Intrinsic or extrinsic population growth in Iron Age northeast Thailand? The evidence from isotopic analysis

Here we present strontium, carbon and oxygen isotope measurements from the tooth enamel of 34 adults from Noen U-Loke, an Iron Age site (c. 300BC–500AD) in the Upper Mun River Valley (UMRV), northeast Thailand. The Mun Valley is rich in archaeological sites from the Bronze Age to the Iron Age, with evidence for changes in social complexity, new technologies and population growth. Whether the population growth in the UMRV was intrinsic, as opposed to extrinsically due to immigration, is an unresolved question. Our results suggest low levels of long-distance immigration, with only three (two females, one male) of the thirty-four individuals as probable immigrants from outside the region. We discuss the implications of this result as a contribution to longer-term investigations of population growth, human mobility and fertility during this prehistoric period of substantial societal changes in mainland Southeast Asia.     

The relative effects of core surface morphology on flake shape and other attributes

It is long been thought that many flake attributes, including both size and shape, are largely due to the morphology of a core’s flaking surface, yet this has never been tested under strictly controlled conditions. Using molded glass cores with surface morphologies that highly resemble prehistoric ones, this experiment demonstrates that while core surface morphology does exhibit some influence on flake size and shape, a high degree of variation in flakes produced with the same core surface morphology shows that the effects of other independent variables, such as exterior platform angle and platform depth, have an even stronger effect. A major implication of these results is that current approaches to reconstruct prehistoric knapping strategies are overlooking significant sources of variation.     

Understanding ceramic variability: an archaeometrical interpretation of the Classical and Hellenistic ceramics at Düzen Tepe and Sagalassos (Southwest Turkey)

Within the aim of contributing to the artisanal craft history at Sagalassos (SW-Turkey), an archaeometric programme including thin section analysis, ICP-MS and multivariate statistics was developed to define the variability on a provenance and/or technological scale of the Classical/Hellenistic ceramic assemblage of Sagalassos and Düzen Tepe. The obtained data were used to evaluate the extent and variation of local pottery production. Petrographic and geochemical analysis as a grouping technique proves to be conditional for documenting the variation in ceramic wares present on both archaeological sites. Elemental evidence supports local production activities between Classical and Hellenistic times, documenting a deliberate change in treatment of raw materials during the Late Hellenistic period in function of ware groups.     

Obsidian provenance for prehistoric complexes in the Amur River basin (Russian Far East)

The sources of high quality volcanic glass (obsidian) for archaeological complexes in the Amur River basin of the Russian Far East have been established, based on geochemical analyses by neutron activation and X-ray fluorescence of both ‘geological’ (primary sources) and ‘archaeological’ (artifacts from the Neolithic and Early Iron Age cultural complexes) specimens. A major obsidian source identified as the Obluchie Plateau, located in the middle course of the Amur River, was found to be responsible for supplying the entire middle and lower parts of the Amur River basin during prehistory. The source has been carefully studied and sampled for the first time. Minor use of three other sources was established for the lower part of the Amur River basin. Obsidian from the Basaltic Plateau source, located in the neighboring Primorye (Maritime) Province, was found at two sites of the Initial Neolithic (dated to ca. 11,000–12,500 BP). At two other sites from the same time period, obsidian from a still unknown source called “Samarga” was established. At the Suchu Island site of the Early Neolithic (dated to ca. 7200–8600 BP), obsidian from the ‘remote’ source of Shirataki (Shirataki-A sub-source) on Hokkaido Island (Japan) was identified. The range of obsidian transport in the Amur River basin was from 50 to 750 km within the basin, and from 550 to 850 km in relation to the ‘remote’ sources at the Basaltic Plateau and Shirataki-A located outside the Amur River valley. The long-distance transport/exchange of obsidian in the Amur River basin in prehistory has now been securely established.     

