The Lawrence Memorial Grassland Preserve, located in
Wasco County, Oregon, exhibits a wide variety of soil mounds and
patterned ground features. The size, shape, and distribution of
several elements of this peculiar landscape were analyzed with a
detailed map, field observations, and statistical procedures.
Common soil mound shapes are circular,...
Karl Jordan (1861-1959) was an extraordinarily productive entomologist who influenced the development of systematics, entomology, and naturalists' theoretical framework as well as their practice. He has been a figure in existing accounts of the naturalist tradition between 1890 and 1940 that have defended the relative contribution of naturalists to the...
Monitoring reproductive success, prey species composition, and colony size of marine birds has been proposed as a method of assessing changes in marine systems that are otherwise difficult to sample (Cairns 1987). I measured inter-annual and intra-seasonal variability in reproductive parameters, taxonomic composition of the diet, and adult body condition...
Paleozoic dolomites, limestones, and detrital clastic rocks
were mapped in the Bellevue Peak 15 minute quadrangle in the
southern Mahogany Hills, Nevada. Sedimentary rock units in this
area represent shallow-shelf eastern assemblage deposits.
Shallow-shelf carbonates characterized deposition from at
least Ordovician through Late Devonian time, when clastics derived
Controversy regarding moral development research has given rise to a proliferation of theories competing for acceptance. For all these researchers, the work of Lawrence Kohlberg is the pivot point for comparisons, contrasts, and discussions. Still, no theories to date adequately describe and document a theoretically complete conception of moral judgment...
The basic problem of this investigation was to determine if
peer counselors could be effective as group counselors for Educational
Opportunity Program (EOP), freshman students. This effectiveness
would be demonstrated by changes in self concept and
academic adjustment for those students who participated in the group
counseling process. This investigation...
Reform in science education has often emphasized task-based learning as an
instructional method to improve student understanding and retention of concepts, and to promote the development of reasoning and problem-solving. Yet studies assessing
student knowledge at the beginning and end of a task-based class show mixed results.
Students in task-based...
Extensive new trackline coverage of the Chile Trench between
23°S and 34°S, including more than 60 bathymetric and seismic reflection
profiles across the trench axis, allows a much more detailed
study of the tectonics and sedimentation of this feature than previously
possible. Sediment distribution along the axis shows a remarkable...
