The epistemic practices that make up engineering are poorly understood and there is a lack of empirical research on this topic. Characterizing the epistemic practices of engineering students, faculty, and professionals is critical to creating effective curriculum that aids in developing student’s epistemic practices. Doing so allows us to better...
Traditional public health bacterial indicators of water quality and the Biolog® system were evaluated to compare their response to other indicators of stream condition with the state of Oregon and between ecoregions (Coast Range, Willamette Valley, Cascades, and Eastern Oregon). Forty-three randomly selected Oregon rivers were sampled during the summer...
Denitrifying bioreactors are an edge-of-field treatment technology particularly well suited for nitrate removal from subsurface (tile) drainage effluent of agricultural lands. The effectiveness of a proposed denitrifying bioreactor is site-specific and depends upon the complicated interplay of field and environmental parameters controlling discharge events, nitrate concentrations, subsurface temperatures, dissolved oxygen...
Image classification is a difficult problem, often requiring large training sets to get satisfactory results. However this is a task that humans perform very well, and incorporating user feedback into these learning algorithms could help reduce the dependency on large amounts of labeled training data. This process has already been...
Main Street USA in Southern California’s Disneyland theme park is often described as nostalgic. However, previous research on this subject has failed to identify what elements actually make Main Street USA nostalgic as well as determine why Disney uses this nostalgia to influence park guests. In order to respond to...
This study, conducted with the cooperation of the Oregon Comprehensive
Health Planning Agency, Salem, had a threefold purpose:
(1) to identify the role of the physician's assistant (PA) in Oregon,
(2) to provide substantive data for recommendations regarding changes
in PA licensure, and (3) to provide information which may be...
Architects and engineers are two key types of design professionals who influence the use of wood products in construction. Eighty to ninety percent by volume of all residential structures in the U.S. are wood (Gupta, 2005). In 2010, the non-residential market was made up by 10% wood, 60% steel and...
Anne Frances Wysocki, a scholar in the field of new media and composition studies, has published many articles, book chapters, a textbook, and is a major contributor to a multi-authored collection titled Writing New Media: Theory and Applications for Expanding the Teaching of Composition. This thesis considers the five openings...
Forest disturbances, such as wildfires, pine beetle outbreaks, and floods are important features of many landscapes and ecosystems. Many disturbances are increasing in size, frequency, and intensity due to changing climates and land management decisions. The changing ecological and aesthetic conditions following a disturbance can lead to negative short- and...
Heparin was modified and immobilized to surface-activated silica surfaces using two different reaction schemes. End-aminated heparin was reacted with 2-iminothiolane to produce free thiol groups at the terminal ends of the heparin chains. The end-thiolated heparin was immobilized by reaction with a pyridyl disulfide activated poly[ethylene oxide]-poly[propylene oxide]-poly[ethylene oxide] triblock...
