The purpose of this study was to compare two groups of freshmen
entering Oregon State University in the fall of 1970; (1) men and
women who were uncertain about choices of academic majors at the time
of entry, and (2) men and women who were certain about choices of
academic...
In recent years, changes in values have occurred in major elements of the population, most notably among the late adolescents and the college students. That this holds portent for the future was referred to by Revel in WITHOUT MARX OR JESUS when he said, "The American revolution is without doubt...
A seasonal hair-loss syndrome of native deer began to occur in the Pacific Northwest United States in the mid-1990s. Clinical manifestations of the disease typically include large numbers of chewing lice on Columbia Black-tailed deer (Odocoileus hemionus columbianus) and Columbia White-tailed deer (Odocoileus virginianus leucurus). Expenditure of energy responding to...

This qualitative study examines the experiences of Asian American students at a predominantly White institution in the cultivation of their racial identity development with the support of resources and services on campus, specifically an Asian cultural center. Six participants at a large, public research institution in the Northwest region were...
Prairie-oak ecosystems in the Willamette Valley, Oregon have experienced habitat loss and degradation; most of these ecosystems are fragmented into smaller patches. Prairie-oak butterfly species, in the Willamette Valley, have decreased dramatically due to loss or degradation of habitat. More research is needed on sustaining the populations of butterflies in...
This thesis considers the problem of estimating the linear
parameters of generalized linear models (GLM), especially binomial
and Poisson regression models, when the explanatory variable is
subject to measurement error. In this situation, the dependence of
the response variable on the observed explanatory variable cannot
typically be modeled as a...
Data in the form of counts or proportions often exhibit more
variability than that predicted by a Poisson or binomial
distribution. Many different models have been proposed to account
for extra-Poisson or extra-binomial variation. A simple model
includes a single heterogeneity factor (dispersion parameter) in the
variance. Other models that...
The Quotient Method (QM), a laboratory-based risk assessment methodology used by the Environmental Protection Agency to evaluate pesticides for registration and use, has not been thoroughly field-tested and its performance has not always been reliable. My objective was to determine if variation in vegetation structure or diet of exposed animals...
