Lancet issues expression of concern for 2011 Macchiarini paper

The Lancet has tagged an expression of concern onto a seminal 2011 paper by Paolo Macchiarini, the Italian surgeon whose work and conduct outside the operating room has earned months of  heavy criticism that recently culminated in his dismissal from the Karolinska Institutet.

“Tracheobronchial transplantation with a stem-cell-seeded bioartificial nanocomposite: a proof-of-concept study,” which described the first case of a transplant using an artificial trachea seeded with the patient’s own stem cells, now bears an expression of concern from The Lancet editors, citing ongoing investigations. The journal has also removed three more authors from the paper, upon their request.

The expression of concern essentially presents the timeline of the controversy that led the journal to make this move:

Concerns attached to three more papers by retraction-laden management researcher

Fred Walumbwa
Fred Walumbwa

Fred Walumbwa, a management researcher with eight seven retractions, has received three expressions of concern from two journals after he failed to provide raw data following an investigation into potential errors.

In the past, Walumbwa has said he only keeps data until his papers are published, but a lack of raw data has become a common theme in his notices, which now also include four corrections, and one other EOC (making a new total of four). There are no standard rules about how long to store raw data, but one journal that issued two of the new EOCs has since updated its submission policy to require that authors keep data for at least five years.

Walumbwa currently works at Florida International University. When concerns about the statistics were raised about five of his papers in Personnel Psychology, the journal conducted an investigation that led to flagging two of those articles, the expression of concern explains:

Poop paper flushed due to possible sample contamination

cover (3)The authors of a paper on a new probiotic strain of bacteria found in pig feces have retracted it from Animal Science Journal after discovering some of the bacteria might have been contaminated.

Readers likely know by now how easy it is for this to happen, as we frequently report on retractions due to similar reasons. Like other instances of mistaken cell identity, the authors of this 2013 paper realized the mistake following further tests of the bacteria used in the experiment.

What if we tried to replicate papers before they’re published?

We all know replicability is a problem – consistently, many papers in various fields fail to replicate when put to the test. But instead of testing findings after they’ve gone through the rigorous and laborious process of publication, why not verify them beforehand, so that only replicable findings make their way into the literature? That is the principle behind a recent initiative called The Pipeline Project (covered in The Atlantic today), in which 25 labs checked 10 unpublished studies from the lab of one researcher in social psychology. We spoke with that researcher, Eric Uhlmann (also last author on the paper), and first author Martin Schweinsberg, both based at INSEAD.

Neuroscientist pleads guilty in court to fraud, gets two-year suspended sentence

Bruce Murdoch

A Parkinson’s researcher pleaded guilty to fraud in court this morning in Brisbane, Australia, and received a two-year suspended sentence.

Court sentences for fraud are rare, to say the least. This one follows an investigation by Bruce Murdoch‘s former employer, the University of Queensland, into 92 papers — resulting in the retraction of three papers co-authored by Caroline Barwood, also facing fraud charges. The investigation was unable to find any evidence that published research cited in court had been ever carried out.

The Australian reported this morning that Murdoch:

How much do oil spills cost? Controversy over paper oozes into larger debate

622871A controversy surrounding a 2014 Journal of Environmental Management paper has tapped into a larger scientific and economic issue — how to tally up the damage after an oil spill.

The original paper, called “A revealed preference approach to valuing non-market recreational fishing losses from the Deepwater Horizon oil spill,” estimates the 2010 explosion of the BP-owned drilling rig cost the Gulf-Coast recreational saltwater angler fishing industry alone nearly $600 million. But Kenneth Train, an economics professor at the University of California, Berkeley has questioned the methods used — both publicly, in a comment that was published in the Journal of Environmental Management, and privately through personal calls with the authors. The first author says Train asked them to retract the paper; he denies ever making that request. While Train, in his comment, says he doubts the accuracy of the $600 million estimate, he does not provide an alternative number.

Train was hired to review the study by BP, which owned the well that spilled millions of oil barrels into the Gulf.

Calculating the cost of oil spills is controversial. Since the Exxon Valdez spill in 1989, Continue reading How much do oil spills cost? Controversy over paper oozes into larger debate

Upon request, NEJM added note to help Texas distance itself from Planned Parenthood article

The New England Journal of Medicine added a disclaimer to a recent article about the effects of funding cuts to Planned Parenthood, after a request from the Texas Health and Human Services Commission, saying it wanted to distance itself from the paper.

Since the paper was published in February, one author has stepped down from his position at HHSC after facing disciplinary action.

The article suggested that birth rates among a group of lower-income women increased after the state cut down on support for Planned Parenthood. It drew a significant amount of media attention — and concern from the HHSC, which asked the journal to add a disclaimer to the article soon after publication. The journal complied, but embargoed the announcement of the change until 5 p.m. eastern time today.

Here’s the disclaimer that NEJM added to the article:

Denmark court clears controversial psychologist of misconduct charges

A Danish court has determined that psychologist Helmuth Nyborg did not commit misconduct in a controversial 2011 paper which predicted an influx of immigrants into Denmark would lower the population’s average IQ by the latter part of this century.

The ruling, reported by the Danish newspaper Politiken, overturns a previous finding of misconduct by the the Danish Committees for Scientific Dishonesty (DCSD). It’s yet another example of scientists bringing academic disputes to the courthouse — just last year, a Danish court overturned another misconduct ruling by the DCSD against physiologist Bente Klarlund Pedersen.

The 2011 paper by Nyborg, “The Decay of Western Civilization: Double Relaxed Darwinian Selection,” appeared in Personality and Individual Differences, and quickly aroused concerns in a group of Danish scientists. The main charges: That the article denied authorship to another author, and misused a reference.

As first reported in the Danish press, an inquiry by the Danish Committees for Scientific Dishonesty (DCSD) concluded in 2013 that: Continue reading Denmark court clears controversial psychologist of misconduct charges

Study on teens with scoliosis failed to seek ethics approval, erratum notes

Screen Shot 2016-03-07 at 3.29.57 PMAfter researchers failed to seek ethics approval for a study on teens with scoliosis, a journal has issued an erratum to the paper.

The journal is not retracting the paper outright, it says, because the study was non-invasive and likely would have received ethics approval.

During the study, teenagers with and without progressive scoliosis underwent a physical examination and participated in an interview along with a parent, with the goal of trying to uncover risk factors for the condition.

Here’s the full erratum from Scoliosis and Spinal Disorders for “Physical activities of Patients with adolescent idiopathic scoliosis (AIS): preliminary longitudinal case–control study historical evaluation of possible risk factors:”

Concerns about image manipulation? Sorry, the data were lost in a flood

1 (1)Lost your data? Blame nature.

Microchimica Acta has retracted a paper about water-soluble quantum dots after the authors couldn’t provide back-up for a figure that contained signs of manipulation. The reason, the editor told us: The corresponding author said the raw data were lost in a flood in Sri Lanka.

The journal asked the authors for the data after an investigation suggested that the paper included copied pictures of the same nanoparticle. The paper is one of four by the pair of co-authors flagged on PubPeer for potential image duplication.

Here’s the retraction note for “CdS/ZnS core-shell quantum dots capped with mercaptoacetic acid as fluorescent probes for Hg(II) ions:”
