Work And Family Conflict: A Comparative Analysis Among Staff Nurses, Nurse Managers, And Nurse Executives, Amanda Raffenaud

Electronic Theses and Dissertations

The nursing workforce increasingly faces issues that affect clinical and managerial practice. One such issue is work-family conflict (WFC) and family-work conflict (FWC). Nurses face role strain as they confront the pressures from often competing work-and-family roles. This study assessed WFC/FWC among varying nurse roles: staff nurses, managerial nurses, and nurse executives. A random sample of 5,000 nurses, generated from registered nurses practicing in the state of Florida, was surveyed for this research study. Nurses were surveyed on demographics, perceptions regarding the work environment, and perceptions of WFC/FWC. Descriptively, nurses experienced more work-family conflict than family-work conflict.

Assessing The Impact Of Meaningful Employment On The Self-Esteem Of Male Veterans, Gary Grimes

Electronic Theses and Dissertations

This dissertation examined the relationship between meaningful employment and self-esteem in male veterans. Meaningful employment is an important element of reintegration, the process all veterans go through to transition from active duty military service back into society. Reintegration involves three major areas: physical and mental health, employment, and family and friend relationships. A sample of 30 male veterans were interviewed. After the interviews, two instruments were used to further examine the variables (meaningful employment and self-esteem). The instruments were administered to measure the individual's perception regarding meaningful employment and level of self-esteem. The interviews were the primary focus, with the …

Characterization, Classification, And Genesis Of Seismocardiographic Signals, Amirtaha Taebi Jan 2018

Characterization, Classification, And Genesis Of Seismocardiographic Signals, Amirtaha Taebi

Electronic Theses and Dissertations

Seismocardiographic (SCG) signals are the acoustic and vibration induced by cardiac activity measured non-invasively at the chest surface. These signals may offer a method for diagnosing and monitoring heart function. Successful classification of SCG signals in health and disease depends on accurate signal characterization and feature extraction. In this study, SCG signal features were extracted in the time, frequency, and time-frequency domains. Different methods for estimating time-frequency features of SCG were investigated. Results suggested that the polynomial chirplet transform outperformed wavelet and short time Fourier transforms. Many factors may contribute to increasing intrasubject SCG variability including subject posture and respiratory …

Low Income And First Generation Students' Engagement Of Authority Figures, Josalie Condon Jan 2018

Low Income And First Generation Students' Engagement Of Authority Figures, Josalie Condon

Electronic Theses and Dissertations

Background: Numerous studies acknowledged the potential struggles that first generation (FG) and low-income students (LI) face as they attempt to navigate the college degree pipeline. One struggle these students may face is an aversion to engaging authority figures. Unlike their peers, both FG and LI students can come from families with little to no college literacy, and this lack of support, coupled with not seeking out assistance from authority figures on campus, could lead to potential problems. This lack of engagement with authority figures may be related to childhood socialization such as Cultivation of Intellectual Independence (CII). Individuals with high …

Development Of A Non-Human Primate Model For Staphylococcus Aureus Nasal Carriage, Amanda Lasseter Jan 2018

Development Of A Non-Human Primate Model For Staphylococcus Aureus Nasal Carriage, Amanda Lasseter

Electronic Theses and Dissertations

Staphylococcus aureus nasal carriage (SANC) is largely asymptomatic, but presents a risk of autoinfection and dissemination to new immunocompromised hosts. SA disease states range from mild cutaneous infections to life-threatening bacteremia. Historically utilized rodent models do not naturally carry SA in the nose, are insufficient in longitudinal SANC experimentation, and lack immune factors that are vital in human clearance of SA. The nasal passages of non-human primates are similar anatomically and histologically, and reproductive mucosal studies have shown similar immune responses to pathogens and human-relevant microbial profiles. Seventeen captive pigtailed macaques (Macaca nemestrina) were found to naturally carry SA in …

Boots On The Ground: A Participant-Oriented Approach To Program Evaluation, Nikki Djak Jan 2018

Boots On The Ground: A Participant-Oriented Approach To Program Evaluation, Nikki Djak

Electronic Theses and Dissertations

Despite best efforts to fully prepare pre-service teachers (PSTs) with the knowledge and skills they will need as educators, many universities nationwide fall short of doing so. Poor or unrelated pre-service preparation of education majors prior to graduation creates disconnects between college coursework requirements and real-world expectations of educators, which decreases the value of these education programs. It also leaves many PSTs entering internship and subsequent first-year employment ill-prepared to handle all of the classroom responsibilities expected of them, which contributes to another nationwide problem: low retention of novice teachers. To address comprehensive preparation of PSTs, professors at one large …

Warrior Women: A Phenomenological Study Of Female Veterans Transitioning Into And Through College, Alma Sorensen Jan 2018

Warrior Women: A Phenomenological Study Of Female Veterans Transitioning Into And Through College, Alma Sorensen

Electronic Theses and Dissertations

Current research and theory primarily focuses on identifying holistic challenges of the veteran student demographic and does not focus on challenges specific to female veterans when transitioning into and through college. Additionally, current research and theory does not focus on positive and negative experiences of female veterans within four key areas of academia: courseware, faculty, staff/administration, and student services. As a result, current research and theory do not adequately explain why female veterans may or may not successfully transition into and through college, resulting in a lack of resources available for female veterans, and Higher Education Institutes (HEIs). This phenomenological …

Revisiting The Postclassic Burials At Lamanai, Belize: A Second Look At The Unique Ventrally Placed, Legs Flexed Burials., Victoria Izzo

Electronic Theses and Dissertations

Analysis of unique mortuary patterns is often used to evaluate the social lives of the deceased and also those of the living who placed them there. The Ventrally Placed, Legs Flexed (VPLF) burials at the site of Lamanai in Belize, dating to the Postclassic period (1000 - 1544), have been recorded as a Maya mortuary pattern since the late 1970's. While many researchers have analyzed these skeletal remains, comprehensive and cumulative individual analysis of the VPLF individuals from Lamanai has not been conducted. In this study, I will argue that the VPLF individuals in this study were local to Lamanai, …

Embryonic Stem Cell Derived Exosomes Enhance Cardiac Stem Cell Differentiation Into Heart Cells, Jamillah Hammond Jan 2018

Embryonic Stem Cell Derived Exosomes Enhance Cardiac Stem Cell Differentiation Into Heart Cells, Jamillah Hammond

Electronic Theses and Dissertations

Transplantation of embryonic stem (ES) cells into the ischemic and infarcted heart has proven to repopulate cardiac cell populations, attenuate structural cardiac remodeling, and rescue cardiac function. Unfortunately, the pluripotency of ES cells increases risk of teratoma formation in vivo. Exosomes, smaller in comparison to ES cells, are cell free carriers of miRNA, proteins, and lipids, and do not suggest risk of teratoma formation. Exosomes have been proposed to mediate and attenuate regeneration following myocardial infarction (MI), however, the role of exosomes derived from ES cells (ES-Exo) in activating resident cardiac stem cells (CSCs) to undergo cardiac differentiation is not …
