The shrinkage cracks and the diameter of the log: a experimental approach toward fuel management by Patagonian hunter-gatherer (Paredón Lanfré site. Río Negro Province,Argentin)

The anthracological study of Paredón Lanfré (Patagonia, Argentina) highlights the presence of radial cracks with a marked difference between the percentage of affected coniferous charcoal (Fitzroya cupressoides and Austrocedrus chilensis) compared to the angiosperms (e.g., Nothofagus antarctica and Nothofagus dombeyi). The aim of this work was to obtain experimental comparison data from two Patagonian conifers to understand the prehistoric combustion behavior of the region. These results showed a discrepancy between the average of shrinkage cracks made with green wood fires and those with dry wood fires. The study of the caliber of charcoal recovered from Paredón Lanfré showed significant differences between the samples of F. cupressoides and A. chilensis. The calculation of correlation between size and shrinkage cracks suggests for both species that the size is not related to the number of registered shrinkage cracks in charcoal studied. Therefore, the gauge would not be a variable which could influence the presence of shrinkage cracks in the charcoal. Consequently, the difference of average shrinkage cracks between the two specimens may result from another variable that remains to be identified.     

High‐boron and High‐alumina Middle Byzantine (10th–12th Century ce) Glass Bracelets: A Western Anatolian Glass Industry

The trace element boron is present in most ancient glasses as an impurity, and high boron (≥ 300 ppm) marks raw material sources that are geologically specific and relatively uncommon. Recent analyses of Byzantine glass with high boron contents suggest that glass‐making was not limited to the traditional regions of the Levant and Egypt, and a production origin in or near western Anatolia is proposed. Glass bracelets from ?i?n al‐Tīnāt in southern Turkey give fresh evidence for the production and circulation of high‐boron glasses that closely correlates with object typology. The patterning of findspots suggests that high‐boron glass was closely connected to the Byzantine world.     

Le déplacement des pôles du théâtre francophone: Malcolm de Chazal et l’arrière-scène tibétaine

Acclaimed by the Parisian Surrealist circles in 1948, Malcolm de Chazal, the French-speaking Mauritian writer and painter, opted for unchartered literary territories in his subsequent works. In the 1950s, he wrote a collection of dramas that tended to decentre his writing practice towards Asian perspectives. References to Indo-Mauritian culture assuredly provided him with a major source of inspiration to deliver a culturally hybrid theatre. Yet Tibet may seem at first a rather unlikely referent in his work. One can nevertheless demonstrate by comparing the author’s numerous references to Tibet that it is not only meaningful in his entire work but also that it is a central and neglected aspect of his geo-literary agenda.     

Institutional and Policy Responses to Uncertainty in Environmental Policy: A Comparison of Dutch and U.S. Styles

Uncertainties regarding problem definition and policy response are an endemic pan of environmental decisionmaking. Some standard responses to uncertainty in decisionmaking are analyzed and then used to suggest the importance of learning-oriented policy processes in open, flexible, and adaptive institutional environments. The institutional and policy responses to both types of uncertainties are explored in two different institutional settings: the consensus-oriented setting of the Netherlands and the more adversarial and pluralistic context of the United States. The examination displays tensions accompanying learning-oriented environmental policymaking and the complex impact of institutional environments. Conclusions sketch implications for how to accommodate learning-oriented environmental policy processes.     

The Intentional Use of Lead–tin Orange in Indian Islamic Glazes and Its Preliminary Characterization

We describe the historical appearance, composition and texture of a little‐known orange pigment in 17th‐century northern India. The pigment shares similarities with lead–tin yellow type II, but has between 6 and 7 wt% zinc oxide instead of silica as a minor element in its structure, in addition to the dominant lead and tin oxide. The consistency of its occurrence and composition across several important and highly decorated monuments and relatively wide chronological and geographical ranges of use indicate the controlled and intentional production of this pigment. We propose to use the name lead–tin orange for this material, indicating its similarity to lead–tin yellow but highlighting its independent character and distinct colour.
