The present study employs a normalized restricted quadratic profit function approach to estimate lumber and plywood supply and Marshallian factor demand elasticities for four region-product combinations in Oregon for the period 1970-2010. The four log demand functions will be employed as the "demand side" of the log market model of...
Declines in glacier area and volume are widespread. These changes will have important hydrologic consequences since glaciers store tremendous amounts of fresh water and buffer seasonally low flows in many densely populated regions. In this thesis I focus on a region that is hydrologically vulnerable to glacier change, namely the...
Hardrock mining is associated with severe environmental and economic costs. Of particular concern is acid mine drainage which has contaminated several thousand kilometers of streams across the United States representing a formidable danger to watershed health. Given the high risks of this activity, ensuring high regulatory standards may be an...
In 2011, a study by Freeman and Wornell uncovered that social service providers in Klamath County believed Native American children experiencing maltreatment might be slipping through the cracks. In an effort to find out how to better serve these children and their families, the current study involved interviews with 11...
American Indians presently face health risks posed by exposure to environmental pollutants through different exposure routes including: inhalation (e.g., air particles), ingestion (e.g., fish, water), and dermal contact (e.g., contact with water, soil). Geographic Information Systems (GIS) are increasingly being used in the Environmental Health arena as a tool for...
The Long Tom Watershed Council (LTWC) is a non-profit organization in Eugene, Oregon that serves to protect and enhance watershed health in the Long Tom River Basin. The Amazon Creek Initiative was launched by the LTWC in 2011 as Oregon’s newest Pesticide Stewardship Partner. Goals of the initiative are to...
Data can be represented in multiple views. Traditional multi-view learning methods (i.e., co-training, multi-task learning) focus on improving learning performance using information from the auxiliary view, although information from the target view is sufficient for learning task. However, this work addresses a semi-supervised case of multi-view learning, the surrogate supervision...
Woody biomass transportation costs and market values/costs are strongly correlated with the woody biomass moisture content. Properly managing moisture content can potentially lead to economic and environmental advantages in biomass energy markets. Good management requires accurate moisture content measurements. Therefore, availability of accurate, precise, reliable, and efficient tools to assess...
Parks help to build social cohesion within a community. Urban open spaces offer
a sense of place, act as the focal points for public gatherings, and provide an
opportunity for social networking (Francis, 2003; Hayward, 1989). While offering so
much they are also known to be places of disgust and...
The objective of this study was to evaluate the effect of commodity promotion activities on the United States' hazelnut farmer's economic welfare. Commodity promotion activities, such as generic advertising and research, are the responsibilities of government mandated commodity commissions, such as the Hazelnut Marketing Board (HMB). The HMB is a...
