Radically reframing environmental problems : The Salmon 2100 case study

Creator:: Lane, David Earl
Abstract:: There are typically two responses to the complex environmental problems of our time: 1) doom and gloom and 2) optimism. There is a lot of doom and gloom in the environmental literature. This literature warns that the future portends danger for humans and their life support systems. But when one...

Exploring Student Reflections Towards an Agricultural Internship

Creator:: Henderson, Thomas M.
Abstract:: The agricultural industry across the United States is experiencing a shortage of qualified and interested young professionals who aspire to enter the agricultural sector. Internships have largely been used as an effective hands-on learning tool, exposing college students to an array of occupational skills and expectations in hopes of creating...

The migratory pattern of audlt sockeye salmon (Oncorhynchus nerka) in Bristol Bay as related to the distribution of their home-river waters

Creator:: Straty, Richard R.
Abstract:: The individual stocks of sockeye salmon that make up the annual spawning migration to the Bristol Bay region of Western Alaska are produced in the lakes and streams of ten major river systems, which discharge into the bay over a shoreline distance of 120 miles. The hypothesis adopted in this...

From running birds to walking robots : optimization as a unifying framework for dynamic bipedal locomotion

Creator:: Hubicki, Christian M.
Abstract:: Bipedal locomotion is a complex phenomenon to understand and control, making it difficult for legged robots to achieve the speed, agility, efficiency, and robustness of their animal counterparts. This thesis argues for the use of numerical optimization to investigate and implement bipedal control as it applies to biology, dynamical models,...

Politicized Collective Illness Identity and Boundary-Spanning in Western Montanan Community Health Workers: An Ethnographic Study

Creator:: McQuillan, Kindra
Abstract:: Background: Against global health disparities and a shortfall of medical personnel, community health workers (CHWs) promise a solution based in lived experience and connection to the health system. To address global and upstream health determinants, CHW programs engage the perspectives of both the workers they employ and the communities they...

Designing and understanding information retrieval systems using collaborative filtering in an academic library environment

Creator:: Jung, Seikyung
Abstract:: Accessing information on the Web has become ingrained into our daily lives, and we seek information from many different sources, including conference and journal publications, personal web pages, and others. Increasingly, web-based information retrieval systems such as web-based search engines, library on-line catalog systems, and subscription-based federated search systems are...

Dynamics and control for spring-mass legged robots

Creator:: Vejdani Noghreiyan, Hamid Reza
Abstract:: The objective of this study is to propose control strategies for legged robots to walk and run naturally like humans and animals. To achieve this goal, we use the spring-mass model for the legged robots to be able to create the same dynamics in the leg as humans and animals....

Dynamics of the Columbia River tidal plume

Creator:: Kilcher, Levi F.
Abstract:: This dissertation investigates the dynamics of the tidally modulated outflow from the Columbia River mouth using high resolution measurements of velocity, density and turbulent microstructure. At high tide, flow through the river mouth reverses from flood (onshore) to ebb (offshore). During ebb, buoyant fluid issues from the river mouth and...

Patterns of crown damage within a large wildfire in the Klamath-Siskiyou bioregion

Creator:: Thompson, Jonathan R.
Abstract:: The 2002 Biscuit Fire burned through more than 200,000 ha of mixed conifer/ evergreen hardwood forests in southwestern Oregon and northwestern California. The remarkable size of the fire and the diversity of conditions through which it burned provided an opportunity to analyze the correlates of burn severity across vegetation types...

Monitoring potato leafroll virus movement in differentially aged potato (Solanum tubersom L.) plants with an immunosorbent direct tissue blotting assay

Creator:: Whitworth, Jonathan L.
Abstract:: Potato leafroll virus (PLRV) causes yield and quality losses in potato. PLRV is identified by plant symptoms and serological tests such as an enzyme-linked immunosorbent assay (ELISA). A similar serological test, direct tissue blotting assay (DTBA), was used to detect and monitor PLRV movement in field-inoculated Russet Burbank plants and...
