Meeting the Needs of the Adoption Triangle Through Open Adoption: The Birthmother

Open adoption is a relatively new and controversial practice. However, in many cultures this practice is traditional. In this first of a series of articles, the affect of open adoption upon birthparents is discussed. The open process facilitates appropriate grieving, enables decision making and furthers the growth of the birthmother.     

The American Sociological Association dues structure

In this article, we report on the extent of voluntary compliance by ASA members with the Association dues structure. Comparing our findings from a random survey of ASA members with the distribution of member payments by incomebased dues category, we find a fairly high degree of noncompliance in the highest dues category. This implies, and we observe, that higher fractions of ASA members pay dues in the lower income categories than is consistent with their self-reported income. David N.

Adjusting and Comparing Survival Curves by Means of an Additive Risk Model

Survival curves may be adjusted for covariates using Aalen's additive risk model. Survival curves may be compared by taking the ratio of two adjusted survival curves; the ratio is denoted the generalized relative survival rate. Adjusting both survival curves for all but one of a common set of covariates gives the partial relative survival rate, which measures the covariate-specific contribution to the generalized relative survival rate. The generalized and partial relative survival rates have interpretations similar to the traditional relative survival rates frequently used in cancer epidemiology. In fact, the traditional relative survival rate can be generalized to a regression context using the additive risk model. This population-adjusted relative survival rate is an alternative and useful method for removing confounding effects of age, cohorts, and sex. The authors use a data set of malignant melanoma patients diagnosed from 1965 to 1974 in Norway. The 25-year survival of 1967 individuals is studied.
