It has been a feature of the past 30 years or so that individual sovereign states have been increasingly willing to partially set aside their own interests in favour of international treaties on pollution control and wildlife protection. It is the political will of the government signatories to such agreements that is the key to successful implementation as that political will provides the legitimate enforceable authority that is necessary to ensure compliance. This paper examines a trilateral agreement made by the Governments of Denmark, Germany and Holland for the protection and management of the Wadden Sea—one of Europe's most important wildlife sites. The examination of that agreement explores the key mechanisms used for its implementation and, in the case of the Wadden Sea, those mechanisms include the operation of key European Union environmental Directives. The paper finds major differences in approach and application of the Birds, Habitats and Environmental Impact Assessment Directives across the Wadden Sea region and argues that these differences undermine the trilateral agreements made by the three governments. 相似文献

Microscopic examination and analysis (metallography, X‐radiography, SEM–EDS, pXRF and μ‐XRF) of a group of stylistically linked gold alloy pendants from western and north‐western Colombia confirms the use of a highly unusual manufacturing technique for the region. While the Darién pendants were made using lost‐wax casting by a diverse group of cultures from southern Colombia through Costa Rica, only one subset of pendants produced in the Gran‐Zenú region (the Caribbean lowlands of northern Colombia) and the Chocó region (the Pacific area of western Colombia) in the Early Period (ad 0–900) was found to be manufactured by hammering of gold sheet and fine wires followed by hard soldering of components to produce true filigree. Similarities in features between the stylistically related cast and hammered pendants suggest that the hammered pendants may have served as a prototype for the cast versions. Other possible instances of hard soldering in the region are also presented. 相似文献

Abstract: Territory is the quintessential state space and appears to be of growing political importance. It is also a key concept in geography, but it has not been subject to as much critical attention as related geographical terms and remains under‐theorised. Taking my cue from Timothy Mitchell's suggestion that the state should be understood as the effect of social practices, I argue that the phenomenon that we call territory is not an irreducible foundation of state power, let alone the expression of a biological imperative. Instead, territory too must be interpreted principally as an effect. This “territory‐effect” can best be understood as the outcome of networked socio‐technical practices. Thus, far from refuting or falsifying network theories of spatiality, the current resurgence of territory can be seen as itself a product of relational networks. Drawing on an empirical case study of the monitoring of regional economic performance through the measurement of gross value added (GVA), I show that “territory” and “network” are not, as is often assumed, incommensurable and rival principles of spatial organisation, but are intimately connected. 相似文献
