ACS titles post impressive Impact Factors
- 20 Jun 2017

The peer-reviewed journals of the American Chemical Society (ACS) are once again the most-cited and/or most-impactful scientific journals across 14 scientific categories, including six core chemistry categories, according to the 2016 Journal Citation Reports (JCR), released on June 14, 2017, by Clarivate Analytics. The citation-based rankings underscore the visibility and value of the broad research published within the Society's preeminent portfolio of journals.

The 2016 JCR affirmed the continued high impact and scientific importance of the Society's flagship peer-reviewed journal — the Journal of the American Chemical Society (JACS) — as the forum for publishing timely research findings of broad scientific significance. JACS recorded its highest-ever Impact Factor at 13.858. It continues to be the most-cited journal in chemistry with over 500,000 total citations in 2016, up 2 percent from the prior year.

ACS Central Science, the Society's first fully open access journal and distinguished winner of an American Association of Publishers' PROSE Award earlier this year, achieved a notable inaugural Impact Factor of 7.939. Free to readers and authors alike, it has quickly established its standing as an important forum for discoveries that feature chemistry research of interest and importance to those engaged in interdisciplinary areas of scientific inquiry.

Chemical Reviews also achieved its highest-ever Impact Factor at 47.928 and again ranks No. 1 in the category of Multidisciplinary Chemistry, as well as No. 4 out of approximately 12,000 journals covered by the 2016 JCR. This underscores the journal's role as an essential resource across the sciences for comprehensive and critical reviews of important developments in diverse areas of chemistry.

Four ACS journals within the Society's materials science portfolio received their highest-ever impact ratings this year, reflecting the strength of ACS Publications in fields of basic and applied areas of materials science that interface with other scientific disciplines. ACS Nano achieved an Impact Factor of 13.942, Chemistry of Materials an Impact Factor of 9.466 and ACS Applied Materials & Interfaces an Impact Factor of 7.504. ACS Biomaterials Science and Engineering debuted with an inaugural Impact Factor of 3.234, reflecting the strength of ACS in the field of materials science that involves applications from a number of scientific disciplines.

Of the 49 ACS titles covered by the 2016 JCR, 86 percent rank within the top quartile of their respective topical categories. Among this cohort are a number of journals that achieved their highest-ever Impact Factors.

More than 60 percent of the Society's journals posted an Impact Factor of 4 or higher with a portfolio median of 4.849 in 2016, up from a median of 4.803 in 2015. In addition, ACS journals were cited more than 2.9 million times in 2016, representing an increase of over 6 percent from the prior citation total.

AACC announces rise in impact factor of its journal, Clinical Chemistry
- 19 Jun 2017

AACC, a global scientific and medical professional organisation dedicated to better health through laboratory medicine, has announced that the impact factor of its journal, Clinical Chemistry, has risen to 8.008 in the 2016 Thomson Reuters Journal Citation Reports. This impact factor places Clinical Chemistry in the top 2.6% of 12,062 ranked academic journals and speaks to the significant influence of the science it publishes on laboratory medicine and patient care.

Laboratory medicine professionals provide essential answers to clinicians so that patients get the care they need—from diagnosing the flu to identifying the therapies that cancer patients will respond to best. As the most trusted and authoritative journal in laboratory medicine, Clinical Chemistry strives to advance the field by showcasing vital research that holds the key to challenging patient health problems. Every year, Clinical Chemistry publishes 2,000 pages of peer-reviewed papers that drive clinical testing forward and are chosen based on the novelty of their findings as well as the high quality of the scientific evidence they present. These papers cover timely subjects ranging from designer drug and Zika testing to emerging technology, such as mass spectrometry, that is transforming the way medical tests are performed.

Clinical Chemistry's consistently high impact factors reflect the exact standards met by the research the journal publishes. A journal's impact factor—calculated by Thomson Reuters, a recognized authority for evaluating the usefulness of a journal—is determined using the number of citations received in that year by articles published in the journal during the two preceding years.

ACMG's journal Genetics in Medicine now in top 2.5% of all indexed journals
- 19 Jun 2017

The American College of Medical Genetics and Genomics (ACMG) has announced that the Thomson Reuters Impact Factor Journal Citation Reports has just increased the impact factor of the ACMG's peer-reviewed medical genetics and genomics journal, Genetics in Medicine (GIM) to 8.229 for 2016, up from 7.710 in 2015. Genetics in Medicine is published by Springer Nature.

GIM is currently ranked 10 of 166 titles in the Genetics & Heredity category and is the top-ranked of genetic journal that has a primarily clinical focus. The Impact Factor is an objective measure of the world's leading journals, based on articles' cited references and is oft considered a measure of a journal's overall successful performance and relevance to its field.

