1960～2005年拉萨市冬季强降雪成因诊断分析

通过对1960～2005年11～3月日降雪量≥4.0的20次强降雪的环流型式、水汽条件、能量条件、西藏地面区域小图和探空资料的综合分析.以便从历史资料中找出天气过程的规律性,有效地提取对拉萨市冬季强降雪具有信息价值的那部分.本文初步探讨了45年来拉萨市冬季强降雪的成因.     

浅谈母乳喂养的作用与分娩前后乳房的护理

妇女妊娠是一种生理过程，但也有少数孕妇有可能发生病理变化，影响孕妇、胎儿和新生儿的健康，甚至还会对婴儿的智力发育产生更深远的影响。如能及时给予孕期保健或指导，做好早期预防，许多病理性变化是可以避免或转化的。妊娠期新陈代谢旺盛，孕妇的汗腺、皮脂腺分泌增多，乳腺分泌过量，乳房的血管及淋巴扩张，使乳汗淤积而引起乳房胀痛感，应积极指导喂奶和乳房的护理.     

Participation and rights of children with Specific Needs of Educational Support in Castilla y León (Spain): bridging the gap between policies and practices

ABSTRACT

The administration of the Spanish State is based on a decentralised model consisting of 17 autonomous regions. Castilla y León represents the largest region in Spain and the third largest in the European Union. Our analysis of both national and regional (Castilla y León) legislation on the rights of children and youth with Specific Needs of Educational Support (SNES) to participate in education suggests that the relevant legislation incorporates the minimum standards proposed by various international organisations (UNCRC, UNCRPD). Nevertheless, socio-educational organisations and researchers report limitations and setbacks to the participation of children and young people in Castilla y León, which especially impact on children with SNES: no representation on Primary and Special Education School Boards, socio-economic segregation at some schools, and scarce social participation with disadvantages for girls and other vulnerable groups. In view of these challenges, we set out to ascertain the impact of legislation on the rights of children, by listening to the voices of children with SNES. Our research, a replication of a British project, is adapted to our region. We expect to perform comparative analyses, to learn from other examples of good practice, and to offer innovative proposals for international implementation and dissemination.     

基于语义扩展的数字文献自动分类方法研究

针对图书、期刊论文等数字文献文本特征较少而导致特征向量语义表达不够准确、分类效果差的问题,本文提出一种基于特征语义扩展的数字文献分类方法。该方法首先利用TF-IDF方法获取对数字文献文本表示能力较强、具有较高TF-IDF值的核心特征词;其次分别借助知网(Hownet)语义词典以及开放知识库维基百科(Wikipedia)对核心特征词集进行语义概念的扩展,以构建维度较低、语义丰富的概念向量空间;最后采用MaxEnt、SVM等多种算法构造分类器实现对数字文献的自动分类。实验结果表明:相比传统基于特征选择的短文本分类方法,该方法能有效地实现对短文本特征的语义扩展,提高数字文献分类的分类性能。     

谈高职院校如何有效利用MHK考试提高汉语教学质量

学习语言的最终目的是运用语言进行交际,落实到语言交际中,语言能力具体又可分为听、说、读、写四种能力。职业院校的汉语教学有着自己的特殊性和不可比性,应该探索出一条符合自身特色的汉语教学发展之路,充分利用MHK考试制度,提高学生学习的积极性及应用汉语的能力,使汉语为教学服务,为专业所用,从而促进新疆少数民族职业教育的发展。
