Analyzing The Association Of Competitive Food Policy On Competitive Food Content In U.S. Schools., Mary E. Curnutte

Electronic Theses and Dissertations

OBJECTIVES: School food can have a profound effect on the population’s health. Thirty million children receive food at school and consume half their daily calorie intake at school. Competitive foods are foods sold outside of school breakfast and lunch, such as those sold in vending machines. A new ruling for Smart Snacks Standards, a set of competitive food guidelines, started in the school year 2014-2015. It is known that competitive foods undermine school lunch participation, and a decrease in school lunch consumption is associated with poorer student health. Additionally, an increase in competitive foods tends to be of nutrient-poor …

Predicting Confidence In Performing Mental Health Actions Among Allied Professionals., Jean Marie Zelenko

Electronic Theses and Dissertations

One in five young people before the age of 25 exhibit onset of symptoms of an emotional or behavioral disorder (Kessler et al., 2005). Up to 80% of depressed youth do not receive services (Kataoka, 2002) and less than 50% of the time youth seek help for suicidal ideation and/or self-harm (Michelmore & Hindley, 2012). This high prevalence of mental health distress and low frequency of help-seeking among youth require examination of factors influencing youths’ likelihood of seeking help. One factor that increases the likelihood of help-seeking is encouragement from others to seek mental health services (Cusack et al., 2004). …

A Black Sherlock Holmes: An Exploration Of Nonconforming Characterization., Faith Janaye Artis

Electronic Theses and Dissertations

In the wake of diversity initiatives in the greater American theatre landscape, we are now including more Black actors than ever. Whether that be through the inclusion of diverse playwrights or implementing new casting protocols, we now have Black people in the room. However, when portraying the Black “version” of a character (i.e. Black Annie, Black Ariel, Black Juliet) a question still plagues the Black Actor’s mind: how am I meant to fit here? I evaluate my process of portraying Sherlock Holmes as my thesis role. By challenging the implied white perspective in this “universal” story (despite its feminist retelling), …

Demon In The Dark: A Collection Of Short Stories., Giovanna Claudia Burkett

Electronic Theses and Dissertations

This creative thesis is a collection of short stories revolving around themes of grief, isolation, and survivor’s guilt. Each story is standalone even though they share overlapping motifs, as well as having a few references within the same universe. These protagonists often appear to be unreliable narrators, though the amount of reliability they depict should be determined by the reader. The protagonists encounter situations that cause them to question their own sanity and make them relive their greatest fears and confront traumatic memories, which may serve as a connection to the supernatural elements within the stories. Settings within each story …

Student Perceptions Of School Climate And Safety After The Collective Trauma Of Covid-19 And Racial Injustice Syndemic., Amy Catherine Lyons

Electronic Theses and Dissertations

For people in marginalized communities, particularly the Black and African American community, the combined, disproportionate damage and loss from of the pandemic and a cacophony of racial injustices offer cause for labeling the phenomenon a syndemic. Syndemic is defined as “a conceptual framework for understanding diseases or health conditions that arise in populations and that are exacerbated by the social, economic, environmental, and political milieu in which a population is immersed” (Singer et al., 2017, p. 881). The purpose of this study is to explore, describe, and analyze Kentucky students’ perceptions of school climate and safety by demographic groups, racial …

Cns-Specific Hiv Reservoir Characterization In Humans: Advancing Our Understanding Through Novel Genomics Methods., Ghazal Sadri

Electronic Theses and Dissertations

The persistence of the human immunodeficiency virus (HIV) reservoir despite years of suppressive antiretroviral therapy (ART) represents the principal obstacle to achieving a functional cure. Because the intact, replication-competent portion of the reservoir drives viral rebound after treatment interruption, HIV cure strategies must specifically identify and target cells harboring these proviruses. Conventional reservoir‐characterization techniques typically require separate assays to capture integration sites, assess proviral integrity, and quantify clonal proliferation and they rely on short‐read sequencing. These limitations hinder our ability to understand how integration landscapes, the integrity of the HIV genome, and cell‐division dynamics intersect to maintain viral persistence in …

Bayesian Model Updating Of Structural Parameters Using Temperature Variation Data., Ujjwal Adhikari

Electronic Theses and Dissertations

Physical digital twins have now emerged as a technology in structural health monitoring and other domains of structural modeling. A Finite Element Model can be a tool for digital twin technology in conjunction with measured physical data. Developing an accurate digital model requires the integration of various parameters to replicate the real structure; however, temperature is dynamically changing, resulting in difficulty in the identification of structural parameters. Typically, temperature is considered noise or filtered out. Limited research has addressed the physics-based model using temperature variation related to structural modal properties. Finite Element Model Updating (FEMU) is a typical inverse problem-solving …

