  • On the evolution of correlated color traits in garter snakes

    Creator:
    Westphal, Michael F.
    Abstract:
    How complex traits evolve continues to be a major focus of evolutionary investigation. A current topic of debate is the hypothesis that the phenotypic integration of complex traits gives rise to evolutionary constraints. I studied two color traits in the common garter snake, Thamnophis sirtalis, that show a high level...

  • An investigation into the genetic basis of migration timing in Chinook salmon (Oncorhynchus tshawytscha)

    Creator:
    O'Malley, Kathleen G.
    Abstract:
    The genetic basis of adaptation is complex as many fitness-related traits are quantitative and likely influenced by multiple genes with variable effects across different selective environments. One important adaptation for anadromous Chinook salmon (Oncorhynchus tshawytscha) is the time at which individuals return to natal breeding sites within a reproductive season....

  • Social justice counseling : A study of social justice counselor training in CACREP-accredited counselor preparation programs

    Creator:
    Ratts, Manivong J.
    Abstract:
    There is a growing movement within the counseling profession calling on counselors to integrate a social justice perspective into counseling theories, paradigms, and practices. However, there are no empirical studies illustrating how counselor preparation programs accredited by the Council for Accreditation of Counseling and Related Educational Programs (CACREP) are preparing...

  • Spatial and temporal scales of genetic change in two overfished rockfishes

    Creator:
    Gomez-Uchida, Daniel
    Abstract:
    Pacific rockfishes (genus Sebastes) have attracted wide scientific and public interest from an evolutionary, fishery and conservation standpoints. This dissertation addresses several hypotheses involving spatial and temporal scales of genetic change in two overfished rockfishes, darkblotched (S. crameri) and canary rockfish (S. pinniger), using statistical analyses of genetic variation within...

  • Neural gene expression profiling in chinook salmon (Oncorhynchus tshawytscha) of alternate run times

    Creator:
    Bernier, Jeremiah C.
    Abstract:
    Chinook salmon (Oncorhynchus tshawytscha) display the greatest variability of return times to freshwater of all Pacific salmon. Differential return times to freshwater have segregated populations of Chinook into two broad types or runs, fall and spring, named for the time of year in which they migrate to freshwater. Migration time...

  • A GIS Evaluation of Land Use Zones and Water Quality for Marine Conservation Site Selection in Lincoln County, Oregon

    Creator:
    Henderson, Ann Miller
    Abstract:
    The leasing of submerged and submersible lands is emerging as a new marine conservation method. Using a geographic information system, this study: (1) examines the suitability of estuary tideland sites for conservation leasing in Lincoln County, Oregon, and (2) explores the relationship between adjacent terrestrial land use zones and the...

  • 3-D finite element modeling in OpenSees for bridge live-load girder distribution factors

    Creator:
    Scoggins, Luke A.
    Abstract:
    A generalized, three-dimensional, finite element bridge model was created in order to efficiently and accurately assess live-load girder distribution factors for a variety of bridge types. This model shortens the time required by bridge analysts to develop individual finite element models for bridges of varying geometries. The creation of the...

  • Preventing falls from unpredictable balance disturbances

    Creator:
    Welsh, Lisa R.
    Abstract:
    Falls, particularly those due to slips, constitute a major health risk for older adults. Past research has found that individuals can learn not to fall through repeated exposure to a slipping perturbation. Slips can be unpredictable, however. The goal of this study was to determine whether similar adaptations would occur...

  • Dynamics of organic matter production and degradation during coastal diatom blooms

    Creator:
    Wetz, Michael S.
    Abstract:
    Experiments were designed to answer key questions about diatom-derived organic matter cycling (i.e., production and degradation) in coastal systems. Dissolved organic matter (DOM) production was examined in axenic batch cultures of five diatom species. Dissolved organic carbon (DOC) release rates varied between species, but were significantly higher for all species...

  • Language Differences between Women and Men and the Attribution of Leadership

    Creator:
    Dunsworth, Sabrina J.
    Abstract:
    This research addresses the perception of leadership attributes in light of evaluator and target gender. It specifically investigates whether there is a difference in language usage when the evaluator is female versus when the evaluator is male. Two studies were conducted. A pre-test used instrumental development drawing from studies conducted...
