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

The Myntling Register contains some little known and, in some respects, highly unusual demographic evidence relating to the period from around the later fourteenth century up to the 1970s and to the wealthy Lincolnshire Priory of Spalding. It is in the form of hundreds of ‘family trees’ relating to the villein families of the priory's major manors. It has evidence of interest to economic historians of medieval England on several fronts, the three of which dealt with here are proportions of males to females, percentages of females marrying, and most particularly numbers of surviving children per family. This evidence, whilst by no means perfect, is of a much more direct kind than that often used in attempts to calculate later medieval population. As such it has a contribution to make to the very vexed question of later medieval demography.  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

The interrelationships between macro and micro factors in the analysis of interstate migration in the United States are explored. A synthesis between these factors is attempted "by combining objectively calibrated characteristics of states with their subjectively measured counterparts....First, the relationships between the objective variables and their subjective counterparts are analyzed. Second, both sets of variables are used to explain residential preferences and migration. Third, a series of path models are constructed to indicate how the subjective variables act as intervening variables between their objective counterparts and migration."  相似文献
