Cylindrical Laser Resonators, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

A general class of cylindrical laser resonators is described in which the radiation propagates partially in the radial direction. There is a strong focusing of energy at the axis of such resonators. The low-loss cavity modes are related to ordinary gaussian beam modes. Two limiting forms are the disk laser and the tube laser, and some applications are considered.

The 1972 Cigarette Tax Referendum: A Mass Communication Campaign, Gwendolyn Moore Danielson

Dissertations and Theses

During the past forty years, Oregon voters have approved only two tax proposals; both taxes on cigarettes. The subject of this study is the campaign carried out by proponents of H.B. 3064 to pass the most recent Oregon tax referendum measure. Central to the questions asked in the investigation of the 1972 cigarette tax campaign was why the outcome of this proposal was successful. The thesis hypothesizes that the critical variable was the involvement of major socio-economic interest groups in formulating and disseminating persuasive campaign messages.

The rationale for entering into such a study was the shortage of information on …

Decay Of Multiple Spin Echoes In Dipolar Solids, C. H. Wang, John D. Ramshaw

Physics Faculty Publications and Presentations

In this paper we derive a general expression describing the evolution of the transverse nuclear-spin magnetization for the Ostroff-Waugh multiple-spin-echo experiment in dipolar solids. Our approach consists of expressing the formula for the magnetization at even echoes in a form resembling an ordinary time-correlation function, and then evaluating this quantity by means of Zwanzig's projection-operator technique. For long times, we show that under certain conditions the echo envelope decays exponentially, in agreement with experiment. A general expression is obtained for the time constant T^* associated with the decay. This result may be used to generate an expansion of 1T …

Continuity Of A Traditional Social Pattern: The "Man-Patron" Relationship In Contemporary Northeast Brazil, Patricia Ellen Thorpe

Dissertations and Theses

Northeast Brazil is a region characterized by economic poverty and human misery. Poor ecological conditions contribute to the nature of the dilemma, but another factor in the apparent cultural stagnation of the Northeast, may be the persistence of values and social practices traditionally aligned with the colonial sugar plantation system. Thus, this thesis represents an examination of the continuity of a given pattern, the man/patron relationship. This pattern is a contemporary parallel to the master/slave relationship which was the key to understanding of the social system of the colonial period. An historical overview reveals the nature of the traditional system, …

Social Desirability And The Interpersonal Check List, Deborah Jean Wheeler

Dissertations and Theses

The purpose of this study is to investigate whether number of responses is related to the social desirability and intensity of the test items. 61 Ss were administered the Interpersonal Check List and the Marlowe Crowne Social Desirability Scale. From the Interpersonal Check List number of responses, average item intensity and average item social desirability were calculated. Average item social desirability was calculated from individual item social desirability values obtained from ratings by another, similar S group. The results showed that number of responses is negatively correlated with average item social desirability and positively correlated with average item intensity, as …

Existence Of The Dielectric Constant In Rigid-Dipole Fluids: The Direct Correlation Function, John D. Ramshaw

Physics Faculty Publications and Presentations

The question of whether the dielectric constant ε exists (is well defined) for a finite fluid system of rigid dipolar molecules is reconsidered and reformulated. It is found that this question can most simply be expressed in terms of the behavior of the position‐ and orientation‐dependent direct correlation function c(r₁,ω₁; r₂, ω₂). It is shown that ε exists if c satisfies the following two conditions: (a) c~–φ/kT for |r₁–r₂|>σ, where φ is the dipole‐dipole potential and σ is a length which is large microscopically but small macroscopically. …

A Gold Dream In The Blue Mountains: A Study Of The Chinese Immigrants In The John Day Area, Oregon, 1870-1910, Chia-Lin Chen

Dissertations and Theses

More than one hundred years have passed since the Chinese laborers first landed in this country in the mid-nineteenth century. Yet their history remains cloudy. This phenomenon is quite understandable if one considers the facts that most of the laborers were illiterate, did not have the ability, and never intended, to speak for themselves. It is true that many scholarly works have been published, but few were written by Chinese historians. As a matter of fact, Chinese scholars are unaware that a small number of their countrymen played a strange, pitiful role in American history. The published works reflect the …

