HARD PROBLEM(S) ADDRESSED

  • Policy-Governed Secure Collaboration - Norms provide a standard of correctness for collaborative behavior, with respect to which policies of the participants can be evaluated individually or in groups.
  • Resilient Architectures - The study of robustness and resilience of systems modeled in terms of norms would provide a basis for understanding resilient social architectures.

ACCOMPLISHMENT HIGHLIGHTS

  • We have developed a second version of a simulation approach focused on a simplified of academic computing. This simulation framework captures a variety of interactions among the parties involved in academic computing along with their norms as well as potential sanctioning mechanisms.
  • We have begun to formulate technical definitions of the key concepts of robustness and resilience with which to assess the goodness of normative systems. These definitions build on a branching-time representation that captures multiple alternative futures of a given system state.
  • We have formulated hypotheses wherein (1) the independent variables include the nature of the interactions among the parties; the extent of monitorability of norm violations (such as how long it takes for the sanctioner to discover violation of norms); and the nature of the sanctioning mechanisms employed (such as sanctioning directed toward groups or individuals, in case of norm violations) and (2) the dependent variables include the liveness, robustness, and resilience of the associated normative system.
