The Status In 1980 Of The Toulmin Model Of Argument In The Area Of Speech Communication, Jeffrey Robert Sweeney

Dissertations and Theses

In 1958 Stephen E. Toulmin wrote of inadequacies of formal logic and proposed a new field-dependent approach to the analysis of arguments. Despite a generally negative response to his proposal from formal logicians, Toulmin's model for the laying out of arguments for analysis was subsequently appropriated by several speech communication textbook writers. In some textbooks, the Toulmin model has become successor to the syllogism as the paradigm of logical argument. Yet, perhaps due to their seemingly uncritical acceptance of Toulmin's approach there appears to be serious disagreement and confusion among speech communication professionals about the nature and applications of the …

Social Resources Of The Elderly As Correlates Of Life Satisfaction, Silvana Rigo Hale

Dissertations and Theses

This project has addressed the need for a new and effective theoretical framework in the field of social gerontology by proposing and applying exchange theory as a valid approach to the study of aging. This study specifically analyzed the relationships between life satisfaction and social resources, social contexts and change in order to measure and clarify the significance of the individual factors.

Aboriginal Clay Figurines From The Upper Rogue Valley In Southwestern Oregon, Lyman Patrick Deich

Dissertations and Theses

A study of 80 clay figurines from aboriginal sites in the upper Rogue River Valley in southwestern Oregon fails to reveal any connection with other figurines found in the Pacific Northwest and northern California. A preference for animal rather than human representations is demonstrated. The temporal distribution of the figurines is not known, but spatial distribution appears roughly coextensive with territories occupied by the upland Takelma at the time of Euro-American contact during the second quarter of the nineteenth century.

Adaptation To Dominant Society : A Self Study Of A Woman Of Mixed Race, Black/Indian, Helen Marie Camel

Dissertations and Theses

This research effort is based on the life and development process which the author has experienced and is currently experiencing. This effort for all intents and purposes, is an individual self-study. "Critical Incidents" have been utilized to develop a sense of understanding for the reader. In reading this paper, one can see that at times negative social and cultural situations would cause the author an unusually high level of inner stress, which was not always apparent to the outside world.

Salem Teen Mother Program: A Follow-Up Study, Frances L. Barton

Dissertations and Theses

Society has, historically, reacted to teenage pregnancies with a mixture of embarrassment, apathy and neglect. It wasn't until the 1960's that an attempt was made to design and implement programs to meet the needs of pregnant adolescents. An example of such a program is the Salem Teen Mother Program. This program was begun in 1966 and is affiliated with the local YWCA. If offers a comprehensive program to approximately 150 students each year. The services it offers include day care, social services and counseling, education, health services, parenting skills and employment counseling.

The following chapters include a literature review which …

A Study Of The Crisis Nature Of The Preparenthood Period And Implications For Preventative Social Work Practice, Julie Jean Colton

Dissertations and Theses

This study addresses the preparenthood period of family life, that period from conception to six weeks after the infant is born. This period was of great interest because in nine years of social work practice I have recognized that families resist change after their particular family system process, even destructive process, is established. I also believe that the order, or disorder, of society depends upon the order of the institution of the family. Other institutions of society depend upon the family for their existence.

Geology Of The Columbia River Basalt In Silver Falls State Park, Oregon, Elizabeth Storm Norman

University Honors Theses

Silver Falls State Park is near the southern extent of the Columbia River Basalt Group as mapped in western Oregon. The flows in the park were identified as belonging to subdivisions of the Columbia River Basalt Group on the basis of physical characteristics and trace element geochemistry. The sequence of flows present is as follows: 3-4 flows of the Low-Mg chemical type of the Grande Ronde Basalt, 2 flows of the High-Mg chemical type of the Grande Ronde Basalt, 3 flows of the Frenchman Springs Member of the Wanapum Basalt, and one flow of anomolous geochemistry. The flows dip west …

A Study Of The Photolysis Of O-Methyl Podocarpinitrile Oxide, Dianne Marie Hunter

Dissertations and Theses

The photolytic reaction of 0-methyl podocarpinitrile oxide to yield the δ-lactam (shown below) was studied under various conditions such as: solvent (hexane, methanol), mercury lamp wattage (lOOW, 450W), filter (Pyrex, Corex, Vycor), and additives (dichloromethane, hexafluorobenzene). The reactions were analyzed with IR, NMR and HPLC. Preparative medium pressure liquid chromatography and TLC were used in the δ-lactam isolation. The conditions resulting in the optimum yield of δ-lactam were determined. The photolytic stability of the δ-lactam under the conditions in which it was formed indicated that it was relatively stable only in hexane.

