The battle against climate change has placed decarbonised capitalism on the economic, political and social agenda. But the shift towards a regime of accumulation compatible with measures to mitigate climate change raises major issues regarding prosperity and power, on a human and political scale never previously entertained. The paper places climate change in the context of the dynamics of the system which caused that change, namely capitalism. The ecological crisis is one manifestation of the crisis gripping the present regime of accumulation, which has reached a financialised, globalised stage. This being the case, any attempt to halt climate change, far from being an environmental issue, must be seen as a problem for the development model of both North and South.
应对气候变化的斗争已将脱碳资本主义提上了经济、政治和社会议程。但是,向与减缓气候变化措施相适应的积累机制的转变,在人类和政治层面上提出了有关繁荣和权力的重大问题,这是以前从未考虑过的。这篇论文将气候变化置于导致这种变化的系统的动态背景下,即资本主义。生态危机是当前积累体制所面临的危机的一种表现,它已经达到了金融化、全球化的阶段。在这种情况下,任何阻止气候变化的努力,都绝不是一个环境问题,而必须被视为南北双方发展模式的问题。

The second Earth Summit in Rio will open in 2012. The debate will concern the ability of the world to face its future and the participants will hope to provide answers. Climate change and its challenges will be on the agenda, and recommendations will be advanced and the aim will be to implement them quickly. More than any other area, the climate negotiations have all the ingredients that cause deep divisions in the world and highlight different ways of thinking. The extent of the work needed to change course is huge: it is nothing less than a break with a system of accumulation and techno-economic paradigm that is attached to a commitment to low-carbon societies. However, wanting to involve the poor countries in the world to save the climate now, without meeting their pressing needs for life’s essentials, can only lead to stalemate.
第二届地球峰会将于2012年在里约召开。辩论将涉及世界面对未来的能力,与会者将希望提供答案。气候变化及其挑战将被提上议程,会议将提出建议,目标是迅速实施这些建议。与其他任何领域相比,气候谈判具有导致世界上存在深刻分歧的所有因素,并突出了不同的思维方式。改变方向所需的工作范围是巨大的:这无异于与致力于低碳社会的积累体系和技术经济范式的决裂。然而,想让世界上的贫穷国家现在参与拯救气候,而不满足他们对生活必需品的迫切需求,只会导致僵局。

Climate, a crossroads negotiation 气候,一个十字路口的谈判
Pub Date : 2012-05-04 DOI: 10.1504/AFP.2012.046735
Michel Rogalski
Conscious for 30 years of the prospect of climatic reheating and the harsh changes associated with it, the international community has tried to set up a world climatic architecture likely to slow down and contain, at acceptable levels, the foreseeable evolution. A stack of agreements (Rio 92, Kyoto Protocol, Copenhagen and Cancun Summits) resulted from these international negotiations, mixing scientific controversies, responsible factors, uncertainties about national consequences and questions on the coordination of economic instruments which have to be at the same time effective and right. These negotiations reveal a world undergoing fast change, and the persistence of a North-South antagonism. They crystallise different visions concerning the apprehension about time and strongly question the models of development which have been set up.
30年来,国际社会一直意识到气候再升温的前景及其带来的严峻变化,并试图建立一个能够在可接受的水平上减缓和遏制可预见的演变的世界气候架构。这些国际谈判产生了一堆协议(里约92,京都议定书,哥本哈根和坎昆首脑会议),混合了科学争议,负责任的因素,关于国家后果的不确定性以及必须同时有效和正确的经济工具协调问题。这些谈判揭示了一个正在迅速变化的世界,以及北南对抗的持续存在。它们使人们对时间的理解产生了不同的看法,并对已经建立起来的发展模式提出了强烈的质疑。

Man and the course of the spaceship Earth 人类和宇宙飞船地球的航线
Pub Date : 2012-05-04 DOI: 10.1504/AFP.2012.046734

Through their increasing impact, people have been weighing decisively on the course of the spaceship Earth. The entry into a new geological era, the anthropocene, marks an unprecedented disruption in the long history of the co-evolution between our species and the biosphere. Our immediate task is to draw long-term development strategies, environmentally sound and socially inclusionary, at the opposite of strategies based on the free interplay of market forces. Thus, we must give, within each nation and between nations, the utmost priority to an aggiornamento of long-term democratic planning as the main instrument of governance. The success of the second Earth Summit, due to take place in 2012 in Rio de Janeiro, will largely depend on the participants’ ability to take inspiration from these principles.
通过它们越来越大的影响,人们一直在果断地权衡地球宇宙飞船的路线。人类世进入了一个新的地质时代,标志着人类与生物圈共同进化的漫长历史中出现了前所未有的中断。我们当前的任务是制定与基于市场力量自由相互作用的战略相反的无害环境和包容社会的长期发展战略。因此,我们必须在每一个国家内部和国家之间给予最优先的重视,把长期民主规划作为主要的管理工具。将于2012年在里约热内卢举行的第二届地球峰会的成功与否,将在很大程度上取决于与会者能否从这些原则中汲取灵感。

