Race,Sex, and Perception of the Occupational Opportunity Structure among College Students*

Questionnaires were administered to 70 black female, 75 black male, 1,457 white female and 1,429 white male university freshmen. In order to test three alternative theories regarding perceptions of discrimination, analyses of variance related sex, race, and SES to total scores of perceived occupational discrimination against blacks (BDST) and against women (WDST). Blacks perceived significantly more discrimination against black people than did whites; neither sex nor SES differentialed scores on BDST. Black females and white males perceived significantly more discrimination against women than did white females; black females had the highest and white females the lowest WDST scores. A discriminant analysis on white females indicated that high WDST scorers were characterized by an “underdog syndrome” whereas low WDST scorers held internal, individualistic values. The findings indicated the greatest support for the formulation that differential anticipatory socialization into the role of “a person who is discriminated against” characterized white females who perceived more or less discrimination against women.     

Interrelationships between fertility and marital dissolution: Results of a simultaneous logit model

Previous studies have failed to examine (a) the simultaneity of decisions to bear children and to dissolve a marriage and (b) the effects of the childbearing in the period just before dissolution on the likelihood of disruption. We attempted to resolve both problems by developing a simultaneous logit model of the interrelationship between the probability of separation and of having a birth during this period (when dissolution presumably is being considered). The model was estimated at successive durations of first marriage, using data for white women in the 1970 National Fertility Survey. The results indicate that childbearing patterns— number of children and age of youngest child at the beginning of the marital interval being studied and fertility during the interval—did not influence the likelihood of separation in simple or consistent ways over the marital life course, nor did marital strife (as indicated by separation) seem to affect childbearing throughout marriage.     

Estimating the movement among staging areas of the barnacle goose ( Branta leucopsis )

Barnacle geese ( Branta leucopsis ) make annual migrations between breeding colonies in northern Europe and Eurasia to wintering grounds in Holland. During the migration, they sojourn for several weeks in five areas on the northern coast of Germany. Observers traverse these areas during the course of studying the flocks. Previous belief was that there was little exchange of birds among the five areas; however, some banded birds were observed in more than one area indicating that some movement takes place. In this presentation, we estimate the movement rates among the areas using open- and closed-population models.
