Pellegrin, Liliane, Gaudin, Charlotte, Bonnardel, Nathalie and Chaudet, Hervé (2010): Collaborative Activities During an Outbreak Early Warning Assisted by a Decision-Supported System (ASTER). In International Journal of Human-Computer Interaction, 26 (2) pp. 262-277.

“This article introduces the resolution of a medical complex, uncertain, and time-constraint situation: the outbreak early warning in military deployment, which is assisted by a decision-supported system, ASTER, an application developed for early epidemiological alerting for French army forces. A simulated alarm occurring in the Department of Epidemiology in the Institute of Tropical Medicine of the French Forces, managed by physicians belonging to this department, has been studied. One goal was to have a set of systematized observations on the human-system interactions in a constrained and critical situation implying a team of public health experts. The ASTER system and a first study of its usage by experts in a simulated situation are presented, and the first results obtained in the context of the insertion of a complex human-computerized system interaction in a naturalistic situation of decision making are discussed.”

Pellegrin, Liliane, Gaudin, Charlotte, Texier, Gaetan, Meynard, Jean-Baptiste and Chaudet, Hervé (2010): Near real-time outbreak surveillance system for early warning as a JCS. In: Proceedings of the 2010 Annual European Conference on Cognitive Ergonomics 2010. pp. 33-40.

“Motivation -- This presentation introduces a near-real time outbreak surveillance system, ASTER, which assists physicians in the resolution the management of the outbreak early warning in French military deployment. Research approach. Our approach is to show that ASTER could be described as a joint cognitive system between actors belonging to a specific socio-technical network, a surveillance network and an artificial decision-supported system. Findings/Design -- Two simulations of an outbreak management have been set up. Observations of epidemiologists (analysis network) were conducted during simulated scenarii involving natural and intentional outbreaks within French Forces deployed for the first scenario, in Djibouti, and for the second one, in Tchad. Originality/Value -- The results of these studies highlight the central role of the building of a shared problem representation. This representation appears mainly to result from cooperative activities during decision making processes which are strongly supported by the main system, ASTER, but also by a panel of other decision-support systems and non-computerized and more classical artefacts.”
