Auditory And Visual Sensory Stores: A Recognition Task, James Barr Richardson

Dissertations and Theses

A probe-stimulus recognition technique was used to test hypothesized differences in visual and auditory sensory memory storage. Lists of alphabetical letters were presented visually or auditorially, each followed by a visual or auditory probe. Performance on the auditory lists was predicted to be better than on the visual lists. Moreover, auditory lists followed by a visual probe (AV) were expected to show a decrement in performance in comparison to auditory list-auditory probe tasks (AA). Visual lists followed by an auditory probe (VA) were likewise expected to result in a decrement in performance in comparison to visual list-visual probe tasks (VV). …

The Pregnancy Counseling Group; An Analysis Of A Sample Of Women Served By Planned Parenthood Association, Portland, Oregon, Marcia Jean Lapham

About a year later, in October of 1970, the Planned Parenthood Association in Portland began to offer pregnancy testing and counseling as part of their services. This is a new and separate program which is designed to help women find out if they are pregnant as early as possible (at low or no fee) and provide counseling on the problems connected with unwanted pregnancy. This study is based on a sample of women seeking pregnancy counseling at Planned Parenthood in Portland in the calendar year 1971. During that year about 1,230 …

A Study Of The Characteristics Of Runaways And Their Families In Two Social Agencies, Susan G. Greer, Sarah J. Hertlein, Stephen C. Regner

Dissertations and Theses

Because of the relative uniqueness of the runaway experience as it now exists, minimal current research information is available. It was our feeling that knowledge about runaways, their families, and the social agencies which serve them is essential if significant prevention and treatment for the problem were to be implemented by the community. The purpose and scope of this exploratory research was essentially two-fold; to contribute descriptive information about runaway youth and their families to the community, and to evaluate the current populations of two agencies which service them. An underlying goal throughout the research was to utilize the data …

An Analysis Of Change In Girls Released From Villa Saint Rose, H. Marie Ades

Dissertations and Theses

When juveniles are defined by society as delinquent they are frequently institutionalized. These institutions are referred to as reform schools, correctional institutions or schools, residential care facilities, treatment centers, or variations of the above. They are state sponsored or privately sponsored. Whatever name is on the sign by the front door, each institution is in the business of "people changing."

The excellence of an inanimate product can be measured, weighed, checked, and reproduced; but an altered person is more difficult to measure. If one is in the business of people-changing, it seems important to see if one is in fact …

Diagnostic Congruence: A Study On Presentation Of Clinical Information To Parents And Recall, Miriam Rae Maier

Dissertations and Theses

The present study was an investigation of recall following presentation of diagnostic information. The setting was the Crippled Children's Division of the University of Oregon Medical School.

The purpose of the study was to test the hypothesis that one session conferencing imparting diagnostic information to parents of handicapped children reduces recall. Additionally, it was hypothesized that multi-discipline conferencing is related to greater diagnostic recall than single discipline conferencing. The sample was made up of 20 parent units whose children were evaluated at the Crippled Children's Division for suspected Cerebral Palsy and/or Mental Retardation. There were ten families from the Cerebral …

A Functional Interpretation Of Pottery From Batan Island, Philippines, Joanne M. Laetsch

Dissertations and Theses

This thesis is a report on a pottery analysis which was carried out in the laboratory of the Department of Anthropology at Portland State University. The earthenware materials involved were collected from three surface sites on Batan Island, Philippines, during the summer of 1969.

The interpretation of these potteries was based upon the direct-historical approach to archaeological research. The use of this method was proposed after a cursory examination of the earthenwares revealed certain general similarities between the archaeological potteries and the ethnographically-known wares produced in the area at the present time. One of the sites was a known habitation, …

The Impact Of Coordination By A Child Abuse Committee On Community Services To Battered Children, Grace Jackson Anders, Rebekah M. Burton

Coping Patterns Of Those Denied Public Assistance -1970, Robert A. Turcotte, Anita L. Wahl

Dissertations and Theses

The purpose of this project was to explore the coping patterns of people denied public assistance. The primary focus was on resources available and used by those denied to assist them in the situation that led them to apply for public assistance in the first place.

A review of the literature revealed that very little is known concerning those denied public assistance. This project is one of the first to study the problem of how those denied manage after denial.

The data for this project was gathered by the use of an interview schedule administered in personal interviews with those …

Illusion Und Verfremdung: Begriff, Form Und Wirkung, Bezogen Auf Bertolt Brecht: "Der Gute Mensch Von Sezuan", Robert E. Folk

Dissertations and Theses

Perhaps Bertolt Brecht's most obvious intention in connection with the theater was to help change the economic conditions, under which the people in a capitalistic society live. But, according to him, this could only be possible if the people were to develop a critical attitude and awareness of the contradictions that exist in such a society, in which "exploiters exploit the exploited", to put it in Brecht's straightforward terminology. It was his goal in the theater to help the spectator achieve this critical attitude. However, it was his opinion that this could only be done by rejecting the traditional theater …

The Life Cycle Of Lissorchis Heterorchis, Macy And Krygier (1969), Brendan P. H. Onyejekwe

Dissertations and Theses

Many Flumenicola virens (Lea) collected from Crystal Springs Creek and Tualatin River, Portland, Oregon, were found to shed large numbers of a species of microcercous cercariae containing refractile granules. They resembled the cercariae of Triganodistomum mutabile (=Lissorchis mutabile Cort, 1918 as described by Wallace (1939), and subsequent experiments proved that they were the larval stages of what was described by Macy and Krygier (1969), as Lissorchis heterorchis. Encystment of these cercariae was induced experimentally in uninfected adult brown planarians collected partly from Crystal Springs Creek and partly from Carolina Biological Research Station in Gladstone, Portland, Oregon. Adult flukes …

Application Of Numerical Analysis To Root Locus Design Of Feedback Control Systems, Steve William Justice

Dissertations and Theses

Many practical problems in the field of engineering become so complex that they may be effectively solved only with the aid of a computer. An effective solution depends on the use of an efficient algorithm. Plotting root locus diagrams is such a problem. This thesis presents such an algorithm.

Root locus design of feedback control systems is a very powerful tool. Stability of systems under the influence of variables can be easily determined from the root locus diagram. For even moderately complex systems of the type found in practical applications, determination of the locus is extremely difficult if accuracy is …

Comparison Of Amounts Of Verbal Response Elicited By A Speech Pathologist And A Mother In The Clinic, Sherry Lee Nelson

Dissertations and Theses

One of the primary responsibilities of a speech pathologist is the assessment of a child's language. Many studies have been done in the area of language development. The results of these studies have varied causing concern among researchers over the validity of the data gathered. Many factors that could affect the results of previous research have been investigated. Until recently, however, there has been relatively little research about the effects of examiner differences on the results of language assessments.

Research in the area of examiner differences has resulted in the discovery of factors which could affect the results of language …

Catechol Effected Dissolution Of Silicate Minerals, James Maurice Kelley

Dissertations and Theses

The chemical properties of guanidinium tris(catecholato)siliconate, [(H₂N)₂C=NH₂]₂[Si(C₆H₄O₂)₃]·XH₂O (0 < X < 1), precipitated from an ammoniacal solution of silica and catechol by adding guanidinium hydrochloride, (H₂N)₂C=NH·HC1, were studied, and infrared, nmr, x-ray powder diffraction, and analytical data were gathered.

This same compound was, upon addition of' (H₂N)₂C=NH·HC1, isolated from 0.25, M aqueous catechol solutions buffered at pH 10 and containing the silicate minerals albite, andradite, muscovite, pyrophyllite, talc, and wollastonite, and also from unbuffered catechol solutions containing wollastonite and andradite.

It is concluded from this work that the formation of an anionic catechol-silicon complex, Si(C₆H₄O₂)₃²⁻, is largely responsible for the dissolution of the minerals mentioned above. From this conclusion, it is proposed that naturally occurring members of the class of organic compounds to which catechol belongs, the aromatic v̲i̲̲c̲-diols, may play …

The Effect Of Glucose On The Food Intake Of Goldthioglucose Injected Mice, Janet Lahti

Dissertations and Theses

Jean Mayer has postulated the presence of glucoreceptors located primarily in the ventromedial hypothalamic nuclei of the brain which are activated by glucose in the measure that they utilize it. According to Mayer, hunger occurs when glucose is not available for metabolic purposes and satiation supervenes when glucose is made available. Control of this mechanism rests with the glucoreceptors. These receptors are believed to be destroyed when an injection of the compound goldthioglucose is given to mice. These animals subsequently become obese and are found to have gold deposits and lesions in the ventromedial area and also in other parts …

W. S. U'Ren And The Fight For Government Reform And The Single Tax: 1908-1912, David Elvin Lindstrom

Dissertations and Theses

In the study of Oregon politics, the importance of developments in the early twentieth century have been largely overlooked by popular historians. As a result, many have lost the perspective of the sweeping reforms that reformers presented to Oregon's electorate. Another complicating factor is that voters dealing with the issues during the period had such disparaging attitudes towards some of the reforms, that no thought was given to preserving their memory for future generations. In addition, the personal papers of W. S. U'Ren, Oregon's leading reformer, are not available. This makes perspective even more difficult. Therefore, the research problem is …