Mechanisms Of Particulate Hexavalent Chromium-Induced Inhibition Of Homologous Recombination Repair: Targeting The Bcdx2 Complex Considered Through A One Health Perspective., Aggie W. Brownell

Electronic Theses and Dissertations

Lung cancer remains the leading cause of cancer death, often linked to smoking. However, smoking alone does not account for all cases. Exposure to environmental metals like hexavalent chromium [Cr(VI)] also contributes to lung cancer. Cr(VI) causes lung cancer by inducing chromosome instability (CIN), an early hallmark of its carcinogenic mechanism. While it has been established that Cr(VI) induces chromosome instability, the precise mechanisms underlying the chromosome instability are poorly understood. This dissertation investigates the mechanisms of carcinogenesis associated with zinc chromate, a particularly potent particulate form of hexavalent chromium. Studies show Cr(VI) induces DNA double-strand breaks and impairs the …

Sickle Cell Disease (SCD) is common in Saudi Arabia, with a prevalence rate of 2.3%. It is an expensive disease to manage due to the extensive utilization of healthcare resources, including hospital readmissions, extended hospital stays, and frequent emergency department visits, which cost approximately $395 million annually in U.S. dollars. The primary objective of this study was to conduct a systematic literature review of healthcare utilization and cost of patients with SCD, following the PICO framework and PRISMA guidelines. The second aim utilized count models, including the negative binomial and Poisson, to identify factors associated with emergency, inpatient, and outpatient …

Catholic High School Principals’ Experiences With Parent-School Relationships And Perceptions Of Self-Efficacy., Alexander J. Glaser

Electronic Theses and Dissertations

Principals feel overworked in part due to their responsibilities and the demands of the modern educational institution. Furthermore, dynamics between schools and parents are changing in an increasingly polarized climate. Catholic schools face a unique challenge as school choice is more prevalent and client pools become more diverse. Understanding self-efficacy is elemental to building resiliency in principals leading schools in the current climate. Through this mixed-methods phenomenological study, I sought to understand Catholic secondary school principals’ levels of self-efficacy in daily tasks and determine how parent-school relationships explain these perceptions. I used descriptive data and interviews which led to several …

A Sacrifice On The Altar Of Unity: The Loss Of Black Identity In The Unification Of Kynett And Lagrange First Umc., Rebecca Sue Wishnevski

Electronic Theses and Dissertations

This study examines the 1996 merger of Kynett United Methodist Church, a historically Black church, and LaGrange First United Methodist Church, a traditionally White church in LaGrange, Kentucky. The study provides insight into nonurban Black churches, showing that while they may have smaller congregations in smaller towns, the Black church remains central to Black life and connection like its urban contemporaries. Methods for collecting primary source material relied heavily on oral histories performed by the researcher with Black and White individuals attending said churches and their experiences during the merger. The study reveals that although unification promised a modern building …

Integration Of Multi-Omics Datasets Evaluating Structural And Functional Features Of The Gut Microbiome In People With Hiv (Pwh)., Aakarsha Vijayakumar Rao

Electronic Theses and Dissertations

Gut dysbiosis characterized by reduced abundance of beneficial butyrate-producing bacteria has been independently linked to HIV-1 infection and heavy alcohol drinking. Further, gut dysbiosis results in loss of gut barrier integrity, microbial translocation and host-specific systemic inflammation. Therefore, to evaluate the functional consequences of structural changes in the gut microbiome, integrated data analysis is imperative. In this dissertation, we perform integrated analyses using data from multi-omics platforms to examine the structural and functional features of the gut microbiome of PWH. Gut microbiome composition was evaluated by sequencing V4 region of 16S rDNA, concentrations of metabolites and host-specific immune markers were …

Temperament And Screen Time Into Adulthood, Kareem Barbis

Electronic Theses and Dissertations

The possible correlation between language skills, temperament, and screen time in adulthood is understudied. It was hypothesized that high effortful control scores and low childhood screentime would corelate with higher cognitive reflection scores and higher language skills. Using a correlational design, 162 participants were studied (M age = 19.17 years old, 80% female, 86% White, 6% Hispanic). Participants completed an adapted version of the Adult Temperament Questionnaire (Evans & Rothbart, 2007), Cognitive Reflection Test (CRT; Fredrick, 2005), the Cognitive Reflection Test 2 (CRT-2; Thompson & Oppenheimer, 2016), Thompson & Oppenheimer, 2016), a childhood screen time questionnaire, a bilingualism questionnaire, and …

