An Intercultural Analysis Of Differences In Appropriateness Ratings Of Facial Expressions Between Japanese And American Subjects, Patricia Jean Peschka-Daskalos

Dissertations and Theses

In 1971 Paul Ekman posited his Neuro-Cultural Theory of Emotion which stated that expressions of emotion are universal but controlled by cultural display rules. This thesis tests the Neuro-Cultural Theory by having subjects from two cultures, Japan and the United States, judge the perceived appropriateness facial expressions in social situations. Preliminary procedures resulted in a set of scenarios in which socially appropriate responses were deemed to be either "Happy", "Angry" or "Surprised". Data in the experimental phase of the study were collected using a questionnaire format. Through the use of a 5-point Likert scale, each subject rated the appropriateness of …

Geochemistry, Alluvial Facies Distribution, Hydrogeology, And Groundwater Quality Of The Dallas-Monmouth Area, Oregon, Rodney R. Caldwell

Dissertations and Theses

The Dallas-Monmouth area, located in the west-central Willamette Valley, Oregon, consists of Tertiary marine and volcanic bedrock units which are locally overlain by alluvium. The occurrence of groundwater with high salinities has forced many rural residents to use public water supplies. Lithologic descriptions from driller's logs, geochemical (INAA), and x-ray diffraction analyses were used to determine alluvial facies distribution, geochemical and clay mineral distinctions among the units, and possible sediment sources. Driller's log, chemical and isotopic analysis, and specific conductance information from wells and springs were used to study the hydrogeologic characteristics of the aquifers and determine the distribution, characteristics, …

Central America: An Attempt At Modern Economic Growth, Richard Kibbey

Dissertations and Theses

Since World War II the five historic Central American nations, Costa Rica, EI Salvador, Guatemala, Honduras and Nicaragua, underwent a period of aggregate economic growth which was followed by a collapse of dramatic proportions. All five countries experienced an economic downturn in the latter 1970s which led to several years of declining GDP and GDP per capita, together with an economic and social disarray which is typically referred to as "la crisis" in Central American literature.

The intent of this study is to present an argument for the position that the economic collapse of the five Central American nations was …

Difficulties Experienced Procedural Programmers Encounter When Transferring To An Object-Oriented Programming Paradigm, Scott Andrew Machaffie

Dissertations and Theses

Experienced procedural programmers seem to have difficulty when transferring from a procedural language to an object-oriented language. The problem is how to assist the experienced procedural programmers to make this shift. The long term goal of this research is to identify areas where programmers have problems and to develop an automated system to help them overcome these difficulties.

This study examines the class designs produced by procedural programmers and the effect of specifications and domain knowledge on class designs. Two types of specifications were used: those written from a procedural point of view which emphasized the functions and those written …

Job Attribute Preferences Of The Workforce In Polish High Technology Enterprises, Florian Michael Sisavic

Dissertations and Theses

A key precept in work place motivation theory is that management knows what job attributes are valued by the employee. Management can benefit by asking employees what they want from their work experience (i.e., job attribute preferences), rather than assume they know. This is particularly important to Polish high technology companies that are in transition to a free-market economy and to Polish workers who must be appropriately motivated to compete globally.

This study attempts to better understand the job attribute preferences of Polish managers and workers, the potential gaps between Polish managers' perception of their workers' preferences (system), and how …

Residential Options For The Institutionalized Chronically Mentally Ill: The Impact Of Psychosis On Choice, Richard James Stanek

Dissertations and Theses

Discharge planning for hospitalized chronically mentally ill usually involves only verbal descriptions of community residential options. Psychosis often impairs ability to conceptualize abstract information, and quality of the choice process may be poor without describing options in concrete form, i.e., using written descriptions and photographs. A random sample (N= 90) of Dammasch State Hospital (Wilsonville, Oregon) patient population, comprising persons diagnosed schizophrenic, schizoaffective, organic mental disorder, and bipolar, were assigned to three treatment groups, asked to rank six community residential options suited for them when they were ready to leave the hospital. The three treatment groups were presented the same …

Comprehension Of Literate Programs By Novice And Intermediate Programmers, Christopher Forrest Bertholf

Dissertations and Theses

The studies reported herein compare comprehension of Lit style literate programs to that of traditional modular programs documented by embedded comments. Novice and intermediate programmers participated in three experiments designed to determine the comprehensibility of literate programs written using a language-independent system for abstraction-oriented literate programming compared with programs written using traditional modular programming techniques (traditional modular programs). Programs were written in either the C or FORTRAN programming language. Half of the subjects in each group received a literate program, while the other half received a traditional modular program with embedded documentation. Subjects received a problem specification, input and output …

Cross-Cultural Training Of Chinese Managers And Workers By U.S. Companies: A Comparative Cultural Analysis Of The Problems Reported By U.S. Trainers, Linda Vick

Dissertations and Theses

As Western business increases in China and China acquires more technology from the West, the need to effectively train the Chinese workforce becomes more important. Identifying and understanding the perceived problems that Western corporate trainers encounter when they train Chinese may lead to more effective and efficient training programs. This study examines the experiences of trainers, working for American companies, who have designed and implemented training programs for Chinese from the People's Republic of China. The purpose of the study is to identify perceived problems the trainers encounter and to determine whether differences between Chinese and American cultures may account …

The Study Of Malaysian Learners' Strategies While Studying A Second Language, Phoebe Christina Leong

Dissertations and Theses

In the past, the process by which language acquisition took place was largely ignored. Learning strategies were found to reveal much of the processes that occurred in a learner. In recent years, however, there was a greater emphasis in discovering learner's strategies because of the important role it played in helping the learner control his learning. Most researchers (e.g., Rubin 1975, Stern 1974, O'Malley 1985) emphasize not only the importance of learner strategies in helping the student direct his own learning, but they also emphasize the usefulness of transferring strategies used by successful learners to less successful learners. In order …

Communication And Gender: Interviews With Blue-Collar Women, Jeri Lynn Sofka

This thesis explores the interactions between women and men who work in highly-skilled blue-collar trades. The aim of this research is to describe women's perceptions and responses to their on-the-job communicative interactions with male co-workers, supervisors and union officials.

Small focus groups were conducted to produce rich narrative data that was audio recorded for later use by the researcher. The researcher met with the four subjects for three sessions. The interviews lasted three hours each. The researcher also conducted follow-up interviews by phone to clarify subjects' responses. The subjects were provided with an interview schedule of questions prior to the …

The Effect Of Color On Character Recognition: A Study Of The Oregon License Plate, Frank R. Dennis

Dissertations and Theses

This study investigated character color changes on the current Oregon license plate in an attempt to rectify character recognition problems currently experienced with personalized license plates. Red-violet, brown, and purple were tested against the blue color currently used on the Oregon license plate's characters. Aesthetic-preference analyses were conducted to ensure that the potential character color changes maintained the appeal of the current plate. A standard recognition paradigm was used to test errors in letter recognition for the 4 colors.

Fifty-four subjects with normal or corrected normal visual acuity and normal color vision were solicited from undergraduate psychology courses. All 54 …

Smart Memory: An Inexact Content-Addressable Memory, Jack Lee

Dissertations and Theses

The function of a Content-Addressable Memory (CAM) is to efficiently search the information stored in the memory, by using hardware rather than software with a corresponding improvement in searching speed. This hardware allows a parallel search by matching the data stored in memory to a search key rather than sequentially searching address by address as is done in a Random Access Memory. Although existing CAMs are more efficient in finding relevant information than RAM, there are additional improvements that can be made to further improve its efficiency. For example, previous CAMs use a word parallel searching scheme that can only …

