The relationship between agriculture, sedentarization and the emergence of inequality has been a common subject when analysing the transition between egalitarian and non‐egalitarian societies. However, the strategies used during that process and their archaeological expressions are difficult to detect and interpret. The aim of this paper is to provide an example – the emergence of Early Iron Age cremation cemeteries in the Middle Tagus valley – of how this transformation could have been materially expressed. Through the study of Arroyo Culebro D and other cremation cemeteries, we will analyse the crucial moment when the structural changes that sedentarization carries started to be ideologically assumed, expressed and (or) repressed.  相似文献

This paper explores the potential of acoustics to interpret the prehistoric rock art of southern Andalusia (Spain). Tests undertaken in two areas, north of the Celemín river and the Bacinete area, will form the basis of our discussion. The results obtained at a selection of rock art sites show that the two key rock art sites, El Tajo de las Figuras and the large shelter at Bacinete, both with the majority of paintings in the earlier Laguna de la Janda style, had good resonance values. In contrast, at most of the other minor sites tested, the values for resonance were negative or insignificant, regardless of whether they were painted in Laguna de la Janda or schematic style. We conclude that the major rock art sites in southern Andalusia were chosen not only for their geological appearance and location in the landscape, but also for their acoustic properties.  相似文献

Study of the Iberian Copper Age has experienced a remarkable upheaval in the last two decades. The discovery in central and southwestern Iberia of a significant number of ditched enclosures, a site type almost unknown in this region until the mid 1990s, has opened up new lines of research. Particularly interesting is the existence of some exceptionally large sites. Largest of all is Valencina de la Concepción (Seville, Spain), covering an area of 450 ha and featuring several outstanding megalithic monuments, thousands of pits and material assemblages revealing middle and long distance contacts. In this paper we discuss the implications of the Valencina mega-site for the study of settlement variability, monumentality and population aggregation as key phenomena in the rise in social complexity in Copper Age Iberia.  相似文献

This article examines the role assigned to culture in general and to cultural industries and diversity in particular by the Canada-EU Comprehensive Economic Trade Agreement (CETA). Although it pursues further economic liberalization, the arrangement is about much more than trade: its preamble, for instance, contains a reference to the 2005 UNESCO Convention on the Diversity of Cultural Expressions. Nevertheless, the text lacks a general exception clause protecting culture. This paper examines the consolidated CETA text from the perspective of political economy to clarify to what extent this is an opportunity to reconcile rules of free trade with cultural policies aiming to protect and promote the diversity of cultural expressions, especially when the latter derive from cultural industries in both analogue and digital scenarios.  相似文献

This study examines the association between corporate social performance (CSP) practices and membership in Business for Social Responsibility (BSR) between 1992 and 2006. BSR is a business association that seeks to help its members adopt enhanced CSP practices. While there is an emerging literature examining voluntary initiatives as alternative policy mechanisms to regulations, most research is focused on initiatives that emphasize environmental protection. Further, studies suggest that membership in strictly voluntary initiatives tends to be associated with lower environmental performance because of “free‐riding” behavior by participants. BSR differs along two dimensions when compared with other voluntary initiatives examined in the literature. First, it is a comprehensive voluntary social initiative that helps firms from diverse industries address multiple CSP issues simultaneously. Second, it might limit opportunism by not offering blanket certification to its participants. Our results indicate that BSR members exhibit greater levels of positive social impacts without demonstrating significantly different levels of negative social impacts. This suggests that participation in voluntary initiatives that avoid granting blanket certifications may be associated with the adoption of new corporate social responsibility practices but not linked to the shedding of entrenched routines that produce negative externalities.  相似文献

The pre-Magdalenian phase of the Côa River Valley open-air rock art is mostly distributed at the boundary between the rocky valley slopes and the floodplain that correspond to the most favourable geomorphological setting for the preservation of pecked and deeply superposed engravings of the most famous artistic phase of the area. The natural vertical panels of the engraved art located at this geomorphological interface have suffered weathering during two cold events of the Lateglacial. They were buried by several colluvial and alluvial deposits. The reconstruction of the sedimentary and archaeological context of the CôaRiver Valley engraving permits a better assessment of the preservation processes and interpretation of Palaeolithic open-air rock art.  相似文献

Is Greener Whiter Yet? The Sustainable Slopes Program after Five Years   总被引:2,自引:0,他引:2  
This study focuses on two basic questions: Are voluntary programs effective in promoting higher environmental performance by participant firms? If so, which distinct areas of environmental performance are more likely to be improved by firms joining a voluntary environmental program? We address these questions by assessing the environmental effectiveness of the ski industry’s Sustainable Slopes Program in the western United States between 2001 and 2005. We found no evidence in our five-year analysis to conclude that ski areas adopting the SSP displayed superior performance levels than nonparticipants for the following areas of environmental protection: overall environmental performance, expansion management, pollution management, and wildlife and habitat management. SSP participants only appear to show a statistically significant correlation with higher natural resource conservation performance rates. For policymakers, these results suggest that caution is needed before a priori assuming that strictly voluntary programs can be effective in promoting comprehensive superior environmental performance.  相似文献

Extant research has analysed the impact of security policies, truces and informal agreements on both the dynamics and traits of organized violence in El Salvador. However, less is understood about variation in the levels of lethal violence across subnational units. This article contributes to filling this gap. Based on a case study of the municipality of Chalatenango, the analysis shows that community organization and translocal dynamics are crucial to explaining violence containment. Local communities have managed to control the levels of lethal violence and deter criminal actors amid a national context characterized by state neglect and chronic violence. Community organization is not territorially bound but extends across transnational networks. Migrants are a source of livelihoods for the local population; they also contribute to providing public goods and participate in local forms of organization. Transnational networks have forged a migration corridor that enables immigration to the United States. In addition, community organization informally contributes to the capacity of the local state to perform its functions, thereby shaping cooperative state–society relations. This analysis sheds new light on the conditions shaping the variation in levels of violence at the subnational level and local governance dynamics.  相似文献
