has anyone Idea about "inner kitchen" in science to compare activity of scientists in Europe and USA? In Germany for example there are some professors who did not publish one or two years at all and than they publish in very good journal like science or nature, in USA I have feeling professors try to publish in good journal but I find rare case when somebody did not publish in year at all, they would be (I mean generally and my feeling, please notice your Idea if I am wrong) publish in journals like 7-15 impact factor but for example 3 papers. I think this should be come from system, f.e. if somebody has guaranteed position and money for 10 years than for him would be important to publish in this time and be ready till end of this time to get new position so in idea they can not publish 3 years and major is what they have at 9th years (of course if they dont want get additional funding in this time), but if somebody has funding for short time than to get additionally finding he would be try to get at least some papers in one or two years. So where fill better professor in biological sciences in USA or Europe and how you explain? and generally what is better to have one publication in journal with impact factor f.e. 30 or have 3 publications in journal with i.f. 10?
