This thoroughly revised new edition looks at the nature of social networks, their changing configurations, and the forces of influence they unleash in shaping the life experiences of young people between the ages of 12 and 25 years. The author draws on both social and psychological research to apply network thinking to the social relations of youth across the domains of school, work and society. Network thinking examines the pattern and nature of social ties, and analyses how networks channel information, influence and support with effects on a wide range of life experiences. The book comprises eleven chapters, which contain discussion on key topics, such as youth transitions, network analysis, friendship, romantic ties, peer victimization, antisocial behaviour, youth risk-taking, school motivation, career influence, youth citizenship, and community organizations for young people. Chapters contain discussions of practical ways in which schools can provide support, and suggestions for youth organizations on how to assist young people to become effective citizens.
