Low self-control,gender, race,and offending in late life

Self-control theory has been one of the most scrutinized general frameworks of crime for over 20 years. A majority of evidence pertaining to the theory, however, is derived from samples of teenagers and young adults. Relatively little information exists regarding whether self-control explains offending among people in late adulthood. As such, the generality of the framework has yet to be fully examined. This study uses a representative sample of people aged 60 years and older from interviews conducted in Arizona and Florida. The current study tests two key propositions regarding the generality of the theory: (1) the extent to which self-control accounts for the relationship between demographic variables and criminal offending, and (2) the invariance thesis which stipulates that self-control will have a uniform effect on offending across social groups. The analyses reveal two findings regarding theoretical generality: (1) low self-control explains late-life criminal behavior but does not account for the relationship between offending and gender, and (2) low self-control has an invariant effect on offending across gender and race when measured behaviorally. Taken together, the analyses address important elements of the supposed generality of self-control theory and extend the framework's scope to the explanation of offending in late life.

Command-level Police Officers’ Perceptions of the “War on Cops” and De-policing

Policing has been the subject of intense public scrutiny for the better part of two years after several high-profile police killings of unarmed African Americans across the United States. The scrutiny has been so extreme that some contend there is currently a “war on cops”—whereby citizens are emboldened by protests and negative media coverage of the police, and are lashing out by assaulting police officers more frequently. In response, it is argued that officers are de-policing (i.e. avoiding proactive stops). We surveyed command-level police officers from a southeastern state about their attitudes concerning the war on cops and de-policing. The majority of our sample believed there has been a war on cops over the last two years. Moreover, officers who felt strongly about the existence of a war on cops were more likely to believe that de-policing is common among officers in today’s world of law enforcement.     

乳牛子宫内膜抗菌肽BNBD5基因的克隆及其原核表达

为研发防治乳牛子宫内膜炎的抗菌肽生物制剂,根据已发表的牛抗菌肽基因序列设计了1对引物,用试剂盒提取乳牛新鲜子宫内膜总RNA,经RT-PCR扩增,将克隆的抗菌肽BNBD5基因全长编码区的cDNA连接到原核表达载体pET30a中,经IPTG诱导原核表达,通过Western-blot检测融合蛋白BNBD5的表达水平.结果表明,RT-PCR扩增出的cDNA片段长138 bp,编码45个氨基酸的多肽,多肽中合6个保守半胱氨酸残基.用Blast程序进行检索比较显示,克隆出了牛防御素家族成员BNBD5基因,并成功构建了pET30a-BNBD5载体,经IPTG诱导,pET30a-BNBD5原核表达产物的相对分子质量约为10 ku,与预期的融合蛋白大小一致,证实构建的重组质粒能够在大肠杆菌中表达.

The organizational justice effect among criminal justice employees: A meta-analysis*

Organizational justice has been shown to be an important predictor of criminal justice employees’ work-related perceptions, attitudes, and behaviors. In this study, we take stock of the organizational justice effect on criminal justice employees’ work outcomes by subjecting the literature to a meta-analysis. Multilevel modeling based on 1,924 effect size estimates drawn from 143 studies (95 independent data sets) was used to establish the empirical status of the organizational justice effect. The results indicate a sizeable relationship between organizational justice and justice system employee work outcomes (Mz = .256, CI = [.230, .283]). The findings also demonstrate that the organizational justice effect size varies slightly across several methodological variations. Specifically, the organizational justice effect size is larger when the concept is measured with scales that contain survey items tapping into all four dimensions of justice. Also, we found that outcome type, presence of confounding mechanisms, research design, and sample characteristics moderate the justice effect. We conclude that organizational justice theory is a useful framework for developing a more theoretically informed understanding of justice system employees’ work outcomes. We discuss the theoretical implications of the meta-analytic findings and avenues for future research based on the results.
