In recent papers on machine learning, the term 'operationalization' has been used to describe the purpose of the learning process. In particular, explanation-based learning systems are said to 'operationalize' the given target concept. Unfortunately, the exact meaning of this term has varied from one paper to another, and frequently the...
Summary of results. After implementing the plain ID3 algorithm, I experimented with
various modifi cations. Two improvements of the process of finding a legal phoneme/stress
could be made by using statistical information about the letter to phoneme/stress-mapping
in the training set.
Adding the CHI-SQUARE test to the ID3 algorithm was...
Based in part on previous work by this researcher, variables assumed to play a minor part in the process/ response system examined by the OSU Alsea Bay Hazard Study Team (1985-87)--river input and subsequent variations in hydrology--were more completely analyzed for their range of effects on the stability of Alsea...
Early and late seral tree species were compared for inter-and intraspecific competitive ability; within-population genetic variability; and allocation patterns of soluble sugars and starch seasonally and in response to shade and nitrogen fertilization. Species were Douglas-fir (early seral) and western hemlock (late
seral) from a low elevation habitat; and noble...
Black cottonwood (Populus trichocarpa Torr. & Gray) cuttings were collected from five Oregon provenances along a north-south gradient. Cuttings from each provenance were grown for 1 year at two locations, one on the Willamette Valley floor and the other on the Valley margin. Survival at both locations was poor. Stem...
The development of an effective infectious
hematopoietic necrosis virus (IHNV) vaccine depends on a
better understanding of the antigenic structure and
variation among isolates. Three objectives to elucidate
this were: (1) to generate a panel of antigenic
derivatives of the IHNV glycoprotein by monoclonal
antibody-mediated selection of neutralization-resistant
variant viruses,...
In this study, the level of drug. knowledge was
assessed among a sample of village practitioners in three
villages of Bangladesh by means of interviews using
questionnaires over a period of three months. The
objective was to find out how the type of training,
medical registration, source of background drug...
Linear phase variable filters that are obtained with a frequency transformation of the form cos(ω) = P(cos(W)) were analyzed, where P is a finite degree polynomial, ω is the prototype frequency and W is the transformed filter frequency. A new transformation of third order is proposed. The new variable filter...
A growing realization that wetlands are potentially
valuable resources has recently stimulated efforts towards
their protection. While a foundation for wetland management
exists, decision makers still lack adequate tools for addressing
issues of wetland preservation vs. development.
Wetland preservation values are often neglected in traditional
market analyses and in the...
The purpose of this research was to investigate the
effectiveness of using an early childhood language intervention
program with children who had been determined to be
language delayed at the ages of 3, 4 and 5 and to determine
how the early childhood langauge intervention program was
associated with changes...
The purpose of this study was to determine the validity of MMPI scores that were estimated from CPI data. This was later expanded to encompass whether generally low California Psychological Inventory (CPI) t-scores below 25 were predictors of elevated actual Minnesota Multiphasic Personality Inventory (MMPI) profiles. The sample consisted of...
In the mid 1970's, two critical forest planning directives were legislated by Congress. The Forest and Rangelands Renewable Resoures Planning Act (RPA), mandating that the U.S. Forest service undertake long-range planning initiatives, was passed in 1974. The National Forest Management Act of 1976 amended the RPA planning process. Together, these...
The migrations, distribution, and feeding of American shad, Alosa
sapidissima (Wilson), were studied from February 1980 through January
1981 in the Columbia River Estuary, an important rearing zone for
young-of-the-year shad. Sampling was performed with purse seine,
beach seine, and otter trawl.
Adult shad and large numbers of juveniles from...
Several studies have been conducted to examine the
utilization of non-protein nitrogen by the New Zealand
White rabbit.
Soybean meal (SBM) or urea added to a low protein (13%
CP) diet and a positive control diet were fed to does and
their offspring during a nine month experiment. Urea and...
The relative contribution of various inorganic and organic forms of nitrogen to the nitrogen requirements of picoplankton was examined with 15N tracers. Size fractionation was used to measure uptake by <1-μM size microorganisms, and inhibitors of protein synthesis were used to separate procaryotic from eucaryotic nitrogen uptake, Picoplankton utilized mainly...
A series of experiments were conducted to determine
the utilization of fibrous feeds by the rabbit. A review
of literature was performed to ascertain the results of
similar studies. The first two experiments involved
various levels of alfalfa substituted for corn or barley.
Results indicated that a 50 percent alfalfa...

of learning disabled adolescents in basic multiplication And
division facts. A multiple baseline design across subjects
with a follow-up was employed in an applied behavioral
setting. The subjects were two female and...

Petroleum oils have been used to suppress insect and mite pests for 100 years. Beginning in the 1880's, when kerosene was first used to control scale and aphids, to the present use of highly refined petroleum derivatives, these products have provided growers with a unique tool in their battle against...

Discipline is needed. There is no doubt about that. Society couldn’t exist if people acted without regard for others. Why, then, is there so much disagreement about this subject?
One reason is that many people don’t understand what discipline means. The word “discipline” comes from “disciple,” someone who follows the...

Power planning efforts in Oregon require accurate information
about hydroelectric potential. Potential uses for Geographic Information
Systems (GISs) are being investigated by three Oregon planning agencies.
This paper presents a method in which a 616 is used to help identify and
reduce uncertainty in previous hydroelectric inventories. Uncertainty with
respect...
Allocating use in wilderness by rationing is one way to
control crowding and resource deterioration problems. The wilderness
user's perception of wilderness management systems is vital to
effective management decisions when overuse problems arise. The
purpose of this study was to determine which direct rationing
systems users preferred. The five...
Recreation opportunity planning, including use of the recreation
opportunity spectrum (ROS), was developed to aid land managers in
inventorying, classifying, and managing outdoor recreation resources
within an overall planning framework. This planning concept, which
combines physical, managerial, and social setting characteristics
into an array of recreation opportunities ranging from primitive...
