摘要：This report is concerned with a rule learning system called the Distributed Learning System (DLS). Its objective is two-fold: First, as the main contribution, the DLS as a rule-learning technique is described and the resulting computational performance is presented, with definitive computational benefits clearly demonstrated to show the efficacy of using the DLS. Second, the important parameters of the DLS are identified to show the characteristics of the Group Problem Solving (GPS) strategy a...

摘要：We analyze a large-scale custom software effort, the Worm Community System (WCS), a collaborative system designed for a geographically dispersed community of geneticists. There were complex challenges in creating this infrastructural tool, ranging from simple lack of resources to complex organizational and intellectual communication failures and tradeoffs. Despite high user satisfaction with the system and interface, and extensive user needs assessment, feedback, and analysis, many users exper...

摘要：A theory is proposed for designing decision support systems (DSS) so that the confidence a decision maker has in a decision made using the aid equals the quality of that decision. The DSS design theory for user calibration prescribes properties of a DSS needed for users to achieve perfect calibration. Relevant calibration, decision making, and DSS literatures are synthesized; and related behavioral theories are borrowed to identify the properties of expressiveness, visibility, and inquirabilit...

摘要：After building and validating a decision support model, the decision maker frequently solves (often many times) different instances of the model. That is, by changing various input parameters and rerunning different model instances, the decision maker develops insight(s) into the workings and tradeoffs of the complex system represented by the model. The purpose of this paper is to explore inductive model analysis as a means of enhancing the decision maker's capabilities to develop insight(s) i...

摘要：Top management support is a key recurrent factor critical for effective information systems (IS) implementation. However, the role of top management support may not be as critical as external IS expertise, in the form of consultants and vendors, in small business IS implementation due to the unique characteristics of small businesses. This paper describes an empirical study of the relative importance of top management support and external IS expertise on IS effectiveness in 114 small businesse...

摘要：Reasons for the mixed reactions to todays electronic off-exchange trading systems are examined, and regulatory implications are explored. Information technology (IT) could provide more automated markets, which have lower costs. Yet for an electronic trading system to form a liquid and widely used market, a sufficient number of traders would need to make a transition away from established trading venues and to this alternative way of trading. This transition may not actually occur for a variety...

摘要：The structure and dimensionality of the user information satisfaction (UIS) construct is an important theoretical issue that has received considerable attention. Building upon the work of Bailey and Pearson (1983), Ives et al. (1983) conduct an exploratory factor analysis and recommend a 13-item instrument (two indicators per item) for measuring user information satisfaction. Ives et al. also contend that UIS is comprised of three component measures (information product, EDP staff and services...
