Extending the Study of Continuity and Change: Gender Differences in the Linkage Between Adolescent and Adult Offending

Recently, Paternoster etal. used data from the Cambridge Study in Delinquent Development, a longitudinal study of 411 South London boys mostly born in 1953, to investigate the linkage between adolescent and adult offending and found that variations in adult offending were consistent with a random process after conditioning on adolescent offending. In this paper, we test the robustness of this early study across data sources and genders. Here, we use data from the Dunedin New Zealand 1972 birth cohort study to replicate previous findings regarding stability and change in criminal offending between the adolescent and adult years. In particular, our interest centers on the stochastic properties of the adolescent and adult conviction distribution in the cohort and whether the structure of this distribution is similar for males and females. This replication and extension of prior work is especially important since criminologists have little understanding of the pattern of female adolescent offending or how the patterns are linked to adult offending for women. The analysis reveals that variation in adult offending after conditioning on adolescent offending is consistent with a random (Poisson) process. Furthermore, this pattern is evident for both the males and the females in the Dunedin New Zealand 1972 birth cohort.     

HMO enrollment of Medicare recipients: an analysis of incentives and barriers

Although there has been increased interest in use of the health maintenance organization (HMO) model to resolve a variety of problems relating to provision of health care to older individuals, less than 2 percent of Medicare beneficiaries are currently enrolled in HMOs. This paper examines both legislative and operational barriers to HMO enrollment of the elderly. Legislative reforms, HMO organizational structures, and marketing strategies thought to encourage enrollment of the elderly are discussed.     

Does contact with the justice system deter or promote future delinquency? Results from a longitudinal study of British adolescent twins

What impact does formal punishment have on antisocial conduct—does it deter or promote it? The findings from a long line of research on the labeling tradition indicate formal punishments have the opposite-of-intended consequence of promoting future misbehavior. In another body of work, the results show support for deterrence-based hypotheses that punishment deters future misbehavior. So, which is it? We draw on a nationally representative sample of British adolescent twins from the Environmental Risk (E-Risk) Longitudinal Twin Study to perform a robust test of the deterrence versus labeling question. We leverage a powerful research design in which twins can serve as the counterfactual for their co-twin, thereby ruling out many sources of confounding that have likely impacted prior studies. The pattern of findings provides support for labeling theory, showing that contact with the justice system—through spending a night in jail/prison, being issued an anti-social behaviour order (ASBO), or having an official record—promotes delinquency. We conclude by discussing the impact these findings may have on criminologists’ and practitioners’ perspective on the role of the juvenile justice system in society.
