孙学军：对汤森路透ESCI的解析

今天收到杂志主编的来信，说是Medical Gas Research (MGR)被Emerging Sources Citation Index收录。查找资料看这个ESCI什么意思，根据Thomson Reuters公司的解释，这个新的指标和过去SCI一样是一个新的分析产品。我根据自己的理解分析一下这个新指标的认识。  

先看看Thomson Reuters公司的官方解释。

INTRODUCING THE EMERGING SOURCES CITATION INDEX

This year, Thomson Reuters is launching the Emerging Sources Citation Index (ESCI), which will extend the universe of publications in Web of Science to include high-quality, peer-reviewed publications of regional importance and in emerging scientific fields. ESCI will also make content important to funders, key opinion leaders, and evaluators visible in Web of Science Core Collection even if it has not yet demonstrated citation impact on an international audience.

Journals in ESCI have passed an initial editorial evaluation and can continue to be considered for inclusion in products such as SCIE, SSCI, and AHCI, which have rigorous evaluation processes and selection criteria. All ESCI journals will be indexed according to the same data standards, including cover-to-cover indexing, cited reference indexing, subject category assignment, and indexing all authors and addresses.

Rapidly changing research fields and the rise of interdisciplinary scholarship calls for libraries to provide coverage of relevant titles in evolving disciplines. ESCI provides Web of Science Core Collection users with expanded options to discover relevant scholarly content. Get real-time insight into a journal’s citation performance while the content is considered for inclusion in other Web of Science collections. Items in ESCI are searchable, discoverable, and citable so you can measure the contribution of an article in specific disciplines and identify potential collaborators for expanded research.

首先、新指标是有身份的，将来你对一个杂志的评价，如果这个杂志能被ESCI收录，是这个杂志档次和身份的象征。但是这种层次相对过去SCI来说低一个档次，说是低一档次是虽然被收录，但没有影响因子。但是杂志的水平也不一定真的低于过去被收录的杂志。因为一些新的杂志在开始阶段受各种因素制约，无法达到收录标准，收录本身会影响投稿质量和数量。真正决定一个杂志质量水平的因素是杂志的编委队伍和出版社的服务质量。

其次，可以理解成为进入经典的SCIE的入场券。从这次扩容的规模上看，扩展的规模并不大，只有20%的数量，那么根据过去数据库扩展的速度，这种规模的杂志几年就可以被收录消化。也就是说这些杂志将很快进入经典的数据库。

最后，这种改革将对过去影响因子产生重大影响。因为这种收录意味着，整个数据库的扩容。被这些没有影响因子杂志论文引用将对过去杂志的影响因子产生影响。从杂志数量规模上看，这种影响将大约为20%。也就是说明年开始，过去老的杂志影响因子会产生一次突然上升的情况。

如何应对这种局面，对那些水平已经足够高的学者，这一变化你可以不考虑。对那些尚处于发表SCI有一点难度的学者，这次扩容是一次重要机会。因为这意味着杂志数量增大，可以选择的余地增加了，虽然档次差一点，总比不算强的多多了。在这些没有影响因子的杂志，我们可以自己计算出影响因子，利用这些线索可以估计明年进入核心数据库的可能性。这就好比你购买股票，这属于新三板，机会多，不同的是风险并不大。

最后广告一下，《医学气体研究》自从2011年5月发行以来，取得了非常不错的成绩。



作为亚洲区副主编，我强烈建议大家积极投稿我们的《医学气体研究》。最适合专业为麻醉学、高压氧、一氧化碳、硫化氢、一氧化氮、氢气、潜水医学等领域，接受论文类型多样，而且还可以申请免收版面费(有期限)。也欢迎符合条件的学者积极申请作为审稿人。

Dear All,

Congratulations on Medical Gas Research (MGR) being indexed in Emerging Sources Citation Index, which is a new edition of the Web of Science that launched in November 2015. This means that any articles published in the journal will be indexed in the Web of Science at the time of publication.

Introducing the Emerging Sources Citation Index:

In 2015, Thomson Reuters is launching the Emerging Sources Citation Index, which will extend the universe of publications in Web of Science to include high-quality, peer-reviewed publications of regional importance and in emerging scientific fields. The journals index in ESCI will not be issued an impact factor. However, each journal in this new index will be evaluated every year and those qualified will be transferred to SCIE.

Since 2016, MGR will be published by MedKnow, one of the largest open access medical publishers in the world. Benefits to get published in the journal:

1. No open access publications fees for the launch period

2. Being part of a new exciting journal in rapidly emering field

3. Fast first decision

4. Rapid publication times

5. Freely accessible and download online

6. Indexed in Web of Science

7. Easily searchable on PubMed and Google Scholar

Really appreciate your continuous support to the journal. For more information, please check the journal web site, and submit online today.

Wish you a Merry Christmas and a prosperous New Year!
