The Ottoman Navy 1900-1918 : A Study Of The Material Personnel And Professional Development Of The Ottoman Navy From 1900 Through The Italian, Balkan, And First World Wars., Karl Wilhelm Augustus Darr

Electronic Theses and Dissertations

As seafaring states evolve into nations and nations into empires, the power that protects such maturation is seapower. Geographic isolation via deserts or seas can obtain time for political and social evolution. However, only a formidable naval presence can ensure external security in order that internal reforms take root. No major modern power has survived without an adequate indigenous navy. This doctrine holds true especially in reviewing the navy of the Ottoman Empire in the early twentieth century.

In this thesis, l show that the absence of tangible fleet units cost the Ottoman Empire not only the peripheries of the …

Quantal Mechanisms Underlying Stimulation-Induced Augmentation And Potentiation, Hong Cheng

Electronic Theses and Dissertations

Repetitive stimulation of motor nerves causes an increase in the number of packets of transmitter ("quanta") that can be released in the ensuing period. This represents a type of conditioning, in which synaptic transmission may be enhanced by prior activity. Despite many studies of this phenomenon, there have been no investigations of the quantal mechanisms underlying these events, due to the rapid changes in transmitter output and the short time periods involved. To examine this problem, a method was developed in which estimates of the quantal release parameters could be obtained over very brief periods (3 s). Conventional microelectrode techniques …

Tnf(Alpha)-Dependent And Tnf(Alpha)-Independent Activation Of Macrophage Effector Function, Annette R. Clemons-Miller

Electronic Theses and Dissertations

Tumor necrosis factor α (TNFα) is a pleiotropic cytokine that is predominantly produced by activated macrophages. The effects of TNFα are as diverse as the cells with which it interacts, e.g., stimulating fibroblast growth, exerting cytotoxic/cytostatic; activity against various human and murine cell lines, promoting inflammation through upregulation of endothelial adhesion molecules and IL-8 production. Yet TNFα is best known, and in fact was originally described, for its role in the bacterial-induced hemorrhagic necrosis of tumors and exacerbation of septic shock in which aberrant TNFα production leads to vascular collapse, cachexia, multiple organ failure, and ultimately death in as many …

A Comparison Of Teacher-Directed Versus Self-Directed Learning Preferences Of Students At Five Selected Community Colleges: Exploring The Relationships Among Age, Gender, And Academic Majors, Huiming Wang

Electronic Theses and Dissertations

One of the major priorities for community colleges is to focus on the pedagogical tools that will allow students to achieve excellence and quality in curriculum and instruction to meet the changing societal needs (Shearon & Tollefson, 1989). Rapid demographic, social, and technological changes demand that community colleges produce self-directed lifelong learners (Closson, 1996). The study of student learning preferences for more teacher-directed or more self-directed learning is one of the concepts that is important in enhancing teaching and learning practices. The purpose of this study was to examine students' teacher-directed versus self-directed learning preferences in specific courses. The possible …

The Relationship Between Rural Low-Income Women's Knowledge And Short-Term Duration Of Breastfeeding, Jefferey J.A. Enstad

Electronic Theses and Dissertations

Although patterns of breastfeeding initiation and duration among American women have made dramatic changes over the past 100 years, these patterns have not been studied in rural, low-income women. Furthermore, even less is known about the characteristics of rural low-income women who practice short-term breastfeeding. Therefore, the problem under investigation was to explore the relationship between rural low-income women's knowledge and short-term duration of breastfeeding. The objectives of the study were to: 1) describe what are the characteristics of rural low-income women who breastfeed for four or more weeks postpartum, 2) describe what sources did they receive breastfeeding instruction and …

Electronic Theses and Dissertations

The purpose of this descriptive study was to examine differences in depressive symptomology and perceived body image in postmenopausal women who currently used HRT with women who never used HRT and women who had previously used HRT but were currently not. Few medical treatments presently available for postmenopausal and menopausal women have such substantial benefits, and risks, as hormone replacement therapy (HRT). The study is based on findings that document the use of HRT in preventing chronic illnesses that afflict elderly women. Chronic illness and disability has been shown to increase the incidence of depression in the general population. Chronic …

Effects Of Temperature, Water Hardness, And Recirculation On Copper Corrosion, Brian R. Weiss

Electronic Theses and Dissertations

In previous work, the effects of water quality have been shown to influence the formation of scale from copper corrosion. A general understanding of the effects of water quality on copper corrosion have been difficult to obtain because of complex interactions of water quality variables on copper corrosion in different water supply systems. The objective of this study was to examine the effects of temperature and water hardness on copper corrosion occurring in a household water supply system. The effects of recirculation were also studied in concurrence with the above water quality parameters. Electrochemical corrosion testing and corrosion by -product …

A Comparison Of Adolescent Drug Use Between Urban And Rural Populations, Randall G. Rhodes

Electronic Theses and Dissertations

Prior research has found extensive levels of drug use among the adolescent population from standard metropolitan statistical areas. The reviestudies show high drug use rates in the urban minority population, particularly in regards to cocaine use. Also, arrestee data examining law violations compared to drug usage and the age of initial usage correlates to the onset of delinquent behavior in the juvenile population. There are relatively few studies that have examined rural populations in regards to drug usage rates in comparison to urban populations. This study compares, through descriptive statistical analysis, arrestee data from the rural adolescent population of Cape …
