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

The development of lacquerwares reached its peak between the Warring States Period and the Han Dynasty (390–87 bc ) in the Changsha region of China. By studying excavated fragments of lacquers from this period, this paper examines the constitution of various pigmented layers, such as red, black and white layers, coloured lacquer layers, namely reddish brown or reddish orange, dark‐coloured or black, and silver lacquer layers, using non‐destructive methods. In addition, the characteristics of lacquer production techniques in Changsha are also discussed in comparison with those of other regions in China during the same period of time.  相似文献

Historically, development in Brazilian Amazon was promoted by permits of deforestation under soft territory control or supervision. However, due to the importance of this biome for biodiversity and ecosystem balance in a global perspective, Brazilian's government has tightened deforestation control. This work investigates the spatial pattern of deforestation in a cross‐section and time perspective using global and local spatial data analysis. Global results indicate the existence of high spatial correlation and that deforestation holds concentrated across space, despite the efficacy of policy mechanisms adopted for controlling and reducing the level of deforestation in Legal Amazon. Furthermore, local results support the hypothesis of high spillover effects. Considering the spatial analysis results, we highlight some implications for policy design aiming deforestation control.  相似文献

ABSTRACT

The aim of this article is to analyze two Spanish documentary films that reflect on the 2008 financial crisis in Spain, Mercado de futuros (Mercedes Álvarez, 2011) and No estamos solos (Pere Joan Ventura, 2015). These movies could be marked as political for their choice of a collective protagonist and for dealing with the issues of inequality with the purpose of appealing to mobilization and resistance to the neoliberal Western agenda that have provoked social cutbacks after the 2008 crisis. Mercedes Álvarez and Pere Joan Ventura follow the tradition of political documentaries traced by filmmakers such as Dziga Vertov, Joris Ivens, Pere Portabella, and Basilio Martín Patino and open the debate on how people can contribute to searching for renewal policies in times of crisis.  相似文献

Abstract

Planning culture has been frequently invoked in recent years to explain the differences in spatial planning across different countries. In discussing planning culture, most contributions emphasize the characteristics and particularities of spatial planning practice in particular contexts. This paper discusses the roles of culture and institutions in relation to the distinct urbanization patterns that have emerged in Flanders and the Netherlands. It concludes that it is not the differences between planning cultures (interpreted as the culture of planners, their ideals and practices and the features of the planning system) that provide the major explanation for different urbanization processes. It is rather the fit between the planning culture and the broader societal culture that seems to be an important explanation for how spatial development is managed.  相似文献

Abstract

The global phenomenon of the birth of agriculture remains an enigma and challenges the role of food storage. Much has been written about their invention. A general explanation is needed for its progression in various parts of the world, which is both sociologically based and founded on the archaeological data. This task led Alain Testart to claim that it was by developing their existing skill sets (foraging, pottery, food storage and small-scale agriculture) that nomadic hunter-gatherers, burdened by an increasingly diverse set of tools and equipment, became sedentary. This sedentarism in turn allowed them to specialise in those activities, which had (literally) weighed them down: notably, breeding the first plant cultivars and, often, storing food.  相似文献

Determining the behavior of a structure estimated by means of finite elements analysis requires not only an in-depth knowledge of its geometry and dynamic properties but also an experimental validation to corroborate the adequacy of the characteristics of the structure. Most of the current structural identification techniques are based on linear methods that call for many measurement points and/or a relative simple structure. Complex structures are somewhat still an unexplored field due to the difficulties with the finite element method and the experimental corroboration of its results. This study presents the use of particle motion computation applied to each structural vibration mode to improve the identification of its dynamic properties, and its application to the Gothic Cathedral of Palma de Majorca (Spain).  相似文献

To date, limited numbers of dental calculus samples have been analyzed by researchers in diverse parts of the world. The combined analyses of these have provided some general guidelines for the analysis of calculus that is non-destructive to archaeological teeth. There is still a need for a quantitative study of large numbers of calculus samples to establish protocols, assess the level of contamination, evaluate the quantity of microfossils in dental calculus, and to compare analysis results with the literature concerning the biology of calculus formation. We analyzed dental calculus from 53 teeth from four Brazilian sambaquis. Sambaquis are the shell-mounds that were established prehistorically along the Brazilian coast. The analysis of sambaqui dental calculi shows that there are relatively high concentrations of microfossils (phytoliths and starch), mineral fragments, and charcoal in dental calculus. Mineral fragments and charcoal are possibly contaminants. The largest dental calculi have the lowest concentrations of microfossils. Biologically, this is explained by individual variation in calculus formation between people. Importantly, starch is ubiquitous in dental calculus. The starch and phytoliths show that certainly Dioscorea (yam) and Araucaria angustifolia (Paraná pine) were eaten by sambaqui people. Araceae (arum family), Ipomoea batatas (sweet potato) and Zea mays (maize) were probably in their diet.  相似文献
