The Relationship Among Spirituality, Self-Efficacy, And Quality Of Life In Adults With Sickle Cell Disease, Maxine A. Adegbola

Dissertations

For the individual with sickle cell disease (SCD), the lifespan is increasing but adults report decreased quality of life (QOL), low self-efficacy, and ineffective coping skills. The care of adult patients with SCD requires a complex multidisciplinary team approach with focus not only on physiological, psychological, and social needs, but also on spiritual needs. Quality of life, spirituality, and self-efficacy have been sparsely and separately studied in individuals with SCD. These three constructs have never been combined in one study in the adult SCD population.

The purpose of this study was to explore and describe the relationships among spirituality, self-efficacy, …

K-12 Principals And Special Education: A Study Of Mississippi Principals’ Knowledge Of Special Education Policies And Procedures, Jodi Cameron-Polk

Dissertations

This study sought to assess the knowledge of Mississippi K-12 public school principals and assistant principals in special education law, policies, and procedures concerning the six principles (i.e., zero reject, non-discriminatory evaluation, least restrictive environment, free appropriate public education, due process, and parent participation) of the Individuals with Disabilities Education Improvement Act of 2004. This study also sought to establish by which method (i.e., university coursework, administrative trainings, on-the-job experiences, self-taught research, or did not learn this) they acquired their knowledge of special education law, policies, and procedures. The researcher adapted Jesteadt’s survey tool to ascertain participants’ special education teaching …

The Effects Of Disinformation Upon National Attitudes Towards The Eu And Its Institutions, Alex Murphy

Dissertations

This work explores the effects of misinformation and disinformation upon national attitudes towards the EU. Several nations, in particular the Russian Federation, have been working for decades to spread narratives that debase the political processes of healthy democracies around the world. There is strong evidence to show that extensive efforts have been made to disrupt the inner workings and overall membership of the EU, to support disruptive policies in the United States such that political deadlock is maintained indefinitely. These efforts are largely based on the spreading of misinformation and disinformation across social networks that have done very little to …

The "Othering" Of America: How The Strategic Use Of Crisis And Ressentiment Succeeded In The Trump Era, Laura J. Franklin

Dissertations

The establishment of a crisis theme through public rhetoric often triggers widespread attention, resulting in public concern and media coverage of an issue that could potentially be overblown or deceptive. In right-wing political discourse, this crisis warning is typically delivered by a White male leader with ready access to the powerful news media. An “us versus them” theme often occurs. Within this mode of a hegemonic exclusion, a culture of immigrants or an American minority are often depicted, perhaps aggressively, as a threat: A threat used to motivate, enrage and create the frustrations inherent in ressentiment. This dissertation explores the …

Analysis Of Cryptic Variation Affecting Splicing In Early-Onset Mendelian Disease, Stephanie A. Felker

Dissertations

Genetic variants with poor annotation or unknown biological consequence are often systematically excluded in genomic analysis. Here I analyze variants near "poison exons” which are often absent from standard gene annotations and are alternative exons whose inclusion results in a premature termination codon. Neurodevelopmental disorders (NDDs) often result from rare genetic variation, but the genomic testing yield for NDDs remains around 50%, suggesting some clinically relevant rare variants may be missed by standard analyses. Variants that alter poison exons inclusion can lead to loss-of-function and may be highly penetrant contributors to disease. I analyzed variants found by genome sequencing in …

Airborne Passive Microwave Geophysical Retrievals And Applications In Assessing Environmental And Aerosol Impacts On Maritime Convection, Corey G. Amiot

Dissertations

Improvements to NASA’s Advanced Microwave Precipitation Radiometer (AMPR) have yielded physically realistic brightness temperatures (T_b) from the Olympic Mountains Experiment / Radar Definition Experiment (OLYMPEX/RADEX) and Cloud, Aerosol and Monsoon Processes Philippines Experiment (CAMP²Ex). Multi-linear regression equations, developed to retrieve integrated cloud liquid water (CLW), water vapor (WV), and 10-m wind speed (WS), were tested using simulations, deconvolved AMPR T_b from OLYMPEX/RADEX, independent retrievals, and in situ data. Simulated retrievals yielded average CLW, WV, and WS root-mean-square deviations (RMSD) of 0.11 kg m^-2, 1.28 kg m^-2, and 1.11 m s^{-1 …}

