Author withdraws entire issue after overseeing his own peer review

home_cover-31The editor and author of most of the papers in a special issue of a math journal told us he is withdrawing the entire issue following revelations that he had coordinated the peer-review process.

The articles, published online earlier this year, recently received an expression of concern after the journal realized the guest editor David Gao, at the Federation University Australia, had coordinated the peer-review process. This was a major no-no, since Gao was also an author of 11 of the 13 papers. Mathematics and Mechanics of Solids slated the articles to be peer reviewed again, by reviewers not chosen by Gao.

Gao told us what happened next, from his perspective — he changed his mind about publishing the papers in MMS:

“Significant errors in the data” stop Hurricane Isaac paper

1-s2.0-S0169809515X0010X-cov150hThis version of Hurricane Isaac — based on the force of nature that hit Louisiana in 2012 —  didn’t get very far. Atmospheric Research has retracted a paper on a simulation of the hurricane just a few months after it was published.

The paper included two features that commonly get a paper retracted: erroneous data, and a dispute over authorship.

The 2014 paper only has one author: O. Alizadeh-Choobari, a climatologist at the University of Tehran.

Here’s the retraction note, which provides a few more details on what went wrong:

Can journals get hijacked? Apparently, yes

science pic.mag.current-issueDid you recently log onto your favorite journal’s website and see this? (For anyone who doesn’t want to bother clicking, it’s the video from Rick Astley’s “Never Gonna Give You Up.”) If so, your favorite journal was hijacked.

In today’s issue of Science, John Bohannon (who recently published a bogus study about the benefits of chocolate) explains how easy it is to take over a journal’s website — so easy, in fact, that he did it himself. And he’s not the only one, he reports: Continue reading Can journals get hijacked? Apparently, yes

Making error detection easier – and more automated: A guest post from the co-developer of “statcheck”

We’re pleased to present a guest post from Michèle B. Nuijten, a PhD student at Tilburg University who helped develop a program called “statcheck,” which automatically spots statistical mistakes in psychology papers, making it significantly easier to find flaws. Nuijten writes about how such a program came about, and its implications for other fields.

Readers of Retraction Watch know that the literature contains way too many errors – to a great extent, as some research suggests, in my field of psychology. And there is evidence that problem is only likely to get worse.

To reliably investigate these claims, we wanted to study reporting inconsistencies at a large scale. However, extracting statistical results from papers and recalculating the p-values is not only very tedious, it also takes a LOT of time.

So we created a program known as “statcheck” to do the checking for us, by automatically extracting statistics from papers and recalculating p-values. Unfortunately, we recently found that our suspicions were correct: Half of the papers in psychology contain at least one statistical reporting inconsistency, and one in eight papers contain an inconsistency that might have affected the statistical conclusion.

The origins of statcheck began in 2011, Continue reading Making error detection easier – and more automated: A guest post from the co-developer of “statcheck”

Plagiarism detected in two papers on improving detection of cancer by mammograms

8 (1)

A group of computer scientists has a pair of retractions for duplicating “substantial parts” of other articles written by different authors. Both papers, published in Neural Computing and Applications, are on ways to screen for breast cancer more effectively.

According to the abstract of  “An improved data mining technique for classification and detection of breast cancer from mammograms,” computers make the process of identifying cancer in lesions detected by mammograms faster and more accurate:

Although general rules for the differentiation between benign and malignant breast lesion exist, only 15–30% of masses referred for surgical biopsy are actually malignant. Physician experience of detecting breast cancer can be assisted by using some computerized feature extraction and classification algorithms. Computer-aided classification system was used to help in diagnosing abnormalities faster than traditional screening program without the drawback attribute to human factors.

The article has been cited four times, according to Thomson Scientific’s Web of Knowledge.  The retraction note reveals where “substantial parts” of the article came from:

BMC retracts paper by scientist who banned use of his software by immigrant-friendly countries

Screen Shot 2015-11-10 at 12.24.42 PMA BioMed Central journal has pulled the paper of a scientist who decided to prohibit countries that are friendly to immigrants from using his software.

Recently, German scientist Gangolf Jobb declared that starting on October 1st scientists working in countries that are, in his opinion, too welcoming to immigrants — including Great Britain, France and Germany — could no longer use his Treefinder software, which creates trees showing potential evolutionary relationships between species. He’d already banned its use by U.S. scientists in February, citing the country’s “imperialism.” Last week, BMC Evolutionary Biology pulled the paper describing the software, noting it now “breaches the journal’s editorial policy on software availability.”

Many scientists have used Jobb’s software: The BMC paper that describes it, “TREEFINDER: a powerful graphical analysis environment for molecular phylogenetics,” has been cited 745 times since it was published in 2004, according to Thomson Scientific’s Web of Knowledge.

Jobb told Retraction Watch that the software is still available to any scientist willing to travel to non-banned countries, and that he does not care about the retraction: Continue reading BMC retracts paper by scientist who banned use of his software by immigrant-friendly countries

Intellectual property issues sink cancer paper in JACS

176 spine minimum. full size. Editor: Lingling JEM: Leslie RTP: Michael ReidThe authors of a paper on a mechanism for potential cancer therapies are retracting it after realizing they published some proprietary findings “without permission and agreement from St. Jude Children’s Research Hospital.”

According to the retraction note in Journal of the American Chemical Society, the authors included an X-ray crystal structure and data that were gathered at St. Jude’s and considered the hospital’s intellectual property. On the paper, the last author, Zhengding Su, listed an affiliation at St. Jude and Hubei University of Technology in China, along with Amersino Biodevelop Inc., based in Waterloo, Canada.

Author’s coordination of peer review flags 13 math papers

home_cover (3)Thirteen papers in Mathematics and Mechanics of Solids now have an expression of concern, after it came to light that an author on most of the papers coordinated the peer-review process.

David Y. Gao, a well-known and prolific mathematician at the Federation University Australia, is the author of 11 of the papers, and also the guest editor of the special issue in which they were set to appear. The papers were published online earlier this year.

A spokesperson for SAGE, which publishes the journal, confirmed that the publisher decided to re-review the papers after learning about Gao’s role in the peer-review process:

Authors retract highly cited Nature quantum dot letter after discovering error

cover_nature

Authors have retracted a highly cited Nature letter that purported to discover a much sought-after, stable light source from quantum dots, after they realized the light was actually coming from another source: the glass the dots were affixed to.

When the paper “Non-blinking semiconductor nanocrystals” was published in 2009, it received some media coverage, such as in Chemistry World. That’s partly because very small sources of “non-blinking” light could have wide-ranging, big-picture applications, author Todd Krauss, a physical chemist at the University of Rochester, told us:

Off the top of my head, a quantum computer. Quantum cryptography is another one. People want a stable light source that obeys quantum physics, instead of classic physics.

The retraction note, published Wednesday, explains how the researchers found out the effect was coming from the glass, not quantum dots:

Retraction strikes power grid paper with “almost identical” content to previous study

EnergiesAn electrical engineering paper published in April has been retracted because of similarities to a 2012 paper from different authors, including “almost identical” data in two of the papers’ tables.

The authors were unable to provide the original numbers for the suspect tables, along with a pair of “similar” figures, which bore a striking resemblance to ones presented in the same 2012 paper. Corresponding author Tao Jin at Fuzhou University in China requested the withdrawal “in order to repeat the experiments and obtain new data.”

Energies posted the retraction October 1.

Here’s it is, in full:
