Explosion Structures In Grande Ronde Basalt Of The Columbia River Basalt Group, Near Troy, Oregon, Leonard Lee Orzol

Dissertations and Theses

Explosion structures occur in flows of Grande Ronde Basalt in the study area near Troy, Oregon. Data from nineteen stratigraphic sites indicate that the maximum number of flows that contain explosion structures at any one site is six. In the informally named Troy flow, explosion structures are widespread.

Each flow that contains explosion structures can be divided into two cooling units. The first cooling units occupy troughs in the pre-eruption topography and are up to 10 meters thick. The second cooling units contain the explosion structures and are up to 100 meters thick. The thickness of flows that contain explosion …

American Foreign Policy: The Utility Of Force As An Influence, Bargaining, Or Coercive Force In The Caribbean Basin, Susan M. Marandas

Dissertations and Theses

Throughout history states have pursued both cooperative and power-oriented strategies. Moralists and realists have long questioned the appropriateness of using force to gain state objectives. Recent analysts have stressed that states have a moral duty to manage international uncertainty in the best interests of their citizens. While this might involve utilizing both power-seeking and order-seeking strategies, it has been suggested that pursuing order-seeking strategies could help alleviate international uncertainty.

An historical survey, as well as recent case studies in Grenada and Nicaragua, indicate that the United States often has relied upon military strategies in the Caribbean Basin. The United States …

German-Czech Conflict In Cisleithania: The Question Of The Ethnographic Partition Of Bohemia, 1848-1919, Nicholas Aldorde

Dissertations and Theses

Bohemia, Moravia and Silesia, the former Crownlands of Austria-Hungary which now make up the western half of Czechoslovakia, had for centuries a population mixture of 40% German, 60% Czech. The national reawakening of the eighteenth and nineteenth centuries pitted the majority Czechs against their German minority master. This, coupled with the social upheavals caused by the industrial revolution, brought Czechs and Germans in Bohemia to center stage in the nationality conflict in the multinational Empire.

The Effects Of A Course In American Jokes On A Class Of Intermediate Level Esl Students, John Randolph Carruthers

Dissertations and Theses

Teachers of English to speakers of other languages have often incorporated humor in the curriculum, yet a recent computer search revealed that there were no empirical studies which have shown that curricular humor enhances English language learning. The three specific questions of the thesis are: does the use of curricular humor 1) improve memory/recall, 2) improve over-all English proficiency, and 3) result in the subjects' having more positive attitudes towards Americans, and if so, does a more positive attitude correlate with improved memory/proficiency?

Segment Congruence Analysis: An Information Theoretic Approach, Jamshid Hosseini-Chaleshtari

Dissertations and Theses

When there are several possible segmentation variables, marketers must investigate the ramifications of their potential interactions. These include their mutual association, the identification of the best (the distinguished) segmentation variable and its predictability by a set of descriptor variables, and the structure of the multivariate system(s) obtained from the segmentation and descriptor variables. This procedure has been defined as segment congruence analysis (SCA). This study utilizes the information theoretic and the log-linear/logit approaches to address a variety of research questions in segment congruence analysis. It is shown that the information theoretic approach expands the scope of SCA and offers some …

The Philosophy Of William James As Related To Charles Renouvier, Henri Bergson, Maurice Blondel And Emile Boutroux, Peggy Lyne Hurtado

Dissertations and Theses

This thesis argues two issues: William James' philosophy was-to a great extent derived from his interaction with the French philosophers, Charles Renouvier, Henri Bergson, Maurice Blondel and Emile Boutroux. Correlative to the fact that these five figures have an intellectual relationship with one another, I also argue that in order to understand James, he must be placed within the context of these relations. These five philosophers, as a group, can be clearly seen and understood in the context of an identifiable movement. Each one was a part of a whole reality with their own slightly different perspectives. However, the context …

Norepinephrine And Temperature Regulation In Goldfish, Lonnie Paul Wollmuth

Dissertations and Theses

Cannulae were implanted into forebrain loci of goldfish (Carassius auratus; 45-90 g) to determine (i) the effects and site of action of intracranial norepinephrine (NE) injections on behavioral thermoregulation and (ii) the mechanism and the types of adrenoreceptors involved in the thermoregulatory effect of NE. After 30 min in a thermal gradient, implanted fish were injected with norepinephrinebitartrate salt (2.5-500 ng NE) in a total volume of 0.2 ul (carrier was 0.7% NaCl). Injections of 5, 10, 25, and 50 ng NE into the anterior aspect of the nucleus preopticus periventricularis (NPP1 Peter and Gill 1975) led to consistent, dose-dependent …

Repetitions In The Speech Of Normal Two Year Old Males, Stephanie Herrick

Dissertations and Theses

Development of fluency has always been an important focus of stuttering research. However, to date there are no standardized norms on the development of fluency. Reliable and valid information regarding the normal development of fluency is necessary in order to deferentially diagnose normal disfluency from incipient stuttering. Establishment of norms for part-word repetitions is especially important since this type of disfluency has traditionally been considered an indicator of early stuttering. The present study sought to contribute to the investigation of the development of fluency by examining the frequency of occurrence of repetitions in 30- to 36-month-old males.

