One of the most explosive social forces of modern-day society
is the phenomenon of urban intrusion into predominantly rural areas.
The recentness of this "explosion" has not yet allowed for a crystallization
of conceptual clearity as to just where this sector or
zone, which has come to be known as...
Data were gathered on the life history of the pile perch
(Rhacochilus vacca) from Yaquina Bay, Oregon, between April,
1966, and July, 1967. Pile perch feed on the bottom and consume
mostly molluscs, barnacles and decapod crustaceans. Food habits
varied among seasons and locations within the bay, whereas the
diet...
Time-resolved fluorescence spectroscopy was used to monitor the effects of
varying ionic strength on nucleosome core particle structure. Two main methods were
used in these studies. First, the fluorescence anisotropy decay of bound ethidium was
measured and was shown to reflect the rotational tumbling of the core particle through
solution,...
With increasing computing power, it is possible to process more complex fluid simulations. However, a gap between increasing
data size and our ability to visualize them still remains. Despite the great amount of progress that has been made in the field of
flow visualization over the last two decades, a...
The purpose of this study was to evaluate the student personnel
services rendered at a public two-year community college. The institution
chosen for the study was Lethbridge Community College, located
in Lethbridge, Alberta, Canada.
Six hundred and one people, representing seven population groups,
were randomly selected for participation in this...
The rhetorical significance of Mormonism stems from its history and its success—this success being measured by its consistent increase in membership. The total membership of the Mormon Church has grown from 6 members in 1830 to just over 14 million in just over 180 years. A consistently high rate of...
The education (particularly graduate education) of Americans
who were active in astronomical research between 1876 and 1941
is assessed for its effectiveness in preparing the astronomers for
careers in research. This period contains three dynamic changes:
the growth of American astronomy in becoming the world's leading
community of astronomers, the...
The hepatotoxicity of CB was studied in the Sprague-Dawley rat and rainbow trout. In rats, an ip dosage of 9.8 mmol/kg CB (~̲ LD10) produced evidence of liver toxicity over a 72 hr time course. Sulfobromophthalein (BSP) retention maximized 3-16 hr post treatment and normalized after 72 hr whereas plasma...
The purpose of this study was to determine if significant
relationships exist among terminal values, demographic variables and
health care preferences for information and behavioral involvement for
graduate students from the People's Republic of China and Taiwan.
The Rokeach Value Survey and the Krantz Health Opinion Survey
were used to...
The Late Spring Secondary Precipitation Maximum in the
Interior Pacific Northwest results from a complex system of climatic
controls. The Secondary Maximum is most strongly developed over the
high plateau of Oregon immediately in the lee of the Cascade
Mountains. Local topographic
organization exerts strong control
over the magnitude and...
A large number of river otter (Lontra canadensis) males were collected
from areas of high and low contaminant concentrations throughout western
Oregon and Washington during the fall and winter of 1994-99. Few significant
non-reproductive organ morphometric differences were found in the large series
of male otters collected, except for adrenal...

The study was devoted to identification and determination of
magnitude of change of prospective teachers with regard to the prospective
teachers' self perceived teaching ability. Teaching ability
was defined as a combination of teaching competencies identified by
other studies.
The general parameters of the study were to establish:
1. The...
The California adult education program has considerable freedom in the type of classes which may be offered, as long as certain requirements of the State Education Code are met. The study was conducted in five counties in the north San Francisco Bay area. Inquiry forms were used to obtain information...
This thesis describes investigations of archaeological materials recovered from Site ORBE2, an early-twentieth century historic site in Corvallis, OR. The archaeological materials were found only after construction workers had excavated trenches underneath the still-standing structure on the site in order to install a new foundation. Over 1500 artifacts were recovered...
Subduction zone earthquake and tsunami hazards affect tens of millions worldwide and the recurrence of these disasters can be evaluated with paleoseismic techniques, because earthquake cycles (and their supercycles) typically span many millennia. In these three chapters, I discuss a suite of analyses I use to evaluate the sedimentary record...

Predation by piscivorous marine fishes has been hypothesized to be a primary source of marine
mortality for Pacific Northwest juvenile salmon. During the springs and summers of 1998–2004, we collected predator and prey fishes (forage and juvenile salmonids) at the surface at night off the mouth of the Columbia River....
An understanding of the factors that influence surface erosion from roads is necessary to prevent and mitigate sediment production from forest roads. This study investigated the impacts of log truck traffic and road hydrology on sediment yield from ten forest road segments in the foothills of the Cascade Mountains of...
Pacific Salmon are anadromous fish that cross state and international boundaries in their oceanic migrations. Fish spawned in the rivers of one jurisdiction are vulnerable to harvest in other jurisdictions. The rocky history of attempts by the United States and Canada to cooperatively manage their respective salmon harvests suggests that...
Oakland is a quiet, peaceful little town on the Calapooya Creek surrounded by rolling hills and little valleys. This little booklet is written with the intention of preserving the history of our pioneers and contains a number of the names of the people who took doriation Land Claims and is...
