An analysis of the regional disparity in the average educational expenditure per senior secondary student and its relevant factors in China     

Baifu Shen 《Frontiers of Education in China》2006,1(2):270-285

The essay deals with regional disparities in the average educational expenditure of every ordinary senior secondary student, including budget funds for education, the proportion appropriated to the ordinary senior high school by the government, tuition fee per student and the proportion of tuition fees of the total educational expenditure. By analyzing the relevant educational and economic indicators, we find that the average educational expenditure and tuition of every student in the western area are lower than those in the eastern and the middle area while the proportion of funds allocated by the government is the highest. However, in the middle area, both of the government appropriation of education funds for every student and its proportion of the total educational expenditure are the lowest in China, but on the other hand the proportion of tuition fee of the total educational expenditure and the income of the rural residents are the highest. Therefore, the aim of this essay is to look at the reasons why there are such differences.  相似文献   

Molecularly imprinted polymers as the extracted sorbents of clenbuterol ahead of liquid chromatographic determination     

Sovichea Lay  Hai-ning Yu  Bao-xiang Hu  Sheng-rong Shen 《Journal of Zhejiang University. Science. B》2016,17(6):465-475

A pre-treatment methodology for clenbuterol hydrochloride (CLEN) isolation and enrichment in a complex matrix environment was developed through exploiting molecularly imprinted polymers (MIPs). CLEN-imprinted polymers were synthesized by the combined use of ally-β-cyclodextrin (ally-β-CD) and methacrylic acid (MAA), allyl-β-CD and acrylonitrile (AN), and allyl-β-CD and methyl methacrylate (MMA) as the binary functional monomers. MAA-linked allyl-β-CD MIPs (M-MAA) were characterized by Fourier transform-infrared (FT-IR) spectroscopy and a scanning electron microscope (SEM). Based upon the results, M-MAA polymers generally proved to be an excellent selective extraction compared to its references: AN-linked allyl-β-CD MIPs (M-AN) and MMA-linked allyl-β-CD MIPs (M-MMA). M-MAA polymers were eventually chosen to run through a molecularly imprinted solid-phase extraction (MISPE) micro-column to enrich CLEN residues spiked in pig livers. A high recovery was achieved, ranging from 91.03% to 96.76% with relative standard deviation (RSD) ≤4.45%.  相似文献   

一种增强移动自组网Internet连接的改进型方案   总被引：1，自引：0，他引：1  

沈斌  李波  石冰心 《东南大学学报》2007,23(1):16-21

针对移动自组网因单向链路以及盲目转播网关发现分组而造成的与Internet互联性能下降,提出了一种增强型互联方案.同时结合了先应和后应网关发现策略优点的混合网关发现策略被用来获取良好的Internet连接并保持低开销.而通过交换携带有额外增加的对称邻居节点列表和非对称邻居节点列表字段的AODV hello分组,单向链路得以从路由计算中予以清除而广播风暴也同时得到抑制.基于ns-2的仿真结果表明此改进型Internet连接方案在单向链路数量及节点移动速度均变化的应用环境下能取得较其他方案为优的互联性能.  相似文献   

时代的热言——论《南方都市报》的新闻评论     

庄森 《广东技术师范学院学报》2007,1(11):20-27

《南方都市报》高度重视新闻评论,不但天天有社论,而且用两个版面刊发新闻评论,强化新闻评论与公众的需求和愿望的紧密联系,及时褒贬现实,评论公众关注和社会形成的热点蕴含的因素,满足公众和社会的需要,具有很高的新闻评论价值,极大地提升了《南方都市报》的品位和品牌。《南方都市报》的新闻评论还追求高端性与精英性的结合,刊发精英作者撰写的新闻评论,选取与公众利益密切相关的论题进行评论,显示出鲜明的广泛性和开放性的精英倾向,与流行的“公民写作”保持距离,代表着《南方都市报》追求高品位的旗帜。  相似文献
