Rethinking mediated political engagement: social media ambivalence and disconnective practices of politically active youths in Hong Kong

Social media have been widely credited for facilitating young people’s political engagement, most notably by providing a conducive platform for political expression. There has been comparatively little attention, however, to the possible pitfalls for young people when they engage in politics on social media. In this study, we seek to redress the overemphasis on the strengths and connectivity of social media by attending to how young people negotiate their drawbacks and disconnectivity. Through in-depth interviews with young participants of Hong Kong’s Umbrella Movement, we examine the choices and motives regarding mediated (non-)participation among a group of politically active youths. Our findings revealed that these young people’s social media ambivalence emerged from the major participatory experience. Despite their active and open informational sharing and political expression on social media alongside their in-person participation during the eventful protest, many young participants became wary of such expressive use owing to their perceptions of de-energization, disconnectedness, and disembodiment. Instead of completely withdrawing from political activities on social media, these politically inclined and technologically savvy youths embraced “disconnective practices” – passive engagement (lurking), selective expression (moderation and exposure-limitation), and offline participation (embodied collective action) – to avoid the overwhelming, fractious, and inauthentic conditions of mediated participation.     

ICT投资、互联网普及和全要素生产率

本文使用DEA-Malmquist指数方法对2002-2012年我国分行业全要素生产率、技术效率与技术进步进行测算,并基于我国地区投入产出表构建了ICT资本投入强度。在此基础上,本文就ICT投资对生产率的影响进行了实证检验。研究发现,ICT投资对全要素生产率提升具有积极作用,并且主要通过ICT投资促进技术效率提升实现。面板门限回归模型的结果显示,只有达到一定互联网普及率时,ICT投资促进技术效率提升的作用才显现,并在高互联网普及率时进一步增强;但在高互联网普及率下,ICT 投资对技术进步存在抑制作用,在全要素生产率层面表现为ICT 投资的促进作用消失。因此,现实的ICT 投资应重视通过信息化管理提升行业资源的有效利用能力,以最大化技术效率对全要素生产率的贡献;应充分考虑不同行业和地区的互联网普及程度,以深度激发“连接经济”对于释放ICT效能的互补性作用;还应注意配套相应产业政策,以减轻互联网发展对技术进步的阻碍作用。     

Evaluations of FDR-controlling procedures in multiple hypothesis testing

Many exploratory experiments such as DNA microarray or brain imaging require simultaneously comparisons of hundreds or thousands of hypotheses. Under such a setting, using the false discovery rate (FDR) as an overall Type I error is recommended (Benjamini and Hochberg in J. R. Stat. Soc. B 57:289–300, 1995). Many FDR controlling procedures have been proposed. However, when evaluating the performance of FDR-controlling procedures, researchers are often focused on the ability of procedures to control the FDR and to achieve high power. Meanwhile, under the multiple hypotheses, it may be also likely to commit a false non-discovery or fail to claim a true non-significance. In addition, various experimental parameters such as the number of hypotheses, the proportion of the number of true null hypotheses to the number of hypotheses, the samples size and the correlation structure may affect the performance of FDR controlling procedures. The purpose of this paper is to illustrate the performance of some existing FDR controlling procedures in terms of four indices, i.e., the FDR, the false non-discovery rate, the sensitivity and the specificity. Analytical results of these indices for the FDR controlling procedures are derived. Simulations are also performed to evaluate the performance of controlling procedures in terms of these indices under various experimental parameters. The result can be used to summarize as a guidance for practitioners to properly choose a FDR controlling procedure.     

主体间性视阈下交往行为的合理性与和谐社会建构

"主体间性"是胡塞尔的现象学和哈贝马斯的"交往行为"理论的重要概念。文章通过梳理概念的来龙去脉,揭示了自我、主体、主体性、主体间性与交往行为等概念在不同哲学背景下的不同意涵与内在关联,进而把主体间性视阈下交往行为的合理性与和谐社会的建构联系起来,论证了主体间良性交往是通达和谐社会的必要条件。

翻译学从属于语言学吗？——析语言学派的翻译学定位

翻译理论研究能走上系统化、科学化和客观化的道路,在很大程度上得益于语言学的发展。不过,语言学派翻译研究者大多把翻译研究纳入语言学或应用语言学的范畴,这一做法不能全面反映翻译学科的根本性质。这种范式体现出单纯精准科学化的片面性,在翻译研究中并不完全适用。把人文科学中并不稳定的客体当作相对稳定的自然科学的客体来看待,在较大程度上抹煞了人文科学与自然科学的差异性,使翻译研究成了一种程式化的规律研究。翻译实践不是一般语言活动,而是双语转换活动,是一种人文性极强的实践活动。研究翻译实践活动的翻译学是一门与语言学、文艺美学、文化研究及信息传播学等学科相平等的独立的人文学科。     

论林黛玉是《红楼梦》的轴心人物

《红楼梦》是我国古典小说的巅峰之作,其巅峰性不仅表现在它在人物、情节、环境、语言和主题意蕴诸方面都达到了中国文学的艺术至境,而且还表现在它的无与伦比的"奇妙性",其最大的"奇妙"处不是别的,而是用一个人物"扛鼎"起红楼梦世界,这个人物就是林黛玉。《红楼梦》的轴心人物不是贾宝玉、薛宝钗、史湘云、王熙凤,而是林黛玉。作者特意赋予林黛玉许多奇特的禀赋,如"草"、"神女"、"玉石"、"花神"、"帝妃"、"玄珠";"报恩"、"情恋"、"乡愁"、"诗性"、"本真"等,使她成为一个全局化的"结构轴心",目的是要在整体上为其"为史作传"的新人学建设提供一个"一而统万"的"阿基米德点"。与之配套的是小说人物的"立体幻影互文结构",它保证了林黛玉"轴心论"的有效实施、贯彻。林黛玉是中国历史上"新人学"范型的一次辉煌而壮丽的日出!她的神奇之光完全可以与西方现代、后现代的"美学人学"共契圆舞,交相辉映!她是中国的维纳斯、海伦和贝亚德丽齐;是中国近世人学拯救的人格化的诺亚方舟。     

《小城三月》的文化内蕴

萧红的《小城三月》以悠扬婉转的笔调叙述了一个凄婉的爱情故事。小说中翠姨与"我"的堂兄的爱情悲剧既是性格悲剧,更是新旧文化冲突所导致的悲剧,是生命之花在"五四"新文化春风的吹拂下灿然绽放、却又在传统文化的重重裹挟下悄然萎谢的悲剧。这悲剧凝聚着萧红自身深切的生命体验与深沉的文化思考。
