摘要:Becoming an expert in any knowledge domain takes time and a great deal of learning, both theoretical and experiential. The individual’s knowledge is often supplemented through knowledge exchanges with other experts. Such exchanges are facilitated by events such as conferences or meetings. For two years we have been investigating the high profile work of scientists who work in the accredited anti-doping laboratories that are located in various countries around the world. These scientists work to curb doping in sport by conducting urinary analyses which detect athletes’ use of performance enhancing substances. These international experts, in the field of anti-doping science, work in a complex socio-technical context comprising both scientific and general anti-doping practitioners such as the staff of anti-doping agencies, sporting federations, sports physicians, coaches, athletes and the media. In order to maintain the high level of expertise necessary for this work, anti-doping scientists continuously search for and integrate new knowledge into everyday laboratory practice. To facilitate this process anti-doping scientists have developed working relationships and networks with other scientists working in the area. A major enabler of this process is the annual Manfred Donike Workshop on Dope Analysis. This paper describes the contribution of this event to the work of these expert scientists from an Activity Theory perspective.
