This publication takes this remark as a kick off point and is going directly to make clear a latest debate at the economic climate of data which is still relatively imprecise, applying the ways that various theoretical methods care for details. to grab the character and scope of the changes in our societies, a outcome of our new methods of dealing with, stocking and circulating details within the workings of the markets like organizations, this type of theoretical workout turns out necessary. The corporation of the e-book effects from this selection. The contributions accumulated in a single half take care of the position of knowledge within the functioning of the markets, these that includes in one other are extra drawn to the companies. To favour an enriching cross-reading of methods constructed within the sections already noted, we've preceded those with a bit amassing ways (which are extra transversal) constructing assorted theories of knowledge (according to views that are, respectively, systematic, statistical or strategic).

If H is the quantity of information transrnitted by both the substructures, two extreme cases are possible : H = H(yi)+H(y2) H = H(yi) = H(y2) In the first case, the two elements are independent that is to say that there is no constraint between them. In the second case the constraints are so important that the information corning from one element is sufficient to know all about the second. Such an analysis can be applied to an organization if each substructure is an individual or a group of individuals exchanging information.
Indeed if the information given by x is not sufficient to know y then there is an ambiguity which is measured by H(y/x). The "equivocation" is the opposite situation where the output message is known and where the uncertainty is conceming the input message. The equivocation is then measured by H(x/y). Before a message is transrnitted, it needs to be coded. Indeed it is the very problern Shannon tries to solve in the article he presents before the Macy group. He thinks that the redundancy is able to reduce both the quantity of information and the negative effect of noise.
