There are usually some controversies or contentions particularly with whom first author, corresponding author and last author should be. While some institutions only reckon first author for full score during evaluation, other positions are not 'so' countenanced.
This authors positioning becomes major subject of controversies especially when supervisor is not yet a full grade professor. While corresponding author sometimes design the research and provides intellectual supervision, s/he losses some percentage during evaluations for not being the first author based on some institutional disposition.
Is there really a global standard with respect to authors' positioning on manuscript?
