Products as diverse as soda-pop, fashion and
automobiles are selling to the tunes of classic and current
pop and rock music. The combination of MTV (Music
Television), the latest audio-visual technology, and the
replacement of movie stars by rock stars as the idols of
contemporary youth (Beckett, 1985; Hartman, 1987),...
The Gothic cathedrals of France arose in a particular social and political environment, and the material culture, the structures themselves and their contents, bear witness to those realities even today. In addition, the cathedrals themselves were catalysts for cultural change. They encouraged urban growth in a country that had previously...
This work was performed on Trillium albidum Freeman (Liliaceae), to
clarify the pattern of morphological variation between the small-flowered
populations at the northern limit of its range ( T. parviflorum Soukup) and the
larger-flowered populations from southern Oregon and northern California. It was
hypothesized that only a single species of...
Pea seed-borne mosaic potyvirus pathotype 1 (PSbMV-P1) has the ability to infect most genotypes of Pisum sativum. The exception are those genotypes that are homozygous recessive for the sbm-1 gene. The life cycle of PSbMV pathotype 4 (PSbMV-P4) is unaffected by the sbm-1/sbm-1 genotype. Infectious clones of Pl-P4 recombinants were...
Biodiversity studies allow for a more holistic approach to the conservation of
species. Using one measure ofbiodiversity, that ofspecies richness, this study
investigates the correlations between bird species richness and a set ofvariables. These
variables represent climate, productivity/available energy, habitat heterogeneity,
disturbance, and topography. Another aspect ofthis study is to...
In the early part of his philosophical career, Paul Ricoeur worked out a general theory of symbols which he illustrated with the symbols of evil. He subsequently explained this theory in several essays (his final major statement on symbols can be found in Interpretation Theory: Discourse and the Surplus of...
Heavy mineral compositions of sands from Oregon beaches,
rivers and sea cliffs have been determined in order to examine the
causes of marked along-coast variations in the beach-sand
mineralogy. The study area extends southward from the Columbia
River to the Coquille River in southern Oregon. The heavy-mineral
compositions were determined...
Habitat availability and use by an urban population of opossums
were studied with radio telemetry in Corvallis, Oregon in 1981 and
1982. For non-den observations, residential neighborhood types were
used about in the proportion available, agricultural/park/riverfront
neighborhood types were used in higher proportion than available, and
commercial/industrial neighborhood types were...
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...
Posting advisory speed signs at sharp horizontal curves to provide the driving public with a safe speed is a practice well established in the United States. The operational effectiveness of these signs has long been questioned in the current literature. The authors of this paper recently developed a function to...
