Herding and farming coexisted in Central Asia for several thousand years as main options of preindustrial economic production. The relationship between people practicing different variants of these modes of subsistence is known to have been dynamic. Among the many possible explanations, we explore this dynamic by modeling mechanisms that connect aggregate decisions to land use patterns. Within the framework of the SimulPast project, we show here the results from step 1 of our modeling program: the Musical Chairs Model. This abstract agent-based model describes a mechanism of competition for land use between farming and herding. The aim is the exploration of how mobility, intensity, and interdependence of activities can influence land use pattern. After performing a set of experiments within the framework of this model, we compare the implications of each condition for the corroboration of specific land use patterns. Some historical and archaeological implications are also discussed. We suggest that the overall extension of farming in oases can be explained by the competition for land use between farming and herding, assuming that it develops with little or no interference of climatic, geographical, and historical contingencies. 相似文献

Traditional timber frame walls are constructive elements representative of different timber frame buildings, well known as efficient seismic-resistant structures. They were adopted as a seismic-resistant solution in Lisbon’s reconstruction after the 1755 earthquake. To preserve these structures, a better knowledge of their seismic behavior is important and can give indications about possible retrofitting techniques. This article provides a study on possible retrofitting techniques adopting traditional solutions (bolts and steel plates). Static cyclic tests were performed on retrofitted traditional timber frame walls. The experimental results showed the overall good seismic performance of steel plates and the more ductile behavior of bolts retrofitting. 相似文献

In this article, we argue that the Cultural Theory pioneered by Mary Douglas can help resolve two pressing issues in the study and practice of public deliberation. The first of these issues concerns how best to structure deliberative processes (or “minipublics”) that have increasingly been implemented around the world. We use Cultural Theory's analysis of social relations to derive a hypothesis concerning the ideal design of minipublics, and outline research strategies to test the hypothesis. The second issue pertains to scaling out minipublics. We describe John Dryzek's and Simon Niemeyer's influential proposal for deploying discourses to make public deliberation more representative, and discuss the limits of their proposal. Furthermore, we show how Cultural Theory's analysis of people's cultural biases (i.e., collectively shared perceptions, beliefs and norms) may help overcome these limits and how the design of minipublics can generate trust in and legitimacy of public deliberation. 相似文献

Special buildings used as saunas have been found in certain large hillforts in the north of Portugal and in the Cantabrian coastal area of Asturias and Galicia in Spain. The principal aim of this study is to highlight the importance of these buildings in the archaeology and art of the European Iron Age, where they are very rarely mentioned. Two approaches are developed: in Parts 1 and 2, we explain the structure of the buildings, their function, and the current debate surrounding their dating. In Parts 3 and 4, further analyses are developed on their position in the landscape, associating the saunas with the public life of the hillforts, and on the decorative structure of the pedras formosas (‘beautiful stones’) found in some of them, and their relation to certain artistic trends in so‐called Celtic art. 相似文献

This study shows the results of a multidisciplinary collaboration between the University of Calabria (Italy) and the National Autonomous University of Mexico (UNAM), about the compositional characterization of some mortars taken from Hagia Sophia in Istanbul (Turkey), one of the most important buildings in antiquity. Twenty samples of joint mortars were analysed by micro-chemical analyses (SEM-EDS), X-ray powder diffraction (XRPD), optical microscopy (OM) and transmission electron microscopy (TEM). The compositional study allowed us to define, with more detail, the construction phases of the fifth, sixth and tenth century. The petrographic analysis in thin section by optical microscopy showed four typologies of sands, used as aggregate, with specific compositional features. SEM-EDS analyses and TEM observations of the binder around the ceramic fragments of the aggregate showed the presence of different morphologies of single C-S-H compounds. 相似文献

耶稣会士郎世宁于1715年至1766年供职于清廷内务府期间,将两种截然不同的艺术文化融合在一起:欧洲艺术风格是这位艺术家所受的基础训练,中国艺术风格则促成了他的职业成就。本文在分析郎世宁意大利基础训练及绘画知识的同时,也分析了其在清廷的代表作品,以提供这位画家在中国进行文化融合的基本框架。郎世宁的文化融合证明,他所接受的意大利基础训练与其后来作为宫廷画家所取得的成就之间,有着深远的联系。本文讨论了郎世宁全部绘画作品中不同元素之间相互关联的动态系统。这些相互关联的元素主要包含三方面的背景:绘画的、政治的以及感性的,分别与三种绘画流派有关——风景画、肖像画以及通景画,这一点对于理解郎世宁的事业至关重要。从更广义的角度讲,本文的目的在于通过展示郎世宁的艺术生涯,有助于我们勾勒出18世纪促成中国与欧洲文化艺术碰撞中的联结点。 相似文献

The fruit (pods) of Prosopis (Fabaceae) are frequently recovered from pre-Hispanic Argentinian archaeological sites, suggesting that this genus was of importance in ancient economies in this region. Yet it is only recently that archaeobotanists have begun to carry out systematic research into this genus. Therefore many questions remain to be addressed concerning the food value of Prosopis fruit, and its potential contribution. This paper examines starch from the pods of two species, Prosopis flexuosa and Prosopis chilensis, for the purposes of describing and classifying their morphological features and biometrical parameters. Pods of both species were gathered from two extremes (northern and southern) of the Hualfín Valley, Catamarca, Argentina. Starch abundance is estimated and compared with that of Zea mays, an economically important plant with high concentrations of starch. This paper reveals that Prosopis pods contain very low amounts of starch compared to starch-rich edible species. Despite this, the recovery of Prosopis starch grains can be successfully used to assess archaeological tool uses. Prosopis starch grains were found to be highly variable in shape. Grain size ranged between 10 and 20 μm. Granule irregularity and the high birefringence under polarized light are two of the most important diagnostic features. No significant statistical differences were found in the structure (morphology, size and hilum) of the starch of the same species from both localities. Finally, the implications for the role of this plant in past societies are discussed. 相似文献

This paper explores how mechanical properties of different South Asian tree taxa might influence charred wood fragmentation
and the composition of charcoal assemblages retrieved from archaeological contexts. The dataset is composed of selected plant
species that were collected in Gujarat (Northern India) in September 2007 as part of the North Gujarat Archaeological Project.
The taxa analysed represent the most common wood species found in the arid thorn scrubland formation in South Asia and are
among the most abundant identified in Neolithic and Chalcolithic archaeological sites in this area. The specimens have been
measured and subsequently charred at three different temperatures, under constant conditions. Afterwards, their resistance
to compression has been measured on two planes, parallel and perpendicular to the direction of fibres, using a Hounsfield
5-kN machine. The tests were performed in order to understand the different response to compressive stress of wood that has
been subject to a range of thermal degradations. The standardised treatment applied to the samples has permitted the comparison
of results and the delineation of simple correlations and divergences among the species analysed. Furthermore, the utilisation
of a relatively simple operating protocol easily allows the addition of further data in the future. The applied protocol was
specifically designed to answer archaeological questions. Therefore, even though from a material science point of view some
of the measurements were not taken according to the prevailing standard procedures, it offers valuable data for anthracological
research applied to archaeology in arid zones. 相似文献
