摘要：Expert systems (ES) were among the earliest branches of artificial intelligence (AI) to be commercialized. But how successful have they actually been? Many well-publicized applications have proven to be pure hype, numerous AI vendors have failed or been completely reorganized, major companies have reduced or eliminated their commitment to expert systems, and even Wall Street has become disillusioned-a predicted $4 billion market proving to be smaller by an order of magnitude. Yet, in spite of ...

摘要：This study evaluates the extent to which the added value to customers from a supplier's application of information technology (IT) is manifested through premium prices of a traded good. The study demonstrates that IT can add value to an otherwise undifferentiated good and shows how these benefits accrue to customers from the adoption of IT. Analyzing a case in which the traded good is a homogeneous commodity-commercial fueling-our study shows that the critical impacts of IT are convenience and...

摘要：To use information technology to improve learning processes, the pedagogical assumptions underlying the design of information technology for educational purposes must be understood. This paper reviews different models of learning, surfaces assumptions of electronic teaching technology, and relates those assumptions to the differing models of learning. Our analysis suggests that initial attempts to bring information technology to management education follow a classic story of automating rather ...

摘要：This paper presents a teaching model that has been used successfully in the MBA core course in information systems at several universities. The model is referred to as the ''information Technology interaction Model'' because it maintains that the consequences of information systems in organizations follow largely from the interaction of the technology with the organization and its environment. The model serves a number of pedagogical purposes: to integrate the various course components, to pro...

摘要：Despite the significant demographic changes in the work force projected by the year 2000 and beyond, little empirical research has been made on the obstacles faced by women in the field of computing. Since career advancement prospects are especially salient for IS employees, and IS workers are considered a distinct occupational group, it is important to understand the career advancement prospects of IS employees. This study examines the impact of gender on job performance evaluations, job perf...

摘要：The IS function now includes a significant service component. However, commonly used measures of IS effectiveness focus on the products, rather than the services, of the IS function. Thus, there is the danger that IS researchers will mismeasure IS effectiveness if they do not include in their assessment package a measure of IS service quality. SERVQUAL, an instrument developed by the marketing area, is offered as a possible measure of IS service quality. SERVQUAL measures service dimensions of...

摘要：This paper discusses the role of individuals' beliefs about their abilities to competently use computers (computer self-efficacy) in the determination of computer use. A survey of Canadian managers and professionals was conducted to develop and validate a measure of computer self-efficacy and to assess both its impacts and antecedents. Computer self-efficacy was found to exert a significant influence on individuals' expectations of the outcomes of using computers, their emotional reactions to ...

摘要：Providing explanations for recommended actions is deemed one of the most important capabilities of expert systems (ES). There is little empirical evidence, however, that explanation facilities indeed influence user confidence in, and acceptance of, ES-based decisions and recommendations. This paper investigates the impact of ES explanations on changes in user beliefs toward ES-generated conclusions. Grounded on a theoretical model of argument, three alternative types of ES explanations-trace, ...
