Testing a promising homicide reduction strategy: re-assessing the impact of the Indianapolis “pulling levers” intervention

Since the publication of analyses suggesting the significant impact on youth homicide of the Boston “pulling levers” intervention, a series of studies of similar strategies have indicated promise in reducing homicide and gun assaults. One of these studies was an assessment of a pulling levers strategy in Indianapolis, where trend analyses indicated a significant reduction in homicide following the intervention, while six other similar Midwestern cities did not experience a significant decline in homicide. We re-assess the results of the Indianapolis study by disaggregating the offenses into gang- and non-gang homicides. Given that the pulling levers program focused on influencing gangs and networks of chronic offenders, the impact of the intervention should be more apparent for gang homicides than for non-gang homicides. Alternatively, should the impact be similar for non-gang homicides, then it is more likely that the downward trend would be caused by unmeasured external forces. Coefficient-difference tests relying on estimates obtained from autoregressive integrated moving average (ARIMA) time–series models indicate that gang homicides declined significantly more than did non-gang homicides following the Indianapolis intervention. These findings suggest ‘something happened’ to gang homicides that did not happen to non-gang homicides, which adds further support that the pulling levers initiative was the driving force behind the overall reduction in homicide in Indianapolis.

The canary in the data mine

The present article aims at portraying the type of profile best required to fulfil the function of a Data Protection Officer (DPO) within the EU public sector. The article proposes the idiom of the “canary in a coal mine” as best positioned to describe the multidisciplinary role of DPOs. Due to the particularity and sensitivity of their function, Data Protection Officers act as early indicators of data protection incompliance within their respective area of expertise. Only when being functionally independent, Data Protection Officers could master the role of “canaries in the data mine” thus preventing possible data protection breaches and violations.     

Effectiveness of a risk–need–responsivity‐based treatment program for violent and sexual offenders: Results of a retrospective,quasi‐experimental study

Purpose

Relapse prevention is an important goal in correctional settings. Although there is strong evidence for the effectiveness of certain treatment programs for juvenile offenders, those for adults lack such evidence. This study evaluated the effectiveness of a risk–need–responsivity (RNR)‐based intervention.

Methods

A quasi‐experimental, observational study design and cox regression analysis were used to compare treated violent and sexual offenders (n = 171) with untreated offenders (n = 241).

Results

Both groups were observed for an average of 7.9 years. Recidivism rates of treated offenders (11.7%, n = 20) were similar to those of control offenders (15.8%, n = 38; p = .25). When controlling for confounding variables, the hazard of recidivism in the treatment group was 5.2% lower than that in the control group. Subdividing the treatment group resulted in lower hazard ratios for offenders still in therapy when released and offenders cancelling therapy. However, none of the group differences was statistically significant.

Conclusion

Our results show that control and RNR‐based treatment groups had comparable recidivism rates with a trend towards a positive treatment effect, especially for people in outpatient treatment. However, criminal history, age at the start of follow‐up, and actuarial risk of recidivism were significantly associated with recidivism. Future research needs to apply elaborate methodological approaches to detect robust treatment effects and consider different criteria of treatment effectiveness. Furthermore, the influence of prison climate, motivational factors, intervention quality, and factors supporting the success of outpatient treatment should be considered in future studies of larger offender samples.

改制上市不是灵丹妙药--由日本的教训看我国银行改革的制度缺陷与制度设计

目前,我国国有商业银行的改革进入到攻坚阶段,改制上市成为当前国有商业银行改革的目标和救命稻草。但日本银行业历经十年的改革,却仍未取得实质进展的教训提醒我们,仅仅实现形式上的产权多元化和上市并不能从根本上解决银行业的问题,关键是要吸取日本银行改革的教训,分析国有商业银行改革中存在哪些制度缺陷,然后标本兼治,大刀阔斧地进行一系列制度创新才能把国有商业银行打造成富有效率、规范运作的现代金融企业。

Modeling teachers acceptance of learning management system in higher education during COVID-19 pandemic: A developing country perspective

The ubiquity of the World Wide Web has provided massive opportunities to teachers and learners around the globe to share knowledge anytime anywhere via learning management system. Hence, considering the needs of the students; universities have arranged the facilities of the learning management system. This study is an empirical evaluation of university faculty members' intention to use a learning management system. We extended Davis's (1989) Technology Acceptance Model (TAM) to evaluate faculty members' intention to use learning management system amid COVID-19. Data were obtained from the faculty members of Pakistani universities through the convenience sampling technique and analyzed using PLS-SEM. The outcomes of the study revealed that perceived ease of using a learning management system, user-interface design, and faculty members' innovativeness have a favorable impact on their intention to use learning management system. Facilitating conditions positively influenced intention to use learning management system. However, the positive relationship between facilitating conditions and perceived ease of using the learning management system was insignificant. The results indicate that the extended TAM model has effectively predicted faculty members' intention to use the learning management system. The findings of the current study can be used for the training and development of faculty members by institutions and regulatory bodies in developing countries.
