Severe infection by the endemic myxozoan parasite, Ceratonova (synonym, Ceratomyxa) shasta, has been associated with declines in and impaired recovery efforts of populations of fall-run Chinook Salmon Oncorhynchus tshawytscha in the Klamath River, California. The parasite has a complex life cycle involving a polychaete worm host as well as a...
Since 1935, France has introduced a set of strict national wine rules and regulations, the Appellation d’Origine Contrôlée (AOC). The AOC limits fraud and oversees quality control by basing the rules on terroir. High quality from terroir comes has both physical and cultural factors. Before 1935, France produced a variety...
Organically certified Northern Highbush Blueberry (NHB; Vaccinium corymbosum L.) production in the Columbia Basin region of Oregon and Washington is expanding. Soils in the region are typically calcareous and highly alkaline, often requiring pH adjustment to an ideal range of 4.5–5.5 to support the establishment of the acid-loving, ericaceous crop....
My dissertation title is, “Applied economic strategies to evaluate policies and environmental outcomes: case studies from immigration and ecosystem services.” The first two chapters of this dissertation concern the relationship between local immigration policies and societal welfare. The third chapter examines the impact of human activity on the environment and...
Recent studies have shown that novel continuous dropout methods can be viewed as a Bayesian interpretation of model parameters, though most such studies have shown results using normal distributions. As the posterior distributions over neural network nodes and parameters are intractable, given that they are a result of artificial construction...
The growing need for accurate forest biomass and carbon estimates has sparked a recent re-examination of direct volume estimation and taper modeling techniques. Additionally, the need for increased precision of biomass and carbon estimates drives a need to improve the techniques used to evaluate these models. Taper equations have an...
The aerodynamic performance of an oscillating pitching and plunging foil operating in the energy harvesting mode is investigated. Experiments are conducted in a closed-loop recirculating wind tunnel at Reynolds numbers of 24,000 to 48,000, and reduced frequencies (k = fc/u) of 0.042 to 0.083. Foil kinematics are varied through the...
In order to assist WAC/WID practitioners and science writing faculty in incorporating translingual perspectives in disciplinary writing instruction, this study extends translingualism to language practice in the sciences by conducting a corpus study of Al-Awamia, a Moroccan agronomic journal. Mapping rhetorically significant changes across abstracts authored in English, French, and...
Many economically important Pacific salmon fisheries along the west coast of North America are mixed-stock, recreational systems, in which managers strive to account for interactions between fish, anglers, and management policy while balancing fishery access against conservation of vulnerable stocks. Specific challenges facing fisheries managers include limited control over angling...
There is currently a revolution in archaeological morphometric research. As advances in technology are making more in-depth analyses both time and cost efficient. In this work, a collection of artifacts from the Pilcher Creek site (35UN147) in eastern Oregon was digitized using high resolution three-dimensional scanning. These scans were then...
