We examined whether training in both the verbal and nonverbal indicators of truth telling and lying would have positive effects on Law Enforcement Officers’ (LEOs) ability to evaluate truths from lies. College course-level training on empirically validated verbal and nonverbal indicators of truth telling and lying was provided to mid- to advanced-career level LEOs, whose accuracy in detecting lies from truths was assessed pre- and post-training using truthful and deceptive videos of mock crimes and opinions. A marginally significant truth bias existed at pre-test; training, however, resulted in a significant improvement in accuracy rates for both truth and lie videos, and the truth bias that existed at pre-test was eliminated. Additional analyses indicated that accuracy rates improved for videos of mock crimes but not for opinions. These findings add to a small but growing literature that indicates that training on validated verbal and nonverbal indicators of truth telling and lying has positive benefits. 相似文献
The relatively weak quasi-experimental evaluation design of the original Boston Operation Ceasefire left some uncertainty about the size of the program’s effect on Boston gang violence in the 1990s and did not provide any direct evidence that Boston gangs subjected to the Ceasefire intervention actually changed their offending behaviors. Given the policy influence of the Boston Ceasefire experience, a closer examination of the intervention’s direct effects on street gang violence is needed.
Methods
A more rigorous quasi-experimental evaluation of a reconstituted Boston Ceasefire program used propensity score matching techniques to develop matched treatment gangs and comparison gangs. Growth-curve regression models were then used to estimate the impact of Ceasefire on gun violence trends for the treatment gangs relative to comparisons gangs.
Results
This quasi-experimental evaluation revealed that total shootings involving Boston gangs subjected to the Operation Ceasefire treatment were reduced by a statistically-significant 31 % when compared to total shootings involving matched comparison Boston gangs. Supplementary analyses found that the timing of gun violence reductions for treatment gangs followed the application of the Ceasefire treatment.
Conclusions
This evaluation provides some much needed evidence on street gang behavioral change that was lacking in the original Ceasefire evaluation. A growing body of scientific evidence suggests that jurisdictions should adopt focused deterrence strategies to control street gang violence problems. 相似文献
Apologizing is often seen as the appropriate response after a transgression for perpetrators. Yet, despite the positive effects that apologies elicit after situations of conflict, they are not always delivered easily. We argue that this is due—at least in part—to perpetrators overestimating the averseness of apologizing, thus committing a forecasting error. Across two laboratory experiments and one autobiographical recall study, we demonstrate that perpetrators overestimate the averseness they will experience when apologizing compared to the averseness they experience when they actually apologize. Moreover, we show that this effect is driven by a misconstrual of the effects of an apology. Perpetrators overestimate the potentially negative effects of apologizing while simultaneously underestimating the potentially positive effects of apologizing. This forecasting error may have a negative effect on the initiation of the reconciliation process, due to perpetrators believing that apologizing is more averse than it actually is. 相似文献
Criminal offending has many negative outcomes. Researchers have recently begun to consider the impact offending has on offenders' health, with a few studies focusing on differential mortality risk. Yet, prior research has been limited due to selective samples, restricted range of follow-up time period, limited set of explanatory variables, and lack of theoretical guidance. This paper examines the risk of early death among 411 South London males in the Cambridge Study in Delinquent Development followed into their late 50s. Attention is paid not only to differential risk of death between nonoffenders and offenders, but also to the risk within the population of offenders and through consideration of theoretical frameworks and associated predictor variables. Results show that high-rate chronic offenders evince the highest risk of death, an effect that continues even after controlling for childhood individual and environmental risk factors as well as participation in a range of analogous behaviors. 相似文献
This article examines how two of Japan’s largest newspapers frame death penalty issues. Through a content analysis of 7,153 Asahi and Nikkei articles in the 66-month period from January 1, 2007 to June 30, 2012, 11 death penalty frames are identified: inevitability, atonement by dying, atonement by living, victims’ rights and emotions, human rights, miscarriage of justice, calls for discussion, life without parole, deterrence, public support, and retribution. In addition to frames, we examined who the main voices are in each article on capital punishment. We found that avoidance and ambivalence are the two main approaches taken by Asahi and Nikkei to cover death penalty issues, and the most surprising finding is the high salience of atonement as a frame for thinking about capital punishment. In Japan, atonement is used to justify (atone by dying) and oppose (atone by living) the death penalty. Although atonement by living in prison and atonement by dying at the gallows imply radically different outcomes, the flexibility of the atonement frame may suggest new possibilities for Japan’s anti-death penalty movement. 相似文献
Citation analysis provides a quantitative means of tracking the most influential scholars and works within a field. Despite this advantage, there is a dearth of research that provides more than a snapshot of influence over a relatively short time period. One exception is the citation analysis body of research conducted by Cohn and Farrington (1990, 2012), which has recently been expanded to include European (Cohn and Iratzoqui 2016) and Asian (Farrington et al. 2019) criminologies. The current paper presents a thirty-year analysis (1986–2015) of scholarly influence within four international journals (Australian and New Zealand Journal of Criminology, British Journal of Criminology, Canadian Journal of Criminology and Criminal Justice, and Criminology), as well as an analysis of the Asian Journal of Criminology (AJC) over its first 10-year period (2006–2015). The main conclusions are that, while rankings over time are not generally consistent within journals, the most-cited scholars tend to remain highly ranked over time across the four main international journals. Furthermore, the most highly cited scholars in the four international journals were also highly cited in AJC. The most-cited works of the top scholars across all of the international journals, including AJC, covered four major areas, including developmental and life-course criminology, theoretical issues, statistics, and policy issues.
AbstractIn this essay we argue that changes in political structures in post-Soviet Ukraine have affected the potential for conflict during transition. Relying on organisational theory to determine the potential for conflict in Ukraine, we argue that this potential is structurally determined by the changing character of societal relations within and beyond Ukraine. The potential for conflict was always present in post-Soviet Ukraine, but this essay examines the facts of when, how and why conflict happened, and how it was related to weak state institutions, centre–periphery relations and an unsettled relationship with Russia. Relying on our analytical framework, we conclude that the conditions for further conflict greatly outweigh the conditions for peace. 相似文献
AbstractThe hope for a unique revolutionary actor in the twentieth century evaporated as a result of the weaknesses of social organisations. This paper examines the potential of an almost-forgotten group of revolutionary actors – collectively organised and deliberately involved in processes of social and productive transformation with a legitimate claim to territory – whose present-day activities involve them in concerted processes to consolidate a different constellation of societies on the margins of the global capitalist system. Indigenous and peasant communities throughout the Americas are self-consciously restructuring their organisations and governance structures, taking control of territories they claimed for generations. They are also reorganising production to generate surplus, assembling their members to take advantage of underutilised resources and peoples’ energies for improving their ability to raise living standards and assure environmental conservation and restoration. These communities are not operating in isolation. They coordinate activities, share information and build alliances. Hundreds of millions of people are participating in this growing movement; they occupy much more than one-quarter of the world’s land area. There is great potential for others to join them, expanding from the substantial areas where they are already operational. Global social networks are ensuring that this dynamic accelerates. 相似文献
