‘We badly need to change processes’: How ‘slow, opaque and inconsistent’ journals’ responses to misconduct can be

Two researchers from Japan — Jun Iwamoto and the late Yoshihiro Sato — have slowly crept up our leaderboard of retractions to positions 3 and 4. They have that dubious distinction because a group of researchers from the University of Auckland the University of Aberdeen, who have spent years analyzing the work. As their efforts continue, … Continue reading ‘We badly need to change processes’: How ‘slow, opaque and inconsistent’ journals’ responses to misconduct can be

Journal expresses a great deal of concern over deceased author’s work

A gastroenterology journal has issued an extensive expression of concern about a 2013 paper by Yoshihiro Sato, a Japanese endocrinologist who has posthumously been climbing the Retraction Watch leaderboard. (He’s now ranked number three, ahead of Diederik Stapel.) To call the statement an “expression of concern” is like calling Charles M. Schulz a talented cartoonist, … Continue reading Journal expresses a great deal of concern over deceased author’s work

How often do authors with retractions for misconduct continue to publish?

How does retraction change publishing behavior? Mark Bolland and Andrew Grey, who were two members of a team whose work led to dozens of retractions for Yoshihiro Sato, now third on the Retraction Watch leaderboard, joined forces with Vyoma Mistry to find out. We asked Bolland to answer several questions about the new University of … Continue reading How often do authors with retractions for misconduct continue to publish?

New study finds “important deficiencies” in university reports of misconduct

Retraction Watch readers may recall the name Yoshihiro Sato. The late researcher’s retraction total — now at 51 — gives him the number four spot on our leaderboard. He’s there because of the work of four researchers, Andrew Grey, Mark Bolland, and Greg Gamble, all of the University of Auckland, and Alison Avenell, of the … Continue reading New study finds “important deficiencies” in university reports of misconduct

Journal editors still don’t like talking about misconduct. And that’s a problem.

In early 2011, less than six months after we launched Retraction Watch, we came across a retraction from a surgery journal. The notice was scant on details, so co-founder Adam Marcus called the editor to ask why the paper had been retracted. The answer: “It’s none of your damn business.” It turns out that’s still … Continue reading Journal editors still don’t like talking about misconduct. And that’s a problem.

Meet the scientific sleuths: More than two dozen who’ve had an impact on the scientific literature

Over the years, we have written about a number of the sleuths who, on their own time and often at great risks to their careers or finances, have looked for issues in the scientific literature. Here’s a sampling:

Caught Our Notice: No retraction for “likely fraudulent” study

Title: Homocysteine as a predictive factor for hip fracture in elderly women with Parkinson’s disease What Caught Our Attention:  In a letter to the editor, researchers led by Mark Bolland recently outlined the many reasons why a study by Yoshihiro Sato and colleagues in The American Journal of Medicine was “unreliable,” including evidence that the … Continue reading Caught Our Notice: No retraction for “likely fraudulent” study

Bone researcher is up to 17 retractions

A bone researcher has lost three more papers for scientific misconduct. The new retractions bring Yoshihiro Sato’s total to 17 and put him on our Leaderboard. According to the retraction notices, Sato asked the Journal of Neurology, Neurosurgery, and Psychiatry to retract three of his papers “due to scientific misconduct.” In the letter, Sato—who is corresponding … Continue reading Bone researcher is up to 17 retractions

A shadow was cast on a bone researcher’s work. What are journals doing about his papers?

Last year, a researcher cast doubt on a bone scientist’s clinical trials, suggesting some of the findings may not be legitimate. So what’s happened since? Since 2015, journals have retracted 14 papers by bone researcher Yoshihiro Sato, based at Mitate Hospital in Japan, for issues ranging from self-plagiarism, to problems with data, to including co-authors without their consent. … Continue reading A shadow was cast on a bone researcher’s work.

Fraud by bone researcher takes down two meta-analyses, a clinical trial, and review

The troubles continue for a bone researcher, who’s lost multiple papers in recent months due to problems ranging from data issues to including authors without their consent. Now, journals have retracted two more papers by Yoshihiro Sato. And in a sign of the downstream effects that fraud can have, another journal has retracted two meta-analyses by other … Continue reading Fraud by bone researcher takes down two meta-analyses, a clinical trial, and review
