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     

Including children with special educational needs in physical education: has entitlement and accessibility been realised?

The return of the Labour government to power in 1997 brought an increased focus upon inclusive education for children with special educational needs (SEN). Alongside this there has been a desire to enhance the opportunities young people have to access physical education (PE) and school sport. Previous research has shown that children with SEN often have fewer opportunities to access physical activity due to physical, social and emotional barriers to participation. With the advent of a new Con–Lib-Dem government in 2010 and a planned review of inclusion policies and practices, this paper examines the extent to which children with SEN have arrived at utopia in relation to their entitlement and access to PE. The paper identifies four themes central to successful inclusive PE, whilst suggesting there is still some way to go for children with SEN to have the same opportunities in physical activity as their non-disabled peers.

Campus Walkability,Pedometer-Determined Steps,and Moderate-to-Vigorous Physical Activity: A Comparison of 2 University Campuses

Objective and Participants: At 2 Arizona State University (ASU) campuses, the authors measured student activity and distance walked on campus, as well as student-reported walkability around the student union. Methods: Students from ASU-Polytechnic (n = 20, 33% male) and ASU-Tempe (n = 20, 60% male) recorded distance walked on campus and wore physical activity monitors for 5 days. Results: Polytechnic students spent an average of 36.9 minutes in moderate-to-vigorous physical activity each week; Tempe students spent 69.5 minutes (p < .001). At Polytechnic, students walked an average of 7,674 steps per weekday; at Tempe, 11,294 steps (p = .003). Female students at Polytechnic walked an average of 1.3 km/d; at Tempe, 4.3 km/d (p < .001). At Polytechnic, men walked an average of 1.4 km/d; at Tempe, 3.1 km/d (p = .03). Tempe students rated campus walk-ability as very good, whereas Polytechnic students rated it fair (p < .001). Conclusions: Students at both campuses met activity recommendations; noted differences may be attributed to the built environment's contribution to walkability.     

学生体育效果目标评价方法的研究

长期以来 ,体育效果的评价没有考虑学生生长发育的非同步性及身体素质的个体差异 ,不利于对学生进行个性教育。目标评价引入了目标完成等级的指标 ,既能够描述学生体育能力的个体水平 ,又能够准确体现体育学习过程的前后变化 ,是一种相对合理的体育效果评定方法。目标评价方法对促进教学目标向学习目标转化 ,终结性评价向过程性评价转化 ,实施个性教育 ,推进素质教育的开展 ,有着深远的意义。     

浅析笛卡尔的二元论和西方近代哲学中的身心关系问题

心身问题或心物问题(mind-body problem),是关于心理的东西(the mental)的本体论地位,本质以及与身体的相互关系的问题。在西方认识史上,先哲们对这个问题分别给予了缜密思考后的回答。本文首先回到西方近代心灵哲学上一个颇有影响的心灵观,从笛卡尔的实体二元论说起,分析其内在逻辑矛盾产生的根源和面临的困境,再集中探讨与笛卡尔同时代的哲学家们对其观点的改进或改造,并逐一做出梳理和短评。
