A computational electoral competition model with social clustering and endogenous interest groups as information brokers

We extend the basic model of spatial competition in two directions. First, political parties and voters do not have complete information but behave adaptively. Political parties use polls to search for policy platforms that maximize the probability of winning an election and the voting decision of voters is influenced by social interaction. Second, we allow for the emergence of interest groups. These interest groups transmit information about voter preferences to the political parties, and they coordinate voting behavior. We use simulation methods to investigate the convergence properties of this model. We find that the introduction of social dynamics and interest groups increases the separation between parties platforms, prohibits convergence to the center of the distribution of voter preferences, and increases the size of the winning set.     

Perspectives on Managing Intractable Conflict

The author, a Swedish diplomat with extensive experience in peace-keeping initiatives of the United Nations, focuses on two questions that are prominent in the management of intractable international conflict: (1) the interplay between short-term and long-term interventions; and (2) the growing "tools" that are available to mediators and other peacemakers, and how to judge their effectiveness. This brief essay is an adaptation of the author's informal remarks at the March, 2002 Hewlett Centers meeting in New York City.     

The Contribution of Organized Youth Sport to Antisocial and Prosocial Behavior in Adolescent Athletes

In this study, we investigated the contribution of organized youth sport to antisocial and prosocial behavior in adolescent athletes. The sample consisted of N=260 male and female soccer players and competitive swimmers, 12 to 18 years of age. Multilevel regression analysis revealed that 8% of the variance in antisocial behavior and 7% of the variance in prosocial behavior could be attributed to characteristics of the sporting environment. Results suggested that coaches who maintain good relationships with their athletes reduce antisocial behavior, and that exposure to relatively high levels of sociomoral reasoning within the immediate context of sporting activities promotes prosocial behavior. These results point to specific aspects of adolescents’ participation in sport that can be used to realize the educational potential of organized youth sport.

Hanging deaths with bound hands: what is the manner?

In Franklin County, Ohio, 3 cases of hangings with bound hands were reported in a 4-month period in 2005. All of the victims were men. In 2 of the 3 cases, the hands were bound behind the back. One victim bound his hands in front of his body. In each case, the police ruled the deaths "suspicious" due to the fact that the victims' hands were bound. Complete investigation is required. Only after a thorough scene investigation, medicolegal autopsy, and knowledge of recent circumstances of the decedent's life can a determination of manner be made.     

Compulsory treatment with clozapine: a retrospective long-term cohort study

BACKGROUND: Clozapine is the gold standard in treatment of treatment-resistant psychotic patients. We know little about the effects of compulsory treatment in patients unwilling to accept the necessary treatment. AIMS: To assess the effectiveness, tolerability and safety of compulsory treatment with clozapine (CTC). METHOD: A cohort of 17 consecutive patients given compulsory treatment with clozapine were rated retrospectively by their treating psychiatrists on the basis of their case notes. RESULTS: CGI-S decreased significantly over time until last observation after a mean of more than 15 months. No patient deteriorated as measured by CGI-I. At last observation as many as ten of the 11 patients still on clozapine were classified as much to very much improved. The degree of custodial restriction at last observation showed improvement in 11 patients and no change in six. No serious adverse events were observed. CONCLUSION: A trial of compulsory treatment with clozapine showed this treatment to be feasible, effective, safe and well tolerated.
