Measuring the source and magnitude of components of variation has important
applications in industrial, environmental and biological studies. This thesis considers
the problem of constructing confidence intervals for variance components in Gaussian
mixed linear models. A number of methods based on the usual ANOVA mean squares
have been proposed for...
This study examines empirically the relationship of value
orientation to meanspiritedness. Meanspiritedness (a collection of
acts, thoughts and/or attitudes which are intentionally malicious)
was defined and a scoring method was designed. The management
level of self-interest in individuals as indicated by their value
orientation and religious orientation was examined. Additionally,...
The emphasis of this work has been in two areas of optical materials - the
crystal-chemical development of new optical frequency converters and the synthesis
and study of new hosts for Cr³⁺ luminescence and lasing.
A simple method has been developed to identify promising frequency-doubling
materials containing triangular oxoanions by...
The percentage of the American population who are 65 years old or older is
rapidly increasing, especially the proportion of women. It is becoming crucial to
encourage lifestyle behaviors that will enable senior women to remain in optimal
health. Following the 1990 Dietary Guidelines' recommendations to limit fat intake
and...
Identifying factors related to adolescent sexual activity is an important
issue for health care, education, and public policy. This research explores the
idea that sexual identity relates to adolescent sexual activity and the riskiness of
the behavior. Sexual identity is composed of many factors, including self-esteem,
sexual self-efficacy, body image,...
This qualitative study examined organizational change including the
necessary steps that a large school district took in planning and implementing a
reform effort. This project told a story of one school district's experience.
The study covered a five year period from 1990 to 1995 in the 30,000 student
Salem-Keizer School...
Attention has been drawn to the observation that environmental benefits under the current regulatory approaches are diminishing with respect to increased pollution control costs. Regulators have begun to appreciate that while environmental gains can still be achieved under the current command and control system, the most significant environmental gains have...
Female mink (Mustela vison) are highly sensitive to polychlorinated biphenyl (PCB)-induced reproductive impairment. The goal of this research was to develop a better understanding of the mechanism of PCB-induced effects on female mink, mink embryos, and surviving mink kits. Anestrous, juvenile female mink and pregnant, adult mink were exposed to...
A method has been developed for the continuous automated monitoring
of cardiac output in adult rainbow trout. Average cardiac output measured under
control conditions and varied environmental conditions of hypoxia and post-hypoxia
was significantly higher (P≤ 0.05) in male than female trout. The cardiac
output of trout in spawning condition...
