再现火塘边的故事

在茂密纷乱的植被下面．某采砂场的土面被一道黑色的水平带所打断,那是一条窄窄的灰烬层。这个采砂场布满了不规则的台阶和断崖．它的出现打断了摩拉维亚南部葡萄庄园微微起伏的地形。冰川风经由中欧河谷平原携带来细细的沉积物。几千年来形成了数十米厚的地层堆积。这些堆积中埋藏着人类的偶然行为遗留的踪迹：几块燧石、捕获动物的骨骼。或是那来自火塘边的薄薄的灰烬层。它们为人类学家克洛德·列维·斯特劳斯提出的人类区别于世界上其他生物的一种活动——“炊煮”提供了很早的证据．     

Biopower, genetics and livestock breeding: (re)constituting animal populations and heterogeneous biosocial collectivities

Genetic techniques have become increasingly prevalent in livestock breeding, associated with new types of knowledge-practice and changes in the institutional and geographical relationships related to animal husbandry. This paper examines the value of Foucault's concept of 'biopower' to theorising livestock breeding and the implications of the rise of genetic knowledge-practices in agriculture, developing the concept to apply to nonhuman animals and to situations where humans and nonhuman animals are co-constituted through particular knowledge-practices and corporeal meetings. It focuses on the idea of 'population' as a central component of biopower, and relates this to conceptualisations of biosocial collectivity. Reacting to the inherent humanism of Foucault's outlining of biopower, the paper argues for its relevance in relation to nonhuman populations, and for heterogeneous conceptualisations of biosocial collectivity. Drawing on research with UK beef cattle and sheep breed societies, the paper explores how, in practice, populations are constructed in relation to the production of particular sorts of truths concerning, and particular modes of intervention in, the lives of nonhuman animals. It explores how heterogeneous biosocial collectivities are constituted around these interventions. The emergence of genetic techniques is shown to transform the processes constituting populations and heterogeneous biosocial collectivities, and this is discussed in terms of a new inflection of agricultural biopower associated with novel interventions in the lives of livestock animals.     

Subsistence practices and pottery use in Neolithic Jordan: molecular and isotopic evidence

This paper presents direct evidence of subsistence practices and pottery use at a Late Neolithic site at al-Basatîn, northern Jordan. Measurable concentrations of C_16:0 and C_18:0 were recovered from 8 of 10 archaeological pottery fragments through use of a microwave-assisted silica gel and aminopropyl solvent protocol developed for the isolation and concentration of free fatty acids in marine sediments. Subsequent isotopic analysis of the surviving C_16:0 and C_18:0 saturated fatty acids revealed ∂¹³C ratios consistent with those of adipose fats of ruminant and non-ruminant animals pastured on lands adjacent to the Jordan Valley. The high recovery of diagnostic compounds from the al-Basatîn material is discussed in context of a wider examination of the initial development and use of pottery in the Fertile Crescent, and the emerging debate concerning the efficacy of stable carbon isotope values in characterizing organic residues embedded in pottery fragments recovered from the earliest ceramic horizons in the Middle East and Europe.     

The use of a high-resolution 3D Chirp sub-bottom profiler for the reconstruction of the shallow water archaeological site of the Grace Dieu (1439), River Hamble,UK

The remains of Henry V's flagship, the Grace Dieu, currently lie buried within the inter-tidal sediments of the River Hamble (S. England). Previous archaeological investigations have been hindered by difficult excavation conditions resulting in a poor understanding of the dimensions, shape and degradation state of the hull's deeper structure. This study therefore aimed to image, characterize and reconstruct the buried remains of this vessel using a high-resolution 3D acoustic sub-bottom Chirp system with RTK-GPS positioning capability. The accurate navigation and high-resolution data that were acquired enabled the construction of a full 3D image of the site that not only identified the remains of the wooden hull, but also features buried within it. In addition, the degradation state of these buried wooden remains were investigated by calculating reflection coefficients while a hypothetical larger reconstruction of the Grace Dieu's hull was achieved, through the use of the ShipShape ship design software package.     

Preliminary neutron diffraction study of two fenestrated axes from the ‘Enot Shuni' Bronze Age cemetery (Israel)

Neutron diffraction (ND) analyses of ancient metals show that this method is capable of detecting differences in the inner composition and microstructure of ancient metal objects. Here, ND measurements were conducted on two ‘eye shaped’ axes from the end of the 3rd-beginning of the 2nd millennium BC. The objects were excavated from the ancient cemetery of ‘Enot Shuni' Israel; one is made of bronze and the other of silver. Both artefacts are rare finds, with the silver axe unique in the archaeology of Israel, and therefore had to be analysed locally. For that purpose, a newly assembled diffractometer (KARL) at the IRR-1 of the Nuclear Research Centre (Soreq, Israel) was used. ND measurement on the bronze axe revealed the existence of an α-phase with a range of Cu/Sn ratios (Cu–Sn solid solutions) and some amount of a δ-phase (intermetallic compound of Cu and Sn). The silver axe ND pattern shows the existence of an α-phase (Ag–Cu solid solution) and some amount of copper metal. Our ND data are discussed in comparison with XRF surface measurements and thermal neutron radiography. The results are shedding more light on the in-depth material composition profile, as well as on the objects’ structural and compositional affinities, and help to better understand the production processes and assist in conservation decisions.     

Atlantic salmon, archaeology and climate change in New England

A paucity of archaeological remains of Atlantic salmon in Northeast North America has been cited as evidence that the species may have been present in the region only during and after the Little Ice Age (ca. 1450–1850 AD), one of coldest periods of the Holocene. However, significant problems of preservation, recovery and identification remain. Here, improved methods of identification use vertebra structure to distinguish salmon from trout, and strontium/calcium ratios to differentiate sea-run from landlocked salmon. In addition to the Little Ice Age, Atlantic salmon is identified in tightly dated contexts at 7000–6500 and 3500–3000 calendar years BP, during climate periods that were comparatively warm and wet.
