Crime is highly concentrated at places that lack capable place managers (i.e., landlords and their delegates). In response, numerous cities have instituted problem property interventions that pressure landowners to better manage properties suffering from decay, nuisance, or crime. This approach is distinctive in that it both targets a place and incentivizes those legally responsible to improve its management, yet little is known about the efficacy of such interventions. We assess the short- and long-term impacts of such interventions in Boston, Massachusetts, using matched difference-in-difference analyses. Problem property interventions reduced crime and disorder relative to comparable matched properties. They also led to property investment and landowner turnover, suggesting strengthened place management. In addition, drops in crime and disorder were observed at other properties on the same street, although not at other properties with the same owner throughout the city. This study, therefore, provides evidence that problem property interventions compel landowners to better manage the targeted property and that these effects have a diffusion of benefits on surrounding properties. The effect on place management, however, was limited to the target property and did not reliably generalize to the landowner's other holdings. This study reveals nuance in the ways that problem property interventions can benefit communities.

This review, published on the twenty-fifth anniversary of the publication of Code of the Street (1999), considers the legacies of Elijah Anderson's groundbreaking analysis of the interactional rules for negotiating street violence within the context of racism and structural disadvantage in Philadelphia. Empirical testing has yielded substantial support for Code of the Street’s key arguments. In the process of assessing its generalizability, such scholarship has inadvertently flattened and decontextualized the theory by, for example, reducing it to attitudinal scales. We identify a more politically conscious analysis in the original text than it is generally credited with, which we use to argue that “code of the street” has outgrown its reductive categorization as a subcultural theory. We conclude that the pressing issue of urban gun violence makes now an ideal time to refresh the theory by resituating it within the contemporary structural and cultural landscape of urban violence, analyzing the social-ecological features that shape the normative underpinnings of interpersonal violence, and studying the prosocial and adaptive features of the code.

The Offender Personality Disorder (OPD) Pathway programme is a jointly commissioned initiative between NHS England and Improvement and HM Prison & Probation Service aimed at supporting and managing offenders with complex mental health needs. The aim is to provide a network of psychologically informed services for high-risk high-harm offenders guided by detailed case formulation. The aim of this evaluation was to identify how the Pathway was being experienced by offenders within Pathway services and the staff involved in managing them since its implementation, to statistically compare outcomes between individuals referred to OPD services and those not referred, and to identify whether there was evidence of cost-effectiveness of the Pathway and how different elements of the Pathway contribute to cost-effectiveness. It should be noted that the aim of this evaluation was to look at the OPD Pathway as a whole, and was not to identify the contribution of the various OPD Pathway interventions.

This report presents the methodology and findings of an evaluation of the effectiveness of the Milwaukee Homicide Review Commission (MHRC), which was established in May 2004 with the mandate to address the city's persistent lethal violence.

A distinguishing feature of the MHRC is its inclusion of community agencies and leaders outside of the traditional criminal justice system. The evaluation examined MHRC's work from January 2005 through December 2007. Overall, the homicide review process found that homicide in the city's intervention districts were largely clustered in specific locations, such as in and around taverns, as well as in districts with concentrations of active offenders who had been involved in the criminal justice system. Homicides were often the outcome of persistent disputes between individuals and/or groups (usually gangs). Homicides were often committed to gain respect and status among peers who valued fearless displays of power and control over others, as well as to inflict retribution on those showing disrespect and confrontational interactions. Generally, the MHRC decision-making and actions produced a comprehensive set of actionable policy and practice recommendations whose implementation and effects were continuously monitored by the MHRC. MHRC actions were intended to better position criminal justice, social service, and community based organizations in addressing the violence-related factors in high-risk locations and high-risk individuals with a propensity for violence. The impact evaluation found that the implementation of the MHRC interventions was linked with a statistically significant 52-percent decrease in the monthly count of homicides in the treatment districts. In comparison, the control districts had a statistically insignificant 9.2- percent decrease in homicides, after controlling for the other covariates. Apparently, the MHRC's crafting of interventions designed to address underlying risks associated with homicides has had a significant impact in reducing incidents of lethal violence.

