根据Bickerton,D的语义轮模型理论和Huebner,T的名词短语分类理论,对中国学习者英语语料库中的非英语专业大学生(ST3和ST4)写作中的英语冠词使用情况进行了分析。研究发现:名词短语的三大特性(特指性、听话者知识、可数性)对英语冠词的选择和正确使用有显著的影响;零冠词和定冠词存在不同程度的过度使用。 相似文献

利用《中国引文数据库(CCD)》作为样本统计源,分别对相同时间段不同学科、同一学科不同时间段的期刊h指数与载文量(n)、篇均被引量(p)进行统计与曲线回归,曲线回归结果良好,通过对《中文社会科学引文索引(CSSCI)》统计数据回归,进一步证实曲线方程的存在,并根据回归结果分析统计时间段差别对曲线系数的影响及曲线变化的基本规律。 相似文献

The purpose of this review is to further our knowledge about what is meant by inclusion in research addressing the topic. While it is common to remark that inclusion is defined in different ways in research, few attempts have been made to map and analyse different types of definitions and whether there are patterns to be find in how the concept is used. The 30 most cited journal articles from a North American and a European research arena were selected for analysis. Each article was analysed in relation to genre, theoretical tradition and inclusion concept used. The review yielded several important results. To name a few, a divide was identified between position articles, with developed discussions about and analyses of the meaning of inclusion, and empirical articles, where inclusion signifies that children with disabilities are placed in the mainstream. In addition, writing within a critical theoretical tradition was much more common among positional papers. Further, both arenas are dominated by Anglo-Saxon researchers. It is argued that the conceptual confusion characterising the field impedes its development. 相似文献

关于敦煌写本斋文的几个问题 总被引:4,自引:0,他引:4
郝春文 《首都师范大学学报(社会科学版)》1996,(2)
唐五代宋初,在敦煌佛教徒举行的各种斋会上宣读的斋文,文体结构可分为五个部分:一、颂扬伟的功德法力,称“号头”;二、说明斋会事由,赞叹被追福、祈福者或斋主、施主的美德,称“叹德”;三、叙述设斋的缘由与目的,称“斋意”;四、描绘斋会的盛况,称“道场”;五、表达对佛的种种祈求,称“庄严”。斋文的合集,称“诸杂斋文”。愿文只是其中的一种,不能作为“诸杂斋文”的通称。“诸杂斋文”还包括一些在佛事活动中宣读的类似文书,其中有的文体结构与斋文不同。 相似文献

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

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

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
