Evaluating efforts to enhance health and wellbeing in Scottish secondary schools

Curriculum for Excellence in Scotland outlines a policy vision of a more progressive, integrated and holistic form of education; a commitment which contains an obligation for health and well-being (HWB) to be a responsibility of all teachers. A critical policy analysis approach was utilized in order to review school-level progress in different stages of policy development, i.e. policy formulation, legitimation, implementation and evaluation. Evidence was collected through 15 semi-structured interviews with head teachers, teacher education academics and staff with national and local authority quality improvement remits. Questions focused on: aims and curriculum goals; school culture; learning and teaching; partnership relationships and evaluations of practice. Findings suggest a high degree of support for curriculum aims, however, there were often problems communicating policy expectations (policy formulation). Thus, despite impressive examples of innovative practice in relation to school ethos, wider achievement and pupils’ broader general education (policy legitimation), there were also examples of HWB being constrained by senior school examinations and the backwash effect this had on curriculum planning and engagement with interdisciplinary learning approaches (policy implementation/evaluation). These findings have implications in terms of policy to practice coherence as well as highlighting the need for further more specific research evaluations.     

从语言的经济性和冗余性看英语学习中的语用充实

英语学习的目的在于交际，而交际的过程是理解意义的过程。具体话语意义的理解总是依靠一定的语境，是其在一定语境下对话语的语用充实。语用充实体现了语言经济性和冗余性的特点。

从某油田产出水中分离得到一株以原油为碳源的Pseudomonassp .菌 (假单孢菌 ) ,其化学趋向性运动能力中等 ,趋向性机理在本文中得以详细描述 .在可视化模型实验中可看到微生物向油水界面处的有序运动 ,而在有效的营养物浓度梯度范围内 ,化学趋向性运移速度与距油水界面的距离无关 ,受温度的影响很大 .并且在微观仿真模型实验中 ,可观察到细菌在孔隙壁和油、水三相交界处聚集 ,并讨论了该现象的形成原因及其对微生物采油的有利作用 .     

中国区域化肥利用特征分析

以化肥区划中的一二级分区为研究单元,分析了我国目前的化肥施用现状,以及不同区域在化肥施肥量和肥料比例等方面的特征及差异。结过表明：黄淮海平原区、长江中下游区和东北区是我国化肥消费的主要区域,化肥消费．6-量占到了全国消费总量的2／3多;其次为西南、华南和北部高原区,占全国化肥消费总量的30％;各一级区单质氮肥和磷肥的比例在逐步下降,而复合肥和单质钾肥的比例再逐步提高。但总体而言,磷氮比近几年各一级区变化不大,稳定在0．6左右,钾氯比还处于一个很低的水平;各区域单位播种面积化肥施用量从1983年到2004年有了很大的提高。东北区、西南区和西北区历年均为全国施肥水平最低的区域,而北部高原区、华南区、黄淮海区和长江中下游区为历年全国施肥水平最高的区域。

关联理论视角下词汇语用充实现象探究——以《爸爸去哪儿》主题歌词为例

词汇语用充实主要是研究词汇在特定语境中词义的语用收窄和语用扩充,关联理论认为人们对话语的理解就是寻求话语的最佳关联性,而对具体词汇进行语用收窄或者语用扩充都是利用百科知识、认知语境等对词汇理解进行语用充实并且获得所期待的最佳关联性.对《爸爸去哪儿》的主题歌词中特定词汇的触发进行语用推理后,发现对这些特定词汇不能直接进行原型解读,需要对其进行词汇语用充实后,才能更好解读歌词传递亲情为主题的交际意图.
