These papers, produced for a graduate seminar at the University of Wisconsin, Madison, represent an attempt to devise a methodology for the comparative study of adult education. "Introduction," by G.S. Bains, provides a justification for the study of comparative adult education. "Comparative Philosophies of Adult Education," by Donald Verwayen, and "An Exploration of the 'Developmental/Rationalistic' Dichotomy for Comparative Adult Education Studies," by Michael J. Heus, examine basic philosophies. "The National Establishment of Adult Education," by Barbara D'Onofrio, concerns the status of adult education. "The Organization of Adult Education," by A. Brian Calhoun, "A Comparative Adult Education Inventory," by Marianne Maynard, and "The Arrangement of Study Activities," by Thomas C. Smrcka, present different forms of arrangement. "Cultural Differences and Evaluation," by D. Merrill Ewert, explores cultural influences creating differences between countries. (KM)

Formulae due to Dahlberg for computing the numbers of consanguineous matings to be expected under random mating fail in the case of overlapping generations. The concept of random mating can be extended to cover overlapping generations by making the chance of muting between a male and female depend on the interval between their dates of birth. This concept of random mating is illustrated by a numerical example based on a simple hypothetical organism. The implications of the suggested concept of random mating can be explored for species with complicated demographic characteristics, and man in particular, by means of a mathematical model in continuous time. Calculations of the frequencies of various types of consanguineous marriage to be expected under random mating are presented and compared with statistics of consanguineous marriages occurring in various countries. Discrepancies and similarities between observed and theoretical values are discussed.

A review of the use of oral contraceptives from 1956-1966 is presented for the U.S. and several European and Latin American countries. In 1969 an estimated 9,600,000 to 10,700,000 women in the world were pill users. Estimates for the number in 1985 vary from 20,000,000 to 40,000,000. However estimates are difficult because of the improvements in fertility control that are likely to occur in the future.
