Emphasizing the principles of interdependency and collective self-efficacy, Hoffman (psychology, California State U. Northridge) discusses group work from an evolutionary standpoint, research on how community service fosters cooperative learning and the overcoming of intergroup prejudices and conflicts, and as a cure for midlife crisis. The book includes examples of community service projects, and personal perspectives on immigration reform and ethnocentrism and how community service has changed lives. Coauthors are Cal State students and the developer of the CCC Cultural and Fine Arts Academy, which enrolls students from diverse backgrounds.
