Foreword While Mobile Communications continues to be a very successful industry, the number of s- cessful mobile applications still seems to be limited. Certainly, mobile voice and email are attractive to more and more customers. However especially during the boom around the UMTS license auctions much more fancy mobile applications were discussed, sometimes seen implemented - but never really widely used. Often high costs, especially compared to the costs of the "fixed" Internet, were given as r- sons for this. But considering the prices businesses, and more and more private people, pay for mobile voice and email connectivity, other reasons must exist for the reluctance to use mobile applications. One reason seems to be that quite a few people are not convinced, that mobile access or receiving information on a mobile device adds value. More formally spe- ing, usefulness or a relative advantage are not perceived, especially when the ones receiving the information are busy decision makers, who have other things to do. Especially when c- fronted with the still existing weaknesses of mobile devices, e. g. their limited I/O-capabilities they may see mobile work as mobile stress with no sustainable use.

Riassunto
In recent years, mobile applications and technologies have become valuable for many companies and their customers. This ongoing trend has affected both businesses and everyday life.
Jan Muntermann presents an intraday event study that is conducted within the German capital market, and provides evidence that investors could exploit intraday stock price effects following critical market events. He then develops the concept for a corresponding mobile decision support system that assists investors in identifying those events. Based on the design science research paradigm, he uses this concept in the design of a novel mobile decision support system, which can provide ubiquitous information access to private investors.
For this work, Jan Muntermann has been awarded the CCI Dissertation Prize 2007 sponsored by the Chamber of Commerce and Industry, Frankfurt am Main. The prize awards outstanding theses that emphasize practical relevance.
