Busy Streets Theory: The Effects of Community‐engaged Greening on Violence

Lack of maintenance on vacant neighborhood lots is associated with higher levels of depression, anxiety, and stress for nearby residents. Overgrown grasses and dense brush provide hiding spots for criminals and space to conduct illicit activities. This study builds upon previous research by investigating greening programs that engage community members to conduct routine maintenance on vacant lots within their neighborhoods. The Clean & Green program is a community‐based solution that facilitates resident‐driven routine maintenance of vacant lots in a midsized, Midwestern city. We use mixed effects regression to compare assault and violent crime counts on streets where vacant lot(s) are maintained by community members (N = 216) versus streets where vacant lots were left alone (N = 446) over a 5‐year timeframe (2009–2013). Street segments with vacant lots maintained through the Clean & Green program had nearly 40% fewer assaults and violent crimes than street segments with vacant, abandoned lots, which held across 4 years with a large sample and efforts to test counterfactual explanations. Community‐engaged greening programs may not only provide a solution to vacant lot maintenance, but also work as a crime prevention or reduction strategy. Engaging the community to maintain vacant lots in their neighborhood reduces costs and may increase the sustainability of the program.     

Childhood Trauma,Criminogenic Social Schemas,and Violent Crime

ABSTRACT

Utilizing a sample of 400 homeless street youth, the study draws on the social schematic theory of crime to examine if childhood trauma (physical abuse, physical neglect, emotional neglect, and sexual abuse) is linked to the development of a criminogenic knowledge structure (CKS) that mediates its relationship with violence. Results indicate childhood trauma is directly associated with the CKS. They also show that it is indirectly related through violent peers. The CKS in turn is directly linked to violence as are childhood trauma and violent peers. The CKS also mediates the relationship childhood trauma and violent peers have with violence. Violent peers likewise mediate the association between childhood trauma and violence. The link between childhood trauma and violence is also serially mediated through violent peers and the CKS. Findings suggest the social schematic theory offers a valuable explanation for the link between childhood trauma and violence.     

Personality,Parental, and Media Influences on Aggressive Personality and Violent Crime in Young Adults

Debate remains regarding the interaction between predictor variables for aggression, including family environment, media violence, and personality. The current study examined the contributions of gender and personality, exposure to physical abuse and violence in the family, and exposure to media violence in both television and in video games on violent criminal activity. Data from young adults (n = 355) indicated that personality characteristics and direct physical abuse significantly predicted violent crime. Exposure to television and video game violence were not significant predictors of violent crime. These results elucidate the complex interplay between multiple factors related to the etiology of violent crime. These results also call into question the belief that media violence is involved in the etiology of violent crime.     

The link between mental health,crime and violence

Research investigating the link between mental health, crime and violence often rely on populations that are at a high-risk of violent and criminal behaviour, such as prison inmates and psychiatric patients. As a result of this selection bias, the relationship between mental health, criminal and violent behaviour is significantly over-estimated, with mental health being incorrectly linked with violent and criminal behaviours. This study examines the relationship between mental health, violence and crime in a more representative community-based sample. One hundred and twenty-one individuals with and without a mental health disorder reported their involvement in crime and completed an aggression questionnaire. The results revealed that there is no statistically significant difference in terms of violence and crime involvement between individuals with a mental health diagnosis and those without. Moreover, the study did not find any statistically significant associations between specific mental health disorders and specific crime offences. The findings suggest that certain mental health disorders do not strongly contribute to crime violence and involvement. Limitations and implications are discussed in detail.     

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. Overall, we estimate that 14.8% of residents of violent crime hot spots meet thresholds for moderate depression or a diagnosis of PTSD. This can be compared to only 6.5% of residents at the cold spots. Using PSM and weighted negative binomial regression approaches we show that observable selection factors are not responsible for the relationships identified. Examining geographic influences, we find an important area effect of violent crime for both mental health measures, and an additional impact of the specific street of residence for PTSD.     

