Laboratory experiments and simulated field conditions were
utilized to gain a better understanding of the ecology of the clouded
salamander.
Animals collected in western Oregon were utilized for studies
in habitat selection, where it was shown that there was a significant
pattern of selection of litter types (rock, bark, and...
Samples of benthic organisms off the coast of Oregon, taken
from depths varying from 50 to 2900 meters, have been analyzed in
terms of diversity at a given station, and similarity and ecological
distance to other stations. Estimates of epifauna abundance were
also made. In the analysis an important distinction...
The purpose of this study was to investigate the relationship
between specific mother-child interactions and selected aspects of
language development in "disadvantaged" children.
The subjects were 19 preschool children in a summer Head
Start program in Denver, Colorado. Their ages ranged from four
years-nine months to five years-seven months. Eighteen...
The purpose of this thesis is (1) to study two Oregon communities
and to report data related to their concepts of community
education and (2) from this data, to develop guidelines for the planning,
organization, and implementation of comprehensive community-wide
educational programs. In accomplishing these purposes, it is
hoped a...
Morphological changes which occur during tentacle formation
have been described in the colonial athecate hydroid Cordylophora
lacustris. These changes involve an outpocketing of mesoglea into
a finger-like extension of the hydranth. Gastrodermal cells line the
inside of this extension of mesoglea while ectodermal cells cover the
outside. Electron micrographs reveal...
The purposes of this study were: to collect information relative
to the content of the sex education information adolescents have received
from selected sources, to ascertain their appraisal of the
value of this information and to test hypotheses concerning communication
and dissemination of information on sexual topics between
adults and...
A study of the relative rates of benzylic hydrogen abstractions
from a series of meta and para substituted neopentylbenzenes by the
bromine radical and trichloromethyl radical at 70°C has been carried
out. Application of the Hammett equation yields p values of -0.75
for the bromine atom and -0.94 for the...
