Places For Races: The White Supremacist Movement Imagines U.S. Geography, Barbara Perry, Randy Blazak

Sociology Faculty Publications and Presentations

Increasingly, scholars are acknowledging that racial and other forms of animus assume a spatial dimension. Not only does intercultural hostility take different forms depending on location, but so, too, does the concomitant bias-motivated violence imply “places for races.” The very intent and motive of hate crimes are grounded in the perceived need of perpetrators to defend carefully crafted boundaries. While these boundaries are largely cultural, they may also take on a real, physical form, at least from the perpetrator’s perspective. Nowhere is this more evident than in the geographical imagination of the White Supremacist movement. This paper will trace the …

Mixing Layer Dynamics In Separated Flow Over An Estuarine Sill With Variable Stratification, Stefan A. Talke, Alexander R. Horner-Devine, C. Chris Chickadel

Civil and Environmental Engineering Faculty Publications and Presentations

We investigate the generation of a mixing layer in the separated flow behind an estuarine sill (height H ∼ 4 m) in the Snohomish River, Washington as part of a larger investigation of coherent structures using remote and in situ sensing. During increasing ebb flows the depth d and stratification decrease and a region of sheared flow characterized by elevated production of turbulent kinetic energy develops. Profiles of velocity and acoustic backscatter exhibit coherent fluctuations of order 0.1 Hz and are used to define the boundaries of the mixing layer. Variations in the mixing layer width and its embedded coherent …

Empirical Observation Of The Impact Of Traffic Oscillations On Freeway Safety, Christopher M. Monsere, Soyoung Ahn

TREC Final Reports

Traffic oscillations are typical features of congested traffic flow that are characterized by recurring decelerations followed by accelerations (stop-and-go driving). The negative environmental impacts of these oscillations are widely accepted, but their impact on traffic safety has been debated. This report describes the impact of freeway traffic oscillations on traffic safety. This study employs a matched case-control design using high resolution traffic and crash data from a freeway segment. Traffic conditions prior to each crash were taken as cases, while traffic conditions during the same periods on days without crashes were taken as controls. These were also matched by presence …

Application Of Cuda In The Boolean Domain For The Unate Covering Problem, Eric Paul, Bernd Steinbach, Marek Perkowski

Electrical and Computer Engineering Faculty Publications and Presentations

NVIDIA’s Compute Unified Device Architecture (CUDA) is a relatively-recent development that allows to realize very fast algorithms for several Constraint Satisfaction and Computer Aided Design tasks. In this paper we present an approach to use Graphics Processing Units (GPU) and CUDA for solving Unate Covering Problem, a practical problem related to SAT. In particular we present a CUDA-enabled Petrick Function Minimizer. We compare the performance of a pipeline-processor (CPU) and a parallel processor (GPU) implementation of the matrix-multiplication method for solving unate covering problems.

Virus Silicification Under Simulated Hot Spring Conditions, James R. Laidler, Kenneth M. Stedman

Biology Faculty Publications and Presentations

Silicification of organisms in silica-depositing environments can impact both their ecology and their presence in the fossil record. Although microbes have been silicified under laboratory and environmental conditions, viruses have not. Bacteriophage T4 was successfully silicified under laboratory conditions that closely simulated those found in silica-depositing hot springs. Virus morphology was maintained, and a clear elemental signature of phosphorus was detected by energy-dispersive X-ray spectrophotometry (EDS).

Public service applications of QR codes are examined and the use of QR codes in Japan is discussed.

