摘要：Letters to shareholders in 649 annual reports published between 1972 and 1987 were analyzed for CEOs' views about information technology. Significant differences were found across industries banking, publishing, petroleum, and retailing in the number of times information technology was mentioned, the types of applications discussed, and the content of the discussion. The results of the industry analysis were in keeping with expectations based on the relative information intensity oft he variou...

摘要：This paper develops a model of the growth of information systems expenditures in the United States. The model incorporates two major factors that influence the rate and pattern of spending growth-the diffusion of technological innovation and the effect of price on the demand for computing. Traditional studies have focused on the role of innovation while ignoring the effects of price on the growth process. We show that while information systems expenses initially grew following an S-curve, more...

摘要：As organizational environments become more turbulent and as managers spend more time in meetings in an effort to deal with that turbulence, using information technology to support meetings has become more important. This paper reports on an experiment that compared meetings supported by information technology to meetings with conventional manual support only. The experiment differs from most previous group decision support system (GDSS) experiments in that solutions to the task it used could b...

摘要：Information technology is playing an increasingly integral role in the competitive strategies of many organizations. As this trend continues, it is not surprising that there is growing emphasis on the ability of organizations to plan, design and implement critical information systems. A major strategy to improve the effectiveness of these processes is the use of computer-based planning and design aids. However, there is little empirical evidence that using this technology provides a significan...

摘要：Information security has not been a high priority for most managers. Many permit their installations to be either lightly protected or wholly unprotected, apparently willing to risk major losses from computer abuse. This study, based on the criminological theory of general deterrence, investigates whether a management decision to invest in IS security results in more effective control of computer abuse. Data gathered through a survey of 1,211 randomly selected organizations indicates that secu...

摘要：This article presents a scheme called Difference Table for maintaining database snapshots stored at sites remote from a central database which are refreshed only upon user request. Database snapshots are currently in widespread use where a subset of the central database is extracted and transmitted to a local workstation and utilized for decision support. The Difference Table method checks each update to a central database table against the definition of the snapshot. If the update is relevant...

摘要：The primary objective of this study was to identify the perceptual dimensions used by 158 managers and their professional staff at a single large manufacturing firm in differentiating fourteen distinct communication channels available in the firm. Six candidate criteria for differentiating these channels were examined (channel accessibility, information quality, immediate feedback, cue variety, personalization, and receiver accessibility) using multidimensional scaling. A secondary objective i...

摘要：Strategic advantage through information technology is a popular and an important theme, but the extent of research support is minimal, anecdotal, and sporadic. This paper reports the results of a quasi-experimental study on the impact of dedicated electronic integration [between a focal insurance carrier and its independent agents in the property and casualty (P&C) market] for the focal carrier. The results indicate that the agents that are electronically interfaced with the carrier report imp...

摘要：A theoretical framework is developed in which alternative mechanisms of allocating congestion-prone computer resources are studied and compared. Two-discrete and continuum-models of economies are presented to depict a small and a large economy respectively. Alternative allocation mechanisms are discussed in these two models: (1) the private bargaining approach, (2) allocations attainable through Nash equilibria and (3) the Clarke-Groves tax mechanism in the discrete economy model, and (4) Mend...

摘要：The Decision Support Systems (DSS) literature is in general agreement that use of DSS leads to individual and organizational change, but there is no consensus as to whether DSS and their designers serve as agents for directed or nondirected change. Researchers have proceeded from two different sets of premises, drawing different conclusions about the nature of DSS. This paper considers both views, examining how differences in designers' attitudes toward change agency ought to be manifest in th...
