3G数字图书馆信息服务模式的构建

随着3G的普遍应用,3G数字图书馆信息服务越来越引起人们的重视。3G网络下的数字图书馆将在服务内容、服务理念以及服务模式等方面做出突破以往的重大变革,图书馆服务也将向更高质、更高效、更个性化和更人性化方向发展。随着3G技术日臻完善以及网络建设的规模化的提高,3G手机用户也与日俱增,加之我们不断改良其带宽性能,无线网络大有替代传统网络的趋势,因此现代的数字图书馆开展3G服务具有广阔的发展前景。     

数码产品的视觉建构与文化表征

数码产品作为承载、展示、传递数字信息的物质载体,在视觉建构上具有重视外观审美、以互动界面连接不可见的内部信息和可见的外部结构以及通过创造“虚拟环境”来引发全新的视觉体验等特性,不仅形成了视觉吸引力,而且深化着人们对数字化世界的凝视、感知与依赖.同时,作为数字化世界的物质文化符号,数码产品还表征了新电子表现主义、信息化生活方式和科技消费潮流等文化现象,传播了数字化生存方式的文化意义.在以视觉为主导形式的社会中,数码产品是一个集艺术性和技术性为一体的视觉文本.     

符号学理论视野中纪实摄影的真实性分析

我国对纪实摄影本体论和真实性的研究,很少从符号学分析入手,忽略了符号学语境下所潜藏着的价值。依据符号的直觉性、二重性、情感性和主观性,对纪实摄影视觉图像符号的真实性进行研究和探讨。     

媒介融合背景下我国数字内容的监管难题与解决路径

媒介融合背景下我国数字内容出现了三大监管难题:数字内容的监管模式选择问题,数字内容的监管失控问题以及数字内容的监管权属问题,造成这些问题的主要原因是网络融合使传统的分类监管难以适应传播管道的一体化形势、终端融合使传统的源头控制失效导致内容失控,内容的融合产生交叉业务导致监管权属之争;借鉴西方国家的经验,遵循媒介本身的监管规律,解决我国数字内容监管难题的的基本路径是:通过立法统一监管体系,确立数字内容的监管标准,强化媒介的中、后端监管,尝试综合型的内容监管模式.

Totalitarian Paranoia in the Post-Orwellian Surveillance State

Most commentary on the Edward Snowden affair and other recent accounts of government spying leaked in the media has focused on individual privacy concerns, while overlooking how contemporary neoliberal modernity has created a social order in which new surveillance technologies grant the state a degree of power unthinkable to past generations – exceeding in reach and complexity even the totalitarian state imagined in Orwell's dystopian account, 1984. Any critical analysis of the modern surveillance state must move beyond documenting abuses of state power to address how government repression has been allowed to proceed unchecked, and even to flourish, through its support of an antidemocratic public pedagogy produced and circulated via a depoliticizing machinery of fear and consumption. In the USA, repression works through the homogenizing forces of the market as well as a corresponding loss of public memory and political identity to encourage the widespread embrace of an authoritarian surveillance culture. The state and corporate cultural apparatuses now collude to socialize everyone into a surveillance regime, even as personal information is willingly given over to social media and other corporate-based sites as people move across multiple screens and digital apparatuses. It is no longer possible to address the violations committed by the surveillance state without also analysing this broader regime of security and commodification. The authoritarian nature of the corporate–state surveillance apparatus in the USA can only be fully understood when its ubiquitous tentacles are connected to wider cultures of entertainment, commerce and punishment, and the increasing labelling of democratic dissent as an act of terrorism. If democracy is to have a future in America, then it is imperative to organize social movements capable of recovering public memory and reclaiming dissent as essential features of responsible citizenship.     

Teenagers' Multisensory Routes for Learning in the Museum

ABSTRACT

In this article I draw on a study of sensory aspects of teenagers' use of digital media, how these sensory aspects are incorporated in emerging learning strategies, and the implications of this for the same teenagers' engagement in museums. My focus is on how an ethnographic approach that attends to the senses may enable a critical review of prevailing pedagogical ideas in museums. Recent developments in museum education have led to large investments in state-of-the-art technology to produce interactive, multisensory exhibits. However, the question of how teenagers respond to these campaigns remains rather under-researched. This article shows how habitual use of digital media in teenage everyday practice incorporates learning to appropriate other people's experiences and ideas through a configuration of vision, touch, motion, and imagination, thereby enhancing non-representational learning qualities such as affect and sensation. The implications of this sensory approach open up routes to differentiate pedagogical settings in museums that on a superficial level apply the same educational technologies, but since they are based in different sensorial belief systems, different conditions for learning unfold in their use. In developing this analysis I argue that through ethnographic attention to the senses we might advance theories of learning within museum education.
