The Ductuli Efferentes In Macaca Mulatta: Electron Microscopic Evaluation Of Changes After Vasectomy, Loyal Douglas Marsh

Dissertations and Theses

After vasectomy, the passage of sperm antigen through the epithelium of the efferent duct in the rhesus macaque probably results in immune complex deposition. Immune complexes can be visualized in the thickened basement by fluorescence microscopy. Subsequent electron microscopic evaluation, with the appearance of electron-dense deposits in the basement membrane of the efferent ducts, substantiates these findings.

A Cognitive-Behavioral Approach To The Control Of Dream Content, Gary Nick Dean Lehto

Dissertations and Theses

A cognitive-behavioral technique for developing dream control was examined. Twenty paid subjects were randomly assigned to either an attention-placebo control group or a cognitive-behavioral training group. Subjects met in the respective groups for a total of three hours of "training." Subjects in the actual training group were presented with a self-instruction sequence to practice and use in attempting to manipulate dream content. The control group subjects met to only discuss dreams and dreaming and were given no specific instruction in content control. After completion of the training, each subject individually spent two consecutive nights in a sleep laboratory. The first …

Buddhistische Elemente In Hermann Hesses Siddhartha, Sawitree Kunapongsiri

Dissertations and Theses

The purpose of this thesis is to show the elements of Buddhism, exerted in Siddhartha. These elements are important to the plot, despite the fact that Hesse did not intend to write an authentic Buddhist work, but to express his own belief.

The study was designed to determine the degree to which a group of normal hearing college students could recognize words and phrases …

Electrostatic Tem Studies Of Magnetic Domains In Thin Iron Films, Hideaki Karamon

Dissertations and Theses

An electron microscope with electrostatic lenses was used for high resolution studies of magnetic domains in thin iron films.

Observation methods used to determine the directions of local magnetization in iron thin films were the Lorentz method and the Foucault method.

We studied how Bloch line-crosstie pairs and crosstie main walls behave in applied, in-plane magnetic fields. We found that crosstie main walls remain unchanged until crosstie density goes nearly to zero when the field is applied perpendicular to the main wall. A twisted type of domain appears where crossties disappear.

A Cross-Cultural Study Of Role Behaviors Pertaining To The Roles Of Student And Professor, Kathryne Jeanne Nadal

Dissertations and Theses

Communication theory involving the role concept has shown that role expectations and differing evaluations of role behavior can lead to communication breakdowns between persons. Literature pertaining to relations between professors and international students indicates the presence of unfulfilled expectations between them as to how they perform their respective roles. It was therefore hypothesized that some difficulties international students face in the academic world may be due to factors such as differing role expectations. As the literature provided no methodologically based cross-cultural research in this area, the researcher undertook to discover if professors and students evaluate the roles of student and …

An Analysis Of Gravity Surveys In The Portland Basin, Oregon, Janice C. Perttu

Dissertations and Theses

The geologic setting of the Portland Basin is ideal for gravity surveys because of the large density contrasts between geologic units. The Portland Basin consists of a north-northwest-trending syncline in the Columbia River basalt overlain by Pliocene to Recent alluvium. This study was undertaken to define structures in the Portland Basin which are obscured by the alluvium.

An areal gravity survey of the Portland Basin covering approximately 450 square kilometers was conducted for this study.

A Comparison Of Spanish Language Samples Elicited By The Investigator In The Clinic And By The Mothers In The Home, Soledad Chavarria Navas

Dissertations and Theses

The primary purpose of the present study was to compare the quality of spontaneous language samples elicited from twelve low socioeconomic, normally developing, migrant Spanish-speaking subjects by their mothers in the home and by this investigator in the clinic. The subjects ranged in age from three years, one month to six years, nine months.

The essential question sought to determine if the comparison of language samples elicited in the home by the mothers and the language samples. elicited in the clinic by the investigator yielded significant differences in syntactical language development as measured by the Developmental Assessment of Spanish Grammar …

Cytologic Characterization Of Human Constitutive Heterochromatin, Timothy Atchison Donlon

Dissertations and Theses

A study was conducted to cytologically map certain subsets of constitutive heterochromatin onto specific portions of human chromosomes. This involved sequentially staining metaphase chromosomes from lymphocytes first with the Centromeric Dot, Giemsa-11, G-banding or Lateral Asymmetry staining techniques, which are cytochemical methods which stain particular chromosomes or chromosomal regions. Then those same metaphase chromosomes were stained using the C-banding technique, a method which is believed to denote constitutive heterochromatin. With the exception of the G-banding technique, areas depicted by the special staining techniques were found to reside only within the areas stained by the C-band technique and are thus believed …

