This study examines motivational factors influencing one's intention to continue using WWW applications. Social cognitive theory is adapted and integrated with expectancy disconfirmation theory and empirical findings from prior studies about continued use of information systems. Research hypotheses derived from this model are empirically validated using the responses to a survey on WWW usage, collected from 235 users. Results suggest that users' continuance intention is determined by their satisfaction with prior use, internet selfefficacy, and outcome expectations. Outcome expectation, in turn, is influenced by their satisfaction with prior use and prior perceived confirmation. This study draws attention to the substantial differences between acceptance and continuance. Implications for practice and further research are considered.

AbstractPurpose -This study extends the viewpoint of ''fit as holistic configurations'' to explore how to use knowledge management (KM) processes and knowledge management system (KMS) capabilities appropriately according to the tasks characteristics subunits perform in an aerospace manufacturer. In this regard, the aim is to develop four theoretical ideal profiles of KM processes (socialization, externalization, combination, and internalization) and KMS capabilities (codification capability and network capability) for organizational subunits based on their task characteristics: focused, process-oriented tasks; focused, content-oriented tasks; broad, process-oriented tasks; and focused, content-oriented tasks.Design/methodology/approach -The empirical study was conducted at a knowledge intensive and engineering-oriented aerospace company. Twelve functional subunits performing a variety of tasks were selected as the samples. The study employed qualitative and quantitative methods to understand the subunits' task attributes. The authors collected data from 12 subunits, and a total of 212 valid questionnaires were analyzed. PLS-Graph was used to assess the relationships of the research model.Findings -The empirical support for the argument that the fit among KM processes, KMS capabilities and task characteristics can improve KM performance. Results reveal that fit significantly affects knowledge satisfaction, knowledge quality and creativity for subunits performing focused, process-oriented and broad, process-oriented tasks.Research limitations/implications -The findings reflect the fact that individuals within organizational subunits should use the four KM processes of appropriate levels to generate new knowledge to accomplish their tasks.Originality/value -The study uses a multidimensional and multi-item approach to test the effect of factors on KM performance, and is the first to identify ideal profiles of KM process and KMS capability for different organizational subunits.

The main motivation of this research is how the issue of volitional control might affect the application of the theory of planned behavior (TPB) to research decisions related to information ethics. Specifically, a TPBbased model provides the best fit to the sample collected for the present study. In this model, the contribution of both the attitude and perceived behavioral control to the intention is shown to fluctuate depending upon the degree of volitional control concerning the targeted behavior. As the behavior's degree of volitional control lessens, the weighted influence of perceived behavioral control increases and that of the attitude decreases. Thus we confirm that degree of volitional control concerning an ethical act indeed plays a central role in applying the theory of planned behavior to information ethics research.
