Book excerpt: For the Third Edition of Investigating Social Problems, editor A. Javier Treviño, has gathered a panel of top experts to thoroughly examine all aspects of social problems, providing students with a contemporary and authoritative introduction to the field. Each chapter is written by a well-known specialist on the topic being covered. This unique, contributed format ensures that the research and examples described are the most current and relevant available. In addition, the experts use both general theoretical approaches (structural functionalism, conflict theory, symbolic interactionism) as well as specialized theories chosen to bring additional insight and analysis to their assigned topics. The text is framed around three major themes: intersectionality (the interplay of race, ethnicity, class, and gender), the global scope of many problems, and how researchers take an evidence-based approach to studying problems. This title is accompanied by a complete teaching and learning package.
