  • Breaking silos : interdisciplinary research in kinesiology

    Creator:
    Schary, David P.
    Abstract:
    With the growing popularity of kinesiology at the undergraduate level, one would expect the field to be influential. Kinesiology, however, appears to be in a paradox. The undergraduate popularity is not reflected in the rest of academia, or even the general public, many of whom feel kinesiology is not a...

  • Science and technology in cutting-edge agricultural biotechnology research

    Creator:
    Xia, Yin
    Abstract:
    The genetic engineering made possible by the discovery of recombinant DNA has played an increasingly important role in agricultural research. The present study employs a knowledge production model to assess the efficacy of, and relationship between, basic and applied research in agricultural biotechnology, allowing for both complementarity and substitutability between...

  • Nitrogen release from granules of sulfur-coated urea

    Creator:
    Jarrell, Wesley M.
    Abstract:
    Sulfur-coated urea (SCU) is a slow release nitrogen fertilizer manufactured by the Tennessee Valley Authority. Urea granules are sprayed with molten sulfur, then holes in the sulfur coating are sealed with a layer of wax sealant. The sulfur coatings are mixtures of amorphous and crystalline allotropes of sulfur. Coating thickness...

  • Communicating the wildland fire message : an investigation of agency outreach strategies

    Creator:
    Toman, Eric Lee
    Abstract:
    Wildfire impacts have increased in recent years. The management response outlined by recent policy initiatives (e.g., the National Fire Plan, Healthy Forests Restoration Act) emphasizes the use of prescribed fire and mechanized thinning to reduce the risk of future fire events. These policies also call for an unprecedented level of...

  • Stability of reporter gene expression and RNAi in transgenic poplars over multiple years in the field under vegetative propagation

    Creator:
    Li, Jingyi
    Abstract:
    Stable expression of transgenes is required for commercial uses of genetically engineered trees. To better understand the stability of transgene expression under field conditions, we studied transgene expression and RNA interference (RNAi)-induced transgene suppression in 2,480 transgenic poplars (460 transgene insertion events) over three years. Stability of expression was assessed...

  • The ecological legacy of Indian burning practices in southwestern Oregon

    Creator:
    Carloni, Kenneth R.
    Abstract:
    Two research questions are posed: (1) How have ecosystem conditions changed through time in southwestern Oregon? (2) How have culture-driven and climate-driven processes contributed to ecosystem change in southwestern Oregon? A brief introduction to the Little River study area is followed by a cultural and ecological history of the watershed....

  • Gas injection consolidation of miniature natural fiber beams

    Creator:
    Kim, Jae-Woo
    Abstract:
    The internal structure of natural fiber composites can be manipulated by controlling the spatial distribution of fiber orientation and internal chemical and thermodynamic conditions during their consolidation. Objects highly tailored to specific service demands may thereby be produced. Techniques to form miniature structural beams from oriented hemp and random wood...

  • Sea urchin-kelp forest communities in marine reserves and areas of exploitation : community interactions, populations, and metapopulation analyses

    Creator:
    Moctezuma, Gabriela Montaño
    Abstract:
    Marine ecosystems can be exposed to natural and anthropogenic disturbances that can lead to ecological failures. Marine reserves have been lately suggested to protect marine populations and communities that have been affected by habitat destruction and harvest. This research evaluates the potential role of two marine reserves established in Oregon...

  • Hydrology and geomorphic evolution of basaltic landscapes, High Cascades, Oregon

    Creator:
    Jefferson, Anne (Anne Jarvis)
    Abstract:
    The basaltic landscapes of the Oregon High Cascades form a natural laboratory for examining how geologic setting and history influence groundwater flowpaths, streamflow sensitivity to climate, and landscape evolution. In the High Cascades, highly permeable young basaltic lavas form extensive aquifers. These aquifers are the dominant sources of summer streamflow...

  • How does a collaborative community affect diverse students' engagement with an open source software project : a pedagogical paradigm

    Creator:
    Morgan, Becka S.
    Abstract:
    Open Source Software (OSS) communities are homogenous and their lack of diversity is of concern to many within this field. This problem is becoming more pronounced as it is the practice of many technology companies to use OSS participation as a factor in the hiring process, disadvantaging those who are...
