First, I find the conditions under which the producer prefers to set a plan for the price he or she charges, or instead prefers to set a plan for the quantity he or she sells. Second, I show that the a...

To determine whether ochratoxin is produced by species of Aspergillus other than A. ochraceus, 44 strains representative of the nine species composing the A. ochraceus group were grown on both pearled wheat and cracked corn in duplicate shaken flasks at 28 C for 5 days. Rice was a poor substrate for production of ochratoxin. Molded substrates were extracted with acetonitrile-water; partially pu...

This provides the rationale for knowledge management wherein organizational knowledge must be shared, combined, and reused in order to enable organizations to compete more effectively.

Abstrac-t.We have developed a model that reconciles information-sharing and producerscrounger models of group foraging. Our model includes producers, scroungers, and an opportunistic forager that can both produce and scrounge but with reduced efficiency. We show that these three strategies can coexist only in the unlikely case that the opportunist's loss in searching ability is exactly equal to...

When post-harvest marketing strategies are restricted by disallowing speculative purchases, sales out of storage becomes an irreversible decision and the dynamic marketing problem becomes analogous to the optimal exercise of a nancial option. The optimal marketing strategy is to hold at low prices and to sell at high prices with a cutoo price function marking the boundary between low and high p...