This paper describes the main stages of the climate negotiations since the Earth Summit in Rio in 1992. After recalling the main components of the Kyoto Protocol, it describes the stakes in the discussions for developing countries as well as the increasing importance taken by these countries. It finally explains how the logic of binding commitments to reduce emissions, which was at the core of Kyoto negotiations, seems to be shifting to a logic of voluntary national reduction commitments.
本文描述了自1992年里约地球峰会以来气候谈判的主要阶段。在回顾了《京都议定书》的主要组成部分之后,它描述了讨论对发展中国家的利害关系,以及这些国家日益重视的问题。它最终解释了京都议定书谈判的核心——约束性减排承诺的逻辑,似乎正在转向国家自愿减排承诺的逻辑。

Are sensitive technologies enablers of civil nuclear power? An empirical study 敏感技术是民用核能的推动者吗?实证研究
Pub Date : 2010-02-08 DOI: 10.1504/AFP.2010.031495
P. Nelson, Christopher Sprecher
In order to better understand, quantitatively and objectively, the factors that have been associated with the extent to which a given state relies on nuclear energy to generate electricity (termed 'nuclear reliance' (NR)), regression analysis was applied to a set of 14 hypothesised independent variables having associated measures constructed from a database assembled for this purpose. That process led to a linear model with five independent variables that collectively predict NR with high confidence (p < 0.05, for all predictors) and acceptable goodness of fit (R² = 0.53). This basic linear model was then employed as a tool to analyse several more-or-less current topics related to proliferation. These include the historical effectiveness of the nonproliferation regime, as regards the spread of sensitive fuel-cycle technologies; the premise underlying (fuel) assurance programmes, as intended to ensure access to (insensitive) nuclear materials and technology, in return for forgoing development of sensitive technologies; and the persistent lack of recipient states willing to accept the bargain underlying assurance programmes.
为了更好地定量和客观地理解与特定国家依赖核能发电的程度相关的因素(称为“核依赖”(NR)),我们对一组14个假设的自变量进行了回归分析,这些自变量具有为此目的而组装的数据库中构建的相关度量。这一过程产生了一个具有五个自变量的线性模型,这些变量共同预测NR具有高置信度(p < 0.05,对于所有预测因子)和可接受的拟合优度(R²= 0.53)。然后,这个基本的线性模型被用作分析几个或多或少与扩散相关的当前主题的工具。其中包括防止扩散制度在敏感燃料循环技术扩散方面的历史有效性;(燃料)保证方案的前提,目的是确保获得(不敏感的)核材料和技术,作为放弃开发敏感技术的回报;以及一直没有接受国愿意接受担保计划背后的交易。

The nanoparticles of BaSO4:Eu as detectors for high doses of different ionising radiations BaSO4:Eu纳米粒子作为高剂量不同电离辐射的探测器
Pub Date : 2010-02-08 DOI: 10.1504/AFP.2010.031494

Nanoparticles of a BaSO4:Eu phosphor with a particle size of around 40 nm have been irradiated by 48 MeV 7Li3+, 75 MeV C6+ and 90 MeV O7+ ion beams at the fluence range of 1 ∼ l09–1 ∼ 1013 ions/cm2. The thermoluminescence (TL) glow curves of the irradiated samples were recorded and studied. The microcrystalline form of this sample is included in the study with the aim of reporting a comparative measurement. The TL results of this material in its nano- and microforms exposed to the gamma rays of 60Co are also included and investigated in more detail. It is observed that the glow curves of the nanomaterial exposed to these ions are similar to that exposed to gamma rays, with a dosimetric peak at 462 K beside a smaller one at 503 K, while those of the microcrystalline sample exposed to both ion beams and gamma rays have their prominent peak at 503 K beside a smaller one at 462 K. The observed TL sensitivity of the nanocrystalline material is less than that of the microcrystalline sample at low fluences/doses, while it is more at higher fluences/doses. This nanophosphor exhibits a linear/sublinear TL response to energetic ions and gamma radiation over a very wide range of exposures, which is much wider compared to that of its microcrystalline counterpart. This makes the nanostructural form of BaSO4:Eu useful to estimate the high doses of different ionising radiations that are in use for radiotherapy or food/seed irradiation.
用48 MeV的7Li3+、75 MeV的C6+和90 MeV的O7+离子束在1 ~ 109 ~ 1 ~ 1013个离子/cm2的影响范围内照射了粒径约为40 nm的BaSO4:Eu荧光粉纳米粒子。记录并研究了辐照样品的热释光曲线。该样品的微晶形式包括在研究中,目的是报告比较测量。该材料在其纳米和微观形式暴露于60Co的伽马射线的TL结果也包括和更详细地研究。结果表明,纳米材料在离子作用下的发光曲线与伽玛射线作用下的发光曲线相似,在462 K处有一个剂量峰,旁边有一个较小的剂量峰,而在离子束和伽玛射线作用下的微晶样品在503 K处有一个明显的剂量峰,旁边有一个较小的剂量峰。观察到纳米晶材料在低通量/剂量下的TL灵敏度低于微晶样品,而在高通量/剂量下则高于微晶样品。这种纳米荧光粉在很宽的暴露范围内对高能离子和伽马辐射表现出线性/亚线性的TL响应,与微晶荧光粉相比,这种响应要宽得多。这使得BaSO4:Eu的纳米结构形式有助于估计用于放射治疗或食物/种子辐照的不同电离辐射的高剂量。

