Cancer researcher has dodged accusations for decades (and has a new correction)

with 34 comments

Today isn’t a great day for Carlo Croce, chair of the department of cancer biology and genetics at The Ohio State University (OSU).

The New York Times has a lengthy article detailing the misconduct accusations that have swirled around Croce for years. We’ve covered many, but The Gray Lady obtained documents that show there have been many more.

The story mentions a 2013 letter from Ohio State University to pseudonymous whistleblower Clare Francis (which we reported on in 2014), acknowledging Francis’s allegations against Croce. However, in the letter, an administrator said OSU saw no reason to investigate Croce.

The story didn’t stop there, as the Times reports:

Something new: A journal publishes running tally of retractions

without comments

Here’s something we haven’t seen before: A journal based in Serbia recently began listing all the articles it has retracted, all due to plagiarism.

Although preventing plagiarism is hardly a new goal for journals, creating a web page dedicated to retractions is certainly a novel attempt. (Even the home page has a link to the page, called “Retracted Articles.”)

This past February, the Journal of Process Management – New Technologies International did exactly that. Currently, this page on the journal’s website features five papers, all retracted in 2016, along with links to notices which indicate the original, plagiarized article.

First, let’s list the notice for “Impact of shopper’s creativeness on shopping methods: A case-study of students of University of Delhi (India),” published in 2014:

Faked data, plagiarism, no co-author okays…yeah, this paper’s been retracted

with 2 comments

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: Read the rest of this entry »

Paper quickly retracted after author used another group’s work

without comments

The author of a 2016 paper has agreed to retract it after an investigation revealed that most of the article came from another research group at the same university.

According to the notice, the author based the majority of his paper on results generated by other scientists without their permission.

Here’s the retraction notice for “Controlled synthesis of magnetic block copolymers for anti-microbial purpose,” published in the Journal of Applied Polymer Science in November and retracted in February: Read the rest of this entry »

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

with one comment

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:

Whistleblower gets court backing in defamation case — but at a cost

with 4 comments

It’s been a long and winding road for a whistleblower at Indiana University, South Bend.

After Mark Fox, a professor of management and entrepreneurship accused two business professors of plagiarism in 2012, a university investigation found one of the two men — Douglas Agbetsiafa, the former chair of the economics department — guilty of plagiarism, and terminated him in January 2014. The other professor was cleared of any wrongdoing — then sued Fox for defamation in June, 2014.

Fox won the case, but it dragged on. More than two years later, in December 2016, the Indiana Supreme Court declined to hear an appeal.

Fox told us:

Journals pull two papers after blogger shares plagiarism suspicions

with 4 comments

Journals have retracted two papers after they were flagged by a pseudonymous blogger, who suspected all had copied text from other sources.

What’s more, a third paper seems to have simply disappeared from the journal’s website, after the blogger, Neuroskeptic, alerted the journal to the text overlap.

Neuroskeptic became suspicious about the three unrelated papers – about food chemistry, heart disease, and the immune system and cancer – after scanning them with plagiarism software. After alerting the journals, two issued formal retractions for the papers – but neither specifies plagiarism as the reason.

The retractions were the result of a larger project, Neuroskeptic told us:

Plant biologist loses three papers that made up a duplication ring

with one comment

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:

JAMA article on zinc for the common cold retracted

with one comment

Authors have retracted a JAMA article summarizing the evidence behind the benefits of a supplement, after the systemic review upon which it was based was withdrawn.

The 2014 paper, “Oral Zinc for the Common Cold,” drew from a 2013 Cochrane Review, considered the gold standard for rigorous analyses of clinical treatments. That Cochrane review was withdrawn last year, a decision that the editors upheld this past September. Both were co-authored by Rashmi Ranjan Das, of the All India Institute of Medical Sciences, in Bhubaneswar, and Meenu Singh, of the Post-Graduate Institute of Medical Education and Research, in Chandigarh, India.

JAMA editor in chief Howard Bauchner told Retraction Watch that this week’s retraction followed an investigation by the journal: Read the rest of this entry »

Lesson not learned: Researchers copied a master’s thesis — twice

without comments

A material science journal has retracted a paper after learning the authors took most of the content from a master’s thesis – and added the author as a co-author without his knowledge.

The authors must have really liked this thesis – they lost another paper in 2015 for copying from the same document.

Both retracted articles were co-authored by three researchers in the Department of Civil Engineering at Shahid Rajaee Teacher Training University in Tehran, Iran. The first author, Saeed Ghaffarpour Jahromi, serves as the University’s Dean of Faculty in the School of Civil Engineering.

Simon Hesp, a professor in the Department of Chemistry at Queens University in Kingston, Ontario, told Retraction Watch that he had notified both journals about the plagiarism when he recognized the thesis of Benjamin James Smith, who was a master’s student in his lab from 1998 to 2000. Hesp told us: Read the rest of this entry »
