Opportunity costs : irrigation vs. hydropower

Ross, Mark 25 May 1984 (has links)
In recent years we have seen increasing debate over the allocation of PNW water resources. In particular there are conflicts over using the river system for irrigation vs. electricity production. Denying the hydroelectric system water implies higher costs to electricity consumers as producers substitute more expensive nonhydro resources. This research looked at the impact of new irrigation on PNW electricity consumers. This was done under varying assumptions of demand response and farmer payments for pumping of irrigation water. The study also examined the difference between the current policy of allowing farmers to take all the water they need, and a policy in which withdrawals are limited in periods of low streamflow. Simulations were run to determine the amount of electricity production lost because of withdrawals. These results were then used in a series of simulations to estimate the economic impacts under the various assumptions and policies. It was found that irrigation caused losses to electricity consumers. In some cases this loss was on the order of $200/acre of irrigated land. The loss was significantly mitigated under the interruptible policy. Farmer payments for irrigation energy also reduced the loss to consumers. / Graduation date: 1985

Japan's import demand for Pacific Northwest frozen corn and potatoes

Jacobsen, Twila M. 14 July 1988 (has links)
A net shift analysis was used to analyze growth in employment and value added from 1954 to 1982 in SIC 2037, Frozen Fruits, Fruit Juices, and Vegetables. This analysis indicated that the Pacific Northwest dominated the growth experienced in this sector over this time period. Oregon's share of total U.S. employment in SIC 2037 increased from 7.3 percent in 1954 to 16.1 percent in 1982. Value added in Oregon was 16.1 percent of the U.S. total in 1982, and growth in both employment and value added was at a greater rate than the overall U.S. rate of growth in this sector. Washington's share of employment increased from 10.3 percent to 13 percent, and the share of U.S. total value added in this sector grew from 11 percent to 14.2 percent. Value added by the freezing of fruits and vegetables in Idaho increased to 10.3 percent of the U.S. total in 1982, and employment grew to a share of 10.5 percent, from 3.5 percent in 1954. An informal survey of executives in six food processing plants in Oregon suggested that expanding international export markets was essential to continued growth for this industry in the Pacific Northwest. A model of Japan's import demand of frozen vegetable products, specifically corn and potatoes, is estimated using data from 1978 through 1986 of real own price at the export site, Japanese consumer expenditures adjusted by Japan's CPI, and Japan's domestic production of frozen corn and potatoes. Commerce Department data on exports by Customs District was used to disaggregate import demand by region; namely Oregon, Washington, the two together as Pacific Northwest, and the total U.S. It was found that the demand for frozen corn imports is more responsive to changes in real own price than the import demand for frozen potatoes. Income elasticities were positive and higher for frozen potato import demand than for frozen corn demand, except for Oregon originating exports. Production in Japan of frozen corn has a higher negative impact on exports from Oregon ports than Washington based exports. Production of frozen potatoes in Japan did not have a negative impact on import demand from any of the four export sites. / Graduation date: 1989

Finding techknowledgey : students' navigations of an institution's technological landscape

Dean, Allyson S. 26 April 2012 (has links)
This study explored how students navigate the technological landscape of a public, land-grant institution. Through online surveys and semi-structured, one-on-one interviews, the study operated through an anticipatory/participatory lens to research with the intent of understanding students' experiences with technology at a research institution. Using this methodology and Triandis and Triandis' (1960) Theory of Social Distance and Sanford's (1969) Theory of Challenge and Support as theoretical support, the study identified five themes regarding students' experiences with technology: (a) differences in students' perceived levels of technological fluency (b) institutional expectations of students' technological fluency, (c) variance in institutional training on educational technologies, (d) importance of personal computer ownership and Internet access, and (e) understanding individual technological needs. Coupled with the methodology, these findings serve to proffer institutional awareness and understanding of students' experiences of an institution's technological landscape. / Graduation date: 2012

Correlation between structural heterogeneity and arthropod biodiversity : implications for management of Pacific Northwest forests

