In Latin America, ethnicity is equated with indigenity. It is an objective of this article to review the legacy of Anthony Smith regarding the vitality of the ethnic past and the myth of origin, as the core of his theory of nationalism based on the weight of ethnocentrism. To this end, we address two routes, the use of the ethnic past and ethnicity by nationalists and founders of the state and, how indigenous intellectuals, on the other, have found a reinvention of their identities through various myths of Amerindian origin. Ethnic myths and the use of the ethnic past have been accepted, denied or rejected by nationalists, while indigenous peoples adhere to their own myths or seek to reinvent them. Mythical information is a component of identity but also requires institutions to disseminate such information among the group.  相似文献

The behavior of base-isolated building frame is investigated with the help of a numerical study for far-field and near-field earthquakes with directivity and fling-step effects. Both design-level and extreme-level earthquakes are considered. Selected response parameters are peak floor displacement, acceleration, base shear, and isolator displacement. Inelastic behavior of base-isolated structure during the earthquake is investigated performing nonlinear time history analysis of a ten-story building frame. This study shows that base isolation is not effective for near-field earthquakes. Even for design-level earthquake, the frame gets significantly into inelastic range for earthquakes with fling-step effect.  相似文献

The focus in this article, through a reading of the German-Australian newspaper Der Kosmopolit, is on the legacies of entangled imperial identities in the period of the nineteenth-century German Enlightenment. Attention is drawn to members of the liberal nationalist generation of 1848 who emigrated to the Australian colonies and became involved in intellectual activities there. The idea of entanglement is applied to the philosophical orientation of the German-language newspaper that this group formed, Der Kosmopolit, which was published between 1856 and 1957. Against simplistic notions that would view cosmopolitanism as the opposite of nationalism, it is argued that individuals like Gustav Droege and Carl Muecke deployed an entangled ‘cosmo-nationalism’ in ways that both advanced German nationalism and facilitated their own engagement with and investment in Australian colonial society.  相似文献

This article critically engages with the different politics of memory involved in debates over the restitution of Indigenous Australian ancestral remains stolen by colonial actors in the nineteenth and early twentieth centuries and brought to Berlin in the name of science. The debates crystallise how deeply divided German scientific discourses still are over the question of whether the historical and moral obligations of colonial injustice should be accepted or whether researchers should continue to profess scientific ‘disinterest’. The debates also reveal an almost unanimous disavowal of Indigenous Australian knowledges and mnemonic conceptions across all camps. The bitter ironies of this disavowal become evident when Indigenous Australian quests for the remains of their ancestral dead lost in the limbo of German scientific collections are juxtaposed with white Australian (fictional) quests for the remains of Ludwig Leichhardt, lost in the Australian interior.  相似文献

This paper presents the results from extensive parametric dynamic analyses of soil-structure systems that focus on the clear modification (increase or decrease) of the acceleration amplitude at the foundation with respect to the free-field, especially for squatty structures. Properties of the systems are selected such as to cover a wide range of meaningful geometries and materials for engineering practice. The results are presented in terms of weighted modification factors of the maximum foundation acceleration amplitude with reference to the corresponding maximum acceleration amplitude at free-field, for squatty and more slender structures. For the large majority of the studied systems, foundation acceleration decreases from the free-field by 10–15% on average. Nevertheless, acceleration demand at the foundation increases compared to the free-field, for 30% of squatty and for 15% of the more slender structures. Modification of the foundation acceleration amplitude is also correlated with the ratio of the predominant period of the input motion to the flexible-base system period. Finally, the findings of this study are compared with sparse available recorded data from the Seismic Hazard Harmonization in Europe database.  相似文献

In the early 1970s, the Conference on Security and Cooperation in Europe (CSCE) was the cornerstone of French foreign policy regarding East-West relations. It was considered by Paris as the best way to maintain dialogue with Moscow as well as an instrument to reach the Gaullist goal of overcoming the European status quo. This double objective explains why the French adopted an ambiguous attitude during the CSCE: even though their goal was to challenge the Brezhnev doctrine and initiate a process to meet the aspirations of peoples under Soviet domination, they knew that this would be a lengthy process. For them, it was necessary to avoid provoking the Soviets by putting forward expressively liberal proposals. The French leaders of the 1970s saw the CSCE as the multilateral prolongation of the Gaullist policy of ‘détente, entente, cooperation’.  相似文献

What did peasants discuss at party meetings? Were they mobilized by ethnic politics or indifferent to them altogether? The end of the First World War brought about universal male suffrage in much of Europe, and with it the process of mass politics began. The concept of national indifference is important in understanding interwar politics, because this period is often studied teleologically with attention focused on extremism and nationalism as the primary mobilizing issue

Agrarian movements have been under-researched, and when Agrarians have been studied, it has been through the prism of elite politics. This comparative paper seeks to redress this omission by looking at grassroots rural politics. The interwar countryside was marked by profound political, economic and social transformation but also in terms of what Robert Paxton has described as the ‘triple crisis of the countryside’ – worsening economic conditions, the declining status of the countryside and inadequate political representation. The paper will explore how reform and crisis impacted how agrarian politics functioned at a local level by asymmetrically comparing cases from Romania, Poland and Ireland, with the final case helping to contextualize Eastern Europe within the wider European experience This paper argues that the rural population was mobilized, but primarily in the context of local issues rather than national ethno-political questions. Local party organization was, to paraphrase James C Scott, the site ‘of an exchange of small arms fire’ in rural class conflict, as questions regarding the control of public space, generational conflict and power within the village mobilized peasants. Thus, I argue that it was the underlying socio-economic issues that mobilized the rural population, not nationalism. The dynamics of these conflicts were shaped by local economic, political and social power dynamics, and by using indifference as a concept, we can look more deeply at interwar politics from a grassroots perspective and develop a more nuanced understanding of local, national and European politics.  相似文献

ABSTRACT

In 2014, an interesting youth movement collective started small p political and big P Political action and resistance in Taiwan. Their protest was against the way a major trade agreement proposed between China and Taiwan was being non-democratically pushed through the Taiwanese legislature. In this article, we provide an analysis of the activities of the Sunflower Student Movement (SSM) as a means to record a relatively little-known youthful and youth-centric successful uprising. It serves to place the SSM, and other East Asian-based protests, on the map of young people’s political geographies, and explores the paradoxical political and spatial practices pursued by young Taiwanese. This case study makes visible the interconnectedness of big P/small p politics of everyday youth geographies within an Asian context.  相似文献

ABSTRACT

The free trade agreement (FTA) between Australia and the European Union holds the promise of strengthened political collaboration and increasing economic integration. Both Australia and the European Union note increasing bilateral trade and investment. Oftentimes, data does not take current trends in global-value-chain participation for intermediary goods and services movements into account. Behind this sit the cross-border strategies and activities of business entities, whether multinationals or large, small or medium-sized enterprises. This article provides an in-depth investigation of the premise stemming from an FTA for Australian business. What advantages can politics hope to support through a business perspective? What is the global-value-chain part of the story, and what are the business challenges ahead? How can economic policy help shape this FTA to foster a productive bilateral business environment in a geopolitical and geoeconomic context in which regionalisation has taken on new momentum? Specific focus is given to the analysis of the higher education sector and to agriculture. These are two of the leading sectors in this FTA debate. Generating business value means setting negotiation agendas to target tariff and non-tariff barriers to counterbalance ambiguity in the conditions that shape the global business environment.  相似文献
