Recursive plagiarism? Researchers may have published a duplicate of a study retracted for plagiarism

with 15 comments

acta physica sinicaSometimes plagiarism, like an onion, has layers.

That appears to be the case in a paper brought to our attention by sharp-eyed reader Vladimir Baulin, whose work was copied in a 2006 paper that Journal of Biological Physics retracted for plagiarism.

But you can’t keep a good thief down: the plagiarizing authors just popped up in a new journal with a Chinese-language version of their retracted paper, that looks an awful lot like a knock-off. Here’s a note from Baulin: Read the rest of this entry »

with 92 comments

nijkampRetractions have arrived in the case of Peter Nijkamp, a leading Dutch economist accused of duplication and plagiarism. The Review of Economic Analysis has removed two of Nijkamp’s articles for self-plagiarism.

The article, “Arsenic Sulfide Promotes Apoptosis in Retinoid Acid Resistant Human Acute Promyelocytic Leukemic NB4-R1 Cells through Downregulation of SET Protein,” came from a group in the Department of Hematology at the First Affiliated Hospital at Xi’an Jiaotong University, and was led by Yuwang Tian, a pathologist at the General Hospital of Beijing Military Area of PLA.

Or at least that’s what the manuscript eventually said. According to the expression of concern, however, that’s not what it said initially: Read the rest of this entry »
