Objectives of the Study
The study attempted to accomplish the following:
1. Document the fundamental or conservative nature of
early American higher education, especially the nine
colonial colleges, and verify its seemingly irrepressible
progression toward liberalism.
2. Determine the nature of variables associated with the
process of liberalization.
3. Isolate...
Large carnivores face serious threats and are experiencing massive declines in their populations
and geographic ranges around the world. We highlight how these threats have affected the
conservation status and ecological functioning of the 31 largest mammalian carnivores on
Earth. Consistent with theory, empirical studies increasingly show that large carnivores...

A study to determine possible impacts of cattle and big game grazing on streamside erosional responses was initiated in 1975. The objectives of the study were to: (1) establish the study and collect base line measurements; (2) determine the impact of animal grazing on soil bulk density and erosional potential,...
A sinking fund payment must be made each year to
retire a bond issue. Instead of paying cash, the corporation
will typically surrender bonds that it has purchased
on the open market. The sinking fund problem is to
determine an optimal strategy in the form of a stopping
rule to...
Many methods in use today for the isolation, purification, and
identification of the staphylococcal enterotoxins involve lengthy
steps with significant loss of enterotoxin, are subject to interference
from contaminating sample components, and lack sufficient specificity.
Culture extracts of enterotoxin producing Staphylococcus
aureus strains (enterotoxins A-E), crude enterotoxin preparations
(enterotoxins A-E),...

American genus, Ironoquia. Results of this survey are
presented and discussed for Allocosmoecus, Amphicosmoecus
and Ecclisomvia.
Field studies were conducted...
The primary purpose of the study was to identify the demand
for processed salmon from the West Coast. The basic approach in
the demand analysis was to identify those variables that determine
the supply and demand for processed salmon. An econometric model
was established containing the supply and demand equations...
The television show South Park, created by Trey Parker and Matt Stone, is viewed by millions of people each week, regularly addresses a number of controversial issues and plays a major role in contemporary popular culture. Current academic research acknowledges Parker and Stone's willingness to attack the dominant views surrounding...
This paper is a continuation of William Zell's thesis, A Model of Non-Euclidean Geometry in Three Dimensions. The purpose of that thesis was to show that the axioms of non-Euclidèan geometry are consistent if Euclidean geometry an& hence arithrnetic is consistent. Mr. Zell. discussed the axioms of connection and order...
Few studies analyze the relationship between ecological knowledge and public preferences for natural resource management options. The Central Cascades Adaptive Management Area (CCAMA) and McKenzie watershed of western Oregon provides an opportunity to examine the relationship. This research project employs a mixed model approach to explore public knowledge of forest...
Pool morphology was surveyed in 19 stream sections within the central Oregon Coast Range. Pool locations, sizes, spacings, numbers, and factors affecting pool formation were determined for each stream section. All sections were underlain by sedimentary rocks, had drainage areas ranging from 1.3 to 17.3 km², and had average water...
This report presents CTD observations of temperature & salinity as a function of hydrostatic pressure in the Kuroshio Extension. The data was taken during the deployment of a ten element current meter array in the Kuroshio in July 1980. CTD lowerings were made from the surface to the ocean floor...

The 1995/96 reintroduction of gray wolves (Canis lupus) into Yellowstone National Park
after a 70 year absence has allowed for studies of tri-trophic cascades involving wolves, elk
(Cervus elaphus), and plant species such as aspen (Populus tremuloides), cottonwoods (Populus
spp.), and willows (Salix spp.). To investigate the status of this...

Trophic cascades in Yellowstone: The first 15 years after wolf reintroduction
William J. Ripple ⇑, Robert
Gray wolves (Canis lupus) were reintroduced into Yellowstone National Park in 1995-96, thus completing the park’s large predator guild. In the fall of 2010, approximately 15 years after wolf reintroduction, we sampled ten genera/species of berry-producing shrubs within 97 aspen (Populus tremuloides) stands in the park’s northern ungulate winter range....
There is a lack of scientific consensus about how top-down and bottom-up forces interact to structure terrestrial ecosystems. This is especially true for systems with large carnivore and herbivore species where the effects of predation versus food limitation on herbivores are controversial. Uncertainty exists whether top-down forces driven by large...

Aldo Leopold, perhaps best known for his revolutionary and poignant essays about nature, was also an eloquent advocate during the 1930s and 1940s
of the need to maintain wolves and other large carnivores in forest and range ecosystems.He indicated that their loss set the stage for ungulate irruptions
and ecosystem...
We investigated how large carnivores, herbivores, and plants may be linked to the maintenance of native species biodiversity through trophic
cascades. The extirpation of wolves (Canis lupus) from Yellowstone National Park in the mid-1920s and their reintroduction in 1995 provided the
opportunity to examine the cascading effects of carnivore–herbivore interactions...
A table containing data from random sampling plots in 87 randomly located aspen stands in northern Yellowstone, repeating measurements by Painter et al. (2014). Stands were relocated using GPS coordinates from 2012. Each stand contained one plot 2x30 m, extending from the live, dead or fallen tree nearest the GPS...
During April 1979 the Oregon Department of Fish and Wildlife participated in a survey of Pacific ocean perch (Sebastes alutus) in cooperation with the National Marine Fisheries Service and Washington Department of Fisheries. The survey occurred off the coasts of Oregon and Washington from Newport, Oregon to Cape Flattery. Planning...
Satellite imagery of chlorophyll a concentration (chl a) provides the only holistic perspective
of productivity in marine ecosystems worldwide, yet its utility for understanding and
predicting the distribution of upper trophic-level predators remains equivocal. We tested the
hypothesis that remotely sensed chl a measurements spanning a decade can predict marine...
During the summer of 1994, 1996, and 1997, we conducted hydrographic and plankton surveys of the upper 70 m in the nearshore, the continental shelf, and off shelf oceanic waters off Oregon, USA. Copepod densities and biomass were estimated along 4 transects from each cruise. The on shelf copepod biomass...
