Vibrations Of Maroons And Marronage In Caribbean History And Archaelogy, E. Kofi Agorsah

Black Studies Faculty Publications and Presentations

A discussion of the phenomenon of "resistance" as an important element in the shaping of the History of the New World, and the geographical distribution of Maroon resistance groups in the Caribbean and adjoining areas, introduces this paper. It is contended that historical and ethnographic evidence fail to adequately present the true picture of Maroon culture, considered as a only most important element that brings others together in a coherent way. Using evidence from Jamaica, it is illustrated that filling in the existing gap in our knowledge about Maroons and marronage as well as identification of cultural continuities and discontinuities, …

Pretrial Release In Criminal Courts: A Study Of Three Oregon Counties, Melvin Earl Degraw

Dissertations and Theses

Pretrial release (PTR) is the permanent or temporary freedom from incarceration for criminal defendants awaiting adjudication of their cases in court. From Anglo Saxon times in England, people accused of non-capital crimes were generally permitted to remain free until judicial officials could hear the charges against them. In America, pretrial release has been advocated by the courts since the colonial era. The U. S. Constitution requires that bail not be excessive, but leaves governments free to decide how bail laws are administered. The study briefly traces the historical developments of PTR up to the present time. The study then centers …

Social Support In An Urban Moroccan Neighborhood: The Effects Of Social Networks, Mediation And Patronage On The Physical Health And Psychological Adjustment Of Women, Carla Ann Green

Dissertations and Theses

Although there has been a great deal of research in the areas of social networks, social support and well-being over the past two decades, little of that research has been cross-cultural, and virtually none has been carried out in countries outside the West. The present study attempted to describe the structure and functioning of the social networks of a group of relatively modern urban Moroccan women, and the associations among their social networks, social support, physical health and psychological well-being. Extensive interviews were conducted with 108 married or previously-married women who were living in a middle-class neighborhood in Rabat, Morocco. …

Identifying Factors That Influence Perceptions Of Teacher Efficacy As A Means Of Building Capacity For Restructuring Schools: A Case Study Approach, Deborah Sommer

Dissertations and Theses

Recent efforts to restructure schools through increased teacher involvement are likely to fail without a corresponding redesign of the underlying organizational and political structure of schools. Because the current structure of most schools actually prohibits the collaboration necessary to effect change and promotes professional isolation instead, staff members faced with the tasks of restructuring experience frustration more often than success. The changes that do occur are often superficial and cosmetic while the basic hierarchy and mechanisms of control remain intact. Allowing teachers to redesign their schools, specifically to develop new models that promote interdependence and the sharing of professional expertise, …

Disequilibrium Transition Of The Consumer Goods Market In China, 1954-1991, Hui Shu

Dissertations and Theses

This is an in-depth study of the structural change and transition of the Chinese consumer goods market from 1954 to 1991 using disequilibrium econometric methodology. The model for the Chinese consumer goods market is based on the Portes-Winter disequilibrium model for centrally planned economies (1980). The demand function is derived from the Houthakker-Taylor savings function. The supply function is composed of approximations to the government's long-term and short-term plans. The transaction quantity in the market is defined as the smaller of effective demand and supply. Using the traditional global fitting method, three models are evaluated: one model that assumes no …

A Non-Decision-Reaching Decision-Making Process, Wei Wei Lou

Dissertations and Theses

Decision-making processes are among the most important activities within human organizations. This dissertation is a case study of decision-making in the review of high school graduation standards in an urban school district. The review process lasted three years and was terminated before any decision was reached concerning graduation standards. The purpose of this study is to answer three questions: Why would a decision-making process be terminated before any results are achieved? Under what circumstances do decision makers choose to let the process die? What do such decision making processes reveal about the organization? This case study employs the rational choice …

Spiritual Health: Association For The Advancement Of Health Education Instructors' Attitudes, Practices And Training, Susanne Meyer Christopher

Dissertations and Theses

Health education uses a holistic, multi-dimensional perspective (Hoyman, 1961; Donatelle, 1991; Hales, 1992). In recent years an emergent issue in health education is concern for disproportionate representation among the human dimensions--emotional, social, physical, intellectual, spiritual. Discussion occurs over the apparent underrepresentation of spiritual health in health education materials (Chandler & Kolander, 1990). While the professional literature contains articles discussing the under-representation of spiritual health (Jose & Taylor, 1986; Bensley, 1991), no empirical studies are available to assess the current status of spiritual health in health education materials or the spiritual health attitudes of health educators. This study provides empirical data …

