Emotional Intelligence And Self-Efficacy In Relation To Turnover Intention: The Mediating Role Of Job Satisfaction And Organizational Commitment In Faith-Based K–12 Education, Nestor Osorio

Dissertations

Problem

Leadership turnover remains a significant challenge within faith-based K–12 educational systems, affecting organizational stability, school culture, and long-term institutional effectiveness. Although previous studies have examined turnover intention in educational leadership, limited research has explored how emotional intelligence and principal self-efficacy relate to turnover intention through organizational attitudes such as job satisfaction and organizational commitment within faith-based educational settings. Additionally, little empirical research has focused specifically on educational leaders serving within the North American Division (NAD) of Seventh-day Adventist schools. This study examined the extent to which emotional intelligence, principal self- efficacy, job satisfaction, and organizational commitment are associated with …

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 …

Thermodynamic Properties Of Cluster Outskirts, Leo Moraczewski

Dissertations

We present the temperature, density, entropy, and pressure profiles of the intracluster mediums of eight galaxy clusters observed out to the virial radius with complete azimuthal coverage by the Suzaku X-ray space telescope. Suzaku’s low background was vital to probing the lower x-ray surface brightness of cluster outskirts that could not be studied by X-ray telescopes such as Chandra and XMM-Newton which have a higher background level. The eight clusters being examined are the last observed out to the virial radius by Suzaku that have not had their properties published. As all eight clusters have complete azimuthal coverage, we also …

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 …

Constructing Effectiveness: Culture, Legitimacy, And Strategic Planning In Zoos And Aquariums, Robin Keith

Dissertations

Zoos and aquariums are complex organizations operating with multiple mandates—saving species, providing exceptional care to animals, connecting communities with nature, and inspiring environmental action—making “effectiveness” difficult to define. What counts as success depends on who is asked and which goals are foregrounded. This study investigated how stakeholders in Association of Zoos and Aquariums (AZA)–accredited organizations conceptualize and operationalize effectiveness within strategic planning processes. Prior research on nonprofit and mission-driven organizations has shown effectiveness is multidimensional and often defined differently by various stakeholders. However, little has been known about how these definitions are negotiated through the practice of strategic planning, …

Investigation Of A Flux Compression Magnetic Nozzle For Pulsed Plasma Propulsion, Zachary K. White

Dissertations

A key part of any propulsion system is how the energy of the propellants is used for thrust. Because of the high temperatures of nuclear fusion plasma, traditional methods like guiding the propellant with walls are not feasible, so instead, electromagnetic forces must be used to avoid physical contact between the propellant and the vehicle. Usually, to do so the physical nozzle is replaced by a magnetic nozzle where the physical walls are replaced by magnetic fields. This thesis focuses on the direct imaging and probe measurements of a laser produced plasma expanding into a magnetic field as analogous event …

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). …

Role Of Mkp-2 In Pancreatic Beta Cell Function & Development Of Diabetes, Nabin Ghimire

Dissertations

Diabetes mellitus is a chronic metabolic disease characterized by persistent hyperglycemia. Type 1 diabetes results from autoimmune destruction of β-cells, whereas Type 2 diabetes is associated with obesity and insulin resistance. Type 2 diabetes (T2D) and metabolic-associated fatty liver disease (MAFLD) are closely linked, as individuals with T2D are twice as likely to develop MAFLD. Previous work from our lab demonstrated that overexpression of MKP-2 in obesity promotes hepatic steatosis, diet-induced obesity, reduced insulin sensitivity, and increased body weight. However, the role of MKP-2 in the onset and progression of diabetes remains unclear. The objectives of this study were to …

Utility Of Model-Based And Probabilistic Approaches For Rocket Engine Affordability : Exemplified On The Rs-25 Engine, Shreyas Lakshmipuram Raghu

Dissertations

Rocket engine development has historically relied on test–fail–fix (TFF) methodologies to uncover structural and fatigue deficiencies under representative operating conditions. While effective, TFF is inherently costly and schedule-intensive, often revealing life-limiting behavior late in the development lifecycle. The increasing use of additive manufacturing (AM) amplifies this challenge by introducing material property scatter and process-induced variability. Without explicit early treatment of uncertainty, these effects can increase reliance on physical testing and drive additional TFF cycles. This work presents a reliability-driven life-consistent design-bounding framework intended as an early lifecycle decision-support tool to assess and mitigate TFF risk. Although material variability is inherently …

Exploring Pregnancy-Related Empowerment And Person-Centered Prenatal Care In Black Pregnant And Postpartum Women In Alabama, Lauren Milam

