“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, …

Examining Stress, Stress, Potentially Traumatic Events, Posttraumatic Stress Disorder, And Emotional Support Among Individuals With Skin Disease Symptoms, Taylor A. Strange

Electronic Theses and Dissertations

This study investigated the complex interplay between psychological stress, trauma-related experiences, and skin disease symptoms, alongside the potential moderating role of emotional social support. While the worsening effect of stress on skin conditions is well-documented, the specific association between trauma and dermatological symptoms, and its contribution to inflammatory responses, warrants further exploration. The stress-buffering hypothesis posits that perceived emotional support can mitigate the negative impact of stress on quality of life in chronic health conditions. This hypothesis has found support across various chronic physical and psychological ailments, yet its applicability to dermatological conditions remains less established. Our study pursued two …

Loneliness And Ambulatory Blood Pressure, Patric Justin Leukel

Electronic Theses and Dissertations

Hypertension is a major risk factor for cardiovascular diseases and is by extension associated with potentially life-threatening events (e.g., heart attack, stroke). Loneliness, which has been linked to cardiovascular health problems, may be an important risk factor for hypertension. Most studies exploring psychosocial factors and blood pressure focus on single-point measurements of blood pressure, which have notable limitations. The current study investigated the association between loneliness and markers of hypertension (i.e., mean systolic and diastolic blood pressure, mean arterial pressure dip, average pulse pressure, and AASI) in a diverse sample by utilizing an ambulatory blood pressure monitoring (ABPM) device. Sixty …

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 …

Video Comprehension Score (Vcs): A Metric For Long-Form Video Description Evaluation, Harsh Dubey

Electronic Theses and Dissertations

Existing video description evaluation metrics fail to capture the long-range chronology and semantic alignment essential for long-form descriptions. An effective evaluation metric for long-form descriptions must (i) assess global thematic alignment, (ii) measure local semantic alignment, and (iii) evaluate chronological alignment while detecting corrupted content. We introduce Video Comprehension Score (VCS), a reference-based metric, which directly addresses these evaluation requirements through three components: Global Alignment Score for thematic alignment, Local Alignment Score for local semantic alignment, and Narrative Alignment Score for chronological alignment with adjustable tolerance. We evaluate VCS on two large-scale synthetic datasets designed to test corruption detection and …

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 …

The Spatial And Temporal Dimensions Of Plant–Soil Feedback In Native Perennial Monocultures, Bret Lang

Electronic Theses and Dissertations

Plant-soil feedbacks (PSFs) describe how plants change their soil environment in ways that can either negatively or positively affect subsequent plant growth. In doing so, they offer an opportunity to connect ecological processes with agricultural practice. My dissertation examines PSFs created by native perennial monocultures, commonly used for native seed production, across time and space, and through soil legacies. Specifically, I focus on how plant species identity shapes both soil nutrient and soil microbial community responses. To address these questions, I conducted field experiments with monocultures of five forb species native to South Dakota and established plots with these species …

Impacts Of Early/Mid-Gestation Shearing On Umbilical Blood Flow And Lamb Birth Weight, Mara Johnson

Electronic Theses and Dissertations

Studies outside the USA have reported that shearing pregnant ewes during mid to late gestation increases lamb birth weight. Our hypothesis was that shearing pregnant ewes on day 50 of gestation would increase umbilical blood flow (UBF), fetal size, lambing and placental weights. Twenty-eight Polypay ewes were randomly assigned to two treatments: shorn (S) and sham-shorn (Control, CON) and divided in singleton (S: n=4; CON: n=4), twins (S: n=5; CON: n=5) and triplets (S: n=5; CON: n=5). Umbilical BF and fetal and placental measurements were obtained via ultrasonography every 10 days from day 50 to 110 of gestation. Lamb birth …