The journal, published since 1998, is supported by an expert Board of Editors representing all facets of genetic and genomic medicine, including such specialties as biochemical genetics, cytogenetics and pharmacogenetics.

Cochrane announces 2016 Impact Factor for Cochrane Database of Systematic Reviews
- 15 Jun 2017

Cochrane, a global independent network of researchers, professionals, patients, carers and people interested in health, has announced that the Impact Factor of Cochrane Database of Systematic Reviews (CDSR) is now 6.124. According to 2016 Journal Citation Report (JCR), released by Clarivate Analytics (formerly Thomson ISI), this is a slight increase on the 2015 impact factor, which was 6.103.

The CDSR impact factor is calculated by taking the total number of citations in a given year to all Cochrane Reviews published in the past 2 years, and dividing that number by the total number of Reviews published in the past 2 years. It is a useful metric for measuring the strength of a journal by how often its publications are cited in scholarly articles.

Some highlights of the CDSR 2016 Impact Factor include: the CDSR is ranked 14 of the 154 journals in the Medicine, General & Internal category; the CDSR received 57,740 cites in the 2016 Impact Factor period, compared with 47,899 for the 2015 Impact Factor calculation; the total number of times the CDSR was cited increased from 47,899 in 2015 to 57,740 in 2015 meaning the CDSR received the 5th highest number of citations in its category; and the 5-Year Impact Factor is 7.018.

The main Impact Factor report and the CRG reports will be delivered after the JCR is updated in September. This is because, as has happened in previous years, Clarivate was unable to accurately index Cochrane Reviews for this Impact Factor window; Wiley and Cochrane are following-up with Clarivate regarding the calculation of the 2016 impact factor.

San Francisco Declaration on Research Assessment calls for sweeping changes in scientific assessment
- 20 May 2013

Scientists, journal editors and publishers, scholarly societies, and research funders across many scientific disciplines have posted an international declaration calling on the world scientific community to eliminate the role of the journal impact factor (JIF) in evaluating research for funding, hiring, promotion, or institutional effectiveness. The San Francisco Declaration on Research Assessment, or DORA, was framed by a group of journal editors, publishers, and others convened by the American Society for Cell Biology (ASCB) in December 2012 in San Francisco, during the Society's Annual Meeting.

The San Francisco group agreed that the JIF, which ranks scholarly journals by the average number of citations their articles attract in a set period, has become an obsession in world science. Impact factors warp the way that research is conducted, reported, and funded. Over five months of discussion, the San Francisco declaration group moved from an 'insurrection,' in the words of one publisher, against the use of the prominent two-year JIF to a wider reconsideration of scientific assessment.

The DORA statement makes 18 recommendations for change in the scientific culture at all levels - individual scientists, publishers, institutions, funding agencies, and the bibliometric services themselves - to reduce the dominant role of the JIF in evaluating research and researchers and instead to focus on the content of primary research papers, regardless of publication venue.

The declaration is timed to coincide with editorials in scientific journals worldwide including an endorsement of DORA by Bruce Alberts, Editor-in-Chief of Science Magazine in the journal's May 17th issue. Other editors signing DORA represent Journal of Cell Biology (JCB), Traffic, Genetics, eLife, Journal of Cell Science, Aging Cell, Molecular Biology of the Cell (MBoC), BioArchitecture, The EMBO Journal, Journal of Cell Science, Journal of Surfactants & Detergents, Cell Structure & Functions (Japan), Lipids, Genes, Journal of the Electrochemical Society, and Development. A complete list of signatories to date is available at http://www.ascb.org/SFdeclaration.html.

The San Francisco declaration cites studies that outline known defects in the JIF, distortions that skew results within journals, that gloss over differences between fields, and that lump primary research articles in with much more easily cited review articles. Further, the JIF can be 'gamed' by editors and authors, while the data used to compute the JIF 'are neither transparent nor openly available to the public,' according to DORA.

Elsevier announces 2011 Journal Impact Factor highlights
- 18 Jul 2012

STM publisher Elsevier, Netherlands, has announced the highlights of its journal Impact Factor performance in 2011. According to the 2011 Journal Citation Reports (JCR) published by Thomson Reuters, Elsevier saw 58 percent of its journal Impact Factors increase from 2010 to 2011, compared to 54 percent for non-Elsevier journals.

Elsevier journals top the rankings in 57 subject categories. Nearly 40 percent of Elsevier’s 1,600 journals in the JCR are in the top 10 of their subject category, with 188 journals ranked in the top 3. Five Elsevier journals have seen a decade of continuous Impact Factor increases. These are: Journal of Ethnopharmacology; Journal of Materials Processing Technology; Carbon; Electrochemistry Communications; and Renewable Energy.

All journals in The Lancet family reached their highest Impact Factor yet. The Lancet rose from 33.633 to 38.278, remaining the second-highest ranked journal in the Medicine, General & Internal category. The Lancet Infectious Diseases and The Lancet Neurology retained their number one rankings in their respective categories, while The Lancet Oncology saw its Impact Factor soar from 14.470 to 17.764.

Cell, the flagship journal of Cell Press, an Elsevier imprint, saw its Impact Factor remain stable at 32.403 and continues to be the top primary research journal in the Cell Biology and Biochemistry & Molecular Biology subject categories. Among Cell Press’s more recent suite of journal launches, Cell Stem Cell (Impact Factor 25.421) had the highest percentage growth in citations in its field. More than 70 percent of the Trends review journals had an increased Impact Factor this year.

Of the 383 journals in the JCR that Elsevier publishes on behalf of societies, 64 percent saw increases in their Impact Factors. Nine of these are number one in their subject category, with four achieving that top position in 2011: PAIN (International Association for the Study of Pain); Annals of Emergency Medicine (American College of Emergency Physicians); Combustion and Flame, and the Journal of the American Academy of Child & Adolescent Psychiatry which now also ranks number one in the Pediatrics category.

The Impact Factor helps evaluate a journal’s impact compared to others in the same field by measuring the frequency with which recent articles in a journal have been cited in a particular year: the 2011 Impact Factor takes into account citations in 2011 to papers published in 2009 and 2010.

ACS journals lead impact factors across 27 subject categories in chemisty
- 29 Sep 2011

The American Chemical Society (ACS) has announced that its peer-reviewed scientific journals have been ranked as leaders in 27 subject categories in a recently released independent study. In this study, 60 percent of all journals published by ACS have an Impact Factor (a widely accepted metric of a journal’s impact in its field) of 4.0 or over — a greater proportion than any other publisher in the chemical or related sciences. Thomson Reuters reports that ACS Publications retains its leadership as the most cited sources in seven core chemistry publishing categories.

The standardised Impact Factors and ranking system of Thomson Reuter’s Journal Citation Reports are seen as the foundation of how scientists around the world determine where to publish and what sources of chemical research they use in their professional endeavours. ACS Publications journals achieving superlative results in 2010 include the Journal of the American Chemical Society, the most cited journal in Multidisciplinary Chemistry with a record 369,164 total citations and a rise in Impact Factor to 9.019, and Chemical Reviews, the highest impact journal in chemistry, with an Impact Factor of 33.033. All told, journals from ACS Publications rank number one in either Impact Factor and/or total citations in 14 ISI scientific categories.

Citation statistics — the number of times papers from a journal are cited by other scientists each year in their own research — are said to be important indicators of a journal’s value and vitality to active researchers. With over 1.4 million citations in the seven chemistry categories, ACS Publications journals are the most cited in chemistry. Thomson Reuters calculates that total citations of American Chemical Society journals increased by 8 percent in 2010, posting 1.8 million total citations on the year.

The high ranking of ACS Publications journals is seen as a testament to the independent editors of ACS journals, who are all noted and practicing scientists, and the 60,000 plus scientists from around the world that choose to publish with the ACS each year. The journals of the American Chemical Society are stated to have global impact. Indeed, over 6 percent of total articles published by ACS Publications come from outside North America. Journals from ACS Publications are available to scientists at over 5,500 institutional libraries and research centres worldwide: This community downloaded over 71 million peer-reviewed articles and papers from ACS Publications in 2010.

Authors are seen to submit their work to ACS, trusting the publisher’s use of technology to get newly published research into the hands of the scientific community as quickly as possible. The ACS Paragon Plus Environment, its digital review and editing suite, enables quick peer-review and publication. The ACS Web Editions content platform — hosting over one million original research and news articles, and its mobile-friendly app, ACS Mobile for iPhone, iPad, and Android — received awards for innovation from the Association of American Publishers in 2009 and 2011.

The Journal Citation Reports are also stated to affirm ACS’ strategy of introducing new journals that reflect the changing needs of the chemistry community. ACS Nano, introduced in 2007, increased its Impact Factor from 7.493 to 9.855 in 2010. In 2011, ACS Publications will introduce two new journals: ACS Macro Letters, the short-form communication partner to ACS’s existing polymer science publication, Macromolecules, and ACS Synthetic Biology, dedicated to publishing high quality research in the emerging fields of synthetic and systems biology.
