In a confirmation of what I previously wrote about predatory authors:
[R]esearch grants and promotions are awarded on the basis of the number of articles published, not on the quality of the original research.
This has fostered an industry of plagiarism, invented research and fake journals that Wuhan University estimated in 2009 was worth $150m, a fivefold increase on just two years earlier
