Objectives
Our multisite randomized controlled trial reported that police body-worn cameras (BWCs) had, on average, no effect on recorded incidents of police use of force. In some sites, rates of use of force decreased and in others increased. We wanted to understand these counter-intuitive findings and report pre-specified subgroup analyses related to officers’ discretion on activating the BWCs.Methods
Using pre-established criteria for experimental protocol breakdown in terms of treatment integrity, ten experimental sites were subgrouped into “high-compliance” (no officer discretion applied to when and where BWCs should be used; n?=?3), “no-compliance” (treatment integrity failure in both treatment and control conditions; n?=?4), and tests where officers applied discretion during treatment group but followed protocol in control conditions only (n?=?4).Results
When officers complied with the experimental protocol and did not use discretion, use of force rates were 37 % lower [SMD?=?(?.346); SE?= .137; 95?% CI (?.614) – (?.077)]; when officers did not comply with treatment protocol (i.e., officers chose when to turn cameras on/off), use of force rates were 71 % higher [SMD?= .392; SE?= .130; 95?% CI (.136) – (.647)], compared to control conditions. When full discretion (i.e., overall breakdown of protocol) was applied to both treatment and control conditions, null effects were registered [SMD?= .009; SE=.070; 95?% CI (?.127) – (.146)], compared to control conditions.Conclusions
BWCs can reduce police use of force when then officers’ discretion to turn cameras on or off is minimized—in terms of both case types as well as individual incidents. BWCs ought to be switched on and the recording announced to suspects at early stages of police–public interactions. Future BWCs tests should pay close attention to adherence to experimental protocols.492.
This study conducted telephone interviews with a random sample of adults (N = 509) in a state with a universal child abuse reporting law. A substantial proportion of the interviewees (39%) were not aware of this law. Findings indicated that the public's understanding was mixed. Most respondents knew that reports could be made anonymously and that their identity could be kept private. However, most believed that children are automatically removed from the home if there is maltreatment and more than 50% were not aware they could be charged with a misdemeanor for failing to report a suspicion of child abuse. The respondents who had ever made a report (19%), had a greater knowledge of the laws than those who had not made a report. Older adults and those with less education had the least accurate perception of child abuse reporting policies. When asked about barriers to reporting, respondents cited worries that reporting would not help the child. Findings suggest that efforts to increase the public's comfort with reporting may require strategies to increase their confidence that the benefits will outweigh the risks for the child. 相似文献

In Kenya, as in many developing countries, centralized control over water resources was implemented to improve agricultural productivity. By the 1980s, however, Kenya's postindependence policies of bureaucratic control were in disarray, and conflicts over water use were common. More recently, Kenya has embarked on a series of reforms that create a polycentric approach to water governance, in which decision making about water resources is shared among multiple, overlapping local, regional, and national authorities. Drawing on archival and field research, we examine these reforms in their historic context and argue that whereas centralized control was poorly adapted to the Kenyan context, polycentric governance is better suited to Kenya's variable social and ecological conditions and the available resources of its administrative agencies. 相似文献

This study involves an evaluation of an innovative approach to the handling of domestic violence (DV) cases in the city of Cleveland, Ohio that includes (1) a DV Project composed of specially trained police detectives, prosecutors and victim advocates for investigating and prosecuting domestic violence cases involving adult female victims who are married to, cohabitating with, or have a child with the defendant; and (2) a Dedicated Domestic Violence Docket that involves two Municipal Court judges hearing all of the domestic violence cases that are handled by the DV Project. We collected data on six months of domestic violence cases occurring in the latter half of 2008 (N?=?1388), by linking records from the Cleveland Police Department, the Prosecutor’s Office, and the Municipal Court. We found that very few victims in police districts lacking the DV Project follow up with a prosecutor to pursue the case further, indicting that specialized DV units in police departments can have a significant impact on the number of DV cases that move forward through the criminal justice system. DV Project cases were slightly less likely to result in charges issued by prosecutors (OR?=?.499) but more likely to result in dismissals (OR?=?2.545) and referrals to DV treatment programs (χ2?=?3.88). 相似文献

Despite the apparent role alcohol plays in criminal offences, there is at present no evidence available as to the extent of the problem of intoxicated witnesses within England. To address this lack of research, police officers from seven constabularies completed an online survey addressing issues such as the prevalence of intoxicated witnesses, how officers determine intoxication, the procedures employed and their effectiveness. Officers indicated that intoxicated witnesses were a common, to very common, occurrence with most officers determining intoxication through physical symptoms and the witness’s own admission. In terms of interviewing witnesses, the majority of officers indicated that initial details were taken whilst witnesses were intoxicated, but the evidential interview was taken when sober. Officers also indicated that if the witness was intoxicated then the case was less likely to proceed to court and that officers viewed the witness as less accurate. These findings are considered from a criminal justice perspective and discussed in relation to future research. 相似文献

This paper presents findings from the first systematic appraisal of mainstream news reporting of the appointive government in Britain. Such a perspective is urgently needed in the light of the expanded role and influence of ‘Quasi‐Autonomous Non Governmental Organisations’ in public affairs. This paper provides an overview of long‐term trends in media reporting of general principles of quasi‐government and an examination of the routine coverage of public bodies that can be classified as quangos. These related exercises show that the ‘new managerialist’ ethos that fuelled the recent expansion of the appointive state finds little endorsement in general media discourses about the quango state, but is often implicitly reflected in journalists' treatment of specific organisations and their work.

Out-of-school suspension continues to disconnect an overwhelming number of economically disadvantaged ethnic minority (EDEM) youth from school—leading to out-of-school placement. Youth communities and localities may provide alternative spaces for suspended youth and create opportunities for prosocial engagement and support. The present study employed participant observation and interviews to explore suspended youth sense of social connectedness in a community-based intervention program in the United States. Findings illustrate psychosocial assets and youth sense of social connectedness emerged from relational bonds and a structural culture enforcing a nurturing and inclusive environment. A discussion on improving the capacity of community-based organizations to address the needs of suspended youth follows. 相似文献

The study considers the ‘Shared’ Workplace agenda in Northern Ireland, which is a significant aspect of the reconciliation process. Our emphasis is on the capacity of a wide group of work-based social identifications to affect, limit, and frustrate this policy. Specifically, we address the impact of spatial and functional factors as well as occupational and professional characteristics through fieldwork in three local authorities. Interviews were held with a cross section of 65 subjects, each of whom had either been employed by or worked in partnership with one of these authorities. Our study thus contrasts with much of the literature on Northern Ireland, which is concerned with the impact of Protestant/Catholic or Unionist/Nationalist identities on such reconciliation processes in the workplace and more widely. This approach enables us to develop insights about implementation of such agendas, specifically concerning Northern Ireland and other deeply divided societies. In the conclusion, connections are also made between our findings and consociational forms of governance. 相似文献

Recent evidence suggests parent-adolescent discrepancies regarding adolescent disclosure can provide insight into parent-child relations and adolescent adjustment. However, pathways linking discrepancies to adjustment are not well known. We tested a model linking parent-adolescent discrepancies in disclosure to adolescent substance use through affiliation with deviant peers. Using three annual waves of data from a community-based study (N?=?357; 91% African American; 53% female; Mage?=?13.13 years, SD?=?1.62 years at baseline), findings revealed that adolescent-reported secrecy and deviant peer affiliation were positively associated with substance use one and two years later, respectively, but there was no evidence of mediation. The results highlight associations of adolescent secrecy and adjustment, and the role peers play in adolescent substance use behaviors. 相似文献
