In the central-southeastern area of Buenos Aires Province, Argentina, lies a mountainous area of low height in Tandilia that contains important outcrops of quartzite and granite. A large number of buildings are made of massive blocks of rock, some of them with a surface of over 1 ha. In addition to these completely artificial constructions are other structures that are semi-natural, having been made in places with special topographical characteristics and complemented with dry-stone walls. Scanty written documents allow us to attribute some of the constructions to an age before the permanent settlement of the Creole population. In the Tandilia Sierras these structures are commonly known as “corrales de indios” (Indian corrals). This designation involves a double prejudice with regard to function and cultural affiliation. Out of a total of 22 structures, we analyze a group of 4 that were excavated to use to review the written documents.  相似文献

European regional policies in light of recent location theories   总被引:14,自引:0,他引:14  
Despite large regional policy expenditures, regional inequalitiesin Europe have not narrowed substantially over the last twodecades, and by some measures have even widened. Income differencesacross States have fallen, but inequalities between regionswithin each State have risen. European States have developedincreasingly different production structures. European regionshave also become increasingly polarised in terms of their unemploymentrates. This paper describes these trends, and discusses howrecent location theories can help us to explain them and toreconsider the role of regional policies, especially transportinfrastructure improvements, in such an environment.  相似文献

This paper explores the built environment in two rural areas of Northwest Spain that were historically inhabited by two of the so-called “cursed peoples.” Combining contemporary archaeology and material culture studies, we analyze the role played by the house in processes of socio-economic and cultural change, and in the reproduction of internal hegemony within villages. To do so, we study the tensions and connections existing between the transformations undergone by the built environment during the last century and different socio-economic processes, including the depopulation of the rural areas, their conversion into tourist attractions, and the current process of individualisation of subjectivity in line with the transformations taking place in the postmodern era.  相似文献

Over one hundred years of palaeontological research in northwestern Argentina has provided extensive knowledge of Andean lower Palaeozoic fossil assemblages, with trilobites, graptolites, brachiopods and echinoderms being among the most prominent groups. This record is enriched by the recent discovery of soft-bodied worms in Cambrian outcrops of northwestern Argentina. Palaeoscolex sp. cf. P. ratcliffei from the Furongian Lampazar Formation in Jujuy is described, considerably expanding the biogeographical range of this genus and filling the distributional gap, between the well-known early–middle Cambrian occurrences of Palaeoscolex and those of its Ordovician species.  相似文献

We present the results of six years of archaeological work carried out in Heping Dao, Keelung, northern Taiwan. The site has revealed a rich archaeological record spanning a sequence that comprehends most of the history of Taiwan, including the most salient historical landmarks in it. The study of this long-term sequence of habitation in Heping Dao throughout prehistory to current times, allows us to attempt a historical archaeology of the longue duree of the place that in turn enables the establishment of comparisons between periods and raising of specific questions, among them: the general understanding of cultural transformation along the Neolithic and the Iron Age, and in turn the transition Iron Age/Aboriginal historic times in Taiwan, which in our view has to be observed as a history of continuity rather than of interruptions; the recognition of the Chinese presence in Taiwan in the pre-European period; the implantation of the European colony and its effects on the local populations; the differing material remains and impacts caused by the presence of pre-European Chinese and the Qing occupation; and the potential for a comparison between the European and the Japanese colonial projects as seen in the material record.  相似文献

The aim of the present study is to perform a paleodietary and paleonutritional survey on 17 individuals buried in accordance with the prehispanic ritual in the central plateau of the island Tenerife, called Las Cañadas del Teide. We recorded hydrogen, nitrogen and carbon isotope compositions of human bone collagen, bone barium and strontium, and histomorphometrically assessed trabecular bone mass (TBM). Bone trace elements and TBM were compared with reference data derived from a modern sample consisting of 13 individuals. In addition, δ15N and δ13C values were determined in several modern indigenous plants, bone collagen of prehistoric domestic animals (goat and pig), and prehistoric wild animals (a giant lizard, Gallotia goliath and a giant rat, Canaryomis bravoi), which represent food sources potentially consumed by the prehistoric population of the Island. The carbon stable isotope composition of bone collagen ranged between ?20.5 and ?18.6‰ (VPDB), indicating a diet based on C3 plants. Nitrogen isotope values ranged from 8.2 to 12.4‰ (AIR), suggesting a general meat-enriched diet, most likely domestic goats, of higher level consumers. Hydrogen isotope values ranged from ?18 to +4‰, whereas log Ba/Sr was greater than ?0.40 in the vast majority of cases. TBM showed a tendency to osteoporosis in 30% of the individuals analyzed. C-14 dating showed that two burial sites, including 5 individuals, belonged to the post-conquest era (after the 15th century), despite a fully “prehispanic” burial ritual, which lends credenceto the oral tradition that some of the prehispanic population fled to the highlands at the time of the Spanish conquest, and lived there during decades or even centuries. These individuals showed lower δD, δ13C and δ15N, and higher log Ba/Sr values than those buried before the Spanish conquest, suggesting dietary differences between the two groups. Also, women showed a trend to a higher consumption of vegetables than men.  相似文献

Archaeomagnetic dating based on the full geomagnetic field vector was carried out on a limekiln excavated at Pinilla del Valle archaeological site (Madrid, Spain). The limekiln tradition in this area is largely documented by historical sources for recent centuries but the date of the studied kiln's last use was unknown. The combination of mean archaeomagnetic directional and absolute archaeointensity results shows that the kiln was last used between ad 1296 and 1413, in good agreement with two independent radiocarbon dates. This study provides the first archaeomagnetic evidence that the local limekiln tradition dates back to at least late medieval times. Furthermore, the inclusion of these data in the Iberian secular variation curve and geomagnetic field models will help to improve the archaeomagnetic dating technique.  相似文献

THE MAGNITUDE AND CAUSES OF AGGLOMERATION ECONOMIES*   总被引:3,自引:0,他引:3  
ABSTRACT Firms and workers are much more productive in large and dense urban environments. There is substantial evidence of such agglomeration economies based on three approaches. First, on a clustering of production beyond what can be explained by chance or comparative advantage. Second, on spatial patterns in wages and rents. Third, on systematic variations in productivity with the urban environment. However, more needs to be learned about the causes of agglomeration economies. We have good models of agglomeration through sharing and matching, but not a deep enough understanding of learning in cities. Despite recent progress, more work is needed to distinguish empirically between alternative causes.  相似文献

This article analyses the Women's International League for Peace and Freedom's (WILPF) and Women's International Democratic Federation's (WIDF) fact-finding missions sent to Chile in 1974. It explains how women's international organisations presented reports and information about human rights abuses during Genera Augusto Pinochet's dictatorship (1973–1990). By using their publications, oral interviews, memoirs and press reports, the study sheds light on the extensive efforts deployed by the WILPF and WIDF to disseminate knowledge and promote actions designed to improve the lives of Chilean women. The article shows that women's international organisations promoted inclusive ideas of rights, including women's particular experiences under military rule, and that such efforts built in the organisations' previous experiences of human rights activism.  相似文献
