Ok, you may want to browse Jurnal Komunikasi or International Journal of Communication published by School of Media and Communication, UKM. There are articles in that journal written by academicians from Malaysia particularly on social media. 

You might also want to look at Daniel Miller and Mirca Madianou's contribution on polymedia.

Dear Karun

In the Journal of Computer-Mediated Communication surely find information that will be useful; some works of D. Boyd and N. Ellison could also contribute to your goal.

I hope I have been helpful. Good luck with your interesting study.

A hug

Dear all

Thank you very much for your valuable inputs,

Really appreciate your contribution,

Regards,

Karun....!

OECD global Pulse is undertaking some practical studies that might be of interest

In Brazil, we have a public policy named "Ponto de Cultura Indígena". We can translate it as a culture station to indigenous people . It is a kind of entity which is able to connect indigenous people to virtual world from own communities or tribes. In Brazil, we have a lot of culture stations around the country where people access for cultural purposes, as education, communication or debate about cultural diversity. Actually, the culture stations are not only in indigenous people tribes, but in a lot of minority communities where there are some kind of culture activity. You can read more about this at :
