A very accurate archaeological dating of a Roman site in NE Spain (El Vila-sec) was made based on the typology of pottery artifacts. Three different phases were identified with activity ranging from the mid-1st century BC to the early-3rd century AD. Analyses of bricks from kilns at El Vila-sec produced data on their stored archaeomagnetic vector. These data were compared with the secular variation curve for the Iberian Peninsula and the SCHA.DIF.3K regional archaeomagnetic model. Both, the reference curve and the model, produced probability distributions for the final period of use for two kilns from the second archaeological phase that were not used during the third phase. At a 95% confidence level, both time distributions cover a wide chronological range including the presumed archaeological age. Both the Iberian secular variation curve and the SCHA.DIF.3K regional model proved to be suitable models for dating the site, although on their own they do not produce a single unambiguous solution. This archaeomagnetic approach could also be applied to neighbouring archaeological sites that have an imprecise archaeological age. 相似文献

The Eagle Owl (Bubo bubo) is an important leporid remains accumulator at archaeological sites. Taphonomical studies of modern leporid remains from nest assemblages of this nocturnal raptor aim to establish the main characteristics that define the taphonomic signature of Eagle Owls in order to distinguish them from that of other leporid predators, namely diurnal raptors, terrestrial carnivores and humans. However, analyses carried out so far have shown that the identification of diagnostic features of Eagle Owls leporid nest accumulations is not a straightforward issue – variability has been observed. Age and size of prey are pointed among others as accountable factors but little research has been done on the study of these variables. Here we present the analysis of two samples of modern leporid remains recovered from Eagle Owls nests with the aim of contributing new data to this subject. The high presence of juvenile individuals in both samples enables us to assess anatomical representation, breakage and digestion patterns of immature leporid remains and also to compare them with other assemblages richer in adult prey. Results show that the main characteristic features noted in previous works which recognise Eagle Owls as agents of leporid bones accumulations in the fossil record, are not significantly affected by the age of prey. Less variability than originally thought occurs which means other variables need to be further investigated. 相似文献

The history presented by the Ömie in the pre-Independence research appears fundamentally different from the history presented by the Ömie in more recent research. The basis for considering these two renditions as analytically equivalent is examined. It is proposed that the justification lies not so much in the content of the two representations as in the negotiations of the terms of the ethnographic encounter which elicited them. It is proposed that these renditions of history are actually the terms of the relationship between the researcher and the informants negotiated in the course of their interaction on two separate occasions. 相似文献

This article contributes to conceptual debates on gender transformations in the context of migration and transnationalism. We do so by discussing developments in gender relations and identities among Polish post-accession migrants in Norway; analysing the intersections of continuities and changes, relationally, as these are produced spatially and temporally. We draw on ethnographic data collected among Polish migrants in the Norwegian cities Oslo and Bergen (2009–2012). Our focus on continuity and change in gender relations and identities, in the context of migration and transnationalism, stems from a realization that migration often leads to assumptions of either radical change, or conservative continuity. Meanwhile through an analytical lens sensitive to relationality and socio-spatial circumstances, we find friction, disagreement, as well as negotiation and resolution, and we argue for the variety of ways in which continuity and change may run parallel, reflective of variations in transnational habitus produced in relation to social class. We pay attention to locations and scales, as salient for how gender relations and identities are reproduced, transformed or contested. The flexible continuum we find reveals diverse strategies of coping with migratory situations, as well as complex interplay between migrants’ agency, existing structures and engendered understandings. 相似文献

Bioarchaeological analyses of teeth rely traditionally on noninvasive methods that reveal essential information about past individuals and populations. Methodological developments have revolutionized the discipline, but their application is commonly invasive and destructive. The resulting loss of material and information can be buffered through 3D technology applications. Although useful, it is essential that we carefully assess the reliability of these methods, in order to understand what data are preserved and which ones are lost through their application. This study offers a protocol for the implementation of 3D technology in the fabrication of ancient teeth analogs. Analog accuracy was assessed by comparing metric and non-metric traits between the originals and their respective analogs. Results showed that metric traits preserved well, but the preservation of non-metric traits was partially hindered. 相似文献

The use of seashells for the decoration of pottery from the sixth millennium cal BC is well known in the western Mediterranean, with the emergence of so-called Cardial Pottery. Actually, the most discussed issue up until now has been the use of bivalves for impressed decoration. However, the experimental approach followed in the present study provides for the first time clear evidence for the utilization of a very specific group of shells as tools for the decoration of some of the early pottery productions in northwest Africa. In particular, we propose the use of cowry, a gastropod family with a well-known ideological and symbolic role in many human cultures around the world. Also, it is suggested that cowry was used for making impressed wares on the opposite European shore. The implications for reconstruction of Neolithic diffusion along both the European and African coasts of the Mediterranean are of great significance. 相似文献

Fuelling Social Inclusion? Neo‐extractivism,State–Society Relations and Biofuel Policies in Latin America's Southern Cone 下载免费PDF全文
Scholarship on neo‐extractivism agrees that this ‘post‐neoliberal’ model of development is founded on an inherent contradiction between the commitment to continue natural resource extraction and the need to legitimize these activities by using their revenues for poverty reduction. Using the cases of the national biofuel policies of the ‘post‐neoliberal’ governments of Argentina, Brazil and Uruguay, this article enquires why and how these policies emerged, how they were implemented, and how the resulting national experiences exemplify the inherent contradictions embedded in neo‐extractivist policies. Adopting a strategic‐relational approach to analyse state–society interaction, it is argued that the scope of progressive policies is conditioned to a large extent by pre‐existing social structures, institutions and state–society interactions. The article shows how progressive reforms intersect with the prevailing interests of agribusiness and state actors and are recast and used for different ends as these interact with powerful actors such as the multinational soybean complex and agrarian movements. It is suggested that the prevailing over‐emphasis in the neo‐extractivist literature on the politics of domination and contestation overlooks the multiple and complex rural responses of the different progressive governments. It also obscures the possibilities to explore the ruptures and continuities of these countries’ governments with previous models, and therefore fails to recognize state advances. 相似文献

This paper discusses the out of school routines of a group of ‘literature-devoted’ children of the city of Madrid (Spain). The children and families were recruited for the study at a library, a children's bookstore and a puppet show in a park. Participants provided information on their weekly routines through several procedures: surveys, photographs of their daily lives, interviews based on the photographs and interviews with parents. We develop a spatially based model that allows us to identify four styles of activity in children's out of school lives: homebound children, non-scheduled children, outdoor and scheduled children, and fully scheduled children. Our results suggest that there is significant diversity in the ways in which children's after-school time is organized, even within a middle-class and socially homogeneous sample as the one in this study. Also, the range of activities our participants engage in seems to contradict current portraits of Western urban children's lives as constrained. 相似文献
