Sur les traces de Cortés: L'expédition du Mexique d'après Le Monde illustré

Unlike L'Illustration, with which it competed under the Second Empire, the weekly Le Monde illustré, which first appeared in 1857 and which was protected by the imperial government, did not count among the political newspapers overtaxed under Napoléon the Third's repressive regime. For this reason, it made great strides thanks to its blind allegiance to a French imperialism that had asserted its authority during the Crimean war, but which spent itself during the war against Juárez and his republican partisans in Mexico. While the French liberal press criticized the Second Empire foreign policy, Le Monde illustré persisted in turning the Mexican war into an antijuarist pacification favorable to a new Latin colonial empire, as well as to an application of the Saint-Simonian doctrine on Mexican industry and economy. In order to achieve this, the illustrated reports on the expeditionary force, military operations, and French victories were a warmongering that aimed to place this campaign in the afterglow of the conquistadors' era, as well as to idealize the imperial army as a symbol of the French nation.     

Hunter-gatherer tobacco smoking: earliest evidence from the Pacific Northwest Coast of North America

Chemical analysis of residue extracted from stone pipes and pipe fragments excavated at sites in the southern Pacific Northwest Coast of North America demonstrate that hunter-gatherers smoked the psychostimulant tobacco (Nicotiana sp.) by at least AD 860. Non-farming ethno-historic Native Americans throughout the west gathered and sometimes cultivated tobacco for ritual and religious purposes, but until now the antiquity of the practice on this part of the continent was unknown. Method validation includes chemical characterization of a suite of smoke plants and experimental reproduction of “smoked” pipe chemistry; results indicate biomarkers are traceable for several species commonly smoked by ethnographic native peoples, including tobacco (nicotine, cotinine), tree tobacco (anabasine), and kinnikinnick (arbutin). Developed methods—where residue is extracted directly from the stone or clay matrix of whole and fragmentary archaeological pipes—may be applied in similar studies investigating the spread and use of ritual smoke plants in the ancient Americas and elsewhere.     

Tools for Predicting Damage to Archaeological Sites Caused by One-Dimensional Loading

Tools are developed to predict damage to archaeological remains caused by the construction of line infrastructure on soft soil. They are based on numerical modelling and laboratory testing supported by X-ray microcomputed tomographic observations, and micromorphological analyses of thin sections. They have been validated for one-dimensional (1D) loading at two sites in the Netherlands where soil has been placed on top of organic layers rich in ecofacts and overlaying Pleistocene sands.

Numerical prediction of the deformation of soft layers underneath an embankment remains a challenge for geo-technical engineers. Errors on surface settlement prediction reach ±15% of the measured total settlement.

Laboratory observations show that vulnerable artefacts can get crushed when packed loosely in pure assemblies under 1D loading equivalent to less than 5 m of sand. Fragmentation is assimilated to loss of archaeological value as it compromises recovery during sieving. Embedment in a sandy or a very compressible organic matrix has a beneficial effect on the resistance of ecofacts. Embedded ecofacts can resist a load of more than 12 m of sand. Flattening and re-orientation of soft plant remains occur during 1D loading without microscopic damage of tissues.     

Network Autocorrelation

Even though Cliff and Ord (1969) do not question "network autocorrelation," their paper contains an interesting ambiguity that is here discussed. Hence, this article aims at discussing the problem of spatial autocorrelation in (perhaps preferably on) a network as well as at giving an overview of the existing relevant literature. A typology of network autocorrelations is suggested and it is hoped that this discussion initiates debates and points to new research challenges.
