ABSTRACT

Police agencies have adopted social media quite widely, but researchers have paid relatively little attention to the phenomenon. To date few studies have explored public reaction to police use of social media. The current study uses a purposive sample with 7,116 police Facebook posts collected from 14 different police agencies during a one-year period to answer two principal research questions: (1) with respect to the number of likes, number of shares, or number of comments regarding different themes present in police Facebook posts, are there differences among police agencies corresponding to differences in the thematic content in their postings? and (2) What factors are related to the public reaction (i.e., likes, shares, comments) to a police Facebook post? The findings from ANOVA and negative binomial regression models clearly indicate that citizens do have definite preferences on police Facebook posts – they are more likely to like and make comments on posts of police personnel and police-public relations, but less likely to share posts of Social Networking Sites. Also, they are more prone to like posts with narratives and pictures, but less likely to favor posts containing hyperlinks. Policy implications and practice guidelines, study limitations, and future research are also discussed.  相似文献

ABSTRACT

Translational criminology is a decision-making perspective that emphasizes the dynamic coproduction of evidence by researchers and practitioners, focusing on obstacles to and facilitators of evidence generation and utilization. It incorporates several other data-driven decision-making models, including evidence-based policy making. This review suggests that the availability of empirical research is no longer the most significant impediment to evidence-based policing. Rather, translating and implementing knowledge about ‘what works‘ in policing has arisen as the field’s primary barrier to securing the effectiveness and efficiency improvements of research and data utilization. This article orients readers to translational criminology’s various components and explores their applications. Focusing on four central considerations, this review explores the roles of researcher practitioner partnerships, policy, technology, and government in developing and sustaining translational efforts in policing. The review concludes by acknowledging challenges to fostering a translational perspective in policing, and offers examples of where it has been applied with success.  相似文献

ABSTRACT

This article investigates the role of crime scene technicians in the Swedish criminal justice system, and particularly how Swedish crime scene technicians not only examine crime scenes but also facilitate the criminal justice system’s joint production of forensic evidence. It proposes thinking about the criminal justice system as a conglomeration of epistemic cultures, that is, of communities with different ways of producing and understanding forensic evidence. Such a perspective makes it possible to understand interprofessional frictions as epistemic frictions as well as to draw attention to the facilitations, mediations and translations that crime scene technicians perform. This perspective also makes it possible to illuminate how the crime scene technicians’ professionalization – a professionalization from the outside – affects both their future crime scene work and their facilitations.  相似文献

Forensic Technicians provide crime scene investigation services and are exposed to stressful violent crimes, motor vehicle accidents, biological or chemical hazards, and other appalling imagery. Forensic Technicians would likely experience physical and psychological stress after exposure to trauma, and security vulnerabilities similar to Sworn Police Officers. The perceived availability of mental health resources, job-related physical, psychological stress, and traumatic experiences of both Forensic Technicians and Sworn Police Officers from California law enforcement agencies were investigated using a self-reported survey. Responses were evaluated for any significant differences in the perceived stress, job-related physical stress, and resulting psychological impact affecting the participants. The survey contained a mix of True/False, Circle/Check the Appropriate Box, or Likert Scale (1–5) responses. The results were evaluated statistically and discussed. Results indicated Sworn Police Officers and Forensic Technicians have different on-duty stress levels, but similar off-duty stress levels. Nearly two-thirds of 54 job-related stressors were not significantly different between the two occupations. However, Forensic Technicians reported more adverse effects in 17 physical and psychological job-related activities compared with Sworn Police Officers. Forensic Technicians reported lower awareness levels and availability of agency mental health support services than were reported by Sworn Police Officers. This study reports for the first time an unexpected outcome that perceived and job-related psychological stress is greater for Forensic Technicians than Sworn Police Officers. Possible reasons for this disparity will be discussed as well as stress management tools that should be implemented to reduce health risk factors for both career professionals as well as increase public safety.  相似文献

Questions about when it is right for police forces to investigate alleged offences committed in the more or less distant past have become increasingly pressing. Recent widely publicized cases of child sexual abuse (CSA) and exploitation, sometimes involving high profile individuals, have illustrated the ethical, psychological, and forensic complexities of investigating non-recent child sexual abuse. Hannah Maslen and Colin Paine have developed the Oxford CSA Framework to assist police to weigh the various ethical considerations that militate for and against initiating a CSA investigation. While such a tool is to be welcomed, and while there is much that is helpful in Maslen and Paine's approach, we suggest that the Oxford CSA framework could be strengthened. Our first suggestion is to abandon a proposed distinction between a set of considerations that is said to generate a “presumption” in favor of investigation and other considerations that may supplement or oppose this presumption. Our second suggestion is to review the weightings applied to the considerations within the model, which lack clear justification and create problematic effects. Finally, we suggest that referring the Oxford CSA Framework to a panel with lived and professional experience of CSA could serve important procedural justice goals and enhance the Framework's recommendations.  相似文献

为调查公安院校大学生自我效能感与职业认同现状并探讨其相关性,通过整群抽样法选取某公安院校3280名大学生,采用一般自我效能感量表和警察职业认同量表进行调查,结果显示:该公安院校大学生的一般自我效能感总分为(26.49±5.72)分,职业认同总分为(11.55±1.64)分;单因素分析显示,自我效能感总分、职业认同总分在不同性别、就读层次、年级、是否为独生子女、是否为团员、是否自愿报考公安院校上有差异(p<0.05),且差异有统计学意义。另外,多因素回归分析显示,一般自我效能感是职业认同的影响因素(p<0.05)。研究结果表明该公安院校大学生的一般自我效能感及警察职业认同均处于中等偏上水平,且两者呈正相关性。建议增强公安院校大学生的自我效能感有助于提升其职业认同感。  相似文献

ABSTRACT

Rapid urbanisation in the global South has prompted attention to the causes and dynamics of urban violence. Yet, much research tends to either analyse urban violence without attention to the broader conflict complexes of which it forms a part, neglecting linkages between different forms of urban violence and between urban and rural dynamics, or conversely study violence in cities without acknowledging the particularities of the urban context. In this article, we conceptualise urban violence, theorise how it is shaped by urban dynamics and explore its manifestations in Nairobi, Kenya. We find that while Nairobi is not uniquely violent inside Kenya, violence takes on distinct urban forms given city-level processes, and also that urban violence has led to policies that increase securitisation and militarisation of the city. Our analysis thus improves knowledge of how criminal and political violence is shaped by and shapes the stability of developing cities.  相似文献
