摘要：The process of information technology adoption and use is critical to deriving the benefits of information technology. Yet from a conceptual standpoint, few empirical studies have made a distinction between individuals' pre-adoption and post-adoption (continued use) beliefs and attitudes. This distinction is crucial in understanding and managing this process over time. The current study combines innovation diffusion and attitude theories in a theoretical framework to examine differences in pre...

摘要：A model, based on Bandura's Social Cognitive Theory, was developed to test the influence of computer self-efficacy, outcome expectations, affect, and anxiety on computer usage. The model was tested using longitudinal data gathered from 394 end users over a one-year interval. Significant relationships were found between computer self-efficacy, and outcome expectations, and between self-efficacy and affect and anxiety and use. Performance outcomes were found to influence affect and use, while af...

摘要：A key issue facing information systems researchers and practitioners has been the difficulty in creating favorable user reactions to new technologies. Insufficient or ineffective training has been identified as one of the key factors underlying this disappointing reality. Among the various enhancements to training being examined in research, the role of intrinsic motivation as a lever to create favorable user perceptions has not been sufficiently exploited. In this research, two studies were c...

摘要：The received wisdom on IT chargeback is that a chargeback system with certain key characteristics, such as usage-based charges, stable rates, understandable bills, and so forth, will help firms make effective decisions on IT investment and use. Eccles' model of transfer pricing provides a theoretical Framework fbr this claim, and it also explains why chargeback systems can raise issues of fairness or create conflict between IT and its clients, as the IT literature has pointed out. Applying Ecc...
