It is proposed that there is an iconographic and epistemological relationship between some drawings in Felipe Guaman Poma de Ayala’s Nueva corónica y buen gobierno and the images recorded in several colonial wood vessels (qeros) which circulated widely during the time that Guaman Poma was writing his letter to the King of Spain. This connection shows that the work of Guaman Poma was not an isolated or singular act in the colonial context and that both communicative and creative processes, that of the Nueva corónica and that of the qeros, formed part of a process of shared colonial semiosis through which Andean societies maintained a certain autonomy in the production and circulation of their own discourses. Secondly, the article discusses the epistemological tension that results from the coexistence of different narratives (European and Andean) that used their own temporal and spatial categories to account for new colonial conditions.  相似文献

Throughout the 1960s, Spanish students staged a strong opposition against the dictatorship of General Franco. Also during this decade, the U.S. Foreign Service in Spain began to pay great attention to these students for two key reasons. On the one hand, student protests posed a threat to US defensive interests in a country with a high strategic value during the Cold War in southern Europe. However, on the other hand, campus agitation could lead to positive effects for the United States if students’ expectations of social change were channeled toward national development in a context of order and political stability. So, how could student activism and idealism be directed toward a controlled modernization of Spain? This article attempts to answer this question by studying American programs aimed at disseminating the principles of modernization theory in Spanish universities as an instrument to (1) influence students’ political and intellectual socialization and to immunize them against radical ideologies and (2) channel students’ aspirations towards constructive and responsible reform of their country's socioeconomic structures.  相似文献

This article presents the life stories of six indigenous women from the Amazonian region, who coordinate local women processes through indigenous organizations and networks. Since the political and legal visibility of violence against indigenous women in Colombia is weak and limited, we aim to analyze their experiences from an intersectional perspective. For this purpose, we employed multiple methodologies, including body mapping and social cartography. Thus, by reconstructing their experiences and attempts to make visible violence against them, we could perceive some of its multiple modalities, which are quickly captured by the great category.  相似文献

This paper explores regional (département or NUTS3) income inequality in France between 1860 and 1954. To this end we first document the existing evidence, evaluate the estimation methods and findings, assess the suitability of each approach and address potential concerns. We then present our own subnational estimates of per-capita income, derived following Geary and Stark. Overall, we find that indirect estimation (or top-down) methods provide somewhat differing results, thereby calling into question the validity of some of these approaches. Our estimates, meanwhile, appear to fit reasonably well with direct estimations (or bottom-up) of value-added and income and provide evidence in support of a decline in regional inequality over the period of study.  相似文献

The measurement of stable carbon (δ13C) and nitrogen (δ15N) isotopes of caprine bone collagen from the Neolithic sites of Çatalhöyük and Aşıklı Höyük in south-central Anatolia have allowed examination of exploitation and herding practices of sheep and goats. The isotope values from protodomestic caprines at Aşıklı Höyük suggests that these animals were consuming very similar foods to each other and were all confined to the same or similar environments with no access to C4 plants. At Çatalhöyük, the results show how the caprine management strategy develops from the strategy seen at Aşıklı Höyük into a more varied practice at an early stage as the site grows with an increasing dietary contribution obtained from C4 plants. No change in diet is isotopically discernible at Aşıklı Höyük. Interestingly, no distinction could be made between the diets of sheep and goats at either site. Therefore, such studies are a useful method of examining the development of early herding or management strategies of caprines in the Near East.  相似文献

Much of the recent academic literature on spatial planning in Europe focuses on either cross-national comparison of planning frameworks and planning practices or on transnational and transregional initiatives and their impact on planning in European countries. From those publications, it can be gleaned how similar themes are translated differentially in different national contexts. Although it is also a great source of European integration and harmonization, the phenomenon of the knowledge exchange within transnational expert networks of European planners at the level of cities has received less attention. In this paper, the knowledge exchange among planners in such a network is studied, highlighting the role of “transfer agents” (academic and/or policy experts operating in communities in different policy arenas) in the exchange process. It builds on the insights from existing literature on policy transfer and policy learning, and tries to add a new perspective on this body of literature from an insiders' perspective, i.e. participatory observation. The idea is that policy transfer can be fruitfully approached as a process of knowledge and information transfer between producers, senders, facilitators and recipients. Often this exchange is to a very large extent a process of absorbing appealing labels for policy solutions from the international or national policy levels, and then adopting an interpretation of it suitable to one's own context. The authors try to give meaning to this exchange process by using two mechanisms, i.e. social interaction and conceptual replication. By combining these two mechanisms the authors try to uncover which policy lessons are being transferred among seven European cities that joined the expert network on European sustainable urban development (Pegasus).  相似文献

This article analyses the evolution of Community expenditure, on the basis of the data given in the budget and in the EDF, from the origin of the process in 1957 until the year 2002, the last definitive figures. The technique of principal component factor analysis has been applied to these variables. The basic objective of this study is to detect the interrelationships among the policies of the Union and to effect a classification of them, in order to detect the priorities of the European project and to estimate the dimension of the impact of its policies during the period.  相似文献
