The agrarian transformations which took place in the Iberian Peninsula between the eighth and the tenth century are essential for an understanding of how al‐Andalus came into being. These developments provided the basis of a social formation which developed into a tributary mode of production. This study is part of a research project that draws inspiration from the tenets of landscape archaeology. Studying historic landscapes as part of the material culture of past societies provides valuable information about cultures and the ways they express themselves in space.  相似文献

This article offers a discussion of nuclear doctrines and their significance for war, peace and stability between nuclear‐armed states. The cases of India and Pakistan are analysed to show the challenges these states have faced in articulating and implementing a proper nuclear doctrine, and the implications of this for nuclear stability in the region. We argue that both the Indian and Pakistani doctrines and postures are problematic from a regional security perspective because they are either ambiguous about how to address crucial deterrence related issues, and/or demonstrate a severe mismatch between the security problems and goals they are designed to deal with, and the doctrines that conceptualize and operationalize the role of nuclear weapons in grand strategy. Consequently, as both India's and Pakistan's nuclear doctrines and postures evolve, the risks of a spiralling nuclear arms race in the subcontinent are likely to increase without a reassessment of doctrinal issues in New Delhi and Islamabad. A case is made for more clarity and less ambition from both sides in reconceptualizing their nuclear doctrines. We conclude, however, that owing to the contrasting barriers to doctrinal reorientation in each country, the likelihood of such changes being made—and the ease with which they can be made—is greater in India than in Pakistan.  相似文献

The UN conference to negotiate an Arms Trade Treaty (ATT) concluded on 27 July 2012 without reaching consensus on the text of a draft treaty and saw both the US and Russia calling for more time to negotiate. The ATT process marks the latest in a series of attempts to insert human security concerns into arms export controls. The setback in July raises questions about the current level of international support for the human security agenda, as well as the relative power of different actors to shape global governance structures. This article locates the ATT negotiations in the broader history of multilateral efforts to regulate the international arms trade, from the 1890 Brussels Act to post‐Cold War initiatives. The historical record shows that such efforts are more likely to succeed if they are negotiated or imposed by major arms exporters. The introduction of human security concerns, as well as the merging of export control and arms control agendas, went some way towards reversing this trend. In particular, it created a broad international coalition of supportive states and NGOs from the global North and South. Yet disagreements over the purpose of an ATT remained. The draft ATT included human security provisions, but China, Russia, the US and a number of emerging powers ensured that state security considerations remained paramount in decision‐making on arms exports. The US was the first major actor to announce its unwillingness to sign the draft ATT in July 2012 and two alternative interpretations of US actions are considered. The article concludes by considering the options available to supporters of the ATT process following the 2012 conference and examines the notion that the ATT campaign has become an initiative ‘out of its time’, one that might have had success in the 1990s but not in current circumstances.  相似文献

The Cu–Fe mining district of Servette is located in the valley of Saint‐Marcel (Val d’Aosta) at about 1800 m a.s.l. in the western Italian Alps. A large furnace slag deposit occurs near the Servette mine. Slags are mainly constituted by silicate and oxide in a glassy matrix, with disseminated sulphides and iron–copper alloys, and they record temperatures of 1380–1100°C. Radiocarbon dating of slag charcoals has shown that metallurgy in this site took place around ad 890–980. The charcoal analysis has shown that coniferous wood was mainly utilized, and intensive exploitation over the centuries led to a change in the composition of the local woods.  相似文献

This article re‐examines the EU's character and potential as a strategic actor, setting that analysis in the context of the debate on strategic culture. The definition of strategic culture as the political and institutional confidence and processes to manage and deploy military force, coupled with external recognition of the EU as a legitimate actor in the military sphere, lends itself to a reappraisal around four core questions. First, military capabilities: establishing a European strategic culture is vital in order to rationalize the acquisition of capabilities necessary for the range of humanitarian and peacekeeping tasks envisaged. Equally, without military capabilities, all talk of a strategic culture would ring hollow. This article discusses how much closer the EU has come to acquiring those essential capabilities. Second, while the EU has gained significant experience of, albeit limited, military/policing experiences and established a growing reputation and some credibility for ad hoc action, to what extent and in what quarters have these experiences engendered a sense of reliability and legitimacy for autonomous EU action? Third, given that so far operations in the Democratic Republic of Congo and the Balkans have depended on an integrated civil–military effort, do the policy‐making processes of the EU now ensure the appropriate level and depth of civil–military integration? Finally, considering that EU operations have been limited in time and scope, and that much of the EU's work in the Balkans has depended upon cooperation with NATO, what can be said of the evolving relationship between the EU and NATO?  相似文献
