Thermal Analysis Of The Fiber Fuse Effect, John Seekins

Dissertations

The fiber fuse effect is a self-sustaining damage propagation mechanism that can occur in the core of optical fibers. Under sufficient levels of applied power, laser light is absorbed as heat in the fiber. This phenomenon is characterized by a brightly glowing spot in the fiber that propagates towards the source of laser light at about 1 𝑚/𝑠. A numerical simulation of the fiber fuse effect is developed that solves the transient heat equation with source terms in cylindrical coordinates utilizing an explicit finite difference discretization. For the first time in a simulation of this type, a radiation transport equation …

Math Anxiety, Math Self-Concept And Math Self-Efficacy: A Study Of The Jingle-Jangle Fallacies, Marsha Natasha Durrant-Walker

Dissertations

Problem

The overlap and lack of clear distinction among the constructs of math anxiety, math self-concept, and math self-efficacy presents issues for research and practice. The literature reveals that math anxiety is closely linked to math self-concept (Klee et al., 2022). Additionally, math self-concept and math self-efficacy often overlap and are not easily distinguishable (Kranzler & Pajares, 1997; Pajares & Miller, 1994; Pajares & Urdan, 1996). Each of these constructs has been shown to play a critical role in student math achievement (Timmerman et al., 2016). -- When constructs are not defined or measured distinctly, inconsistencies may emerge in research …

A Qualitative Multiple Case Study Exploring Shifts In Thinking Of Principals Through Initiatives To Foster Relational Leadership Conducive To Retaining Teachers In High-Minority, High-Poverty Public Schools, Rita Seay

Dissertations

Problem

The public education system is broken, and teacher shortages have reached a crisis, especially in some specialty fields in United States (Carrillo & Salhotra, 2022; Podolsky et al., 2016). Lately, the teacher workforce has been described as a “leaky bucket” (Podolsky et al., 2016, p. 1). Indeed, the problems are complex in poor socioeconomic communities with racial and ethnic groups of students because teachers struggle to make a difference and, in most cases, fail due to insurmountable situations that are beyond their scope of influence (Rondfeldt et al., 2013). Evidence published that students suffer immensely from a broken, segregated …

Generative Ai Professional Development Program For Higher Education Instructors, Sheena Bahra

Dissertations

As technology progresses and brings enhanced forms of artificial intelligence (AI), such as generative AI (Gen AI), it continues to affect education by introducing opportunities and challenges in its application to higher education teaching. Advances in technology can make instructors reluctant to use applications, leading to missed learning and skill-development opportunities for higher-order thinking skills. This study investigates how AI professional development (PD) training can influence higher education instructors’ willingness to use Gen AI in the classroom. This study employed a qualitative instrumental case study design informed by an exploratory lens. The study investigated instructors’ use of Gen AI in …

The Effects Of Bilingual Services In Adaptively Leading Shared Parishes, John Patrick Cahill

Dissertations

Shared parishes are churches that have services in more than one language. Pastors struggle with how to lead, unify, and pastorally respond as populations shift and demographics change. One-third of the Catholic parishes in the United States have Mass in more than one language every Sunday. Leaders need to adapt by exploring bilingual services as a way to be more effective and inclusive. This descriptive quantitative study examined three blocks of parishioners at a particular shared parish: (a) those who attend Mass in English, (b) those who attend Mass in Spanish, and (c) those who attend the bilingual Mass. A …

Recruitment Of Black Minority Community Into Irish Police: Evaluating The Dynamics Of Culture In Decision-Making., Adeyemi Adekanle

Dissertations

Ethnic and racial diversity in police services has been a focus for criminologists and policing scholars for some considerable time. But despite intense efforts, most multicultural societies still struggle to get Black minority communities recruited into their police services. Two widely held interconnected assumptions appear to be at issue. The first is that police occupational culture, which has been shown in some studies to be prejudicial, is, in many cases, blatantly racist. This may well be a catalyst or “push factor” in discouraging members of Black communities in particular from taking up police careers. The second is that members of …

Match Or Mismatch? : The Effects Of Fingerprint Evidence And Expert Testimony On Jury Decisions, Kassie N. Thallas

Dissertations

Fingerprint evidence is widely perceived as objective and reliable, yet is typically presented to jurors through expert testimony rather than directly evaluated. The present study examined how fingerprint match status and expert testimony influence juror decision-making. Participants (N = 225) read a mock criminal trial summary and were randomly assigned to one of five conditions. Four conditions were derived by crossing Expert Condition (fingerprint expert alone vs. conflicting experts) and Match Status (match vs. no match), with an additional control condition without fingerprint evidence. The participants made verdict decisions and rated the credibility, honesty and believability of the expert. The …

Exploring Detached Concern, A Dual-Process Emotional-Regulation Strategy, Among Intensive Care Nurses Providing End-Of-Life Care In The United States, Melissa Milton Miasek

Dissertations

Intensive care unit (ICU) nurses repeatedly provide end-of-life care (EoLC) and experience significant emotional distress, burnout, and moral distress that can lead to leaving the profession. Detached concern (DC), a dual-process emotional-regulation strategy which balances empathetic concern with emotional detachment, may support ICU nurses' emotional well-being; however, DC among nurses remains vastly understudied. This qualitative descriptive study gained deeper understanding of DC among ICU nurses providing EoLC in the United States. The study was guided by a conceptual model adapting Lampert and Glaser's dynamic DC process within Elfenbein's emotional regulation framework. The overarching research question explored ICU nurses' perspectives on …

Perception Matters: A Case Study Exploring How Belief Systems Affect Family-School Partnerships And Family Literacy Initiatives In A Title I School, Kwtay Calvin

Dissertations

Family-school partnerships have been shown to have positive effects on students’ overall performance in school. However, in many instances schools have not used partnerships effectively to support literacy learning, particularly for Black families. Teacher bias, negative perceptions, and lack of cultural responsiveness hinder teachers’ effort to build meaningful relationships with Black families to best support family literacy. This qualitative study aimed to examine family-school partnerships through the experiences of school principals, teachers, and Black families to gain insight into the factors that impact collaborative relationships and family literacy support. This study is framed in critical race theory, the theory of …

The Desecration Of Sacred Spaces In The Dead Sea Scrolls And Pre-Nicene Latin Christianity: A History Of Interpretation Of The Eschatological Motif Of The Defiling Enemy In Apocalypticism, Rodrigo De Galiza Barbosa

Dissertations

Problem

The motif of the polluting enemy in the sanctuary is an important point of departure in the articulation of community boundaries in Hebraic-Christian culture. This particular motif has the potential to explain, at least in part, how Jewish and Christian communities would have understood the apocalyptic evil other and, from this understanding, set boundaries for their holy communities. Texts such as Dan 8 and 2 Thess 2 have been the locus classicus of the so-called antichrist, and ever since their interpretation has shaped how Christians and Jews have understood the enemy to their respective communities. In the history of …

A Hierarchical, Data-Driven Analytical Paradigm For Strategic Planning, Operational Decision-Making, And Resilience Enhancement In United States Electric Power Systems Under Extreme Demand Conditions, Anyama Hanson Tettey

Dissertations

Historical evidence indicates that the United States electric power grid continues to face persistent criticism for reliability challenges during peak demand conditions. Extreme ambient temperatures are a primary driver of such peaks, rendering the grid most vulnerable precisely when electricity demand is highest. These demand surges are largely driven by coincident operation of heating, ventilation, and air-conditioning systems across customer classes, a trend expected to intensify as sectors such as transportation increasingly rely on electrification. Efforts to mitigate demand related unreliability have traditionally focused on system-level demand forecasting and planning, typically at the scale of cities or entire utilities. However, …

Threatened To Testify : Juror Perceptions Of Coercive Eyewitness Interviews, Alexa A. Mecikalski

Dissertations

The effects of coercive investigative questioning techniques have been extensively studied in the context of suspect interrogations; however, few studies have evaluated outcomes related to coercive questioning of eyewitnesses. Therefore, the present study investigated mock juror perceptions of the use of interrogation tactics during eyewitness questioning. Participants read a trial summary and provided trial judgments (e.g., verdict, eyewitness credibility, perceived coerciveness of the interview) pertaining to a case in which an eyewitness is questioned using either (1) maximization tactics (e.g. high pressure questioning, threats), (2) minimization tactics (e.g., minimizing severity or consequences), or (3) no tactics (e.g., statement provided voluntarily). …

Thermodynamics Of Bubble-Through Liquid-Core Nuclear Thermal Rockets, Dakota John Santana

Dissertations

Liquid-Core Nuclear Thermal Rockets (LNTR) were originally investigated in the 1960s. Exploratory efforts have thus far been relegated to preliminary models that illustrate proof-of- concept or identify theoretical limits. Collectively they would report ranges for 𝐼𝑠𝑝 between 1000 −2000 𝑠 and thrust-to-weights between 0.5 −6. This work expands a model for the Bubbler class of LNTRs into an engineering model suitable for design exploration and system model integration. Bubblers use centrifugal force to trap molten fissile fuel while bubbling propellant radially inward to cool structural members and achieve temperatures >4500 𝐾. The Bubbler model detailed herein, dubbed Fornax, expands the …

Narrating Institutional Becoming: Faith, Leadership, And Identity Reconstruction During A College-To-University Transition, Viviene H. Dyer

Dissertations

Problem

The contributions of faith-based higher education institutions to the tertiary landscape in small island developing states are insufficiently addressed in the scholarly literature. Consequently, there is limited understanding of how these institutions navigate organizational transitions and respond to capacity gaps that the public sector is unable to fill within dynamic cultural and regulatory environments. This gap is especially evident for Seventh-day Adventist institutions, whose efforts to preserve mission and identity during periods of institutional change remain underexamined and poorly documented.

