An Exploration Into The Applicability Of A Psychological Technique For Anthropological Research, Gwendolyn Marie Harris Pierce

Dissertations and Theses

This thesis purports to explore and describe the types of information that would be obtainable to the anthropological researcher if he used the minimally structured small group (MDMS-SG) technique with members of a selected ethnic group. The approach was tried on Japanese Portland State University students and also on Saudi Arab Portland State University students for six sessions each. They were told that a graduate anthropology student wanted to get to know them and learn what they thought she should know about their countries.

The sessions were taped and notes written after each session. This corpus of material was analyzed …

A Regional Approach: City-County Consolidation As A Method Of Local Governmental Reorganization, Anthony Gene White

Dissertations and Theses

City-county consolidated governments are examined to isolate factors important to the success of the consolidation process, and are measured against objective and subjective criteria for the operation of such governments. Data are obtained through survey techniques and statistical analysis of demographic information. Results indicate that such success-oriented consolidation factors inherent in city-county governments do exist and can be interrelated in a mathematical model. Consolidated governments appear to improve their ability to handle urban problems, and officials of consolidated governments are more confident of their ability to handle these problems than are officials of other metropolitan governments reorganized in different manners.

The Environmental Crisis: The Effects Of Ecology Courses On High School Students, Carol C. Fletcher

Dissertations and Theses

It is a basic premise of this thesis that an environmental crisis exists in the world today and has been worsening at least since World War II. The crisis is evident in the population explosion, the deteriorating air and water quality, and the depletion of our natural resources. With the feeling that all persons must become aware, concerned, and involved with the environmental crisis if the trend is to be reversed, this study is concerned with one segment of the population – high school students.

Sociologists, and especially human ecologists, have not been concerned professionally with the environmental crisis, but …

Computer Solution To Inverse Problems Of Elliptic Form: V²U(X,Y) = G(A,U,X,Y), Frederick Alvin Jeter

Dissertations and Theses

One important aspect of our present age of monolithic high speed computers is the computer's capability to solve complex problems hitherto impossible to tackle due to their complexity. This paper explains how to use a. digital computer to solve a specific type of problem; specifically, to find the inverse solution of a in the elliptical equation V²U(x,y) = g(a,U,x,y), with appropriate boundary conditions. This equation is very useful in the electronics field. The knowns are the complete set of boundary values of U(x,y) and a set of observations taken on internal points of U(x,y). Given this information, plus …

Geophysical And Geological Analysis Of A Fault-Like Linearity In The Lower Clackamas River Area, Clackamas County, Oregon, Ronald Jay Schmela

Dissertations and Theses

A fault-like linearity along the lower Clackamas River is evaluated by analysis of physiographic and structural alignments, geological relationships, and by gravity and magnetic data. The study has resulted in the verification of a structural feature extending along the Clackamas River and the eastern front of the Portland Hills.

Physiographic alignments were examined in twelve 15 minute and two 7-1/2 minute quadrangle maps. A significant northeasterly morphologic trend, N. 20⁰ W. and N. 40° W., and other secondary trends, namely, the N-S, E-W, and N. 50-60° E., has developed in the Portland area. The consistent northwest trend is observed throughout …

Ames Trapezoid Illusion: A New Model, Daniel Robert Kelly

Dissertations and Theses

Current explanations for the Ames Trapezoid Illusion are based upon the the absence of cues: the illusion is said to occur at chance. A review of recent literature showed that: (a) the illusion varies in frequency as a function of target shape (b) that the dominant cue to reduce the frequency of the illusion is the variant in retinal height. Based upon the dominance of this cue a new model was presented. Following this model it was hypothesized that observers viewing partial rotation when the target produces the greatest difference in the retinal height of the ends would determine the …

Vocalizations Of The Townsend Chipmunk (Eutamias Townsendii), Greig Michael Warner

Dissertations and Theses

This study describes and analyzes the vocalizations of the Townsend chipmunk (Eutamias townsendii) in Oregon. Tape recordings of calls were collected primarily from Forest Park in Portland (Oregon) during 1970 and 1971, and sonograms of these recordings were produced. Findings were compared with those of Brand (1970) who investigated E. townsendii vocalizations in California. The prominent calls in the vocal repertoire of townsendii are the quist, the quirt, and the chipper. These calls all appear to be warning calls. The quist note is a a chevron-shaped (A) figure representing a sound which begins at a low frequency (1-2 KC), sharply …

Evidence For The Existence Of Two Stable Sites For Cobalt Impurity Atoms In Aluminum, Arun Venkatachar

