Whether studying physical sciences, social sciences, engineering, mathematics, humanities, or education, approximately one in every two doctoral students fail to persist to degree completion (Bowen & Rudenstine, 1992; Lovitts, 2001; Tinto, 2012). A quantitative comparative study focused on two populations; students currently enrolled in the professional doctorate EdD program and former EdD students, including students who started but did not finish the program. Research-based variables, characterized as personal and program factors driving doctoral student attrition, were tested for significance. The participation criteria defined at least 80% of the program’s course content in totality was or is currently delivered online from …

Older Hispanic Women With Health Care Provider Diagnosed Osteoarthritis: Experience And Perceptions Of Culturally Competent Care, Claudia A. Oglivie

Dissertations

Arthritis is the leading cause of disability among U.S. adults over the age of 65. Osteoarthritis, the most common form of arthritis, has an incidence rate that increases with age with the highest rates among women. Hispanic women are more affected than any other racial or ethnic group. Little is known about how Hispanic women respond to having osteoarthritis and how they manage its symptoms and limitations. Few studies have examined the specific experiences and perceptions of this population. We do not know how differences in incidence, access to care, disease burden, and activity limitations affect the treatment of Hispanic …

Perceptions Of Community Of Associate Degree Nurse Learners In An Rn-To-Bsn Online Program, Cherie R. Rebar

Dissertations

Registered Nurses (RNs), when educated in an Associate Degree (AD) program, learn in a face-to-face environment. Today's preferred standard of education for RNs is to achieve a minimum of a Bachelor's degree. For convenience while they continue working, numerous AD-prepared nurses seek online education to complete their Bachelor of Science in Nursing (BSN) degree, yet have never studied in this type of learning environment, nor have they learned to forge educational relationships in a virtual setting. At the time that this study was proposed, limited research existed that studied how BSN students perceive this forum, and how it affects their …

Comparing The Effects Of Two Debriefing Frameworks; Promoting Excellence And Reflective Learning In Simulation (Pearls) Framework And Structured And Supported Debriefing Model (Gas) Framework, Krista M. Prendergast

Dissertations

Essential learning occurs during the debriefing phase of simulation-based learning experiences. Despite this knowledge, evidence regarding the most effective debriefing method is insufficient. The primary purpose of this study was to compare the effectiveness of two debriefing frameworks, Promoting Excellence and Reflective Learning in Simulation (PEARLS) and Structured and Supported Debriefing Model using Gather, Analyze, Summarize (GAS) on student performance during simulation. This pilot study used a two group, pretest-posttest, experimental design with group randomization.

Adoptive Parents' Lived Experience Of Bonding With Their Adopted Infants: A Phenomenological Study, Sharon M. Bator

Dissertations

Nurses' roles facilitating bonding between adoptive parents and their infants have been premised on the idea that the experience is the same as for biological parents. Developmental theorists Bowlby (1969) and Erikson (1959) maintained that bonding between an adoptive parent and their adopted child is essential for normal growth and development. The purpose of this study was to study the experience of bonding between adoptive parents and children.

More Than Midnight Feasts?: A Gastrocritical Reading Of Enid Blyton’S Malory Towers, St. Clare’S And The Naughtiest Girl In The School Series, Rebecca Broomfield

Dissertations

Food is fundamental to life. It is also fundamental to culture; through our production, manipulation and consumption of foodstuffs, the way in which we eat has amassed a range of rituals and rules. This suggests that food can be used to indicate more than mere biological need. Food and foodways are a common occurrence throughout literature, not least children’s literature. This thesis applies gastrocriticism as a paradigm to investigate the use of food and foodways in Enid Blyton’s Malory Towers, St. Clare’s and The Naughtiest Girl school series. Gastrocriticism is an emerging form of literary criticism that considers the complex …

Schooled To The Streets? Exploring The Relationship Between K-12 Educational Experiences And Early Careers In Activism, David Abraham Castro

Dissertations

Since the late eighteenth century, organizing and activism have been part of the urban landscape, from the labor organizing of Eugene Debs in the early twentieth century to the community organizing work of Saul Alinsky during the 1950s and 1960s. The development of community organizers is strongly tied to local institutions such as factories, houses of worship, and schools. For many youths in Chicago, schools often become the sites of political and social awakening and lead to activism beyond the schoolhouse. Within the current context of urban education scholars, practitioners, policymakers, and community organizers alike agree that the perspectives of …

Investigating The Bactericidal Activity Of Lactobacillus Crispatus Cell-Free-Supernatant, Omar Majed Abdul-Rahim

Dissertations

Antimicrobial-resistant (AMR) microorganisms are an increasingly seriousproblem worldwide, accounting for thousands of fatalities annually. The current literature on combating AMR pathogens often centers on commensal microbes such as Lactobacillus species, which are most frequently found in asymptomatic ‘healthy’ patients and are believed to elicit protective effects. In this dissertation, I sought to investigate the protective effect of Lactobacillus crispatus, utilizing our vast collection of clinical isolates. Previous work from our lab had found that cell-free-supernatant (CFS) of L. crispatus is robustly bactericidal, and that this killing activity does not depend on hydrogen peroxide or lactic acid. We identified phenyl-lactic acid …

Broaching The Topics Of Religion And Spirituality In Therapy: Considering The Influence Of Therapist Competence And Organizational Competence, Papa N. Adams

Dissertations

Many individuals have identified religion and/or spirituality (R/S) as integral in the construction of their worldview and important in mental health. Research has demonstrated that clinicians hold positive attitudes towards integrating R/S into therapy yet reported low levels of actually integrating R/S into therapy sessions. This study examined therapist behavior in regard to broaching discussions about R/S in psychotherapy sessions. This study proposed that clinician broaching behavior would be correlated with the clinician’s R/S competence. Furthermore, the relationship between broaching and clinician’s competence would be moderated by the R/S competence of the clinician’s environment (defined as the organizational/institutional R/S competence). …

School Leaders’ Assessment Of Teachers’ Preparedness For Culturally Responsive Teaching, Victoria Maria Siliunas

Dissertations

Societal and school inequities continue to be highlighted via widening achievement gaps that adversely impact historically marginalized groups of students and their communities. An acknowledgement of the importance of developing teachers who are prepared to work with students of culturally differing identities from their own in the day-to-day work of teaching has inspired a shift in language and practice from a more general multicultural approach to a culturally responsive teaching methodology in which a purposeful inclusion of the ethnic and cultural backgrounds of students is prioritized. Addressing challenges schools face related to cultural difference between teachers and the students they …

To examine leadership in Adventist colleges, I used the online MLQ-5X short form. I secured participation from 12 colleges and after repeated emails secured 168 responses. I analyzed the relationship between leadership styles, several leader characteristics and leader effectiveness, using SEM, …

"The Best Man That Ever Trod Shoe Leather" And His "Crown Of Rejoicing" : The Personal Relationship Of James And Ellen White, 1845-1881, Gerson Cardoso Rodrigues

Dissertations

James White (1821-1881) and Ellen G. White (1827-1915), co-founders (with Joseph Bates) of the Seventh-day Adventist denomination, were united in marriage on August 30, 1846, and lived together for thirty-five years until James died. As leaders (though Ellen White never assumed any administrative post) of the emerging denomination and putting all effort for the growth and mission of the Adventist cause, the Whites lived an intense life of writing, publishing, preaching, and traveling. Though their marriage was a blessing for both of them, the intensity of their lives, health issues, and their humanity, caused marital difficulties in some periods of …

Racial Identity, Hair Esteem, Hair Texture, And Hairstyle Choice As Correlates Of Psychological Well-Being Among Afro-Latinas In The United States, Marielsy Esther Pimentel

Dissertations

Problem

During the Colonial period, hair was one of the designated phenotypic markers of racial group membership used to assign or deny privilege. Privileges are still assigned to people based on their racial group membership and their proximity to Whiteness. As such, Hair remains a salient part of Afro-Latina women’s lives and identities, with its influences seen in the personal, social, and mental realms. How an Afro-Latina wears her hair can have legal, social, and intrapersonal consequences. The subsequent treatment of Afro-Latinas because of their hairstyle can affect how they view themselves and even how they relate to others, especially …

Self-Efficacy And Job Satisfaction As Predictors Of Burnout Among School Psychologists In The Midwest United States, Elizabeth Mcknight-Romney

Dissertations

Problem

The concept of burnout is expressed as a syndrome evidenced by chronic exhaustion, depersonalization, and a lack of personal accomplishment. Burnout or work burnout syndrome is conceptualized as a prolonged process of emotional fatigue, involving loss of motivation and expectations, generating a feeling of failure affecting personal, work, and social levels (Maslach et al., 2001). Victims of burnout usually become exhausted, cynical about work-related matters, and question their capacity or ability to perform. Job burnout includes feeling exhausted physically, emotionally, and or mentally in the context of work (Maslach & Jackson, 1981). The demanding profession of school psychology has …

Basic Psychological Needs Satisfaction, Autonomy Support, And Mindsets As Predictors Of Self-Regulation In University Online Learners, Ting Jin

Dissertations

Problem

In contrast to more traditional learning environments, it can be difficult to "see and hear" both the instructor and, more crucially, the students when engaging in online education. This has been one of the most common criticisms leveled against online education for a long time. The COVID-19 disruption and transformation of online learning in higher education underlines the fact that variance among online learners in terms of academic success and psychological well-being are determined by the level and quality of self-regulation. What is the degree of self-regulation among American university students who study online because of the COVID-19 pandemic's …

A qualitative research case study methodology is the research design used, which, with my research questions, I considered would best uncover knowledge and provide perspectives that would provide an increased understanding of the issues arising from the …

An Investigation Of The Relationship Between Subjective Mental Workload And Objective Indicators Of User Activity, Greg Byrne

Dissertations

Whilst the concept of physical workload is intuitively understood and readily applicable in system design, the same cannot be said of mental workload (MWL), despite its importance in our increasingly technological society. Despite its origin in the mid 20th century, the very concept of ”mental workload” is still a topic of debate in the literature, although it can be loosely defined as “the amount of mental work necessary for a person to complete a task” (Miller, 1956; Longo, 2014). Several methods have been utilized to measure of MWL, including physiological methods such as neuro-imagery, performance-based metrics, and subjective measures via …

Evaluating The Performance Impact Of Fine-Tuning Optimization Strategies On Pre-Trained Distilbert Models Towards Hate Speech Detection In Social Media, Aidan Mcgovern

Dissertations

Hate speech can be defined as forms of expression that incite hatred or encourage violence towards a person or group based on race, religion, gender, or sexual orientation. Hate speech has gravitated towards social media as its primary platform, and its propagation represents profound risks to both the mental well-being and physical safety of targeted groups. Countermeasures to moderate hate speech face challenges due to the volumes of data generated in social media, leading companies, and the research community to evaluate methods to automate its detection. The emergence of BERT and other pre-trained transformer-based models for transfer learning in the …

Exploring The Utility Of Geostationary Satellite Observations In Air Quality Studies, Peiyang Cheng

Dissertations

The air quality community uses numerical models for air quality forecasting and establishing regulatory policies. However, the prediction of clouds and the estimation of emissions remain highly uncertain, limiting the credibility and usefulness of model results. This study explored how Geostationary Operational Environmental Satellite (GOES) observations can be used to reduce the uncertainty in air quality simulations. The major findings are summarized as follows. First, assimilating the GOES-13 cloud products into a numerical weather prediction model improved the agreement between model-predicted and satellite-observed clouds by 3.5%. Model surface insolation bias and error were reduced by 7.1 W m^–2 (13.1%) …

Nanomaterials In Theranostics : Therapeutics And Diagnosis Against Infectious Diseases, Unnatiben S. Patel

Dissertations

Nanomaterials-based hybrid nano therapy is gaining attraction as a promising way to treat intracellular bacterial infections. Gold-based nanomaterials have been widely used for biomedical applications such as photothermal therapy (PTT). This thesis discusses the development of a combination therapeutic approach that kills intracellular bacteria in conjunction with photothermal and antibiotic therapy using gold nanorod (GNR) based nano-assembly. This NIR laser-activated nano-assembly delivers antibiotics to the site of infection and offers PTT. The synergistic application of both therapies increases the efficacy of treatment. The protected delivery of antibiotics and their release in the proximity of the bacterial surface decreases off-target toxicity …

Accuracy Improvement Of Dynamic Sensors Measured Input Reconstruction Using Sliding Mode Observers, Rajesh Rayala Jayasheelareddy

Dissertations

Sensor dynamics adversely affect the accuracy of the obtained measurement by dynamically distorting the true value. The accuracy of the measurement may be further degraded by noise/exogenous perturbations. A sensor’s accuracy and performance are improved by reconstructing the true input signal of the sensor from the distorted measurement polluted by a corruption signal or exogenous inputs using Sliding mode and Higher-order sliding mode observer (SMO/HOSMO). The proposed technique is used to reconstruct/estimate a sensor’s true signal, thereby improving the transient response and driving the estimation steady state error to zero in finite time. The proposed SMO algorithm is based on …

Modeling A Power-Generating Pulsed Nuclear Magnetic Nozzle, Nathan Schilling

Dissertations

Pulsed nuclear (fusion, fission, and fission/fusion hybrid) propulsion systems provide the potential for 10,000 s specific impulse and specific powers of 1000 W of jet power per kg of propulsion system mass. This enables a new class of medium thrust, high specific impulse capability, resulting in 1/3 of the trip times and significantly higher payload mass fractions compared with chemical propulsion performing the same mission. One of the challenges for pulsed nuclear propulsion is the conversion of an isotropic explosion to directed thrust, another challenge is the generation of electrical power needed to run these systems. To meet both of …
