  • You are What, When, Where, and How you Eat : Mercury in Avian Food Webs across Multiple Spatial Scales

    Creator:
    Jackson, Allyson K.
    Abstract:
    Human alterations of landscapes take many forms, one of which is anthropogenic pollution. Mercury (Hg) is a complex contaminant because its uptake into the food web is not driven entirely by loading to the system; methylation is necessary to make Hg bioavailable and toxic to fish and wildlife. Because methylation...

  • 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...

  • 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...

  • Wide band gap semiconductors and insulators : synthesis, processing and characterization

    Creator:
    Hersh, Peter A.
    Abstract:
    The work presented here is focused on applying basic principles of solid-state chemistry to the study and development of new wide band-gap semiconductors and insulators for photovoltaic and electronic-device applications. Analysis of crystal structure, band structure, optical band gap, morphology and transport properties provides fundamental insight into materials performance as...

  • White principals examine power, privilege, and identity : the challenge of leading for equity

    Creator:
    McCann, Julie McLaughlin
    Abstract:
    The purpose of this qualitative study was to examine the experience of white principals in understanding their white identity, privilege, and power as they worked to implement socially-just and culturally proficient schools. The findings offer insights into the following questions: 1) How do white school leaders view white identity and...

  • Where have all the women and children gone? An examination of domestic life at the Newell Farmstead (35MA41) in the early Oregon country

    Creator:
    Manion, Mollie Jo
    Abstract:
    The Newell Farmstead (35MA41) archaeological site lies in the heart of the French Prairie in the Willamette Valley in the Champoeg State Heritage Area, Oregon. The integrity and depth of deposition have made the Newell site a unique opportunity to look at activity areas and domestic life of early Euro-American...

  • 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...

  • Watershed response to western juniper control

    Creator:
    Deboodt, Timothy L.
    Abstract:
    Western juniper (Juniperus occidentalis) encroachment has been associated with increased soil loss and reduced infiltration resulting in the loss of native herbaceous plant communities and the bird and animal species that rely on them. Hydrologically, however, change in water yield has been linked with the amount of annual precipitation a...

  • 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...

  • Volatile mobility of trace metals in volcanic systems

    Creator:
    Loewen, Matthew W.
    Abstract:
    Semi-volatile trace metals like Li, Cu, Mo, Sn, In, and Pb have the potential to track mobility of a volatile phase in volcanic systems. In this dissertation four studies are presented that either directly investigate or are motivated by observations of trace metal behavior in volcanic systems. A common tool...
