耶利内克戏剧《白雪公主》的互文性解析

《白雪公主》是奥地利女作家耶利内克的戏剧《死亡与少女》中的一部分,它与传统的格林童话在人物、情节和文字细节上形成互文性关系。但在主题上,它揭露并批判了女性潜在的奴性思想,同时又超越女性主义,直指人类终极命运——死亡。

Dietary overlap of snow leopard and other carnivores in the Pamirs of Northwestern China

Information about competition between carnivore species for food within high altitude regions is limited.Data collected from the Taxkorgan Nature Reserve,China revealed important interactions between snow leopard(Panthera uncia),grey wolf(Canis lupus),red fox(Vulpes vulpes)and their prey species,including domestic livestock.Sixty-four line transects were conducted in order to identify field signs of habitat occupancy and collect scats for diet analysis.High dietary overlap was observed between all three carnivore species:snow leopard and red fox(Pianka’s index=0.96),red fox and grey wolf(Pianka’s index=0.90),snow leopard and grey wolf(Pianka’s index=0.87).Snow leopard and grey wolf showed significant predation on livestock(36.8%for snow leopard and 29.4%for grey wolf in diet composition).As a pioneering exploration of the endangered snow leopard and its relationship with other species within the alpine ecosystem under livestock grazing pressure,this study contributes a greater understanding of the relationship within carnivore guild in the Pamirs whilst providing implications for conservation planning and project implementation activities in China.     

以赋为诗:“白战体”对《雪赋》写作方法的规避与继承

咏雪是咏物作品中分量极重的题材,而谢惠连的《雪赋》和宋代欧阳修、苏轼的"白战体"都是咏雪诗发展史上的标志性作品。通过梳理咏雪诗的写作技巧的发展,可以发现"白战体"写作技巧的创新性正在于对《雪赋》中一些未得到发展的写作方法的继承,这也可以视为宋诗"以赋为诗"之一端。     

2003—2020年新疆北部积雪因子时空变化分析

积雪作为冰冻圈的活跃因子之一,对气候环境的敏感性使其能够快速反映出与气温、降水等气候因素的关系变化,并影响着全球水文变化。对新疆北部地区2003年6月—2021年6月的中分辨率成像光谱仪(moderate resolution imaging spectrometer, MODIS)逐日积雪数据进行去云处理,并基于像元计算了积雪覆盖比例(snow cover percentage, SCP)、积雪覆盖日数(snow cover days, SCD)、积雪开始时间(snow onset day, SOD)和积雪结束时间(snow end day, SED)。实验结果表明：积雪产品相对于气象站点数据的总精度达到91.47%,有利于提高对积雪因子的时空变化分析。新疆北部地区SCD空间分布差异较大,SCD随海拔的升高而增加,SOD随海拔升高而提前,主要在11月和12月出现;SED随海拔升高而推迟,主要在2月和3月出现;夏季平均SCD最少,主要分布于天山中部以及阿尔泰山北部区域,约占3.35%,冬季平均SCD最为明显,大于60 d的区域占46.3%;而SCP在1月达到最大,7月和8月最小。趋势变...     

The literature and the science of ‘two cultures’ historiography

This paper discusses the historiography of the ‘two cultures’ controversy. C. P. Snow’s lament about the ‘two cultures’, literary and scientific, has inspired a wide range of comment—much of which begins by citing Snow and his thesis, before going on to discuss very different things. This paper focuses upon one strand of this commentary, the historical analysis of the controversy itself. A ‘historical’ analysis is defined here as one that resists the impulse to enter the argument on behalf of Snow or Leavis, to conceive of their argument in the terms that Snow defined, or to invoke their argument as a precursor to some contemporary issue. Instead, a historical interpretation registers distance between that day and this, takes the controversy itself as its object of study, and explores the tensions and associations that came to be packed into those now familiar terms. As the fiftieth anniversary of Snow’s Rede Lecture nears, this approach—rather than the repetition of clichés about the bridging of cultures—offers both analytical perspective on the controversy and interpretive possibilities for its examination.
