Book excerpt: This book includes a comprehensive survey of the theories and principles employed by sociologists, anthropologists, and other social scientists in the study of sociocultural change. Employing these tools, the later chapters examine the major trends and challenges that face today's rapidly globalizing world. Students are asked to consider how they can participate actively in shaping the events that affect their lives. Among the book's pedagogical features are well over one hundred Web sites, organized by chapter and topic, which connect the text with contemporary events and commentary.
