Examining Parent Accommodation Of Anxiety And Irritability In Preschool-Aged Children., Anna Olczyk

Electronic Theses and Dissertations

Anxiety and irritability are common developmentally normative emotions in early childhood, yet are also related to risk for psychopathology in childhood, adolescence, and adulthood. Parenting behaviors, including parent accommodation, may influence this risk. Parent accommodation is the parent modification of child/family routines and/or avoidance of activities to reduce child distress and has been documented widely in the anxiety literature. Although some research has examined parent accommodation of anxiety in preschool-aged children, most research has investigated accommodation of anxiety in clinical samples of school-aged children. Further, despite high rates of co-occurrence between child anxiety and irritability, research on parent accommodation of …

Peer Functioning And Risk For Co-Occurring Adhd And Anxiety Symptoms In School-Aged Children: A Cross-Sectional And Longitudinal Analysis., Helena F. Alacha

Electronic Theses and Dissertations

Background. Youth with Attention-deficit/hyperactivity disorder (ADHD) often have higher rates of anxiety in comparison to their peers without ADHD. Children with co-occurring ADHD and anxiety exhibit a unique clinical presentation that poses challenges to both assessment and treatment. Consequently, children with comorbid ADHD and anxiety experience increased impairment, and often have poorer long-term outcomes than children with either ADHD or anxiety alone. Preliminary evidence suggests that different psychosocial phenomena commonly experienced by children with ADHD—such as peer functioning—may increase susceptibility to anxiety. Considering that children with ADHD encounter a range of peer difficulties, the present study proposed and evaluated different …

Assessing Medical Decision-Making Capacity: The Importance Of Patient Values., Emilee M. Ertle

Electronic Theses and Dissertations

A medical decision-making capacity (MDC) assessment is the assessment of an individual to determine whether they can make their own medical decisions or if a proxy decision maker must make care decisions on their behalf. These assessments are necessary when individuals experience cognitive impairments which limit their ability to think through complex medical decisions. Best practice for MDC assessments is a growing area of research, with no standard approach to guide assessment planning. The current study builds upon the field’s knowledge of capacity assessments by investigating 1) what methods and measures clinicians utilize in capacity assessments, 2) what factors influence …

Dementia Caregiving Styles: Characterizing Dementia Caregivers Via A Novel Framework., Darby M. Simon

Electronic Theses and Dissertations

As dementia rates increase, effective family caregivers are crucial to meeting the increasing demand for dementia care. However, dementia caregiving is a demanding experience, and caregivers have varying strategies for providing care, leading to positive and negative outcomes and appraisals of their caregiving experience. Limited research explores this relationship, and extant work is qualitative with no clinical measure. This study adapted a pre-existing framework/measure from a different caregiver population (parents) to explore a) if the same framework applied to both caregiving populations and b) the associations between the styles and psychological well-being and other caregiving variables. Exploratory Factor Analysis tested …

Cbl Regulation Of C-Met Signaling In Corneal Epithelial Cells., Kate Elise Tarvestad Laise

Electronic Theses and Dissertations

The cornea is the most anterior portion of the eye and permits light passage through to retina, allowing formation of a clear image as long as it remains healthy. If the cornea sustains damage, it creates and entrance for foreign body invasion, infection, and ultimately blindness in the immunocompromised eye. Healing the corneal tissue is critical for vision restoration and pain alleviation, as it is the most densely innervated tissue in the body. Growth factors and their cognate receptors are currently under investigation as tools to restore proper corneal physiology. We hypothesize that manipulating the hepatocyte growth factor (HGF) /c-Met …

Metabolic Regulation Of Cardiac Fibroblast Phenotype And Function., Collin Kleis Wells

Electronic Theses and Dissertations

Cardiac fibroblasts are central effectors of cardiac repair after myocardial infarction (MI). In response to signaling cues, they differentiate to a range of phenotypes with robust capacities to synthesize and secrete extracellular matrix (ECM) and signaling molecules. Although activated fibroblast phenotypes are associated with pronounced changes in metabolism, it remains unclear how the metabolic network upholds the effector functions of fibroblasts in the post-infarcted heart. Here, we identified that critical enzymes in the phosphoenolpyruvate (PEP) cycle, i.e. pyruvate kinase muscle-2 (PKM2) and phosphoenolpyruvate carboxykinase-2 (PCK2), are elevated in the heart after MI and examined their role in regulating post-MI remodeling …

