The Effect Of Human Activity On The Middle Course Of The Tualatin River, Oregon, Lolita M. Carter
The Effect Of Human Activity On The Middle Course Of The Tualatin River, Oregon, Lolita M. Carter
Dissertations and Theses
A diurnal study of biological, chemical, and physical parameters was made on the middle course of the, Tualatin River, which drains a 1840 km2 (711 mi2) basin adjacent to metropolitan Portland, Oregon. This portion of the river lies along land in transition of use from rural agriculture to highly urbanized development.
There is no nutrient loading of the river from farming practices because there was no return of water from summer, sprinkler irrigation of commercial crops. However, irrigation significantly reduces the volume of water in the river in the summers.
Effluents from sewage treatment plants flowing into …
A Comparative Study Of The Reponses By Varying Socioeconomic Groups On General Knowledge And Categorization Tasks, Margo I. Keller
A Comparative Study Of The Reponses By Varying Socioeconomic Groups On General Knowledge And Categorization Tasks, Margo I. Keller
Dissertations and Theses
This study sought to determine if there are any "cultural" or economic level patterns of behavior in responding to tasks involving categorizing pictures and recalling general knowledge. The Daberon School Headiness Device (1972), which contains subtests for general knowledge and categorization, was used to assess four groups of children: 1) lower-SES white, 2) lower-SES black, 3) middle-SES white, and 4) middle-SES black. This study involved thirty black and thirty white children between the ages of five years and five years, eleven months. All subjects were screened to determine race, age, auditory acuity, speech intelligibility, subject cooperation, and socioeconomic status (SES). …
Attendance At Out-Patient Clinics As A Function Of Risk Taking For Alcoholics, John Ketcham Fryer
Attendance At Out-Patient Clinics As A Function Of Risk Taking For Alcoholics, John Ketcham Fryer
Dissertations and Theses
Many-psychotherapists feel that the capacity to risk is a necessary ingredient for change. Whether that change occur in a person seen in a professional context or in a person who views new behavior as being more rewarding, risk and change go hand in hand. Coleman (1972) described this relationship in the following way:
Life often poses problems in which the pursuit of increased satisfactions involves giving up present hard-won security and taking new risks. For the neurotic, this is likely to prove an especially anxiety-arousing conflictful situation [p. 226].
Why should this be true? It seems that one of the …
Implications Of American Missionary Presence In 19th And 20th Century Iran, Linda Colleen Karimi
Implications Of American Missionary Presence In 19th And 20th Century Iran, Linda Colleen Karimi
Dissertations and Theses
American missionaries to Iran exerted little influence in the area of religion, rather their impact was in education and medicine. Two decisive factors involved in their success were the awakening of Iran to the advances of Western technology and the limited scope of indigenous opportunities in the fields of learning and medicine. Their work in Iran was, however, hampered by opposition from those elements wishing to retain the status quo. In spite of such reactions, they were able to maintain their positions in Iran for approximately one hundred years. It was the advent of the Pahlavi dynasty which initially limited …

A Descriptive Study Of Previously Institutionalized Educable Mentally Retarded Adults Residing In Multnomah County, Oregon, Susan J. Kiley, Jeffrey D. Sher, Richard C. Sunshine
A Descriptive Study Of Previously Institutionalized Educable Mentally Retarded Adults Residing In Multnomah County, Oregon, Susan J. Kiley, Jeffrey D. Sher, Richard C. Sunshine
Dissertations and Theses
This is a study of mild and borderline mentally retarded adults living in Multnomah County, Oregon, who at one time in their lives were patients at Fairview Training School. The concept of "normalization" is merging with the political necessity of "advocacy" to create a different role for the traditionally silent and previously institutionalized retarded citizen, along with new roles for the professional worker with the retarded. Mentally retarded citizens have only recently begun to speak out for themselves; even less frequent it seems, has any concerted listening on the part of the public or professional community which deals day to …

Analysis Of The Port Of Portland Facility Hinterlands, Timothy D. Wilson
Analysis Of The Port Of Portland Facility Hinterlands, Timothy D. Wilson
Dissertations and Theses
Most of the United States port authorities delineate their hinterland by the use of freight rate schedules used by inland carriers. The hinterland is defined as that region having favorable rates to and from a port. The use of freight rate schedules can be applied to a) individual commodities or to b) all the commodities moving through a port. The freight rate method is built on the "rational man" concept. That is, a situation is assumed where there is "perfect knowledge" and a desire to minimize transportation costs. This assumption does not always coincide with reality.
This paper classifies commodities …
A Comparison Of Responses Between Two Different Socioeconomic Groups On The Boehm Test Of Basic Concepts, Teri Jones Geist
A Comparison Of Responses Between Two Different Socioeconomic Groups On The Boehm Test Of Basic Concepts, Teri Jones Geist
Dissertations and Theses
The primary purpose of the investigation was to compare the responses of white, lower-class kindergartners and first graders with white, middle-class kindergartners and first graders on the Boehm Test of Basic Concepts (BTBC) in order to determine if a statistically significant difference existed between socioeconomic level and the number of concepts correctly identified on the BTBC. A secondary purpose was to determine is a significant relationship existed between concept development as measure by the BTBC and intelligence from an assessment of receptive vocabulary by using the Peabody Picture Vocabulary Test (PPVT).
One hundred white, lower …
The Relationship Between Self-Concept And Responses Of Others During A Marital Crisis, Kathryn Ann Farr
The Relationship Between Self-Concept And Responses Of Others During A Marital Crisis, Kathryn Ann Farr
Dissertations and Theses
Symbolic interaction theory indicates that an individual's self-concept is related to the way in which the individual perceives others as responding to him/her. Although this theory is widely accepted in social psychology, it has been given little empirical attention. In this study a typological model was developed in an empirical examination of the relationship between self-concept and responses of others during marital crisis. Self-concept was defined as the organization of qualities (roles, social-psychological feelings) that an individual assigns to himself/herself. Kind of qualities were described, and social-psychological feelings about self were examined on a positive to negative continuum. Responses of …
The Relationship Between The Housing Environment And The Child's Behavior: Strategies For Adapting To Multi-Family Housing, Anthony J. Filipovitch
The Relationship Between The Housing Environment And The Child's Behavior: Strategies For Adapting To Multi-Family Housing, Anthony J. Filipovitch
Dissertations and Theses
This study is an inquiry into some of the effects of the housing environment on the behavior of children. The city can be seen as a structure which facilitates communication and interaction because of the large number of intersecting individual pathways which the city represents. Young children, however, have little experience of this city: for the most part, their microcosm extends only a few blocks from home. Cities are a function of density and large numbers of people, and these two characteristics are also descriptive of multi-family structures. In the child's microcosm, multi-family dwellings could be considered as the type …
Drop-Out Study, Chemawa Indian School, Terry Farrow, Gordon Oats
Drop-Out Study, Chemawa Indian School, Terry Farrow, Gordon Oats
Dissertations and Theses
Repeated inquiries and statements are made about the number of American Indian students who drop out or are pushed out of school. The Waxes noted that while drop-out rates are difficult to calculate because of a shifting population and absence of centralized, accurate records, current figures indicate that about one-half of those who enter the primary grades drop out before entering high school. Furthermore, only about a third of those entering school actually graduate. A study of Pima and Papago schools revealed much the same trends. Seven percent of the children ages six to eighteen are not enrolled in any …
A Study To Differentiate Between Runaways And Non-Runaways Among Juveniles Reported Missing, Neil E. Crannell, Patricia A. Hoffman
A Study To Differentiate Between Runaways And Non-Runaways Among Juveniles Reported Missing, Neil E. Crannell, Patricia A. Hoffman
Dissertations and Theses
It is the purpose of this research project to develop a profile of predictive variables that would be helpful in distinguishing a missing juvenile report of a runaway from that of a missing youth who may have met with "foul play" and who does not fit the pattern of the runaway youth. The usefulness of such a tested set of predictive variables would be in designing a report form to be used by the peace officer who takes the initial report enabling him to immediately identify the situation as one of a runaway indicating one type of follow-up as opposed …

Indian Alcoholism On Reservations, Cleora E. Jackson
Indian Alcoholism On Reservations, Cleora E. Jackson
Dissertations and Theses
The purpose of this practicum is to describe the destructive use of alcohol among Southeastern Idaho Indians. This practicum is based on John and Irma Honigmann's (1) theory of "loss of stake." It is John and Irma Honigmann's contention that whatever may be the social functions of drinking, and whatever the personal reasons, having a stake in society tends to induce people to conform to the norms of society with regard to drinking behavior. The three case histories in this practicum will illustrate more of what is meant by the theory of stake in society.