Alienation Under The Rainbow: A Survey Of Oregon Graduate Students, Robert Michael Travis

Dissertations and Theses

Nisbet's theory of alienation entails three propositions: 1) alienation is a unidimensional phenomenon; 2) alienation is a generalized phenomenon; and 3) power relations foster loss of community which engenders alienation. All three propositions were tested on a population of graduate students at a university in the Pacific Northwest.

The Parcelization Of The Open Range, A Conflict In Land Use : Grazing Rights Versus Residential And Recreation Land Sales In Klickitat County, Washington, Dennis A. Olson

Dissertations and Theses

The threefold question researched herein is: (1) What are the extent and potential economic consequences of land parcelization in Klickitat County?, (2)What are the political and social costs of parcelization?, and (3) What measures today are, or could be, used to ameliorate the land use conflict? These are answered by studying the various aspects of the problem, including the historic land use change, legal mechanisms which regulate livestock grazing and land parcelization; taxation; the economic-effect upon livestock production; crime and social conflict; costs to county services; and environmental impacts. The geography of the change itself is depicted on several maps.

Evaluative Styles Of Clinicians In Private Practice, Daniel R. Brophy

Dissertations and Theses

A belief shared by all members of the research team was that evaluation is a tool that can be used to improve the effectiveness of clinical practice. Prompted by this interest, a research project was designed to gather descriptive data about evaluation in the private sector. The research question reads:

To what extent and in what way are licensed clinical psychologists and clinical MSW's in the private sector involved in evaluating their practice?

a. Are these clinicians using formative and/or summative evaluation?

b. What techniques and/or mental processes do they use?

Multiple Impact Therapy: Evaluation And Design For Future Study, Jacqueline H. Abikoff

Dissertations and Theses

The theoretical underpinnings of Washington County Children's Services Division (CSD) Immediate Conflict-Resolution Family Treatment Program include the systems theory of family therapy with a focus on communication and roles. One of the many approaches to helping families in crisis, it incorporates theories regarding assessment of and intervention in families in crisis. Finally, while it draws upon several different approaches to family therapy, the Washington County program is most closely related to Multiple Impact Therapy (MIT). Thus, a review of relevant literature must address portions of the above enumerated theories that illuminate the thinking behind the Immediate Conflict-Resolution Family Treatment Program. …

A Generalist Approach To Social Work Practice: Model And Synthesis, Chuck H. Johnson, Paul S. Knight, Michael W. Krumper, John H. Rademaker

Dissertations and Theses

The purpose of this research practicum is twofold. First, to present a synthesis of current generalist literature and to formulate a practice model which is both comprehensive and representative of current generalist practice in direct services. To our knowledge there is no single reference or source which in and of itself accomplishes this purpose. Therefore, such a model would make an important contribution to the field. Second, to develop a questionnaire which could be used to conduct a descriptive survey of generalist social work practice in Oregon. It would determine the extent to which practitioners in Oregon are practicing as …

Effect Of Phenoxy Acids And Their Derivatives On The Ionic Permeability Of Bilayer Lipid Membranes, Malkanthi Paulis Illangasekare

Dissertations and Theses

It has been found that the herbicide 2,4-D has the ability to increase the rate of transport of positive ions of several kinds and inhibit the transport of negatively charged tetraphenylborate ions in lipid bilayer membranes. Only the neutral molecules of 2,4-D are transport active. The ionized 2,4-D molecules do not modify the transport of ions, and do not by themselves permeate through lipid membranes. The results suggest that the enhancement of transport of positively charged ions is dominated by the increase of the ion translocation rate constant. It has been shown that membrane transport of negatively charged tetraphenylborate ions …

A Construct Validity Study For The Women Workers Scale Questionnaire, Gwen Simpson

Dissertations and Theses

This study attempted to obtain evidence on the construct validity of the Women Workers Scale (WWS), an attitude scale developed to measure male supervisors' attitudes toward women workers. As women enter the work world in increasing numbers, they are usually supervised by men. However, few studies have examined the attitudes of male supervisors toward women workers. At least one author (Bass, 1972) reported that there were significant differences among male managers in their attitudes toward women. Specifically, those male managers who had not worked with women held more favorable attitudes than male managers who had worked with women.

