Social competence has emerged in research on social development
as a construct unifying behavioral and motivational dimensions of social
development in the preschool child. It draws from theories of social
learning, cognitive development, and competence motivation. The
theoretical relevance and empirical utility of the construct indicate
the need for further...
The North American species of the shore fly genus Notiphila Fallen were taxonomically revised. Over 13,000 specimens were examined from throughout the Nearctic Region and information relating to the biology of many species occurring in the West was gathered from both field and laboratory studies.

A complex and sometimes serious problem facing modern day forest
managers is that of estimating and analyzing potential on-site impacts
which result from forest activities. A major type of adverse impact
is man-Initiated forest erosion. This consequence can be substantially
magnified when forest harvest and road activities are implemented in...

Long-term oceanographic and meteorological data were used to develop models that describe the observed variation in the recruitment of Pacific mackerel (Scomber japonicus) in the California
Current region. The models that were found to best describe recruitment included both density-dependent factors and environmental factors. Models incorporating only density-dependent factors
accounted...
In recent years almost all states have legislated educational
and licensing programs to protect the welfare and property of citizens
engaged in outdoor recreational pursuits. Such programs exist
for automobile, motorcycle, airplane, and snowmobile operators.
However, boating continues to be one of the major recreational outdoor
activities where operators of...
The results of an experimental and analytical study of deep
submerged multiple-port thermal discharges are presented. The
experimental results include the measured downstream thermal dilution,
width, and centerline trajectory of the buoyant thermal
plume from multiport jets. Independent parameters for which
measurements were obtained include port spacing, discharge Froude
Number,...
Facility location studies involve the selection of a preferred
course of action from an array of multiattributed alternatives. The
factors affecting this selection are defined in both quantifiable and
qualifiable terms. The former comprises primarily monetary or operational
data, and the latter consists of nonmonetary and environmental
parameters; where the...
The purpose of this study was to determine if male and female
Counselor-Trainees enrolled in master's degree programs in the
State of Oregon would emit significantly different responses to a
new and professionally developed video-based client simulation.
The sample consisted of ninety-two Counselor-Trainees
enrolled during the 1975-76 academic year in...
Tansy ragwort (Senecio jacobaea L. ) is a poisonous weed which
infests alfalfa fields in western Oregon. Studies were conducted to
evaluate the effectiveness of asulam (methyl sulfanilylcarbamate)for
control of tansy ragwort in alfalfa and to elucidate factors responsible
for its selectivity. In seven replicated field trials in 1973 and...
The purpose of this study was twofold: First, to establish a means
of assessing the degree of professional status accorded student personnel
workers by constructing an attitude questionnaire, for student
clientele, based upon statements derived from eight criteria for
evaluating professional status; Second, to determine and analyze the
attitudes measured...
Despite relatively mild weather, black bears (Ursus americanus)
in southwestern Washington entered dens and remained for an average
of 126 days. Bears entered their dens during a 5-week period which
began on 21 October. A significant difference (P < 0.05) was found
among the average dates of den entrance of...
Root rot caused by Armillariella mellea creates roughly circular
disease centers of infected dead and dying trees in the younggrowth
ponderosa pine forest under study. Research objectives concerning
chemical control of the disease were: 1) to test the
effectiveness of certain chemicals in protecting living pines adjacent
to disease centers...
Chromatin DNA sequences intimately associated with the "core"
of the basic, repeating chromatin subunit are shown to be relatively
resistant to digestion by micrococcal nuclease. Chromatin DNA
sequences lying between adjacent chromatin subunits, as well as
DNA sequences in regions of chromatin which are free of chromatin
subunits, are subject...
The circular dichroism spectra of amylose, the maltose
oligomers, cellobiose, and the cycloamyloses are measured in
aqueous solution to 1640 A. Two bands are found in this region. The
long wavelength band is assigned to the ether chromophores; the short
wavelength band is assigned to the hydroxyls and further ether...
This investigation was designed to determine whether a remediation
program concurrent to enrollment in the Calculus could be used
to reveal and remedy student deficiencies involving pre-calculus topics,
promoting a greater degree of success in the Calculus. The instructional
model for the program that was investigated consisted of pretesting
the...
Rapid copper depletion without clinical symptoms of copper deficiency
was found in cattle under natural Klamath basin conditions.
Copper metabolism was influenced by grass species fed to the animals.

Fish collected at...
Investigations of plasma production by a pulsed dye laser
microprobe were made. Comparisons between a Q- switched and a
pulsed dye laser system were made on the intensity of the continuum
produced by atmospheric breakdown. The dye laser system was
foundtominimize the production of the continuum which in turn
allowed...
