The purpose of this study was to determine if adding a specialized
instructional section on death and dying to ongoing curriculum
would affect attitudes of student nurses toward death and dying.
Subjects were 30 first-year nursing students enrolled in the Associate
Degree Nursing Program at Linn-Benton Community College, Albany,
Oregon....
The purpose of this two phased study was to determine the challenges to
implementing food safety and hazard analysis and critical control point
(HACCP) in school foodservice and the adherence to food safety
procedures in 15 schools. In phase one, food safety and HACCP
procedures were studied utilizing a focus...
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 overarching premise of this dissertation is to understand how different college and university physical activity education policies affect college and university students. Fundamentally, some American colleges and universities require their students to complete a physical activity education requirement whereas others do not. Given the different policy arrangements of college...
Ecological resources available to freshwater fish shift spatially, temporally and across life stages. To better understand how spatial-temporal availability of resources influence fish, I examined the phenologies of hatching and emergence of Coho Salmon (Oncorhynchus kisutch) in streams with contrasting and strongly defined seasonal thermal variability. The study streams included...
My investigations of the natural products of marine algae have resulted in
the discovery of several new secondary metabolites. Bioassay-guided
fractionation led to the isolation of these new compounds and spectroscopic
analysis was utilized in their structural characterization.
Two new and potent antimitotic metabolites, curacins B and C, were
isolated...
Riparian forests provide a myriad of ecosystem functions for adjacent streams and rivers, and due to these linkages, changes in riparian forest conditions can have direct implications for stream ecosystems. Resource managers in the coast redwood forests (Sequoia sempervirens) of northern California (USA) are actively thinning second-growth stands to accelerate...
This dissertation is informally divided into three major sections. In the first section (Chapter 2) I use data from field mapping, isotopic geochronology, whole rock geochemistry and trace element concentrations in zircons to examine the petrology, geochemistry and ages of the Haquira East porphyry copper deposit of southern Peru. In...
