Field Solutions For Bidirectional High-Gain Laser Amplifiers And Oscillators, Lee W. Casperson, Mohammad Azadeh

Electrical and Computer Engineering Faculty Publications and Presentations

General analytical solutions are obtained for the amplitude, phase, and intensity of the electromagnetic waves in bidirectional homogeneously broadened high-gain laser amplifiers and oscillators. These solutions are important as increasingly high-gain lasers are being employed in practical systems. Expressions are derived relating the output power to the input, including the effects of arbitrary mirror reflectivities and frequency detunings from the line center. For negligible reflectivities, these regenerative amplifier results reduce to earlier expressions for single-pass high-gain amplifiers. Multivalued outputs also occur, and in the limit of low gain per pass the results are consistent with earlier studies of single-frequency laser …

The Relative Influence Of Internal Resources, External Resources, And Social Support On Parenting Stress, Angela Cecelia Rodger

Dissertations and Theses

This study examined the relationship of three different kinds of resources important to parenting to the degree of stress experienced by 58 mothers of small children who completed a questionnaire distributed through kindergarten classes in three public schools, and through three Head Start centers. Parenting sense of competence and internal working model of caregiving were examined as internal resources. Income level and stability and neighborhood characteristics were examined as external resources, and perceived available social support, which is both internal and external, was also examined. Interrelationships between the resources were predicted, as well as the unique contribution of each type …

Rudolf Steiner's Theory Of Foreign Language Learning, Michaela Wolf Hashitani

Dissertations and Theses

Rudolf Steiner is best known as the founder of the philosophical movement Anthroposophie and as the ideological father of Waldorf schools. The Waldorf school program follows Steiner's education principles in that it teaches children to explore their world with all senses. The goal of Waldorf education is to help children develop their soul and spirit in order to become a conscious, mature adult. Waldorf schools introduce two foreign languages at grade one in order to raise world-awareness in children and young adults.

This study reviews Steiner's biographic background until the opening of the first Waldorf school. It highlights Steiner's spiritual …

Training For Volunteer Teachers In Church-Affiliated English Language Mission Programs, Janet Noreen Blackwood

Dissertations and Theses

There is currently a debate among language educators regarding the training and certification of EFL teachers. Largely ignored in this debate are short-term volunteer teachers in church-affiliated English language mission programs. These teachers fall somewhere on the continuum between untrained language teachers and trained professional language educators. The current study took place in response to the lack of research information available on this aspect of ESL/EFL teacher education.

This study focused on the training that is provided to volunteer ESL/EFL teachers affiliated with the Seventh-day Adventist (SDA) denomination. The four research questions sought to determine how the content and procedures …

Returning Women's Workshop And Retention Of Returning Women Students, Kimberly E. Lamb

Dissertations and Theses

This thesis investigates the retention of returning adult women students by examining: 1) demographic and motivational backgrounds of women who attend a university Returning Women's Workshop and women who do not; 2) retention, bonding, and support measures for the two groups of women; 3) student evaluations of the various Workshop components. The thesis also describes the history of the Workshop and the Women's Study Program.

A telephone survey was conducted of women who either participated in the Returning Women's Workshop or attended the University during the same selected years. All the women surveyed were over the age of 24 and …

Illegal Drug Use During Pregnancy: The Effects Of Defendant Race And Type Of Defense On Juror Judgments Of Guilt, Anita Rotondo

Dissertations and Theses

Since the early 1980s fetal harm "caused" by women's illegal drug use during pregnancy has garnered public attention and legal scrutiny. Motivated by concerns over fetal health, the cost of caring for drug-addicted infants, and public support for get tough on crime policies, various states have employed statutes on child abuse, neglect or endangerment, delivering a controlled substance to a minor and contributing to the delinquency of a minor to criminally inculpate maternal drug users.

