Tweak to co-authorship network analysis

[Nikoleta-v3]

The analysis of the co-authorship network is not convincing for me. The author created a cross-sectional map of the co-authorship network and argued that people in central positions benefit from their network. But it is not analyzed whether they benefit in anything only whether someone if centrally located or not and how dense is the network. The author did not analyze whether those who are more in a central position indeed get more collaboration subsequently or not. Further, the author said ‘Nevertheless, there are authors that do benefit from their position, but these are only the authors connected to the main cluster.’ This is a tautology as the criteria for benefitting was based on their central position.
