Critique Of The Wigner Tunneling Speed And A Proposed Alternative, P Krekora, Q Su, Rainer Grobe

Faculty publications – Physics

In the context of superluminal propagation of wave packets through potential barriers, the tunneling speed is usually characterized by the Wigner velocity. We propose an alternative speed that takes into account the interference between the incoming and the reflected waves and leads to a better estimation of arrival time for a wave packet entering the tunneling region. This arrival time is derived by an extrapolation from inside the barrier. The analytical theory is based on the stationary phase approximation whose validity is justified by a comparison with the numerical solution of the time-dependent Dirac equation.

Facilitators And Barriers To Initiation Of Hormone Replacement Therapy By Nephrology Health Care Providers, Lynn Tramel

MSN Research Projects

Cardiovascular disease, osteoporosis, and dementia are three disease processes that have been directly linked to estrogen deficiency. Cardiovascular disease (CVD) is the number one cause of death for all postmenopausal women, including those with end-stage renal disease (ESRD). Osteoporosis and dementia are disease processes that profoundly affect the quality of life for postmenopausal women. Currently, 34% of women in the general population receive hormone replacement therapy (HRT), while only 10% of women with ESRD receive this therapy. Therefore, the purpose of this descriptive study was to examine the facilitators and barriers of nephrology health care providers to initiation of HRT …

Knowledge Levels Of College Students Concerning Folic Acid, Lesa Faye Ferguson

MSN Research Projects

Neural tube defects (NTDs) are among the most serious birth defects affecting approximately 4,000 pregnancies in the United States each year. More than one third of these pregnancies are spontaneously aborted. Thus, about 2,500 infants per year are born with an NTD. Research spanning two decades has shown that women who consume folic acid- containing supplements have 50% to 75% fewer infants with NTDs than women who do not consume folic acid supplements. Despite the empirical evidence in the literature, the message about folic acid is not getting across to the general public. This quasi-experimental pretest-posttest study examined the impact …

Adherence To Jnc Vi Guidelines For Hypertension Management By Primary Care Nurse Practitioners, Gregory N. Cagle

MSN Research Projects

Although improvement in the detection and treatment of hypertension has occurred over the last two decades, the trends have stagnated over the last 5 years with a related increase in mortality from cardiac failure and an increased incidence of end-stage renal disease. Current researchers have made a strong argument that many health care providers have not been successfully managing hypertension at a level, as established by research, to prevent target organ disease over time. As health care providers, family nurse practitioners (FNPs) and adult nurse practitioners (ANPs) are managing hypertension in outpatient settings as primary care nurse practitioners (PCNPs). This …

Rural Elders' Knowledge Of Nurse Practitioners As Health Care Providers, Tim Watson

MSN Research Projects

The population of America is growing older every year. Thirteen percent of the population is at least 65 years old. Many elders have limited health care choices because fewer physicians are locating their practices in rural areas. Nurse practitioners are now practicing in underserved areas such as rural communities. The purpose of this descriptive exploratory study was to explore baseline knowledge of rural elders concerning the role of nurse practitioners as health care providers. Becker's Health Belief Model was used to guide the research. The research question was as follows: What is rural elders' knowledge of nurse practitioners as health …

Preconception Health Care Practices Of Nurse Practitioners In The Primary Care Setting, Charlotte Anne Williams

MSN Research Projects

The United States Public Health Service recommends that age appropriate preconception care be provided to all women of reproductive age. Preconception health care provides a woman the opportunity to assess her health status before pregnancy, make appropriate health promoting behavior changes and increase the potential for a healthy pregnancy outcome. Neural tube defects, fetal alcohol syndrome, congenital malformations and low birth weight are examples of adverse infant conditions that can be reduced through preconception health care interventions. Current research suggests that preconception health care according to United States Public Health Service recommendations is not practiced in the primary care setting. …

Outcomes Of An Abstinence Education Program On The Perceptions Of Risks And Intentions About Sexual Activity Among Eighth-Grade Students, Cindy Holcomb

MSN Research Projects

The rate of teenage sexual involvement is at an all-time high. Traditional sex education is obviously not working. Abstinence education programs have been initiated within some school districts in an effort to decrease the number of adolescent pregnancies and sexually transmitted diseases. The purpose of this quasi-experimental study was to investigate the perceptions of risks and intentions of sexual activity in eighth-grade students before and after an abstinence education program. Pender's Health Promotion Model was utilized as the theoretical framework for this research. Two null hypotheses were used throughout this study. The first hypothesis stated that there would be no …

The Impact Of Boot Camps And Traditional Institutions On Juvenile Residents: Perceptions, Adjustment, And Change, Doris Layton Mackenzie, David B. Wilson, Gaylene Armstrong, Angela Gover

