1962年至2006年中国西北区与季风区春季气温变化特征对比

本文利用1962年-2006年我国西北地区138个站点和东部季风区377个站点春季平均气温资料,采用EOF分解、一阶线性函数和相关性检验等方法,对西北干旱区和东部季风区春季气温的时间变化和空间异常分布特征进行了对比分析,并从大气环流和海洋热力作用等方面对两个区域春季气温变化的异同点进行了探讨。结果表明:近45年来,西北干旱区和东部季风区春季平均气温以升高趋势为主,西北干旱区春季气温变化年际间振幅大于东部季风区;总体的升温趋势以东部季风区较强为主;同时两个区域存在明显的周期差异,使西北区升温在时间尺度上较季风区略偏迟,两个区域都存在升温的敏感区,从而影响着两个区域春季气温的整体变化特征。     

《吕氏春秋》的天道观和天命论

《吕氏春秋》认为天地的性状具有客观必然性,人事应以之为准则;天地的法则和谐有序,故要“法天地”而建立和谐有序的封建秩序;天命是客观事物发展变化给人造成的遭遇,但君权是天授。其天论主要是上继荀子等多家的思想而更树独立见解,这反映了进步的新兴地主势力的思维。其总的倾向是坚持了朴素唯物论和辩证法,但也有其局限性。

《吴越春秋》死亡叙事的文化内涵及艺术功能

《吴越春秋》作为东汉时期一部著名的杂史著作,其死亡叙事取得了较高成就。它折射了崇尚人生命的社会属性而轻忽其生物属性的生命观,体现了忠、孝、节、义的伦理观。《吴越春秋》的死亡叙事有助于具体饱满地展现人物的性格特征,塑造生动逼真的人物形象,对增强作品叙事的生动性、有机性也有一定的作用。     

Networking or Not Working?

This paper examines journalists' changing sourcing practices in the context of an emerging media ecology initiated by processes of globalization, digitization, commercialism and concentration. Social media platforms such as Facebook, Twitter or YouTube provide the means to access a more diverse range of sources, including civil society organizations and ordinary citizens. We developed a quantitative content analysis to examine to what extent Belgian news coverage showed signs of diverse sourcing practices during the 2011 uprisings in three Arab countries. We analysed a total sample of 1121 news items about the street protests in Syria, Egypt and Tunisia, in four Belgian newspapers (two popular and two quality dailies) and two Belgian broadcasters (the public broadcaster VRT and the commercial channel VTM). The analysis shows that ordinary citizens and non-mainstream groups are important news sources and that social media platforms are consulted relatively often compared to everyday foreign news coverage. In terms of inter-media differences, the findings show that broadcasters' dependency on video footage and eyewitness accounts is reflected in their use of ordinary citizen sources and amateur footage. Moreover, the analysis confirms that quality newspapers display more diverse and more innovative sourcing practices than popular newspapers.     

Social Media as Primary Source

This article explores and critiques the use of social media as a primary source in the writing of twenty-first-century history. Since the introduction of so-called social media in the early 2000s, social scientists, journalists, and users have hailed this media form as a revolutionary departure from the ‘old media’ that dominated the twentieth century. Part of the narrative of ‘new media’ is it provides greater amounts of user agency, removes structural impediments for social dialog, and promotes an egalitarian exchange within the global sphere. This article suggests that this account is a product of the narrative structure of classical liberalism, through which social media as an object of knowledge and effectivity is produced. It concludes that the use of social media as a primary source for social histories of popular protest will require substantive theoretical scrutiny by scholars writing about these processes of the twenty-first century.

贵阳市打渔寨岩溶大泉水质污染成因及保护措施

贵阳市打渔寨岩溶大泉污染系工程建设开挖破坏了原生地形地貌,在大气降水、淋漓、冲刷等综合作用下,地表迳流沿裂隙、钻孔等渗入地下补给地下水所致.保护措施：施工工程应确保桩基砼浇筑回填不得堵塞补给打渔寨水源点的岩溶管道、溶蚀裂隙等通道,防止水源断流或者水量明显减小而导致无法供水;并且有必要向有关部门申请,划定饮用水水源保护区,建立水环境质量监测和水污染排放监测站,定期进行水样检验,以确保饮用水安全.
