A Critical Study Of Communications In Land Use Hearings, Douglas J. Warren

Dissertations and Theses

This study addresses a major theoretical issue posed in the literature: can alienation in modern urban society be conceptualized in terms of the communicative competence of speakers taking part in social interaction. Specifically, this study explores the relationship between communicative competence and two observable indications of success in land use hearings: 1) ability to influence the final decision of the Variance Committee and 2) expression of feelings of dissatisfaction with the hearings process, as expressed by the participants. On a broader scale, the study tests Jurgen Habermas's classification of speech acts and the notion that public hearings are a free …

Occupational Patterns Of Three Generations Of Taishan Chinese : A Reconsideration Of Middleman Minority Theory, Wei Wei Lou

Dissertations and Theses

Middleman minority theory explains why certain minorities in America have made impressive socioeconomic achievements. It is found that their occupational patterns play an important role in their socioeconomic success. Middleman minorities usually concentrate in certain occupations and dominate these occupations. The term "middleman" indicates that such ethnic minorities are functioning as middleman between lower and upper class, customer and producer in the host society.

The three preconditions through which middleman minorities get into these occupations are cultural, contextual and situational variables.

The cultural variables concern mainly the homeland of the minorities, the value system of their native culture, and the …

Voltage Controlled Resistance Model For Mos Transistors, Joey Zong-Yi Jia

Dissertations and Theses

The voltage controlled resistance model is developed for a reliable MOS transistor resistance mapping. The model includes both system and local parameters, and incorporates the effect of rise and fall time variations on the gate delay. MOS transistor resistance mapping is applied in logic simulation and timing verification. Also, it can be used in automatic transistor sizing and critical path analysis.

Rock Slope Stability Studies In Siskiyou National Forest, Greg Visconty

Dissertations and Theses

The line mapping method of Piteau and Martin (1977) was tested on two different rock type road cuts in the Siskiyou National Forest, and was found to be an efficient means of collecting geological data for rock slope stability analysis. The unbiased approach of this method calls for close scrutiny of the outcrops in question, covering more ground than other methods in less time. In turn, this close attention to every crack in the outcrop reveals more about the stability of the slope, and can reveal hidden hazards of rock fall.

The supportive systems for analyzing the data - stereonets …

Hyperbolic Soil Parameters For Granular Soils Derived From Pressuremeter Tests For Finite Element Programs, Dieter Neumann

Dissertations and Theses

In the discipline of geotechnical Engineering the majority of finite element program users is familiar with the hyperbolic soil model. The input parameters are commonly obtained from a series of triaxial tests. For cohesionless soils however, today's sampling techniques fail to provide undisturbed soil specimen. Furthermore, routine triaxial tests can not be carried out on soils with grains exceeding 10 - 15 mm in size.

Initial developments towards a link between high quality pressuremeter tests and the hyperbolic finite parameters element input are presented. Theoretical and empirical approaches are used to determine the entire set of and from pressuremeter tests. …

Development Of A Parametric Analysis Microcomputer Model For Evaluating The Thermodynamic Performance Of A Reciprocating Brayton Cycle Engine, Thomas Joseph White

Dissertations and Theses

In this thesis, applicable data from research on IC engines have been adapted to PACE engine designs. Data from studies on heat transfer, friction, and pressure losses, in particular, have been used. Certain parameters which define operation and design characteristics appear to influence PACE engine performance very strongly. Some of the more critical parameters, notably friction and heat transfer coefficients, must be determined experimentally if accurate model results are to be expected. Pressure ratio, compressor RPM, and maximum combustor temperature, the independent operating parameters, also have a dramatic effect on engine performance. Other design or operating characteristics and working fluid …

The Differential Role Of The Ssi With Normal Preschool Children, Caroline Joy Semler

Dissertations and Theses

The onset of stuttering usually occurs between two and six years which is the same time most children exhibit normal disfluencies often making it difficult to differentiate between normally disfluent children and incipient stutterers. Clinicians need information on the types and frequencies of disfluencies exhibited by normal preschool children in order to determine if a child is more likely to be an incipient stutterer or normally disfluent child. Some clinicians feel uncomfortable relying on past literature since there is a limited amount of information available and the studies have shown a considerable amount of variability in the types and frequencies …

The Effect Of Cold Acclimation On The Temperature Preference Of The Goldfish, Carassius Auratus, And The Brown Bullhead, Ictalurus Nebulosus, Alfred Lord

