Creator:: Scott, Sophia L. M.
Abstract:: Intimate partner violence is the systematic, intentional use of physical, emotional and/or sexual abuse that one person in a domestic relationship exerts over their partner in order to maintain power and control. In our society, we tend to focus on the external evidence of intimate partner violence such as the...

Investigating the age-related loss of endoplasmic reticulum stress response

Creator:: Fallahi, Anahita
Abstract:: The endoplasmic reticulum (ER) is a crucial organelle in the cell where protein folding and processing occurs, and conditions that negatively affect ER functions are highly detrimental to the cell. The accumulation of unfolded/misfolded proteins in the ER leads to a condition known as ER Stress. The ER has developed...

Computing occupation times with integral equations

Creator:: Meredith, Nick
Abstract:: Consider a simple Markov process on [0,T]. The occupation times were extensively studied in the case of T increasing to infinity. Here we develop a method of computing the distribution for occupation times when T is small via integral equations and integral transforms.

A multi-faceted method for validating emotional intelligence

Creator:: Reyna, Nicholas R.
Abstract:: The Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) purports to assess emotional intelligence, which includes the ability to successfully identify and manage emotions. To test the validity of this claim, 21 students took the MSCIET along with a several other performance measures and personality scales, and their scores were correlated. The MSCEIT...

Financial reporting and the business environment : a comparison of the United States and Mexico

Creator:: Wolfer, Robert J.
Abstract:: Multinational corporations must be aware of the business and financial reporting issues that await them abroad. Investors also must have this knowledge in order to adequately interpret the financial information they receive from these companies. This study compares and contrasts the business environments in the US and Mexico, with a...

You Can’t Beat the Clock: Oxidative Stress and period Mutants in Drosophila melanogaster

Creator:: Davis, Andrew J.
Abstract:: The free-radical theory of aging proposes that intracellular accumulation of oxidative damage caused by reactive oxygen species (ROS) is responsible for the process of senescence. ROS are produced during normal aerobic metabolism and have been shown to cause numerous cellular and sub-cellular defects that lead to termination of the cell...

Localization of the CB1 receptor in the brain of Taricha granulosa

Creator:: Aubert, Jolene E.
Abstract:: The psychoactive component of marijuana, A9-tetrahydrocannabinol (THC), is known to have effects in humans that are mediated by the cannabinoid receptor (CB 1). Although a great deal of research has been done to confirm the interaction of exogenous cannabinoids with the CB 1 receptor, little is known about the receptor's...

Physiological responses of cyanolichens to photosynthetic partners

Creator:: Bichel, Govardhana Puja
Abstract:: While previous experiments on the physiological activity of primary and secondary cyanolichens have been done, an analysis of photomorphs has never been attempted. Photomorphs of Peltigera britannica (Gyelnik) Hotan-Hartw. & Tonsberg were studied to compare the physiological response of a primary cyanolichen to an additional symbiotic partner (green algea) while...

Prediction of lambing number in mid and late-gestation ewes by fecal hormone analyses

Creator:: Davis, Sara Kristin
Abstract:: Previous research suggests a link between litter size in ewes and differential excretion of fecal hormones. An accurate test for fetal number would be useful to sheep producers and a fecal hormone response could be utilized in such a test. Fifteen previously categorized fecal hormones were analyzed within fecal samples...

Micropropagation of Douglas fir (Pseudotsuga menziesii) in a double-phase culture medium

Creator:: Gross, Leah M.
Abstract:: The timber and Christmas tree industries are important components of the Pacific Northwest economy. A goal of both industries is to produce high quality trees with high growth rates. Accomplishing this requires increased genetic quality of the trees grown. Tissue culture provides the most promise for propagating these superior genotypes....

The effects of nitrogen, tillage and irrigation on the color of Willamette Valley Pinot noir wine

Creator:: Helms, Kelly L.
Abstract:: Various vineyard practices influence the quality of a wine. In 1999, three levels of nitrogen (N), two levels of tillage and two levels of irrigation were applied to Pinot noir grape cultivars at Benton Lane Vineyards in the Southern Willamette Valley. N treatments were zero, soil and foliar applications. Every...

Direct-seeded cucurbit cultivation in Oregon and tropical South America

Creator:: McCombs, Avery
Abstract:: Cucurbits are grown in production agriculture in Oregon as well as in smallholder agriculture in tropical South America. Experimental research was performed at the OSU Research Farm in 2001 with direct-seeded cucurbits, and literature reviews were conducted to develop a characterization of smallholder farming in tropical South America. The two...

The effects of the phosphatase inhibitor, okadaic acid, on plasminogen activator expression in bovine oocyte-cumulus cell complexes

Creator:: Peoples, Mike
Abstract:: Plasminogen activators (PAs) have been implicated in: ovulation, oocyte maturation, fertilization, implantation, and many other reproductive activities. Three pathways have been implicated in the activation of the PA regulatory system. These include the conventional PKC and cAMP-dependent signaling pathways, and also an independent pathway thought to be regulated by protein...

Invasion of Brachypodium sylvaticum in prairie and forest habitats : differences in community structure between uninvaded and invaded systems in Bald Hill Park, Corvallis, Oregon

Creator:: Goodell, Whitney
Abstract:: Brachypodium sylvaticum (Huds.) Beauv. is an invasive grass that can be found in forest and prairie communities throughout the Willamette Valley, Oregon. It can out-compete native species of grasses and forbs and become dominant in a broad range of habitats. This study investigated if there were differences in vegetation structure...

Comparing Native Oral History and Scientific Research to Produce Historical Evidence of Native Occupation During and After the Missoula Floods

Creator:: Woodside, Gail J.
Abstract:: The Missoula Floods occurred approximately fifteen thousand to thirteen thousand years ago during the last ice age. The floods occurred when waters held back by a finger of the Purcell Ice Lobe gave way allowing water which covered present day Missoula, Montana to inundate areas of Idaho, Washington, and Oregon....

Characterization of the Ovine Prolactin Promoter

Creator:: Tan, Taralyn
Abstract:: Approximately five to eight percent of domestic rams demonstrate a sexual attraction towards other rams, directing no sexual behaviors towards estrous ewes. It has been observed that these male-oriented rams (MORs) have a greater abundance of prolactin mRNA than female-oriented rams in the medial preoptic area of the anterior hypothalamus...

A Genome-Wide, Phenotypic Screen for Genes Regulating Quorum Sensing in Pseudomonas aeruginosa

Creator:: Gobble, Timothy Robert
Abstract:: The opportunistic pathogen Pseudomonas aeruginosa possesses two LuxR-LuxI type quorum-sensing systems that use diffusible acyl-homoserine lactone molecules to autoinduce and coordinate expression of multiple virulence factors. We conducted a highthroughput screen for mutants deficient in skim-milk proteolysis—a quorum-sensing dependent phenotype—using a nonredundant transposon-insertion library representing most nonessential genes in P....