Chloride-induced reinforcement corrosion is the principal cause of deterioration of concrete structures in the Arabian Gulf and the world over. Preventive measures against corrosion require maintaining the chloride and sulphate concentration in concrete below the threshold limits specified by the standards. This requires monitoring the chloride and sulphate concentration in concrete, and a nondestructive technique is preferable for this purpose. The Prompt-Gamma Neutron Activation Analysis (PGNAA) technique can be used to monitor the concentration of corrosive elements in concrete specimens. An accelerator-based PGNAA setup has been developed to measure the chloride and sulphate concentration in concrete. The PGNAA technique has been utilised successfully to measure the elemental composition of concrete. In this regard, several studies were undertaken to determine the calcium, silicon, chloride and sulphate concentration in the concrete specimens. Furthermore, the concentration of compounds, such as lime and silica was also determined. The results of these studies along with a description of the facility are presented in this paper.
氯化物引起的钢筋腐蚀是阿拉伯湾和世界各地混凝土结构恶化的主要原因。防止腐蚀的措施要求将混凝土中的氯化物和硫酸盐浓度保持在标准规定的阈值范围以下。这就需要监测混凝土中的氯化物和硫酸盐浓度,而非破坏性技术是实现这一目的的首选方法。快速中子活化分析(PGNAA)技术可用于监测混凝土试样中腐蚀元素的浓度。研制了一种基于加速剂的PGNAA装置,用于测量混凝土中氯化物和硫酸盐的浓度。PGNAA技术已成功地用于测量混凝土的元素组成。在这方面,进行了几项研究,以确定混凝土样品中的钙、硅、氯化物和硫酸盐浓度。此外,还测定了石灰和二氧化硅等化合物的浓度。本文介绍了这些研究的结果以及对该设施的描述。

Global nuclear crisis 全球核危机
Pub Date : 2010-02-08 DOI: 10.1504/AFP.2010.031497
M. Shekhar
We are living in a world rife with many types of crises. The most prominent and urgent crisis involves the Earth's ecology. Environmental crises involving ozone depletion, global warming, toxic and radioactive wastes, air pollution, industrial accidents, etc., are affecting communities around the world. This paper examines changes in crisis management theory and practice. In the past two decades, much progress has been made in our understanding of industrial and environmental crises. However, our understanding remains highly fragmented and selective. We need to integrate diverse findings and cumulatively build on past knowledge. To do this, the concept of sustainable development provides a unifying motif. Some research questions that deserve urgent attention are identified in this paper.
我们生活在一个充满各种危机的世界。最突出和最紧迫的危机涉及地球生态。涉及臭氧消耗、全球变暖、有毒和放射性废物、空气污染、工业事故等的环境危机正在影响世界各地的社区。本文考察了危机管理理论和实践的变化。在过去的二十年里,我们对工业和环境危机的理解取得了很大的进步。然而,我们的理解仍然是高度分散和选择性的。我们需要整合不同的发现,并在过去知识的基础上不断积累。为此,可持续发展的概念提供了一个统一的主题。本文指出了一些亟待关注的研究问题。

The most prominent and urgent crisis involves the Earth's ecology. Environmental crises involving ozone depletion, global warming, toxic and radioactive wastes, air pollution, industrial accidents, etc., are affecting communities around the world. This paper examines changes in crisis management theory and practice. In the past two decades, much progress has been made in our understanding of industrial and environmental crises. However, our understanding remains highly fragmented and selective. We need to integrate diverse findings and cumulatively build on past knowledge.
