The relationship between user participation and information system (IS) success has drawn attention from researchers for some time. It is assumed that strong participation of future users in the design of IS would lead to successful outcomes in terms of more IS usage, greater user acceptance, and increased user satisfaction. However, in spite of this, much(More)
One of the difficult challenges facing management and researchers today is how to justify costly investments in information technology (IT). This paper presents an approach to investigating the effects of IT on technical efficiency in a firm's production process through a two-stage analytical study with a firm-level data set. In the first stage, a(More)
The contribution of information technology (IT) to organizational performance has been investigated extensively in recent IS research. A number of economic and financial measures have been employed by researchers to gauge the impact of IT Journal of the Association for Information Systems 2 on organizational performance. The results of previous research can(More)
For computer assisted surgical simulation to be effective, objects in the simulated environment should respond to the user's actions dynamically with correct visual information. This includes dragging and cutting that cause changes in geometry, topology and appearance. Geometric object representation can be manipulated intuitively in real-time but does not(More)
Economic analysis of the hardware characteristics of the personal computer segment of the microcomputer market indicates that the variables that most affect cost are the bundle of attributes offered by the micros. Interestingly, certain technological characteristics found to be important explanatory variables for cost in larger computers were not found to(More)
