Avoiding optimistic completion times due to the characteristic Program Evaluation and Review Technique (PERT) assumptions is a problem that can grow exponentially in complexity with the number of activities. A recursive technique that solves the problem in a polynomial number of steps has been developed, assuming that all duration times follow beta distributions. It is important to notice that the only two 100% valid approaches to calculate the project completion time are simulation and the stochastic sum for each and every path in the network. Nevertheless, both require finding the shape parameters, and that is precisely the main contribution of this paper: a system of equations to calculate the shape parameters of each activity and the overall project.

Moving a\vay from the pursuit of all-encompassing meanings helps us to navigate the compiexity associated \vith various views in information science and, as the authors explain, '. . be relaxed about the varied approaches and methods 'Nhich may be applied to information problems.' Information sciences (in the plural), they go on to explain, are dispersed. As an information researcher positioned in a centre of creative practice and cultural economy (areas unlikely to be considered traditional domains of information science), I welcome this pragmatism. It is nonetheless helpful to discuss (as the authors go on to do) whether or not we can identify a 'core' of information science and to consider the 'big questions' of information science in all their multifaceted complexity.

It traces a number of paths taken, from an early simple direct notion of interaction through to communication between people through art systems and, more recently, interactive art for long-term engagement. The frameworks consist of an evolving set of concepts, over several dimensions, which are developing together with the practice of interactive art..
