Improved Finite Analytic Methods For Solving Advection-Dominated Transport Equation In Highly Variable Velocity Field, Wei Cuifeng

Dissertations and Theses

Solute transport studies frequently rely on numerical solutions of the classical advection-diffusion equation. Unfortunately, solutions obtained with traditional finite difference and finite element techniques typically exhibit excessive numerical diffusion or spurious oscillation when advection dominates, especially when velocity field is highly variable.

One recently developed technique, the finite analytic method, offers an attractive alternative. Finite analytic methods utilize local analytic solutions in discrete elements to obtain the algebraic representations of the governing partial differential equations, thus eliminating the truncation error in the finite difference and the use of approximating functions in the finite element method. The finite analytic solutions have …

Generalized Sylvester Theorems For Periodic Applications In Matrix Optics, Lee W. Casperson, Anthony A. Tovar

Electrical and Computer Engineering Faculty Publications and Presentations

Sylvester's theorem is often applied to problems involving light propagation through periodic optical systems represented by unimodular 2 × 2 transfer matrices. We extend this theorem to apply to broader classes of optics-related matrices. These matrices may be 2 × 2 or take on an important augmented 3 × 3 form. The results, which are summarized in tabular form, are useful for the analysis and the synthesis of a variety of optical systems, such as those that contain periodic distributed-feedback lasers, lossy birefringent filters, periodic pulse compressors, and misaligned lenses and mirrors. The results are also applicable to other types …

Using A Computer Program To Influence The Expectations Senior Adults Have Regarding Hearing Aids, Carol I. Sayre

Dissertations and Theses

A disabling condition that is common for many senior adults is hearing impairment. Studies have shown that a substantial number of people who could benefit from amplification choose not to use hearing aid. Often the reasons may be because they have unrealistic expectations of what hearing aids can do. These unrealistic expectations are not necessarily from personal use, but the senior adult is often influenced by the media, acquaintances, or advertisements. The purpose of this study was to determine if a computer program developed with information about hearing aids and their use could be used to influence the expectations senior …

Implementing Community Policing: A Documentation And Assessment Of Organizational Change, Emmajean Williams

Dissertations and Theses

Four research questions guided this documentation and assessment of the Portland Police Bureau's conversion to community policing. These questions generated a description of the events and circumstances that created the perceived need for change in the Bureau's role and function; a search for justification for selecting community policing as an alternative policing approach; a comparative analysis of past attempts to implement innovative change of a similar dimension in police organizations; and an assessment of the process by which the Bureau implemented this new policing strategy.

The findings indicate that the prominent factors driving this change are first, the limitations of …

Evolution Of Emergent Computation, James P. Crutchfield, Melanie Mitchell

Computer Science Faculty Publications and Presentations

A simple evolutionary process can discover sophisticated methods for emergent information processing in decentralized spatially-extended systems. The mechanisms underlying the resulting emergent computation are explicated by a novel technique for analyzing particle-based logic embedded in pattern-forming systems. Understanding how globally-coordinated computation can emerge in evolution is relevant both for the scientific understanding of natural information processing and for engineering new forms of parallel computing systems.

Molecular Fluorescence Spectroscopy In The Vicinity Of A Microstructure, P.T. Leung, Thomas F. George

Physics Faculty Publications and Presentations

A brief review is presented on fluorescence spectroscopy of molecules in the vicinity of a microstructure, which could be a surface structure, clustered ions/atoms, a colloidal particle in a solution, or a tip in certain molecular probes. This structure can be viewed as microscopic, mesoscopic or macroscopic, depending on the specific environment in which the molecule is located. An overview is given for selected experimental and theoretical aspects of this phenomenon, emphasizing some of the previous modeling work of the authors. Discussion of possible future attempts to explore the phenomenon in more detail is presented at the end.

Getting From Here To There: An Outline Of The Wildlands Reserve Design Process, David Johns, Michael Soulé

Political Science Faculty Publications and Presentations

Turning back the assault on the natural world is a monumental and complex task; even the first step – planning a network of reserves – is an enormous undertaking. This paper is intended as a general guide to the steps needed to produce a regional proposal for a Wildlands reserve system. It is based on an assessment of work underway in some regions, and extensive discussion with regional groups throughout the continent.

