Young people’s and parent’s perceptions of managed moves

The current research aimed to increase understanding of the experiences of young people and their parents of managed moves, what contributed to success and the nature of the challenges experienced. The study was conducted in one English Local Authority, where five young people and their parents were interviewed. Five superordinate themes emerged from the interviews, relating to: the initial process (people, trail period, managed moves as a positive solution); the reasons for the move (bullying/social isolation, breakdown in relationships with staff); conceptions of success (happiness, improved self-perceptions, learning and progress), factors contributing to success (fresh start/clean slate; home–school communication; pastoral support, school suitability) and problems arising (moving a problem, narratives around young people, timing and family stress). The findings are discussed in relation to implications for practice.

纸粉—聚乙稀复合材料的制备与性能

以马来酸酐接枝聚丙烯为偶联剂,利用双螺杆挤出机一次反应制备了纸粉—聚乙烯复合材料,并用偏光显微镜、毛细管流变仪和其它手段研究了HDPE基-纸粉复合材料的表面形貌、流变性能及其尺寸稳定性和防潮能力。结果表明,添加20%的纸粉,并用相对于纸粉含量30%的偶联剂处理填料,可制得加工性能较好的复合材料,复合材料较原木具有较好的防胀效率和抗吸水效率。     

一类四次系统幂零中心焦点判定与极限环分支

研究一类原点为幂零奇点的四次系统的中心焦点判定与极限环分支问题。对一类四次系统给出了计算原点拟Lyapunov常数的递推公式,且在计算机上用Mathmatica软件推导出该系统原点前10个拟Lyapunov常数,进而分别推导出原点为中心和最高细焦点的条件,并在此基础上得到了此系统的扰动系统在原点充分小的领域内恰有10个包围初等结点的极限环的结论。     

论劳伦斯的“血性意识”

“血性意识”是英国作家D·H劳伦斯的基本性观念。其主要涵义是反对理性对性爱的干涉,追求灵肉和谐结合、“星式均衡”的男女两性关系。劳伦斯从性这一特殊角度批判了资本主义工业文明对人性的扭曲,并探索建立自由健康的男女两性关系。但是劳伦斯所谈的灵肉合一,星式均衡是抽象的,没有触及到资本主义社会的本质,因而批判是乏力的。而他大量赤裸裸的性描写则是非常具体的,有很大的负面作用。特别是他想通过改善男女关系进而改良社会,更是本末倒置。     

Response and interventions into harmful sexual behaviour in schools

Internationally young people report experiencing sexual abuse and violence within schools. Developments within the field of adolescent sexual harm are increasingly recognising the need for ecological approaches to harm. Yet, to date, interventions with young people displaying harmful sexual behaviours have prioritised individual behaviours and characteristics over place-based interventions.This article presents empirical evidence from a mixed-methods study aimed at understanding the enablers and barriers to preventing and responding to harmful sexual behaviour in schools. Research was carried out in seven schools and four multi-agency partnerships in England, UK. Using evidence from focus groups, observations, case reviews and policy analysis the article outlines nine components that enable, or are barriers to, effective responses and interventions into harmful sexual behaviour in schools. The paper concludes that responses and interventions into harmful sexual behaviour must move beyond responding to individual behaviours to intervening within factors within schools themselves.
