摘要：The dynamic environment of an organization makes management difficult. This is especially true in information systems (IS) departments. A new theoretical model, based on structured interviews with IS executives, proposes ways that some dimensions of the environment create problems for IS management. IS managers develop coping mechanisms to attenuate or prevent these problems. They use these coping mechanisms either to resolve the problems directly or to influence the environment to prevent the...

摘要：Recent advances in computer technology have been accompanied by significant changes in the roles of both users and developers. One well-known example is end-user development, which here provides a context for the application of role theory to IS issues. A framework is proposed for classifying IS roles in a way that can be used for role behavior analysis. The framework takes the form of a matrix, with activities relating to the construction and use of information systems on one axis, and activi...

摘要：The process of knowledge acquisition has long been regarded as the bottleneck in expert systems development. In this paper, a concept induction methodology for automated construction of knowledge-bases is presented and its use for knowledge acquisition is discussed. The applicability of such a tool to build expert systems is demonstrated using CONIS in some selected experiments. CONIS is a concept induction system that infers concept description from sample instances of the concept. We have al...

摘要：This paper examines an information system design problem faced by the seller of a search good who sells his product in a competitive market to well-informed consumers. The formulation results in a nonlinear optimization problem having a special structure which can be exploited in solving the first-order conditions. Closed-form solutions and comparative statics results are given in the case of a uniformly-distributed attribute, and we provide a numerical example in the case of a normally-distri...

摘要：Judging by the wealth of problems reported in the literature, information systems (IS) and general managers are not sure how to manage the introduction of new information technology. One step toward providing sound management guidelines is to improve understanding of the social forces which affect the introduction and diffusion process within organizations. This research takes a step toward that goal by examining the validity of innovation diffusion theory within the context of end-user comput...
