The Value Of Color Systems In Education, Shirley Jo Brehm

Dissertations and Theses

Color is with us everywhere, all the time. It is an integral part of our existence. Sensitivity to color and awareness of color's physical and psychological qualities is undeveloped in the normal, average human being. What can be done about this? Where can it be done? The answers to these two questions form the basis for this thesis. Color awareness as part of visual education and environmental sensitivity can be taught and should be taught in every educational institution. The key to BUCcessful instruction is informed, knowledgeable, color sensitive teachers and the exposure of students to workable color systems. Color …

Water Quality Within East Portland Terraces, Fouad Mohamed Tawfik

Dissertations and Theses

Groundwater from thirty-three wells which are randomly distributed within 42 square miles of the residential, agricultural and industrial area of East Portland Terraces have been analyzed. The area is moderately wet with an annual precipitation of about 37 inches. Residual and transported sediments from different sources, dominantly volcanic, comprise the subsurface lithology. The sedimentary units that were deposited by means of rivers and lakes have filled an original structural and erosional valley in the area. This relatively unconsolidated valley filling is about 900 feet of predominantly lenticular, stratified and cross-bedded lenses of clay, silt, sand, gravel, cobbles and boulders.

Heat Transfer Across Carbon - Liquid Helium I Interface, Constantine Antonopoulos

Dissertations and Theses

Carbon samples were electrically heated while immersed in liquid helium I. Their temperature rise was observed on an oscilloscope as a function of the time after the onset of the electric current. There was no indication of the temperature overshoot previously reported for the case of bismuth in liquid helium.

Reasons are presented for the difference in behavior of carbon and bismuth.

An Investigation Of The Development Of The Phonemes /T/ And /K/ In The Speech Of Preschool Children, Glenn Douglas Weybright

Dissertations and Theses

Research regarding children's instrumental articulation development has provided the speech clinician with schedules of speech sound development. These developmental tables list ages when specific phonemes are mastered by normal children. Such schedules tend to give the impression that certain sounds must be developed before others can occur. Menyuk (1972) has expressed a similar point of view regarding phonemes /t/ and /k/. She has hypothesized:

1. that phoneme /t/ must develop before phoneme /k/; and
2. that sound element initial /t/ is mastered at an earlier age than initial /k/. The present investigation was designed to operationally test the validity of Menyuk's observations. …

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 …

Impact Of College Speech Classes On Listening Skills Of Students, Candice Piazza

Dissertations and Theses

The purpose of this study was to determine the impact of college speech classes upon developing improved listening skills. More specifically it sought to determine the extent to which the students who took Speech 100 or 111 have acquired listening skills.

There has been considerable theorizing concerning listening and auding with only a scattering of experimentation. According to existing data, listening would appear to be a complex human behavior that is only partially understood. There are, however definite listener functions, listening conditions and variables that affect listening. Aspects of attention are also important when considering the occurrence or unoccurrence of …

Vibration Damping Characteristics Of Typical Harpsichord Strings, Jack Lee Simmons

Dissertations and Theses

Present-day builders of harpsichords disagree as to the use of iron or carbon-steel wire in their attempt to duplicate the tonal qualities of the early 16th century instruments. The variations in tone produced by vibrating iron and steel wires may be due, at least in part, to differences in their decay characteristics. A wire was set into vibration by placing a section in a magnetic field and passing a variable-frequency alternating current through it. A condition of resonance was established by appropriately selecting frequencies, lengths, and tensions that would simultaneously satisfy the relationship: fr = n/2L(T/p)1/2. Then measurements of decay …

Curanderismo And Health Delivery Services, Jean Margaret Blaesser

Dissertations and Theses

This study explores and describes curanderismo (folk curing) and the cultural disease concepts of mollera caida, empacho, mal de ojo, and susto as researched in a rural Oregon community. Chicano cultural disease concepts and beliefs are then related to modern health delivery services, and a case is made for the need for cultural awareness, respect, and sensitivity on the part of medical personnel who deliver services. The approach of a curandera (curer) and a doctor are compared.

It is strongly stated that Chicanos' health beliefs and practices do not exist in isolation from the rest of their …

Female Alcoholism: The Relationship Of Marital Status To Personality Disorganization, Julene B. Knapp

Dissertations and Theses

Research on the female alcoholic indicates that women drink for different reasons than men. Rather than being a product of role conflict as it is in males, female alcoholism is frequently precipitated by stress, particularly marital stress. For exploratory purposes a group of women seen at a public alcoholism treatment clinic were divided into four categories: 1) Non-alcoholic wives of alcoholic men; 2) alcoholic wives of non-alcoholic men; 3) single alcoholic women; 4) alcoholic wives of alcoholic men. These groups were compared. for amount of personality disorganization, using the total number of abnormal scales on the clinical profiles of the …

The Frequency Of Retroflex /R/ Production In Elementary School Children, Vicki Barna Wood

Dissertations and Theses

In articulation treatment and diagnosis, it is essential to possess a thorough knowledge of what is "normal" as well as what is "defective" articulation. The /r/ phoneme is one of the most frequently occurring and most commonly defective sounds. There are two different tongue positions for the /r/ phoneme described in the literature (retroflex and central hump), with many assumptions about which tongue position is "normal" or "most common." None of these assumptions, however, are based on empirical data.

The purpose of this study was to provide some normative data regarding which of the two tongue positions is most common …

An Investigation Of The Influence Of Dialectal Interferences On The Nsst Scores Obtained By Portland Black Children, Margaret Jeanne Callahan

Dissertations and Theses

The primary purpose of this study was to determine if dialectal interference as described by Walter Wolfram was exhibited by black children in Portland, Oregon when given the NSST by Laura Lee. This author was concerned with syntactical interferences on the expressive portion of this test.

A secondary purpose of this investigation was to provide suggested norms for differentiating children with language deficits from children with language differences.

Seventy black children with normal speech and language were selected from two public schools, a Head Start Center and a day care center. These children were between the ages of 3-0 to …

Colored Light: A Brief Study Of Stained Glass Windows, Including A Self-Guided Tour Of Stained Glass In West Portland, L. Jean Connors

The Politics Of Education -- An Analysis Of Selected Cases And Controversies In American Education, Lawrence Robert Stoffel

Dissertations and Theses

This study compiles a series of cases and controversies in American education, from the popularization of public education in the mid-1800's to the present, and then reviews them to determine scholarly political aspects, common themes, and trends. It then applies the identified themes to a model of “the school as a responsive political system” fashioned after David Easton's "Dynamic Response Model of a Political System” to demonstrate the operative nature of the themes.

The paper reviews the plight of Negro education in Alabama after the Civil War until 1901. It discusses accommodation in the realm of education as the United …

An Exploratory Study Of Depression In Adolescents Placed In Residential Treatment Centers, Shirley D. Hale, Kermit C. Jeffrey, Gerald J. Moneke

Dissertations and Theses

Concerned that depression might be a common malady among youth who are placed in treatment centers for delinquents, we undertook an exploratory study to determine the validity of this premise. The authors of this study have all worked with youth who, for various reasons, have been placed in residential treatment centers. The authors have observed that symptoms of depression seem to be more prevalent in these youth than in non-institutionalized adolescents, and that these symptoms are often perceived as individual pathology rather than emotional responses common to institutionalized youth. We thus began questioning if these were common emotional responses, and …

Age, Intelligence, And Socioeconomic Status Variance In Preposition Acquisition By Children, Georgie Hustead

Dissertations and Theses

Numerous linguistic studies have been done to substantiate the importance of prepositions in the English language. However, no normative studies have been done on the acquisition of expressing prepositions.

The purpose of this investigation was to determine if there were demonstrable trends which would indicate a need for normative data on the acquisition of twenty-six prepositions tested on the Expressive Preposition Test (EPT). The study set out to determine at what age levels a given percentage of the prepositions were expressively acquired and if the socioeconomic status (SES) of the child’s family would be a determiner as to the age …

Interaction Patterns In The Campground, Dennis Lee Rockwood

Dissertations and Theses

The purpose of this project was to examine interaction patterns in various campground settings and to elaborate on camping literature which has suggested that the campground is a social event with high rates of interaction. In exploring this phenomenon, this report utilized observational techniques to document the temporal, spatial, familiarity, numerical, and behavioral dimensions of the observed interactions.

The data suggested that young adults and middle-aged persons were observed to be involved in, and initiated the highest proportions of, interactions. In general, males displayed far greater proportions of initiations than females. The highly developed campground exhibited higher proportions and rates …

The Effectiveness Of Induced Location Of Manufacturing Industry As A Means Of Fostering Sustained Economic Growth In Less Developed Regions Of Oregon, Leland F. Smith

Dissertations and Theses

The subject of this thesis was chosen from both a professional and an academic interest in the economic development of Oregon. Prompted by proposals made to the Oregon Legislature to initiate various forms of industrial subsidy programs to disperse economic growth and population away from congested areas, this research effort seeks to provide an evaluative analysis of the effectiveness of subsidy techniques in influencing industrial location and stimulating a sustained growth process in less developed areas.

Research was undertaken in two primary subjects: 1) theory of regional economic development and the effects of subsidies on the growth process; and 2) …

Knowledge And Use Of Social Services In Gervais, Oregon, Elizabeth Lewis, Abby Maier, Lajuana J. Morton

Dissertations and Theses

During first year field placement, we worked with a number of rural families, most of them Mexican-American. It seemed to us that rural families in general and Mexican-Americans in particular were not being very well served by social service agencies. We questioned whether this might be due to a lack of Mexican-American perspective in traditional services or perhaps a lack of Mexican-American manpower or at least Spanish-speaking manpower.

This study, then, developed out of a general area of interest that can be stated as three questions: (1) Do rural people (especially Mexican-Americans) feel there is a need for various social …

Masking Patterns Of High Frequency Pure Tones, Judith Eide Widen

Dissertations and Theses

Previous investigations of masking have established that the action of the masking tone spreads upward in frequency, creating significantly more masking (threshold shift) above the masker frequency than below. It was the purpose of this study to investigate the masking pattern produced by high frequency pure tones, heretofore uninvestigated.

Masking patterns were obtained for nine normal hearing young adults utilizing the method of adjustment. The masking produced by an 11000 Hz pure tone of 40 dB sensation level was measured at three frequencies above and three frequencies below the masker frequency. Analysis of the data revealed a downward spread of …

State Response To The Civil Right Issue, 1883-1885, Robert Lionel Rowe

Dissertations and Theses

The purpose of this study is to reexamine the assumption in American historiography that the United States Supreme Court's monumental decision in the Civil Rights Cases striking down the 1875 Civil Rights Act represented the end of the Nineteenth Century commitment to "equality under the law" and the civil rights issue. The evidence shows that while the decision had overwhelming support, much of this was support for the Court’s view that such legislation was not within the scope of Federal power.

Eleven states responded to the Supreme Court’s decision by rapidly enacting civil rights legislation. The research centered on gathering …

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 …
