Nuclear Pariahs And Regimes In The New World Disorder, Wayne F. Lesperance Jr.

Graduate Program in International Studies Theses & Dissertations

This thesis discusses the role of pariah states vis-a-vis the nonproliferation regime. Specifically, the foreign policy of the Islamic Republic of Iran (IRI) is analyzed to determine, first, whether Iran is a pariah, second, the potential threat the IRI poses to the Persian Gulf region and third, the possible international responses that may be undertaken to address Iranian pariahtude in the nuclear field. Through the course of this thesis regimes are defined as a set of implicit and explicit rules, principles, norms, and decision-making procedures around which actor's expectations converge and which govern relations among states. Pariahs are defined as …

Characterization Of P39, A Borrelia Burgdorferi Specific Protein, Jill M. Troyer

Theses and Dissertations in Biomedical Sciences

Borrelia burgdorferi, the causative agent of Lyme disease, expresses a species specific, 39 kiloDalton protein of unknown function called P39. This protein is highly immunogenic and the presence of anti-P39 antibodies in patient sera is used as an indicator of B. burgdorferi infection. P39 is also a candidate for vaccine developement due to conserved expression of P39 among B. burgdorferi isolates. Since little is presently known about this important molecule, the present study was designed to characterize P39 and was carried out in six separate investigations. First, infectious and noninfectious isolates of B. burgdorferi were established in vitro, and …

The Diet Of Oryzomys Palustris Based On Stomach Content Analysis, Shannon L. Wright

Biological Sciences Theses & Dissertations

Oryzomys palustris (Harlan) is unusual in that it is one of two carnivorous mammals in the Family Muridae in North America. A diet analysis of Oryzomys palustris. the marsh rice rat, was done based on stomach contents. This was accomplished by taking the animals from two study areas located on the Eastern Shore of Virginia. The animals were taken monthly for one year. Once caught, the animals were sacrificed and their stomach contents were identified to the lowest taxonomic level possible. This study showed that rice rats were omnivorous mammals, eating a variety of foods, including dicots, monocots, crabs, …

Passage Or Pathology: Current Attitudes Toward Women's Aging In The Literature Of Menopause, Kaaren Gearhart Ancarrow

Institute for the Humanities Theses

Menopause is currently portrayed in the medical literature as a pathological 11 process resulting from "hormone deficiency." However, feminist writers contend that the climacteric is part of the normal female aging process and oppose the medicalization of menopause and the consequent inevitable hormone replacement therapy (HR T) promoted by the hegemonic medical and pharmaceutical industries. This paper explores the historical development of these two paradigms of menopause and their manifestations in samples of three classes of contemporary literature on the subject: gynecological textbooks, popular advice books written by physicians, and women's accounts. Five major themes are investigated using quantitative and …

To demonstrate the applicability of the paradigm, a …

Depositional Environment And Sequence Stratigraphic Interpretation Of Miocene St. Marys Formation, Calvert County, Maryland, John J. Blandin

OES Theses and Dissertations

The Miocene St. Marys Formation at Calvert Cliffs, Maryland is divided into four depositional packages made up of marine fades representing shallow shelf through intertidal conditions. These depositional packages are separated by five laterally persistent surfaces and were defined based on detailed depositional fades analysis of 24 measured sections, averaging 17 meters thick. These four packages make up two marine sequences, stratigraphic units bound above and below by surfaces of sea level fall. The lower sequence is composed of a single depositional package, while the upper sequence is composed of three upward-shallowing depositional packages (i.e. para-sequences). A fifth depositional package …

Downsizing America In The Twentieth Century: A Sociological And Theoretical Analysis Of The Shrinking Middle Class, Terreea Lynne Adams

Institute for the Humanities Theses

Downsizing is the process by which a firm decreases its number of employees, even during times of a strong economy, with the stated purpose of generating greater efficiency, productivity and of course, profit. The downsizing trend in the United States during the past three decades has resulted in an enormous shift in the structure of our society. Various theorists, sociologists and economists employ differing ways of looking at this downsizing trend and its effects on the largest segment of the population; that is, the middle class.

lndications of a healthy economy are low levels of unemployment and poverty-. Downsizing involves …

An Investigation Of Software Reliability Models, Pamela Elaine Bowman

Computer Science Theses & Dissertations

Many software reliability models have been promoted in the literature in an attempt to provide a meaningful response to the growing need to know the reliability of software during and after the development process. However, there are well-founded concerns as to the accuracy of the individual model, as well as to the choice of which model to use for a particular program. A recent experiment based on the debugging history of a partially debugged program used a gold version to label a debugging graph from replicated data. This experiment concluded that presenting the replicated data to the models in a …

Telemedicine: Discovering And Overcoming The Barriers, Dennis Mcclain-Furmanski

Community & Environmental Health Theses & Dissertations

Information Warfare: Technology And The Information Advantage, Daniel Matthew Parker

Graduate Program in International Studies Theses & Dissertations

This thesis analyzes information warfare--that emerging form of warfare that attempts to destroy, degrade and exploit the information systems of another, while protecting one's own--in the context of the technology of warfare. Just as one might peel an onion, the analysis proceeds from a general analysis of technology in warfare to the more specific analysis of information warfare as it is currently defined. Information technology is an enabling factor in the emergence of information warfare as a new warfare area. Although it is revolutionizing the way warfare is conducted, the elements of information warfare have been practiced for thousands of …

Theses and Dissertations in Urban Services - Urban Management

This study is a comparative analysis of the structure, organization and activities of the nine non-profit (501 (c)(3)) mediation centers for the resolution of dispute (CDRC) in Virginia. Data for the analysis was collected through on-site interviews, in-depth case studies, and discussions with the leadership of the centers.

