Historians and sociologists of science often identify the efflorescence of social stud ies of science with the work of postwar American intellectuals such as Robert K. Merton and Thomas S. Kuhn. They often also refer to the views of Michael Polanyi (1891-1976) on the roles of tacit knowledge, apprenticeship, social...
Accessions of common wheat (Triticum aestivum L. subsp. aestivum) from the USDA–ARS National Small Grains Collection (NSGC) are a resource for wheat scientists worldwide. The genetic diversity of the wheat core subset, representing approximately 10% of the collection’s 42,138 T. aestivum accessions, was examined using 390 diversity arrays technology (DArT)...
New sources of genetic diversity must be incorporated into plant breeding programs if they are to continue increasing grain
yield and quality, and tolerance to abiotic and biotic stresses. Germplasm collections provide a source of genetic and
phenotypic diversity, but characterization of these resources is required to increase their utility...

The accessions used in this study were comprised of 246 snap bean and 49 dry bean genotypes. Of these, 150 snap bean accessions came from the Common Bean Coordinated Agriculture Project Snap Bean Diversity panel, an assemblage of 59 Chinese snap bean genotypes obtained from a trip to China in...
The hepatotoxic alkaloids known to occur in tansy ragwort (Senecio jacobaea L.) are also present in honey produced from the nectar of this species. These alkaloids, which include senecionine, seneciphvlline, jacoline, jaconine, jacobine, and jacozine, are potentially carcinogenic, mutagenic and teratogenic and may pose health hazards to the human consumer.
Seeds from 30 species of grasses and forbs native to Pacific Northwest prairies were tested for physical and physiological dormancy. The physical dormancy was determined by mechanically and chemically scarifying seeds. Physiological dormancy was evaluated with cold stratification before germination. Experiments were analyzed individually with ANOVA analysis, and by seed...
This paper reports on a study of primary contextualization processes during science immersion
trips and the resultant student learning. Four High School Ecology classes (n=67) and teachers
participated. Through a pre/post assessment of science concept knowledge (Pathfinder Network
Modeling) and follow-up interviews with students, it was determined that (1) significant...
Some authors defending the "hereditarian" hypothesis with respect to differences in average IQ scores between populations have argued that the sorts of environmental variation hypothesized by some researchers rejecting the hereditarian position should leave discoverable statistical traces, namely changes in the overall variance of scores or in variance-covariance relating scores...
Paper describes the formation of a Center for Digital Scholarship and Services at Oregon State University Libraries with a focus on how the library accomplished digital library and scholarly communication services. The paper describes the goals of the library in this area and the organizational and staffing changes that were...