Homelessness, Mental Illness, and Criminal Activity: Examining Patterns Over Time

This study examined whether street homelessness, sheltered homelessness, and the severity of psychological symptoms predicted non-violent and violent crime among 207 mentally ill participants who were homeless at baseline. Participants were interviewed at 9 time points over 4 years. Hierarchical linear modeling (HLM) was used to examine whether changes in homelessness status and symptom severity predicted changes in criminal activity over time. Results indicated that homelessness both on the streets and in shelters and psychological symptom severity predicted increases in non-violent crime. Sheltered homelessness and symptom severity predicted increases in violent crime, although street homelessness did not. A separate mediational analysis with 181 participants showed that the relationship between diagnosis of a psychotic disorder and both non-violent and violent criminal activity was partially mediated through the severity of psychotic symptoms. Implications for research and intervention are discussed.     

The Mediating Role of Street Code Attitudes on the Self-Control and Crime Relationship

Research has demonstrated strong but independent attention to the role of self-control and street code attitudes in predicting criminal and violent behavior. Yet, there are good theoretical notions to believe that street code attitudes may be a salient mechanism in the self-control–offending relationship. Specifically, the present study investigates: (1) the extent to which self-control predicts adopting street code attitudes and (2) whether street code attitudes mediate the effect of self-control on criminal behavior. Using data collected from a multisite sample of over 900 young adults, we assess this mediation hypothesis for three distinct types of criminal activity: violent, property, and drug use. Our results reveal that individuals with lower self-control are more likely to adopt street code attitudes, that self-control is related to all three forms of offending, and that street code attitudes fully mediate the effect of self-control on violence, partially on property crime, but not in the case of drug use. Findings and directions for future research are discussed.     

The causes and costs of crime and a controversial cure

In spite of recent modest decreases, the epidemic of crime that began in the United States in the early 1960s has left us with a rate of violent crime that is still some 300% higher than it was 40 years ago. The usual suspects--poverty, the easy availability of street drugs and handguns, violent television programs--cannot account for this ominous trend. The fact that African Americans are responsible for nearly half of this violence, although they constitute only about one-eighth of the U.S. population, is the principal reason why the great improvement in race relations made over the past half-century has reached an asymptote. White fears, and Black resentment of these fears, are a grave threat to further progress. It is argued here that the main reason for this epidemic of crime and violence is the rapid recent increase in the proportion of the young people aged 15 to 24 who have grown up unsocialized. It is argued further that most of these feral youngsters are sociopaths, defined as genetically normal children whose failure of socialization was due to their being domiciled with an immature, overburdened, unsocialized, or otherwise incompetent parent or parents.     

Street Youths′ Fear of Violent Crime

Utilizing a sample of 300 street youths the article examines the roles, perceptions of control, depression, prior victimization, criminal behavior, peer crime and victimization, homelessness, and violent subcultural values play in the perception of violent victimization risk and the fear of violent crime. Results suggest that previous victimization and peers’ victimization along with depression and an external locus of control increases perceptions of victimization risk for violent crime. Younger street youths also perceived greater victimization risk. Further, females and minority respondents have higher levels of fear of violent victimization. Levels of fear of violent crime are also predicted by previous violent victimization, depression, and an external locus of control. In contrast, social support and violent subcultural values were associated with lower levels of fear. Findings are discussed in terms of extending theory to help understand perceptions of victimization risk and fear of crime.     

A longitudinal examination of the relation between co‐offending with violent accomplices and violent crime

Although the idea that youthful offenders are affected by the company they keep is widely accepted, evidence in support of this idea is based primarily on reports provided by offenders and their peers. As an alternative to relying on reports of criminal behavior, a method that may overestimate the role that peers play in criminal behavior, the current research on co‐offending uses court records to identify and track over time individuals who are known to commit crimes together. The present investigation is the first co‐offending study to track patterns of violent criminal behavior (over an 18‐year period) among a sample of urban offenders and their accomplices. The study tests whether violence “spreads” from violent offenders to those inexperienced in violence. Results indicate that nonviolent offenders who commit their first co‐offense with violent accomplices are at increased risk for subsequent serious violent crime. Findings suggest that lessons of violence can be learned “on the street,” where knowledge is passed along through impromptu social contexts, including those in which offenders commit crimes together.

