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: Read the rest of this entry »
This month hasn’t been all bad for Carlo Croce. Despite issuing two corrections and being the subject of a lengthy New York Times article about how he’s dodged misconduct accusations for years (prompting his institution to re-open an investigation), Croce is now the recipient of a prestigious award from the American Association for Cancer Research.
In a recent news release, the AACR announced it was bestowing Croce the 11th Margaret Foti Award for Leadership and Extraordinary Achievements in Cancer Research, named after the CEO of the AACR, for his work in the field.
According to the news release:
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: Read the rest of this entry »
The chair of a biology department who has faced years of misconduct accusations has taken another hit—a lengthy correction due to text “overlap” between one of his PNAS papers and six other articles.
According to the correction, a reader contacted the journal to notify the editors that text and sentences in multiple sections of the 2015 paper — on which Carlo Croce is last author — were lifted from other sources without quotation marks.
This is the second correction for Croce in PNAS regarding overlap issues in just the last few weeks—the first was published on March 7 (see here). In both instances, PNAS did not call the textual similarities plagiarism, but the notice details multiple instances of overlap.
Croce, the chair of the department of cancer biology and genetics at The Ohio State University (OSU), is no stranger to controversy.
Today isn’t a great day for Carlo Croce, chair of the department of cancer biology and genetics at The Ohio State University (OSU).
The New York Times has a lengthy article detailing the misconduct accusations that have swirled around Croce for years. We’ve covered many, but The Gray Lady obtained documents that show there have been many more.
The story mentions a 2013 letter from Ohio State University to pseudonymous whistleblower Clare Francis (which we reported on in 2014), acknowledging Francis’s allegations against Croce. However, in the letter, an administrator said OSU saw no reason to investigate Croce.
The story didn’t stop there, as the Times reports:
Researchers have retracted a biology paper that included an image mismatch — despite the fact that, as they claim, another image in the same paper confirms the original findings.
The authors say they plan to resubmit the paper with the corrected figure panel.
The second to last author — Carlo Croce, chair of the department of cancer biology and genetics at The Ohio State University — told us he believes there’s more to the retraction than what the notice says. Specifically, he said that the paper includes an image from a previous paper by the same authors, which he called “fraud.”
Here’s the latest retraction notice, published in Cell Death and Differentiation:
A cancer biologist has retracted a 2016 News & Views article in a Nature journal, alleging that the journal tried to censor his writing by asking him to remove passages that criticized another journal (Cell).
Carlo Croce, the sole author of the article in Nature Reviews Clinical Oncology from Ohio State University in Columbus, described the journal’s actions to us as “disgusting” and “worrisome.”
A spokesperson from the journal sent us this statement:
We regret that this situation occurred. We cannot comment beyond the retraction notice.
This isn’t Croce’s first retraction (we just found another recent one, in the Journal of Biological Chemistry, over image problems). He’s also co-authored multiple papers with Alfredo Fusco, a cancer researcher in Italy who has nine retractions under his belt, and is undergoing criminal investigation for scientific misconduct.
Here’s the retraction notice, published in Nature Reviews Clinical Oncology on October 4: Read the rest of this entry »
Consider this: Fragments of a PLOS ONE paper overlap with pieces of other publications. The authors used them without credit and without quotation marks.
This sounds an awful lot like plagiarism — using PLOS‘s own standards, even. But the journal isn’t calling it plagiarism. They’ve labeled this an instance of “text overlap,” a spokesperson told us, based on the amount of material that the paper shares with others.
The last author — Carlo Croce, who has two retractions under his belt — denies that he plagiarized, and says that his university has cleared him of a plagiarism charge from an anonymous whistleblower.
PLOS fixed this case last year with a correction notice — not the common course of action for a case of confirmed plagiarism. Take a look at the notice for yourself:
