A Reassessment Of The Excavations At Tall Safut, Owen D. Chesnut

Dissertations

Problem

The site of Tall Safut in Jordan was excavated under the direction of Donald Wimmer during the years of 1982-2001. Other than the preliminary reports and encyclopedia articles published by Wimmer, no detailed analysis of the remains and no final reports have been published since the conclusion of excavations in 2001. The site has received only brief mention in other articles and books dealing with archaeology because of its remains dating to the Middle Bronze Age, Late Bronze Age, and Iron Age. However, there is a significant gap in the scholarly understanding of the history of the northern hill …

Dissertations

Problem and Purpose

Much research has been done in past years on the topic of student achievement, with most of those studies focusing on factors that contribute to student achievement. Little, or no research has been done, especially in the country of Zambia, that has focused on the relationship between leadership style, teacher self-efficacy, and the extent to which these constructs impact student achievement. This study explored the school principals' leadership style, teacher self-efficacy, and the extent to which these factors contribute to student achievement in Chikankata District, Zambia. The Ministry of Education in Zambia and other educators, especially those …

Advising Assessment Practices Of Advising Professionals At An Accredited United Kingdom Urban Career-Focused Higher Education Institution: A Replicated Quantitative, Descriptive Analysis, Catherine E. Mahrt-Washington

Dissertations

The Problem

As the world has flattened, the globalization and quality education movement surrounding higher education worldwide has led to the accountability of all stakeholders regarding student success in and beyond the classroom. Student mobility continues to impact tertiary enrollments as families and students consider the proliferated traditional and non-traditional enrollment alternatives along with prospective lower tertiary debt options. Although assessment, an accountability tool, in co-curricular areas such as advising has been overlooked by leaders, advising is not impervious to accountability consequences. The problem is that assessment of advising, if performed, is oftentimes implemented informally, without a well-defined framework or …

Journey With Autism: Successful Educational And Social Interventions From A Single Case Study, Kwame M. De Jonge-Moore

Dissertations

Problem

Statistics indicate that Autism Spectrum Disorder (ASD) is on the increase in America and worldwide (Xu, Strathearn, Liu, & Bao, 2018; Baio et al., 2018). Autism spectrum disorder can impair an individual’s ability to engage in neurotypical behavior, which has the potential to increase their vulnerability to being shunned and bullied. This makes autism a major societal concern with significant costs to the individual, their family, private/public health insurance, state financial aid programs, and to the nation. This present study was undertaken to determine, in the opinions of those connected to the case, whether the interventions engaged in this …

The Relationship Between Combat Experience, Veteran Pathology And The Pathology Of Their Intimate Partners: What Factors Predict The Pathology Of Veterans And Their Intimate Partners, Edwin A. Brennan

Dissertations

Problem Statement

Military members and their family members who are part of the Global War on Terrorism have experienced deployments and war for over sixteen years and with the resulting toll on both the veteran and their intimate partner. As a result, higher levels of pathology, such as PTSD, Anxiety, and Depression have been experienced by this population. While research has studied the effect of combat on military members, very little research has addressed the effects on family members. Further, no research that has been found by this researcher, has addressed the concept of resonating of pathology between the combat …

Archaeological Backgrounds Of The Sanctuary: A Search For Egyptian Cultural Influence In The Construction Of The Hebrew Tent-Sanctuary, Leslie Scott Baker Jr

Dissertations

Problem

Although the documented description of the construction of the tent-sanctuary appears to give it an Egyptian context in terms of the materials used and the culture of the artisans, in three distinct spheres (sacred, royal-domestic, and military), very little work has been done in comparing the descriptions in the text with the recovered archaeological fabric from Egypt and no study has, as yet, taken the next step of quantifying that comparison through a potentially-repeatable statistical analysis in an effort to determine, in an unbiased manner, the nature of the relationship.

