A Theoretical And Experimental Examination Of Sodium Chloride Hydration, Debra Conway Modra

Dissertations and Theses

A Hitachi Hu 125C transmission electron microscope in which the standard specimen holder was replaced by an environmental cell was used to observe the hydration of sodium chloride crystals. To observe Kelvin curvature and solubility effects sodium chloride crystals which were 0.1u or smaller were of special interest. An electrohome video system attached to the electron microscope was used to record the sodium chloride hydration for subsequent particle measurement and viewing.

A theoretical model was also developed. Thermodynamic properties such as the Kelvin curvature and solubility effects were considered as well as the kinetic expressions for salt dissolution/recrystalization and water …

Intelligence Testing Of American Indian Children: Sidesteps In Quest Of Ethical Practice, Richard H. Dana

Regional Research Institute for Human Services

Previous literature reviews are updated. Recent findings impugn the WISC-R internal consistency and document item bias for American Indian children. A pattern of Spatial > Sequential > Conceptual > Acquired Knowledge holds across ages, tribes, and heterogeneous referral sources, except for acculturated children. Kaufman's three factors are replaced by Verbal and Performance factors for Papago and Navajo children. A culturally-learned basis for intellectual functioning among traditional children supports alternative assessment functions for traditional reservation lifestyle and for acculturation and entree into mainstream society. Performance measures, SOMPA, Piagetian and Luria-derived tasks may ultimately provide less biased intelligence estimates. Recent legislation outlines ethical practice although …

Spies In America : German Espionage In The United States, 1935-1945, Joan Irene Miller

Dissertations and Theses

This thesis addresses the topic of German espionage in the United States between 1935 and 1945. It examines what the expectations were for Germany's spies in America, their activities, and the success or failure of their operations.

Forecasting Interest Rates Using Pattern Recognition Techniques, John S. Pearson

Dissertations and Theses

Much depends on the future course of interest rates. The decisions of families to make major purchases, the willingness of businesses to expand and invest, the rise and fall of the economy and stock market, the ability of lesser developed countries to repay their debts, the tenure of presidents and prime ministers--all of these may turn on whether interest rates increase or decrease in the months ahead. Several decision functions developed in the dissertation permit the direction of change of interest rates on long-term U. S. government bonds to be forecast correctly about 60% of the time. When the different …

Urban Housing Policy Evaluation In The Kingdom Of Saudi Arabia, Tarek Ali Fadaak

Dissertations and Theses

The rise in wealth for the Kingdom of Saudi Arabia led to an increase in demand for more and better housing. In response to this rising demand, and as part of an overall development policy, a housing 60a1 and several housing objectives were identified. To attain the goal and objectives, a formal housing policy was designed and authorized. It involved direct and indirect assistance to the private sector, a subsidized financing program for new housing construction, a serviced land program for the low income, and public housing. This thesis is an evaluation of the urban housing policy in the Kingdom …

The Contribution Of Social Support To The Successful Functioning Of Men With Epilepsy, Diane L. Pancoast

Dissertations and Theses

One hundred men with epilepsy were interviewed about the history of their illness, employment history and personal support network. Included as sources of support were: household members, close friends and relatives, more distant relationships and general forms of social participation such as church membership. Four potentially supportive aspects of these relationships were assessed: structural features of the pattern of relationships; characteristics of the individual ties; exchanges of helping resources and subjective assessments of the supportiveness of ties. The social support networks of the men who were satisfied with their lives were large, diverse, active and generally helpful. Church membership was …

An Investigation Of The Relationship Between Biographical Characteristics And Job Satisfaction Among Middle School Teachers In Four Suburban School Districts, Susan Scott-Miller

Dissertations and Theses

Quality Circles (QC) took root in Japan during the 1960s and was introduced into the U.S. in 1974. Today, many people believe QCs can increase teacher and school effectiveness. Beyond the realm of opinion, however, little research supports this belief. This study had three purposes. The first was to review QCs' literature. The second was to identify QC structures and problem solving procedures. The third was to test QCs in an educational setting and to analyze their effects on the attitudes of teachers. Methodology. QC groups and comparison groups were established at four school sites. Two measurement instruments, the Work …

Effective Acquisition Of Basic Skills: An Elementary Schools Program, Linda L. Terhark

To obtain data regarding the three areas of multicultural education policy status, implementation and impact, a survey was sent to all fifty chief state school officers (CSSOs). The survey inquired about the current status of multicultural education policy mandates and administrative processes used in policy implementation. Policy impact was assessed through CSSO's responses to ten …

