A Quantitative Study Of The Relationships Among Psychological Safety, Collaborative Capacity, And School Climate In Middle-Level Schools, Karen Brownfield

Dissertations

This quantitative study was conducted to investigate possible relationships between psychological safety, collaborative capacity, and school climate in middle level schools in order to identify specific leadership behaviors to increase collective efficacy. School leaders’ knowledge of the positive effect collective efficacy has on student learning is not enough (Donohoo & Katz, 2019; Parrett & Budge, 2020). Leaders must also be aware of functional behaviors to foster collective efficacy, thus increasing student learning (Donohoo & Katz, 2019). Based on the theoretical work of Bandura (2000, 2012), as well as DeWitt (2017), Garmston and Wellman (2013), Hattie (2017, 2019), and Rock (2013), …

The Effect Of Using The Adaptive Crawler™ On The Development Of Infants With Spina Bifida, Age 6-12 Months, Margaret E. Williams

Dissertations

During the timeframe of crawling, age 6--12 months, infants typically interact independently with their environment and their parents in order to perform certain developmental tasks. However, many infants with spina bifida are unable to crawl, as would typically developing infants. The inability to crawl may place these infants at a distinct disadvantage during this developmental timeframe. As a result of the developmental disadvantage, the parent-infant relationship may be negatively affected. For this study, the Adaptive Crawler™ assistive technology infant mobility device was designed, and a prototype created, to promote independent mobility and exploration of their environment by infants with spina …

Improving Maternal Outcomes Through Quantifying Blood Loss In Cesarean Sections, Michelle R. Barrier

Dissertations

Abstract

Problem: Postpartum hemorrhage is a preventable, leading cause of maternal death in the United States and is a direct result of a delay in diagnosis, intervention, and treatment of postpartum hemorrhage. Inaccurate measurement of blood loss from the use of estimation instead of quantitative techniques leads to a failure to recognize and respond appropriately. While there are risk factors for postpartum hemorrhage, all pregnant women are at risk.

Methods: This Quality Improvement (QI) project used a descriptive cohort study design, utilizing a retrospective chart review, to evaluate the quantification of blood loss during cesarean sections on maternal outcomes. Data …

Liquid Biopsies For Type 2 Diabetes Mellitus: Biomarkers For Disease Risk And Diagnosis, Stephanie Chidester

Dissertations

Background: Type 2 diabetes mellitus (T2DM) has reached epidemic proportions in the United States. There is a critical need for earlier and more effective screening and diagnostic tools. Innovative liquid biopsy technologies may play a key role in meeting this need. Liquid biopsies are a non-invasive, adjunctive tool for determining diagnosis, prognosis, and therapeutic response. This dissertation focuses on two potential applications of liquid biopsy technologies to T2DM: (1) epigenome-wide association studies to identify epigenetic markers of risk for T2DM, and (2) extracellular vesicle (EV)-based biomarker studies to identify and detect markers associated with T2DM development and progression. Dissertation studies: …

Heart Rate Variability Following Treatment For Ptsd: Testing The Polyvagal Theory, Brittany F. Goodman

Dissertations

Posttraumatic stress disorder (PTSD) has been linked to lower heart rate variability (HRV), including measures of vagal tone. Treatments targeting the autonomic nervous system (ANS) have demonstrated efficacy in improving vagal tone, but it is less clear whether similar effects can also be achieved with cognitive therapies. The polyvagal theory has suggested that symptoms of social dysfunction are linked to vagal tone through a phylogenetically organized response to stress. HRV was collected during rest, reactivity (exposure to personalized trauma scripts), and recovery using a scripted imagery paradigm in female PTSD positive physical and sexual assault survivors (N = 41) …

Student Attitudes Towards Graduation: A Comparison Of Motivation Factors For Greek Life And Non-Greek Life Undergraduate Students, Crystal Sanders

