See Me From Behind The Screen: Workplace Ostracism In A Remote Environment, Quiméka Nicole Saunders

Dissertations

Workplace Ostracism is a common social phenomenon that impacts individuals of diverse backgrounds, across various industries, and cultural experiences. Literature to date highlights direct and indirect relationships of workplace ostracism, concerning the psychological and behavioral outcomes an individual may experience and the impact to organizational goals. Of existing literature, studies have focused on acts of ostracism conducted in face-to-face (F2F) environments or in F2F workplace situations. With the COVID-19 Pandemic, many companies were forced into teleworking situations, where work continues to be conducted outside of the central work office or facility (remote). With the shift in working environments, the prevalence …

Workplace Violence Prevention Training: A Cross-Sectional Study Of Home Healthcare Workers, Tamara F. Small

Dissertations

HHCWs are at increased risk for WPV due to working alone in unsupervised, unpredictable, and potentially dangerous work environments. Similar to healthcare workers employed in institutionalized settings, HHCWs primarily experience Type II, verbal abuse from patients. Little is known about how HHCWs promote personal safety while at work. Guided by Haddon's Matrix, the purpose of this manuscript option dissertation was to estimate WPV exposures and identify interventions and resources used by HHCWs to promote personal safety and mitigate and prevent WPV. For this manuscript option dissertation, there are three distinct projects, all related to HHCWs and exposure to WPV.

It's More Than Nursing: The Experience Of Psychological Safety Of Pre-Licensure Nursing Students Who Identify As Black, Indigenous, And People Of Color, Melissa M. Anozie

Dissertations

The healthcare environment mandates its staff are able to communicate freely and openly to provide high quality patient care leading to positive patient outcomes. As the largest healthcare profession and those who are at the bedside most often with patients, registered nurses play a vital role in ensuring these outcomes. As advocates for the most vulnerable, nurses must communicate often but before doing so, they must feel psychologically safe. Psychological safety is how one perceives the benefits, risks, and consequences of asking a question, sharing an opinion, reporting an error, or revealing one's true self to others. It is a …

The Influence Of Practice Experiences On Feelings Of Role Proficiency In Emergency Nurse Practitioners: A Phenomenological Study, Daniel Monk

Dissertations

The evolution of this research emerged from experiences in the researcher's clinical practice as a nurse practitioner in a variety of urgent care facilities, and the personal queries raised regarding the consistency of the level of practice and evidenced competency of clinical staff in emergency and unplanned care using the title ";practitioner";. These realities are apparent as at present in the UK no legislative requirement exists for nurse practitioners (NPs) to gain formal preparation or qualification. Guidance and direction have been seen in The Advanced Care Practice framework (HEE,2017), yet legislative protection remains absent. Such legislative protection is however seen …

A Multiscale Linkage Between Riverscape And Fish Community Coevolution, Loren W. Stearman

Dissertations

Sediment dynamics are foundational to stream and watershed morphology. Yet aquatic ecologists have relied on an oversimplified model of sediment dynamics characterizing sediments as agents of stream bed burial, and which fails to describe many types of aquatic habitat evolution. In this dissertation I employ both fluvial geomorphic and ecological frameworks to gain a deeper understanding of how sediment dynamics shape stream morphology and fish community evolution at multiple scales. Using a paired historic and contemporary approach, I analyzed geomorphic evolution and fish community change in the Bayou Pierre, Mississippi, from the 1980s to recent. Patterns of erosion due to …

Improving Recognition Of Depression Among The Older Adult Population, Keirstin E. Uomoto

Dissertations

Depression is a common mental health disorder faced by older adults that can go undetected and untreated. It was determined that the project site was not using a screening tool for depression among their patient population to identify or treat possible depression. The purpose of this quantitative, quasi-experimental quality improvement project was to determine if the implementation of Yesavage's Geriatric Depression Scale-15 (GDS-15) would impact the identification of risk factors for depression and the initiation of pharmacological treatment, follow-up, and referral to a mental health specialist among adults 65 and older.

Further, extensive work has focused on expanding the synthetic toolbox for these systems, resulting in excellent molecular weight control, diverse functional group utility and corresponding stimuli-responsive behaviors. This dissertation examines both synthetic and stimuli-responsive tools in the context of bottlebrush systems.

