Second paper falls for ex-Leiden researcher accused of fraud

atrdLast November we wrote about the retraction of a 2010 paper in PNAS by Annemie Schuerwegh and colleagues. Schuerwegh had been fired from Leiden University in The Netherlands for fraud, which said there would be a second retraction coming.

It has.

The article, “Anti-citrullinated protein antibodies in rheumatoid arthritis: a functional role for mast cells and basophils?” had appeared in the Annals of the Rheumatic Diseases. According to the retraction notice: Continue reading Second paper falls for ex-Leiden researcher accused of fraud

“Gremlins” caused errors in climate change paper showing gains from global warming

jep_coverThe author of a controversial 2009 paper arguing that at least some amount of global warming could lead to economic gains has corrected the paper, along with a later article in a different journal. We confess to be baffled by the implications of the mix-up, although others appear to be less confused.

The 2009 article, “The Economic Effects of Climate Change,” was written by Richard Tol, of the University of Sussex, and appeared in the Journal of Economic Perspectives. It has been cited 91 times, according to Thomson Scientific’s Web of Science.

Here’s the abstract:

Birds of a feather: Duplication grounds migration paper

wemcoverA group of bird researchers in China has lost their article in Wetlands Ecology and Management on the migratory habits of shorebirds after the editors of the journal learned that they’d cobbled the paper together from their own previously published work.

The article by Song et. al., “Ecological stability of the shorebird stopover site in the Yalu River Estuary Wetlands, China,” had appeared online in February.

BMJ authors take back inaccurate statin safety statements

bmjcover514Last October, the BMJ published a paper by a group of researchers from the United States and Canada questioning the use of statins in patients considered at low risk of cardiovascular disease.

The article has been cited eight times since then, according to Thomson Scientific’s Web of Knowledge. It mentioned data from another study that reported a high rate of side effects in patients who used the drugs, between 18% and 20% — suggesting that those who received little or no benefit from the therapy could be more more likely to suffer harm than good.

But that citation turns out to have been flawed — prompting the journal to take the unusual step of removing those “statements” from the article and another it published about the issue that has been cited six times. And in an editorial, BMJ editor Fiona Godlee said she has asked a panel of experts to review the original paper to determine if it ought to be retracted completely: Continue reading BMJ authors take back inaccurate statin safety statements

The “sins and virtues of authors span a rather colorful palette”: New editor yanks plagiarized paper

scientometricsWhat a difference a new editor can make.

Consider the case of a paper in Scientometrics that came to the attention earlier this year of Jeffrey Beall.

Beall, a research librarian and scourge of the predatory publishing world, had previously posted on his blog about his frustrations with the journal’s seeming indifference to the word theft. (He also helped bring about another plagiarism retraction we covered earlier this year.)

The article was titled “Educational reforms and internationalization of universities: evidence from major regions of the world,” and was written by a group from China and Pakistan.It has been cited just once, according to Thomson Scientific’s Web of Knowledge, by another paper in Scientometrics.

“I never manipulated data”: Förster defends actions in open letter

Jens Förster

Jens Förster, the Dutch social psychologist accused of misconduct, has posted an open letter on his lab’s website in which he denies wrongdoing.

The letter, in English and dated May 11, offers a detailed rebuttal to the investigation’s conclusions. It also offers a rationale for Förster’s decision not to post his data on the Internet. And it’s followed by a briefer letter from Nira Liberman, who identifies herself as a collaborator of Förster’s.

We present the letter in full below:
