This dynamic text on human behavior takes a unique international perspective to introduce students to the concepts of large social systems and development. Social workers now practice in an increasingly global context for reasons ranging from migration to international adoptions to developments in technology. Understanding these global connections is essential to social workers today. Human Behavior in a Just World emphasizes the "common human condition" between people, and encourages students to see the powerful connections between environmental conditions and behavior. The authors address key elements of human behavior through a global lens, and discuss powerful global policy instruments and resources, such as the United Nations. Engaging North American and global case studies illustrate the theories in practice.
