Culturally based stereotypes are a pervasive force behind quick
judgments about behavior, intent, and beliefs which allow individuals to interact
efficiently to meet their own goals. Gender stereotypes are present in marketing
media and servicescapes, where they define the behavior, needs, and wants of
shoppers. The literature on consumer behavior...
We took the back-propagation algorithms of Werbos for recurrent and feed-forward neural networks and implemented them on machines with graphics processing units (GPU). The parallelism of these units gave our implementations a 10 to 100 fold increase in speed. For nets with less than 20 neurons the machine performed faster...
The gastrula of the sea urchin Strongylocentrotus purpuratus
was dissociated into single cells. In culture these cells appeared
apolar, but reassembled into quasi-normal embryos composed of
structures with polarized cells. In this study emphasis was placed on
those morphological events coincident with the reestablishment of a
polar orientation within the...
Forest harvest can have significant impacts on forest ecosystems that may
influence the capacity of soils to sequester carbon (C). The microbial community
controls decomposition, which is a critical process in partitioning litter- and root-C
between CO₂ and storage in semi-permanent soil-C pools. The objectives of this study
The gills of an Oregon crayfish, Pacifastacus leniusculus Dana,
were examined with histological and histochemical techniques and
their fine structure was investigated by electron microscopy. Special
attention was given to the structural basis of active ion uptake.
The histology of these gills was the same as that of other crayfish...
The U.S Pacific Northwest contains a wide variety of ecosystems, all subject to relatively dry summers and wet winters. As has been shown with paleoclimatic and paleoecological data, the region is vulnerable to changes in climate. We assessed the sensitivities of vegetation distributions, carbon stocks, and fire regimes to 21st...
Heat flow analysis of the Costa Rica convergent margin is carried out for seven core sites drilled during Integrated Ocean Drilling Program (IODP) Expeditions 334 and 344 as part of the Costa Rica Seismogenesis Project (CRISP). These expeditions were designed to develop a better understanding of erosional subduction zones. Heat...
