The Concentration And Speciation Of Sugars In Natural Waters, Minoo Shakerin Sweet

Dissertations and Theses

Due to the importance of carbohydrates in biological systems, many efforts have been made to develop a quantitative method for analysis of carbohydrates in natural waters. The low concentrations of dissolved sugars in natural waters require a sensitive analytical method. In this study, gas chromatography of alditol acetate derivatives of sugars was investigated for quantitative and qualitative analysis of individual dissolved sugars in natural waters. The alditol acetate derivatives of sugars give only one derivative for each sugar, yielding qualitative and quantitative results.

The detection limit was 25 nM for each sugar. Because of this very low detection limit, only …

The Interruption Of The Developmental Tasks Through Pregnancy In The Female Adolescent, Suzanne Epstein, Kathleen Perkins

Dissertations and Theses

There is much information about the incidence of adolescent pregnancy yet little attention has been directed to how this process will interrupt the working towards or completion of the developmental tasks of adolescence. It is our belief that completion of these tasks is crucial in relation to moving into the next stage, adulthood.

Public interest and concern for the contemporary needs of pregnant adolescents and school age parents as a special group is still fairly novel. Survey findings revealed that adolescent parents still have great need for infant day care services, direct financial assistance, housing arrangements, education, and parenting education. …

The Clinical Application And Practical Limitations Of Bone Conducted Speech, Terry Scott Cochrane

Dissertations and Theses

The purpose of this study was to investigate the effects of increased intensity on the bone conducted speech discrimination ability of normal listeners utilizing standard audiological equipment. The NU-6 word lists were utilized to test the bone conducted speech discrimination skills of ten normal hearing subjects, 21 to 30 years of age, on standard clinical equipment. Both the hearing levels (dB HL) and the sensation levels (dB SL) of the test administration were considered. In general, it was recommended that 100 dB Hl is the most appropriate dial setting for the administration of bone conducted speech discrimination tests even though …

Ascorbic Acid, Lipid Peroxidation, And Aging, Brian Evan Leibovitz

Dissertations and Theses

The role of ascorbic acid with regard to lipid peroxidation and aging has been examined. A thorough literature analysis indicates that free radical-induced lipid peroxidation is a plausible biochemical explanation for aging. Lipid peroxidation causes cellular damage due to altered enzyme activities, error-prone nucleic acid metabolism, and membrane dysfunction, as well as the accumulation of aging pigments in the lysomes. Ascorbic acid, a water soluble free radical quencher, was examined with regard to carbon tetra-chloride-induced lipid peroxidation and in vivo aging. Carbon tetrachloride, a well-known free radical inducer, caused marked increases in the ration of oxidized/reduced vitamin C only …

1) Do mothers of language delayed children present their children with a significantly different percentage of verbal constraints (commands and question) than do mothers of normal language developing children in a play situation?

2) Do mothers of language delayed children present their children with an equal number of utterances as mothers of normal language developing children in a play situation?

3) Is the maternal mean length of response …

Cultural Values, Educational Methods And Small Group Communicator Styles In The United States And The People's Republic Of China, Lynda Lee Densem

Dissertations and Theses

The increasing contact between countries in today’ shrinking world indicates an urgent need for effective communication between cultures. Fundamental to satisfying this need is an understanding of cultural value systems--what factors have created them and how they interact within society. This paper addresses the value systems of two countries that recently have found themselves in positions of expanding contact, the United States (US) and the People's Republic of China (PRC). The value systems of the cultures are traced from their transference to the young of the cultures through formal educational systems to their effect on learning and perceptual sets. General …

The Effects Of Morning And Afternoon Scheduling On The Clinical Performance Of Severe Aphasic Adults, Judith Ann Fisher

Dissertations and Theses

Concern regarding variables which influence the performance of aphasic adults has been demonstrated in the literature. Marshall et al. (1978) found that one such variable, scheduling of intervention, influenced significantly the test performance of their subjects. They determined that the aphasic subjects performed better in the morning than in the afternoon. The purpose of the present study was to determine if performance of severe aphasic adults on easy and difficult, single-word picture-identification tasks, presented in a clinically reinforcing manner, is differentially affected by morning and afternoon scheduling.

The questions posed in this investigation were: 1) Does morning versus afternoon scheduling …

Androgen-Induced Immunosuppression, Debra Ann Weyant

Dissertations and Theses

It is well established that females are more immunocompetent than males as evidenced by higher humoral antibody titers, lowered susceptibility to infection, and more efficient graft rejection.

Furthermore, females also exhibit a much higher incidence of autoimmune disease. These observations have led investigators to believe that the male hormonal environment may play a key role in the regulation of immune response. For this reason, this study is concerned with the expression of autoimmunity and of immune function in the mouse.

This study included the New Zealand Black (NZB) mouse strain, as an animal model for human SLE, as well as …

An Investigation Of The Consistency Of Stimulus Overselection Of Autistic Children, Patricia O'Meara Walker

Dissertations and Theses

A review of the literature indicated that not all of the research in the area of overselectivity of autistic children has been in agreement. It does seem evident that some autistic children overselect. This could be the result of an attentional factor or a modality preference. This has important implications for the education of autistic children. In the light of the inconsistency of autistic children's reactions to sensory stimuli this investigator believed there was a need to determine if overselection is consistent before referring to the overselected modality as a preferred modality or comparing overselected modalities with the child's mode …

An Investigation Of Client Fluency Maintenance Between 1972-1977 At Portland State University, Pricilla Lynn Ginter

Dissertations and Theses

The use of so many different therapeutic approaches to stuttering raises frequent questions about methodology and treatment. Confidence in a methodology and treatment approach depends upon follow-up research conducted with systemic analysis of the individuals prior to treatment and following treatment.

