Checking Risky Events Is Enough for Local Policies

An extension of the λ-calculus is proposed to study historybased access control. It allows for parametrized security policies with a possibly nested, local scope. To govern the rich interplay between local policies, we propose a combination of static analysis and dynamic checking. A type and effect system extracts from programs a correct approximation to the histories obtainable at run-time. A ...

Risky prey behavior evolves in risky habitats.

Longstanding theory in behavioral ecology predicts that prey should evolve decreased foraging rates under high predation threat. However, an alternative perspective suggests that growth into a size refuge from gape-limited predation and the future benefits of large size can outweigh the initial survival costs of intense foraging. Here, I evaluate the relative contributions of selection from a g...

Managers and designers of technological systems face a common difficulty; new projects or products are inherently risky, both technologically and financially, especially given the rate of change in the high technology, deregulated economy. Consequently, they need solid methods for valuing prospective investments, so that they can justify their development strategies. Their fundamental problem i...
