基于ISI Web of Science数据库,利用其提供的统计分析功能,用文献计量学方法,分别从牛结核病研究的年代、国家/地区、文献类型、研究方向、发文机构、作者、来源出版物等方面对检索出的1986-2015年30年间的牛结核病方面的文献进行统...基于ISI Web of Science数据库,利用其提供的统计分析功能,用文献计量学方法,分别从牛结核病研究的年代、国家/地区、文献类型、研究方向、发文机构、作者、来源出版物等方面对检索出的1986-2015年30年间的牛结核病方面的文献进行统计分析。结果表明,1986-2015年间共有相关文献3308篇,文献类型以期刊论文为主,论文产出量呈逐年上升趋势,其中,美国、英国、新西兰发文量最高,中国仅居18位。牛结核病研究方向主要集中在兽医学、免疫学、微生物学、传染病学、生态环境科学和农学等领域。这对中国对牛结核病的研究有一定参考作用。展开更多

To this end we introduce a new measure, the "percentage range" or A-index, which provides a qualitative evaluation of a researchers' productivity. The percentage range depends to a great extent on the number of single-author published papers and their citations. It is to be a new index to be considered along with the h-index. The combined factors have the advantage of making clearer the innovation of the individual authors. The resultant percentage range gives a reduced impact on its numerical value for authors who gain citations by adding their names on multi-author papers. It is shown that various dimensions of ethical integrity and originality are clarified by the new index. The important scenarios arising from this analysis are demonstrated with examples, The great differences between the new percentage range and old h-index come from the percentage range's emphasis on considering the whole work of an author, including the significance of the author's single-author papers as opposed to multiple-author contributions. This emphasis is demonstrated.展开更多
