This article attempts to clarify some of the central questions and distinctions that provide the necessary backdrop for thinking in a sophisticated way about security in Africa. Drawing on the developing Critical Security Studies literature it suggests that an understanding of security based on people, justice and change offers the surest route to a stable future. It then sketches preliminary answers to some fundamental questions, namely: whose security should be prioritized? How have security dynamics in Africa been influenced by the wider processes driving world politics? What clusters of threats are the most salient? Where do such threats have the most pernicious effects? Which actors are best placed to alleviate those threats? And what sort of institutions should be built to assist in that process? The role of outsiders concerned with promoting security on the continent should be to try to ensure that as many Africans as possible are able to voice their opinions on these crucial issues.  相似文献

The attack on the Westgate Mall in Nairobi, Kenya, in September 2013 intensified international scrutiny of the war against Harakat Al‐Shabaab Mujahideen (Movement of the Warrior Youth). This article analyses the current state of affairs with reference to the three principal sets of actors in this war: Al‐Shabaab, the African Union Mission in Somalia (AMISOM) and its international partners, and the various actors currently involved in building the Somali Federal Government's security forces. It argues that although the newly reconfigured Al‐Shabaab poses a major tactical threat in Somalia and across the wider Horn of Africa, the movement is becoming a less important actor in Somalia's national politics. As Al‐Shabaab loses territory and its popularity among Somalis continues to dwindle, other clan‐ and region‐based actors will become more salient as national debates over federalism, the decentralization of governance mechanisms beyond Mogadishu and the place of clannism will occupy centre stage. As a consequence, AMISOM's principal roles should gradually shift from degrading Al‐Shabaab towards a broader stabilization agenda: encouraging a national consensus over how to build effective governance structures; developing an effective set of Somali National Security Forces; and ensuring that the Federal Government delivers services and effective governance to its citizens, especially beyond Mogadishu in the settlements recently captured from Al‐Shabaab. As it stands, however, AMISOM is not prepared to carry out these activities. More worryingly, nor is the Somali Federal Government.  相似文献

Within trafficking discourses, men appear as predatory and exploitative, while boys appear as victims. This flattens the complexities of social life and obscures the ways that constructs of masculinity frame the trajectories of labour migrants and their brokers. This article challenges those discourses, drawing on research with two groups of labour migrants characterized as ‘victims of trafficking’, as well as with ‘traffickers’ who help them to move and work. The first are adolescents moving from Benin to the gravel quarries of Abeokuta, Nigeria. The second are adults from across West Africa who have made the illegal journey to Italy, where they live in ‘ghettos’ and work as gang labourers on harvests. In each case, migrants and their brokers come from the same or similar communities; (shared) ideals of masculinity structure their mobility and labour. Gendered transitions towards adulthood, the pressure to attain riches and status and a duty of responsibility to those younger and less successful are important. A focus on their masculinities takes us beyond ‘victim-perpetrator’ dyads.  相似文献

Agrégation played a key role in the operation of the Université de France of the nineteenth century but is poorly understood in the English-speaking world. Characteristics of the French Université are outlined, and the agrégation competition of 1866 in which Vidal de la Blache participated is described in detail, as further illustration of the early training and intellectual orientation of the future founder of the French school of human geography. Characteristics of the successful candidates in the agrégation examinations are then examined, and possible reasons for the perennial shortage of agrégés teaching in the Université are suggested .
Alors que l'agrégation était une force majeure pour le fonctionnement de l'Université de France au xixmesiècte elte n'est que faiblement comprise au delà du monde français. Dans cet article, j'expose quelques traits principaux de l'Université française et j'explique en détail le concours d'agrégation de 1866, dans lequel Vidal de la Blache a concouru, pour illustrer cette étape importante dans la formation intellectuelle et professionnelle du future fondateur de I'Ecole française de la Géographic humaine. Puts, j'examine les caratéristiques des concurrents reçus à l'agrégation et j'avance quelques raisons possibles pour expliquer le deficit continuel d'agrégés dans les postes enseignants de l'Université, durant le XIXme siècle .  相似文献