Dissertations and Theses

Using Fe⁵⁷Mössbauer spectroscopy, two alternative sites occupied by cobalt (10^-4 at. % ) impurity atoms in aluminum have been isolated. The substitutional site A is the stable position after annealing the sample above 840 K, followed by a rapid quench. The impurity atoms in site A are characterized by a single line Mössbauer spectrum (indicative of a cubic environment), a room-temperature f = 0.502 (r. m. s. displ. 0.071 A) and an I. S. (reI. to Fe) = -0.421 mm/sec. For anneals below 770 K the cobalt atoms migrate to site B, which is characterized by a …

Inter-Bureau Power Relations: A Sociological Analysis Of An Ideal Type Organizational Model, Gerald Wayne Potterf

Dissertations and Theses

The research problem of this thesis is an examination of inter-bureau power relations. A modification of Max Weber's classical ideal type bureaucracy is the conceptual model to which sociological analysis is made. An empirical examination of the variance between the conceptual model and data collected in the field is analyzed in order to illustrate inter-bureau power relations. The analysis of the conceptual model is based upon three assertions. They are: (1) inter-bureau power relations are based upon coercion and not cooperation; (2) normative standards that are established by the administrators of the bureaucracy are differentially enforced; and (3) goals that …

Hipólito Irigoyen's Second Administration: A Study In Administrative Collapse, Herman John Hobi

Dissertations and Theses

In 1928 Hipólito lrigoyen was the most popular President that the Argentine people had elected. Two years later his popularity had evaporated and a few hundred military cadets ousted the government. The reasons go beyond this two-year period. Argentina, contrary to popular belief, did not have a democratic tradition. The nation had been ruled by the dominant economic interests up to 1916.

In 1916, Hipólito Irigoyen was elected to his first term. The people expected him to provide them with a decent and honorable life. But in choosing the legal path of elections instead of revolution Irigoyen pre-empted any revolutionary …

The Effectiveness Of Environmental Control In Modifying Problem Behaviors In Mother-Child Interaction, Thomas Whalen Hamilton

Dissertations and Theses

An experiment was designed to test the effectiveness of using standard laboratory environments in producing a broad class of problem behaviors which defined Mother-Child (M-C) interaction difficulties. The effects of four environments, free-time (X), child's game and rules (B), mother's game and rules (C), and clean-up (Z), on the frequency of eight criteria behaviors were tested on 12 M-C pairs over three days of baseline data collection. It was predicted that the frequency of problem behaviors would decrease as a function of environment (X) and increase as a function of environments (B), (C), and (Z). A two factor …

Crystal Structure Determination Of Β-Lactoglobulin From Electron Micrographs, Richard Roeter

Dissertations and Theses

Often electron micrographs exhibit a repeating structure. Sometimes this repeating structure satisfies the definition of a crystal in that it has a three dimensional repeating structure. If the unit cell structure of this repeating structure can be determined it can be used to help categorize different sections of a particular sample. In some cases, the use of optical diffraction analysis of electron micrographs with repeating structure is a method of determining the unit cell structure.

Samples of β-Lactoglobulin were prepared for viewing in the electron microscope using both the crystalline material and carbon replicas of the crystal surface. Because the …

Communicative Abilities: An Analysis Of The Interactions Of Reticent And Non-Reticent Task Groups, Myron W. Lustig

Dissertations and Theses

This study is focused upon an investigation of observable interactive behaviors which might be characteristic of reticence. A reticent individual is defined as one for whom apprehension about participation in oral communication consistently outweighs the projection of gain from the situation.

Previous research in the area of reticence has been focused on an analysis of the reticent student's attitudes toward communication relying primarily upon subject self-reports via journals and the in-depth interview. This in turn has provided possible areas in which observable reticent behaviors might evidence themselves in face-to-face small group communications with other reticents and non-reticents.

An answer to …

Behavioral Changes Due To Overpopulation In Mice, James Robert Hammock

Dissertations and Theses

Previous research has found that if a population were allowed to exceed a comfortable density level, then many catastrophic events occurred such as increased mortality among the young, cannibalism, homosexuality, and lack of maternal functions. The most influential researcher in this area is Calhoun (1962), after whose experimental design a pilot study was fashioned to replicate his results. The results of this pilot study inspired a more detailed research project of which this thesis is an account.

Forty-eight albino mice of the Swiss Webster strain were divided into three groups of sixteen each. Each group consisted of ten females and …

The Effects Of Sociological Theories Of Poverty On Job Training Programs, Michael Richard Deshane

Dissertations and Theses

This thesis is an exploratory study of the effects of two job training programs for the poor in Portland, Oregon. It seeks to illustrate that training programs are designed around certain theoretical conceptions or models of poverty and that these theoretical conceptions ultimately have a strong effect on the enrollees in programs designed on the given theoretical model. Two general theoretical models have been extracted from the literature. The first is the "Culture of Poverty" model and the second may be called the "Closed Opportunity Structure" model.

