  • Thresholds of uncertainty : radiation and responsibility in the fallout controversy

    Creator:
    Jolly, J. Christopher
    Abstract:
    The public controversy over possible health hazards from radioactive fallout from atomic bomb testing began in 1954, shortly after a thermonuclear test by the United States spread fallout world wide. In the dissertation, I address two of the fundamental questions of the fallout controversy: Was there a threshold of radiation...

  • The effects of multiple pathogens on amphibians in the Pacific Northwest

    Creator:
    Romansic, John M.
    Abstract:
    The earth is undergoing a “biodiversity crisis” characterized by loss of populations, species, genetic diversity, and ecosystem services. Part of this crisis consists of population declines, extinctions, and increased incidence of deformities in amphibians. It is unknown whether deformities contribute to these declines. Many cases of population declines in amphibians...

  • Student, teaching assistant, and faculty learning during innovation in an introductory biology course

    Creator:
    Blair, Lesley
    Abstract:
    This study examined the dynamics of student, teaching assistant (TA), and faculty learning in relationship to implementation of a genetic technologies project in a university introductory biology course. Research focused on the types of learning that occurred and the various factors impacting that learning. Study participants included 25 undergraduate non-science...

  • Husbandry stress of Zebrafish, Danio rerio

    Creator:
    Ramsay, Jennifer Mara
    Abstract:
    Zebrafish, Danio rerio, are widely used as vertebrate research organisms yet little is know about their responses to husbandry stressors. This dissertation examined the whole-body cortisol responses of zebrafish to husbandry stress. Additionally, the effects of stress on the susceptibility to mycobacteriosis and microsporidiosis (Pseudoloma neurophilia) were determined including effects...

  • The effect of teacher training on movement implementation in elementary classrooms

    Creator:
    Abramovitz, Jan Samuel
    Abstract:
    The purpose of this dissertation was to explore the effect of teacher training on the nature and context of movement instruction in Oregon elementary schools. While there are numerous instructional guides and many anecdotal descriptions of classroom movement highlighting the work of movement arts specialists, to the best of our...

    Creator:
    Longo, Bernadette Mae
    Abstract:
    After 22 years of eruption at Kilauea Volcano, Hawai'i, an environmental, epidemiological, and ethnographic study was conducted to assess for adverse health effects from chronic exposure to volcanogernc air pollution. Environmental data from 2003 indicated that Kau District, from 37 to 74 km downwind from the eruption, was being exposed...

  • Survival and persistence of Bacteroidales human and ruminant specific fecal markers and occurrence with fecal pathogens

    Creator:
    Walters, Sarah P.
    Abstract:
    Aquatic fecal contamination from non-point sources impairs environmental health and serves as a vehicle for transmission of waterborne disease, resulting in economic losses worldwide. Accurate methods of diagnosing fecal pollution and its source are needed to prevent human exposure, remediate pollution, and reduce economic impacts. In order to obtain this...

  • Predicting the stability, equilibrium response, and nonequilibrium dynamics of ecological systems

    Creator:
    Hosack, Geoffrey R.
    Abstract:
    In this dissertation, new theory and its applications are developed to predict three properties of complex ecological communities: stability, equilibrium response, and non-equilibrium dynamics. First, a graph-theoretic analysis identifies the interconnections in a complex ecosystem that promote or diminish stability (Chapter 2). The hierarchy of interactions that influences stability and...

  • Translation of dengue virus RNA : influence of the untranslated regions on 5´-cap dependent translation and ribosome scanning

    Creator:
    Chiu, Wei-Wei
    Abstract:
    In this thesis, I studied the translation of dengue virus RNA using a luciferase reporter gene system in Vero cells. The dengue reporter mRNA construct, which harbors 5´-terminal viral nts and 3´-terminal nts, could be translated efficiently compared to an alpha globin reporter construct. The 5´-cap structure and 3´-untranslated region...