The One-Pager: A Practical Policy Advocacy Tool For Translating Community-Based Participatory Research Into Action, Betty T. Izumi, Amy J. Schulz, Barbara A. Isreal, Angela G. Reyes, Jenifer Martin, Richard L. Lichtenstein, Christine Wilson, Sharon L. Sand

Community Health Faculty Publications and Presentations

The multiple and diverse perspectives, skills, and experiences inherent in community–academic partnerships make them uniquely positioned to educate policy makers and advocate for health equity. Effective communication tools are critical to successfully engage in the policy-making process. Yet few resources emphasize the development and use of practical tools for translating community-based participatory research (CBPR) findings into action. The purpose of this article is to describe a CBPR process for developing and using a one-page summary, or “one-pager,” of research findings and their policy implications. This article draws on the experience of the Healthy Environments Partnership (HEP), a community–academic partnership in …

Oregon Freight Data Mart, Miguel A. Figliozzi, Robert Bertini

TREC Final Reports

Increasing freight volumes are adding pressure to the Oregon transportation system. Monitoring the performance of the transportation system and freight movements is essential to guarantee the economic development of the region, the efficient allocation of resources, and the quality of life of all Oregonians. Freight data is expensive to collect and maintain. Confidentiality issues, the size of the datasets, and the complexity of freight movements are barriers that preclude the easy access and analysis of freight data. Data accessibility and integration is essential to ensure successful freight planning and consistency across regional partner agencies and planning organizations. In relation to …

Symmetries Of The Central Vestibular System: Forming Movements For Gravity And A Three-Dimensional World, Gin Mccollum, Douglas Hanes

Mathematics and Statistics Faculty Publications and Presentations

Intrinsic dynamics of the central vestibular system (CVS) appear to be at least partly determined by the symmetries of its connections. The CVS contributes to whole-body functions such as upright balance and maintenance of gaze direction. These functions coordinate disparate senses (visual, inertial, somatosensory, auditory) and body movements (leg, trunk, head/neck, eye). They are also unified by geometric conditions. Symmetry groups have been found to structure experimentally-recorded pathways of the central vestibular system. When related to geometric conditions in three-dimensional physical space, these symmetry groups make sense as a logical foundation for sensorimotor coordination.

Image Of The Teacher In Educational Leadership, William A. Parnell

Education Faculty Publications and Presentations

Is the early childhood teacher a babysitter and the banker of knowledge lling empty-headed children with meaningless information? Or, is the teacher of young children a facilitator, guide and co-learner at the round-table of learning with competent children and educational community participants? Ex- amining teaching and learning, organizational leadership, politics and policy, and educational research, this paper explores the image of the teacher as a theoretical discussion in educational leadership with a fundamental question: How can teaching and learning, organizational leadership, politics and policy, and educational research inform and bolster the image of the early childhood teacher? Solutions are suggested …

Non-­Native Invasive Aquatic Plant And Mussel Survey Of Six Umpqua National Forest Area Lakes, Mark Sytsma, Rich Miller, Rupa Shrestha

Center for Lakes and Reservoirs Publications and Presentations

Six lakes and ponds located within or near the Umpqua National Forest were surveyed for non-­native aquatic plants and mussels during August, 2009. A diverse assemblage of native plants was identified along with one possible non-­native aquatic plant hybrid in Herberts Pond. The possible hybrid between the non-­native species Myriophyllum spicatum and the native species M. sibiricum requires genetic analysis for identification. Water chemistry is suitable for the establishment of invasive mussels in Buckeye Lake; however, no zebra or quagga mussel veligers were detected in any of the lakes.

Black And White And Read All Over: Print, Profit, And Passion - An Interview With Peter Bhatia, Ben Lundin

Institute of Metropolitan Studies Publications

Few industries appear as precarious in today’s economy as newspapers. Once the main source of information for millions of people, printed papers now have to compete with a variety of alternative forms of information gathering and reporting. The ink-stained wretches of yore now lock horns with anonymous bloggers, pompadoured TV anchors on 24-hour news channels, YouTube, and social media for the attention of a fickle public. Among the threatened giants of the old media is The Oregonian, one of the state’s oldest businesses. We sent Ben Lundin, an awardwinning freelance journalist who worked as a staff writer for three Louisiana …

