Gestational Weight Gain Patterns, Hope R. Farquharson Phd

Dissertations

Background: Managing gestational weight gain (GWG) remains a global health priority as obesity among women of childbearing age and their children have been linked to excessive GWG. Excessive GWG has been linked to increased rates of cesarean sections, preterm births, hypertensive disorders, gestational diabetes, large for gestational age newborns, postpartum weight retention, long-term obesity for the woman and her children. Conversely, adverse outcomes resulting from weight gain below recommendation could potentially include preterm births, increased rates of neonatal intensive care admission, and newborn morbidity and mortality. Previous studies indicate the need for healthcare providers to help women gain within the …

Delirium Rate And Risk Factors In Palliative Care Outpatients And Caregiver Coping Strategies, Sarah Deur Livermore Phd, Fnp

Dissertations

Background: Delirium causes suffering and in terminal illness undermines important goals to die at home. Improved knowledge about delirium among palliative outpatients can lead to improved patient outcomes through early identification and treatment in the home. Conversely, a missed diagnosis leads to costly hospital admissions, and is the most common reason to seek long-term care placement (Breitbart & Alici, 2008). Medicare stresses the importance by listing it as a common cause of falls among non-reimbursed hospital events. Prior evaluation of outpatient delirium rate was 14% among demented community dwelling elders (Steis, Evans, et al., 2012a). It is hypothesized that frail, …

Is Combat Exposure Predictive Of Higher Preoperative Stress In Military Members?, Eric J. Bopp Phd

Dissertations

Since September 11, 2001, the United States has been engaged in large-scale combat operations exposing numerous military service members to stressful, traumatic, and threatening environments. As a result, many of these individuals have experienced significant psychological problems, such as anxiety, depression, and posttraumatic stress disorder (PTSD), as well as physiological alterations, such as cardiovascular changes and neuroendocrine disturbances. The preoperative experience may be perceived as stressful, often increasing in magnitude as the patient progresses through the preoperative period. Military anesthesia providers frequently provide anesthetic care to military members with a history of combat exposure. Anecdotally, it is not uncommon for …

Comparing Factors Of Bachelor's Degree Attainment For First And Continuing Generation Students, Holly Gilbertson Hoffman Phd

Dissertations

Colleges and universities have recently been under great pressure to increase institutional graduation rates, due to a surge in consumer demand for accountability and the use of graduation rates to deter nine effectiveness and funding. Many colleges may choose to achieve higher graduation rates by simply increasing selectivity. However, this strategy has the potential to exclude at-risk student populations, namely first generation students, who lack a family track record of college completion and have been shown to be less likely to graduate than continuing generation students. To allow for continued access for first generation students, institutions have the ability to …

Convergence Or Divergence Of Values? A Comparison Case Study Of Teacher Credentialing Programs, Rachel Homel Rice Phd

Dissertations

Educational commentators have long debated whether or not public school teaching is a profession. The definition of a profession is commonly anchored in Andrew Abbott's criteria, which include knowledge (specialized and academic), jurisdiction (diagnosis, treatment, professional inference), and control (ethics, professional organizations, licensure). Teachers in most states need to complete credentialing programs to be licensed. The purpose of this study was to explore what teacher credentialing programs at three diverse universities are doing to build teaching as a profession. The guiding research questions were: (1) What is the relationship between teacher credentialing programs and the professionalization of teaching? (2) What …

The Relationship Between Perceived Academic Self-Efficacy, Remediation, And Academic Performance In Pre-Licensure Baccalaureate Nursing Students, Debra Jean Wilson

Dissertations

Nurse educators are faced with the daunting task of preparing students for professional practice as registered nurses. Students who are academically underprepared are often at risk for nursing course failure. There is a lack of consensus in the literature about predictors of success in nursing education. Most nursing education research has focused on the nursing licensure examination as the outcome measure. This focus occurs late in the curriculum and fails to address at-risk students who don’t make it to graduation. Remediation research has also focused on student performance on the licensure examination and interventions are often poorly described, making replication …

