A researcher in Japan who published at least five papers about a deadly 2016 earthquake faked some of the data, Osaka University announced late last week.

Yoshiya Hata resigned his Osaka post and later died, according to media outlet NHK. He claimed to have studied the April 2016 Kumamoto earthquake, which killed at least 50 people, and injured thousands.

In October 2017, we reported that Hiroyuki Goto, of Kyoto University and one of Hata’s co-authors, had apologized because he said that the data contained “wide reaching errors.” One of the papers the two co-authored earned an editor’s note.

Do investigations into research misconduct allegations need better standards? The Association for the Promotion of Research Integrity (APRIN) in Japan, a group of volunteers who “commit themselves to the promotion of research of high integrity” and provide “e-learning material for research ethics education,” thinks so. Today, we present a guest post by Iekuni Ichikawa, who chaired an APRIN committee that recently came up with a new checklist for such investigations, about the effort.

The procedures currently employed by various institutions in Japan are highly variable; hence there is a risk that complainants or respondents might be treated unfairly and that the public might not be informed of the facts of the matters. We organized the Research Misconduct Investigation Standardization Committee of APRIN in July 2017 to propose standardized procedures for handling investigations of alleged research misconduct. Here, we present the “Checklist for Investigating Allegations of Research Misconduct,” the fruits of our discussions.

The Retraction Watch Leaderboard of authors with the most retractions is a frequent source of comment and speculation. Why do only men appear on it? And what fields and countries are represented? Here, Iekuni Ichikawa, Project Professor at Shinshu University and Emeritus Professor of Pediatrics at Vanderbilt University, as well as a co-founder of the Association for the Promotion of Research Integrity (APRIN) in Japan, takes a look at a recent story that referenced our leaderboard — and what those figures really mean.

The authors of Retraction Watch often take pains to point out that the relative rarity of retractions — despite dramatic increases in their rates — make studying them a challenge. But it is often difficult to resist seeking out truth in retraction numbers.

As a case in point, in August Science published an article by Kai Kupferschmidt about research misconduct in Japan that quoted data from the Retraction Watch Leaderboard, pointing that out that although “half of the top 10 are Japanese researchers…only about 5% of published research comes from Japan.” Continue reading When researchers from a particular country dominate retraction statistics, what does it mean?

Last year, an academic society recommended that journals retract nine papers by a researcher in Japan who collaborated with a notorious fraudster. Only two have been retracted.

The researcher is Yuhji Saitoh of Yachiyo Medical Center and Tokyo Women’s Medical University, who co-authored many papers with Yoshitaka Fujii, an anethesiologist who holds the dubious distinction of having retracted more papers than any other. Already, Saitoh has retracted 39 papers, many of which were co-authored by Fujii. But it turns out Saitoh was not an entirely innocent bystander: After receiving allegations of misconduct, the Japanese Society of Anesthesiologists (JSA) investigated approximately 40 publications by Saitoh.  

The JSA investigation into Saitoh’s work was prompted, at least in part, by a 2016 analysis (that we covered) from two anesthesiologists— John Carlisle and John Loadsman—who examined dozens of Saitoh’s papers, 23 of which he didn’t write with Fujii. Carlisle and Loadsman identified several potential concerns with Saitoh’s work, including that it was unlikely the sampling had been conducted randomly.

Earlier this month, Tokushima University in Japan announced it was revoking a student’s PhD degree — but for a somewhat unusual reason.

The student didn’t appear to commit misconduct. Rather, the authors discovered a series of errors that invalidated the paper’s central conclusion.

The case has us wondering about how universities should respond when they discover some of a PhD student’s research is no longer valid — especially when there is no suspicion of misconduct.

Based on our Google translation of the more detailed description of what happened, the university concluded the problem was the result of the authors’ “simple mistakes:”
