The GED certificate as a credential for entry into and retention in the workforce : recipient and employer perceptions

Creator:: Mason, Roy B.
Abstract:: The purpose of this research was to assess the use of the General Educational Development Tests (GED) as an alternative high school credential in Oregon. A study was conducted of 469 Oregon GED recipients' and 646 private sector employers' perceptions of the GED. Both quantitative and qualitative measurements were used...

A comparison of braille and compressed speech as learning modes for legally blind adults

Creator:: Hughes, Colleen Constance Carris
Abstract:: The primary purpose of this research study was to determine whether significant differences occurred in the amount of knowledge achieved as a result of using Braille or compressed speech as learning modes. Biographic/demographic characteristics such as present age, highest educational level achieved, age at loss of vision, age at initial...

Disease invasion dynamics : brucellosis and tuberculosis in African buffalo (Syncerus caffer)

Creator:: Gorsich, Erin E.
Abstract:: Emerging infectious diseases in wild animals threaten global biodiversity as well as domestic animal and human health. Their unprecedented increase in conjunction with anthropogenically induced range shifts of endemic pathogens exposes hosts to novel parasite combinations, lending urgency to research on disease dynamics in wildlife systems. In natural populations, hosts...

Host-Induced Gene Silencing in Black Cottonwood for Control of Septoria Canker: Efficacy and Non-Target Impacts

Creator:: Gordon, Michael I.
Abstract:: Septoria canker remains the most important disease of poplars in intensively managed forest plantations. Genetic resistance has long been considered the best way to manage for this disease. Transgenic resistance mediated by RNA silencing against pathogens and pests (HIGS: host-induced gene silencing) has shown promise in other pathosystems but has...

Characterizing an Annual Grass Invasion and Its Link to Environmental and Disturbance Factors Using Remote Sensing: New Tools and Applications

Creator:: Nietupski, Ty C.
Abstract:: The spread of nonnative species across the globe has contributed to biodiversity loss and changes in ecosystem structure and function. Monitoring the introduction, naturalization, and spread of introduced species is critical in abating negative impacts wrought by species invasions. However, providing basic information concerning the presence or spread of many...

Metagenomics, barcoding, and metabarcoding statistical analysis to facilitate integrative genomic studies of microbial and eukaryotic assemblages

Creator:: Senn, Savanah
Abstract:: The body of work aims to contribute to the area of Quantitative analysis in Environmental Sciences, and is focused on the microbiome. The underlying theme for the dissertation is methods and workflow. The unique bioinformatics workflow used for the analysis of genomic data was used to answer distinct and pressing...

Small Unmanned Aircraft Systems (UAS) for Engineering Inspections and Geospatial Mapping

Creator:: Javadnejad, Farid
Abstract:: Small unmanned aircraft systems (UAS) carrying consumer-grade nonmetric cameras are increasingly utilized to generate high-resolution 3D geospatial data. Low cost, ease of operation, widespread availability and low altitude maneuvering capabilities of UAS, as well as the rapid development of technology and methods, make UAS-based photogrammetry applicable to many civil engineering...

Coastal Dune Ecology, Geomorphology, and Ecosystem Services : How Invasive Beachgrasses, their Interactions, and Sediment Dynamics Shape U.S. Pacific Northwest Dunes

Creator:: Biel, Reuben G.
Abstract:: Biological invasions and climate change represent two preeminent threats to ecological communities and biodiversity, altering the distribution and abundance of species, disrupting existing species interactions and forming unprecedented ones, and creating novel ecological communities. Many of the most successful invasive species are also ecosystem engineers, species that physically modify the...

A revision of the genus Notiphila Fallén (Diptera:Ephydridae) from America north of Mexico

Creator:: Mathis, Wayne N.
Abstract:: The North American species of the shore fly genus Notiphila Fallen were taxonomically revised. Over 13,000 specimens were examined from throughout the Nearctic Region and information relating to the biology of many species occurring in the West was gathered from both field and laboratory studies. Previously used characters were reevaluated;...

Two zoogeographic studies of deep sea benthic gammarid amphipods

Creator:: Dickinson, John J. (John Joseph), 1946-
Abstract:: Two separate studies on the distribution of gammarid amphipods in the bathyal and abyssal benthic environments demonstrated that different assemblages could be found at a single depth over distances on the order of 100 kilometers. These studies evaluated changes in the species composition and relative abundance of the amphipod assemblage...