Neighborhood violent crime and adolescent relationship aggression

Research has shown that neighborhoods play a role in the etiology of violence. However, few adolescent relationship aggression (ARA) studies have objective measures of violent neighborhoods. Drawing on a nationally representative sample of youth, this study examines the association between ARA and local levels of violent crime (measured using geocoded Uniform Crime Report data from each of the youths’ residential neighborhoods). Study analyses are based on survey data from 723 youth (ages 10–18) in current or recent dating relationships (351 males and 372 females) in the Survey on Teen Relationships and Intimate Violence (STRiV), a national representative household panel survey exploring interpersonal violence and related aggression among adolescents. About 19% of the sample reported ARA victimization in their most recent dating relationship (ARA perpetration was 17%). Neighborhood violent crime in the study (males living in 86.9 and females 99.8) was slightly lower than the national average of 100. With a broad national sample, 40% non-Whites, hypotheses guided by theories of neighborhood influence were tested. The study did not find an association between neighborhood violent crime and ARA victimization and perpetration, controlling for key demographic factors. The results, for a broad range of high- and low-crime neighborhoods, suggest that neighborhood violence does not seem to affect individual rates of ARA. The results suggest the ARA victimization and perpetration are perhaps ubiquitous and found both in low and high violent crime neighborhoods, suggesting that addressing local violent crime rates alone does not seem to be a path to also reducing ARA.     

Substance use patterns of young offenders and violent crime

The use of alcohol is a significant predictor of the involvement of young offenders in violent crime. This study found that in a sample of 300 incarcerated juveniles in New South Wales, more than 70% admitted to violent crime. Detainees from an Aboriginal or Torres Strait Islander culture were less likely than other detainees to be involved in violent crime. The substances most associated with violent crime were alcohol, followed by cocaine. However, when the likelihood that the young person has initiated violence as a response to alcohol or other substances is introduced into the equation, the direct effects for alcohol and cocaine predicting engagement in violent crime disappear. The Goldstein hypothesis that the effects of a substance directly facilitate violence, thereby accounting for the relationship between substances of use and violent crime, was supported. Aggr.

Churches as Neighborhood Organizations and Their Relationship to Street and Domestic Violent Crime: The Role of Denomination,Stability, and Heterogeneity

Recent developments in both theory and research on neighborhood crime have focused attention on the role of organizations. The current research builds on the existing literature to examine the relationship of churches to neighborhood “street” and domestic violence. The findings suggest that churches are fairly stable neighborhood organizations and not importantly heterogeneous, and neither factor appears to be related to neighborhood crime. Alternatively, the number of churches in a neighborhood is positively related to both street crimes and domestic assaults, and denomination does play an important role especially as it relates to domestic assaults. Theoretical and empirical implications are discussed.     

Sweetened blood cools hot tempers: physiological self-control and aggression

Aggressive and violent behaviors are restrained by self-control. Self-control consumes a lot of glucose in the brain, suggesting that low glucose and poor glucose metabolism are linked to aggression and violence. Four studies tested this hypothesis. Study 1 found that participants who consumed a glucose beverage behaved less aggressively than did participants who consumed a placebo beverage. Study 2 found an indirect relationship between diabetes (a disorder marked by low glucose levels and poor glucose metabolism) and aggressiveness through low self-control. Study 3 found that states with high diabetes rates also had high violent crime rates. Study 4 found that countries with high rates of glucose-6-phosphate dehydrogenase deficiency (a metabolic disorder related to low glucose levels) also had higher killings rates, both war related and non-war related. All four studies suggest that a spoonful of sugar helps aggressive and violent behaviors go down.     

Mental Disorders,Personality Traits,and Grievance-Fueled Targeted Violence: The Evidence Base and Implications for Research and Practice

This article aims to move away from intuitive appeals that link mental disorder with violence such as terrorism, mass murder, and other targeted violence. The article synthesizes the existing evidence base regarding the relationship between mental disorders and personality traits and (a) attitudinal affinities with violent causes, and (b) a number of violent behaviors (including mass murder and terrorism). The evidence base is mixed and the research focus changed across time: from simple and unempirical assertions of causation to an almost complete rejection of their presence to a finer grained and disaggregated understanding. Empirical research examining mental disorder in crime and violence highlights that the commission of such events is a complex synthesis of psychopathology, personal circumstance, and environment. The article concludes with several suggestions regarding future research and practice.     