Evaluation Of Communication Sciences And Disorders Graduate Student Attitudes Related To Trauma-Informed Client Interactions, Jenica Joseph

Dissertations

Problem

Communication sciences and disorders (CSD) graduate students may have trauma histories and may be ill-equipped to identify and manage trauma responses in clients. This mixed-methods study examined graduate student attitudes towards implementing trauma-informed educational practice (TIEP) methods and trauma-informed patient care.

Method

The Attitudes Related to Trauma-Informed Care (ARTIC) Scale (Baker et al., 2016) quantitatively measured pretest/posttest changes in CSD graduate student attitudes towards use of trauma-informed care with clients. Participants (n=43) were assigned to non-equivalent experimental and control groups. Groups received the pre/posttest and either an immediate (experimental) or delayed (control) trauma-informed educational session. Twenty-one participants completed focus …

The Perceived Results Of Feedback And Evaluation Of Teaching Effectiveness On Adjunct Faculty Professional Development And Growth, Luda V. Vine

Dissertations

Problem

While full-time faculty at any institution of higher learning undergo an established system of evaluation of teaching effectiveness, adjunct faculty members' experience varies greatly from institution to institution. There is little in the relevant academic literature about an effective feedback mechanism for evaluating teaching effectiveness among adjunct faculty members. Limited qualitative research has been done to understand the effects of teaching evaluations on the professional development and growth of individual adjunct faculty members. Developing an understanding of effective evaluation of teaching that will result in improved adjunct faculty professional development and growth will impact not only the faculty members' …

Mammalian Dihydropyrimidine Dehydrogenase: Employing Transient State Kinetic Methods To Determine Catalytic And Inhibitory Mechanisms, Dariush Forouzesh

Dissertations

Dihydropyrimidine dehydrogenase (DPD) catalyzes the two-electron reduction of pyrimidine bases uracil and thymine as the first step in pyrimidine catabolism. The enzyme achieves this simple chemistry using a complex cofactor set including two flavins and four Fe4S4 centers. The flavins, FAD and FMN, interact with respective NADPH and pyrimidine substrates and the iron-sulfur centers form an electron transfer wire that links the two active sites that are separated by 56 Å. DPD accepts the common antineoplastic agent 5-fluorouracil (5FU) as a substrate and so undermines the establishment of efficacious toxicity. Though studied for multiple decades, a precise description of the …

The Struggles Black Women Face In Federally Qualified Community Health Centers In South Carolina: A Phenomenological Exploration Of Women In Leadership Positions, Sharon Black

Dissertations

This qualitative interpretive phenomenological study examined the professional lived experiences of Black women who hold leadership positions within Federally Qualified Community Health Centers (FQHCs) in South Carolina. The researcher examined their experiences through the lens of Belenky’s (1986) Ways of Knowing framework, focusing on self-expression, voice, and how the participants processed their leadership experiences. In addition, the study draws on Crenshaw’s Intersectionality and Black Feminist Post-structuralist theories. The study explores the difficulties, successes, and strategies these women use, focusing on stereotypes, challenges in leadership roles, diversity of experiences, and the importance of voice themes.