Dissertations and Theses

Two species of fish, Carassius auratus and Ictalurus nebulosus, were subjected to cold acclimation regimes. Acclimation temperatures were slowly lowered to 3°C, then held for a period of time. At various times during this regime, fish were taken out and allowed to spend time in a temperature gradient to determine their preferred temperatures. Carassius were left in the gradient just long enough to determine a measure of the acute temperature preference, while Ictalurus were left in the temperature gradient for longer periods of time to observe any changes that might occur as the fish adjusted to selected temperatures. In …

The Effects Of Test Result And Diagnosticity On Physicians’ Revisions Of Probability Of Disease In Medical Diagnosis, Ann Elizabeth Sinclair

Dissertations and Theses

This study examined the effects of sensitivity, specificity and result of diagnostic tests on the uses which physicians make of those results. These were compared with the Bayesian model of probability adjustment, which is generally accepted for medical diagnosis. Ninety six active members of the Oregon Academy of Family Physicians were interviewed by telephone, using a case scenario describing a patient with a newly discovered breast lump. Subjects estimated prior probability of malignancy, based on history and physical findings, and then estimated posterior probability following results of a mammogram. Mammograms varied by result (positive or negative) and by high and …

The Influence Of Work Station Architecture On Work Perceptions And Work Behavior, Connie L. True

Dissertations and Theses

A field study was conducted to find whether open office architecture is related to employees' perceptions of their jobs and their work groups, and to their behavior in and around their work stations. Fifty-two employees in the administrative division of a large manufacturing operation volunteered to participate by answering a questionnaire and allowing their work stations to be analyzed for levels of visual access and visual exposure, the two independent variables. Access and exposure, at first theorized to be independent and interacting functions, were found to be too highly correlated in this open office setting to test as originally planned. …

Classifying Oregon Lake-Watershed Ecosystems For Regional Water Resources Assessment, Randall Alan Jones

Dissertations and Theses

Natural lake-watershed ecosystems in Oregon compose a diverse and valuable assemblage of land and water resources. With an increasing demand on lakes for recreation, water supplies, and aesthetic values and an increase in available data on Oregon lake systems, there is a need for applicable and timely scientific water management information about lake conditions statewide. This thesis is an attempt to summarize some of the data collected on natural Oregon lake-watershed ecosystems.

The purpose of the thesis is to identify the most typical natural systems out of an initial data base of twenty-four variables, measured over ninety-eight lake-watershed ecosystems. The …

Disfluencies In Normal Three-Year-Old And Five-Year-Old Male Children, Pamela Paguia Christianson

Dissertations and Theses

The purpose of this study was to compare the frequency of specific disfluencies in 3 year old and 5 year old normal male children in terms of part-word repetitions, word repetitions, phrase repetitions, interjections, revision-incomplete phrases, disrhythmic phonations and tense pauses. The disfluencies were observed while each child spontaneously interacted with an investigator in a clinical room. Two questions were addressed:

1. Do three-year-old male children exhibit a higher overall frequency of disfluencies than five-year-old male children?
2. Do three-year-old male children exhibit a greater frequency of certain disfluencies than five-year old male children?

Decrease In Selected Temperature After Intracranial Dopamine Injections In Goldfish, Hercules Theodore Panayiotides-Djaferis

Dissertations and Theses

Goldfish (Carassius auratus) (40-80g) were injected with dopamine into the forebrain to study the possible involvement of this amine in central temperature regulation in these fish. Dopamine caused a decrease in selected temperature after injection into the rostral nucleus preopticus periventricularis (NPP). This effect was dependent on the dose of dopamine administered. Doses of 25, 50, 100 and 250 ng were used, injected in a volume of 0.2μ1. Injections in regions adjacent to the NPP elicited hypothermic effects only at the higher dosages. These effects were not consistent. Injections in caudal regions of the NPP elicited no effect. …

Geomorphic Character, Age And Distribution Of Rock Glaciers In The Olympic Mountains, Washington, Steven Paul Welter

Dissertations and Theses

Rock glaciers are tongue-shaped or lobate masses of rock debris which occur below cliffs and talus in many alpine regions. They are best developed in continental alpine climates where it is cold enough to preserve a core or matrix of ice within the rock mass but insufficiently snowy to produce true glaciers. Previous reports have identified and briefly described several rock glaciers in the Olympic Mountains, Washington, but no detailed integrative study has been made regarding the geomorphic character, age, and distribution of these features.