Exact Modeling Of Time-Interval-Modulated Switched Networks, Weihe Niu

Dissertations and Theses

The frequency response analysis of switched networks plays a very important part in designing various kinds of power converter circuits. In this thesis two frequency response techniques for analyzing switching power converters are discussed. One method provides a mathematical description which treats the converter as a periodic time varying system. A linearized small signal model is subsequently derived. The major part of the thesis concentrates on this accurate exact small-signal technique. The derivation involves state space representation and the use of the time varying transfer function. A Fourier analysis is performed to show the relationship between the frequency response of …

From The Middle East To The United States: Stressors And Coping Strategies Of Members Of A Sacred Culture Living In A Secular Culture, Angela Taha

Dissertations and Theses

The values and beliefs involved in Islam maintain that religion is embedded in everyday life. Students from countries which subscribe to the tenets of Islam may have a difficult time adjusting to the secular society of the U.S. This study is concerned with the interrelationships among events perceived as stressful, the ways of coping with stress that are reported as most often used, and the reported level of satisfaction with living in the U.S. for the Muslim Arab international students in this study.

A four page survey questionnaire was used as the instrument. The questionnaire was filled out by 102 …

Matching Points To Lines: Sonar-Based Localization For The Psubot, Kevin Blythe Stanton

Dissertations and Theses

The PSUBOT (pronounced pea-es-you-bought) is an autonomous wheelchair robot for persons with certain disabilities. Its use of voice recognition and autonomous navigation enable it to carry out high level commands with little or no user assistance. We first describe the goals, constraints, and capabilities of the overall system including path planning and obstacle avoidance. We then focus on localization-the ability of the robot to locate itself in space. Odometry, a compass, and an algorithm which matches points to lines are each employed to accomplish this task. The matching algorithm (which matches "points" to "lines") is the main contribution to this …

Lola G. Baldwin And The Professionalization Of Women's Police Work, 1905-1922, Gloria Elizabeth Myers

Dissertations and Theses

This thesis traces the emergence of the American policewomen's movement through the career of Portland, Oregon's Lola Greene Baldwin, the first such officer hired by a municipality. It recounts the conditions which marked Baldwin's transition from a volunteer moral purity worker to a professional urban vice detective. The thesis connects Baldwin and her new profession to the Progressive era's social hygiene impulse. It considers how government absorption of the social hygiene agenda influenced the enforcement attitudes and methods of the early policewoman. Further, this work looks at the way Baldwin functioned within the bureaucracies and political structures of her environment. …

The Liberal-Communitarian Debate And The Development Of A Political Conception Of The Person, Kenneth Howard Biggs

Dissertations and Theses

Without doubt, John Rawls's A Theory of Justice is one of the most important statements of Anglo-American political philosophy in the twentieth century. Through a revival of the social contract device, Rawls formulates a set of principles of correct political association ("the right") that he argues must be considered as prior to any conception of the good. These principles apply to all persons as free and equal beings in society, but more importantly they assume some things about the nature of persons in that society.

On the institutional aspect of his theory, Rawls conceives of the state as a neutral …

An Analysis Of The Involvement Of Ten High Schools In Scholastic Aptitude Testing Student Preparation, Elaine Drakulich

Dissertations and Theses

The Scholastic Aptitude Test (SAT) is taken each year by two fifths of the high school graduates (Cameron, 1989). The perception that high SAT scores will either open the door of selective colleges and generate scholarships or that low SAT scores will close off opportunities for the rest of one's life, makes virtually every student who invests the three hours of time required to take the test extremely anxious about doing as well as possible (Whitla, 1988). Significant relationships between identified preparation techniques and the perceived effectiveness of those techniques by students and staff can be very useful information for …

Occurrence Of Phonological Processes Within Two Pragmatic Categories In Normal And Speech-Delayed Children, Betsy Ann Bergman

Dissertations and Theses

Research into the eventual suppression of phonological processes among children has centered on the influence of phonetic context and semantic-syntactic factors. Researchers have described various factors that would account for the variability found in normal and speech-delayed children's use of phonological processes. Researchers have found associations between phonological process use and language form and content, although there is a paucity of information pertaining the effect of language use on phonological performances. This study examined the phonological process use within two pragmatic functions-assertiveand responsive utterances-used by 15 normally developing and 15 speech-delayed 3-year-olds. These groups were matched for age, sex, and …

Certain Phonological Skills In Late Talkers, Catherine Marie Ryan-Laszlo

Dissertations and Theses

While there is general agreement among researchers in the field of language and learning disabilities upon the language hypothesis for reading failure, little research has been explored concerning the relationship between the phonological production skills of preschool children and the same children's prereading abilities in kindergarten.

