Assessing Soil Lead Contamination At Multiple Scales In Oakland, California: Implications For Urban Agriculture And Environmental Justice, Nathan Mcclintock Nov 2012

Assessing Soil Lead Contamination At Multiple Scales In Oakland, California: Implications For Urban Agriculture And Environmental Justice, Nathan Mcclintock

Urban Studies and Planning Faculty Publications and Presentations

As urban agriculture grows in popularity throughout North America, vacant lots, underutilized parks, and other open spaces are becoming prime targets for food production. In many post-industrial landscapes and in neighborhoods with a high density of old housing stock, the risk of lead (Pb) contamination at such sites is raising concerns. This paper evaluates the extent to which soil Pb contamination may be an obstacle to the expansion of urban agriculture in Oakland, California. Using a combination of soil sampling at 112 sites, GIS, “hot spot” analysis, and reconstructed land use histories, the research reveals that soil Pb concentrations are ...


Analysis Of Travel Time Reliability For Freight Corridors Connecting The Pacific Northwest, Miguel A. Figliozzi Nov 2012

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 Nov 2012

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 ...


Twenty-Somethings In The Classroom And Counseling Office: Understanding Emerging Adult Counseling Students, Joel A. Lane Nov 2012

Twenty-Somethings In The Classroom And Counseling Office: Understanding Emerging Adult Counseling Students, Joel A. Lane

Counselor Education Faculty Publications and Presentations

Recent trends in many counseling training programs have reflected a proliferation of students entering graduate school directly after completing an undergraduate program. This proliferation has resulted in an increase in the number of emerging adult counseling students. Emerging adulthood is the term used to describe the ages of 18-25, and is unique in that individuals in this age group identify subjectively with aspects of both adolescence and adulthood without fully identifying with either. Lacking a crystallized adult identity poses unique challenges for these students, particularly with regard to developing professional identity and self-efficacy. While many emerging adults view these challenges ...

Body Mass Index And The Risk Of Prostate Cancer, Daniel Lee Mcgee, Carlos J. Crespo Oct 2012

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 ...

Hawaiian Presence At Fort Vancouver National Historic Site, Douglas C. Wilson Oct 2012

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 ...

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

Systems Science 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 are ...


Land Use Planning In Oregon: The Quilt And The Struggle For Scale, Ethan Seltzer Oct 2012

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 ...


Troublesome Concepts And Information Literacy: Investigating Threshold Concepts For Il Instruction, Amy R. Hofer, Lori Townsend, Korey Brunetti Oct 2012

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

Library Faculty 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 Oct 2012

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

Library Faculty 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.

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 ...


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 Sep 2012

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 ...

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 ...

Homeless Encampments On Public Right-Of-Way: A Planning And Best Practices Guide, Ellen M. Bassett, Andrée Tremoulet, Allison Moe

Urban Studies and Planning Faculty Publications and Presentations

Homelessness is a societal problem. Its causes are complex, and its effects have implications for many public agencies, including those not directly responsible for providing assistance to homeless individuals. Because homeless people constantly seek safe shelter and refuges, agencies that own public land and buildings sometimes find themselves in contact with this population. Nationally, the impact of homelessness appears to represent a substantial operational challenge for state transportation agencies and Departments of Transportation (DOTs). Two online surveys?one of state DOT managers and supervisors and the other of public sector managers of highway rest areas (DOT and other state agency ...


Value Of Travel Time Reliability Part Ii: A Study Of Tradeoffs Between Travel Reliability, Congestion Mitigation Strategies And Emissions, Miguel A. Figliozzi, Alexander Y. Bigazzi Sep 2012

Value Of Travel Time Reliability Part Ii: A Study Of Tradeoffs Between Travel Reliability, Congestion Mitigation Strategies And Emissions, Miguel A. Figliozzi, Alexander Y. Bigazzi

Civil and Environmental Engineering Faculty Publications and Presentations

Capacity, demand, and vehicle based emissions reduction strategies are compared for several pollutants employing aggregate US congestion and vehicle fleet condition data. We find that congestion mitigation does not inevitably lead to reduced emissions; the net effect of mitigation depends on the balance of induced travel demand and increased vehicle efficiency that in turn depend on the pollutant, congestion level, and fleet composition. In the long run, capacity-based congestion improvements within certain speed intervals can reasonably be expected to increase emissions of CO2e, CO, and NOx through increased vehicle travel volume. Better opportunities for emissions reductions exist for HC and ...