This book considers how the concept of violence has been interpreted, used, defined, and explored by social researchers and thinkers. It does not provide a final answer to the question of what violence is or how it should be explained (or prevented), and instead offers a variety of useful ways of thinking about and theorising the phenomenon, mainly from a sociological standpoint. It outlines four ways of understanding violence: • Violence as situation: the tension that exists between category-driven and situational explanations. • Violence as speciality: the study of particularly violent actors, and how they may be understood by reference to childhood histories, technologies, institutions, culture, class, and gender. • Violence as politics: political violence and violent politics. • Violence as storytelling: representations of violence from a narrative perspective. Concluding with reflections on possible convergences between the four approaches and new directions for research, this book offers a unique and experimental approach to discussing and reconstructing the concept of violence.

During early childhood, children develop cognitive and socioemotional skills that predict success in multiple socioeconomic dimensions. A large part of the development of these skills depends on the child’s context during the first years of life and, in particular, on the quality of parental care. Grounded on recent literature in psychology and behavioral economics, we discuss a theoretical framework for understanding why some children receive adequate care, while others do not. Within this framework, we identify a determinant of the quality of parenting that has not yet been explored in-depth: the availability of parents’ mental resources, which are depleted by the subjective feeling of scarcity and the stress generated by adversities. Using cross-sectional data from a household survey in Colombia and administrative data on crime and violence, we find that a greater subjective feeling of scarcity (β=0.45, IC95%:[0.082, 0.979]) and greater exposure to violence (β =0.09, IC90%:[0.004, 0.182]) are associated with a lower likelihood that parents engage in stimulating activities with their children. At the same time, the results show that receiving information on childrearing is correlated with better parental practices (β =-0.48, IC95%:[-0.822, -0.136]).

The relationship between income inequality and crime has attracted the interest of many researchers, but little convincing evidence exists on the causal effect of inequality on crime in developing countries. This paper estimates this effect in a unique context: Mexico's Drug War. The analysis takes advantage of a unique data set containing inequality and crime statistics for more than 2,000 Mexican municipalities covering a period of 20 years. Using an instrumental variable for inequality that tackles problems of reverse causality and omitted variable bias, this paper finds that an increment of one point in the Gini coefficient translates into an increase of more than 10 drug-related homicides per 100,000 inhabitants between 2006 and 2010. There are no significant effects before 2005. The fact that the effect was found during Mexico's Drug War and not before is likely because the cost of crime decreased with the proliferation of gangs (facilitating access to knowledge and logistics, lowering the marginal cost of criminal behavior), which, combined with rising inequality, increased the expected net benefit from criminal acts after 2005.

What’s the issue? After fifteen years of failed security policies, the government of El Salvador is in the middle of an open confrontation. Efforts aimed at fighting gangs’ deep social roots have not produced desired results due to a lack of political commitment and social divisions that gangs use to their advantage. Why does it matter? Born in the wake of U.S. deportation policies in the late 90s, gang violence in El Salvador has developed into a national security problem that accounts for the country’s sky-high murder rate. The combination of mano dura (iron fist) policies and the U.S. administration’s approach to migration could worsen El Salvador’s already critical security situation. What should be done? All political actors should honour the government’s holistic violence prevention strategies by fully implementing them and reframing anti-gang policies. Specific police and justice reforms, as well as a legal framework for rehabilitating

What’s new? Violence, coca production and drug trafficking have spiked along Colombia’s Pacific coast since the 2016 peace agreement between the government and FARC guerrillas. New and old armed groups battle for control over communities, territory and illegal business, triggering ongoing displacement and low-intensity warfare. Why does it matter? Long one of Colombia’s poorest and most peripheral regions, the Pacific’s struggles highlight huge difficulties in improving security without addressing economic and political roots of armed group recruitment and the co-option of communities by organised crime. What should be done? Instead of depending on a counter-insurgency strategy or a “kill/capture” policy to dismantle armed groups, the Colombian government should prioritise building a stable, trustworthy civilian police and state presence, demobilising combatants, fulfilling its peace accord promises on local development and coca substitution, and furnishing educational opportunities for local people.

What’s new? The COVID-19 pandemic had an immediate impact on organised crime across Mexico and Central America’s northern countries as lockdowns slowed movement of people and goods. But criminal groups swiftly adapted to the new normal, using it to tighten or expand their control over people and territory. Why does it matter? The region’s criminal groups, many acting in collusion with rogue state actors, are largely responsible for some of the world’s highest murder rates and wield asphyxiating power in an increasing number of communities. With state budgets under huge strain, official responses are set to remain lacklustre. What should be done? Governments should combine policing to contain and deter crime with increased support to the most insecure areas and vulnerable populations. Rather than reverting to heavy-handed tactics, they should invest in programs that reduce impunity and create economic alternatives for at-risk young people, potentially with the help of COVID-19 emergency funds.

This vintage text, first published in 1978, on the causes, consequences and distribution of violence is as relevant today as it was over 4 decades ago.. Though limited to research of the 1970s, the explanations, exposition and reviews of data and theories of violence are staggeringly similar to the research of the 21st century. The organization of the material is unequaled, and will help any student of violence, or anyone who seeks answers and understanding, with its well organized exposition and clear, down-to-earth style. The new preface by the author identifies what he would add if he were doing a new edition, and why in the end he chose not to write one.

How to Make a Human: Animals and Violence in the Middle Ages tracks human attempts to cordon humans off from other life through a wide range of medieval texts and practices, including encyclopedias, dietary guides, resurrection doctrine, cannibal narrative, butchery law, boar-hunting, and teratology. Karl Steel argues that the human subjugation of animals played an essential role in the medieval concept of the human. In their works and habits, humans tried to distinguish themselves from other animals by claiming that humans alone among worldly creatures possess language, reason, culture, and, above all, an immortal soul and resurrectable body. Humans convinced themselves of this difference by observing that animals routinely suffer degradation at the hands of humans. Since the categories of human and animal were both a retroactive and relative effect of domination, no human could forgo his human privileges without abandoning himself.Medieval arguments for both human particularity and the unique sanctity of human life have persisted into the modern age despite the insights of Darwin. How to Make a Human joins with other works in critical animal theory to unsettle human pretensions in the hopes of training humans to cease to project, and to defend, their human selves against other animals.

How is it foun so fond a feeling may grow so cruel and lead to commission of so many barbarous murders…?”

Most psychological studies report a positive relationship between violent video game play and aggression. In line with that researchers and policy makers alike understand playing violent video games as contributing factors to increased aggression in teenagers and young adults including, perhaps, high school shootings. However, laboratory studies are unable to account for either the possible selection of relatively violent people into playing violent video games or foregone aggressive effects of alternative activities video game playing may substitute for. Specifically, psychological laboratory experiments cannot address the time use effects of video games which tend to incapacitate gamers from violent activity, e. g. crimes, by drawing them into extended gameplay. Accordingly, laboratory studies may be poor predictors of the net effects of violent video games on society, thus potentially overstating the importance of video game induced aggression. We argue that as both a behavioral tendency toward aggression and incapacitation from aggression are consequences of playing violent video games, the policy relevance of violent video game regulation depends critically on the degree to which one outweighs the other. We empirically investigate how video games could affect crime using four years of weekly data from the US by matching four different data sources. The number of violent and nonviolent crime incidents each week we obtain from the National Incident Based Reporting System (NIBRS). Our measure for video game play is derived from VGChartz which report the unit sales of the top 50 video games across the US each week. To determine the violent content of each game, we collect information from the Entertainment Software Rating Board (ESRB). This nonprofit body rates the appropriateness of games and provides detailed content descriptions for each game including the degree of violence. To control for unobserved factors that might influence both crime rates and video game play like, e. g., bad weather such as rain or heavy snow, we focus only on changes in game sales associated with differences in game quality as measured by Gamespot, a professional video game rating board (instrumental variable approach). Our results indicate two opposing effects. They suggest the behavioral effects in line with the psychological studies. If not for the incapacitation effect, violent video games would be associated with more violent crimes. However, the results also support a voluntary incapacitation effect in which playing either violent or non-violent games decrease crimes. Sales of either violent or non-violent games are associated with decreased violent and non-violent crime. The incapacitation effect dominates the behavioral effect such that, overall, violent video games lead to decreases in violent crime.

