Measurement Of Ambiguity Tolerance (Mat-50): Further Construct Validation, Burl Mostul

Dissertations and Theses

An historical introduction is made tying authoritarianism with ambiguity tolerance. Ambiguity tolerance is a personality variable in its own right, often associated with authoritarianism yet remaining separate from it.

Ambiguity intolerance is defined as the tendency to perceive and interpret information that is marked by vague, fragmented, incomplete, inconsistent, contradictory, or unclear meaning as actual or potential sources of psychological threat. Ambiguity tolerance is defined as the tendency to perceive ambiguous situations as challenging and desirable.

Efforts to measure ambiguity tolerance have met with varied success, however, it was not until Norton (197S) developed the Measurement of Ambiguity Tolerance (MAT-50) …

A Comparison Of The Clinician-Client Interactions In Urban Language And Stuttering Clinics, Teresa M. Carnese

Dissertations and Theses

The purpose of this clinical research project was to use an interaction analysis system to compare the behaviors of clinicians and their clients with two types of communicative disorders and to determine how the clinicians utilized their clinical time. More specifically, this study employed the Conover Analysis System (Conover, 1974) and compared the client-clinician behaviors in the Portland State University Urban Language Clinic and Stuttering Clinic. The data which were gathered provided a baseline of the client-clinician behaviors in the two clinical settings.

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 …

Bird Use Of Revetted Riverbanks In The Willamette Valley, Clifford Brian Perry

Dissertations and Theses

Over 115 miles of rock revetments that serve to protect river banks have been constructed in the Willamette Basin. In this study the spring and summer bird use of Willamette Basin revetments is examined. Revetments that had not been recently cleared of most woody vegetation and blackberries were found to have significantly greater total and breeding bird use than cleared revetments. Possible factors affecting bird use, such as vegetation on revetments and vegetation adjacent to revetments are examined using linear regression analysis. The results of this study are compared with results of previous work in riparian forests along the Columbia …

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, …

In addition, four associations (paleo-communities) of benthic mega invertebrates, the Gervillia, Protocardia, Isocyprina …

Landscape Painting In The Secondary Classroom, Margaret Shirley

Dissertations and Theses

This thesis attempts to demonstrate an approach to secondary art education which will emphasize the student's own experience as the basis of his art work. Furthermore, the students' learning activities are given a broader context by the inclusion of material from the history of art within the framework of the studio course. Such an integrated approach can give meaningful insight to the adolescent as he deals with experience in a visual form.

This orientation to art education has evolved through the writer's own teaching experience and from reading the works of art educators. In preparation for the thesis, I researched …

Educational, Sociocultural, And Phonological Obstacles For The Japanese Learner Of English, David Howard Waterbury

Dissertations and Theses

Every Japanese high school student studies English for at least six years. However, the results of this study, especially in speaking, are poor. In the present study, educational, sociocultural, and linguistic obstacles to learning for the Japanese student are considered.

An educational system oriented toward passing college and university entrance examinations has distorted English curriculum. Furthermore, English teachers in Japan lack proficiency in the language. The teaching staffs and materials of language schools are poorly regulated.

Concern with relative status, group identification, and loss of face acts as a deterrent to learning. For many learners the wrong type of motivation …

These criteria relate to destination choice behavior in the context of recreation travel, and analytical structures of travel demand, in addition to the criterion of model performance. The thrust of this research is to define and evaluate a destination choice function with respect to recreational travel.

Distribution And Behavior Study Of Diurnal Tree Squirrels In Portland, Oregon, With Emphasis On The Western Gray Squirrel (Sciurus Griseus Griseus Ord) And The Western Fox Squirrel (S. Niger Rufiventer E. Geoffroy St.-Hilaire), Ira Young Rice Iii

Dissertations and Theses

Populations of diurnal tree squirrels in the Portland area were located by mail surveys, personal interviews, and field inspections. Pine squirrels were found to reside in thickly wooded residential areas with dense understories and running water nearby. Western gray squirrels occupied habitats in relatively quiet residential neighborhoods, in areas well supplied with mast crops. Western fox squirrels were found to coexist with gray squirrels in their preferred habitat, and also to thrive in park settings with few mast trees and high activity and noise levels. In areas occupied by both fox and gray squirrels, dominant-subordinate relationships were noted. Each species …