The purpose of this study is two-fold. First, surface sediment fabric analysis and relative and …

Friendship Between Women: The Influence Of Incest, Laurie Lockert

Dissertations and Theses

This study focused on the mother/daughter relationship in father/daughter incest and how that relationship influences women's friendships with other women. Many researchers have concluded that females who were sexually abused by male authority figures, i.e., father, step-father, grandfather, older brother, minister, babysitter, will have impaired relationships with men. Clinicians surmise that the enormous betrayal of trust involved in the incest leads the child to generalize from her experience with one male to all males. Victims express feelings of distrust, fear of intimacy, and fear of personal expression in all male/female relationships. Studies suggest that in families where father/daughter incest has …

Hugo Grotius And The Liberal Tradition, Karen Diane Csajko

Dissertations and Theses

One approach in contemporary international relations theory is the moralist position. Most moralists argue that obligations which an individual has toward the state and toward persons qua fellow citizens should not override the obligations which every individual has toward other persons qua members of humanity. Essential to a moralist approach is the idea that every individual shares some feature, such as rights, which is universal to all men and incontrovertible by any body. Many moralists base their theory upon the thought of Hugo Grotius, equating Grotius's thought with their own moralist approach.

This thesis argues that Grotius does not present …

The Effect Of Body Temperature On Arteriovenous Oxygen Difference During Rest And Activity In The Toad, Bufo Marinus, Wayne Bryant Palioca

Dissertations and Theses

The relative contribution of arteriovenous oxygen (A-V O₂) difference to thermally-induced and activity-induced changes in metabolic rate (VO₂) were delineated in the toad, B. marinus. In conjunction, the influence of rest and activity, temperature, and removal of the pericardial sac on separation efficiency (Es) in the anuran ventricle was determined by direct measurement of arterial and venous percent oxygen saturation (% saturation), using a microsampling technique.

El Sindicato De Las Costureras 19 De Septiembre: The Impact Of The 1985 Mexico City Earthquake On Social Process, Margaret Mccrea

Dissertations and Theses

The paper traces out the relationships between three sets of actors--workers, factory owners, and government--before, during and after the 1985 Mexico City earthquake, and places those relationships in the broader context of Mexico's political and economic development, as well as the spatial structure of Mexico City and the garment district. The paper concludes that although victims respond to the crisis by attempting to restore and repair previous social and physical conditions, as social theory predicts, disasters have different effects on different classes of people, who respond according to their needs, vulnerabilities, perceptions, values, and their socially prescribed powers. Where there …

A Comparison Of The Expressive Speech Of Profoundly Hearing-Impaired Children : "Hearing Aids On" Versus "Hearing Aids Off", James Allen Henry

Dissertations and Theses

This investigation was conducted to determine whether the removal of hearing aids from these children for eighteen hours (+ 1/2 hour and including sleep time) would result in reduced speech intelligibility as perceived by a panel of listening judges who were unfamiliar with the speech of the deaf.

Gun Running In Arabia: The Introduction Of Modern Arms To The Peninsula, 1880-1914, James W. Fiscus

Dissertations and Theses

Modern breech-loading rifles flooded into Arabia and the region around the Persian Gulf between 1880 and World War I. This work examines in detail, and analyzes, the introduction of modern arms to Arabia, the origin of those arms, the trade patterns by which they were moved, and the international and local political factors that affected the trade. The international arms trade was driven by three major factors. First, the rapid technological development of small arms in the nineteenth century fed the market, resulting in the availability of hundreds of thousands of obsolete military rifles for resale. Each time new rifles …

A Finite Difference Soil-Structure Interaction Study Of A Section Of The Bonneville Navigation Lock Buttress Diaphragm Wall Utilizing Pressuremeter Test Results, Thomas C. Mccormack

Dissertations and Theses

The P-y curve, used in current practice as an efficient Iine-load vs. soil displacement model for input into the finite difference method of laterally loaded pile analysis, is extended in this study for use with cohesionless soils in diaphragm wall analysis on the Personal Computer with the BMCOL7 program. An analogous W-y curve is proposed, an elastic-plastic model with line-load limits developed from classical earth-pressure theories.

A new formula for predicting a horizontal wall modulus for cohesionless soils from the pressuremeter modulus is developed for use in predicting the displacements on the W-y curves. The resulting modulus values are shown …

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 …
