The Development And Effects Of An Educational Audiovisual Presentation On Female Masturbation Upon The Attitudes And Masturbatory Behavior Of College Females, Catherine Ann Hogan

Dissertations and Theses

The current study was designed: (1) to develop an educational tool on female masturbation capable of reaching a wide audience of women with accurate and complete information on female masturbation; (2) to provide initial validation for the further educational usefulness of this tool and (3) to assess its potential ability for improving overall sexual functioning in women by possibly altering negative attitudes toward masturbation and/or by dis-inhibiting masturbatory behavior.

A History Of The Portland Waterfront Between Southwest Clay And Washington Streets, Its Land Use And Legal Problems, Jeffrey Gerald Carter

Dissertations and Theses

Between 1845 and 1980 the Portland waterfront between southwest Washington and Clay Streets, east of Front Street, metamorphosed from wilderness to trade center, to highway, to inner-city vacant lot. No place in Portland has more graphically illustrated the rapidly changing forces of the modern age in which the city has grown.

For much of its history this stretch of waterfront was mired in law suits. The struggles centered on public versus private ownership. Originally dedicated as public property, but left unimproved by the city, the waterfront was usurped by private investors. Eventually, private owners allowed their property to decay prompting …

The Influence Of Halloysite Content On The Shear Strength Of Kaolinite, Reka Katalin Gabor

Dissertations and Theses

The objective of this thesis is to determine the relative shear strengths of halloysite, kaolinite, synthetic mixtures, and local soils, to investigate the influence of halloysite content on the shear strength of kaolinite, and to explore the possibility that the strength properties of soil clays might be controlled by the relative content of their component minerals.

Geology Of A Volcanic Complex On The South Flank Of Mount Jefferson, Oregon, Brian Lee Gannon

Dissertations and Theses

The volcanic stratigraphy and petrography is described for a 46 km² area on the southern flank of Mount Jefferson in the north-central part of the Oregon High Cascades. Here, volcanic processes have been active throughout Quaternary time, resulting in complex stratigraphic relationships. In addition, three formerly recognized glaciations and a two-phase period of neoglaciation have eroded the terrain, depositing tills in contact or interstratified with the volcanic units. Collectively, these processes and the resulting deposits are characteristic of High Cascades development.

The Bungalow Aesthetic: The Social Implications Of A Nationwide Phenomenon Viewed From The Perspective Of A Small Town, Janice Williams Rutherford

Dissertations and Theses

During the first two decades of the twentieth century, a new aesthetic in the domestic architecture of middle-class America emerged. A new style of house, the bungalow, was introduced soon after the turn of the century, and within a very few years, became the most popular building style among Americans who were buying moderately-priced homes. The bungalow was a low, horizontal style of house with deep overhanging eaves and large porches, usually built of natural, textured materials. Its floor plan was notable for opening interior space. The research problem addressed in this study was to determine what factors popularized the …

Following The Drum: British Women In The Peninsular War, Sheila Simonson

Dissertations and Theses

This thesis examines the lives of British women, soldiers' and officers' wives, for the most part, who followed the British army on campaign in Portugal, Spain, and southern France during the Peninsular War (1808-1814). Because most of the women were of the working class, their major roles, as wives, mothers, widows, workers, and criminals, have been contrasted with those roles as defined in British working-class culture.

No direct female sources exist for this war. Information was therefore gathered from male diarists, letter writers and memoirists of the period, using modern research into working-class behavior in the early industrial period as …

Isolation And Characterization Of Frullanolide From Frullania Franciscana (Howe), Marshall Stuart Sass

Dissertations and Theses

Investigation of the ether extract of the liverwort Frullania franciscana (Howe) resulted in the isolation of the sesquiterpene lactone frullanolide. The separation techniques of thin-layer chromatography, dry column chromatography, and liquid column chromatography were evaluated. Only liquid column chromatography was found useful. Fractions from alumina liquid column separations had infrared spectra which resembled the published spectrum of frullanolide. The identity of the compound obtained from F. franciscana (Howe) was established after extensive purification by comparison of its infrared and nuclear magnetic resonance spectra with published spectra of frullanolide.

The Structure, Geologic Evolution And Regional Significance Of The Bethel Creek-North Fork Area, Coos And Curry Counties, Oregon, Carl Fredrick Gullixson

Dissertations and Theses

The original purpose of this study was a detailed structural analysis of the Jurassic Otter Point Formation in order to determine if the Canyonville Fault Zone, which forms the northern boundary of the Klamath Mountains in the Riddle - Canyonville area (Benson and Perttu, 1980), extends westward to the coast and, if possible, to characterize the structure of the Otter Point Formation. Further, a detailed examination of the structural and stratigraphic relationships between the Otter Point Formation and the Eocene Roseburg and Lookingglass Formations was to be performed in an attempt to determine the tectonic history of the area.

A Stratigraphic And Geochemical Investigation Of Ferruginous Bauxite Deposits In The Salem Hills, Marion County, Oregon, Charles William Hoffman

Dissertations and Theses

Pacific Northwest ferruginous bauxite deposits have formed in four main areas of northwestern Oregon and southwestern Washington by laterization of flows of the Columbia River Basalt Group (CRBG). The deposits, averaging 36.3% Al₂O₃ , 31.8% Fe₂O₃ , and 5.9% Sio₂, generally occur near the surface of hilltops in gently rolling areas. Two very different views have been advanced regarding the setting in which the deposits have formed. The first hypothesis calls for a blanket-type laterization by erosion of much of the original deposit upon uplift and dissection of the area.

The first time samples included 13 provider types: hospital doctors, nurses, and nurses aides; in-home nurses and aides; nursing home nurses and aides; mental health practitioners; and income, nutrition, transportation, housing, and interaction personnel. The Encounter Sample included: in-home nurses and aides, …

A Study Of Leslie Model Under Stochastic Environments, Kamran Shaukat

Dissertations and Theses

The prediction and analysis of changes in the numbers of biological populations rest on mathematical formulations of demographic events (births and deaths) classified by the age of individuals. The development of demographic theory when birth and death rates vary statistically over time is the central theme of this work. A study of the standard Leslie model for the demographic dynamics of populations in variable environments is made. At each time interval a Leslie matrix of survival rates and fertilities of a population is chosen according to a Markov process and the population numbers in different age classes are computed. Analytical …

An Analysis Of Environmental, Social And Personal Dimensions And Their Relationship To Psychological Well-Being In Late Life, Renee Tissue

Dissertations and Theses

This dissertation focused on the relationship between psychological well-being and life situations of older persons. Specifically, this study examined whether life situations were different for persons whose Life Satisfaction Index scores changed over a two-year period compared to those whose scores were stable. The sample included 215 older persons living in reduced circumstances. These persons were interviewed on three occasions separated by one-year intervals. Pearson correlations, analysis of variance, and multiple regression procedures were employed to test five hypotheses. Fourteen case studies were selected to illustrate statistical findings. When the dissertation data were analyzed for each occasion separately, findings from …

Physical Effects Of 3-Phenylindole On Ion Transport Across Bilayer Lipid Membranes, Barbara A. Sinha

Dissertations and Theses

The compound 3-phenylindole (3PI) is a particularly active antimicrobial which interacts with phospholipids in fungal mycelia membranes, and which strongly inhibits the uptake of phosphate into fungal mycelia. The physical effects of 3PI on ion transport across bilayer lipid membranes composed of phosphatidylcholine/cholesterol have been investigated using three lipophilic ions and one ion/carrier complex. It was found that 3PI increased the electrical conductivity induced by the lipophilic cation (tetraphenylarsonium) and by the positively charged complex (nonactin-K('+)) by several orders of magnitude whereas 3PI decreased the conductivity induced by the two lipophilic anions (tetraphenylborate, dipicrylamine) by a factor of less than …

Coping With Stress Following A Natural Disaster: The Volcanic Eruption Of Mt. St. Helens, Shirley Ann Murphy

Dissertations and Theses

This study focuses on the coping responses of the bereaved immediate family and close friends of persons who died as a result of the volcanic eruption of Mt. St. Helens in southwestern Washington on May 18, 1980. Three major research questions were addressed: Is there a relationship between illness and three life events: presumed death of a close relative or friend, confirmed death of a close relative or friend, and loss of one's permanent of recreational residence? Do self-efficacy and social supports act as intervening variables to buffer the negative effects of stress on one's health when coping with loss? …

Preliminary Inventory Of Lifeline Systems And Evaluation Of Seismic Hazards In Reno And Sparks, Nevada, Barbara Priest

Dissertations and Theses

The Reno-Sparks community is in a seismically hazardous area. Recent research indicates that a Richter 7.0 or greater magnitude earthquake could affect the area. Many of the emergency and essential facilities are situated in dangerous geological locations and are housed in outdated structures which could be severely damaged in the event of a major earthquake. Detailed site evaluations need to be made with respect to location of new structures and of existing building safety. The 1979 Unified Building Code seismic provisions should be adopted without exception; Nevada Revised Statute 278 .160 needs to be revised to require a seismic safety …

Fortel, A Telecommunications Forecasting System, James Leslie Black

Dissertations and Theses

The telecommunications industry is undergoing a metamorphic change. New technologies have made possible a vast panorama of new services. Electronic newspapers, videotelephones, and computer-mediated conferences are but a few of the possibilities. In contrast to technology, most of the other factors affecting the industry (and its infrastructure) have not changed. Government regulations, for example, are based on the 1934 Communications Act. These factors (e.g., consumer behavior, corporate philosophies, energy, and competition) are beginning to change. The Congress is considering a rewrite of the 1934 Communications Act. Competition has become a dominant factor (note that the industry by and large has …

Approximate Reasoning, Logics For Self-Reference, And The Use Of Nonclassical Logics In Systems Modeling, Daniel Guy Schwartz

Dissertations and Theses

This work advances the use of nonclassical logics for developing qualitative models of real-world systems. Abstract mathematics is "qualitative" inasmuch as it relegates numerical considerations to the background and focuses explicitly on topological, algebraic, logical, or other types of conceptual forms. Mathematical logic, the present topic, serves to explicate alternative modes of reasoning for use in general research design and in model construction. The central thesis is that the theory of formal logical systems, and particularly, of logical systems based on nonclassical modes of reasoning, offers important new techniques for developing qualitative models of real-world systems. This thesis is supported …

Geophysical And Geochemical Analyses Of Selected Miocene Coastal Basalt Features, Clatsop County, Oregon, Virginia Josette Pfaff

Dissertations and Theses

The proximity of Miocene Columbia River basalts to the "locally-erupted" coastal Miocene basalts in northwestern Oregon, and the compelling similarities between the two groups, suggest that the coastal basalts, rather than being locally erupted, may be the westward extension of plateau basalts derived from eastern Oregon and Washington.

