Osteoporosis paper felled by concerns with “scientific integrity”

with one comment

cover (3)

A paper suggesting that exposure to sunlight might help prevent hip fractures in the elderly has been retracted, due to duplication and “concerns about the underlying data.”

An expression of concern that appeared last July flagged the 2005 paper as containing text that matched another paper with the same first author that was published in 2011. According to the publisher, that duplicated text sparked a closer look at the text, which raised concerns about the scientific integrity of the paper.

The retraction note, published by the Journal of Bone and Mineral Research, says that the first author was responsible for the content of the paper: Read the rest of this entry »

Cropped, spliced image leads to a PLOS One correction

without comments

Screen Shot 2015-10-01 at 4.27.21 PMA PLOS One paper on morphine treatment for cancer cells has a couple issues with figures, prompting a massive correction — what we affectionately call a “mega-correction” — by the journal.

In one figure, there was “an undisclosed splice.” Another figure contained two panels that were “mistakenly from the same sample.”

The 2013 paper in question, “Chronic Morphine Treatment Attenuates Cell Growth of Human BT474 Breast Cancer Cells by Rearrangement of the ErbB Signalling Network,” has been cited four times, according to Thomson Scientific’s Web of Knowledge.

Here’s the correction:

Investigation finds data issues polluted air quality paper

with 2 comments

1-s2.0-S0013935113X0009X-cov150hAn investigation at the Queensland University of Technology in Australia has found that a paper on air pollution and human health contains a host of issues with the data and its analysis. The paper has been retracted with a very detailed note from Environmental Research.

The issues with the paper include an “incorrect analysis of the data,” and its failure to properly cite multiple papers and one researcher’s contributions. Ultimately, according to the retraction note, the investigation found that the “conclusions of the paper are flawed.”

“Submicrometer particles and their effects on the association between air temperature and mortality in Brisbane, Australia” has been cited three times, according to Thomson Scientific’s Web of Knowledge.

The retraction note is very, very detailed. It outlines the problems with the paper:

Honest errors take down math paper

with one comment

1-s2.0-S0022247X15X00217-cov150hAn incorrect proof has felled a math paper. There’s not too much to say in a straightforward situation like this one, which we’ve seen before — the result of honest errors, not any malfeasance.

Here’s the abstract for “Spectral mapping theorem for generalized Kato spectrum:”

In this paper, we give an affirmative answer to Mbekhta’s conjecture (Mbekhta, 1990) about the pseudo Fredholm operators in Hilbert space. As a consequence, we characterize pseudo Fredholm operators and we prove that the generalized Kato spectrum satisfies the spectral mapping theorem in the Hilbert spaces setting.

The paper — published in the Journal of Mathematical Analysis and Applications — has been cited twice, according to Thomson Scientific’s Web of Knowledge.

Here’s the retraction note:

Prominent nutrition researcher Marion Nestle retracting recent article

with 2 comments

jphp_journal_coverProminent nutrition expert Marion Nestle is pulling an opinion piece she recently co-authored in the Journal of Public Health Policy following revelations that the piece contained multiple factual errors and failed to reveal her co-author’s ties to one of the subjects of the article.

The article, “The food industry and conflicts of interest in nutrition research: A Latin American perspective,” was published October 29 and raised concerns about the conflicts of interest that can occur when a food company pairs with a public health organization. Specifically, the article critiqued the supposed relationship between the biggest beverage distributor in Guatemala and the leading Guatemala-based public health organization, aligned to distribute a fortified supplement for undernourished children.

However, after the paper appeared, Nestle learned they had misrepresented the relationship between the key parties, and failed to disclose that her co-author, Joaquin Barnoya, received “a substantial portion of his salary” from INCAP. Retracting the opinion was the best solution, Nestle wrote on her blog today: Read the rest of this entry »

Black hole paper by teenaged prodigy retracted for duplication

with one comment

Screen Shot 2015-11-25 at 8.39.44 AMAn astrophysics journal is retracting a paper on black holes whose first author is a teenager about to earn his PhD, after learning the paper “draws extensively” from a book chapter by the last author.

Many papers are pulled for duplication, but few get a news release from the publisher about it. In a move that we approve of, the editors of The Astrophysical Journal announced the forthcoming retraction on the American Astronomical Society (AAS) website.

The paper‘s first author Song Yoo-Geun who turns 18 this month, and is on track to earn his doctorate next year from the University of Science and Technology in South Korea. According to the news release, the paper borrows heavily from a book chapter published in 2002 by his adviser and co-author, Seok Jae Park at the Korea Astronomy and Space Science Institute.

AAS is handling this very quickly. The paper was published in October, someone alerted the journal to the duplication on November 14, and the announcement of the retraction went up on the AAS website just ten days later.

The retraction note for “Axisymmetric nonstationary black hole magnetospheres: revisited” will be published in the next issue of ApJ. In the meantime, the news release explains what happened:

Now this is good news: In policy change, JBC will now make retraction notices informative

with 8 comments

47.coverReaders of this blog know that we have had a few stock villains over the years. High on the list has been the Journal of Biological Chemistry (JBC), and we’ve criticized repeatedly the journal’s unwillingness to provide any information about the reasons for retractions. For as long as we’ve been around, the JBC’s stock retraction statement seemed to be:

This article has been withdrawn by the authors.

Times have changed. According to an editorial published earlier this month, the JBC says it will now be giving readers as much information as possible about the retraction notices it prints. The editorial, written by interim editor-in-chief F. Peter Guengerich of Vanderbilt University, alludes to the heat the journal has been taking about its opacity: Read the rest of this entry »

Author withdraws entire issue after overseeing his own peer review

without comments

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:

New Retraction Watch partnership will create retraction database

with 8 comments

cos_logoAs our readers know, one of the goals of our work at Retraction Watch is to create a free, comprehensive database of retractions. That effort is generously funded by The John D. and Catherine T. MacArthur Foundation and The Laura and John Arnold Foundation.

Today, we’re excited to announce that our parent organization, The Center For Scientific Integrity (CSI), has partnered with The Center For Open Science (COS) to create that database on the Open Science Framework (OSF).

It’s a natural collaboration, says Retraction Watch co-founder and CSI executive director Ivan Oransky:
