Overview of: “Getting the Law Involved a Quasi-Experiment in Early Intervention Involving Collaboration Between Schools and the District Attorney's Office”

Research Summary Precursors to serious and chronic delinquency often emerge in childhood, stimulating calls for early interventions. Most intervention efforts rely solely on social service programs—often to the exclusion of the juvenile justice system. The juvenile justice system has been reluctant to become involved in the lives of relatively young children fearing net widening or further straining resources that could be used for older youth with documented delinquency histories. We report here the results of an early intervention program sponsored by and housed in a district attorney's office in Louisiana. Using a quasi-experimental design, we examined outcomes associated with program involvement as well as whether the obvious involvement of the prosecutor's office was associated with further reductions in problem behavior.

• 1 : The results revealed that significant reductions in problem behaviors of young children could be attributed to program participation.
• 2 : The obvious involvement of the district attorney's office, however, was associated with limited, albeit significant, reductions in specific problem behaviors.
• 3 : These findings show that successful early intervention efforts can be made part of the juvenile justice system and that in some limited situations prosecutorial involvement can result in positive outcomes.

Policy Implications The expansion of early intervention programming into the juvenile justice system offers opportunities to address early problem behavior. Our study and its results have the following policy implications.

• 1 : Closely coupled partnerships between schools and the juvenile justice system can effectively address, mitigate, and perhaps prevent an early onset of antisocial behavior.
• 2 : Even so, coupling early intervention efforts to the mission of the juvenile justice system warrants debate. Net-widening, resource diffusion, and the potential for officials to rely too heavily on the deterrent characteristics of the justice system represent serious threats to the integrity of effective early intervention programs.
• 3 : We suggest substantial debate and consideration is given before coupling early intervention efforts to the juvenile justice system.

     

Police Officers on Drug Corners in Philadelphia,Drug Crime,and Violent Crime: Intended,Diffusion, and Displacement Impacts

On May 1, 2002, the Philadelphia Police Department launched Operation Safe Streets, stationing officers at 214 of the highest drug activity locations in the city 24 hours a day, 7 days a week. Interrupted time series (AutoRegressive Integrated Moving Average) models on weekly data isolated citywide and local program impacts on all violent crimes, murder, and reported drug crimes. Results showed no significant impacts on citywide weekly counts for drug crimes, homicides, or all violent crimes. Geographically focused analyses showed significant localized intervention impacts for both violent and drug crimes. Analyses of high‐drug‐activity non‐intervention sites suggest: the program impacts seen were not an artifact of history or local history; significant spatial diffusion of preventive benefits for violent crime; and probably significant spatial displacement for drug crime. Stationary targeted drug‐enforcement interventions like Operation Safe Streets may differentially affect the locational selection processes behind violent crime versus drug crime.     

股东关系维度代理问题及其治理机制研究

股东“异质化”的现实演进和股东关系的弱式平等使得股东关系维度代理问题日渐成为公司治理的重点与难点。股东关系维度代理问题在中国股份公司中有其特殊性,如股东间的代理关系情境极其复杂、控制权私利攫取成本较低、中小股东消极主义尤为明显、多元维度代理问题相互交织等。公司立法必须注重强化自治和利益平衡,多措并举构建防范股东关系维度代理问题的结构性治理机制。
