This article describes categories of deference toward elderly men and women. The authors test for significant differences in the types of deference elderly men and women enjoy, finding that men experience more victual and linguistic deference. Elderly women enjoy more service deference than men, but the difference is not significant.

Using Bayesian models incorporating 40,000 radiocarbon dates from 16 discrete human societies throughout history, this study attempts to identify patterns in human disaster-resilience, at the society level. On average, the study finds that societies that have experienced more catastrophes in the past tend to be more resilient in the face of new disasters, experiencing less severe impacts and quicker recoveries. The authors speculate that this may be due to social memory, as resiliency strategies tend to get passed down across generations. Meanwhile, the models also found that societies more reliant on farming and herding also tend to be more susceptible to crisis, but recover more quickly. Across the 16-society sample, which spanned all of human history, climate-related catastrophes stood out as the most common.

This article explores narcissism and child-rearing. The author presents a theory that, if a society’s structural pattern weakens the marital bond, the mother will be ambivalent toward the son who consequently will become narcissistic. This process would reinforce itself as it is repeated by each generation.

This article investigates commonly accepted theories that purport to explain political centralization and investigate their relevance to sub-Saharan Africa. The leading ideas for the formation of political centralization using a worldwide sample include population density, inter-state warfare, and trade. However, the authors reported these factors are not predictive of the sub-Saharan Africa sample. The authors suggest that the lack of agricultural productivity in sub-Saharan Africa may have stunted population density therefore inhibiting political centralization and that Africa’s poor economic performance is, in part, due to lack of political centralization.

This study examines the treatment of the aged in different societies. Support was found for the hypothesis that the amount information controlled by the aged is positively associated with the degree of esteem in which they are held by other members of the society.

This chapter examines correlates of gerontrocide. Previously suggested predictors, such as nomadism and harsh climate, were not found to be associated with gerontrocide, but data suggested that several other variables such as social stratification, subsistence type, and rule of descent, are significant predictors.

This study explores predictors of variation in two dimensions of marital residence patterns among hunter-gatherers: 1) the tendency toward patrilocality versus matrilocality and 2) the tendency toward unilocality versus bilocality.

The present research investigates food sharing and labor sharing practices of 98 nonindustrial societies. The aims are to: 1) document the frequency and scope of sharing, and 2) test the theory that greater sharing is adaptive in societies subject to more resource stress (including natural hazards).

This article uses the Standard Cross-Cultural Samples to test the relationship between disease and economic growth among sub-Saharan African societies. The authors suggest that a higher disease prevalence limits social integration and economic development since pre-colonial times. The variable measuring economic growth is the complexity of large or impressive structures. The hypotheses are that 1) pathogen stress is negatively correlated to the presence of complex buildings, and 2) pathogen stress is positively correlated to increased ethnic diversity. The results support both hypotheses, and there are additional results, like 1) the negative correlation between pathogen stress and current income per capita and 2) the negative correlation between the increased ethnic diversity and current income per capita. Overall, this article shows the robust relationship between disease and economic development.

This study relates the type of games present in a society to the level of cultural complexity. Authors use a "game-type combination scale" that categorizes societies as having: 1) games of physical skill only; 2) games of physical skill and games of chance; and 3) games of physical skill, games of chance, and games of strategy. Results show a relationship between the game-type combination scale and indicators of cultural complexity.
