A Descriptive Study Regarding Perceptions Of Sex Roles In Cooperative Households, Emily Fultz, Billie Huntwork

Dissertations and Theses

The roles of men and women are among the many elements of contemporary American society which are in a process of rapid and sometimes disruptive change. The more or less traditional ways in which men and women have viewed themselves and each other are being openly challenged by a number of significant factors. Although there have always been those exceptional persons who questioned the inevitability of seemingly given role differentiation, today's social climate makes such questioning more common and acceptable.

A few specific factors may be mentioned as being particular interest. With modern communication and mobility, the options for varied …

An Automatic Rinse Tank Controller For Industrial Applications, Aliasghar Emami

Dissertations and Theses

This thesis describes an automatic Rinse Tank Control System used in detection and removal of contaminating agents from industrial plating rinse tanks. It automatically monitors the purity of the rinse water in sixteen separate rinse tanks, and permits fresh water to enter the tanks only when the conductivity of the rinse water in each tank exceeds a predetermined level. Its use will result in large savings in consumption of fresh water and the subsequent reduction in discharge of effluent to the treatment plants.

Differential Measurement Of A Language Concept Presented Via Video Tape Playback To First Grade Students, Richard Warren Trullinger

Dissertations and Theses

Educational television began in 1932 at the State University of Iowa. Until 1952, the potential of its contributions to education were not fully recognized. In 1952, however, the Federal Communication Commission created non-commercial television station. From that point in time, educational television has mushroomed.

This study tested the hypothesis: At least 80 percent of a given first grade population will respond accurately to the post-testing of a language concept, after the concept has been presented to them via a video tape playback using puppetry as the teaching method. In essence, the study was designed to determine whether or not an …

Danish Day Care As A Social Institution, Albert Sessions Belais, Ellane L. Kibel

Dissertations and Theses

A study of the social and cultural aspects of day care in Denmark. The thesis hypothesizes that experiences in the development of Danish day care are relevant to the future development of day care in the United States.

Interest in Danish day care was stimulated by the reports of Drs. Marsden and Mary Wagner (1970) which found Danish day care provided an intimate and innovative standard of care for young children.

Twenty centers of widely varied types were visited in Denmark. Information was gathered largely through unstructured interviews with child care staff and non-participant observation. Special attention was paid to …

The Digital Multifunction Power Measuring System, Ralph Warren Shoemaker

Dissertations and Theses

The Digital Multifunction Power Measuring System is the outgrowth of a project involving the design of a prototype precision Digital Watt Transducer for the Bonneville Power Administration (BPA). A prototype Digital Watt Transducer was built and tested since no other device of the desired accuracy was commercially available. Upon partial completion of the project, another Watt Transducer did become available which was essentially identical to our development. Since we could not economically compete with the manufacturer of these Watt Transducers, our project was stopped. Over a period of several months we thought about other ways to apply the experience gained …

The Costs Of Sprawl: Environmental And Economic Costs Of Alternative Residential Development Patterns At The Urban Fringe , Real Estate Research Corporation

Portland Regional Planning History

Local government officials devote a large proportion of their time to considering and acting upon development proposals which substantially affect their communities in many ways. While information bearing on development proposals has been increasingly broader in scope, more specific, and of higher quality, local government officials continue to have considerable difficulty in assessing the relative merits of alternative types of housing, general development patterns, and commercial strip versus center developments. To help compensate for this knowledge deficiency, the Council on Environmental Quality (CEQ), in cooperation with the Department of Housing and Urban Development (HUD) and the Environmental Protection Agency (EPA), …

Output Properties Of Short-Pulse Gain-Switched Lasers, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

A formalism is derived for analyzing the spectral and temporal properties of gain-switched lasers. The development of the longitudinal mode structure from spontaneous emission, limiting linewidths, and over-all spectral characteristics are considered in detail; and applications are discussed.

Intelligibility Of Speech Compared Through Two Limiter Compression Circuits, Lee M. Odell

Dissertations and Theses

Hearing aid manufacturers commonly engineer automatic gain control (AGC) circuits which are aimed at reducing sound tolerance problems and improving speech intelligibility among wearers. The most common type of AGC engineered is one utilizing a fast attack time. The present study was designed to evaluate the effects of both fast and slow attack times on the intelligibility of speech. Twenty-four normal hearing subjects listened to sixty pre-recorded sentences through two types of hearing aid circuits. Thirty sentences were modified by a fast attack AGC circuit, and thirty sentences were modified by a slow attack AGC. The subjects marked one of …

Optimization Of Single- And Double-Flash Cycles And Space Heating Systems In Geothermal Engineering, Talal Hussein Hassoun

Dissertations and Theses

Two different problems of optimization in the utilization of geothermal energy are presented: First, the thermodynamic optimization for a geothermal power plant using a single- or double-flash process is considered; in this analysis, the optimum flash temperature giving the maximum power output is determined. Second, an economic optimization for space heating systems using geothermal energy is developed to obtain operating conditions for which the total (capital and operating) cost is a minimum.

Both graphical and analytical methods are used in the thermodynamic optimization to determine the optimum flash temperature. The graphical method is based on thermodynamic data provided by an …

The Recognition, Investigation, Interpretation, And Treatment Of Landslides In The Pacific Northwest, Harry Ludowise

Dissertations and Theses

Certain features unique to the Pacific Northwest influence landsliding in this region. Weakly consolidated sediments, dense vegetation and seasonally concentrated rainfall all contribute to the distinctive conditions that are encountered here.

This study gathers together information applying to the recognition and correction of Pacific Northwest landslides. Treatment practices common to this region are discussed.

A large slide located about 30 miles east of Portland, Oregon along the Clackamas River is used as an example. Exploration, instrumentation, analysis and corrective measures are illustrated.

Occupational Prestige Among Chinese In The San Francisco Area, Linda Fong

Dissertations and Theses

The aim of our study is to understand Chinese attitudes towards occupational prestige in order to be able to counsel families and youth in career goals, and to maximize potentials and enhance life chances. Our purpose is.to arrive first at an occupational ranking or rating since there is none to be found in the literature/on which more specific studies could later be compared. Another purpose is to see whether there I were major differences between traditional and modern Chinese, and find what traits were associated with differences in attitudes and expectations, as further indices of appropriate approaches to social services.

Air Breakdown In A Radial-Mode Focusing Element, Lee W. Casperson, Mohammad Shabbir Shekhani

Electrical and Computer Engineering Faculty Publications and Presentations

A new radial focusing device is described that condenses an incident laser beam to an extremely intense and uniformly illuminated focal spot. The focal region is useful for many applications. When used with a 10.6-µm CO₂ TEA laser source, a disk-shaped air-breakdown spark results, and the properties of this spark have been investigated.