Enhancing Impact Assessment With Extrapolative Fiction, Ruth-Ellen Miller

Dissertations and Theses

This dissertation proposes the use of fiction as models to enhance the process of impact assessment (IA) and to improve the quality of IA reports. It demonstrates that works of extrapolative fiction (EF), a subset of science fiction, raise issues and clarify concerns not currently included in the IA process, suggesting the potential for improving the relevance of IA results for decisionmakers. The dissertation also demonstrates that EF stories can enhance the presentation of IA results, making those results more readable. Through literature review and content analysis, the current IA process is shown to lead to results lacking in specific …

Computer Modeling Of Photochemical Ozone Formation: A Simplified Approach, Ebrahim Moshiri

Dissertations and Theses

Photochemically produced ozone represents a worldwide enviromental hazard. Controlling ozone formation in polluted air requires control of hydrocarbon and nitrogen oxides precursors. The degree of control can be established with the chemical model of the reacting species. A hydrocarbon-specific photochemical ozone model is developed, based upon a minimum set of chemical equations. This model eliminates the need for the traditional "brute force" approach to integrate systems of tens or even hundreds of simultaneous differential equations. We have sought to develop the full kinetic potential for simplification which this chemical system may have. Key features of the model are reaction of …

The Relation Of Economic Diversity To Levels, Growth Rates, And Stability Of Unemployment And Income, Mohsen Attaran

Dissertations and Theses

The purpose of this study is to investigate some widely-held assumptions regarding the value of diversification as an economic strategy. It has ofien been suggested that economic diversity enhances economic performance, either by promoting higher levels of economic well-being or by improving the ability of regions to cushion the adverse effects of economic cycles. This is the conventional wisdom, but it has not been adequately tested, although some attempts have been made to relate measures of diversity to other economic indicators (e.g., Rodgers, MacLaughlin, Conkling). The current study explores this particular issue, and the results obtained should be of interest …

Satisfaction And Quality : Patient Perspectives In Medical Care, Marguerite L. Foeller

Dissertations and Theses

Patient dissatisfaction with the physician/patient relationship and medical care is well documented in both the lay press and the medical literature. This problem appears to stem from communication between physician and patient and is drawing increased attention from the communication discipline. Research conducted in interpersonal communication satisfaction theory provides a basis for this study of patient satisfaction with physician/patient communication and its relationship to the perceived quality of medical care.

This paper reports two sets of interviews with a total of 108 respondents on the topic of physician/patient communication which resulted in the identification of nine salient issues which appeared …

The Psychological Intervention Of Group Therapy For Women Coping With Genital Herpes, Susan D. Ferguson

Dissertations and Theses

Three groups of women who had been diagnosed as having genital herpes completed a series of psychological assessments over the course of the four-month research period. One group received two-hour weekly group psychotherapy sessions for eight consecutive weeks as a mode of treatment intervention. Two control groups were used for efficacy of treatment comparison. One control group consisted of regular members of a local self-help chapter for herpes victims. The second control group was formed from those volunteers willing to participate, but who did not choose, or desire, any form of treatment, Outcome measures reflected a greater improvement in psychological …

Normative Data For The Tennessee Test Of Rhythm And Intonation Patterns (T-Trip), Ray Drommond

Dissertations and Theses

Prosody is the flow of speech created by controlling elements such as pitch, rate, loudness, and stress (Tiffany and Carrell, 1977). Prosody is vital to intelligibility of speech and also communicates meaning. Despite the importance of prosody, however, few tests for the adequacy of prosodic ability in young children have been published (Koike and Asp, 1981a). To remedy this paucity of tools, Koike and Asp published the Tennessee Test of Rhythm and Intonation Patterns (T-TRIP). The clinical usefulness of the T-TRIP has been limited by a lack of normative data against which to compare individual children's performance.

The purpose of …

Dissertations and Theses

The purpose of this study was to collect normative data on the auditory memory performance of three- and four-year old children as measured by the Auditory Memory Test Package (AMTP). Specifically, this investigation sought to answer one question: is the AMTP sensitive to age differences when administered to young children ages 3.0-4.11?

