篇章逻辑与内容义旨

自古以来,大家都认为一篇辞章,首重其“内容”,而其“形式”是次要的。这虽是正确的看法,却隐藏有相当大的后遗症,即只重“内容”,而忽略了对“形式”之重视与研究。本文有鉴于此,便特别锁定辞章中的“篇章逻辑”与“内容义旨”二者,兼顾理论与实际,进行探讨,辨明它们是“内容的形式”与“内容的内容”的关系,以见两者是彼此依存,不可分割的。

A whitewashed curriculum? The construction of race in contemporary PE curriculum policy

Analyses of curricula in a range of countries show how they tend to reinforce, rather than challenge, popular theories of racism. To date, we know little about the contribution of physical education (PE) curriculum policy to the overall policy landscape. This paper examines the construction of race and racism in two national contexts (Norway and England) as a means of putting race and anti-racism on the PE policy research agenda. It adopts a critical whiteness perspective to analyse how whiteness, as a system of privilege, contributes to the racialisation of valued knowledge in PE and asks, who potentially benefits and/or is marginalised within the learning spaces available in the texts? The discourse analysis reveals that two discursive techniques of whiteness combine to privilege white, Eurocentric knowledge content. Unmarked white PE practices and students are constructed as universal, normative and contingent. As a result, non-white PE practices and students are positioned on the margins in contemporary policy texts. By revealing the racialisation processes evident in the texts, we aim to trouble the profession's taken-for-granted truths about race in PE as integral to working towards the development of an antiracist subject.

Sport and Racial Discrimination in Colonial Zimbabwe: A Reanalysis

The British colony of Southern Rhodesia, later governed by a white settler minority as unilaterally-independent Rhodesia, practiced racial segregation in many spheres, including education, health care access and political participation. Though racial segregation tended to exist on a less formal level than in Rhodesia's neighbour, apartheid South Africa, segregationist policies were nonetheless invasive and virtually complete in some areas. Sport was a heavily contested sphere, in which pockets of black African autonomy and advancement existed alongside near-complete white domination, largely, but not entirely, free of government intrusion. This article is an effort to develop a working hypothesis of racial discrimination in Rhodesian sport, discrimination that was never as formal or complete as in South Africa but which nonetheless provided a firm foundation for Rhodesia's exclusion from international sporting competition in the 1970s.     

《逍遥游（节选）》教材注释商榷

“類”与“禷”祭

《诗经》、《尚书》、《周礼》、《礼记》等经籍提到的“禷”祭(又作“類”祭),是上古中国一项有着深厚民俗文化背景和深远历史影响的祭仪。不幸其礼早亡,汉儒已经难究其详。影响及今的《尚书》古文家说和郑玄《礼记》注等,将“禷”祭解为祭天之礼。但根据经籍中的记载来看,“禷”祭指的是当国有大事时,向上帝或社稷宗庙祈福禳灾的一种“祷祈”仪式,与祭天之礼并不是一回事。据《说文解字》等书,“類”字本义是一种犬,可能是白犬。“禷”祭应是指特以“類”为牺牲的祭仪。《山海经》等说“類”具有“自为牝牡”的神奇特性,这与该书所记“白犬有牝牡,是生犬戎”的传说非常相似。在先秦文献中,“類”字常用来指出自同一祖先的子孙后代。这些材料表明“類”与古代中国某些族群的祖先神话有着密切的关系。“禷”祭之形成,正植根于此种观念之上。“禷”祭当属于曾广为流行于上古中国北方地区的犬祭礼俗中某种特定的类型,它的消亡可能与周人颇具理性色彩的的礼制改革有关。     

γ射线暴:从中子物质到夸克胶子等离子体的相变

指出快速旋转的新生中子星内部存在着从正常强子物质到夸克胶子等离子体的相变过程,而γ射线暴所释放的巨大能量可能正是这种相变过程的结果。在新诞生的中子星通过偶极电磁辐射和四极引力辐射损失能量而减速时,其中心密度增加,并可能达到QCD的相变密度(原子核密度的5～10倍)。这种相变所释放出的能量可以解释γ射线暴的强大能量暴发及其聚束效应。γ射线暴位置附近相当致密的气体环境和在其X射线余辉中金属发射线的观测是对这种观点的支持。我们还给出了一些预言。
