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 …

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 …
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
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 …

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 …
Elucidating The Role Of A Staphylococcal Glucosaminidase In Host Innate Immune Responses, Zachary Resko
Elucidating The Role Of A Staphylococcal Glucosaminidase In Host Innate Immune Responses, Zachary Resko
Dissertations
The peptidoglycan of Staphylococcus aureus is a critical cell envelope constituent and virulence factor that subverts host immune defenses and provides protection against environmental stressors. Peptidoglycan chains of the S. aureus cell wall are processed to characteristically short lengths by the glucosaminidase, SagB. It is well established that peptidoglycan is an important pathogen-associated molecular pattern (PAMP) that is recognized by the host innate immune system and promotes production of pro-inflammatory cytokines, including IL-1β. However, how bacterial processing of peptidoglycan drives IL-1β production is comparatively unexplored. Here, we tested the involvement of staphylococcal glucosaminidases in shaping innate immune responses and identified …
Identification Of Conditions That Promote Biofilm Formation By Vibrio Fischeri And Elucidation Of The Underlying Signal Transduction Pathway, Courtney Noelle Dial
Identification Of Conditions That Promote Biofilm Formation By Vibrio Fischeri And Elucidation Of The Underlying Signal Transduction Pathway, Courtney Noelle Dial
Dissertations
Biofilms are communities of microorganisms that have intrinsically antimicrobial properties and are difficult to treat in the clinical setting. The marine bacterium Vibrio fischeri efficiently colonizes its symbiotic squid host, Euprymna scolopes, by producing a transient biofilm dependent on the symbiosis polysaccharide (SYP), making it the perfect model system to study biofilm dynamics. In vitro, however, wild-type (WT) strain ES114 fails to form SYP – dependent biofilms. Instead, genetically engineered strains, such as those lacking the negative regulator BinK, have been developed to study SYP biofilms. Historically, V. fischeri has been grown using LBS, a complex medium containing tryptone and …
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 …

Dynamic Control Of The Cardiac Calcium Pump, Sean Robert Cleary
Dynamic Control Of The Cardiac Calcium Pump, Sean Robert Cleary
Dissertations
The sarco/endoplasmic reticulum Ca2+-ATPase (SERCA) sequesters Ca2+ into the endoplasmic reticulum of cells to establish a reservoir for Ca2+ signaling. In the heart, the activity of this transporter is tightly controlled via direct interactions with two competing regulatory micropeptides: phospholamban (PLB) and dwarf open reading frame (DWORF). PLB inhibits SERCA, while DWORF activates SERCA. These competing interactions determine cardiac performance by modulating the Ca2+ signals that drive the contraction/relaxation cycle. Previous studies indicated these SERCA-micropeptide interactions are Ca2+-sensitive; SERCA binds PLB more avidly at low cytoplasmic [Ca2+] but binds DWORF better when [Ca2+] is high. Here, FRET-microscopy demonstrated that this …

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 …
Ethnic-Racial Socialization Practices Of Dominican Mothers With Their Young Children: Understanding Practices With A Sociohistorical Context Framework, Sabrina Altagracia Mendez-Escobar
Ethnic-Racial Socialization Practices Of Dominican Mothers With Their Young Children: Understanding Practices With A Sociohistorical Context Framework, Sabrina Altagracia Mendez-Escobar
Dissertations
Parents who self-identify as members of a community of color engage in practices aimed at teaching their children what it means to be a member of their ethnic-racial group which are called ethnic-racial socialization (ERS) practices. Promoting a positive sense of ethnic-racial identity through ERS contributes to balancing the negative effects of discrimination which can be helpful to children who are part of a marginalized group in the US including Latinx children. However, when the family practices of Latinx families are explored in the literature, various Latinx groups are lumped together. When studying ERS, research should aim to consider Latinx …
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 …

Improving The Stimulation Selectivity In The Human Cochlea By Strategic Selection Of The Current Return Electrode, Ozan Cakmak
Dissertations
The hearing quality provided by cochlear implants are poorly predicted by computer simulations. A realistic cochlear anatomy is crucial for the accuracy of predictions. In this study, the standard multipolar stimulation paradigms are revisited and Rattay’s Activating Function is evaluated in a finite element model of a realistic cochlear geometry that is based on µ-CT images and a commercial lead. The stimulation thresholds across the cochlear fibers were investigated for monopolar, bipolar, tripolar, and a novel (distant) bipolar electrode configuration using an active compartmental nerve model based on Schwartz-Eikhof-Frijns membrane dynamics. The results suggest that skipping of the stimulation point …

Interactions Of Amyloid Peptides With Lipid Membranes, Yanxing Yang
Interactions Of Amyloid Peptides With Lipid Membranes, Yanxing Yang
Dissertations
The aggregation of amyloid proteins into fibrils is a hallmark of several diseases including Alzheimer’s (AD), Parkinson’s, and Type II diabetes. This aggregation process involves the formation of small size oligomers preceding the formation of insoluble fibrils. Recent studies have shown that these oligomers are more likely to be responsible for cell toxicity than fibrils. A possible mechanism of toxicity involves the interaction of oligomers with the cell membrane compromising its integrity. In particular, oligomers may form pore-like structures in the cell membrane affecting its permeability or they may induce lipid loss via a detergent-like effect. This dissertation aims to …
Combustion Soot Nanoparticles: Mechanism Of Restructuring And Mechanical Properties, Ali Hasani
Combustion Soot Nanoparticles: Mechanism Of Restructuring And Mechanical Properties, Ali Hasani
Dissertations
Soot, a product of incomplete combustion of fossil fuels, is a global warming agent. The effect of soot particles on climate depends on their morphology. Freshly released soot particles are fractal lacey aggregates, but they often appear collapsed in atmospheric samples collected away from emission sources. A body of work has concluded that the collapse is caused by liquid shells when they form by vapor condensation around soot aggregates. However, some recent studies argue that soot remains fractal even when engulfed by the shells, collapsing only when the shells evaporate. To reconcile this disagreement, the effects of the condensation and …