Dissertations

Greek life is an activity that is part of student involvement on a college or university campus. Student involvement allows students to increase their knowledge outside of the classroom through interaction with their peers and faculty, which will hopefully lead to graduation. The creation of Greek life engaged students in activities outside of the classroom. Unfortunately, Greek life has carried negative references and has been associated with morally wrong activities. Colleges and universities received negative impacts from such activities and behaviors. Most research about Greek life conveyed dedication to focusing on hazing, academics, and graduation rates. Revealing the motivational influences …

Perioperative Experience Of Adolescents, Janean Carter Monahan

Dissertations

Research has shown that preoperative stress is associated with poorer health outcomes in adults and young children, but there is little in the literature about the stress experienced by adolescents. Clinical experience, however, has shown that adolescents behave differently throughout the perioperative experience than either adults or children. For example, common behaviors of adolescent's emerging from anesthesia include combativeness, thrashing, and crying. To promote adolescent health and to provide adolescents with appropriate interventions that will support a positive surgical outcome, research is needed to discover the perceptions and meanings adolescents attribute to the perioperative experience.

The purpose of this hermeneutic …

Investigating The Role Of Fun30, A Chromatin Remodeler, In Dna Repair, Mehwish Iqbal

Dissertations

The repair of DNA double-strand breaks (DSBs) is crucial for maintaining genome stability. DSB repair needs to take place within the complex organization of the chromatin, and this requires changes in the chromatin structure adjacent to DSB sites. These changes occur through covalent histone modifications that alter histone-DNA contacts as well as by the action of ATP-dependent chromatin remodelers. Many chromatin remodelers, including Fun30, are involved in DSB repair. Fun30 facilitates DNA end resection at DSB site during the homologous recombination repair pathway. Apart from its role in DNA repair, Fun30 promotes gene silencing at heterochromatic loci such as telomeres, …

Unsupervised Learning With Word Embeddings Captures Quiescent Knowledge From Covid-19 And Materials Science Literature, Tasnim H. Gharaibeh

Dissertations

Millions of scientific papers are produced each year and the scientific literature is continuing to grow at a head-spinning speed. Thus, massive scientific knowledge exists in solid text, but all these publications make it difficult, if not impossible, for researchers to keep in up to date with discoveries, even within a narrow scientific area. This massive amount of information also makes it difficult to find implicit and hidden connections, relationships, and dependencies within the information that may guide the direction of future research or lead to valuable new insights. So, there is a need for algorithms or models that can …

Holism, Philanthropy, And Community Self-Determination: A Case Study Of Urban Sustainability Logics In Kalamazoo, Robert Roznowski

Dissertations

The social, economic, and ecological crises of contemporary cities have compelled some communities to pursue urban sustainability agendas. In the United States, municipal governments and local actors engage with a myriad of urban sustainability discourses and “logics” that shape urban sustainability agendas. The literature suggests that urban sustainability discourses and logics are shifting in ways that are more “selective” or exclusive of spaces, issues, and people. This study investigates the urban sustainability logics taking shape in Kalamazoo, Michigan. Most existing research focuses on large cities with well-established urban sustainability agendas. In contrast, this case study focuses on the urban sustainability …

The Influence Of Integrated Behavioral Health Primary Care Setting On The Utilization Of Mental Health Services And Depression Treatment Response Among Men, Tendai Masiriri

Dissertations

The 2010-2013 National Health Interview Survey showed that nearly 9% of men had daily feelings of anxiety or depression, yet less than 41% sought help for their symptoms (Blumberg et al., 2016). Men are more reluctant than women to seek help (Angst et al., 2002; Brownhill et al., 2005). The failure to seek help among men is associated with multiple factors related to stigma and gender, yet male suicide rates are approximately 3-5 times higher than their female counterparts. However, they have a higher likelihood of seeking help from a medical provider rather than a mental health provider. If men …

Experimental Insights Into The Origin Of Microcrystalline Calcites, Mohammed Hashim

