Relying on extensions of routine activities and social disorganization theories, we examine whether 1) neighborhood social characteristics shape opportunities for the development of unstructured socializing with peers among adolescents, 2) whether unstructured socializing leads to an increase in violent behavior within urban communities, and 3) whether neighborhood collective efficacy modifies the impact of unstructured socializing on violence. The study outlined in this article uses three waves of data from the Project on Human Development in Chicago Neighborhoods Community Survey and Longitudinal Cohort Study. Results from multilevel linear models suggest that neighborhood collective efficacy supports the development of unstructured socializing with peers. Multilevel Rasch models of violent behavior indicate that, consistent with previous research, unstructured socializing is a powerful predictor of violence. Collective efficacy exerts an independent influence on violent behavior and attenuates the effect of unstructured socializing on this outcome.

Although schools in the United States adopted harsher disciplinary policies in the early 1990s, to date, there is little evidence showing whether severe school sanctions against student misconduct prevent crime. Drawing on both deterrence and rational choice theories, we test the proposition that harsh school‐based policies against violence reduce students' involvement in violent behavior. However, in contrast to prior research that explores the direct link between sanctions and student behavior, we emphasize the role of school sanctions in adolescent cognitive decision‐making processes, hypothesizing that school sanctions against violence condition the effect of thoughtfully reflective decision making (TRDM) on adolescent involvement in violent behavior. We use data from the first two waves of the National Longitudinal Study of Adolescent Health to test our research hypotheses. The results from a series of multilevel models show that more severe school sanctions against violence (i.e., home suspension and expulsion) disarm the process of cognitive reflection and attenuate the effect of low TRDM on violent offending.

System trespassing by computer intruders is a growing concern among millions of Internet users. However, little research has employed criminological insights to explore the effectiveness of security means to deter unauthorized access to computer systems. Drawing on the deterrence perspective, we employ a large set of target computers built for the sole purpose of being attacked and conduct two independent experiments to investigate the influence of a warning banner on the progression, frequency, and duration of system trespassing incidents. In both experiments, the target computers (86 computers in the first experiment and 502 computers in the second) were set either to display or not to display a warning banner once intruders had successfully infiltrated the systems; 1,058 trespassing incidents were observed in the first experiment and 3,768 incidents in the second. The findings reveal that although a warning banner does not lead to an immediate termination or a reduction in the frequency of trespassing incidents, it significantly reduces their duration. Moreover, we find that the effect of a warning message on the duration of repeated trespassing incidents is attenuated in computers with a large bandwidth capacity. These findings emphasize the relevance of restrictive deterrence constructs in the study of system trespassing.
