No longer in limbo: Journal lifts 2015 expression of concern from chemistry paper

All too often, when an article is flagged by a journal that’s concerned about the findings, the notice lingers in limbo, leaving readers unclear whether or not to rely on the findings. One chemistry paper’s two-year stint in purgatory ended last month, when the journal lifted its expression of concern (EOC) and replaced it with a correction.

The journal chose to swap the 2015 EOC with a correction after the authors addressed its concerns in a follow-up paper, also published in Organic & Biomolecular Chemistry.

The journal’s executive editor Richard Kelly provided further insights about what happened:

Hello…Newman: Yet another sting pranks a predatory journal, Seinfeld-style

John McCool

Starting to get bored of stings designed to expose the well-documented flaws in scientific publishing? Yeah, sometimes we are too. But another one just came across our desks, and we couldn’t help ourselves.

John McCool is neither a researcher nor a urologist. When received an unsolicited invitation to submit a paper to an open-access urology journal, however, he just couldn’t resist: He is the owner of a freelance scientific editing company, and has long been concerned about so-called predatory journals, which often publish sub-par papers as long as authors pay. And he loves the TV show “Seinfeld.”

Like many others before him, McCool decided to punk the journal by submitting a fake paper. He told us:

Most citations to retracted papers don’t note they’re problematic, authors say

Gali Halevi

We’ve known for a while that too many researchers cite retracted papers. But in what context do those citations occur? Are some authors citing a retracted paper as an example of problematic findings, or do most citing authors treat the findings as legitimate, failing to realize they are no longer valid? In a new paper in Scientometrics, Gali Halevi at Icahn School of Medicine at Mount Sinai in New York and Judit Bar-Ilan at Bar-Ilan University in Israel examined citations to 15 papers retracted in 2014. Halevi told us why she was surprised to see how many authors don’t realize retracted papers are problematic, and what the publishing community can do to get the word out.

Retraction Watch: We’ve noticed that many papers are cited long after being retracted, without notifying readers the paper is problematic. You looked at citations to retracted papers and tracked how the citing authors described the paper – noting that its findings were problematic given the retraction (negative), or treating the findings as legitimate research that affirms the newer paper’s results (positive). The vast majority of post-retraction citations – 83% — were positive. Did that surprise you?

Once-prominent researcher logs retraction following misconduct finding

A researcher who resigned from the University of Dundee in Scotland after it concluded he was guilty of misconduct has issued his first retraction.

According to an internal email to staff forwarded to us last year, the university concluded that Robert Ryan had misrepresented clinical data and images in 12 different publications. The first retraction, published by Molecular Microbiology, cites image duplications in multiple figures.

Here’s the full notice:

Journals retract paper, flag two others by cancer doc under investigation

Carlo Croce

This weekend, Carlo Croce had some reprieve from the misconduct accusations that have followed him for years (recently described in a lengthy article in the New York Times) and that have prompted his university to re-open an investigation. On Sunday, he received a prestigious award from the American Association for Cancer Research, honoring his work.

But the moment may have been short-lived. Today, Croce received two expressions of concern (EOCs) from PNAS for two well-cited papers published over a decade ago, on which Croce — chair of the Department of Cancer Biology and Genetics at The Ohio State University (OSU) — is last author. The two EOCs cite concerns over duplicated bands. What’s more, another journal recently decided to retract one of his papers, citing figures that didn’t represent the results of the experiments.

PNAS chose to issue EOCs, rather than retractions or corrections, because the authors didn’t agree that the bands were duplicated, according to executive editor Diane Sullenberger. She explained how the journal learned of the issues with the two papers: Continue reading Journals retract paper, flag two others by cancer doc under investigation

Five retractions for engineering duo in South Korea over duplication, fraudulent data

An engineering student in South Korea and a professor have retracted five papers from four different journals for reasons ranging from figure duplication to manipulated or fraudulent data.

Jae Hyo Park, who is pursuing his PhD, and Seung Ki Joo, a professor in the department of material science and engineering at Seoul National University in South Korea, appear on all five papers as first and last author, respectively.

