Sommario/riassunto

What are the major issues confronting social policy-makers today? What theoretical perspectives shape our thinking about the causes of social problems and how we should respond? What can we do to influence decision makers about which policy choice to make?     In this completely revised and updated edition of Canadian Social Policy, a new generation of social policy analysts discusses these important questions.     Readers who are interested in discovering the current policy debates, and who want to understand the policy-making process at various levels of government as we

Sommario/riassunto

This introductory book uses the moving frame as a tool and develops Finsler geometry on the basis of the Chern connection and the projective sphere bundle. It systematically introduces three classes of geometrical invariants on Finsler manifolds and their intrinsic relations, analyzes local and global results from classic and modern Finsler geometry, and gives non-trivial examples of Finsler manifolds satisfying different curvature conditions.
