A MODEL OF ETHNIC CONFLICT

We present a model of conflict in which discriminatory government policy or social intolerance is responsive to various forms of ethnic activism, including violence. It is this perceived responsiveness—captured by the probability that the government gives in and accepts a proposed change in ethnic policy—that induces individuals to mobilize, often violently, to support their cause. Yet, mobilization is costly and militants have to be compensated accordingly. The model allows for both financial and human contributions to conflict and allows for a variety of individual attitudes (“radicalism”) towards the cause. The main results concern the effects of within‐group heterogeneity in radicalism and income, as well as the correlation between radicalism and income, in precipitating conflict.     

A treatment program for children with sexual behavior problems

This paper discusses the problems and treatment of children with sexual behavior problems. These children coerce, intimidate or force other children by threats of physical harm to comply with their sexual requests, frequently a reenactment of their own experiences. This paper describes a comprehensive therapeutic foster care approach to these children.     

Sibling incest in the royal families of Egypt,Peru, and Hawaii

Analysts of the incest taboo who believe that cultural determinants alone are a sufficient explanation of human incest avoidance frequently cite alleged sibling marriages in the royal families of Egypt, Hawaii, and Peru as supporting evidence. If full‐sibling incest were common in intact families in several populous societies (where mates other than siblings were available) incest avoidance theories involving genetic components, and natural selection theory itself, would be seriously challenged because there would then exist successful societies which employ a relatively inefficient reproductive strategy. This review of historical sources regarding the actual practices of royal families reveals that full‐sibling marriages were extremely rare, except during the Ptolemaic reign. Futhermore, succession to the throne was almost never by an offspring of siblings. Brother‐sister marriage was frequent among commoners in Roman Egypt during the first two or three centuries after Christ. Because it is the only example, and because little is known about the marriages, this clear, but solitary, exception is an insufficient basis for rejecting the interactionist thesis.     

Access to homeownership among immigrant groups in Canada

Ces dernières années l'intéret s'est accru pour les expériences des immigrants après leur arrivée dans la societé nord-américaine. Dans cet article, nous argumentons le fait que le logement, et plus spécifiquement le bail, est un sujet important bien que largement négligé en ce qui concerne la vie de l'immigrant dans la société canadienne. En utilisant des chiffres du recensement de 1986 et la structure des modèles log-linéaires, nous examinons les baux des logements des immigrants dans les différentes régions du Canada. On argumente que les immigrants sont différenciés par la culture, le temps et l'espace en ce qui concerne le bail, avec des immigrants plus récents, particuliérement ceux qui arrivent des pays en voie de développement, qui ont des taux de propriété particulierement plus bas.
In recent years interest has grown in the post-arrival experiences of immigrants in North American society. In this paper we argue that housing, and more specifically tenure, is an important, though largely neglected, issue with respect to immigrant life in Canadian society. Using data from the 1986 census and a log-linear modelling framework, we examine housing tenure among immigrants in the regions of Canada. It is argued that immigrants are a culturally, temporally and spatially differentiated sub-population in regard to tenure, with more recent immigrants, especially those from the Developing World, having substantially lower rates of homeownership.     

ON QUANTILES OF SUMS

In this paper we investigate the relationship between the quantiles of a sum of independent continuous random variables and those of its components. Results concerning this relationship are given for the special cases of symmetric distributions, gamma distributions, and for the difference of identically distributed random variables.