This study examined two aspects of phonological skill (a) the relationship of early phonological production errors and later success on phonological awareness and general prereading skill, and (b) determining if prereading deficits in a group of children with a history of language delay reside specifically in the phonological awareness items or the prereading score …

An Analysis Of Conceptual Metaphor In Marital Conflict, Anne Elizabeth Burgermeister-Seger

Dissertations and Theses

This thesis investigates metaphoric structure revealed during discussions about conflict, and poses the general question: What conceptual metaphors do married individuals use to structure their marital conflict? Theoretical issues of metaphor analysis and general issues of conflict management are reviewed, providing a background for the study's approach to data collection and analysis. Eight married individuals were interviewed. Interviews were tape recorded. The interview schedule was structured around issues of topic, setting, process, response, and communication of typical, as well as a most recent, marital conflict. More specific probing followed respondents' comments. Using techniques of interpretive analysis, transcripts from the interviews …

Novel Cylindrical Illuminator Tip For Ultraviolet Light Delivery, Hanqun Shangguan

Dissertations and Theses

The design, processing, and sequential testing of a novel cylindrical diffusing optical fiber tip for ultraviolet light delivery is described. This device has been shown to uniformly(+/- 15%) illuminate angioplasty balloons, 20 mm in length, that are used in an experimental photochemotherapeutic treatment of swine intimal hyperplasia. Our experiments show that uniform diffusing tips of < 400 micron diameter can be reliably constructed for this and other interstitial applications. Modeling results indicate that this design is scalable to smaller diameters. The diffusing tips are made by stripping the protective buffer and etching away the cladding over a length of 20 mm from the fiber tip and replacing it with a thin layer of optical epoxy mixed with A/203 powder. To improve the uniformity and ease of fabrication, we have evaluated a new device configuration where the tip is etched into a modified conical shape, and the distal end face is polished and then coated with an optically opaque epoxy. This is shown to uniformly scatter - 70% of the light launched into the fiber without forward transmission. To our knowledge, we are the first to use this device configuration, and we have achieved a uniform cylindrical pattern of laser energy with uniformity < ± 15% of the average value. A simple computational model suitable for the interpretation of laser energy irradiance along the bare core surface of multimode optical fiber tips is proposed and experimentally verified. The model used is based on geometrical optics and Gaussian approximation. Good agreement is obtained between the calculation and experiment. We have measured the optical properties of the tips through all the sequences of the fabrication. The performances of the diffusing tips for illuminating angioplasty balloons are then evaluated by Ultraviolet Light at 365 nm. A Ti:Sapphire Ring Laser System with a doubling crystal pumped by an argon ion laser is used to generate the wavelength in this study.

Minimization Of Permuted Reed-Muller Trees And Reed-Muller Trees For Cellular Logic Programmable Gate Arrays, Lifei Wu

Dissertations and Theses

The new family of Field Programmable Gate Arrays, CLI 6000 from Concurrent Logic Inc realizes truly Cellular Logic. It has been mainly designed for the realization of data path architectures. However, the realizable logic functions provided by its macrocells and their limited connectivity call also for new general-purpose logic synthesis methods. The basic cell of CLi 6000 can be programmed to realize a two-input multiplexer ( A*B + C*B ), an AND/EXOR cell ( A*B Ea C ), or the basic 2-input AND, OR and EXOR gate. This suggests to using these cells for tree-like expansions. These "cellular logic" devices …

Language And Memory Development In The Three And Four Year Old, Caroline Prater Moffatt

Dissertations and Theses

Although there is agreement in the literature that memory is required for language, there is disagreement as to whether certain memory abilities are prerequisite for language. There has been a significant amount of research in the field of memory development as it relates to language; however, little research has been done in the area of memory and language development in the preschool aged child.

