Laser ablation depth profiling of U-series and Sr isotopes in human fossils

We have explored laser depth profiling to obtain data sets for U-series as well as Sr analyses. Laser probing with an 81 μm spot size allows for the exploration of low uranium domains of up to 400 μm below the outer surface in tooth enamel. These low U domains will contain Sr isotope compositions of the individual, that are least affected by diagenetic Sr overprints. The small holes drilled for U surveying are not visible to the naked eye. Using larger spot sizes of around 233 μm, laser drilling can be used to obtain reliable U-series isotope data to a depth of approximately 1000 μm in enamel and around 1300 μm in bone. Furthermore, meaningful ⁸⁷Sr/⁸⁶Sr isotope data can also be obtained with this spot size. Using our sampling strategy, the overall damage to a human tooth is minute, as demonstrated on a Neanderthal tooth from Moula-Guercy. We expect that laser ablation depth profiling will become routine for gaining insights into the age of human fossils and the migrations of ancient humans.     

Hospitality in pre-viking Anglo-Saxon England

This article studies the question of Anglo-Saxon hospitality, that is, in the first place, the gift (from a host to a guest) of food, fodder, roof and bed for a night or for a longer term. Contrary to Romantic visions, it was nothing like a spontaneous and free practice: Marcel Mauss and other anthropologists after him have shown that giving and receiving were obligations, compulsory acts in pre-market societies. In Anglo-Saxon England, hospitality was always a duty, strictly limited and framed by custom. It may have been provided to a single traveller, to a member of a formal or informal network (particularly ecclesiastical), to a king or to his agents in the form of a pastus or feorm: a kind of 'guesting' or compulsory hospitality which was progressively given up by kings as they booked lands to religious institutions. The forms and beneficiaries may vary, but the opposition between 'spontaneous' feasting and 'compulsory' guesting must not be stressed too much: hospitality was always a kind of binding exchange, even when it assumed the shape, the aspect, and even the values of a free and open practice .     

The Political Order and Corporal Coercion in Kanak Societies of the Past (New Caledonia)

Till the mid-19th century, in Kanak institutions in north central Grande Terre (New Caledonia), chiefs received their titles from the ‘masters of the land’. To add material and symbolic power to their preeminent position, they received human sacrifices, as one of their kinspeople offered his/her body; and they waged warfare outside the chiefdom. Their fame was proportional to control over human bodies. Based on historical sources and ethnographic information gathered in the field, the effort is made to see how these precolonial cannibalistic practices fit into political systems. A comparison is made between Kanak chiefs and Melanesian big men and great men.     

Histoire des idées, sociologie des croyances et processus argumentatifs scepticisme et modernité d’après Richard H. Popkin

This paper claims to show the relevance of the classical book by Richard H. Popkin from the point of view of a sociological and anthropological analysis of the collective processes of doubt and assent. This examination implies, however, that we analyse the fine differences between the history of ideas, the sociology of knowledge, the ethnology of beliefs and epistemology. The examination deserves to be carried out as well for the understanding of the increase of scepticism in the 17th century as for the spread of the wave of contemporary relativism. The latter certainly has to be distinguished, as Popkin suggests, from a form of moderate scepticism close to critical rationalism.