The culture of poverty model posits that the poor are unable to escape …

Implications Of An Oral-Gestural Training Program In The Acquisition Of Speechreading Skills, Mary Lu Wood

Dissertations and Theses

In order for the hearing handicapped child to derive maximum benefit of language acquisition through maturation, a method of receptive communication is essential at the earliest age possible. It is felt that speechreading is this method. The need for a method of training speechreading cues to prelingual, aurally handicapped children is based on the fact that most visual speechreading methods require the use of language. If speechreading can be regarded as a learning process involving the discrimination of visual cues that maybe disassociated from language expression then training the child to discriminate various facial expressions may actually enhance speech-reading ability. …

Variations In A Color-Line Aftereffect Due To Color Adaptation During Inspection Of The Inducing Stimuli, Joyce Hirsch

Dissertations and Theses

The McCollough Effect is an orientation specific colored aftereffect. That is, following prolonged viewing of a vertical grid on orange ground alternated with a horizontal grid on blue ground, a yellow-orange hue is perceived on an achromatic horizontal grid, and a bluish hue on a vertical grid. McCollough suggested that the colored aftereffect may depend upon color adaptation of a population of neural elements specific to colored edges of a particular orientation. Accordingly vertical edge detectors sensitive to orange adapt during inspection such that when vertical edges are presented on an achromatic ground only those non-adapted color-line detectors respond creating …

Rilke Und ValéRy: Eine Wahlverwandtschaft, Anne Marie Roehr

Dissertations and Theses

The German poet Rainer Maria Rilke was proficient in languages, and his favorite one was French. He had lived in Paris and had many friends in French literary circles. He exchanged letters with some of them before he even met them personally; such was the case with the French poet and writer Paul Valéry. However, before the two poets met, a “meeting of the minds” had taken place in the year 1921.

In the spring of 1921, after a lengthy period of silence, Rilke came across a copy of the Nouvelle Revue Française, a famous literary review, where Valèry had …

The Effects Of Marihuana Extract Distillate On Eating Behavior Of Rats, Terrie Wetle

Dissertations and Theses

Since hunger drive is often used as a motivating factor in animal learning experimentation, it was decided to determine the effects of marihuana extract distillate on the eating behavior of rats. Carlini and Kramer (1965) found marihuana extract injections to have a faciliatory effect upon maze performance. They suggested that facilitation could have resulted from and increase in hunger drive. However, if the dosage level is high, this effect may last for a short time and be followed by a disinterest in food. Scheckel et al. (1968) report that some monkeys, at very high dosage levels of tetrahydrocannabinol starved to …

Effects Of Insulin, Sodium And D-Glucose On Amino Acid Absorption In The Intestine Of Rats, Andre-Gerard Craan

Dissertations and Theses

Amino acid absorption across rat intestine in vitro was inhibited or stimulated by insulin depending on the hormone serosal concentration.

The absence of sodium ions from the incubating solution resulted in a significant decrease of L-alanine absorption. However, L-alanine was enhanced in a sodium-free medium by the addition of insulin on the serosal side of the intestine.

A sizable decrease in L-alanine and L-lysine absorption was produced by introduction of D-glucose (0.2 % and 2 %) in the Krebs-Ringer's incubating buffer. Nevertheless, the presence of D-glucose did not prevent the stimulatory effect of insulin on amino acid absorption.

The Effect Of Labeling Disfluencies As 'Stuttering' And Contingent And Yoked "Wrong" On The Disfluencies Of Normal Speakers, Dennis Ray Staines

Dissertations and Theses

A labeling variable suggested by Wendell Johnson's "diagnosogenic" theory of the onset of stuttering was included in this study of the disfluencies of normal speaking college students in order to explore further the hypothetical relationship between normal disfluency and the onset of stuttering. A total of 60 Ss were randomly assigned to the following groups, each containing 10 Ss: I. Labeling Chastisement plus Contingent "wrong;" II. Labeling Chastisement plus Yoked (non-contingent) "wrong;" III. Labeling Chastisement - No "wrong;" IV. No Labeling Chastisement Contingent "wrong;" V. No Labeling Chastisement - Yoked "wrong;" VI. No Labeling Chastisement - No "wrong" …

Age, Emotional Maturity And The Decision To Marry, Patricia Ann Duclos, David F. Thomas, Joanne Zusman

Dissertations and Theses

The decision to marry and choice of mate are two issues contemplated by most individuals during their lifetime. It is our belief that the manner in which an individual makes these decisions is a reflection of that individual’s level of emotional maturity.

In our society, the right to enter into a marriage agreement is largely determined by chronological age. Our research problem began with the hypothesis that there is no direct relationship between chronological age and emotional maturity at the time of marriage.

