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

我国优秀蹦床运动员网上非技术性位移的初步研究   总被引：4，自引：1，他引：3  

牛雪松  刘兴 《沈阳体育学院学报》2003,(3):89-91

采用文献资料、现场观察、专家访谈、数理统计等研究方法 ,对我国高水平蹦床运动员网上水平位移现象进行初步研究。认为位移过大是影响成套动作稳定性及动作质量的重要因素之一 ;位移过大与起跳技术和连接技术不合理有关 ,也与运动员原有项目技能的负迁移影响有关 ;网上位移表现为一定的方向性 ,向前空翻类动作的水平位移略小于向后空翻类动作的位移。  相似文献

说说电视批评     

李幸 《中国广播电视学刊》2006,(2):55-56

2005年国内最出名．影响力最大的电视批评家是崔永元。尽管这位批评家没有写过一个字,但因其自身的知名度以及《南方人物周刊》的挖掘,他的许多出语便惊人了起来．并演成一场媒介事件。崔永元批评电视事件对我们的第一启示是:社会知名人物对电视的批评．恐怕今后得列入研究视野．因为他们的话,有点儿一石激起千重浪之效。比如崔说“收视率是万恶之源”．尽管他事后解释说是转述别人之语,但其效果就远远大于别人。由此我希望媒介继续挖掘名人对电视的看法．也希望名人不要太计较媒介记录或删削之误．以鼓起我国电视批评之风。顺便为所有名人提供一个对付媒体的良方: 不要企图让媒体完整地发表你两面或全面的看法．接受采  相似文献