According to an official at IOP Publishing, the retractions began when a third party contacted them last March about “potential misconduct” in a paper published earlier that year in one of its journals—Journal of Physics D: Applied Physics. The IOP official Simon Davies explained: Continue reading Five retractions for engineering duo in South Korea over duplication, fraudulent data

How many scientists admit to questionable research practices?

Franca Agnoli

Sure, everyone knows it’s not a good idea to falsify data. But what about somewhat lesser offenses that also undermine the reproducibility of your findings, such as only publishing studies that “work,” and reporting an unexpected finding as something you had predicted from the beginning? In 2012, a survey of more than 2,000 psychologists based in the U.S. found that most admitted to adopting at least one “questionable research practice.” But would psychologists in other countries say the same? (Answer: Yes.) A group of researchers led by Franca Agnoli at the University of Padova posed this question to 277 Italian psychologists; their results appear in PLOS ONE. 

Retraction Watch: Why is it important to compare how many researchers engage in questionable practices in different countries?

Group whose findings support video game-violence link loses another paper

Last July, Joseph Hilgard, a postdoctoral fellow at the Annenberg Public Policy Center at the University of Pennsylvania, saw an article in Gifted Child Quarterly that made him do a double take. Hilgard, who is studying the effects of violent media on aggressive behavior, said the results of the 2016 paper “caused me some alarm.”

The research—led by corresponding author Brad J. Bushman, a professor of communication and psychology at The Ohio State University (OSU)—showed that gifted and non-gifted children’s verbal skills dropped substantially after watching 12 minutes of a violent cartoon. The violent program had a greater impact on the gifted children, temporarily eliminating the pre-video verbal edge they displayed over their non-gifted peers.

To Hilgard, the results suggested that violent media can actually impair learning and performance. But the effect size was huge — so big, Hilgard thought it had to be a mistake. This, plus other questions, prompted Hilgard to contact the authors and the journal. Unfortunately, once he got a look at the data — collected by a co-author in Turkey who became unreachable after the recent coup attempt — the questions didn’t go away. So the journal decided to retract the paper.

Bushman’s body of work has continually supported the idea that violent media increases aggressive behavior, including a controversial 2012 study “Boom, Headshot!” that was retracted earlier this year.

What first struck Hilgard as odd about the 2016 paper was how large the effect of the violent cartoon was: Continue reading Group whose findings support video game-violence link loses another paper

Author duplicated a figure in three papers; two get retracted

Two journals have retracted two papers by the same group within months of each other, after editors were independently tipped off that they contained duplicated figures representing different experiments.

The two papers were published by PLOS ONE and The Egyptian Journal of Biochemistry and Molecular Biology (EJBMB) in 2015 and 2014, respectively. According to the PLOS ONE paper’s corresponding author, last author Saad A. Noeman from Tanta University in Egypt used the same Figure 1 in both papers, along with another 2013 paper in EJBMB.

Corresponding author Yasser S. El-Sayed, head of the Department of Forensic Medicine and Toxicology at Damanhour University in Egypt, told us he learned of this issue after a reader brought the figure manipulation and duplication concerns to PLOS ONE’s attention.

El-Sayed said that he tried to figure out what had happened.

Research misconduct finding — which university won’t discuss — leads to second retraction for prominent physicist

A rising star in nanotechnology, Dmitri Lapotko, has received his second retraction within a month over “a finding of research misconduct” that the university will apparently only disclose on a need-to-know basis.

According to the notice, the journal’s editor and publisher issued the retraction after Lapotko’s former institution—Rice University in Houston—notified them of research misconduct and cited figure duplication issues, which meant the results “should not be relied upon and may be scientifically unsound.”

We recently covered the Belarusian physicist’s first retraction in the journal Theranostics, in which an official at Rice would not confirm a misconduct inquiry, telling us that, “Rice University’s investigations of research misconduct are confidential.”

This time, however, the retraction notice explicitly states that a Rice University research integrity officer reported research misconduct to the journal Applied Physics Letters (APL). We contacted the official, B.J. Almond, who still stuck to the original script: Continue reading Research misconduct finding — which university won’t discuss — leads to second retraction for prominent physicist
