Language Development And Visual-Motor Integration In The Preschool Child, Andrea Lynn Perry Graham

Dissertations and Theses

The purpose of this study was to compare the visual-motor integrative abilities of preschool children with their articulatory and syntactical development. Two questions were posed: Do children having accelerated visual-motor integrative skills perform at a higher level than children having delayed visual-motor integration skills in 1) their articulation proficiency, and 2) their syntactical abilities?

Geology And Hydrothermal Alteration, Glass Buttes, Southeast Oregon, Dulcy Annette Berri

Dissertations and Theses

The Glass Buttes volcanic complex consists of many domes and individual vents that erupted both rhyolitic and basaltic lavas during the late Miocene to early Pliocene. The east half of the complex, in the vicinity of Little Glass Butte, contains interfingering, finely flow-banded rhyolite and black obsidian flows. The youngest unit, an obsidian, has been dated at 4.9 m.y. East of Little Glass Butte lie two northwest-trending ridges, Antelope and Cascade Ridges, composed of two or more overlapping exogenous domes that formed along northwest-trending faults.

An Investigation Of The Effects Of Self-Disclosing Communication On Attraction-To-Group In The Small Group Setting, Pamela Walker Vredevelt

Dissertations and Theses

A review of the literature on self-disclosure and small group communication showed that few investigations dealt with the effects of disclosing communication on small group process. The present study was conducted in order to assess the effects of the frequency of self-disclosure within small groups on the members' overall attraction to the group. 120 subjects were selected from the East Hill Church senior high youth department in Gresham, Oregon. Subjects were placed at random into ten small groups with twelve members each which met for one-half hour per week for six consecutive weeks. All group communications were audio tape recorded. …

The Descriptive Function Of Language: Changes With Age And Pressure To Inform, Eve Susan Liebman

Dissertations and Theses

Currently language is viewed as a multi-dimensional construct, consisting of three interrelated components; content, form and function (Bloom and Lahey, 1978). In recent publications, language function has been referred to as pragmatics (Prutting, 1979). The essence of pragmatic theory is that language is used functionally in social contexts, to accomplish specific types of communication (Wood, 1981). One such communicative function is referred to as the informative function, which occurs when a speaker provides ideas and information to others, as in describing, naming and giving examples {Wood, 1981). It is not clear, however, when children become competent in making specific, clear …

A Comparison Of Two Language Screening Instruments In Two Populations, Karen Kumpula-Lacey

Dissertations and Theses

Screening has been suggested as the most efficient method to find students with potential language problems (Neidecker, 1980). Based on the need for a standardized adolescent language screening tool, Prather, Breecher, Stafford, and Wallace (1980) developed the Screening Test of Adolescent Language (STAL). This is a six to eight minute test with twenty-three items which examine vocabulary, auditory memory span, language processing, and proverb explanation. Following an item analysis of the STAL, Prather, Brenner, and Hughes (1981) derived the Mini-Screening Test of Adolescent Language (M-STAL). This test contains five items from the STAL and requires one minute to administer.

A Geochemical Study Of The Rhododendron And Dalles Formations In The Area Of Mount Hood, Oregon, Marshall W. Gannett

Dissertations and Theses

The Miocene Rhododendron and Dalles Formations in the Mount Hood area are accumulations of chiefly pyroclastic andesitic material, largely confined to the Dalles-Mount Hood syncline. These very similar units are geographically separated by overlying andesites including the present Mount Hood cone, and past workers have suspected that they may share a common source. Prior to this study, few geochemical data were available for the Rhododendron and the Dalles Formations, compared to the well studied Columbia River basalts underlying them and the overlying Pliocene andesites. This geochemical study was designed to investigate certain aspects of the Rhododendron and Dalles Formations such …

A Comparison Of The Effects Of Non-Operant And Operant Carryover Techniques For /L/, Michelle Ann Tremblay

Dissertations and Theses

Developing strategies to promote effective carryover is one of the most difficult tasks a clinician faces. Mention has been made in the literature of possible activities to use in the clinical setting to promote carryover. Suggestion has been made in the literature that operant conditioning is a technique which can be employed to achieve carryover. The purpose of this investigation was to determine whether there is a difference in relative effectiveness between operant and non-operant techniques for achieving carryover of /l/.