The purpose of this study was to conduct a follow-up evaluation on R.L. Casteel's Four Stage Stuttering Program at Portland State University and to examine the degree of maintained fluency in relation to entering baseline, time in program, and exit stage.

The Design And Construction Of A Flashlamp-Pumped Frequency-Doubled Dye Laser Applicable To Long Path Monitoring Of Air Pollutants, Joel Craig Johnson

Dissertations and Theses

The subject of this thesis is the development of a laser light source which could be used in an air pollution monitor to measure the average concentration of sulfur dioxide gas over long paths (>1 km). Many of the problems encountered in designing a long-path pollutant monitor such as instrument cost and reliability, the selection of an optimum spectral region for making the measurement, and light losses due to scattering and turbulence, are considered. The result of these considerations together with a survey of available laser light sources suggested that a frequency-doubled dye laser possessed several advantages over other …

Comparisons Of The Habitual Activity Level Of Selected Women To Performance On The Bruce Multistage Treadmill Test And The Cooper 12 Minute Run Test, Teresa Carver Owen

Dissertations and Theses

The purpose of this study was to determine whether the Cooper 12 Minute Run test and Bruce Multistage Treadmill test measure the same type of cardiovascular-endurance performance when testing adult women. A second purpose was to determine whether divergent levels of habitual activity by women are reflected in the scores on each test. Four groups of habitual activity were defined and labeled as follows: non-exercisers, minimal exercisers, adequate exercisers, and more than adequate exercisers. Ten healthy women were selected as subjects in each group. Subjects ranged in age from 22 to 35 years and were within the normal weight range …

An Evaluation Of A Data-Based Sex Education Training Program For Mentally Retarded Adults, Patricia Ann Riley

The Lane Community College-Adult Basic Education (LCC-ABE) Pre/Post Test was administered to each subject when he/she began and finished the training program. The Intermittent Probe Tests were administered to each subject after instruction in each of thirteen topic areas in the curriculum. The main conclusions were that: (a) the subjects significantly increased their sexual knowledge after training; (b) class, sex, ability level, age, type of residence, and length of time in that …

The Federal Writers' Project In Oregon, 1935-1942: A Case Study, Thomas James Ptacek

Dissertations and Theses

The Federal Writers’ Project was created in 1935 as part of the Works Progress Administration. This project represented an example of the highest evolution of work relief philosophy of the New Deal during the depression of the 1930's. Unlike previous work relief programs, the Federal Writers' Project sought to employ people in their chosen profession. This task was accomplished with the establishment of writers' projects in each state under the guidance of a national office. The major goal of these individual projects was to research, write and edit a state guidebook. This current study surveys previous research on this program …

Field work in the southeast quarter of the Dutchman ·Butte Quadrangle, which lies within the Klamath Mountains geomorphic province of southwestern Oregon, was completed during the summers of 1973 and 1974. The objectives of the study were fourfold: (1) to produce a geologic map of the southeast quarter of the Dutchman Butte Quadrangle, (2) to determine the nature of the contact between the Dothan and Rogue formations, (3) to construct a stratigraphic column of the Dothan Formation in the area, and (4) to attempt to determine the nature of the deformation occurring in the area.

Welfare Stigmatization And The Elderly: The Case Of The Supplemental Security Income Program, Peter Jic-Leung Man

Dissertations and Theses

Policy-makers and others historically have assumed that welfare programs should give assistance to the poor and carry stigma. This attitude in part developed from the English Poor Laws tradition in which poverty was considered a negative condition. Labeling theory has often been used to explain the process of welfare stigmatization. Once an individual is labeled as a deviant, such as a welfare recipient, a self-fulfilling prophecy is initiated. Others perceive and respond to the individual as a deviant and the individual also internalized the stigma attached to such a role. The stigma attached to public dependency becomes an outcome of …

Affirmative Action Programs In Social Service Agencies: Status Of The Female M.S.W., Geraldine Ann Berg

Dissertations and Theses

Job status and salary inequities between men and women have only recently been documented. The federal government, over the past few decades, through various acts and executive orders, has created legislation to prohibit discrimination based on race, sex, color, religion or national origin in all employment practices. The question is to what extent this legislation has permeated social service agencies and affected their employment patterns, particularly with respect to administrative positions.

In 1976, the Women's Issues Committee of the Oregon Chapter of the National Association of Social Workers (NASW), addressed this question by initiating a study of social work employment …

Public Sector Collective Bargaining And Impasse Resolution: An Analysis Of The Oregon Fact-Finding Process, Martin David Haney

Dissertations and Theses

The topic of this dissertation is the fact-finding stage of Oregon's public sector impasse resolution procedure. The use of fact-finding has dramatically increased because of the recent and rapid growth in public sector collective bargaining, and the resulting increase in public sector strikes. Beginning in 1962 with John F. Kennedy's Executive Order 10988, a series of federal and state laws were passed granting and expanding collective bargaining rights to public employees. Many of the state laws resemble the private sector model provided under the Labor Management Relations Act of 1947 (Taft-Hartley); however, the use of the strike as a weapon …
