Stable isotope evidence for palaeodiets in southern Turkmenistan during Historical period and Iron Age

The subsistence patterns of Iron Age and Historical period humans from south-western Turkmenistan have been reconstructed using the carbon and nitrogen isotopic compositions of archaeological faunal and human bones. A qualitative comparison of the isotopic signatures points to a small proportion of ruminant meat and dairy in human diet for both periods. The ranges of proportions of dietary items yielded by a quantitative approach based on concentration dependent mixing models confirm the high proportions of plant food in the average diet, and show little change in the reconstructed diet for both periods. A comparison of results from zooarchaeological and isotopic approaches illustrates their complementarity in subsistence patterns reconstruction.     

Post-Communist Corruption: In a League of its Own?

Conventional wisdom has it that the post-communist countries are in a league of their own with regard to corruption. At first sight, the levels of corruption are, indeed, particularly high in both presently communist and formerly communist countries. However, this generalization dissolves as a mirage when the proper control variables are included into the explanatory model. Countries with a communist past or a communist presence are as corrupt as one would expect based on other structural characteristics such as the level of economic development, a Protestant cultural tradition and the dependency on natural resources. Ceteris paribus, then, the communist legacy has no direct effect on contemporary levels of corruption. At most, it is possible to argue that it has an indirect effect working through the variable of economic development.     

Insights into early Holocene hunter-gatherer mobility on the Peruvian Southern Coast from mollusk gathering seasonality

Quebrada de los Burros (QLB) is an early Archaic coastal archaeological site in southern Peru (∼18.1°S) and the most extensively studied in the area for this period. It was occupied from 10 to 6.5 ka by fishermen also practicing hunting and mollusk gathering. Shell growth lines in 116 individuals of the surf clam Mesodesma donacium were studied to determine the month of their death (±2 months). Our results show that, for the whole occupation period, mollusk gathering was a seasonal activity mainly practiced during austral spring and summer. A change occurred between the early and the middle Holocene: the mollusk gathering season in the middle Holocene occurred ∼3 months earlier in the year than in the older levels. This behavior change could have a cultural origin, rather than dictated by the environment for it is associated with changes in the lithic industry. QLB occupants also hunted herbivores in the nearby lomas ecosystems. These plant communities only grow during the fog season from June to December, suggesting that the site was occupied during this season. A comparison of the span of the mollusk gathering season and the lomas season suggests that, at least during the early Holocene, QLB was occupied all the year round. A permanent freshwater source and the proximity of the sea, the lomas, and raw lithic materials, provided ideal conditions for a permanent occupation. This result reveals a strategy based on a seasonal alternation between marine and terrestrial resources exploitation.

Mammalian erythrocyte preservation in a 3500-year-old Egyptian pot

A ca. 3500-year-old Egyptian pot from the Fayoum site of Gurob contains ethmoid bones characteristic of the sinuses and morphological remains of erythrocytes. The pot contents are interpreted as the remnants of an embalmers studio, and substantiate records of mummification.     

It’s never too late to join the revolution! – Enabling new modes of production in the contemporary Danish food system

ABSTRACT

The Danish food system has undergone a transition in the past 10–20 years, in which new quality conventions have evolved. Examples include increasing organic production and consumption, and increasing interest in local food, experience, community, taste and gastronomy. This article explores what influences if and how these new food trends are expressed in the food system. We conduct a comparative case study involving three product categories: craft beer, specialty flour and organic broilers. Craft beer and specialty flour have undergone a revolution, in which new flavours, products, practices and social relations are generated; by contrast, organic broilers have remained a relatively stable product category. The case studies demonstrate that the revolution is not just taking place in one domain, but it implies a multidimensional reconfiguration of the food system where an emphasis on multiple quality aspects and diversification of the product category is important. However, food trends are not the invention of the individual producer, but serve as common conventions that products can be related to, although their interpretation is not pre-given. In addition, a transition presupposes a shared vision and a coordination of activities among the actors in the food system or the mobilization of new actors who share this vision.
