Philosophy In The Wilderness, Jamie P. Ross

Women, Gender, and Sexuality Studies Faculty Publications and Presentations

An analysis of the team-taught course, Knowledge, Art & Power: The Social Construction of Knowledge. It critically analyzes and rejects both of the following claims: 1. Knowledge consists of eternal truths, 2. Knowledge is relativistic. In so doing, we focus on an understanding that knowledge serves selective interests; knowledge has a teleology (purpose)- i.e. power.

In this course we examine and analyze the relationships among and between knowledge, power and art. That means we must first understand what counts as knowledge. One way of understanding what counts as knowledge is to understand the way in which power is defined …

The Development Process Of An Assessment Instrument For The Supervision Of Teacher Education Interns, Tuula Heide

Northwest Journal of Teacher Education

The purpose of this article is to describe the development process of an assessment instrument for the supervision of teacher education interns. The assessment instrument was developed in several phases. After literature review in the area of supervision and evaluation of teacher education interns, a steering committee and the researcher developed the first draft of the instrument. The second draft of the instrument was developed based on the survey results asking for respondents' perceptions of the first draft. Finally, the final draft of the instrument was constructed after a pilot study, based on the results of the surveys administered at …

Diversity And School Reform, Terry Armstrong

Northwest Journal of Teacher Education

For the past century, school reform has centered around political solutions. Numerous attempts have been made to improve the education of youth. The advent of neuroscience research has given educators new ways of examining conditions affecting school achievement. The list of these conditions is large. Communities seeking to improve schools need to examine biological factors which may impinge on school success.

Erps And Strategy: First, Do No Harm, Kristi Jane Yuthas, Catherine Banbury, Darrell Brown

Business Faculty Publications and Presentations

ERP and other systems projects are now commonly preceded or accompanied by reengineering efforts. Traditional reengineering projects use a 'clean sheet' approach, in which companies attempt to design ideal processes without being bound to existing processes and constraints. When reengineering is associated with information technology (IT) implementation, the more common approach is known as 'tool-driven' or 'system-enhanced' reengineering. Under this approach, the new processes are designed with explicit attention to the opportunities and constraints presented by the capabilities of the new information system. Although IT-related reengineering approaches have matured through time, they have not kept pace with current perspectives on …

Rate-Matching Packet Scheduler For Real-Rate Applications, Kang Li, Jonathan Walpole, Dylan Mcnamee, Calton Pu, David Steere

Computer Science Faculty Publications and Presentations

A packet scheduler is an operating system component that controls the allocation of network interface bandwidth to outgoing network flows. By deciding which packet to send next, packet schedulers not only determine how bandwidth is shared among flows, but also play a key role in determining the rate and timing behavior of individual flows. The recent explosion of rate and timing-sensitive flows, particularly in the context of multimedia applications, has focused new interest on packet schedulers. Next generation packet schedulers must not only ensure separation among flows and meet real-time performance constraints, they must also support dynamic fine-grain reallocation of …

Black Women's Health: A Content Analysis Of The Journal Of The American Medical Association, The American Journal Of Public Health, And The New England Journal Of Medicine (1989-1998), Tonia Marie Burkett

Dissertations and Theses

According to the National Vital Statistics Report (1998), Black women age 45-64 are ten times more likely than white women of the same age to die from diseases of the heart. They are five times more likely to die from diabetes. The goal of this study was to examine how articles published in leading medical journals between 1989 and 1998 accounted for such differences in health outcomes among Black and white women.

