An investigation of three Andean towns in their regional setting forms the basis for an assessment of urban-rural demographic differences. The towns are found to have been ethnically distinct, with a larger proportion of whites than the mainly Indian rural areas. The urban populations also had a larger surplus of women, lower average marriage ages for women but lower proportions married, a higher illegitimacy rate and a slightly older age structure. Trends in urban districts differed from those in rural areas. The towns suffered major population losses, and their share of the regional population fell from nearly 10% in 1778 to around 5% in 1841. The factors affecting population trends are examined in order to identify those which had a differential urban-rural impact. Earthquake and warfare were of key significance. In a regional context of economic depression and population stagnation, these two catastrophes instigated a major urban recession. The three towns shared in the urban decline experienced in many parts of Latin America, but their recession was particularly pronounced owing to the impact of catastrophes.  相似文献

In this paper we analyse a text in Gooniyandi (southern Kimberley, Western Australia), a myth about the acquisition of fire. Our analysis, broadly structuralist-functionalist in orientation, uses a number of complementary modes of myth analysis, including a variety of structuralism which draws on Lévi-Strauss. Our main point, however, differs from his concerns. It is that the analysis of a myth (indeed, of any text) cannot be pursued independently of its language, and of the linguistic choices implemented by the narrator. Relevant choices include not just lexical, but also grammatical ones, selections of grammatical construction (and patterns in them), not, of course, in the language of translation (English), but in the language of the text. We suggest that our method should be generally applicable to myths in any language.  相似文献

In 1985 a Neanderthal skeleton was found in the cave of Kebara in southern Mt. Carmel. Electron spin resonance (ESR) dates have been obtained on tooth enamel of gazelles found in layer X, just overlying the layer in which the skeleton was found. Assuming early uptake of uranium by the teeth, they yield an age of 60 ± 6 ka; assuming gradual, linear uptake of uranium yields an age of 64 ± 6 ka. Both age estimates are consistent with a previous estimate for the skeleton, based on TL dating of burnt flint, of 60 ± 4 ka.  相似文献
