  • Women initiated solutions for HIV prevention (WISH study): factors associated with intentions to use microbicides and Tenofovir

    Creator:
    Kandathil, Sonia M.
    Abstract:
    With women comprising nearly 50% of HIV/AIDS infections globally, the development of new woman-initiated HIV prevention methods has become a public health imperative. To date, the female condom and the diaphragm are the only woman-initiated prevention methods available on the consumer market. Recent research has focused on two HIV/AIDS prevention...

  • Wind-current Interactions of the Sri Lanka Dome and Tropical Indian Ocean

    Creator:
    Cullen, Kerstin
    Abstract:
    The southwest monsoon, which may be idealized as the northward movement of the intertropical convergence zone in the Indian Ocean associated with differential heating of land and ocean, brings a seasonal reversal of currents and winds in the Bay of Bengal and the Arabian Sea. Atmospheric convection from monsoon activity...

  • Wildfire risk management : strategic interaction and spatial interdependence

    Creator:
    Busby, Gwenlyn M.
    Abstract:
    In this dissertation, I examine how the spatial configuration of forest ownership influences the risk-mitigating behavior of public and private forestland owners over time. I determine whether or not the predicted equilibrium outcomes are socially optimal and, if not, whether the introduction of regulation, liability, or private insurance would lead...

  • Welfare Effects of the Federal Crop Insurance Program : The Sufficient Statistics Approach

    Creator:
    Yu, Jialing
    Abstract:
    The publicly subsidized Federal Crop Insurance Program has expanded rapidly in recent decades in the United States. With the reform in the 2014 Farm Bill, the Federal Crop Insurance Program has become the most important component of U.S. farm policies. The primary goal of the program is to provide risk...

  • Weight stigma consciousness and perceived physical appearance : their key precursors and relationship to health behaviors

    Creator:
    Concepcion, Rebecca Yahnke
    Abstract:
    The purpose of this study was to explore the relationships between weight stigma consciousness, perceived body appearance, social physique anxiety, and the health outcomes of physical activity levels and eating behaviors. Select precursors were also examined. These relationships were based on Harter's model of self-worth. Two-hundred fifteen adults with a...

  • Weak-supervision Time-series Analysis

    Creator:
    You, Zeyu
    Abstract:
    Efficient time-series analysis can impact multiple application domains such as motif discovery in gene analysis or music data, extracting spectro-temporal patterns in acoustic scene analysis, or annotating and classifying electrical bio-signals (such as ECG, EEG, and EMG) for medical applications. Time-series analysis involves a variety of tasks. To predict future...

  • Waving Arms to Teach & Learn Quantum Mechanics

    Creator:
    Hahn, Kelby T.
    Abstract:
    In this dissertation I explore the Arms representation and activities for teaching quantum mechanics invented at Oregon State University. In the Arms representation students embody quantum states. The Arms activities are presented as an exemplar of the unique physics classroom culture of the upper-division Paradigms in Physics program. In the...

  • Water scarcity and reservoir reliability in basins affected by climate and land use change : impacts of hydrogeology, sensitivities, and uncertainties in the Santiam River Basin, Oregon

    Creator:
    Mateus, M. Cristina
    Abstract:
    Multipurpose management of hydrosystems face a number of uncertainties related to hydrologic variability and nonstationarity. Anticipated air temperature increases in the Pacific Northwest region are projected to alter the timing and quantity of streamflow associated with precipitation shifting from snow to rain, including shorter winter runoff periods, earlier spring runoff,...

  • Water and solute transport : modeling and application to water conservation in layered soil

    Creator:
    Mohammed, Fareed H. A. N.
    Abstract:
    Sandy soils are among the least productive soils because of their inability to store adequate water for plant growth. Their high percolation rate not only allows water to move quickly beyond the root zone, but also washes nutrients below the reach of plant roots. High evaporation occurs from the soil...

  • Wasserstein β-Diversity Metrics over Graphs: Derivation, Efficient Computation and Applications

    Creator:
    McClelland, Jason
    Abstract:
    Microbial ecology has been transformed by metagenomics, the study of the genetic in-formation in entire communities of organisms. In the following we develop metagenomic tools arising from the classic Wasserstein metric as applied to questions regarding the diversity between microbial communities. We provide a novel proof of the characteriza-tion of...