Madson, Stephanie Lee 08 December 1997 (has links)
The "old-growth controversy" in the Pacific Northwest recognized thinning as the primary silvicultural practice for land managers to produce wildlife habitat while continuing to produce timber. For the foreseeable future, forest stands will be harvested to produce forest gaps and a patchwork of trees of different ages. In order to evaluate the effect of thinning on biodiversity, nine 15-year-old harvests of this type (age=70 years) were paired with adjacent old-growth and even-aged, unthinned "pole" stands. Since soil is the crucible of terrestrial biodiversity, it is critical to contrast the effects upon the forest floor of this future practice with current management. Soil and litter fauna were monitored along 250 meter transects (pitfall and Berlese sampling at ten-meter intervals) to meet the following objectives: 1) to determine biological diversity on public lands, per federal mandate, and use diversity as a management tool; 2) compare levels of biodiversity between three management strategies; 3) determine best methods to assay arthropod diversity; and 4) identify structural and environmental determinants of arthropod diversity and abundance. The study's hypotheses were: 1) old-growth forests will have greater arthropod diversity than thinned stands; 2) thinned stands will have greater arthropod diversity than unthinned stands; and 3) species found within old-growth stands, but not within unthinned pole stands, will also be found in thinned stands. This study contrasted nine Western Hemlock/Douglas-fir sites each with contrasting old-growth, thinned and unthinned pole management stands. Sites were equally blocked in Southern Oregon, the Coast Range, and the Cascade Mountains. No segment of the arthropod fauna. (i.e., pitfall-trapped epigeic macroarthropods, Berlese-extracted litter-dwelling meso- and microarthropods, or soil-dwelling microarthropods) exhibited a management (treatment) effect throughout the entire region. When the regional blocking was removed, within-region analysis generally revealed that old-growth was most distinct. Old-growth stands had the highest abundance of individuals, but were comprised of the fewest species. Thinned stands were characterized by the highest species richness. Within-region analysis revealed an interaction of management effects and specific locale effects; locale effects dominated for soil microarthropods and epigeic macroarthropods, while management options dominated for litter arthropods. Within the Southern Oregon region, I attempted to correlate arthropod community structure (canonical correspondence analysis (CCA) of within-stand samples) with a suite of soil chemical and microbiological descriptors. Full analysis of twelve variables within one exemplary stand revealed several potential trends (negative: dissolved organic carbon, soil moisture, distance from the beginning of the transect; positive: total CO��� field respiration, mineralizable nitrogen, water-induced respiration, substrate-induced respiration). Relatively shallow slopes and very low r-value coefficients of correlation characterized all statistical tests. Few of the trends apparent at one site were paralleled at more than one other site; at all sites potential correlates had very low r-values. No community revealed separate clouds in CCA analysis, indicating distinct "micro-communities" of arthropods inhabiting distinct micro-habitats. Lack of distinctive species assemblages and lack of correlation with microhabitat variables indicated that arthropods respond on different temporal and/or spatial scales then the microbial-oriented variables, and that each taxon is responding in an individual manner. / Graduation date: 1998

Ties undone : a gendered and racial analysis of the impact of the 1885 Northwest Rebellion in the Saskatchewan district

Millions, Jodi Erin 03 December 2007
The Northwest Rebellion, in comparison to other North American civil wars, was short-lived and geographically contained, but for the people who lived through it, the residents of the Saskatchewan district, 1885 was a real and a frightening ordeal. By exploring micro-relations at the individual, family and community levels, and focusing on the connections between residents and ways that they related to each other, a portrait of the region emerges that reveals that Euro-Canadians and Aboriginals were linked to each other in many, and often subtle ways before the uprising. Drawing on personal papers, government and Hudson's Bay Company records, and oral histories, this study shows that race and gender were determining factors in how white, First Nations, Metis and mixed-blood men and women experienced both the conflict itself and its aftennath. Furthermore, its impact on residents' lives and society in the Saskatchewan territory was considerable and the effects long-lasting. Barriers, both physical and social, were created and solidified, and, although groups were still linked by the same family ties that bound them before the spring of 1885, the ways that they viewed each other changed after the rebellion. Mistrust and hostility that had not existed before, or that had been repressed, broke the bonds that connected racial groups, and sometimes families. The new order in Saskatchewan was one in which Euro-Canadians held power, and Aboriginals were second-class citizens barred from mainstream society. The rebellion accelerated white domination of the region, and acted as a catalyst for the racial divisions evident in Saskatchewan in the twentieth century.

