Regional responses to security and development challenges in East and Southern Africa: lessons and way forward

Since the mid-twentieth century, the East and Southern African regions have been mired in complex and overlapping security and development challenges, including ethnopolitical conflicts, terrorist insurgencies, the proliferation of small arms and light weapons (SALWs), and overwhelming economic crisis. These challenges have had implications for human security, socio-economic development, territorial authority, sovereignty and the stability and legitimacy of political regimes in the affected states. The adequacy and relevance of the regional responses to these challenges is the subject of ongoing debate, to which this paper now adds. Among other factors, this paper identifies competition for regional dominance and institutional inadequacies as accounting for the inability of regional governance bodies to respond adequately to the challenges they face. Consequently, it recommends the expansion of the mandate of the Regional Economic Communities (RECs) beyond regional economic integration to include peacebuilding and a deepening of the institutional efforts focused on security cooperation and conflict management.

一种增强嵌入式系统安全性的安全防护技术*

由于嵌入式应用环境的多样性,单纯软件或硬件安全技术或者安全产品的功能和性能都有其局限性,只能满足某类系统的特定安全需求。因此,如何有效利用软硬件技术特点,通过协同防护来保障系统的安全已成为当前信息安全领域的研究热点。通过对嵌入式系统安全威胁和隐患的分析,在此基础上提出一种可以提高嵌入式系统安全性的软硬协同安全防护技术。该技术通过硬件检测、软件处理、综合治理的方法,可以有效地增强嵌入式系统抗击本身缺陷和恶意攻击的能力。     

基于HLA的电子战仿真测试与评估

The security sector and the plunder of Zimbabwe’s Chiadzwa alluvial diamonds: the ‘goat mentality’ in practice

While the human rights impact of the deployment of state security agencies in the Chiadzwa diamond fields has been explored, it is important to continue to expose the increasing tendency within the sector to take public resources that should be protected by the state and used for the benefit of the people and channel them for personal gain. The security sector stranglehold of President Robert Mugabe and the ruling political party, the Zimbabwe African National Union Patriotic Front (ZANU-PF), has facilitated the siphoning of Chiadzwa diamond revenue into the pockets of individual security personnel. The unfolding sociopolitical crisis in Zimbabwe has also meant that these security personnel have been deployed beyond conflict zones and into traditionally civilian domains, with dire consequences for the public purse. With this in mind, it is asserted that these issues have driven state security agencies to enrich themselves through what is termed in this article as a ‘goat mentality’. The article thus explores the ways in which state security agencies have been deployed and gone on to promote personal enrichment in the Chiadzwa diamond fields.