Method

Design and frequency data of the appearing materials …

The Interplay Of Racial Identity Attitude And Religious Orientation On The Social Integration Experiences Of Black African College Students And African American College Students Attending Predominantly White Institutions In The United States, Christina Miattamengie Johnson

Dissertations

Problem

Not much attention has been devoted to the academic experiences of Black African college students, the latter being typically categorized with those of African Americans (Kim, 2014). While research has effectively documented the social challenges that African American college students experience at (Predominantly White Institutions (PWI). much less research has been conducted on the social experiences of subcategories within the Black population, specifically, Black Africans. Though researchers have speculated on the potential differences between the social integration experiences of Black Africans and African American college students as these relate to religious orientation and racial identity attitude, no empirical studies …

Working Memory And Attention As Predictors Of Processing Speed In Elementary School Students: A Developmental Study, Monih Alshehri

Dissertations

Problem

Many studies suggest that Processing Speed (PS), Attention, and Working Memory (WM) are major cognitive functions that collaborate to achieve a coherent cognitive system. The aim of the current study was to improve the conception of how these cognitive functions interrelate. The study addressed two main questions: the first, whether PS can be predicted by WM (visual, verbal, and the central executive) and attention of elementary students in first and fifth grade; the second, whether there are gender differences in the rate of change in WM and PS from first to fifth grade.

Method

The participants were taken from …

Collective Responsibility By Agreement, David Atenasio

Dissertations

It is often challenging to fairly distribute responsibility for harms that result from collective wrongdoing. Few object to blaming an agent for making a contribution to wrongdoing, but it is far more controversial to attribute fault to one agent for the contributions made by other participants in collective wrongdoing. I argue that we ought to distribute co-responsibility for collective wrongdoing only to those who authorize the offending actions, whether expressly or tacitly. By authorizing another to carry out wrongdoing on one's behalf, one becomes to blame for the unjustified harm caused by one's agent or agents. In this dissertation, I …

Women's Decision-Making For Subsequent Pregnancy After A Cesarean Delivery, Melinda Dixon

Dissertations

The purpose of this study is to generate a theory of the decision making process for women as they choose a birth option after a previous Cesarean delivery. The research method of choice when little is known about the phenomena is qualitative research. A qualitative approach was used to generate a substantive theory of decision making for women deciding subsequent pregnancy birth mode after a previous Cesarean delivery. The classical grounded theory methodology including sampling plan, recruitment, data collection and analysis outlined in Glaser and Strauss (1967) guided this study. Twelve study participants with a history of one previous Cesarean …

Latina College Student Leadership Development At A Historically White College/University, Kristina Garcia

Dissertations

This dissertation study contributes to the dearth of research examining the leadership development of Latina college students. Using critical race feminism (CRF) as a guiding framework, this study centers the experiences of Latina college students, exploring how dominant cultural values, Latinx cultural values, and the context of the collegiate environment influence how this population experiences leadership development. Utilizing a qualitative research design, participants shared stories and insights related to how they conceptualized and experienced leadership development in the context of a historically White college/university. The data indicates that Latina college students experience leadership as a constant negotiation of dominant cultural …

Teacher Preparation And English Language Learners: The Negotiation Of Teaching Identities In Communities Of Practice, Eleni Giatsou

Dissertations

This dissertation unveils the identity formation and negotiation processes of teacher candidates, through their practice with English Language Learners (ELLs) in a field-based teacher preparation program. Identity, like learning, is socially constructed and continuously negotiated by someone's engagement in a community (Wenger, 1998). Thus, sociocultural theory and specifically the theoretical construct of communities of practice (Wenger, 1998), guided the exploration of candidates' teaching identities to reveal the processes of becoming a teacher of ELLs. I conducted a qualitative case study to examine candidates' teaching practices with ELLs at a surface level and the (re)construction of their teaching identities at a …

