An Ethnoarchaeological Study on Anthropic Markers from a Shell-midden in Tierra del Fuego (Southern Argentina): Lanashuaia II

ABSTRACT

For many years the identification of activity areas has been carried out through the spatial distribution of lithics, zooarchaeological remains and specific features such as fireplaces. However, these data are rarely combined and integrated with results from specific analytical techniques such as phytoliths, organic matter, carbonates and multielemental analysis. This research presents the first results of an intrasite spatial analysis on a layer from the site Lanashuaia II, a shell-midden located on the Beagle Channel coast (Tierra del Fuego, Argentina). Ethnoarchaeology is used as a methodological tool to give content to the concept of anthropic markers by means of formulating archaeological hypothesis on the basis of ethnological information. This paper presents the application of specific anthropic markers, which have been designed and applied to identify ashy remains and waste areas through different combinations of proxies. The results show how an approach that integrates different techniques enhances data interpretation and allows to give visibility to activities that may not leave visible evidences.     

Alternative Food Economies and Transformative Politics in Times of Crisis: Insights from the Basque Country and Greece

Why and how do alternative economies emerge, how do they develop and what is their contribution, if any, to transformative politics? Alternative economies proliferate in the countries worse hit by economic crisis and austerity, such as Spain or Greece. Yet the existing literature is stuck in a counter‐productive division between celebration and critique. We move beyond this division applying philosopher Daniel Bensaïd's understanding of politics to two alternative food economies, one in the Basque Country and one in Greece. We illuminate the activist strategies and specific conjunctures within which the two alternatives emerged and explain how they develop in the face of political‐economic barriers. Alternative economies, we conclude, can be transformational when they are inserted in activist strategies directed to extend conflict, social struggles and challenge the capital–state nexus.     

The Macro‐Regional Scale of Silver Production in Iberia During the First Millennium BC in the Context of Mediterranean Contacts

The extraction of silver has traditionally been considered as one of the main incentives for the Phoenician expansion throughout the Mediterranean and their settlement in Iberia. In this paper, we approach the organization of silver production in Iberia during the Early Iron Age through the study of the evidence of production currently available and the development of Lead Isotope Analysis (LIA). Previous results (Hunt 2003; Stos Gale 2001; Kassianidou 1992) are considered in the light of new data. The extraction of silver from complex minerals noticeably intensifies in south‐west Iberia. Imports of exogenous lead, needed for the extraction of silver from these complex minerals, are evident. Supplies of lead come in from other regions of Iberia, such as Gádor, Cartagena/Mazarrón, Linares or even the mining district of Molar‐Belmunt‐Falset (MBF) in Catalonia. This picture reveals that the organization of silver production was much more complex than initially thought, with the articulation of an exchange network of raw materials at a macro‐territorial scale embracing almost all Iberia. The socioeconomic implications that control of these networks of lead distribution could have had are also discussed.     

Intra-skeletal variability in trace elemental content of Precolumbian Chupicuaro human bones: the record of post-mortem alteration and a tool for palaeodietary reconstruction

This study applies an intra-skeletal sampling strategy to examine post-mortem alteration of archaeological human bone from west Mexico, and to reconstruct ancient diet. Human bone from the Chupicuaro culture (Mexico, Preclassic period) constitutes an ideal material with which to examine subsistence strategies because the specific hydrothermal environment in which the population lived would have provided certain food components (hydrothermal waters and carbonates) with distinct signature in Ca, Mg, F, Li, Sr, Mn, V and U values. Four to ten samples were taken from the long bones of six skeletons. Bone trace element content (Ca, P, F, Mn, Mg, Na, Li, V, Zn, Rb, Sr, Ba, Y, La, Ce, Nd, Th, U) and bone alteration parameters (crystallinity, organic matter and secondary calcite content) were analysed at the intra-skeletal level. Stable isotopic signatures (bone δ¹³C and δ¹⁸O_carbonate) and histological analyses were also performed on a single bone from each individual. Results indicate that all of the skeletons were affected by post-mortem mineralogical, structural and geochemical transformations. Biological bone δ¹³C values seem preserved for most of the individuals but an increase in crystallinity accompanies depletion in bone δ¹⁸O values. The combination of bone alteration parameters with bone elemental content shows that in this very specific context, a widespread dissolution-recrystallisation is unlikely. Of the hydrothermal tracers, Sr, F and Li were of particular interest because their retention in living tissues is related to the amount ingested. The intra-skeletal Li content does not reveal any pattern but Li depletion is not excluded. In contrast, Sr and F show a progressive intra-skeletal diagenetic enrichment likely due to gradual diffusion–adsorption processes. The bones with the lowest concentrations in these elements are assumed to yield the best representative ante-mortem values. The signal extracted from each skeleton, a very unusually high bone Sr, F and Li content, is interpreted as reflecting the consumption of the local hydrothermal products, which are also enriched in these elements.     

Inherited memory,social learning,and resilience: lessons from Spain's Great Blizzard of 1888

The snowstorms that affected the Cantabrian Mountains in the winter of 1888 caused unprecedented damage, and the absence of a “resilient approach” to this episode had several consequences worth further consideration. In this study, we explored interconnections between and among memory, social learning, and resilience by surveying the affected landscapes, conducting interviews with current residents, and reviewing historical sources such as press archives. The mixed method has enabled us to examine the construction and transmission of respondents' memories and to link those narratives to our reading of the presence or absence of risk mitigation actions—especially against snow avalanches. Our analysis has established that the 1888 snowstorms are remembered down the decades in ways that downplay risk, neglect social learning and changes to community practices and capacities to cope with uncertainties, and fail to shape preventive measures against future disasters. These insights have relevance for those interested in how archival research, field observations, and contemporaneous interviews can aid understandings of inherited memory, social learning, and resilience.     

Testing for Spatial Independence Using Similarity Relations

In this article, we construct new, simple, and nonparametric tests for spatial independence using symbolic analysis. An important aspect is that the tests are free of a priori assumptions about the functional form of dependence, making them especially suitable in situations where the dependence is nonlinear. We define the concept of a similarity relation, which is used to keep track of similarity between neighboring observations. This similarity count is used to construct new statistical tests based on both random permutation simulations and derived asymptotic distributions. We include a Monte Carlo study to better illustrate the properties and the behavior of the new tests under several synthetically generated processes. Apart from being competitive compared with other nonparametric and parametric tests, results underline the outstanding power of the new tests for nonlinear‐dependent spatial processes.
