The Ballast Point report (Five Thousand Years of Maritime Subsistence at CA-SDI-48, on Ballast Point, San Diego County, California) was the first such report to document the complexity of maritime subsistence in San Diego County from circa 6,600 B.P. to 1,300 B.P. It was completed in 1988, and later published by Coyote Press in 1998, "with very minor editing and corrections." CRM reports by their very nature are usually not structured for publication; however, the Coyote Press publishers felt that this report was publishable in the format provided. Coyote Press is one of the few outlets for CRM publications and should be commended for publishing "grey literature," therein ensuring that these studies are available to the archaeological community.

A heterosexual group of nonreproductive rhesus ( Macaca mulatto ) containing vasectomized males was compared with a matched control group containing intact males. Comparisons were made on data collected before the birth of the first infant in the control group. Three Darwinian a priori hypotheses were used to predict differences between groups. The first hypothesis correctly predicted more affiliative and sexual behavior among experimental heterosexual dyads. The results did not support the second hypothesis that predicted less affiliation between experimental males. The third hypothesis correctly predicted that heterosexual affiliation and sexual behavior would occur between more of the possible heterosexual dyads in the experimental group. Two-tailed tests showed the females in the reproductive group engaged in significantly less intrasexual affiliation. The results suggest failure to reproduce has a causal influence on the affiliative and sexual interaction patterns of rhesus macaques.

Affiliation is often used as an intervening variable in behavioral studies of nonhuman primates. Variables used to measure affiliation should be strongly correlated if it is a valid intervening variable. Social context also should not strongly influence relationships between variables used to measure affiliation. Few studies have, however, reported either the correlations between variables used to assess affiliation or the influence of social context on relationships between the variables. Correlations between affiliative variables were therefore calculated on data from two groups of rhesus {Macaca mulatta)and influences of social context on these correlations were assessed. Affiliation was measured with 7 variables. Two methods were used to investigate the influence of social context: Analyses were made of interactions between several age/sex categories of individuals. Comparisons were made between an experimental group and a matched control group. There were higher rates of sexual behavior in the experimental group. The mature males in the experimental group were vasectomized so females did not conceive. In this group females had repeated nonpregnant estrous cycles. Males were intact in the control group. In this group the mature females conceived and were pregnant during data collection. The variables were significantly correlated across all social contexts. Affiliation may therefore be a useful intervening variable. The magnitude of the correlations between variables did vary considerably across social contexts. Sometimes the sign of the correlations between measures changed as a function of social context. Analyses of individual variables and their interrelationships may therefore be necessary for detailed understanding of the meaning of affiliative interactions in nonhuman primates.
