If the overall expansion of the farming system was determined by the Neolithic Demographic Transition (NDT), i.e. by demographic pressure, what determined the rate of expansion? What is the link between the rate of expansion, the farming system and demographic density? In a first approach, the issue of the different rates of expansion of the farming system on the map is addressed in terms of 21 geo-ecological, climatic and cultural factors and forager populations, via an ordinary least square regression technique (OLS). In a second approach, the variability of the rate of expansion is analyzed in terms of specific patterns identified for the ceramic culture areas, via a cluster analysis. The expansion rate is negatively correlated with the intensification of the agricultural system, as well as with demographic density. Expansion is slow in ecosystems with an intensive farming system with relatively high demographic density, and vice-versa. 相似文献

This article explores the paths through which percentage imposed itself in the political sciences. At first used in the financial domain, percentage is incorporated in 1662 by Graunt in the field of studies of mortality; in the beginning of the 19th century it migrates towards studies in population growth, then it migrates to other territories to become a tool of general application. Each migration enters the framework of a new problematic: “the birth of mortality” in one case; “the birth of population” in the other. The recourse to percentages thus appears as one of the elements in the foundation of statistical objectivism. 相似文献

L'auteur montre que contrairement aux études dans ce domaine la dureté totale de l'eau potable ne semble pas influencer la mortalité ischémique du cœeur. Cette relation est examinée selon que la localisation géographique des municipalités des Cantons de l'Est ob-servées se trouve sur un gîte calcaire, selon l'origine de I'approvisionnement en eau potable. Les résultats montrent que les composantes physico-chimiques telles que le calcium et le magnésium peuvent dans des cas précis étre déterminants. L'emploi de données socio-économiques (l'âge du logement, le revenu, par exemple) apparaît plus probant.
Contrary to the results of other studies, the total hardness of drinking water does not seem to influence the death rate from ischaemic heart trouble in the Eastern Townships. This conclusion is based on an analysis of mortality rates in relation to the origin of domestic water supplies and location on sources of calcium. Although the results show that the physico-chemical components, such as calcium or magnesium, can be determined in certain cases, socio-economic variables, such as housing age or income, seem more significant. 相似文献

Lacan was interested by the treatment of the probabilities, the theory of games and decision, all topics that gave way to an interpretation of Pascal’s calculus of partition and of the famous argument of betting. Starting from a critical examination of Kant’s transcendental aesthetics, that Lacan propounds to the philosophers to replace by logical space and time of the theory of game (as a substitute), the psychoanalyst attempts to prove that Pascal is probably the forefather of the theory of game and decision. A number of interpretations of the «geometer of hazard», which will happen in the years 1970, are in debt, perhaps unconsciously, surely in a secrete way, to the farther lacanian interpretation. 相似文献

Study of an ostracode assemblage from the Miocene Fyansford Formation near Mornington allows determination of the principal characteristics of the hydrologic environment at that time. Palaeodepth was upper epibathyal (about 150–250 m). The oxygen minimum zone mostly was weakly demarcated at about O2 5 ml/l. Productivity was good and the benthic ostracode microfauna was rich and varied. Occasionally, a sudden and strong increase in productivity occurred which correlated to a rapid and well marked increase in the oxygen minimum zone. Physico-chemical factors, which developed following bacterial breakdown of organic matter that had accumulated on the bottom, are reflected in Bradleya shells by distinct signs of aggradation/degradation. A few allochthonous forms from the nearby continental shelf were transported downwards onto this part of the upper slope. Bottom currents contributed (by furrowing) to the formation of calcareous ‘hard grounds’. Bradleya morningtonensis n.sp. is described as new. 相似文献
