Lexico-Semantic Influence In Interlingual Transfer, Guy-Luc Achille Levesque

Dissertations and Theses

The present study replicates research by Tomoko Takahashi (1984) on lexico-semantic patterns used by students in an acquisition poor environment. The purpose of the current study was to determine how an acquisition rich environment affects learners' use of four lexico-semantic patterns: congruence occurs when the L1 definition of a lexical item forms a one-to-one correspondence with the L2 lexical item; convergence occurs when the L1 lexical item has broader applications than the L2 lexical item; divergence occurs when the L2 lexical item has broader applications than the L1 lexical item; and semantic gap occurs when the L1 lexical item has …

An Assessment Of The Riparian-Influenced Salmonid Habitat Features Of Johnson Creek, Portland, Oregon, Andrew Greiff Gude

Dissertations and Theses

Pacific salmon populations in Johnson Creek, Portland, Oregon have been adversely impacted by urbanization, and by residential and agricultural land development. Ecological impacts include loss or depletion of riparian vegetation features which directly influence stream and associated salmonid ecology. This research examines the nearstream riparian zone's contribution to instream habitat complexity for anadromous salmonids in Johnson Creek. Visual surveys were conducted on over half the stream length. Five features were assessed to determine the extent of riparian influenced stream habitat including, overhead enclosure, overhanging vegetation, undercut banks, and large and small woody debris and root wads. The stream survey showed …

Adaptive Notch Filter, Yuchen Huang

Dissertations and Theses

The thesis presents a new adaptive notch filter (ANF) algorithm that is more accurate and efficient and has a faster convergent rate than previous ANF algorithms. In 1985, Nehorai designed an infinite impulse response (UR) ANF algorithm that has many advantages over previous ANF algorithms. It requires a minimal number of parameters with constrained poles and zeros. It has higher stability and sharper notches than any ANF algorithm until now. Because of the special filter structure and the recursive prediction error (RPE) method, however, the algorithm is very sensitive to the initial estimate of the filter coefficient and its covariance. …

Factors That Motivate Washington State Teachers To Participate In Professional Growth And Development, Dolores Adan Heisinger

Dissertations and Theses

The major focus of this study was the identification of factors that motivate teachers to participate in professional growth and development activities. Although teachers may be motivated to participate in staff development for different reasons, it was hypothesized that common factors forming an identifiable incentive profile could be found. Within the focus of the study, three primary questions were asked: (a) What are the needs, incentives or motivators that influence teachers to further their professional development? (b) What are the relative strengths of the various needs, incentives or motivators? and (c) How do the incentive structures of teachers differ based …

Source Rock Geochemistry Of The Southern Tyee Basin, Southwest Oregon, David E. Long

Dissertations and Theses

This study examined source rock geochemistry of the southern Tyee Basin. Total organic carbon, rock-eval pyrolysis, vitrinite reflectance, thermal alteration index and visual assessments were performed on splits from cutting samples from five wells and on outcrop samples from four measured sections. Organic matter was found to be dispersed, averaging about 0.5 weight percent. The organic matter is primarily terrestrial in origin, or type I l l , with low potential for gas production and no oil potential. Three coal samples are clearly the richest sources of organic matter examined in this study.

Portland's Multifamily Recycling Program: A Study Of Coproduction Policy Implementation And Citizen Involvement, William Barry Messer

Dissertations and Theses

This study is on coproduction as a governing policy instrument. Coproduction can be understood as the joint production of services by local officials and individual citizens intended to raise the quality and or amount of service provision. The concept of coproduction as developed in this study suggests that urban services are not simply created by officials and delivered to a passive public. Rather that actions of citizens are an integral part of the service production process. The study purposes are two-fold: (1) to construct a model of coproduction which provides a basis by which citizen involvement in the provision of …

The Determinants Of Women's Work: A Case Study From Three Urban Low-Income Communities In Amman, Jordan, Taghrid Khuri Tubbeh

Dissertations and Theses

This study addresses the determinants of women's economic activity in three low income communities in Amman, the capital of Jordan. These communities represent what is typically referred to as "pockets of urban poverty." Besides addressing the demographic and socio-economic variables, the study identifies and includes cultural variables in a model of female labor force participation. Modern economic systems developed definitions and measurements of productivity that render the majority of women's work as non-productive. Activities within the domestic sphere that do not earn monetary returns are not measured as productive economic activities, and hence are dropped from the calculations of gross …

The Schooling Of Vietnamese-American High School Students In Oregon: Their Perspectives, Minh Van Tran

Dissertations and Theses

Research on the education of Vietnamese-Americans is very limited, and mainstream media continue to project Vietnamese students either as high achievers or gang affiliated (Castro, 1983; Davis & McDaid, 1992). This kind of projection can mask the real issues that Vietnamese students are facing. Based on Cummins' (1979) Contextual Interaction Theory, this study examined the views of Vietnamese-American high school students in Oregon regarding their schooling under four major areas: Community Background Factors, Educational Input Factors, Instructional Treatment, and Student Input Factors. In particular, this study examined factors, within the above four areas, pertaining to the schooling of Vietnamese-American high …

