Last week, we wrote about a somewhat remarkable retraction, of a 15-year-old paper by a current Illinois senator who used to be a mathematician. At the time, we were a bit perplexed by the language of the notice, which the senator — who helpfully took our call — couldn’t answer, since he wasn’t involved in drafting the notice.
We’ve since heard back from the journal that retracted the paper, which explained that their phrase that “most results are false” meant the findings by state senator Daniel Biss were inaccurate — not fraudulent.
Here’s more explanation from a joint statement sent to us by Jan van Mill and Jerry Vaughan, the editors in chief of Topology and its Applications:
Here’s something you don’t see every day: A state senator with an academic publication record, in his former career as a mathematician. Even more unusual: A retraction of one of his 15-year-old papers, after the journal realized most of the results were incorrect.
According to the notice, some aspects of the paper by Daniel Biss — now a democratic Illinois State Senator — are also “ambiguous.”
We spoke with Senator Biss, who told us he had been contacted by an editor who told him someone had raised questions about the paper, but he didn’t have much input in the notice:
According to the retraction notice in Intelligent Automation & Soft Computing, the authors didn’t cite or acknowledge the other study in the Turkish Journal of Electrical Engineering & Computer Science.
First author of both papers, Şeref Sağıroğlu, who is based at Gazi University in Ankara, Turkey told Retraction Watch that he doesn’t believe the two papers have significant overlap. Still, the research is related, so when he learned the retracted paper didn’t reference the previous one:
The retraction notice for “Goodness-of-fit tests for a proportional odds model,” which appears in the Journal of the Korean Data and Information Science Society, cites an investigation by an academic ethics committee, but it’s unclear where this review panel was based.
A researcher in Egypt is threatening to sue a mathematics journal if it doesn’t un-retract one of his papers.
The American Journal of Computational Mathematics in May retracted Mostafa M. A. Khater‘s 2015 paper, “The Modified Simple Equation Method and Its Applications in Mathematical Physics and Biology.” The retraction notice is sparse on the details, indicating only that the article was not up to snuff: Read the rest of this entry »
With so many retraction notices pouring in, from time to time we compile a handful of straight-forward retractions.
Once again, this list focuses on duplications — but unlike other duplications, these authors were not at fault. Rather, these retractions occurred because the publishers mistakenly published the same paper twice — the result of a transfer between publishers, for instance, or accidentally publishing the unedited version of the paper. We’re forced to wonder, as we have before, whether saddling researchers’ CVs with a retraction is really the most fair way to handle these cases.
So without further ado, here’s five cases where the journal mistakenly duplicated a paper, and had to retract one version: Read the rest of this entry »
According to the first author of the paper — Hafsa Athar Jafree from the University of Karachi in Pakistan — none of the authors agreed to the EOC notice. She told us the paper contains a few typos, which may have made it unclear to some readers, but said the authors had provided all of the necessary information to “justify the presented algorithms.”
A PLOS ONE spokesperson told us the journal decided to issue an EOC after consulting the editorial board, which raised significant concerns about the study.
In 2014, the journal issued a correction to the study to fix several equations in the original article.
In this case, it’s easy to see how editors were duped (as it were). Both journals received the papers within a few months of each other, and then published them in quick succession; both have since been retracted. The papers share a first author, Jin Li, affiliated with Jiujiang University in China.
How similar are Li’s papers? See for yourself.
Here’s the abstract for “Landesman-Lazer type condition for second-order differential equations at resonance with impulsive effects,” received by Advances in Difference Equations in June 2014 and published in September 2014: Read the rest of this entry »
A paper has been retracted from Semigroup Forum because it includes material taken from another researcher’s manuscript — which was handwritten. In fact, the same journal had already published a paper by the plagiarized researcher, also based on the same manuscript. The journal editor told us that, although the two papers are similar, they are not word-for-word copies, and thus escaped detection.
