HTLV was more common among participants living in villages distant from larger port cities and women with non-monogamous sexual partners.

Oregon's Health Insurance Coverage Holds Steady, But The State's Uninsured Rate Remains High, Jason R. Jurjevich, Jack Byerly

Publications, Reports and Presentations

Data released in August 2012 from the U.S. Census Bureau’s Small Area Health Insurance Estimates (SAHIE) program show that Oregon continues to have one of highest rates of uninsured residents in the U.S. According to Census estimates, 639,710 or 19.7 percent of Oregonians under age 65 were without health insurance coverage in 2010. For the under-65 population, Oregon’s uninsured rate ranks as the 15^th highest rate in the country.

Compared to 2009, the 2010 data show no statistically significant change in the overall uninsured rate for Oregon. Similarly, there were no statistically significant changes for Oregon between 2009 and …

Assessing The Impact Of Cluster Policies: The Case Of The Arranjos, Lucas Figal Garone, Alessandro Maffioli, Cesar M. Rodriguez, Gonzalo Vazquez Bare, Joao Alberto Denegri

Economics Faculty Publications and Presentations

This paper assesses the impact of a cluster development policy in Latin America. A Local Productive Arrangement (APL) is a cluster of firms within the same territory, operating around the same activity and maintaining ties of cooperation and learning among themselves and with other stakeholders. Using firm-level data comprising information on SMEs from Brazil for the years 2002 to 2009 we apply fixed effects, matching and reweighting methods to estimate both the direct and the indirect – i.e. spillovers – causal effect of participating in APLs on a series of SMEs’ performance indicators, including level of employment, value of exports …

Analysis Of Travel Time Reliability For Freight Corridors Connecting The Pacific Northwest, Miguel A. Figliozzi

Civil and Environmental Engineering Faculty Publications and Presentations

A new methodology and algorithms were developed to combine diverse data sources and to estimate the impacts of recurrent and non-recurrent congestion on freight movements’ reliability and delays, costs, and emissions. The results suggest that traditional traffic sensor data tend to underestimate the impacts of congestion on commercial vehicles travel times and variability. This research also shows that congestion is not only detrimental for carriers and shippers costs but also for the planet due to major increases in GHG emissions and for the local community due to large increases in NOx, PM, and other harmful pollutants.

The methodologies developed throughout …

Contextual Influences On Trip Generation, Kelly J. Clifton, Kristina Marie Currans, Christopher D. Muhs

Civil and Environmental Engineering Faculty Publications and Presentations

There is national interest in building data that expands upon the existing Institute of Transportation Engineers (ITE) trip generation rates to include sites located in a multi-modal context. Current ITE rates represent travel behavior for development in single lots and uses, primarily measured in low-density suburban areas. Despite evidence that a more compact urban form, access to transit and a greater mix of uses generates fewer and shorter vehicle trips, local governments are often compelled to use current ITE trip generation rates to evaluate transportation impacts and calculate transportation system development charges (TSDCs). This is due to: a) the expense …

System Dynamics Modeling Of Prescription Opioid Pain Reliever Abuse, Alexandra Nielsen

Systems Science Friday Noon Seminar Series

The nonmedical use of prescription opioid pain relievers and associated overdose deaths have been labeled an epidemic by the Centers of Disease Control and Prevention. While these medicines play an important role in the treatment of pain, the benefits of opioids for the treatment of pain need to be balanced against these very real risks. Alex has been working closely with Professor Wayne Wakeland, Teresa Schmidt, and Dr. Dennis McCarty (OHSU) to create a dynamic systems-level model of opioid use, abuse, and diversion in order to give context to current research in this area and to provide a better understanding …

Troublesome Concepts And Information Literacy: Investigating Threshold Concepts For Il Instruction, Amy R. Hofer, Lori Townsend, Korey Brunetti

Library Faculty and Staff Publications and Presentations

Librarians regularly encounter students who struggle to understand and apply information literacy concepts. A qualitative survey administered to information literacy practitioners asked about troublesome content and analyzed results using the threshold concepts pedagogical framework first described by Jan Meyer and Ray Land. A threshold concept transforms the learner’s view of content and helps integrate previously learned material; threshold concepts are portals that, once traversed, bring insight into how to think and act like a practitioner within a discipline. This project uses the data collected to propose seven threshold concepts for information literacy.

The Ase Research Model: A Lightning Talk, Kimberly Willson-St. Clair

Library Faculty and Staff Publications and Presentations

This PowerPoint describes the Analyze, Search, Evaluate (ASE) model for building a research strategy. This pedagogical model was field tested by Dr. Melissa Gross and Dr. Don Latham in a large, IMLS funded study of Florida college students who were targeted for remedial instruction regarding research skills and information literacy. Using this method at the Portland State University Library in research classes for freshman and international students, I have found the ASE research model to be an engaging way to organize an hour library class so that students learn an efficient and easy way to construct their research strategies.

Land Use Planning In Oregon: The Quilt And The Struggle For Scale, Ethan Seltzer

Urban Studies and Planning Faculty Publications and Presentations

The history of planning in Oregon in the latter part of the 20th century is in many respects a history of the state attempting to reassert its interests in local planning and zoning after having granted the power to plan and zone to local governments early in the 20th century. The Oregon land use planning program evolved as a means for ensuring that state interests in the use of resource land and the prevention of sprawl were carried out meaningfully through local planning and zoning. Rather than a single state plan, Oregon has instead relied on the "quilt" of local …

Hawaiian Presence At Fort Vancouver National Historic Site, Douglas C. Wilson

Anthropology Faculty Publications and Presentations

Fort Vancouver, as the colonial "Capital" of the Pacific Northwest in the 1820s-1840s, supported a multiethnic village of 600-1,000 occupants. A number of the villagers were Hawaiian men who worked in the agricultural fields and sawmills of the Hudson’s Bay Company (HBC) operations. Identification of Hawaiian residences and activities has been an important element of studies of Fort Vancouver National Historic Site, Vancouver, Washington, since the 1960s.

Kauanui calls for a "broad research agenda that accounts for Hawaiian movements in their respective contexts of conditions, periods, reasons, and desires, to allow us to better account for Hawaiian presence on the …

Body Mass Index And The Risk Of Prostate Cancer, Daniel Lee Mcgee, Carlos J. Crespo

Community Health Faculty Publications and Presentations

Background: This article presents cohort studies that use data from the National Health Information Survey from 1986 to 1994 and compares the effectiveness of Cox proportional hazards models that assume a linear relationship between body mass index (BMI) and the risk of prostate cancer with models that assume a J-shaped relationship. Methods and results: Our study found that for black males over 40 years of age, neither a linear nor a J-shaped relationship yielded a statistically significant model. With white males over 40 years, assuming a linear relationship did not yield a statistically significant model (P = 0.582). When we …

Measuring The Longitudinal Effects Of Food Carbon Footprint Training On Consumers: Knowledge, Attitudes, And Behavioral Intentions, Robin Wikoff, Gretchen N. Rainbolt, Wayne Wakeland

Complex Systems Faculty Publications and Presentations

Although the supply chains through which foods are produced, processed, and transported can have a significant impact on carbon dioxide (CO₂) emissions, consumers are largely unaware of how their food choices may impact the environment. Based on a previous related study, we hypothesized that a web-based training process could increase consumer knowledge and perhaps influence consumer behavior longitudinally. To test this, food distribution networks were modeled and analyzed to determine CO₂ footprints for a variety of foods, and a training process was designed to teach consumers about the CO₂ emissions for different types of foods that …

The Semiotic Ecology And Linguistic Complexity Of An Online Game World, Steven L. Thorne, Ingrid Fischer, Xiaofei Lu

World Languages and Literatures Faculty Publications and Presentations

Multiplayer online games form complex semiotic ecologies that include game-generated texts, player-to-player communication and collaboration, and associated websites that support in-game play. This article describes an exploratory study of the massively multiplayer online game (MMO) World of Warcraft (WoW), with specific attention to its qualities as a setting for second language (L2) use and development. This empirical study seeks to answer the following question: What is the nature of the linguistic ecology that WoW players are exposed to? Many studies have described the developmental opportunities presented by commercially available gaming environments (e.g., Gee, 2003, 2007), their value as sites of …

Is Portland Really The Place Where Young People Go To Retire? Migration Patterns Of Portland’S Young And College-Educated, 1980-2010, Jason R. Jurjevich, Greg Schrock

Publications, Reports and Presentations

For many metro areas, including Portland, being economically competitive in today’s knowledge and information economy depends on attracting and retaining young, college-­‐educated (YCE) migrants. On this indicator, Portland has been most successful: since 1980, the Portland metropolitan region has attracted college-­‐educated individuals under the age of 40 at some of the country’s highest net migration rates in good economic times and bad. Though not unique to Portland, the resiliency of Portland’s migration streams, even in periods of economic uncertainty, calls attention to an increasingly selective group of YCE migrants who appear to place greater relative value on non-­‐economic factors—from political …

Is Portland Really The Place Where Young People Go To Retire? Analyzing Labor Market Outcomes For Portland’S Young And College-Educated, Jason R. Jurjevich, Greg Schrock

Publications, Reports and Presentations

Few segments of the population are more critical to Portland’s future economic vitality than the young and college‐educated (YCE). In the last several decades the Portland metropolitan region has become a magnet for YCEs nationally, boasting one of the country’s highest net migration rates for college‐educated individuals under the age of 40, a trend that has continued in good economic times and bad. The infusion of human capital from other regions has undoubtedly been a benefit to Portland, especially given Oregon’s historically low levels of investment in higher education.

However, in recent years there has been growing concern about the …

The domestic dog offers a unique opportunity to study complex disorders similar to those seen in humans, but within the context of the much simpler genetic backgrounds of pure breeds, which represent closed populations. We performed a whole-genome search for genetic risk factors of adult-onset deafness in the Border Collie, a breed of herding dog that relies on acute hearing to perceive and respond to commands while working. Adult-onset deafness in Border Collies typically begins in early adulthood and is similar to age-related hearing loss in humans. This earlier onset has particular impact on the utility of working Border Collies …
