Cancer org bestows award on scientist under investigation

Carlo Croce

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:

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 that was retracted earlier this year.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

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

“Strange. Very strange:” Retracted nutrition study reappears in new journal

In an unusual turn of events, a nutrition paper has come back to life a year after being pulled from its original publication.

After the paper was retracted from the journal Obesity, the authors revised it and republished it in another journal, Pediatric Obesity. Both journals are published by Wiley. The second version of the paper doesn’t mention the previous retraction. Indeed, the journal editor told us he didn’t know the paper had been retracted. Still, he stood by his decision to publish it.

The authors told us the paper was retracted after editors at Obesity raised concerns over the authors’ methodology. The authors revised the paper, adding some analysis and explanation of their methodological approach, and said the new version was accepted by peer reviewers before being published in Pediatric Obesity.

However, an outside expert who reviewed both papers for us said he thinks the authors didn’t change enough. According to Patrick McKnight, head of the Measurement, Research methodology, Evaluation, and Statistics group at George Mason University and a Statistical Advisory Board member of STATS.org:

Authors who retract for honest error say they aren’t penalized as a result

Daniele Fanelli

Are there two types of retractions? One that results from a form of misconduct, such as plagiarism or manipulating figures, and another that results from “honest errors,” or genuine mistakes the authors have owned up to? More and more research is suggesting that the community views each type very differently, and don’t shun researchers who make mistakes and try to correct the record. In yet another piece of evidence, Daniele Fanelli and his colleagues recently published the results of their interviews with 14 scientists who retracted papers for honest errors between 2010-2015. Although much of what scientists said affirmed what Fanelli – based at METRICS (the Meta-Research Innovation Center) at Stanford University – has long argued about retractions due to honest error, some of their answers surprised him.

Retraction Watch: We’ve seen the community reward scientists who retract papers for honest error, including a 2013 paper that showed no citation penalty for researchers who self-retract. Yet the interviewees said they were surprised to realize there weren’t any negative consequences to their self-retractions (some even got kudos for doing it). Why do you think people don’t realize how the community will view honest error?

What leads to bias in the scientific literature? New study tries to answer

By now, most of our readers are aware that some fields of science have a reproducibility problem. Part of the problem, some argue, is the publishing community’s bias toward dramatic findings — namely, studies that show something has an effect on something else are more likely to be published than studies that don’t.

Many have argued that scientists publish such data because that’s what is rewarded — by journals and, indirectly, by funders and employers, who judge a scientist based on his or her publication record. But a new meta-analysis in PNAS is saying it’s a bit more complicated than that.

In a paper released today, researchers led by Daniele Fanelli and John Ioannidis — both at Stanford University — suggest that the so-called “pressure-to-publish” does not appear to bias studies toward larger so-called “effect sizes.” Instead, the researchers argue that other factors were a bigger source of bias than the pressure-to-publish, namely the use of small sample sizes (which could contain a skewed sample that shows stronger effects), and relegating studies with smaller effects to the “gray literature,” such as conference proceedings, PhD theses, and other less publicized formats.

However, Ferric Fang of the University of Washington — who did not participate in the study — approached the findings with some caution:

Scientist who sued university earns two more retractions, bringing total to five

A scientist who sued his employer for millions of dollars has earned two more retractions, for papers that had already been flagged by the journal.

By our count, Rakesh Kumar now has five retractions and multiple corrections.

Kumar sued his employer, George Washington University, for $8 million, alleging emotional distress when they put him on leave from his position as department chair following a finding of misconduct. That suit was settled last year, for undisclosed terms.

The two newest retractions in the Journal of Biological Chemistry — which tagged the papers with Expressions of Concern last year — both state that, according to Kumar, the problematic figures were assembled by “specific co-authors” — unnamed — in his lab. Here’s the first notice:

Neuroscientist Stanley Rapoport hasn’t had much luck with his co-authors.

Recently, we’ve reported on multiple retractions of papers co-authored by Rapoport after three different first authors were found to have committed misconduct. Now, the fallout from one of those cases had led to four more retractions, bringing Rapoport’s total to 12.

The latest batch of retractions stem from the actions of Jagadeesh Rao.

Here’s the first notice, issued by Psychopharmacology:

After lawsuit threat, journal forces author to heavily revise education paper

Under threat of a lawsuit, an education journal changed its mind about publishing a paper that it had already accepted after peer review.

Last summer, Education Policy Analysis Archives, published by the Mary Lou Fulton Teachers College at Arizona State University, informed San Francisco State University professor Stanley Pogrow that the journal would be publishing his paper criticizing a widely used reform intervention for schools in poor districts called Success For All.

According to Success For All‘s website, the program is currently used in more than 1,000 schools in 48 states and received just over $10.5 million in grant funding in 2015. In 2010, the program was one of four recipients of the U.S. Department of Education’s $50 million Investing in Innovation Scale‑up grant.

Yet when Success For All’s co-developer, Robert Slavin at Johns Hopkins University, read a pre-publication draft of the paper, he threatened the journal with legal action if they published it. According to Slavin, the manuscript contained “libelous” and “defamatory” statements.

Subsequently, ASU declined to publish the accepted paper, and instead told Pogrow they would only publish a revised piece on the methodology used to evaluate which school interventions are effective — and thus should receive public funds. The revised paper does not directly mention Success For All or Slavin in the text (although it cites past articles by Pogrow criticizing the program). The revision, which Pogrow agreed to, “gutted the article,” he told us.  Continue reading After lawsuit threat, journal forces author to heavily revise education paper

Another correction for prominent cancer researcher who’s dodged accusations for decades

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.
