Perspectives on the right to publish: Globalinequalities, digital publications, and thelegacy of revolutionary France

By 1789 the French Enlightenment had alreadyestablished that the rights of citizensincluded the right to speak, write, and printfreely. This right has since been enshrined invarious national and international documents,but remains elusive in much of the world. Oneway to consider these freedoms is to look notjust across the world comparing nations thathave or don't have freedom, but back throughtime at the first effort to promulgate thesenew rights – the French Revolution. When theFrench Revolution created freedom of the pressin 1789, the French book publishing industrywas noted for five attributes: completecensorship of all publications, a rigidlyenforced printing monopoly, copyrightprotection for all authors, fossilized content,and the proliferation of illegal presses. Digital technology is enabling a second dawn ofpress freedoms, but the five problems found inFrance two centuries ago can still be seen invarious forms, especially in the massivemonopoly of book publishing by a few countries. The answers created by France in 1810 present apartial basis for how current governments couldrespond to contemporary problems with freedomof the press. Rightly used, new digitaltechnology also has an opportunity to finallyfacilitate one of civilization's fundamentalfreedoms.     

Now You See Me – Now You Don't: Journalists’ Experiences With Surveillance

If democracy is a platform for many voices, and the voices of the many, journalists serve democracy by bringing these voices to the forefront of governance by asking difficult questions to those in power. It can be argued that journalists engage in the broader form of surveillance of power from below, or sousveillance [Mann, Steve, and Joseph Ferenbok. 2013. “New media and the power politics of sousveillance in a surveillance-dominated world.” Surveillance and Society 11 (1-2): 18–34.], which aims towards a form of relative equilibrium. In democracies, the institutional system of checks and balances forms the basis on which journalism pursues its watchdog function. This paper explores the experiences of journalists with surveillance and their impact on journalists’ sense of freedom to fulfil their watchdog role. The paper contributes to increasing research interest in “journalism after Snowden” by addressing the intangible conditions under which journalists may or should work, and ultimately also how widely accepted standards of democratic liberties are challenged.     

赛时新闻发布的体育公共外交价值研究——基于各国运动员、教练员在北京奥运会新闻服务平台展示状况

传统公共外交向新公共外交转型的重要变化是,行为主体不仅仅是政府,而是包括政府、非政府组织、个人在内的多样化主体.新公共外交强调,在全球化的交往和传播环境下,人人有责任、有条件参与重塑国家形象、增强国家软实力、增进国际间的互信与认同.基于对新公共外交的理解,文章论述了传统意义体育外交的局限,尝试探讨了赛时新闻发布在建构共享价值观、展现个性魅力方面所能产生的体育公共外交价值,这对各国借助大型赛事开展体育公共外交具有启发意义.     

当前藏书建设中存在的高比例误选黑洞及对策——以计算机类图书为例

我国高校图书馆图书误选的比例很高,已经形成可怕的误选黑洞。根据2002—2005年出版的计算机类图书数据测定出核心书目并对照5所综合性大学图书馆的馆藏发现,高校图书馆缺藏现象和零外借率现象十分严重,由此可推断目前高校图书馆存在计算机类图书的高比例误选黑洞。针对这些问题,高校图书馆可以采取分析核心出版社的出版强项、研究好书的形成要素、推动书商编制高质量的征订书目等策略。

魔镜:小说《洛丽塔》的电影之旅

小说《洛丽塔》是一部以艺术技巧见长的名著,其主题的复杂含混给电影改编带来难度,而同名的两部电影改编却挑战了这种难度。1962年的库布里克版以黑色幽默和家庭讽刺喜剧的方式展现了小说中人物可笑荒谬的处境,1997年莱恩版则将同名小说演绎成好莱坞式情爱悲剧故事。两片均在唯美的气息和感伤的情绪上与原著相通。从艺术和审美的角度评判,这是两次成功的电影改编。
