Heart pulls sodium meta-analysis over duplicated, and now missing, data

University of Virginia doctoral candidate plagiarizes in business ethics journal, but remains in program

We’ve already reported on the retraction of a paper in a business ethics journal for plagiarism. Yes, plagiarism in an ethics journal. But it turns out there’s at least one more case of exactly the same thing, albeit in a different business ethics journal. Here’s the notice from the Journal of Business Ethics:

Pfizer database errors cause two voluminous retractions for JACC statin-biomarker papers

Image problems lead to demise of paper on ginseng for heart attack

A group of researchers from Shangdong, China, has retracted their 2011 paper in the Journal of Molecular Medicine on the heart-protective properties of a substance in ginseng because the article contained dodgy figures.

Oh, the irony: Business ethics journal paper retracted for plagiarism

Is this the new business ethics? In January, we reported on a paper retracted from the Journal of Business Ethics for duplication. That earned the author a five-year publishing ban. This week, we learned of a case of plagiarism in another journal in the field, the Journal of Academic and Business Ethics.
