Design Of A Microprocessor Controlled Telecommunication System, George J. Maroutsos

Dissertations and Theses

Recent advancements in Large Scale Integration Technology have made available devices, such as microprocessors, analog gates and "three state" logic, that provide the designer with a wide range of possibilities in the design of telecommunication systems. A microprocessor and analog gates are utilized in this design to demonstrate the feasibility of implementing a flexible Telecommunication System. The microprocessor is programmed to control, through software, the system functions. The feasibility of systems highly adaptable to the needs of individual subscribers is thus demonstrated.

Beam Modes In Complex Lenslike Media And Resonators, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

General sets of higher-order beam modes are derived for light propagation in media having spatial variations of the gain or loss. The resulting expressions are also valid for propagation through conventional optical elements and graded transmission filters. The four basic mode sets obtained include off-axis Hermite-Gaussian and Laguerre-Gaussian modes of both real and complex argument. A procedure is developed for finding the resonant modes of laser oscillators containing arbitrary complex lens elements, and the mode stability properties of lasers can be interpreted physically by means of these formulas.

Political Development In Oregon: The Provisional Government 1843-1849, James M. Tompkins

Dissertations and Theses

This study brings together in a single volume facts and opinions not previously consolidated on the subject of Oregon's provisional government.

The main areas of concentration in the thesis include the political events of the government in session and the public's knowledge of these events. Also examined are the direction of government, the electoral process, and the newspaper coverage of the period.

The extant journals of the government are the primary sources for the proceedings of the sessions. Public opinion and awareness …

Some Aspects Of The Ecology Of The Virginia Opossum (Didelphis Virginiana Virginiana Kerr 1792) In An Urban Environment, David Hopkins

Dissertations and Theses

Eighty-three Didelphis virginiana from the Portland metropolitan area were collected and studied from December 1974 through May 1976. Males averaged 3394 g, females 2318 g. An annual sex ratio of 68.7:31.3 was recorded. Data indicate the possibility of a year-round breeding season and suggest the occurrence of three peaks of reproductive activity: January-February, April-May and October-November. The six primary foods consumed annually are: leaf litter, mammals, gastropods, earthworms, grasses and pet food. Seasonal composition and diversity in the diet is marked. Five new parasite-host records were established. These include mites: Androlaelaps fahrenholsi, Haemogamasus nidi, Eulaelape stabularis tick, Ixodes angustus, and …

An Aspect Of The Process Of School Desegregation: The Effects Of Reading Ability Grouping On Social Attractiveness And Peer-Perceived Success, David A. Johnson

Dissertations and Theses

Research on the effects of school desegregation has failed to produce conclusive findings. An over emphasis on the outcomes of school desegregation, usually assessed through the use of standardized test scores, has created a situation in which there exists a paucity of studies of the day to day process of school desegregation: instructional practices, student interaction, and teacher behavior in the classroom. More research on the process of school desegregation is needed if its results or outcomes are to become more interpretable.

The Columbia River As A Barrier To Gene Flow In The Vagrant Shrew, Sorex Vagrans Vagrans Baird, James J. Kirk

Dissertations and Theses

Twenty-one morphological characters were measured in shrews from four islands in the Columbia River and from the adjacent Oregon and Washington shores. Information on the history and characteristics of the river islands was gathered to facilitate interpretation of the shrew’s morphology data. Significant differences between character means of different populations were detected and average taxonomic distances between pairs of populations were calculated. The Columbia River is an incomplete barrier to gene flow, but its influence has been sufficient to allow divergence of island populations. Natural selection on the small gene pools of island populations has probably contributed to the divergence. …

Volunteers In Portland Schools: Initial Planning And Early Development, Mary B. Norville

Dissertations and Theses

The subject of this thesis focuses on the early development of Volunteers in Portland Schools. Commonly referred to as VIPS, this program was designed to coordinate and optimize the use of volunteers throughout the school district. VIPS is jointly sponsored by the Portland Public Schools and the Portland Council, P.T.A . and is funded by the Portland Public Schools.

The VIPS concept was conceived by the author of this thesis in August 1968. A proposal for a cooperative school volunteer progrcnn was written in the fall of that year with the endorsement of the School Board and the assistance of …

Exploring Collaboration: A Program Evaluation Of A Mental Health Intervention In A Public Elementary School, Joy Rhodes

Dissertations and Theses

The purpose of this evaluative study was to develop and implement a program evaluation design for a model of early mental health intervention to primary grade level classrooms in a public elementary school. The design reflects a formative evaluation study, providing information for current and future programming and is manageable to implement, thus facilitating longitudinal data collection.

This therapeutic model of classroom intervention stresses the integration of children’s social, emotional and intellectual development and proposes a collaborative approach between therapist and educator. Levels of intervention for collaborators include (1) children identified as requiring therapeutic approaches to social-emotional difficulties experienced in …

Theoretical Differences In Kissinger And Schlesinger's Models Of The International System, Wayne Alan Schroeder

Dissertations and Theses

This thesis is a study of national security decision making in the Ford Administration. The subject for study is the Kissinger- Schlesinger controversy in the Ford Administration. The thesis will attempt to prove that the differences that emerged over issues of national policy were due to deep theoretical disagreements as to the nature of the international system, the utility of power in the nuclear age and the means by which to preserve detente.

An examination of the substantive policy differences will be preceded by an examination of the conceptual disagreements between the Secretaries on topics that are fundamental to any …

The Effect Of Visual Feedback On Vocal Pitch Matching, Anita R. Herron

Dissertations and Theses

A review of the literature on the inaccurate singer provided strong evidence that improvement in pitch matching skill was possible. Visual feedback was found to be an effective aid in earlier studies, but none of the previous studies provided both a comparison group which had identical practice without the visual cues and a control group which received no form of practice. Such a design was used in the present study.

Thirty students at Portland State University who claimed to have considerable difficulty carrying a tune were given the opportunity to try to match Individual pitches under one of three conditions …

An Examination Of The Interrelationship Between Caregiver Behaviors, Infant Temperament And Perceptual-Cognitive Development, Anita E. Stauffer

Dissertations and Theses

The present study extended the Lewis and Goldberg (1968) study and included the parameter of infant temperament as defined by Thomas, Chess, Birch, Hertzig and Korn (1963). As in the Goldberg study, the index of response decrement was used as a measure of the infant’s development. It was hypothesized that response decrement would be positively correlated with high frequency of caregiver stimulation and negatively correlated with high infant intensity and activity ratings. Response decrement is the measured decrease in the amount of time an infant looks at a novel stimulus after several trials. It was computed by observing the infant’s …

Chlorine Distribution In The Idaho Batholith, Laurence Stewart Istas

Dissertations and Theses

Chlorine is thought to play a major role in the mobilization and concentration of base metals in the formation of ore deposits. The regional distribution of chlorine in the Idaho Batholith was studied to see if this could be related to mineralization or metallic provinces. One hundred forty-eight whole-rock samples, mineral separates, and standards were analyzed for chlorine by x-ray fluorescence.

The expected concentration of chlorine in the biotite fraction was not found. The chlorine was not significantly water leachable from the whole rock samples following normal grinding. The Idaho Batholith as a source for mineralizing chlorine was not established. …

Does Urban Noise Represent A Hazard To Health?, Frances J. Storlie

Dissertations and Theses

The problem of noise as a potential health hazard to urban man has been raised. The literature was used to establish two premises: that cities are noisy environments, and that noise-free societies have less coronary artery disease (CAD) than do industrialized sections of the world. These differences also hold for rural and urban areas of the United States.

Geographical questions concerning rate differentials for CAD have been addressed by numerous disciplines. Subsequently, social, psychological, and physical explanations have been put forth. Throughout this paper the emphasis has been placed on the physical aspects of noise exposure. The conceptual frame utilizes …

Depression And The Perception Of Reinforcement: A Modified Replication, Adele Gillis

Dissertations and Theses

The present study was a modified replication of Miller and Seligman’s (1973) study. Expectancy ratings under skill and chance tasks were examined in 51 college students in four groups: depressed high-external, depressed low-external, nondepressed high-external, and nondepressed low-external. The major hypothesis predicted that there would be greater association (1) between both magnitude and direction of expectancy change and outcome of the previous trial (success/non-success) with nondepression than with depression, under the skill task, (2) between both magnitude and direction of expectancy change and outcome of the previous trial (success/non-success) with low-externality than with high-externality, under the skill task, and (3) …
