The protocol of preparation of keratinized samples (e.g. hair, furs …) for radiocarbon dating that we have developed is based on the selective extraction of keratin from the bulk part of the shaft (cortex). The aim of this method is to eliminate the cuticle which could contain exogenous carbon from external contaminations. The total treatment takes place as follows: a washing/dry cleaning, a soft treatment with diluted acidic and basic solutions (acid/alkali/acid method) similar to the protocol used for vegetal samples, extraction of keratin by reduction using dithiothreitol and precipitation with sodium deoxycholate and trichloroacetic acid. This method was applied on a hair sample from an Andean mummy, conserved in the collections of the Anthropology Laboratory of the National Museum of Natural History (Musée de l’Homme) in Paris, France. The results of two runs reveal that the mummy is dated to a period between the eleventh century and the first half of the twelfth century. It therefore belongs to the Late Intermediate period (900–1450?ad). The combination of historical research, the study of the body by computed tomography and the analysis of mineral deposits on the surface of the body provides clues to identify the geographical origin of the mummy. These investigations led to determine that the mummy comes from the region of Tarapacá in Chile and belongs to the cultural complex Pica-Tarapacá. 相似文献

The study of the fish bones from the Neolithic shell midden of Suwayh 1, excavated in the 2000s, identified a total of 1060 identifiable fish bones, from 23 families, 33 genera and 28 different species. Radiocarbon dating demonstrates that the sites date to the early 6th to mid 5th millennium BC. The results follow an eight-phase chronology highlighted by an earlier malacological study. The most important taxa were the Carcharhinidae (requiem shark), Rhinopteridae (cownose rays), Sparoidea (Sparidae and Lethrinidae: sea breams and emperors) and Ariidae (sea catfishes). The results of the fish study show that the Suwayh lagoon must have gradually opened up to the sea and been populated with mangroves. The unique presence of so many sharks at this site seems to indicate that the inhabitants had a special interest in shark fishing and that their location was ideal for this specialised activity. Two types of fishing nets and hooks have been discovered, which require the use of different fishing techniques. 相似文献

ABSTRACT This study re‐evaluates the returns to geographic mobility and to the level of education taking into account the interaction between these two variables, and using the distance covered as a proxy for migration costs. We have at our disposal an original French database that permits precise calculation of the distance between the place of education and the location of first employment. For men, we find decreasing returns to spatial mobility as the distance covered rises and increasing returns to mobility with higher levels of education. The marginal returns to spatial mobility for women are lower across the board. 相似文献

During the 1960s, the Yugoslav Socialist authorities gradually recognised Bosnia and Herzegovina's Muslims as a nation. Interestingly, in the 1940s, the Yugoslav Communist leaders refused to consider Muslims even as an ethnic group and saw them only as a religious community whose members had to designate themselves as Serbs or Croats. Why did the regime decide to recognise Muslims as a nation in the 1960s, whereas 20 years earlier they supported the opposite position? To understand the shift, this nation‐building process must be understood as the result of a dual dynamic on the federal and the republican level, where important changes occurred. At the federal one, the Communist authorities initiated a decentralisation process within the context of Yugoslav self‐management in the 1950s, which significantly reinforced the republic elites. This coincided with the resurgence of the national question in the whole of Yugoslavia. Simultaneously, in Bosnia and Herzegovina, a new elite progressively rose to power in the 1960s and put the ‘Muslim question’ on the political agenda. This led to the gradual increase in status of the Muslims from a religious community to an ethnic group at the beginning of the 1960s and then to a nation at the end of the decade. 相似文献

Understanding sailing conditions is a basic requirement for understanding the two periods of settlement of the distant islands of Oceania, initially from the Bismarck Islands off New Guinea as far as Samoa and later from Samoa throughout East Polynesia. The question of a “navigational threshold” between these two worlds is the focus of this paper. A computer simulation is presented that quantifies the difficulty of sailing virtual canoes in the differing wind conditions in both areas. The model demonstrates substantial differences in ease of voyaging up to and beyond Samoa. That this measure is so markedly different between these two worlds gives support for the hypothesised pause between the discovery and settlement of islands West and East of Samoa. 相似文献

Starting from questions about the nature of cultural diversity, this paper examines the pace and tempo of change and the relative importance of continuity and discontinuity. To unravel the cultural project of the past, we apply chronological modelling of radiocarbon dates within a Bayesian statistical framework, to interrogate the Neolithic cultural sequence in Lower Alsace, in the upper Rhine valley, in broad terms from the later sixth to the end of the fifth millennium cal BC. Detailed formal estimates are provided for the long succession of cultural groups, from the early Neolithic Linear Pottery culture (LBK) to the Bischheim Occidental du Rhin Supérieur (BORS) groups at the end of the Middle Neolithic, using seriation and typology of pottery as the starting point in modelling. The rate of ceramic change, as well as frequent shifts in the nature, location and density of settlements, are documented in detail, down to lifetime and generational timescales. This reveals a Neolithic world in Lower Alsace busy with comings and goings, tinkerings and adjustments, and relocations and realignments. A significant hiatus is identified between the end of the LBK and the start of the Hinkelstein group, in the early part of the fifth millennium cal BC. On the basis of modelling of existing dates for other parts of the Rhineland, this appears to be a wider phenomenon, and possible explanations are discussed; full reoccupation of the landscape is only seen in the Grossgartach phase. Radical shifts are also proposed at the end of the Middle Neolithic. 相似文献

Previous environmental equity studies have examined the spatial distribution of aircraft noise across cities. Their findings show that, in several cities, visible minorities and low-income populations are most affected by aircraft noise. In contrast, one study concludes that well-off populations are the most affected. These contradictory findings support the use of a comparative approach for several cities. The aim of this study is twofold. First, we want to identify if there are groups in the population that are in a situation of inequity to aircraft noise exposure in Toronto, Montréal, Vancouver, and Calgary. Then, we want to check if the exposure to the aircraft noise of the different groups varies significantly from one metropolis to another. We use the recommended noise exposure contour maps in Canada: the Noise Exposure Forecasts. Next, four variables are extracted from the 2016 Statistics Canada census at a fine-scale level (dissemination areas): that is, the percentages of low-income, visible minorities, 0- to 15-year-old, and 65-year-old and over populations. The results of a mixed effects logistic regression model show that environmental inequities in terms of exposure to aircraft noise for the four population groups are not consistent from city to city. 相似文献

This article explores the relation between gender identities and spatial aspects of audience reception by means of a case study on film-viewing in the Turkish and Moroccan diasporic communities in the Belgian city of Antwerp. Drawing on feminist and gender approaches to audience reception on the one hand, and research into the spatial dynamics underlying audience reception on the other, we look at film-viewing as a socially and spatially meaningful practice that is relevant for the understanding of gender identities in diasporic families. This article is based on the results of a four-year project on diasporic film cultures in Antwerp that investigated how film-viewing practices relate to social and cultural dynamics within the Turkish and Moroccan communities. The data that are discussed include participant observations, in-depth interviews and group interviews with a varied sample of people with Turkish and Moroccan backgrounds. The results show that although film-viewing, especially in the public space of the film theatre, can be mobilized by women as an emancipating social practice, gendered power structures often prevail. Also in the domestic contexts, a more traditional gender division is articulated by the respondent concerning family viewing. We conclude that the space of the film theatre and film-going serve the continuity and stability of gendered family relations, rather than subverting them. 相似文献
