DEMONSTRATING THE VALIDITY OF TWIN RESEARCH IN CRIMINOLOGY

In a recent article published in Criminology, Burt and Simons ( 2014 ) claimed that the statistical violations of the classical twin design render heritability studies useless. Claiming quantitative genetics is “fatally flawed” and describing the results generated from these models as “preposterous,” Burt and Simons took the unprecedented step to call for abandoning heritability studies and their constituent findings. We show that their call for an “end to heritability studies” was premature, misleading, and entirely without merit. Specifically, we trace the history of behavioral genetics and show that 1) the Burt and Simons critique dates back 40 years and has been subject to a broad array of empirical investigations, 2) the violation of assumptions in twin models does not invalidate their results, and 3) Burt and Simons created a distorted and highly misleading portrait of behavioral genetics and those who use quantitative genetic approaches.     

PARENTAL INVOLVEMENT IN THE CRIMINAL JUSTICE SYSTEM AND THE DEVELOPMENT OF YOUTH THEFT,MARIJUANA USE,DEPRESSION, AND POOR ACADEMIC PERFORMANCE*

Explanations for the fact that crime tends to run in families have focused on the deprived social backgrounds of criminal parents, methods of child‐rearing, modeling processes, and genetic mechanisms. However, parental involvement in the criminal justice system itself also might contribute to the intergenerational transmission of crime and have other adverse effects on children's well‐being. We investigated the development of youth problem behavior in relation to parental arrest, conviction, and incarceration in the youngest and oldest samples of the Pittsburgh Youth Study, a longitudinal survey of 1,009 inner‐city boys. Parental arrest and conviction without incarceration did not predict the development of youth problem behavior. Parental incarceration was not associated with increases in marijuana use, depression, or poor academic performance. However, boys experiencing parental incarceration showed greater increases in theft compared with a control group matched on propensity scores. The association between parental incarceration and youth theft was stronger for White youth than for Black youth. Parenting and peer relations after parental incarceration explained about half of its effects on youth theft. Because the effects of parental incarceration were specific to youth theft, labeling and stigma processes might be particularly important for understanding the consequences of parental incarceration for children.     

TRENDS IN VIOLENT CRIME AMONG EX-MENTAL PATIENTS

A central component of the public's conception of the mentally ill is that they are dangerous. This belief receives support from recent studies of the arrest rates of ex-mental patients which suggest that arrests for violent crimes have increased. In order to investigate this issue, samples were taken at two points in time. Analysis of arrest rates revealed that very few ex-mental patients were subsequently arrested for violent crimes, although these rates were higher and increasing faster than these of the general population. Mast significant were the findings that subsequent arrests were best explained by the number of prior arrests and that the percentage of patients with a history of criminal behavior has increased dramatically over time. The implications of these trends in violent crime among ex-mental patients for the perceived link between mental illness and violence and for the social control functions of society are discussed.     

PARENTAL ATTACHMENTS AND DELINQUENCY*

Using the 1972 National Survey of Youth, we analyze attachment to mother and father along several dimensions (i.e., intimacy of communication, affectional identification, supervision, and family activities). We test two hypotheses: (1) as long as a child is strongly attached to one parent, strong ties to the other parent play an insignificant role in reducing delinquency further and (2) single-parent homes are not associated with delinquency as long as the child is strongly attached to the custodial parent. Generally, we find that children who are strongly attached to both parents have a lower probability of self-reported delinquency than children who are strongly attached to only one parent. Further, children living in single-parent homes who are strongly attached to the custodial parent generally have a greater probability of committing delinquent acts than children living in intact homes who are strongly attached to both parents.     

Firm Risk Management in the Face of Product Liability Rules*

This paper addresses the issue of corporate risk management strategies in dealing with products liability law. It views risk management as the dependent variable. How do attributes of the firm and of the law of products liability influence the risk management practices of the corporation? Drawing on the work of Oliver Williamson and others, the paper views the firm as a boundedly rational organization that must devote significant resources in monitoring and controlling its agents. This is especially costly in an environment where the measure of adequate performance (i.e. the design, manufacturing and marketing of a non-defective product) is uncertain and where the criteria used by legal actors (judges and juries) to judge product defectiveness, may vary substantially from the criteria used by the firm's engineers and scientists. Both the costs of control and the level of legal uncertainty are variables. Together they combine to shape a firm's risk management strategy.     

The Georgia Lottery: Assessing Its Administrative, Economic, and Political Effects

This article examines the Georgia lottery as a “policy laboratory” and its potential effect on state‐level policy diffusion. The authors summarize an extensive research project they directed that included a survey of every state that offers a lottery, a general population survey of Georgia citizen attitudes toward the lottery, and results from an economic model summarizing the economic effects of the lottery. The analysis reveals that the Georgia lottery has been a significant source of revenue for the state's budget and operates in an administratively cost‐effective manner. The analysis also confirms the conventional wisdom that lower‐income households spend a greater proportionate share of their income on the lottery and that African Americans are more frequent players than whites. Furthermore, the Georgia lottery enjoys broad public support, the key to which appears to be the earmarking of lottery funds to specific, new, popular education programs. However, the data reveal that those educational programs promulgated by the Georgia lottery benefit citizens from both high and low socioeconomic status. Finally, the article suggests that lottery‐generated funds may reach a plateau or peak during the first decade of implementation and that state policymakers should design lottery‐funded programs accordingly.
