This study reports on a structural analysis which is suggested to confirm and expand upon Nadel's (1951) hypothesis that friendly equality between grandparents and grandchildren appears only with certain patterns of authority in the family.

This article uses factor analysis to identify the key variables underlying the many cross-cultural associations reported by Textor (1967). Twelve factors are identified.

After noticing that there are no cross-cultural phylogenetic studies of grandparent terminologies, the authors use the record from 134 Pama-Nyungan languages to explore the evolution of this kinship category and to evaluate the effects of social structures in this evolution. The authors suggest that there used to be four different terms for grandparents in the proto-Pama-Nyungan language family, which was supported by the data. The results show no evidence of co-evolution between these grandparent systems with neither community marriage organization nor post-marital residence. There is not a significant correlation between grandparent and cross-cousin terms; however, there is some evidence that grand-child terms are correlated to grandparent systems.

Authors conduct a meta-analysis of 17 studies that tested for an association between grandparental survival and grandchild survival in patrilineal populations. Results show that the survival of the maternal grandparents is significantly related to the survival of the grandchild. The survival of the parternal grandparents is not associated with grandchild survival. The authors compare their results to previous hypotheses that relate grandparental and grandoffspring survival and find that there results are most in line with the Local Resource Competition Hypothesis.

This paper presents a comprehensive list of kinship patterns for grandparents, grandchildren, uncles, aunts, nieces and nephews, siblings, cross-cousins, and siblings-in-law. The author based these typologies on over 1000 kinship terminologies from around the world. The geographical distributions of kinship patterns are also included.

Textor summarizes cross-cultural findings on adolescence gender separation pertaining to cultural, environmental, psychological, and social phenomena.

This book discusses the characteristics of adolescence cross-culturally and examines the differences in the adolescent experience for males and females. Several relationships are tested in order to gain an understanding of cross-cultural patterns in adolescence.

This study investigates the relationship between the strength of historic kin-based interaction networks in a region, and the strength of modern state capacity in that region. The author compares two metrics, across a global sample: firstly, the Kinship Intensity Index (KII), which is calculated by region using five variables from the Ethnographic Atlas (societies are combined by region by weighting each EA society using its population size); and secondly, the State Capacity Index (SCI), which measures the functionality of modern-day nation-states. It is found that around the world, countries whose borders have historically been home to societies with strong kin-based interaction networks tend to have a significantly weaker state capacity.

This dissertation discusses the divided theoretical approach to how reincarnation, animism, spirits, and general religious beliefs occur within societies cross-culturally. Matlock offers evidence to support Tyler, contradicting the generally accepted Durkheimian approach, arguing that the belief about souls and spirits may originate in dreams and other empirical experiences, in turn informing and shaping social organization. Durkheim argued the opposite, claiming that religious beliefs reflect social organization such as the clan and kinship. The author states 33 quantitative hypotheses to be tested using 30 of the first 60 sample societies available in the HRAF Probability Sample.

This study uses "rules of combination" to describe internal order in social groups. The author examines kinship structure, and specifically the relationship of the mother's brother towards the son. Results support the hypothesis.
