Objectives
The relatively weak quasi-experimental evaluation design of the original Boston Operation Ceasefire left some uncertainty about the size of the program’s effect on Boston gang violence in the 1990s and did not provide any direct evidence that Boston gangs subjected to the Ceasefire intervention actually changed their offending behaviors. Given the policy influence of the Boston Ceasefire experience, a closer examination of the intervention’s direct effects on street gang violence is needed.Methods
A more rigorous quasi-experimental evaluation of a reconstituted Boston Ceasefire program used propensity score matching techniques to develop matched treatment gangs and comparison gangs. Growth-curve regression models were then used to estimate the impact of Ceasefire on gun violence trends for the treatment gangs relative to comparisons gangs.Results
This quasi-experimental evaluation revealed that total shootings involving Boston gangs subjected to the Operation Ceasefire treatment were reduced by a statistically-significant 31 % when compared to total shootings involving matched comparison Boston gangs. Supplementary analyses found that the timing of gun violence reductions for treatment gangs followed the application of the Ceasefire treatment.Conclusions
This evaluation provides some much needed evidence on street gang behavioral change that was lacking in the original Ceasefire evaluation. A growing body of scientific evidence suggests that jurisdictions should adopt focused deterrence strategies to control street gang violence problems. 相似文献142.

This paper explores the role and impact of advertising in the French urban planning on citizens’ perception with a close examination of the implications and connections between citizens and outdoor advertising. Significant changes in quantity and form of outdoor advertising have been defined under French regulations. Our knowledge is now mass mediated in public spaces. More and more visible and gargantuan advertising signs surround and even invade our environment for strict commercial benefits. The ‘invasion’ of commercial signs can be compared to a visual pollution affecting our perception, autonomy in thinking and health depending on the part of the population being considered. 相似文献

Australia has experienced one of the fastest growing public debt levels in the world post‐Global Financial Crisis due to a series of large federal budget deficits driven by high government spending. In this paper we examine the balance sheet implications of this escalating public debt, before proposing some macro‐fiscal objectives for determining its sustainable level. These objectives are to (i) restore the federal government's solvency; (ii) eliminate foreign public debt; and (iii) achieve budgetary balance over the business cycle. Empirically, we first examine how much fiscal consolidation is required for debt stabilisation at current levels, before considering what sized budget balances are needed to achieve the target debt to GDP ratios consistent with the proposed objectives. The results show that no target debt to GDP level consistent with the optimal levels will be met on current fiscal settings in the medium term. This implies significantly greater fiscal consolidation is required to minimise future fiscal risk. 相似文献

This article discusses the opportunities and challenges associated with the use of quantitative participatory methods and participatory numbers for integrating locals’ and outsiders’ knowledge, as well as actions from the bottom-up and top-down, in development. It places emphasis on the contribution of quantitative participatory methods and participatory numbers to foster dialogue between a wide range of stakeholders, for example, local people, NGOs, government agencies and scientists, who usually seldom directly engage with each other. The article draws on case studies that discuss remittances and disasters in Samoa, and disaster risk reduction in the Philippines. 相似文献