Teaching Figure Drawing To Adolescents Within The Context To [I.E. Of] Imaginative Compositions, As A Means Of Increasing Artistic Confidence And Abilities, Christine Flavell Turner

Dissertations and Theses

This thesis describes a process of teaching figure drawing to adolescents which places importance on the subjective experiences of the students. Traditional figure drawing methods emphasizing the development of visual perceptual skills are integrated with activities which are designed to secure emotional participation, and develop awareness of art as a means of expression and communication. This approach seems to motivate students and to reduce the anxiety usually experienced by adolescents when they are drawing the figure.

Structure And Influence Of The Tillamook Uplift On The Stratigraphy Of The Mist Area, Oregon, Moinoddin Murtuzamiya Kadri

Dissertations and Theses

Fifty three sedimentary samples were analyzed for their minor and trace element concentrations utilizing instrumental neutron activation analysis. Concentrations of Na, K, La, Sm and Sc, and their ratios appear to establish significant trends. The data suggest a major break from a granitic-metamorphic provenance and a volcanic component dominated provenance between the Cowlitz and Keasey Formations respectively. The provenance of the Astoria Formation indicates the presence of flood basalts.

A Preliminary Investigation Of The Lithological Characteristics Of The Troutdale Formation In Portions Of The Camas, Sandy, Washougal, And Bridal Veil Quadrangles, David Lee Cole

Dissertations and Theses

The study area encompasses a region of about 80 square kilometers, centered about Corbett, Oregon. Sieve analyses suggest that the Troutdale Formation is composed of a conglomerate, a coarse-grained sandstone, and a siltstone lithofacies. Measured sections data show that 56 to 60 percent of the Troutdale Formation's exposures are composed of the conglomerate lithofacies. The coarsegrained sandstone lithofacies makes up 34 to 38 percent, while the siltstone lithofacies makes up only 4 to 8 percent. Pebble count data show that the representation of basalt varies from 69 to 100 percent, with an average of 85 percent, while quartzite varies from …

The Measurement Of Economic Diversification With Reference To Regional Unemployment, Adil H. El-Haimus

Dissertations and Theses

Over the past four years, considerable attention has been focused on the problems of high unemployment in the State of Oregon. The percentage of jobless continued to be higher than that of the nation. The depressed housing market, caused by high interest rates, coupled with an increase in the import of Canadian timber managed to reduce the demand for Oregon lumber and wood products drastically. This has resulted in an abnormally high unemployment rate in many of Oregon's counties which are dependent on the wood industry; for example, the 1980 jobless rate in Harney County reached a record high of …

A Study Of The Personality Characteristics Of Tinnitus Patients, Gloria E. Reich

Dissertations and Theses

A short form of the Minnesota Multiphasic Personality Inventory was administered to 146 clinical patients who suffered from either tinnitus or a hearing disorder or both. Patients were assigned to four groups on the basis of their subjective complaint and their audiometric report: patients with tinnitus only, patients with tinnitus and a hearing loss where the tinnitus was the primary complaint, patients with tinnitus and a hearing loss where the hearing loss was the primary complaint, and patients who had a hearing loss but no tinnitus. The purpose of the study was to determine whether there were certain measurable personality …

Laser Induced Hydroxyl Radical Fluoresence At Atmospheric Pressure, Cornelius Yuk-Kwan Chan

Dissertations and Theses

Laser Induced Fluorescence (LIF) is one of the chief methods for detecting ambient hydroxyl radicals. To measure the absolute concentration of this important atmospheric chemical species, accurately known quenching rate constants due to the dominant gases in the air are of paramount importance. Unfortunately, these rate constants have only been measured under conditions remote from those of ambient air. This dissertation reports the measurement of the rate constants of water, argon, nitrogen and oxygen under ambient conditions. As the LIF is carried out at atmospheric pressure, the OH fluorescence life-time becomes extremely short (about 1 ns). Time Correlated Photon Counting …

Kinetics Of Proton Transport In Lipid Membranes Induced By Some Chlorinated Phenols, Ananda Ranjith Jayaweera

Dissertations and Theses

This dissertation represents an attempt to understand the mechanism of the action of pesticides derived from chlorinated phenols (pentachlorophenol, pentachlorobenzenethiol, and 2,4,5-trichlorophenol) in lipid membranes; specifically, the kinetics of pesticide induced hydrogen ion transfer in lecithin-cholesterol membranes and its relationship to uncoupling activity in energy transducing membranes. Information on pesticide induced charge transport in membranes was obtained from the measurements of steady state and transient membrane conductance and membrane potentials as a function of the composition of the aqueous phase surrounding the membrane and of membrane composition. In addition, a systematic theoretical study of a series of membrane transport models …
