Why traditional statistics are often “counterproductive to research the human sciences”

Andrew Gelman

Doing research is hard. Getting statistically significant results is hard. Making sure the results you obtain reflect reality is even harder. In this week’s Science, Eric Loken at the University of Connecticut and Andrew Gelman at Columbia University debunk some common myths about the use of statistics in research — and argue that, in many cases, the use of traditional statistics does more harm than good in human sciences research. 

Retraction Watch: Your article focuses on the “noise” that’s present in research studies. What is “noise” and how is it created during an experiment?

Elsevier to retract six more papers by computer scientist, citing duplication and fake reviews

Yesterday we reported that Elsevier journals had pulled three papers by a computer scientist with an impressive publication record. The publisher has since informed us that it plans to pull six more, again citing duplication and manipulation of the peer-review process.

Shahaboddin Shamshirband at the University of Malaya in Kuala Lumpur, Malaysia’s record will be down by a total of nine papers once the publisher issues the additional notices. We also found evidence that an additional paper was removed by a journal, but haven’t confirmed if that’s a retraction.

One of Shamshirband’s co-authors has objected to one of the retractions Elsevier has already issued for faked reviews, arguing the reviewers were PhD students without institutional email addresses. A spokesperson for Elsevier told us:

Students withdraw report of private stem cell retreat

Master’s students have retracted a review of an internal meeting of stem cell researchers because it contained confidential information.

According to the Managing Director of the society, Stem Cell Network North Rhine Westphalia (NRW), the event was not open to the public, and the authors had not contacted either the society or the scientists they cited before publishing the report.

Here’s the retraction notice for “A Report on the Internal Retreat Meeting of the Stem Cell Network North Rhine Westphalia,” published online in Molecular Biotechnology on October 31 and retracted shortly after on December 14: Continue reading Students withdraw report of private stem cell retreat

Computer scientist loses at least three papers, two for faked reviews

A computer scientist in Malaysia has lost two papers for faked peer reviews, and another for duplication. A fourth paper on which he is a co-author appears to have simply disappeared.

One retraction lays the blame for the fake reviewer on corresponding author Shahaboddin Shamshirband at the University of Malaya in Kuala Lumpur, Malaysia. According to the journal, Shamshirband — who has co-authored more than 200 papers and book chapters, despite receiving his PhD in 2014, according to his biography on Vitae — supplied a fake email for the reviewer during the submission process.

Here’s the retraction notice for that paper, issued by the journal Measurement:

Authors contest retractions for “high degrees of similarity” with previous papers

A group of researchers has lost two papers due to “high degrees of similarity with previously published works,” according to the notices.

The authors are objecting to the retractions, however, arguing the journal never gave them an opportunity to show their work is different from the previous papers.

Both papers were published in the International Journal of Plastics Technology, and share the same three authors, all based at Charan Singh University in India. They were retracted by the Editor in Chief, according to the notices.

“Effect of dynamic cross-linking on melt rheological properties of isotactic polypropylene (iPP)/ethylene–propylene diene rubber (EPDM)/nitrile rubber (NBR) elastomeric blends” was published in 2011. Here’s the retraction notice:

Study about words’ effect on mood to be retracted after investigation finds evidence of data manipulation

A study examining whether the verb tense you use to describe a positive or negative experience influences your current mood will be retracted after a university investigation found the data had been manipulated.

By whom is the question — the notice cites an unnamed graduate student as the source of the manipulation, and says the only author, William Hart, was unaware of what had occurred.

We spoke with Hart, based at the University of Alabama, who declined to identify the student, nor say whether he or she was still working at the university. He did say the experience has been trying:

Cancer researcher logs 6 retractions, bringing total to 10

Anil Jaiswal

A journal has retracted six papers by a cancer researcher at the University of Maryland in Baltimore, bringing his total to 10.

The retractions cite an investigation by the university, and detail problems ranging from duplicated images, to tweaking an image to conceal particular bands, to including unreliable data.

Three of the papers had already been flagged by the journal with expressions of concern. The last author on all the papers is Anil Jaiswal, a professor in the pharmacology department. He has issued four previous retractions.

Bruce Jarrell, the Chief Academic and Research Officer and Senior Vice President at the University of Maryland, told us at least two more retractions are forthcoming:

Whistleblower gets court backing in defamation case — but at a cost

It’s been a long and winding road for a whistleblower at Indiana University, South Bend.

After Mark Fox, a professor of management and entrepreneurship accused two business professors of plagiarism in 2012, a university investigation found one of the two men — Douglas Agbetsiafa, the former chair of the economics department — guilty of plagiarism, and terminated him in January 2014. The other professor was cleared of any wrongdoing — then sued Fox for defamation in June, 2014.

Fox won the case, but it dragged on. More than two years later, in December 2016, the Indiana Supreme Court declined to hear an appeal.

Fox told us:

Researchers submit two similar papers 8 days apart; one is retracted

After a research group submitted two similar papers only days apart to different journals, one journal has retracted the paper — and told the other it should do the same.

The papers, by a group of authors based in Romania, describe a new polymer to stop the formation of biofilms. After a reader flagged the papers — which were submitted within eight days of each other in September, 2015 — as being similar, a journal has retracted one, and recommended the other journal retract the second. Although the second journal told us it planned to flag the paper with a notice alerting readers to the duplication, the notice has not yet appeared online.

The journal that issued the retraction — the International Journal of Polymer Analysis and Characterization (IJPAC) — called it a “a clear case of self-plagiarism,” according to the notice:

Columbia University probe prompts retraction of cardiovascular paper

A journal has retracted a 2011 study at the request of Columbia University.

According to Jeanine D’Armiento, the study’s last author, the newly retracted paper in Clinical Science contained a figure from a Journal of Hypertension paper published by the same authors earlier that year. 

First and corresponding author Joseph George told Retraction Watch the error was unintentional. A Columbia spokesperson sent us this statement: Continue reading Columbia University probe prompts retraction of cardiovascular paper