For our study, marriages were divided into two general categories: 1) teenage marriages in which at least …

Life History Of Philophthalmus Megalurus (Cort, 1914) In Western Oregon, Toni Anne Mcmillan

Dissertations and Theses

The specific identification of a megalurous cercaria found in the snail Oxytrema plicifera was accomplished by completing the life cycle in the laboratory. This species is compared with the eastern Philophthalmus megalurus and P. gralli with which it was once confused. The eggs, miracidia, and rediae of the Oregon species were found to be similar to those of the above species. The body and organ sizes and sucker ratios for the cercariae and adult stages obviously indicate that the Oregon species is Philophthalmus megalurus.

An Interactional Approach To Weight Reduction, Carole T. Gygi

Dissertations and Theses

A treatment program was designed to enable subjects to lose weight through the use of self-confrontation as described in Saslow (1969), and the use of the General Relationship Improvement of the Human Development Institute (HDI), Berlin and Wyckoff (1964).

Self-confrontation is a programmed rehearsal of a specific problem by one person alone, for a five-minute period. The rehearsal, or self-confrontation is to be as vivid as possible, intellectually, emotionally, visually and physically.

The General Relationship Improvement Program is a 10-week text, worked in pairs, which is aimed at better intrapsychic and interpersonal communication and understanding.

Four matched groups were used …

The Effect Of Antibiotics On Thermophilic Blue-Green Algae, Erleen Blanche Christenson

Dissertations and Theses

The nature of the action of penicillin on the cell walls of bacteria is reviewed. The composition of bacterial cell walls is compared to cell walls of blue-green algae.

The test organisms used were thermophilic: Anacystis nidulans grew optimally at 35⁰C, whereas Synechococcus lividus grew best at 45⁰ C. Growth was recorded by reading optical densities.

Cells of these two thermophilic blue-green algae were treated with varying dosages of penicillin and streptomycin. Penicillin inhibited growth of Anacystis nidulans and Synechococcus lividus in concentrations of 3.0 µg/ml and 0.03 µg/ml respectively. However, when 0.3 µg/ml of penicillin was added to Anacystis …

Direct Design Of A Portal Frame, Angel Fajardo Ugaz

Dissertations and Theses

This investigation was undertaken to develop plastic design aids to be used in the direct design of optimum frames. It uses the concept of minimum weight of plastically designed steel frames, and the concept of linear programming to obtain general solutions. Among the special characteristics of this study are: A. The integration of both gravity and combined loading conditions into one linear programming problem. B. The application of the revised simplex method to the dual of a parametric original problem. C. The application of A and B above in the development of design aids for the optimum design of symmetrical …

Comparative Study Of Lightweight And Normal Weight Concrete In Flexure, Mohammad Zareh

Dissertations and Theses

This investigation represents a comparative study of the flexural behavior of lightweight and normal weight concrete. Both theoretical and experimental moment-curvature characteristics of the tested specimens were used to study the flexural behavior.

A generalized computer program to determine the moment-curvature relationships of a singly reinforced rectangular concrete beam was developed.

For this limited study it was observed that lightweight concrete beams when compared to normal concrete beams achieve comparable moment capacity (about 92% of normal weight concrete) but exhibit higher deflections (about 40% more than normal weight concrete).

An Analysis Of The Ability And Achievement Of Business Education Students Compared To Non-Business Education Students, William B. Warberg

Dissertations and Theses

Since some educators believe the underachiever and the low-ability student are frequently placed in business education classes for the purpose of finding him an easy way through school, this study attempts to determine just where the business education student actually ranks in achievement and ability as compared to students in other academic areas.

The students used in this study come from the graduating classes of 1969 and 1970 of Beaverton and Sunset High Schools in Beaverton, Oregon. A business education student has been defined as one who has successfully completed at least two of the following courses: Shorthand II; Office …

Foster Family Care For The Aged, Donald V. Sekora

Dissertations and Theses

The following was a research practicum instituted as an actual project for the State of Montana Welfare Department between June, 1970, and May, 1971. The project had a two-fold purpose in being conceived: one purpose was to fulfill a graduate school academic requirement; and the second purpose was to fulfill a responsibility to the people of Montana who would eventually gain some benefits from this project. The series of written documents that follow are the description of that project's conception and actualization in six Montana counties. The first part is the project idea and theory; the next two parts consist …

The Father's Role In Treatment: A Survey Of Selected Social Service Programs, Joanne Robertson

Dissertations and Theses

This is a descriptive, partially exploratory study which examined the date obtained from interviews with socials workers in selected social welfare programs in regard to the father in treatment. Explored were descriptive information concerning the agency's characteristics, the type and extend of treatment offered, the involvement or resistance of the father in therapy, and the provision made for a surrogate male model in the event of the father's absence.

The literature revealed that currently there is a growing body of knowledge and theory related to the father's role in the psychosocial development of the child and the consequences of his …