Criminology and Criminal Justice Faculty Publications

Experiences of 2,668 juveniles in 26 boot camps were compared to 1,848 juveniles in 22 traditional facilities. There were no reported differences between juveniles' anxiety and depression in the two types of facilities during their first month of confinement. Overall, juveniles in boot camps perceived their environment to be more positive (i.e., therapeutic), less hostile (i.e., dangerous), and as providing less freedom (conversely more structure) than juveniles in traditional facilities. Relative to others in the same facility, youth who viewed their facility negatively experienced more stress (i.e., anxiety, depression). Scales measuring changes over time found that youth in boot camps …

Does The Ethiopian In The Diaspora Have A Role In Ethiopia’S Development?, Temesghen Hailu

International Conference on African Development Archives

Ethiopia is one of the economically poor nations in the world. It doesn’t take effort to identify what economic and social problem characterizes our country. Underemployment, malnutrition, subsistence farming, deforestation, erosion, poor transport and telecommunication services, inadequate access to drinking water and health care, high mortality and birth rates, low life expectancy, etc. All these are recipes of what can be considered as individuals living below poverty line, however specific it may be defined. A host of problems face our country. The solution, therefore become complicated because strategies to solve one problem may accelerates others. These problems are the result …

The Eprdf And The Crisis Of The Ethiopian State, Aregawi Berhe

International Conference on African Development Archives

Present day Ethiopia constitutes a multi-ethnic society where ethnic politics and ethnic mobilization had been the path to power and the pillars to maintain it, perceptibly since the Era of Princes (1769-1855). During that period, Ethiopia was parcelled or ‘decentralized’ in disorderly fashion among local princes, who drew support from their ethnic or sub-ethnic base. To this day, ethnic grounds have been the power base of Ethiopian political elites under various banners and forms.

Ethiopia is now facing yet another experimental policy under the autocratic regime of the Ethiopian People’s Revolutionary Democratic Front (EPRDF) whose core element is the Tigray …

Decision Making On Manure Use And Fallowing As Soil Fertility Maintenance Techniques In The Northern Highlands Of Ethiopia: The Case Of Ankober District, Senait Regassa

International Conference on African Development Archives

Degradation of the highly scarce agricultural resource, land, has been one of the notorious problems in Ethiopia. One form of degradation of land resource is soil nutrient depletion. Manure application as a source of major plant nutrients contributes to managing land resources towards sustainability through the improvement of physico-chemical properties of the soil. Fallowing too, allows for natural regeneration of the soil. However, decisions on how to manage the land are ultimately made by farmers and their decision-making process is influenced by several factors. This paper attempts to examine the effects of some important farm, family and institutional variables on …

Community Resource Management: The Case Of Grazing Lands In Northern Ethiopia, Berhanu Gebremedhin, John Pender, Girmay Tesfay

International Conference on African Development Archives

Communal grazing lands are important sources of livestock feed in developing countries (ILRI, 1998). In the presence of sufficient demand for livestock or livestock products, unrestricted access to the grazing lands will result in overexploitation of the resource and the scarcity rent of the resource remains unappropriated. Each individual user of the resource enjoys the full benefit of her use of the resource but bears only a fractional part of the cost. As a result, the traditional uncontrolled and free grazing system in many developing countries has caused severe degradation of the grazing lands.

Determinants Of Farmer Perceptions Of The Severity And Yield Impact Of Soil Erosion: Evidence From Northern Ethiopia, Berhanu Gebremedhin, Scott Swinton

International Conference on African Development Archives

Farmers must perceive soil erosion as a problem before they will invest in preventing it. However, perceptions are often overlooked in the conservation literature. This study analyzes the levels and determinants of farmer perceptions of soil erosion in northern Ethiopia. Results are based on a survey of 250 farmers managing 900 fields during the 1995-96 cropping season. Farmer perceptions of the severity and productivity impact of soil erosion were measured at plot level as ordinal variables. Ordered probit and ordinary probit statistical regressions were used to analyze the levels and determinants of farmer perceptions.

Farmers were more likely both to …

Economic Reforms And Structural Changes In Ethiopia Since 1992; An Inquiry, Prabhakar Reddy Tada

International Conference on African Development Archives

Since the beginning of the nineties, Ethiopia has been experiencing significant political, economic and social changes. Despite the efforts of the Ethiopian government to strengthen market economy mechanisms and to decentralize and regionalize decision making structures, the country is still facing a number of problems such as poverty, soil degradation, regional conflicts etc. The elaboration of sound development strategies is essential to promote economic growth, and to alleviate poverty in the context of limited resources. In brief, the economy is undergoing the process of transformation in all most all the fields. In this context, the paper is an attempt to …
