Over the period in question, the average number of authors per paper grew from 3.2 to 4.4. At the same time, the number of papers divided by the number of authors who published in a given year (essentially, the average author’s overall paper-writing contribution) fell from 0.64 to 0.51. The boom in co-authorship more than compensated for the drop in individual productivity, so that the average researcher notched up a slightly higher number of papers for his curriculum vitae: 2.3 a year compared to 2.1 two decades earlier.
在此期间,每篇文章作者平均数由3.2涨到4.4。同时,在特定的某一年,由论文的数量除以出版论文作者的数量得出的结果(从本质上来说,也就是作者的总文章贡献数)从0.64降到0.51。共同执笔的方式被广泛使用,补足了微薄的个人生产率,以至于一般来说,研究员个人简历上描述的文章发表数稍微多一些:和早先二十年前的2.1相比,涨到了2.3。
One particular trend behind these numbers is the rise of “guest authorship”, in which a luminary, such as the director of a research centre, is tagged on as an author simply as a nod to his position or in the hope that this signals a study of high quality. That can lead to some researchers becoming improbably prolific. For example, between 2013 and 2015 the 100 most published authors in physics and astronomy from American research centres had an average of 311 papers each to their names. The corresponding figure for medicine, though lower, was still 180. Figures for British universities are more modest but similarly striking. The top century of physicists and astronomers averaged 280 papers each; the top century of doctors, 139 papers. Indeed, it is so easy to add a co-author that some have honoured their pets. Sir Andre Geim, who won the 2010 Nobel Prize in physics, listed H.A.M.S. ter Tisha as co-author of a paper he published in 2001 in Physica B, a peer-reviewed journal.
“荣誉作者”(也就是杰出人物,比如研究中心的主任被贴上作者的标签以肯定他的身份,希望这标志着高质量的研究)的数量呈增加趋势。这让一些研究员论文成果不可思议地多。例如,在2013年到2015年之间,美国研究中心的100个出版率最高的物理天文作者,平均每个作者就有311篇论文。医药方面的作者尽管少,却也有180个。英国大学的数据平稳,但同样引人注目。在物理、天文领域发展的巅峰时期,物理学家和天文学家平均每人280篇文章;在医学发展的巅峰时期,医生平均每人139篇文章。甚至,一些学者把自己的宠物列入共同作者的名单,这对于他们来说是增加共同作者数目的简单方法。安德烈•海姆爵士于2010年获得了诺贝尔物理学奖,他曾把他的仓鼠 H.A.M.S. ter Tisha列为他在2001年于《物理期刊B》这本同行审查日志上出版文章的共同作者。
