去年独立打败nature和science的那篇文章, 今年继续蹂躏他们已有40人参与
去年的影响因子刚刚出来,有一名不见经传的杂志ACTA CRYSTALLOGRAPHICA SECTION A,从前年的2点多分,狂飙到去年的49点多分,到今年的54.333, 把以前不可一世的nature,science,cell,NEJM等牛杂志全部都甩在了后面,仅次于 CA-CANCER J CLIN,排名世界第二,这究竟是为什么呐?
原来,在这个杂志里,2007年发了一篇名为A short history of SHELX.的文章,就这篇貌似不起眼的文章,在两年里被疯狂引用了6000多次,令人吃惊(影响因子的计算是用是年文章被引用数除以这年的文章数),有这篇被引用6000次的文章做基础,当然杂志的影响因子会变高了。
虽然这个杂志因为这一篇文章地位而陡然增高,但并不说明这个杂志真的有多少份量,这也说明了IF用于评价研究质量的不足之处。当然这并不是说影响因子作为评价论文优劣的指标是不好的,任何评价标准都有其不全面的地方,IF的标准我认为还是可以说明问题的,这次出现这种情况,只能说明是这事是太 麦子拉稀了
文章内容不是我的专业的,看不出到底哪儿好,能让人引用这么多次,以下是从pubmed上复制的,懂行的人可以看看指教一下,好象是什么用于一个分析晶体结构的程序的,我也没细看:

A short history of SHELX.Sheldrick GM.

AbstractAn account is given of the development of the SHELX system of computer programs from SHELX-76 to the present day. In addition to identifying useful innovations that have come into general use through their implementation in SHELX, a critical analysis is presented of the less-successful features, missed opportunities and desirable improvements for future releases of the software. An attempt is made to understand how a program originally designed for photographic intensity data, punched cards and computers over 10000 times slower than an average modern personal computer has managed to survive for so long. SHELXL is the most widely used program for small-molecule refinement and SHELXS and SHELXD are often employed for structure solution despite the availability of objectively superior programs. SHELXL also finds a niche for the refinement of macromolecules against high-resolution or twinned data; SHELXPRO acts as an interface for macromolecular applications. SHELXC, SHELXD and SHELXE are proving useful for the experimental phasing of macromolecules, especially because they are fast and robust and so are often employed in pipelines for high-throughput phasing. This paper could serve as a general literature citation when one or more of the open-source SHELX programs (and the Bruker AXS version SHELXTL) are employed in the course of a crystal-structure determination. |