A Simultaneous Route-Level Transit Patronage Model: Demand, Supply, And Inter-Route Relationship, Zhongren Peng

Dissertations and Theses

It is observed that transit riders are responding to service changes while transit planning is responding to ridership changes, or that transit patronage and service supply are highly interrelated. It is also noticed that transit riders transfer from route to route, the introduction of new service may draw some riders from the existing routes, which implies transit patronage on a route is also affected by other parallel and intersecting routes. An analytic tool is needed to examine these complex relationships in the transit system. This study has developed a quantitative model by incorporating these interactions into a simultaneous system. The …

Oregon Primary Care Physicians' Support For Health Care Reform, Timothy Alan Baker

Dissertations and Theses

This dissertation studies Oregon primary care physicians' attitudes toward health care reform. Two models of reform are examined: one, health care rationing such as that proposed by the Oregon Health Plan (OHP); and, two, support for national health insurance (NHI).

This work examines the necessity for changing the present health care system, traced from the early origins of the medical profession to the present day health care "crisis." The high cost of health care is examined and an overview of the OHP is provided, including citations from John Kitzhaber, M.D., author of the plan.

Overall, Oregon primary care physicians overwhelmingly …

Private Profit Versus Public Service: Competing Demands In Urban Transportation History And Policy, Portland, Oregon, 1872-1970, Martha J. Bianco

Dissertations and Theses

This dissertation is a case study of the history of urban transportation policy in Portland, Oregon, between 1872 and 1970. The emphasis is on mass transit policy formulated and implemented by the private and public sectors as response to crises within both the local transit industry and the urban political economy. These crises are placed in the context of the continuing conflict between the industry's right to profit and its obligation to meet the competing demands of its constituencies: ridership's demands for low fares and comprehensive service; labor's demands for competitive wages; downtown businesses' demands for peak-hour service; and the …

A Study Of Personal Attributes Associated With Marginality And Failure Of Preservice Teachers In The Terminal Field Experience, Sharon Irene Bancroft

Dissertations and Theses

This study examines the impact of personal attributes on student teachers' failure to pass or marginal success in the terminal field experience. Interviews were conducted of faculty at five Washington and two Oregon teacher education programs, who served as supervisors of student teaching. The interview was of the "depth" type described by Masserik (1981,) open-ended, interactive, and designed to encourage the sharing of case histories and subjective experience according to interpretive inquiry protocol as outlined by Lincoln and Guba (1985.) Its goal was to surface fundamental assumptions about and idiosyncratic language used to describe those attributes deemed critical to a …

Case Studies Of The Structure, Dynamics, And Outcomes Of Interdisciplinary Team Organization In Oregon Middle Schools, Gail Lyon

Dissertations and Theses

Middle school literature advocates interdisciplinary team organization as a structure that enhances student learning and teacher satisfaction. In an interdisciplinary team, teachers responsible for different content areas collaboratively plan the instructional program for a shared group of students. Yet, fewer than fifty percent of the nation's middle schools use an interdisciplinary team structure, and research indicates that teams are fragile and temporary. Few studies were found that described interdisciplinary team organization at the team or individual teacher level.

The purpose of this case study is to describe the structure, dynamics, and outcomes of interdisciplinary teams of teachers in middle schools. …

The Spatial Distribution Of Ground Stone Tools As A Marker Of Status Differentials In A Chinookan Plank House On The Lower Columbia River, John William Wolf

Dissertations and Theses

Social status was an integral part of the social structure of Northwest Coast societies. The presence of ranked social structures and household space based on rank is reported in the ethnographic literature. Archaeologists have long searched for independent and verifiable means to infer social structure from archaeological deposits. Burial goods have been used to identify status differences. Do other items of material culture also reflect such differences?

The purpose of this study was to ascertain whether or not the distribution of certain tools recovered from a Chinookan plank house on the lower Columbia River paralleled the household residence location that …

Aids-Preventative Behaviors And The Psychological Costs Of Behavior Change, Howard Balshem

Dissertations and Theses

This study examined the effects of behavior change on psychological health among gay and bisexual men of Portland, Oregon who were at risk for contracting AIDS. Cross-sectional self-reports of personal experiences were obtained in Summer, 1991. Sexual behaviors were used as predictors of self-efficacy, depression, anxiety, and subjective well-being. Adopting safer sexual behaviors was psychologically more costly than continuing to engage in high risk behaviors, or long-term adherence to safer behaviors. Behaviors amenable to short-term change differed from those conducive to long-term maintenance. Behavior change was also found to have a beneficial effect on self-efficacy.