Utilizing a written hypothetical trial summary in which a woman was charged with child abuse for using cocaine while pregnant, this research explored the effects …

Morphology, Eruption Rates, And Rheology Of Lava Domes: Insights From Laboratory Models, Jonathan H. Fink, Ross W. Griffiths

Geology Faculty Publications and Presentations

The growth of lava domes can be either quiescent or violent, with transitions between styles of behavior commonly occurring with little warning. Here we propose that the behavior depends on the eruption rate, the magma rheology, and the thickness ofthe cooling surface. We present a model, based on laboratory simulations, field measurements, and photographic analysis, that relates the morphology and texture of a dome to the thickness of its cooled carapace, and thence to eruption conditions. A sequence of four main types of dome (spiny, lobate, platy, and axisymmetric) is identified in laboratory analog experiments with a Bingham plastic. These …

La Pine North: Two Futures, Deborah A. Howe, William A. Rabiega

Center for Urban Studies Publications and Reports

This paper provides a vision of how accommodating such high growth may affect one rural residential area of the county, La Pine North. It will first draw a profile of La Pine North as it exists currently. Then, two possible futures for that space and its residents will be depicted. These futures represent the minimal and the most radical responses to the present and intensifying problem of nitrate/nitrogen pollution of ground water in the area. The "Restricted Growth" scenario assumes that the only response to the pollution problem will be the requirement of sand filter septic systems for replacement and …

An Evaluation Of A Staff Mentor Program For At-Risk Students In An Oregon High School: Cake (Caring About Kids Effectively), Gail Lenore Hayes

Dissertations and Theses

This study examined the effect of a staff-mentoring program with students identified as at-risk of becoming early leavers. This mentoring program, Caring About Kids Effectively (CAKE), was implemented at a suburban secondary school in Oregon serving grades 9 through 12.

The study of the CAKE program had four research components: (a) indicators of school success (GPA, attendance, and attitudes toward school) were compared between at-risk students and those not at-risk; (b) indicators of school success were analyzed over the time at-risk students were mentored to find any significant change; (c) indicators of school success and enrollment status at graduation was …

The Effect Of Diastema Closure On The Remediation Of Lateral /S/: A Case Study, Reta Price

Dissertations and Theses

An important morphological-marker and one of the most frequently occurring speech sounds in English, the /s/ phoneme is also one of the sounds most often in need of remediation. Often, air emission during /s/ production, a particularly stubborn, often residual production error, is not remediated through traditional treatment methods, and yet the negative effect /s/ distortions have on listeners has been well-documented.

The subject of this investigation was a forty-eightyear-old male who received treatment for a lateralized /s/ during grade-school. It was hypothesized that his exerting high anterior pressure to prevent air from escaping from a diastema between his two …

Ecology, Wilderness Selection, And The Salmonhuckleberry Roadless Area, Jason Scot Barker

Dissertations and Theses

In the 1970s, the Forest Service used ecology in the process that led to the SalmonHuckleberry roadless area in the Mount Hood National Forest becoming a Congressionally designated Wilderness in 1984. This case study of the history of SalmonHuckleberry roadless area confirms the criticism made by environmentalists that noncommercial forest values have received much less priority than commercial uses in forest planning during the late 1960s and 1970s. This study of the area also reveals that the Forest Service's planning process was fundamentally flawed because Forest Service planners often lacked scientific data to support management decisions and downplayed the sigificnace …

Enculturing Nature, William Lloyd Cornett

Dissertations and Theses

Human activity is embedded within a myriad of seldom-acknowledged ecological relationships. Anthropology and ecology, two holistic disciplines concerned with these activities, struggle with the topic of human/nature relationships because both are grounded within larger western discourses separating human behaviors from those of the natural world. This thesis examines the histories of anthropology and ecology in the 20th Century, and the effect these disciplines have had upon the formulation of contemporary urban worldviews that are based upon the separation of humans from nature.

Portland’S Prostitution-Free Zone Ordinance : The Social Construction Of Prostitution As A Social Problem, Kristin Aman Christophersen

Dissertations and Theses

This study explored the process and the nature of the claims and claimsmaking activities in the most recent presentation of prostitution as a social problem calling for a specific response, the prostitution-free zone ordinance. Integrating the conceptual framework of Best's (1995) constructionist approach to social problems with Strauss and Corbin's (1990) grounded theory approach, this study examined 1) the role and influence of different claimsmakers and their claims in the passage and implementation of the prostitution-free zone ordinance, and 2) how three perspectives (social control, moral reform and radical feminism) are differentially reflected in claimsmakers' framing of prostitution, as well …

Reporting The Counterrevolution : The Sed Perception Of “Prague Spring” As Reported In Neues Deutschland January 1-August 21, 1968, Lee Allen Evans

Dissertations and Theses

In 1968, Czechoslovakia attempted to sweep the ashes of Stalinism from its path to socialism. The reform-movement "Prague Spring" united the nation with a goal to achieve a more just form of socialist society. When the Soviet Union and its Warsaw Pact allies invaded Czechoslovakia on August 21, 1968, they destroyed this dream.

