Social control theory asserts that strong social bonds inhibit delinquency, whereas weak bonds offer little resistance to offending. In the development of this theoretical perspective, new research suggests that the type and magnitude of social bonds have differing effects on male and female delinquency. This study adds to our understanding of how social control factors of parental attachment, involvement in diverse prosocial activities, belief in traditional norms, and school climate affect both young men's and young women's reports of serious delinquency and risky behavior in a sample of high school youth. Whereas previous research has generally either controlled for the effect of gender statistically or studied all-male samples, this article uses separate models to examine the independent effects of social bonds on male and female delinquency. The findings support the development of gender-specific analyses to understand how social control affects male and female pathways into delinquency.

Purpose: Extant literature indicates that individual perceptions of collective efficacy and incivilities are important in explaining fear of crime. These studies, however, often implicitly assume that the relationships between key variables do not differ between neighborhoods. The purpose of this research is to examine the relationship between perceptions of collective efficacy, perceptions of incivilities, and fear of crime and determine whether these relationships are constant between neighborhoods. Methods: Surveys were conducted using a sample of residents from four neighborhoods within Miami-Dade County. Structural equation models were used to examine the relationships between perceptions of collective efficacy, perceptions of incivilities, and fear of crime for each neighborhood separately. Tests for invariance were conducted to determine whether the coefficients from these models differed across neighborhoods. Results: Results from these analyses suggest that the relationship between perceptions of collective efficacy and fear of crime exhibit significant heterogeneity between neighborhoods, as do a number of other relationships. The relationships between perceptions of collective efficacy and perceptions of incivilities, and perceptions of incivilities and fear of crime do not exhibit heterogeneity. Conclusions: These results illustrate the importance of examining perceptions of collective efficacy within the neighborhood context. Implications for policy and future research are discussed.

a b s t r a c tIt has long been acknowledged that police officers have substantial levels of discretion in their day-to-day activities. There is a well developed body of literature that considers how this discretion is exercised across a broad array of situations including the decision to arrest, use force, and grant citizen requests for official action. Using both social disorganization and conflict theories as conceptual models, the purpose of this study was to determine if neighborhood characteristics affect police reporting behavior across a wide cross-section of reported call types. The findings indicated that reporting behavior widely varies across crime types with a greater percentage of more serious crimes translated into official crime. Neighborhood characteristics did affect reporting practices, but surprisingly only for more serious forms of disorder where discretion was perceived to be less. The findings lent support for both social disorganization and conflict theories. Theoretical implications are discussed.© 2009 Elsevier Ltd. All rights reserved. IntroductionQuestions about when and how police use discretion have been a pressing concern among scholars for decades. A large body of literature seeks to explain discretionary decision-making by police, particularly regarding the use of force and decision to arrest. Less empirical consideration has focused on how police use discretion when recording citizen reported calls for service into official crime, despite the broad effect this decision has on victims and communities.

Community-level factors such as disadvantage, disorder, and disorganization have been linked to a variety of antisocial and illicit activities. Although crime and deviance tend to concentrate in areas with these characteristics, not all residents of disorganized neighborhoods participate in proscribed activities. This study examines the relationship between exposure to community violence and involvement in assaultive behavior and weapon carrying among a sample of at-risk youth. Findings demonstrate that controlling for the effects of neighborhood disadvantage as well as other common correlates of delinquency (e.g., family supervision and structure, school attachment, and peer delinquency), youth who witnessed more violence in their neighborhoods were more likely to self-report assaultive behavior and weapon carrying. This research has important implications for the study of delinquency by further identifying the social costs of community violence.
