  • Parameter estimation of Gaussian hierarchical model using Gibbs sampling

    Creator:
    Mbuthia, Juliana
    Abstract:
    Gibbs sampling method is an important tool used in parameter estimation for many probabilistic models. Specifically, for many scenarios, it is difficult to generate high-dimensional data samples from its joint distribution. The Gibbs sampling provides a way to draw high-dimensional data via the conditional distributions which are typically easier to...

  • Spatiotemporal Assessment of Crop Histories in the Pacific Northwest

    Creator:
    Kumbhakar, Ishika G.
    Abstract:
    The cultivated potato (Solanum tuberosum) is one of the most important food crops in the United States, as well as globally. As demand rises, growers in the Pacific Northwest are revisiting their crop management strategies to determine whether there are additional ways to enhance crop productivity while managing plant and...

  • Ascorbylation- the biological relevance of covalently bound ascorbic acid

    Creator:
    Kesinger, Nicholas G.
    Abstract:
    Ascorbic acid, or vitamin C, is well known as a co-factor for proline-hydroxylase and as an anti-oxidant. However, it is also capable of forming covalent bonds, particularly in the role of a nucleophile, henceforth termed 'ascorbylation'. The ascorbylation of electrophiles can occur under physiological conditions. Furthermore, there are a number...

  • "Legality" on Hold: An Exploratory Study on DACAmented Student’s Experiences of Uncertainty and Fear

    Creator:
    Kingsley, Rachel C.
    Abstract:
    The purpose of this study is to explore the uncertainty and fear that DACAmented college and university students experience with the potential termination of the United States Deferred Action for Childhood Arrivals (DACA) program. There is limited research on the experiences of DACAmented individuals during this time of uncertainty for...

  • Expectations and Lived Realities of Iraqi Women Refugees and Refugee Mental Health Providers in Portland: An Ethnographic Study to Inform Refugee Mental Health Services and Policy

    Creator:
    Eiwaz, Massarra Adnan
    Abstract:
    Distress among resettled refugees in the U.S. consistently reflects refugees’ experiences of discrimination, re-traumatization, gaps in healthcare services, and disrupted expectations and lived-realities. This thesis aims to fill a critical need for ethnographic studies investigating how recent anti-immigrant, -Muslim, and -Arab rhetoric and policies combine with chronic gaps in services...

  • Diversity and Impact of Soft Rot Pathogens of Potato in the Columbia Basin

    Creator:
    Brazil, Jessie A.
    Abstract:
    Bacterial soft rot of potato (Solanum tuberosum), caused by Pectobacterium and Dickeya species, is among the most common and destructive potato diseases in the United States. These pathogens cause a variety of vascular wilts, and in potato cause a disease complex that includes tuber soft rot, blackleg, aerial stem rot,...

  • Exploring Intuitive Use

    Creator:
    Cairns, Tylee
    Abstract:
    The term "Intuitive use" has become a common phrase to describe interfaces and products, however it is rarely defined. Research regarding intuitive use is in its infancy, beginning primarily in 2003. With the development of new terms in Human Factors and Human-Computer Interaction, it is important for Designers and Users...

  • Structural Similarities and Differences in Tropone and Tropolone: Gas-Phase Electron Diffraction Study

    Creator:
    Titus, Eric J.
    Abstract:
    The method of gas-phase electron diffraction is a very useful tool for determining the geometry of a molecule in the gas-phase to a high degree of accuracy. In this thesis, the structures of tropone and tropolone, which are similar molecules that are both based on a 7-carbon ring, were investigated...

    Creator:
    Li, Yong J.
    Abstract:
    Metal Organic Framework (MOF) materials, consisting of metal ions with organic linkers, have a functional cavity structure which can be utilized in applications such as catalyst, micro sensing, and gas absorption. Due to MOF materials' selective gas adsorption property, interest in MOF materials has intensified in the last few years,...
