What can be done to resolve academic authorship disputes?

With respect to the "first author" placement in a published scientific paper, when I had a post-graduate student under my direction working for a higher degree, a "half way house" paper for publication, or a verbal presentation at a Congress or similar, would carry the student's name as the second (or last author, if other co-workers had been involved), and as the first author when the paper(s) was/were reporting the results of the research activities which had been undertaken and successfully defended during the viva voce examination. Such a tactic established the interested party as a nascent and credible scientific author, and that person continued from there.

An analysis of the Contributor Roles Taxonomy (CRediT), with discussion of some of its potential pitfalls, was published last year in the journal Publications (https://www.mdpi.com/2304-6775/7/2/24).
