‘Fighting for peace’

In Africa, most of the present conflicts are civil, intra-state wars where belligerent groups use guerrilla tactics to achieve various political, economic or ideological objectives. The atrocities and the effect of these on-going wars on innocent civilians, human suffering, poverty and development are beyond comprehension. Not surprisingly, the majority of current peace operations are in Africa, with more than 70 countries contributing forces to these conflict zones. On the continent, South Africa has come to assume a leading role in peace operations and is now a major troop-contributing country to UN and AU missions. In the past 11 years, the South African National Defence Force (SANDF) has taken part in no fewer than 14 peace missions. This article provides a brief background of the conflicts in Burundi, the Democratic Republic of Congo (DRC) and Sudan, the different United Nations (UN) and African Union (AU) mandates under which peacekeepers had to operate as well as their objectives, and the extent of South Africa's involvement in the various missions. In the last section, the major challenges, that these operations have posed are highlighted.     

SECURITY GOVERNANCE IN SOUTH AFRICA

In the ten years since the establishment of South Africa's first inclusive democratic government, an ambitious, extensive and systematic process of reform has been carried out in the governance of security. The process is widely regarded as having been successful and a model for other processes of ‘security sector reform’ in the context of transitions from authoritarian forms of governance to democratic ones.

That this been achieved with hardly a shot fired in anger is a remarkable achievement and a credit to visionary political leadership as well as organisational capacity, in other words to effective security governance.

At the same time, progress has been uneven and sometimes fragmentary, policy intentions and commitments have not always been translated into practice, the end results have not been to everyone's liking, and transformation has engendered its own pathologies. Thus several challenges remain in improving security governance.

This article provides a broad overview of the roles played by the various actors in the governance of the security sector, including the executive, parliament and civil society. It examines the main policy frameworks and touches on organisational transformation, because it is impossible to deal with governance in isolation from these issues. Policy processes and the frameworks they give rise to—in particular—are critical for effective governance. This article deals with the defence, safety and security and intelligence fields. A comprehensive overview would need to include the governance of criminal justice and foreign policy. The article does not seek to make an overall evaluation of governance, but to identify achievements, shortfalls and challenges.

刑事法律制度差异对海峡两岸合作打击跨境犯罪的影响及对策研究

大陆地区和台湾地区的刑事法律制度存在较大差异,必将影响海峡两岸共同合作打击跨境犯罪工作的开展。海峡两岸应在《海峡两岸共同打击犯罪及司法互助协议》框架下,在协商互信的基础上,本着对两岸刑事法律制度差异的清晰认识,采取合理、有效的刑事对策弱化其对两岸合作打击跨境犯罪的影响。

语文教师在中学作文教学中“导”的作用

中学作文教学是整个语文教学中十分重要的一环,传统的作文教学方法忽视学生的主体作用,而"写前-写中-写后"三阶段作文教学法突出了语文教师应有的"引导"作用,在作文教学中侧重对学生主体性的调动,让作文教学在语文教师"导"的作用下更好地成为教与学的互动平台,进一步提高学生的写作能力。     

天然气在土壤中泄漏的稳态温度场分析

埋地高压天然气经小孔泄漏会导致土壤冻结形成冻土,应用一元气体动力学、流体力学和传热学知识建立了天然气小孔泄漏吸热率模型和土壤稳态温度场模型,并进行了实例计算。结果表明：当天然气输送压力小于临界压力,小孔泄漏吸热率随压力的增大而增大;当天然气输送压力大于等于临界压力,小孔泄漏吸热率达到最大值;冻土厚度随土壤热导率或空气对流传热系数的增大而减小,但土壤热导率对其影响较小,空气对流传热系数对其影响较大。