Membrane Microdomains As Platforms For Extra-Cellular Fusions, Michael Hantak

Dissertations

Life requires biological membranes. Membrane-enclosed compartments separate and unite through dynamic fission and fusion reactions. These are catalyzed processes that are central in organismal biogenesis. This dissertation focuses on extracellular membrane fusions, which are central to several processes. (1) Enveloped viruses enter cells through membrane fusions. (2) Extracellular vesicles (EVs) also deliver molecules into cells through membrane fusions. (3) Entire cells also fuse together, generating fertilized zygotes, skeletal muscles, and giant cell macrophages.Mechanisms of extracellular membrane fusion are poorly understood. This dissertation aimed to further define these mechanisms. We focused on regulatory cofactors, including tetraspanins, transmembrane proteins that cluster into …

Determination Of Transforming Growth Factor-Β Signaling Targets In Activated T Cells, Ramiah Jacks

Dissertations

T lymphocytes are a critical component of the adaptive immune system and their responses in pathogenic and steady state conditions require strict regulation. One mechanism involved in this regulation is Transforming Growth Factor-β (TGF-β) signaling. TGF-β can act on activated T cells to facilitate the differentiation of TGF-β dependent T helper subsets or the suppression of T cell activation and proliferation. However, the molecular mechanism(s) by which TGF-β signaling controls T cell differentiation vs T cell suppression remain poorly understood.TGF-β signaling is propagated by initially binding to the TGF-β type II receptor, which subsequently activates TGF-β type I receptor (TGF-βRI) …

The Effectiveness Of An Ambulatory Care Health System Redesign On Patient Engagement, Healthcare Utilization, And Clinical Indicators, Nancy Johansen Madsen

Dissertations

Diabetes is a lifelong debilitating and deadly chronic disease affecting nearly one out of every eleven Americans. This public health problem costs $245 billion annually in the United States. Long term research trials have shown that diabetes complications can be prevented with good glycemic control, but it is difficult for patients to maintain control without much support from their healthcare team. U.S. healthcare remains fragmented. With the passage of the Affordable Care Act, there are opportunities to redesign health care delivery to minimize fragmentation and improve patient outcomes. The aim of this study is to determine if a redesigned care …

Predicting Decision-Making In Relation To Health-Risk Behavior In College Freshmen, Anne Bijumon Luckose

Dissertations

Method/Measurements: A cross-sectional correlational design explored the relationships between decision-making, health-risk behaviors and social support systems in college freshmen. The aims of the study were: 1) to explore the relationship between decision-making and health-risk behaviors among college freshmen; 2) to determine whether or not family support and social support jointly predict decision-making among college freshmen; and 3) to ascertain whether or not the effect of family support on decision-making is different for male and female college freshmen. Measurement was collected at one time-point and participants in this study completed on-line questionnaires through a web-based online survey software application with measures …

The Social And Contextual Mechanisms Of Children's Learning In Museums, Lindsay R. Maldonado

Dissertations

This study explored the associations between immersive exhibit design, mother-child engagement, conversational interactions, and children's learning. Participants were 41 mothers and their 6-8-year-old children (Mage=7.15, SD=.79). A within-subjects, mixed methods approach was utilized, including naturalistic observations, interview data, and surveys. Mother-child dyads were video and audio-recorded as they visited four different exhibits: two low immersion exhibits and two high immersion exhibits. Interview data was collected from children immediately following the visit to assess learning. Survey data was collected from mothers to assess education, environmental predispositions, and science-related career. In high immersion exhibits, mothers and children spent more time and asked …

Exhibiting Sovereignty: Tribal Museums In The Great Lakes Region, 1969-2010, Meagan Mcchesney

Dissertations

This dissertation argues that the foundation and development of tribal museums in the Great Lakes region is a form of activism -- a deliberate action performed for the purpose of inciting positive political, social, cultural, and/or economic change -- and that the functions of tribal museums enable Native activism to continue and evolve to reflect and address new historical understandings and contemporary circumstances. I argue that in the Great Lakes region, Native activism continued beyond the highly publicized movement of the 1960s and 70s, and manifested in ways suited to address regionally and tribally-based needs. Control over interpretations of the …

