Current public policy debates on energy security are characterized by a singular focus on questions regarding access to resources. This lopsided attention to the geopolitical dimension of energy security is based on the myopic and erroneous presumption that global energy politics is necessarily a zero-sum game in which one country's energy security is another's lack thereof. In fact, debates deflect attention from the real issues that policy-makers should consider in their attempts to foster effective global energy governance—the central role increasingly international energy markets play in balancing demand and supply—and, even more importantly, the significance of the 'rules of the game' that structure these markets. This article makes a first attempt to apply a broader analytical lens by pointing out and analyzing the important role rules play in determining outcomes in international oil and gas markets; by examining how current trends are affecting the existing 'rules of the game'; and by highlighting consequences for public policy.  相似文献

Deciphering patterns and inferring processes in multicausal floodplain river ecosystems is a challenge in river science. The effects of larger‐scale top‐down constraints and smaller‐scale bottom‐up influences on the spatial patterns of nutrient concentrations across multiple inset‐floodplain surfaces was studied in a large dryland floodplain river (Barwon‐Darling River, south‐east Australia). The distribution of sediment‐associated carbon, nitrogen, and phosphorus was primarily related with significant differences in the textural character of the different floodplain surfaces. Elevation of the different floodplain surfaces above the active channel was a secondary influence on the distribution of carbon and phosphorus. Combined, these factors produce a spatial patch mosaic of sediment associated carbon, nitrogen, and phosphorous across these floodplain surfaces.  相似文献

NATO has been a source of influence on British nuclear policy and strategy since the 1950s. The nature and extent of its influence has, however, been kept limited by successive British governments. This article considers how and why this has happened. It discusses evolving British attitudes towards NATO command and planning, and shows how these were reflected with regard to strategic nuclear issues from the late 1950s. The evolution of the key notion that the United Kingdom is a second centre of nuclear decision within NATO is traced, and both its utility and contradictions are examined. Overall it is argued that, both during and since the Cold War, NATO has neither been a central factor in shaping British nuclear strategy and policy, nor have British nuclear weapons been other than of limited importance and relevance for most NATO members.  相似文献

The United Nations (UN) and the African Union (AU) have collaborated in building a viable African Peace and Security Architecture and have worked together in a number of armed conflicts over the past decade. Examples include the peace operations in Burundi and Somalia, and the hybrid peace operation in Sudan's Darfur region which is perhaps the most prominent illustration of this collaboration. Although the UN Security Council authorized the intervention in Libya, which was approved by leading regional organizations (the Arab League, the Organization of the Islamic Conference and the Gulf Cooperation Council), it was opposed initially by the AU although the three African states in the Security Council voted for it. Relations cooled as a result and have grown colder still as the UN snubbed the AU and its initial efforts to engage in post‐conflict stabilization in Mali. While the AU sought to prove itself as a capable security provider and partner on the continent with its operation AFISMA, France's Opération Serval and the UN's peace operation for Mali, MINUSMA, bypassed the African Union. This article explores the underlying fault‐lines between the two organizations by examining interactions between the UN and AU since the latter's launch in 2002, but focusing on the Mali case. The fault‐lines emerging from the analysis are different capabilities, risk‐averse vs risk‐assuming approaches to casualties, diverging geopolitics and leadership rivalry.  相似文献

This article aims to shed light on the background to a media event that occupied the world press, and even more the digital media, for a few weeks at the end of last year. The trope of the violent ‘murder’ of a white missionary by one of the last ‘uncontacted tribes’ is likely to evoke a variety of Western projections. Ultimately, it is about power over images, interpretations and how we want to behave towards isolated groups of people in today’s world: leave them alone? Protect them from the culture of violence at the fringe of their territories or contact them now and support them in the long term? An anthropological reading of the case does not lead to a simple answer to this question, but it might help in getting a more informed perspective on a complex subject matter.  相似文献