Impact Of Parental Involvement On Children’S Mental Health, Syeda Tasnime Kabir

Electronic Theses and Dissertations

This study estimates the causal effect of parental involvement on the mental health of primary school children in Bangladesh. Using an instrumental variables strategy that leverages local parental involvement norms, I find that increased parental involvement significantly reduces cognitive and emotional difficulties. Notably, I find that the protective effect of parental involvement varies by socio-economic context, showing weaker effects for children of mothers who married at an older age and those whose fathers live outside the household, but stronger effects in joint families. Furthermore, I identify two key mechanisms underlying these effects: accommodating parenting style and improved household hygiene practices. …

Camelina sativa, an oilseed crop of the Brassicaceae family, has seen increased cultivation in North America in response to the rising demand for biofuels over the past two decades. With this growth, camelina meal, a byproduct of oil extraction, has emerged as a promising yet underutilized resource, particularly for applications in animal nutrition. This study aimed to evaluate the potential of camelina meal as a substrate for submerged fungal fermentation and to examine how this bioconversion affects its physicochemical and nutritional properties. The influence of mild pretreatments (unwashed, washed only, and washed/dried and ground) on fermentation outcomes was also assessed. …

Testing The Effect Of Source And Environment On Native Seed Germination To Inform Seed-Based Restoration Of Grasslands, Brandon Clark

Electronic Theses and Dissertations

Grasslands are one of the most endangered ecosystems on the planet, and they provide a variety of important ecosystem services that people rely on. Losses of grasslands can be mitigated through restoration. Seed-based restoration is a regularly used practice due to its practicality and cost-effectiveness. Planting non-local seed that may not be suitable for its destination environment can have consequences in plant establishment and subsequent restoration success. This experiment tested the response (final germination and germination rate) of seed from 11 perennial tallgrass species sourced from 3 different locations to different germination temperature conditions. Seeds from three sources of each …

Refinement Of Trend-To-Trend Cross Calibration Total Uncertainties Utilizing Extended Pseudo Invariant Calibration Sites (Epics) Global Temporally Stable Target, Minura Samaranayake

Electronic Theses and Dissertations

Cross-calibration is an essential technique for calibrating Earth Observation satellite sensors, which involves taking nearly simultaneous images of a ground target to compare uncalibrated sensor to a well-calibrated reference sensor. This study introduces the hyperspectral Trend-to-Trend (T2T) cross-calibration technique utilizing EPICS Cluster 13 Global Temporally Stable (Cluster 13-GTS) as the calibration target, offering better temporal stability than previous targets used in T2T cross-calibration by an absolute difference of 0.4%, between coefficients of variation across all bands excluding CA band. A multispectral sensor-specific normalized hyperspectral profile was developed using the EO-1 Hyperion hyperspectral profile over Cluster 13-GTS to improve Spectral Band …

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 Planar Brownian Motion Singularly Tilted Through A Point Potential, Barkat Mian

Electronic Theses and Dissertations

We construct a family of time-inhomogeneous two-dimensional diffusion processes, defined over a finite time interval [0, T]. These diffusions have transition density functions that are given by the integral kernels of the semigroup corresponding to the two-dimensional Schrödinger operator with a point potential at the origin. Although, in a few ways, our processes of interest are closely related to two-dimensional Brownian motion, they have a singular drift pointing in the direction of the origin that is strong enough to enable the possibility of visiting there with positive probability. Our main focus is on characterizing a local time process at the …

Missing Physics Or New Physics? Understanding Biases In Gravitational Wave Tests Of General Relativity, Purnima Narayan

Electronic Theses and Dissertations

Gravitational wave (GW) observations from binary black hole (BBH) coalescences offer a powerful means of probing general relativity (GR) in its most extreme regime: the strong- field, highly dynamical merger phase. One can compare observed signals to theoretical waveform models to constrain possible deviations from GR. However, the reliability of such comparisons can be compromised by waveform systematics, especially when key physical effects are not incorporated into the models. This dissertation investigates the impact of three such missing physical effects: orbital eccentricity, strong gravitational lensing, and waveform systematics due to precession, higher-order modes, and memory on standard GW tests of …
