Red Signal Countdown Timers (RSCTs) are devices placed at intersections to inform drivers of the time remaining on a red indication before it turns green, typically to improve intersection efficiency. This study examines the visual attention of Oregon drivers to circular red (CR) indications with RSCTs as compared to standard...
The Manual on Uniform Traffic Control Devices prohibits positioning a bike lane right-adjacent to a vehicle turn-only lane to mitigate the potential for right-hook crashes. However, it provides no specific guidance on positioning with respect to bus-only lanes. This thesis describes a before/after safety evaluation of bike lanes positioned left...
Background: Decades of research indicate that physical
activity is an important behavior for health promotion and
disease prevention. Despite dissemination of these
research findings, many American adults are sedentary. The
rates for sedentary behavior vary by race/ethnicity and
gender. Women and adults from minority groups are most
likely to be...
The purpose of this study was to look at occupant satisfaction with Kelley Engineering Center, a LEED registered building. Results from a post-occupancy evaluation of Kelley conducted in spring 2006 were compared to those from a pre-occupancy survey of occupants in non-green buildings disseminated in spring 2005. The results showed...
Shotgun metagenomic DNA sequencing is a widely applicable tool for characterizing the functions that are encoded by microbial communities. Several bioinformatic tools can be used to functionally annotate metagenomes, allowing researchers to draw inferences about the functional potential of the community and to identify putative functional biomarkers. However, little is...
This report includes the evaluation findings from a survey of the alumni of the L'SPACE program. Results from the alumni survey show the program has significantly impacted its participants and prepared them to be effective in the workforce. The alumni had overwhelmingly positive responses about the program and offered insights...
This paper examines the U.S. meat demand impacts of the announced outbreaks of bovine spongiform encephalopathy (BSE) and avian influenza (AI). Findings indicate that beef and chicken demand was negatively affected by BSE and AI disease outbreaks. Specifically, in the short run, U.S. consumers shift demand due to both outbreaks...
The grape rust mite [Calepitrimerus vitis (Acari: Eriophyidae)] is an important pest of grapevines (Vitis sp.) in grape-growing regions around the world. A rapid method for extracting eriophyoid mites was adapted from earlier studies to provide integrated pest management (IPM) consultants and commercial growers with a practical, efficient, and reliable...
Large shifts in species ranges have been predicted under future climate scenarios based primarily on niche-based species distribution models. However, the mechanisms that would cause such shifts are uncertain. Natural and anthropogenic fires have shaped the distributions of many plant species, but their effects have seldom been included in future...
