The R-Stick Appliance As A Device To Facilitate The Phoneme /R/, Rosemary Leblanc

Dissertations and Theses

One of the most common articulation errors made by children is on the phoneme Ir I. Treatment techniques for this sound have varied and have included the stimulus approach (Van Riper, 1972), phonetic placement techniques (Scripture, 1923), the sensory-motor approach (McDonald, 1964), the motokinesthetics approach (Young & Hawk, 1938), and sequential programming approach (Shriberg, 1975; Wood, 1988), to name a few. An integral part of many of these treatment methods is the use of the auditory stimulation. An innovative technique using a prosthetic device to facilitate the production of Ir I was used by Leonti, Blakeley, and Louis (1975), in …

The Particular Nature Of Long-Term Lesbian Relationships, Karen Marie Freeman

Dissertations and Theses

The purpose of this thesis was to examine the characteristics of long-term lesbian relationships (operationally defined as five or more years) and to compare these characteristics with prior findings on short-term or term non-specific lesbian relationships. Several studies that have been done made assumptions about the nature of lesbian relationships based on data gathered from women in brief relationships (Caldwell and Peplau 1984; Elise 1986; Gordon 1980; Krestan and Bepko 1980). This study was designed to examine whether or not lesbians in long-term relationships might have different interpersonal relational dynamics, just as married heterosexual couples have been shown to have …

The Use Of Faceplate Assemblies As Facsimiles Of Custom Hearing Instruments, James A. Fenwick

Dissertations and Theses

Custom-designed hearing instruments comprise the majority of those dispensed in the United States today. Because of their custom nature, there has been no means of evaluating them until they have been completed. There would be advantages to evaluating custom instruments prior to their completion. This study investigates a means of evaluating custom instruments prior to their final assembly into the customized shell. This is done by having the subject listen to the circuitry of the instrument while it is still mounted on the faceplate, which is accomplished by coupling the faceplate assembly to the subject's ear with foam earplug. To …

Math Anxiety, Coping Behavior, And Gender, Sandra Joy Grossmann

Dissertations and Theses

Non-math majors enrolled in lower-division math courses at an urban university were surveyed on their math attitudes, coping behaviors, and math anxiety (MATHANX). The Revised Ways of Coping Checklist (RWCC), Revised Math Anxiety Rating Scale, and other questions were presented to 30 men and 32 women. Hierarchical regressions showed that after controlling for attitudinal covariates, emotion-focused coping behaviors (EMOTFOC) were strongly associated with MATHANX (F(5,54)=18.66, 12 < .0001), but problem-focused coping behaviors (PROBFOC) were not. The RWCC subscale most highly correlated with MATHANX was Wishful Thinking (r = .70, p < .0001). Ss were then dichotomized on PROBFOC and EMOTFOC, providing four behavioral groups. An ANCOVA controlling for attitudinal covariates showed behavioral group membership significant with respect to MATHANX (F(3,58)=6.07, p < .001), and an ANOVA revealed that students who reported high EMOTFOC coupled with low PROBFOC experienced the greatest MATHANX (,E(3,58) = 12.66, p < .0001).

Males and females reported virtually identical MATHANX (M=36.30 for males, 36.44 for females), and the only significant gender difference was for avoidance coping, which was used more by males (F(1,60) = 5.43, p < .03]. Results from this study suggest that fewer gender differences may exist in MATHANX and coping than have been found in the past. Additionally, this study identifies the need for future research to determine whether EMOTFOC is the behavioral component, or one of the determinants, of math anxiety.

