Oh, What A Tangled Web-Site We Weave When First We Practice, Elizabeth Reynolds, James Reynolds

Northwest Journal of Teacher Education

Current emphases on computer technology have prompted a naive desire to use whatever is new regardless of its appropriateness to educational outcomes. Use of College level Web-based instruction has unearthed a variety of problems: misapplication of software, misplaced attempts to adapt traditional instruction to the Web, lack of teacher support, access and time difficulties, financial barriers, spatial/gender differences, and counterproductive approaches to learning that are unsystematic and independent versus organized, social, and cultural. The present study examined technological barriers to college student's achievement as well as student preferences regarding an optional Web-based ancillary designed to promote student achievement in an …

Developing Linguistic Literacy: Perspectives From Corpus Linguistics And Multi-Dimensional Analysis, Douglas Biber, Randi Reppen, Susan M. Conrad

Applied Linguistics Faculty Publications and Presentations

In their conceptual framework for linguistic literacy development, Ravid & Tolchinsky synthesize research studies from several perspectives. One of these is corpus-based research, which has been used for several large-scale research studies of spoken and written registers over the past 20 years. In this approach, a large, principled collection of natural texts (a 'corpus') is analysed using computational and interactive techniques, to identify the salient linguistic characteristics of each register or text variety. Three characteristics of corpus-based analysis are particularly important (see Biber, Conrad & Reppen 1998):(1) a special concern for the representativeness of the text sample being analysed, and …

Watershed Solutions: Collaborative Problem Solving For States And Communities, National Policy Consensus Center

National Policy Consensus Center Publications

In July 2002, the National Policy Consensus Center (NPCC) hosted a colloquium for people involved in watershed collaborations, academics, and other experts from government and non-profit organizations. Its aim was to identify lessons learned from successful watershed initiatives, and to develop recommendations for governors and other state officials on ways to enhance the use and effectiveness of watershed partnerships. This report is an outgrowth of that conference.

Studies on watershed collaborations are beginning to identify what makes them successful and what some of the barriers are to greater success. For example, contrary to the fears of some observers, successful collaborations …

Summarizing Concepts About Teacher Education, Learning And Neuroscience, Terry Armstrong, Teresa J. Kennedy, Porter Coggins

Northwest Journal of Teacher Education

Despite on-going reform. teacher education today is virtually unchanged from models used in the 1920s. The achievements of the past century however have been remarkable in every way. Neuroscience records and the human genome project hold the prospect of truly expanded conceptualizations for teacher educators. This article summarizes concepts relating to the human cerebrum that speak to individual uniqueness derived from neuroscience research of the past several decades. Five areas of investigation are noted that could provide the theoretical underpinning for teacher education collaboration with neuroscientists. Neuroscience theorists are identified in anticipation that their work may provide insights to teacher …

Applying The Constructivist Framework To Elementary School Social Studies: Benefits For Young Learners And Preservice Teachers, Nancy P. Gallavan

Northwest Journal of Teacher Education

The constructivist framework provides elementary school teachers with pedagogical guidance and professional support particularly effective for teaching and learning social studies benefiting both their young learners and their preservice teachers. Research conducted with approximately 100 elementary school teachers produced three key conditions for applying the constructivist framework competently to social studies education. Findings from this research revealed that elementary school teachers believe that foremost they must he cognizant of and proficient in their: (1) knowledge, skills, and attitudes of social studies content and purposes, (2) understanding for developing social studies curriculum and methods for communicating the social studies effectively both …

Inclusive Child Care: Challenges And Strategies, Eileen M. Brennan, Elizabeth Haran Caplan, Shane Ama, Jennifer R. Bradley, Olivia Warfield

School of Social Work Faculty Publications and Presentations

Responding to the need for research regarding models of inclusion in child care, the Research and Training Center on Family Support and Children's Mental Health is in the process of conducting a series of studies aimed at guiding the design and implementation of inclusive child care policies and programs. In the course of previous research studies, our research team found that there did exist quality programs and family care arrangements that successfully included children with emotional or behavioral challenges in child care settings (Brennan, Rosenzweig, Ogilvie, Wuest, & Ward, 2001). Our goal was to learn more about the provider and …

