对结构概念与构造式表示体系称谓的商榷

笔者在浏览高中化学新课程标准的各种教材版本时,发现新版教材都依旧延续着旧有的版本结构式的称谓错误,这主要是由于教材著者有意或无意间混淆"结构"和"构造"这两个概念而造成的.笔者同时发现,国内不同版本的大学教科书中对于不同类型构造式的称谓也存在着不同表述,情形显得较为混乱.因此,本文拟针对结构、构造概念的界定和国内构造式表示体系的称谓问题作一个简单的讨论.     

从藩属国到殖民地-论越南对外关系转型(1804-1885)

阮朝是越南历史上最后一个封建王朝。随着工业文明降临于世,阮朝对外关系的危机和契机同期出现。中越宗藩关系走向瓦解有着必然性,然而阮朝却存在避免沦为殖民地的可能性。但阮朝未能把握此契机,最终历经由中国的藩属国向法国的殖民地转型。     

Project Spraoi: two year outcomes of a whole school physical activity and nutrition intervention using the RE-AIM framework

We aimed to assess the impact of Project Spraoi: a school-based physical activity (PA) and nutrition intervention that reached 473 primary school children and 43 school staff in Cork (Ireland). Four primary schools (2 intervention, 2 control) with similar characteristics participated and for 2 school years, intervention schools were assigned an ‘Energizer’, who promoted PA and healthy eating. A subsample of children from the intervention schools (n?=?106) and matching controls (n?=?125) had measures of body mass, waist circumference, blood pressure, fitness, nutritional knowledge/attitudes and PA recorded at baseline and after 2 school years. Process evaluation techniques assessed the impact of the intervention on teachers, parents and children. Analysis of covariance revealed the intervention was associated with smaller waist circumference relative to gender and age (p?<?0.0005), slower resting heart rate (p?=?0.003) and favourable nutritional attitudes among 10 year olds. No significant change across other variables or among 6 year olds was found. Teachers, parents and children reported positive outcomes for PA behaviour and nutritional knowledge/attitudes. Project Spraoi has shown to improve heart rate and prevent further gains in fat mass amongst older aged children. The positive impact of the intervention supports the need for its continued delivery, particularly as children age.

大学生自杀危机及其干预

危机干预是指针对处于危机状态的个体及时给予适当的心理援助,使之尽快摆脱困境。危机干预可分为预防性和补救性两种。目前各高校的危机干预机制多数停留在补救阶段,预防性的干预机制还不普遍。文章分析了自杀个体的心理,结合危机干预的预防性和补救性特点,提出了如何预防和干预大学生自杀行为的具体措施和建议。这些措施和建议有良好的操作性,对于从事高校学生工作者有实际指导意义。     

词类设置的现状及取舍

汉语词类的名称和数量,差异都很大。就名称而言,有的名同实异,有的名异实同;就数量而言,有的体系仅8类,有的体系达19类。研究各体系词类设置的现状,可以从比较中决定取舍,从而拟定词类设置的方案。     

通过变式教学培养创新意识——初中几何数学个例分析

培养学生的创新精神与实践能力,是素质教育的核心,是课堂教学的真谛。长期的教学实践表明,在数学课堂中充分利用一些典型范例和探索性习题,通过适当改造条件和挖掘引伸实施变式教学,可以在培养学生的正向思维、直觉思维和集中式思维的同时,促进学生的逆向思维和抽象思维的发展。在培养学生思维的逻辑性、广阔性和流畅性中,使学生形成良好的思维品质,养成创新精神和提高实践能力。现就初中几何教学,举例剖析如下。例1ABCD中,E、F分别为AD、BC中点,求证EB=DF.(《几何》第二册P.141,例题2)1.基本思路先让学生掌握证题的基本方法,如图1:①…     

Dropping out because of the others: bullying among the students of Estonian vocational schools

Although it is arguably a fundamental democratic or human right of a child to feel safe at school, many children and adolescents have to face peer victimisation in schools on a daily basis, and occasionally through several levels of education. Long-term victimisation may have detrimental consequences for the victim, including a negative effect on educational attainment. This study provides an insight into the lives of five young people who have dropped out or are at risk of dropping out from Estonian vocational schools because of peer victimisation. The study is based on in-depth face-to-face personal interviews. Four superordinate themes with associated subthemes are addressed: ‘experience of victimisation’, ‘social context’, ‘lack of support’, and ‘quitting as a survival strategy’. The stories of the bullying victims reveal how the victimisation has shaped them and their educational pathways by compelling them to discontinue their vocational training.
