Hilbert C~*-模上的算子值框架及分解

已知A是含单位的C*-代数,在文中仅在标准模HA=l2(A),以及其子模H0上讨论,主要给出了判定某序列{Aj}j∈J B(HA,H0)是算子值框架的一个等价命题,以及利用算子理论中有关算子的分解,从而得到框架的相关分解的命题.

Examining the public face of academic development

Language is an important way of presenting an identity, either individual or group. This paper explores the language used in the presentation of the identity of academic development. The study is based on an analysis of websites from academic development centres in the UK and Australia and outlines the public ways in which academic developers present their work and the meanings that are attached to this presentation. It uses frame theory to analyse the language of academic development websites in order to explore some of the assumptions underpinning the public face of academic development. It explores the ways in which language is used to frame and persuade in order to establish the credibility of academic development as an expert and scholarly field.     

“概论”课实施“理论框架教学专题讲座教学”新模式的设想与实践

“概论”课本身的理论框架是该课程的重要教学内容之一。“概论”课教学应该将每章内容的理论框架给学生讲清楚。在专题讲座教学方面,可以把“概论”课教学设计成十四个专题。无论是理论框架教学还是专题讲座教学都需要教师多下功夫。专题讲座教学需要教师具有一定的亲和力和良好语言表达能力,专题讲座教学要注重情感沟通。

北京话旁称代词的历时嬗变（1750—1950）（上）

自18世纪中叶到20世纪中叶,北京话旁称代词系统在句法、语义上呈现出了比较明显的发展变化,这种发展变化在三个时期的三部典型的北京话文献《红楼梦》《儿女英雄传》《正红旗下》中得到了充分的反映。就旁称代词系统而言,历时嬗变的发生轨迹是：由18世纪中叶的＂别人、人家、别人家、他人、旁人＂阵容切换到了19世纪中叶的＂人家、别人、他人、旁人＂阵容,并最终切换到了20纪中叶的＂别人、人家＂阵容,期间的此消彼长、删汰整合昭然。就旁称代词个体而言,历时嬗变的发生轨迹是：1.＂别人＂由18世纪的炙热到19世纪的没落,再到20世纪的重新走强;2＂.人家＂由18世纪的初露锋芒到19世纪的首度大大超越＂别人＂而一枝独秀,再到20世纪与＂别人＂的平分天下;3＂.他人＂这个曾经在相当长的时段内的旁称代词家族的宠儿由18世纪的颓势已现到19世纪的英雄末路,直至20世纪的难觅踪影;4.不温不火一路走来的＂旁人＂由18世纪的衰落到19世纪的走向没落,直至20世纪的淡出我们的视线;5.产生于元代的＂别人家＂由18世纪的衰弱到19世纪的没落,直至20世纪的只留存在部分方言中而在北京话中彻底消亡。     

An Insidious Poison or a Door to the Story?

The aim of this paper is to grasp the influence of the newsroom on frame-building processes. First, journalists’ own understanding of “frames” and “framing” is discussed. Second, from an academic interpretation of these concepts, journalists’ framing practices are studied. To this end an ethnographic study was conducted at two newsrooms, one in Belgium and one in the Netherlands. The findings reveal that while the noun “frame” is sporadically used as a tool, the verb “framing” is considered as something from which a journalist should refrain. This is explained by the associations journalists make with strategic framing from sources as well as by the newspapers’ explicit attempt to no longer view the world from a single ideological frame. It is argued that the studied newsrooms have replaced ideology by, respectively, a counterframing strategy that strives to disprove existing frames (deframing) and a narrative approach that, one the one hand, sharpens existing frames but, on the other hand, offer more opportunities to create alternative frames (reframing) for events.
