This study draws upon theory from Marx, Weber, postmaterialism, individualism and system justification to explore cultural attitudes and beliefs surroudning competition. Authors test relationships between the attitudes towards competition and economic and religious variables.

This study investigates theories of male initiation ceremonies. The author examines a hypothesis related to child-rearing variables (sleeping arrangements and post-partum taboo) and rejects it based on empirical analysis. An alternative hypothesis related to male solidarity is offered.

This paper examines two measures of cultural complexity: Carneiro’s (1970) scale and codes assembled at the University of Pittsburg. Analysis suggests the two measures are compatible, thus providing evidence for their validity. The authors assess the usefulness of a cultural complexity scale by testing the relationship between descent rules and cultural complexity. Significant associations suggest that cultural complexity is related to social organization and is thereby a useful measure.

This study seeks to examine the influence that UV radiation and climate might have on gender inequality, and tests two extant theories on why gender inequality exists -- the life-history theory (aligned with climate) and the cognitive performance theory (aligned with UV radiation). The model with UV radiation as the main predictor fits the data on gender inequality the best, and pathogen prevalence and the ACP1*B allele were also found to be associated with gender inequality. The model was found to be robust across continents and ancestry. The study also highlights the need for further research to better understand the complex interplay of these factors in different cultures.