Dissertations

A significant proportion of modern marine calcium carbonate sediments is dominated by metastable aragonite and high Mg calcite that either dissolves or stabilizes to low-Mg-calcite (calcite) or dolomite during diagenesis. Sediment dissolution and stabilization have implications for the CaCO3 budget in the ocean and carbon burial rates. Yet, the diagenetic conditions that promote each process and their relative importance are poorly understood. Further, stabilization most commonly produces calcite microcrystals that exhibit various textures and host micropores. Despite their ubiquity in the rock record, the controls on microcrystal textures remain unclear. Here, laboratory experiments were used to investigate aragonite-to-calcite stabilization as …

Ocean Quahog (Arctica Islandica) Population Dynamics: Sex-Based Demographics And Regional Comparisons In The Northwest Atlantic, Kathleen M. Hemeon

Dissertations

Arctica islandica (ocean quahog) is the longest-lived bivalve on Earth. Individuals on the deep continental shelf of the Mid-Atlantic (US) can survive for centuries, and when found in the colder, boreal waters of Iceland, ages over 500 years can be reached. The ocean quahog is important in the US, yet very little is known about the resiliency of the ocean quahog stock to fishing activity, and ocean quahog recruitment patterns over time. To quantify and constrain age-reader error prior to age analysis, a triple-method error protocol was developed for A. islandica that included age-reader bias, precision, and error frequency. The …

The Mitigation Of In-Group And Outgroup Biases: Understanding The Perceptions Of Educators On The Contact Approach Theory, Brigitte Blazys

Dissertations

The contact approach theory was introduced in the 1950s, by Allport, as a method to mitigate biases. Since then, many DEI practitioners in the United States have formed alliances to create a social justice movement to combat racism, prejudice, and biases in our society. Nevertheless, little research has been conducted in the contact approach theory as these biases, initially observed as in-group and outgroup biases, originate in the early years of life. To begin to fill this gap in the literature, the purpose of this study was to better understand and identify to what extent, if any, prekindergarten through third …

The Effects Of Career Commitment, Distress, And Persistence On Academic Success Among Undergraduate Baccalaureate Nursing Students, Kimberly D. Kennel

Dissertations

The ability of students, specifically in higher education environments, to persist is a critical determinant of academic success. Student success is especially precarious within programs of nursing, where curricula include clinical, laboratory, and didactic content. Identifying and describing the barriers and facilitators to nursing student persistence provides a blueprint to appropriately use financial and human resources as well as determine the effect student demographic variables has on desiring, attending, or benefiting from persistence interventions. The outcome of this study can guide the deployment of institutional resources to provide persistence-based interventions that are evidence-based. Framed by Tinto's Theory of Student Departure, …

The Correlation Between Peer Support And Quality Of Life Of Nurses, Kim Diane Rose Maryniak

Dissertations

Nurses can experience stress and perceived traumatic events during their career. This distress in the workplace can affect the quality of life of nurses. Exposure to perceived distressing events may lead to burnout, compassion fatigue, post-traumatic stress disorder, patient errors or poor outcomes, horizontal violence or even nurses leaving the profession. Peer support is a strategy which has been explored to increase defensive lines and improve coping. The purpose of this descriptive, correlational study was to examine if a relationship exists between the use of peer support, as conceptualized within the framework of the Neuman System Model, and the quality …

Qualitative Analysis Of Older Adults' Experiences With Sepsis, Rebecca D. Hancock

Dissertations

Atypical symptoms, multiple co-morbidities and a lack of public awareness make it difficult for older adults to know when to seek help for sepsis. Diagnosis delays contribute to older adults' higher sepsis mortality rates. This research describes patients' and caregivers' experiences with the symptom appraisal process, self-management strategies, provider-nurse-patient interactions, and barriers when seeking sepsis care.

Handoff Communication Among Senior Nursing Students: A Phenomenological Study, Juanita Hanley-Gumbs

Dissertations

Despite discussions in health care regarding poor communication and its link to patient safety, it was revealed in the literature that many student nurses are inadequately prepared to conduct handoff communication. Student nurses have difficulty in this area due to limited or no experience with the handoff process, which jeopardizes patient safety. The purpose of this research study was to understand how senior nursing students make meaning of their lived experiences with handoff communication. The guiding research question for this study is: How do senior nursing students make meaning of their lived experiences with handoff communication during the change-of-shift report …
