Adult 4-H volunteer empowerment in 4-H youth development settings

Creator:: Olsen, Pamela
Abstract:: The primary purpose of this study was to determine which factors related to adult 4-H volunteer empowerment in 4-H youth development settings. This study examined the relationship of adult 4-H volunteers’ perceived leadership styles of Oregon 4-H Youth Development Educators (YDE) to the adult 4-H volunteer sense of empowerment. In...

Mass Spectrometry-based Analysis of Superwarfarins and their Metabolites and the Investigation of Novel Treatments for Poisoned Victims

Creator:: Nosal, Daniel Grzegorz
Abstract:: Superwarfarins are anticoagulant rodenticides that are 100 times more potent and 15 times more persistent than warfarin. They have been used since the 1980s and cause over 10,000 cases of accidental and intentional poisonings per year. Apart from inducing uncontrollable bleeding, by inhibiting the vitamin K cycle, superwarfarins can disrupt...

Petrologic Investigations into the Magmatic Processes That lead to Au, Ag, and Base Metal Fertility: Insights from Pebble, Alaska and the Emigrant Pass Volcanic Field, Nevada

Creator:: Olson, Nansen H.
Abstract:: Magmatic-hydrothermal ore deposits are giant geochemical anomalies in the earth’s crust most often generated by normal magmatic terrestrial processes. They are often associated with oxidized and hydrous intermediate to highly evolved magmas that have concentrated metals and have the necessary components to efficiently extract and transport them as ascending magmatic-hydrothermal...

Tsunami Loading on Coastal Infrastructure

Creator:: Xie, Zhongliang
Abstract:: The safety of coastal infrastructure has been a concern after the Indian Ocean Tsunami in 2004 and the Great East Japan Tsunami in 2011. The western coast of the United States is also exposed to tsunami hazards due to the Cascadia subduction zone. Therefore, it is critical to design coastal...

Chemical and Genetic Investigations of Toxic Freshwater Cyanobacterial Blooms for Improved Monitoring and Understanding of Lake Ecology

Creator:: Collart, Lindsay P.
Abstract:: Toxin production by cyanobacterial harmful algal blooms (cyanoHABs) in freshwater systems has lasting ecological and human impacts. Nutrients, light availability, hydrology, and microbial community composition impact the frequency and intensity of toxic cyanoHABs. Climate change will exacerbate toxic cyanoHABs, making real time and predictive monitoring a vital tool for managing...

Computational Investigation and Prediction of Mechanisms and Stereocontrol in Complex Organic Reactions

Creator:: Pattawong, Ommidala
Abstract:: Complex organic transformations, such as the addition of pyrrole to ketene using planar chiral organocatalyst (*PPY), the four-component anhydride- Manniach reactions, and the site-selective desymmetrization of meso-1,2-diol, are remarkable synthetic reactions that provide high yield and high selectivity. However, the exact mechanism and origins of stereocontrol for theses synthetic organic...

Accumulation and effects of 4-nonylphenol in chinook salmon fry and their estuarine amphipod prey

Creator:: Hecht, Scott A.
Abstract:: 4-nonylphenol (NP), a surfactant degradation product, is an unregulated, ubiquitous aquatic contaminant and endocrine disruptor, for which aquatic life criteria are currently under development by U.S. EPA. The effects of NP on estuarine amphipods and chinook salmon fry were investigated, and this dissertation reports research into the impacts of NP...

Quantitative Tools for Monitoring Strategy Evaluation and Assessment of Sea Turtle Populations

Creator:: Piacenza, Susan E. H.
Abstract:: Green sea turtles, Chelonia mydas, have endangered and threatened populations globally, but several populations show signs of population recovery. In Hawaii, nesting female green turtles have increased 5.7% year⁻¹ since 1973, but wide fluctuations in census counts of nesting females make recovery diagnosis difficult. For effective management planning, it is...

Drivers and Impacts of a Recent Annual Grass Invasion: Ventenata dubia and Fire in the Inland Northwest

Creator:: Tortorelli, Claire M.
Abstract:: Biological invasions threaten native biodiversity, alter ecosystem function, and are a major cause of economic losses across the planet. The most impactful invaders alter disturbance regimes and initiate state shifts to outside the historical range of variability of the ecosystem. Concern for ecological and economic losses has prompted a rapid...
