Dear author and everyone, I have to totally disagree with this article. Why only target Phd? Just because its on the top of the academic stages? People from all acedemic stages contribute to the sucess and progress of technology. Hence its important to maintain standars in all levels. Having an expiration date on Phd's is a narrow minded approach because you are not focussing on the core problem. Malpractice or corruption at Phd levels??? Doesnt it exist on all levels? To increase quality of work we should focus on establishing values on a global/general sense rather than a particular sector.
