This is very important to me and other young researchers. The confusion about the importance of authorship in a paper is high because recently, I have come to understand that it depends on the academic institution, the publishing journal or even the discipline. I would like to have this confusion cleared. Is the order of importance of authors in a published paper dependent on the country, university, journal or discipline?
Is the last author more important than the second author in a paper?
How important is the second author?
