This article analyzes the concept of “grand challenges” as part of a shift in how scientists and policymakers frame and communicate their respective agendas. The history of the grand challenges discourse helps to understand how identity work in science and science policy has been transformed in recent decades. Furthermore, the question is raised whether this discourse is only an indicator, or also a factor in this transformation. Building on conceptual history and historical semantics, the two parts of the article reconstruct two discursive shifts. First, the observation that in scientific communication references to “problems” are increasingly substituted by references to “challenges” indicates a broader cultural trend of how attitudes towards what is problematic have shifted in the last decades. Second, as the grand challenges discourse is rooted in the sphere of sports and competition, it introduces a specific new set of societal values and practices into the spheres of science and technology. The article concludes that this process can be characterized as the sportification of science, which contributes to self-mobilization and, ultimately, to self-optimization of the participating scientists, engineers, and policymakers. 相似文献

ABSTRACTThe Strathfieldsaye Estate collection at the University of Melbourne Archives is discussed in relation to recognising, protecting and reclaiming Koori (First Peoples of southeast Australia) heritage. The settler collection includes early 1900s photographs of Koori people within two distinct albums – a family album that includes a series of studio portraits of Koori adults and children, and an album depicting Koori families on Ramahyuck Aboriginal Mission Station. In the past, these albums have been defined by, and limited to, traditional archiving practices excluding Koori interpretation, authorship and social context. Restoring Koori ownership and authorship of intangible heritage plays a large part in consolidating ancestor photographs with Koori perspectives of identity and culture. 相似文献
