Constraints of the origin of the middle Pleistocene transition from the glacial sedimentary record of the north-central United States

Creator:: Roy, Martin
Abstract:: This dissertation focuses on the role of ice sheets in the transition during the middle Pleistocene (-1.2 Ma) from 41-kyr glacial cycles to 100-kyr glacial cycles. This research evaluates the hypothesis that the middle Pleistocene transition (MPT) was related to the glacial erosion of a regolith mantle and the subsequent...

Host plant dependent disease progression of the microsporidian parasite Nosema tyriae on Cinnabar moth larvae

Creator:: Berns, Kathryn, Buergi, Linda, and McEvoy, Peter
Abstract:: Tyria jacobaeae was introduced as a biological control agent to control the noxious weed Jacobea vulgaris. Eventually introduced to the Cascade mountain range of Oregon, T. jacobaeae has been found to feed on Senecio triangularis, a native plant closely related to J. vulgaris. Nosema tyriae is a parasitic fungus under...

Past climate variability in southwestern Oregon and relationships with regional and hemispheric climate

Creator:: Ersek, Vasile
Abstract:: This dissertation presents the results of three studies that assessed climate variability on short and long timescales in western United States. The growth of carbonate formations in caves (speleothems) is used to infer the timing and amplitude of past climate variability. We first assess the controls on speleothem growth for...

Inelastic scattering of 17-MeV protons from ¹⁴N and ¹⁵N

Creator:: Rogers, Charles William
Abstract:: An inelastic scattering experiment was done in which 17-MeV protons from the Oregon State University cyclotron were scattered from ¹⁴N and ¹⁵N gas targets. Angular distributions are shown for the ground, 6.32-, 7.56-, 8.31-, and 8.57 -MeV states and the 5.3- and 7.2-MeV unresolved doublets of ¹⁵N, and for the...

Biotic barriers to colonizing new hosts by the cinnabar moth Tyria jacobaeae (L.)(Lepidoptera: Arctiidae)

Creator:: Karacetin, Evrim
Abstract:: The cinnabar moth (Tyria jacobaeae (L.), Lepidoptera: Arctiidae) is an icon in population ecology and biological control that has recently lost its shine based on evidence that (1) it is less effective than alternatives (such as the ragwort flea beetle Longitarsus jacobaeae (Waterhouse) (Coleoptera: Chrysomelidae) for controlling ragwort Senecio jacobaea...

The Art of Reducing Coastal Hazard Complexity: Coupling Physics and Probability to Understand Extremes, Variability, and Climate-dependence

Creator:: Anderson, Dylan L.
Abstract:: Coastal hazards are the result of numerous physical processes cumulatively causing water levels to flood and erode the land. The waves, storm surges, tides, and run-off contributing to elevated water levels are each the product of chaotic and random weather patterns. These stochastic weather patterns dissipate energy in Earth's climate...

An Interdisciplinary approach towards understanding late Pleistocene ice sheet change

Creator:: Cuzzone, Joshua K.
Abstract:: The results presented in this dissertation address a number of questions regarding late Pleistocene and Holocene ice-sheet and climate interactions, spanning disciplines involving paleoclimatology and atmospheric science. These studies use various techniques in geochemistry, climate modeling, and ice-sheet modeling to address ice- sheet response to climate and the attendant interactions...

The application of John Rawls' principles of justice to health care distribution in the United States

Creator:: Wetle, Victoria L.
Abstract:: The principles of justice developed by John Rawls and articulated in his work A Theory of Justice, published in 1971, were used as the evaluative tool in assessing health care distribution in the United States. A model for using Rawls' theory was developed emphasizing the role of the 'least advantaged'...

Balance Sheet Classification Shifting and Non-Articulation

Creator:: Wang, Dilin
Abstract:: Research strongly suggests non-articulation is an effective indication of the reporting quality of both the cash flow statement (Gong et al. 2014) and income statement (Collins et al. 2015). I complete the financial reporting circle by examining the association between non-articulation and the reporting quality of the balance sheet, captured...

Regional scale sandbar variability : observations from the U.S. Pacific Northwest

Creator:: Di Leonardo, Diana R.
Abstract:: Understanding sandbar dynamics and variability is integral to developing a predictive capacity for nearshore flows, sediment transport, morphological change, and ultimately for determining coastline exposure to damaging storm waves. Along the high-energy U.S. Pacific Northwest (PNW) coast, sandbars typically dominate the bathymetry of the active zone. Here we report on...
