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 …

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 …

Measuring Organizational Climate For Diversity, Amy L. Vick

Psychology Theses & Dissertations

The Climate for Diversity Index measures three dimensions associated with the ability of organizations or units to create an environment that allows members of all sociocultural backgrounds to participate and fully develop. The climate for diversity impacts individual outcomes such as general job satisfaction, affective commitment, identification with a psychological group/department, organizational citizenship behavior, and the intent to turnover. Several structural models depicting the relationship between the climate for diversity and the individual outcome variables were examined. Significant differences in perceptions of the climate for diversity are predicted by ethnicity, disability, and position. Data were provided by 319 members of …

Real-Time Visual Speech Articulation Training Aid, Neiyer S. Correal

Electrical & Computer Engineering Theses & Dissertations

A real-time visual articulation training aid has been implemented. It provides instantaneous visual feedback of vowel and stop-consonant production on a computer screen. The vowel training system corresponds to an improved floating-point implementation of a previous fixed-point system developed by Beck (1992). The new implementation provides better accuracy and an approximate five-fold increase in speed. Acoustic features computed from global short-time spectral shape are used for classification of vowels. Temporal spectral trajectories timed to begin with burst onset are used for stop consonants. A neural network is used to transform measurements of auditory stimuli from the feature space to a …

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 …

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 …

Representations Of Gender In Juvenile Literature During The Era Of The American Revolution, Sandra Strohhofer Pryor

History Theses & Dissertations

This study investigates representations of gender in fiction during the era of the American Revolution. Literature has an important role in creating and responding to cultural values, as well as in conveying ideologies. Through analysis of fictional stories for children, the simultaneous presence of themes of gender, religion, liberalism, and republicanism will be documented. Children's stories from England were reprinted in America after the Revolution. The continuity between late nineteenth century American success narratives and their early eighteenth century British precursors, as well as their gendered nature, will be demonstrated.

American fiction of the late eighteenth century foreshadowed both the …

An Analysis Of Structure, Organization, And Activities Of Community Dispute Resolution Centers In Virginia, Terri Colby Barr

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 …

Grading Teaching: An Evaluation Of Teaching Techniques Used By California Community College Introduction To Sociology Instructors, Lynette Ann Osborne-Estes

Sociology & Criminal Justice Theses & Dissertations

Research on teaching techniques used in higher education report that instructors who use a mixed repertoire of styles promote optimal student learning. However, previous research also indicates that many college professors continue to use the less effective traditional lecture instead of implementing more student-centered methods of instruction. This thesis investigates two general research questions. (1) To what extent do community college instructors utilize teaching techniques that have been shown to promote optimal student learning? (2) What factors, if any, increase the probability of an instructor using the teaching techniques that promote optimal student learning? In order to address these questions …

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 …

Application Of Monoclonal Antibodies Against Creatine Kinase Mm And Bb Isoenzymes For Creatine Kinase Mb Isoenzyme Detection, Lei-Chieh Chuang

Chemistry & Biochemistry Theses & Dissertations

Nondiagnostic ECGs and unknown characteristic chest pains increase the diIIiculty of Acute Myocardial Infarction (AMI) diagnosis. Biochemical markers, such as creatine kinase MB isoenzymes (CK-MB) and myoglobin, are employed for the early detection of AMI. Compared to myoglobin, CK-MB reveals a higher specific indicator for AMI detection owing to its abundance in cardiac tissue. Hence, a successful CK-MB detection is expected to improve AMI diagnosis and therapy.

A CK-MB detecting ELISA system was set up based on a sandwich assay principle by using specific CK-B and CK-M monoclonal antibodies. The dimeric nature of the CK-MB isoenzyme provides two epitopes on …

Reactions Of Aqueous Chlorine With Alanylphenylalanine In Model Solutions And In A Wastewater, Thomas C. Fox

Chemistry & Biochemistry Theses & Dissertations

Model solutions of the dipeptide alanylphenylalanine were chlorinated to four different chlorine-to-amino nitrogen (Cl₂/Ala-Phe) mole ratios and analyzed by high performance liquid chromatography. At mole ratios ≤ 1, N-chloroalanylphenylalanine was the only major product. As the Cl₂/Ala-Phe mole ratio was increased to ≥ 2, N,N-dichloroalanylphenylalanine was the only major product. In model solutions (pH 7.0) the dichlorinated dipeptide decomposed (t_1/2= 4.1 hr) to form a stable N-chloroketimine, which has a half-life of 125 hours. This N-chloroketimine then decomposed to form phenylalanine.

To follow these reactions in a wastewater, alanyl-p-[ …

The Influence Of Time Pressure And Information Load On Rule-Based Decision-Making Performance, Brooke Browne Schaab

Psychology Theses & Dissertations

Performance was evaluated under varying levels of time pressure and information load to determine their influence on simple rule-based decision-making. Consistent errors, biases, and heuristics found in human decision-making have been attributed to attempts to reduce attentional demands and to the limitations of working memory. Do these same mistakes occur when little or no demand is placed on working memory and the decision is made by following a set of simple rules? Using a simulation of a radar operator's task, 96 participants monitored a display for 24 min. Time pressure was manipulated by increasing or decreasing the number of aircraft …
