战略性关键矿产资源供给安全研究综述与展望     

吴巧生  周娜  成金华 《资源科学》2020,42(8):1439-1451

战略性关键矿产资源事关人类社会持续发展、在关键领域发挥战略性作用。本文从战略性关键矿产资源的界定与遴选、供给风险评价与预警、供给安全体系优化与政策三方面对当前研究进行了综述。主要结论有：①战略性关键矿产资源是满足国防军事需求与实现战略性关键产业良性发展的原材料,是一个国家或地区主权属性的集中体现,需结合国家或地区发展实际动态遴选战略性关键矿种;②战略性关键矿产资源供给风险具有更强的模糊性与不确定性,战略性关键矿产资源供给风险评价模型的建立面临诸多挑战;③通过全球资源优化配置,完善全球治理体系,是战略性关键矿产资源供给安全体系优化与政策选择的重要方向。从多学科交叉研究供给安全的形成机理,由大数据驱动与全球供给链跟踪明确供给风险评价要素,基于外部冲击因素和内部产业因素结合的视角完善战略性关键矿产资源供给安全政策是未来战略性关键矿产供给安全研究的重要方向。  相似文献   

A Minority within a Minority? Social Justice for Traveller and Roma Children in ECEC     

Colette Murray 《European Journal of Education》2012,47(4):569-583

This article discusses recent policy developments in Europe regarding Roma and Traveller integration and Early Childhood Provision. After a long history of oppression, Roma issues have recently become prominent on the EU policy agenda. The article discusses how these relate to developments in other areas of policy: the European children's rights agenda and the recognition that early childhood education and care is a key policy tool to combat social exclusion. It gives background information on Roma and Travellers in Europe and discusses the consequences of subsuming the various communities under one umbrella term: Roma. The EU Commission is concerned with responses from Member States to the European Framework for National Roma Integration Strategies. The article argues that in order to address Roma children's experience from a holistic perspective, social justice and equality need to be key elements of early childhood education and care provision and training. The European policy developments that frame the article are examined from a local vantage point: the experiences of Traveller and Roma children in Ireland and the Irish Preschool Education Initiative for Children from Minority Communities.  相似文献

论早期体育教育的重要性     

吴新文  李建项 《体育科学研究》1998,2(4):83-85

新中国成立后党和国家非常重视体育事业,我国运动员在参加国际性比赛和奥运会的角逐中都取得了较好成绩,群众体育运动也得到了广泛的开展。尽管如此,中国并未进入世界体育强国之列。为了迅速使中国体育崛起腾飞,把我国建成世界体育强国,当前首要任务是为发展体育事业,培养各类体育人才,使体育人才队伍迅速壮大起来,其中最为关键和迫在眉睫的任务就是要研究体育人才的早期教育问题。  相似文献

二元与一元运动训练理论辨析   总被引：2，自引：0，他引：2  

顾善光  陶于 《体育学刊》2007,14(5):19-23

通过对二元与一元训练理论的分析认为,两种理论构建基础以及产生分歧的主要原因是对体能与技术关系的认识问题,特别是对早期训练专项化及专项化过程中体能与技术相互转化关系的认识。运动训练最终目的是发展竞技能力、提高专项运动成绩,体能与技术是专项竞技能力结构中的重要组成部分,体能与技术的高度统一是发展专项竞技能力的重要途径,而早期专项化训练过程中体能与技术的相互转化才是专项竞技运动能力发展的关键。两种"理论"在指导具体的训练实践方面应是相辅相成的关系。  相似文献   

The Literacy Early Action Project (LEAP): exploring factors underpinning progress with literacy for a child in his first year of school     

Anthony Feiler  Elaine Logan 《British Journal of Special Education》2007,34(3):162-169

In this article, Anthony Feiler, senior lecturer in the Graduate School of Education at the University of Bristol, and Elaine Logan, lecturer in early years education at the City of Bristol College, present a case study of a child who made strong progress with literacy during his first year at school. The child and his family participated in the Literacy Early Action Project (LEAP), a home-visiting scheme for children judged by school staff to be at risk of struggling with literacy. A teaching assistant made weekly home visits during the year and developed literacy support activities with the child's mother and grandparents. Five key factors underpinning the child's progress are identified here: the flexibility in the teaching assistant's approach that enabled extended family members to become engaged in literacy support; the teaching assistant's sensitivity to family culture; the playful approach to learning adopted by the teaching assistant; putting the child at the centre of the intervention; and the existence of a school culture that strongly promoted involvement for parents. Anthony Feiler and Elaine Logan conclude that teaching assistants in the UK might be given more scope to develop support strategies for early childhood education that involve collaborative work with parents.  相似文献

家庭中早期阅读材料选择出现的问题及建议     

李童童 《科教文汇》2015,(5)

幼儿早期阅读能力影响其智力与非智力方面的发展,更是父母对幼儿情感培养的重要途径。因此,如何更有效地选择适合幼儿阅读的材料是目前家长面临的重要问题。但家长在选择早期阅读材料时经常出现问题。有的家长凭借自己的喜好购书,忽略了幼儿的年龄特点和兴趣所在;有的家长选择材料比较单一,约束了幼儿的思维发展方向;有的家长选择时重视数量,却忽视了材料本身的质量。针对以上问题,家长应根据幼儿身心发展特点选择阅读材料,选择贴近生活、通俗易懂的材料,并从多角度选择适量的阅读材料。  相似文献
