Continental Patterns in Stone Tools: A Technological and Biplot-Based Comparison of Early Late Pleistocene Assemblages from Northern and Southern Africa

The technology of the end products i.e. blades and points in Late Pleistocene stone artefact assemblages from Klasies River, South Africa, and the Nile Valley, Egypt, are compared. The comparison includes univariate and multivariate analysis of metrical attributes enhanced by graphical biplot displays. The end products in these assemblages are either dominantly points or blades and this is related to the core reduction strategy adopted. The MSA 11 from Klasies River and the Nubian Complex industry from the Nile Valley are point industries made in the Levallois tradition, while the MSA 1 from Klasies River and the Taramsan from the Nile Valley may be non-Levallois or adapted Levallois blade industries. Dating of the assemblages shows the changes between dominant core reduction strategies are sequential and time restricted in both South and North Africa. It is concluded that variability of the same kind occurs in Middle Stone Age and Middle Palaeolithic assemblages south and north of the Sahara in the early Late Pleistocene.Dans cet article, les technologies des produits recherchés, des lames et des pointes, pour certains ensembles lithiques de Klasies River, Afrique du Sud et la Vallée du Nil, Egypte, sont comparées. Cette comparaison implique des analyses univariées et multivariées de variables métriques biplot. Les produits recherchés sont bien des pointes que des lames, selon les stratégies dexploitation adoptées. Le MSA II de Klasies River et le Complexe nubien de la Vallée du Nil sont des industries à pointes issues de la tradition Levallois. Par contre, le MSA I de Klasies River et le Taramsien de la Vallée du Nil évoquent une technologie de production non-Levallois ou Levallois modifiée. Les éléments de datation disponibles indiquent que les changements dans la prépondérance des stratégies dexploitation senchaînent dans une séquence chronologique bien identifiable, aussibien dans lAfrique du Sud que lAfrique du Nord. On arrive à la conclusion quune variabilité du même caractère est attestée dans les ensembles du Middle Stone Age et du Paléolithique moyen au sud et au nord du Sahara, pendant le Pléistocène supérieur ancien.     

Is Archaeology Developmental?

Archéologie et développement semblent deux notions fort éloignées l'une de l'autre. La première évoque une recherche fondamentale, pure alors que la deuxième parle de santé, économie, éducation, agriculture, pêche, équipement, transports, communications, etc. . . Et pourtant elles se rejoignent dans le bien-être aussi bien matériel que culturel qu'elles sont supposées apporter aux peuples auxquels elles s'adressent. En effet, si elles introduisent, importent des connaissances, des savoirs des techniques et des machines permettant de mieux maîtriser le monde, nourrir et élever les peuples, ces connaissances interfèrent avec la façon dont ceux-ci vivent et ceci depuis longtemps, la façon dont ceux-ci pensent leurs vies et le monde: philosophies, religions, histoires et coutumes dont on pense se débarrasser en les considérant fausses ou irrationnelles. Ainsi apprend-on que laTerre est ronde et tourne autour du soleil, que nous sommes faits de particules, et qu'il faut s'incliner devant les lois de l'évolution. La Science nous a appris et nous apprend toujours la Vérité sur le monde qui nous entoure bien qu'elle ait donné les moyens intellectuels et matériels aux plus grands massacres que l'Histoire ait connus et bien qu'il ne se passe pas de mois sans catastrophes climatiques, industrielles, politiques ou culturelles ou sans sinistres prévisions, comme le nivellement du mondialisme! Ainsi un des problèmes centraux du développement, illustré ici par une réflexion historico-archéologique, réside dans le dialogue (ou son absence) entre ces deux domaines de connaissance: le scientifique, le moderne et l'autochtone, l'ethnique, le non-moderne. Si l'on veut que ce développement concerne la majorité de chaque peuple impliqué, il est de la plus haute importance de s'interroger sur les modalités des échanges et choix de savoirs, leur équilibre et les raisons profondes des désaccords planétaires à ce sujet. Sous cette condition, le Développement deviendra vraiment démocratique.Archaeology and development seem widely separated notions. The former evokes fundamental pure research whereas the latter talks about health, economics, education, agriculture, fishery, equipment, transports, communications, and so on. Nevertheless both focus on the well-being as well material as cultural which they are supposed to bring to people. In fact if they input and import knowledge, technologies and machineries allowing a better mastering of the world, together with feeding and educating people, both development and archaeology interfere with the ways in which people live and many of the things they believe: philosophies, religions, histories, and customs that become defined as false or irrational. Thus we are taught that the Earth is round and revolves around the sun, that we are made of particles, and that we have to bow in front of the laws of evolution. Science taught us Truth and still does, a truth that provided the intellectual and material means for the worst massacres of history. Thus one of the central problems of development, herein illustrated by a historico-archaeological reflection, lies in dialogue (or its absence) between these two knowledge domains: the scientific, modern and the autochtonous, ethnic, nonmodern. If development projects are to benefit all, it is of the utmost importance to wonder about the exchanges and choices of knowledge, their balance, and the deep meanings of globalization. Under such conditions, development will become really democratic.     

A laboratory cave for the study of wall degradation in rock art caves: an implementation in the Vézère area

The aim of this proposal is to present an original approach to the study and preservation of rock art caves. A multidisciplinary study of cave wall alteration will be performed to understand the impact of environmental context on the evolution of wall surfaces. The approach involves the choice of a cave with characteristics similar to painted caves in the studied area (Vézère Valley in Dordogne, France): e.g., cave wall alteration, lithology, morphology, etc. This selected cave is intended to become a laboratory cave, monitored for the acquisition of chemical, physical and biological environmental data on bedrock, air and fluids along with their characteristics. A cave without art or archaeological interest has been chosen specifically to conduct experiments, to make in situ analysis and to obtain samples. The results are to be completed by specific observations in several other caves and compiled in a database.     

European developments in strategic spatial planning

Strategic spatial planning which takes an integrated approach to the development of a territory seemed to go out of fashion, but now there are signs that it is being re‐established. This paper explores these developments using case studies from 10 European countries. The analysis uses an ‘institutionalist’ approach, which examines how the ‘agency’ of spatial planning practices responds to the ‘structure’ of contextual forces, at the same time influencing that structure. The ‘driving forces’ which are influencing strategic spatial planning are investigated, as are two aspects of the changes in spatial planning: institutional relations and policy agendas. The conclusions are that—at least in the case studies—there is a movement in the institutional relations towards horizontal articulation, territorial logic, and negotiative forms. Policy agendas too are changing, becoming more selective and using new conceptions of space and place. Those institutional developments, however, are not necessarily being translated into territorially‐integrated policy (as distinct from functional/sectoral policy). That translation appears to require simultaneous re‐framing of relational resources (trust, social capital), knowledge resources (intellectual capital), linked to strong mobilization efforts (political capital). The cases considered varied significantly in how far that had been done. Where it had, strategic spatial plan‐making practices were playing a key role in developing institutional territorial integration and re‐invigorating territorial identities.     

L’impossible constitution d’une théorie générale des machines ?

Three projects on the theories of machines are presented: “mecanology” of the architect Jacques Laffite (1932) inspired by biological evolution; “mecanical analysis ” of Louis Couffignal, a specialist in computing machines (1938), which pre figures functional analysis, and the algebraic theory of machines by the mathematician Jacques Riguet (beginning of the 1950’s). During those years, the three men are members of the Circle of Cybernetic Studies. The article focuses on the dialogue between projects, the axes of unification and divergence, and the styles, strategies and postulates of these three candidates, for generalization converging toward the reference constituted by cybernetics.     

La France n'accepte pas de payer le prix de ses ambitions

This article takes as its starting point the massive changes in French political, economic and social life since the 1960s, as part of a process of internationalisation involving world trade and the commitments of European integration. In particular, the myth of the all-powerful state and old ideological quarrels have been laid to rest. However, the state itself has been slow to reform and has often used international commitments as an excuse for inaction. Most importantly, the gap between elite and public has slowed down modernisation and fuelled fear of the future. More imaginative solutions to public policy and more rigorous policy evaluation are needed.
