Diverse hunter-gatherer groups inhabited Tierra del Fuego (Argentina) from the end of the last glaciation until recent dates. Sadly, the contact with European settlers was fatal for them, and a series of different causes led to their disappearance. Among these groups, Selknam inhabited the central and northern part of the Isla Grande (Tierra del Fuego) until the first decades of twentieth century. Although many travellers and ethnographers described this society, the recorded information related to vegetal resources management and plant exploitation strategies was quite scarce. As a consequence, a picture was created in which plants, and especially plant food, had a very poor role in the everyday life of these people. In this work, we present the results of the first archaeobotanical analyses carried out on an excavated site related to the Selknam hunter-gatherers. The information presented here, along with future studies, will enlarge the knowledge and enrich the image that we have of Selknam’s plant use, economy and social relations. 相似文献

In this article, we discuss children's becoming as food consumers in the intersection of various foodscapes. We draw from a project, Children as co-researchers of foodscapes, where we have been working with children as co-researchers, using basically ethnographic methods, and as co-designers in a collaborative design effort. This article focuses on the findings from a theoretically inspired perspective, using the concept of foodscapes. These are food-related structures of different kinds, which evolve as the child explores them and where children as food consumers are generated. In this article, we highlight the scapes of taste, routines, people, things, commerce, child (as opposed to adult) and health and give brief accounts of the way the children related to them. Finally, we turn to the benefits of working with foodscapes for a better understanding of children's becoming as food consumers in the intersection of various foodscapes. This article is based on data gathered by the children, but also on our fieldwork notes and observations following the children in their foodscapes. 相似文献

Abstract Multiple sclerosis (MS) was first presented in a clinical setting in 1838. In this paper the presentation and treatment of a transient hemiparesis in a drummer in 1789 is discussed. This may have been an early case of MS and presents evidence against the theory that MS is an infectious disease beginning in the 19th century. 相似文献

This study analyses British and local Iraqi elites’ efforts to avoid social revolution through promotion of economic development during the last years of the Iraqi monarchy. Discussing the complex set-up of domestic Iraqi elites and their ambiguous relations with British officials in Iraq, it argues that the structural composition of the Iraqi state itself is an important explanatory factor for the swift overthrow of the old regime in 1958. Using British archival records, this article analyses the politics of avoiding reform and promoting economic development to which Iraqi elites and the British were privy. It shows how economistic ideas of ‘modernisation’ and economic growth were believed to be the solution to Iraq's endemic problems of social unrest and politicisation of large parts of the population. Arguing that increased wealth through oil-fuelled development programmes would ultimately trickle down to all strata of the population and thus stave off the danger of revolution, the British failed to realise that Iraq's structural setup with its unscrupulous politicians and wealthy landowners at the apex of power, along with an all-permeating patronage system, effectively hampered any dispersal of what little new wealth was generated through these projects. 相似文献

Forensic Anthropology and Bioarchaeology studies depend critically on the accuracy and reliability of age-estimation techniques. In this study we have evaluated two age-estimation methods for adults based on the pubic symphysis (Suchey–Brooks) and the auricular surface (Buckberry–Chamberlain) in a current sample of 139 individuals (67 women and 72 men) from Madrid in order to verify the accuracy of both methods applied to a sample of innominate bones from the central Iberian Peninsula. Based on the overall results of this study, the Buckberry–Chamberlain method seems to be the method that provides better estimates in terms of accuracy (percentage of hits) and absolute difference to the chronological age taking into account the total sample. The percentage of hits and mean absolute difference of the Buckberry–Chamberlain and Suchey–Brooks methods are 97.3% and 11.24 years, and 85.7% and 14.38 years, respectively. However, this apparently greater applicability of the Buckberry–Chamberlain method is mainly due to the broad age ranges provided. Results indicated that Suchey–Brooks method is more appropriate for populations with a majority of young individuals, whereas Buckberry–Chamberlain method is recommended for populations with a higher percentage of individuals in the range 60–70 years. These different age estimation methodologies significantly influence the resulting demographic profile, consequently affecting the biological characteristics reconstruction of the samples in which they are applied. 相似文献

Changes in resource use over time can provide insight into technological choice and the extent of long-term stability in cultural practices. In this paper we re-evaluate the evidence for a marked demographic shift at the inception of the Early Iron Age at Troy by applying a robust macroscale analysis of changing ceramic resource use over the Late Bronze and Iron Age. We use a combination of new and legacy analytical datasets (NAA and XRF), from excavated ceramics, to evaluate the potential compositional range of local resources (based on comparisons with sediments from within a 10 km site radius). Results show a clear distinction between sediment-defined local and non-local ceramic compositional groups. Two discrete local ceramic resources have been previously identified and we confirm a third local resource for a major class of EIA handmade wares and cooking pots. This third source appears to derive from a residual resource on the Troy peninsula (rather than adjacent alluvial valleys). The presence of a group of large and heavy pithoi among the non-local groups raises questions about their regional or maritime origin. 相似文献

New bird fossils from the Santa Cruz Formation (lower–middle Miocene), Santa Cruz Province, Patagonia, Argentina, are described. They represent an indeterminate species of the extinct anhingid Macranhinga and a new genus and species of basal Anatidae Ankonetta larriestrai. The record of the giant darter Macranhinga constitutes the southernmost record for the family, and expands the known stratigraphic range of the genus, previously restricted to the upper Miocene. Based on an analysis of the fossil anhingid record from South America, we hypothesize that giant darters disappeared from South America in the early Pliocene due to climatic deterioration, regression of marine and freshwater environments, the arrival of placental carnivorous mammals, and also probably by competition with phalacrocoracid cormorants. The new anatid Ankonetta is based on an incomplete but informative tarsometatarsus, with superficial similarities to extant Dendrocygna. A brief overview of several fossil ducks from the Patagonian Cenozoic concludes that most pre-Pliocene examples belong to non-anatine taxa, indicating that plesiomorphic ducks were the dominant anseriforms in those times, a pattern also evident on other continents. 相似文献

This article argues against the dominant Anglophone and Francophone interpretation of Fichte, which reads him as advancing either a form of ethnic or cultural nationalism. It claims that what is missing from the current reception of Fichte is the essentially philosophical and cosmopolitan character of his nationalism – the fact that the Addresses to the German Nation uses non‐empirical and cosmopolitical concepts to develop and articulate its nationalistic viewpoint. It therefore claims that the notion of a national philosophical idiom that the Addresses present, far from being a screen for its nationalism, is its driving engine. It does this by considering the problems of translating the German locution ist unsers Geschlechts. Consequently, it is claimed that the cosmo‐nationalism of Fichte is not reducible to a set of claims regarding ethnicity or even the empirical world, even if a discourse on the organismic, on what counts as life, irreducibly haunts the Addresses. 相似文献
