The Calapooia River, a major tributary of the Willamette River in western Oregon, is a watershed typical of many found in the Willamette Basin. Public and private forested lands occur in the steep Upper Zone of the watershed, mixed forest and agriculture lands are found in the Middle Zone, and...
The purpose of the study was to identify and examine critical factors that either promote or hinder acute care hospitals decision-making on adopting complementary and alternative medicine (CAM). All acute care hospitals in the states of Oregon and Washington were included in the study. Individual interviews were conducted at the...
The regulation of behavior is a major issue in early childhood development, with important implications for children’s adaptive and maladaptive developmental outcomes. Emerging research suggests that the degree of successful self-regulation depends upon the efficiency of the child’s attentional system and that the ability to focus and sustain attention supports...
Forced removal of Indigenous communities and subsequent colonial forest management have led to landscape homogenization, fuel abundance, conifer encroachment, and, therefore, a loss of forest and fire resilience in the Western US. This loss of forest and fire resilience leads to a loss of social resilience as forested communities struggle...
The constituent materials of concrete often contain chlorides. The presence of chlorides in sufficient amounts can disrupt the passive layer, also known as the passive film, that protects the reinforcing steel in concrete. This disruption can lead to premature corrosion of the reinforcing steel in concrete. To minimize the risk...
At a time when the biodiversity on Earth is being rapidly lost, new technologies and methods in genomic analysis are fortunately allowing scientists to catalog and explore the diversity that remains more efficiently and precisely. The studies in this dissertation investigate genomic diversity within the milkweed genus, Asclepias, at multiple...
Phytophthora ramorum is a plant pathogen that was accidentally introduced to the United States. This invasive microorganism has killed over a million trees in California and Oregon, and continues to spread to new areas. Diseased areas have been nationally quarantined to prevent further spread and more than ninety countries include...