Identifying Factors That Influence Perceptions Of Teacher Efficacy As A Means Of Building Capacity For Restructuring Schools: A Case Study Approach, Deborah Sommer

Dissertations and Theses

Recent efforts to restructure schools through increased teacher involvement are likely to fail without a corresponding redesign of the underlying organizational and political structure of schools. Because the current structure of most schools actually prohibits the collaboration necessary to effect change and promotes professional isolation instead, staff members faced with the tasks of restructuring experience frustration more often than success. The changes that do occur are often superficial and cosmetic while the basic hierarchy and mechanisms of control remain intact. Allowing teachers to redesign their schools, specifically to develop new models that promote interdependence and the sharing of professional expertise, …

Some Relationships Between Sedimentary Trace Metal Concentrations And Freshwater Phytoplankton And Sedimentary Diatom Species Composition, Allan Hayes Vogel

Dissertations and Theses

Sediments from 21 Oregon lakes were analyzed for seven metals (Fe, Mn, Zn, Cu, Co, Ni, V) in three forms (exchangeable, organic+sulfides, and oxyhydroxides+ oxides+ carbonates) using a sequential fractionation procedure. The summer epilimnetic filterable concentration of an eighth (Mo) was also determined. Sedimentary diatom remains and summer phytoplankton populations of the lakes were correlated with the 22 metal parameters and with conservative water chemistry parameters, estimators of lake productivity, and watershed geology. Both the sedimentary metals and the two populations of primary producers correlated best with the ecoregions of Omernik and Gallant (1986). A number of species possessed correlations …

Beam Modes Of Lasers With Misaligned Complex Optical Elements, Anthony A. Tovar

Dissertations and Theses

A recurring theme in my research is that mathematical matrix methods may be used in a wide variety of physics and engineering applications. Transfer matrix techniques are conceptually and mathematically simple, and they encourage a systems approach. Once one is familiar with one transfer matrix method, it is straightforward to learn another, even if it is from a completely different branch of science. Thus it is useful to overview these methods, and this has been done here. Of special interest are the applications of these methods to laser optics, and matrix theorems concerning multipass optical systems and periodic optical systems …

Pretrial Release In Criminal Courts: A Study Of Three Oregon Counties, Melvin Earl Degraw

Dissertations and Theses

Pretrial release (PTR) is the permanent or temporary freedom from incarceration for criminal defendants awaiting adjudication of their cases in court. From Anglo Saxon times in England, people accused of non-capital crimes were generally permitted to remain free until judicial officials could hear the charges against them. In America, pretrial release has been advocated by the courts since the colonial era. The U. S. Constitution requires that bail not be excessive, but leaves governments free to decide how bail laws are administered. The study briefly traces the historical developments of PTR up to the present time. The study then centers …

Transgression And Limits In Euripides' Alkestis, Leshu Torchin

Anthós Journal (1990-1996)

This paper seeks to understand Euripides' Alkestis in the terms of the transgression described by both Michel Foucault and Longinus. The first section explores transgression as a process that erases the prior limits in order to reconstruct and redefine them. During this process, limits and boundaries are stripped away. A period of horror and liminality ensues in which the meaning of boundaries comes into question. The second section examines the positionality of death as the primary limit that frames the events of the tragedy. The third Section explores the deteriorating functionality of the gender roles held by Admetus and Alkestis. …

Kurt Tucholsky: Left-Wing Intellectual And Politically-Engaged Journalist, David Johnson

Anthós Journal (1990-1996)

Critics of intellectuals have focused on the naive idealism of intellectuals and their tendency to withdraw from the political theater, instead concentrating on their respective specialties. Tucholsky did not fit into this group of intellectuals, as he was an active participant in the political debates of the day. He polemicized, satirized and criticized. He wrote poems and cabarets. When he saw a theme which needed to be addressed, he tackled it; often many times. He focused on real issues. His methods of satire and criticism were purposefully used to highlight the real problems faced by Germany. Tucholsky may have not …

Spiritual Health: Association For The Advancement Of Health Education Instructors' Attitudes, Practices And Training, Susanne Meyer Christopher