Dissertations

Black women in the United States experience disproportionately high rates of maternal morbidity and mortality and often report feeling unheard, dismissed, or excluded from decision-making during pregnancy and childbirth. Understanding how Black women experience prenatal care and how those experiences relate to empowerment during pregnancy is essential for improving care and addressing persistent inequities. This study examined the relationship between person-centered prenatal care and pregnancy-related empowerment and explored Black women’s prenatal care experiences in Alabama using a sequential Quan → QUAL mixed methods design. In the quantitative phase, relationships among person-centered prenatal care, pregnancy-related empowerment, and care-related factors were examined …

Human Perceptions Of Social Intelligence In Large Language Models, Derek Koehl

Dissertations

This dissertation investigates how users form perceptions of social intelligence and trust when interacting with large language model chatbots. Three experimental studies manipulated chatbot agreeableness, goal orientation, and simulated short-term memory, measuring perceived social intelligence and trust. The primary finding is an asymmetric effect of personality: disagreeable chatbot behavior produced large reductions in perceived social intelligence and trust, whereas agreeable behavior produced negligible gains above a warm baseline, consistent with negativity bias in social cognition. Goal orientation did not independently enhance perceptions but functioned as a contextual moderator. Simulated memory produced medium-to-large increases in perceived social intelligence without reliably increasing …

Diffusion Of Excitons In Thin Films Of Quantum Dots, Dustin Roberts

Dissertations

Quantum dots are heavily used in modern devices, such as consumer television screens, lasers, medical sensors, solar cells, and quantum computing. Their tunability and photo-stability make them candidates for a variety of applications which formerly required either dyes or significant amounts of band structure engineering. Despite all of the current and active applications, there is a gap in the current literature with regards to how energy is transported through thin films of quantum dots, and what methods may be used to control transport direction and range. The goal of this dissertation is to help fill those gaps, towards the end …

Sharing Patient-Generated Health Data With Electronic Health Record: A Standardised Provenance And Context-Rich Information Model And Clinician Evaluation, Abdullahi Abubakar Kawu

Dissertations

With the advent of Patient-Generated Health Data (PGHD) through wearable, mobile, and home monitoring systems, there is immense potential for ongoing monitoring and patient engagement. But integrating PGHD with Electronic Health Record (EHR) is challenged by sub-optimal support for contextual metadata and its relevant elements, lack of semantic interoperability among disparate systems, poor knowledge regarding the factors that impact clinician acceptance, and absence of globally agreed standards for data exchange. This thesis explores how contextually relevant patient-generated health data can be shared with EHRs through a FAIR standardized information model that ensures semantic and syntactic interoperability.

The study addresses six …

A Qualitative Case Study Exploring The Processes And Criteria For Presidential Leadership Selection In Three United States Higher Institutions Of Learning, Gabriel Kofi Boahen Nsiah

Dissertations

Background of the Problem

Today, research on U.S. higher education presidential search processes is limited, and existing literature characterizes these searches as reactive postures that are secretive, closed-door practices that have not adapted to the early signals of external seismic change. According to Quincy Martin (2021), “the world has evolved (p. 99).” Therein lies the problem. Quincy Martin insists, “Higher education has entered a period of upheaval, aided by new technologies, but hampered by political and cultural shifts. These are only amplified by modern, warp-speed information-sharing practices. All of this has exacerbated the consequences of scandals that threaten the stability …

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 …

Teacher Self-Efficacy Perceptions For Technology Integration And Social Media Use As Instructional Tools: Future Implications For Pedagogy In Trinidad And Tobago, Paula Edwards Sealey

Dissertations

Problem

As the educational landscape in Trinidad and Tobago evolve post COVID-19, gaining an understanding of the purpose of teachers in the implementation of national and ministerial ICT policies seem imperative. The exploration of teacher’s personal belief about their ability to effectively infuse technology and social media with their traditional teaching practices, may provide much needed insight about the role that teacher self-efficacy plays in this educational shift (Caner & Aydin, 2021; Phillip & Cain, 2015). Very few studies in the local and regional literature involve teacher self-efficacy as a variable of interest. Moreso, there has been no research to …

A Phenomenological Qualitative Study Of The Experiences Of Board Chairs Toward Governance In Seventh-Day Adventist Schools Across Canada, Shad Lehmann

Dissertations

Problem

There is limited understanding of how school board chairs within the Canadian Seventh-day Adventist education system perceive and carry out their leadership and governance roles. The role of the board chair is complex, involving oversight of the organization, adherence to denominational policies, and alignment with the school’s academic and spiritual missions. Although effective governance is vital for school success, there remains a lack of clarity about how board chairs interpret their roles, fulfill their responsibilities, and navigate the unique demands of faith-based school leadership. This gap in understanding restricts the system’s ability to provide appropriate training, support, and clear …

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 …
