Lost writing uncovered by laser two-photon fluorescence provides a terminus post quem for Roman colonization of Hispania Citerior

In this work, two-photon absorption fluorescence is used as a non-destructive method to detect the presence of paint upon an archaeological sample. The objective was to recover writing that, due to the discoloration caused by the passage of the time, was barely readable. The technique has been successfully applied to determine the consular date painted upon the neck of a Dressel 1A amphora found in the Roman village of Iesso (Guissona), in Catalonia. The identification of the consular date provides a terminus post quem for the foundation date for the city as well as a starting date for the Roman colonization of Hispania Citerior.     

Ecological Inference and Spatial Variation of Individual Behavior: National Divide and Elections in Catalonia

When in geography one reconstructs individual behavior starting from aggregated data through ecological inference, a crucial aspect is the spatial variation of individual behavior. Basic ecological inference methods treat areas as if they were all exchangeable, which in geographical applications is questionable due to the existence of contextual effects that relate to area location and induce spatial dependence. Here that assumption is avoided by basing ecological inference on a model that simultaneously does a cluster analysis, grouping together areas with similar individual behavior, and an ecological inference analysis in each cluster, estimating the individual behavior in the areas of each group. That allows one to capture most of the spatial dependence and summarize the individual behavior at a local level through the behavior estimated for each cluster. This approach is used to investigate vote switching in Catalonia, where voters split across a national allegiance divide on top of the ideological divide. That leads to Catalans having a lot of options to choose from, and to them voting differently depending on whether the election is for the Catalan parliament or for the Spanish parliament. To investigate that, the results in the two most recent pairs of such elections are analyzed by simultaneously clustering areas based on the similarity of their vote and vote switch patterns, and estimating one vote switch pattern for each cluster. As a result, Catalonia is partitioned into four clusters that have a strong spatial structure, with all the areas in the same cluster having similar demographic composition. The estimated vote switch patterns are quite different across clusters but very similar across pairs of elections, and they help assess how the differential voter turnout and the strategic dual vote effects vary in space.     

The Anthropogenic Use of Firewood During the European Middle Pleistocene: Charcoal Evidence from Levels XIII and XI of Bolomor Cave,Eastern Iberia (230–160 ka)

Human control of fire is a widely debated issue in the field of Palaeolithic archaeology, since it involved significant technological innovations for human subsistence. Although fire evidence has been the subject of intense debate regarding its natural or anthropogenic nature, most authors agree that combustion structures represent the most direct evidence of human control of fire. Wood charcoal fragments from these contexts represent the fuel remains that result from humans’ collection of firewood, which means they can reveal significant behavioural and palaeoenvironmental information relevant to our understanding of Middle Palaeolithic societies. In this work, we present anthracological data derived from combustion structure 2 (level XIII, ca. 230?ka, MIS 7) and combustion structure 4 (level XI, ca. 160?ka, MIS 6) from Bolomor Cave, which are chronologically among the earliest combustion structures found in Europe. The present work discusses how the presence of black pine and / or scots pine in both levels sheds light on the characterisation of the local landscape. Additional analyses focussing on the pre- and post-depositional processes affecting charcoal preservation point to biodegradation patterns. The aim of this work is to provide the first discussion concerning the anthracological data derived from Bolomor Cave in order to contribute to the general debate regarding the use of fire during the European Middle Pleistocene.     

Osteological and paleodietary investigation of burials from Cova de la Pastora,Alicante, Spain

We present results of osteological and isotopic analyses of human remains from Cova de la Pastora (Alcoi, Alicante, Spain) and discuss the implications in light of a new sequence of radiocarbon dates indicating that the cave was used as a burial site in the Late Neolithic (ca. 3800–3000 cal BC), Chalcolithic (ca. 3000–2500 cal BC), Bell Beaker Transition (Horizonte Campaniforme Transicional - HCT; ca. 2500–2200 cal BC) and the Bronze Age (ca. 2200–1500 cal BC). Similarities in stable isotopic values of C and N indicate little variation in subsistence between men and women, and a similar nutritional base from the Late Neolithic to the Bronze Age. This pattern of stability is augmented by evidence of trauma and disease found on numerous skulls in the collection. Since no clear associations of specific grave goods with certain individuals based on sex or age could be determined, the only suggestion of social inequality lies in the burial practice itself, where certain individuals were interred in caves while others were not.
