《诗经》毛传“某,某;某,某也”形式之义隔相训初探

后世对于《诗经》毛传的研究可谓非常细致了,对单音词的研究却不多,对单音词相训中的＂某,某;某,某也＂这种特定形式的研究则更少。这种单字相训的形式在毛传中是很普遍的,从意义远近的角度来讲,被训释词和训释词可以有义同相训、义近相训、义隔相训及义反相训等不同的类型。文章从义隔相训入手,对训释词与被训释词从引申关系、假借关系的角度进行了分析。     

词的本义和引申义关系探微

汉语中有很多一词多义的情况,它使语言的表达丰富多彩,能更好地满足交际的需要。词义引申是形成一词多义的根本原因。词的引申义是指词义发展过程中由本义通过多种方式派生出来的意义。引申义和本义间有各种联系方式,归纳起来主要有相似引申、相关引申、相因引申。     

终身教育思想的新实践:英国的拓展学校

英国的拓展性学校是指学校在正规的教学时间之外提供系列服务和活动,以满足学生、家长和社区的需要。拓展性学校解决了儿童无人监管的问题和社区教育薄弱的问题,具备关心儿童当下生活,关注弱势群体,整合社会教育资源的特点,契合了终身教育的精髓,为各国的学校教育改革提供了借鉴。

Social worlds and religious education in Poland: towards the elimination of disharmony

ABSTRACT

The goal of this article is to present the coherence between the human social world and religious education in Poland. The motive for taking up this subject is the cultural context relating to the problem of attitudes towards refugees. Reconstruction of the worlds of life demands to be expanded to include the religious education context in order to adapt the education practice to the requirements and expectations of the social environment. This has been achieved based on secondary analysis of the source texts (pedagogical, sociological and theological) and existing research results, which refer directly to the practice of lifelong religious education and concern applications in the area of shaping social competences and the developmental effort of Polish thinking and understanding. These include: (1) Dissemination of the pedagogical category of decentration; (2) Resignation in the practice of religious education from universalistic apriority and realistic ontology, and the implementation of hermeneutics of understanding to religious education and a new model – supra-confessional, pluralistic model open to the knowledge of other religions and beliefs systems; and (3) Develop competences for an internal dialogue. For the practice of lifelong learning, this means abandoning the alienated learning culture and carrying out this process within the community.     

改进粒子滤波在被动目标跟踪中的应用

As a new method for dealing with any nonlinear or non-Ganssian distributions, based on the Monte Carlo methods and Bayesian filtering, particle filters （PF） are favored by researchers and widely applied in many fields. Based on particle filtering, an improved extended Kalman filter （EKF） proposal distribution is presented. Evaluation of the weights is simplified and other improved techniques including the residual resampling step and Markov Chain Monte Carlo method are introduced for target tracking. Performances of the EKF, basic PF and the improved PF are compared in target tracking examples. The simulation results confirm that the improved particle filter outperforms the others.
