Journal bans 8 authors for plagiarism

67

A medical journal has banned eight authors after discovering that they had published plagiarized work.

We don’t see official author bans as often as we see plagiarism (occasionally, and all the time, respectively). That’s why we’re flagging this case, which is a little old — the International Journal of Medical Science and Public Health announced the ban in March 2015, after it retracted three of the authors’ papers for plagiarism.

All three papers — about recovering from orthopedic problems — have a first author in common: Rajesh Valjibhai Chawda, who was affiliated with the CU Shah Medical College and Hospital in India at the time of the research. (We couldn’t find a webpage for him.)

After an author on one of the original articles alerted the journal of one instance of plagiarism, the journal launched an in-house inquiry, the retraction note explains:

Authors retract striking circadian clock finding after failing to replicate

Screen Shot 2016-03-02 at 9.29.28 AMThe authors of a paper showing a “striking and unanticipated” relationship between light and temperature in regulating circadian rhythms are retracting it when the results couldn’t be replicated.

After being contacted by another group who couldn’t reproduce the data, the authors failed to, as well. They “have absolutely no explanation for the discrepancies with the original results,” according to the note in PLOS Biology.

It’s an unfortunate turn of events, but Continue reading Authors retract striking circadian clock finding after failing to replicate

A highly cited paper by a well-known scientist at the Massachusetts Institute of Technology who studies longevity could have aged better: The ten-year-old paper has earned its second correction.

It’s one of multiple papers by lead author Leonard Guarente that have been questioned on PubPeer. Guarente has already retracted one, and plans to address another. Continue reading Popular paper by famous longevity researcher gets mega-correction

We’re using a common statistical test all wrong. Statisticians want to fix that.

ASA-newlogoAfter reading too many papers that either are not reproducible or contain statistical errors (or both), the American Statistical Association (ASA) has been roused to action. Today the group released six principles for the use and interpretation of p values. P-values are used to search for differences between groups or treatments, to evaluate relationships between variables of interest, and for many other purposes.  But the ASA says they are widely misused. Here are the six principles from the ASA statement:  Continue reading We’re using a common statistical test all wrong. Statisticians want to fix that.

PLOS ONE retracting paper that cites “the Creator”

Screen Shot 2016-01-19 at 10.50.25 AMPLOS ONE has retracted a paper published one month ago after readers began criticizing it for mentioning “the Creator.”

The article “Biomechanical Characteristics of Hand Coordination in Grasping Activities of Daily Living” now includes a reader comment from PLOS Staff, noting: Continue reading PLOS ONE retracting paper that cites “the Creator”

More than half of top-tier economics papers are replicable, study finds

scienceApproximately six out of 10 economics studies published in the field’s most reputable journals — American Economic Review and the Quarterly Journal of Economics — are replicable, according to a study published today in Science.

The authors repeated the results of 18 papers published between 2011 and 2014 and found 11 — approximately 61% — lived up to their claims. But the study found the replicated effect to be on average only 66% of that reported in the earlier studies, which suggests that authors of the original papers may have exaggerated the trends they reported.

Colin Camerer, a behavioral economist at the California Institute of Technology in Pasadena, who co-authored the study, “Evaluating replicability of laboratory experiments in economics,” told us: Continue reading More than half of top-tier economics papers are replicable, study finds

Sample tampering leads to plant scientist’s 7th retraction

Jorge Vivanco
Jorge Vivanco

Plant scientist Jorge Vivanco has earned his seventh retraction, after an investigation found data from soil samples were “intentionally fabricated by a third party.”

Vivanco and his former postdoc Harsh Bais made a name for themselves by discovering the secret behind a nasty invasive plant: It secretes a harmful form of catechin, which kills everything around it, suggesting it could serve as a new herbicide. The findings earned the researchers a story in the New York Times.

In the newly retracted paper, published in 2005, first author Laura Perry — then a postdoc at Colorado State University — further explored the role of the plant-killer, working with Vivanco as the last author. However, when a team working in the building next door had trouble finding catechin in their samples, Perry took another look, and concluded that her samples had been tampered with.

In other words, Perry told us:   Continue reading Sample tampering leads to plant scientist’s 7th retraction

Hands are the “proper design by the Creator,” PLOS ONE paper suggests

Screen Shot 2016-01-19 at 10.50.25 AMA paper about the biomechanics of human hands published last month in PLOS ONE is raising some questions on Twitter, after readers stumbled upon some curious language in the abstract:

The explicit functional link indicates that the biomechanical characteristic of tendinous connective architecture between muscles and articulations is the proper design by the Creator to perform a multitude of daily tasks in a comfortable way.

Yeah, that’s right — “the Creator.” You don’t see such language all that often in academic papers.

Not surprisingly, it’s prompted some harsh reactions from readers: Continue reading Hands are the “proper design by the Creator,” PLOS ONE paper suggests

Molecular self-assembly paper fell apart

1049_soft_matter_f2c-900Authors are retracting a 2014 paper about how liquid-crystalline materials self-organize in low temperature conditions after realizing they had measured the temperatures incorrectly.

The error affected three figures and a table in “Milestone in the NTB phase investigation and beyond: direct insight into molecular self-assembly.” The paper, published in Soft Matter, has been cited three times, according to Thomson Reuters Web of Science.

The retraction note, published in August, offers more detail as to exactly what went wrong:
