ABSTRACT

This paper challenges recent claims that competitive market dynamics incentivize Private Military and Security Companies (PMSCs) to fully commit to providing effective services, thereby reducing the duration of civil war. Our assessment of a most-likely case scenario for this argument – Sierra Leone – reveals four critical problems. First, there is rarely direct competition, even if numerous companies are present. Second, the presence of multiple PMSCs usually represents a collaboration among subsidiaries providing distinct services, often under the same corporate umbrella. Third, data aggregation obfuscates the overlap of PMSC presence, inflating the amount of perceived competition. Finally, we raise concerns regarding how quantitative analyses can conflate conflict intensity with conflict termination.  相似文献

This article explores the convergence between three pillars of influence – feminist security studies, civil society activism and policy decision-making – and its role in the adoption and implementation of United Nations Security Council Resolution (UNSCR) 1325. It argues that these three pillars, individually and collectively, have made important contributions to the debate and action on the gender and security agenda, but that they remain organically disconnected. Their convergence has the potential to achieve path-breaking results in the sphere of gender and security, whilst their divergence makes transformation unattainable. We show the disconnect in the application of UNSCR 1325 in Africa and argue that this is partly the reason why, despite enormous efforts, the gains realised in terms of gender equality in the peace and security arena have been negligible.  相似文献

Madagascar     
Despite a constitution that condemns discrimination, as well as positive efforts by all stakeholders, Madagascar is still far from meeting the desired objectives of the Southern African Development Community (SADC) Protocol on Gender and Development, or any other relevant international instruments and conventions. The establishment of an Organising Technical Committee on security sector reform for Madagascar is a positive development, which will hopefully facilitate an understanding of the multiple facets of gender and security in Madagascar as well as advancing the implementation of the instruments calling for greater female participation in the security sector.  相似文献

Ballistic missile defense (BMD) politics present an interesting evolution in how the USA, especially Congress, has come to think about BMD both as operational reality and as a symbolic policy. The argument here is that BMD's operational reality is increasingly overshadowed by its symbolic aspects. Such a status arose from rapidly changing international and domestic politics. The end result is a situation in which BMD policy in a sense floats above the question of its actual combat effectiveness. Its primary mission in part is sustaining US capacity to remain a global power and support its allies.  相似文献

Islamist extremism as an ideology has seemingly spread in influence in the past few years. The violent Islamist threat may have a singular religious dogma, but that does not mean that it will interact in the same fashion within the various cultures it infests. The Sub-Saharan region is one general context where Islamist extremism is both vividly active and misunderstood. Africa's reaction to: Arabization; the adjustment to post-colonial rule; the perception of secular government institutions; the extent of cultural and religious pluralism; and the local character of Muslim leadership and institutions are all very different from that of the Middle East. Scores of terrorism analysts and even Arab populations only too familiar with the Middle East context superimpose Middle East threats over the Sub-Saharan African cultural landscape. Instead of generalizing the Islamist threats, it might be better to ask why it is that violent Islamist groups have traditionally been challenged to expand their influence in Muslim Sub-Saharan Africa. The underestimated Islamist is using ignorance to its advantage, recruiting through channels unnoticed by its Arab counterparts while creatively catering its message by region.  相似文献

This Critical Comment seeks to situate the United Nations Convention on the Law of the Sea (UNCLOS) within the context of South China Sea (SCS) dispute. Bearing in mind that maritime actions of the main disputants – China, Vietnam, and the Philippines – increasingly “securitise” these long-standing disputes and vice versa, the study examines the concept of a maritime “regime complex.” Whereas efforts have being made to examine UNCLOS and indeed the dispute within the framework of a maritime “regime complex,” the key finding shows that the increased “securitisation” of the disputes makes it difficult to envisage effective engagement of UNCLOS as a resolution mechanism. It will also reveal that China's firmly established expansionist agenda in the SCS region is indicative of Beijing's susceptibility to compromise a diplomatic solution to these long-standing disputes. These discoveries are structured around the knowledge that the spatial relation of the SCS critically espouses not only its geo-strategic significance in terms of natural resources endowment, but also the enduring maritime disputes within the region.  相似文献

The issue that this paper tackles is the assessment of the relative security benefits that Cyprus and Greece derive in the context of their cooperation on defence matters. This form of cooperation, known as the ‘Integrated Defence Space Doctrine’, aims at defending their interests in the Aegean Sea and the broader East Mediterranean theatre. The paper relies heavily on earlier research on this topic, which deals with the Greek–Cypriot alliance facing an arms race against Turkey, and uses a coefficient especially designed to assess the optimal levels of security and the associated defence expenditure of the two allies. A comparison of the relative security coefficient values for the two allies suggests that the security benefit that Greece derives thanks to its alliance with Cyprus exceeds the corresponding Cypriot benefit by far. Given the importance assigned to human resources by this index, in conjunction with the demographic problems of Greece, this conclusion justifies the recent Greek defence policy revision, emphasizing quality, capital equipment and flexibility of forces. This revision aims at satisfying the security requirements of the alliance and the increasing demands of an arms race against Turkey.  相似文献

Guinea-Bissau's transition toward democracy has been violent and disruptive. Despite holding elections and attempts to promote economic and social development, the latest government, under President Yala, is not equipped to bring stability or even a more democratic state. A politicised military, inexperienced opposition and corrupt government officials have contributed to the current poverty and instability. Although unlikely to be deposed by the fragmented opposition, Yala is not secure within his own party and is likely to use his position to weaken his opponents. As a Catholic, Yala has been careful to avoid religious conflict by reassuring Muslim citizens that they will not be marginalised. The economy is precarious and poverty has not been addressed. Guinea-Bissau is dependent on foreign donors for its financial needs. Guinea-Bissau has begun military operations against rebels opposing the Senegalese government and the battles seem likely to continue to cause regional instability. Without external intervention political and economic development looks remote.  相似文献

URBAN FORTRESSES     
One of the consequences of the state's inability to protect the life and property of all its citizens—especially in developing countries—is the formation of private alternatives to crime prevention and control. Gated communities, or enclosed neighbourhoods, are one such popular alternative. This article compares the phenomenon of gated communities in two developing countries: South Africa and Brazil. Both countries are plagued by violent crime and share key human development indicators. The article also explores key issues that have been raised around gated communities in both countries. Gated communities can contribute to spatial fragmentation in urban areas, and reflect increased polarisation, fragmentation and diminished solidarity within society. By excluding other urban residents and people from surrounding neighbourhoods, gated communities can contribute to social exclusion, inhibiting the construction of social networks that form the basis of social and economic activities.  相似文献

The ousting of Dr Goodluck Jonathan marked the first time in Nigerian history that a member of the opposition unseated an incumbent in fair and peaceful elections. The smooth transition of power, uncharacteristic of Nigeria, was hailed by the international community as a victory. However, did Muhammadu Buhari win because Jonathan lost or did Jonathan lose because Buhari won? This article argues that Jonathan's growing unpopularity gave Buhari the win, and that Boko Haram played a major role in the president's sinking support. The 2015 presidential election was thus a win for both democracy and Boko Haram.  相似文献