A Case Study Of The Development Of Oregon's 1985 Public Policy In Youth Substance Abuse, Sonja Carol Grove

Dissertations and Theses

Youth substance abuse in Oregon reached epidemic proportions in the early 1980s. A response to this social issue from the Governor's Office, the state legislature, and the Office of Alcohol and Drug Programs during 1983-1985 is the foundation of this case study. Oregon, a small state of three million, was faced with a growing problem of youth and adult substance abuse. Legislative leaders, agency staff, and Governor Atiyeh recognized an opportunity to create public policy to solve problems of substance abuse including crime. The focus on substance abuse included streamlining several budgets with substance abuse monies in various state agencies. …

Tunnel One Generalized Satellite Knots, John Ralph Neil

Dissertations and Theses

In 1984, T. Kobayashi gave a classification of the genus two 3-manifolds with a nontrivial torus decomposition. The intent of this study is to extend this classification to the genus two, torally bounded 3-manifolds with a separating non-trivial torus decomposition. These 3-manifolds are also known as the tunnel-1 generalized satellite knot exteriors. The main result of the study is a full decomposition of the exterior of a tunnel-1 satellite knot in an arbitrary 3-manifold. Several corollaries are drawn from this classification. First, Schubert's 1953 results regarding the existence and uniqueness of a core component for satellite knots in the 3-sphere …

A Study Of Two Attempts By President Plutarco ElíAs Calles To Establish A National Church In Mexico, Roger David Gouran

Dissertations and Theses

In the one-hundred years between 1810 and 1926 there were many civil wars in Mexico. The last of these wars. La Cristiada, was not fought, as were the previous civil wars, by groups seeking political control of Mexico. Rather, the genesis of this war was a question of who would control the Church in Mexico. The war began when President Plutarco Elias Calles attempted to enforce rigorously certain articles of the Constitution of 1917 as well as two laws which he promulgated. If Calles had succeeded, he would, in fact, have created a church in Mexico controlled by the federal …

On Modeling Of A Mobile Multipath Fading Channel, Heng Xiao

Dissertations and Theses

Multipath fading is one of the major practical concerns in wireless communications. A multipath transmission takes place when a transmitted signal arrives at a receiver by two or more paths of different delay. Such multiple paths may be due to atmospheric reflection or refraction, or reflections from buildings or other objects. A multipath fading channel is usually modeled as a time-variant tapped delay system. RAKE receiver can be used to detect the signal from the multipath fading channel. However, the number of delay taps, the time delay of each path, and the tap weight for each delay path need to …

The Anabaptist Contributions To The Idea Of Religious Liberty, Barbara Monette

Dissertations and Theses

The relationship between ideas and history is important in order to understand the past and the present. The idea of religious liberty and the realization of that ideal in sixteenth-century Europe by the Anabaptists in Switzerland and South Germany in the 1520s was considered to be revolutionary in a society characterized by the union of church and state. The main impetus of the idea of religious liberty for the Anabaptists was the application of the New Testament standard of the Christian church, which was an independent congregation of believers marked only by adult baptism.

The purpose of the present study …

Methodology For Accurate Speedup Prediction, Aruna Chittor

Dissertations and Theses

The effective use of computational resources requires a good understanding of parallel architectures and algorithms. The effect of the parallel architecture and also the parallel application on the performance of the parallel systems becomes more complex with increasing numbers of processors. We will address this issue in this thesis, and develop a methodology to predict the overall execution time of a parallel application as a function of the system and problem size by combining simple analysis with a few experimental results. We show that runtimes and speedup can be predicted more accurately by analyzing the functional forms of the sequential …

Indicators Of Nutrient Limited Plankton Growth In Lakes Near Mount Saint Helens, Washington, Kurt Davis Carpenter

Dissertations and Theses

Several lakes located in the blast zone of the 1980 eruption of Mount St. Helens were studied to determine if the plankton in the lakes were limited in their growth by nitrogen or phosphorus availability. Long term nutrient enrichment experiments were performed on lake water from five lakes and measures of chlorophyll-a, carbon fixation, and nutrient uptake were used to evaluate the extent of limitation. Nutrient concentrations, ratios, and uptake from 14 lakes provided additional evidence for limitation by nitrogen and/or phosphorus. The physical, chemical, and biological characteristics of the lakes were also examined to monitor the return of these …

