Effect Of Ethanol On Thermoregulation In The Goldfish Carassius Auratus, Candace Sharon O'Connor

Dissertations and Theses

In an attempt to elucidate the mechanism by which ethanol affects vertebrate thermoregulation, the effect of ethanol on temperature selection was studied in the goldfish, Carassius auratus. Ethanol was administered to 10 to 15 g fish by mixing it in the water of a temperature gradient. The dose response curve was very steep between 0.5% (v/v) ethanol (no response) and 0.7% (significant lowering of selected temperature in treated fish). Fish were exposed to concentrations of ethanol as high as 1.7%, at which concentration most experimental fish lost their ability to swim upright in the water. At concentrations higher than …

Dissertations and Theses

Over the past 15 years, mental health professionals have seen an increasing number of Vietnam combat veterans suffering from stress disorders resulting from the trauma of combat and continued exposure to life threatening situations. Prior to 1980, professional repudiation of and hostility toward Vietnam veterans and toward a clinical reality of Post Traumatic Stress Disorder was common while nondiagnosis and nontreatment was prevalent.

The Effects Of Two Management Techniques On The Generalization Of A Syntax Structure, Karin Jeanne Goodling

Dissertations and Theses

The effectiveness of any language training program is determined by generalization of the clinically trained behaviors to spontaneous speech. Traditional language programs which employ operant procedures to establish the behavior in the clinic and reinforcement from family, teachers and peers in a variety of settings to obtain generalization, have been successful in establishing the use of grammatical rules in the clinic setting, but reportedly have failed to promote generalization. Recent literature in the areas of semantics and pragmatics has produced a trend toward teaching language in natural contexts. The purpose of this study was to investigate: 1) whether a group …

The Geology And Hydrothermal Alteration Of The Bear Creek Butte Area, Crook County, Central Oregon, Richard Matthew Wilkening

Dissertations and Theses

The Eocene Clarno Formation, the Oligocene John Day Formation and basalts of the High Lava Plains are exposed in the Bear Creek Butte area in Central Oregon. In this area the Clarno Formation can be divided into a lower sequence composed of intermediate lava flows with intercalated mudflows and volcaniclastic sediments and an upper sequence of rhyolite and basalt flows and felsic ruffs. Separating the two units is a well developed saprolite. The change from intermediate to rhyolite-basalt volcanism reflects a change in the tectonic environment of the Cascade volcanic arc from compression to relaxation as subduction of the Farallon …

Manipulation Or Education?: Symbolic Language, Belief System And The Truman Doctrine, John Gunn Tilson

Dissertations and Theses

The question arises in the analysis of foreign policy decision making regarding how consensus or approval by the public is attained for policies. Some authors have suggested that consensus is obtained through the manipulation of opinion by decision makers. One case often cited as an example of manipulation is the 1947 announcement of the Truman Doctrine.

In determining the validity of these arguments a review was conducted of the language of the doctrine and the interpretations of newspaper columnists. In addition, a review of personal documents of the decision makers was conducted to determine their impressions.

The data compiled from …

The Effect Of Salinity On Habitat Selection Of Two Oregon Chiton Species (Katharina Tunicata And Mopalia Hindsii), David Carl Rostal

Dissertations and Theses

Adult specimens of Katharina tunicata (mean weight = 10.23 grams) and Mopalia hindsii (mean weight = 10.90 grams) were tested for osmotic stress tolerance and oxygen consumption rates in a series of salinities (120%, 100%, 80%, 60%, and 40% seawater) at 11°C and 16L:8D photoperiod. K. tunicata and M. hindsii displayed similar trends in percent body weight variation and volume regulatory responses to osmotic stress. However, K. tunicata experienced a significantly higher percent body weight increase than did M. hindsii in response to hypo-osmotic conditions (80%, 60%, and 40% seawater). The mean rates of oxygen consumption per salinity for the …

Humor Creation And Appreciation As An Indicator Of Intercultural Communication Effectiveness: Toward A Theoretical Model, Richard D. Tavano

Dissertations and Theses

A review of the theoretical and empirical literature from the field of humor and from that of intercultural communication showed that no investigations dealt with the possibility that a sense of humor might serve as an indicator of intercultural communication effectiveness. This study was conducted in order to assess that possibility.

This paper has set out to answer the following questions: What cognitive processes are common to a sense of humor and to intercultural communication effectiveness? What does one's ability to create and appreciate humor say about that individual's potential for intercultural communication effectiveness? Through the review of the literature, …

Biostratigraphy Of The Cowlitz Formation In The Upper Nehalem River Basin, Northwest Oregon, Neil B. Shaw

Dissertations and Theses

Examination of stream and roadcut exposures of the Cowlitz Formation allows the selection of measured representative sections, and collection of fossils, from an area roughly defined by the intersection of the boundaries of Clatsop, Columbia, Tillamook and Washington counties in Oregon. The study defines the features of the local environment of deposition, correlates sections to derive a composite columnar section, and develops a checklist of species for both microfossils and megafossils of the Cowlitz Formation.

Hop Agriculture In Oregon: The First Century, Kathleen E. Hudson Cooler

Dissertations and Theses

This thesis was written to document, through both primary and secondary sources, the history of hop growing as it was in Oregon between 1850 and 1950. In those years, hop growing was most often a speculative venture. Growers could be rich one year and bankrupt the next due to the uncertainties of marketing.

Technology Impact Assessment: The Effectiveness Of Advanced Instructional Technology In Remedying Learning Difficulties Of Disadvantaged Youngsters In An Urban Setting, Wossen Encubahre

Dissertations and Theses

Technological advancement has allowed widespread use of computers. Teachers are using computer based instruction in educating talented and disadvantaged youngsters. Unabated by unsettled issues and claims, computers are introduced to cope with declining enrollment and school revenues; pressure to improve student achievement and cut costs. However, some educators fear two possibilities: computer displacement of teachers; and creating a class of technologically disadvantaged students that could result from a growing gap of access to computers. Another factor is the restriction of disadvantaged students to basic skills. While providing opportunities of a wider application to others. The objectives of this research are: …

Analysis Of Problemsolving Groups With Feedback Intervention Using A Systematic Multiple Level Observation Of Groups, Donna Buchanan Schantz

Dissertations and Theses

The purpose of this study was to determine the effects of a feedback cycle on problemsolving groups. A formal method, Systematic Multiple Level Observation of Groups (SYMLOG), was employed for the analysis of behavior in such groups. The system, which codes on multiple levels of communication, served both as a theoretical and an explanatory approach. Problemsolving groups which included a feedback session on group process were compared with problemsolving groups which were not given feedback. The study used primary data from SYMLOG field diagrams to determine whether group movement, leader movement, self-perceptions, and group satisfaction would be affected by feedback …
