Precise chronology of Polynesian temple construction and use for southeastern Maui, Hawaiian Islands determined by 230Th dating of corals
2015
International audience; Emergent archaic states in pre-contact Hawai'i used a ritual control hierarchy implemented through a system of temples to manage production, extract tribute, and reinforce the legitimacy of the ruling elites. Based on a limited sample of precise 230Th dates from coral offerings on Maui Island temples it had been hypothesized that this temple system rapidly expanded during the period from A.D. 1580–1640. We tested this hypothesis by obtaining an expanded sample of 39 new 230Th coral dates from temples in Kahikinui District, and one sample from the summit of a cinder cone that likely had ritual significance. Combined with seven coral dates previously obtained, this yie…

This is an Open Access article under the CC BY 4.0 licenseBackground Underweight, overweight, and obesity in childhood and adolescence are associated with adverse health consequences throughout the life-course. Our aim was to estimate worldwide trends in mean body-mass index (BMI) and a comprehensive set of BMI categories that cover underweight to obesity in children and adolescents, and to compare trends with those of adults. Methods We pooled 2416 population-based studies with measurements of height and weight on 128·9 million participants aged 5 years and older, including 31·5 million aged 5–19 years. We used a Bayesian hierarchical model …
