Eastern North America in late Pleistocene times was characterized by two major environmental regions: a periglacial tundra or open spruce parkland and an extensive complex boreal/deciduous forest in the unglaciated, lower latitudes. These environments selected for different adaptive strategies on the part of human foraging groups—known archaeologically as Paleoindians. Those in the tundra and tundra-forest region were highly mobile, possibly specialized hunters, exploiting caribou; those in the forest were generalists, exploiting a variety of subsistence resources with a less mobile settlement system. There is little evidence in either area for hunting of Pleistocene megafauna. These differences in adaptive strategies are reflected in the record of sites and isolated fluted points scattered throughout the region, as well as aspects of tool technology, function, and patterns of stone use.  相似文献

Numerous scholars have outlined what they believed to be the consequences of the advent of iron technology in sub-Saharan Africa: increased food production using more efficient bush clearing tools; increased population densities; larger and more stable communities; increased trade, specialization and social differentiation; and the embryonic rise of modern politics. (Davidson 1974.) However, little has been demonstrated in the field.A regional study of the Bassar iron industry of northern Togo has shown that the rise of large-scale iron production may lead to higher population densities, larger and more stable communities, a more aggregated settlement pattern in the ore zone, and increased craft specialization and trade. However, it does not necessarily result in a significant increase in the degree of political centralization. The Bassar data also suggest that even the appearance of relatively small scale iron production may generate similar trends, albeit at more modest levels.
Résumé De nombreux auteurs ont décrit ce qu'ils proposent d'avoir été les conséquences de l'adoption de la technologie de fer dans l'Afrique au sud du Sahara: augmentation de la production de nourriture à l'aide des outils plus efficaces pour débroussailler le paysage; augmentation des densités de population; communautés plus grandes et plus stables; croissance de la commerce, de la specialisation artisanale et de la differentiation sociale; et naissance embryonique de la politique moderne (Davidson 1974). Cependant il n 'y a que très peu de ce schéma qui a été validé par les recherches sur le terrain.Une étude régionale de l'industrie du fer des Bassar du nord de Togo a montré que l'essor de la production de fer à grande échelle peut aboutir à des densités de population plus hauts, des communautés plus grands et plus stables, une répartition de l'habitat plus agrégée dans la zone des minerais de fer, et l'augmentation de la specialisation artisanale et du commerce. Cependant il n'aboutit pas obligatoirement à une centralisation importante au niveau politique. Les résultats fournis par cette étude des Bassar nous amènt à proposer aussi que même l'apparition de la production modeste de fer peut donner naissance à des développements comparables, mais d'un ampleur plus restreint.

Résumé Isenya est le premier site acheuléen fouillé sur les hauts plateaux du Kenya. Sa richesse en vestiges lithiques et fauniques en fait dès maintenant un gisement important pour la connaissance des hominidés du Pléistocène moyen. Isenya est inclus dans un contexte sédimentaire fluviatile, indiquant que les hommes préhistoriques se sont installés sur une barre sableuse, le long d'une rivière qui était alors peut-être pérenne. La convergence des informations géologiques et archéologiques permet d'expliquer la mise en place des vestiges, la positionin situ de plusieurs niveaux d'occupation superposés, le faible degré de perturbation qu'ils ont subi, et l'origine essentiellement anthropique des associations os/pierres. L'industrie lithique est caractérisée par une grande abondance de bifaces et de hachereaux dont les proportions varient dans le temps. Une première analyse de l'ensemble apporte d'ores et déjà des indications sur les comportements techniques: les chaînes opératoires sont décryptées, depuis l'acquisition des matériaux jusqu'à l'obtention des outils. La faune associée à cet outillage est dominée par des animaux de savane ouverte (Alcelaphini etAntilopini). Son étude détaillée mettra en évidence les stratégies d'acquisition du gibier et son mode de consommation. Attirés, entre autres raisons, par la proximité de l'eau et des affleurements de phonolite, source principale de matière première pour l'outillage, les hominidés ont occupé cet enfroit de façon répétée dans un court laps de temps, selon une périodicité à rapprocher sans doute des comportements de subsistance.
Isenya is the first Acheulian site excavated in the Eastern Highlands of Kenya. Very rich lithic and faunal remains in a fluviatile sedimentary context indicate hominid activity on a sandy bar next to a river, which was perhaps perennial. Microstratigraphy and archaeological data permit reconstruction of the processes by which the remains were deposited. Severalin situ occupation layers show only a slight degree of perturbation. The bone assemblage is of anthropic origin, and the lithic industry is characterized by an abundance of bifacial pieces, level VI being particularly rich in cleavers. From the analysis of the lithic industry we can obtain some idea of hominid technological behaviour, most notably the operational chains of tool production from the procurement of raw materials to the knapping sequences. The fauna associated with the lithic materials is dominated by animals of the open savanna (Alcelaphini andAntilopini); and its detailed study will allow us to specify the strategies used in the procurement of game and its subsequent consumption. Without doubt, the reasons for hominid occupation at this particular site will be impossible to explain fully. However, choice of this location, where evidence for several different activities has been uncovered, should be considered in terms of the proximity both of water and of outcrops of phonolite, the principal raw material for tool-making. Repeated occupation by hominids over a short time may, perhaps, correspond to the periodicity of their subsistence behaviour.

ABSTRACT. The dynamic relationship between sectoral value added and regional economic growth is analyzed using a stochastic intersectoral model estimated by ordinary least squares and linear systems techniques. A state-space portion of the model identifies the time element of sedoral value added. Dynamic multipliers, tracing the temporal path of regional growth, are calculated for the state of Georgia over the period 1963–1986. This application shows that the impacts of sectoral shocks can follow cyclical as well as monotonic patterns and that the direction and magnitude of the impact may change over time.  相似文献