The explanatory content of the articles was analyzed and coded according to four types of attributions: genetic/biological, cultural/behavioral, structural/socioeconomic and alternative. Each type of explanation derives from different …

Control Challenges In Multi-Level Adaptive Video Streaming, Dylan Mcnamee, Charles Krasic, Kang Li, Ashvin Goel, Erik Walthinsen, David Steere, Jonathan Walpole

Computer Science Faculty Publications and Presentations

Streaming video is one of the fastest-growing applications of the Internet. The Internet’s diversity and dynamism demands that video streams adapt to ensure maximum quality at all times. This paper describes the control challenges we have encountered in the Quasar project’s “multi-level” adaptive streaming video player. We first describe the framework and environment of the player. This framework uses software feedback to control resource allocation as well as the quality of media delivery. We present the control challenges raised by our framework, which include horizontal and vertical feedback composition, difficult to model systems, and unpredictable, non-linear actuators. We describe some …

Gis Enhancements Using Gps Technology, Marc R. Beckel

Dissertations and Theses

Global Positioning System (GPS) technology is a viable tool for the collection and creation of Geographic Information System (GIS) databases. Organizations have turned their attention to using this tool to develop new databases for their existing GIS. The integration of these new GPS derived databases with older existing databases leads to both technical and organizational repercussions. With the integration of GPS derived data, an organization's existing GIS requires enhancements to GIS databases and the organization must be prepared to manage the integration.

This thesis examines the technical issues that occur due to integration and conflation of GPS data in an …

The Effects Of An Outdoor School Program On 6th-Graders’ Empathy And Attitudes Towards Nature, Carolyn Ann Occhipinti

Dissertations and Theses

Past research in environmental psychology and education has shown that outdoor experiences such as wilderness adventure camps and environmental education programs may result in increases in participants' self-esteem, sense of connectedness to the natural world and environmental awareness. Developmental research has suggested a link between high self-esteem and increased levels of empathy.

The present study was intended to explore possible effects of nature experiences on empathy development, and to add to our understanding of the relationship between people and the natural environment by measuring four aspects of children's subjective experiences: empathy, self-esteem, sense of connectedness to the natural world, and …

The Early Years In African American Education: A Life History Approach To Evaluating Control Theory, Beverly Diane Logan

Dissertations and Theses

The concern of this study is educational achievement, disproportionately low among inner-city African-American students. Because education is so highly valued, particularly among African-Americans, underachievement is considered deviation from cultural norms.

Social control theory attempts to explain why people conform to social norms in spite of pressures toward deviance. Many adverse pressures encountered in inner-city environments and persistent features of institutional racism toward blacks in school make underachievement understandable. Hirschi's (1969) control model, therefore, seemed most appropriate for examining black student achievement.

Control theory holds that individuals conform to cultural norms when their behavior is controlled through established social bonds, which …

Magmatic Processes Operating During The Middle To Late Pliocene And Pleistocene Along The Transition Zone Near 43º North, Christy L. Lee

Dissertations and Theses

A geochemical and structural transition zone exists between the Cascades and Basin and Range provinces in Oregon. Geologic mapping in this area has allowed the definition of six volcanic rock sequences: 1) interfingered alkali-rich basaltic trachyandesite to trachydacite lava flows and low-alkali basaltic andesite lava flows, 2) HAOT lava flows, 3) basaltic andesite lava flows, 4) andesite lava flows and vent deposits with minor basaltic andesite lava flows, 5) HAB lava flows, and 6) interfingered basaltic andesite, andesite, and trachyandesite lava flows.

Geochemical models of sequence 1 alkali-rich rocks suggest the fractionation of the parent assemblage plag (An₅₅)+magn+ol±aug …

Renaissance Courtesy And Book Vi Of The Faerie Queene, Matthew S. Martini

Dissertations and Theses

Book VI of Edmund Spenser's The Faerie Queene, with its chivalric and pastoral characteristics, has confounded critics for several generations. This thesis provides a chronological reading of Book VI that addresses many of its problems in the context of conduct manuals such as Baldassare Castiglione's The Book of the Courtier and Stefano Guazzo's Civile Conversation. Rather than dismiss many of the tensions and contradictions in the text, this study seeks to embrace them by interpreting them with Mikhail Bakhtin's theory of dialogism as expressed in The Dialogic Imagination.

