We construct an identity-based encryption (IBE) scheme that is tightly secure in a very strong sense. Specifically, we consider a setting with many instances of the scheme and many encryptions per instance. In this setting, we reduce the security of our scheme to a variant of a simple assumption used for a similar purpose by Chen and Wee (Crypto 2013). The security loss of our reduction is O(k)...

Medical errors can be reduced or avoided by training in both factual knowledge and in optimal information processing. The latter is of special importance when task settings are complex, when information about a patient’s condition is ambiguous and uncertain, and when rapid changes can occur. Simulations can contribute to effective training in these areas of functioning without putting patients ...

Some studies of IT companies have used agile approaches in software development and the IT-enabled global innovation ecosystem,1–4 whereas others focus on IT’s effects on innovation.5,6 However, it’s hard to f...

The fact that a company’s learning ability may prevent strategic drift and the fact that many companies are undertaking BPR projects leads us to ask whether all these BPR activities promote organizational learning. Within this framework we studied the extent to which BPR promotes organizational learning by focusing on the project group and the steering committee. This paper is based partly on a...

Decision tasks often require the extraction of information from displays of quantitative data. This paper investigates how people extract information from any one of several common displays by analysing the match between display, decision task and data. We posit two kinds of activity: first, the formulation of an appropriate extraction strategy and second, the execution of that strategy. We the...

Strategic bidding in joint energy and spinning reserve markets is a challenging task from the viewpoint of generation companies (GenCos). In this paper, the interaction between energy and spinning reserve markets is modeled considering a joint probability density function for the prices of these markets. Considering pay-as-bid pricing mechanism, the bidding problem is formulated and solved as a...

Information systems (IS) offshoring has become a widespread practice and a strategic sourcing choice for many firms. While much has been written by researchers about the factors that lead to successful offshoring arrangements from the client's viewpoint, the vendor's perspective has been largely scarce. The vendor perspective is equally important as offshore IS vendors need to make important de...
