Abd el-Krim's guerrilla war against Spain and France in North Africa: An adventure setting for screen melodramas

The Riffian rebel leader Mohammed Abd el-Krim Al-Khattabi (1882–1963) became an important early guerrilla leader by successfully initiating extensively organized resistance in the Moroccan Rif against Spanish and French imperial power in the early 1920s. The Rif War triggered a wave of adventure films since the 1930s. This article will look at some of these, especially Sergeant Klems (1971) and The Wind and the Lion (1975), and suggest that they can be seen in terms of the wider impact of screen Orientalism derived from the iconic film Lawrence of Arabia (1962) directed by David Lean. The article will show that these films promoted what it terms a colonial gaze by underlining many stereotyped cinematic clichés relating to the Islamic cultural area and Abd el-Krim's revolt that stretch back to the early history of cinema.

幼教专业学生幼儿性教育知识结构现状与建议——基于福建省一所学校的调查

幼儿性教育是成年后性心理教育的基础。采用问卷调查法对幼高专幼教专业学生幼儿性教育本体性知识和实践性知识进行了现状调查,调查显示幼高专幼教专业学生所掌握的与幼儿性教育有关的本体性知识不全面、实践知识也不合理;同时,学生本体性知识的缺乏又使得幼儿性教育难于实施。在此基础上,本文提出发展学生幼儿性教育知识结构的途径:幼儿性教育课程化;重视以学生为主体的性教育教学实践,引导学生主动建构幼儿性教育知识结构。     

解析“翻转课堂”中的教师角色

翻转课堂颠覆了传统的教学模式,实现了学生的个性化学习,学生的学习主体性得到了彰显。不过,教师的作用不仅没有弱化,反而变得更加重要,教师在翻转课堂中具有多重角色,是翻转课堂成功实施的关键。本文简要分析和研究教师在翻转课堂中的重要角色。     

New terrorist threat to India's internal security: the danger from Pakistan's “Karachi Project”

The spectacular commando-style terrorist strike on Mumbai in November 2008 exposed India's lax internal security structure. As nearly all the security apparatus broke down during the long spell of attacks, massive public outrage flared up across the country calling for a firmer government response. Shockingly, India has done little to prevent a recurrence and a new security threat faces the country every single day not merely before but even after the Mumbai attacks. In contrast, Pakistan's Inter Services Intelligence and the Lashkar-e-Taiba have successfully evaded pressures from both India and the international community and continue their terror campaign against India under the “Karachi Project” with the explicit intention to unsettle South Asia. Classified documents indicated that India is at the forefront of a cataclysmic “nuclear terrorism” threat from a “combination of Pakistan-based terrorists and homegrown radicals.” This article analyses the danger posed by the Indo-Pak radical groups targeting India and India's lack of preparedness to the new security threat from the “Karachi Project.”     

Explaining the (il)legality of Uganda's intervention in the current South Sudan conflict

During the night of 15 December 2013, fighting broke out between factions of the Sudan People's Liberation Army (SPLA) in Juba, the capital of the Republic of South Sudan. The fighting pitted forces loyal to President Salva Kiir against those loyal to former Vice President Riek Machar. Five days later, Uganda sent troops into South Sudan, advancing a number of reasons for intervention, including that it had been invited by the legitimate government of South Sudan to ensure order; it needed to evacuate Ugandan citizens caught up in the fighting; it had been asked by the United Nations Secretary-General to intervene; and that the regional organisation, the Intergovernmental Authority on Development had sanctioned the intervention. As the conflict escalated, Ugandan troops started fighting on the side of forces loyal to Kiir. The underlying reasons for the intervention were clearly economic, but those advanced were legal. This article discusses both sets of reasons and concludes that the economic reasons are more persuasive. Nevertheless, while some of the legal arguments (such as being invited by the legitimate government of South Sudan) can be asserted, others are clearly dubious. In addition, the participation of Ugandan troops in the fighting on the side of the Kiir government renders the intervention illegal.     

军队士气研究中应澄清的几个问题

对士气内涵的揭示,一直是个见仁见智的问题。对军队士气的研究应当从外延着手分析,确定真正符合士气本质属性的取舍标准。文章着重澄清以下几个问题:是士气的影响因素还是士气本身;士气能否被科学地测量;士气是否具有跨情境的稳定性;士气能否对战斗力构成影响。     

空间碎片碰撞预警系统设计

为评估航天遭遇空间碎片碰撞的概率,设计了空间碎片碰撞预警系统的总体结构,建立了空间碎片数据库。针对航天器和空间碎片最接近时刻的确定及航天器位置误差协方差矩阵计算问题,基于成熟的SGP4和HPOP程序模块,提出了一种新的工程实现方法。在分析现有碰撞概率计算方法的基础上,先利用多种筛选方法剔除无威胁碎片以提高计算速度,再精确计算碰撞概率。充分利用现有程序集,结合多种编程技术,缩短了系统开发周期,并实现了系统的可视化。
