With increasing amounts and variety of and access to open data collected in our environment, the distance between those who understand the data observation processes and those who analyse the data increases. This enlarges the risk of carrying out operations that are not meaningful, such as summing temperature values or interpolating coal power plant emissions. To avoid the need for tables with permitted analysis procedure for every phenomenon, we attempt to categorize phenomena first.... mehr

The health care environment is changing. While paternalism was the dominating paradigm for ages, the focus is now shifting to the individual patient and on empowering patients' to take an active role in their own health care. The increasing patient-centeredness reflects also on the health care information systems landscape. We investigate arising challenges from various perspectives including development of patient-centered health IT services as well as evaluation of information provision in... mehr

Future electrical power systems will be composed of large collections of autonomous components. Sensors and actuators, aware of their environment, with the ability to communicate freely, will have to organize themselves in order to perform the actions and services that are required for a reliable and robust power supply. Monitoring and efficiently operating such a system is a challenging task for the underlying information and communication (ICT) infrastructure as well as the system’s “... mehr

IS research is struggling with irrelevance. There is a huge gap between the development of novel and innovative IT tools on the one hand, and rigorous scientific methods on the other hand. Conferences and journals are filled with empirical studies that are well-executed but lack practical relevance and often even provide rather limited theoretical knowledge. At the same time, researchers developing IT artifacts often face well-justified critique concerning the scientific rigor in developing... mehr