The CDRCs suffer from funding shortfalls which pressure them to shift their attention away from their mission. They are dependent upon the state's court contracts for mediation services in order to financially supplement their pro bono mediations and to generate operating capital. The large-budget CDRCs provide a considerable number of pro bono …

Determinants Of Ceo Pay: A Critical Assessment, W. Otto Carroll

Theses and Dissertations in Business Administration

This research expands the study of determinants of CEO pay. Previous studies have found conflicting results regarding the importance of firm size and firm performance in influencing the amount of CEO compensation. Other studies are incomplete with respect to the measurement of both executive pay and its determinants. Traditional theories of executive compensation such as equity theory, expectancy theory, human capital and labor market theory provide the starting point for determinants of CEO pay. However, to more fully understand these determinants, the model includes a test of agency theory showing the relationship between board control and pay. It tests the …

The United State Government Versus John Harrison Surratt: A Study In Attitudes, Thomas Michael Martin

History Theses & Dissertations

Fear Of Crime In Rural America: Fear Along Virginia's Eastern Shore, David Steven Simon

Sociology & Criminal Justice Theses & Dissertations

Using 1996 Survey data collected from residents along Virginia's Eastern Shore, this study addresses fear of crime in rural communities. Most prior research has focused on fear of crime in urban communities or has reported a relatively low fear of crime in rural communities. However, some recent analyses have indicated unusually high fear in small towns experiencing rapid population growth and economic changes. Heightened fear of crime has been observed even where there has been no apparent increase in criminal victimization experiences. This study addresses fear of crime and its relation to perceived risk of victimization, density of acquaintanceship, community …

Comprehensive Conjunctive-Use Management Of Connected Surface Water Groundwater Systems Using Stochastic Inputs And Uncertainties, Seshadri Suryanarayana

Civil & Environmental Engineering Theses & Dissertations

A comprehensive conjunctive-use management model is developed. The dynamics of flow and solute transport processes in connected surface water groundwater systems are integrated by a dual programming management model. The governing aquifer flow parameters and streamflows are treated as stochastic random processes. Multiple realizations of the random field are generated and are explicitly incorporated in a non-linear optimization model along with other system, environmental, and management constraints. To facilitate management of large aquifer systems, a linked simulation-optimization approach is used. The simulation program generates the response matrices for flow and transport processes. The management model then determines optimal well discharges …

Optimality And Construction Of Designs With Generalized Group Divisible Structure, Sudesh K. Srivastav

Mathematics & Statistics Theses & Dissertations

This thesis is an investigation of the optimality and construction problems attendant to the assignment of v treatments to experimental units in b blocks of size k, paying special attention to settings for which equal replication of the treatments is not possible. The model is that of one way elimination of heterogeneity, in which the expectation of an observation on treatment i in block j is T_i + βj (treatment effect + block effect), where T_i and βj are unknown constants, 1 ≤ i ≤ v and 1 ≤ j ≤ b. All observations are assumed to …

Development Of The Inventory Of Life Span Events, Julie A. Dickison

Psychology Theses & Dissertations

The possible relationship between stressful life events and subsequent illness has been studied in the past few decades, resulting in several widely-used questionnaires. However, these measures tend to focus on recent events and attempt to remove subjective rating of a stressful event by the respondent. These two factors may limit these scales clinical utility. An alternative measure, the Inventory of Life Span Events (ILSE) is proposed, to quantify the life-stress burden for childhood, adolescence, adulthood, and across the entire life span. ILSE was compared to other leading measures for life events, hassles and perceived stress, and was more closely related …

Lead Activation Of A Developmentally Regulated Calcium Channel In Rat Hippocampal Nerve Terminals, Troy E. Rhodes

Theses and Dissertations in Biomedical Sciences

Low level lead (Pb²⁺) exposure may produce lasting deficits in learning and memory by altering calcium (Ca²⁺) dependent processes. Isolated presynaptic nerve terminals from rat hippocampus were loaded with the intracellular (Ca²⁺) indicator Fura-2. The changes in cytoplasmic free calcium ([Ca²⁺]_i) were measured by stopped-flow fluorescence spectroscopy following depolarization with elevated potassium on a millisecond time scale (Lentzner et al., 1992). Depolarization promoted a rapid increase in Ca²⁺_i which occured in two kinetically distinguishable phases: a fast component, representing the activity of rapidly inactivating Ca²⁺ channels (τ …
