Using Propensity Score Matching to Understand the Relationship between Gang Membership and Violent Victimization: A Research Note

Due to methodological limitations, such as unmatched gang samples and a lack of longitudinal investigations, it remains unresolved whether joining a gang leads to future violent victimization or both share a set of common causes. Guided by selection, facilitation, and enhancement perspectives, the current study applied Propensity Score Matching on data from the Gang Resistance Education and Training longitudinal study to investigate the nature of the gang‐violent victimization relationship. Results indicated antecedent differences between those who did and did not join gangs, particularly violent victimization and delinquency. When gang and non‐gang members with similar propensities for joining were matched, the relationship between gang membership and violent victimization dissipated. Findings suggest policy attention to early delinquency and victimization risk factors generally.     

From the Asian Boyz to the Zhu Lian Bang (the Bamboo Union Gang): A Typological Analysis of Delinquent Asian Gangs

Developing a typology for delinquent and criminal gangs has a long history in criminology and criminal justice. Although many typologies have been proposed in the past eight decades, the great majority of these classifications are based on the consideration of one single factor. This approach obviously oversimplifies the nature of gangs and may give gang researchers an impression that gangs of a certain category differ totally from those of another category. The author of this paper argues that differences between gangs are relative, not absolute. To demonstrate this point, a nomenclature on Asian gangs based on the different combinations of the three factors of political belief, organizational layout, and political connection is suggested. According to this nomenclature, Asian gangs can be conceptually categorized as STP, SEP, STN, SEN, ITP, IEP, ITN, and IEN types.

Violence and Gangs: Gender Differences in Perceptions and Behavior

Most research on violence has focused on males, but recent studies indicatethat females are also involved in violent crimes. Few studies, to date,have examined whether different or similar models explain male and femaleinvolvement in violent behavior. In the current research, we examine therelative contribution of social bond, self-control and social learningconcepts to the explanation of male and female violent offending. We alsoexplore the unique contribution of gang membership, school environment andprior victimization to these explanatory models. Using a multisite sampleof eighth-grade students, we find that results of a Chow test indicate theneed for separate theoretical models. Despite some similarities, differentfactors account for male and female rates of violent behavior.     

Revisiting the Use of Propensity Score Matching to Understand the Relationship between Gang Membership and Violent Victimization: A Cautionary Note

Previous research has consistently reported that gang members are more likely to experience violent victimization compared to non‐gang members. Recently, however, a study challenged this conventional wisdom using the Gang Resistance Education and Training (GREAT) data. Employing propensity score matching (PSM), this study reported no significant differences in violent victimization between gang and non‐gang members. Upon closer examination of the GREAT data and the PSM process used in this study, we note several theoretical, methodological, and statistical concerns. We reanalyze the GREAT data using both negative binomial regression and PSM. We find that self‐reported gang members were significantly more likely to report subsequent violent victimization compared to non‐gang members. Although contrary to this previous study, our findings are consistent with the bulk of previous empirical research and widely held beliefs about the relationship between gang membership and violent victimization.     

Broadcasting Badness: Violence,Identity, and Performance in the Online Gang Rap Scene

This study contributes to an emerging literature both detailing Internet usage among street gangs and gang members and exploring how street life is presented in underground rap music. We present a content and cultural analysis of 78 rap videos posted on YouTube by gang members in Buffalo, New York, between 2009 and the first few months of 2015. Violence was the most dominant and consistent theme in the videos. We find that online space operates like a virtual street corner enabling individuals and groups to perform social and collective gang identities that emphasize and exaggerate their capacities for lethal violence. Online gang rap videos use violent imagery, revisit violent events, and reference gang conflicts to enhance both gang myth-making and social or collective identity development.     

Slash,Shoot, Kill: Gang Recruitment of Children and the Penalties Gangs Face

Criminal street gang recruitment of minors has proliferated through countless communities in the United States as tensions continue to rise between gangs, communities, and the police. In response, many state legislatures have proposed legislation to combat such influence. However, not only are the proposed penalties too lenient, but some states do not even have laws that prosecute criminal street gang recruitment of minors. This note proposes that all 50 states enact an anti–gang recruitment statute specifically targeting recruiters of criminal street gangs by criminalizing gang recruitment of a minor.     

Gangs and Violence: Disentangling the Impact of Gang Membership on the Level and Nature of Offending

Objectives

To determine whether membership in youth gangs provides a unique social forum for violence amplification. This study examines whether gang membership increases the odds of violent offending over and above involvement in general delinquent and criminal behavior.

Methods

Five waves of data from a multi-site (seven cities) panel study of over 3,700 youth originally nested within 31 schools are analyzed. We estimate four level repeated measures item response theory models, which include a parameter to differentiate the difference in the log of the expected event-rate for violent offense items to the log of the expected event-rate for nonviolent offense items.

