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, …

Chaos Is Not Rational: Nursing Leadership And Intuition In Disaster Preparedness And Response, Sarah Banks

Dissertations

Nurses are looked upon as leaders in disaster preparedness and response. Charged with making life-altering decisions, experienced nurse leaders utilize analytical and intuitive strategies to manage crisis situations. Rarely recognized by upper-level management and educational institutions, intuition is our natural ability to know something without any evidence or validation. Intuition allows us to make decisions in ever-changing circumstances when solutions are not obvious. Though difficult to explain, intuition is a powerful skill that gives nurse leaders the confidence needed to make decisions based on their previous experience. Experienced nurse leaders utilize intuition to arrive at a solution without conscious awareness …

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 …

Investigating Smooth Muscle Myosin Dynamics And Assembly In Physiology And Pathology, Maggie Bennett

Dissertations

Vascular smooth muscle cells (SMCs) surround many blood vessels throughout the body,where they dynamically alter vessel diameter to regulate blood pressure, provide structural integrity, and absorb shock on a beat-to-beat timescale. As smooth muscle function fails, profound vascular disease ensues, often with tragic results- even death. Smooth muscle myosin 2 (SM2) is the dominant motor protein that actuates contractility and allows SMCs to perform these vital functions. To function, SM2 monomers dynamically assemble into filaments, which upon SMC activation, associate with filamentous actin to drive contractility. Despite the critical contribution of SM2 to SMC function, foundational aspects of SM2 assembly …

Investigating The Impact Of Nonenzymatic Lysine Acetylation On The Function Of The Bacterial Ribosome, Sarah Caldwell Feid

Dissertations

An under-investigated target of lysine acetylation is the bacterial ribosome. Although lysine acetylations on the ribosome are common and conversed in diverse bacterial species, little work has been done to understand how lysine acetylation affects the bacterial ribosome. The goal of this work is to determine if lysine acetylation has functional impact on the bacterial ribosome.I have identified in vitro and in vivo effects of nonenzymatic, AcP-dependent lysine acetylation on translation and the ribosome. In vitro acetylation of transcription-translation reactions causes a translation-specific defect that is unaffected by the addition of the CobB deacetylase. This suggests certain AcP-sensitive residues that …

Dissertations

Local partners like churches, schools, and community organizations are often at the front lines of addressing the problem of recurring deadly violence against Black urban youth. Foundation grants are frequently used to fund their work. While foundations annually award millions of dollars in grants to community-based organizations addressing youth violence, there is little detailed information available about the foundation grantmaking decision-making process. Notably, there is a lack of research on the determinants of the grant decision-making process that may inadvertently affect grantee outcomes and ultimately the of beneficiary organizations and communities.A sample of ten decision-makers who had funded or sought …

Gardening And Watering 21st Century Soil: Culturally Responsive And Technology Enhanced Instructional Design In K12 Schools, Elissa W. Frazier

Dissertations

Decades of research have documented the positive impact of culturally responsive teaching on academic outcomes for African American and LatinX students. However, as the field of education has become increasingly embedded with technology as a powerful tool of instruction, more attention is needed to understand how culturally responsive teachers use technology to close achievement gaps. Although national public policy over the last twenty-years has documented the negative impact of the digital divide on low SES, African American and LatinX students, large-scale efforts to close the divide have focused primarily on access to devices only. More recently, the second digital “use” …

Contributions To Data Compression Research For Various Media Formats Using Particle Swarm Optimization And Neural Networks, Reetu Hooda

Dissertations

Advancement in high resolution devices used to capture images and videos has put strain on data storage and transmission. For their practical usage, efficient data compression techniques becomes essential. In this context, we conducted a study on compression of two media formats, including ROI maps of hyperspectral images, and 3D point clouds. For lossless compression of ROI maps, we proposed novel schemes that can achieve high compression ratios by partitioning the intricate regions of the image into smaller blocks. Our analysis of a linear predictive model applied on the original images showed that the resulting residual images tend to have …

Understanding The Sequence Specificity Of Ribosome Arresting Peptides, Heather Nicole Gentle

Dissertations

Regulatory arrest peptides (RAPs) fine-tune gene expression based on physiological cues from internal and external environments. These peptides, generated from upstream open reading frames in bacteria and eukaryotes, function by conditionally arresting the ribosome to control the fate of associated messenger RNAs (mRNA). Commonly, RAPs contain two functional domains composed of conserved residues that are critical for ribosome arrest called the sensor and stalling domains. The sensor domain allows the peptide to monitor outside or within the ribosome for its inducer molecule by folding into secondary structures that produce a binding site. The stalling domain slows the rate of translation …

By Chameleonic Means; "Trust Based" Philanthropic Relationships, "The Business Of Yes," As Experienced By Black Fundraisers, Novien Yarber

Dissertations

In the wake of society’s reinvigorated consciousness around structural and systemic racism, conversations centering justice, equity, inclusion, access, and cultural diversification are going far beyond political discourse. Contemporary fundraising practices are also challenging antiquated hegemonic ways of philanthropy and are critically examining the practice from within. Among many things, this entails diversifying the historically White-female dominated fundraising workforce. In this, fundraising literature has paid minimal attention to intercultural/cross-racial dynamics as implications of diversification of the fundraiser workforce. Although some research may center fundraisers themselves (relative to their ethical and/or professional standards), this dissertation expands this field of study by offering …

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 …

The techniques that secure coders utilize to analyze source code and develop mitigation strategies for security flaws are not well understood. Gaining a proper understanding of how coders approach finding and mitigating security flaws can help us efficiently and accurately discover and resolve such issues. One potentially beneficial technique is to collect, analyze, and visualize eye gazes that capture their coding patterns and behaviors. Our systematic literature survey focused on published methods for multiple types …

“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 …

“The Issue Is Already There; Just Have The Conversation!”: Culturally Sustaining Reflection In The Student Teaching Triad, Hanna M. Asrat

Dissertations

There is a vast demographic mismatch between California’s public school teachers (who are majority White, mono-lingual English-speaking women) and California’s public school students. Though universities responsible for educating preservice teachers often include coursework that attempts to help address this demographic mismatch, such as instruction about Culturally Sustaining Pedagogy, if preservice teachers do not get the chance to practice this pedagogy in their fieldwork placement, they tend to fall into to the two-worlds problem. The two-worlds problem posits that preservice teachers view constructivist and Culturally Sustaining Pedagogies learned at the university as theoretical and incompatible with actual teaching, and so they …