A calf for all seasons? The potential of stable isotope analysis to investigate prehistoric husbandry practices

The Early Bronze Age barrows at Irthlingborough and Gayhurst in central England are notable for the large number of cattle (Bos taurus) remains associated with their human Beaker burials. Previous work using strontium isotope analysis has indicated that most of the cattle analysed, and one aurochs (Bos primigenius), were of local origin [Towers, J., Montgomery, J., Evans, J., Jay, M., Parker Pearson, M., 2010. An investigation of the origins of cattle and aurochs deposited in the Early Bronze Age barrows at Gayhurst and Irthlingborough. Journal of Archaeological Science 37, 508–515.]. In this study, stable isotope analysis of enamel and bone was carried out to investigate whether the mature cattle had experienced similar husbandry practices, climate and environment. Bulk carbon, nitrogen and sulphur isotope analysis of collagen suggested most were consuming similar sources of plant protein from environments probably local to the sites and this was supported by high resolution intra-enamel carbon isotope profiles. Oxygen isotope profiles indicated the aurochs and most of the cattle experienced similar climatic regimes: the only exception being an animal with a non-local strontium isotope ratio. However, a comparison of seasonality profiles of the local animals using estimated tooth formation times showed that there was no consistency in season of birth: the animals appeared to have been born throughout the year. Cattle can breed throughout the year but it requires considerable human effort and intervention to successfully overwinter young stock; it is therefore unlikely to have been carried out without good reason and benefit if winters were harsh. One reason is to ensure a continuous supply of milk. Measuring oxygen isotope profiles to identify year-round calving may thus be a potential indicator of dairying economies.

Laboratory and in situ assays of digital image analysis based protocols for biodeteriorated rock and mural paintings recording

Rock art paintings, and in general mural paintings, are one of the many elements of cultural heritage complex systems. As the different elements of a system have diverse spatial positions, spatial recording allows understanding their interactions. Thus, a useful approach to mural paintings recording is to understand it as a microcartography issue, managing each element of the system as a cartographic coverage.     

Chemical and lead isotope analysis of some lead-barium glass wares from the Warring States Period,unearthed from Chu tombs in Changde City,Hunan Province,China

In the context of the present study, we have conducted chemical and lead isotope analyses on twelve ancient glass samples unearthed from Chu tombs in Changde City, Hunan Province. The results of the chemical analysis of these samples show that all samples are PbO–BaO–SiO₂ glasses, thus indicating that they are all traditional ancient Chinese glasses. The chemical results also suggest that all Bi wares may either share a common source or were produced according to similar recipes. In turn, the eye beads are different from the Bi wares for their distinct chemical composition. The chemical results indicate that silica, lead-bearing material, barium-bearing material, and sodium/lime-bearing material are the main independent components of the raw materials employed in the production of these glass wares.     

Hafted armatures and multi-component tool design at the Micoquian site of Inden-Altdorf,Germany

Excavation of the Micoquian site Inden-Altdorf (Weisweiler-124) near the former German capital Bonn in western Germany has revealed the first valid open-site habitation features with hut-like structures and associated hearths for the Middle Palaeolithic in Central Europe. It has been dated to the Eemian interglacial (OIS 5e), a warm interglacial between 128 and 115 ka BP. Various wear traces and especially organic residues have been detected on a large number of stone tools using microscopic use-wear analysis of lithics recovered from the site. A multi-level analysis developed through an experimental framework and archaeological study using optical light microscopes, scanning electron microscopes and energy-dispersive X-ray microprobes identified the adhering residues as birch pitch. Birch pitch is the oldest synthetically produced material and was used as an adhesive to attach lithic implements to wooden shafts. While such hafting technology is commonly associated with modern humans in the Upper Palaeolithic, the birch pitch residues found on the Micoquian tools of Inden-Altdorf suggest that hafting technologies and the frequent use of multi-component tools already existed in the Middle Palaeolithic, c. 120 ka BP in central Europe.     

Materialist State Theory and the Transnationalization of the Capitalist State

Abstract: In contrast to assertions that the capitalist state is either losing control or that it has returned, this article argues that during the last two decades the state itself has been reshaped. To understand the processes that the capitalist state is exposed to it is necessary to conceive of it as a series of form‐specific practices. Which practices form “the state” is not a result of pre‐given institutions but of conflicts and struggles. The capitalist state, separated as it is from the relations of production, must not be made synonymous with the national state. Only as a result of certain relations of force does bourgeois rule acquire the form of the national state. These relations between classes are currently being dissolved by the ruling classes. The capitalist state is being reorganized and is constructing new elements of a transnational network state, whilst the state itself is governed through new techniques—that is, those of governance.