Beyond Cultivation: Exploring the Effects of Frequency,Recency, and Vivid Autobiographical Memories for Violent Media

Using Shrum's (1996) heuristic processing model as an explanatory mechanism, we propose that people who hold vivid autobiographical memories for a specific past experience with media violence will overstate the prevalence of real-world crime versus individuals without vivid memories. We also explore the effects of frequency and recency on social reality beliefs. A survey was administered to 207 undergraduate students who were asked to recall one violent television program or movie seen in the past. Participants were asked to write essays describing the violence, which were coded for vividness. Results support not only cultivation theory, but also the effects of memory vividness: participants with more vivid memories of blood and gore gave higher prevalence estimates of real-world crime and violence than participants with less vivid memories. Findings also suggest that females had more vivid memories for prior media violence than males. Implications for cultivation, the heuristic processing model, and vividness research are discussed.     

Social support and victims of crime: Matching event,support, and outcome

Investigated the buffering properties of six types of social support (three perceived, three received) with regard to four psychological consequences (depression, anxiety, fear of crime, hostility) of criminal victimization (violent crime, property crime). These relationships were examined using longitudinal data collected from a sample composed of representative subsamples of victims and nonvictims. Effects of the perceived support measures (perceived appraisal support, perceived tangible support, self-esteem) were more pervasive than those of the received support measures (received informational support, received tangible support, received emotional support). Perceived support consistently exhibited buffering effects, protecting both violent and property crime victims against various symptoms they would have otherwise experienced. The stress-buffering capabilities of received support were limited to informational and tangible help protecting victims of violence from experiencing excessive fear. These findings are discussed in the context of recent theoretical developments concerning the stress-support matching hypothesis.     

Film violence and young offenders

Recent assertions have been made that viewing violent material on film and video may influence children and adolescents who commit violent acts. It has also been proposed that heavy exposure to television violence in childhood is associated with violent crime as an adult, although others have emphasized that experiencing “real” violence as a child has a much greater effect on aggressive predispositions. Ways in which screen violence can effect behavior includes: imitation of violent roles and acts of aggression, triggering aggressive impulses in predisposed individuals, desensitizing feelings of sympathy towards victims, creating an indifference to the use of violence, and creating a frame of mind that sees violent acts as a socially acceptable response to stress and frustration. It is argued that young offenders may like violent videos because of their aggressive background and behavioral tendencies. Whether such tastes reinforce violent behavior and increase the frequency of aggressive acts and antisocial behavior is open to question. This question needs an urgent answer given the availability of violent video film either to be viewed in the home environment appropriately (i.e., the whole film in real time) or inappropriately (i.e., from one violent scene to the next viewed in slow motion and freeze-frame).     

Street Youth,Gender, Financial Strain,and Crime: Exploring Broidy and Agnew's Extension to General Strain Theory

General strain theory posits that adversive circumstances experienced by youths increase the likelihood of criminal behavior. Broidy and Agnew argue that while the underlying process identified in the general strain model will be applicable to both male and female crime different models of strain may be required to highlight gender differences in the underlying process. Utilizing a “high risk” sample of 400 homeless street youths the study examines how socioeconomic strain in the forms of homelessness, monetary dissatisfaction, and relative deprivation may be differentially linked to property and violent crime depending on gender. The conditioning effects of deviant attitudes, deviant peers, attributions, self-efficacy, and self-esteem are also examined. The results reveal few gender differences in the main effects of the different types of strain on crime. There are, however, gender differences in the way the conditioning variables impact the link between forms of strain and crime.     

Situationally Equivocal Eyewitness Evidence and the Violence of Crimes

Eyewitness evidence is amongst the most important types of evidence in investigative and juridical proceedings. Yet, eyewitness evidence frequently derives from observations made under situationally equivocal conditions, including such factors as darkness and physical obstruction of view. The effect of the violence of a given crime on potential jurors' evaluation of such equivocal evidence was addressed. A witness's identification of a suspect in a violent crime was generated in three versions, varying only in the level of violence of the crime. Respondents were more likely to accept this identification as accurate under more violent conditions and were also less likely to report noticing or considering equivocal aspects (darkness and physical obstruction) in situations of greater violence. Predisposing factors to judgement of guilt lay significantly in the acceptance of punishment as a viable deterrent to crime and of societal guilt for the criminal's behaviour, although political or religious orientations were not shown to influence these results, and none of these factors interacted with the violence of the crime to influence judgement of guilt or innocence. These findings indicate the importance of affective factors in judgements of guilt or innocence, especially when these judgements are based on situationally equivocal eyewitness evidence.
