The purpose of this study was to better understand the perceptions of employers and graduates regarding the applied baccalaureate degree when conferred by community colleges. By better understanding the perceptions of employers and graduates, community colleges considering offering applied baccalaureate degrees will have some context within which to begin communicating...
In 2007, the Oregon Wave Energy Trust (OWET) put out a request for proposals to begin to discover answers to many of the environmental and human dimensions questions. A multidisciplinary group of social scientists – Flaxen Conway, Brent Steel, Michael Harte, and Bryan Tilt, Oregon State University – responded to...
Presented at 2009 Institutional Repositories: Disseminating, Promoting, and Preserving Scholarship Conference held September 30 at Utah State University in Logan, Utah.
As the 2009 growing season comes to a close, we prepared this newsletter to provide information on several viticulture and enology issues important to the Oregon winegrape industry. We begin with the most immediate topic of this season – wine production with Dr. James Osborne and importance of wine superstars...
This work compares the Weather Research and Forecasting (WRF) and Hadley Centre Regional Model (HadRM) simulations with the observed daily maximum and minimum temperature (Tmax and Tmin) and precipitation at Historical Climatology Network (HCN) stations over the U.S. Pacific Northwest for 2003–07. The WRF and HadRM runs were driven by...
Analytical methods capable of trace measurement of semi-volatile organic
compounds (SOCs) are necessary to assess the exposure of tadpoles to contaminants as a
result of long-range and regional atmospheric transport and deposition. The following
study compares the results of two analytical methods, one using pressurized liquid
extraction (PLE) and the...
A reexamination of turbulence dissipation measurements from the equatorial Pacific shows that the turbulence diffusivities are not a simple function of the gradient Richardson number. A widely used mixing scheme, the K-profile parameterization, overpredicts the turbulent vertical heat flux by roughly a factor of 4 in the stably stratified region...
Field trials in four distinct agricultural soils were conducted to examine changes to total recoverable and labile soil Cd and Ni concentrations with applications of commercial phosphate fertilizers. The edible portion of wheat and potato crops grown at the field plots were analyzed for recoverable Cd and Ni. Total recoverable...
The OSU Perspective was developed to provide assessment and other information about our students and programs. We hope that by making this information available to OSU faculty and staff, we can stimulate conversation that helps to keep students and student learning at our core.
The Perspective is published quarterly both...
Apex predators have experienced catastrophic declines throughout the world as a result of human persecution and habitat loss. These collapses in
top predator populations are commonly associated with dramatic increases in the abundance of smaller predators. Known as “mesopredator release,”
this trophic interaction has been recorded across a range of...

"Infestations of the spotted wing Drosophila fly (Diptera: Drosophilidae), an exotic pest, have been found in Oregon fruits in 13 counties. Of the 3,000 species of Drosophila, commonly known as vinegar flies, approximately 175 are known in North America. Two of these known species have been found to be harmful...

It is widely recognized that the risks associated to both patients and medical personnel during therapeutic interventional procedures are greater than for other diagnostic studies due to the increased number, and complexity of the examinations resulting in increased radiation exposure. This report documents the practices of seven interventional radiologists at...
Engineered capillary barriers typically consist of two layers of granular materials designed so that the contrast in sediment hydrologic properties and sloping interface retains infiltrating water in the upper layer. We report here on the results of two bench-top capillary barrier experiments, and associated modeling. These experiments were conducted to...
The use of autonomous robots in complex exploration tasks is rapidly increasing. Indeed, robots can provide speed and cost effectiveness in many tasks, as well as allow operation in environments that are hostile to humans. In this dissertation we: 1) provide two adaptive navigation algorithms; 2) develop a coordination mechanism;...
Commercial thinning operations can result in damage to residual stems. A literature review revealed that little was known about the effects of residual logging wounds with regard to rotation-age commercial conifers, particularly Douglas-fir. An experiment to examine fungal colonization of Douglas-fir following logging damage showed that while damage was significant...
The increasing popularity of cellular phones with integrated cameras in the
recent past has led to major improvements in its image quality. However, integration of new features, such as mobile email, video streaming, MP3 etc. tend to put the limitation on image quality as camera phone designers struggle to manage...
This qualitative study considered faith as a part of the lifespan development of adults with developmental disabilities between the ages of 30 and 67 years. Ten individuals who participated attended an adapted liturgy and/or fellowship group hosted by two Roman Catholic faith formation groups. The data were gathered through individual,...
Humans have long suffered the effects of disease causing biological agents. Today bioterrorism appears to be on the rise while at the same time global and ecological changes have resulted in the emergence of new diseases. Potential repercussions of an epidemic pose immense challenges requiring a methodical approach to align...
The purpose of this study is to explore the applicability of Collins’ (2001) Good-to-Great theory, as originally introduced for the business sector and as adapted for the social sector, to the ways a community college moved from being “good” to being
“great.” The following questions guided the research: (1) Which...
Mayweed chamomile (Anthemis cotula L.) is an annual weed in the Asteraceae family that is commonly found in fields of the Pacific Northwest. Acetolactate synthase (ALS)-inhibiting herbicides are frequently used to control a broad spectrum of weed species including mayweed chamomile. Seeds of four biotypes of mayweed chamomile (KJ, KL1,...
Monitoring the sources and fate of freshwater in the
East Greenland Current (EGC) is important, as this water
has the potential to suppress deep convection in the Nordic
and Labrador Seas if the outflow of freshwater from the
Arctic Ocean increases in response to climate change. Here,
hydrographic, oxygen isotope...
This objective of this study is to investigate the capability of nanostructured surfaces on dissipating heat flux by performing pool boiling and convective flow boiling. The generation of ultra-high heat flux from high performance electric devices has motivated a number of investigations related to advanced heat transfer especially in two-phase...
Changes in federal forest management, enactment of environmental policies, recessions and a shift to a global economy dramatically impacted counties between the 1980s and 1990s. In the 1990s, counties began experiencing a shift away from traditional natural resource extraction activities – amidst changing demographics resulting from rural restructuring taking place...