Mycorrhizal and other root endophytic fungi of lupines in the Pacific Northwest

O'Dell, Thomas E. 12 May 1992 (has links)
We investigated the root endophytic fungi of lupine using four approaches: (1) occurrence of fungal colonization in field-collected roots; (2) growth response of L. latifolius to inoculation with two types of fungi; (3) structure of root colonizations of Pinus and Lupinus by Phialocephala fortinii, a septate endophytic fungus of lupine; and (4) comparison root morphology, mycorrhizal colonization and natural ¹⁵5N-abundance N₂ fixation of three legumes. In part 1, three species of Lupinus were never observed to have fungal colonization; nine species were colonized by VA mycorrhizal fungi; seven species were colonized by fungi with septate hyphae which often formed intracellular scierotia, here called septate endophytes. In part 2, shoot weight of 16 week old L. latifolius seedlings in the greenhouse was significantly reduced by Glomus spp. in one experiment; p. fortinii significantly increased nodule weight in one experiment and reduced it in the other. In part 3, P. fortinii colonized root epidermal and cortical cells in the root hair zone on ultimate lateral pine roots, as well as cortical and epidermal cells of primary roots of Pinus and Lupinus. Fungal colonization was inter- and intracellular with scierotia forming in cells of both hosts. Labyrinthine tissue, a type of fungal differentiation which occurs in the Hartig net of ectomycorrhizae, formed sporadically on pine roots. In part four, Roots of Lupinus albicaulis cv. hederma had a significantly larger proportion of coarse roots (> 1 mm diameter) and significantly less mycorrhizal colonization than two other legumes, Medicago lupinula and Trifolium hybridum. Estimated aboveground N derived from fixation ranged from 6.1 to 39.9 kg per hectare (average = 22.0 kg/ha) and did not vary significantly among species. / Graduation date: 1992

Independent Filmmaking in the Pacific Northwest: A Critical Analysis of the Regional Film Landscape / Critical Analysis of the Regional Film Landscape

Erickson, Mary P. A., 1977- 06 1900 (has links)
xvii, 397 p. : ill., maps. / Thousands of films are produced every year in the United States, and only a fraction of these is made by mainstream Hollywood film studios. Independent filmmakers working in regional locations produce the majority of these films, retaining financial, creative and distribution control and working with locally-based cast and crew members. This film activity must be acknowledged in order to fully understand the American film industry. This study examines regional independent filmmaking through case studies of two film communities: Portland, Oregon and Seattle, Washington. Using political economy of communication as the primary theoretical foundation, this study focuses on the infrastructure (systems, policies, resources and practices) that supports and/or limits the production and distribution of independent films. The research utilizes extensive document analysis of historical materials and contemporary documents produced by organizations and individuals, as well as a survey of 60 film professionals and interviews with over 40 film professionals. A central challenge to independent filmmaking is the term "independent," which has been contested by film professionals and scholars; therefore, this study analyzes and offers a new definition of "independent filmmaking." The history of filmmaking activity in Portland and Seattle is presented, as well as an extensive discussion of the contemporary landscape of regional independent filmmaking in these two communities. The study finds that there are a multitude of contradictions pertaining to financing, distribution, labor and myths of independent filmmaking. These contradictions present a range of opportunities and challenges that often simultaneously conflict with each other. The filmmaking communities in Portland and Seattle have notable networks of support, including professional and educational organizations, film festivals, government initiatives and a few locally-operated distributors. However, filmmakers in both cities also share challenges in financing, distribution and labor. The study argues that regional independent filmmaking has made a dynamic and influential contribution to the American film industry and cultural production but has been under-explored in academic scholarship. The research also points to the need to examine and understand the contradictions of independent filmmaking to improve the circumstances and infrastructure that support regional independent filmmaking. / Committee in charge: Dr. Janet Wasko, Chairperson; Dr. Gabriela Martinez, Member; Dr. H.