The local-origin hypothesis is based largely on the interpretation of coastal dikes and sills as representing vent areas; however, a complex mechanism, as yet unsatisfactorily defined, would be required to cause the eruption of virtually identical magmas simultaneously from source areas 500 km apart.

This study, therefore, has investigated the coastal basalt …

Electrostatic Tem Studies Of Magnetic Domains In Thin Iron Films, Hideaki Karamon

Dissertations and Theses

An electron microscope with electrostatic lenses was used for high resolution studies of magnetic domains in thin iron films.

Observation methods used to determine the directions of local magnetization in iron thin films were the Lorentz method and the Foucault method.

We studied how Bloch line-crosstie pairs and crosstie main walls behave in applied, in-plane magnetic fields. We found that crosstie main walls remain unchanged until crosstie density goes nearly to zero when the field is applied perpendicular to the main wall. A twisted type of domain appears where crossties disappear.

A Cross-Cultural Study Of Role Behaviors Pertaining To The Roles Of Student And Professor, Kathryne Jeanne Nadal

Dissertations and Theses

Communication theory involving the role concept has shown that role expectations and differing evaluations of role behavior can lead to communication breakdowns between persons. Literature pertaining to relations between professors and international students indicates the presence of unfulfilled expectations between them as to how they perform their respective roles. It was therefore hypothesized that some difficulties international students face in the academic world may be due to factors such as differing role expectations. As the literature provided no methodologically based cross-cultural research in this area, the researcher undertook to discover if professors and students evaluate the roles of student and …

An Analysis Of Gravity Surveys In The Portland Basin, Oregon, Janice C. Perttu

Dissertations and Theses

The geologic setting of the Portland Basin is ideal for gravity surveys because of the large density contrasts between geologic units. The Portland Basin consists of a north-northwest-trending syncline in the Columbia River basalt overlain by Pliocene to Recent alluvium. This study was undertaken to define structures in the Portland Basin which are obscured by the alluvium.

An areal gravity survey of the Portland Basin covering approximately 450 square kilometers was conducted for this study.

Effective Force Constant Ratios: Iron In Iridium And Rhodium, Dennis Munsterman

Dissertations and Theses

Classical methods of analyzing heat capacity data for the characteristic moments of the frequency distribution are applied to iridium and rhodium. Impurity moments are determined from high and low temperature f values. These moments are combined by modern theory to estimate the magnitude of the host-host to host-impurity force constant ratio. Ratios of the various host moments are also examined.

Geology Of The Southcentral Margin Of The Tillamook Highlands; Southwest Quarter Of The Enright Quadrangle, Tillamook County, Oregon, Kenneth Allan Cameron

Dissertations and Theses

The Tillamook Highlands is a largely unmapped volcanic pile located in the north end of the Coast Range of Oregon. The 36 square miles of T. 1 N., R. 8 W., on the southcentral margin of the Highlands, was chosen for detailed study.

The study area is composed of Eocene age sedimentary and volcanic units which were deposited in a filling basin. The lowest units were deposited in moderate to deep marine waters; the uppermost were deposited subaerially.

The Structure And Stratigraphy Of The Columbia River Basalt In The Chehalem Mountains, Oregon, Abdul-Rahman Mohammed Al-Eisa

Dissertations and Theses

The Chehalem Mountains area, encompassing 70 square kilometers, is at the western extent of the Columbia River Basalt Group as mapped in western Oregon. The flows in the study area were identified as belonging to subdivisions of the Columbia River Basalt Group on the basis of physical characteristics and trace element geochemistry. The basalt flows are poorly exposed in the area and weathering is deep and extensive where the flows have been exposed. Where erosion has exposed the underlying marine sedimentary rocks, the basalt has failed in landslides.

Stratigraphy And Sedimentation Of The Spencer Formation In Yamhill And Washington Counties, Oregon, Fathi Ayoub Al-Azzaby

Dissertations and Theses

The Spencer Formation in Yamhill and Washington Counties, Oregon, is exposed in a narrow belt 27 km long, from 1/4 to 3 km wide and with a maximum thickness of about 400 m. The formation is composed entirely of sandstone with interbedded thin layers of mudstone in the uppermost member. The sedimentary structure and paleoecology indicate a shallow marine depositional environment. The upper member of the Spencer Formation contains more quartz, plagioclase, and hornblende than does the lower member, but K-feldspar is less than that of the lower member. Shallower water conditions for the deposition of the upper member are …
