Evaluating safety at Oregon‘s isolated, high-speed, signalized intersections

Creator:: Kopper, Neil H.
Abstract:: Isolated approaches at signalized intersections with posted speed limits of 45 mph or greater generally experience large numbers of rear-end and angle collisions. A combination of less attentive drivers, high operating speeds, and less than ideal intersection characteristics can result in crash frequencies well above expected rates. A number of...

Beyond high hopes : educational attainment among children of immigrants

Creator:: Feeney, Sarah L.
Abstract:: In light of broadening racial/ethnic educational attainment gaps, growing diversity within young populations, and the increasingly critical relationship between higher education and outcomes in adulthood, understanding the factors that shape educational attainment is an especially important task for research. With this goal in mind, the current study examined how national...

Development and validation of a fatigue reliability method for bridging materials

Creator:: Gallops, Sarah
Abstract:: Toughened ceramics, or bridging ceramics, are being developed in an attempt to widen the application base of traditional ceramics, which are brittle and have low resistance to crack extension. The crack growth resistance of these extrinsically toughened ceramics has been shown to increase with crack length, and unlike traditional ceramics,...

Pathogenicity of Phytophthora species from Oregon waterways

Creator:: Navarro, Sarah M.
Abstract:: Described as one of the most destructive pathogens of agricultural crops and forest trees, Phytophthora is a genus of microorganisms containing over 100 known species. Phytophthora alni has caused collar and root disease in alders throughout Europe and a form of the species has recently been isolated in North America....

Effects of earthflows on stream channel and valley floor morphology western Cascade Range, Oregon

Creator:: Vest, Sarah B.
Abstract:: Slow moving earthflows (0.1 15 m/yr.) may constrict valley floors and directly impinge on stream channels. Earthflows that move laterally into channels deliver organic and inorganic material to the stream from the earthflow toe. If the amount and particle size of this material is too large to be removed by...

Factors affecting the Ceratomyxa shasta infectious cycle and transmission between polychaete and salmonid hosts

Creator:: Bjork, Sarah J.
Abstract:: Ceratomyxa shasta is a myxozoan parasite that infects salmonid fishes causing the disease ceratomyxosis that is characterized by severe hemorrhage and necrosis of the intestine and death of the fish host. Ceratomyxa shasta is endemic to the Pacific Northwestern United States and Canada, where epizootics are reported for both wild...

Effects of spatial scale and heterogeneity on avian occupancy dynamics and population trends in forested mountain landscapes

Creator:: Frey, Sarah J. K.
Abstract:: Population trends and patterns in species distributions are the major currencies used to examine responses by biodiversity to changing environments. Effective conservation recommendations require that models of both distribution dynamics and population trends accurately reflect reality. However, identification of the appropriate temporal and spatial scales of animal response, and then...

The marine geomorphology of American Samoa : shapes and distributions of deep sea volcanics

Creator:: Roberts, Jed T.
Abstract:: The geologic processes at work in American Samoa have long been a point of scientific debate. Of its numerous volcanic formations, few breach sea level, leaving an enormous proportion of their mass unavailable to traditional observation. This study aims to describe the deep sea geomorphology of American Samoa through compilation,...

Higher-level Analysis of RNA-Seq Experiment: Multiple Data Sets and Multiple Genes

Creator:: Zhuo, Bin
Abstract:: Differential expression (DE) analysis is a key task in gene expression study, because it uncovers the association between expression levels of a gene and the covariates of interest. This dissertation pertains to two particular aspects of DE analysis—identifying stably expressed genes for count normalization and accounting for correlation between DE...