A Comparison Between Trained Ear Estimation And Orthographic Transcription When Measuring Speech Intelligibility Of Young Children, Nancy Kay Sugarman

Dissertations and Theses

When the primary mode of communication is speech, the crucial ingredient for successful communication is intelligible speech. The speech of children with disordered phonologies is often unintelligible. Accurate and reliable measurement of speech with compromised intelligibility is essential if appropriate treatment procedures are to be chosen and implemented. The focus of this investigation was the measurement of speech intelligibility in young children. The purpose of this study was to investigate the relationship between the subjective method of trained ear estimation and the objective method of orthographic transcription when measuring the speech intelligibility of young speakers with a wide range of …

The Effects Of Type Of Child Care Arrangement And Satisfaction With Care On Employee Job Satisfaction And Absenteeism, Hanh Hong Nguyen

Dissertations and Theses

This study examined the effects of different types of child care arrangements (i.e., care by relatives; care by nonrelatives; self-care by child; and care by day care centers) and satisfaction with care on employee absenteeism and job satisfaction. A 53% response rate was obtained from a questionnaire administered to 501 classified staff employees at Portland State University. Only responses from employees with children under the age of 18 living at home were used. Eighty-six employees met this selection criterion.

It was hypothesized that parents using self-care by child would have the highest absences, followed by parents using day care centers, …

Impact Of Goal-Setting On Motivation As Affected By The Joint Influence Of The Attributional Dimensions Of Causality, Stability, And Control, Nancy Davis Hodges

Dissertations and Theses

A systematic, empirical study conducted in eight hospital operating rooms found that employees often select opportunity-dependent goals. These goals are self-set or chosen by the individual, but the opportunity to perform the goal chosen is dependent on others. For example, "learn to circulate on total joint surgeries" is a self-set, opportunity-dependent goal. The individual must be assigned to that job. It was found that when this type of goal is chosen and the individual is not given the opportunity to perform it, the individual attributes the failure to external causes. This failed opportunity-goal type was significantly related to lower motivation, …

A Comparison Of The Cohesion In The Expository Discourse Of The Optimally-Healthy Young-Old And The Optimally-Healthy Oldest-Old, Penni Gay Siemens

Dissertations and Theses

The group of people aged 85 years and older is the fastest growing chronological population on the United States (Neal et al., 1993), and while a considerable amount of research has focused on the language of the elderly (those over 65 years), relatively little study has focused specifically on those aged 85 and older. This study is valuable in that it includes a large sample of optimally healthy people aged 85 and older. This sample of the optimally-healthy oldest-old will help define what changes, if any, are a function of age alone and what changes are clinical (associated with some …

Modeling Music With Grammars: Some Examples From Balinese Kotekan, Janet Tom Cowal

Dissertations and Theses

What is the relationship of music and language? Analogies and comparisons of music and language are plentiful in various types of literature. For researchers in the cognitive sciences, the importance of organization, patterning, and structuring of sounds is a common theme in analyzing both language and music. With the success of generative grammars for languages, a number of researchers have used similar kinds of grammars to describe or model particular aspects of music. In addition, researchers are interested in possible universals in musical grammars. However, while grammars of non-Western musics have been written, most of the work has been based …

"I Don't Speak My Own Language": Ethnicity Among The Malayalees Of Singapore, David L. Moore

Dissertations and Theses

This thesis is an ethnographic examination of the significance of Malayalee ethnicity in Singapore. Ethnic identity is important in the daily lives of Singaporeans, due in part to the government-directed public focus in Singapore on the ideal of multiculturalism through which it is asserted that to be Singaporean, one must be, in the main, Chinese, Malay, or Indian. But other identities, such as Malayalee, a subset of the larger category "Indian", have not decreased in importance. They, in fact, remain important in identifying what kind of Chinese, Malay, or Indian a person is, as Chinese, Malay, or Indian identifies what …

Changing Values: A Study Of The Shift In Cultural Values And Perceptions Of U.S. High School Students Following Orientation And Exposure To Russian Culture, Linda Sue Warnock

Dissertations and Theses

When cultural values differ, it is difficult for people not to judge one another's behavior on the basis of their own individual and/or cultural values. Given the profound differences in Russian and American culture, the question of what happens when these two cultures interact comes to mind.

The purpose of this study was to describe the relationship of culture specific orientation, coupled with a two week sojourn in Russia on the sojourners' perceptions of cultural values. The sojourners were high school athletes participating in the first part of a Russian - American Track and Field Exchange.

