This article used sub-national, historical and cross-country data to examine if exposure to ultraviolet radiation (UV-R) could be a factor in the formation of individualism and collectivism. The study found support, across all data sets, that increased exposure to UV-R is associated to more collectivism within a culture. The authors theorized that UV-R exposure increases the likelihood of eye disease causing higher rates of blindness. With increased levels of blindness, the more emphasis there will be on close family relations and/or increased uncertainty avoidance from out-groups leading to more collectivism in a culture.

This paper suggests that ancestral irrigation is linked to lower levels of contemporary female labor force participation. The hypothesis is tested using cross-country data, as well as data from various surveys. The study finds evidence that the gender-based division of labor in pre-modern agriculture may be the mechanism behind this relationship, and that cultural transmission across generations, particularly through males, may play a role in perpetuating this pattern.

This study presents a theory for Aberle's (1967) finding that "the merging of relations in the first ascending and descending generations implies the merging of relations in the second ascending and descending generations." The author tests further implications in a cross-cultural sample.

This study examines aggression in folktales in relation to child socialization variables. The author suggests that punishment for aggression and aggression anxiety are related to how aggression is portrayed in folktales. Hypotheses are supported.

This article examines the "sexual conflict" hypothesis which predicts that male genital mutilation should be associated with polygyny and a reduction in the frequency of extramarital sex. Male genital mutilation (MGM) rituals should be highly public and facilitate access to social benefits. Support for these assumptions is provided.

This article examines the relationship between childhood experience and adult personality. This aspect of the adult personality is defined as ego strength. The emphasis of this study is mental health, maturity and the effectiveness of adult learning. Psychoanalytic theory predicts curvilinear relationships but most relationships are linear.

The relationships of aggression and crime to variables of childhood experience, adult behavior, and social structure are cross-culturally analyzed.

This article proposes that societal factors that cause anxiety concerning isolation and self-reliance leads to a preoccupation with dreams. Authors test associations between subsistence economy and marital residence and the use of dreams to seek and control supernatural powers.

This article examines the relationship between sonority and climate. Results suggest that languages spoken in warmer climates have higher levels of sonority than languages spoken in colder climates.

This study explores how differences in group autonomy are related to differences in internal group control. Results support the hypothesis and suggest that group autonomy is positively related to the manipulatory potential of the group and the control that the group has over its members.
