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.

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 …

Rethinking Health Systems Responsiveness In Low–And Middle-Income Countries, Meesha Iqbal

Dissertations and Theses (Open Access)

Health systems responsiveness (HSR) refers to a health system’s ability to meet legitimate non-health expectations of the population. Traditionally, HSR has been conceptualized across eight domains: respect for dignity, autonomy, confidentiality, prompt attention to health needs, availability of basic amenities, choice of provider, access to social support networks, and clarity of communication. However, as the expectations of populations in high-income countries (HICs) and low- and middle-income countries (L&MICs) differ significantly due to diverse social and cultural contexts, the conceptualization of HSR also varies. We conducted a systematic review of literature to adapt and contextualize the HSR framework for L&MICs based …