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 …

International Law, German Submarines And American Policy, Janet Marilyn Manson

Dissertations and Theses

This thesis is a survey of the available material on the submarine issue during 1914-1917 as a factor in German-American relations which contributed to the American declaration of war in April 1917. No other scholarly work is devoted solely to the submarine issue during this period. The purpose of this thesis is to focus on the submarine as an international legal issue. German-American relations were strained during 1914-1917, because of the different interpretations of international law regarding the submarine. And this thesis was written in order to test the existing historical interpretations of the submarine issue as a focal point …

Characterization Of Trace Iron Species In Natural Water, James Robert Johnson

Dissertations and Theses

The distribution and speciation of trace metals in natural waters is only slightly, at best, understood. Interactions with organic substances can effectively distribute the metals throughout many ill-defined physical and chemical. To better comprehend the complexity of metal-organic interactions this work focused on the delineation of trace iron species present in a natural system. The separation of Fe(II) and Fe(III) was successfully accomplished using a variation of an ion exchange method involving resin-loaded filter paper. The quantitation of the various iron species was determined using linear scan voltammetry and atomic absorption. The total iron concentration, determined as the sum of …

The Mentally Retarded's Right To Meaningful Treatment: A Review Of Legal And Psychological Literature, Susan Katherine Peters

Dissertations and Theses

A review of legal provisions and practices and current psychological theory and research concerning the mentally retarded indicated inconsistencies between the law and current theory, Laws have been based on archaic models which fail to consider the heterogeneity of those classified as retarded and their potential for development and training. Retardation professionals have agreed that normalization of institutionalized mentally retarded and mainstreaming in education are preferable principles. Research comparing the effects of community living and institutionalization and effects of special and integrated classes was sparse and inconclusive; the major thrust of research has been on the 4% of all mentally …

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, …

The Berrigans At Catonsville: A Case Study In Symbolic Behavior As Rhetoric, Susan Baker

Dissertations and Theses

In May of 1968, Father Daniel Berrigan, a Jesuit priest, and his brother, Father Philip Berrigan, a Josephite priest, and seven others, entered the draft board offices in Catonsville, Maryland where they removed 378 draft files and burned them with homemade napalm.

This paper examines that event as a case study in symbolic behavior as rhetoric. In doing so, the author first seeks a definition of rhetoric, and a definition of symbolic behavior. Background material, both on the Berrigans, and on symbolic behavior as rhetoric is provided.

The major portion of the paper deals with the analysis of the event …

The Use Of Discrediting Labels In The Maintenance Of Socially Constructed Reality, Nathan Church

Dissertations and Theses

Over the past two decades an increasing number of theorists and practitioners have called for a thorough rethinking of the underlying assumptions of the concept of rrental illness and the traditional psychiatric nodes of responding to mental disorders. The work of this group of writers has come to be referred to as the "antipsychiatry" literature. The insights of this perspective center largely about a rejection of those theories and methods of treatment that are based upon the medical model. Many writers point to the use of traditional psychiatric practice as an oppressive instrument of social control. While much of this …

Choice And Success: The Evolution Of A Modern Hero, Laurence W. Ranstead

Dissertations and Theses

The phenomenon of modern fantasy is the result of a tradition that originated with romance. It is a tradition that has experienced continual redefinement and utilization over the years. This is evidenced by the rediscovery of certain characteristics of the Medieval Romance and the development of others by the Romantics, William Blake, William Wordsworth, and Samuel Taylor Coleridge. These characteristics are identifiable in the works of such later writers as Charles Dickens, William Morris, H.G. Wells, G.B. Shaw, C.S. Lewis and J.R.R. Tolkein. The concern of these succeeding authors is the same as that of the Romantics, i.e., the nature …

Role Demands Of Professional Women In Jeddah, Saudi Arabia, Soraya Wali El-Deen Assad

Dissertations and Theses

The present thesis is concerned with professional women in Jeddah, Saudia Arabia. Because of the social changes taking place in Saudi Arabia, the position of women is subject to both traditional and modernistic influences. While an increasing number of females are receiving higher education and expanding their aspirations , the traditional cultural values dealing with woman's role in the family are still an important consideration.

