Care, Need, And Conceptions Of Love: A Reexamination, Janet Gruwell Morris

Dissertations and Theses

The present study examines the roles need and care play in such positive interpersonal attitudes as love, liking, attraction, and friendship, by both replicating and extending a 1982 study by Steck, Levitan, McLane, and Kelley. Subjects were presented with slightly revised Rubin Love Scales which were filled out as if by persons involved in relationships, and were asked to judge how much each hypothetical person loved, liked, was attracted to, and felt friendly toward their partner. In fact, the love scales had been divided into three components, i.e. need, care, and trust, and were filled out with each component at …

Effects Of Stress Management Instruction And Anxiety Monitoring In Adult Day Treatment Population, Jack Blanton Wills

Dissertations and Theses

This study examines the effectiveness of a particular stress management intervention with adult outpatients diagnosed as chronic schizophrenics. The setting for the study was the Portland, Oregon, Veteran's Administration, Outpatient Clinic, Day Treatment Center. The intervention was composed of two factors; 1) stress management training and 2) Behavior-Graph Instruction. Both of these were presented using a psychoeducational model of classroom instruction, role play, and discussion.

The Chemistry Of Novel Chromium(Iv) Systems And Fluorinated Hypochlorites, Joseph Onuorah Udeaja

Dissertations and Theses

Chromium(IV) has been of interest for some time because of its role as an intermediate in chromic oxidation reactions. Since there are not a great number of stable tetravalent chromium complexes known, and the use of such species as oxidizing agents has not been widely explored, the preparation, isolation and characterization of new stable tetravalent chromium species may allow chemists the opportunity to more fully understand the role which tetravalent chromium plays in oxidation reactions. The present study thus involves the synthesis of Cr(OC₄H₉)₄ and other Cr(IV) derivatives and the use of Cr(OC₄H …

Tephrostratigraphy Of The Middle Eocene Chumstick Formation, Cascade Range, Douglas County, Washington, Matthew John Mcclincy

Dissertations and Theses

This study outlines the ash (tuff) bed stratigraphy (tephrostratigraphy) in the middle Eocene Chumstick Formation of central Washington. The tuff beds provide local marker beds enabling interpretation of the stratigraphy and structure of the formation. The chemical signature of these units provides the basis on which the units can be traced over broad areas in the basin of deposition. Correlations of tuff beds were obtained over distances of 41 km.

The tephrostratigraphy of the Chumstick Formation consists of nineteen tuff marker beds. Seventeen of these units are chemically characterized in this study. Ten elements were used to fingerprint these tuff …

A Contextual Analysis Of Selected Communication Strategies Associated With Dyadic And Situation Characteristics: A Field Study, Gisele Marie Tierney

Dissertations and Theses

A contextual analysis investigation of related communication acts is concerned with the multidimensional nature of human interdependence. The communication strategy is a category of relational communication acts that can be viewed as one of the ways in which interactants promote or maintain a working consensus and enhance interpersonal discovery. Strategy use is motivated by the nature of the relationship rather than by the speaker's conscious attempts to direct outcomes.

After The Sixties: Anthropology In Sixth Grade Social Studies Textbooks, Christine Skei Rossi

Dissertations and Theses

During the 1960s, anthropology was an important part of the social studies curriculum. This study explores the question of whether twenty years later, anthropology is still an important part of primary and secondary school curricula and textbooks. To answer that question, the author used content analysis to analyze 13 sixth grade social studies textbooks for their anthropological content. Results of the research indicate that there is very little anthropology in the texts, the same topics and concepts are covered in most of them, and that most of the anthropological material is narrative or descriptive in form rather than theoretical. The …

Hemodynamics During Pregnancy: A Model For Cardiac Enlargement, David James Mendelson

Dissertations and Theses

Cardiac output increases by 30-50% during mammalian pregnancy. This increase is reflected by elevation in both heart rate and stroke volume. The primary mechanism of increased stroke volume appears to be cardiac enlargement, rather than increased preload, afterload, or contractility. Animal studies have shown that enlargement of the heart occurs prior to an increase in uterine blood flow during pregnancy and this type of enlargement can be mimicked by sex steroid administration.

Systemic vascular resistance greatly decreases during pregnancy and with sex steroid administration. It has been postulated that systemic vascular resistance may be a signal for heart size changes. …

Comparative Self-Monitoring Behavior And Recall Of Verbal And Nonverbal Interactional Information About Partner In Conversations With Ablebodied And Disabled Partners, Doris L. Werkman

Dissertations and Theses

When strangers meet, there is a high level of uncertainty due to the infinite number of possible alternatives in behavior between the two people. Previous research indicates that communicators will attempt to reduce the level of uncertainty by using available verbal and nonverbal information of the other, by seeking similarities with the other, and by observing the situation itself. This information is used to predict attitudes and beliefs, as well as to attribute characteristics of the other. Other studies indicate that a person will increase her level of self-monitoring activity when the level of uncertainty is increased.

Analysis And Prediction Of The Water Temperature Of The Mckenzie River, Oregon Using The Equilibrium Temperature Approach, R. Peder Hansen

Dissertations and Theses

A one dimensional, steady flow, unsteady temperature model is used to evaluate the effects of two U.S. Army Corps of Engineers (COE) dams and resulting reservoirs on hourly water temperatures of the mainstem McKenzie River from Delta Park (RM 62.1) to Leaburg Dam (RM 38.8). Both COE projects are on tributaries to the McKenzie River and at present have only bottom withdrawl capabilities.

Water temperatures were simulated using the equilibrium temperature approach with air temperature used to estimate equilibrium temperature and also using computed hourly equilibrium temperature. Results obtained using computed equilibrium temperatures were less satisfactory than results using air …

Cooperative Responses In Competitive Soccer, Rodney Gordon Williamson

Dissertations and Theses

The purpose of this study was to discover patterns in intra-team cooperation (passing) versus individualistic behavior (dribbling) across various age and gender groups. A behavioral coding scheme for soccer players in possession of the ball was designed to tabulate team responses of passing or dribbling behavior in a four-a-side indoor tournament. A total of 32 teams, 18 male teams and 14 female teams, participated in four age brackets. A multi variate analysis of variance (MANOVA) generated one significant result for age and passing behavior. This supported the first hypothesis that intra-team cooperative behavior increased with age. Due to the nonorthogonal …

A Comparison Of Behavioral Problems Between Speech And/Or Language Impaired Children And Normal Children, Jeannie S. Botelho

Dissertations and Theses

The questions posed in this study were: 1) Is there a significant difference in the prevalence of behavioral problems between speech and/or language impaired children and normal children as reported by parents and teachers? and 2) Is there a significant difference in the types of behavioral problems between speech and/or language impaired children and normal children, as reported by parents and teachers?

A Comparative Study Of Three Language Sampling Methods Using Developmental Sentence Scoring, Cheryl Diane Dong

Dissertations and Theses

The present study sought to determine the effect different stimulus material has on the language elicited from children. Its purpose was to determine whether a significant difference existed among language samples elicited three different ways when analyzed using DSS. Eighteen children between the ages of 3.6 and 5.6 years were chosen to participate in the study. All of the children had normal bearing. normal receptive vocabulary skills and no demonstrated or suspected physical or social delays. Three language samples. each elicited by either toys. pictures. or stories. were obtained from each child. For each sample. a corpus of 50 utterances …

The Grammatic Closure Subtest Of The Itpa As A Screening Device, Cathy Newquist

Dissertations and Theses

Identification and selection of a speech-language caseload in the school setting can be a challenging task. The initial stages of caseload selection are usually in the form of a screening procedure. Although speech-language information is gathered at that time, information about its relationship to each student's academic status is usually not obtained. Such information would be useful in a setting that requires the provision of special education services to be justified from a basis of academic need.

The Illinois Test of Psycholinguistic Abilities' (ITPA) Grammatic Closure subtest has been correlated to academic and intellectual measures through various studies. …

Attitudes Of Otolaryngologists Towards Speech Pathologists Working With Voice Disordered Clients, Judith Patricia-Bader Cross

Dissertations and Theses

This study was designed to collect information about the working relationship of otolaryngologists with speech pathologists who provide service to voice disordered clients.

Adsorption Of Aminopyridines To Phosphatidylserine Vesicles, Colin Wright

Dissertations and Theses

Intrinsic association constants were determined for a series of aminopyridines on phosphatidylserine vesicles, through determination of electrophoretic mobility. The magnitudes of the constants were such that depolarization of the nerve terminal through binding to negative phospholipids seems unlikely to occur. The aminopyridines all had association constants between one half and one sixtieth the association constant of calcium. The aminopyridines probably block potassium channels in their enhancement of synaptic transmission.

An interesting correlation was noted in that the ranking of the aminopyridines in terms of their affinity for these lipids was approximately the same as the ranking of their enhancement of …

The Effect Of Order Of Presentation And Experience On Problem Solving, Edward Bruce Versteeg

Dissertations and Theses

The effects of order of presentation and amount of experience on errors and solution time were investigated. An interactive narrative puzzle was presented on a computer screen to 60 undergraduate students. Solution of the problem involved the integration of two path segments. Subjects in the Forward Condition were presented the path segments in the order in which they had to be traversed for solution. Subjects in the Backward Condition were exposed to the opposite order of presentation. Amount of experience was varied by permitting one, three, or five readings of the narrative.

The Engineering Geology Of The Fountain Landslide, Hood River County, Oregon, Susanne L. D'Agnese

Dissertations and Theses

The Fountain Landslide located along I-84, five kilometers east of Cascade Locks, Oregon has moved periodically for over thirty years. Aerial photographs taken prior to recorded movement of the landslide show the headscarp of a large preexisting landslide. In 1952 a cut was made into the toe of the landslide to straighten Highway 30. The recorded movement history begins at this time. Stabilization procedures in the late 1950's focused on dewatering the slide mass. Movement had nearly stopped by 1957. A deeper cut was made into the toe of the landslide in 1966 to widen the highway to the four-laned …
