Job Stress And Spiritual Well-Being As Correlates Of Quality Of Life Among K-12 Administrators In Seventh-Day Adventist Schools In The North American Division, John Allen Chen
Dissertations
Problem and Purpose
Research shows that K-12 administrators experience a great deal of stress. This is also true of Adventist principals (Ledesma, 2011). Some suggest improved spirituality and quality of life can alleviate or manage stress. This study examines the interrelationship between job stress, spiritual well-being, and quality of life among principals in SDA elementary and secondary schools.
Conceptual Framework and Research Design
Three major constructs guided this study: job stress, spiritual well-being, and quality of life. I theorized that higher stress would negatively correlate with quality of life and spiritual well-being. The literature shows that not all principals experience …
Understanding Secularized People Of Metro Manila: A Case Study Approach For A Contextualized Urban Ministry Strategy, Ermela T. Dizon
Understanding Secularized People Of Metro Manila: A Case Study Approach For A Contextualized Urban Ministry Strategy, Ermela T. Dizon
Dissertations
Problem
Secularization shapes people's thinking, feeling, and behaving in the cities. Yearly, there is a rise in the number of de-religionized or secularized people in cities of the world who engage in pursuits of materialism and show declining interest in religion. Sociologists and missiologists postulate about the spectrum of secularity and the variety of secularism in different context. Since Metro Manila is one of the world's top highly urbanized and densely populated cities, the Seventh-day Adventist Church encounters challenges in reaching its secularized people. It is a new turf for the church. Pastors trained for rural settings may not understand …
The Correlation Between Childhood Sexual Abuse, Intimate Partner Violence, And Sexual Revictimization On North America Emerging Adult Females' Romantic Relationship Satisfaction With Spiritual Well-Being And Post-Traumatic Growth As Mediators, Sara C. Ward
Dissertations
Problem
Emerging adulthood is a time of great adjustment, in both personal and relational terms. One of emerging adulthood's most important developmental tasks includes the excitement of intimate romantic relationships (Shulman & Connolly, 2013). These intimate romantic relationships can involve sexual as well as emotional intimacy (Fisher, 2006). When there has been sexual abuse in childhood, the perception of self and others is maladaptive and damaging, increasing one's chance of experiencing sexual revictimization and intimate partner violence (Williams et al., 2010). This can greatly influence romantic relationship satisfaction. There are very few references to strength- based trauma mediators in the …
Religiosity, Family Sexual Communication & Gender As Predictors Of Attitudes Toward Oral Sex Among College/University Students In The United States, Antoinette Napier
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 …
Predictors Of Bullying Behaviors Among Adolescents In Saudi Arabia: The Role Of Self-Esteem, Emotional Intelligence And Moral Disengagement, Ayat Hamzah
Dissertations
Problem
Bullying issues are increasing among school-age children worldwide. Children and adolescents involved in bullying as victims, perpetrators, or both are likely to experience negative consequences on their emotional, social, and academic levels (Espelage & Holt, 2001). In spite of the increasing research on bullying in Saudi Arabia, there exists gaps in the literature, especially in the role of individual traits (self-esteem, emotional intelligence) and cognitive processes (moral disengagement) on bullying behavior. Additionally, using modeling analysis to understand the predictive factors affecting bullying involvement processes also filled in some of the gaps in the literature. The current study investigated the …
An Exploration Of Factors Contributing To Service Longevity At Asia-Pacific International University, Ritha Maidom
An Exploration Of Factors Contributing To Service Longevity At Asia-Pacific International University, Ritha Maidom
Dissertations
Problem
In educational institutions of higher learning, turnover is seen as a double-edged sword that brings both benefits and problems. While turnover allows the opportunity to bring in a new employee who may be able to benefit the institution more than the one being replaced, the process of finding a replacement tends to be costly in terms of time, energy, and financial resources. As a young institution, Asia-Pacific International University (AIU) found turnovers challenging in more than one way because of its lack of stability in areas such as finance and human power. It could benefit from a clearer understanding …
Predictors Of Statistics Anxiety Among Graduate Students In Saudi Arabia, Rabab Abdulghani
Predictors Of Statistics Anxiety Among Graduate Students In Saudi Arabia, Rabab Abdulghani
Dissertations
Problem
The problem addressed in this study is the anxiety experienced by graduate students toward statistics courses, which often causes students to delay taking statistics courses until the end of their program. Students believe that statistics courses are not essential and are the greatest obstacles to obtaining their degree. Previous theoretical models have focused on predicting student performance in statistics. However, this study aims to identify specific factors that could decrease student statistics anxiety and enhance positive attitudes and self-efficacy toward statistics. The study developed a conceptual model to predict statistics anxiety among graduate students in educational and social science …