A Validation Study Of The Screening Test For Developmental Apraxia Of Speech, Deborah L. Thorsen

Dissertations and Theses

The term "developmental apraxia of speech" (DAS) has been a confusing one since Morley, Court and Miller (1954) first applied it to articulatory patterns of a specific group of children. Until recently, the differentiation of diagnostic features of DAS in children as compared to other articulatory disorders has been difficult. One evaluation tool, developed by Blakeley (1980), to assist in differential diagnosis of DAS is the Screening Test for Developmental Apraxia of Speech (STDAS). This study examined the validity of this tool by comparing its results with the evaluations by three Speech-Language Pathologists knowledgeable in the area of developmental and/or …

State Space Approach To Flood Stage Estimation, Gregory Allen Jones

Dissertations and Theses

A flood routing and stage prediction model is developed using the techniques of State Space and Kalman filtering. The governing equation is the physically based hydrologic method of flood routing with the output being an optimal estimate of stage given known inputs of streamflow. These equations are developed in state space and the Kalman filter is employed to estimate the flow and river stage.

The model is applied to the Toutle and Cowlitz Rivers in the State of Washington, where the stage is affected by a shifting bed elevation. With the deterministic inputs at Mayfield Dam on the Cowlitz and …

Survey Of Language Acquisition Techniques Provided By Parents Of Talented And Gifted Children, Sharon Engen

Dissertations and Theses

Most of the studies on language acquisition techniques provided by parents have been addressed to the training of parents for prevention of language disabilities and disorders (Latzke, 1975). Few investigations have involved language acquisition of the superior functioning child (Patterson, 1981). Hence, the purpose of this study was to survey language acquisition techniques provided by parents of talented and gifted children (TAG) who were enrolled in the Beaverton School District Number 48 TAG program. The first question dealt with what materials and/or equipment did the parents use in aiding their child's language development. The second question dealt with which particular …

Strong-Minded Woman Figures In A Time Of Crisis : Maria Stuart, Penthesilea, Sappho, Inger M. Olsen

Dissertations and Theses

The strong-minded woman as a character capable of genuine self-determination has not received nearly as much literary attention and study as the less psychologically and socially aware sublime woman, the innocent woman, and the femme fatale. Consequently, the strong-minded woman is only an occasional literary phenomenon and is absent entirely during some literary periods.

Thus the purpose of this thesis is to establish that the strong-minded woman exists as a literary figure, that she is a fully developed character capable of forming meaningful and even traditional relationships when allowed by circumstances. She is capable of relying on her own abilities …

You Don't Have To Have A High School Education To Work Here : An Ethnography Of A Chainstore, Caroline Yvonne Princehouse

Dissertations and Theses

This ethnography is a study of the cultural scene at one store of a chain of twenty-eight retail "discount department stores"--the Bi Mart Company, a subsidiary of the Pay 'n Save Corporation. It is an exercise of an ethnographic method developed by James Spradley that is used to uncover and describe the cultural grammar of acquired knowledge which Bi Mart employees use to define and interpret their situation and to generate and understand their work. The method is based on the assumption that culture is best learned and best described (as much as possible) from the "native" point of view.

Dance Therapy And Self-Concept Change In Psychiatric Patients, Cheryl Jeanne Hall

Dissertations and Theses

This study investigated the effects of various forms of therapy (individual, occupational, and dance) on self-concept. Subjects were 29 psychiatric patients at Providence Medical Center who volunteered to participate in this study. The Tennessee Self-Concept Scale (TSCS) was used to measure self-concept both at time of admission and prior to discharge. The data were analyzed in a step-wise multiple regression to determine which of the various forms of therapy are the best predictors of self-concept at second TSCS application. The results of the step-wise multiple regression did not support the hypothesis that exposure to dance therapy would be a significant …

Femininity And Self-Esteem In Professional Women, Shirley Ellen Harper

Dissertations and Theses

Research in sex-roles has found masculinity and androgyny to be correlated with self-esteem while femininity has a low or negative correlation with self-esteem. Much of the research in this area is based in studies of androgyny. Androgyny is the ability to respond in a feminine or masculine manner, depending on the situation rather than being limited to only feminine or masculine behavior because of sex-role stereotypes. In the research on self-esteem some studies have reported androgynous individuals measure high in self-esteem. Other studies have found that masculine characteristics contribute more to the self-esteem than androgynous characteristics. These results, taken together, …

The Effects Of A Combined Weight Training And Running Program On Body Composition In College Males, Robert L. Hesslink Jr.

Dissertations and Theses

The present study attempted to investigate whether a combined weight and endurance training program can elicit more favorable changes in body composition than either method of training alone. Body composition parameters (absolute fat and fat-free weight) were evaluated using circumference measurements, skinfolds and hydrostatic weighing. Cardiorespiratory fitness was evaluated via a modified Harvard step-test. All tests were administered before and after 10 weeks of training. Exercises were performed 3 days/week for 40 minutes/day. Male volunteers (n=21) were randomly assigned to one of three treatment groups (weight training only, endurance running only, combined weight training and endurance running).
