Blatant plagiarism sinks paper (and earns a sabbatical!) for mathematician

You know it’s a good one when it makes it onto the Wikipedia page for “scientific misconduct.”

On April 21, the International Journal of Pure and Applied Mathematics retracted two 2008 papers by scientist Alexander Spivak of Holon Institute of Technology in Israel. In September, the journal updated the notice to explain why: The papers both contained copy/pasted chunks from a 2001 paper by Spivak’s post-doc boss at Tel Aviv University, Zeev Schuss, and two other authors.

The tipster seems to have been Schuss himself, who told us about his role in the unravelling of the fraud: Continue reading Blatant plagiarism sinks paper (and earns a sabbatical!) for mathematician

Humbert, Humbert: Duplication topples matrix function paper

jemsA pair of mathematicians from Egypt has lost their 2012 article in the Journal of the Egyptian Mathematical Society because they reused some of the material from a previous publication.

The article, with the Nabokovian title, “On Humbert matrix functions,” was written by A. Shehata and  M. Abul-Dahab. According to the introduction: Continue reading Humbert, Humbert: Duplication topples matrix function paper

Nine-year-old plagiarism allegation leads to retraction of math paper

entropyIt is often said that science is self-correcting, but it is usually more accurate to add “in the long run” to that statement.

Take, for example, this retraction of a 10-year-old paper in Entropy that had been questioned since 2005. Here’s the notice for “Statistical Convergent Topological Sequence Entropy Maps of the Circle:”

The editors were made aware that a paper published in Entropy in 2004 [1] may have plagiarized an earlier paper by Roman Hric published in 2000 [2]. After checking with specialized plagiarism software, we found that this claim is indeed correct and almost the entire paper is a verbatim copy of the earlier one. After confirmation of this fact, the editors of Entropy have decided to retract the paper immediately.

We would like to apologize to the readers of the journal that it took so many years to notice this error and to retract the paper. Apparently there is a comment on MathSciNet (http://www.ams.org/mathscinet/) since 2005 that points out this case of possible plagiarism [3], however the editorial office was not aware of this until recently. We request readers of the journal to directly get in touch with the editorial office and the editors of the journal for similar cases in the future, so that they can be handled promptly.

Remedial math lesson: When does one reference equal an entire paper?

ImageA higher-ed journal has retracted a recent paper by a New Jersey scholar who failed to adequately cite one of her sources.

Trouble is, the researcher did reference the article more than once — raising the question of whether a retraction, rather than a correction, was the right move.

The paper was written by Lynne Kowski, a professor of mathematics at Raritan Valley Community College in New Jersey,  and it appeared online in November 2013 in the Community College Journal of Research and Practice.

Here’s the abstract of the article, “Mathematics Remediation’s Connection to Community College Success:” Continue reading Remedial math lesson: When does one reference equal an entire paper?

Neural Networks retracts rerun

neuralnetworksIrony alert: If you’re going to write articles about recurrent neural networks, make sure they don’t, well, recur.

The journal Neural Networks has retracted a 2012 paper by a group of researchers from Spain for publishing what amounted to a repeat of a 2011 article in a different but closely related journal. Scientific publishing, alas, is not like Hollywood, where remakes of movies and TV shows is not only acceptable, it seems to be the only flavor producers are willing to taste.

The article was titled “Hopf Bifurcation Stability in Hopfield Neural Networks” — Hopf, for those keeping score at home, is Eberhard Hopf, a famous (and politically controversial) mathematician and founder of something called ergodic theory — and it came from scientists at the University of La Laguna, in the Canary Islands.

According to the notice: Continue reading Neural Networks retracts rerun

Double submission leads to retraction of probability paper — and a publishing ban

jtbWhat are the chances of successfully duplicating publication in the Journal of Theoretical Probability? Not too high, it seems.

A pair of South Korean authors have gotten a five-year ban from the journal for double-publishing a paper in the math literature.

The article, “Convergence of Weighted Sums for Arrays of Negatively Dependent Random Variables and Its Applications,” was written by Jong-Il Baek and Sung-Tae Park of Wonkwang University in IkSan.

According to the retraction notice: Continue reading Double submission leads to retraction of probability paper — and a publishing ban