Toward A Biblical And Missiological Framework For Transformational Advocacy In The Seventh-Day Adventist Church, Michelet William
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 …
Beyond Social Emotional Learning: Toward A Humanizing And Transformative Teacher Sel, Ash Ray Busby
Beyond Social Emotional Learning: Toward A Humanizing And Transformative Teacher Sel, Ash Ray Busby
Dissertations
The purpose of this study was to bring to life the experiences of how the development of a Social, Emotional and Cultural lens prepares teachers to meet their own social and emotional needs in the classroom and consequently be better prepared to meet their students’ social and emotional needs in ways that are culturally sustaining. This qualitative research study explored these phenomena through a series of three in-depth interviews and a classroom observation with four in-service teachers in a Northern California school district that prioritizes social emotional learning (SEL) for students and teachers. The insights from this research may inform …
Measuring The Effect Of An Intervention On Student Engagement And Reading Comprehension, Kaitlin Reichart
Measuring The Effect Of An Intervention On Student Engagement And Reading Comprehension, Kaitlin Reichart
Dissertations
Students arrive at school each day with a great disparity in emotional and learning readiness. This is caused by a multitude of factors such as chronic stress, family separation, poverty, the COVID-19 pandemic, sexism, trauma, ACEs, racism, and lack of access to resources. Students need daily assistance in understanding and regulating their emotions. Schools have become the central place for supporting students' mental health, yet teachers are generally overworked and underprepared in the area of supporting mental health. The purpose of this dissertation was to determine the impact of a universal tier one self-regulation intervention on student engagement and reading …
Play On; Give Me Excess Of It: Intercorporeality And Musical Definitions, Abram Basil Soucy Capone
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 …

Design And Synthesis Of Novel Antibiotics And Anticancer Agents Targeting Pharmaceutically Relevant Enzymes, Sebastian Flieger
Design And Synthesis Of Novel Antibiotics And Anticancer Agents Targeting Pharmaceutically Relevant Enzymes, Sebastian Flieger
Dissertations
Boron neutron capture therapy (BNCT) is a binary radiotherapeutic modality for cancer treatment, in which delivery agents containing 10B atoms are transported into tumor cells and then irradiated with low-energy thermal neutrons. Matrix metalloproteinases (MMPs) are a family of zinc-dependent endopeptidases that are involved in the remodeling and degradation of all components of the extracellular matrix (ECM). Overexpressed levels of MMP activity have been implicated in several disease states including tumor growth and metastasis. We have appended a borane-rich carborane cluster onto MMP-targeting pharmacophores to enable delivery of 10B atoms to a tumor. Herein, we describe the molecular docking experiments …
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
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 …
Comparative Analysis Of Classification Performance For U.S. College Enrollment Predictive Modeling Using Four Machine Learning Algorithms (Artificial Neural Network, Decision Tree, Support Vector Machine, Logistic Regression), Anna Kye
Dissertations
Every year, the national high school graduation rate is declining and impacting the number of students applying to colleges. Moreover, the majority of students are applying to more than one college. This makes a lot of colleges to be highly competitive in student recruitment for enrollment and thus, the necessity for institutions to anticipate uncertainties related to budgets expected from student enrollment has increased. Hence enrollment management has become a pivotal sector in higher education institutions. Data and analytics are now a crucial part of enhancing enrollment management. Through big data analytics-driven solutions, institutions expect to improve enrollment by identifying …
Key Stakeholders' Perceptions Of Stem Education In Zambia: A Mixed Methods Inquiry, Choobe M. Maambo
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 …
None Of Us Are Safe: How Leaders Sustain Culturally Responsive Elementary And Middle School Improvement Planning, Jerry B. Michel
None Of Us Are Safe: How Leaders Sustain Culturally Responsive Elementary And Middle School Improvement Planning, Jerry B. Michel
Dissertations
In the spring of 2020, school leaders, school boards, and teachers faced challenges beyond the COVID-19 pandemic in the United States, finding themselves under attack for the perceived applications of critical race theory in school curriculum. These conditions made active engagement in equity-focused school improvement planning more challenging. School leaders and leadership teams may benefit from using an established framework to identify strengths and areas for growth around culturally responsive pedagogy for effective school improvement planning. This article explores the use of Hammond’s (2015) Ready for Rigor Framework as a tool for identifying prioritizing which conditions for culturally responsive pedagogy …
