数学文化在小学数学新教材中的实践研究——以西师版为例     

孟梦  杨慧娟  李长毅 《数学教育学报》2012,(2):61-63

数学教育本质上就是数学文化的教育.基础教育课程改革以来,各版本小学数学新教材已经将数学文化作为一个新的教学要求渗透于其中,这是《标准》的要求,也是教学的需求.国内已有多套教材在这方面做了有益的探索,以西师版小学数学教材为例说明:小学数学教材中数学文化的题材选取要体现多样化,数学文化的呈现形式可以图文并茂,数学文化有必要并且能够从低年级多维度渗透到小学数学教材中.  相似文献   

法条竞合“禁止向一般条款逃避”之提倡——兼与张明楷教授商榷     

白晓东 《华侨大学学报(哲学社会科学版)》2012,(3):73-80

在法条竞合的情况下,法律适用采用"重法优于轻法",类似民法上的"向一般条款逃避"。从民刑比较而言,刑法的形式理性更高,刑法适用更应禁止"向一般条款逃避";从法律解释看,格式合同尚且作出对提供文本一方不利的解释,刑法犹如国家与国民订立的格式合同,亦应作出对国民有利的解释;从罪刑法定原则看,犯罪构成要件明确性要求刑法适用禁止"向一般条款逃避",亦是明确性原则的题中应有之意;可见,禁止"向一般条款逃避"亦是刑法的适用铁则。为此,刑法立法上,普通法条应配置较轻的法定刑;司法上,应杜绝随意将普通法条扩大解释,严格普通法条的适用条件,即便例外适用"重法优于轻法",也应当以刑法的注意规定为限。  相似文献   

Bibliometric profile of top-cited single-author articles in the Science Citation Index Expanded     

《Journal of Informetrics》2014,8(4):951-962

In this study, we identified and analyzed characteristics of top-cited single-author articles published in the Science Citation Index Expanded from 1991 to 2010. A top-cited single-author article was defined as an article that had been cited at least 1000 times from the time of its publication to 2012. Results showed that 1760 top-cited single-author articles were published in 539 journals listed in 130 Web of Science categories between 1901 and 2010. The top productive journal was Science and the most productive category was multidisciplinary physics. Most of the articles were not published in high-impact journals. Harvard University led all other institutions in publishing top-cited single-author articles. Nobel Prize winners contributed 7.0% of articles. In total, 72 Nobel Prize winners published 124 single-author articles. Single-authored papers published in different periods exhibited different patterns of citation trends. However, top-cited articles consistently showed repetitive peaks regardless of the time period of publication. “Theory (or theories)” was the most frequently appeared title word of all time. Leading title words varied at different time periods, and only five title words, method(s), protein(s), structure(s), molecular, and quantum consistently remained in the top 20 in different time periods.  相似文献   

Are the authors of highly cited articles also the most productive ones?     

《Journal of Informetrics》2014,8(1):89-97

Ever more frequently, governments have decided to implement policy measures intended to foster and reward excellence in scientific research. This is in fact the intended purpose of national research assessment exercises. These are typically based on the analysis of the quality of the best research products; however, a different approach to analysis and intervention is based on the measure of productivity of the individual scientists, meaning the overall impact of their entire scientific production over the period under observation. This work analyzes the convergence of the two approaches, asking if and to what measure the most productive scientists achieve highly cited articles; or vice versa, what share of highly cited articles is achieved by scientists that are “non-top” for productivity. To do this we use bibliometric indicators, applied to the 2004–2008 publications authored by academics of Italian universities and indexed in the Web of Science.  相似文献

论茅坤对柳宗元文章的接受     

莫山洪 《钦州学院学报》2013,28(1):19-24

茅坤在柳宗元文章接受史上地位特殊,是柳宗元文章地位奠定的关键人物。茅坤与柳宗元有相似的经历,对柳宗元能做出较客观评价。茅坤在韩柳问题上,能客观地评价柳宗元文章的地位,韩柳并称,柳宗元在古文运动中虽是协作者,但其成就与韩愈一样,在山水游记上则有过之而无不及。茅坤认为柳宗元是自古以来山水游记文章做得最好的文人,永州和柳州的山水与柳宗元的遭遇相结合,形成了柳宗元的游记文章,“公与山川两相遭”。茅坤还指出,柳宗元的文章是“谷风凄雨四至”,有风骚之旨。茅坤真正发现了柳宗元文章的价值,真正认识到柳宗元山水游记文章的地位,这在柳宗元文章接受史上有着特殊的意义。  相似文献
