Many universities around the world strongly recommend their academic staff to publish in international journals with high impact factor rather than writing books! As an old generation academic, I believe that book publications can elaborate more scholarly thoughts and provide more examples. However, due to the limited space for international journal articles (word count: about 4000-6000 English words) and efficient circulation of international journal papers, the details are omitted. For what cogent reasons should we follow or should we reject this recommendation? Is the quality of journal-focused supervision deteriorating? If so, why so? If not so, why not so?
