The editor, Artemi Cerdà of the University of Valencia in Spain, has also disappeared from the list of editors at two journals published by the European Geophysical Union, which recently announced that one of its editors had engaged in citation manipulation.

Here’s a statement we just received from a spokesperson for Wiley, which publishes Land Degradation & Development:

with 3 comments

An editor at two European Geophysical Union journals has resigned following revelations that he or she engaged in citation manipulation — boosting citations to his or her own papers and associated journals.

Here’s a letter announcing the news, signed by EGU publication committee chair Hubert Savenije, that ran in several EGU journals earlier this week: Read the rest of this entry »

How to spot a “citation cartel”

with 7 comments

Iztok Fister Jr

Do you know the difference between a group of researchers in the same field who cite each other’s related work, and a group of authors who purposefully cite each other in order to boost their own profiles? It’s not easy to do, say researchers in a new article about so-called “Citation cartels.” In Frontiers in Physics, Matjaz Perc and two Iztok Fisters (Senior and Junior) from the University of Maribor in Slovenia present an algorithm to help identify groups of researchers citing each other for overly collegial reasons. (For more on the phenomenon, see a recent column in STAT by our co-founders.) We spoke with first author Iztok Fister Jr.

Retraction Watch: What exactly are “citation cartels”? How do they differ from groups of researchers in the same field who tend to cite each other because their research is related in some way, without any nefarious intent? Read the rest of this entry »

Authors in 2014 peer review ring lose 4 more papers each for “compromised” review

without comments

human factors and ergonomicsA journal is pulling additional papers authored by twin brothers for peer review issues.

After retracting three papers by Cheng-Wu Chen earlier this year for “compromised” peer reviewHuman Factors and Ergonomics in Manufacturing & Service Industries is now pulling four more by Chen for the same reason — and four others by his twin brother, Chen-Yuan Chen, who was a the center of a peer review ring that SAGE busted in 2014.

Cheng-Wu Chen lost 21 papers during that episode. He’s now up to 28; Chen-Yuan Chen, who also goes by Peter Chen, is now up to 43. Both are present on our leaderboard.

The notes, which appear in the March/April issue of the journal, are all identical, and also cite issues with citations:

Crime journal’s meteoric rise due to questionable self-citation: analysis

with 3 comments

JCJShould it be a crime for editors to cite work in their own journal?

Last year, the Journal of Criminal Justice became the top-ranked journal in the field of criminology, but critics say that its meteoric rise is due in part to the editor’s penchant for self-citation.

As Thomas Baker of the University of Central Florida, writes in the September/October issue of the The Criminologist, a newsletter of the American Society of Criminology: Read the rest of this entry »

Citation manipulation the last straw for modified rice straw paper

with one comment

jnm_coverThe Journal of Nanomaterials has retracted a paper on modified rice straw over citation manipulation.

Rice straw, which makes up nearly half of the biomass in rice plants, is generally considered agricultural waste. However, in recent years scientists have discovered ways to modify the raw material to make it capable of absorbing heavy metal ions, making it useful to both prevent and clean up pollution from industrial processes.

The retracted paper, which analyzed the physical properties of different kinds of modified rice straw, was retracted for citation manipulation.

Here’s the short (and to the point) retraction for “Mechanical and Thermal Stability Properties of Modified Rice Straw Fiber Blend with Polycaprolactone Composite”: Read the rest of this entry »

Refreshing honesty? Journal asks authors to help game its impact factor

with 18 comments

homepageImage_en_USWe and others have documented plenty of cases where papers get retracted because authors manipulate citations to boost their impact factor.

Sometimes, journal publishers pressure authors to cite papers within the journal to artificially inflate its impact factor. Since this is highly discouraged – COPE has extensive commentary on the problem – it usually happens behind closed doors.

Since we’re all about transparency, we were delighted to discover that the Thammasat International Journal of Science and Technologya publication out of Thammasat University in Thailand, lists the policy up front: Read the rest of this entry »

Citation manipulation: Journal retracts paper because author boosted references to a journal he edits

with 5 comments

jpdcA group of researchers have lost a paper in a computer science journal because they were apparently using its references to help the impact factor of a different journal that one of them edits.

Here’s the notice for “Impacts of sensor node distributions on coverage in sensor networks,” a paper first published in 2011 and cited four times, according to Thomson Scientific’s Web of Knowledge: Read the rest of this entry »

Medical journal guilty of citation manipulation retracts two “inadequate” review articles

without comments

clinicsThe Brazilian medical journal Clinics — edited by the Faculdade de Medicina of the University of São Paulo — has lost two more papers in a citation stacking scheme that cost one of the authors his job as editor of the publication.

The first paper, by former editor Mauricio Rocha-e-Silva and Ariane Gomes, was titled “An overview of recently published medical papers in Brazilian scientific journals,” and was published in 2011. As the retraction notice states: Read the rest of this entry »
