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...

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...

The extent and implications of specified resource site protection in Oregon

Creator:: Giampaoli, Peter Paul
Abstract:: The protection of sensitive resources is an integral part of forest practices regulations in many states, affecting non-industrial private forest (NIPF) landowners. In Oregon, forest operations on private lands which will conflict with sensitive areas designated "specified resource sites" must meet spatial and temporal requirements to protect those sites. These...

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...

Factors Influencing Streamflow Generation Processes in Rain-dominated, Coastal Watersheds in Oregon

Creator:: Pazdral, Rosemary
Abstract:: Relative to other systems in the PNW, the rain-dominated, coastal watersheds of western Oregon have shallow aquifers. Given the seasonality of streamflow and storage limitations in coastal, rain-dominated watersheds, changes in the temporal patterns of precipitation have the potential to magnify the risk of extreme streamflow conditions during both high-...

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?...

Stream Chemistry in the Oregon Coast Range: Spatial and Temporal Variation

Creator:: Carini, Lya
Abstract:: Hydrological and biogeochemical processes occurring throughout a watershed are typically reflected in stream water chemistry, including in coastal watersheds. While Oregon Coast Range streams have been studied in the past, there is a dearth of knowledge in terms of seasonal temporal trends and spatial variability that this study seeks to...

The relationship between income and food insecurity : the role of social support in rural and urban Oregonians

Creator:: De Marco, Molly M.
Abstract:: Millions of U.S. households experienced hunger in 2005 and millions more experienced food insecurity. Previous research indicates that low-wage work and little social support contribute to food insecurity. Research also suggests that individuals cope by finding alternate food sources and drawing on social support. Further, researchers have found that rural...