Hybrid Geographies And Nature In The City: A Tale Of Two Greenspaces In Louisville, Ky., Rebecca Dixon

Electronic Theses and Dissertations

Many conservation initiatives position nature and the urban as opposing constructions, which means the possibilities where cities can work with nature are often overlooked. This study uses the lens of relational geographies to examine nature in the city by comparing two greenspaces in the Beargrass Creek watershed in Louisville, Kentucky: Waterfront Botanical Gardens and the Louisville Nature Center. The two organizations are compared by using a combination of content analysis, discourse analysis, and GIS flood analysis methods to determine how their geographical location and history affect the ways in which the dynamic between nature and culture is reproduced.

Estimation Methods For Bayesian Exponential Random Graph Models Under The Horseshoe Prior., Pamela Linares

Electronic Theses and Dissertations

Networks are powerful tools for modeling the complexity of social interactions, biological systems, and information spread. A leading statistical frameworks for analyzing network data are Exponential Random Graph Models (ERGMs), which provide a principled approach to capturing structural dependencies. However, ERGMs remain challenging to estimate, especially in sparse or high-dimensional settings where models suffer from degeneracy and unstable parameter inference. This paper proposes a penalized Bayesian approach to ERGMs that utilizes the horseshoe prior, a sparsity-inducing global-local shrinkage prior. This prior offers robust regularization while preserving important signals, improving estimation by shrinking irrelevant parameters and reducing the impact of extreme …

Opportunities For Mathematical Thinking (Omt) In Fourth Grade Mathematics Textbooks., Lucas Wayne Elliott

Electronic Theses and Dissertations

Mathematical thinking is essential not only for students’ academic achievement but also for their ability to compete in a global workforce (Schoenfeld, 1992; Mullis & Martin, 2017). However, students in the United States continue to lag behind their international peers on assessments that measure mathematical thinking (Mullis et al., 2020; van Davier et al., 2024). These gaps emerge as early as elementary school, where the foundation for future academic success is established (Aunola et al., 2004; Locuniak & Jordan, 2008). Given the importance of mathematical thinking and the persistent disparities in student performance, this study examined how mathematical thinking is …

Immunopathogenic Crosstalk Between Cancer And The Kidney: A Central Role For Macrophages As Potential Mediators., Dana Hammouri

Electronic Theses and Dissertations

Cisplatin remains a mainstay in the treatment of solid tumors, yet its therapeutic efficacy is frequently compromised by dose-limiting nephrotoxicity. Approximately 30% of patients receiving cisplatin develop acute kidney injury (AKI), which increases the risk of chronic kidney disease (CKD), a leading cause of morbidity and mortality. Despite extensive preclinical efforts, no FDA-approved therapy currently exists to prevent or treat cisplatin-induced nephrotoxicity (CIN). This in part is due to the reliance of preclinical studies on non-cancer animal models that fail to capture the complex physiological alterations associated with malignancy. To address this limitation, we developed a clinically relevant model in …

Rhetorical Analysis Of Kristen Bell's Articulation Of Imperfect Motherhood On Armchair Expert., Sarah J. Neff

Electronic Theses and Dissertations

This thesis explores how Kristen Bell’s articulation of imperfect motherhood, as heard on the popular podcast Armchair Expert, contributes to broader social discourses surrounding motherhood, empowering some mothers while inadvertently constraining others. Using rhetorical analysis grounded in Goffman’s dramaturgical approach, facework theory, and McGee’s theory of fragments, this study explores Bell’s discourse and performance of motherhood within the podcast medium. The podcasting medium provides a rich source for rhetorical analysis due to the long form interview content, and emotionally nuanced content, leading to a stronger connection with the audience. This is evident with the new headlines that follow Bell’s appearance …

Role Of Cardiac Ketone Body Metabolism In Myocardial Perfusion And Exercise Performance., Kara R. Gouwens

