面对基础教育新课程,改革高师物理专业课程教学的思考

根据基础教育课程改革的要求,从课程理念、课程结构、教学方式、教学评价等方面提出高师物理教育专业如何应对这一改革的几点思考。     

大学综合英语课程的文化教学

大学综合英语课程中,文化教学理念的淡漠甚至缺失是导致教学效率低下的重要原因之一。文化教学从属于语言教学甚至被其取代,这种情况不利于学生跨文化交际能力的培养,在真实交际环境中容易产生焦虑,甚至对英语学习失去兴趣。显性和隐性文化教学法的结合能有效提高大学综合英语课程中的文化教学。     

新建地方本科院校双语教学探析

双语教学是当前高校教学改革的热点和难点,在理论研究和教学实践方面都取得了可喜的成绩,然而作为高等教育重要组成部分的新建地方本科院校,在双语教学开展方面却存在着诸多困扰。在对新建地方本科院校双语教学现状分析的基础上,提出了相应的对策,对新建地方本科院校更好地开展双语教学有一定的借鉴作用。     

以新课程理念指导词汇教学

词汇教学为中学英语教学的基础,教师必须遵循语言教学的规律,研究词汇教学和学生学习存在的问题,寻找有效的教学策略,采用灵活多变的教学方法,不断增强学生学习词汇的兴趣和意识,从而最终掌握词汇,达到学以致用的目的。     

Climate change transformation: A definition and typology to guide decision making in urban environments

Climate change presents a threat to the sustainability of cities and their societies, and must be adequately addressed. Urban environments (cities) are responsible for the creation of a significant amount of greenhouse gas emissions which are the source of climate change. Cities have been increasingly the focus of action to address climate change, yet emissions are not significantly reducing. Additionally, there a lack of integration between adaptation and mitigation. This prevents responses adequate to limit global warming to 1.5^OC, and to be well adapted to anticipated changes. This paper critically analyses existing definitions and typologies of climate change actions. A definition of ‘climate change transformation’ is proposed which includes the integration of adaptation and mitigation goals to enable a new regime in which global warming is limited to 1.5^OC. A new three-part typology: ‘coping, malaction and transformation,’ is presented for categorising climate change actions by the extent to which they integrate adaptation and mitigation, and define a new regime. The typology is accompanied by illustrations to demonstrate the relationship between adaptation and mitigation. The definition, typology and illustration serve to guide effective climate change decision making, and provides principles to guide application in urban environments.

新能源政策对上市公司股价影响的实证研究

中国目前正在快速发展新能源——新能源在帮助中国完成经济转型,实现能源安全的过程中发挥了巨大的作用。主要集中研究新能源政策的颁布如何影响上市公司的股价。以新能源上市公司为样本,分析在2008—2010两年间我国推出的两个国家级新能源政策对公司的影响。主要采用事件研究法,并期望找到支持政策变动导致公司利润增加的相关解释。研究结果表明,上市能源公司股票价格对于国家政策的颁布具有显著反应。这表明中国新能源产业受政策刺激效果明显,政策效应在短期内可从实体经济传导至相应的股票市场。

The colonial ascidian fauna of Fiordland,New Zealand,with a description of two new species

A total of 17 species from the families Styelidae, Polyclinidae, Polycitoridae, Pseudodistomidae, Ritterellidae and Didemnidae are described for the first time in collections from remote fiords with steep-sided walls, high rainfall and high tidal flow on the south-west coast of New Zealand. The Fiordland ascidian assemblages are composed of endemic species, species with trans-Tasman affinities, species found in southern New Zealand and species found New Zealand wide, some of which have global distributions. Two Australian native species, Diplosoma velatum Kott, 2001 and Didemnum jucundum Kott, 2001 from South Australia are new records to New Zealand and a further eight species remain undescribed. Two new colonial ascidians Aplidium coronum sp. nov. and Trididemnum shawi sp. nov. are described in this paper.
