A cancer researcher and emeritus professor at The Ohio State University has retracted four more papers, bringing his total to nine from a single journal.
The four retractions of work by Samson Jacob appear in the Journal of Biological Chemistry, from which Jacob retracted five papers in March. The original papers — one of which has been cited more than 250 times — date back to 2002.
When you think a retraction notice doesn’t tell the whole story, what should you do?
For one group of researchers who’ve been closely following how journals handle the work associated with a bone researcher found guilty of misconduct, the actions of one publication were too problematic to let go.
So the researchers wrote to the journal about their concerns, stating a recent retraction notice for a meta-analysis “oversimplifies a complex situation and might be misinterpreted by readers.” And the journal recently published their concerns in a letter to the editor.
The retracted paper is co-authored by researchers who used to collaborate with Yoshihiro Sato, a now-deceased bone researcher who has accrued dozens of retractions. The retraction, issued earlier this year by Acta Neurologica Scandinavica, notes that the meta-analysis cited research by Sato that was “extensively duplicated,” and includes a statement from the first author of the retracted paper, Jun Iwamoto, stating that he was an “honorary author of Sato’s papers,” and played no role in Sato’s scientific misconduct.
A professor specializing in the health of children and pregnant women has left her post at the University of Glasgow, and issued three retractions in recent months.
All three notices — issued by PLOS ONE — mention an investigation at the university, which found signs of data manipulation and falsification. Fiona Lyall, the last author on all three papers, is also the only author in common to all three papers; she did not respond to the journal’s inquiries.
According to the University of Glasgow, the affiliation listed for Lyall, she is no longer based at the university. When we asked about the circumstances of her departure, the spokesperson told us the university has a “commitment to confidentiality,” but noted:
This one gave us pause: A journal recently removed a 1992 paper, providing only a terse explanation — “The above article has been removed at the author’s request.”
Author John Frank Nowikowski tells Retraction Watch he never submitted the article to the Police Journal; it was originally published in the Buenos Aires Herald in Argentina. He asked the journal to remove it because, as a freelance writer, he had expected to be paid for it, but never had been. SAGE purchased the journal from its original publisher, Vathek, in 2014, and agreed to honor the author’s request. But the notice says only that — the 26-year-old article was withdrawn at the author’s request.
