Dear Gohar Feroz,
We don’t know the subject, but if you have such a large cluster of 326 institutions, the network may be very globalized.
Individuals can then team up within this internationalized and networked domain?
Just a hypothesis.

Subject: [SIGMETRICS] Collaboration network puzzle
Please help me solve the following puzzle.
Using the Web of Science publication data, I have constructed two networks, 1) author level collaboration network, and 2) institutional level collaboration networks. The publications are in a particular research field.
The problem is that the author network is composed of several small disconnected clusters with largest component consisting of only 43 nodes or authors. However, the institutional level collaboration network is well connected with 326 institutions in a single component.
I just wonder what could explain these differences? Normally, when I construct such networks, the institutional network is sparse as compared to the authors network, as all the publications (or nodes) from a particular institute are merged into a single node when creating an institutional level collaboration network. But, here it is the opposite.
What could cause this to happen? Any ideas?
