classification, and mapping of eastern hemlock. Sentinel-2 imagery was released in 2015 for free access. It has a finer spatial grain of with the majority of the …

Meeting The Mental Health Needs Of College-Aged Young Adults: Evaluating The Value And Impact Of Digital Mental Health Interventions., Sara Atherton Choate

Electronic Theses and Dissertations

BACKGROUND: The growing prevalence of common mental health problems poses a serious hindrance to young adults, and the majority of those in need of mental health support do not seek professional psychological services. Digital mental health interventions (DMHIs) that allow for self-management of mental health symptoms could provide a useful adjunctiveto traditional one-on-one counseling or therapy and offer a useful prevention tool for students at risk for experiencing mental health crises. This dissertation explored the efficacy of self-guided DMHIs targeting college students, the factors associated with help-seeking in young adults, and the impact of implementing an evidence-based DMHI at a …

The A-Word: Destigmatizing Abortion In American Culture., Kathryn Lafferty Danner

Electronic Theses and Dissertations

This dissertation uses an interdisciplinary perspective and explores the topic of abortion through legal, medical, philosophical, and cultural perspectives, providing alternative ways to talk about abortion. In some states, especially since the overturning of Roe, abortion has become almost impossible to access, particularly in the South and Midwest. Abortion as a medical procedure is highly stigmatized and although it is a common procedure, it is taboo to discuss in American culture. Exploring how different media work to destigmatize abortion in the United States can lead to a deeper, more nuanced understanding of an overly politicized topic. The introduction is a …

Disparate Sense Of Exclusion Between Young People Of Color Living Within Variable Social Infrastructures., James M. Joyce

Electronic Theses and Dissertations

I analyzed transcripts of listening sessions with youth/young adults of color in 2021-2022 for the purpose of addressing local racial inequity during COVID-19. I used inductive coding methods and found three themes on sense of exclusion to be most salient. These themes related to racial exclusion, exclusion of social infrastructures in the community, exclusion of young people of color by people working in schools and other public settings, and exclusion or disconnection of young people of color from opportunities for building community. I show how these themes vary across some dimensions of the local social infrastructure, and I discuss implications …

“…You Can't Unknow It, It's A New Reality": A Case Study Exploring A Social Justice Public Health Intervention's Impact On Critical Consciousness Development In Youth., Monique Williams

Electronic Theses and Dissertations

Even though public health purports to be rooted in social justice, it is not clear how social justice frameworks are integrated in public health research and intervention. The discipline focuses on groups/populations on the margins, without integrating the social and political factors that cause marginalization into the intervention. Seeing communities, and individuals, as assets and experts in their own experiences is key to population-level health improvement. Particularly for public health youth intervention, how youth are labeled and engaged in social change is critical to their healthy development. While public health lags in practically applying asset-based approaches to youth intervention, research …

The Influence Of Sponsorship Engagement On Brand Loyalty: An Analysis Of The On-Site And Social Media Activational Communications., Achyut Kulkarni

Electronic Theses and Dissertations

The purpose of this study was to investigate the influence of sponsorship engagement (enacted via sponsorship activations) on consumers’ responses to sponsors’ activational communications. Specifically, this study aimed at examining if interaction and engagement with their team’s sponsors’ activational communication on-site, as well as on social media, influenced loyalty towards the sponsors. The study utilized service-dominant (S-D) logic as the theoretical framework. The S-D logic perspective recognizes that consumer behavior is centered on the interactive experiences between a consumer and an object, in this case the sponsor, and that a level of consumer interest and/or personal relevance with respect to …

"I Am Who I Am": Lgbtq+ Student Experiences At A Baptist Liberal Arts University., Edwin Pavy

