从翻译美学视角看《红楼梦》中隐喻人名英译

作家给人物命名从来不是随心所欲,人物命名通常隐含深层寓意,红楼梦人名不仅寓意深刻,而且蕴含着丰富的美学信息,两个译本的人名翻译也各有千秋。从翻译美学角度着手,以红楼梦中隐喻人名为审美客体,可以对原文中人名的美学价值和译本中的美学信息加以分析。通过对译本采用的翻译策略作一分类,并分析在还原原文美感方面的得失之处,可知在隐喻人名翻译中,只有充分体会原文美感并对其进行还原或补偿,才能在译文中尽可能多地保留原文的韵味,达到神似。     

高校更名的理性思考

前几年高校如火如荼的合并、升格,带来了高校大规模的更名之风。尽管近年来高校更名之风得到了有效控制,其更名也符合高等教育改革发展的逻辑和规律,但一些高校更名求大求全、热衷虚名、追求时髦、缺乏特色,一定程度上影响了学校的质量和声誉。因此,高校更名要名实相符;教育行政部门要制定标准,严把更名关;社会对高校的评判要客观,不能＂以貌取人＂,只有这样,才能使高校更名回归理性,突出特色。     

The changing functions of citation: from knowledge networking to academic cash-value

This essay reviews the changing functions, and effects, of citation systems in scholarly research as they move from a range of uses primarily oriented around knowledge networking and epistemic validation, to their use as a set of metrics oriented around evaluating and rewarding certain kinds of academic performance (e.g. “impact factors”). It is argued that this shift of emphasis has a distorting effect on the uses of citations, and that the more important these metrics become, the more distorting it is. Specifically, it is argued that rewarding certain kinds of citational practices leads to “gaming” the system: this makes the use of these metrics actually less reliable – and in some cases counterproductive – and leads to what in the author’s view are self-serving and sometimes unethical behaviours.     

湖南侗语地名的语言结构及命名理据探析

湖南侗语地名不仅记录了侗族人对其聚居地的地理环境的认知和分类,也蕴含了丰富的语言、历史、文化信息。湖南侗语地名在语言结构上采用侗语偏正式结构特有的"通名+专名"结构,在命名理据上,通名主要以自然地理实体特征、人工建筑物或设施、聚落或行政区划等命名;专名主要以动物、植物、方位、地形特点、民族、姓氏名等命名。     

异步传输网络的频域分块频谱估计算法

异步传输网络间通信信道组成复杂,对异步传输网络间通信信道的频谱的准确估计可以避免不占用多余的频带,能够实现高数据率通信。提出一种基于频域分块和脉冲响应的异步传输网络频谱估计算法。构建异步传输网络通信信道模型为缓慢时变、空变的相干多途信道,采用正交频率复用OFDM训练序列得到确定的起始帧概率分布,采用同步算法能有效减少系统子载波间的正交性抑制,得到系统函数的基本特征传递函数,实现对频域分块频谱估计。仿真结果表明,该算法能有效提高对频谱的估计精度,提高异步传输网络的通信性能,网络异步数据传输的吞吐量大幅提高。     

Search history support for finding and using information: User interface design recommendations from a user study

Recording search histories, presenting them to the searcher, and building additional interface tools on them offer many opportunities for supporting user tasks in information seeking and use. This study investigated the use of search history information in legal information seeking. Qualitative methods were used to explore how attorneys and law librarians used their memory and external memory aids while searching for information and in transferring to information use. Based on the findings, interface design recommendations were made for information systems.     

完全匹配吸收边界在多层介质中的研究及应用

基于有限差分时域有限差分方法的递归算法的时间和空间来设置完全匹配层(PML)的吸收效应的推导和分析。试验结果证实,PML在多层介质中具备优异的吸声性能。最后,在FDTD算法的PML吸收层是用来模拟在两层和三层介质模拟区。PML的有效性的验证。     

论纪昀的乡恋情结--《阅微草堂笔记》的主体情感之一

恋乡情结是每个人都会有的情感体验.纪昀自离开故乡沧州后,因事务萦身,四十余年未曾归乡,但他并没有忘记故乡.通过对<阅微草堂笔记>中其所记故乡地名、人物、事件的归类分析,我们可以看出,他那种心系乡里、落叶归根的故乡情结,至老弥显、至老弥坚,显示出他富贵不忘根的君子品格.     

Complicating moral messages through multimodal composition: wrestling with revenge and racism

This study is an exploratory analysis of the multimodal composition practices of adolescents and young adults in a free after-school drop-in programme called the Workshop, and the moral development opportunities afforded by these practices. Pasupathi and Wainryb’s [(2010). “Developing Moral Agency Through Narrative.” Human Development 53: 55–80. doi:10.1159/000288208] theory of narrative moral agency is invoked to interpret participants’ compositions. Through a process of multimodal design, participants illustrated the cognitive process of reconciling one’s moral beliefs with actions in the real world. Switching between modes of expression allowed the focal participants to showcase their nuanced moral positions on justice-related issues, such as complicating a desire for revenge with advocating for peace. The literary, technological, and performance opportunities of the Workshop serve as an example for how social, aesthetic, and moral goals can be achieved in classrooms and contribute to students’ moral agency.