Purpose

The purpose of this narrative inquiry study was to examine how university administrators influenced the development and ongoing …

Continuity And Development In The Eschatological Sabbath: Themes In Seventh-Day Adventist Thought (1842–2020), Joseph Nesbit

Dissertations

The Topic

This dissertation explores continuity and development in the eschatological understanding of the seventh-day Sabbath within selected Adventist theological writings from its Millerite origins to the contemporary scholarship of Jo Ann Davidson. The eschatological aspects of the Sabbath have played a central role in both pioneer and contemporary Adventist thought, particularly in its identification as the seal of God in Revelation and as a sign of covenant loyalty in the final crisis. While this understanding has displayed remarkable continuity in its essential themes, it has also undergone significant maturation in tone, scope, and theological emphasis. By tracing both enduring …

The Symphony Of Justice: An Intertextual Study Of Social Justice Material Between The Torah And The Psalms, Daniel Gordan

Dissertations

Do passages dealing with social justice in the Torah and the Psalms together comprise an intentionally composed grand symphony, or do they merely form an ad hoc patchwork quilt in which their echoes of similarity are mere coincidences?1 Literary interactions between the Torah and the Prophets of the Hebrew Bible have been a focus of biblical scholarship, but the intertextual connections between the legal corpus of the Torah and poetry in Psalms have not received sufficient attention. Scholars have noticed some thematic similarities, but there are no systematic studies that analyze these interactions to determine whether they involve reuse and, …

The Impact Of Culturally Diverse Student Populations On High School Mathematics Teachers’ Preparations And Practices In Southern Union Conference Of Seventh-Day Adventists, Carla Thrower

Dissertations

The Problem

Across the United States and within faith-based schools recent social and political currents have amplified tensions around culture and belonging in classrooms, particularly for students from racially, ethnically, linguistically, and socioeconomically diverse communities. Evidence indicates that when schooling practices overlook students’ cultural identities or normalize a single cultural frame, students can experience marginalization and reduced access to equitable opportunities to learn (Gay, 2018; Ladson-Billings, 1995; Milner, 2010). In mathematics, a subject often perceived as culture-neutral these dynamics may surface through curriculum choices, participation norms, and expectations that do not meaningfully connect to students’ lived experiences (Aguirre, Mayfield-Ingram, & …

Validation Of The Touch/Bonding Sense Of The Five Senses Model Of Intimacy As A Spiritually Based Whole-Person Lifestyle Approach To Intimacy In Dating And Marital Relationships, Karen J. Holland

Dissertations

Problem

Intimacy is in crisis and is being culturally defined and redefined through a number of influencing factors. These include the ongoing development of individualist and narcissistic relationships; the fragmentation of human wholeness; the influence of social media and an increasingly entertainment focused society; the permeation of technology influencing personal choice and lifestyle, including the use of generative AI; and the diminishing influence of Judeo-Christian principles and values as key drivers in the development of life-long marriage relationships. This study seeks to address the need for establishing a foundation for relational intimacy based on the biblical relationship demonstrated by God’s …

A Case Study Of California Postsecondary Faculty Collaboration On Rubric Development To Foster Student Learning, Emmanuel Kwadwo Frimpong

Dissertations

Although perceived as the ‘gold standard’ strategy for conquering complex problems, collaboration can be ignored by intellectuals who prefer to work independently. This oversight may occur even in the face of challenging problems such as assessment of scholarships, institutional effectiveness, strategizing, and even the crafting of effective rubrics for assessing student learning. The scholarly literature clearly reveals that real difficulties often refuse to respond to routine assignments or common bureaucratic patterns. Additionally, 21st century conflicts may require creative solutions involving interdependence, joining of forces and brains, or vision sharing. Effective assessment of student learning within higher education may reflect just …

Associating Emotional Intelligence, Cultural Intelligence, And Inclusive Leadership: A Correlational Study Of Seventh-Day Adventist Pastors And Church Leaders In Canada, Damson Anim Oppong

Dissertations

Problem

In an increasingly polarized world, church leaders are expected to foster inclusion, belonging, and unity within diverse congregations. Inclusive leadership (IL), supported by emotional intelligence (EQ) and cultural intelligence (CQ), may offer a relational leadership posture well-suited to this challenge. Growing evidence suggests that relational qualities such as EQ and CQ help leaders develop inclusive communities, foster belonging, and bridge differences (Thomas & Inkson, 2017; Wise, 2022). Emotional and cultural intelligence are studied increasingly in organizational settings, but little is known about how they affect inclusive leadership in faith-based institutions, such as among pastors and church leaders in the …

The In-Between: Poetic Counter-Narratives Reimaging The Canon, Yisheika Lawrence

Dissertations

This qualitative, arts-based study examined how tenth grade students in a rural early college Multicultural Literature course engaged with and reinterpreted canonical texts through poetic counter-narratives. Grounded in culturally responsive pedagogy (Ladson-Billings, 1995), culturally sustaining pedagogy (Paris & Alim, 2017), and poetic inquiry (Faulkner, 2019), the study explored how students from marginalized backgrounds used poetry to articulate identity, resist erasure, and construct belonging within an academic context that often privileges dominant cultural narratives.

Data sources included 22 student poems, five semi-structured interviews, four end-of-unit reflections, and researcher memos. Analysis used a triangulated approach: qualitative coding in ATLAS.ti, computational text analysis …
