Prior studies have shown that perturbation methods are effective in protecting such confidential data from snoopers. Perturbation methods have to provide legitimate users. with accurate (unbiased) information, and also provide adequate security against disclosure of confidential infor...

This paper examines whether and when state technical capabilities attract foreign investment in manufacturing from. 1987-1993. We find that on average state R&D intensity does not attract foreign direct investment. Most investing firms are in lower-tech industries and locate in low R&D intensity states, suggesting little interest in state technical capabilities. In contrast, we find that firms in research-inte...

摘要：For multiobjective optimization problems, it is meaningful to compute a set of solutions covering all possible trade-offs between the different objectives. The multiobjective knapsack problem is a generalization of the classical knapsack problem in which each item has several profit values. For this problem, efficient algorithms for computing a provably good approximation to the set of all nondominated feasible solutions, the Pareto frontier, are studied. For the multiobjective one-dimensional...

摘要：Groups of organizations are pervasive, although there is little systematic knowledge about how they affect their members. We examine one dimension of the operation of organization groups, the transfer of experience. Our Fore,argument is that organization groups may create benefits for their members, but problems-for those outside the group. Within the group they can facilitate the transfer of experience among their members by creating mechanisms for communication, incentives for helping, and b...
