What do studies of retractions tell us?

jmbeThe Journal of Microbiology & Biology Education has published a special issue on scientific ethics, and it includes an invited piece from us.

In “What Studies of Retractions Tell Us,” we decided to do a literature review of the small but growing field of retraction studies. Five years ago, this would have been a very short paper, consisting of a handful of references, but we were able to find about 30 studies to include quite easily.

Here’s the abstract: Continue reading What do studies of retractions tell us?

“You don’t retract a paper, you retract the results within:” Why one scientist still displays one of his mistakes

And now, one from the archives.

In 1989, then MIT grad student Lance Fortnow (he’s now chair of the computer science department at Georgia Tech) wrote a mathematical proof and published it as conference proceedings. He later went to publish the proof in a journal.

But he then discovered “unexpected technical challenges” and published a retraction in 1997. Both are still available on his personal website.

Not everyone would be that transparent. We reached out to ask why he left them up for people to see. He gave us his rationale: Continue reading “You don’t retract a paper, you retract the results within:” Why one scientist still displays one of his mistakes

ORI sanctions former University of Chicago and UCSF scientists for faking findings

The stories behind several recent inscrutable retraction notices became a bit more clear today when the Office of Research Integrity (ORI) issued findings in cases involving former researchers at the University of Chicago and the University of California, San Francisco.

The ORI found that H. Rosie Xing, a former assistant professor at the University of Chicago, Continue reading ORI sanctions former University of Chicago and UCSF scientists for faking findings

Bruce Murdoch, a neuroscientist formerly of the University of Queensland, will appear in court next week to face fraud charges stemming from an investigation that has already led to three retractions, several corrections, and similar charges for one of his colleagues.

Here’s the notice from the Crime and Corruption Commission: Continue reading Second former University of Queensland researcher to appear in court to face fraud charges

Dentistry student loses travel grant for duplicating his own work

iadrThe International Association for Dental Research has retracted a student travel award after discovering that the recipient had previously published the work he used to secure the grant, including in an abstract he presented at the same conference last year.

The self-plagiarism was uncovered by an anonymous group of students at the Hong Kong University dentistry school, where the student is a PhD student. The unnamed students sent both the IADR and HKU faculty members a color-coded chart showing identical phrases between the 2014 abstract, a 2013 paper published in the Journal of Periodontal Research called “Human umbilical vein endothelial cells synergize osteo/odontogenic differentiation of periodontal ligament stem cells in 3D cell sheets,” and another abstract the authors presented at the 2013 IADR conference.

The paper and both abstracts were written by P.K.C.P. Panduwawala, who lost the travel grant, along with HKU’s former dean of dentistry L.P. Samaranayake; HKU’s associate dean for research L.J. Jin; and C.F. Zhang, part of HKU’s tissue engineering group.

The IADR’s page now lists the winners with a note at the bottom: Continue reading Dentistry student loses travel grant for duplicating his own work

Non-renewable resource: Fuel yanks paper for duplication

fuel30420Fuel, an Elsevier title, has pulled an article on coal pollution because the authors took much of the work from an earlier paper of theirs in another journal.

The article, “Co-firing of coal and biomass: Development of a conceptual model for ash formation prediction,” was published in September by a group from Australia and The Netherlands.

According to the notice: Continue reading Non-renewable resource: Fuel yanks paper for duplication

Phantom authorship forces retraction of electron paper

ULTRAMICUltramicroscopy has retracted a paper it published earlier this year after the corresponding author admitted to submitting the paper without the consent of his colleagues.

The article, “The post-peak spectra in electron energy loss near edge structure,” came from a group led by one Feng Tian, a materials scientist at Shanghai University for Science and Technology. The other authors were Peter Shattschneider and Micheal Stoger-Pollach, of the Vienna University of Technology. Except that they weren’t.

According to the retraction notice: Continue reading Phantom authorship forces retraction of electron paper

COPD paper in JCI retracted following PubPeer critiques
