Iron age occupation in the Méma region,Mali

The recent archaeological campaign (regional site survey and excavations at the mound complex of Akumbu) has demonstrated that the Méma, a dry Sahelian region with a scattered population, was intensively occupied during the Iron Age. This intense occupation, certainly associated with better environmental conditions, extends back to the Late Stone Age. During the regional survey more than 100 Iron Age sites and nearly 30 Late Stone Age sites were identified; their size, surface material and features, and location on geomorphological zones were recorded. A series of radiocarbon dates spanning the fourth to fourteenth centuries ad obtained from the excavations at the Iron Age mound complex of Akumbu and a preliminary analysis of the pottery from both the excavations and the survey permitted the determination of a broad chronology of occupation. Numerous slag heaps (associated with smelting furnace remains) found during the survey and imported goods uncovered during the excavations at Akumbu indicate that both iron production and long-distance trade played an important role in the Méma economy.

Résumé Une campagne archéologique (reconnaissance et fouilles) exécutée en 1989–1990 a montré que le Méma, une région sahelienne de grande sécheresse à population actuellement éparse, était intensément peuplé pendant la période de l'Age du Fer. Cette intense occupation, certainement liée à de meilleures conditions climatiques, semble remonter à la période du néolithique. Au cours de la reconnaissance, conduite à l'échelle régionale, plus d'une centaine de sites datant de l'Age du Fer et environ une trentaine de sites néolithiques furent identifiés, enregistrés et décrits en termes de leurs dimensions, matériels et caractéristiques de surface, et environnement. Une série de datations au radiocarbone, obtenue lors de la fouille sur le complexe de buttes d'habitat de Akumbu, dans la partie ouest du Méma, indique une occupation s'étendant du quatrième siècle au quatorzième siècle de notre ère. La découverte d'imposants amas de scories, associés à des restes de hauts fourneaux, et objets exotiques trouvés lors des fouilles à Akumbu, attestent que la production de fer et le commerce à longue distance jouaient tous les deux un important rôle dans l'économie du Méma.

     

L'«École de l'ETH» dans l'œuvre de Gaston Bachelard

We retrace here spectral presence in the work of Gaston Bachelard which we call «The School of the ETH». We have chosen three fundamental figures: hermann Weyl, Wolfgang Pauli and Gustave Juvet. For the first one, we consider his central and permanent place in the Bachelardian constitution of a philosophy which seeks to be at the height of the new «physical geometry» rigorously constructed in a Riemannian spirit. As for Pauli, we show an unsuspected affinity which is backed up by the remarkable analyses brought to it by philosophy: from the urgent construction of a «quantic metaphysics», founded on the implications of aPauli principle well understood, to the idea of a «metaphysical particle», going on to the decisive and so promising stakes of the «postulate of non-analysis». In the framework of this convergent polyconstruction of the «surrationalist», enterprise, we treat the third figure, less known but equally important, of the mathematician-philosopher Gustave Juvet.     

Esquisses géographiques des récits cinématographiques Canadiens contemporains

Films carry an original geographic discourse. Beyond the vision of an author, they often reflect a society's perspective on territories. The goal of this research is to study the geographic discourse developed by Canadian cinema through an analysis of the places structuring Canadian cinematographic narratives. This analysis is based on the systematic study of a selection of 46 contemporary Canadian films. These films have been transformed into a database of 2200 places using an original geographic reading grid. Analysis of these places identifies the existence of territories under‐ and over‐represented by Canadian cinema, as well as territories of consensus and divergence that exist between different categories of Canadian cinema such as Quebecois, anglophone, and hybrid. Some interesting results include the general lack of interest in the southern hemisphere—notably Latin America—as well as in the Nordic territories (outside of First Nations cinema). It is also interesting to note the quasi‐absence of Vancouver on the screen, while Toronto and the United States appear recurrently. But the most striking result is probably the profound divergence in the way Canadian cinema treats the province of Quebec in general, and the city of Montreal in particular. Montreal is indeed the perfect example of a space of divergence: the city is heavily represented in Quebecois films, but completely ignored in the rest of Canadian cinematographic production. This deep opposition illustrates the importance of downtown Montreal as a symbolic space of Quebec national identity.
