One of the questions we often get — but are careful to answer with some version of “we don’t know because we don’t have a denominator” — is how retraction rates vary by scientific field and country. We’ve noticed that the reasons for retraction seem to vary among countries, but didn’t really have the data. A new paper in the Journal of the Medical Library Association by Kathleen Amos takes a good step toward figuring the country part out.
Cell update: Co-corresponding author let go from Belgian university; retraction notice language changed
We’ve learned more about the circumstances behind a Cell retraction that we covered last week.
First, one of the two corresponding authors left the institution where he most recently worked. Belgium’s VIB Ghent told us that Pankaj Dhonukshe was no longer employed there and said: Read the rest of this entry »
Last spring, we reported on the retraction in Clinical and Translational Allergy of a 2011 paper by researchers in Egypt and Finland after “severe problems in the data set” were uncovered. The notice cited an earlier study, from 2009, in Acta Paediatrica, that formed the basis for the subsequent trial.
It’s never a good sign when a paper has “severe” problems with its data. But when even the researchers are at a loss to explain how those problems made their way into the manuscript, well, that’s downright alarming.
Consider: The journal Clinical and Translational Allergy has retracted a 2011 article by researchers from Egypt and Finland, who have been studying the effects of vitamin C on childhood asthma. In a previous article, published in 2009 in Acta Paediatrica, members of the team reported that Read the rest of this entry »
The news isn’t getting any better for Carsten Carlberg. Earlier this month, Carlberg received a pink slip from the University of Luxembourg in the wake of a data fraud scandal involving a former student named Tatjana Degenhardt. As we wrote last November, journals retracted two of Carlberg’s papers after Degenhardt was found to have fabricated data. Although Degenhardt worked at the University of Kuopio (now the University of Eastern Finland), and Carlberg was not accused of wrongdoing, officials in Luxembourg decided that the mess threatened the public image of their fledgling institution and fired him.
We’d assumed that the University of Eastern Finland considered the matter finished, and that what happened in the Grand Duchy would stay in the Grand Duchy. But we were wrong. Read the rest of this entry »
We’re continuing to try to find out more about the developing story surrounding Carsten Carlberg. Carlberg, as we have reported, was senior author on two papers retracted last year because one of the authors, a graduate student in Carlberg’s lab at the University of Eastern Finland (formerly Kuopio), fabricated data.
Carlberg holds a dual appointment with the University of Luxembourg, which recently announced the results of a months-long investigation into his behavior.
Petter Portin, of the University of Turku, Finland, has been forced to retract four papers because they were duplicates of work he had already published.
Two of those retractions appear in the February 2011 issue of Hereditas. Here’s one retraction notice (link added):
The following article from Hereditas: Portin, P. ‘The effect of the mus309 mutation, defective in DNA double-strand break repair, on crossing over in Drosophila melanogaster suggests a mechanism for interference’, published online in Wiley Online Library (http://onlinelibrary.wiley.com/) on 1 September 2009, Hereditas, volume 146, pp. 162–176, has been retracted by agreement between the author, the Editor-in-Chief, Anssi Saura, and John Wiley & Sons A/S. The retraction has been agreed due to prior publication of a similar article in Genetica.
