论“三队一室”警务模式存在的问题及完善

“三队一室”警务模式是集防范、管理、控制、打击乃至于服务于一体的运作模式,它符合社区警务要求的运作模式,能够大大促进警务效率。作为一种新模式,“三队一室”还存在推广应用、内部规范、外部协调等问题。为此,公安部应对“三队一室”作出明确的统一规定,目前,应在各地的城区派出所和有条件的乡镇派出所先实行,然后逐步推广“三队一室”模式。另外,对“三队一室”的权责应当明确,避免内部职能的冲突和外部权责的混乱。

The Frontiers of Legal Analysis: Reframing the Transition in Northern Ireland

British constitutional legal discourse is structurally limited in its capacity to capture the complexity of the Good Friday Agreement. Rather than assessing the Agreement in narrow devolutionary terms, it should be seen as a hybrid domestic and international law instrument, making an important contribution to accepted international law norms in relation to self-determination. The Agreement transforms and partly transcends the Northern Ireland conflict by substituting political contestation for violent conflict, and by defining the modalities of conducting that contestation. This analysis complements classical international law perspectives, and opens up the application of legal discourses associated with 'transitional justice' to the legal and political transformation in Northern Ireland. These discourses focus on the problem of reconciling the demands of peace with the imperatives of justice. The Agreement sits squarely in this terrain with its provisions on 'dealing with the past' and 'institutional legacies'. The insights gained here challenge orthodox thinking about conflict-management and the ongoing political process.     

ASSESSING NEIGHBORHOOD AND SOCIAL PSYCHOLOGICAL INFLUENCES ON CHILDHOOD VIOLENCE IN AN AFRICAN‐AMERICAN SAMPLE*

The present study examines the extent to which neighborhood and social psychological influences predict childhood violence among 867 African‐American youth. The results showed that neighborhood affluence was the only neighborhood‐level variable to exert a significant influence on childhood violence. Furthermore, childhood violence was significantly related to social psychological influences, such as adopting a street code, associating with violent peers, parental use of violence, and quality parenting. Overall, the findings suggested that simply living in a violent neighborhood does not produce violent children, but that family, peer, and individual characteristics play a large role in predicting violence in childhood.     

DOES CRIME JUST MOVE AROUND THE CORNER? A CONTROLLED STUDY OF SPATIAL DISPLACEMENT AND DIFFUSION OF CRIME CONTROL BENEFITS*

Recent studies point to the potential theoretical and practical benefits of focusing police resources on crime hot spots. However, many scholars have noted that such approaches risk displacing crime or disorder to other places where programs are not in place. Although much attention has been paid to the idea of displacement, methodological problems associated with measuring it have often been overlooked. We try to fill these gaps in measurement and understanding of displacement and the related phenomenon of diffusion of crime control benefits. Our main focus is on immediate spatial displacement or diffusion of crime to areas near the targeted sites of an intervention. Do focused crime prevention efforts at places simply result in a movement of offenders to areas nearby targeted sites—“do they simply move crime around the corner”? Or, conversely, will a crime prevention effort focusing on specific places lead to improvement in areas nearby—what has come to be termed a diffusion of crime control benefits? Our data are drawn from a controlled study of displacement and diffusion in Jersey City, New Jersey. Two sites with substantial street‐level crime and disorder were targeted and carefully monitored during an experimental period. Two neighboring areas were selected as “catchment areas” from which to assess immediate spatial displacement or diffusion. Intensive police interventions were applied to each target site but not to the catchment areas. More than 6,000 20‐minute social observations were conducted in the target and catchment areas. They were supplemented by interviews and ethnographic field observations. Our findings indicate that, at least for crime markets involving drugs and prostitution, crime does not simply move around the corner. Indeed, this study supports the position that the most likely outcome of such focused crime prevention efforts is a diffusion of crime control benefits to nearby areas.     

非洲猪瘟CD2v胞外区基因片段的真核表达及其多克隆抗体的制备

本研究利用真核表达系统表达非洲猪瘟病毒的CD2v胞外区蛋白,研究其免疫特性,制备多克隆抗体并研究其性质,为研发特异性单抗奠定数据基础。以非洲猪瘟病毒Wuhan2019-1株(GenBank:MN393476.1)为模板,合成CD2v胞外区基因序列,并将其克隆至真核表达载体pCAGGS载体中,获得pCAGGS-CD2v胞外区重组质粒。经酶切和测序鉴定后,将重组质粒转染293F细胞,获得重组胞外CD2v蛋白(简称His-CD2v)。用Ni-NTA柱纯化His-CD2v,并以此为抗原免疫BALB/c小鼠制备多克隆抗体,利用ELISA和间接免疫荧光对多克隆抗体进行鉴定。结果显示,(1)His-CD2v融合蛋白在293F中以可溶形式表达,SDS结果显示,相对分子质量约为35~80 ku的弥散带;(2)融合表达的His-CD2v能与阳性血清反应,与对照不反应;(3)HisCD2v制备的多抗效价最高达1∶218700,且能与阳性血清竞争性结合CD2v抗原。上述结果表明,His-CD2v融合蛋白的表达及其多抗的成功制备,为进一步筛选CD2v特异性单抗及研制竞争ELISA试剂盒,为非洲猪瘟感染与免疫鉴别方法的建立奠定了坚实的基础。     

Gender Differences in Self-Perceptions and Academic Outcomes: A Study of African American High School Students

There is increasing divergence in the academic outcomes of African American males and females. By most accounts, males are falling behind their female peers educationally as African American females are graduating from high schools at higher rates and are going on to college and graduate school in greater numbers. Some have suggested that school completion and performance is associated with how students feel about themselves. The purpose of this study was to explore gender differences in the relationship between self-perceptions and 2 academic outcomes among a sample of 243 African American high school sophomores. The results suggest that, overall, females are more favorably oriented toward high school completion. Both male and female students with more positive self-perceptions have stronger intentions to complete the current year of high school. Higher grade point averages were more strongly associated with greater self-efficacy for females than for males. Given these findings, increased attention to educational programming, societal messages, and future research is warranted.