The thesis is based on the theoretical perspective that the individual role system is over-demanding. Fulfilling role demands causes difficulty or "strain"; if a person conforms fully in one direction, fulfillment will be difficult in …

The Union Bimetallic Party Of Oregon, 1896-1898, Ludger Mogge

Dissertations and Theses

On March 23 - 26, 1898, Populists, Democrats, and Silver Republicans of Oregon held their state conventions in Portland and agreed upon a common platform and a common state ticket for the elections of June 6, 1898. None of the available works on Oregon history explains that this fusion was the culmination of a two-year effort to unite the reform forces the state. This thesis tries to fill the gap. Because of the lack of secondary works on the subject, the thesis is based mainly on two sources: newspapers on microfilm, especially The Oregonian; and the unpublished correspondence of party …

The Effects Of A Political Boundary Running Through A Metropolitan Area: A Case Study Of The Establishment And Functioning Of The Jantzen Beach Shopping Center, Rose Romaine Reed

Dissertations and Theses

Jantzen Beach Shopping Center is an anomaly on the landscape challenging traditional criteria for the location of regional shopping centers. Located on Hayden Island on the Oregon side of the border, it has access from only one exit in each direction off the Interstate 5 freeway. The predominantly industrial and recreational land use of the region within a five minute travel time from the shopping center results in an exceptionally small adjacent residential population. Its potential trade area is further limited by the intervening shopping opportunity for Washington residents afforded by the Vancouver central business district which lies adjacent to …

The Divorce Experience And Its Impact On The Father-Child Relationship, Susan Coffman, Ellen Lane, Erika Worth

Dissertations and Theses

This project began with the notion that an in-depth examination of perceived changes in the parent-child relationship as reported by the noncustodial father would be both beneficial to mental health professionals as well as to paraprofessional groups and organizations working with divorced fathers. The authors were aware of much related research pertaining to the children of divorced parents and also the plight of divorced mothers, but felt there to be a lack of data concerning the noncustodial father and thus identified this area as an important mental health concern.

A Study Of Behavior Changes Among Children Who Have Left The Children's Psychiatric Day Treatment Center, Julia A. Jones, Larry G. Pederson

Dissertations and Theses

This study began with the authors' interest in the Portland Public Schools' program for Emotionally Handicapped children. Originally, the researchers were interested in assessing behavioral characteristics and changes among children in that program and in relating these variables to the kind and extent of parental involvement. Such a study was particularly timely, it was felt, since some schools were considering eliminating the parent involvement component of the program and there was discussion of phasing out the entire program as it then existed in favor of "mainstreaming." The researchers soon discovered the paucity of research information relating to program effects on …

Attitudes Of Psychiatric Nurses And Aides At An Oregon State Hospital Toward Homosexuality, Don Andersen

Dissertations and Theses

Homosexuality is something which has been a part of almost every society throughout history. In western society this has been a subject of secrecy and taboo. Throughout our history homosexuals have been persecuted and forced to hide their sexual identity. The effects of this on an individual should be something of concern to professionals in the mental health field.

While in the past there has been little knowledge of homosexuality, and no self-expression on the part of homosexuals, there has, in recent years, been growing information and expression. The effect of this change on mental health workers is what this …

Analysis Of A Gravity Traverse South Of Portland, Oregon, Terry Dean Jones

Dissertations and Theses

The state gravity maps of Oregon and Washington show a gravity high centered south of Portland, Oregon and a gravity low in the Tualatin Valley to the west disrupting the regional gravity gradient which is controlled by crustal thickening. Detailed gravity surveys done in the Portland area are consistent with the state gravity maps but show considerably more detail. Quantitative interpretation of this data has provided new information on the subsurface structure in this area; recent work has yielded corroborative evidence for a fault zone bounding the east side of the Portland Hills, and has indicated the presence of faults …

The Maximum Duration Of Phonation Of /A/ In Children, Kerry Lewis

Dissertations and Theses

Measurement of maximum duration of phonation has been suggested by several voice experts as a clinical tool for assessing vocal function. Most of the investigations of maximum phonation time have been conducted using adult populations. exceptions to this can be found in the studies by Launer (1971) and Coombs (1976). An apparent need, therefore, existed to investigate maximum phonation time in children.

The present study was designed to investigate the affects of age, sex, height, weight and vital capacity on the maximum duration of phonation of sustained /a/ in children eight and ten years of age when controlling for pitch …
