Efforts at winning hearts and minds (WHAM) impact on and are affected by perceptions of legitimacy. In the Namibian war for independence (1966–1989) efforts of the South African counterinsurgent forces at winning hearts and minds focused mainly on persuading the population to cooperate in exchange for material benefits and services. The article demonstrates that this successfully contributed to a dimension of legitimacy that is conceptualized as pragmatic legitimacy. However, other dimensions of legitimacy are identified in which the South Africans were lacking, that is in moral, legal, and identity-based legitimacy. Furthermore, in areas where control was contested and where the population could not be shielded from insurgent intimidation, it is argued that the effects of coercion outweighed legitimacy altogether.  相似文献

“There is nothing more difficult to carry out, nor more doubtful of success, nor more dangerous to handle than to initiate a new order of things. For the reformer has enemies in all who profit by the old order, and only lukewarm defenders in all those who would profit by the new order”—Machiavelli

This essay was written after a team of the Institute for Security Studies visited the Democratic Republic of the Congo (DRC) to share their experiences of the challenges of defence transformation with Congolese officials and members of civil society.

It discusses the South African defence transformation process and experience in detail and highlights the imperative for visionary leadership, commitment and communication as prerequisites for successful transformation. The DRC faces a unique opportunity to design and create an optimal national defence force for itself, which will reflect its new and evolving national policy on defence, and therefore the needs of the nation. This poses an exciting challenge and true opportunity to move beyond survival into a new age. The essay aims to make a contribution to this process.  相似文献

Recently, in July 2012, the high-profile and bitterly fought nine-month race for the post of Chair of the African Union (AU) Commission, between Dr Jean Ping of Gabon, and his main challenger, Dr Nkosazana Dlamini-Zuma, culminated in the latter's victory. Her victory came after the deadlock at the Eighteenth AU Summit in January 2012. Borne out of the considered need for a quick fix through reliance on a vote of expediency, the election of Dr Dlamini-Zuma represented a political resolution to the crisis that arose due to the earlier ongoing electoral deadlock. Far from being a competitive election by design, the 2012 AU Commission election by default became transformed into an intensely fought campaign that put the AU in the limelight. This article briefly introduces the electoral process, explains in detail the voting behaviour of AU member states, and offers five specific reasons for the victory of Dr Dlamini-Zuma. On the surface the election looks very competitive, but the article explains why this is not the case. To create greater competition for these posts, the AU needs to overhaul the nomination process and the voting procedure. In this regard, the article proffers detailed analysis and proposes a radical revision of the existing criteria for the nomination. The article also proposes specific recommendations for the amendment of the rules of procedure of the AU Assembly to allow for a qualified majority as a deadlock breaker in the fifth round. It also assesses whether the integrity of the AU Commission election was damaged during the campaigning and voting process. In this regard, it recommends the development of a code of conduct for future elections at the AU.  相似文献

摘 要:由于舰载火箭弹的弹道特性与普通身管炮弹有着明显的差异,传统的舰炮射击效力计算及火力分配方法不适用于舰载火箭炮。结合舰载火箭弹弹道特点,分析了其射击误差,探讨了集群目标的简化处理方法,提出了一种基于蒙特卡洛法的舰载火箭炮对岸射击最优效力射火力分配计算模型。通过举例分析表明,该方法切实可行,利用该模型可以提高射击指挥员指挥决策的科学性。  相似文献

针对无人机作战中前置追踪占位法存在导弹发射条件苛刻且目标机动时成功率锐减和离散对策占位法应用局限性较大等问题,提出一种无人作战飞机近距对抗占位策略与导引方法。该占位策略为解算无人机近距对抗占位的伪跟踪点,并设计一种三维变结构导引律,引导无人机完成近距作战占位机动。仿真结果表明,该占位策略与导引方法快速有效,满足无人机近距对抗时的战术指标要求。  相似文献

This essay provides an overview of the eras of Mexican cinema followed by an analysis of 10 Spanish-language narco cinematic representations, an overview of the eras of American cinema followed by an analysis of 10 English language narco cinematic representations, and a conclusion that compares and contrasts the Mexican and US narco war cinematic experience. Due to divergent national trajectories – Mexico is engulfed in narco violence and corruption while the United States is not – more differences than similarities exist between these national cinematic genres. Dark spirituality themes are also increasingly evident in more recent narco war films.  相似文献

In this article, we present a multistage model to optimize inventory control decisions under stochastic demand and continuous review. We first formulate the general problem for continuous stages and use a decomposition solution approach: since it is never optimal to let orders cross, the general problem can be broken into a set of single‐unit subproblems that can be solved in a sequential fashion. These subproblems are optimal control problems for which a differential equation must be solved. This can be done easily by recursively identifying coefficients and performing a line search. The methodology is then extended to a discrete number of stages and allows us to compute the optimal solution in an efficient manner, with a competitive complexity. © 2016 Wiley Periodicals, Inc.

ABSTRACT

With the world’s ninth largest economy and comprising nearly 60% of South America’s GDP, 47% of its territory, and 49% of its population, Brazil has become a regional power and an important actor in world affairs over recent decades. This scenario has led the government to re-evaluate its role in the world order, resulting in the enactment of the National Defence Policy, whose objective was to consolidate the country as a regional power while at the same time addressing national security issues, promoting economic development through a series of defence programmes, restructuring the defence industrial base, fostering innovation through technology and knowledge transfer to Brazil, and indigenous research and development. However, the policy’s implementation suffers from several challenges discussed in this article, which may test the capability and competence of Brazilian policymakers, military, industrialists, and other individuals and organisations involved in its implementation.  相似文献

The interpretation of self-determination as a vote for secession shaped the state that South Sudan has become since the 2011 referendum. Self-determination, this paper argues, is a democratic political process in which citizens determine their preferred form of statehood and nature of governance for their country. In South Sudan, however, political actors—with international support—established conditions that reduced such complex democratic processes to narrow technical matters. Equating self-determination with secession consolidated political and military domination in a process designed to end such domination. This was done at the expense of a more inclusive, process-oriented and political interpretation of self-determination.  相似文献
