Fredrickson-Losada “positivity ratio” paper partially withdrawn

In 2005, Barbara Fredrickson and Marcial Losada published a paper in American Psychologist making a bold and specific claim:

…the authors predict that a ratio of positive to negative affect at or above 2.9 will characterize individuals in flourishing mental health.

The paper made quite a splash. It has been cited 360 times, according to Thomson Scientific’s Web of Knowledge, and formed the basis of a 2009 book by Fredrickson, Positivity: Top-Notch Research Reveals the 3 to 1 Ratio That Will Change Your Life.

But something didn’t sit right with Nick Brown, a psychology grad student at the University of East London. He found the paper’s claims wanting, and contacted Alan Sokal — yes, that Alan Sokal, who published a fake paper in Social Text in 1996. Sokal agreed, and he, Brown, and Harris Friedman published a critique of the paper in July of this year in American Psychologist. Its abstract: Continue reading Fredrickson-Losada “positivity ratio” paper partially withdrawn

That’ll do it: Physics paper retracted for a “pattern that is unphysical”

Last December, we brought you the story of a math paper that was retracted because it made “no sense mathematically.” Today, we have that retraction’s cousin: A physics paper retracted because some of the data are “unphysical.”

Here’s the notice for “Room temperature ferromagnetism in pure and Co- and Fe-doped CeO₂ dilute magnetic oxide: effect of oxygen vacancies and cation valence,” which was published in April 2011 in the Journal of Physics D: Applied Physics: Continue reading That’ll do it: Physics paper retracted for a “pattern that is unphysical”

Retraction for iffy data as authors of chicken enzyme paper lay an egg

The authors of an article in the International Journal of Biological Macromolecules have pulled the paper in what appears to be an authorship dispute sparked by premature submission.

The paper, “Renaturation and one step purification of the chicken GIIA secreted phospholipase A2 from inclusion bodies,” came from a group of researchers in Tunisia and Marseille, France, and was published online last May. It has yet to be cited, according to Thomson Scientific’s Web of Knowledge. As the abstract states:

A Cancer Cell mega-correction for highly cited researcher who retracted paper earlier this year

MIT’s Robert Weinberg, a leading cancer researcher who retracted a Cancer Cell paper earlier this year for “inappropriate presentation” of figures, has corrected a different paper in the same journal.

Here’s the correction for “Species- and Cell Type-Specific Requirements for Cellular Transformation:”

We were apprised recently of errors made in the assembly of Figures 2B, 3A, 4A, 4B, and 5G, resulting in the incorporation of incorrect representative images in these figures. These errors occurred during the electronic assembly and have no bearing on the conclusions of the study. The corrected figures are shown below. The authors apologize for any possible confusion this might have caused.

Here’s the original Figure 2 and caption, followed by the new version (read all the way to the end of the post for more details on how this came to light): Continue reading A Cancer Cell mega-correction for highly cited researcher who retracted paper earlier this year

Image highjinx lead to retraction of hot pepper paper

You might be forgiven for thinking that the editors were describing a bad relationship rather than a paper gone wrong, the journal of Plant and Cell Physiology is retracting a 2004 article by Korean researchers who “manipulated and repeatedly used” micrographs.

The article, “Ornithine Decarboxylase Gene (CaODC1) is Specifically Induced during TMV-mediated but Salicylate-independent Resistant Response in Hot Pepper,” which appeared a s a short communication in the journal, came from the lab of Kyung-Hee Paek at Korea University.

According to the retraction notice: Continue reading Image highjinx lead to retraction of hot pepper paper

The one that got away: Plagiarism cuts line on fish stock paper

A pair of researchers in India has lost a paper in Reviews in Fish Biology and Fisheries for lifting chunks of text from other sources.

The article, “Advancements in morphometric differentiation: a review on stock identification among fish populations,” appeared in last March from scientists at the National Bureau of Fish Genetic Resources in Lucknow.

According to the retraction notice: Continue reading The one that got away: Plagiarism cuts line on fish stock paper

Paper on over-the-counter drugs goes over the line in borrowing text

The journal Clinical Research and Regulatory Affairs has retracted a 2012 article on over-the-counter drugs by a trio of pharmacy researchers in India who decided to “reproduce content to a high degree of similarity” from other sources.

Here’s how the retraction notice puts it: Continue reading Paper on over-the-counter drugs goes over the line in borrowing text

Lancet retracts Jikei Heart Study of valsartan following investigation

The Lancet has retracted a study of Novartis’ blood pressure drug valsartan (Diovan) that has been subject to an investigation following the retraction of a related study earlier this year.

When two words colloid: “copied and manipulated” figures prompt retraction of nanoparticle paper

The journal Colloids and Surfaces B: Biointerfaces has retracted a 2011 paper by a group of researchers in India who misappropriated — and then manhandled — a pair of images from a previously published article by other scientists.

The paper, “Synthesis and characterization of chitosan and grape polyphenols stabilized palladium nanoparticles and their antibacterial activity,” was written by authors from various institutions in Tamil Nadu, and appeared online in December 2011 and in print the following April. It has been cited three times, according to Thomson Scientific’s Web of Knowledge.

Here’s the abstract: Continue reading When two words colloid: “copied and manipulated” figures prompt retraction of nanoparticle paper
