Journal repels a paper on a magnetic material after authorship, funding issues

S03048853

A paper on the properties of a magnetic material is being retracted after including an author without his permission, and omitting a funding source.

According to the note, the work was done in Miao Yu‘s lab at Chongqing University in China; the authors then added Yu’s name to the paper without his authorization, and neglected to list a relevant funding source.

Here’s the retraction note for “Temperature-dependent dynamic mechanical properties of magnetorheological elastomers under magnetic field,” published in the Journal of Magnetism and Magnetic Materials:

Management researcher with 7 retractions issues “clarifications” to 2013 paper

home_cover

The authors of a paper on supportive supervisors just want readers to “better understand the reported findings,” and so have issued multiple “clarifications” in a corrigendum note.

Some of the issues addressed in the note have been raised on PubPeer.

The paper’s author list includes one Fred Walumbwa, formerly an Arizona State University management researcher, some of whose work has succumbed to scrutiny in the the past two years. His current list: seven retractions, a megacorrection, an expression of concern, and now this.

“Unraveling the relationship between family-supportive supervisor and employee performance,” published in Group & Organization Management, has been cited twice, according to Thomson Scientific’s Web of Knowledge.

Here’s the note in full:

Chemists pull non-reproducible paper on method to make opal films

CoverIssue

When two chemists based in China couldn’t reproduce experiments in their paper on opal films, they retracted it.

As the retraction note explains:

In this article we report a method to fabricate 2D TiO2–WO3 composite inverse opal films via a mechanical co-assembly route with a template of polystyrene spheres. Upon repeating the experiments described, we found that this was not an effective method for forming the films; often the film was broken or did not form at all.

The note also explains why the experiment didn’t work:

Duplication shatters two photonic crystal papers

1-s2.0-S0167577X13X00084-cov150h

Two journals published by Elsevier are retracting a pair of material science papers that appear to share figures.

The papers  — in Materials Letters and Optics Communications — discuss photonic crystals, a kind of material used to manipulate light. They share the same first author, Zheng-qi Liu at Jiangxi Normal University and  Nanjing University in China, as well as six other authors. Each paper presents one of the duplicated figures as a slightly different material.

One of the duplicated figures is a a picture of a photonic crystal taken with a scanning electron microscope that gives detail at the level of a few micrometers (it looks like a honeycomb, but it’s composed of tiny spheres). It’s Figure 1a in both papers:

Investigation finds data issues polluted air quality paper

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:

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:

A bacterium may be anti-fungal, but it’s not anti-retraction

The authors of a paper on an anti-fungal bacterium couldn’t ward off a very common problem: plagiarism. The people credited on the paper, published in Applied Microbiology and Biotechnology, apparently weren’t the original authors, according to the retraction note.

We’re not sure who the original authors are. The retraction note doesn’t elaborate much:

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.

“Most responsible course of action is to retract:” Duplicated images fell prostate cancer paper

International Journal of CancerA study on the cellular interactions underlying prostate cancer has been retracted after a whistleblower pointed out duplicated images in one of the paper’s figures that were “erroneously presented as unique.”

The International Journal of Cancer posted the notice in June. The authors backed the paper’s conclusions but agreed, “the most responsible course of action is to retract.”

The notice reads:

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:
