This article tests for universal patterns in cultural evolution by Guttman scaling on two different worldwide samples of archaeological traditions and on well-known archaeological sequences. The evidence is generally consistent with universal evolutionary sequences.

This article stresses the use of multivariate analysis to study the emergence of states. The authors first discuss how social inequality, population density, and trade affect state development. Next, they turn to a time series regression to formally examine social stratification, urbanization, technological specialization as predictors of political integration. Finally, economic vulnerability and scalar stress are considered as possible underlying factors in the emergence of states.

This study examines the change in political integration over time. Results show that political integration has increased during the past 12,000 years following a quadratic curve. Authors suggest that, following this quadratic model, a world state is likely to appear by AD 5000.

This article uses pre-defined criteria to sample 22 archaeological climate-related disasters from 9 distinct regions from eHRAF Archaeology. It quantitatively tests four hypotheses regarding change in conflict following climate-related disasters using multiple regression analyses and backwards stepwise regression. Findings demonstrate association between political strategy/authority decision making and degree of post climate disaster conflict.

The present study investigates whether there is resilience variability following climate-related disasters in societies that are corporate-oriented, which promote participatory and inclusive structures, and exclusionary-oriented, which limit political authority and power. The findings offer modest support for social resilience theory that more flexible (i.e. more participatory) societies would be more resilient after a disaster than less flexible societies. Although only 5 of 14 correlations are significant, the direction is significant by a binomial sign test.

This study replicates John L. Fischer's (1961) cross-cultural analysis to demonstrate the correlation between art styles and social hierarchy and postmarital residence. The author suggests that archaeological ceramics might be used to predict social characteristics of prehistoric societies.