This paper studies the effects of the introduction of a new mass medium on criminal activity in Germany. The paper asks the question of whether highspeed internet leads to higher/lower sex crime offences and murder. I use unique German data on criminal offences and broadband internet measured at the municipality level to shed light on the question. In order to address endogeneity in broadband internet availability, I follow Falck et al. (2014) and exploit technical peculiarities at the regional level that determine the roll-out of high-speed internet. In contrast to findings for Norway (Bhuller et al., 2013), this paper documents a substitution effect of internet and child sex abuse and no effect on rape incidences. The effects on murder increase under the instrumental variable approach however remain insignificant. Overall, the estimated net effects might stem from indirect effects related to differences in reporting crime, a matching effect, and a direct effect of higher and more intensive exposure to extreme and violent media consumption. After investigating the potential channel, I do find some evidence in favor of a reporting effect suggesting that the direct consumption effect is even stronger. Further investigation of the development of illegal pornographic material suggests that the direct consumption channel does play a significant role in explaining the substitution effect.

Dominant scholarly approaches to drug trafficking violence (DTV) in Mexico generally explain its onset and escalation by focusing on one of four issues: a) the democratisation process in the 1990s and 2000s; b) the systemic corruption of the judicial and legislative institutions; c) a weak rule of law across the country; and d) the ‘war on drugs’ launched by former president Felipe Calderón (2006-2012). These approaches, however, fail to account for the discursive conditions that enable the perpetrators to engage in DTV. This thesis, therefore, proposes a new critical approach to our understanding of DTV by examining the life stories of thirty-three former narcos collected in Mexico between October 2014 and January 2015. Using a discourse analytical approach, I identify a set of meaning production regularities, uncovered through detailed interviews, which I conceptualise as narco discourse. In this discourse, informed by a neoliberal ethos, poverty is understood as a fixed condition, ‘poor people have no future’ and have ‘nothing to lose’. Under this logic, the ‘only’ way for them to enjoy life is to engage in illegal activities conceived as ‘la vida fácil’ [the easy life] which guarantee them ‘dinero fácil’ [easy money]. The narco discourse also produces the idea that ‘un hombre de verdad’ [a true man] embodies the normative characteristics of machismo. This masculinity, in turn, justifies male violence as ‘necessary’ in order to ‘survive’ in contexts of poverty. These three intertwined discourses of poverty, masculinity and violence enable the construction of DTV in instrumental terms, e.g. as ‘un negocio’ [a business’], as something ‘exciting’ and even as a source of empowerment. In this way, I demonstrate how DTV is discursively made possible by and for former narcos. This is a starting point for rethinking DTV not only as the result of corruption, or failed policies, but also as the product of the interplay between pre-existing social conditions and discourses produced and reproduced by perpetrators of DTV.

Most of the academic literature on violence in Nigeria is qualitative. It rarely relies on quantitative data because police crime statistics are not reliable, or not available, or not even published. Moreover, the training of Nigerian social scientists often focuses on qualitative, cultural, and political issues. There is thus a need to bridge the qualitative and quantitative approaches of conflict studies.This book represents an innovation and fills a gap in this regard. It is the first to introduce a discussion on such issues in a coherent manner, relying on a database that fills the lacunae in data from the security forces. The authors underline the necessity of a trend analysis to decipher the patterns and the complexity of violence in very different fields: from oil production to cattle breeding, radical Islam to motor accidents, land conflicts to witchcraft, and so on. In addition, they argue for empirical investigation and a complementary approach using both qualitative and quantitative data. The book is therefore organized into two parts, with a focus first on statistical studies, then on fieldwork.
