The increasing use of frameworks within which Internet users can contribute nontextual information constitutes a serious obstacle to government attempts to accurately censor and monitor Internet traffic. This development, as seen in the explosive growth of frameworks such as Second Life, YouTube, and Wikipedia, could lead to a transfer of regulatory power away from heavily regulated Internet Service Providers in nondemocratic regimes, into the hands of intermediaries that are more likely to uphold freedom of expression. Thereby, a development toward increasingly enframed and nontextual information can promote freedom of expression even in traditionally nondemocratic regimes. I analyze this development with regard to its possible implications for freedom of expression, online crime, and the role of private companies in international politics.  相似文献

This paper proposes a unified conceptual framework to analyze the multiple role and consequences of patents in the case of biotechnology research tools. We argue that the knowledge/information and independent/complementary nature of research tools define heterogeneous frameworks in which the patent system plays different roles. In particular, using the analogy with the free-libre open source movement in software, we show that patents can promote open innovation by ensuring the freedom of some pieces of knowledge. A strong conclusion of the paper is therefore that, against common belief, an adequate use of the patent system may contribute to preserving freedom of access to upstream research tools within a framework that we call free-libre biotechnology.  相似文献

This study summarizes prior reviews of new media and Internet research, and the growth of the term Internet in academic publications and online newsgroups. It then uses semantic network analysis to summarize the interests and concepts of an interdisciplinary group of Internet researchers, as represented by session titles and paper titles and abstracts from the 2003 and 2004 Association of Internet Researchers conferences. In both years, the most frequent words appearing in the paper abstracts included Internet, online, community, social, technology, and research. The 2003 papers emphasized topics such as the social analysis/research of online/Internet communication, community, and information, with particular coverage of access, individuals, groups, digital media, culture; role and process in e-organizations; and world development. The 2004 papers emphasized topics such as access; news and social issues; the role of individuals in communities; user-based studies; usage data; and blogs, women, and search policy, among others.  相似文献

One of the fastest growing forms of downloadable Internet-based data involves digital map layers that contain spatial features suitable for analysis with a geographic information system (GIS). The availability of networked spatial data has fostered tremendous growth in the importance and use of location-based services, and it is now commonplace to find a wide variety of map-based applications and data sets on the Internet for unrestricted download. Despite the rapid growth in spatial data resources, there has been scant attention paid to their currentness, lineage, locational accuracy, completeness, and overall usefulness. This article discusses the quality of Internet spatial data by taking an extreme case to evaluate both the availability and the usefulness of spatial data posted on publicly accessible Web sites. The case study examined is Tibet, which is selected purposively because it lies at or beyond the fringes of the network society. The issue examined concerns the rehabilitation potential of locatable Buddhist monasteries. In undertaking this assessment, the efficacy of the current Internet as a source of useful spatial data is brought into question.  相似文献

This paper may be read as a sequel to a 1995 paper, published in this journal, in which I predicted what sort of transformations and problems were likely to affect the development of the Internet and our system of organized knowledge in the medium term. In this second attempt, I look at the future developments of information and communication technologies and try to estimate what their impact on our lives will be. The forecast is that, in information societies, the threshold between online and offline will soon disappear, and that once there is no difference, we shall become not cyborgs but rather inforgs, that is, connected informational organisms.  相似文献

Amartya Sen’s capability approach has become increasingly popular in development studies. This paper identifies controllability and operationalisability as two key stumbling blocks which prevent the capability approach from being used even more widely in development practice. It discusses the origins and application of the Choice Framework, a conceptual tool designed to help operationalise the approach. The framework can be used to deconstruct embedded ideologies and analyse the appropriateness of development goals, to map development as a systemic process, and to plan interventions which can result in increased freedom of choice for people. Three examples of the application of the Choice Framework in the field of information and communication for development (ICT4D) are given. The three technologies which are examined, telecentres (Infocentros), Chilecompra and Fair Tracing, can be placed at different places of a determinism continuum, some reducing the spectrum of choices a user has. The paper argues that while frameworks such as the Choice Framework can be developed further to increase the operationalisability of the capability approach, it is up to development funders to accept the fact that people’s choices are never fully predictable and thus Sen’s ‘development as freedom’ will inevitably be a dynamic and open-ended process.  相似文献

What is so bad about Internet content regulation?   总被引:1,自引:0,他引:1  
Legislation was recently introduced into theAustralian parliament to regulate the Internet. Thiscreated a storm of protest from within the computerindustry, where arguments against the legislationranged from those based on technical difficulties tothose based on moral considerations, particularly offreedom of speech and freedom to access information.This paper is primarily concerned with the moralaspects of Internet regulation, but within theparameters of current technology. It will argue thatsuch regulation can be justified, despite the factthat given the current technology there will bedifficulties with enforcement, and reduction inInternet performance.  相似文献