Thread Transparency In Information Flow Middleware, Rainer Koster, Andrew P. Black, Jie Huang, Jonathan Walpole, Calton Pu

Computer Science Faculty Publications and Presentations

Existing middleware is based on control-flow centric interaction models such as remote method invocations, poorly matching the structure of applications that process continuous information flows. Difficulties cultiesin building this kind of application on conventional platforms include flow-specific concurrency and timing requirements, necessitating explicit management of threads, synchronization, and timing by the application programmer. We propose Infopipes as a high-level abstraction for information flows, and we are developing a middleware framework that supports this abstraction. Infopipes transparently handle complexities associated with control flow and multi-threading. From high-level configuration descriptions the platform determines what parts of a pipeline require separate threads or …

A Comparison Of Evolutionary And Coevolutionary Search, Ludo Pagie, Melanie Mitchell

Computer Science Faculty Publications and Presentations

Previous work on coevolutionary search has demonstrated both successful and unsuccessful applications. As a step in explaining what factors lead to success or failure, we present a comparative study of an evolutionary and a coevolutionary search model. In the latter model, strategies for solving a problem coevolve with training cases. We find that the coevolutionary model has a relatively large efficacy: 86 out of 100 (86%) of the simulations produce high quality strategies. In contrast, the evolutionary model has a very low efficacy: a high quality strategy is found in only two out of 100 runs (2%). We show that …

Term Trees In Application To An Effective And Efficient Atpg For And–Exor And And–Or Circuits, Lech Jozwiak, Aleksander Ślusarczyk, Marek Perkowski

Electrical and Computer Engineering Faculty Publications and Presentations

A compact data representation, in which the typically required operations are performed rapidly, and effective and efficient algorithms that work on these representations are the essential elements of a successful CAD tool. The objective of this paper is to present a new data representation—term trees (TTs)—and to discuss its application for an effective and efficient structural automatic test-pattern generation (ATPG). Term trees are decision diagrams similar to BDDs that are particularly suitable for structure representation of AND–OR and AND–EXOR circuits. In the paper, a flexible algorithm for minimum term-tree construction is discussed and an effective and efficient algorithm for ATPG …

Models Of Inclusion: Standing At The Cross Roads. Building Inclusive Child Care Through Child Care Development Funds, Eileen M. Brennan, Shane Ama, Elizabeth Haran Caplan, Olivia Warfield, Sherry Archer

School of Social Work Faculty Publications and Presentations

The passage of the Americans with Disabilities Act (ADA) in 1990 has produced a growing recognition that children with disabilities have the same rights as other children to participate in community-based child care settings (Whitney, Grozinsky, & Poppe, 1999). But even a legal mandate is not sufficient to guarantee access to realistic and suitable child care options for every family, particularly those having children with emotional or behavioral disorders (National Child Care Information Center [NCCIC], 1997). The presentation addressed governmental policy and planning efforts to include children with emotional or behavioral challenges in settings with typically developing children. Particularly, presenters …

Hitting The Line Hard : The Height Of The Social Hygiene Movement In Oregon, 1911-1918, Jodi Hammond

Dissertations and Theses

This thesis provides the history of a grass-roots educational campaign to educate the public of the dangers of venereal disease undertaken by reformers within the Oregon Social Hygiene Society. It recounts the forces which caused prominent citizens of the state to take up the hygiene society's cause and bring the organization to national prominence for state-wide educational work. The thesis considers the inherent tensions between purity and sanitary-based reformers within the hygiene movement. It demonstrates how reformers were able to put aside conflicting views for a time and unite to pursue educational goals. The thesis provides a blueprint of a …

High Frequency Of Extra-Pair Paternity In Eastern Kingbirds, Diane L. Rowe, Michael T. Murphy, Robert C. Fleischer, Paul G. Wolf

Biology Faculty Publications and Presentations

Genetic parentage in the socially monogamous and territorial Eastern Kingbird( Tyrannust tyrannus) was examined in a central New York population by multilocus DNA fingerprinting. Extra-pair young were identified in 60% (12 of 20) of nests. Of the 64 nestlings profiled, 42% were sired by extra-pair males, but no cases of conspecific brood parasitism were detected. These results are markedly different from a previous electrophoretic study of the same species in a Michigan population, which reported 39% of nestlings were unrelated to one (typically the mother, quasiparasitismo)r both (conspecificb roodp arasitism) of the putative parents. In the New York population, extra-pairp …

An Evaluation Of Families And Service Providers Participating In Participatory Action Research Related To Self-Determination In Young Children With Disabilities, Kristen L. Kozlowski

Dissertations and Theses

The concept of self-determination or "acting as the primary casual agent in one's life and making choices and decisions regarding one's quality of life free from undue external influence or interference" (Wehmeyer, 1996, p.24) has long been a focus of educating adults with disabilities. Recently, researchers and educators have begun to examine teaching foundational skills of self-determination to young children with disabilities. It is important to evaluate programs and methodologies that are said to enhance self-determination in order to ensure their efficacy. Research has examined self-determination programs involving adults and older children, however to date there have been few studies …

Engineering and Technology Management Student Projects

The Internet has seen its share of success and failures as businesses try to understand how this new medium is going to be used in the 21st century. The eBay corporation has defined itself as not only a player on the Internet but as founders of a new business concept: online bidding and selling for the masses.

Being first to market gives eBay some of the key strengths to make the most of this new medium. The key success factors such as a large customer base and a compelling environment online are allowing eBay to be profitable and be seen …

Focal Point, Volume 15 Number 02, Portland State University. Regional Research Institute

Research and Training Center - Focal Point

This issue of Focal Point begins from the idea that enrichments, far from being frivolous, are instead essential. The joy and meaningfulness which enrichments provide make a direct, positive contribution to quality of life. What is more, enriching experiences add to our reserves of strength and purpose, and these reserves in turn enable us to adapt, cope, recover and even thrive in the face of challenges and stresses. Specifically, this issue of Focal Point looks at research related to sources of enrichment, and at innovative programs that promote enrichment and achieve positive outcomes for children with emotional and behavioral challenges, …

Transgenic Crops And The Environment: Missing Markets And Public Roles, David E. Ervin, Sandra S. Batie

Economics Faculty Publications and Presentations

The rapidity of change has left scant opportunity for investigation of the consequences of adoption of transgenic crops on long-term ecosystem or economic system functioning. Economic theory suggests that, if the "Biotechnology Revolution" is left to market forces alone, there will be neglected public goods. Theory and limited empirical evidence suggests that there are significant incentives for private firms to discount and neglect certain environmental impacts and to develop products that meet mainly the needs of those able and willing to pay. Negative distributional impacts on rural societies and economies will not normally enter the private calculus nor will the …

Reifying Communication At The Application Level, Andrew P. Black, Jie Huang, Jonathan Walpole

Computer Science Faculty Publications and Presentations

Middleware, from the earliest RPC systems to recent Object-Oriented Remote Message Sending (RMS) systems such as Java RMI and CORBA, claims transparency as one of its main attributes. Coulouris et al. define transparency as “the concealment from the … application programmer of the separation of components in a distributed system.” They go on to identify eight different kinds of transparency.

We considered titling this paper “Transparency Considered Harmful”, but that title is misleading because it implies that all kinds of transparency are bad. This is not our view. Rather, we believe that the choice of which transparencies should be offered …

A Dissertation On African American Male Youth Violence: "Trying To Kill The Part Of You That Isn’T Loved", Joy Degruy Leary

Dissertations and Theses

This dissertation is based on Sociocultural Theory, Social Learning Theory and Trauma Theory, as well as a new theoretical framework (Post Traumatic Slave Syndrome) which takes into account multigenerational trauma. Five research questions involving independent variables believed to predict violent behavior in African American male youth were investigated. The first three questions addressed stressors experienced by African Americans: violence witnessing, violence victimization, and daily urban hassles. The fourth and fifth questions concerned the sociocultural characteristics of racial socialization and prosocial attitudes toward respect. Participants were 200 African American male youth residing in inner Northeast Portland, Oregon who were recruited from …