In order to ascertain …

Technological Organization And Sedentism: Expedient Core Reduction, Stockpiling, And Tool Curation At The Meier Site (35co5), Stephen Coursault Hamilton

Dissertations and Theses

The Meier site fine-grained lithic assemblage was used to test the hypothesis that a sedentary group will rely heavily on expedient lithic technologies because they stockpile raw material at the residence. At Meier, expedient core reduction provided blanks for a significant number of curated and expedient tools. I propose that sedentism (stockpiling) minimizes energy investments in raw material procurement and blank production while maintaining the ability to efficiently make both curated and expedient tools. Investment in curation is limited to a few tool classes with specialized functions, not transportable design variables.

Perceived Communication During Organizational Change, Paula Blunck

Dissertations and Theses

Organizational change often involves the creation of work teams. This research examines how the creation of self-managed work teams within a particular organization affects perceived communication. Previous research suggests that self-managed teams would socially construct a different view of the organization especially as it relates to power than would those in traditional organizational departments. Attitudes about communication and power within the organization are analyzed in nine self-managed teams and five traditional departments. This analysis is conducted through both qualitative and quantitative means. Group comments and discussions are used in a qualitative analysis. Multidimensional scaling is used to reveal underlying attitudinal …

Illness And The Treatment Response: The Patient's View, Nina Patricia Van Es

Dissertations and Theses

In American society, where the biomedical profession is institutionalized and its therapies dominate health care, a decision to deviate from prevailing norms can be considered remarkable. Yet research done by Eisenberg et al. (1993) found that unconventional or alternative medicine had an "enormous presence" in U.S. health care and that one in three persons had utilized an unconventional therapy in 1990. The objective of this thesis was to explore this phenomenon. Individuals who had used alternative and biomedical intervention to treat a disorder were recruited through practitioners of alternative therapies. Through semi-structured interviews, case histories focusing on the illness trajectory …

The Preferred Learning Styles Of Greek Efl Students And Greek Efl Teachers, Debra Jane Gregory

Dissertations and Theses

The purpose of this study was to identify the preferred learning styles of Greek EFL students and teachers in Greece. The learning styles examined were visual, auditory, kinesthetic, tactile, group and individual. The study was conducted at a private English language school in Piraeus, Greece. Ninety-two Greek EFL students (33 male and 59 female) ranging in age from 13 to 22, and 11 Greek EFL teachers (3 male and 8 female) ranging in age from 22 to 52 constitute the sample. The study used the self-reporting learning style questionnaire that Reid (1987) developed to measure the preferred learning style preferences …

Planning For Academic Success: Survey Of University Professors' Assessments Of Non-Native Students' Language Skill Needs, Carol Bondurant Sloan

Dissertations and Theses

The purpose of this study is to examine which language skills university professors believe are most essential for academic success in Portland State University classes. The study can shed light on a question for future research: Do current academic ESL classes at Portland State University teach the necessary skills to help international students maximize their second-language learning potential in university-level courses. Enrollment statistics for 1993 I 94 show 53 percent of the 815 international students declared majors in two programs: the school of Business Administration and the school of Engineering and Applied Science. This study asked 31 instructors from business …

Vocabulary Learning For Short-Term Esl Students: A Comparison Of Three Methods, Michael William Bess

Dissertations and Theses

Long-term studies with both native and non-native speakers of English have shown that vocabulary can be learned passively or "incidentally" simply through the act of reading, even through reading for pleasure. Generally, studies of incidental vocabulary learning have tested subjects' knowledge of words learned after reading novels or other longer works of prose fiction. Eighty-four students from a short-term ESL program participated as subjects in this study. Subjects were divided into three treatment groups and one control group. All subjects were given a 100-i tern word-recognition pretest, containing 45 test words and 55 dis tractors. The three treated groups were …

A Comparative Study Of Phonemic Segmentation Skills In First Grade Children With Normal, Disordered, And Slow Expressive Language Development, David J. Andrews

Dissertations and Theses

Children with slow expressive language development often catch up to their normally developing peers in expressive language, but may still exhibit difficulties with metalinguistic skills. Research shows that children who have difficulty with phonemic awareness also have difficulty with reading, which is important for success in school. Speech-language pathologists assist children who have difficulty with expressive oral language and facilitate language development in children who have difficulties with learning metalinguistic skills, such as phonemic awareness.