Problem Oriented Case Planning, Jack A. Morgan
Problem Oriented Case Planning, Jack A. Morgan
Dissertations and Theses
This practicum report discusses the adaptability of problem oriented case planning to casework which is practiced in the Northeast Multnomah County District Office of the Children’s Services Division. Problem oriented case planning is an approach designed to make casework more explicit by specifying the target problem(s), goals(s), tasks and an evaluation scheme which are agreed to and stated in a written contract developed by the participants. Such explicitness is essential to permit agency collection of useful information about its casework and casework programs needed to respond to today’s accountability demands, i.e., demonstration that the agency operates at a reasonable level …

The Use And Evaluation Of Gestalt Techniques In A Program For The Parents Of Handicapped Children, Richard Roy Hammond, Robert E. Phillips
Dissertations and Theses
The goal of this paper will be to further explore the use of Gestalt therapy in the Parent-Education Program and to find a way in which its effectiveness in freeing parents of emotional barriers to growth can be evaluated. Our specific objectives will, therefore be to (1) review the literature and present our own assumptions on parental responses to having a handicapped child, (2) explore the basis of Gestalt therapy and relate it to the needs of parents who have handicapped children. (3) describe the setting in which the Parent-Education Program and its Gestalt component takes place, and (4) suggest …
An Exploration Of The Feelings And Attitudes Of Women Separated From Their Children Due To Incarceration, Dorothy Lundberg, Ann Sheekley, Therese Voelker
An Exploration Of The Feelings And Attitudes Of Women Separated From Their Children Due To Incarceration, Dorothy Lundberg, Ann Sheekley, Therese Voelker
Dissertations and Theses
Although significant research has shed light on what happens to children when they are removed from their parents, few studies have explored the effects on parents undergoing separation from their children. Discussions tend to be confined to separate dimensions exploring child's needs on one side and parental obligations on the other. Much of the planning and prolonged care provided for children in placement reflects a traditional child-centered focus. This has led to a lack of attention to parental needs, and a gross ignorance about their lives, feelings and aspirations.
When women are involuntarily separated from their children through incarceration, a …
Structure Vs. Meaning In Subliminal Perception, Margaret Anne Callan Hoisington
Structure Vs. Meaning In Subliminal Perception, Margaret Anne Callan Hoisington
Dissertations and Theses
Subliminal perception is defined as a process whereby a subject reports no awareness of a visual stimulus, and yet his/her verbal behavior, subjectively experienced as “guesses”, is influenced by the stimulation. Various studies have found evidence for and against subliminal perception using discrimination tasks and subjective judgments. Explanations of subliminal perception include the partial cue hypothesis, the theory of perception of structural differences, and the theory that responses to subliminal stimuli are of a semantic nature.
This study was conducted to determine whether subliminal perception involves a discrimination of structural characteristics or a discrimination of the semantic quality of words …
The Morphology Of The Eye Of The Purple Shore Crab, Hemigrapsus Nudus, Sharon E. Heisel
The Morphology Of The Eye Of The Purple Shore Crab, Hemigrapsus Nudus, Sharon E. Heisel
Dissertations and Theses
A structural analysis of the compound eye of Hemigrapsus nudus expands the basis of functional analysis of decapod Crustacean eyes. Contradictory evidence for disintegration of rhabdomeric microvilli in the absence of light prompted observation of H. nudus eyes after 146 days in darkness.
Eyes were fixed with formalin and glutaraldehyde and post fixed with osmium tetroxide for electron and light microscopy. Light- dark-adapted eyes were also observed with hot water fixation and paraffin embedment.
The eye of H. nudus is typical of decapod Crustacean compound eyes. Corneagenous cells underlie the transparent cuticle cone cells secrete the composite crystalline cone which …
Shaping Of Marital Interaction: A Clinical-Research Approach, Cynthia Luders Clay
Shaping Of Marital Interaction: A Clinical-Research Approach, Cynthia Luders Clay
Dissertations and Theses
In the last ten years, a number of behavioral approaches to marital therapy have been developed and applied to married couples. Intervention techniques have included selective reinforcement, extinction, modeling, aversive consequences, and contingency contracting. The present study investigated the use of the bug-in-the-ear (BITE) instrument as an aid in shaping marital interaction. The BITE has been applied in several child behavior modification programs, but no applications in marital therapy have been reported.
The use of the BITE has been demonstrated and is considered clinically feasible. Since the N of this study was small and since the raters evaluating progress were …
An Analysis Of The Effects Of Individual Counseling And Group Process Techniques Upon The Behavior Of Children In A Juvenile Detention Facility, Robert Arthur Struble
An Analysis Of The Effects Of Individual Counseling And Group Process Techniques Upon The Behavior Of Children In A Juvenile Detention Facility, Robert Arthur Struble
Dissertations and Theses
A three month project was designed to study the effects of individual counseling combined with group process techniques upon the behavior of children in a short term detentional facility. The length of stay was also a primary variable. In the study of this behavior.
The behavior of 282 males, 14 to 17 years of age, whom had been to the juvenile detention facility in Portland, Oregon, was analyzed via three separate instruments. The Behavior Activity Inventory was utilized to obtain daily observations concerning four separate areas of interest. An attitudinal rating scale was devised to obtain the staff’s assessment as …
Recovery From Stuttering In A Sample Of Elementary School Children, Carol Deno Kimball
Recovery From Stuttering In A Sample Of Elementary School Children, Carol Deno Kimball
Dissertations and Theses
Several studies have been undertaken to determine the incidence of recovery from stuttering; however, the results of these investigations are not reliable due to methodological limitations. For the most part, ex-post-facto recall judgements on the parts of adults or parents of young children were relied upon in gathering data for the research. It would appear that a requisite factor in determining incidence of recovery from stuttering should be the use of a formal instrument which would quantify the auditory and visual aspects of speaking behavior to determine the presence or absence of stuttering.
The primary purpose of this study was …
A Descriptive Study Regarding Perceptions Of Sex Roles In Cooperative Households, Emily Fultz, Billie Huntwork
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 …
Toward A Theory Of Child Abuse: A Review Of The Literature, Marc F. Maden
Toward A Theory Of Child Abuse: A Review Of The Literature, Marc F. Maden
Dissertations and Theses
Currently, there exists no conclusive etiology of child abuse although there are two major and contrasting theories which attempt to impart a systematic interpretation to the data. The purpose of this study was to determine what are the significant factors in child abuse and to what extent the respective theories render a coherent and comprehensive explanation of these factors. This study aggregated the data on the demographic, social, economic, and psychological features of the child abuse victim and perpetrator. Each study was analyzed according to a methodology of review which considered the problems involved in eliciting meaningful data from a …