Establishing A Health-Based Social Hierarchy, Akila Salaam Raoul
Establishing A Health-Based Social Hierarchy, Akila Salaam Raoul
Dissertations
Social dominance theory (SDT) proposes a basic human nature to form social hierarchies based on social group membership with dominant and subordinate social groups. These social hierarchies are maintained through legitimizing myths, or beliefs that work to frame the existing social system as fair by suggesting that individuals receive the social status they deserve based on their actions and contributions to society as opposed to their group membership. The level at which an individual wants to maintain social hierarchies is indicated by their Social Dominance Orientation (SDO). SDT has been extensively studied in the context of race, gender, and age …

Characterization Of Mroq-Dependent Regulation Of Staphylococcus Aureus Quorum Sensing, Madison Ruth Stock
Characterization Of Mroq-Dependent Regulation Of Staphylococcus Aureus Quorum Sensing, Madison Ruth Stock
Dissertations
Gram-positive bacteria produce small autoinducing peptides (AIPs), which act to regulate expression of genes that promote adaptive traits including virulence. The Gram-positive pathogen Staphylococcus aureus generates a cyclic AIP that controls expression of virulence factors via the accessory gene regulatory (Agr) system. S. aureus strains belong to one of four Agr groups (I, II, III, and IV), and each group harbors allelic variants of AgrD, the precursor of AIP. In a prior screen for S. aureus virulence factors, the Alonzo lab identified MroQ, a putative peptidase. A ΔmroQ mutant closely resembled a Δagr mutant and had significant defects in AIP …
A Portrait Of The Leadership Of Women In Early Christianity: An Archaeological Study In Light Of The Historical And Socio-Cultural Contexts, Carina Prestes
A Portrait Of The Leadership Of Women In Early Christianity: An Archaeological Study In Light Of The Historical And Socio-Cultural Contexts, Carina Prestes
Dissertations
Problem
The participation of women in the Early Christian communities is widely accepted. Nevertheless, there is no consensus on what was their role in these communities. Until now the study of women in the Early Christian communities has focused mostly in the writings of some ancient authors and a few biblical texts. These studies have been done mostly by theologians and historians. Such studies rarely take a deep look at the Greco-Roman background and at the historical, socio-cultural contexts. This contextualization can be quite fruitful and should be informed by recent archaeological discoveries of the first centuries of Christianity. Thus, …
A Comparison Of Virtual Vs. Traditional Cycling Exercise On Perceived Duration And Exercise Enjoyment, Kyle W. Reason
A Comparison Of Virtual Vs. Traditional Cycling Exercise On Perceived Duration And Exercise Enjoyment, Kyle W. Reason
Dissertations
We compared perceived duration, ratings of enjoyment and RPE between virtual vs. standard cycling. Participants completed a VO2 peak test and four counterbalanced trials (two 20-min, two 40-min) one at each duration on the interactive Expresso bike (EXP) and a workload matched trial on a Velotron (VEL). Acute RPE were assessed every 5-min. Perceived duration (min) and exercise enjoyment were assessed 15-min post. No significant differences were found for perceived duration between trials (SDE 23.9 ± 8.4; SDV 27.1 ± 9.6; LDE 40.0 ± 12.1; LDV 38.9 ± 10.8). For long duration expresso (LDE) RPE-overall were significantly lower at 25, …
Structural Impact Of Epstein-Barr Virus- Encoded Small Rna -1 On Its Transport And Function, Zubaida Hassan
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 …
Using Materialized Views For Answering Graph Pattern Queries, Michael Lan
Using Materialized Views For Answering Graph Pattern Queries, Michael Lan
Dissertations
Discovering patterns in graphs by evaluating graph pattern queries involving direct (edge-to-edge mapping) and reachability (edge-to-path mapping) relationships under homomorphisms on data graphs has been extensively studied. Previous studies have aimed to reduce the evaluation time of graph pattern queries due to the potentially numerous matches on large data graphs.
In this work, the concept of the summary graph is developed to improve the evaluation of tree pattern queries and graph pattern queries. The summary graph first filters out candidate matches which violate certain reachability constraints, and then finds local matches of query edges. This reduces redundancy in the representation …

Carrier Transport Engineering In Wide Bandgap Semiconductors For Photonic And Memory Device Applications, Ravi Teja Velpula
Carrier Transport Engineering In Wide Bandgap Semiconductors For Photonic And Memory Device Applications, Ravi Teja Velpula
Dissertations
Wide bandgap (WBG) semiconductors play a crucial role in the current solid-state lighting technology. The AlGaN compound semiconductor is widely used for ultraviolet (UV) light-emitting diodes (LEDs), however, the efficiency of these LEDs is largely in a single-digit percentage range due to several factors. Until recently, AlInN alloy has been relatively unexplored, though it holds potential for light-emitters operating in the visible and UV regions. In this dissertation, the first axial AlInN core-shell nanowire UV LEDs operating in the UV-A and UV-B regions with an internal quantum efficiency (IQE) of 52% are demonstrated. Moreover, the light extraction efficiency of this …
