We discussed several possible causal pathways, including the development of literacy and urban life, and put forward the idea, inspired by life history theory, that absolute affluence would have impacted human motivation and reward systems, nudging people away from short-term strategies (resource acquisition and coercive interactions) and promoting long-term strategies (self-control techniques and cooperative interactions).

Infective illness involving the respiratory tract and gastrointestinal tract together with dermatological illness was common in elite rugby players participating in this international tournament. A delay in reporting of symptoms >24 h could have important clinical implications in player medical care.

Abstract:Background: Professional rugby union is a contact sport with a high risk of injury.

Since the mid-1980s, debates between competing schools of archaeological interpretation have become more theoretical and abstruse, moving away from confrontations over specific methods of analyzing our data. This article reopens arguments over one of the more controversial propositions of the New Archaeology - Saxe's claim that the emergence of formal cemeteries corresponds to the appearance of agnatic lineages monopolizing vital resources through inheritance. The hypothesis is examined in three ways: through a generalized ethnological model; through specific ethnographic data from Taiwan and Kenya; and through a historical comparison of Athens from 500 to 100 BC and Rome from 200 BC to AD 200. It is argued that all three methods lead to a similar conclusion, that many societies do indeed talk about the dead in the way the Saxe/Goldstein hypothesis maintains, but that in any specific instance the cemetery/property message may well be subverted by other arguments which the buriers are making.