Electronic Theses and Dissertations

Cardiorespiratory fitness, a crucial determinant of overall health and a strong predictor of all-cause mortality, is largely dependent on the capacity of the cardiovascular system to deliver oxygen and nutrients. The heart, as the central pump, requires a continuous and adaptable oxygen supply, particularly during increased workload such as occurs with exercise. Impaired myocardial blood flow (MBF) in response to increased demand can lead to ischemia, limiting exercise capacity and potentially causing severe cardiac events. Interestingly, changes in myocardial metabolism and cardiac work correlate with changes in MBF. Therefore, understanding the regulation of MBF, especially the link between local cardiac …

The Substance Of Reality: Moral Perfectionism In Shakespeare's Hamlet., David Wright

Electronic Theses and Dissertations

Through a selection of and close reading of key passages, I offer an interpretation of Hamlet that seeks to illuminate the play as an important work of moral philosophy, and to situate the play within a strand of moral philosophy named moral perfectionism by Stanley Cavell. Indeed, Hamlet is a masterpiece of Renaissance drama, but when read with attention to moral perfectionism, the play yields additional layers of meaning. Hamlet is a “philosophical drama” that navigates the “moral calling of philosophy”—a text that seems to, almost uncannily, elicit the audience to think reflectively, to ask fundamental human questions along …

Mindfulness As A Protective Factor In Women’S Sexual Health, Shana Byerley

Electronic Theses and Dissertations

Many women who experience physical health complaints also report sexual dysfunction across a variety of domains including decreased arousal, desire and satisfaction. Although there are well-established connections between disease-specific populations and sexual dysfunction, less research has focused on women who experience somatic symptoms more broadly. Similarly, mindfulness as a treatment intervention has been applied across many facets of sexual functioning, but mindfulness as a trait characteristic has been less explored in its connections with generalized somatic complaints. Further, the within-domain interactions between facets of mindfulness and domains of sexual dysfunction have not been previously explored. Using data from an online …

Reentry For Formerly Incarcerated Individuals: A Focus On Workforce Reentry And Recidivism In Appalachia, Margaret E. Francisco

Electronic Theses and Dissertations

Formerly incarcerated individuals face challenges to successful reentry, a critical component of reducing recidivism and improving public health outcomes. These challenges are particularly acute in rural Appalachia, where structural disadvantages such as limited economic opportunities, healthcare access, and public transportation intersect with stigma and systemic barriers related to prior incarceration. This dissertation addresses these gaps through a mixed-methods examination of reentry and recidivism, grounded in public health frameworks and focused on the unique context of rural Appalachia.

Hierarchy In Sensation: Exploring The 40 Hz Auditory Steady State Synchrony In The Primary Auditory And Prefrontal Association Cortices, Deepshila Gautam

Electronic Theses and Dissertations

Auditory processing begins in the cochlea and ascends through brainstem relays to the cortex, where sound features with increasing complexity are encoded. The 40 Hz auditory steady-state response (ASSR) reflects induced gamma synchrony shaped by local cortical circuit dynamics. Disrupted 40 Hz ASSR is a consistent finding in schizophrenia, linked to N-methyl-D-aspartate receptor (NMDAR) hypofunction in inhibitory interneurons, making it a promising translational biomarker. While multiple ASSR generators have been identified, it is not known if these are redundant or represent unique activity. This dissertation investigates regional differences in 40 Hz ASSR across two principal generators: the primary auditory cortex …

Comparison Of Nutrient Concentrations And Primary Production Indicators Across Plume Fronts, Taylor Dishon

Electronic Theses and Dissertations

Coastal buoyant plumes carry low-salinity waters containing particulate and dissolved terrestrial materials with an abundance of nutrients into the coastal ocean, including inorganic nitrogen and phosphorous. Plume fronts act as transport barriers created from the convergence of a fresher plume with an older, saltier plume or with ambient waters, leading to potential accumulation of phytoplankton and nutrients. This accumulation creates an optimal environment for primary production. The primary goals of this study were: to investigate the distribution of and potential relationships between nutrient concentrations and chlorophyll a across plume fronts of the Winyah Bay River Plume, and examine potential relationships …