Is there such a thing as information justice? In this paper, I argue that the current state of the information economy, particularly as it regards information and computing technology (ICT), is unjust, conferring power disproportionately on the information-wealthy at great expense to the information-poor. As ICT becomes the primary method for accessing and manipulating information, it ought to be treated as a foundational layer of the information economy. I argue that by maximizing the liberties (freedom to use, freedom to distribute, freedom to modify, and so on) associated with certain computer software, an incentives-rich and stable environment can be established in ICT that will foster development of the information economy among the information poor. I suggest that the now-mature Free and Open Source Software paradigm, which has already produced widely-used enterprise-class applications, can be harnessed in support of these ends.  相似文献

U.S. advocacy for increased international intellectual property protection and a free and open Internet has been criticized as being inconsistent at best and hypocritical at worst. Placing U.S. copyright and Internet policy in a historical context and using Susan Strange's concepts of structural power and knowledge structures, we argue that copyright and Internet policies cannot be analyzed in isolation, but are intimately and inextricably linked forms of knowledge regulation. All knowledge regulation policies involve balancing access and restriction. Our analysis suggests that the current U.S. policy of Internet freedom and strong copyright protection represents a particular, historically situated strategy designed to exert structural power in the global information economy: Free flow of information creates markets by exposure to intellectual properties, while copyright secures economic benefit to copyright holders from the flow. We argue that a full and honest debate over issues of information access requires acknowledgment of contemporary and conflicting values, with the realization that different societies and interests will weigh access and dissemination differently. Recognizing as legitimate and incorporating these different perspectives into the global governance structures of the Internet comprise the key challenge facing those who favor truly democratic global Internet governance.  相似文献

The Rhetorical Dynamics of Gender Harassment On-Line   总被引:3,自引:0,他引:3  
This article compares two extended interactions that took place recently on the Internet, one from a recreational Internet Relay Chat (IRC)channel, and the other from an academic listserv discussion group. The two interactions exhibit similar gender dynamics, which can be characterized as harassment of female by male participants. This harassment takes different forms, in keeping with the possibilities inherent in the two modes of computer-mediated communication. Whereas female participants on IRC are kicked off the channel, in the discussion group harassers must rely exclusively on language to intimidate and silence. This "rhetoric of harassment" crucially invokes libertarian principles of freedom of expression, constructing women's resistance as "censorship." A rhetorical analysis of the two harassment episodes thus sheds light on the means used to construct and maintain asymmetrical gender and power dynamics in different modes of CMC.  相似文献

互联网正在受到越来越强大的规制。权力与资本的联合,正在改变当前互联网的架构。对互联网进行一定程度与性质的规制是应该的,但是超越了自由和危害到人本身的基本权利则是有危害的。危险的不仅是互联网本身,危险更存在于人们对此影响是否会侵蚀自由、民主毫无认识,或者自动地把对于自由的认识交付他人,把自由拱手让给他人。在此,偏颇的科学教育充当了帮凶。本文运用科学实践哲学通过两个案例对于这种危害和科学教育的偏颇做了论证。  相似文献

With the continuous development of space and sensor technologies during the last 40 years, ocean remote sensing has entered into the big-data era with typical five-V (volume, variety, value, velocity and veracity) characteristics. Ocean remote-sensing data archives reach several tens of petabytes and massive satellite data are acquired worldwide daily. To precisely, efficiently and intelligently mine the useful information submerged in such ocean remote-sensing data sets is a big challenge. Deep learning—a powerful technology recently emerging in the machine-learning field—has demonstrated its more significant superiority over traditional physical- or statistical-based algorithms for image-information extraction in many industrial-field applications and starts to draw interest in ocean remote-sensing applications. In this review paper, we first systematically reviewed two deep-learning frameworks that carry out ocean remote-sensing-image classifications and then presented eight typical applications in ocean internal-wave/eddy/oil-spill/coastal-inundation/sea-ice/green-algae/ship/coral-reef mapping from different types of ocean remote-sensing imagery to show how effective these deep-learning frameworks are. Researchers can also readily modify these existing frameworks for information mining of other kinds of remote-sensing imagery.  相似文献

Cultured Technology: The Internet and Religious Fundamentalism   总被引:1,自引:0,他引:1  
In this article we identify four principal dimensions of religious fundamentalism as they interact with the Internet: hierarchy, patriarchy, discipline, and seclusion. We also develop the concept of cultured technology, and analyze the ways communities reshape a technology and make it a part of their culture, while at the same time changing their customary ways of life and unwritten laws to adapt to it. Later, we give examples for our theoretical framework through an empirical examination of ultra-Orthodox Jewish communities in Israel. Our empirical study is based on a data set of 686,192 users and 60,346 virtual communities. The results show the complexity of interactions between religious fundamentalism and the Internet, and invite further discussions of cultured technology as a means to understand how the Internet has been culturally constructed, modified, and adapted to the needs of fundamentalist communities and how they in turn have been affected by it.  相似文献
