Mobility in pastoral societies of Northern Mali: Perspectives on social and political rationales

Since the 1980s, the so-called “nomadic” populations in the regions of Northern Mali and Niger have embarked on an extensive process of settlement. Today they mostly live in villages or “settlement sites”. But, at the same time, individuals and small groups among these same populations have considerably enlarged their area of mobility and accelerated the rate and the value of the trade in which they engage. These two phenomena could, at first sight, appear contradictory. But the observation of empirical situations shows, rather, compatibilities, similarities even, between these two concomitant phenomena. Building on innovative debates conducted in geography and sociology, this article puts forward the hypothesis that the building of villages, as well as integration into military bases and barracks, proceeds from (social) rationales of mobility, just as much as transhumance, journeys, migration. Much more than a simple displacement in space, the notion of mobility could describe an “art of doing”, a way of being to others and to the world.     

Trading in development: norms and institutions in the making/unmaking of European Union–African,Caribbean and Pacific trade and development cooperation

This paper offers a contribution to recent debates on European Union (EU) external trade and development policy, with a specific focus on the African, Caribbean and Pacific (ACP) group of countries. The question asked is why the EU encountered such difficulties in the attempt to translate its normative preferences for freer trade and closer economic integration into a series of binding agreements? Drawing on both economic constructivist and historical institutionalist insights, it is argued that the case for reform initially rested on a strong convergence between institutions and ideas, enabling the EU to discursively present desired policy reforms as necessary to satisfy World Trade Organisation trade rules. However, in due course, the institutional dynamics behind the latter began to diverge from the EU's policy preferences and blunt its norm-based argument – thus creating the space for transnational coalitions to, first, question and, ultimately, undermine aspects the EU's trade and development prospectus for the ACP.     

Corruption and identity politics in divided societies

Corruption is a major problem for populations in various parts of the world. This article argues that to understand the problems and dynamics of corruption, we need to understand how discourses and practices of corruption (and anti-corruption efforts) are intertwined with the construction and contestations of identity. Identity politics is a salient feature in peaceful political struggles, as well as in contemporary armed conflicts, which are often characterised by the politicisation of collective identity (ethnic, national, religious) for the violent pursuit of power. The article outlines and discusses four ways in which identity politics and corruption intersect. First, it points to the often blurred lines between private and collective benefit from corruption, revealing the implications of group identity for how corruption is conceptualised. Second, it shows how corruption may exacerbate grievances along identity lines. Third, it highlights how corruption can be used strategically in identity-based conflicts. Finally, it explores how corruption may encourage cross-ethnic solidarity and mobilisation that defy conflict divides.     

“Use words. Not your body”: The hunger that has no name

This essay examines the competing readings of food refusal that emerged from a student hunger strike held at Columbia University in fall 2007. The invisibility of the act of food refusal forces hunger strikers to adopt performance strategies that make their (non)action visible as protest. To make the politics of their food refusal legible, advocates for the hunger strike promoted their actions as part of a 40 year tradition of student protest. However, that same invisibility allowed the protest's detractors to deride the hunger strikers as anorexic. At the center of the protest and the commentary about it was a wasting female body that confused for spectators the line between the political and the pathological. Attention to this body raises questions of how community is created and disciplined through performative acts, how easily female protest is evacuated of political meaning and the uneasy role of whiteness in popular attention to anorexia.     

“星链”军事化发展及其对全球战略稳定性的影响

美国推进“星链”军事化发展,使得外空安全和全球战略稳定面临严峻挑战,必须对其潜在风险进行提前研判和评估。较之传统外空装备,“星链”具有多维一体的战场网络覆盖能力、延伸全杀伤链的集成性功能以及面向实战化的信息作战优势,将对全球战略稳定格局带来三大冲击：一是冲击首攻稳定性,“星链”既强化了美国先发制人的战略突袭能力,又弥补了军用太空资产固有的脆弱性,提升了美国太空攻防的整体能力;二是冲击危机稳定性,“星链”会加剧外层空间爆发“意外战争”的风险,同时,针对“星链”的制衡与反制措施可能造成外空危机的快速升级,并由战略领域向常规领域扩散;三是冲击军备竞赛稳定性,“星链”具有攻防一体和军民两用属性,可能加剧军备发展的“安全困境”,引发技术扩散和军备竞赛风险。“星链”技术系统的不透明性和不可预测性,导致有关军备控制的信心建立措施难以施行。应对“星链”军事化发展对于全球战略稳定的挑战,必须吸纳涵盖商业部门在内的多元化安全治理主体,构建核、外空、网络和人工智能等多域联动的安全治理机制,推动面向未来的可持续安全治理。     

GC/ECD检验生物检材中的氟乙酸钠

建立对生物检材中氟乙酸钠的GC/ECD检验方法。用PFBBr作衍生化试剂,对氟乙酸钠或氟乙酰胺中毒后脏器中的氯乙酸（氯乙酸钠）进行衍生化,GC/ECD和GC／MS的分析。在1ml血中添加lμg1080,其回收率为76．2％,RSD为3．07（n＝7）;在1g肝中添加2μg的1080其回收率为84．4％,RSD为1．87（n=5）。研究的方法经动物试验和大量中毒案件的验证,效果较好。该方法已在中毒案件的检验中广泛应用。     

《鹿特丹规则》下无单放货解决机制：从凭保函放货到凭指示放货

《鹿特丹规则》对无单放货问题设计了新的解决机制，通过使特定条件下的无单放货合法化，试图减轻承运人的负担，平衡船货双方的利益。采取规范分析的方法，对这一机制进行解构，论述其给各当事方的法律地位所带来的变化，认为对现有制度进行改良可能是更好的选择。
