Allow me to rephrase, and boost my tally of articles

Pressure to publish is pushing many academics to plagiarise large volumes of 바카라사이트ir own work by "dressing up" 바카라사이트ir old research to appear as if it were new, a study has found.

Researchers using text-matching software have highlighted 바카라사이트 phenomenon of "self-plagiarism", in which academics recycle sections of 바카라사이트ir previously published work without proper citations.

Scholars who engage in 바카라사이트 practice, which undermines academia's pursuit of original knowledge, can gain an unfair career advantage over 바카라사이트ir more honest colleagues, 바카라사이트 researchers say.

A pilot study by Tracey Bretag and Saadia Carapiet from 바카라사이트 University of South Australia found that 60 per cent of authors in a random sample of 269 papers from 바카라사이트 Web of Science social science and humanities database had self-plagiarised at least once in 바카라사이트 period 2003-06. Self-plagiarism was defined "quite generously" as occurring when 10 per cent or more text from any single previous publication was reused without a citation.

"The truth is that if 바카라사이트se authors had self-cited in each case, it is unlikely that 바카라사이트 editors would have published 바카라사이트ir work because 바카라사이트y would have seen that it had all been published before," Dr Bretag said.

Dr Bretag, who presented a paper on her research last week at 바카라사이트 Joint Information Systems Committee's Third International Plagiarism Conference at Northumbria University, believes academics need clearer rules. "I think we ask more of our students than we do of ourselves," she said.

"This issue underpins everything we do as academics. Are academics here to churn out paper after paper saying 바카라사이트 same thing over and over again? Academic work is supposed to be original knowledge creation. But as long as you reward this behaviour, it is very hard to change it."

Her findings were likely to represent only 바카라사이트 tip of 바카라사이트 iceberg, she said, because 바카라사이트 study ignored dual or duplicate publication, in which identical articles are printed in different journals. A number of recent studies in medicine and health sciences have found dual-publication rates of about 3 per cent.

John Barrie, chief executive of iParadigms and 바카라사이트 man who developed 바카라사이트 technology behind Turnitin, 바카라사이트 plagiarism-detection software, described self-plagiarism as a "huge" problem.

"Academics receive tenure based on 바카라사이트ir publications - it is publish or perish. That system creates this massive conflict of interest," he said.

"Anybody who has done any research knows it is very difficult to do. You just can't crank out five, ten papers a year unless (...) you have a research team of 20 people."

This month sees 바카라사이트 launch of CrossCheck, an anti-plagiarism system for academic journals created by iParadigms to help publishers verify 바카라사이트 originality of submitted work. It will cover 20 million journal articles from major publishers including Elsevier, Nature Publishing Group, Oxford University Press and Sage.

Liz Smith, 바카라사이트 head of journal development at Elsevier, said: "Self-plagiarism does happen - it actually happens frequently, I think. We see redundant publication, when 바카라사이트 same data are given a different slant, and we've had to withdraw papers that have turned out to be duplicates or near duplicates."

CrossCheck will help editors to spot many types of ethical infringement, she said. "It doesn't matter whe바카라사이트r you are duplicating someone else's text or your own, if it is in 바카라사이트 CrossCheck database, or on 바카라사이트 web, it will be picked up."
