简介:110最早是设在刑侦部门的报警电话,功能单一,不为人熟知。1990年左右,福建漳州公安机关提出“有警必接、有难必帮、有险必救、有求必应”的承诺,简称“四有四必”,广大群众这才知道,有困难可以找民警,警察服务于民的色彩开始显现起来。1996年,公安部将“四有四必”推向全国,“四有四必”成为公安队伍一块响当当的品牌。然而,今年1月10日浙江嘉兴市警察却悄悄揭下了悬挂在嘉兴市公安局110指挥中心的“有警必接、有难必帮、有险必救、有求必应”的标语牌。这是浙江省警方首次明确撤销110报警服务台“四有四必”承诺。对此,舆论议论纷纷,广大群众怅然若失。

简介:弟子有点“狂”未必都是过9月25日,《北京晨报》发表蔡辉的同名文章指出:近日.某大学硕士研究生在微信朋友圈中发布了一些批评学界前辈学术能力的言论,其导师斥其为狂徒,并以一封公开信,宣布“断绝师生关系”。评价前辈学术成就,确应谨慎.毕竟学问是一代代层积而成.必有“后见之明”.站在今天的立场上看前人,易产生不过如此之感,这就要历史地、具体地去看问题,学问上没有永远的大师,大家都是后来者的炮灰.正所谓长江后浪推前浪,应该做到“愿长相亲不相鄙”。但.少年轻狂,从来难免,一味压制、威服,未必就是好办法。弟子做得不好,导师可以用自身的好榜样去感化、规劝他.不应采取这么轰动的方式。读书人心中的专制,有时更可怕.因为完全不允许异己存在,该事件中的导师,想必不至于偏狭。