These findings suggest that behavior …

Atmospheric Hydrocarbon Analysis, Dawei Han

Dissertations and Theses

This treatise studied two correlated important issues in atmospheric chemistry: real-time monitoring of ambient air and removal mechanisms of atmospheric hydrocarbons. An analytical system was designed for the purpose of identification and measurement of sub-ppb level hydrocarbons of different reactivities in air samples. This analytical system was then applied to a series of smog-chamber studies which simulated the removal of reactive hydrocarbons from the atmosphere by reaction with hydroxyl radicals. Six representative atmospheric hydrocarbons (hexane, octane, toluene, m-xylene, a-xylene and mesitylene) were selected for these experiments. The experimental data indicated that the decay of atmospheric hydrocarbons under laboratory conditions is …

Ethnic Identity Changes Among Hong Kong Chinese Americans, Pui-Lam Lo

Dissertations and Theses

During the last ten years, the number of Hong Kong Chinese migrating to the U.S. has increased. These new immigrants, with knowledge and life experiences shaped by the urban metropolis of Hong Kong, have begun to influence different aspects of Chinese communities in U.S. cities. A study of this group of Hong Kong Chinese provides a better understanding of how they have adapted to their new environment and how they have come to recognize themselves as Hong Kong Chinese Americans. In reviewing the available literature, very few studies have dealt with the identity changes of this group of people. Hence, …

Development Of High-Technology Industries In The Portland/Vancouver Metropolitan Area: An Analysis Of Regional And Intraregional Factors Affecting High-Tech Firm Locations, Ulf Eichner

Dissertations and Theses

This thesis aims to investigate local conditions of high-tech industry development in the Portland/Vancouver CMSA. To do so, the research proceeds in four major stages. First, it is analyzed how historical factors contributed to the rise of high-tech industries in the CMSA. The second part consists of mapping the distribution pattern of hightech establishments. The U.S. Bureau of Census' County Business Patterns statistics are used to calculate the number of high-tech establishments and employees by branch (SIC code) and county; two high-tech directories help to identify the exact firm locations. Thirdly, an explanatory set of locational factors is established, based …

Modeling And Simulation Of Bipolar Transistor At Low Temperature, Swarupa Madhav Nerurkar

Dissertations and Theses

The BICMOS technology which integrates the CMOS technology with bipolar technology has drawn considerable attention as an attractive VLSI technology because of the high speed performance and low power consumption of the BICMOS. However, continued down scaling of CMOS devices has caused increased concerns with problems such as latch up, hot carriers and short channel effect. Most of the above mentioned problems can be avoided by operating the CMOS at liquid-nitrogen temperature(LNT). At low-temperatures, the CMOS exhibits lower sub threshold leakage, higher carrier mobility (which yields improved speed performance), and a steeper logarithmic currentvoltage slope. On the other hand, the …

Pattern Recognition And Erp Waveform Analysis Using Wavelet Transform, Hong Qi

Dissertations and Theses

Wavelet transform provides an alternative to the classical Short-Time Fourier Transform (STFT). In contrast to the STFT, which uses a single analysis window, the Wavelet Transform uses shorter windows at higher frequencies and longer windows at lower frequencies. For some particular wavelet functions, the local maxima of the wavelet transform correspond to the sharp variation points of the signal. As an application, wavelet transform is introduced to the character recognition. Local maximum of wavelet transform is used as a local feature to describe character boundary. The wavelet method performs well in the presence of noise. The maximum of wavelet transform …

The United States-Japan Security Treaty Of 1951: An Essay On The Origins Of Postwar Japanese-American Relation, Christopher S. Johnson

Dissertations and Theses

The early September day in 1951 that brought the Pacific War to an official end, with the signing of a treaty of peace, concluded as representatives of Japan and the United States signed the Bilateral Security Treaty. The security treaty symbolized new realities of international relations, just as the peace treaty had buried the old. By cementing into place a strategic alliance between the former Pacific antagonists, the treaty represented the great and lasting achievement of postwar American diplomacy in Asia. Nevertheless, the treaty was both the outcome and the perpetuation of a stereotyped and lopsided relationship, now fixed firmly …

A FDD is a directed function graph that represents the recursive execution of Reed Muller expansion.

A family of decision diagrams for representation of Boolean function is introduced in this thesis. This family of Kronecker Functional Decision Diagrams (KFDD) includes the Binary Decision Diagrams (BDD) and Functional Decision Diagrams (FDD) as subsets. …

Determining The Property Value Impact Of Landfills, Okwuchukwu Gerald Uba

Dissertations and Theses

The decline in property value can be due to owner's act or exogenous act from the operation of landfills. Landfill neighbors, especially home owners, perceive landfill operation to pose environmental safety problem such as ground water contamination and methane gas leakage that could affect home value.

Owners of landfills, especially those landfills that accept only dry waste (limited purpose landfill), claim that since their facilities meet the requirements of environmental regulations and the type of waste they accept could not possibly produce methane gas and leachate there is no property value impact of their facilities.

Several studies have shown that …

Vertex Ordering For A Partitioning-Based Fitting Algorithm For An Epld Device, Tongjun Gao

Dissertations and Theses

As the Application-Specific Integrated Circuit(ASIC) technology develops to the trend of high density and modulization, the ASIC device market has been dominated gradually by the more complex Erasable Programmable Logic Devices (EPLDs) and the Field Programmable Gate Array(FPGAs) instead of the ordinally Programmable Logic Devices(PLDs). Meanwhile, the design automation system for such programmable devices has also moved from schematic entry design to high level hardware description language entry design. Usually, the whole design automation process consists of three phrases, the high level hardware description language compiler, the logic synthesis stage and the layout synthesis stage. Though the layout synthesis stage …