The Degree Of Acculturation And Success Patterns In Three Generations Of The Japanese Americans In The Portland Area, Toshimasa Fujii

Dissertations and Theses

Past research shows that Japanese Americans have been successful occupationally, financially and educationally. This thesis examines factors leading to this success. It is generally argued that the greater the congruence between minority and majority value systems, the less likely conflict would be generated in the minority group's acculturation. There appear to be two opposed aspects in the acculturation of the Japanese Americans, relinquishment or retention of traditional Japanese values. Also important is the degree to which Japanese Americans identify themselves as American, or Japanese, or some mixture. This thesis focuses on the following questions: What types of values have been …

A Comparison Of Three Measures Of Waking Fantasy, Carey Sue Edney

Dissertations and Theses

This project compared three techniques of assessing waking fantasy, or daydreaming. The Thematic Apperception Test (TAT), the Imaginal Processes Inventory (IPI), and time-sampled ongoing mentation reports (OMR) were the three measures employed. Seven qualities were compared, as measured by the three methods, using a multitrait-multimethod correlation matrix. Neither extensive convergent nor extensive discriminant validity was demonstrated among the three measures. This suggests that one should use caution in comparing research findings which utilize different measures of waking fantasy.

Das DreiecksverhäLtnis In Gerhart Hauptmann's "Einsame Menschen" Und "Gabriel Schillings Flucht" Und Dessen LöSung Im Naturalistischen Drama, Ulrich Karl Tutsch

Dissertations and Theses

Die bürgerliche Gesellschaft des ausklingenden 19. und beginnenden 20. Jahrhunderts drängte fast einen jeden Menschen in eine Aussenseiterrolle, wenn er ihre Werte nicht akzeptierte. Der Naturalismus machte innere Schwächen der Menschen wie auch deterministische äussere Einflüsse für das Scheitern der Hauptfiguren verantwortlich.

Johannes Vockerat und Gabriel Schilling fühlen sich von ihrem bürgerlichen Familienleben eingeengt und versuchen mit Hilfe einer anderen Frau, ihr Dasein zu verbessern. Vockerat versucht dem Dreiecksverhältnis auf einem höhere geistigen Niveau gerecht zu werden. Er muss sich aber am Ende eingestehen, dass solch eine platonische Verbindung auf die Dauer unmöglich ist. Sein Ideal …

The Swamp Land Act In Oregon, 1870-1895, Richard Mark Pintarich

Dissertations and Theses

The Swamp Land Act of 1849, originally intended to give the state of Louisiana the unproductive swamplands within its borders and use the proceeds to construct the drains and levees necessary to reclaim these lands, was extended to Oregon in 1860. Oregon did not act on the matter until 1870, but once begun, it became a prolific source of political corruption, fiscal irresponsibility, fraud, and land speculation and monopolization. Even though the physiography of Oregon was much different than the states in the Mississippi Valley, millions of acres of "swampland" were filed upon and the state sold hundreds of thousands …

Effective Force Constant Ratios: Iron In Iridium And Rhodium, Dennis Munsterman

Dissertations and Theses

Classical methods of analyzing heat capacity data for the characteristic moments of the frequency distribution are applied to iridium and rhodium. Impurity moments are determined from high and low temperature f values. These moments are combined by modern theory to estimate the magnitude of the host-host to host-impurity force constant ratio. Ratios of the various host moments are also examined.

Art Therapy As A Mechanism For Increasing Life Satisfaction In Later Life, Phyllis Laulainen Mcgraw

Dissertations and Theses

It was hypothesized that art therapy with the elderly would increase the quality of an informal life review and motivate them toward greater psychological well-being (life satisfaction). To test this hypothesis, 30 subjects between the ages of 61 and 83 were assigned to three experimental conditions: Art Therapy Group, Discussion Group, and Control Group.

Comparison Of Two Receptive Language Tests (Ppvt And Tacl) Used With The Developmentally Delayed, Paul H. Lamb

Dissertations and Theses

The purpose of this investigation was to compare the results as recorded in mental ages of the PPVT and TACL when used with developmentally delayed children. One aspect was to observe how well the mean mental age from each test would compare with the mean mental age obtained from psychometric testing (WISC-R or SB-LM results). Another aspect was to determine how well the data from the PPVT and from the TACL would correlate with the psychometric testing results.

A Comparison Of The Effects Of Paced Practice And Progressive Practice Skillbuilding Procedures On The Development Of Straight-Copy Speed And Accuracy In Beginning Collegiate Typewriting, Bonnie Sue Shannon

Dissertations and Theses

The problem of this study was to determine the effects of progressive practice skill building procedures and paced practice skill building procedures upon the straight-copy typewriting achievement of students enrolled in first-term collegiate typewriting. The procedures were compared on the bases of the dependent variables: 1) straight-copy stroking speed, and 2) straight-copy accuracy. The following null hypotheses were tested:

1. There will be no significant differences in the straight-copy stroking speeds achieved by students participating in progressive practice skill building procedures and students participating in paced practice skill building procedures.

2. There will be no significant differences in the straight-copy …

Comparisons Of Videotape Observation To Direct Observation, John W. Hanlan

Dissertations and Theses

This research examined the validity of videotaped analyses of clinical sessions in comparison to direct (live) observations. The subjects were eleven student clinicians and their respective clients, enrolled Fall Term, 1979, in Portland State University's Speech and Hearing Sciences Articulation and Language and Urban Language Clinics. The Boone-Prescott Interactional Analysis System, a numerically coded system, was used to record clinician/client interactions. Data were obtained for a randomly selected five-minute period from each of thirty clinical sessions.

The Effect Of Residual Stress Distribution On The Ultimate Strength Of Tubular Beam-Columns, Steven L. Barrett

Dissertations and Theses

Using data for the longitudinal residual stress distribution in welded steel tubes, curves describing these distributions are selected for study. Each of these curves are checked for static balance across the tube cross section. The curves that exhibit an imbalance are adjusted by a combination of a simplified model for each and the use of a computer program that is developed to calculate the resulting forces and moments on the cross section. The residual stress in the area of the tube wall opposite the longitudinal weld is found to be the most important in the adjustment to obtain exact equilibrium. …

The History Of Community Theatre In Anchorage, Alaska, 1946-1976, Robert Pond

Dissertations and Theses

This investigation sets forth the history of community theatre in Anchorage, Alaska and proposes to define a future role direction made necessary with the advent of professional theatre in the community.

By 1976 the Community Theatre movement in Anchorage found itself in direct competition with the professional performing programs for the limited performing space, subsidies, and audience. For the Community Theatre to continue functioning, a re-definition of non-professional theatre in Anchorage had to be found.

Reduction Of Capacitor Switching Transients By Controlled Closing, John Herman Brunke

Dissertations and Theses

This thesis presents the theory, analysis, testing and implementation of a scheme to reduce shunt compensation capacitor switching transients. The described method is switch the capacitors very near the instant when the bus voltage is at a power frequency zero. This was accomplished with a vacuum breaker on a 230 kV shunt capacitor bank.

Non-Linear Behavior Of Unbraced Two-Bay Reinforced Concrete Frames, Mehdi Shadyab

Dissertations and Theses

In this investigation, the primary objective was to study the nonlinear behavior of unbraced two-bay concrete frames and to determine the extent to which ultimate load theory or limit design can be applied to these structures. The frame behavior was investigated analytically by two methods. In the first method the frame stability equation was derived assuming that members of the frame possess an elasto-plastic moment-curvature relationship. This stability analysis was also carried out by another model consisting of a column attached to a linear spring and carrying the total frame load. The second method was through a computer program which …

The study area is composed of Eocene age sedimentary and volcanic units which were deposited in a filling basin. The lowest units were deposited in moderate to deep marine waters; the uppermost were deposited subaerially.

Stratigraphy And Sedimentation Of The Spencer Formation In Yamhill And Washington Counties, Oregon, Fathi Ayoub Al-Azzaby

Dissertations and Theses

The Spencer Formation in Yamhill and Washington Counties, Oregon, is exposed in a narrow belt 27 km long, from 1/4 to 3 km wide and with a maximum thickness of about 400 m. The formation is composed entirely of sandstone with interbedded thin layers of mudstone in the uppermost member. The sedimentary structure and paleoecology indicate a shallow marine depositional environment. The upper member of the Spencer Formation contains more quartz, plagioclase, and hornblende than does the lower member, but K-feldspar is less than that of the lower member. Shallower water conditions for the deposition of the upper member are …

The Structure And Stratigraphy Of The Columbia River Basalt In The Chehalem Mountains, Oregon, Abdul-Rahman Mohammed Al-Eisa

Dissertations and Theses

The Chehalem Mountains area, encompassing 70 square kilometers, is at the western extent of the Columbia River Basalt Group as mapped in western Oregon. The flows in the study area were identified as belonging to subdivisions of the Columbia River Basalt Group on the basis of physical characteristics and trace element geochemistry. The basalt flows are poorly exposed in the area and weathering is deep and extensive where the flows have been exposed. Where erosion has exposed the underlying marine sedimentary rocks, the basalt has failed in landslides.