The study provides practical suggestions for …

Reconstructing The Kantian Ends Of Reason: Holiness Analytically Entailing Beatitude In An Eternal Highest Good, Anthony Gudwien

Dissertations

This dissertation argues that an eternal highest good is the final end of sensible, rational agents. This final end occurs in a noumenal world – what I have labelled World Four – that has holiness analytically entailing beatitude. However, before meritorious moral agents are incorporated into this final noumenal world, they will exist in three prior worlds. World One is our current phenomenal world where sensible, rational agents can adopt a maxim to resolutely pursue holiness. World Two, which is made possible by the immortal soul postulate, is where sensible, rational agents continue their resolute pursuit in order to become …

Exploring Moral Distress Among Nurse Leaders, Preston H. Miller

Dissertations

Moral distress (MD) occurs when an individual knows the ethically correct action to take in a situation but institutional constraints prevent the individual from acting. MD is a well-documented phenomenon among nurses and occurs at a high frequency in the critical care setting. When MD is not adequately addressed and actions are not taken to mitigate precipitating factors within an organization, moral injury, moral residue, and burnout may consequentially result in nurses leaving their role or the profession. Nurse leaders are positioned to exemplify ethical leadership and provide support for their staff when MD is experienced; however, nurse leaders experience …

Measurements Of Terrestrial Gamma-Ray Flashes, Gamma-Ray Glows, And A Direct Lightning Strike From Eight Flights Of The High Energy Lightning Emission Network (Helen), Christopher Helmerich

Dissertations

The High Energy Lightning Emission Network (HELEN) campaign involved 8 balloon flights into thunderstorm environments to measure high-energy radiation phenomena like gamma-ray glows and terrestrial gamma-ray flashes (TGFs). Multiple flights detected elevated radiation levels providing evidence for theories on gamma-ray glow generation. Flight 7 measured multiple TGFs coincident spatially and temporally with lightning strikes, supporting theories of TGF origins in lightning leaders and/or return strokes. The same flight also sustained a direct lightning strike, enabling first-of-its-kind energetic radiation measurements during the propagation of the lightning strike. Radiation production was evident in both stepped leaders and return strokes, with higher flux …

“It Feels Like A Cultural Shift": Parent School Selection And Experiences With School Choice At Title I Schools, Christina Lee Ballantyne

Dissertations

A neoliberal agenda to institute educational reform via school choice has created a school marketplace where parents and schools are connected in a supply-and-demand relationship. Rather than attend the neighborhood school, some parents can seek alternative school options for their children. Although purported to improve educational outcomes and desegregate schools, school choice has not demonstrated increased student academic achievement nor integrated school spaces. Instead, the school choice movement has been seen to contribute to and perpetuate racial and economic segregation. This study sought to understand the perspectives of parents who have selected their neighborhood Title I school and how they …

Never Too Young: The Existence, Impact, And Sustainability Of Ethnic Studies In Elementary School, Angela R. Guzmán

Dissertations

Ethnic Studies has existed in higher education for more than fifty years. In high school, critical education researchers have recognized Ethnic Studies as vital to improving attendance, lowering suspension rates, and boosting GPAs for BIPOC students. This has given rise to the recent K-12 Ethnic Studies model curriculum adoption by the State Board of Education, and the signing of Assembly Bill 101, making California the first state to require that all high school students complete a semester-long course in Ethnic Studies. Regrettably, Ethnic Studies continues to be mostly limited to higher education and grades 9-12 in public schools despite research …

Voice Of The Inaudible: Well-Being Of Chinese American Young Adults, Chinese American Parents’ Parenting Competency, And The Correlation Of The Two, Diana Huang

Dissertations

Violence against Asian Americans since the beginning of the COVID-19 pandemic has become a national crisis in the United States. Racism against Asian Americans in the country, however, has been deep-rooted since the nineteenth century. Chinese American adolescents, who are susceptible to identity crisis as young adults and confront racial discrimination as a minority race, face distressing challenges. It is critical to inquire into their lived narratives and hear their voices. The author investigated the early life experiences of nine Chinese Americans and identified how racial identity is shaped at a young age with negative external inputs, as well as …

"A Raisin In A Box": The Experiences Of Racialized Black Males In Leadership Roles In The Non-Profit Sector In Toronto, Canada, Morris Anthony Beckford

