This unit examines the social history of childhood and the emergence of categories of delinquency and dependency. It also discusses the roles of various government and non-government organisations that deal with the needs of youth. Sociological and criminological theories of delinquent behaviour are considered. Relevant policy issues are also studied. Methodologies for measuring and analysing variables related to youth and policy are discussed. Assessment through examination requires broad understanding of the concept of youth, the behaviours associated with youth, and policies regarding youth. Assessment through mid-term research papers requires specific analytic practices and conceptual development around focussed substantive research.