Political Science Faculty Publications and Presentations

This paper provides an overview of the authors' recent extension of Ronald Inglehart's World Values Survey (WVS) in Cyprus. Whereas the WVS is in its fifth wave of study (Inglehart et al., 1981, 1990, 1995, 2000, and 2006-2007), Cyprus iS included for the first time. Currently, the WVS comprises 99 counrnes around the world and is designed to enable the most comprehensive cross-national comparison of values and norms on a wide range of topICS and to monitor changes in values and attitudes across the globe. The comprehensive survey of Greek and Turkish Cypriots' attitudes, values, and beliefs will certainly enrich …

Tryin' To Get My Mojo Workin', Emily Ford

Library Faculty and Staff Publications and Presentations

The article discusses the reasons why librarians in the U.S. get burned out in their jobs and lose their librarian mojo. It states that librarians are dependent on systems which make them prone to systems failure while most libraries rely on tools and technologies instead of their skills and subsequently lose their mojo. It suggests to attend the American Library Association's (ALA) annual meeting and meet other librarians and get inspired about librarianship.

Comparing Discrete Simulation And System Dynamics: Modeling An Anti-Insurgency Influence Operation, Wayne Wakeland, Una E. Medina

Complex Systems Faculty Publications and Presentations

This paper contrasts the tradeoffs of modeling the same dynamic problem at a micro scale and at a macro scale of analysis: discrete system simulation (DS) versus continuous system simulation or system dynamics (SD). Both are employed to model the influence of entertainment education on terrorist system decay, with implications for field application. Each method optimizes different design, scope/scale, data availability/accuracy, parameter settings, and system sensitivities. Whether the research served by the computer model is applied or theoretical, DS tends to be useful for understand low-level individual unit/step influences on system change over time, whereas SD tends to shine when …

Investigation Of The Sources And Sinks Of Atmospheric Methane, Christopher Lee Butenhoff

Dissertations and Theses

The work presented here represents a number of independent studies that investigated various components of the CH₄ budget, namely the sources and sinks. We used a chemical-tracer model and created unique long-term time series of atmospheric CH₄, carbon monoxide (CO), molecular hydrogen (H₂), and methylchloroform (CH₃CCl₃) measurements at marine background air to derive histories of atmospheric hydroxyl radical (OH) - the main chemical oxidant of CH₄, biomass burning - an important source of CH₄ in the tropics, and emissions of CH₄ from rice paddies - one of …

Beyul Khumbu: Sherpa Constructions Of A Sacred Landscape, Lindsay Ann Skog

Dissertations and Theses

Khumbu, part of Sagarmatha (Mt. Everest) National Park in eastern Nepal and an UNESCO World Heritage site, is home to the Sherpa people, ethnic Tibetan Buddhists who migrated to the region more than 500 years ago. Sherpas animate the landscape with localized water, tree, rock, and land spirits, identify sacred mountains, mainly associated with the Bönpo and Tibetan yullha traditions, and some view the landscape as a beyul, a sacred place and hidden valley protecting Buddhist people and beliefs in times of turmoil and need. These beliefs protect the natural environment through religious practices and taboos against environmentally harmful …

The training sought to increase teachers’ understanding of ecology and qualitative conceptual models through immersion in field research and partnerships with local scientists and natural resource managers. Ecological knowledge was measured by comparing pre and post qualitative conceptual models, which were scored with a rubric and analyzed using the Wilcoxon Signed Ranks Test. Classroom implementation of an inquiry-based ecological research project was expected of participants. …

Innovation, Markets, And Evolution, Mitch Green

Economics Undergraduate Honors Theses

This paper approaches innovation from an evolutionary perspective. Literature spanning a broad range of traditions in economics is considered, to include Institutionalist, Schumpeterian, post-Keynesian, and growth theorists. Key systemic changes are examined in the context of prevailing technological and social institutions. It is argued that expectation-fixing effects such as path-dependence in investment and innovation provide structure to a social network of market institutions that seek to validate money contracts. The institution of money is considered as a center of power in the system and affects the course of innovation. Money as the unit of account becomes the object of …
