A large sample of human bones from a series of archaeological sites in the south‐eastern Iberian Peninsula was selected for δ13C and δ15N stable isotope analysis. Except for some contrast samples, the remains date from the first half of the second millennium cal BC and are ascribed to the Argar Culture, which developed during the Bronze Age in south‐eastern Iberia. Most authors have considered that this region reached a high degree of social hierarchical organization at this time, as demonstrated by the funerary record, both with regard to the grave goods and to the evidence of physical effort and diseases on the human remains. Results of the isotope analysis revealed the existence of differences among the settlements studied, as well as differences over time within every settlement and among the various individuals tested. Some variances can be assigned to social classes/status and others are linked to chronological factors. In particular, changes in δ13C can be explained by the increasing aridity of the first half of the second millennium cal BC, although other causes can be put forward too.  相似文献

The p‐regions is a mixed integer programming (MIP) model for the exhaustive clustering of a set of n geographic areas into p spatially contiguous regions while minimizing measures of intraregional heterogeneity. This is an NP‐hard problem that requires a constant research of strategies to increase the size of instances that can be solved using exact optimization techniques. In this article, we explore the benefits of an iterative process that begins by solving the relaxed version of the p‐regions that removes the constraints that guarantee the spatial contiguity of the regions. Then, additional constraints are incorporated iteratively to solve spatial discontinuities in the regions. In particular we explore the relationship between the level of spatial autocorrelation of the aggregation variable and the benefits obtained from this iterative process. The results show that high levels of spatial autocorrelation reduce computational times because the spatial patterns tend to create spatially contiguous regions. However, we found that the greatest benefits are obtained in two situations: (1) when ; and (2) when the parameter p is close to the number of clusters in the spatial pattern of the aggregation variable.  相似文献

The excavation of the north house at the archaeological site of Arucci (Aroche, Huelva) has provided interesting data for understanding city planning in general, and domestic architecture in particular. Investigation of their environments has allowed the identification of the distinct functions for which they were intended, including two significant tabernae that were connected to one of the main thoroughfares of the city. In one of them, an interesting set of ceramic fragments has been recovered, whose features allow us to recognize them as ceramic containers for fattening the much-appreciated dormouse. This find signifies an interesting novelty in the archaeological record of the city from which various aspects of the diet of its inhabitants can be inferred, as well as the breeding and production of the rodents.  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

西晋墓葬中出现的镇墓兽是东汉时期出现的独角类镇墓兽的继承和发展。这类镇墓兽常伴有武士俑的出土。而在西晋时期,流行着青牛、髯奴的御鬼辟邪术,这种辟邪观念很有可能就是西晋墓中出土的镇墓兽及武士俑的创作源泉。  相似文献

明朝末期可称作中国版画发展史上的黄金时代。明中叶以后,"市民文化"渐渐充斥着人们的精神世界,各种以图画为主的图谱也如雨后春笋般出现。实时,制墨本为平常之事,然有爱好者将墨的形制、图案进行创新变革,刻成墨模之后,进而印出"墨谱"。虽说"墨谱"的产生源于墨的生产,但其中所表现的些许图像元素和艺术形态却值得研究。文章从明末徽派制墨名家程君房所出墨谱《程氏墨苑》为载体并进行延伸,对其中的图像内容、形态进行浅析,说明了当时社会的艺术理念和审美倾向。各种图形都是作者基于现实或想象思维的一种验证,代表着创作者的思想意识,也是当时社会民众视觉冲击力的一种验证。  相似文献

初中语文教学长期采用“课堂十课外练习”的传统教学模式,学生围绕着教师的指挥棒转,忽视了学生学习语文的创新能力和实践能力的培养,因而学生的创新思维受到束缚,表现出厌学的情绪。要改变这一现状,教师在课堂教学的各个环节中增“趣”添“味”是一种很有实效的做法。它能刺激学生积极去学,有效地提高学生的语文素质,培养学生的创新能力和参与实践的能力。  相似文献

This paper examines an alternative approach to previously proposed models of prehistoric exchange such as the law of monotonic decrement or the down-the-line exchange model developed by Renfrew (Proceedings of the Prehistoric Society 34: 319–331, 1968, Renfrew 1977) to explain the distribution of obsidian across the Near East during the Neolithic period. Renfrew’s down-the-line model, which results in a very regular and clustered network, does not permit the circulation of obsidian to regions of the Near East that are further than 300 km from the source zones, as is shown in the archaeological data available. Obsidian exchange is a complex system where multiple factors interact and evolve in time and space. We therefore explore Agent-Based Modelling (ABM) so as to get a better understanding of complex networks. ABM simulations of an exchange network where some agents (villages) are allowed to attain long-distance exchange partners through correlated random walks are carried out. These simulations show what variables (population density, degree of collaboration between villages…) are relevant for the transfer of obsidian over long distances. Moreover, they show that a type of small-world exchange network could explain the breadth of obsidian distribution (up to 800 km from source) during the Near Eastern Neolithic.  相似文献

Since its appearance in 1879–1880, Juan Moreira has been read as an illiberal novel, casting its eponymous hero (the historical bodyguard and electoral henchman of the same name) as a metaphor for the plight of variously-defined subalterns in liberal and neoliberal Argentina, and a condemnation of the social order they brought about. Contrary to that assumption, and reading the novel in its original context (the newspaper La Patria Argentina, in the months leading up to the Buenos Aires rebellion that would settle the fate of Buenos Aires, and end the cycle of civil wars in Argentina), the article argues that Moreira should be read as an strictly liberal novel, inventing a version of the gaucho not as a premodern barbarian (i.e. Sarmiento’s version) but as the embodiment of a modern liberal notion of subject (and citizen, even citizen-in-arms), produced by a functional market economy and a modernizing state, whose descent into criminality is a consequence and a cautionary tale not of the evils of the liberal order, but of what for Gutiérrez was the illiberal (at the same time conservative and barbaric) embodied in his political opponents presidents Nicolás Avellaneda and Julio Argentino Roca.  相似文献
