  • The economics of a research program : knowledge production, cost, and technical efficiency

    Creator:
    Qin, Lin
    Abstract:
    Calls continually are made to provide economic assessments of research program achievements and efficiency. Yet little effort has been given to develop an assessment framework that would focus on the research discovery itself, treating the research manager as a producer and the research technology as a knowledge production function. The...

  • White-breasted nuthatch density and nesting ecology in oak woodlands of the Willamette Valley, Oregon

    Creator:
    Viste-Sparkman, Karen
    Abstract:
    Habitat loss causes a reduction in available resources for wildlife, alters the configuration of remaining habitat, and may isolate wildlife populations. White-breasted nuthatches (Sitta carolinensis) are experiencing long-term population declines in the Willamette Valley of Oregon, where they are historically associated with oak woodlands. As secondary cavity-nesters, white-breasted nuthatches may...

  • Extreme value index estimation with applications to modeling extreme insurance losses and sea surface temperatures

    Creator:
    Henry, John B.
    Abstract:
    The extreme value index (EVI) links the generalized extreme value (GEV) distribution and the generalized Pareto (GP) distribution. These two distributions are fundamental in extreme value theory (EVT), with the GEV distribution being the only possible non-degenerate limiting distribution of properly normalized maxima of iid random variables, and the GP...

  • The evolutionary stability of partial migration

    Creator:
    Ohms, Haley A.
    Abstract:
    Natural selection, in its most basic form, is described as a process in which traitsincrease or decrease in frequency depending on their fitness, and only the trait withthe highest fitness will remain in the population. Yet, populations rarely have asingle `optimal' trait. The way natural selection maintains this observed variationwithin...

  • Candidate Causes, Consequences, and Estimation of Individual Diet Specialization

    Creator:
    Coblentz, Kyle E.
    Abstract:
    Diet variation among individuals within populations is widespread. Often diet differences among individuals are attributable to obvious differences among individuals such as age, sex, or morphology. However, growing evidence suggests that individual diet variation is also common among seemingly identical individuals within populations. This phenomenon has been termed individual diet...

  • Influences of high severity fire and postfire logging on avian and small mammal communities of the Siskiyou Mountains, Oregon, USA

    Creator:
    Fontaine, Joseph B.
    Abstract:
    High severity fire is a historical and integral disturbance process in coniferous forest types. Compounded disturbances such as multiple fires or post-disturbance management activities are increasingly common, but ecological responses are not well understood and may represent novel types of disturbances. I studied bird and small mammal communities in the...

  • College student novice spreadsheet reasoning and errors

    Creator:
    Hoag, James A.
    Abstract:
    The spreadsheet has become a common technology tool and is now a predominant form of end-user programming. Some of the same features that make spreadsheets excellent tools for ad-hoc development can introduce errors into the final product. Although a variety of research has been performed investigating methods to detect errors...
