This book presents the conception of a system of social identities, including the system's structure, development and dynamics, and explores the influence of cultural dimensions and identity salience on attitudes, behavior, and the structures of consciousness. The "Four C" model of identity-based conflicts provides fresh opportunities for analyses of the role of identity in conflicts and violence. Karina V. Korostelina introduces a model of dealing with identity conflicts that includes early warning, identity based training, management of multicultural communities, identity reconstruction workshops, and negotiation of identity. Every theoretical chapter in the book is followed by examples of research and methodological tools for analyzing data on social identities and identity based conflicts.
