Tree diameter, understory plant cover, seedling density, elevation, aspect, and slope steepness are recorded for 51 forest stands dominated by Tsuga mertensiana (Bong.) Carr. along the eastern portion of the central Oregon Cascades. Species dominance based on prominence values for
trees and percent cover for shrubs and herbs are correlated...
The properties of evaporated aluminum-oxide films were investigated. The characteristics of MOS devices
made with single-layer aluminum-oxide films and double-layer
films which were made by evaporating aluminum oxide
over thermally-grown silicon dioxide as gate insulation
have been investigated. Vacuum-evaporated aluminum oxide
has features which are suitable for fabricating MOS devices....
This report presents the findings of a sediment analysis
program formulated to determine the flushing potential
of various shaped small boat marina basins. Chemical tests
regarding volatile solids, Kjeldahl nitrogen, grease and
oil, and sulfides were performed with the results compared
to established sediment quality criteria. These results
were used...
Barth's theory of transactional analysis is applied to the
community of Tiller, Oregon and its reaction to a development proposal.
Community behavior patterns vis-a-vis the development proposal are
examined from a processual point of view to determine how these
patterns are generated.
The community's history and contemporary situation are described....
The extent of the competitive effect of wild oats on winter wheat
yield was estimated in field studies on three commercial wheat farms in
the Willamette Valley. The morphological development of the wild oat
plants was also documented.
Wild oats were removed from stands of wheat in six different treatments;...
This thesis is an ethnohistoric study of the water rights of the Yakima Confederated Tribes. The study considers the water rights issues of the Yakimas from the cultural viewpoint at the time of European contact to the present legal and political situation. It traces the many obstacles the Yakimas have...
The Willamette River Basin, Oregon, viewed in terms of a cultural-ecological system, has been subject to three phases of cultural development: hunting and gathering, agrarian, and industrial-urban. Each population base has employed a technology to exploit the environment to the extent that its patterns of culture would allow. This technology...
Kelso's theory of Biocultural Evolution states that as culture evolves, the variation between groups diminishes while the variation within groups increases. The theory is tested with stature, cephalic index and nasal index. Means and standard deviations for these traits are examined for 237 ethnic groups. The groups are organized according...
The antiquity of the Northwest Coast Indian pole is the subject
of a great deal of controversy. A few viewpoints referring to that
topic are given. The symbolic value of the Kwakiutl totem pole is
examined with respect to art, style and culture; more generally
"primitive" art is considered as...
Samarium-neodymium data for authigenic ferromanganese
sediments from the oceans indicate that the Atlantic, Pacific, and
Indian Oceans each have a distinct range in Nd isotopic composition,
all of which are far less than ¹⁴³Nd/¹⁴⁴Nd ratios of source rocks with
oceanic affinities. Direct measurements of the Nd isotopic composition
of seawater...
The formation of capitalistic market-relations in the Third World
(known also as the underdeveloped world) has been an ongoing process for
hundreds of years. The degree of such capitalistic formation has been
mainly a function of the quantitative and qualitative nature of the
contact between the industrialized metropolitan centers (basically...
Straight, radial, erosional channels and fan-like deposits of tephra develop around steep-sided cones and composite volcanoes, but are not characteristic features of shield volcanoes. The channels and deposits normally are formed by explosive volcanic density currents which originate as nuées adrentes or base surges. The physical processes of explosive volcanic...
Precocious male coho are of limited economic value and control of their numbers returning to the hatchery or the increased survival of full-sized adults would be beneficial. Factors influencing
early sexual maturation and attempts to suppress this maturation of males through the incorporation of a hormone in the diet, treatment...
The applicability of electromyographic biofeedback toward alleviating
test taking anxiety was examined along with the effects of
relaxation training on general anxiety, locus of control, test performance,
and muscle tension during a test. The Achievement Anxiety
Test (AAT) was administered to 271 freshman psychology students.
Students whose scores indicated high...
The Beat Generation was an American counter-culture movement in the 1950's. Comprised of nomadic writers, poets, actors, musicians, and artists, the Beat movement represented no systematic philosophy and its most distinguishing characteristic was its apolitical disengagement from society. The Beats offered no substantive alternatives to the existing social order, but...
The late Oligocene Yaquina Formation is exposed in an arcuate outcrop pattern which extends along the central Oregon Coast from
Siletz Bay on the north to Seal Rock on the south. Maximum inland extent of the Yaquina outcrop is :five miles. Maximum thickness of the Yaquina Formation is 2, 000...
California bighorn sheep (Ovis canadensis californiana) were studied on Hart Mountain, Oregon, during the summer and fall of 1976, and the spring of 1977. The population consisted of a minimum of 196 sheep in June, 1977. The high number of lambs observed and high lamb:ewe ratios throughout both years of...
This study examines a limited number of selected themes in
Judeo-Christian, or Western, religious thought and their implications
for man's use of land, with the objective of discovering the influence
of Western religion on attitudes toward nature and land.
Five themes are examined: dominion of man; stewardship; contempt
for, and...
This investigation was designed to assess the effects of a victim's
race and stereotypical characteristics on another subject's willingness
to administer punishment within the context of a teacher-learner paradigm.
In addition, this study sought to empirically test the validity of the
social-psychological theory that states that theories of social behavior...