The purpose of the present study was to compare the phoneme segmentation skills in three groups of children: (a) children with a history of oral …

Soil Properties And Behavior Of Earthflows In The Mt. Hood National Forest, Oregon, Douglas Andrew Smith

Dissertations and Theses

Soils from two active earthflows, two earthflow deposits, and three non-earthflow landforms are examined to determine if a connection exists between near-surface soil properties and rates of earthflow movement. The study area is located in the Clackamas Ranger District of the Mt. Hood National Forest in the northern Oregon Cascades. Its geology consists of clay-bearing volcaniclastic formations overlain by unaltered flows of andesite and basalt, a combination that contributed to large-scale landsliding during the late Pleistocene. Deposits from these landslides now cover much of the valley floor, and it is from these deposits that earthflows tend to mobilize. The main …

Decentralization Of Urban Service Activities: An Empirical Study, Wonseon Kyung

Dissertations and Theses

Post-war metropolitan development in the United States has been mainly due to suburban growth which resulted in dispersal of population, retailing, manufacturing, wholesaling and services. What is known about service suburbanization is primarily derived from survey research on location choices done in localized cases. There has been no comprehensive work done using secondary data on revealed behavior.

This dissertation attempts that comprehensive study. The research analyzes the dynamics of locational structure of services in U.S. metropolitan areas from 1969 to 1989. The descriptive analysis of changes in the location coefficients provides evidence to demonstrate a spatial shifting of consumer oriented …

A Bootstrapped Regression Model Of Psychological Predictors Of Success In Naturopathic Medical School, Christa Claire Louise

Dissertations and Theses

In response to a need for more primary care physicians and patients' growing attraction to alternative health care, greater numbers of individuals are applying to naturopathic colleges. With increasing numbers of applicants, better methods of predicting potential effectiveness as an N.D. are needed. This study examined factors (both academic and psychosocial) that best predict success in naturopathic school.

Demographic, academic, and psychosocial survey data were collected from thirty-three students who had just completed their second year of naturopathic medical school. This information was correlated with scores on the NPLEX Basic Science exams which were taken the following summer.

Because of …

Culture And Consensus: The Use Of Mathematical Models To Examine A Culture Of Sports In The Portland Metropolitan Area, Phillip M. Crawford

Dissertations and Theses

The question of what constitutes a culture has often been answered in one phrase: shared knowledge. Recent developments in both the theory and mathematics of examining this shared cultural knowledge allow researchers to produce mathematical models of informants' knowledge and perceptions of the culture they belong to. Many studies in cognitive anthropology have utilized these theoretical and mathematical tools: the present research sought to integrate a research design (based on the theory and mathematics mentioned above) with a relatively new cultural domain: the culture of sports.

Three main question pertaining to cultural knowledge were addressed in this research:

1. Did an …

Questions-Asking Strategies Of Aphasic And Normal Subjects, Sharla Rae Harvey

Dissertations and Theses

Problem-solving abilities of individuals with aphasia have received limited attention in their assessment and remediation. At this time, there is substantially more information available on the linguistic performance of persons with aphasia than on their cognitive processing performance. Assessment of problem-solving abilities in this population has typically used tasks with low verbal loadings. However, both linguistic and cognitive competence are required for effective communication and activities of daily life.