Results

Depending on the comparison group (gang youth, overall sample), periods of active gang membership were associated with a 10 or 21% increase in the odds of involvement in violent incidents. When the sample is restricted to youth who report gang membership during the study, the proportionate increase in the odds of violence associated with gangs is statistically similar for males and females. After youth reported leaving the gang their propensity for violence was not significantly different than comparison group observations, although levels of general offending remain elevated.

Conclusions

While results are limited by the school-based sampling strategy, the importance of gang prevention and intervention programming for violence reduction is highlighted. Preventing youth from gang membership or shortening the length of gang careers through interventions may reduce absolute levels of violence.     

Victims of sexual assault perpetrated by female youth: an exploratory study of gender differences*

ABSTRACT

This study examines sexual offending behaviour of juvenile females and juvenile males who come to the attention of the police. Using victim age as an analytical tool and more than 20 years of incident-level crime data, perpetrator, victim, and offense characteristics are compared to assess if the offending behaviours of juvenile females and juvenile males differ when the victim is a child versus a peer. The multinomial logistic regression showed there were differences in offending between juvenile females and juvenile males dependent on type of victim. Perpetrator substance abuse, victim sex, victim-offender relationship, type of sexual assault, use of force, location of the sexual assault, the time of day of the sexual assault, and whether or not the incident resulted in an arrest all reliably predicted these differences. The results reinforce the field's call for a greater development of a gendered understanding of sexual offending behaviour.     

Dangerous Places: Gang Members and Neighborhood Levels of Gun Assault

Despite attention to the role of gangs in urban gun violence, much remains to be learned about the spatial distribution and consequences of residential gang membership. This study uses data from St. Louis to examine the effects of resident gang membership on rates of gun assault. We also consider whether gun violence is conditioned by the level of gang membership in surrounding communities. As anticipated, communities with the highest number of gang members also have the highest rates of gun assault. However, much of the impact of gang membership on gun assaults extends outside of the boundaries of gang neighborhoods, especially those neighborhoods with few or no gang members. The number of gang members in surrounding neighborhoods has no discernible effect on gun assaults in communities with higher rates of gang membership. Finally, controlling for the spatial proximity of residential gang membership helps to account for some of the association between neighborhood disadvantage and gun assaults.     

Gangs and Coups D' Streets in the New World Disorder: Protean Insurgents in Post-modern War

The mutation of protean “street gangs” to insurgents illustrates that insurgents need not be ideologically oriented, and need not be traditional revolutionary fighters emerging from the mountains and jungles to take down or control a government. Rather, they may have their own specific commercial money-making motives, and can emerge out of the favelas, callampas, villas miserias, and pueblas jovenes (city slums) not so much to replace governments as to gain very lucrative freedom of movement and action within a supposedly sovereign national-state. Also, mature second and third generation gangs have been known to act as proxies and mercenaries for traditional nation-states that want to maintain “plausible deniability,” and to act as mercenaries for warlords, organized criminal organizations, and/or drug-trafficking cartels that—on certain occasions—need additional “fire-power”. The instability and lack of individual and state security generated by gangs phenomenon and their nefarious allies are also known to lead to the radical change of failed state status. In these terms, gangs are no longer a singular law enforcement issue. As crime and war become more and more indistinguishable, gangs must be considered a larger national security issue—that, paradoxically, must be viewed as a local concept.     

Gang Activity and Overall Levels of Crime: A New Mapping Tool for Defining Areas of Gang Activity Using Police Records

In this note, a new method for defining gang activity areas based uponpolice records is illustrated using the Chicago Police Department's1996 incident files. This method is based upon standard geographictechniques and uses a uniform grid that divides the city into 150-msquares. It is shown that this technique may be useful both in describinggang activity areas and in describing the spatial distribution of crime inlarge cities. A strong relationship is found between the number of gangsthat are active in an area and the general level of criminal activity.

Understanding the Role of Repeat Victims in the Production of Annual US Victimization Rates

Victimization incidence rates produced from the National Crime Victimization Survey (NCVS) are a generally accepted annual indicator of the amount and type of crime in the United States. However, persons who report a large number of similar victimizations—known as series victimizations in the NCVS—are currently excluded in government reports of annual violent victimizations. This paper quantifies the effect of series incident counting procedures on national estimates of violent victimization. The findings suggest that these high-volume repeat victims can have a significant impact on the magnitude and distribution of violent victimization. Current government counting rules that exclude series incidents do not include about three out of every five violent victimizations and distorts the characterization and risk of violence in the United States. However, the inclusion of series incidents introduces significant estimate instability. One remedy is to use prevalence rates in concert with incidence rates to present a more complete and reliable picture of victimization.

