Circadian Disruptions In Night Nurses, Leah Swenson

Theses and Dissertations

A lack of knowledge exists in the physical and psychological impact shift work, particularly working during the night shift, causes in nurses. Inadequate rest derived from night shift work seriously affects the frontal cortex's ability to control speech, access memory, and solve problems. It has been well documented that night shift workers sleep less, perform less effectively on psychomotor and cognitive tests, make more errors during night shifts, and are at higher risk for motor vehicle accidents because of post-night shift drowsiness. Planned naps in the workplace may be an effective intervention to some of these adverse circumstances

Rural Breastfeeding Mothers: Five Reasons For Early Cessation, Amy L. Suda

Theses and Dissertations

Breastfeeding remains the most natural, convenient, and recommended source of early feeding for newborns. Unfortunately, more women are having potentially preventable problems in the first few weeks after birth which may lead to early cessation of breastfeeding. In the rural area, quick and accessible resources for questions are often hard to come by, leading to the termination of the breastfeeding relationship. This earlier than expected termination may lead to feelings of disappointment, frustration and sadness by the already overburdened new mother. The goal of this project was to identify five common reasons for discontinuation of breastfeeding in the early weeks …

The Role Of Perceptions Of Female Administrators Regarding The Gender Regimes In Urban Co-Educational Secondary Schools In Uganda, Frances Naluwemba

Theses and Dissertations

Leaders and policy makers in Uganda developed a national strategy of placing female administrators in traditionally male-dominated coeducational secondary schools in the belief that their vision would promote equitable education by changing gender regimes that play in schools. Gender regimes are patterns of gender arrangements that could disadvantage the education of boys or girls (Connell, 2002). The purpose of this study was to discover if female administrators perceived and had developed strategies to change gender regimes in their schools. Participants were 13 female administrators of government-supported coeducational mixed/day secondary schools in Kampala and Wakiso urban districts. Participants ranged in age …

Spirituality And Religious Support As Buffers Against The Negative Effects Of Marital Distress On Ambulatory Blood Pressure, John Dale Livingstone

Theses and Dissertations

The beneficial effects of religion and spiritual factors on cardiovascular functioning have become an area of increasing research. Similarly, considerable research has also investigated the negative effects of marital distress on cardiovascular functioning. Little is known, however, about potential protective factors against the deleterious effects of marital distress on cardiovascular functioning. Social support has been identified as a potential buffer against the negative effects of marital distress on ambulatory blood pressure, and the current study hypothesized that spirituality, religiosity, and religious support would also buffer the negative effects of marital distress on ambulatory blood pressure. Fifty-eight married couples were recruited …

The Effects Of A Resveratrol Derivative On Regulatory Behaviors And Reproductive Health In Male And Female Long-Evans Rats, Kimberly Michelle Fabick

Theses and Dissertations

Phytoestrogens are chemicals produced by plants that act like estrogens and have the ability to bind to the mammalian estrogen receptor system. The purpose of this study is to evaluate a new phytoestrogen analog called 4-acetoxy Resveratrol. Resveratrol is a phytoestrogen that has been found in the skin of grapes. Resveratrol has been shown to be able to bind to the estrogen receptors and has a similar molecular structure as estradiol.

The Effects Of Prenatally Administered Phytoestrogens On The Reproductive And Behavioral Development Of Long-Evans Rats, Crystal Blake

Theses and Dissertations

Equol is known to be a selective androgen modulator and has the ability to bind and inhibit 5-alpha dihydrotestosterone (5α-DHT). Equol is also a selective estrogen receptor modulator and is able to bind beta estrogen receptors with high affinity. As estrogen receptors are found in the hypothalamus, pituitary, and gonads, prenatally administered equol could affect the morphological and reproductive development of offspring. To test this hypothesis, during gestational days 14 to 20, forty-two pregnant Long-Evans rats were given one of six treatments: 1) no treatment, 2) injection with dimethyl sulfoxide (DMSO), 3) injection with 10 mg/kg equol, 4) injection with …

A Comparison Of Ordinary Least Squares And Instrumental Variables Regression For High Intensity Disease Management Evaluation, Gerald A. Craver

Theses and Dissertations

Purpose: Disease management (DM) programs are typically evaluated using study designs that are susceptible to selection bias and other internal validity threats because participants are often allowed to self-select into the programs. As a result, DM evaluation results are usually biased because researchers are unable to control for preexisting differences between the DM participants and non-participants. Linden and Adams (2006) offer an instrumental variables (IV) regression procedure as a means of deriving unbiased estimates of DM program effectiveness. However, IV regression relies upon the existence of one or more variables (or instruments) that produce considerable variation in the program participation …
