The object of this article is to analyse the portrait of emperor Licinius in three important sources of the reign of Constantine the Great: Lactantius' De mortibus persecutorum and, especially, Eusebius' two historical works, the Historia ecclesiastica (HE) and the Vita Constantini (VC). The influence of rhetoric, with the keywords vituperatio/laudatio and progymnasmata, is emphasized in Eusebius' way of depicting Licinius, this great loser in Late Roman History.  相似文献

Globalization did not create convergence to a unique economic model among countries. Even in developed countries, the answers to the pressures of markets underline the existence of a variety of capitalisms. The analysis of innovation systems, in particular at the national level, is adequate as a preliminary approach to understand the diversity of profiles and institutional architectures. The article benefits from the broader notion of national innovation system to understand the profiles of 15 European countries. By analysing central building blocks and institutional complementarities through the creation of indexes based on 64 variables and a cluster analysis, it was possible to understand the different levels of institutional efficiency in the analysed dimensions for the selected groups of countries.  相似文献

This article explores the pervasive impact of the pre-Hispanic past on contemporary Latin American identity, using the Ecuadorian Indian movement and the Yucatacan town of Izamal as two symbolic sites where many of these factors vie for official recognition. Therefore, the central topic of this article is also an essential element of the debate contained within the global development discourse: How is it possible for Latin American to face the constant onslaught of powerful North America and European iconic images and not in some way embody its own inherent internalized forms of colonial oppression?  相似文献

In the second half of the nineteenth century Portugal undertook an ambitious public works programme in order to develop the kingdom. In that programme, railways took a leading role, especially those routes that linked the main ports of the shoreline to Spain (and thence to France). To do so, a strenuous effort of diplomacy – or more specifically technodiplomacy – was required to convince Spain to accept cross-border links that served the goals of Portugal. In this paper I will analyse this technodiplomatic process and how two countries with different technological perceptions of railways managed to settle their differences and build five transnational links across their borders over the course of 40 years. I aim to add to the debate about the Iberian cross-border links from the point of view of the history of technology, in particular, and to the discussion about transnational technological systems, in general.  相似文献

This study represents an isotopic survey of modern plants developed to establish baseline isotopic values in order to explore prehistoric herd management strategies employed by the South American camelid herders that occupied the southern Andean highlands during the past 3000 years. We present carbon (δ13C) and nitrogen (δ15N) isotopic compositions of natural pastures collected from different plant communities along an altitudinal gradient in the dry Puna of Argentina. Our results show that C3 plants are the most abundant along the whole altitudinal gradient and that C3 and C4 plants exhibit a differential distribution, the latter being less abundant in those sites located above 3900?meters above sea level (masl). At the same time, plants growing at low-altitude sites with low water availability exhibit higher δ15N values than plants growing at high-altitude sites with higher water availability. These results explain the negative correlation found between altitude and South American camelid bone collagen δ13C and δ15N values published in previous studies. This work represents a fundamental step towards the building of an isotopic ecology for the dry Puna area with the ultimate goal to explore herd management strategies employed by human groups in the past. In this sense, modern plant and South American camelid tissue isotopic compositions would provide a frame of reference to interpret isotopic compositions measured on archaeofaunal remains recovered at pastoral sites, with the aim to explore mobility and pastureland use by prehistoric herders.  相似文献

Debates about Nietzsche's political thought today revolve around his role in contemporary democratic theory: is he a thinker to be mined for stimulating resources in view of refounding democratic legitimacy on a radicalised, postmodern and agonistic footing, or is he the modern arch-critic of democracy budding democrats must hone their arguments against? Moving away from this dichotomy, this article asks first and foremost what democracy meant for Nietzsche in late nineteenth-century Germany, and on that basis what we might learn from him now. To do so, it will pay particular attention to the political, intellectual and cultural contexts within which Nietzsche's thought evolved, namely Bismarck's relationship to the new German Reichstag, the philological discovery of an original Aryan race, and Nietzsche's encounter with Gobineau's racist thought through his frequentation of the Wagner circle. It argues that Nietzsche's most lasting contribution to democratic thinking is not to be found in the different ways he may or may not be used to buttress certain contemporary ideological positions, but rather how his notions of ‘herd morality’, ‘misarchism’ and the genealogical method still provides us with the conceptual tools to better understand the political world we inhabit.  相似文献

In this paper, three approaches for developing sample-specific sex determination methods of immature skeletal remains based on permanent tooth dimensions are proposed and tested using a sample of identified skeletons. The sample comprises adult and subadult individuals selected from the Lisbon documented skeletal collection, housed at the National Museum of Natural History in Lisbon, Portugal. Faciolingual and mesiodistal diameters were the tooth dimensions utilized. In the first approach, sex-specific logistic regression formulae based on adult tooth dimensions are developed and then used to determine the sex of the subadult sample. The second and third approaches are based on the sectioning point procedure, which uses the overall mean of a measurement (tooth diameter) collected from the sample as the discriminant criteria for determining the sex of the individuals in that sample. While in the second approach the adult overall mean of each dimension is used as the discriminant criteria for determining the sex of the subadults, in the third approach it is the subadult overall mean of each dimension that comprises the discriminant criteria that is applied back to the subadults for determining sex. Results show that the canines are the teeth with the highest sexual dimorphism and methods of sex determination based on canine dimensions provide correct allocation accuracies between 58.8% and 100% depending on the diameter and the approach that is being used. Canine faciolingual dimensions provide the best overall results. Combinations of measurements from the same and different teeth do not increase significantly the accuracy of the methods and approaches. Some of the problems of subadult sex determination methods based on adult tooth dimensions result from differing levels of sexual dimorphism between the adult and subadult segment of the sample. Mortality or cultural bias may increase or decrease the sexual dimorphism of the subadults compared to the adults. Small subadult samples utilized in this study may also raise questions regarding the accuracy of the three different sample-specific approaches. However, high consistency of results using the canine and different approaches, suggests that adult and subadult canine dimensions can be reliable sex discriminators of immature skeletal remains in archaeological samples. The major advantage of the approaches presented here is that they can be used to derive sample-specific methods and, therefore, eliminate the problem of applying morphological or metric methods to individuals originating from a population that differs from the one that contributed to the development of the method.  相似文献

Between 1950 and 1990, housing was the driving force behind the spatial growth of the Randstad. Growth poles (1970s) and later VINEX locations (1990–2010) were the main components of growth management. Transport infrastructure has developed greatly since the 1920s. Since 1990, infrastructure development has increasingly become the structuring force for the spatial dynamics of the Randstad. Schiphol was seen as the mainport for airlines, and Rotterdam-Europoort as the mainport for shipping lines and container transport. The landside infrastructural connections for Schiphol and Europoort had a big impact on the growth in the capacity of continental roads and rail lines. ICT- and energy infrastructure are now developing quickly. Recently, Amsterdam Internet Exchange became the largest ICT node in Europe. Finally, the Delta programme was introduced, strengthening the coastal areas and leaving more room for the rivers. For the future, a combination of housing, infrastructure and water for spatial developments will determine the spatial structure of the Randstad further. A compartmentalized plan of the Randstad between the main dikes is presented, which will increase the resilience of functions of the Randstad in the future when the North Sea level is expected to rise substantially. The analysis presented could be relevant for many urban deltas worldwide.  相似文献
