明代白银货币化:中国与世界连接的新视角

晚明时期,中国社会面临着重大变迁;同时,世界经济也正处于融为一体的进程中。明初,白银并非合法货币,由于中国社会内部发生的变化,白银货币化自下而上到自上而下初步奠定,产生了巨大的社会需求,市场经济萌发并以前所未有的发展趋势极大地扩展,不仅拉动了外银流入,而且使中国由此主动走向了世界。事实并非如既往所认识的,是西方东来导致了中国被动地与世界衔接起来。从时间和动因上看,中国的社会需求曾直接影响了日本和美洲银矿的开发,中国积极参与了世界经济体系的初步建构,并为整体世界的出现作出了重要的历史性贡献。当世界逐渐形成一个整体世界之时,世界经济体系不是西方创造出来的,而是世界各国共同创造的。

Macroeconomic asymmetry in the Eurozone before and after the Global Financial Crisis: An appraisal of the role of the ECB

The launch of the euro in 1999 was assumed to enhance macroeconomic convergence among EMU economies. We test this hypothesis from a comparative perspective, by calculating different indices to measure the degree of macroeconomic dispersion within the Eurozone, the UK and the USA (1999–2019). We use common factor models to produce a single index for each monetary area out of different measures of dispersion. These indices can be used to inform on the degree of optimality of a monetary area. Our results show that macroeconomic dispersion in the Eurozone increased notably even before 2007 and it took significantly longer to return to pre-crisis levels, as compared to the UK and the USA. The paper shows the critical role played by the ECB’s asset purchases programmes in reducing macroeconomic divergences among EMU member states since 2015.     

手段论与目的论视角下学校体育的有效性思辨

长期以来,有关学校体育是素质教育的手段还是素质教育的目的的问题争论不休。目的论从学科的角度出发,认为学校体育的本质功能就是增强学生体质、提高学生健康水平,评价学校体育的有效性就应该看学生的体质和健康水平状况;手段论从教育的角度出发,认为学校体育是学校教育的一部分,是和学校其它教育相配合为培养全面发展的人服务的教育手段之一。研究认为,手段论和目的论并不是完全对立的,学校体育的教育性是在立足学科功能的基础上体现出来的;所以,学校体育既是素质教育的手段也是目的。     

试论社区体育与学校体育的互动发展

大体积混凝土掺矿粉的试验与应用

矿渣微粉可以改善砼的性能,提高砼密实度,改善砼的和易性,并且可以降低砼水化热,增进后期强度、提高抗腐能力,尤其是磨细矿物掺合料对碱一集料反应的抑制作用。作用辅助胶凝材料的矿粉得到了广泛的认可。     

西北普通高校大学生体育锻炼意识与运动兴趣的调查研究

通过对西北普通高校大学生体育锻炼意识、健康状况与运动兴趣调查分析表明 :大学生喜欢上体育的人数不到 6 0 % ,相当一部分学生对体育的健身价值缺乏正确的认识 ,没有体育锻炼的习惯和意识 ;学生的体质健康状况不理想 ,必须引起有关领导的重视 ;学生对健身类、健美类、娱乐兴和球类体育活动比较感兴趣 ,学校应多为学生提供这方面的教学和活动场所。     

Child protection services and parental reactions to children's behaviour

A commonly used expression in child protection is the term 'physical abuse'. This paper consists of a quantitative and qualitative analysis of a 100% sample of 'physical abuse' child protection cases drawn from research in an Australian state child welfare agency, which shows that about 90% of these concerned incidents in which parents used physical punishment to control children. Resulting physical harms to children (where they occurred) were generally of a very minor nature. The paper examines these results in the light of research findings in the UK and Australia on patterns of physical punishment used by parents to control children. Such findings suggest that those child rearing practices that make frequent and systematic use of physical punishment are located largely amongst lower social class parents, who believe that such practices are an essential and normal component of effective parenting behaviour. One interpretation of child protection services in respect of these cases is that they are concerned primarily with the normalization of child rearing practices. The paper concludes with a discussion of the limited impact of the Swedish anti-spanking law of 1979, which appears to have only reduced the use of physical punishment by those parents who may not necessarily have believed in such measures in the first place. However, legislation of this nature has the potential to criminalize a substantial sector of the population, but at least state intervention under the aegis of a specific criminal law provides a clearer mandate than does intervention under much looser, broader and subjectively interpreted child protection legislation.     

物理学史在物理教学中的应用

论述物理学史在培养学生兴趣、科学精神和帮助学生领会物理知识等方面的功能.在物理教学中渗透物理学史教育,有利于学生巩固和加深理解已学过的物理知识,增加学习的主动性与自觉性,提高学习兴趣,培养学生的创新精神.因此在物理教学中有必要进行物理学史教育.     

物流产业问题研究综述

目前 ,物流产业已成为继制造业和商业之后的第三利润源 ,作为一个专门的产业加以开发。现代物流产业具有大跨度性、动态性、可分性和复杂性的特征。我国物流产业尚存在观念落后、设施陈旧、发展不平衡、物流业与电子商务脱节、人才短缺、技术单一、缺乏规模效应等问题。我国要大力发展第三方物流。我国的物流产业必将朝着国际化、电子化、共同化、专业化、个性化、信息化的方向发展
