Paper on circulating tumor cells taken out of circulation after lab error

medical oncologyA group of researchers at the Guangdong Academy of Medical Sciences in Guangzhou, China have retracted a paper that came out of a clinical trial on transarterial chemoembolization, a targeted kind of chemotherapy.

According to the notice, one of the authors mixed up the control samples with the clinical samples, and “could not recall which samples were in the wrong group.” The paper hasn’t yet been cited, according to Thomson Scientific’s Web of Knowledge.

The Leadership Quarterly has retracted a trio of papers by Frederick Walumbwa, an “ethical leadership” guru at Florida International University, whose work has come under scrutiny for flawed methodology. And another journal  has pulled one of his articles for similar reasons. That brings his count – as far as we can tell — to seven retractions and a mega-correction.

Meanwhile, Arizona State University, Walumbwa’s former employer, has found

that the preponderance of evidence does not support the charge of research misconduct by Dr. Walumbwa…

but that he engaged in “poor research practice.”

The bottom line, according to the Leadership Quarterly, which first announced problems with the articles in February:

A tale of two notices as Tunisian chemists lose two papers for duplicated data

molecules-logoMolecules has pulled a 2010 article by a trio of chemists from Tunisia who tried — and succeeded, for a while, at least — to publish the same data twice. The article was titled “An Expeditious Synthesis of [1,2]Isoxazolidin-5-ones and [1,2]Oxazin-6-ones from Functional Allyl Bromide Derivatives.” And indeed it was expeditious. Here’s the notice: Continue reading A tale of two notices as Tunisian chemists lose two papers for duplicated data

University of Utah investigation fingers chem engineering grad student for misconduct

acs nanoA second retraction has been issued in a case of research misconduct at the chemistry department of chemical engineering at the University of Utah.

The first retraction, in August of 2013, got a lot of attention for how poorly faked the figures were. At the time, an expression of concern was issued on the paper that has just been retracted.

Today, we exchanged emails with Jeffery Botkin, the research integrity officer at the University of Utah, who ran the investigation into the misconduct. He summarized the report for us below. Continue reading University of Utah investigation fingers chem engineering grad student for misconduct

We spoke to the author of the retracted work, who explained that over the course of ten years of revising his classroom material, he lost track of what was original, and what was written by him or his fellow University of Saskatchewan professors.

Here’s the notice for “Ramm Wholesale: Reviewing Audit Work”: Continue reading “Embarrassing and regrettable incident of faulty memory” leads to retraction