Dissertations

This study presents the findings of a content analysis of student handbooks from 23 public high schools in a suburban Illinois county. A checklist was utilized to compare discipline policy information between handbooks published in the school years prior to and following implementation of Illinois Senate Bill 100. The results included 20 of the 23 schools' handbooks demonstrating an increase in their reflection of Senate Bill 100 requirements from the 2015-16 to 2016-17 school years with approximately half of the schools modifying handbook language from pre- to post-implementation years to remove zero-tolerance policies and reflect policies aligned with the Senate …

Characterization Of The Effects Of Sex And Estrogen Receptor Signaling On Antigen-Specific T Cells For Immunotherapy, Flor Cecilia Navarro Negredo

Dissertations

Adoptive cell transfer (ACT) immunotherapy using antigen (Ag)-specific T cells is partially effective treating several malignancies but numerous challenges remain in order to improve its therapeutic potential. The roles of host factors, such as sex hormone receptor signaling, that can affect the T cell anti-tumor function remain understudied. The work performed in this dissertation characterized the role of estrogen signaling on T cell function in vitro, and during ACT immunotherapy against hepatocellular carcinoma (HCC) in vivo. Estrogen signaling through ERa enhanced the expression and secretion of Type I effector cytokines including IFNg, TNFa, and Granzyme B in male and female …

Protection From Staphylococcus Aureus Bloodstream Infection By Probiotic Exopolysaccharide, Wonbeom Paik

Dissertations

Staphylococcus aureus is known to cause severe systemic infection with high mortality rates. Antibiotics are the only approved therapy for patients, but the widespread prevalence of antibiotic resistant strains limits treatment efficacy, and many patients succumb to the disease. Many probiotic agents are commercially available, but the mechanisms by which they benefit are not known. Understanding these mechanisms will help develop novel therapeutics that can improve healthcare, including systemic infections by S. aureus. Bacillus subtilis is a probiotic bacterium that produces an exopolysaccharide (EPS) that induces anti inflammatory macrophages (MΦ). We tested if EPS could be used for systemic S. …

Prevalence And Potential Buffers Of Intergenerational Trauma In African American And Latinx Parent-Child Dyads, Kandace Thomas

Dissertations

Buffering intergenerational trauma (IGT) is of great interest to researchers, policy makers and interventionists working to reduce the experience of trauma across generations within the family. IGT has been well studied among families who experienced the Holocaust and there is emerging IGT literature describing the impact of historical events and societal-based adverse experiences across generations. This study expanded upon the IGT literature by exploring and confirming the existence of IGT in a sample of primarily low-income African American and Latinx parents and their 6-year-old children; exploring pre-existing strengths and qualities in parents, such as Contemplative Self-Care (CSC) and Parent Self-Efficacy …

Addressing The School-To-Prison Pipeline Through Critical Self Reflection: A Self-Study Of Courageous And Transformative Leadership, Ernest D. Williams

Dissertations

Research reveals that zero-tolerance policies lead to school suspensions of a disproportionate number of African American students in urban areas (Center for Civil [CCRR], 2015). Suspensions increase student failure rates and dropout likelihood and reduce the ability to graduate on time (Skiba, Arrendondo, & Williams, 2014). Studies have also shown that African American students are suspended three times more than their White American peers and two times more than their Latino American peers (CCRR, 2015). This has impelled federal and local government agencies, community organizations, and educators to question the effectiveness of punitive discipline policies that have marginalized black and …

Yczr, A New Case Of Plp-Dependent Mocr/Gabr Type Transcription Regulator In Klebsiella Pneumonia, Yuanzhang Zheng

Dissertations

Increasing number of genes encoding PLP-dependent transcription regulators, MocR/GabR type regulators, have been identified in various bacterial genomes. However, only a handful of them, including MocR, PdxR and GabR have been studied experimentally. They control different aspects of the bacterial metabolism. Only GabR has reported crystallographic structures. MocR/GabR regulators possess a chimeric structure consisted of a WHTH DNA binding domain and an Aminotransferase-like regulation domain, which can bind PLP as an effector in transcription regulation. Such a chimeric construct presents an interesting case in molecular evolution. The regulation domains of All MocR/GabR type regulators loss their catalytic capacity during evolution …
