Last summer, a journal retracted another paper by the pair, also citing suspicions of image manipulation. The latest batch of retractions — issued by seven different journals — includes some papers that have been questioned on PubPeer.
Dibyendu Talukdar, listed at the University of Calcutta in West Bengal, India, is the sole author on three retracted papers. He shares five new retractions with Tulika Talukdar listed at the University of North Bengal. That brings their totals to nine and six, respectively. (We’re not sure if the Drs. Talukdar are related).
We’ll start with the papers they share: Read the rest of this entry »
According to the most recent retraction notices, issued by Applied Surface Science, the four papers duplicated several figures and portions of text from the authors’ previous works. Although the notices do not single out a responsible party, last year the Mumbai Mirror reported that first and corresponding Naba K. Sahoo had been accused of duplication by colleagues at the Bhabha Atomic Research Centre (BARC), part of Indian government’s Department of Atomic Energy.
(In a bizarre twist, Sahoo also made the news recently for getting into a fist fight with another BARC scientist.)
Sahoo received two retractions last year for duplication, sometimes inelegantly referred to as “self-plagiarism.” All six of his retractions affect papers published by Applied Surface Science between 2005 and 2007.
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:
One paper published in 2012 was retracted — at the researcher’s request — for copying from a 2010 paper of his.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:
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 »
One retraction notice in Applied Surface Science says a duplicate of the paper was previously published by the same author — N. K. Sahoo, a researcher at the Bhabha Atomic Research Centre (BARC), which is part of the Indian government’s Department of Atomic Energy in Trombay, Mumbai. The other notice, which appears in Optical Materials, notes that the study “for the most part” has appeared in another paper by Sahoo.
Despite concerns about his work, Sahoo was promoted in May, according to the Mumbai Mirror. As a result, members of the Bhabha Atomic Research Officers’ Association wrote to BARC director K. N. Vyas asking for the institution to take action against Sahoo. A member of the group told the Mumbai Mirror in August: Read the rest of this entry »
Longtime Retraction Watch readers may recall that in 2013, we were forced to temporarily remove ten posts following a false — and frankly ridiculous — copyright infringement claim.
Well, it’s happened again.
On Wednesday, our host, Bluehost, forwarded us another false copyright claim — aka a Digital Millennium Copyright Act (DMCA) takedown notice — by someone calling himself “Jiya Khan” and claiming to be based in Delhi, India. (Well, specifically, in “Rohini,sector-12,” which would mean that he or she is based at one of two petrol stations.)
What actually happened, in an eerie echo of the 2013 case, is that Read the rest of this entry »
Mukund Jagannathan, the journal’s editor-in-chief and a plastic surgeon in India, told Retraction Watch:
The patient wrote to the editor, mentioning that her photo was present in the article originally published, and politely asked us to remove her photos from public display on the Internet.
Asked whether the journal considered issuing a partial retraction to only hide the patient’s identity, Jagannathan said: Read the rest of this entry »
According to an editor’s note, published in Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, the journal received confirmation from all three authors that the aforementioned researcher should be removed from the author list during proofing stage. However, the researcher whose name was omitted — Nahid Nishat of the Jamia Millia Islamia in Jamia Nagar, New Delhi, India — later contacted the journal claiming that she didn’t okay this move.
Nishat told Retraction Watch that she believes the two listed authors on the paper wrote to the journal on her behalf to remove her name: Read the rest of this entry »
According to the notice, when the authors continued their research on the same topic, some of the new data raised concerns about what was reported in the 2010 paper. That set off a “number of disputes between authors,” which led them to retract the paper.
This account was supported by the study’s first and corresponding author, Naitik Trivedi, from the A.R. College of Pharmacy & G.H. Patel Institute of Pharmacy in Anand, Gujarat, India. Trivedi told us he believes the previous study didn’t include some relevant parameters, which affected the results.
Trivedi noted that all the authors agree to the retraction, adding: Read the rest of this entry »
