the "academician attacked some tutors for fame and praise", which has caused extensive attention and discussion. Some of the tutors feel "wronged". "Now, it is common for a teacher to be signed as a" signboard ". Professor Lin, a professor of higher education in Shanghai's famous university, should "be named" for his tutor. He told reporters that some colleges and universities have regulations. Students have to publish 1-2 papers in the core journals to graduate. Now, the competition is very fierce, and some students have not even published a paper for two years. Professor Lin admitted that student signatures usually put the tutor on the second author, and he was the first author. "But as a matter of fact, the name of the tutor does not appear in the form of the first author and has no practical benefits for himself, because the title of the title is only seen by the author of the first author. "Being signed" takes a lot of risk. " Professor Lin said, especially now, "check" is very difficult. If there is something wrong with the paper, its reputation will also be destroyed.