Dance And Self Concept Change In Women, Robin Dale Anderson

Dissertations and Theses

Numerous authors in the field of dance therapy have proposed that dance movement employed as a psychotherapeutic tool yields positive gains in mental health for participants. Self concept is frequently cited as the mechanism affecting these gains. In order to explore the relationship of dance movement alone to self concept fifteen college women were tested with the Tennessee Self Concept Scale before and after participation in a course of dance with those of nineteen women enrolled in lower division psychology courses. An analysis of covariance showed no significant changes in self concept scores in either group. It was concluded that …

A Critique Of Bandler And Grinder's Method Of Mapping Representational Systems, Leslie E. Goldmann

Dissertations and Theses

People perceive the world in their own terms: our use of language reflects our perceptions. The way in which we perceive the world and the words we use to reflect that perception Grinder and Bandler (1976) call a "representational system." The authors isolate three types of representational systems, visual, kinesthetic, and auditory, and they present a technique for mapping these systems. These authors state that a sensory preference profile can be mapped accurately and reliably via an individual's use of language. For example, words such as "clear," "see" and expressions of the kind "I get a picture" would connote a …

Changes In Populations Of Soil Acari During The First Year After Clearcutting, Sue Ellen Orlaske

Dissertations and Theses

Soil samples taken from a clearcut and adjacent uncut site of a Douglas Fir and Western Hemlock old growth forest in the Cascade Range of southern Washington showed greatly reduced adult and juvenile population densities of macro-phytophagous, microphytophagous, and predatory soil acari in the clearcut. These effects appeared to be due to high lethal summer litter temperatures and reduced pore spaces due to scarification. Also, the number of species of acari in the clearcut was lower than in the control after clearcutting.

Functional Analysis Of Great Basin Projectile Points, Roger Wiggin

Dissertations and Theses

This paper presents a refined methodology for distinguishing the stone points of arrows from the stone points of spear thrower darts in archaeological assemblages from the Great Basin. The methodology was developed from a sample of 111 complete stone points collected during the archaeological reconnaissance and testing of the Malheur National Wildlife Refuge, Harney County, Oregon, 1971-1974. The points were measured for five metric variables and frequency histograms of each variable were generated by computer. The effectiveness of each variable as an index of functional class (i.e., arrow point vs. dart point) was judged on the basis of the apparent …

Central Auditory Processing In Children With A History Of Chronic Middle Ear Problems, Beverly S. Schnabel

Dissertations and Theses

The purpose of this study was to investigate the central auditory processing of children who had sustained chronic middle ear problems during their early language-learning years. A 60% compressed recording of the NU-6 speech discrimination word lists was administered to twenty eight and nine year old normal hearing public school children, reported by their parents to have had repeated middle ear problems during their early years, and to twenty control subjects matched for age from the same public school classes. Differences in compressed and uncompressed word discrimination scores between the experimental and control groups were not found to be statistically …

A Geophysical Definition Of A Klamath Falls Graben Fault, Cynthis Ann Veen

Dissertations and Theses

Four geophysical methods, along with well logs and outcrop data, were used in determining the location of a fault situated on the campus of Oregon Institute of Technology, just north of Klamath Falls, Oregon. The fault displaces rocks of the Yonna Formation, of Pliocene age. Wells located northeast of the fault (on the upthrown side) produce cold water, and wells located southwest of the fault (on the downthrown side) produce hot water. The purpose of this investigation was to define the characteristics of the fault exposed behind a large water tank southeast of the OIT campus.

Copper Toxicity And Extracellular Release In Selenastrum Capricornutum, Michael Edwin Darling

Dissertations and Theses

Copper toxicity was investigated using the green alga, Selenastrum capricornutum. Two major areas were investigated: the forms of copper which are toxic to growth of the alga and factors that can change the concentration of free copper, Cu²⁺(aq), in the growth medium during the logarithmic growth of the organism. This research has shown that S. capricornutum is sensitive to the free Copper ion, Cu²⁺(aq), irrespective of the total copper concentration.
