“None of the Kings on Earth is Their Equal in ʿaṣabiyya”: The Mongols in Ibn Khaldūn's Works

The rise of the Mongol empire was a shock to the Arab world and led many Arab authors to describe these conquerors in decidedly negative terms. The great historian Ibn Khaldūn also discusses the Mongols' rise and their conquests. As a nomadic people they challenged and defeated sedentary populations and founded their own dynasties. Consequently, the Mongol conquests perfectly fit Ibn Khaldūn's theories on ?a?abiyya – which is superior in nomadic groups – and the rise and fall of dynasties. For the Maghrebi historian, the rise of the Mongols was a natural step in the course of history. This consequently colours his view of the Mongols and affects the way he portrays them, especially regarding the themes of violence and religion – recurring themes in many contemporary works dealing with the Mongols – and in his depiction of the Turco-Mongolian conqueror Timur, who is presented in a more favourable light by Ibn Khaldūn than he is in many contemporary works.     

Kinship,Camaraderie and Contestation: Fāṭimid Relations with the Ashrāf in the Fourth/Tenth Century.

The founding of the Fā?imid caliphate across the southern Mediterranean, and then in Egypt, Syria and the ?ijāz at the turn of the fourth/tenth century, necessitated its negotiation with the ashrāf, those who claimed lineal descent from the Prophet Mu?ammad, and who by this time had gained significant influence as a social class based on their charismatic descent. While other dynastic powers fostered relationships with various members of the ashrāf, the Fā?imid–ashrāf dynamics were distinctive in that the Fā?imids legitimised their rule as Ismā?īlī Shī?ī imām-caliphs, based on their claim of descent from the Prophet Mu?ammad, and as the sole successors to his authority and leadership over the Islamic world. Consequently, Fā?imid–ashrāf relations were permeated by fraternal camaraderie as well as by competing contestations based on their shared claim to Prophetic lineage.

反思与争鸣：缔造中国武术的生存空间

文章采用文献资料法、逻辑分析法,运用文化学、历史学等相关理论,以中国武术为研究对象,从民族文化视角来研究中国武术的发展问题。中国武术作为民族文化的一种符号和身份象征,要走出“文化失语”的困惑,要敢于同历史对话、同现实对话、同自己对话。要调整自己的文化立场,开拓属于自身的生存空间,最终也守护着民族文化的大空间,延续着民族的文明进程。

The Philosophical Conflict between the School of Baghdad and the School of Khorasan in the Tenth Century: Towards a New Understanding of the Development of Islamic Philosophy

Historians often present the evolution of Islamic philosophy through a limited number of philosophers beginning with al-Kindī and concluding with Ibn Rushd. This practice tacitly asserts that Islamic philosophy developed only in accordance with this “sequential” or “chronological” context that assumes it was the inevitable evolution of Aristotelian thought in Arabic. However, most of those who present Islamic philosophy in this manner appear to have overlooked the fact that it developed in the context of a philosophical conflict that emerged between the two schools to which the majority of Islamic philosophers belonged – the School of Baghdad and the School of Khorasan, which appeared in the tenth century and introduced philosophy to Islam and Muslims. This study stands apart from earlier attempts to present Islamic philosophy by considering these two schools and the frequently violent disputes that occurred between them. It is based on an historical-analytical approach accompanied by a rereading of numerous historical and literary texts and presents a reinterpretation of the works of Ibn Sīnā that differs from past interpretations of the history of Islamic philosophy. The study concludes with a thorough examination of the texts and contexts, which demonstrates the existence of the two philosophical schools and their significant contributions to the development of Islamic philosophy, albeit with their own distinctive elements. The study also argues that the philosophical School of Baghdad migrated to Morocco and Andalusia and arrived, in some respects, in Europe through Ibn Rushd, whereas the School of Khorasan appeared in Suhrawardī’s Philosophy of Illumination and in modern Iranian philosophy.     

城市化进程中的中国体育现状研究

摘要：城市化是国家经济制度、政治体制和社会形态发生变革的重要引擎,在体育领域,城市化进程的结束则标志着体育发展方式的重要转型。有鉴于此,以我国城市化进程中的体育发展现状为研究对象,主要采用文献资料法和比较分析法,结合英、美2国的实例,详细梳理城市化进程结束后,即城市化水平达到50%背景下,城市化对我国体育人口规模、体育空间布局、体育产业结构以及体育管理体制所造成的影响,其研究结果对于厘清现阶段我国体育发展的症结及未来我国体育改革的对策均具有重要的理论意义及实践价值。研究认为：城市化作为一种人类社会发展的普遍规律,始终影响着体育发展的进程与走向;城市化水平与体育发展的现实水平存在着高度的相关性,当城市化水平达到50%的时候,标志着体育将进入到一个全面转型的发展时期;我国已经进入到城市化进程过半的关键时期,城市化对体育发展方式的影响已经全方位体现出来,城市化引致的人口聚集成为了体育人口发展的基础,城市化引发的城市扩张导致了体育空间布局的整合,城市化催生的结构调整搭建了体育产业发展的平台,城市化激发的制度改革完善了管理体制发展的模式。     

基于对应分析模型原理的户外运动安全风险研究

通过对我国2001年至2014年期间,258个户外运动安全事故案例的统计和分析,结合国内外相关研究,建立户外运动安全风险分析框架,将户外运动安全风险划分为4个维度,18个因素指标.根据对应分析模型原理,深入研究户外运动中季节、月份与时段风险的对应性关系,R(3.2.0)软件运行结果显示:户外运动中,凌晨和晚上的风险指数最高;春季、秋季的上午和下午时段,可能存在的伤亡风险几率较高;5月、9月、10月的上午和晚上,3月、6月、11月、12月的下午,1月和4月的凌晨时段,可能存在的伤亡风险几率更高.使用Minitab软件,根据累积贡献率80％以上为主要因素的帕累托原则得到8个主要风险因素和7个次要风险因素.     

中国地域武术研究的现实困境及突破*

采用文献资料法、逻辑分析法等,在简要回顾研究进展的基础上,得出地域武术面临着地域数量“有限性”、空间边界“稳定性”、文本表达趋同性、研究方法滞后性等现实困境,造成了对地域武术浅层叙事和诸多曲解现状.突破现实困境需要我们具有地域空间重绘、地域纵向横向比较、交叉学科成果借鉴、多元方法引入等综合意识,形成动态地域武术观.
