Much development of information technology has been about reducing the importance of distances and user location. Still, many important activities and events are of local nature, for instance serendipitous face-to-face communication. In order to support such communication, as well as other examples of local interaction, we have developed three prototypes(More)
This paper reports from a project, called NewsPilot, where we explore how context aware computing can be used to support mobile collaborators. An empirical study of journalists at a local radio station in Sweden has informed the design of a prototype system. The system is built using a personal digital assistant (PDA) fitted with a radio transceiver and(More)
Anti-glomerular basement membrane disease (anti-GBM) is usually characterized by rapidly progressive glomerulonephritis, and when autoantibody production has ceased, relapses are rare. Here, we report a 71-year-old women diagnosed at a stage of mild renal insufficiency. Over a period of 10 years, she experienced three mild relapses with return of anti-GBM(More)
The objective of this paper is to discuss how to enable the staff at an order-packaging department to cope with a drastically increasing scale of operation. In order to do this we introduce the term scalability and based on coordination theory we formulate a case specific method for designing for an increasing scale of operation. We argue that it is the(More)
