  • The Public’s Perception of Fire Prevention and Communication in the Tonto National Forest

    Creator:
    Lindley, David
    Abstract:
    As the frequency and intensity of wildfires continue to occur in the West, so does the need for measures intended to improve firefighter safety; public safety; and the protection of property, resources, and wildlife. Furthermore, as human activity in the expanding Wildland Urban Interface increases, so does the need for...

  • Harnessing Heterogeneity in Human Gut Microbiome Data

    Creator:
    Tataru, Christine
    Abstract:
    The focus of this thesis is to design, characterize, and apply novel computational methods and molecular systems to interrogate heterogeneous human gut microbiome-related phenomena. In Chapter 2, I design, implement, and characterize a method for embedding co-occurrence patterns derived from massive 16s amplicon datasets. I use this method to 1....

  • Wall-to-Wall Forest Mapping in Southeast and Southcentral Alaska: A New Application of the Gradient Nearest Neighbor Approach

    Creator:
    Irvine, Daniel R.
    Abstract:
    Boreal and temperate biomes host nearly half of the earth’s forested ecosystems. The temperate rainforests of the Pacific coast of North America constitute nearly half of all temperate rainforests on earth. Along the northern extent of this region, the perhumid and sub-polar rainforests of southeast and southcentral Alaska are among...

  • Exceeding the standards: The benefits of place-based environmental education in schools

    Creator:
    Miller, Rebecca W.
    Abstract:
    There is a growing body of research that describes the benefits of place-based environmental education (EE) within the schools, including improved competencies, better interpersonal skills, decreased gaps in social divides, increased pupil engagement in learning, increased community awareness, and increased environmental stewardship. Though the benefits are many, few schools utilize...

  • Investigating the Impact of the Gut Microbiota on Rodent Behavior and their Interaction with Enteroendocrine Cells

    Creator:
    Singla, Priyanka
    Abstract:
    Gut-brain communication consists of bidirectional routes between cognitive centers of the brain and peripheral intestines. This bidirectional communication is the result of the interplay between enteroendocrine cells (EECs), enteric nervous system, central nervous system, the vagus nerve, and our microbiota. Multiple studies have associated gut microbial dysbiosis with neurological disorders...

  • Dosimetric Evaluation of Nasal Cavity Basal Cell Layer during Radiotracer Administration

    Creator:
    Flora, Rigel
    Abstract:
    New delivery methods for radiotracers are constantly being proposed. Two key properties of the delivery method must be analyzed: dose to patient and effectiveness of delivery. In this work, the localized skin dose for intranasal administration of 18F was determined utilizing MCNP code. An anatomically accurate nasal cavity was constructed...

  • Three Essays on the Economics of Habitat and Landscape Restoration

    Creator:
    Nguyen, Tu
    Abstract:
    Natural landscapes around the world have experienced serious loss and degradation, which negatively impacts ecosystem service provision by these landscapes. As a result, there have been serious investments to restore natural capital. However, restoration faces complex trade-offs, such as that between restoration quality, or how closely the restored landscapes resembles...

  • Development of a Fundamental Depth-Dependent Neutron Dosimetry Model

    Creator:
    Anspach, Logan J.
    Abstract:
    Current neutron dosimetry methods rely on the assumption that charged particle equilibrium (CPE) is established within the tissue medium. This maintains that the kinetic energy transferred to the medium (KERMA) is equivalent to absorbed dose. However, this assumption is only valid for large volumes such as the whole body. For...

  • Mining Public Microbiome Datasets to Identify Specific Microbial Taxa Associated with Anxiety-Related Disorders

    Creator:
    Martin, Austin N.
    Abstract:
    Over the last ten years, clinical, pre-clinical and animal studies have shown associations between the microbiota and neurological functions. Recent work by the scientific community on the gut-microbiome-brain axis have revealed that gut dysbiosis and specific microbial taxa are associated with a myriad of neurological conditions, such as autism spectrum...

  • A Deterministic Photon and Electron Dosimetry Model for the Lens of the Eye

    Creator:
    Boozer, David L.
    Abstract:
    The lens dose equivalent (LDE) is a regulatory limit set to protect radiation workers. Current methods for estimating the LDE are specific to beam sources in a vacuum and require interpolating data from tables. A new set of deterministic equations for photon and electron point sources has been developed. These...
