Objectives

Examine relationships between routine activities, character contests in the form of “signifying,” and general delinquency and fighting in a street gang context.

Methods

Samejima’s (Estimation of latent ability using a response pattern of graded scores. Psychometrika monograph supplement 17. Psychometric Society, Richmond, VA, Retrieved 10 Aug 2011, from http://www.psychometrika.org/journal/online/MN17.pdf, 1969) graded response models and multilevel ordinal logistic regression models are estimated using data from Short and Strodtbeck (Group process and gang delinquency. University of Chicago Press, Chicago, 1965) study of street gangs in Chicago, 1959–1962. The primary sample consists of 490 boys representing 10 black gangs, 4 white gangs, 9 black lower-class groups, 4 white lower-class groups, 2 black middle-class groups, and 2 white middle-class groups.

Results

Unstructured and unsupervised socializing with peers significantly increased the likelihood of delinquency among the boys and explained a significant portion of the group-level gang effect. In addition, the more time the boys spent hanging in the streets and attending parties, the more likely they were to participate in signifying, which, in turn, increased their risk of fighting.

Conclusions

Findings provide evidence that gangs contribute to delinquency partly through their effect on the routine activities of members. Findings also suggest that signifying is an important mechanism by which unstructured and unsupervised socializing with peers leads to violence.  相似文献

Following 9/11, the Department of Homeland Security established the Container Security Initiative (CSI) programme in 2002 in response to the threat from terrorist attacks involving weapons of mass destruction transported by cargo containers. This project establishes the tracking and targeting of ‘high risk’ containers and their subsequent scanning with X‐ray machines before loading onto the U.S. bound ships. To date, 44 of the world's largest ports have agreed to become CSI‐compliant, the majority of which are located in industrialised countries, while developing and least developed countries are under‐represented. CSI‐eligibility requires that ports represent a considerable volume of U.S. bound container traffic and invest in container scanning devices. Every non‐intrusive inspecting device (NII) costs several million dollars while investments in IT and existing infrastructure often triple the compliance costs. Containers originating in a CSI port are expedited through U.S. customs, representing a comparative trade barrier for exporters from non‐CSI ports. Thus, CSI acts as a tool for the U.S. to improve security, while representing a challenge to exporting countries' market access. This article provides an evaluation of the impacts this plan will have on the export competitiveness of developing countries. It reviews the potential benefits this programme offers in terms of improved trade facilitation, as well as proposing recommendations for its expansion to include developing countries.

The first part of this article examines the development of the career structure of the British diplomatic establishment after the reforms of 1919-20, arguing that the peripatetic career identified with the prewar Diplomatic Service became increasingly common for all members of the new amalgamated service between the two world wars. The average length of posting to an overseas mission or one of the geographical departments in London seldom exceeded three years or so. The second part of the article then speculates on the impact of the peripatetic career on the effectiveness of the British diplomatic establishment, suggesting that it had both postive and negative impacts.  相似文献
