Objectives
Many studies utilize time series methods to identify causal effects without accounting for an underlying time trend. We show that accounting for trends changes the conclusions in the study of Chapman et al. (JAMA, 316(3), 291–299, 2016), who evaluated the impact of the Australian firearm law in 1996. We also introduce a new empirical method that tests whether their empirical strategy can actually identify a causal effect that is also useful for panel analyses.Methods
We use national data from the Australian Bureau of Statistics, assembled in annual counts of: total firearm deaths, firearm suicides, and firearm homicides. These data are used in an independent re-analysis of the impact of the 1996 Australian firearm law that accounts for underlying stochastic trends. We then estimate a series of artificially created interruptions using interrupted times series analysis in a time frame before 1996, to test for changes in the slope of mortality across several years prior to the actual regulatory changes. This tests whether the empirical model produces effects in years other than the year of the intervention, thereby testing if the results can simply be replicated at random using other interruption years.Results
Controlling for stochastic trends produces less statistical evidence of the impact of the firearm law on firearm mortality than previously reported by Chapman et al. (JAMA, 316(3), 291–299, 2016). Introducing artificial interruptions in 1990 through 1995 produces statistically significant decreases in all firearm-related mortality measures well above the expected type 1 error. Overall, 19 out of the 36 artificial interruption models we tested were found to be statistically significant, suggesting that the empirical model can be implemented in multiple non-intervention years with results similar to the true 1996 interruption year.Conclusions
Current evidence showing decreases in firearm mortality after the 1996 Australian national firearm law relies on an empirical model that may have limited ability to identify the true effects of the law.233.

In the 1970s and 1980s, a handful of legal theorists addressed the problem of criminal justice for offenders who faced criminogenic social disadvantages. Their discussions were provocative but alternatively unpersuasive and underdeveloped. More recently, in the wake of mass incarceration in America, philosophers have put forth new analyses that make important headway but remain scattered, partial, and in need of a systematic and integrated review. In this article, I reconstruct and critique the most prominent and well-developed explanations yet offered of the distinctive moral problems that offenders’ criminogenic social disadvantages may pose for criminal justice. I conclude that some views are misguided, others are unduly limited, and one – based on the ideals of fair opportunity to avoid crime and punishment – is particularly promising but as yet underdeveloped. 相似文献

Adding Security,but Subtracting Safety? Exploring Schools’ use of Multiple Visible Security Measures
Emily E. Tanner-Smith Benjamin W. Fisher Lynn A. Addington Joseph H. Gardella 《American Journal of Criminal Justice》2018,43(1):102-119
In response to continued concerns over crime and violence, schools are increasingly employing visible security measures such as cameras, metal detectors, and security personnel. These security measures are not mutually exclusive, but few studies have considered the relationship between the use of multiple forms of security and youth’s exposure to drugs, fighting, property crime, and firearms at school. To address this issue, we analyzed nationally representative school administrator-reported data from the School Survey on Crime & Safety, using a quasi-experimental design with propensity scores to adjust for potential confounding factors. The results indicated that utilization of multiple security measures reduced the likelihood of exposure to property crime in high schools, but most other security utilization patterns were associated with poorer school safety outcomes. Our findings provide guidance to policymakers in considering whether to use – or expand – visible school security measures in schools. 相似文献

Students’ Feelings of Safety,Exposure to Violence and Victimization,and Authoritative School Climate
Benjamin W. Fisher Samantha Viano F. Chris Curran F. Alvin Pearman Joseph H. Gardella 《American Journal of Criminal Justice》2018,43(1):6-25
Although many students feel unsafe at school, few malleable factors have been identified to increase students’ feelings of safety. Drawing on criminological behavior control theories, this study posits authoritative school climate as one such factor. With data from two nationally representative datasets, this study uses path analysis to examine the relationship between authoritative school climate and feelings of safety, as well as the extent to which this relation is explained by exposure to violence and victimization. Across both datasets, a more authoritative school climate was associated with increased feelings of safety at school. Both models also indicated that this relationship was explained in part by reduced exposure to violence and victimization, although the strength of this indirect effect varied across models. These findings suggest that strengthening students’ relationships with adults and increasing the fairness and consistency of rules in the school may both reduce exposure to violence and victimization and help students feel safer at school. 相似文献

Endowed with the state monopoly on the legitimate use of even potentially lethal force, it is intolerable for police officers to act outside the governing legal and ethical framework. At the same time, officers are expected to exert self-control and refrain from excessive use of force when they deal with provocative and perilous situations. This study sought to investigate corresponding self-control and self-control failures through the role of ego depletion in the decision to use force by police officers. Two experiments were conducted using officers from a German State Police force, requiring the participants to use force against a provocative role player. Experiment 1 found that the ego depletion measure failed and there were no differences between the groups. Using a different ego depletion method, experiment 2 found that ego-depleted participants aggressed earlier than controls. These results indicate that circumstances that produce ego depletion could lead to the inappropriate use of force through reducing self-control. This has major implications for the police use of force and how we understand police officers’ decision-making in response to provocation. 相似文献

This article uses recently declassified CIA documents to examine Soviet defectors of the 1950s, with a focus on US programs to court, receive, and utilize defectors against their homeland in espionage and psychological warfare operations. Eschewing the tendency at the time and in later scholarship to emphasize defectors’ ideological motivations, the piece argues that defectors often crossed over the Iron Curtain for reasons of self-preservation or self-advancement. Once in the West, defectors were mistrusted and badly assimilated into host societies. For these reasons, Soviet defectors rarely proved to be the committed anti-communists that American policy-makers expected them to be. 相似文献

The following article contrasts contemporary rosy periwinkle (Catharanthus roseus) extraction in southern Madagascar with original bioprospecting research conducted 50 years ago. My study shows how plant extraction firms have shifted their approaches by creating new labor forms, which devolve risk and increase exploitation in attempts to capture the valuable biogenetic material needed for drug discovery. The periwinkle symbolizes a complex picture of many dynamic barriers to capitalist penetration at work, including the natural, social and political. Over time, these barriers change and act in conjunction to provide a complex commodity chain expressing many exploitative labor relations of green capitalism. 相似文献