Role Of Myd88 Protein In The Maintenance Of Immunological Self-Tolerance: Induction Of Autoimmunity By Salmonella Infection Consequent To Myd88 Deficiency, Jincy Merin Issac

Dissertations

Activation of the innate immune system is a prerequisite for the induction of adaptive immune responses to both infectious and non-infectious agents. Toll-like receptors (TLRs) are a family of proteins important for recognizing pathogen associated molecular patterns. MyD88 is an adaptor molecule whose function is critical in TLR signaling. MyD88-deficient (MyD88-/-) mice exhibit heightened susceptibility to infections, even by attenuated strains of Salmonella enterica serovar Typhimurium. Paradoxically, despite their hypersusceptibility, infected MyD88-/- mice produce elevated serum levels of anti-Salmonella antibodies regardless of the route of infection. This hypergammaglobulinemia was observed with both Th1-driven (IgG2c and IgG3) and Th2-driven (IgG1) antibody …

The Influence Of Bystanders In Subsequent Bullying Behavior, Jenny Lane Morris

Dissertations

Aggression that is targeted towards an individual or a group of individuals who is at a disadvantage to respond is known by several terms in the literature, including bullying, harassment, and mobbing. There has been much interest in this sort of targeted aggression among school-aged children and, therefore, a large body of literature on the topic exists. In adult populations, especially in workplace environments, much research has focused on the respective roles of the victim and bully in this adverse social dynamic, with less information available on the role of the bystander, which has emerged as an important part of …

Self-Determination Theory As A Pedagogical Foundation For Collegiate Physical Activity Courses, Scot Edward Long

Dissertations

Inactivity, obesity and associated medical, social and economic problems are pervasive in contemporary society. Modern science is aware of the preventative role physical activity offers in deterrence of these problems and the benefits physical education offers. Traditionally, physical education has focused primarily on physiological variables; however, physical activity begins with a behavioral change. Motivation is the necessary factor to initiate physical activity and self-determination theory (SDT) can be used to explain learner motivation in the world of collegiate physical education. Institutionalized schooling is typically performed in a controlling nature, which creates a poor environment for learning and motivation. The purpose …

Dissertations

In difficult economic times a healthy employee that has consistently low absenteeism rates and who volunteers or takes on extra responsibilities at the workplace could be an asset for any business or organization. The personnel component is a significant area of expense for most businesses that includes costs related to salaries, insurance, and training. An effective and efficient employee impacts the morale, productivity, and the fiscal health of a workplace. The aim of the present study was to examine the pattern of relationships between organizational citizenship behavior and employee wellness behaviors. Data sets that consist of a combination of a …

The Role Of Glutamate Signalling In Diabetic Neuropathy, Nadia Hussain

Dissertations

The majority of diabetics develop neuropathy, which can be debilitating, but the underlying pathophysiological mechanisms are poorly understood. Diabetic neuropathy progresses in a distal to proximal manner. Previous studies have shown that glutamate, the most common excitatory neurotransmitter, plays a role in the pathogenesis of neuropathy. The reason why the role of glutamate in nociception becomes a problem in diabetes and the mechanisms that are involved are unknown. Based on the preliminary data, the hypothesis was that glutamate pathways are likely to be involved in diabetic neuropathy particularly neuropathic pain. Pathways were investigated to look for changes that might reflect …

Identification Of Novel Natural Compounds With Anti-Breast Cancer Activities, Yusra Saif Al Dhaheri

Dissertations

Breast cancer continues to be the leading cause of cancer-related death in women worldwide. In this dissertation, natural compounds with anti-breast cancer activities were identified. We investigated the effect of Salinomycin, a potassium ionophore isolated from Streptomyces albus, on the survival of three human breast cancer cell lines MCF-7, T47D and MDA-MB-231. High concentrations of Salinomycin induced a G2 arrest, down regulation of survivin and triggered apoptosis. Interestingly, treatments with low concentrations of Salinomycin induced a transient G1 arrest at an earlier time and G2 arrest and senescence, associated with enlarged cell morphology, at a later time. There was also …

Effects Of The Endocannabinoid Anandamide On Excitability And Calcium Signaling In Rat Ventricular Myocytes, Lina Tareq Al-Kury
