Comparing lifespan and life course perspectives on combat exposure and PTSD symptoms in later life : findings from the normative aging study

Creator:: Kang, Sungrok
Abstract:: We examined how the experiences of World War II and Korean War veterans, including prewar, warzone, and postwar factors, affected PTSD symptoms in later life. This dissertation consists of two studies. In Study 1, four different hypotheses from a lifespan approach were examined (King et al., 1996): stress evaporation (only...

Distribution, decay, and quantification of fecal source-tracking markers

Creator:: Green, Hyatt C.
Abstract:: Waterborne fecal contamination poses serious risks to human health and can disrupt aquatic ecosystems. Molecular marker methods are widely used to identify and, in some cases, quantify the sources of contamination and guide management decisions regarding water resource protection. However, methods to detect some likely sources of fecal contamination such...

Climate change impacts on mountain snowpack presented in a knowledge to action framework

Creator:: Sproles, Eric A.
Abstract:: Throughout many of the world’s mountain ranges snowpack accumulates during the winter and into the spring, providing a natural reservoir for water. As this reservoir melts, it fills streams and recharges groundwater for over 1 billion people globally. Despite its importance to water resources, our understanding of the storage capacity...

Petrogenesis of the Steens Basalt : Variation in Source Contributions and Effects of Crustal Passage During the Onset of Columbia River Flood Basalt Volcanism

Creator:: Moore, Nicole E.
Abstract:: Continental flood basalts represent short-lived but immense blasts of mafic magma to the continental crust. The youngest and smallest continental flood basalt worldwide, the Columbia River Basalt, initiated with the eruption of the most mafic member, the Steens Basalt (~16.9 Ma). The Steens Basalt is exposed in southeast Oregon, southwest...

Toxicity and in vitro metabolism of Senecio jacobaea pyrrolizidine alkaloids in the rat and mouse

Creator:: Ramsdell, Howard Scott
Abstract:: Senecio jacobaea (tansy ragwort) is a common weed in the Pacific Northwest that contains toxic pyrrolizidine alkaloids (PAs). Jacobine, the major PA in Senecio jacobaea, was incubated with rat liver microsomes and metabolites were isolated by high performance liquid chromatography (HPLC) and identified by mass spectrometric analysis. Metabolites included a...

Controls on eruption style and magma compositions at Mount Hood, Oregon

Creator:: Koleszar, Alison M.
Abstract:: This study is an effort to characterize the magma sources, plumbing system, and eruptive behavior of Mount Hood, a low-explosivity recharge-dominated volcano in the Oregon Cascades. The three manuscripts in this dissertation make use of melt inclusion data, phenocryst compositions, and whole rock petrology and geochemistry to build a schematic...

Cryptogam communities in forest and steppe ecosystems of Oregon, USA

Creator:: Root, Heather T.
Abstract:: I focus on addressing knowledge gaps relating to management of cryptogams in Oregon's public lands in Pseudotsuga menziesii-Tsuga heterophylla forests on the west side of the Cascade Range and dryland steppe in the Cascade Range's rainshadow. While a great deal of research has illustrated the importance of late-successional forests for...

Drivers of plant community dynamics in sagebrush steppe ecosystems : cattle grazing, heat and water stress

Creator:: Reisner, Michael D.
Abstract:: Sagebrush steppe ecosystems are one of the most widespread but endangered ecosystems in North America. A diverse array of human-related stressors has gradually compromised these ecosystems' resilience to disturbance and invasion by Bromus tectorum (cheatgrass). The role of the foundational shrub Artemisia as a driver of herbaceous community structure and...

Magnetotelluric Studies of Tectonic Systems and Volcanic Areas of North America

Creator:: Bowles-Martinez, Esteban
Abstract:: Magnetotellurics is used in two geologic settings on scales ranging from 1000-km tectonic structures to local features hundreds of meters wide. These areas are the Midcontinent Rift System (MRS) and its related mantle plume in the northern Midwestern United States and Newberry Volcano in central Oregon. The MRS study uses...

Understanding historical events through dress and costume displays in Titanic museum attractions

Creator:: Reeves-DeArmond, Genna F.
Abstract:: The sinking of the RMS Titanic has achieved a difficult feat – it has remained culturally relevant. The dedication of the general public to understanding Titanic is evident in many avenues of popular and consumer culture. For those individuals who did not get enough of the 1997 Titanic movie, there...