The Role of School-Related Bonding Factors and Gender: Correlates of Gang Membership Among Adolescents

In the past several decades both the education and criminology literatures have examined the influence of school factors on the attitudes and behaviors of adolescents. This literature shows that school-related factors, especially those related to social bonding, are relevant to explaining delinquent behavior. This research examines the efficacy of school-related bonding factors in explaining gang membership. In addition, it examines whether these bonding factors differentially explain male and female gang membership. The results show that delinquent involvement is the strongest predictor of gang membership among middle school children. Although several bonding variables are related to gang membership, their influence is very weak. In addition, we do not find support for the hypothesis that these variables differentially explain male and female gang membership. Implications and suggestions for future research are discussed.     

Contributions of quantitative methods to the study of gender and crime,or bootstrapping our way into the theoretical thicket

Researchers concur on the importance of gender to the study of crime but not on the particular methodological strategy that should be used when studying the gender-crime relationship. This paper examines the actual and potential contributions of quantitative methods for unpacking the gender-crime relationship. Three bodies of literature pertaining to the gender-crime relationship are examined: (i) offending, (ii) victimization, and (iii) criminal justice processing. The findings from this review indicate that while much knowledge about the gender-crime relationship has been uncovered with quantitative data, a commensurate amount of theoretical knowledge does not exist. The author concludes with substantive and methodological suggestions for furthering our understanding of the gendercrime relationship. This paper was prepared for the Plenary Session,Journal of Quantitative Criminology 10-year Anniversary, 1995 Annual Meeting of the american Society of Criminology, Boston, MA.     

Self-Control,Violent Offending,and Homicide Victimization: Assessing the General Theory of Crime

Criminologists have long recognized that offending and victimization share common ground. Using Gottfredson and Hirschis general theory of crime, with its emphasis on self-control as a theoretical backdrop, we examine the extent to which self-control is related to both violent offending and homicide victimization. To examine this issue, we use 5-year post-parole data on violent offending and homicide victimization from a sample of parolees from the California Youth Authority. Using rare-events logistic regression models, results indicate that self-control is related to each outcome, but that other risk factors are also uniquely related to each outcome. The implications of this study for theory and future research are addressed.To whom correspondence should be addressed: Department of Criminology, Law and Society, University of Florida, P.O.

Facilitating Violence: A Comparison of Gang-Motivated, Gang-Affiliated, and Nongang Youth Homicides

It is well established that gangs facilitate violent offending by members,but the mechanisms by which that facilitation occurs remain unclear. Gangsmay promote violence indirectly by facilitating members' access to riskysituations such as drug markets or directly through gang functions such asturf defense. We explore alternative modes of facilitation in a comparisonof gang-affiliated homicides (which involve gang members but do not resultfrom gang activity), gang-motivated homicides (which result from gangactivity), and nongang youth homicides in St. Louis. We find importantdifferences as well as similarities in the time trends and eventcharacteristic of the two types of gang homicide; in key respects thegang-affiliated homicides more closely resemble the nongang events. Thegang-motivated events exhibit a somewhat distinctive spatial patterning,as might be expected from their connection to turf conflicts. However, allthree homicide types are highly concentrated in racially isolated,disadvantaged neighborhoods, which remain the fundamental socialfacilitators of both gang and nongang violence.     

Informing Police Response to Intimate Partner Violence: Predictors of Perceived Usefulness of Risk Assessment Screening

Substantial research has demonstrated the value of using risk assessment tools for the prediction and management of violence risk, including for intimate partner violence (IPV) (Mills, Kroner, and Morgan 2011). Such tools have been advocated for use by police officers (Hilton, Grant, and Rice 2010), but little is known about police officers’ perceptions of using these tools to inform their decision-making. Using a sample of 159 Canadian police officers (73% male, M age =?41.8 years, SD?=?8.9), the current study examined police officer’s experiences with IPV risk tools, their attitudes about using such tools, and identified predictors of these attitudes using an online survey. Most of this sample had previously used an IPV risk tool, which was most commonly the Brief Spousal Assault Form for the Evaluation of Risk (64.1%). Most police officers rated use of risk tools as at least somewhat to extremely helpful (73.5%), and 67.4% indicated that they would use a risk tool with sufficient training on it. Regression analyses indicated that police officers’ perceived IPV risk tool usefulness was significantly predicted by older respondent age and greater perceived need for guidance in responding to IPV calls. In conclusion, most police officers view IPV risk screening as valuable for informing their responses to such calls for service and are likely to embrace such decision-aids with sufficient training on their potential impact for enhancing safety.
