This paper investigates the social structure of an Early Bronze Age society whose members were buried at the necropolis of Mokrin (Serbia, Southeastern Europe), by comparative analysis of musculo-skeletal markers (MSM) of activity and social status as induced on the basis of grave contents. The main objective of the analysis is to determine whether quantitative and qualitative differences in activity are related to social status. Besides using an overall measure of activity, we attempted to isolate different qualitative aspects (facets) of activity through factor analysis of MSM scores. No correlation between social status and overall labor intensity was found. However, there are clues that social status and a single facet of activity are related. Positive correlation between vertical status and the intensity of use of upper arm and shoulder muscles was found among male individuals, while negative correlation between the aforementioned variables was found among the females. The general conclusion based on the results of this study is that there is no simple correlation between the overall labor intensity and social status. 相似文献

Great Moravia existed in central Europe from the ninth to the early tenth century and left behind a lasting legacy in central and eastern Europe. However, the interpretation of the early medieval history of the region has always been a delicate matter. The written sources concerning Moravia do not lend themselves easily to historical interpretation. As a consequence, they have often been invoked not just for academic, but also for political debates. For modern state ideologies to effectively exploit the historical heritage of Great Moravia, two conditions must be met. First, there should be absolutely no doubt as to whether Great Moravia encompassed precisely those territories now within the borders of the states claiming to be its direct heirs. Second, firm evidence of politically advanced structures of power is required in order to justify both the name of 'state' and continuity to the modern age. The goal of this paper is to prove these premises on the basis of the archaeological evidence. 相似文献

This paper explores the role of Hispania in the Atlantic route in Roman times. We analyse the different Atlantic Iberian territories along this route, based on recent archaeological advances and discoveries related to trade as well as the shipping infrastructure. The aim is to explain the origin and evolution of a new maritime area that was completely integrated with the political and commercial structure of the Empire, with trade routes that followed the coastal areas of the Iberian Peninsula all the way to the Mediterranean. 相似文献

The extent to which Francisco Antonio Moreno y Escandón’s plan of the Viceroyalty of Santafé sparked a revival of cartographical activity has hitherto been overlooked. The Viceroyalty of Santafé was created as a major unit in the Spanish Empire in 1739 and included the present-day countries of Colombia, Ecuador, Venezuela and Panama. Moreno, a high-standing Creole functionary, mapped the region in 1772 in the context of its administrative organization. By drawing attention to Moreno’s official map, I hope to encourage the study of late-colonial and early-republican cartography of the northwestern part of the former Spanish-American dominion and the present-day constituent republics. 相似文献

ABSTRACTTeresa de Jesús (1515–1582) lives in a patriarchal society opposed to the intellectual and spiritual development of women, something that she will not only not accept but also fight against, claiming a series of rights (the right to life, to expression, to autonomy, to the free development of her abilities, to have an active role in the Church, to relate to God through prayer, etc.) in spite of the restrictions of censorship and the cloud of suspicion that hung over her for being a mystic, the founder of convents, and the daughter and granddaughter of a converso. Furthermore, Teresa, with her reforms, would present an alternative life for women, as her convents would be spaces for freedom and women's solidarity. 相似文献

This paper explores the effectiveness of policies ‘in’ attracting the foreign research and development (R&D) of multinational enterprises (MNEs) to specific countries in Europe. We develop a macroeconomic investigation covering 29 European countries during the period between 1990 and 2012 in order to address: (a) whether the provision of direct financial support for business R&D is effective for the attraction of foreign R&D; (b) whether direct support is more effective than indirect support for this purpose and (c) whether the link between direct financial support for business R&D and the foreign R&D of MNEs is conditioned by the context within which the support is provided. The results of the analysis show that, first, the provision of direct financial support is generally effective for the attraction of foreign R&D by MNEs. Second, direct support for business R&D is more effective for this purpose than indirect support. Third, the provision of direct financial support for business R&D yields greater returns in contexts that are more socio-economically suitable for knowledge-intensive, innovative activity. 相似文献

Gender differences in mobility patterns between women and men have long been acknowledged. This study analyses how these differences are reproduced in different urban and rural contexts. Using mobility data from a large travel survey taken in 2006 in Spain, we examine the differences between gender mobility through age, modal split and trip purposes. Special attention is paid to how territory shapes mobility and how these territorial settings differently affect gendered mobilities. The use of this data source allows the comparison of all trips made by the total population, including all means of transport. By taking a global view on mobility, the uneven relationships that men and women have with different means of transport become more visible. After disaggregating data by age and territorial settings, results show that women are using sustainable transport modes more often than men, and travelling for more diverse reasons. Gender is thus a fundamental variable in understanding modal split and, by extension, transport sustainability, in terms of energy consumption and the emission of greenhouse gases. From this point of view, we consider women's mobility knowledge and practices – typically related to the most sustainable means of transport – as factors with rising value that could effectively guide public policy in its way to promote more sustainable mobility patterns. 相似文献
