The Introduction Of European And Asian Cultural Materials On The Alaskan And Northwest Coasts Before 1800, Herbert Kyle Beals

Dissertations and Theses

This thesis concerns the introduction of exogenous cultural materials among the native inhabitants of the Alaskan and Northwest coasts prior to the and of the 18th century. It is an investigation of the sources of these materials and the manner and chronology of their introduction. The research is based primarily on data drawn from accounts of native life by explorers and fur traders who visited the coasts of northwestern North America in the 18th century. These accounts are supplemented by ethnologic and archaeologic data collected by anthropologists in the 19th and 20th centuries.

Formation And Zonation Of Ferruginous Bauxite Deposits Of The Chapman Quadrangle, Oregon, Richard Charles Marty

Dissertations and Theses

Two major theories have been advanced to account for the scattered distribution of ferruginous bauxite deposits. Original workers proposed that ferruginous bauxite originally developed over all exposed Columbia River Basalt in western Oregon and was subsequently removed by erosion. Studies which followed have suggested that it may be locally favorable conditions, especially of drainage, which are responsible for deposit distribution. Field mapping in the Chapman Quadrangle shows a possible correlation between a series of sheared zones, which may have improved drainage, and the distribution of ferruginous bauxite deposits. Examination of the pisolitic zone ferruginous bauxite of the Chapman Quadrangle failed …

A Study Of The Diagenesis Of The Overburden Between The Badger And School Coal Seams, Dave Johnston Coal Field, Converse County, Wyoming, Rebecca K. Jaffer

Dissertations and Theses

Low pH zones in portions of the overburden at the Dave Johnston Coal Field, Converse County, Wyoming are the subject of this study. The low pH zones are restricted to limonite stained sandstones which grade downdip into normal pH gray sandstones. Changes in color, clay mineralogy, cementation and feldspar surface textures are noted between the two sandstone units. These changes appear to be the result of post depositional alteration that was responsible for oxidation of pyrite and chlorite, dissoluion of calcite, and the etching of feldspar grains. The parameters for the diagenesis fit those of uranium roll front models proposed …

Parameters Of Mental Rehearsal, Timothy K. Kelly

Dissertations and Theses

An extensive review of the literature of the phenomenon of mental rehearsal (MR), or the act of imagining oneself performing a behavior in anticipation of eventually doing so, indicated that MR could facilitate improved performance on varied motor skills. An experiment which drew from previous studies in MR, incorporated suggestions from.the literature, and used a novel measurement task was conducted. The present study compared MR to physical practice (PP), no practice (NP), mental rehearsal/physical practice combined (MR/PP), and interference mental rehearsal (I). Five groups of twenty subjects (N=100) played a hand-held video computer game in a pre- and post-test design. …

Serial Cardiovascular Adaptations During Pregnancy, Mark Vincent Hart

Dissertations and Theses

Maternal cardiovascular adaptations appear to be essential in order to supply extra circulation to both the developing fetus and maternal system during a successful pregnancy. Since inadequate cardiovascular adjustments may produce abortions or maternal morbidity, the characterization of maternal cardiovascular changes during pregnancy and the elaboration of the underlying mechanism for these changes are essential to the understanding of how the heart enlarges during pregnancy and what significance this enlargement might have. To provide needed information regarding this time course and extent of maternal cardiac enlargement and the hormonal and hemodynamic changes which may be responsible for these changes, the …

The Work Values Of Secondary Teachers : A Comparative Study By Teaching Assignment, Charlotte Marie Klampe

Dissertations and Theses

The focus of this study was on the work values of secondary school teachers. Values have been defined in many ways. The common agreement is that values are standards, beliefs, or principles that do guide and direct a person's behavior. The values a teacher holds will influence a student due to the natural role-modeling effect in the classroom. With the advent of career education and exploration of the world of work, the values held toward work become a timely topic. The discussion of values and value clarification in all aspects of a person's life is one that is becoming very …

Institutional Environments As Perceived By The Faculty And Administrators At Six Small Liberal Arts Christian Colleges, Jeffrey Thomas Fouts

Dissertations and Theses

The purpose of this study was to determine if the small liberal arts Christian colleges provide a distinctive environment apart from the traditional classifications of colleges and universities. The environments of the six sample colleges were assessed by administering the Institutional Functioning Inventory (IFI) to faculty and administrators. Statistically significant differences were found among the colleges on eight of the 11 environmental dimensions. However, it was concluded that the colleges constituted a relatively homogeneous group on all dimensions measured except Self-Study and Planning. Total sample means on the 11 scales of the IFI allowed for a generic description of 11 …

The Paleolimnology Of Bull Run Lake: Disruption And Stability In A Natural System, Richard Brian Raymond

Dissertations and Theses

Detailed analysis of the physical, chemical, pollen and diatom stratigraphy of sediment cores from Bull Run Lake, Oregon reveals that the lake has been subject to repeated episodes of disruption by volcanic ash fall, fire and other disturbance over the past 4300 years. With the exception of fire, these disruptions have not resulted in long term changes in the watershed or in the characteristics of Bull Run Lake. A major fire in the watershed about 750 years ago altered the vegetation. Since that time the forest has been returning to its former condition.

