Follow-up after release of insanity acquittees, mentally disordered offenders, and convicted felons

The authors compared 127 insanity acquittees in the state of Maryland with a matched prisoner control group of 127 convicted felons and a comparison group of 135 mentally disordered prisoners transferred for hospital treatment. Subjects were followed from five to 17 years after discharge from hospital or release from prison. Subsequent arrests, hospitalizations, employment, and functioning of these large cohorts were studied and compared. The study focused on outcome data at five years after release. The authors found that, at five years postrelease, 54.3 percent of the insanity acquittees, 65.4 percent of the prisoner control group, and 73.3 percent of the mentally disordered prison transfers were rearrested. At 17 years postrelease, rearrest rates increased to 65.8 percent of the insanity acquittees, 75.4 percent of the prisoner controls, and 78.4 percent of the prison transfers. Significantly more mentally disordered prison transfers than NGRIs were rehospitalized during the follow-up period. Overall, the prison transfers had significantly poorer outcomes on nearly all variables studied compared with the other two groups. The authors conclude that although there were a substantial number of rearrests among insanity acquittees, that group had a statistically significantly lower rate of criminal activity compared with the other two groups of offenders.     

History of spouse violence against mother: Correlated risks and unique effects in child mental health

The present study examined mental health risk associated with lifetime occurrence of spouse violence against mother among 303 10 to 12 year-old inner-city children. Maternal report data showed a 30% prevalence rate for lifetime occurrence of spouse violence in this sample. Results of correlational analyses indicated that violence against mother was associated with several other historical risk factors including divorce, parental drinking problems, and incarceration of father. Multiple regression analyses controlling for the effects of demographic and historical risk factors that correlated with violence against mother revealed that violence accounted for significant unique variance in girls' self-reports of conduct problems, but did not account for unique variance in boys' symptomatology. Implications of these results for understanding the effects of violence against mother on children and for the development of empirically based interventions for children in those families are discussed.     

Cognitive tempo,violent video games,and aggressive behavior in young boys

In a factorial design, impulsive and reflective children played video games with aggressive or nonaggressive themes. Interpersonal aggression and aggression toward inanimate objects were assessed in a free-play setting and interpersonal aggression was assessed during a frustrating situation. Results indicated that subjects who played the video game with aggressive content exhibited significantly more object aggression during free-play and more interpersonal aggression during the frustrating situation than youngsters who played nonaggressive video games. Aggressive behavior was unaffected by cognitive tempo.     

A linear inequality method of establishing certain social choice conjectures

This paper demonstrates the equivalence between sets of linear inequalities and a variety of social choice problems, a fact which permits the solution of the problems using linear programming techniques. An important advantage of this approach is that the primal solution of the linear programming problem, if one exists, provides a specific example illustrating the social choice conjecture under consideration. Examples illustrating this approach to several standard types of social choice problems are presented. Social choice theory relies heavily on demonstrations that various social choice functions can disagree with one another or that these functions are inconsistent with one or more fundamental conditions or axioms held to be desirable properties of a method of deriving a “fair and reasonable” social choice from a set of individual preference orderings. A large class of such conjectures can be shown to be equivalent to systems of linear inequalities. This equivalence makes it possible to establish the truth or falsehood of such social choice conjectures by testing the systems for consistency or by employing one of the many available algorithms to solve the corresponding linear programs. We will give below a number of examples of conjectures resolved in this fashion, but first we must show how the appropriate inequality systems and linear programs may be found.