Dissertations and Theses

Health education uses a holistic, multi-dimensional perspective (Hoyman, 1961; Donatelle, 1991; Hales, 1992). In recent years an emergent issue in health education is concern for disproportionate representation among the human dimensions--emotional, social, physical, intellectual, spiritual. Discussion occurs over the apparent underrepresentation of spiritual health in health education materials (Chandler & Kolander, 1990). While the professional literature contains articles discussing the under-representation of spiritual health (Jose & Taylor, 1986; Bensley, 1991), no empirical studies are available to assess the current status of spiritual health in health education materials or the spiritual health attitudes of health educators. This study provides empirical data …

We Are The Vanguard, Not The Norm: Stories Of Successful Minority Students In Predominantly White Graduate Teacher Education Programs, Leslie Rennie-Hill

Dissertations and Theses

Minorities stand increasingly under-represented in the teaching profession; they continue to be under-represented in graduate teacher preparation programs. Despite calls for increased numbers of minority teachers, despite countless well-intentioned recruitment and retention programs, the relative proportion of newly prepared minority teachers is in fact decreasing (Carter & Wilson, 1992). Literally hundreds of studies examine retention programs, identifying the deficits of minorities, noting what program elements work, and establishing characteristics of supportive institutional environments. Unfortunately, knowing what can be done to I increase persistence does not yet translate into doing it. By focusing on a positive correlate--those minority students who successfully …

A New Era Of Water Quality Management In Agriculture: From Best Management Practices To Watershed-Based Whole Farm Approaches, David E. Ervin

Economics Faculty Publications and Presentations

Why is reducing water pollution from agriculture such a stubbornly slow process? Despite several policy initiatives since the 1970s, farms and ranches rank as the primary contributors to impairments of the nation's surface waters [U.S.EPA, 1994b]. Emerging research also points to agricultural chemicals in many cases of groundwater contamination [Barbash and Resek; Mueller, et al.]. After a little reflection, the industry's negative distinction may not be surprising. Covering nearly half the U.S. land base, crop and livestock production inevitably alter natural vegetative cover, apply fertilizers, pesticides and irrigation water, and involve animal wastes. All of these processes can degrade water …

Optimizing Object Invocation Using Optimistic Incremental Specialization, Jon Inouye, Andrew P. Black, Charles Consel, Calton Pu, Jonathan Walpole

Computer Science Faculty Publications and Presentations

To make object invocation efficient, it is important to minimize overhead. In general, overhead is incurred in order to maintain transparency; with the advent of mobile computer systems, persistence, increasing security and privacy concerns, transparency becomes more expensive and overhead is increasing. Invocation mechanisms maintain transparency by finding objects, choosing communication media, performing data translation into common formats (e.g., XDR), marshalling arguments, encrypting confidential data, etc. Performing all of these operations on every invocation would lead to unacceptable performance, so designers often avoid operations by specializing object invocation for more restricted environments. For example, the Emerald compiler performs several optimizations …

Investigations On Glycolipid Production By Pseudomonas Putida Grown On Toluene In Batch And Continuous Culture Conditions, Keith Foorest Dockery

Dissertations and Theses

Utilization of toluene by Pseudomonas putida as its sole carbon and energy source affects morphology, outer membrane protein composition, and glycolipid production. Two strains of P. putida were found to utilize toluene and to coexist in continuous and batch culture. The two strains were designated translucent and opaque, based upon their readily identifiable coloration when grown on Luria agar. The translucent strain was the dominant strain in continuous culture conditions. The outer membrane proteins of P. putida were separated by sodium dodecyl sulphate polyacrylamide gel electrophoresis. When toluene is the carbon and energy source, the trend in protein composition was …

The Decision And Rationale Which Led To Construction On High-Risk Land After The 1964 Alaska Earthquake: Analysis Of Risk-Based Cultural Dissociation, Sheila Ann Selkregg

Dissertations and Theses

Many lives and much property are lost in disasters when individuals and communities choose to ignore information which could mitigate the potential disaster. This case study examines community and individual decision processes and rationale which led to construction of a high-occupancy high-rise courthouse on land designated as high risk after the 1964 Alaska earthquake. The study reviews policy and decision making, psychology, and risk management literature to explore the psychological mechanisms and processes of hazard mitigation decisions.

It questions why individuals and communities choose not to mitigate when they have the information which makes risk mitigation possible. The hypothesis theorizes …
