South Africa's threat environment: a guide for the National Planning Commission

Abstract

The mandate of South Africa's recently appointed National Planning Commission includes addressing ‘defence and security matters’. This article seeks to outline the central elements of the threat environment facing South Africa in the foreseeable future. It is argued that South Africa faces no meaningful existential threat from conventional military forces but that its security forces will need to be prepared to address possible raids and attacks by conventional military forces both on home soil and on vital interests beyond the nation's borders. Other threats highlighted include the threats posed by potential insurgencies, by terrorism, and by crime, social unrest and banditry. Also addressed is the danger of so-called hybrid threats, in which two or more of the single threat types outlined here are combined. Finally, the article challenges the National Planning Commission to rethink South Africa's policy on peace operations in the light of the need to ensure the safety and security of the nation's citizenry.     

基于非负矩阵分解的电磁超声系统优化研究

针对孤立脉冲群电磁超声系统信号特征容易被噪声淹没的问题,提出基于改进的非负矩阵分解（INMF）优选特征的支持向量机（SVM）方法．首先,用3种不同的方法提取高维特征;其次,用NMF方法实现特征降维,并保证降维结果的唯一性,避免对特征的直接选择;最后,应用支持向量机方法对降维特征进行分类．对孤立脉冲群电磁超声系统采集的4种信号特征进行提取、选择和分类,实验结果表明：INMF方法能有效提取微弱信号的特征,减少运算量,提高电磁超声系统特征采集的准确率．

When the green gets greener: political Islam's newly-found environmentalism

Although the environmental movement was established in the West, there is currently an Islamist variant that has received less attention. The Quran and the Hadiths provide guidance for the faithful on the relationship between Allah, humanity and nature. The article will examine and compare the environmental agendas of six Islamist groups: Hizb'allah, Hizb ut-Tahrir, Hamas, the Muslim Brotherhood, Jamaat-e-Islami, and al Qaeda. While they all share similar concerns, Islamists have developed globalized, glocalized, or localized ‘scales’ of engagement, depending on the targeted audience. Finally, the article will examine the security implications of Islamist environmentalism, including the possibility of an alliance between Islamists and militant environmentalists.