New Method For Generating Density Expansions, John D. Ramshaw

Physics Faculty Publications and Presentations

The calculus of finite differences is used to develop a new method for expressing the thermodynamic limit of a reasonably arbitrary statistical?mechanical average as a power series in the number density ?. The method is simple, straightforward, and purely analytic: it involves no intermediate expansion in powers of the activity and it avoids the use of graph theory. Moreover, the method is developed independently of the prescription for computing the statistical average, a fact which lends to the results an especially wide range of applicability. In particular, these results may be used in classical or quantum statistical mechanics, for intermolecular …

The Use Of Junior Historical Fiction In The Classroom, Darlene Pelinka

Dissertations and Theses

The use of American historical fiction in an eighth grade social studies or language arts class has not been fully explored, so its literary and social science value is questionable. In order to establish its worth and methods for its use, research into desirable 1iterary goals for adolescents, implications and purposes of historical fiction in general and for youth in particular, a bibliography of novels, and an evaluative survey of specific novels written for youth needed to be done.

The research indicates that some critics believe that most junior novels have little to offer youth and that they are poorly …

The Relationship Of Written Expression To Self Concept In Primary Children, Anna Lou Case

Dissertations and Theses

This thesis, the outcome of nearly three years of preparation, including study, development of procedures, trial and observation, was begun in an attempt to answer the following questions: How may original writing among elementary pupils be motivated successfully? Can positive feelings about self be promoted to a measurable degree as a result of emphasizing individual oral and written expression?

Although much thinking and evaluating occurred during the three years, the experimentation and results reported here are limited to the work accomplished and findings obtained during the third year. The twenty-six children involved in this study were third-year elementary pupils, whose …

Johann Adam Moehler: The Method Of Historical Theology, Christina Maria Crose

Dissertations and Theses

This thesis is a study of Johann Adam Moehler's critical theology as an achievement in the nineteenth century's quest for a historical methodology. As the first Catholic theologian to apply a critical-historical analysis to the development of doctrine, Moehler is important as both the theologian and as a German historian.

As the theologian, Moehler's efforts to discover the essential meaning of Christian doctrine led him to conclude that doctrine develops within a human context of experience, namely, the Catholic Church. This development of doctrine is possible given the organic nature of the Christian community and its relationship to the divine. …

An Investigation Of Between-Ear Tympanometry Measures In Normal-Hearing Young Adults, Barry Lynn Kimmel

Dissertations and Theses

In recent years, tympanometry has been used to provide objective and definitive information regarding the status of middle ear conditions and functions. The present standard for tympanometric normalcy is based upon between-subject measures. This standard, however, does not allow precise differentiation between normal and pathological tympanometry curves. A within-subject comparison of right and left ear tympanometry curves of normal-hearing subjects could provide a narrow standard of tympanometric normalcy which would be more useful in differentiating between pathologic and non-pathologic middle ear function. The within-subject relationship between tympanometry curves for right and left ears was investigated by comparing the individual right …

Effects Of Certain Linguistic Parameters Upon The Responses Of Preschool Subjects To Specific Dichotic Listening Tasks, Peggy J. Weber

Dissertations and Theses

Listening, as a communication skill, is an essential factor in the normal language development of the' child. Until recently, however, there has been very little research conducted concerning the linguistic parameters that influence the ability to listen. Thus, this investigation was designed to study the effects of two linguistic parameters, construction and semantic constraints on the verbal responses of preschool children in a dichotic listening task.

Fifteen children, between the ages of 5-3 to 6-8, were presented with four dichotic listening tasks consisting of 80 stimuli, (40 sentences and 40 pseudo-sentences). The children were asked to report the message delivered …

An Investigation Of Temporary Threshold Shift Among Helmeted Motorcycle Riders, Alamander Hicks

Dissertations and Theses

The purpose of the present study involved the investigation of the significance of wind noise as a contributing factor toward temporary threshold shifts among a select sample of motorcycle riders. Five normal-hearing, helmeted, female subjects were administered pure-tone air-conduction hearing tests immediately before and within 2 minutes after exposure to three noise-related aspects of motorcycle riding. The amount of hearing loss present at 3k, 4k and 6k Hz after each 20 minute exposure condition was recorded as the TTS for that subject. The three conditions consisted of motorcycle noise only, wind noise only and motorcycle and wind noise combined. A …

Entropy Reduction Of English Text Using Variable Length Grouping, Vincent Norman Ast Jr.