Dissertations and Theses

Purpose. This study was designed to determine the perceptions of the Oregon-certified nurse practitioners (NPs) with respect to their usage, competency, and preparation for selected functions. Clarification of what NP's perceive themselves doing and with what degree of competence could give structure and direction to their preparation. In Oregon, NPs provide specialized primary care in collaboration with physicians and other health care professions and agencies. The performance of an NP may vary according to the specialty, setting, and needs of the consumer. If some functions of the NP could be brought into clearer focus, then not only could benefits come …

The Impact Of Physical Environment On The Social Climate Of Two Jails, James G. Houston

Dissertations and Theses

In recent years there has been a strong movement to replace outdated and inadequate jails throughout the United States. According to the National Sheriff's Association 15.9% of all jails have been under a court order to improve services or conditions at one time or another. In addition, 960 jails of the 3,493 existing jails in the United States were built prior to 1950. This need for new construction or renovation has given birth to a new area of expertise among architects and contractors--jail design and construction. While design and construction techniques have improved, little is known of the effects of …

An Analysis Of A Washington State Policy On The Appraisal Of School Administrators By Certificated Subordinates, Curtis Alan Miller

Dissertations and Theses

The importance of this topic is suggested by research findings that indicate appraisals of principals by teachers yield information to assess and improve the administrative skills of principals. Research questions sought information on activities at the state level which served to promote implementation of the state policy. Other research questions sought information on the extent and impact of local school district policies and practices that were consistent with the state policy. The methodology for the …

Determinants Of The Spatial Distribution Of Peri-Urban To Rural Agriculture In The United States, Ibrahim Amin Abdel-Karim

Dissertations and Theses

Two issues are focal to the subject of the spatial distribution of crops in peri-urban zones. The first deals with developments in the fields of transportation, other technology, urbanization, and other factors which are not only prevalent in developed world economies, but which also are thought to force the cultivation of freshly consumed agricultural commodities away from the immediate vicinity of the market center. The second issue pertains to indirectly consumed crops, which are thought to shun proximity to the market center, where land rents per unit area are characteristically high, even when conditions for productions are ideal. Traditional models …

A Study Of Ability To Choose Appropriate Conflict Behavior Determined By The Relationship Between Locus Of Control And Conflict Behavior Styles, Mary H. Zinkin

Dissertations and Theses

Two major theoretical controversies were addressed in this study: (1) whether conflict behavior can best be explained by personal characteristics or by situational characteristics and (2) whether there is one best way to handle conflict or several effective ways depending on the situation. Specifically, it explored the relationship between locus of control (internal, powerful others, chance) and conflict behavior (nonconfrontation, solution-orientation, control) in situations where choosing each of these strategies was regarded most appropriate. The study gathered data relevant to four questions: (1) Is there a relationship between an individual's conflict behavior style and personal characteristics such as feelings of …

Comparisons Of Total Factor Productivity In The U.S. Electric Industry, Maya Myoga

Dissertations and Theses

Since the onset of the recession in the 1970's, consumers have frequently expressed frustration with what appear to be ever-increasing utility bills, blaming what they perceive as unnecessarily high rates on industry inefficiency. From the industry perspective, inefficiency is not only the problem which has developed since the recession. The more critical issue is the industry's transition from a noncompetitive environment to a competitive one. In the past, the electric utility industry did not have to compete because each utility operated in an exclusive service territory, and each was regulated by the government. However, currently the industry is experiencing increased …

Dissertations and Theses

The purpose of this study was to examine the "learning-to-teach" process in an alternative teacher education program. Three research questions were addressed to probe the "learning-to-teach" process: (1) To what sources do the interns attribute learning and use of specific teaching behaviors and skills? (2) What are the professional concerns of interns, and are there changes in concerns as they progress through the field experience? (3) How do interns assess themselves as they progress through the field experience, and what is the rationale of the assessment? Qualitative research allows the study of subjects in the natural setting, and enables emergent …

The Stochastic Behavior Of Soil Moisture And Its Role In Catchment Response Models, Nangantani Davies Godfrey Mtundu

Dissertations and Theses

The object of current efforts at investigating catchment response is to derive a physically based stochastic model of the watershed. Recent studies have, however, indicated that a limiting factor in deriving such models is the dependence of hydrologic response on initial soil moisture. The dependence affects the distributions and moments of the hydrological processes being investigated. A stochastic model of soil moisture dynamics is developed in the form of a pair of stochastic differential equations (SDE's) of the Ito type. The sources of stochasticity are linked to the random inputs of rainfall and evapotranspiration (ET). One of the SDE's describes …