Dissertations

Problem

The marginalization of Black and other racialized bodies (people of colour) has led to the position of a leader becoming so synonymous with Whiteness that it is normalized and naturalized; and worse, there has been limited analysis about why this is so. There is even less analysis of the experiences of the few people of colour who occupy leadership roles in organizations (Berkshire, 2008; Bradshaw et al., 2009; Mills et al., 2010; Nkomo, 2011; Ospina & Foldy, 2009). Astonishingly, organizations in diverse communities also have exiguous conversations about such salient issues like race and gender even though there is …

The Relationships Between Flow, Mathematics Self-Efficacy, And Mathematics Anxiety Among International Undergraduate Students In The United States, Samah Abduljabbar

Dissertations

Problem

A worldwide problem, math anxiety is defined as an anxious state with an unpleasant feeling of tension characterized by fear of failing to achieve mathematics targets. Psychologically, math anxiety involves anxiety, tension, discomfort, nervousness, fear, shock, and insecurity. Math anxiety has been perceived as a key influencer of reduced math achievement, and avoidance of math-related careers. On the other hand, abilities, flow, interests, and psychological conditions contribute to student mathematics success. Belief in one's ability to perform a specific task boosts self-efficacy, which has been studied widely as a predictor of student academic performance. When students are interested in, …

Religiosity, Family Sexual Communication & Gender As Predictors Of Attitudes Toward Oral Sex Among College/University Students In The United States, Antoinette Napier

Dissertations

Purpose

The purpose of this study was to investigate whether religiosity, family sexual communication and gender were predictors of attitudes toward oral sex among college/university students in the United States.

Method

Participants completed several surveys, which measured participants' personal religiosity, family sexual communication, and attitudes toward oral sex. A path analysis model was used to analyze the relationship between the proposed variables.

Results

The path analysis hypothesized model resulted in a poor fit for the data. The model was respecified by removing three items which showed weak beta weights. The respecified model produced a good fit for the data. The …

Teaching Shante Curtelia Dominique Ophelia Brown Johnson : An Autoethnography Of A Black Male, Seventh-Day Adventist, Jazz Avant-Garde Artist, Michael Gayle

Dissertations

Leadership is part and parcel of societies and cultures. Leadership research can provide understanding that in turn provides knowledge, resources and growth opportunities for leaders. Leadership may be understood from a personal perspective as being bound up with identity. As I examine myself as a person and as a leader, I realize that several identities are prominent: Black male identity, Christian identity, jazz avant-garde artistic identity. Each of those identities have features that contribute to leadership.

The purpose of this study is to describe and explore leadership experiences of a Black male, from the Seventh-day Adventist Christian tradition who is …

Toward A Biblical And Missiological Framework For Transformational Advocacy In The Seventh-Day Adventist Church, Michelet William

Dissertations

Problem

Adventists have been inconsistent in dealing with inequality and injustice in society, swaying between silence, accommodation, positional statements, and direct advocacy approaches. Although advocacy has become more prominent among Adventist thinkers since the end of the twentieth century, there is a lack of empirical data which answer questions related to contemporary Adventists' beliefs and practices in relation to advocacy in the context of mission. Concomitantly, there does not yet exist a documented or articulated Adventist missiological perspective on advocacy.

Research Questions

(1) What part, if any, has biblically-based social advocacy played in Adventist mission history? and (2) What do …

Play On; Give Me Excess Of It: Intercorporeality And Musical Definitions, Abram Basil Soucy Capone

Dissertations

Philosophy of music, especially in the 20th and 21st centuries, presides over a relatively narrow range of field-specific ontological and metaphysical questions. I claim that a focus on classical music and a reliance on analogies to the plastic arts constitutes an unhelpful (but pervasive) methodology in philosophy of music, one that stands in tension with its purported aim of accurately accounting for “the ways we talk, think, and act” in relation to music and musical works (Rohrbaugh 2003, 179). While philosophers of music explicitly aim to describe praxis, a significant gap exists between existing theory and ordinary musical experiences. To …

Simulation Psychological Safety Ecosystem: A Grounded Theory Study Of Nurses’ Experience With Psychological Safety In Prelicensure Simulation, Susan Eller