Electronic Theses and Dissertations

Though studies exploring the experiences of LGBTQ+ students on Christian college and university (CCU) campuses are increasingly prevalent, research continues to demonstrate that CCU environments are often unwelcoming. Gender and sexual minority students often face additional challenges or risks in attending a faith-based institution. To drive meaningful change, recommendations need to be tailored to individual institutions. This study sought to make meaning alongside LGBTQ+ students at a single institution – Baptist Heritage University (BHU) – with a decidedly appreciative approach. Grounded in Bronfenbrenner’s ecology of human development, we conducted an arts- based action research study to gain a deeper understanding …

As organizational connectors, athletic administrators who serve as sport supervisors, are integral to the success of intercollegiate athletic departments. However, little is known about the role of sport supervisor or the relationship between sport supervisors and head coaches. Thus, this study seeks to define and better understand the role of the sport supervisor in intercollegiate athletics and explore the relationship between the sport supervisor and the head coach. Through a descriptive phenomenological approach, 22 participants (11 sport supervisors and 11 head coaches) from NCAA Division I institutions were interviewed. Role theory guided the defining of the role while leader-member exchange …

Induction Of Trained Immunity By Particulate Β-Glucan Controls Cancer Metastasis Through The Sphingolipids-Mediated Mitochondrial Fission Pathway., Rejeena Shrestha

Electronic Theses and Dissertations

Metastasis is the leading cause of cancer-related deaths and innate immune cells are critical players in the metastatic microenvironment. Here, we explore the implications of harnessing the pre-metastatic niche myeloid cells through induction of trained immunity using a natural compound yeast-derived whole β-glucan particle (WGP). WGP training in macrophages results in an increased responsiveness to not only the conventional secondary stimulus LPS but also specifically to tumor cells and tumor-derived factors. WGP in vivo treatment leads to a trained immunity phenotype in lung interstitial macrophages (IMs). Induction of trained immunity by WGP inhibits tumor metastasis and enhances tumor-free survival in …

Investigating The Shared And Unique Mechanisms Of The Development Of Comorbid Eating Disorder-Anxiety Symptoms During Adolescence., Leigh Cara Brosof

Electronic Theses and Dissertations

Introduction: Eating disorders are associated with significant morbidity, psychiatric comorbidity, and impairment. Despite the detrimental outcomes associated with eating disorders, effective treatments for eating disorders are lacking. One factor that has impeded the identification of targets for intervention in eating disorders is the high comorbidity rate with other psychiatric disorders. Comorbidity models can inform treatments by showing which mechanisms are shared in comorbidity and which mechanisms are unique to specific disorders. Anxiety disorders are the most frequently co-occurring disorders with eating disorders, as 85% of individuals with eating disorders have a comorbid anxiety disorder. One mechanistic process in both anxiety …

Pediatric Oncology Social Work Job Analysis., Alyssa Ashlyn Middleton

Electronic Theses and Dissertations

This dissertation is an examination of the tasks most important to the pediatric oncology social work role. It begins with an argument that pediatric oncology social work is a blend of four social work specialties: generalist medical social work, oncology social work, pediatric social work, and hospice and palliative care social work. Studies report pediatric oncology social workers feel unprepared for numerous tasks related to their role. Despite calls for increased education and training opportunities, few are available. Until now, there has been no study evaluating the tasks that pediatric oncology social workers deem most important to their role, nor …

Media Portrayal Of Private Prisons And Inmates., Ladye Anna L. Adams

Electronic Theses and Dissertations

Private prisons have existed in the United States since 1986, but research about prison privatization has been limited. To date, there have been two published studies examining how mainstream media sources frame prison privatization to their audiences. This thesis attempts to address this gap in the literature. Using content analysis, I evaluate how mainstream media frames prison privatization and inmates housed in private prisons. The analysis is conducted in two parts. The first tests if private prison reduction or expansion is the focus of the news story if framed using economic benefits, ethical concerns, or prisoner violence. The second tests …

Statistical Methods For Personalized Treatment Selection And Survival Data Analysis Based On Observational Data With High-Dimensional Covariates., Don Ramesh Dinendra Sudaraka Tholkage

