微博在中国的互联网上十分流行,这对中国宣传机构的信息控制形成了新的挑战。微博可以使信息得到快速和广泛的传播,从而增加了国家宣传机器进行信息控制的难度。本文试图探讨微博可以在多大程度上帮助网民挑战政府对信息的控制。通过分析在新浪微博上收集的数据,本文发现微博对宣传工作的挑战有四种机制。首先,基于对微博上热门政治信息的分析,本文发现微博上的部分话语权由媒体转向个人,同时出现了一批对政府持批判态度的超级网民。其次,对于一些热点事件,微博与传统媒体的报道角度与侧重点不同,从而使得中国的政治信息更加多元化 。第三,虽然中央政府可以实现对微博的有效审查,但地方政府时常不能控制微博上的报道。第四,网民通过微博上的信息运动,可以将某些传统媒体不愿报道的事件问题化,这对中国传统媒体的自我审查形成了冲击。本文认为微博可以帮助人民挑战国家的信息控制。 ; The micro-blog, with its huge popularity in recent years, poses a new challenge to the propaganda state in China. The micro-blog is able to spread information fast and reach a wide audience. The liberating potential of the micro-blog on the information flow is in conflict with the control efforts from the propaganda state. It is puzzling then the extent to which the netizens are able to use the micro-blog to counter the information control. Based on the data collected from Sina Weibo, this study finds the propaganda state is challenged by the micro-blog through four mechanisms. First, analysis of political posts demonstrates a partial shift of discursive power from media to individuals and a rise of critical super-netizens in the micro-blog. Second, the posts in the micro-blog report the controversial issues in a different way than the traditional media that contributes to the pluralization of political information. Third, the netizens are able to use the micro-blog to expose certain information that the local government would like to censor. Forth, the netizens are able to problematize certain issues through information movement that challenge the self-censorship of media. This study concludes that the micro-blog is able to empower the people in the battle between state and society on what is fit to know. ; Detailed summary in vernacular field only. ; Yang, Shen. ; Thesis (M.Phil.)--Chinese University of Hong Kong, 2013. ; Includes bibliographical references (leaves 94-98). ; Abstracts also in Chinese. ; LIST OF TABLES AND FIGURES --- p.VI ; Chapter CHAPTER I. --- INTRODUCTION --- p.1 ; Chapter 1.1 --- INTRODUCTION --- p.1 ; Chapter 1.2 --- ...

Social media is changing the business of representation in the Senate. If you want to know what your senator is up to, you don't need a newspaper, just your phone. Drawing on a unique dataset of almost 200,000 senator tweets, Tweeting is Leading offers a critical analysis of senators' communication on Twitter, the individual and constituent forces that shape it, and the agendas that result.

"Political aspects" that enhance, but also undermine, the positive transformational power of public innovation policies are examined. As such, this paper follows Michał Kalecki in his 1943 paper that identifies the "political aspects" which enhance and undermine the positive transformational power of Keynesian full employment policies. Similarly, this paper provides a policy framework that identifies what government and business support as innovation policies. The role of innovation stems from Schumpeter's long-run perspective, but incorporates the more dynamic cyclical short-term and trend perspectives of Kalecki. This paper critiques the strategy of public innovation policy in general and derives policy implications. © 2009 Elsevier B.V. All rights reserved.