Life History Inhibits Deleterious Effects Of Dams On Genetic Health And Structure Of A Headwater Stream Fish, Riley Phelps

Electronic Theses and Dissertations

Habitat loss, fragmentation, and land use changes in river networks are common globally. The resulting fragmentation of landscapes and riverscapes threatens biodiversity and can affect dispersal and subsequently, gene flow and genetic health of species. Headwater streams are an integral part of river networks and contribute to biodiversity by providing habitat for temporary and permanent residents, yet they are easily altered and fragmented. The sandhills chub (Semotilus lumbee) is an endemic headwater leuciscid that lives in highly fragmented streams of the sandhills ecoregion in North and South Carolina, USA. New knowledge on the population genetics of the sandhills chub is …

Additionally, body metrics, water chemistry, and weather and habitat conditions were evaluated on each sampling …

Investigating The Effect Of Fasting On Senescent Cells In Nothobranchius Furzeri Fish, Israel A. Akinola

Electronic Theses and Dissertations

Senescent cells (SCs) have been documented to accumulate with age in the organism. Recent studies have shown that reducing the number of SCs in an organism result in tissue rejuvenation and extension of life expectancy. Intermittent fasting is reported to have multiple health benefits and is speculated to reduce the burden of SCs. Nothobranchius furzeri are a new model organism for studying aging and for which there are short- and long-lived strains available. We hypothesize that long- and short-lived strains of N. furzeri will accumulate SCs at different rates; and that fasting will reduce the burden of SCs.

The results …

Investigating Exoneration Patterns Among Juveniles, Kristin Mahan

Electronic Theses and Dissertations

Exoneration from crime has been studied among adults, but exoneration of juveniles (i.e., persons under age 18) has not been analyzed as a separate entity, despite distinct legal systems and developmental considerations. Wrongful conviction, while not always indicative of innocence, devastates lives of convicted individuals and their families, while increasing public mistrust and sometimes failing to convict truly guilty individuals. This devastation, as well as vulnerability to wrongful conviction, is significantly increased for youth who miss out on crucial developmental years, milestones, and opportunities.

In the current study, I examined differing and intersecting contributors (i.e., individual characteristics, crime characteristics, legal …

An Assessment Of The Effects Of Indirect Consultation In Improving Quality Of Life For Adults With Intellectual And Developmental Disabilities, Sarah Michele Russell

Electronic Theses and Dissertations

Seventeen percent of the total population of children are living with an intellectual / developmental disability (IDD), and while resources and therapeutic interventions are accessible during early childhood years, they often cease after turning 21 years old. As a result, many adults with IDD do not acquire the skills necessary to live independently and sustain employment or meaningful relationships, impacting their independence and quality of life. The purpose of this study is to understand how self-management training (in the form of indirect consultation) for adults with IDD influence independence and socially significant behavior in relation to quality of life. The …

Heterotopias Of Confinement: Zoo Architecture And The Loss Of Elephant Agency, Clayton Gill Beasley

Electronic Theses and Dissertations

Zoos functions as a site where human-animal relationships are structured through built environments that mediate control and representation. This study examines zoos as heterotopias—spaces where power and surveillance are negotiated between human observers and captive nonhuman animals. While zoos are often framed as spaces of conservation and education, their architectural design reinforces hierarchies of observation and confinement, shaping both human perceptions of nature and the lived experiences of nonhuman animals. This research focuses on Asian elephants as a critical species within this framework, exploring how their captivity illuminates tensions between human-imposed structures and nonhuman autonomy. Drawing from theories of heterotopia, …

Translation Of The Carcinogenic Dna Breakage-Repair Inhibition Mechanism For Hexavalent Chromium To Its Key Targets: Lung Epithelial Cells, Lung Tissue And Impacts On The Genome., Idoia Meaza Isusi

Electronic Theses and Dissertations

Lung cancer is the leading cause of cancer death worldwide. Hexavalent chromium [Cr(VI)] is a human lung carcinogen with widespread occupational and environmental exposure. Despite the known health risks, how Cr(VI) causes lung cancer remains unclear. This dissertation investigates the mechanisms of Cr(VI)-induced carcinogenesis. Cr(VI) causes DNA damage, specifically DNA double strand breaks, and inhibits homologous recombination repair, a high-fidelity repair pathway. Unrepaired DNA double strand breaks or those repaired through error-prone pathways, progress to chromosomal damage, and chromosome instability. The latter is a common characteristic of Cr(VI)-exposed cells, and a hallmark of lung cancer. Although the mechanism of Cr(VI)-induced …
