Adolescent Mental Health and Well-Being: Examining the Role of U.S. Public Education Policy and School Climate

Creator:: Hommel, Annie
Abstract:: This dissertation seeks to contribute to a growing body of research on student outcomes by way of a public health perspective examining the intersection of education policy and adolescent mental health and well-being. The conceptual approach underpinning this project rests on the key theoretical assumption that education policy, shaped at...

The Influence of Microbial Communities on Spatiotemporal Elemental Cycling in Coastal Margins Revealed by Community- and Population-level Genomics and Proteomics

Creator:: Kieft, Brandon P.
Abstract:: Biotic and abiotic processes at continent-ocean interfaces cycle a disproportionate mass of carbon and nutrients relative to their global surface area, and microbial activity is a principal determinant of organic and inorganic matter flux in these transition zones. Most studies using modern high-throughput ‘omics techniques to link microorganisms with costal...

Advancements in the Monitoring of Forests and Quantification of Live Aboveground Biomass Using Moderate Resolution Spaceborne Multispectral Imagery and Synthetic Aperture Radar Data

Creator:: Kilbride, John B.
Abstract:: The objective of this dissertation is to enhance the monitoring of forest ecosystems through the utilization of remotely sensed data to address the exigencies posed by the Anthropocene. On a global scale, rising temperatures and fluctuating precipitation patterns have strained forests and produced shifts in natural disturbance regimes. Additionally, the...

Independent effects of habitat loss and fragmentation on pollination : tropical forest fragmentation alters hummingbird movements and pollination dynamics

Creator:: Hadley, Adam S.
Abstract:: A growing body of work reveals that animal-mediated pollination is negatively affected by anthropogenic disturbance. Landscape-scale disturbance results in two often inter-related processes: (1) habitat loss, and (2) disruptions of habitat configuration (i.e. fragmentation). Understanding the relative effects of such processes is critical in designing effective management strategies to limit...

Navigating food and foes in the savanna : nutrition, infections and spatial ecology in African buffalo

Creator:: Combrink, Hendrik J.
Abstract:: The intricate relationship between wildlife health and the quality of their environment is well established, with technological advances increasing our understanding and aiding the unraveling of underlying mechanisms. Large herbivores require forage of sufficient quality to maintain their condition to reproduce and survive, all while warding off parasites and predators...

All in a DNA's work : conservation genetics and monitoring of the New Zealand endemic Maui's and Hector's dolphins

Creator:: Hamner, Rebecca Marie
Abstract:: The critically endangered Maui's dolphin (Cephalorhynchus hectori maui) and the endangered Hector's dolphin (C. h. hectori) are endemic to the coastal waters of New Zealand, where their primary threat is fisheries-related mortality. The Maui's dolphin is among the most critically endangered cetaceans in the world, with its remnant population primarily...

Purification and properties of the polygalacturonases produced by Fusarium oxysporum f. sp. lycopersici

Creator:: Harman, Gary Elvan, 1944-
Abstract:: This study was undertaken to determine the sorts of polygalacturonases present in the culture filtrate of Fusarium oxysporum f. sp. lycopersici, to purify and characterize these enzymes, and to study any complexes that may form between polygalacturonase and carbohydrate not degraded by the enzyme. The polygalacturonase in culture filtrate consists...

Biaxial bending of concrete members with applications to prestressed concrete power poles

Creator:: Stephens, Charles Talmon
Abstract:: A method of analysis of arbitrarily shaped prestressed concrete members for biaxial bending is given. The stress-strain curve of the concrete is represented by two parabolic segments, and the effects of strain hardening of the steel are included in the analysis. An iterative numerical procedure is used to solve for...

Development of oxide semiconductors : materials, devices, and integration

Creator:: Chiang, Hai Q.
Abstract:: The aim of this dissertation is to develop oxide semiconductors by radio-frequency sputtering for thin-film transistor (TFT) applications. A variety of oxide semiconductors are used as the TFT channel layer, including indium gallium oxide (IGO), zinc tin oxide (ZTO), and indium gallium zinc oxide (IGZO). The variety of materials used...

Eastern filbert blight in hazelnut (Corylus avellana): identification of new resistance sources and high resolution genetic and physical mapping of a resistance gene

Creator:: Sathuvalli, Vidyasagar R.
Abstract:: European hazelnut, Corylus avellana L., is the only economically important nut crop in the family Betulaceae. One of the threats to the hazelnut industry in the Pacific Northwest is the fungal disease eastern filbert blight (EFB) caused by the pyrenomycete Anisogramma anomala. Host genetic resistance to EFB identified in the...
