Consequences of decriminalization of homosexuality: a study of two Australian states

A comparison between homosexual males in two Australian states, Victoria (prior to decriminalization of homosexuality) and South Australia (eight years after decriminalization), indicated that the consequences of decriminalization did not include an increase in the negative aspects of homosexuality, such as public solicitation or sexually transmitted disease. Findings suggest that as a consequence of decriminalization, the psychological adjustment of homosexual men will increase and sexually transmitted diseases and public solicitation will decrease. These data are tentatively interpreted as indicating that there are few if any negative consequences of decriminalizing homosexuality, and a number of positive consequences.     

Hazard-based nonparametric survivor function estimation

Summary.  A representation is developed that expresses the bivariate survivor function as a function of the hazard function for truncated failure time variables. This leads to a class of nonparametric survivor function estimators that avoid negative mass. The transformation from hazard function to survivor function is weakly continuous and compact differentiable, so that such properties as strong consistency, weak convergence to a Gaussian process and bootstrap applicability for a hazard function estimator are inherited by the corresponding survivor function estimator. The set of point mass assignments for a survivor function estimator is readily obtained by using a simple matrix calculation on the set of hazard rate estimators. Special cases arise from a simple empirical hazard rate estimator, and from an empirical hazard rate estimator following the redistribution of singly censored observations within strips. The latter is shown to equal van der Laan's repaired nonparametric maximum likelihood estimator, for which a Greenwood-like variance estimator is given. Simulation studies are presented to compare the moderate sample performance of various nonparametric survivor function estimators.     

Analysing open birth interval distributions

Summary This paper began with the recognition that open birth interval distributions are analogous to age distributions. It then became clear that closed birth interval distributions are, somewhat more loosely, analogous to mortality schedules, and that the relationship between open and closed birth interval distributions could be explored by imitating the formal demography of mortality and age distribution. Pursuing this programme, we develop the formal demography of open and closed birth interval distributions and show that under certain assumptions open interval distributions may be used to estimate closed interval distributions, just as age distributions may be used to estimate mortality. An illustrative application to Indonesian data is given.     

The partisanship of silence: Symbolic politics of school desegration in Boston

This article analyzes the symbolic aspects of the school desegration controversy using disputes in Boston as a case in point. The symbolic communication between actors in the public forum contains implicit views of the rights and obligations of different participants in the controversy, and the role of various individuals and collectives in the history of the controversy. These views also provide a framework for understanding the position of specific actors, which may constrain their ability to participate effectively in the controversy. This article analyzes these constraints with respect to those actors who attempted to establish a mediator role between pro-integration and anti-busing forces.Prepared under grants from the National Institute of Education (NIE-6-00-3-0187, NIE-6-76-0038), National Institute of Mental Health, (R01-MH-27618) and the Carnegie Corporation.

Childhood physical and sexual abuse in China

In order to determine the prevalence and characteristics of childhood physical and sexual abuse in China, the authors conducted a survey in Shanghai. The Dissociative Disorders Interview Schedule was administered to 423 inpatients and 304 outpatients at Shanghai Mental Health Center, and to a non-clinical sample of 618 workers at a clothing factory. The results were compared to a previous sample of 502 respondents in the general population in Winnipeg, Canada. The identities of the perpetrators of physical and sexual abuse, and the types of sexual abuse reported were similar in the two countries; however, the rates of reported abuse were lower in China. Childhood sexual abuse appears to be far less common in the general population in Canada than in China.
