Extracts of writings of great scientists and philosophers were used as handouts to supplement text and lectures on environmental science for nonscience majors requiring a laboratory course. An assessment form was developed to judge the impact of this process on students. Results of the first semester are described with plans for future implementation. A list of handouts is appended. 相似文献

当代国际科学学主流学术群体及其代表人物 总被引:8,自引:0,他引:8
运用信息可视化技术等新兴科学计量学方法,对1995年至2004年国际科学学领域论文高被引频次前50名作者进行分析,绘制出科学学主流学术群体及其代表人物的知识图谱。该图谱形象地显示出这些高影响力作者在当代国际科学学主流领域,形成了科技管理与政策、情报学与信息检索、科学知识图谱与信息可视化、网络计量学、科学社会学与科学知识社会学、科学计量学理论与科研评价等前沿分支学科的6个学术群体。成为这些前沿学科与主流群体的代表人物。他们为开创或发展当代科学学主流分支学科做出了突出贡献,产生了巨大影响,值得我国科学学界密切关注。 相似文献

自然科学家的实践的主体性思想绵延不绝,而且是比较深刻的。其基本特征是:实践的主体性需要充分地发挥;实践的主体性需要正当合理地发挥;实践主体性具有复杂性;实践主体性具有艰难性;实践的主体性离不开客观性。自然科学家的实践的主体性思想在实践的广度、深度、动态性和复杂性程度等等方面,丰富、深化了马克思主义哲学关于实践的主体性的观点的内容。研究自然科学家的实践的主体性思想,不仅是辩证唯物主义理论建设的需要,而且也是人类数千年来必然提出的课题。 相似文献

Science education researchers recently turned their attention to exploring views about nature of science (NOS). A large body of research indicates that both students and teachers have many naïve views about the NOS. Unfortunately, less attention has been directed at the issue of exploring the views of the scientists. Also, the little research in the literature generally took into consideration NOS views of only natural scientists. This study primarily proposes to explore the views of scientists in both the natural and social sciences regarding the seven target aspects of NOS. The second aim of the study is to find out the similarities and dissimilarities between the views of scientists who majored in social sciences and those who majored in natural sciences in terms of the target aspects of NOS. The sample was 69 scientists representing 5 scientific disciplines from natural and social sciences. Interviews were employed for obtaining data. The data were analyzed by means of cognitive maps. This study revealed that the scientists in the sample have neither completely informed views nor completely naïve views according to contemporary scientific understanding. Their views were a blend of the two in terms of almost all the target aspects of NOS. The views of the scientists in natural science and in social science were not substantially different. The scientists from both groups generally had similar viewpoints. This situation suggested that the scientists' views about NOS are not related to their scientific disciplines. 相似文献

Benefiting colleagues but not the city: Localized effects from the relocation of superstar inventors
Paolo Zacchia 《Research Policy》2018,47(5):992-1005
In this paper I examine episodes in which superstar inventors relocate to a new city. In particular, in order to assess whether the beneficial effects of physical proximity to a superstar have a restricted network dimension or a wider spatial breadth (spillovers), I estimate changes in patterns of patenting activity following these events for two different groups of inventors: the superstar's close collaborators, and all the other inventors in a given urban area, for both the locality where the superstar moves to and for the one that is left behind. In the case of collaborators, I restrict the attention to patents realized independently from the superstar. The results from the event study register a large and persistent positive effect on the collaborators in the city of destination, as well as a simultaneous negative trend affecting those still residing in the previous location. In the long run, these effects translate into an increased difference between the two groups of about 0.16 patents per inventor. Conversely, no city-wide spillover effect can be attested, offering little support to place-based policies aimed at inducing a positive influx of top innovators in urban areas. 相似文献

在科技界,男女科学家在产出和地位方面的差异是显著存在的,而且随着年龄的增长,男女科学家发表成果的差别越来越大。对造成男女科学家地位和成就分化原因的研究一直成为研究的焦点。本文在2006-2007年的问卷调查基础上,从科技女性主观价值偏好的视角,对此问题进行了解读。研究发现:主观偏好具有重要的影响;同时,在职业发展的不同阶段,科技女性主观价值取向与男性相比呈现不同的变化趋势。该结果从一个新的角度对我国科技界性别分层现象进行了解释。 相似文献