A broad overview of bottlebrush characteristics, synthesis, and applications is discussed in CHAPTER I. CHAPTER II focuses on the use of a chain-transfer agent in the ring-opening metathesis polymerization …

Transportation Managers’ Perceptions Of The Diffusion Of Innovation Within Logistics Clusters, Stephen Mcdonald Puryear

Dissertations

The human capital capacity for innovation is crucial for business success. Cluster theory posits that this capacity for innovation is enhanced by industrial clustering geographic proximity. The innovative capacity is expected to be facilitated by institutions for collaboration, informal knowledge flow, short feedback loops, and collective action regimes. Research on logistics clustering has supported this supposition. Still, no research has explicitly examined whether being physically located in a logistics cluster enhances a company’s human capital capacity for innovation.

This study uses the Interpretive Phenomenological Analysis (IPA) approach to determine the innovative operational processes involved in the diffusion of innovation within …

Perceived Gender Norm Adherence In Women As Function Of Sex-Typical Facial Features And Surname Decisions, Kelsey Drea

Dissertations

Women’s retention of their surname following marriage has become increasingly common despite pervasive stereotypes of this stereotype as leading to relational failure. It could be possible that women’s physical appearance could buffer them from these stereotypes, particularly if that appearance is sex-typical. This study investigated how feminized facial structures could buffer women from negative perceptions of their abilities in relationships. Participants assessed a woman described as having changed or kept her surname. This woman’s face varied in her sex typicality (i.e., feminized, masculinized, unaltered). Feminine women appeared more modest when they kept their surname. Hostile sexism predicted less relational success …

Nursing Students Strengthening Resiliency Through Educator Relationships: A Basic Qualitative Study, Sandra Mcdade

Technologies and online learning platforms have changed the contemporary educational paradigm, giving institutions more alternatives in a complex and competitive environment. Online learning platforms, learning-based analytics, and data mining tools are increasingly complementing and replacing traditional education techniques. However, academic underachievement, graduation delays, and student dropouts remain common problems in educational institutions. One potential method of preventing these issues is by predicting student performance through the use of institution data and advanced technologies. However, to date, scholars have yet to develop a module that can accurately predict students’ academic achievement and commitment. This dissertation attempts to bridge that gap by …

Comparing The Efficacy Of Two Inclusivity Interventions On Willingness To Invest In Female- Versus Male-Led Stem And Non-Stem Companies, Alicia Macchione

Dissertations

A notable gender asymmetry has been historically prevalent in science, technology, engineering, and mathematics (STEM) fields. Recent work has shown how gender-inclusive advertisements can increase women’s interest in pursuing these fields as indexed by college course enrollment, which could occur through reminders of moral and pragmatic utilities of gender inclusivity. This dissertation extended prior work by determining if inclusivity priming can be leveraged to facilitate financial investment in hypothetical STEM and non-STEM companies led by either a male or female CEO. Participants were first primed with a statement describing the pragmatic utility of gender inclusivity in STEM, a moral statement …

Reactive Additive Manufacturing Of Polyurethanes: Simultaneous Polymerization And 3d Printing, Aynslie Fritz

Dissertations

Relationships between polyurethane (PU) design and chemorheological properties were correlated with ambient reactive extrusion (ARE) additive manufacturing (AM) processing conditions. PUs synthesized from varying monomeric and polymeric isocyanates, hard segment concentrations, crosslinkers, and additives were systematically designed to elicit differences in chemorheological properties and efficacy. Variations in PU composition and experimental procedures were evaluated to establish a baseline of PUs for ARE. PUs were synthesized and monitored throughout polymerization by rheological and real-time infrared spectroscopy techniques to observe moduli development and functional group conversion, respectively. Observed experimental properties were correlated with critical ARE parameters, such as dimensional stability at deposition …

Impacting African American Student Achievement In The Middle School Stem Classroom By Teaching Mathematics Through Arts Integration And Design Thinking, Robert Lippert, Tjuannia R. Seals

