“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, …

A Model For Understanding Anxiety And Practices To Alleviate It As It Relates To Divine Sovereignty And Human Free Will, Patrick K. Prentice

All Electronic Theses and Dissertations

This research focuses on the lack of practices that address emotional anxiety in rural church attendees in Southwestern Iowa caused by the apparent absence of control over situations that require trusting divine sovereignty or human free will. The research theorized that the anxiety of rural church attendees in Southwestern Iowa is caused by inadequate control over adverse situations. As a result, adverse impacts were always considered harmful. However, according to Scripture, what an individual perceives as harmful is always used by God for their good in some manner. Thus, anxiety seems rooted in a desire to avoid perceived harm rather …

More Than What You Say: Nonverbal Communication In The 21st Century, Stephanie Montgomery

Textbooks

Nonverbal communication is a distinct form of communication, transcending the spoken word. It is communication through our gestures, eye behavior, vocalics, and body language. Nonverbal communication is often misinterpreted, though, because accurate interpretation depends on a variety of skills. This is not an easy or natural ability. However, with education, awareness, and training, errors can be minimized.

Pro-Government Militias And Political Instability: The Consequences Of Outsourced Regime Security, Ben J.A. Leo

Theses and Dissertations--Political Science

The state is often conceptualized as an entity with a monopoly over the use of force within some set borders. Yet, more and more frequently, states allow or deliberately create friendly non-state military organizations. Five-hundred and four of these groups, known as Pro-Government Militias (PGMs), were observed between 1981 and 2014 and were present in a little more than thirty percent of country-years in that timeframe (Carey et al. 2022). Moreover, while some groups are relatively small and weak, many constitute a considerable military force within their country and beyond. For example, the Xinjiang Construction Corps in China, which maintains …

Special Educator Persistence: Unveiling Teacher Perceptions, Janet Nutt

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

There is a continually growing shortage of special education teachers (SET). The shortage is so dire that the U.S. Bureau of Labor Statistics (2024) anticipates that as many as 35,900 new SET will be needed each year for the next decade. One of the leading factors contributing to the shortage of special educators is attrition, or any loss of teachers from their positions (Darling-Hammond, 2003; Ingersoll, 2001). Teacher persistence, therefore, is a critical concern in addressing the teacher shortage. The purpose of this mixed-methods research study is to examine the association between previously identified factors of attrition and SET decisions …

Evaluating A Naturalistic Language Intervention With Students With Complex Communication Needs In An Elementary Classroom, Kristina M. Johnson

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

Communication is an essential skill for all students, but specifically for students with moderate to severe disabilities. Through communication, our students with disabilities express their wants and need, make and maintain relationships, and participate in daily activities at home, school, and in the community. Play is a natural and motivating activity that encourages communication in all settings. Thus, I looked at using naturalistic language intervention (NLI) as an intervention strategy to increase expressive communication skills in my students with expressive language deficits. This project aimed to increase expressive communication skills in three elementary students with moderate to severe disabilities by …

Recent advances in the integration of high-speed mobile networks and real-time IoT devices have facilitated in building of smart warehouses, where a set of beacons and Internet of Things (IoT) devices (or source nodes) can monitor the status of various physical processes in a time-critical way. In real-time status monitoring systems, like smart warehouses, quantifying the freshness of the Internet of Things (IoT) data based on the age of information (AoI) metrics becomes quite crucial. As source nodes are battery-constrained, a balanced trade-off between AoI minimization and preservation of source node battery energy is essential. In this paper, in a …

Faithful Narratives From Complex Conceptual Models: Should Modelers Or Large Language Models Simplify Causal Maps, Tyler J. Gandee, Philippe J. Giabbanelli

VMASC Publications

(1) Background: Comprehensive conceptual models can result in complex artifacts, consisting of many concepts that interact through multiple mechanisms. This complexity can be acceptable and even expected when generating rich models, for instance to support ensuing analyses that find central concepts or decompose models into parts that can be managed by different actors. However, complexity can become a barrier when the conceptual model is used directly by individuals. A ‘transparent’ model can support learning among stakeholders (e.g., in group model building) and it can motivate the adoption of specific interventions (i.e., using a model as evidence base). Although advances in …

An Exploratory Approach To Understanding Assessment Errors On Measures Of Executive Functioning, Gurjot Mondair

PCOM Psychology Dissertations

The global risk of dementia due to longer lifespans and increased medical interventions necessitates accurate diagnosis of cognitive decline. Thus, the utilization of neuropsychological testing to diagnose disorders of cognitive decline should seek to ascertain multiple data, including success/failure of cognitive tasks and evaluation of error patterns. The purpose of this study was to examine the frequency of executive function (EF) errors across diagnoses of cognitive decline (age-related cognitive decline [ARCD], mild cognitive impairment [MCI], vascular dementia [VaD], frontotemporal dementia [FTD], Lewy body dementia [LBD], and Alzheimer’s disease [AD]) and to examine whether the specific types of EF errors (intrusion, …

The Blank Paper Method: An Independent Retrieval Protocol, Kevin Gregorio

PCOM Psychology Dissertations

Most students struggle with effective self-study, often relying on passive strategies like rereading instead of active techniques such as retrieval practice, which research shows enhances learning and long-term retention. To address this issue, this study introduced and evaluated the Blank Paper Method—a structured free recall protocol designed to encourage self-regulated retrieval practice. The study explored two key questions: (1) Does the Blank Paper Method improve test performance compared to students’ default study habits? (2) Will students voluntarily adopt this method over time, demonstrating self-regulated learning? The study involved 56 incoming high school freshmen at a private college-preparatory school in Philadelphia. …

Characterization Of P38alpha And Nitric Oxide Synthase 3 Binding, Gillyan M. Jewett

Master's Theses

P38alpha is a member of the mitogen activated protein kinase (MAPK) family. This family is important for mediating signal transduction pathways through phosphorylation of downstream substrates. Previous work has described the ability of p38alpha to bind and phosphorylate nitric oxide synthase 3 (NOS3) at two sites, the autoinhibitory loop (AI) at S600 and the N-terminal MAPK binding site (NtMAP) at S114. P38alpha has two substrate binding domains, the common docking groove (CD-groove) and a hydrophobic pocket (DEF) that are important in binding and phosphorylating various substrates specific to each pocket. Utilizing biolayer interferometry, this work describes the importance of both …

Early Season Tropical Cyclones Affect Birds Breeding On A Barrier Island, Theodore J. Zenzal Jr., Amanda N. Anderson, Brock Geary, Jessica Schulz, Robert C. Dobbs, Wylie C. Barrow Jr., James H. Waddle

Gulf and Caribbean Research

Animal populations often experience acute natural disturbances, most of which are connected to short—term weather events. Occurrences of early—season tropical cyclones during the peak of the avian breeding season are likely to increase with climate change, which can substantially impact populations of coastal breeding birds at multiple scales. To understand the acute impacts of severe tropical cyclones, we investigated how abundances of breeding birds changed before and after 4 early season named tropical cyclones on a barrier island in the Gulf of Mexico. We detected a change in pre— versus post—storm numbers of breeding birds after 2 out of 4 …