A Study Of The Modification Of Teachers' Attitudes Toward The Hearing-Impaired Using Two Different Types Of Treatment Workshops, Anita Bell Mcclain

Dissertations and Theses

This experimental study grew out of the ideas gleaned from a review of literature which indicated that the attitudinal role of the classroom teacher serves as a model for students. A justification of the need to modify behaviors toward the hearing-impaired became apparent. The significance of effective workshop procedures could result in notable implications for school district planning and implementation of an in-service education plan. An experimental study was conducted to determine if teacher attitudes toward the hearing-impaired can be modified using two types of in-service workshops, passive versus active participation. Three groups of randomly selected regular classroom teachers at …

An Investigation Of The Reliability, Subscale Intercorrelations, And Validity Of The Administrator Role Perception Inventory, Anne Skirven Wax

Dissertations and Theses

The purpose of this study was to investigate the reliability, subscale intercorrelations, and validity of the Administrator Role Perception Inventory (ARPI), an instrument developed by the investigator and a co-author in the year preceding the study. The ARPI is a 50 item, Likert-type scale which reflects variables thought to be associated with burn-out: expectation, motivation, accomplishment, psycho-physical state, and relationships. Another variable, previously unresearched, was also included; it is the variable of "time" and reflects a negative time orientation, a longing for the "good old days." The inventory was mailed to all of the 2,113 active members of the Confederation …

A Mechanistic Study Of The Electrochemical Formation Of Cds Cdse Semiconducting Films, Mario Aparicio-Razo

Dissertations and Theses

Cadmium sulfide and cadmium selenide are important materials for applications such as photoconductive cells, photovoltaic cells and other electrooptical devices. Generally, these devices use single crystals. However, reasonable efficiencies have been observed by using polycrystalline films on conducting substrates, which are easier to make and provide considerable savings on materials and energy. Polycrystalline CdS/CdSe films have been made by sputtering and solution spraying, compound evaporation, chemical vapor deposition, and many others. A recent technique involves the electrochemical deposition of CdS and CdSe from nonaqueous solvents. Preparation of these films is based upon the cathodic deposition from a nonaqueous solution of …

An Exploratory Functional-Structural Analysis Of American Urban Traditional And Alternative Secondary Public Schools, Mary Ellen Sweeney

Dissertations and Theses

This study investigates the way traditional and alternative secondary public school organizations are structured to impact youths. Some studies have found that traditional secondary schools utilize inappropriate and outdated organizational elements and arrangements. Alternative schools with different organizational arrangements have been initiated in public school districts to institute school reform measures. The three goals of this study are to: (1) collate a large share of the literature on the function, social context and organizational characteristics of conventional and alternative secondary public school organizations, (2) explicate a theoretical framework or interrelated set of propositions of organizational principles regarding modern organizations, including …

The Health Policy Gap: Income, Health Insurance And Source Of Care Effects On Utilization Of And Access To Dental, Physician And Hospital Services By Oregon Households, Constance Hall Fitzgerald

Dissertations and Theses

This study explores the effects of income, insurance, and source of medical care on access to and utilization of health services. Profiles of dental, physician, and hospital services use are developed for more than 3,500 Oregonians. Low income, lack of health insurance, and/or an inappropriate source of medical care are hypothesized to be barriers to access and utilization. Households which face one or more of these barriers are identified as falling into a "Health Policy Gap." The data for this study were drawn from a 1978 random telephone survey of 1249 Oregon households. The survey was commissioned by the State …

Secondary Stresses In Bowstring Timber Trusses, John F. Bradford

Dissertations and Theses

This study was undertaken in order to determine analytically the magnitude of the secondary (i.e., joint deflection induced) moments in the continuous glued-laminated chords of bowstring timber trusses. Traditionally, these moments have been assumed to be small and therefore neglected. The American Institute of Timber Construction makes no mention of these moments in their recommended design procedure.

Psychometric Properties Of The Group Process Questionnaire, Lucia Igou Eakins

Dissertations and Theses

The Group Process Questionnaire (GPQ), a 55-item rating scale, was developed by Richard Wollert in 1981 to assess perceptions of the frequency of processes occurring in self-help groups (SHGs). The GPQ was first employed by Wollert, Eakins, and Dixon (Note 1) as the primary data collection instrument in an ongoing investigation of urban SHGs. This investigation is one of a small number of empirical studies which have attempted to specify the range of SHG activities. Due to the relatively recent emergence of SHGs as topics of research, and the unique obstacles to research presented by the independent character of these …

A Geophysical Study Of The North Scappoose Creek, Alder Creek, Clatskanie River Lineament, Along The Trend Of The Portland Hills Fault, Columbia County, Oregon, Nina Haas

Dissertations and Theses

The Portland Hills fault forms a strong northwest trending lineament along the east side of the Tualatin Mountains. An en echelon lineament follows North Scappoose Creek, Alder Creek, and the Clatskanie River along the same trend, through Columbia County, Oregon. The possibility that this lineament follows a fault or fault zone was investigated in this study. Geophysical methods were used, with seismic refraction, magnetic and gravity lines run perpendicular to the lineament. The seismic refraction models indicate the near surface basalt is broken in many places, with 15 - 30 meters (50 - 100 feet) vertical displacement, down to the …

The Effect Of Dwarf Mistletoe (Arceuthobium Americanum) Upon A Portion Of The Carbon Budget Of Lodgepole Pine (Pinus Contorta), Nancy Ellen Broshot

Dissertations and Theses

Arceuthobium americanum is a vascular plant which is parasitic upon Pinus contorta var. murrayana. Its documented effects include reductions in host growth, vigor and wood quality. The specific physiological changes that occur in the host are, for the most part, unknown.

In an attempt to understand the manner in which the mistletoe alters its host's carbon budget, a model is proposed which states that the host plant has priorities for carbon allocation. The model proposes that the parasite will access the host's carbon initially in terms of carbon intended for storage, next, in terms of carbon intended for growth, …
