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 …

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 …

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.

An Observational Study Of Service Provider Client Dyadic Interactions, Joan Dayger Behn

Dissertations and Theses

This dissertation reports on the evolution of an observation instrument designed to examine a series of dyadic interactions between service providers and elderly clients. The encounters took place in the physical context of the client's home and under the auspices of two different kinds of urban service agencies. Staff members and elderly clients of In-home Nursing and Interaction agencies participated in the study. The coding system (Service Provider/Client Dyadic Interaction Coding System or SP/CDICS), is comprised of 28 carefully defined and described behavioral categories. The categories were developed through literature reviews and a series of preliminary observations conducted in agencies …

Community Impacts On Organizational Interaction, Frederick Dalton Keast

Dissertations and Theses

This dissertation addresses the following research question. Do the criteria by which organizations assess the benefits of entering into interagency agreements vary by city? Employing data obtained from 183 human service agencies in six western cities, organizational emphases on two classes of goals as they relate to the decision to interact with other agencies are assessed as functions of six organizational variables and city. The organizational variables include organizational goal, reliance on federal sources for funding, and a range of environmental uncertainty measures. The two classes of organizational goals studied are: first, those which directly accrue to the agency itself, …

An Impact Evaluation Of Home Improvement Loans On Neighborhood Decline: The Case Of Portland, Oregon, Geri Larkin

Dissertations and Theses

Recently federal policy aimed at halting decline in urban neighborhoods has included a major focus on housing rehabilitation efforts. In the case of Portland, Oregon, federally funded improvement loans for owner-occupied housing units resulted in the rehabilitation of almost four thousand homes from 1975 until 1978, over twice the number of homes rehabilitated in any other city in the nation. The purpose of the present study was to examine and analyze the city's rehabilitation loan program in two ways. First, the loan process itself was examined to ascertain whether there were any deficiencies in the loan program which should be …

A Survey Of Carryover Practices Of Public School Clinicians In Oregon, Joan Marie Cranmer Polson

Dissertations and Theses

Clinicians report that carryover management is one of the most difficult and time consuming problems they face (Johnson, 1972) yet the literature offers little data to assist clinicians in determining what methodologies should be used and which are effective in facilitating carryover. The purpose of this investigation was to determine the type of methodologies utilized by public school clinicians in Oregon to facilitate carryover with clients originally diagnosed as having articulation disorders. A secondary question dealt with the perceived effectiveness of these methodologies.

Transport Of Ozone Across An Air/Water Interface Coupled With Aqueous Decomposition, Ahmad Ali Mehrabzadeh

Dissertations and Theses

Photoacoustic spectroscopy was used to analyze the transport of ozone through the air/water interface. Experimental results showed that the ozone transport rate is similar to rates measured for other gases of low solubility and low reactivity. The transport rate increases with increasing pH. The decomposition rate of ozone was studied in solutions. The decomposition rate also depends on the pH of the solution, and in high pHs both the deposition velocity and the decomposition rate constant of ozone have larger values. The value of the deposition velocity (Kd) is 3.7 ± .9 x 10^-3 cm/sec and the decomposition rate …

Toward A Test For Ethnocentrism And Ethnorelativism Based Upon Reference Group Orientation, James C. Mayer

Dissertations and Theses

The object of this investigation is to determine whether two aspects of reference group orientation, 1) multiplicity and 2) structural variation, are possible indicators of ethnocentrism. Most of the thesis is devoted to a theoretical formulation in which reference group orientation and ethnocentrism are placed in a peroeptual framework. Reference group orientation is defined as a person's use of a frame of reference that is formed through adoption of a reference group's perspective. Ethnocentrism is defined as a person's use of a frame of reference that keeps him from accepting the viability of other cultural frames of reference. The acceptance …

The Effect Of Costs And Constraints On The Optimum Employment Combination Of Full-Time And Part-Time Faculty At Urban Community Colleges, Zoe Annette Arrington

Dissertations and Theses

The labor market for part-time faculty at community colleges has changed such that in the past decade the number of instructors who teach part-time now outnumber those who teach full-time. This dissertation examines the full-time and part-time labor markets arguing that two separate labor markets exist. The supply in an urban area is nearly perfectly elastic for both full-time and part-time faculty; the demand side of the labor market is characterized by a number of costs. Data on costs were collected by two separate questionnaires, one to faculty and one to the personnel office of each college. The costs differ …

Patterns Of Information System Growth In Community Mental Health Centers, Linda J. Bellerby

Dissertations and Theses

This research was undertaken to determine whether the growth of computer-supported information systems in community mental health centers can be characterized by distinct stages of development. Data collection and analysis were designed to answer the following two questions: (1) Can distinct stages of information system growth be characterized by common profiles of computer-supported applications? (2) Are there characteristic groups of enabling factors (i.e., organization of data processing activities, management planning and control techniques, and user involvement) consistent among community mental health centers at any given stage of growth? This study draws upon earlier work by Nolan who identified distinct stages …

Age And The Comprehension Of Spatial Adjectives, Barbara Ann Cassidy

Dissertations and Theses

The purpose of this study was to determine the significance of chronological age on the comprehension of spatial adjectives in children. Specifically, the investigation set out to determine the age levels at which children comprehend the polar forms of various spatial adjectives and to determine the difference in age levels of comprehension of unmarked versus marked adjective forms. Seventy children between the ages of two years, +/-2 months and eight years, + 2 months, selected on the basis of chronological age, normal receptive vocabulary recognition and normal hearing, participated as subjects.

Public Transit And Student Choice : A Survey With Portland State University Students, Sheku Gibril Kamara

Dissertations and Theses

Research in urban transportation has been of many facets. Some have emphasized modes and routes while others have attempted to isolate and look at small segments of the transportation market with specific demands. Such segments include workers, recreation riders, and to a less extent, students. In the "journey-to-work" studies, a major finding has been that as income of workers increases, the distance between residence and work-place also increases.

This thesis starts with a series of hypotheses generated as a result of the findings of other studies reviewed in the literature. In testing the hypotheses, variables that are likely to influence …

Storage And Use Of Glycogen By Juvenile Carcinonemertes Errans, D. Mitchell Wolgamott

Dissertations and Theses

Morphological And Cytological Studies On Arceuthobium (Viscaceae) In Relationship To Host Phloem With Studies On The Healthy Phloem In Pinus Sabiniana (Pinaceae), Margaret Carol Alosi

Dissertations and Theses

Anatomical and developmental tissue relationships between Arceuthobium spp. endophytic tissues and host vascular tissues were examined by light and transmission electron microscopes. The host-parasite pairs studied were Psudotsuga menziesii/A. douglasii, Tsuga heterophylla/A. tsugense, Pinus sabiniana/A. occidentale, and P. lambertiana/A. californicum. The morphological form and growth characteristics of A. douglasii in different aged host tissues was found to be coordinated with growth and maturation of the host. It is proposed that morphological forms of Arceuthobium endophytic tissue be categorized as (1) primary, (2) diffuse-secondary, or (3) localized-secondary in order to semantically clarify the relationship of endophytic morphology with primary or secondary …

The Production Of Culture On The Oregon Federal Arts Project Of The Works Progress Administration, Carolyn Howe

Dissertations and Theses

This thesis addresses the relationship between art and society by examining the production of culture on the Oregon Federal Art Project (FAP) of the Works Progress Administration (WPA). The author examines the social conditions and decision-making processes which shaped the art that was produced and determined who produced and who consumed the art of the FAP. Also examined are the changing social relations of art prior tCI), during, and after the WPA's Federal Art Project. The research for the thesis utilized inductive methods of research aimed at theory construction rather than theory testing, although theoretical questions guided the gathering and …

Selective Reflection Of Light At A Solid-Gas Interface And Its Application, Fumihide Takeda

Dissertations and Theses

In order to study the detailed spectral intensity distribution of light reflected from a solid-gas interface, the extinction theorem in optics is extended to include an absorbing medium and the thermal motion of the gas molecules near the interface. The theoretical spectral intensity distribution in the region of anomalous dispersion is found to be strongly modified compared to that predicted by existing theory. An important consequence of this theory in the line shapes of the reflected light is the possibility of using recently developed saturation spectroscopic techniques to study atoms and molecules near surfaces. In order to investigate the feasibility …

Late Pleistocene And Recent Archaeology And Geomorphology Of The South Shore Of Harney Lake, Oregon, Keith Donald Gehr

Dissertations and Theses

The present study was a response to the discovery of two artifacts found in a ditch wall near Harney Lake, Oregon. These were lying on a buried lake floor that appeared to be of late Pleistocene or early Recent age. Other sediments exposed in the ditch seemed to relate to at least some of the phases of the pluvial lake sequence in the Harney Basin. Three problems were considered: (1) the geomorphology and dating of the pluvial lake stillstands, (2) whether the original artifacts were part of a larger early site, and (3) whether there was any relationship between archaeological …

Stability And Resilience In Business Systems, Donald Bard Wilcox

Dissertations and Theses

The purposes of this research report are (1) to introduce into financial management theory, the concepts of stability, resilience and steady state from general systems theory, (2) to formulate hypotheses about the relationships among rate of return, business risk, stability and resilience as exhibited by business systems, (3) to construct quantifiable surrogates for these concepts in terms of the financial operating characteristics of business systems and (4) to test the hypotheses with an appropriate statistical methodology. Business systems are investigated from two different perspectives or levels of aggregation. The first level treats each individual firm as the business system. The …

Studies Of Homogeneous Nucleation And Transient Heat Transfer In Cryogenic Liquids, Dipen N. Sinha

Dissertations and Theses

We report the results of a series of experimental studies in two interrelated areas: homogeneous nucleation and transient heat transfer in cryogenic liquids. We report the first determination of the homogeneous nucleation temperature of liquid helium I and liquid nitrogen employing a transient superheating technique. This technique in liquid helium involved the development of a new transient magnetoresistive thermometer which relies on the strong temperaure dependence of magnetoresistance in bismuth as a thermometric property. Our measurements of the homogeneous nucleation temperature for both liquid helium I and nitrogen are in good agreement with the predictions from the Becker-Doring Volmer-Zel'dovich-Frenkel nucleation …

Computer Aided Optimal Design Of Helical Gears, S. N. Muthukrishnan

Dissertations and Theses

A random search method for optimum design of a pair of helical gears has been developed. The sequence of optimization consists of two principal components. The first is the selection phase, where the output is the starting solution for the design variables - module, facewidth, helix angle and number of teeth on the pinion. The input for the selection phase includes the application environment, approximate center distance, minimum helix angle, desired values of gear ratio, pinion speed and the power to be transmitted. The limits on each of the design variables and the constraints are imposed interactively during the first …

Normative Data On The Auditory Memory Test Battery, Mary Clare Mountain

Dissertations and Theses

This study examined the means and standard deviations for the Auditory Memory Test Battery (Burford, 1976) using a sample of normal second, third, and fourth grade children. The study also compared span and sequence scores, low and high SES scores, and an individual's test scores with teacher judgment of intelligence group. A brief examination of the AMTB as used with LD children was also performed but not included in the statistical analysis.

Recall And Recognition Memory Under Varying Conditions Of Hypnotically Suggested Amnesia, Christopher R. Meagher

Dissertations and Theses

Posthypnotic amnesia has been systematically investigated in the past and subsequently alluded to as either role enacted behavior or evidence for an altered state of consciousness. Recall and recognition have been tested during posthypnotic amnesia and as in normal memory functioning, recognition performance has been found to be usually superior to recall performance. In order to gain further understanding of the circumstances which facilitate amnesic behavior, an experiment was carried out which was designed to vary the usual manner in which recall and recognition memory are observed during posthypnotic amnesia.

Surface Area Of Coal As Influenced By Low Temperature Oxidation Processes, Salvador Leon Arredondo

Dissertations and Theses

The possibility of increasing the amount of readily accessible surface area by enlarging the 5 A pore was examined via pretreating the PSOC-371 coal with gases such as nitrogen, nitrogen-oxygen, and ozone-oxygen and hydrogen peroxide solutions. Surface areas were obtained from nitrogen adsorption at 77 K and carbon dioxide adsorption at either 298 or 195 K for each sample before and after treatment.

Population Dynamics Of Nonmetropolitan Cities In Five Western States, Peter Carlton Munroe

Dissertations and Theses

Contrary to popular belief, small cities, located outside Standard Metropolitan Statistical Areas (SMSA's) and generally referred to as nonmetropolitan cities, have not been declining in population and withering away; rather, they have been growing and prospering in all regions of the country, albeit their growth varies considerably.

It is this variation in growth rates of nonmetropolitan places in the northwest (and the factors associated with this variation) which is the focus of this thesis. Research literature in this area indicates a reciprocal relationship between the nature of economic activities in nonmetropolitan cities and their growth patterns. In an attempt to …
