The Grand Challenges Discourse: Transforming Identity Work in Science and Science Policy     

David Kaldewey 《Minerva》2018,56(2):161-182

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

中长跑项目多课次训练模式   总被引：4，自引：0，他引：4  

毕红星 《山东体育科技》2003,25(4):3-4,9

对中长跑“多课次”训练的概念、必要性、生理学基础等进行较为详细的论述，并对“多课次”训练计划的安排及应注意的问题作了说明，旨在丰富中长跑训练的方法手段，保证训练的质量，尽快提高成绩。研究认为。中长跑采用“多课次”训练是可行的。也是必要的，是科学化运动训练的一大体现。建议：“多课次”训练时间的安排，应突破传统的条条框框。在全天24小时内合理安排。实践中逐步摸索出适合每位运动员最为科学的训练课次及运动负荷量。  相似文献

我国竞技体育后备人才培养问题的理论探讨   总被引：2，自引：1，他引：1

伴随着经济一体化进程,我国竞技体育后备人才的培养受投资主体单一及竞赛制度的制约,各省市之间各自为政、封闭的后备人才培养体系效益较低。应该以国家“奥运战略”为目标,加强各省市体育后备人才培养合作,以发挥比较优势并提升整体竞争优势,为国家培养更多的高水平竞技体育后备人才。  相似文献
