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

This article is a tribute to the life work of Maurice Kogan. Very little of higher education's landscape in the United Kingdom has remained unchanged over the past four decades and this article sets out to analyze the way the perception of the role of universities in society has changed in the intervening period. This it does through three perspectives: continuity and change, continuity in change and continuity in the midst of change. Each yields very different visions of the university. Against this ‘inside’ view, the second part of the article examines current British higher education policy from an ‘outsider’ standpoint and very particularly the current strategies towards the European Higher Education and Research Areas. It concludes by arguing that Britain's higher education policy vis a vis Europe re‐states a dilemma which these Islands have had to tackle for the best part of the past 250 Years. This dilemma is whether to lay priority on higher education as a global instrument or to endorse a more limited, less ambitious agenda of ‘European’ integration. 相似文献
