[Air-l] Stratification in social networks

[Alexander Semenov]

Hello everybody!
Does anybody know any articles, papers etc. about social networks, where  
the stratification is the main topic? All my search in Google, Jstor,  
SAGE, AoIR archieves etc. brought me papers which mention stratification  
only slightly but I want something more specific on this topic.
Thanks in advance.