Dissertations

Middle school is a transitional period in which many students experience content-specific teachers, travel between classrooms, and explore extracurricular activity options for the first time. Historically, African American middle school students have not fared well in Science, Technology, Engineering, and Mathematics (STEM) on standardized assessments, performing significantly below their Caucasian counterparts in mathematics and science. From the beginning of their academic careers, a lack of access to quality teachers, excessive use of direct instruction strategies, and a lack of resources in their school communities, contribute to their overall apathy towards the subject matter and factor into their underperformance. As a …

Perceptions Of Undergraduate Nursing Students On Racism And Racial Disparities In Maternal Health, Monika Costa

Dissertations

The United States has persistent racial inequities in maternal health, with African American women experiencing the highest maternal mortality and morbidity (Centers for Disease Control and Prevention, 2020). Structural inequities, racism, implicit and explicit biases, and discrimination contribute to disparities in maternal health outcomes in the United States (Alshusen et al., 2016; Davis, 2019; Institute of Medicine, 2003, Liese et al., 2019, National Academies of Sciences, Engineering, and Medicine, 2020). In recent years, racial discrimination and bias have been important topics of discussion.

Student Nurses' Perception Of Preceptors' Authentic Leadership Effect On Self-Efficacy, Venise D. Bryan

Dissertations

The study examined the relationship between final year nursing students' perceptions of preceptor authentic leadership and self-efficacy. Nursing students are required to engage in a preceptorship experience at the end of their nursing education for socialisation into the profession and learning consolidation to facilitate optimum transition from student to nurse. Unfortunately, preceptorship has been identified as the most stressful experience that nursing students engage in and poor relations with clinical staff and low competence beliefs to nurse have led to attrition after graduation. To date, a limited number of studies have examined preceptors' leadership style, particularly authentic leadership and student …

The Influence Of Knowledge And Value On Nursing Students' Quality Of Supportive Feedback To Peers, Joni L. Tornwall

Dissertations

Peer review in nursing is an expectation of every registered nurse in the workplace, and it is essential to accountability and self-regulation of practice in the nursing discipline. However, the literature reveals that professional nurses and nursing students feel peer review is not their responsibility. Research has shown that they state they do not have time to do it, and they feel unprepared for and anxious about the process of providing good feedback to peers. Academic nursing programs should be teaching future nurses to participate in peer review and recognize its value to professional nursing practice. Training in peer review …

Influence Of Leadership Styles On Expatriate Nurses' Professional Integration In The Uae, Emmah Ncube

Dissertations

Transnational nurse migration has evoked a growing interest in the phenomenon of professional integration of expatriate nurses into their host societies.

Dissertations

The typical collegiate introductory statistics course poses significant challenges for students. Many do not fully comprehend key course skills, and it is common for students to exit the class with a neutral or negative attitude toward statistics. To measure the impact of using relevant contextual examples as an instructional strategy during a probability unit, in-class activities were designed to align with areas of interest for participants as identified by a student interest inventory. It was hypothesized that the use of relevant context would create a significant difference in the comprehension or attitude of students enrolled in an introductory statistics course …

Probing Amyloid-Beta Protein Structure And Dynamics With A Selective Antibody, Shikha Grover

Dissertations

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder. The AD brain is characterized by significant neuronal loss and accumulation of insoluble fibrillar amyloid-β protein (Aβ) plaques and tau protein neurofibrillary tangles in the brain. However, over the last decade, many studies have shown that the neurodegenerative effect of Aβ may in fact be caused by various soluble oligomeric forms as opposed to the insoluble fibrils. Furthermore, the data suggest that a pre-fibrillar aggregated form, termed protofibrils, mediates direct neurotoxicity, and triggers a robust neuroinflammatory response.

Antibodies targeting the various conformation of Aβ are important therapeutic agents to prevent the progression …

Magnetic Interactions In Open-Shell Conjugated Polymers, Michael Steelman

Dissertations

Most materials are closed shell in which every electron participates in a bond, resulting in unremarkable magnetometry signatures and functionalities. While rare, modern technologies rely on magnetic materials in which unpaired electrons are localized to inorganic atomic centers. In recent decades, a collection of organic open-shell π-conjugated molecules have shown magnetic ordering, albeit at exceedingly low temperatures; a result of weak noncovalent intermolecular interactions limiting long range electronic exchange. Thus, practically applicable sp orbital magnetism that persists at or above room temperature remains a grand challenge for chemistry and physics. Despite the wide variety of chemical structures afforded by organic …