Dissertations and Theses

It is known that the entropy of English text can be reduced by arranging the text into groups of two or more letters each. The higher the order of the grouping the greater is the entropy reduction. Using this principle in a computer text compressing system brings about difficulties, however, because the number of entries required in the translation table increases exponentially with group size. This experiment examined the possibility of using a translation table containing only selected entries of all group sizes with the expectation of obtaining a substantial entropy reduction with a relatively small table.

An expression was …

Villa St. Rose Group Home Study, William H. Finkle

Dissertations and Theses

There has been a gradual move from the exclusive use of institutions for delinquent adolescents as a treatment resource to a realization that institutions need a variety of treatment methods in order to rehabilitate delinquents and other adolescents with adjustment problems. Villa St. Rose is an example of an institution which has acknowledged the effectiveness of developing a therapeutic milieu based on a professional institutional program supported by community treatment in the form of a group home experience.

The Behavior Of Coalitions As Interorganizational Structures: An Exploratory Study Using A Grounded Theory Approach, Elaine Marie Rothrock

Dissertations and Theses

This study is one of four exploratory studies concerned with coalitions of organizations that are formed to plan and develop social welfare programs within the local community. Although each study was conducted independently, taken together their major purpose was to develop some insights and knowledge into the behavior of organizations and the ways in which they interact as they work together to develop community programs. They are, then, exploratory studies of inter-organizational behavior.

Each of the studies had a different focus. One study attempted to identify the present areas of agreement and disagreement regarding inter-organization behavior by systematically reviewing the …

An Analysis Of Change In Girls Released From Villa Saint Rose, H. Marie Ades

Dissertations and Theses

When juveniles are defined by society as delinquent they are frequently institutionalized. These institutions are referred to as reform schools, correctional institutions or schools, residential care facilities, treatment centers, or variations of the above. They are state sponsored or privately sponsored. Whatever name is on the sign by the front door, each institution is in the business of "people changing."

The excellence of an inanimate product can be measured, weighed, checked, and reproduced; but an altered person is more difficult to measure. If one is in the business of people-changing, it seems important to see if one is in fact …

Diagnostic Congruence: A Study On Presentation Of Clinical Information To Parents And Recall, Miriam Rae Maier

Dissertations and Theses

The present study was an investigation of recall following presentation of diagnostic information. The setting was the Crippled Children's Division of the University of Oregon Medical School.

The purpose of the study was to test the hypothesis that one session conferencing imparting diagnostic information to parents of handicapped children reduces recall. Additionally, it was hypothesized that multi-discipline conferencing is related to greater diagnostic recall than single discipline conferencing. The sample was made up of 20 parent units whose children were evaluated at the Crippled Children's Division for suspected Cerebral Palsy and/or Mental Retardation. There were ten families from the Cerebral …

The Life Cycle Of Lissorchis Heterorchis, Macy And Krygier (1969), Brendan P. H. Onyejekwe

Dissertations and Theses

Many Flumenicola virens (Lea) collected from Crystal Springs Creek and Tualatin River, Portland, Oregon, were found to shed large numbers of a species of microcercous cercariae containing refractile granules. They resembled the cercariae of Triganodistomum mutabile (=Lissorchis mutabile Cort, 1918 as described by Wallace (1939), and subsequent experiments proved that they were the larval stages of what was described by Macy and Krygier (1969), as Lissorchis heterorchis. Encystment of these cercariae was induced experimentally in uninfected adult brown planarians collected partly from Crystal Springs Creek and partly from Carolina Biological Research Station in Gladstone, Portland, Oregon. Adult flukes …