Electronic Theses and Dissertations

Due to the wide availability of functional data from multiple disciplines, the studies of functional data analysis have become popular in the recent literature. However, the related development in censored survival data has been relatively sparse. In Chapter 2, we consider the problem of analyzing time-to-event data in the presence of functional predictors. We develop a conditional generalized Kaplan Meier (KM) estimator that incorporates functional predictors using kernel weights and rigorously establishes its asymptotic properties. In addition, we propose to select the optimal bandwidth based on a time-dependent Brier score. We then carry out extensive numerical studies to examine the …

Limitations include exposure measurement error and lack of investigation of effect modification by important factors. This dissertation aims to expand on the current understanding of these relationships by limiting exposure measurement error and by assessing effect modification. Methods: We estimated the distribution of total environmental noise in Louisville, Kentucky for several time-periods using land use regression (LUR) methodologies. Additionally, through multiple regression models, we estimated the association of environmental noise during relevant time-periods with childhood …

Molecular Mechanisms Of Hexavalent Chromium-Induced Centrosome Amplification., Jennifer Haruka Toyoda

Electronic Theses and Dissertations

Lung cancer is the deadliest form of cancer and resulted in 1.8 million deaths worldwide in 2020. While cigarette smoking is the most familiar cause of lung cancer, up to 25% of cases occur in non-smokers, thus other environmental agents are also causative. Hexavalent chromium [Cr(VI)] is a known lung carcinogen and poses occupational and environmental exposure risks relevant to humans, wildlife, and ecosystems. This dissertation considers the carcinogenic mechanisms of a highly potent, particulate, hexavalent chromium compound, zinc chromate. The molecular mechanism of carcinogenesis induced by Cr(VI) is not fully understood, but it is known that chromosome instability is …

Application Of Cannabidol To Ocular Pharmacokinetics And Pharmacodynamics., Alyssa Laun

Electronic Theses and Dissertations

Cannabidiol (CBD) is the most abundant non-psychotropic cannabinoid constituent of Cannabis sativa. CBD is potentially therapeutic for the eye through antioxidant, anti-inflammatory, and neuroprotective effects. However, the effect of CBD on intraocular pressure (IOP)- the major risk factor for glaucoma- is controversial and large variability exists in the literature. IOP is regulated through aqueous humor (AH) dynamics in trabecular meshwork (TM) tissues. Measurement of CBD in AH and correlation with effects on IOP would clarify what concentrations mediate changes to IOP. Therefore, the overall goal of this dissertation is to measure CBD in ocular tissues and correlate concentrations with …

Ecological Differences In The Associations Between Air Pollution, Greenness, And Risk Of Stroke: The Regards Study., Daniel W. Riggs

Electronic Theses and Dissertations

The adverse health effects of air pollution have long been recognized, with the majority of morbidity and mortality due to its effects on the cardiovascular system. Alternatively, living in areas with higher greenness has been found to be beneficial to a wide range of health outcomes. However, few studies have considered that these relationships may vary depending on the surrounding ecosystem. The purpose of this dissertation was to examine the effects of long-term exposure to air pollution and greenness on incidence of stroke, and how these relationships vary with the major ecological regions of the United States. We utilized the …

Role Of Machine Learning In Early Diagnosis Of Kidney Diseases., Mohamed Nazih Mohamed Ibrahim Shehata

Electronic Theses and Dissertations

Machine learning (ML) and deep learning (DL) approaches have been used as indispensable tools in modern artificial intelligence-based computer-aided diagnostic (AIbased CAD) systems that can provide non-invasive, early, and accurate diagnosis of a given medical condition. These AI-based CAD systems have proven themselves to be reproducible and have the generalization ability to diagnose new unseen cases with several diseases and medical conditions in different organs (e.g., kidneys, prostate, brain, liver, lung, breast, and bladder). In this dissertation, we will focus on the role of such AI-based CAD systems in early diagnosis of two kidney diseases, namely: acute rejection (AR) post …
