Most citations to retracted papers don’t note they’re problematic, authors say

Gali Halevi

We’ve known for a while that too many researchers cite retracted papers. But in what context do those citations occur? Are some authors citing a retracted paper as an example of problematic findings, or do most citing authors treat the findings as legitimate, failing to realize they are no longer valid? In a new paper in Scientometrics, Gali Halevi at Icahn School of Medicine at Mount Sinai in New York and Judit Bar-Ilan at Bar-Ilan University in Israel examined citations to 15 papers retracted in 2014. Halevi told us why she was surprised to see how many authors don’t realize retracted papers are problematic, and what the publishing community can do to get the word out.

Retraction Watch: We’ve noticed that many papers are cited long after being retracted, without notifying readers the paper is problematic. You looked at citations to retracted papers and tracked how the citing authors described the paper – noting that its findings were problematic given the retraction (negative), or treating the findings as legitimate research that affirms the newer paper’s results (positive). The vast majority of post-retraction citations – 83% — were positive. Did that surprise you?

Prominent NIH researcher up to a dozen retractions

Neuroscientist Stanley Rapoport hasn’t had much luck with his co-authors.

Recently, we’ve reported on multiple retractions of papers co-authored by Rapoport after three different first authors were found to have committed misconduct. Now, the fallout from one of those cases had led to four more retractions, bringing Rapoport’s total to 12.

The latest batch of retractions stem from the actions of Jagadeesh Rao.

Here’s the first notice, issued by Psychopharmacology:

Faked data, plagiarism, no co-author okays…yeah, this paper’s been retracted

A researcher in South Korea has retracted a 2016 paper on which he is listed as senior author because a former student wrote and published the article without his permission.

According to the retraction notice, the former student also fabricated data and plagiarized “a substantial amount of material” from previous papers published by the senior and middle author.

Here’s the retraction notice for “Oleaginous yeast-based production of microbial oil from volatile fatty acids obtained by anaerobic digestion of red algae (Gelidium amansii),” published in the Korean Journal of Chemical Engineering in April 2016 and retracted in January: Continue reading Faked data, plagiarism, no co-author okays…yeah, this paper’s been retracted

Students withdraw report of private stem cell retreat

Master’s students have retracted a review of an internal meeting of stem cell researchers because it contained confidential information.

According to the Managing Director of the society, Stem Cell Network North Rhine Westphalia (NRW), the event was not open to the public, and the authors had not contacted either the society or the scientists they cited before publishing the report.

Here’s the retraction notice for “A Report on the Internal Retreat Meeting of the Stem Cell Network North Rhine Westphalia,” published online in Molecular Biotechnology on October 31 and retracted shortly after on December 14: Continue reading Students withdraw report of private stem cell retreat

Authors contest retractions for “high degrees of similarity” with previous papers

A group of researchers has lost two papers due to “high degrees of similarity with previously published works,” according to the notices.

The authors are objecting to the retractions, however, arguing the journal never gave them an opportunity to show their work is different from the previous papers.

Both papers were published in the International Journal of Plastics Technology, and share the same three authors, all based at Charan Singh University in India. They were retracted by the Editor in Chief, according to the notices.

Effect of dynamic cross-linking on melt rheological properties of isotactic polypropylene (iPP)/ethylene–propylene diene rubber (EPDM)/nitrile rubber (NBR) elastomeric blends” was published in 2011. Here’s the retraction notice:

How did a book chapter end up with two authors who didn’t contribute to it?

An erratum for a book chapter about water pollution has removed two out of the three original authors. 

What’s more, the notice specifies that “any mistakes or omissions are the sole responsibility” of the remaining author, Michael Yodzis of the University of Guelph in Ontario, Canada. 

This isn’t something we see every day, but one of the removed authors told us he believes the paper is scientifically valid — he just didn’t have anything to do with it. Yodzis told us he included the two authors by mistake, after believing he had corresponded with them about the paper, which was an extension of their previous work together.

Here’s the erratum, issued in December: Continue reading How did a book chapter end up with two authors who didn’t contribute to it?

Study of child with rare cancer retracted due to lack of parental consent

Researchers in Ireland have retracted a case study about a rare type of cancer in a child because – contrary to what they claimed in the paper – they had not obtained the necessary permission from the parents.

In the June 2016 article, the authors stated they had received “written informed consent” from the parents to publish the case. But according to the retraction notice — issued just a few months later in October — that was not the case.

Here’s the retraction notice for “Paediatric Ewing-like sarcoma arising from the cranium – a unique diagnostic challenge,” which for legal reasons, the publisher has withdrawn from public view:

Plant biologist loses three papers that made up a duplication ring

A biologist in India has lost three papers that appear to have been part of a network of duplications.

One paper published in 2012 was retracted — at the researcher’s request — for copying from a 2010 paper of his. In turn, both papers were duplicated in a paper that was published in 2016, and retracted a few months later. That 2016 paper borrowed from another paper published last year, which was quickly retracted after we contacted the journal.

These papers — by Dilip Kumar Das, listed at T. M. Bhagalpur University in India — were flagged in March by a PubPeer commenter.

In December, Plant Cell, Tissue and Organ Culture (PCTOC) retracted Das’s 2012 paper; here’s the retraction notice:

Geoscience paper pulled over apparent lack of company consent

A 2016 paper has been retracted at the request of a company that provides geoscience solutions because the authors—who are employees of the company—included proprietary information and didn’t obtain proper permission.

Often in extenuating circumstances such as publishing something without permission, the article is taken offline. But this article, which according to the retraction notice “contains information, data and intellectual property belonging to the company and its client,” remains available. What’s more, the authors seem to think they had the company’s okay to publish.

Here’s the complete retraction notice for “High resolution seismic imaging of complex structures: a case study of the South China Sea data” published by Marine Geophysical Research:

Nuclear fuel container material isn’t as novel as it appeared in now-retracted paper

A paper describing the construction of a material that could be used in nuclear fuel containers has been retracted after the authors left out key details.

According to the editor, the omission made the authors’ method seem more novel than it was.

The material is described in “Structure and Mechanical Properties of Thick Copper Coating Made by Cold Spray.” It was published in the January 2016 issue of the Journal of Thermal Spray Technology.

According to the retraction notice, the authors did not specify in the paper how the first layer of copper was sprayed onto the steel:
