Chapter Specific Changes Chapter 1 now emphasizes the relevance of crime theories for crime control policy and criminal justice practices to better illustrate the connectivity between theories of crime and public policy prevention and enforcement initiatives. Chapter 2, "Classical and Neoclassical Criminology," has been refined to relate the evolution of the classical perspective to modern deterrence and rational choice theories. Chapter 3, "Biological Theories of Crime," has been rewritten and brings expanded and more contemporary biosocial research-based knowledge to this edition. In order to include the leading elements of the quickly growing biosocial perspective, the authors have trimmed down the sections on Physiognomy and on Body Type Theories and added new discussion of evolutionary psychology, biochemistry, and neurophysiology. The revised chapter also features a completely new section titled "Contemporary Biosocial Criminology." This section offers an in-depth overview of the four factors highlighted by modern biosocial criminology as being important for understanding criminal behavior: 1) biological factors; 2) genetic factors; 3) the brain; and 4) the environment. Each of these four factors is discussed in turn in separate subsections of the chapter. This chapter also now includes the role of neurotransmitters and the frontal cortices in the development of human behavior.
A thorough treatment of these points has been added to the revised chapter in a subsection covering the brain. Chapter 4, "Psychological Theories of Crime," offers a substantial expansion on life course theory (especially Sampson and Laub''s theory), antisocial personality disorder, and IQ. The antisocial personality disorder section of the chapter has been revised in two major respects. First, all material referencing the DSM-IV has been updated to reflect the recently revised manual (i.e., the DSM-5). Second, the discussion of the etiology of the disorder has been revised by tying in information discussed in chapter 3 (i.e.
, biological and genetic factors). The section covering the IQ-crime link has been revised to discuss the most recent evidence gleaned from intelligence-based research. This chapter also now covers psychological constructs such as sensation seeking across two new sections (Dual Systems Theory and Self-control/Self-regulation. Chapter 5, "The Social Ecology of Crime," offers additional social disorganization theory examples. Chapter 6, "Learning and Cultural Transmission Theories of Crime," highlights social learning-social structure theory while better emphasizing the oppositional culture perspective. Chapter 7, "Strain Theories of Crime," and Chapter 8, "Control Theories of Crime," provide coverage of both seminal (e.g., Hirschi''s original control theory) and extended (e.
g., Agnew''s general strain theory) versions of strain theory. Chapter 9, "Theories of Social Conflict," has been heavily revised and now features expanded coverage of the Cultural Criminology, Feminist Criminology, and Labeling theories sections. A new section on Reintegrative Shaming (the theoretical basis of restorative justice) has been added in a separate new section and provides new examples illustrating the chapter''s central concepts. Chapter 10 is about a fourth longer than the last edition with a new section (Theory Informing Policy and Practice) that ties together in application the idea of what theory is and how it is useful and connects to concepts and issues introduced in Chapter 1, thereby bringing students full circle in regards to the theory-policy link.
