Once upon a time students of mathematics and students of science or engineering took the same courses in mathematical analysis beyond calculus. Now it is common to separate" advanced mathematics for science and engi- neering" from what might be called "advanced mathematical analysis for mathematicians." It seems to me both useful and timely to attempt a reconciliation. The separation between kinds of courses has unhealthy effects. Mathe- matics students reverse the historical development of analysis, learning the unifying abstractions first and the examples later (if ever). Science students...

For the fourth time now, experts in tourism from various countries come to attend the ENTER conference in order to inform themselves and others about the current devel opments in the usage of information and communication technologies. The ENTER conference is thought as a platform for the exchange of ideas, experi ences, opinions, and visions among scientists and practitioners. The visions presented at the last three ENTER conferences have triggered many requirements of important on-going and planned projects in the application of communication and information technologies in tourism. The...
