Seasonal emergent wetlands in the Pacific Northwest have not been regarded traditionally as fish rearing habitat, despite access to such habitat when river flows overtop riverbanks and connect to the floodplain. As a result, restoration and enhancement projects to remediate for the loss of such wetland habitat are being implemented...
A recent trend of enhancing freshwater emergent wetlands for waterfowl and other wildlife has raised concern about the effects of such measures on juvenile salmonids. We undertook this study to quantify the degree and extent of juvenile Pacific salmon Oncorhynchus spp. utilization of enhanced and unenhanced emergent wetlands within the...
An analysis and modeling method of the diagnostic characteristics of a mechanical or electromechanical system is presented. Diagnosability analysis is especially relevant given the complexities and functional interdependencies of modern-day systems, since improvements in diagnosability can lead to a reduction of a system's life-cycle costs. The diagnosis process of a...
Urban ecosystems are characterized by human disturbance and changes in the amount, types, and spatial arrangement of wildlife habitat. The relative importance of habitat and human associated variables to urban birds is unknown. In 1999, I surveyed spring bird and plant communities along 54 perennial streams
in the Portland, Oregon...
The aim of this study is to explore how women who identify as both active, believing Mormons and as feminists negotiate the contradictions between an ideology that values equality (feminism) and a religion that values patriarchy (Mormonism). Data were gathered through recorded and transcribed interviews with women who identify as...
Hop (Humulus lupulus L. var. lupulus) is grown worldwide for the production of the dried female inflorescence (strobulus), or cones, used principally for the bittering and flavoring of beer. Information is scant on the inheritance of traits of economic importance in hop, and present knowledge is based on historical data...
Hop (Humulus lupulus L.) is a perennial, dioecious species in which the female inflorescence (cones) are harvested and used in the beer-brewing process to impart bittering and/or flavoring to beer. Hop breeders have typically utilized clonal selection and hybridization to develop new cultivars. The use of genetically diverse parents for...
Hop (Humulus lupulus L.) is cultivated for the female flowers, or “cones,” which traditionally have been used as a bittering and flavoring agent in beer. Hop breeding historically relied on relatively simple selection techniques within established breeding lines. Supplementing current breeding material with new genetic sources would enhance a hop...
The Middle Fork of the John Day River (MFJD) in Northeastern Oregon contains important spawning grounds for spring Chinook and summer steelhead of the Columbia River Basin. In the summer of 2008 phase one of a river restoration project was completed which included the addition of engineered log jams (ELJs)...
Current public health guidelines for physical activity (PA) were primarily formulated using evidence collected from a series of prospective cohort epidemiological investigations that measured self-reported PA. In light of this observation, and the known discordance between self-reported and objectively-monitored PA, it remains common for researchers to assess compliance to current...
The purpose of this study was to determine the effects of a
power lifting weight training program on the dynamic strength, static
strength and body composition of college females. Thirteen college
females volunteered for the study. The subjects trained three days
per week for a total of nine weeks which...
Although public sector unionism dates back at least
to 1916, collective bargaining emerged mid-century when
President John Kennedy signed into law Executive Order
10988 which established federal policy recognizing unions
for federal employees. Today all levels of public education
have unions. In today's community college, the curriculum,
the professional background...
This internship project (Dr. Dawn Wright—Department of Geoscience) was a synthesis of several aspects of the research process. The documentation of methods consisted of: primary data collection of soil samples, geographical coordinates, georeferencing, basemap creation, laboratory machine operation, laboratory methods, laboratory quality control planning, statistical analysis, and geo-statistical analysis using...
This study examined the culture of Earth First!, an environmental
activist movement. The study was limited to two groups of Earth
First! in the Northwest, Corvallis and Eugene. The goal was to
discover what it is to be a communicatively competent member of Earth
First! The method used to address...
This study quantified the frequency of simple versus
complex races of Puccinia striiformis Westend. in mixtures
of wheat cultivars possessing different race-specific
resistance genes. A simple race of a pathogen can infect
only one component, and a complex race of the pathogen can
infect two or more components of an...
Nisin, an amphiphilic, antimicrobial peptide, has been shown to integrate into the hydrophobic inner region of poly(ethylene oxide) (PEO) brush layers; however, the presence of integrated nisin may compromise the protein repulsive character of the PEO layer. In particular, the introduction of fibrinogen to nisin-loaded brush layers has been observed...
Four experiments were carried out with broiler chicks from day-old to three or four weeks of age to assess the effects of nitrates and nitrites from calcium, potassium, and sodium salts in the drinking water of broilers on growth, body weights, feed utilization, blood chemistries, liver tissues, and lipid oxidation...
The objective of this study was to evaluate the influence of cow age on grazing distribution relative to mountain riparian areas. In each of two years, sixty cow-calf pairs were stratified by age into the following treatments: 1) thirty first calf heifers (442 kg, body condition score (BCS)=4.5), and 2)...
Antimicrobial coatings used to reduce the risk of infection caused by tissue-contacting medical devices must address specific biocompatibility requirements including prevention of thrombosis and rise of bacterial resistance. An antimicrobial-loaded poly(ethylene-oxide) (PEO) coating has been tentatively shown to be non-fouling with sustained antimicrobial activity. However, the presence of the antimicrobial,...
