Criminologists are ofren interested in examining interactive effects within a regression context. For example, " holding other relevant factors constant, is the effect of delinquent peers on one's own delinquent conduct the same for males and females? " or " is the effect of a given treatment program comparable between first-time and repeat offend-ers? " A(More)
On the basis of prior research findings that employed youth, and especially intensively employed youth, have higher rates of delinquent behavior and lower academic achievement, scholars have called for limits on the maximum number of hours per week that teenagers are allowed to work. We use the National Longitudinal Survey of Youth 1997 to assess the claim(More)

OBJECTIVE To estimate the cumulative proportion of youth who self-report having been arrested or taken into custody for illegal or delinquent offenses (excluding arrests for minor traffic violations) from ages 8 to 23 years. METHODS Self-reported arrest history data (excluding arrests for minor traffic violations) from the National Longitudinal Survey of(More)
This article examines the well-documented relationship between early initiation or onset of criminal behavior and a heightened risk of involvement in offending. Previous research examining this question conducted by Nagin and Farrington (Criminology 30:235-260, 1992a; Criminology 30:501-523, 1992b) used data from the Cambridge Study in Delinquent(More)
Delaware. His research focuses on evaluation science, youth substance abuse, and the effectiveness of drug and HIV interventions for criminal justice offenders. He is the author/co-author of over 100 articles on substance abuse, treatment effectiveness, and methodology. Daniel J. O'Connell is a Scientist at the Center for Drug and Alcohol Studies,(More)
There has been a longstanding debate over the effectiveness of correctional institutions. Some argue that incarceration deters offenders while others argue that the experience of being incarcerated causes individuals to continue in their life of crime. Resolving this debate is of particular importance for young individuals when there is a national push for(More)
Past research on the relationship between school dropout and offending is inconclusive. In explaining their findings, researchers have focused on strain and control theories, and have been unable to rule out selection effects. A key advance in understanding the effect of high school dropout is disaggregation by reason for dropout. Waves one through five of(More)
Though scholars recognize that peer-based risks for offending are especially robust, a handful of researchers have started to question whether the vulnerability to these risks varies across people in theoretically meaningful ways. For instance, drawing on theory and empirical research, there is reason to suspect that individuals of high and low morality are(More)
A system for the simultaneous display of several functions of one or two variables has been developed. One-variable functions are represented by their graphs, while two-variable functions are displayed by means of contour maps, with a light intensity proportional to the displayed value. By assigning a fixed colour to each contour map, it is possible to(More)
