Education,gift and reciprocity: a preliminary discussion

This paper analyzes the importance and role of the reciprocity relationship in education. It presents a review on the mobilization of the principle of reciprocity—in the anthropological but also sociological and economic senses—in educational processes, especially in adult education. The study is divided into three parts. The first part analyzes the importance of reciprocity in education according to Mauss and to the theory of reciprocity. The second part discusses recent contributions on the role of reciprocity relationships in adult education, expanding Piaget’s perspective on the relation between autonomy and cooperation in education and learning. The third part illustrates this approach with three case studies in Brazil.     

城市贫困人口社会救助方式选择的反思

九十年代,政府开始在城市实施居民最低生活保障制度,其中上海、大连、厦门等城市的经验受到重视,被称作模式来加以推广.对这几种模式的共性和差异进行分析可看出,城市贫困救助普遍面临着救助对象不确定、救助手段单一、经费来源无保证、救助申请制度不健全等诸多问题,而且已经影响到救助行动的开展.因此,现阶段应对全面实施最低生活保证制度取慎重态度,对该项制度的基本问题应有一个较长远的回答,如此,才能确保贫困救助的健康稳健发展.

信息弱势、信息援助与城市农民工社会融入

中国城市农民工已达1.6亿,但他们难以融入城市社会。社会融入不仅是社会经济问题,也是信息问题。对天津市和重庆市566名农民工的调查表明,城市农民工是信息弱势群体,缺乏现代信息交流工具和能力,信息缺失是其融入城市的巨大障碍;现代信息交流工具和信息渠道对城市农民工社会融入有显著影响。因此,公共图书馆应从服务、信息检索培训和提供公共信息设施等方面对其开展信息援助,促进其社会融入。

Family poly-victimization and cyberbullying among adolescents in a Chinese school sample

The sustained increase in their use of social networking facilitates the development of adolescents but comes with the risk of cyberbullying, which creates new challenges in regard to adolescent protection. Past evidence shows that family victimization may play an essential role in the way adolescents learn cyberbullying behaviors. Yet, research on the co-occurrence of family victimization and cyberbullying is limited. This study aims to investigate the associations between cyberbullying and family victimization among adolescents, and to examine the health correlates of cyberbullying and family poly-victimization. A large sample of 18,341 students, aged 15–17, from six cities in China, collected between 2009 and 2010 is employed in the present study, which investigated the association between various kinds of family victimization and adolescent cyberbullying. Data analysis was conducted in 2017. In-law conflict, intimate partner violence, elder abuse and neglect, and child maltreatment were associated with a higher possibility of children becoming internet victims. Parents’ divorce and separation, low family income, mother’s low level of education, and father’s unemployment were all associated with cyberbullying victimization. Cyber victimization was positively correlated to symptoms of PTSD and depression, self-harm, and other physical and mental health variables. Possible explanations for the relationships found in this study are discussed and implications for future research and services are provided. Proactive screening for family poly-victimization and cyberbullying is suggested. Schools are highly recommended to cooperate with parents to promote cyber safety.

短跑的助力训练和阻力训练

如何提高短跑跑速的问题,长期困扰短跑教练员。国际田联生物力学课题组研究的结果表明,超级短跑运动员和普通短跑运动员的最大区别在于伸髋速度,超级短跑运动员伸髋速度极快,明显高于普通短跑运动员。这一研究成果提示我们,发展短跑速度应从髋部做起。助力训练和阻力训练能提高髋部的速度和增强髋部肌肉力量,怎样使这些训练手段更具有针对性,共商榷。     

基于激发态的等谱势的研究

超对称性量子力学中的趋势可以利用激发态来生成，得到广义超对称形式。利用势垒贯穿的观点和方法，可以证明定域势上的解是独立的，即SUSY-m伴侣势是具有m 1个互相独立的定域势的集合。
