Adopting roles: Generosity and Presumptuousness

Evaluating the Risk of Adopting RBAC Roles

We propose a framework to evaluate the risk incurred when managing users and permissions through RBAC. The risk analysis framework does not require roles to be defined, thus making it applicable before the role engineering phase. In particular, the proposed approach highlights users and permissions that markedly deviate from others, and that might consequently be prone to error when roles are o...

A new generation of development economists represented by Spolaori an...

Less is given when the giver is paid on stage rather than in private; men receive less than women; fewer men than women give non-zero amounts. The results suggest that it may be problematic to organize experimental data in terms of social distance...
