The primary goal of this study is to assess the impact of a subduction component
added to the mantle wedge beneath the Oregon Cascades to the composition and fO2 of
primitive Cascade basalts. Olivine-hosted melt inclusions from compositionally diverse
basalts across the Cascade arc (~100 km) are utilized in an...
Previous attempts to understand the factors affecting the energetic cost of locomotion have found a direct link between the energetic cost and the mechanical work done during periods when the limb is in contact with the ground. However, when the limb is not in contact with the ground during the...
The fungus Cochliobolus victoriae causes Victoria blight of oats and Arabidopsis and is pathogenic due to its production of a compound called victorin, which induces programmed cell death in sensitive plants. Victorin sensitivity in Arabidopsis is conferred by the dominant gene LOCUS ORCHESTRATING VICTORIN EFFECTS1 (LOV1), which encodes a coiled-coil-nucleotide...
This dissertation is concerned with the diminution of Oregon's Umatilla Indian Reservation over a 120 year period (1855-1975). Its objective is to show that the transfer of land from Indian to non-Indian ownership was most attributable to four casual factors:

A questionnaire was employed to gather data to determine Ii there were differences by gender, academic major, and last year of attendance at OSU among former student leaders In: postcollegiate...
In recent years, log structures have been marketed as an alternative
to conventional light-frame wood structures. Log structures are constructed
using round timbers (or manufactured timbers) that are stacked vertically
and have interlocking corners. Thru-rods and lag screws are used to
provide inter-log connections. This project was conducted to evaluate...
Balancing resource extraction with protection of Pacific Northwest forest ecosystems requires understanding the population biology of ectomycorrhizal fungi. Design of landscape-scale management and research strategies requires understanding genet size, habitat requirements, and dispersal capabilities. The purpose of this dissertation was to gain knowledge about the distribution of genetic variation, systematics,...
The purpose of this study was to clarify the relationship between religiosity and sexual behavior of college students by using a measure of religious orientation to define religiosity. Religious orientation refers to individuals' motivations for religious involvement and personal faith. Religious orientations are characterized as being extrinsic, intrinsic, indiscriminately proreligious...
The purpose of this study was to investigate the relationship between moral development and year in school, gender, and personality type for university undergraduates. Moral development was measured by the Defining Issues Test (DIT) and personality was assessed using the Myers-Briggs Type Indicator (MBTI). The sample consisted of 320 freshmen,...
