ABSTRACTThis paper explores the dynamics between social innovations and socio-spatial transformations using practice theory as linking pin. Social innovations, such as the case study of a meal sharing platform here presented, are considered as proposals. Using social practice theory as a theoretical lens enables us to explain how the principles of the proposal’s design are moderated and appropriated by its users. Consequently, familiar routinized practices expand, becoming more complex and hybrid. It is in the performance of the practice that this complexity is revealed. Specific focus is on the socio-spatial transformations that social innovations propose. This paper shows how tactics of appropriation can result in trespassing the boundaries between private and public, and between domestic and communitarian space. This way, we connect social innovations to DIY-urbanism, showing how citizens appropriate urban space. 相似文献

The National Institute for Occupational Safety and Health (NIOSH) Division of Surveillance, Hazard Evaluations and Field Studies (DSHEFS) conducts investigations of health hazards in the workplace under the NIOSH Health Hazard Evaluation (HHE) program. In September 1990, the International Association of Fire Fighters (IAFF) requested that NIOSH assess the health and safety practices used by fire personnel during a brush fire on September 6, 1990, in Sedgwick County, Kansas. A 25-year-old fire fighter died of heat stroke at the scene.The NIOSH site visit to Sedgwick County, Kansas included a tour of the fire scene, personal interviews with 25 fire fighters and support personnel, and a review of incident reports, incident command procedures and other documents. NIOSH investigators concluded that a preventable series of events preceded the fire fighter's death. Recommendations were made for incident command and safety procedures, as well as medical monitoring, rehabilitation of fire fighters at fire scenes, and rehydration schedules. 相似文献