The purpose of this thesis is to show how the SED interpreted events in Prague and presented their analysis to the East German public. Although imbedded in events in Czechoslovakia, this is an essay on German history.

The SED presented a public image of complete unity. The …

The Green Dyadic Formulation For Radiation Problems With Arbitrary Sources Embedded In Stratified Multi-Layer Structures : Application To Molecular Fluorescence Problems, Robert Lyle Hartman

Dissertations and Theses

The Green Dyadic method for computing fields due to current sources between parallel interfaces of dielectric materials is studied. Computer implementation of the method as presented in a well-known article leads to the conclusion that significant errors are present. Two dissimilar methods of solution lead to corrected formulations which are shown to be equivalent. The same correction is found in the research literature. For confirmation, computations are performed in examples involving an emitting dipole by both the Green dyadic method and Sommerfeld' s Hertz vector method. Finally, the computational examples are used to compute fluorescence decay rates for emitting dipoles …

Gender Socialization Of Preschoolers : The Influence Of Parental Orientation And Preschool Environment, Alice Blackwell Passannante

Dissertations and Theses

Because there are different sets of attitudes and standards that are applied to girls and boys, and because society is permeated with messages delineating the differences between females and males, there is a rapid accumulation of knowledge by children about those differences. There is a need for further examination of the overall impact of different facets of gender socialization.

The purpose of the present study was to clarify the ways in which parental beliefs and practices as well as daycare environment affect the gender-typing of preschoolers. Seventy-nine children from three different preschools were interviewed using Likert, forced-choice, and open-ended items. …

The Role Of Educational Technology And Motivation In Increasing Flow And Time-On-Task To Enhance Learning, Michael Pullmann

Dissertations and Theses

Technology plays an increasing role in college courses. Student experiences and outcomes may be significantly altered by high-tech course presentation and flexible formats. Models from psychology, such as Csikszentmihalyi's flow theory are useful for understanding quality of experience. Dweck's motivation theory explains why some students may not experience the flow state during school work. The purposes of this study were to: 1) Determine if students in technology-enhanced courses differ from other students on the experience of flow, 2) Test the relationship between flow, motivation orientation, and time-on-task, and 3) Test the relationship between motivation orientation, time-on-task, and student outcomes.

Free Trade, Regionalism, And The Democratic Peace Theory, Julia B. Johnson

Dissertations and Theses

Democratic nations worldwide rarely, if ever, go to war against one another. A variety of reasons for these peace loving democracies are offered in the social sciences literature. Many proponents of the theory of a democratic peace argue that democratic nations do not war against one another because of similar libertarian norms of behavior, and prohibitive structural institutions.

This thesis disagreed with the above assessment of peaceful democratic norms and institutions, and sought instead to investigate the role of economic prosperity as a crucial element of international cooperation. Combining the characteristics of democracy and economic prosperity, more fully rounded out …

Role Of The Warrant In Presidential Debates : 1960, 1976, & 1996, Aaron Nicole Kaio

Dissertations and Theses

Every four years in America we make a decision about which candidate is best suited to be our next president. Over the past twenty years a standard component of the presidential campaign has been televised debates. These debates are supposed to help the public get a better understanding of the candidates' ideas about government, our future, and to demonstrate analytical skills and their ability to think on their feet.

This study set out to see how the candidates' arguments measured up to some basic argumentation standards. According to several scholars, none of the televised presidential debates qualify as 'true debates', …

Self-Consistent Effective Binary Interaction Approximation For Strongly Coupled Multifluid Dynamics, John D. Ramshaw

Physics Faculty Publications and Presentations

An improved self-consistent effective binary diffusion approximation for multicomponent diffusion was recently described [1]. Here we develop an analogous self-consistent effective binary interaction (SCEBI) approximation for simplifying multifluid dynamical descriptions in which each fluid is strongly coupled to the other fluids by pairwise frictional forces. The net drag force on each fluid is the summation of the drag forces due to each of the other fluids. This summation is approximated by a single term proportional to the velocity of the fluid in question relative to an appropriately weighted average velocity. This approximation permits an explicit numerical solution for the fluid …
