What are the effects of different elements of media on radicalization outcomes? A systematic review.

Background: Most national counter-radicalization strategies identify the media, and particularly the Internet as key sources of risk for radicalization. However, the magnitude of the relationships between different types of media usage and radicalization remains unknown. Additionally, whether Internet-related risk factors do indeed have greater impacts than other forms of media remain another unknown.

Police stops to reduce crime: A systematic review and meta-analysis.

Background: Police-initiated pedestrian stops have been one of the most widely used crime prevention tactics in modern policing. Proponents have long considered police stops to be an indispensable component of crime prevention efforts, with many holding them responsible for the significant reductions in violent crime observed across major US cities in recent decades. Critics, however, have taken issue with the overuse of pedestrian stops, linking them to worsening mental and physical health, attitudes toward the police, and elevated delinquent behavior for individuals directly subject to them.

Communities, Streets, and People: A Multi-level Study of the Correlates of Victimization.

The current study adds the context of the immediate microgeographic environment (measured as the street segment) to the study of individual victimization. Using residential survey and physical observation data collected on 449 street segments nested within 53 communities in Baltimore, MD, we employ multilevel logistic regression models to examine how individual risky lifestyles, the microgeographic context of the street, and community level measures influence self-reported property and violent crime victimization. Results confirm prior studies that show that risky lifestyles play a key role in understanding both property and violent crime victimization, and community indicators of disadvantage play a role in explaining violent crime victimization.

Reforming the police through procedural justice training: A multicity randomized trial at crime hot spots.

SignificanceOur study is a randomized trial in policing confirming that intensive training in procedural justice (PJ) can lead to more procedurally just behavior and less disrespectful treatment of people at high-crime places. The fact that the PJ intervention reduced arrests by police officers, positively influenced residents' perceptions of police harassment and violence, and also reduced crime provides important guidance for police reform in a period of strong criticism of policing. This randomized trial points to the potential for PJ training not simply to encourage fair and respectful policing but also to improve evaluations of the police and crime prevention effectiveness.

Effects of second responder programs on repeat incidents of family abuse: An updated systematic review and meta-analysis.

Background: Family abuse is a recurrent phenomenon within a select population of households. This form of abuse can include any physical or psychological harassment that occurs between family or household members, and often involves complex mental and emotional issues that are resistant to intervention. Traditional criminal justice strategies for combating this issue have evolved over time but have frequently demonstrated limited success.

Updated protocol: Effects of second responder programs on repeat incidents of family abuse: An updated systematic review and meta-analysis.

The US Department of Justice has extensively funded second responder programs. In England and Wales, funding of follow-up with victims is largely funded by local Police and Crime Commissioners. While these programs rapidly gained popularity in the United States and are gaining popularity in other countries as well, the evidence regarding their effectiveness is mixed.

Cognitive and behavioral radicalization: A systematic review of the putative risk and protective factors.

Background: Two of the most central questions in radicalization research are, (1) why do some individuals radicalize when most of those from the same groups or exposed to similar conditions do not? and (2) why do radicalized individuals turn to radical violence while the majority remain inert? It has been suggested that the answer to both questions lie in the cumulative and interactive effects of a range of risk factors. While risk assessment and counter-radicalization take a risk-protective factor approach, there is widespread debate as to what these factors are and which are most important.

Objectives: This review has two primary objectives.

PROTOCOL: What are the effects of different elements of media on radicalization outcomes? A systematic review.

Objectives: In this systematic review and meta analysis we will collate and synthesize the evidence on media-effects for radicalization, focusing on both cognitive and behavioral outcomes. The goal is to identify the relative magnitudes of the effects for different mediums, types of content, and elements of human-media relationships.

Methodology: Random-effects meta analysis will be used and the results will be rank-ordered according to the size of the pooled estimates for the different factors.

Enhancing Informal Social Controls to Reduce Crime: Evidence from a Study of Crime Hot Spots.

There is growing evidence that crime is strongly concentrated in micro-geographic hot spots, a fact that has led to the wide-scale use of hot spots policing programs. Such programs are ordinarily focused on deterrence due to police presence, or other law enforcement interventions at hot spots. However, preliminary basic research studies suggest that informal social controls may also be an important mechanism for crime reduction on high crime streets.

PROTOCOL: Cognitive and behavioral radicalization: A systematic review of the putative risk and protective factors.

Objectives: This systematic review seeks to collate and synthesize putative risk and protective factors for the different outcomes of radicalization.

Methodology: Drawing on an established theoretical framework, we will categorize putative risk and protective factors as they relate to the domains of radical attitudes, intentions, and behaviors. We will utilize meta-analytic techniques to develop a rank-order of factors according to effect size.

Does Collective Efficacy Matter at the Micro Geographic Level?: Findings from a Study Of Street Segments.

Many scholars argue that collective efficacy is not relevant to understanding crime at the microgeographic level. We examine variation in collective efficacy across streets with different levels of crime in Baltimore City, MD, and, then, employ multilevel modelling to assess this relationship. We find that people who live in crime hot spots have much lower levels of collective efficacy than people who live in non-hot spot streets and that this relationship persists when controlling for a large number of potential confounders both at the street and community levels.

Problem-oriented policing for reducing crime and disorder: An updated systematic review and meta-analysis.

Background: Herman Goldstein developed problem-oriented policing (POP) to focus police on more proactively addressing chronic problems, rather than using traditional reactive efforts. POP has been utilized to target a wide range of problems and has become commonly used in agencies across the United States and the world, although implementation is often uneven. POP interventions commonly use the SARA (scanning, analysis, response, assessment) model to identify problems, carefully analyze the conditions contributing to the problem, develop a tailored response to target these underlying factors, and evaluate outcome effectiveness.

Poor Health and Violent Crime Hot Spots: Mitigating the Undesirable Co-Occurrence Through Focused Place-Based Interventions.

Introduction: The geographic overlap of violence and poor health is a major public health concern. To understand whether and how place-based interventions targeting micro-geographic places can reduce this undesirable co-occurrence, the study addresses 2 important questions. First, to what extent are deteriorated health conditions associated with living at violent crime hot spots? Second, through what mechanisms can focused place-based interventions break the association between living with violence and deteriorated health?

Methods: This study used survey data from 2,724 respondents living on 328 street segments that were categorized as violent crime hot spots (181 segments with 1,532 respondents) versus non-hot spots (147 segments with 1,192 respondents) in 2013-2014 in Baltimore, Maryland.

Perspectives of people with mental health problems at hot spots: Attitudes and perceptions of safety, crime, and the police.

People who live in places with high levels of crime and disorder are more likely to experience mental illness compared with those who do not live in these types of place (Weisburd et al., 2018; Weisburd & White, 2019). The increased police presence on high crime streets may also increase the likelihood that these individuals will encounter law enforcement.

Hot Spots of Crime are Not Just Hot Spots of Crime: Examining Health Outcomes at Street Segments.

In this paper we seek to identify whether the relationship between health disparities and crime occurs at a micro geographic level. Do hot spot streets evidence much higher levels of mental and physical illness than streets with little crime? Are residents of crime hot spots more likely to have health problems that interfere with their normal daily activities? To answer these questions, we draw upon a large National Institutes of Health study of a sample of hot spots and non-hot spots in Baltimore, Maryland. This is the first study we know of to report on this relationship, and accordingly we present unique descriptive data.

Understanding the role of service providers, land use, and resident characteristics on the occurrence of mental health crisis calls to the police.

Similar to concentrations of crime, mental health calls have been found to concentrate at a small number of places, but few have considered the context of places where mental health calls occur. The current study examines the influence of the physical and social context of street segments, particularly the role of service providers, land use features of the street and nearby area, and characteristics of residents on the likelihood of a mental health crisis call to the police occurring on the street. The findings demonstrate that the social context, such as offending and drug use among residents, levels of social cohesion and community involvement, and drug and violent crime influenced the occurrence of mental health crisis calls.

Mean Streets and Mental Health: Depression and Post-Traumatic Stress Disorder at Crime Hot Spots.

This study explores the relationship between mental health and place at microgeographic units of analysis. We examine self-reported symptomology for depression and PTSD for 2,724 survey respondents interviewed in three types of randomly selected street segments: violent crime hot spots, cool spots, and cold spots. We find that the mean symptomology score is 61% higher for depression in violent crime hot spots than cold spots, and 85% higher for PTSD.

"The Whole Is Greater Than the Sum of the Parts": Prison Staff Perceptions of Domestic Violence Rehabilitation Programs.

This qualitative study is part of a mixed methods research project that examined the effectiveness of the primary rehabilitation program for domestic violence offenders in the Israeli Prison Services-the "House of Hope." The quantitative part of the study showed that the "House of Hope" program was effective in reducing recidivism among participating inmates. The purpose of this qualitative study was to describe the rehabilitation program according to the perspectives of the program staff.

Developmental trajectories of offenders convicted of fraud: A follow-up to age 50 in a Dutch conviction cohort.

This study describes the criminal careers of offenders convicted of fraud, distinguishing different career dimensions such as intermittency, versatility and specialization. Results indicate that most fraud offenders are versatile in the sense that they also have significant criminal records for other serious offending (that is, not fraud). At the same time they are also specialized in fraud.

Focused deterrence and the prevention of violent gun injuries: practice, theoretical principles, and scientific evidence.

Focused deterrence strategies are a relatively new addition to a growing portfolio of evidence-based violent gun injury prevention practices available to policy makers and practitioners. These strategies seek to change offender behavior by understanding the underlying violence-producing dynamics and conditions that sustain recurring violent gun injury problems and by implementing a blended strategy of law enforcement, community mobilization, and social service actions. Consistent with documented public health practice, the focused deterrence approach identifies underlying risk factors and causes of recurring violent gun injury problems, develops tailored responses to these underlying conditions, and measures the impact of implemented interventions.
