Area Differences and Time Trends in Crime Reporting: Comparing New York with Other Metropolitan Areas

Police measures of crime are shaped by victims’ decisions to notify the police. To obtain a better understanding of US crime trends, this study uses the National Crime Victimization Survey to examine geographic differences and temporal trends in crime reporting in New York and other metropolitan areas for the period 1979-2004. We find that net of crime characteristics and survey methodology, the New York metropolitan area showed fewer increases in crime reporting than did other metropolitan areas. These divergent trends suggest that the real differences in the drop of nonlethal violence between New York and other areas may have been smaller than those indicated by police-based crime statistics. We also find that from the early 1990s to 2004, New York showed a sharp decrease in the likelihood of victims perceiving that “police wouldn’t help.” This trend suggests that police reforms in New York City have not resulted in more victims using police-related reasons to explain their nonreporting behavior. Instead, researchers need to develop a broader theoretical framework (not an exclusive focus on police actions) to understand how police- and nonpolice-related factors may explain the geographic variation in the trends of reporting observed in this study.     

植物DNA检验技术在命案现场重建中的应用策略

植物DNA检验技术是利用植物遗传性状的稳态性对关联植物物证进行检验鉴定的手段。将该技术应用于现场重建,应基于植物物证与犯罪嫌疑人、被害人及其活动环境具有＂重大关联性＂。从命案现场重建的需求上看,应围绕犯罪嫌疑人及其可控物品中附着植物与现场植物的种属同一性判断、被害人尸体（尸块或尸骸）及其随附物品中附着植物与中心现场植物的种属同一性判断、疑似侵害物及其附着植物与嫌疑人行为关联植物的种属同一性判断等三个角度或层次进行检验和综合分析。植物DNA检验技术可阐明物证的时空运行停顿规律,为命案现场重建工作提供一种参考性解决方案。

Licensed firearm dealers,legal compliance,and local homicide: A case study

Research summary

This study uses a combination of tract-level and street network-level analyses to examine: (1) the overall association between federally licensed firearm dealers (FFLs) and homicides, (2) the relationship between dealers with serious violations (such as selling to prohibited buyers or failing to record sales) and homicide, and (3) whether the dealer–homicide association is moderated by community disadvantage. Results replicate and confirm a relationship between dealers and homicides in disadvantaged neighborhoods. Importantly, however, we also find that proximity to noncompliant dealers specifically elevates the risk of lethal violence.

Policy implications

We detail how a coordinated effort between federal, state, and local agencies to regulate firearm dealers and ensure that legal compliance can be instrumental in reducing gun violence. There is a clear need for increased oversight of gun dealers and more robust policies that hold negligent dealers accountable, including the necessary funding and regulatory manpower to enable regular auditing and support consistent follow-up for noncompliant dealers. A comprehensive policy framework that supports supply-side gun violence reduction should include additions to state-level laws that require record keeping, videotaping and store security, and regular inspection for firearm dealers.

Russia’s economic policy in 2015–2016: the imperative of structural reform

In the aftermath of the global economic crisis, we have seen uneven development in the leading advanced and emerging economies, new models of economic growth that vary from country to country, uncertain prospects for globalization and challenges of “regional globalization,” looming currency re-configurations, as well as shifting energy price dynamics and their influence on political and economic prospects of particular states. This paper discusses current challenges for social and economic policy in the context of the history of the past 30 years. With reference to Russia, it focuses on a new growth model, structural transformation (including import-substitution issues), economic dynamics, fiscal and monetary concerns, and social issues. It concludes by addressing the priorities of economic policy.
