The semantic differential technique was used to
quantify four interest groups' perceptions of twenty-six
Alaskan scenes. The scenes represented both panoramic views
and views of Mount McKinley from different sites in southcentral
Alaska. The perceptions were measured on six semantic
scales ("ugly-beautiful", "dislike-like", "unpleasantpleasant",
"unstimulating-stimulating", "level-mountainous",
and 'monotonous-varied"), and the...
This thesis situates a discussion of Thoreau's later natural history essays in the context of the author's other writings. Beginning with an examination of the writings of Thoreau's friend and mentor Ralph Waldo Emerson, this paper examines Thoreau's relation to and departure from Emerson's understanding of time, place, and pattern...
Combustion emissions produced from burning real transportation fuels have many environmental impacts. However, detailed chemistry across multiple phases, time scales, and thermodynamic conditions make predicting combustion emissions challenging. Detailed modeling of the gas phase alone is prohibitively expensive, due to the large size and stiffness of the kinetic models. The...
The central purposes of this study were to review the
historical sources of David Kolb's formulation of experiential
learning theory, and to determine the effect and
application of Kolb's theory and Learning Style Inventory
as reflected in the literature between 1971 and 1990.
It was found that Kolb based his...
A greenhouse bioassay was used to investigate effects of natural and manmade disturbances on native ectomycorrhizal populations of Douglas-fir and western hemlock on a steep southeast slope in the
west central Cascade Mountains. Total and mycorrhizal root tips were counted on seedlings grown in soils collected from (a) two 100+...
The federally threatened northern spotted owl (Strix occidentalis caurina) is the focus of intensive conservation efforts that have led to much forested land being reserved as habitat for the owl and associated wildlife species throughout the Pacific Northwest of the United States. Recently, however, a relatively new threat to spotted...
Diets and foraging strategies of Glaucous-winged Gulls were
studied in areas with and without sea otters in the western Aleutian
Islands, Alaska. Gulls foraged on invertebrates (e.g., sea urchins,
limpets, chitons, mussels, and others) in the rocky intertidal
community and on fish at sea; this study was conducted on gulls...
This work focuses on the generation and collection of four specific
radioxenon isotopes; xenon-131m, xenon-133m, xenon-133 and xenon-135. These
nuclides are created by fissioning a highly enriched uranium sample using a
thermal neutron source from a university research reactor. The three main aspects
of this work include:
(1) Conducting preliminary...
The regulation of ergosterol biosynthesis in yeast has been
studied. The system has been examined for the presence of an end-product inhibition. Both anaerobically and aerobically grown cells
have been examined for this effect. A feedback inhibition of sterol
synthesis has been shown, but it appears to be a secondary...
This thesis examines the scholarship in pedagogical theory and practice of David Bartholomae over the past thirty-five years, in particular examining the role that the rhetorical construct of imitation has played in its development. Through my research, I trace the evolution of Bartholomae’s pedagogical stances and practices, as these both...
