基于《中图法》的网络农业信息分类编码研究

针对目前农业网站信息管理与共享的需求,提出了一套网络农业信息分类编码体系.通过分析国内代表性农业网站信息分类的特点及<中图法>网络应用的优缺点,以"华中农业信息网"多年采编的信息作为实验材料,在考虑网络农业信息特点的基础上对<中图法>的农业及相关类目进行了网络适应性改造,进而提出了网络农业信息分类编码方法.该体系克服了全新分类体系网络应用性差、信息覆盖面不全的问题.研究结果对网络农业信息有效管理,提高信息利用率,促进信息资源共享具有积极作用.

Synthesis and Characterization of Three Pentacene Derivatives

The addition of substituents at the 6,13-position improved the solubility and stability of pentacene, making it possible to use the derivatives in spin coating of organic field-effect transistors(OFETs). Three pentacene derivatives, 6,13-bis(m-tolyl)pentacene(MP), 6,13-bis(4-butylphenyl)pentacene(BP), and 6,13-bis((4-butylphenyl)ethynyl)pentacene(BPEP) were synthesized, and their properties were investigated. 6,13-Pentacenequinone and organolithium were used in the preparation of 6,13-dihydropentacene at 0 ℃, and pentacene derivatives were synthesized with SnCl_2/HCl as reducing agent, to reduce 6,13-dihydropentacene at room temperature. The structure of the derivatives was characterized using NMR. The thermal stability, photochemical properties, and electronic structure of the three compounds were investigated using TGA, cyclic voltammetry, and UV–Vis. BPEP was also characterized using X-ray diffraction and atom force microscopy. BPEP was used to fabricate an OFET device using spin coating. The device showed a mobility of 0.07 cm~2 V s~(-1) at V_(th) =-10 V and I_(ON)/I _(OFF) = 10~2.     

中等职业学校共享型实训基地运行问题及对策研究

中等职业学校的实训基地是实践教学的主要场所,是提高学生职业技能的主要途经,加强实训基地建设是办好职业教育的关键所在。本文选取浙江省几个典型中等职业学校实训基地进行实地调研,对中等职业学校实训基地建设现状进行分析,发现实训基地在运行中存在诸多问题,笔者提出共享型实训基地这一概念,并探讨了共享型实训基地建设意义及运行模式,从共享型实训基地运作的外部保障机制与内部管理机制提出一些对策,为中等职业学校实训基地走向优质、高效运行之路提供参考性意见。     

农村中学高一英语教学之浅见

普通高中英语课程是义务教育阶段课程的自然延伸,是基础教育阶段课程的重要组成部分.因此,普通高中英语课程要在义务教育英语课程的基础上,帮助学生打好语言基础,为他们今后升学、就业和终身学习创造条件,并使他们具备作为21世纪公民所拥有的基本英语素养.高中英语课程应根据高中学生认知特点和学习发展的需要,在进一步发展学生基本语言运用能力的同时,注重提高学生用英语获得信息、处理信息,分析和解决问题的能力,逐步培养学生用英语进行思维和表达的能力,为学生进一步学习和发展创造必要的条件.     

如何评价情感、态度和价值观

如何评价学生的学业成绩是课程改革的难点之一,情感、态度和价值观评价更是难点中的难点。从评价范围、评价指标体系、评价工具和评价实施办法等方面论述对情感、态度和价值观的评价,对研究情感、态度和价值观评价具有一定参考意义。

斯蒂芬·克拉申"监察模型"中的"情感过滤假说"理论与第二语言教学

在第二语言教学理论发展过程中,对第二语言转化机制的研究已由加工的观点逐渐取代了传统的存储观点。本文全面客观地介绍了斯蒂芬·克拉申穴Stephen·Krashen雪教授在二十世纪八十年代中熏后期提出的一套完整的第二语言习得模型监察理论中的“情感过滤假说”(filterhypothesis)的主要内容及其形成的基础以及上世纪九十年代国际语言理论界对此理论的看法,对影响第二语言教学中认知过程的情感因素进行了分析和讨论。     

The development of children with down syndrome: the influence of maternal adaptation,mother-child interaction and early forms of support

In this paper, we present a longitudinal case study involving four dyads with babies with Down syndrome from birth until the age of 7 years – the moment at which the children were observed for the last time before they began compulsory schooling. At each data collection point, the mother was given a semi-directive interview and we filmed a free interaction situation. The objective of our study was to carry out an indepth analysis of the ways in which mothers adapt to the birth of a ‘different baby’, the evolution of their expectations in relation to the child's development, mother–child interaction and early support for both the child and the family, and the way in which these aspects of the overall situation relate to the children's development. The data of our longitudinal study show that there is an interaction between children's development and family characteristics and patterns, particularly mother–child interaction and the way in which the mother deals with the stress factors associated with the fact that she has a disabled child. We found that the four dyads experienced different models of early support, which to some extent reflect what really does happen in Portugal in cases involving children with disabilities, and that the programmes' impact was not identical in every situation. The most successful was the one which best suited the family's wishes, and involved both the mother and later on the kindergarten teacher.
