基于视觉模型的双正交小波图像水印算法

提出了一种基于人类视觉系统模型的双正交小波多分辨图像水印算法,该算法充分利用小波多分辨的优点及人眼视觉系统的特性,保证了水印的不可见性及鲁棒性,同时在检测水印时也不需要原始图像,仅需涉及到相关的几个细节子图。实验表明该水印算法对于中值滤波、叠加加性噪声、JPEG有损压缩三种图像处理都是鲁棒的。检测算法还有计算量小,检测速度快的特点。     

THE PARTICIPATION DIVIDE: Content creation and sharing in the digital age

This paper looks at the prevalence of creative activity and sharing in an age when the barriers to disseminating material have been considerably lowered compared with earlier times. The authors use unique data to explore the extent to which young adults create video, music, writing and artistic photography, as well as the prevalence of sharing such material online. Findings suggest that despite new opportunities to engage in such distribution of content, relatively few people are taking advantage of these recent developments. Moreover, neither creation nor sharing is randomly distributed among a diverse group of young adults. Consistent with existing literature, creative activity is related to a person's socioeconomic status as measured by parental schooling. The novel act of sharing online, however, is considerably different by gender with men much more likely to engage in it. However, once internet user skill is controlled for, men and women are equally likely to post their materials on the Web.

在数字图书馆建设中要认真学习领会知识产权法 ,科学地解决在数字图书馆建设中所面临的知识产权问题 ,既要寻求法律保护 ,也要积极采取新技术手段。建议在修改和完善知识产权法时 ,赋予图书馆对馆藏文献的数字化权、展示权和出借权     

Attracting Micro‐Enterprises To Learning

Micro‐enterprises, i.e. firms with less than 10 employees, are traditionally the hardest to engage in learning; they are also least likely to participate in such measures as business advice and guidance provision and initiatives to support information communication technology (ICT) adoption. Through a community‐based initiative initially targeting parents (unemployed or employed) to participate in ICT, 30 micro‐enterprises were attracted to learning for the first time. These companies had carefully avoided similar initiatives taking place locally, which emphasized business success and growth; they had only participated in this ICT skills training because of their children. The paper takes a case study approach to evaluate the reasons for participation, explores barriers and implications for those organizing similar activities, and calls for a more holistic view of owners and managers of small firms as fathers, mothers, etc. rather than just as ‘entrepreneurs’.     

Changing Gender: The Discursive Construction of Equal Opportunities

This article provides a discursive perspective on the dilemmas of sameness and difference feminisms and their consequences for change projects. It explores how equal opportunity officers dealing with gender issues and introducing equality legislation in practice construct the meaning of equal opportunities. The analysis of the interpretative repertoires and ideological dilemmas drawn upon in ten interviews shows the highly context‐specific use of four different repertoires constructing gender equality: the sameness, difference, bandwidth and deconstructive repertoire. Interpreting the shifts between repertoires from the perspective of the ideological dilemma, new avenues for change are explored. The article concludes that the simultaneous use of all possible theoretical perspectives might be a worthwhile objective.     

“数字鸿沟”：当代社会阶层分析的新视角*

当代社会，随着信息技术的发展以及信息重要性的增强，以互联网等为基础的电子信息网络已经浸透于社会的各个领域之中，在产业、经济和社会中生成着一种新的信息场域，影响着人们的社会生活。本文从社会阶层的研究视角出发，透过“现代——后现代”的二维分析模式对信息及信息技术带来的“数字鸿沟”现象进行理论上的阐释，对其究竟是实现着“阶层化”还是“去阶层化”进行探讨，并对信息化高度发达的日本社会进行了“数字鸿沟”的实证分析。可以看出：信息、信息技术已经成为一种新的变量，并与社会阶层之间产生着密切的关系，重塑着社会阶层化机制。     

陌生化与数字艺术的审美价值

陌生化理论对于突出艺术自身的审美价值还是有着重要的指导性意义,特别是对于数字艺术,由于其交互性、虚拟性和可复制性等特征,欣赏者容易陷入一种艺术与现实混沌不分的数字沉迷状态,奇观化、戏拟和拼贴等陌生化艺术程序成为数字艺术实现审美价值的重要艺术形式。     

数字技术对文化产业内容生产的挑战及其应对策略

数字技术当前深度参与文化产业的内容生产,对创作群体、生产活动、传播形式和消费语境等多方面皆产生重大影响,形成了全新的数字文化产业生态。然而,有些数字文化产品过于强调技术而忽视文化的特殊性,导致出现内容生产粗糙随意、价值判断标准矮化、意识形态风险增加等问题,不能稳定地输出品位高、社会效益佳的文化产品,未来发展面临挑战。对此,数字文化产业的内容生产需要打破“注意力经济”的单一模式、改良人工智能算法的激励与推荐机制、探索文化生产评价标准的自我更新,从而推动新时代数字文化产业的高质量发展。
