Based on Paulson＇s inductive approach, we give the protocol model that includes infinitely many signatories and contract texts signing simuhaneously. We consider composite attacks of the dishonest signatory and the external intruder, formalize cryptographic primitives and protocol arithmetic including attack model, show formal description of key distribution, and prove signature key secrecy theorems and fairness property theorems of the BW protocol using the interactive theorem prover Isabelle/HOL.展开更多

This non-linear connection is similar to the worldwide documented quadratic （inverted U） relation between ownership concentration and a finn＇s Tobin＇s Q. The relation becomes even statistically stronger, when measuring ownership concentration using a strategic power approach, in an attempt to identify the source of this puzzling connection.展开更多

This would eventually lead to the final solution. However, the problem solution scenario is not so simple. Naturally, consumers＇ behaviors are difficult to be predicted and they do not always necessarily follow the rational-mind purchasing criteria. When purchasing food, mostly they choose the product because of its taste, quality and price, and lastly maybe due to its environmental friendliness from one hand.
