CSCW systems provide computer support to facilitate cooperation between users. In this paper we propose an approach for the formal speciication of func-tionality requirements and conndentiality security requirements of a CSCW application. These requirements give rise to safety and conndentiality properties that a CSCW system, supporting the application, should uphold. The speciication technique...

We distinguish between credit ratings that are based on probabilities of default and ratings that are based on expected default losses. We show that subdividing a bond issue...
