Academic journals in Russia are retracting more than 800 papers following a probe into unethical publication practices by a commission appointed by the Russian Academy of Sciences (RAS). The moves come in the wake of several other queries suggesting the vast Russian scientific literature is riddled with plagiarism, self-plagiarism, and so-called gift authorship, in which academics become a co-author without having contributed any work.
.....In March 2018, for instance, Dissernet, a network aimed at cleaning up the Russian literature, identified more than 4000 cases of plagiarism and questionable authorship among 150,000 papers in about 1500 journals.