The purpose of the present study was to determine if mild-to-moderate subjects with aphasia differed in their question-asking strategies as compared with normal subjects. A modification of Mosher and Hornsby's (1966) …

An Assessment Of The Riparian-Influenced Salmonid Habitat Features Of Johnson Creek, Portland, Oregon, Andrew Greiff Gude

Dissertations and Theses

Pacific salmon populations in Johnson Creek, Portland, Oregon have been adversely impacted by urbanization, and by residential and agricultural land development. Ecological impacts include loss or depletion of riparian vegetation features which directly influence stream and associated salmonid ecology. This research examines the nearstream riparian zone's contribution to instream habitat complexity for anadromous salmonids in Johnson Creek. Visual surveys were conducted on over half the stream length. Five features were assessed to determine the extent of riparian influenced stream habitat including, overhead enclosure, overhanging vegetation, undercut banks, and large and small woody debris and root wads. The stream survey showed …

The Spatial Distribution Of Ground Stone Tools As A Marker Of Status Differentials In A Chinookan Plank House On The Lower Columbia River, John William Wolf

Dissertations and Theses

Social status was an integral part of the social structure of Northwest Coast societies. The presence of ranked social structures and household space based on rank is reported in the ethnographic literature. Archaeologists have long searched for independent and verifiable means to infer social structure from archaeological deposits. Burial goods have been used to identify status differences. Do other items of material culture also reflect such differences?

The purpose of this study was to ascertain whether or not the distribution of certain tools recovered from a Chinookan plank house on the lower Columbia River paralleled the household residence location that …

The Impact Of Collective Bargaining On The Civil Service Merit System In Oregon, David K. Blanchard

Dissertations and Theses

This study examines the impact of collective bargaining on the civil service merit system in the State of Oregon. Four topics of current interest are explored. The first is a discussion of the status of collective bargaining and the civil service merit system legislation. The second topic is an analysis of the extent to which the day-to-day administration of public sector personnel functions is determined by the relative influence of collective bargaining agreements and civil service rules. The third is the impact of the collective bargaining model on the integrity of the merit principle. The final topic addressed by this …

Total Quality Management: The Case For The Public Sector: A Comparative Study Of The Implementation Of Total Quality Management In Three Health Care Organizations, Zayed Mohammed Abu

Total quality management [TQM] is an approach to improving the competitiveness, effectiveness and flexibility of the whole organization through the improvement of the organizational processes and those who perform them. There has been a rising interest among public sector professionals in examining the applicability and usefulness of TQM methods to public organizations. This research provides descriptive information about the experience of three health care organizations that vary in terms of ownership, whether being publicly or privately owned, with implementing TQM. Participants at these organizations were interviewed, and/or surveyed and observed. The study provides a narrative description of each organization's experience …

The Role Of The Chinese News Media In The 1989 Pro-Democracy Movement, Mei Liao

Dissertations and Theses

This thesis examines the role of the Chinese news media in the 1989 pro-democracy movement. The three functions of this thesis are: 1) to provide evidence of changes in the pro-democracy movement; 2) to identify corresponding changes in the press coverage of the movement; 3) to examine what relationship exists between changes in the movement and changes in the press coverage of the movement.

Portland's Multifamily Recycling Program: A Study Of Coproduction Policy Implementation And Citizen Involvement, William Barry Messer

Dissertations and Theses

This study is on coproduction as a governing policy instrument. Coproduction can be understood as the joint production of services by local officials and individual citizens intended to raise the quality and or amount of service provision. The concept of coproduction as developed in this study suggests that urban services are not simply created by officials and delivered to a passive public. Rather that actions of citizens are an integral part of the service production process. The study purposes are two-fold: (1) to construct a model of coproduction which provides a basis by which citizen involvement in the provision of …

Aids-Preventative Behaviors And The Psychological Costs Of Behavior Change, Howard Balshem

Dissertations and Theses

This study examined the effects of behavior change on psychological health among gay and bisexual men of Portland, Oregon who were at risk for contracting AIDS. Cross-sectional self-reports of personal experiences were obtained in Summer, 1991. Sexual behaviors were used as predictors of self-efficacy, depression, anxiety, and subjective well-being. Adopting safer sexual behaviors was psychologically more costly than continuing to engage in high risk behaviors, or long-term adherence to safer behaviors. Behaviors amenable to short-term change differed from those conducive to long-term maintenance. Behavior change was also found to have a beneficial effect on self-efficacy.

These findings suggest that behavior …
