The present study examines the extent to which neighborhood and social psychological influences predict childhood violence among 867 African‐American youth. The results showed that neighborhood affluence was the only neighborhood‐level variable to exert a significant influence on childhood violence. Furthermore, childhood violence was significantly related to social psychological influences, such as adopting a street code, associating with violent peers, parental use of violence, and quality parenting. Overall, the findings suggested that simply living in a violent neighborhood does not produce violent children, but that family, peer, and individual characteristics play a large role in predicting violence in childhood. 相似文献

Criminal justice agencies are organized sequentially — “output” from one agency is “input” to the next — but most scholars argue that criminal justice is not a system in a theoretical sense. In this article, it is argued that general systems theory (GST) reveals important insights into criminal justice structures and functions. Specifically, it is argued that the criminal justice system processes “cases” rather than people, and that the common goal of criminal justice processing is to “close cases so that they stay closed.” It also is argued that processing capacity progressively declines, in that at each system point the subsequent agency cannot input as many cases as the previous agency can output. Each agency therefore experiences “backward pressure” to close cases in order to reduce input to the next agency. Overall, this article highlights that criminal justice agents and agencies are best understood as operating in the context of the larger whole, thus it is concluded that criminal justice is a system in the sense of general systems theory. 相似文献
