Japan, Taiwan taking closer look at fraud — and how to stop it

with 2 comments

Two countries have recently announced plans to learn more about research misconduct, with the goal of preventing it from happening in the first place.

In Japan, the effort takes the form of a joint study group among six universities, which will interview researchers who have engaged in misconduct to discover patterns and common factors for their wrongdoing. In Taiwan, the government recently announced plans to establish an Office of Research Integrity, based on the version in the U.S., to investigate alleged cases of misconduct.

Here’s more about the new Taiwan office, from the Taipei Times:

Columbia University probe prompts retraction of cardiovascular paper

with one comment

A journal has retracted a 2011 study at the request of Columbia University.

According to Jeanine D’Armiento, the study’s last author, the newly retracted paper in Clinical Science contained a figure from a Journal of Hypertension paper published by the same authors earlier that year. 

First and corresponding author Joseph George told Retraction Watch the error was unintentional. A Columbia spokesperson sent us this statement: Read the rest of this entry »

Japan group earns 4th retraction following investigation

without comments

Researchers in Japan have issued their fourth retraction, noting that the same figures were used to depict different experimental conditions.

The group lost two papers in 2015 for the same reason, following a misconduct investigation at Oita University in Japan. Last year, the same group notched another retraction, and pegged the responsibility for the problematic figures on first author Satoshi Hagiwara.

Now, the group has published a fourth retraction in the European Journal of Pharmacologythe latest notice doesn’t identify a culprit. All four retracted papers list Hagiwara as first author.

Here’s the latest retraction notice: Read the rest of this entry »

Lack of reproducibility triggers retractions of Nature Materials articles

without comments

The authors of a highly cited 2015 paper in Nature Materials have retracted it, after being unable to reproduce some of the key findings.

The move prompted the journal to also retract an associated News & Views article.

Here’s the retraction notice for “Fast and long-range triplet exciton diffusion in metal–organic frameworks for photon upconversion at ultralow excitation power:” Read the rest of this entry »

Co-author of retraction record-holder likely fabricated his own data, analysis shows

with 2 comments

In 2012, John Carlisle, a British anesthesiologist, demonstrated conclusively using statistics that Yoshitaka Fujii had faked data in many studies. Fujii — as followers of this blog well know — now holds the record for most retractions by an individual author (183).

Carlisle’s work accomplished two things: It put to rest any doubt that problems with Fujii’s work might have resulted from innocent mistakes, and it gave journals a mathematical tool for conducting investigations into potential cases of misconduct.

Now comes the payoff. In a new paper, Carlisle and another anesthesiologist, John Loadsman, take aim at one of Fujii’s frequent co-authors, Yuhji Saitoh of Yachiyo Medical Center and Tokyo Women’s Medical University in Japan. The pair analyzed data from 31 studies Saitoh published between 1993 and 2012 — including one study that was rejected in 2015 — for a total of 32 papers. Of those, 23 did not include Fujii as an author.

Writing in the journal Anaesthesia, where Carlisle published his first study about Fujii, he and Loadsman state that: Read the rest of this entry »

Catching up: Publisher to pull four papers by retraction record holder flagged years ago

without comments

the-laryngoscopeJournals published by Wiley are retracting four papers by Yoshitaka Fujii, the anesthesiology researcher with the most retracted scientific papers.

Retraction Watch readers will be familiar with Fujii’s case: He currently holds the number one spot on our leaderboard with more than 180 retractions, some of which are pending. (That’s nearly twice the number of retractions by the researcher in the #2 spot, Joachim Boldt.) 

Earlier this year, The Breast Journal and The Laryngoscope — both of which are published by Wiley-Blackwell — issued expressions of concern (EOCs) for a total of four papers by Fujii. All four papers were included in a 2012 analysis of 168 of Fujii’s studies by J. B. Carlisle, a consultant anesthetist in the UK, who concluded that the chance of much of Fujii’s data appearing the way it does naturally is

…the chance of selecting one particular atom from all the human bodies on earth.

Now, both journals are retracting the papers.

University of Tokyo opens investigation into retracted stem cell paper

without comments

KCCY_15_22_COVER.inddThe University of Tokyo is investigating a 2011 stem cell paper in Cell Cycle, recently retracted over irregularities in four figures.

The university has confirmed there is an investigation, but would not specify which paper it concerned; the corresponding author on the paper, however, confirmed to us that it is the focus of the investigation.

In the retraction notice, published Nov. 1, the journal wrote: Read the rest of this entry »

Oops — Springer journals retract three articles published by accident

with one comment

springerJournals published by Springer have retracted three articles in different disciplines, noting in all instances the articles were published by mistake.

A Springer spokesperson told us all three papers were pulled as a result of “human error.” In two instances, the notices say the editors-in-chief never meant to accept the papers, since the recommendation was to reject. 

We’ll start with the retraction that has the most interesting explanation. Here’s the notice: Read the rest of this entry »

Analysis casts doubt on bone researcher’s body of work

with 3 comments

19-coverA new analysis of more than 30 clinical trials co-authored by a bone researcher based in Japan is casting doubt on the legitimacy of the findings.

Yoshihiro Sato, based at Mitate Hospital, has already retracted 12 papers, for reasons ranging from data problems, to including co-authors without their consent, to self-plagiarism. Most of these retracted papers are included in the analysis in the journal Neurology, which concluded that Sato’s 33 randomized clinical trials exhibited patterns that suggest systematic problems with the results.

Other researchers have used similar approaches to analyze a researcher’s body of work — notably, when John Carlisle applied statistical tools to uncover problems in the research of notorious fraudster Yoshitaka Fujii, and Uri Simonsohn, who sniffed out problems with the work of social psychologist  Dirk Smeesters.

Author Mark Bolland of the University of Auckland told us he was surprised by his findings: Read the rest of this entry »

Genetics study flagged for reliability issues by Frontiers journal

with 2 comments

frontiers-in-geneticsA genetics journal has issued an expression of concern (EOC) for a study after an investigation by its chief editors.

According to the notice in Frontiers in Genetics, the authors of the paper — based at Hokkaido University in Sapporo, Japan — are conducting further experiments to resolve the issues raised by the journal’s investigation.

In February, the same paper received a corrigendum due to errors in the assembly of one of the figures.

Here’s the EOC, issued earlier this week: Read the rest of this entry »