Causal Attributions For Teen Problem Drinking, Barbara J. Seatter

Dissertations and Theses

Teen problem-drinking is a pervasive problem in our society. Teens with drinking problems utilize treatment centers and then return to school attempting to stay sober. However, many return to affiliate with problem drinkers instead of with non-drinkers, and risk for relapse is high. One explanation may be that teens without drinking problems do not accept teen problem drinkers into their peer group due to negative reactions toward problem drinkers. One way to examine their attitudes is to examine differences between teen problem drinkers and non-drinkers regarding causal attributions. Attribution theory proposes that various attributions will elicit different emotional reactions and …

Predicting Solute Transport In Natural Streams - A Stochastic Approach, Xueqing Zhou

Dissertations and Theses

The existing theories for predicting longitudinal dispersion in straight open channels have long been recognized as inadequate when applied to natural rivers. These theories tend to grossly underestimate dispersion in real streams since an important mixing mechanism due to nonuniform river cross-section variations is not explicitly taken into account. Recognizing the important role of stream irregularities on solute transport and the analytical difficulties of classical deterministic analysis, we develop a stochastic approach for analyzing solute transport in natural streams. Variations in river width and bed elevation are conveniently represented as one-dimensional random fields, characterized by their autocorrelation functions. Advection and …

Erp Analysis Using Matched Filtering And Wavelet Transform, Xueming Lin

Dissertations and Theses

Event related potentials (ERP's) carry very important information that relates to the performance of the brain functions of the human being. Further studies have identified that one component, in particular, P₃₀₀, is affected by the memory process. Matched filter is used to improved the SNR of signal ERP's. We use the output of the matched filter to distinguish the difference of the waveforms between normal subjects and memory-impaired subjects. In our study, we found that the peak values of the matched filtering output were different between normal subjects and memoryimpaired subjects. Also, as an application, wavelet transform is …

Investigations On Glycolipid Production By Pseudomonas Putida Grown On Toluene In Batch And Continuous Culture Conditions, Keith Foorest Dockery

Dissertations and Theses

Utilization of toluene by Pseudomonas putida as its sole carbon and energy source affects morphology, outer membrane protein composition, and glycolipid production. Two strains of P. putida were found to utilize toluene and to coexist in continuous and batch culture. The two strains were designated translucent and opaque, based upon their readily identifiable coloration when grown on Luria agar. The translucent strain was the dominant strain in continuous culture conditions. The outer membrane proteins of P. putida were separated by sodium dodecyl sulphate polyacrylamide gel electrophoresis. When toluene is the carbon and energy source, the trend in protein composition was …

An Improved English Article System For Japanese Speakers, Dorothy Jean Frew

Dissertations and Theses

One aspect of the English language which has been overlooked by English-as-a-Second-Language educators is the article system, a, the, and 0. For students from articleless first languages such as Japanese, learning this complex system is a formidable challenge. Performance studies show an error rate among advanced Japanese students of approximately thirty percent. There may be several reasons for this high rate: 1) the differences between Japanese and English, 2) the unusually high degree of complexity/difficulty of the article system itself compared to other English morpheme systems and 3) inadequate treatments of the subject as revealed in this …

The Origins And Development Of The Defense Forces Of Northern And Southern Rhodesia From 1890 To 1945, Eugene Peter Jarrett Pomeroy

Dissertations and Theses

This thesis examines Northern and Southern Rhodesia's history through the formation and development of their police and military units from the time Rhodesia was created in 1890 until the end of the Second World War. Southern Rhodesia, founded after a series of short and bloody frontier wars, was a self-governing British colony under a white minority and centered its peace-time security efforts around keeping an eye on potential uprisings from the African majority. White Northern Rhodesians viewed the African majority with similar suspicion although they were never able to exclude Africans from territorial defense. Northern Rhodesia was governed from London …

Strategies In Theodore Dreiser's Trilogy Of Desire To Resolve The Division Between The Material And The Spiritual, Claas Riese

