Diederik Stapel

Recently, we reported that social psychologist and renowned data faker Diederik Stapel had found himself a new gig supporting research at a vocational university in the Netherlands — but it appears that was short-lived.

According to multiple news reports, NHTV Breda will not be employing Stapel, after all.

Here’s why more than 50,000 psychology studies are about to have PubPeer entries

with 13 comments

pubpeerPubPeer will see a surge of more than 50,000 entries for psychology studies in the next few weeks as part of an initiative that aims to identify statistical mistakes in academic literature.

The detection process uses the algorithm “statcheck” — which we’ve covered previously in a guest post by one of its co-developers — to scan just under 700,000 results from the large sample of psychology studies. Although the trends in Hartgerink’s present data are yet to be explored, his previous research suggests that around half of psychology papers have at least one statistical error, and one in eight have mistakes that affect their statistical conclusions. In the current effort, regardless of whether any mistakes are found, the results from the checks are then posted to PubPeer, and authors are alerted through an email.

Till now, the initiative is one of the biggest large-scale post-publication peer review efforts of its kind. Some researchers are, however, concerned about its current process of detecting potential mistakes, particularly the fact that potentially stigmatizing entries are created even if no errors are found.

Dental paper pulled for “wrong content with serious consequences”

without comments

Clinical Oral InvestigationsAn article on how missing teeth affect chewing was — well, pulled — when someone noticed a few errors. The journal later published a corrected version.

The retraction for “Chewing ability in an adult Chinese population” appeared in Clinical Oral Investigations in 2012, but we’re sharing it with you now because the notice contains some remarkable language:

This article has been withdrawn due to wrong content with serious consequences such as danger to people’s health.

Last author Nico H.J. Creugers, who works at Radboud University Medical Center in the Netherlands, told us:

Leiden requests two retractions over misconduct

with 5 comments

logo-lumc-engThe Leiden University Medical Center (LUMC) has asked a journal to retract two papers after revealing a former employee manipulated data.

The report does not name the individual nor the journal, but notes that they work in a molecular field, and are currently employed by a university outside The Netherlands.

Editors say they missed “fairly obvious clues” of third party tampering, publish fake peer reviews

with 14 comments

BJCP Cover

The editors of a journal that recently retracted a paper after the peer-review process was “compromised” have published the fake reviews, along with additional details about the case.

In the editorial titled “Organised crime against the academic peer review system,” Adam Cohen and other editors at the British Journal of Clinical Pharmacology say they missed “several fairly obvious clues that should have set alarm bells ringing.” For instance, the glowing reviews from supposed high-profile researchers at Ivy League institutions were returned within a few days, were riddled with grammar problems, and the authors had no previous publications. 

The case is one of many we’ve recently seen in which papers are pulled due to actions of a third party

The paper was submitted on August 5, 2015. From the beginning, the timing was suspect, Cohen — the director for the Centre for Human Drug Research in The Netherlands — and his colleagues note: Read the rest of this entry »

Dutch university ordered to pay economist after she was accused of plagiarism

with one comment

VU UniversityA court in the Netherlands has fined Vrije Universiteit Amsterdam (VU) 7,500 euros to compensate for “immaterial damage” to an economist accused of plagiarism.

Karima Kourtita researcher at VU, has been at the receiving end of anonymous complaints to her institution accusing her of plagiarism and her professor, high-profile economist Peter Nijkamp, of duplication (i.e. self-plagiarism). Kourtit is now seeking to prosecute the unnamed source of the complaint for defamation; the VU told us it will no longer accept fully anonymous complaints.

The case began when VU cancelled Kourtit’s thesis defense for plagiarism, and a report published on the VSNU, the Association of Universities, accused Nijkamp of self-plagiarism. Two of Nijkamp’s papers have been retracted as a result of the investigation; Kourtit is an author on one of the retracted papers.

A VU spokesperson told us:

How much does a retracted result pollute the field?

with 2 comments

Research Integrity and Peer Review

When a paper is retracted, how many other papers in the same field — which either cite the finding or cite other papers that do — are affected?

That’s the question examined by a study published in BioMed Central’s new journal, Research Integrity and Peer Review. Using the case of a paper retracted from Nature in 2014, the authors found that subsequent research that cites the retracted paper often repeats the problematic finding, thereby spreading it throughout the field. However, papers that indirectly cited the retracted result — by citing the papers that cited the Nature paper, but not the Nature paper itself — typically don’t repeat the retracted result, which limits its spread.

Here’s how the authors describe their findings in the paper: Read the rest of this entry »

Journal retracts bioelectronics paper for lack of credit to collaborators

with 2 comments

S09565663The list of co-authors on a paper about a “bioelectronic composite” was apparently too sparse.

According to its retraction note — posted at the request of the editor-in-chief and the corresponding author — the paper failed to include some of the collaborators.

The Biosensors & Bioelectronics paper looks at a protein complex that could function as part of a “bio-hybrid” device, like a sensor or a solar cell. It has been cited only by its retraction according to Thomson Reuters Web of Science.

What went wrong in allotting credit for the work pretty straightforward, according to the note for “Monolayers of pigment–protein complexes on a bare gold electrode: Orientation controlled deposition and comparison of electron transfer rate for two configurations.” Here it is in full:

Psychologist Jens Förster earns second and third retractions as part of settlement

Jens Förster

High-profile social psychologist Jens Förster has earned two retractions following an investigation by his former workplace. He agreed to the retractions as part of a settlement with the German Society for Psychology (DGPs).

The papers are two of eight that were found to contain “strong statistical evidence for low veracity.” According to the report from an expert panel convened at the request of the board of the University of Amsterdam, following

an extensive statistical analysis, the experts conclude that many of the experiments described in the articles show an exceptionally linear link. This linearity is not only surprising, but often also too good to be true because it is at odds with the random variation within the experiments.

One of those eight papers was retracted in 2014. In November, the American Psychology Association received an appeal to keep two of the papers, and Förster agreed to the retractions of two more:
