“为了一切的人”与“为了人的一切”--当代知名教育家朱永新人文教育及阅读观解析

当代教育家朱永新通过发轫于苏南地域的“新教育实验”,并以“书香校园”建设为抓手,形成了独树一帜的“新阅读观”,传递了教育是“为了一切的人”与“为了人的一切”的新人文理念。论文通过回望朱永新的读书求学经历、“新教育实验”的实施过程、推进全民阅读的不懈努力及对未来教育生态的展望,解析了其教育及阅读观的形成过程和丰富人文内涵,认为这种努力追求理论与实践相结合并不断创新的知行合一精神,为助推“书香中国”、建设“学习型社会”发挥了独特的作用和别树一帜的贡献。     

Aroma changes of black tea prepared from methyl jasmonate treated tea plants

研究目的：为茉莉酸甲酯诱导来提高茶叶香气品质提供理论依据,为新型花香红茶的研制提供技术支持。创新要点：首次将茉莉酸甲酯应用于诱导茶叶香气品质提高,初步验证了茶叶香气品质提高的本质原因：相关酶活性提高,基因表达上调。研究方法：采用顶空固相微萃取法（HS-SPME）对红茶香气进行富集,气相色谱-质谱联用仪（GC-MS）进行解吸附分析,实时定量多聚酶链式反应（qRT-PCR）分析茶鲜叶中香气相关酶基因表达。重要结论：茉莉酸甲酯诱导后的茶鲜叶中多酚氧化酶（PPO）活性上升,β-葡萄糖苷酶活性下降;PPO和β-樱草糖苷酶基因表达上调,β-葡萄糖苷酶基因表达下调。茉莉酸甲酯诱导后的茶鲜叶能明显提高由其制成的红茶香气品质,且萜烯醇类和萜烯类含量明显提高。     

基于NDVI的内蒙古植被动态变化分析

植被对于生态环境变化的反应是较为敏感的,研究植被动态变化对生态环境的保护和生态预警有很大的意义.基于SPOT/VEGETATION NDVI数据,该文获得了内蒙古的空间NDVI分布,分析了自1998年至2008年之间NDVI的变化趋势.并由最大值合成法（MVC）,Mann-Kendall检验和Rescaled范围（R/S）分析计算出NDVI时间序列的赫斯特指数.此外,通过叠加分析对研究区域NDVI的未来变化趋势进行判断.主要的研究结果包括：第一,1998年到2008年间,内蒙古的植被变化总体上是稳定的,但数据显示10.16%的植被有显著减少的趋势,它们属于脆弱的草原植被;其次,在空间分布方面,NDVI时间序列存在一定规律,赫斯特指数在西部高,东部低;第三,在低植被覆盖区存在植被减少的现象.其中9.58%的土地开始衰退,这些土壤急切的需要植被的保护和综合的管理.没有人类的干预,这些土地将会出现荒漠化.

Differences in teachers' perceptions of personal control of positive versus negative student learning outcomes

Past research on teachers' causal attributions has shown there to be little relation between perceptions of responsibility for positive versus negative student learning outcomes. In this study, Weiner's model for causal attributions was employed to explore these perceived attributional differences. Data were gathered from 184 teachers from two metropolitan school districts. Statistically significant differences between attributions for positive versus negative outcomes were identified along the dimensions of both internality/externality and stability of cause. Relations to overall efficacy, teaching experience, grade level taught, and teacher gender were also explored; however, only grade level differences were found to be statistically significant.     

学校开展游泳运动的冷思考

近年中国竞技游泳在国际舞台上从突破到多点开花,游泳也列入部分省市中考项目,为学校游泳的发展注入了强心剂,也标志着校园游泳建设即将驶入快车道。校园游泳热凸显,但其健康、可持续发展必定依靠成可操作、可落地、可监测、可评估的举措。研究认为校园游泳要坚持育人之本质;要坚持正确的角色和功能定位;应助力终生体育意识的养成;建设需强调教与学方式方法的创新与改革;发展要坚持思则变、变则通、通则达的理念。

Crowdstorm: the future of innovation,ideas, and problem solving

This paper considers the scope for beneficial scientific co-operation and technology transfer among ASEAN countries, Australia and New Zealand in the light of differences in the development status of these countries, their proximity to one another, their resource endowments and other factors. Australian official science and technology aid in the ASEAN region (which of necessity involves some co-operation between the donor and aid recipients) is considered as well as recent initiatives of the Australian Department of Science to promote fully co-operative (‘non-aided’) R&;D in the region. Two examples of regional co-operation in R &; D are considered briefly, namely the development of a malaria vaccine and giant clam farming.     

Diffusion of R&D within the Australian Wine Industry

The Australian wine industry's popular image as a leader in R&D can indeed be substantiated. Its oenological and viticultural innovation and technical expertise have set new international benchmarks. The coordination of this R&D has ensured that the industry remains at the leading edge. However, the findings of this paper also substantiate concerns that this R&D is concentrated in what appears to be a South Australian R&D 'epicentre'. Regions and wine operators not connected to this epicentre can be disadvantaged. This paper examines the diffusion of R&D to regional operators and suggests mechanisms for improvement of the current structure.     

Revolution in Miniature. The History and Impact of Semiconductor Electronics Second Edition by Ernest Braun and Stuart Macdonald (Cambridge University Press,Cambridge, 1982) pp. viii + 247, $A15.50 (pb), ISBN: 0-521-24701-2 (hb), 0-521-28903-3 (pb)

This paper provides a review of Israel's science and technology policy and traces the growth and development of technology intensive industry in that country. Such policy has generally been neutral with regard to industry, technological field or class of product; concentrates on industrial R &; D directly performed in industrial firms; and is an integral part of overall national industrial policy — being centred in the Ministry of Industry and Commerce. Drawing upon case studies and other statistical evidence, the paper argues that such policy has been partly responsible for Israel's success in building up an indigenous, export-oriented, high technology sector.
