Two math papers are too similar, both retracted

Advances in Differential EquationsA mathematician has lost two publications that overlap substantially.

In this case, it’s easy to see how editors were duped (as it were). Both journals received the papers within a few months of each other, and then published them in quick succession; both have since been retracted. The papers share a first author, Jin Li, affiliated with Jiujiang University in China.

How similar are Li’s papers? See for yourself.

Here’s the abstract for “Landesman-Lazer type condition for second-order differential equations at resonance with impulsive effects,” received by Advances in Difference Equations in June 2014 and published in September 2014: Continue reading Two math papers are too similar, both retracted

Duplicated data gets corrected — not retracted — by psych journal

Psychological Science

A psychology journal is correcting a paper for reusing data. The editor told us the paper is a “piecemeal publication,” not a duplicate, and is distinct enough from the previous article that it is not “grounds for retraction.”

The authors tracked the health and mood of 65 patients over nine weeks. In one paper, they concluded that measures of physical well being and psychosocial well being positively predict one another; in the other (the now corrected paper), they concluded that health and mood (along with positive emotions) influence each other in a self-sustaining dynamic.

As a press release for the now-corrected paper put it: Continue reading Duplicated data gets corrected — not retracted — by psych journal

Author threatens to sue Elsevier if paper remains retracted

Computational Materials Science

An author is prepared to sue Elsevier if it doesn’t un-retract his paper.

Computational Materials Science published two papers by the same author just eight months apart; nearly four years later, the journal pulled one for duplication. Author Masoud Panjepour, affiliated with Isfahan University of Technology in Iran, told us that he is working with a lawyer to negotiate a solution. However, if the publisher does not un-retract the paper, he does “not rule out filing a lawsuit.”

Here’s the retraction notice for “The effect of temperature on the grain growth of nanocrystalline metals and its simulation by molecular dynamics method,” which appeared last November:

Researcher who sued to stop retractions gets his sixth

A sixth retraction has appeared for a diabetes researcher who previously sued a publisher to try to stop his papers from being retracted.

Mario Saad‘s latest retraction, in PLOS Biology, stems from inadvertent duplications, according to the authors.  Though an investigation at Saad’s institution — the University of Campinas in Brazil — found no evidence of misconduct, a critic of the paper told The Scientist he does not believe that the issues with blots were inadvertent.

Previously, Saad sued the American Diabetes Association to remove four expressions of concern from his papers; they were later retracted, even though Unicamp recommended keeping three of them published.

Here’s the new retraction notice, for “Gut Microbiota Is a Key Modulator of Insulin Resistance in TLR 2 Knockout Mice:” Continue reading Researcher who sued to stop retractions gets his sixth

PLOS ONE pulls maize paper with Photoshopped images

PLOS OnePLOS ONE has retracted a paper after editors learned that some of the images had been manipulated using Photoshop.

First author of the paper, Chuan Li, confirmed that he was responsible, and told Retraction Watch he apologizes for his “low-level mistake.”

Zhongfu Ni, last author of the paper from the China Agricultural University in Beijing, told us that all the co-authors agree with the retraction.

Here’s the retraction notice: Continue reading PLOS ONE pulls maize paper with Photoshopped images

“Mixed up” images earn biologists four retractions

525480Four different journals have pulled papers from the same authors due to alleged duplication or manipulation of images.

All four papers have two authors in common — Jianting Miao and Wei Zhang, both based at The Fourth Military Medical University in Xi’an City, Shaanxi, China. Many of the other co-authors are also listed in two or three of the retracted papers.

Miao claims that the photographs got “mixed up” due to the researchers’ “great carelessness” and “insufficient knowledge.” He told us:

Biologist under investigation asks journal to swap image, journal retracts the paper

When a researcher discovered one of the images in her papers was a duplication, she asked the journal to fix it — but the journal decided to retract the paper entirely.

The researcher, Suchitra Sumitran-Holgersson, is currently being investigated by the University of Gothenburg in Sweden after a number of her papers were questioned on PubPeer. She told us the duplication was the result of ‘‘genuine human error.’’ Tissue Engineering Part A, however, decided the request to swap the image was a ‘‘cause for concern,’’ and chose to retract the paper. 

Here’s the retraction notice:

Oops — journal published same paper three times

surface interface analysisOn November 25, 2014, a journal published an article on mass spectrometry. Then on December 18th they published it again — twice.

Yes: “Mass analysis by Ar-GCIB-dynamic SIMS for organic materials” was mistakenly published a total of three times.

Over a year later, the journal pulled the two redundant publications. Here’s the retraction notice for one of them:

Non-retraction notice: Editors explain why two similar papers aren’t redundant

abdominal radiologyEditors have published a notice to let readers know why they’re not retracting a couple of papers.

One paper examined whether the results of CT scans could be used to stage patients with uterine carcinoma; the other considered whether CT scans could be used to predict overall survival in uterine carcinoma. Both papers — by researchers at the Memorial Sloan Kettering Cancer Center — used data from the same 193 women. After they appeared in in different journals, the editors considered whether they were redundant — a quality that can spell retraction for a paper.

The editors explain why they decided the papers were unique in a brief commentary — a non-retraction notice, if you will — published in a third journal, Abdominal Radiology:

Materials journal breaks three papers from the same author

Metals and Materials Journal.

Metals and Materials International has retracted three papers from one author, due to suspicions of plagiarism and authorship issues.

The three papers have one thing in common — the same lead author, Reza Haghayeghi from the Islamic Azad University in Tehran, Iran.

The retraction notices — all released in March, 2016 — lead with the following:
