Partitions Into Sums Of Two Squares And Gaps Between Zeros Of L-Functions, Jaime Hernandez Palacios

Electronic Theses and Dissertations

This work consists of two distinct problems. In the first one, we use a variation of the Circle Method, along with ideas coming from the Saddle Point Method, to obtain an asymptotic formula for the number of partitions of a number n into integers which are sums of two squares. In the second problem, we discuss some new results for large and small gaps between the ordinates of zeros of high degree zeta and L-functions, including Dedekind zeta-functions associated with Galois extensions of Q and principal automorphic L-functions.

From Difficult Heritage To A Symbol Of Peace: A Case Study Of The Chibondo Mass Grave In Zimbabwe., Peter Mudzingwa

Electronic Theses and Dissertations

This thesis examines the contested interpretation and memorialization of the Chibondo mass grave in Zimbabwe, analyzing how unresolved historical grievances shape national reconciliation efforts. Discovered in 2011, Chibondo became a politically charged heritage site, officially framed as a symbol of liberation while simultaneously raising allegations that it contains victims of post-independence violence, including the Gukurahundi massacres. Employing the theoretical frameworks of difficult heritage, transitional justice, and memorialization, this research explores the political, social, and ethical complexities that emerge when nations confront traumatic pasts. Through a mixed-methods approach that combines semi-structured interviews, direct observations, and scholarly reviews, the study critically assesses …

Comparative Analysis Of Out-Of-Pocket Expenditures On Authorized Generics And Independent Generics Among Medicare Beneficiaries, Arman Arabshomali

Electronic Theses and Dissertations

Modeling Capillary-Gravity Wave Scattering With Contact Lines And Meniscus, Guoqin Liu

Electronic Theses and Dissertations

Capillary–gravity wave scattering is crucial in fluid systems governed by gravitational and surface tension forces, yet classical theories often neglect key boundary and geometric effects. This dissertation examines two influential mechanisms—dynamic contact line conditions and meniscus curvature—that significantly affect wave behavior at smaller scales.

First, a semi-analytical framework is presented to show how dynamic contact lines, modeled by an effective-slip boundary, alter wave reflection and transmission around a fixed, semi-immersed cylindrical barrier. Using linear potential flow theory combined with conformal mapping and integral-equation methods, the study quantifies how barrier geometry, Bond number, and slip parameters shape energy dissipation. It identifies …

Quantification Of Auxin-Cytokinin Response During Primary Root And Lateral Root Development In Common Bean, Gurdeep Singh

Electronic Theses and Dissertations

Roots support water and nutrient uptake, anchorage, and soil interactions through continuous growth at the primary root tip (PRT). In common bean (Phaseolus vulgaris), new cells are produced in an open root apical meristem and subsequently elongate in the elongation zone, and together these processes drive root tip progression through the soil. Lateral roots (LRs) arise in the differentiation zone, where pairs of pericycle founder cells dedifferentiate, divide asymmetrically, and form lateral root primordia (LRP) that pass through defined developmental stages before emergence. Auxin and cytokinin (CK) are central regulators of both primary root growth and LR development, yet their …

Quantifying Landscape Variability Of Dynamic Soil Properties In The James River Valley, Eastern South Dakota, Sage Reuter-Schmitt

Electronic Theses and Dissertations

Dynamic soil properties (DSP) are a great tool for monitoring land-use change, and they are frequently used as soil health metrics. The NRCS and other soil researchers often use repeating, single-point or nested-point DSP studies to monitor and better understand the effects of land management decisions. While these studies capture the temporal variability of DSPs, they overlook the field-scale spatial variability of DSPs. Soil organic carbon (SOC) provides critical services to the ecosystem and other environments. These traits, as well as its susceptibility to management decisions, make SOC an important soil health indicator and DSP. Measuring SOC is often time …

Management Strategies To Improve Gastrointestinal Health And Productivity Of Native And Dairy-Derived Steers Fed In Confinement, Becca B. Grimes Francis

Electronic Theses and Dissertations

The objective of this dissertation was to evaluate strategies to mitigate metabolic disorders in confinement fed steers. The first study was conducted on yearling beef steers to investigate the effect of a rumen buffer, calcium magnesium carbonate (CMC), when fed with or without tylosin phosphate (TYL), on growth performance, rumination activity and liver abscess prevalence. Supplementation of a rumen buffer was not an effective alternative to a feed-grade antimicrobial for the control of liver abscesses in beef steers. Supplementation of CMC reduced DMI, thus negatively influencing BW and ADG. No associative effects of CMC and TYL were observed for any …

Deciphering Genetic Contributions To Antibiotic Persistence: Insights From Multi-Gene Knockout Studies, Elise K. Schweer

Electronic Theses and Dissertations

Antibiotic resistance is a critical global health challenge, complicating efforts to treat bacterial infections effectively. Antibiotic persistence plays a significant role in driving resistance. Persisters are a subpopulation of non-dividing bacterial cells that often evade lethal antibiotic treatment. Once antibiotics are removed, these cells "resurrect," resuming growth and may lead to relapsing infections. Notably, the progeny of persister cells exhibit a heightened tendency to acquire mutations or incorporate antibiotic resistance genes, further compounding the challenge of antibiotic resistance. In our recent study, we knocked out seven hypothetical genes and observed a significant reduction in persister levels. Compared to the wild …

Crisis Of The Closed Society: The Southern Historian's Battle Against The Lost Cause, 1900-1963, Julian Flesch

Electronic Theses and Dissertations

While the Lost Cause of the Confederacy pervaded every aspect of white Southern social, political, cultural, and intellectual life, it did not go unchallenged, even among white Southerners. While many white Southern intellectuals, especially historians, promoted the Lost Cause and white supremacy as objective fact, there were always historians who opposed it. This thesis will trace several professional historians, and other intellectuals who went against Lost Cause orthodoxy from the turn of the century until the 1960s. The main historians to be discussed here are William Dodd, John Spencer Bassett, Enoch Banks, and James Silver. Often, Confederate heritage organizations, newspaper …

Peptide helical content was assessed without or with Fos12 detergent using circular dichroism spectroscopy. Fluorescent-tagged peptides were used to assess binding affinities and stoichiometries to recombinant Bax, after correction for non-specific binding using bovine serum albumin. Affinities for VDAC1 and VDAC2 were three- to six-fold, respectively, lower than for the Bim BH3 domain, but all three peptides …

Storytelling In Context: How Resources Enable And Constrain The Stories Entrepreneurs Tell, John J. Rogers

Electronic Theses and Dissertations

This dissertation investigates how entrepreneurial storytelling is shaped by and shapes its material and cultural context, extending the Theory of Cultural Entrepreneurship (TOCE). While TOCE highlights storytelling as a mechanism through which entrepreneurs construct legitimacy and secure resources by drawing on culturally resonant narratives, prior research has largely overlooked the constraining and enabling role of material resources in this process. This dissertation addresses this gap by examining how context functions, not merely as a backdrop but as a constitutive force in entrepreneurial storytelling. Using ethnographic methods, two studies were conducted at a regenerative farm and processing facility in rural Mississippi. …

“Listen To The Angels Shouting”: Witnessing, Erasure, And The Legacy Of John Wesley Work Iii, Kennedy Uselton

Electronic Theses and Dissertations

Questions surrounding the relationship between erasure, music, and memory are deeply embedded within contemporary academic discourse. Music and its makers are continually remembered, forgotten, rediscovered, and lost. How we frame these conversations about memory is especially critical when considering the legacy and cultural remembrance of the Blues. This includes acknowledging that the truth of musical memory extends beyond the artists themselves—it includes those who document, study, and shape how the Blues is archived, interpreted, and narrated. This thesis addresses these questions of memory and erasure through a reconsideration of the figure of John Wesley Work III (1901–1967), a Black scholar, …

In Defense Of Intellectual Autonomy, Paisley Agyare Boaitey

Electronic Theses and Dissertations

Recent attention in virtue and social epistemology has been devoted to analyzing intellectual virtues. However, intellectual autonomy is underappreciated and has been underexplored. The lack of specificity about the formal character of autonomy makes evaluating it as an intellectual character trait and virtue difficult. Here, I will examine extant accounts of intellectual autonomy and show why puzzles about them remain. I then offer intellectual autonomy under a compositional framework. Ultimately, I aim to show that intellectual autonomy—when adequately conceived—is a viable intellectual virtue that epistemic agents in an intellectual community [ought] to cultivate and maintain.

On Developing A Behavioral Paradigm To Measure Intolerance Of Uncertainty: The Ambiguous Approach Index, Heather Clark

Electronic Theses and Dissertations

Research in clinical psychology over the last 40 years has solidified intolerance of uncertainty (IU) as an important transdiagnostic etiological and maintenance factor of affective psychopathology. Theoretically, IU is the dispositional cognitive tendency underlying anxiety related avoidance behaviors, such as worry, checking, and hypervigilance which lead to increased functional impairment. IU is associated with increased severity of numerous psychological concerns including anxiety, depression, and other commonly comorbid conditions. Further, higher levels of IU are found in clinical than non-clinical samples, emphasizing its role in mental health outcomes. However, behavioral paradigms used to differentiate between individuals of different diagnostic groups or …
