When someone has to retract a paper for misconduct, what are the odds they will do it again? And how can we use that information to stop repeat offenders? Those are the questions that Toshio Kuroki of the Japan Society for the Promotion of Science and Akira Ukawa of RIKEN set out to tackle in their new paper, appearing in Accountability in Research. Not surprisingly, they found that people with multiple retractions are more likely than others to have another — and when people have at least five retractions, the odds are significantly higher.
Retraction Watch: Why did you decide to examine the chances of researchers retracting additional papers?
Kyoto University has “punitively dismissed” a researcher found guilty of falsifying nearly all of the figures in a 2017 stem cell paper.
According to an announcement Wednesday, the university fired the paper’s corresponding author, Kohei Yamamizu, after determining he had fabricated and falsified datain all but one figure in the 2017 Stem Cell Reportspaper. The findings of the investigation, which were announced in January, found that Yamamizu, whoworked at the Center for iPS Cell Research and Application (CiRA), was the only person responsible for the manipulation.
When researchers submitted a paper about a type of microparticle to PNAS, they wanted to give credit where it was due, and cite an unpublished manuscript that helped guide their work. But the journal’s policy forbid citing unpublished work, and the reference was removed before publication. Now, concerns from the authors of that unpublished work have prompted the journal to have a change of heart.
An investigation by Kyoto University in Japan has found a researcher guilty of falsifying all but one of the figures in a 2017 stem cell paper.
Yesterday, Kyoto Universityannounced that the paper’s first author, Kohei Yamamizu, had fabricated and falsified datain the Stem Cell Reportspaper. According to the investigation report, none of the other authors were involved in the data manipulation.
Yamamizu works at the Center for iPS cell Research and Application (CiRA) at Kyoto University, directed by Shinya Yamanaka, a Nobel Prize winner for his pioneering work in stem cell biology.
A spokesperson for the journal told us that the authors disclosed the problems last week and Stem Cell Reports will be retracting the paper, published last February.
A university in Japan dismissed a researcher earlier this month after a probe uncovered evidence of image falsification in several of his papers.
The immunology researcher, Masashi Emoto, denied any wrongdoing. He has said that the experiments in question were performed by another researcher and “he was not responsible” for the falsification.
In 2013, Emoto filed a suit against Gunma University, in which he claimed another researcher possessed the raw data for the experiments in question. Emoto requested those documents be returned to him. However, the court determined that Emoto possessed the raw data.
According to the report — released by Gunma University on October 11 — without the raw data, the university could not prove Emoto committed the misconduct. However, the university determined that, as the corresponding author on the four papers, Emoto was responsible for the work.
But, in late September 2017, one of the authors—Hiroyuki Goto—revealed that the Kumamoto Earthquake data contained “wide reaching errors”—and an outside expert had warned him the data might be problematic nine months earlier.
Goto, an associate professor in the Disaster Prevention Research Institute at Kyoto University, issued two statements in which he acknowledged the errors, but did not indicate how they occurred. According to The Japan Times, Japan’s Ministry of Education, Culture, Sports, Science and Technology is investigating whether the data “was falsified or fabricated due to inconsistencies with other readings taken nearby.” A report in another Japanese paper, The Mainichi, notes that Osaka University—where one of the authors, Yoshiya Hata, works—is looking into the matter as well.
