知识管理视野下的隐性知识   总被引：33，自引：2，他引：33  

施琴芬  吴祖麒  赵康 《中国软科学》2003,(8):96-102

本文对知识管理的研究和实践进行了简要的描述，发现知识管理研究和实践中明显存在着重显性知识轻隐性知识的倾向。这与隐性知识在知识管理中所起的作用极不相称。本研究通过对知识的分类和对现有隐性知识概念的梳理，对隐性知识有了一个较全面的界定，并认为隐性知识管理的内容和任务主要包括隐性知识的识别、隐性知识的开发利用以及隐性知识的保有和创新这三个大的方面。  相似文献   

推进农村工业化与城镇化的协调互动发展     

申茂向  祝华军  田志宏 《中国科技论坛》2005,(6):3-8

农村工业化和城镇化,是解决“三农”问题的两个重大战略,二者又是互相影响、相互制约的。本文分析了推进农村工业化与城镇化的协调互动发展的必要性,并对当前未能有效实现二者协调发展的原因进行了探讨,最后从理论认识和政策制度等方面提出推进农村工业化与城镇化协调互动发展的对策建议。  相似文献   

An empirical study of query expansion and cluster-based retrieval in language modeling approach     

Seung-Hoon Na  In-Su Kang  Ji-Eun Roh  Jong-Hyeok Lee 《Information processing & management》2007

The term mismatch problem in information retrieval is a critical problem, and several techniques have been developed, such as query expansion, cluster-based retrieval and dimensionality reduction to resolve this issue. Of these techniques, this paper performs an empirical study on query expansion and cluster-based retrieval. We examine the effect of using parsimony in query expansion and the effect of clustering algorithms in cluster-based retrieval. In addition, query expansion and cluster-based retrieval are compared, and their combinations are evaluated in terms of retrieval performance by performing experimentations on seven test collections of NTCIR and TREC.  相似文献

Using Research Based Assessment Tools in Professional Development in Current Electricity     

Ji Shen  Patrick C. Gibbons  John F. Wiegers  Ann P. McMahon 《Journal of Science Teacher Education》2007,18(3):431-459

We present a practical way of adapting and using four research-based assessments for different purposes in an electricity and magnetism course for K-8 science teachers. The course is designed to accomplish conceptual change toward accepted scientific conceptions as well as introducing teachers to materials and activities appropriate for their classrooms. Our data support that using the research-based tests to identify alternative conceptions and discuss test results with teachers is a promising way to use the knowledge of alternative conceptions in professional development. We also identify some mismatches between the research of conceptual change and its use in programs of professional development.

Comparison of high order aberration after conventional and customized ablation in myopic LASIK in different eyes of the same patient   总被引：4，自引：0，他引：4  

Du CX  Shen Y  Wang Y 《Journal of Zhejiang University. Science. B》2007,8(3):177-180

Purpose: To verify whether there exists any difference in higher order aberrations after undergoing myopic LASIK (laser in situ keratomileusis) with conventional ablation and customized ablation in different eyes of the same patient. Methods: This was a prospective randomized study of 54 myopic eyes (27 patients) that underwent LASIK using the Nidek EC-5000 ex-cimer laser system (Nidek, Gamagori, Japan). Topography-guided customized aspheric treatment zone (CATz) was used in the first eye of the patient (study group) and the other eye of the same patient was operated on with conventional ablation (control group). Higher order aberrations [root-mean-square (RMS) in the 5-mm zone] of both groups were observed with the Nidek OPD-Scan aberrometer before and 3 months after LASIK. Preoperative mean refractive error was similar between two eyes of the same patient (t=?0.577, P>0.05). Results: Preoperatively, higher order aberrations (RMS in the 5-mm zone) in the CATz ablation and conventional groups were (0.3600±0.0341) μm and (0.2680±0.1421) μm, respectively. This difference was not statistically significant (t=1.292, P>0.05). Three months after LASIK, higher order aberrations (RMS in 5-mm zone) in the CATz ablation and conventional groups were (0.3627±0.1510) μm and (0.3991±0.1582) μm, respectively. No statistically significant difference was noted between pre- and postoperative higher order aberrations in the CATz group (t=?0.047, P>0.05). However, a statistically significant increase in higher order aberrations was observed after conventional ablation (t=?5.261, P<0.05). A statistically sig-nificant difference was noted in the increase of higher order aberrations after LASIK between groups (t=?2.050, P=0.045). Con-clusion: LASIK with conventional ablation and topography-guided CATz ablation resulted in the same BSCVA (best specta-cle-corrected visual acuity) 3 month after LASIK. Higher order aberrations were increased, but the increase of higher order ab-errations after customized ablation treatment was less than that after conventional ablation.  相似文献   

多道计数比值法探查低水平人工γ辐射的实验研究     

王丽婷  王百荣  申俊峰 《实验技术与管理》2011,28(3):55-58

根据环境本底与人工放射性的能量分布差异,在常规低水平γ放射性探测实验的基础上,发展出多道计数比值法,以更准确快速地实现低水平人工γ辐射探查报警。实验采用NaI(Tl)探测器、多道采集卡和Matlab软件,建立实验用的探测报警系统,在非屏蔽环境中探测本底和低水平人工γ辐射。结果表明,该法能较好地识别环境本底中混杂的低水平人工γ放射性,降低误警率与漏报率。  相似文献
