The Causal Impact of Exposure to Deviant Peers: An Experimental Investigation
Ray Paternoster, Jean Marie McGloin, Holly Nguyen, and Kyle J. Thomas
Objectives: This study addresses the enduring question about whether exposure to deviant peers causes individuals to engage in deviance. Ample literature comments on this point, but methodological limitations prevent strong conclusions about causality. Method: The authors conducted a laboratory-based experiment under the guise of a memory/recall study for which participants could earn up to $20. All 91 participants had the opportunity to cheat on a computer-based word recall task by clicking on up to four links that provided access to the words in order to illegitimately earn more money for their performance. In the treatment condition (n = 47), subjects were exposed to a confederate who indicated an intention to cheat, justified this behavior, and cheated on the task. Results: Whereas none of the participants in the control condition cheated on this task, 38 percent of the participants in the treatment condition did. This effect endures when controlling for various attributes of participants in regression models. Supplemental analyses underscore the notion that clicking on the links reflected cheating rather than curiosity. Conclusions: This experiment provides evidence that exposure to a deviant peer can cause individuals to engage in deviance. Future experimental work should focus on determining the precise mechanism/mechanisms responsible.
Spatial, Temporal and Spatio-Temporal Patterns of Maritime Piracy
Elio Marchione and Shane D. Johnson
Objectives: To examine patterns in the timing and location of incidents of maritime piracy to see whether, like many urban crimes, attacks cluster in space and time. Methods: Data for all incidents of maritime piracy worldwide recorded by the National Geospatial Intelligence Agency are analyzed using time-series models and methods originally developed to detect disease contagion. Results: At the macro level, analyses suggest that incidents of pirate attacks are concentrated in five subregions of the earth’s oceans and that the time series for these different subregions differ. At the micro level, analyses suggest that for the last 16 years (or more), pirate attacks appear to cluster in space and time suggesting that patterns are not static but are also not random. Conclusions: Much like other types of crime, pirate attacks cluster in space, and following an attack at one location the risk of others at the same location or nearby is temporarily elevated. The identification of such regularities has implications for the understanding of maritime piracy and for predicting the future locations of attacks.
Estimating a Dose–Response Relationship Between Time Served in Prison and Recidivism
Benjamin Meade, Benjamin Steiner, Matthew Makarios, and Lawrence Travis
Objectives: Estimate the dose–response relationship between time served in prison and offenders’ odds of recidivism. Methods: Using a large, representative sample of adult offenders released from prison under postrelease supervision in the state of Ohio, we examine the relationship between the length of time these offenders served in prison and their odds of recidivism during the year following their release. Multivariate logistic regression and analyses involving propensity score matching for ordered doses are both used to estimate the time served–recidivism relationship. Results: Analyses of these data revealed that offenders confined for longer periods of time had lower odds of recidivism, but these odds were only substantively lower for those offenders who served the longest periods of time in prison. Findings suggest the inverse effect of time served was not realized until after offenders have been confined for at least five years. Conclusion: Study findings indicate that the specific deterrent effect of prison sentences may be limited, and sentences less than five years may be reduced in order to save costs without a substantial threat to public safety.
Child Abuse and Neglect, Developmental Role Attainment, and Adult Arrests
Maureen A. Allwood and Cathy Spatz Widom
This study examines whether developmental role attainment in three areas (high school graduation, employment, and marriage) mediates the relationship between childhood abuse and neglect and adult arrest. Children with documented cases of physical and sexual abuse and neglect (before age 11) and a comparison group of nonabused or neglected children were matched on age, sex, race, and approximate socioeconomic status (N = 1,169) and followed-up and interviewed at approximate age 29. Arrest records were collected from law enforcement agencies. Childhood abuse and neglect predicted decreased likelihood of graduating from high school, current employment, and current marriage and greater likelihood of juvenile and adult arrest. Each of these developmental roles partially mediated the relationship between childhood abuse and neglect and adult arrest. The importance of these three developmental milestones and implications of the results for intervening with abused and neglected youth are discussed.
A Life-course Perspective on Adolescents Attitudes to Police: DARE, Delinquency, and Residential Segregation
Amie M. Schuck
Objectives: Describe the developmental trajectory of perceptions of the police by youth as they transition from adolescence to young adulthood. Method: A longitudinal experiment to evaluate the impact of the D.A.R.E. program (N = 1,773). Latent variable growth modeling was used. Results: A dramatic decline in the favorable attitudes of youth toward the police begins in about seventh grade. More negative perceptions of police are associated with minority racial status, negative experiences with officers, involvement in the delinquent subculture, and greater expressions of skewed legal norms. There is a long-term positive effect of D.A.R.E. on attitudes toward the police, particularly for African American youth. Conclusion: The study highlights the importance of theorizing about perceptions of the police from a life course perspective. Findings raise new policy questions about the long-term impact of school-based programs, such as D.A.R.E., and the role of multiple reference groups in the formation of minorities’ attitudes. More research is needed to gain a better understanding of the cognitive and experiential processes involved in attitude formation.
Changes in Criminal Offending around the Time of Marriage
Torkild Hovde Lyngstad and Torbjørn Skardhamar
Objectives: The authors investigate whether the argument from life-course criminology that marriage leads to reduction in crime or whether the mechanisms leading to lower crime rates might take effect in a period of courtship before the transition to marriage. Method: Using data from population-wide, longitudinal Norwegian administrative registers, the authors estimate within-individual offending propensities before and after marriage for all men marrying in Norway 1997–2001. This approach allows for studying how offending develops over a decade around the time of marriage, for those men who actually marry. Results: The propensity to offend declines sharply prior to marriage. After marriage, there is a small increase in offending. This holds both for all offenses and when the analysis is restricted to felony offenses. Conclusions: The analysis provides no evidence for an effect of marriage on offending. Rather, the results suggest that the lower offending rates of marrieds develop over the years prior to marriage rather than as a consequence of the marriage.
A Stab in the Dark?: A Research Note on Temporal Patterns of Street Robbery
Lisa Tompson and Kate Bowers
Objectives: Test the influence of darkness in the street robbery crime event alongside temperature. Methods: Negative binomial regression models tested darkness and temperature as predictors of street robbery. Units of analysis were four 6-hr time intervals in two U.K. study areas that have different levels of darkness and variations of temperature throughout the year. Results: Darkness is a key factor related to robbery events in both study areas. Traversing from full daylight to full darkness increased the predicted volume of robbery by a multiple of 2.6 in London and 1.2 in Glasgow. Temperature was significant only in the London study area. Interaction terms did not enhance the predictive power of the models. Conclusion: Darkness is an important driving factor in seasonal variation of street robbery. A further implication of the research is that time of the day patterns are crucial to understanding seasonal trends in crime data.
