Author retracts nanotechnology paper over doubts about key results

without comments

The corresponding author of a 2015 nanotechnology paper has penned a lengthy — and revealing — retraction notice, explaining why he is not certain about the findings.

In the notice, Chang Ming Li from the Institute for Clean Energy & Advanced Materials (ICEAM) at Southwest University in China, states that there is “insufficient evidence to conclusively” identify the composition of the nanowire array described in the article, which “severely undermines the validity of the reported conclusions.”

The 2015 paper has been considered “highly cited” by Clarivate Analytics’ Web of Science, formerly part of Thomson Reuters, meaning it has received a disproportionate amount of cites given its field and publication year.

Li also said that the paper — which appeared in Physical Chemistry, Chemical Physics — was “submitted and published without my knowledge or permission.” He has not responded to our request to explain how that could have happened, given that he was the corresponding author.

First author objects to retraction (his fourth) in chemistry journal

without comments

The first author of a 2013 chemistry paper is objecting to his co-authors’ decision to retract the paper, which contains duplicated figures.

We recently encountered a similar scenario with papers by first author Khalid Mahmood. In late 2015, Mahmood lost three papers in the journal ACS Applied Materials & Interfaces over duplicated images. One of the notices also indicated that the figures had “been published elsewhere and identified with different samples” — the same language used in the notice of the most recent retraction, in Journal of Materials Chemistry C.

Mahmood performed the work on the papers at Korea Advanced Institute of Science and Technology (KAIST), along with his two co-authors, Seung Bin Park and Hyung Jin Sung (also co-authors on two of the retracted papers in ACS Applied Materials & Interfaces).

Seung Bin Park, who is dean of the College of Engineering at KAIST, told us: Read the rest of this entry »

Controversial researcher loses 12th paper that’s “literally copied;” authors object

without comments

A physics journal has retracted a 2011 paper by a group of scientists based in Italy, noting it’s “literally copied” from a paper by the same authors.

This is the 12th retraction for the paper’s first author Alberto Carpinteri, who is known in the engineering community for championing some controversial ideas, such as that the Shroud of Turin is as old as Jesus (contradicting carbon dating). In 2015, a journal he used to edit — Meccanica — retracted 11 of his papers, noting that “the editorial process had been compromised.”

In the latest notice, the Journal of Statistical Mechanics: Theory and Experiment (JSTAT) says its investigation found a substantial portion of the paper—including the main analysis and conclusion—had been lifted from a paper published in another journal several months before.

Last author of the latest paper to be retracted, Amedeo Manuello Bertetto from Polytechnic University of Turin, told us the authors strongly opposed the journal’s decision:  Read the rest of this entry »

Despite author’s protest, journal removes paper on emergency department prices

without comments

A journal has temporarily removed a paper showing the dramatic differences in the cost of providing emergency care that caught national attention (and some criticism from emergency care providers), despite the first author’s claims that the results are valid.

The paper, published online in February by the Annals of Emergency Medicine, showed that it can cost significantly more for patients to be treated at emergency departments than at urgent care centers, even for the same conditions. Soon after the paper was published, first author Vivian Ho at Rice University was told by the American College of Emergency Physicians, which publishes the journal, that there were some errors in the appendix, and they wanted to reanalyze the entire paper.

Ho told us:

PLOS upgrades flag on controversial PACE chronic fatigue syndrome trial; authors “surprised”

with 8 comments

PLOS ONE has issued an expression of concern after the authors of a controversial study about chronic fatigue syndrome declined to share some of their data.

In an unusual move, the journal included the authors’ response to the expression of concern (EOC), in which they strongly argue against the notice, and “do not accept that it is justified.”

In 2015, following public requests to review the data, the journal issued an “editor’s note” on the paper, noting the journal’s policy that authors make data and materials available.

There have been numerous requests for data from the “PACE” trial, as the clinical trial is known. Patients and advocates have long disputed the results, arguing that suggesting cognitive behavior and graded exercise therapy could cause harm.

