  • Evaluating the public health risks of methylmercury exposure and benefits from omega-3 fatty acids and selenium from fish consumption

    Creator:
    Cusack, Leanne K.
    Abstract:
    Although fish are a nutritious food source, they also are the main source of methylmercury exposure in U.S. populations. This research examined the risks from methylmercury and benefits from omega-3 fatty acids and selenium from fish consumption. The first study provided the first region-specific quantitative risk/benefit analysis for nine commonly...

  • Social Vulnerability Index for the state of Oregon (2020 ACS data)

    Creator:
    Reilley, Caitlyn and Crandall, Mindy
    Abstract:
    Senate Bill 762, Oregon’s 2021 omnibus wildfire bill, directed Oregon State University to conduct a wildfire risk assessment including mapping socially vulnerable communities to help inform decisions and allocate resources related to state wildfire prevention, response, and recovery. This dataset was curated to identify socially vulnerable communities and largely follows...

  • Fire regime parameters and their relationships with topography in the east side of the Southern Oregon Cascade Range

    Creator:
    Foster, John S.
    Abstract:
    The fire regimes of a 9,000 hectare study area on the east side of the Southern Oregon Cascades are described. Fire regime parameters included are frequency, extent, and predictability of fire return interval. Severity of two fires is mapped by type of evidence. Changes in fire regime due to fire...

  • A Holistic Model: A risk assessment model for internal conflict and case study of the Democratic Republic of Congo

    Creator:
    Gharib, Camron I.
    Abstract:
    Internal conflicts are detrimental to a country’s development for a number of reasons. Therefore, it is beneficial to identify the factors that lead to internal conflict. The three perspectives used to understand why internal conflicts occur are the systemic lens, the individualist perspective, and an interpretation that emphasizes the role...

  • Autonomous Decision Making Facing Uncertainty, Risk, and Complexity

    Creator:
    Short, Ada-Rhodes
    Abstract:
    The creation of autonomous decision makers to handle potentially hazardous or logistically complicated tasks is desirable for the purpose of reducing human labor and exposure to risk, and for increasing the general performance of autonomous systems in a wide variety of environments. However, traditional autonomous decision makers perform poorly when...

  • Probabilistic Multi-hazard Earthquake-Tsunami Structural Risk Assessment Framework

    Creator:
    Alam, Mohammad Shafiqual
    Abstract:
    Catastrophic earthquake and tsunami events that resulted in significant loss of life and property over the past two decades have raised the global awareness regarding the need to understand the response of communities and their built environment to multi-hazard extreme events. In recognition to this impending threat to the coastal...

  • Improving ecological risk assessment of pesticides for nontarget terrestrial vertebrates

    Creator:
    Wang, Guiming
    Abstract:
    The Quotient Method (QM) is used by the United States Environmental Protection Agency (USEPA) in ecological risk assessments of pesticides for nontarget organisms. The QM requires several assumptions regarding exposure and hazards of pesticides to wildlife; several of these assumptions have not been tested. During 1997-99, I conducted three experiments...

  • Integrative risk analysis of vector-borne disease

    Creator:
    Orme Zavaleta, Jennifer
    Abstract:
    In this dissertation I explore the application of two novel modeling techniques for improving risk analysis of vector-borne disease and discuss their potential use in integrating environmental risk assessment that guides environmental and public health decisions. Techniques for analyzing risk have been considered inadequate due to a lack of understanding...

  • Organizational factors in the reliability assessment of offshore systems

    Creator:
    Biondi, Esteban L.
    Abstract:
    The reliability of ocean systems is dependent on organizational factors. It has been shown that low probability / high consequence system failures are overwhelmingly induced by organizational factors. However, no methodology is yet widely accepted for the evaluation of this phenomenon or its accurate quantification. A qualitative complementary approach is...

  • Risk-based design for multidisciplinary complex systems

    Creator:
    Farhangmehr, Farzaneh
    Abstract:
    The ultimate goal of large-scale design organizations are mainly to reduce costs and improve reliability and performance of systems while assessing how much risk (cost, schedule, scope) they can take and still remain competitive. To achieve this goal they need to develop tools to reach the most preferred design product...