This study examined two aspects of auditory memory and language development in the preschool child: (a) the auditory memory abilities of delayed language children versus normal language children, and (b) determining if there is a relationship …

Cognitive Development Of Bilingual Korean-Americans In An Oregon School District, Kimiko Okada King

Dissertations and Theses

This research examined whether bilingualism would accelerate or hinder the cognitive as well as academic development of the Korean American individuals in an Oregon school district by analyzing the standardized test scores at grades 3, 5, 7, and 9. Eleven monolingual and 27 bilingual students released the Survey of Basic Skills (SBS) as well as Cognitive Abilities Test (CogAT) scores for this study.

The analyses of the test scores revealed that the Korean-American students in this school district were performing at a much higher level against the national norm (the 50th percentile), or the school district norm (the 75th percentile). …

Dynamics Of Ultrashort Pulse Generation And Amplification In Dye Lasers, Shuanghua Jiang

Dissertations and Theses

The dynamics of ultrashort pulse generation and amplification in dye lasers is studied in this dissertation. In particular, we have developed general semiclassical models for ultrashort pulse dye laser amplifiers and oscillators. These models start from Maxwell's equation for the electric field and density matrix equations for the active laser medium. A finite coherence time or phase memory time of the molecular wave functions, a finite vibrational relaxation time for the lower electronic state of the dye laser transition, an isotropic molecular orientational distribution, and an arbitrary pump polarization are all taken into account. Based on these models, specific topics …

Friendship Patterns Of Chinese Students And Their Adjustment In The United States, Changhua Wang

Dissertations and Theses

International students who experience difficulties in a new culture are often considered to have suffered a breakdown in their normal healthy psychological functioning, and therefore need therapy and counselling (Pedersen et al, 1976). This study views failure and problems experienced by the sojourner as a result of lack of the necessary new social skills and knowledge. Social networks, particularly friendships, are thus extremely important in that such networks are not only source of social support [sic], but also major channels through which such skills and knowledge are acquired [sic].

1. Guided by social support theories and social skills theories, this study …

Second Language Use In The Workplace: A Case Study Of A Dental Hygienist, Gina L. Crocetti

Dissertations and Theses

This paper describes a case study of a non-native speaking (NNS) dental hygienist in her work environment. The subject learned English by learning to become a dental hygienist rather than through formal language education. Participant observation and discourse, event/network, and componential analyses were the methods used to analyze the subject's communication in her work setting.

The philosophical question as to how ESP differs from ESL is raised and elements of the work setting and the NNS workers' communication with interlocutors in that setting are identified to aid educators in teaching ESP courses. Questions ESP educators might address in designing and …

Dissertations and Theses

The Social/HMO Demonstration evaluates the feasibility of expanding Medicare Supplemental Insurance benefits to cover a limited amount of ICF and community based long-term care (LTC) services provided under a comprehensive HMO benefit package for capitated Medicare beneficiaries. The policy research question addressed by this study is whether adding an Expanded Care Benefit (ECB) to the capitated HMO benefit package offered by Kaiser Permanente (KP) changes utilization patterns and costs of ICF services, and the probability of becoming Medicaid eligible. This study provides descriptive information regarding this policy research question. The research goal of this study is to measure the extent …

Urban Regimes And Downtown Planning In Portland, Oregon And Seattle, Washington, 1972-1992, Mark Richard Bello

Dissertations and Theses

Portland and Seattle are often considered to be divergent in character, partly because civic leadership in each city has a different vision. The adoption of contrasting downtown core plans, projects, and policies in each city allows us an opportunity to understand the nature of each city's regime. As defined by Elkin, an urban regime is the community's governing coalition, those who exercise public authority in a legal sense and those private actors able to act collectively and bring concerted influence to bear.

The time frame for this study begins with the first modern planning document, the 1972 City of Portland …
