China's long and continuous cultural tradition offers scholars the special opportunity for cross-cultural studies in the long-term development of science. The Partner Group focuses on an exemplary case of such long-term development, the development of mechanical knowledge in China from antiquity to the early modern period. Research within the Partner Group is guided by a number of specific research questions, in particular the question of the interaction between practical and theoretical knowledge and the interaction between domestic and external knowledge traditions over a period of more than a millennium. In order to establish a cross-cultural perspective on the emergence and development of experiential science, the research is being coordinated with the current research project on the history of mechanical thinking at the Max Planck Institute for the History of Science. 相似文献

The paper discusses the orientation of knowledge management in enterprises, a problem often neglected by the theoretical circles in the study of knowledge management. It points out that enterprise knowledge management is not exactly equal to knowledge management in theory, the former is only a branch of the latter. However, they are equally and alternatively used in practical applications as enterprise knowledge management is developing most rapidly and has the greatest influence. Therefore, the orientation of enterprise knowledge management is obscure. 相似文献

国外知识管理标准及对我国的启示 总被引：2，自引：0，他引：2
美国、英国、澳大利亚等一些国家已经出台了知识管理标准。知识管理标准的出台对规范知识管理的理论研究和实践探索都具有积极的作用。我国也于2009年出台了首个国家标准,但与国外相比,还存在诸如领导体制、规则细化、宣传影响等方面的不足。从国外知识管理标准的制定中,吸收一些经验,将有利于促进我国今后知识管理标准的发展。Abstract： Some countries represented by the United States,Britain and Australia have issued the knowledge management standard.The introduction of knowledge management standard has a positive effect on the standardization of the theoretical study and practical exploration of knowledge management.China also introduced the first national standard in 2009.However,compared with the foreign countries,there are some deficiencies such as in the leadership system,rule refinement and propaganda.Absorbing some experiences from abroad will help promote the development of knowledge management standard in China in the future. 相似文献

The Partner Group on Colloid and Interface Science is based on the International Joint Laboratory, established in the former Beijing Institute of Photographic Chemistry, Chinese Academy of Sciences (CAS), and was incorporated into the Center for Molecular Science of the Institute of Chemistry, CAS in 1999. The Partner Group aims at research on molecular assembly of biomimetic membranes and the synthesis of nano-structured materials by way of training younger Chinese scientists and making use of the advanced facilities in Germany. Both sides cooperate closely in sectors in which they have a common interest to push forward the development of related sciences in China. The group leader, Li Junbai, has received many awards and has obtained much financial support inside China. On the German side, the Partner Group is hosting or participating in several research and development projects commissioned by the Max Planck Society and the Deutsche Forschungsgemeinschaft (DFG). The Partner Group has thus secured goo 相似文献