In chapter one, connections are made between the opening …

An Evaluation Of Recidivism Rates For Resolutions Northwest's Victim-Offender Mediation Program, Karin Jewel Stone

Dissertations and Theses

Victim-offender mediation, a component of restorative justice, has been a valuable tool for rehabilitating juvenile offenders since the late 1970s. Victim offender mediation brings crime victims and offenders together to reach agreements for restitution and community healing. Resolutions Northwest, a non-profit organization in Multnomah County, offers a victim-offender mediation program to juvenile offenders and their victims.

The purpose of this study was to analyze the recidivism rates for juvenile offenders who went through Resolutions Northwest's victim-offender mediation program as opposed to offenders who went through the traditional justice system. It was hypothesized that the participants in this program would have …

Shubnikov–De Haas Effect In The Superconducting State Of An Organic Superconductor, J. Wosnitza, S. Wanka, J. Hagel, R. Häussler, H. V. Löhneysen, J. A. Schlueter, U. Geiser, P. G. Nixon, Rolf Walter Winter, Gary L. Gard

Chemistry Faculty Publications and Presentations

We report the observation of Shubnikov–de Haas (SdH) oscillations in the mixed state of the organic superconductor β″-(BEDT-TTF)₂SF₅CH₂CF₂SO₃ (Tc≈4.4K). At low temperatures the SdH oscillations persist clearly below the upper critical field Bc₂(0)≈3.6 T almost down to the field where the resistivity vanishes. Rather unusually, no additional damping of the SdH-signal amplitude — as well as of the de Haas–van Alphen amplitude — is observed in the superconducting state. This indicates that the damping in the vortex state of this quasi-two-dimensional superconductor is different in character to that observed for most three-dimensional materials.

A Comparison Of Developmental Sentence Scores And Ratings Of Intelligibility, Julie O'Harrow Karnstein

Dissertations and Theses

Speech intelligibility is the term used to describe the degree to which an individual speaker is understood by both familiar and unfamiliar listeners. There are many factors that influence an individual's intelligibility, including (but not limited to) variations in phonology, grammar, rate of speech, and vocal features. Most research has focused on the articulation and phonological influences that impact speech intelligibility. Perhaps for this reason, treatment methods for improving speech intelligibility generally have targeted an individual's phonological production skills. Additional research is necessary to understand more about each of the areas of language production that may be influencing intelligibility. This …

Effects Of Language Interpretation Services On Medical Visit Patterns Of Patients With Limited English Proficiency, Anita Marie Kay

Dissertations and Theses

Due largely to immigration, a growing proportion of the U.S. population does not speak English well enough to communicate with medical providers. Many research studies have described ways in which language differences can compromise health care quality and access for language minority groups, but professional interpreter services are rarely provided due to costs of services and to increasing cultural and linguistic diversity among patients with limited English proficiency (LEP). Some researchers have argued that costs of interpreter services could be offset through enabling LEP patients to maintain better health and use health services more cost-effectively, such as obtaining care in …

Voices Of Solitude In Creativity, Rebecca Jane Carpenter

Dissertations and Theses

Solitude is a philosophy, a state of mind, and a lost art in today's frantic world. Evolving from the Latin root word "solus" which means "alone," it is a concept which carries an aura of mystery, because it moves at the pace of reflection and focuses on the wonder of the present moment. Much of society views solitude with distrust, fear, or even contempt as it counters the current trends of perpetual activity, technological domination, and instant gratification.

This essay explores the author's three-way encounter with the richly intricate nature of solitude, to pursue an intuitive belief in its significant …

Effects Of Adapted Storybooks On Vocabulary Acquisition Of Children Who Have A Severe Speech Impairment (Ssi), Wendy Ann Peterson

Dissertations and Theses

Research has shown that children who are typically developing have the ability to rapidly learn (fast map) and receptively identify novel vocabulary words presented in the context of storybooks. It has also been shown that repeated exposure to the stories increases the amount of information, or the number of vocabulary words, acquired by the child. Furthermore, studies have shown that children learn more when they are actively rather than passively involved in the learning process. However, little is known about how children who have a severe speech impairment (SSI) fast map new vocabulary in storybook reading contexts, or how active …

Lava And Ice Interaction At Stratovolcanoes: Use Of Characteristic Features To Determine Past Glacial Extents And Future Volcanic Hazards, David T. Lescinsky, Jonathan H. Fink

Geology Faculty Publications and Presentations

Structures resulting from lava and ice interaction are common at glaciated stratovolcanoes. During summit eruptions at stratovolcanoes, meltwater is produced and travels freely down steep slopes and thin permeable valley glaciers, eroding the ice and enlarging preexisting glacial drainages. As a result, in this environment have produced few catastrophic floods. Lava flowing into the open channels and voids in the glaciers becomes confined and grows thicker, filling the available space and producing steep-sided bodies with smooth, bulbous contact surfaces. Quenching of lava against ice or by water forms small-scale features such as tensional fractures and glass. As the amount of …

Dependence Among Spacings, Baha-Eldin Khaledi, Subhash C. Kochar

Mathematics and Statistics Faculty Publications and Presentations

In this paper, we study the dependence properties of spacings. It is proved that if X₁,..., X_n are exchangeable random variables which are TP₂ in pairs and their joint density is log-convex in each argument, then the spacings are MTP₂ dependent. Next, we consider the case of independent but nonhomogeneous exponential random variables. It is shown that in this case, in general, the spacings are not MTP₂ dependent. However, in the case of a single outlier when all except one parameters are equal, the spacings are shown to be MTP₂ dependent and, hence, …

The Cracker Patch Choice: An Analysis Of Post Hoc Security Techniques, Crispin Cowan, Heather Hinton, Calton Pu, Jonathan Walpole

Computer Science Faculty Publications and Presentations

It has long been known that security is easiest to achieve when it is designed in from the start. Unfortunately, it has also become evident that systems built with security as a priority are rarely selected for wide spread deployment, because most consumers choose features, convenience, and performance over security. Thus security officers are often denied the option of choosing a truly secure solution, and instead must choose among a variety of post hoc security adaptations. We classify security enhancing methods, and compare and contrast these methods in terms of their effectiveness vs. cost of deployment. Our analysis provides practitioners …

Language Attitudes And Academic Achievement: A Study Of Mexican Immigrant Esl Students In The Northwest, Julie Ann Cheshire

Dissertations and Theses

As the population of Mexican immigrant learners continues to increase in the Northwest, an understanding of the cultural, social and psychological realities of these students' lives becomes an ever more important issue for professional language educators, classroom teachers, and school administrators. Our understanding of the needs of these learners will have an important effect on how prepared they are to participate in academic situations and community life.

The purpose of this study was to examine the relationship between language attitudes and ESL learning among young adult Mexican-immigrant learners in one community education program in the Northwest. Learners' values and beliefs …

Contingencies Governing The Production Of Fricatives, Affricates, And Liquids In Babbling, Christina E. Gildersleeve-Neumann, Barbara L. Davis, Peter F. Macneilage

Speech and Hearing Sciences Faculty Publications and Presentations

Studies of early-developing consonants (stops, nasals, and glides) in babbling have shown that most of the variance in consonants and their associated vowels, both within and between syllables, is due to a "frame" produced by mandibular oscillation, with very little active contribution from intrasyllabic or intersyllabic tongue movements. In a study of four babbling infants, the prediction that this apparently basic "frame dominance" would also apply to late-developing consonants (fricatives, affricates, and liquids) was tested. With minor exceptions, confirming evidence for both the predicted intrasyllabic and intersyllabic patterns was obtained. Results provide further evidence for the frame dominance conception, but …
