This study was designed to determine and compare the academic
experiences encountered by both American and foreign students in
master's and doctoral programs at Oregon State University in Winter
term, 1982. The findings of this study are meant to contribute to
the area of international education, by defining and describing...
The toxicity of chlorobenzene (CB) was investigated in rainbow
trout following acute ip administration (1. 0 ml/kg, 1:1 in corn oil)
and chronic exposure (2. 1 ppm and 2. 9 ppm) via the water in a continuously
flowing system for 15 and 30 days.
In the acute study, overt toxicity...
The main objective of this study was to estimate the demand for and net economic benefits from Oregon salmon sport fishing. The travel cost method was used as the primary technique for demand analysis. Several empirical estimates of consumer surplus per trip and per fish were obtained from different estimation...
This paper describes methods that can be used to
evaluate stand and tree growth response to a single
application of fertilization and/or thinning with data
collected from multiple installations. Two kinds of
methods were proposed: (1) structure analysis which
applies covariance analysis in a blocked design with and
without sampling...
Numbers of wild Canada geese (Branta canadensis) have increased dramatically during the past 30 years in the lower Columbia and Willamette Valley systems. The damage they cause by grazing and trampling plants can be substantial.
The objectives of this research were to:
1) Develop methods that provide reliable estimates of...
This study compared wives defined as underemployed by educational
mismatch with not underemployed wives on four major predictor variables--
relative market work advantage; degree of competition in the
female labor market; time demands from family members; and assistance
with childcare and other housework. The data were from NE 113, An...
This research was motivated by the use of multi-track feeders in the printed
circuit board (PCB) assembly. In a low volume, high mix production environment,
setup time is usually considered more important than processing time. Implementation
of multi-track feeders not only increases the capacity of the surface mount
machines but...
Measuring the source and magnitude of components of variation has important
applications in industrial, environmental and biological studies. This thesis considers
the problem of constructing confidence intervals for variance components in Gaussian
mixed linear models. A number of methods based on the usual ANOVA mean squares
have been proposed for...
This study involved the determination of the structural layer properties of
aggregate and asphalt surfaced pavements for use in the evaluation of pavement load
carrying capacity and the seasonal effects of moisture. This was achieved by the use
of Nondestructive Testing Methods (NDT) and backcalculation techniques. Pavement
surface deflection measurements...
There was a linear relationship of [alpha]-amylase activity
from 2 to 12 hours incubation in both freeze-dried and fresh
'd'Anjou' pear fruit tissue. Activity was greater, however,
in fresh as compared with freeze-dried tissues. [alpha]-Amylase
activity from both types of samples was not detected until
60 minutes incubation. After 90...
The golf swing involves a complex sequence of body movements which adjust according to the demands of a given shot. The purpose of this study was to determine common characteristics and essential elements of the golf swing under various conditions. The swing patterns of thirteen elite professional golfers were analyzed...
This dissertation describes the development of a mechanistic
overlay design procedure. The mechanistic analysis represents a new
trend in both new pavement and overlay design. The greatest advantage
of the mechanistic pavement analysis is that it considers the
fundamental characteristics of materials to be used, is capable of
considering changes...
It has been proposed that individuals develop models
of premarital relationships based on their preferred ways of
experiencing love with another person. This study attempted
to operationalize the concept of relationship models to
determine if individuals differ in how they expect their
feelings of love to develop over the course...
Studies were conducted in 1976 and 1977 on the effects of harvest
dates on maturity, yields and sugar content of four cultivars of
sweet corn. The cultivars were 'Golden Cross Bantam', 'Jubilee',
'Rapidpak' and 'Tendertreat'. Moisture content of kernels ranged from
80 to 67 per cent for the six harvest...
Two mathematical computer games, POE and EQUATIONS, were used to
test the effects of games as learning aids in a university entry-level
intermediate algebra course. Specifically, this study investigated
whether use of these games would significantly increase student achievement
in the course and improve student attitude toward mathematics.
EQUATIONS is...
In site index studies, the hypothesis that height
growth of most conifers is independent of stand density
is commonly accepted. However, some studies have shown
height growth to be influenced by density particularly
on medium to poor sites.
In this study two locations representing a high
quality site (Hoskins area,...
The purpose of this study was to provide the USDA-Forest Service,
Bureau of Land Management (BLM), and other agencies or industries
that may deal with temporary and intermittent use roads with
the necessary background information for the identification, economic
evaluation, and selection of the alternate surfacing systems and to
determine...
