Exploring digital distinctions and inequalities, sociologists and information and communication scholars discuss new perspectives on digital stratification; diversities of usage, social class, and capital; emotions and disposition; open wi-fi and mobile networks; and public policy. Among their topics are cultural stratification on the Internet: five clusters of values and beliefs among users in Britain, understanding Internet use by teenagers from different social backgrounds, the impact of emotional costs on student learning outcomes, inter-ethnic ties with mobile communications in homogeneous and ethnically mixed cities: a structural diversification approach, and an analysis of a public policy program on digital inclusion in California.
