犯罪均值频率——一种犯罪时间分布的测度指标

犯罪在时间分布方面有其特定规律,常规的犯罪总数或平均数等统计量存在不稳定性、偏差性和数据保密性等问题,不利于犯罪时间分布特征的客观对比分析。犯罪均值频率指标克服了传统时间分布统计量存在的问题,可以用来分析犯罪是否偏好发生于特定的时间内,满足了犯罪时间分布规律分析需求。运用该指标对某市5年内的入室盗窃犯罪在星期日别、月份上的时间分布规律进行了实证研究,结果表明,入室盗窃在该市3月份和9-12月份表现为高发期,而在周末则表现为犯罪低谷期。     

THE ECOLOGY OF GANG TERRITORIAL BOUNDARIES*

Within any type of system, the actors in the system inevitably compete over resources. With competition comes the possibility of conflict. To minimize such effects, actors often will partition the system into geographic territories. It is against the larger ecological backdrop of competition and conflict that we examine territory formation among urban street gangs. Although previous studies have examined the social and built environment where gangs form, and how the presence of a gang influences local levels of violence, we know little about how competitive interactions are tied to the formation and maintenance of gang territories. We use formal spatial Lotka–Volterra competition models to derive hypotheses about competition‐driven territory formation. By using data on 563 between‐gang shootings, involving 13 rival street gangs in the Hollenbeck Policing Division of Los Angeles, we show that violence strongly clusters along the boundaries between gangs in a way that is quantitatively predicted by the theory. The results suggest that even weak competitive interactions between gangs are sufficient to drive gang territory formation without recourse to other processes or assumptions.     

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.     

Gang Membership,Gun Carrying,and Employment: Applying Routine Activities Theory to Explain Violent Victimization Among Inner City,Minority Youth Living in Extreme Poverty∗

Conceptual inconsistencies in routine activities theory are illustrated by demonstrating how gang membership, gun carrying, and employment can be categorized as both risk and protective factors in a high‐poverty context. Two waves of longitudinal data from a high‐poverty sample of African American youth were used to examine the determinants of victimization risk. Bivariate analyses indicated that gang membership, gun carrying, and employment status are significant risk factors for violent victimization, but these effects were mediated by measures of lifestyles (e.g., demographic and family factors, deviant lifestyles) included as controls in the full multivariate model. In other words, the strong positive relationship between gang membership and gun carrying found in previous studies may be due to model misspecification and/or the lack of research on high‐poverty samples of inner city youth from the Deep South. Additional logistic regression analyses also indicate that the number of hours employed per week (but not employment status) is a risk factor for violent victimization. Finally, the theoretical implications of these findings for routine activities theory are discussed.     

Local Social Ties and Willingness to Intervene: Textured Views Among Violent Urban Youth of Neighborhood Social Control Dynamics and Situations

Social control in urban neighborhoods has been studied for over a century in America, yet our understanding of the dynamic nature of social relations for exerting informal social control remains limited. The present study uses detailed reports from those most likely to be the target of local control efforts—violent youth in extremely disadvantaged urban locations—to re‐examine two features of this work: variations across different hypothetical scenarios widely used in this research, and connections between local ties and intervention type and likelihood in actual events. In‐depth qualitative interviews from 159 violent males aged 16–24 from two distressed New York City neighborhoods identify ways in which responses to commonly used scenarios of informal social control are age‐ and space‐graded. Reports on the transactional nature of social control in violent events show how local ties may undermine, rather than support, social control processes. It would appear that we need to consider more carefully general suggestions about local ties encouraging more informal social control, move to a more textured, multithreaded view of these connections, and incorporate age‐ and space‐graded dynamics into future studies of social control.     

Prevalence and Characteristics of Co‐Offending Recruiters

Previous examinations of co‐offending have identified a subset of high‐rate offenders who commit crimes with a large number of co‐offenders, most of whom are younger and less criminally experienced. These so‐called “recruiters” are of particular interest to researchers and practitioners, because of their potential role in facilitating offending onset and recidivism among their co‐offenders. In this paper, data on 61,646 individuals detected by a large UK police force are used to identify offenders who fitted the recruiter profile, and to compare their individual and offending characteristics with those of non‐recruiters. In total, 86 recruiters were identified. In multivariate analyses, recruiters were found to be older than non‐recruiters and were typically involved in property crimes. In addition, they tended to offend in criminal groups that were more heterogeneous and stable than non‐recruiters. These findings suggest that a small but identifiable group of recruiters can be detected using official data and that these individuals may be important targets for police attention and court treatment.     

《大清律例》“夫尊妻卑”对夫犯妻的影响——以“夫因生活琐事杀妻”案为考察中心

在清代,朱子理学是统治阶级所尊奉的正统学说,《大清律例》具有典型的"夫尊妻卑"特征,这主要体现在夫妻权利义务不对等、夫妻相犯同罪异罚两个方面。在刑科档案中,夫因生活琐事杀妻是导致夫殴妻至死的最主要原因,且在夫杀妻案件中占较大的比例。《大清律例》的"夫尊妻卑"规定,纵容了夫权的肆意膨胀,致使清律为倡导"素相和好"的夫妻关系而试图约束夫犯妻,尤其是夫殴妻致折伤以上的目的无法达到。     

包庇黑社会性质组织罪若干问题研究

包庇黑社会性质组织罪是指国家机关工作人员包庇黑社会性质组织的行为。它是修订后的刑法在第 2 94条第 4款所增加的一个新罪名。本罪所侵犯的直接客体是什么 ?包庇的对象是否只能是“黑社会性质的组织” ?“包庇”行为如何界定以及本罪的立法是否需要进一步的完善等问题均值得研究     

破坏野生动物资源类犯罪若干疑难问题研究

破坏野生动物资源类犯罪为法定犯。但由于行政法、刑法以及司法解释关于野生动物犯罪相关规定存在一定的冲突,特别是在动物保护等级、保护对象、升档标准等方面,导致司法实践在法律适用方面存在众多困难。而在司法实践中,关于动物犯罪案件司法鉴定、主观明知、违法性认识、证明标准等方面也存在不同的观点。
