The Magdalenian culture-stratigraphic unit in Western Europe, despite being a construct of nineteenth-century prehistoric archeologists, does have reality as a continuous network of human inter-relationships, whose ecologically transcendent range expanded through the course of the Late Last Glacial, in many ways reminiscent of Braudel’s histoire de la longue durée—in this case lasting some 9,000 calendar years. At the scale of the moyenne durée, the Magdalenian underwent several reorganizations [represented by its Initial, Lower, Middle, Upper, Final, and Epi-Magdalenian (i.e., Azilian, Federmesser) stages]—with distinctly regional manifestations and inter-regional connections—that in part can be understood in light of environmental/resource changes and variations at the scales of millennia and natural regions. At the scale of the courte durée, we are dealing with the adaptations of local and regional hunter-gatherer bands and the peculiarities and vicissitudes of their circumstances measured by forager group territories and centuries. Numerous, diverse concrete archaeological manifestations of territories and inter-group contacts support the growing consensus about the social reality of the Magdalenian phenomenon and the changes and variations that characterized it within a range that ultimately stretched from Portugal to Poland during the last millennia of the Pleistocene. Here, the focus is on Cantabrian Spain as one of the core or source areas of the Magdalenian cultural tradition that arose out of the Solutrean experience some 20,000 calendar years ago (about a millennium later than in France) and that was intimately linked to the process of human recolonization of upland and northerly regions of western and ultimately central Europe during the course of Greenland Stadial 2 and early Greenland Interstadial 1. Finally, archaeological and paleobiological indicators clearly point to major breaks in human adaptations and ways of understanding the human place in the universe a few centuries after the onset of Holocene conditions in Vasco-Cantabria, i.e., the development of Mesolithic cultures about 11,000 calendar years ago.  相似文献

Disease is a more efficient killer of armies than man, but military historians tend not to dwell on this fact, for fear of relegating human volition to a secondary role in the outcome of wars. Thus, studies of the Cuban War of Independence from 1895 to 1898 tell of thrilling machete charges and awe-inspiring battleships, but pay insufficient attention to the insects and microbes that really killed the Spanish army and prepared the ground for the liberation of Cuba. This essay argues that the mosquito and yellow fever did most of the work of freeing Cuba from Spanish military occupation. It also tells how the theory of a Cuban physician, Carlos Finlay, helped to liberate the island from yellow fever following the American occupation in 1898. In this way the essay unites two sundered histories that belong together, and then goes on to explain why the medical community ignored Finlay for almost 20 years, just time enough to allow Cubans to found a new nation.  相似文献

Abstract. This paper deals with the impact of migration on wages. We introduce a spatial dimension into the job search framework, so that the agent faces neither the same job offer distribution nor the same search costs when looking for a job inside his local labor market. This is in comparison to the agent searching outside his local labor market, where migration costs are a factor. We estimate wage equations in which we introduce the decision to migrate as a binary choice, and later as a polychotomic choice (stayer/mover from provinces to Paris/mover from provinces to provinces). We find no selection effect for people with low levels of education, and a positive selection effect for highly educated migrants. When we distinguish the migration destination for highly educated from provinces, we find a hierarchical effect, that is, the selection effect is higher for men who migrate to Paris than for those who migrate to other provinces.  相似文献