Dissertations and Theses

A study of strategies and attempts in Theodore Dreiser's novels The Financier, The Titan and The Stoic to resolve the conflict between the material and the spiritual. The purpose of this thesis is to demonstrate that conflicts in Dreiser criticism reflect unresolved conflicts between these issues in his "Trilogy". Having outlined and shown the division in the literary criticism of the "Trilogy", in the first chapter of this thesis, I will discuss the three main themes, finance, art and women, which can be seen as strategies to bridge the division between the material and the spiritual. I will attempt to …

Changes In Proteins Associated With Nitrogen Fixation And Iron Nutrition In The Marine Cyanobacterium Trichodesmium, Karen Marie Elardo

Dissertations and Theses

This investigation tested the hypothesis that iron, as a micronutrient, will affect proteins in Trichodesmium and therefore affect nitrogen fixation. Changes in proteins that are a result of iron enrichment were compared to naturally occurring diel changes. Alterations in the iron protein of nitrogenase were compared to nitrogen fixation rates using the acetylene reduction technique. The observed changes in proteins were compared in Trichodesmium colonies from the Caribbean Sea and the Sargasso Sea.

Trichodesmium colonies were monitored for protein and iron content over a diel period on two cruises. The changes in protein and iron content in Trichodesmium colonies were …

Establishing Us Military Government: Law And Order In Southern Bavaria 1945, Stephen Frederick Anderson

Dissertations and Theses

In May 1945, United States Military Government (MG) detachments arrived in assigned areas of Bavaria to launch the occupation. By the summer of 1945, the US occupiers became the ironical combination of stern victor and watchful master. Absolute control gave way to the "direction" of German authority. For this process to succeed, MG officials had to establish a stable, clearly defined and fundamentally strict environment in which German officials would begin to exercise token control. The early occupation was a highly unstable stage of chaos, fear and confusing objectives. MG detachments and the reconstituted German authorities performed complex tasks with …

Language Learning Strategies Of Russian-Speaking Adult Esl Learners, Minerva E. Renee Kalenandi

Dissertations and Theses

In the ESL classroom, there are often cultural differences between learners and teachers. Sometimes these differences can lead to misunderstandings or even conflict. One area where differences between cultures can be seen is language learning strategies and styles. This study explores the possibility that awareness of differences, explicit teaching, and negotiation may help to resolve differences.

This study looks at differences between Russian-speaking adult ESL learners and American ESL teachers, with respect to strategy use and preferences. Three aspects are investigated. The first is to see whether there are statistically significant differences between these groups of learners and teachers. The …

A Comparison Of Neutrophil Migration In The Mouse In Response To Infection With Three Species Of Trichinella, Jon Darin Prulhiere

Dissertations and Theses

The Genus Trichinella is currently thought to consist of 8 separate species. Several methods have been used to help differentiate these. In this study the ability of three of these species, T. spiralis, T. pseudospiralis, and T. sp. 3 to independently infect MRL++ mice was compared at 5, 7, 11, 18 and 20 days post infection (dpi) with the hope of discovering new distinguishing characteristics. Of interest was the development of inflammation through the accumulation of neutrophils associated with larvae of Trichinella in mouse skeletal muscle. This was evaluated with routine histological stains, endogenous peroxidase staining and immunohistochemical …

Women Who Select Naturopathic Health Care During The Menopausal Transition: A Study In Grounded Theory, Dorothy S. Tibbetts

Dissertations and Theses

A grounded theory method was used to investigate the experiences of women who use naturopathic medicine, a system of alternative therapy, for health care during the menopausal transition. Transcripts of 16 in-depth interviews with women who received naturopathic health care during the menopausal transition were analyzed with respect to three research questions: (a) Why do women seek naturopathic health care during the menopausal transition? (b) Do women who use naturopathic treatment for menopausal health care share similar experiences of menopause? and ( c) Are women satisfied with the naturopathic treatment they receive for menopausal health care? Conditions leading to informants' …

Two Dimensional Finite Element Modeling Of Swift Delta Soil Nail Wall By "Abaqus", Richard James Barrows

Dissertations and Theses

Soil nail walls are a form of mechanical earth stabilization for cut situations. They consist of the introduction of passive inclusions (nails) into soil cut lifts. These nailed lifts are then tied together with a structural facing (usually shotcrete) . The wall lifts are constructed incrementally from the top of cut down. Soil nail walls are being recognized as having potential for large cost savings over other alternatives. The increasing need to provide high capacity roadways in restricted rights of way under structures such as bridges will require increasing use of techniques such as combined soil nail and piling walls. …