In the latest notice, the journal says it consulted two editorial board members about the paper, a 2012 sub analysis of a controversial clinical trial on chronic fatigue syndrome. The journal then asked the authors to provide the data behind five tables, which would enable researchers to replicate the cost-effectiveness analyses the authors report for different therapies — including graded exercise therapy, which some patient advocates believe could be harmful.

As with previous requests for data, the authors refused to provide it, citing patient confidentiality and consent. The notice explains:

University suggests journal correct diabetes paper. Publisher retracts it.

with one comment

After a publisher learned there may be issues with a 2008 diabetes paper, it asked the author’s university to investigate. The university found evidence of image duplication, and asked the journal to consider correcting the paper.

Instead, the journal has retracted it.

The backstory involves diabetes researcher Kathrin Maedler, who has one previous retraction, as well as multiple corrections. Even the paper in question, published in Diabetes, received an erratum in 2014 regarding a duplicated image, as well as an expression of concern last August after the American Diabetes Association questioned “the reliability of the data” in both the article and erratum.

According to the expression of concern, the ADA asked the University of Bremen to investigate the issues in the paper. In October, the University of Bremen concluded that several duplications present in her work were the result of negligence, not misconduct.

To resolve the issues, the university’s rector recommended that the authors publish a second erratum with corrected figures. But after conducting its own review, the ADA overruled the university, opting instead to retract the paper:

Author surprised when publisher pulls three of her papers

with 13 comments

A researcher is strongly objecting to a publisher’s decision to retract three of her papers from two computing journals without informing her first.

The reason: Self-plagiarism, which the author said stemmed from her PhD student using similar descriptions for the background sections of the papers. She argued that if the reviewers had flagged the duplication, she would have been happy to revise the papers before publication. A representative of the publisher, Springer, told us the overlap was extensive enough for the journal to determine the papers should be retracted.

We spoke with Sameem Abdul Kareem from the Department Of Artificial Intelligence at the University of Malaya in Malaysia, last author on all three papers, which she co-authored with her former PhD student Haitham Badi (also referred to as Haitham Hasan in several papers). She explained how the duplication occurred:

Busted: Researcher used fake contact info for co-authors

without comments

In February, Lusine Abrahamyan, an assistant professor at the University of Toronto, was contacted by ResearchGate. Her name was listed on a 2016 paper in a heart journal, the site told her — was Abrahamyan indeed a co-author?

Um, no, she was not. In fact, before that moment, she didn’t know such a paper existed.

It turns out, Abrahamyan had supervised the thesis of the first author — who, she soon learned, had also published an identical paper in another heart journal. Both have since been retracted.

How did this happen?

Two retracted papers were published behind bosses’ backs

without comments

Researchers have retracted two 2016 papers from the same journal which were published without the permission of the supervising scientists.

According to the retraction notices, the two Applied Materials & Interfaces articles were “published without the full knowledge or consent of the principal investigators” who guided the research, but are not named in the notices.

The papers share the same three authors, listed in the same order. Last author Fangqiong Tang and middle author Laifeng Li are principal investigators in different labs at the Chinese Academy of Sciences in Beijing. First author Nanjing Hao was formerly in Tang’s research group, but is now at Dartmouth College in New Hampshire.

Here’s the retraction notice for “Fabrication of Carbohydrate-Conjugated Fingerprintlike Mesoporous Silica Net for the Targeted Capture of Bacteria,” which was retracted only months after it was published in November 2016: Read the rest of this entry »

Faked data, plagiarism, no co-author okays…yeah, this paper’s been retracted

with 2 comments

A researcher in South Korea has retracted a 2016 paper on which he is listed as senior author because a former student wrote and published the article without his permission.

According to the retraction notice, the former student also fabricated data and plagiarized “a substantial amount of material” from previous papers published by the senior and middle author.

Here’s the retraction notice for “Oleaginous yeast-based production of microbial oil from volatile fatty acids obtained by anaerobic digestion of red algae (Gelidium amansii),” published in the Korean Journal of Chemical Engineering in April 2016 and retracted in January: Read the rest of this entry »
