Distribution And Ecology Of Great Blue Heron Colonies On The Willamette River, Oregon, Scott M. English

Geography Faculty Publications and Presentations

In the United States there is breeding ecology information available on the Great Blue Heron (Ardea herodias), but large-scale distributional and productivity information is lacking. In the lake regions of the Canadian provinces of Alberta, Manitoba, and Saskatchewan, regional surveys of Great Blue Heron nesting sites have been done by Vermeer and Reynolds (1970) and Vermeer (1969). Breeding biology studies were done in California (Pratt 1970, Page 1971), Canada (Vermeer 1969, McAloney 1973), and Oregon (Henny and Bethers 1971). In 1974 a survey of Great Blue Heron heronries on the Oregon Coast was completed through a National Science …

Prehistoric Mobile Stone Sculpture Of The Lower Columbia River Valley: A Preliminary Study In A Southern Northwest Coast Culture Subarea, Marilyn Sargent Peterson

Dissertations and Theses

This study presents a preliminary compilation of 1) archaeological sites or geographic locations in the lower Columbia River valley where mobile prehistoric zoomorphic and anthropomorphic stone sculptures have been found, 2) a descriptive listing of the sculptures found at each of these sites or locations, and 3) insofar as possible an evaluation of the significance of these sculptures in the culture history for the area. Such an evaluation is based primarily on evidence derived from archaeological, ethnographic and historic contexts wherever they can be ascertained. However, the evaluation is also based upon a general analysis of the inherent design characteristics …

Political Activities Of Professional Social Workers Residing In Portland, Oregon, Connie May Henes

Dissertations and Theses

In order to assess political activity levels of Portland social workers, thirty Master of Social Work (M.S.W.) social workers were interviewed according to a structured questionnaire. The members of the sample were selected from National Association of Social Workers, Oregon Chapter membership and from selected public social service agencies.

The results showed, in comparison to previous research findings of Lester Milbrath and Julian Woodward, that Portland social workers are more politically active and knowledgeable than hypothesized. Portland social workers were found to be largely Democrats. The most politically active social workers were found to be those who are employed in …

A Comparative Study Of The Resettlement Status Of Indochinese Refugees In Portland, Rosalynn R. Ringor, Chareundi Van-Si, Steven Hernandez

Dissertations and Theses

This study sought to explore the resettlement of Indochinese refugees to their new life in Portland, Oregon. Three basic areas were under consideration. The first area dealt with demographic data: who are the refugees and what are their pasts? The second area focused on aspects of successful resettlement: what do refugees seek in order to consider themselves successfully resettled, and how do their ideas of successful resettlement collate with their present state of resettlement? The third area dealt with the effectiveness of resettlement programs: how have various assistance programs been helpful to the refugees, and are the refugees aware of …

Native American Social Work Symposium : An Evaluation, Lou Stone

Dissertations and Theses

The inconsistencies of the state and federal policy toward Native populations and additionally those inconsistencies within the two governments themselves, require the maintenance of Indian and Alaskan Native organizations with sophisticated mechanisms developed to advocate “reforms” in Indian services to meet unique Indian needs.

Indian and Alaskan Native social workers invariably find themselves at the confluence of client service provision and surviving the extension of policies available to them from resource allocators for the purpose of service provision. In order to approach this dilemma, the Native American Social Work Symposium, held in May of 1977, convened on the basis of …

An Experimental Investigation Of The Hole-Drilling Technique For Measuring Residual Stresses In Welded Fabricated Steel Tubes, Chau Mong Tran

Dissertations and Theses

Among semi-destructive methods of measuring residual stresses in elastic materials, the blind hole-drilling strain-gage method is one of the best because it is simple, economical and accurate. It is based on the measurement of strains disturbed by machining a small diameter shallow hole in the test piece. The strains measured in three known directions permit the determination of the direction and magnitude of principal stresses and subsequently of any stress in any direction.

This thesis presents the investigation of residual stresses in the longitudinal direction of a welded fabricated steel tube of 22 inch diameter, relating to a series of …

An Investigation Into The Elasticity Of Demand For Motor Gasoline, Samy Fouad El-Iskandarany

Dissertations and Theses

This thesis investigates the existence and determinants of the elasticity of demand for motor gasoline.

The research can be divided into four main stages. In the first stage, time series data of fifteen member countries of the Organization for Economic Cooperation and Development (OECD) are analyzed.

The ratio of gasoline price per gallon to the per capita GNP is introduced in this research to explain the variability in the size of the price elasticities of demand over the various countries. The ratio is called the "Price Factor" and designated as P.F. The introduction of P.F. established the basis for meaningful …

Light Extinction In Polydisperse Particulate Systems, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

Analytic methods are developed for determining the attenuation characteristics of light beams propagating through ensembles of scattering particles including those with complex index of refraction. The methods are applicable to a wide range of practical particulate systems, and the results are expressed explicitly in terms of elementary functions. Propagation through fog and clouds is considered as an example, and it is found that absorption by the liquid lengths. water in such ensembles affects strongly the extinction for ir wave-lengths

Assessment Of Feasibility Of Proposed Bolted Connections For Tubular Structures, John Henry Tausch

Dissertations and Theses

The search for new and additional sources of energy -- from sun, wind, waves, and ocean currents -- is necessitating the development of structures in the open environment of the oceans as well as on land. The advantages of round or tubular members for use in such structures are shown; and to avoid the uncertainties of welded joints, two bolted connections are proposed and their feasibility explored.

Wages, Welfare, Or What? [Statement Of Norman L. Wyers] - Salem, Or, Norman L. Wyers

School of Social Work Faculty Publications and Presentations

In his testimony to joint hearings before a task force of the welfare reform subcommittee of the US House of Representatives held on November 9, 1977, in Salem, Oregon, as part of a proposed welfare reform bill, H.R. 9030, Professor Norman L. Wyers shared the diverse opinions of participants of Oregon town hall meetings on economic security, entitlement, eligibility and responsibility. The public opinion survey findings revealed Oregonians' support for humanitarian policies, universal benefits, and a focus on job creation over training. Wyers urged policymakers to consider the liberal attitudes uncovered in the survey, emphasizing the need for a steady …

Netarts Bay, Oregon: An Assessment Of Human Impact On An Estuarine System, Larry D. Mccallum

Dissertations and Theses

Problems associated with planning the future use of estuarine areas stem from:

1. A lack of knowledge on the critical aspects of the system.
2. Inability to predict the future changes which will occur within the system in order to effectively manage the resource base.

These difficulties lie in the fact that changes within the system occur because of both "natural" and "cultural" conditions. The thesis hypothesis and subsequent research is to describe the physical changes that have occurred within the Netarts system, primarily due to man's impact.

Types of data gathered for the analysis includes that on historical and current land …

The Development And Testing Of A Fluidic/Pneumatic Position Servo, David Lyle Portin

Dissertations and Theses

This thesis reviews the design and analysis of a fluidic/pneumatic position servo. Rolling diaphragm piston actuators are used for the system drive, and a hydrostatic gas journal bearing is used as the position sensor. The servo has a 1 inch range which is monitored using an electrical capacitive position transducer that was built as an integral part of the system.

Open-loop frequency response testing provides the basis for a mathematical model of the system.

The servo response is linear at frequencies up to 3 Hertz.

The frequency response appeared to be limited by the design of the gas bearing sensor, …

Error Codes In Digital Data Communication Systems, Robert Hadley Cravens

Dissertations and Theses

Today’s digital communication systems perform data transfers at the rate of millions of bits per minute, with data errors in the order of 1/6th error per day. This magnitude of errorless communication is now possible because of sophisticated error correcting codes. Many types of error codes are employed today in three distinct areas of digital data communication: human to computer; data source to computer; computer to computer; and intra-computer; we are concerned here with intra-computer communication.

This research is primarily a mathematical study of error codes in general to explore the possibilities of each major type for the purpose of …

Limit Design Of Unbraced Reinforced Concrete Frames, Thomas Joseph Gavin

Dissertations and Theses

The main objective of this study was to determine whether Limit Design could be applied to low-rise unbraced concrete frames. The investigation was carried out both analytically and experimentally.

In the analytical part, two mathematical models were used to determine the behavior of unbraced frames. The first method used a nonlinear computer program, which takes into account the material and geometric nonlinearities of concrete frames. Several cases of frames with different reinforcement ratios and under different beam to column load ratios were investigated. For each frame the gravity loads were increased proportionately to 3/4 of the ultimate frame capacity. Then, …
