The importance of PhD research is to conduct original research of significance that promotes the advancement of knowledge. So, I think publication is one of the most important methods in which the conceived knowledge is disseminated for further application. Most curriculum designs for PhD studies in natural sciences literally require the publication of 2 to three on peer-review journals. However, it is not clear how much emphasis is laid down and pressure students to publish. Therefore, I am intereseted to know how much emphasis is given to the importance of publications on peer-reviewed journals by universities. I hope universities collect data on their students who published on peer-reviewed journals. My question is then, what percent of students publish 2 or more before they defend their thesis?
