Predicting channel stability in Colorado mountain streams using hydrobiogeomorphic and land use data : a cost-sensitive machine learning approach to modeling rapid assessment protocols

Creator:: Morét, Stephanie L.
Abstract:: Natural resource data are typically non-linear and complex, yet modeling methods often utilize statistical analysis techniques, such as regression, that are insufficient for use on such data. This research proposes an innovative modeling method based on pattern recognition techniques borrowed from the field of machine learning. These techniques make no...

Estimation and Sparse Selection of Conditional Probability Models for Vector Time Series

Creator:: Ruiz, Trevor D.
Abstract:: Diverse scientific fields collect multiple time series data to investigate the dynamical behavior of complex systems: atmospheric and climate science, geophysics, neuroscience, epidemiology, ecology, and environmental science. Identifying patterns of mutual dependence among such data generates valuable knowledge that can be applied either for inferential or forecasting purposes. Vector autoregressive...

Sources and perceptions of controversy in establishing a protected area for biodiversity : a case study in the New River Area of Oregon

Creator:: Erickson, Dana C.
Abstract:: The process of land acquisition for the conservation of plants or wildlife habitat can raise controversial issues, issues often perceived differently by the individuals and groups involved. After the land acquisition process is completed, there is rarely an opportunity to analyze the differing perceptions of the issues and their relative...

Utilizing cooperative fisheries research to monitor and understand harmful algal blooms along the Oregon coast

Creator:: Gilliland, Raquel C.
Abstract:: Harmful algal blooms (HABs) are a problem for coastal communities, the fishing industry, and coastal organisms. Pseudo-nitzschia spp. is a regularly occurring diatom in Oregon’s coastal waters. At times, Pseudo-nitzschia spp. can facultatively produce domoic acid, a neurotoxin that can bioaccumulate in the food chain. While regular shore-based sampling provides...

Assessing Contention: Understanding Nuclear Waste Storage Opposition in the U.S. and Canada

Creator:: Rubenstrunk, Rebecca
Abstract:: Attempts to site nuclear waste storage facilities are highly contentious. Given that nuclear related facilities are the most commonly opposed types of proposed land uses, one might expect to observe strong contentious interactions between proponents and immediate community members. In some cases, what is expected is not necessarily observed; why?...

Voluntary environmental programs at an alpine ski area: influence of recreationists' knowledge, motivations, attachment, value orientations, and specialization

Creator:: Little, Christopher M.
Abstract:: Voluntary environmental programs (VEPs) have been created to encourage companies to engage in behaviors that mitigate environmental impacts (e.g., recycling, emissions reduction). Many ski areas participate in the Sustainable Slopes Program, an initiative that promotes VEPs in the ski area industry. Past research has addressed the performance of VEPs in...

Plant selection, irrigation requirements and stormwater management of Pacific Northwest extensive green roofs

Creator:: Shroll, Erin
Abstract:: An alternative to traditional roofing, extensive green roofs are contained ecosystems consisting of a drainage layer, a thin media profile which is planted with hardy plant species. Extensive green roof plants must maintain multiple functions while growing in a highly aggregate media at a depth of equal to or less...

Emerging Impacts Resulting from the Implementation of the United States Pacific Coast Groundfish Trawl Rationalization Program

Creator:: Thompson, Jenny
Abstract:: On January 11, 2011, the Pacific Fishery Management Council (PFMC) instituted a catch share program for the West Coast groundfish trawl fishery. The program was intended to create a more sustainable fishery and increase economic efficiency through the use of individual fishing quotas and fishing cooperatives. While there are extensive...

Decanting values of the environment: A comparative case study in the Willamette Valley’s wine industry

Creator:: Cogle, James M.
Abstract:: The Oregon wine industry is growing and becoming increasingly valuable to the regional economy. As with many production industries, the wine industry has faced concerns around its environmental practices and community impact. The use of synthetic pesticides, herbicides, fertilizers, and associated wastewater run-off are a few issues vineyard managers experience....

Beliefs and attitudes influence willingness to pay recreation fees at an urban forest : incorporating attitudes in contingent valuation methods

Creator:: Moehrke, Caitlin
Abstract:: The current thesis presents contingent valuation research incorporating social psychological measures that investigates recreationists' willingness to pay recreation access fees at McDonald-Dunn Forest, Oregon. Context is provided through an extensive literature review of recreation fee management, issues and concerns related to recreation fees, recreationists' attitudes toward fees, relevant social psychological...