Dissertations

Over the past couple of decades, the utilization of simulation-based education in prelicensure nursing expanded in both frequency and functionality. Learning through simulation requires psychological safety where participants feel comfortable engaging to their fullest extent and can speak up or ask questions without fear of embarrassment to themselves or others. Professional simulation organizations provide recommendations for creating psychological safety, yet anecdotal stories from nurses report variability in their experiences ranging from positive to negative. Research regarding psychological safety in nursing education revealed some consistent themes of anxiety due to being observed or unfamiliar with simulation environments or expectations. The evolving …

Dungeons & Dragons & Dewey: Toward A Ludic Pedagogy Of Democratic Civic Life Through The Philosophy Of John Dewey And Tabletop Role-Playing Games, Susan Haarman

Dissertations

In this dissertation, which uses philosophical inquiry, I posit that tabletop role-playing games (RPGs) can provide an educative experience for democratic civic life in the Deweyan tradition. Tabletop RPGs present an invaluable resource for ongoing civic formation by encouraging deliberation and consensus building across shared goals and circumstances. Philosopher John Dewey emphasized that democracy is defined by the civic habits and collective action, not formal governance structures. The experience of playing tabletop RPGs can cultivate habitus and space for future and current citizens to practice democratic skills and commitments. Therefore, these games are a means that align with the ends …

Artapanus And Greek Colonial Poetics, Scott Harris

Dissertations

The fragments of Artapanus have proven to be enigmatic for most scholars over the years and as such have not been treated in significant detail. Most scholarship has been restricted to two separate lines of enquiry: genre and ethnicity. I suggest that the resonance between Greek colonial poetics sheds new light on Artapanus's literary agenda: namely, that Artapanus is constructing and representing the memory of Jewish cultural and political foundations using broader Greek poetics which were used to describe the civic, cultic and geographic foundation of a colony. In this way, Artapanus is no longer an outlier within the Hellenistic …

Key Stakeholders' Perceptions Of Stem Education In Zambia: A Mixed Methods Inquiry, Choobe M. Maambo

Dissertations

In the recent past, the concept of STEM education has become a “buzz phrase” in the Zambian education system, and yet, very little is known about STEM education let alone what those involved in STEM think or know about STEM in the country. The primary purpose of this study was to investigate key STEM stakeholders’ perceptions of STEM education in Zambia. To better understand STEM in the country, it was critical to explore the perceptions of STEM held by STEM teachers, STEM administrators, and STEM policymakers in the perception domains of STEM vision, STEM definition, STEM purpose, STEM relevance, and …

Past And Progress: Producing History At Chicago's 1933-34 World's Fair, Cate Liabraaten

Dissertations

During the country’s worst economic crisis, the Great Depression, Chicago hosted an event that presented a vision for the future. The 1933-34 Century of Progress Exposition was Chicago’s second world’s fair, important for revitalizing the local economy as well as encouraging optimism for a better future. While the fair’s theme officially focused on scientific and technological progress and was intended to be forward-looking, several exhibits dwelt on the past.

Study of these historic-themed exhibits reveals that by featuring Abraham Lincoln, Fort Dearborn, Jean Baptiste Point Du Sable, and a replica colonial village, Americans looked to their shared past to make …

Higher Education, Neoliberalism, And Conflict: A Case Of The University Of Balochistan In Pakistan, Syed Amir Shah

Structural Impact Of Epstein-Barr Virus- Encoded Small Rna -1 On Its Transport And Function, Zubaida Hassan

Dissertations

Epstein-Barr Virus (EBV)-Encoded RNAs (EBERs) are two small, noncoding, structurally conserved transcripts that are expressed in millions of copies in all stages of EBV infection. Despite their abundant expression, the role of EBERs in EBV biology or pathogenesis is not well defined. However, they are associated with driving cell proliferation and improving intercellular communication via their secretion in exosomes. In spite of the pathogenic potentials of EBERs, the mechanisms involved in their transport and function remain to be elucidated. The aim of this PhD dissertation was to investigate the structural impact of EBER1 in its transport and function. The conserved …
