Concerns over equity of access to higher education are widespread, but there is significant disagreement over what should constitute a fair system. This article assesses diverse conceptualisations of equity and explores the ways in which they embody themselves in the policies of three systems, those of England, Brazil and Kenya. While showing significant disparities of income level and enrolment ratio, all three have made concerted efforts to expand higher education access, accompanied by increasing stratification in terms of the quality and prestige of institutions. Analysis of policy options and outcomes leads to a proposal of three principles for understanding equity of access: availability, accessibility and horizontality. The third of these principles addresses the little-acknowledged safeguard that disadvantaged students should not be confined to lower-quality institutions, while at the same time allowing for diversity of ethos and disciplinary focus. 相似文献

Since Teece's seminal paper explaining who were the gainers from technological innovation, increased globalization and the information and communication technology revolution have brought new ways for firms to organize and appropriate from innovation. A new more open model of innovation suggests that firms can benefit from sources of innovation that stem from outside the firm. The central theme of this paper is how firms try to unlock communities as complementary assets. These communities exist outside firm boundaries beyond ownership or hierarchical control. Because of practices developed by communities to protect their work, firms need to assign individuals to work in these communities in order to gain access to developments and, to an extent, influence the direction of the community. Using network analysis we show that some software firms sponsor individuals to act strategically within a free and open source software (FOSS) community. Firm sponsored individuals interact with more individuals than interact with them, and also they seek to interact with central individuals in the community. However, we can see differences in how individuals interact, depending on whether their affiliation is with a dedicated FOSS firm or an incumbent in the software industry. Apparently, some firm managers believe they need ‘a man on the inside’ to be able to gain access to communities. 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

Gaps and Bits: Conceptualizing Measurements for Digital Divide/s 总被引:1,自引:0,他引:1
Karine Barzilai-Nahon 《The Information Society》2006,22(5):269-278
Three arguments are raised in this article with regard to the indices used to measure the digital divide. First, I criticize policymakers who rely on simplistic measures of the digital divide, at the expense of a thoughtful analysis of (1) the purpose of the tool, (2) the level of observation, and (3) the method of approaching the data. Second, I argue that networks and associated technologies are not neutral artifacts but are political and social spaces in their structure as well as in their content levels. Accordingly, we need to factor in the context as an important actor in conceptualizing and measuring the digital divide. Third, two general types of indices are used for the measurement of the digital divide(s): focused monotopical indices and comprehensive indices. Monotopical indices are more widely available, while comprehensive ones are rare. I argue that policymakers need to promote comprehensive indices over monotopical indices. Finally, I present a conceptual definition of the digital divide and a framework for developing a comprehensive index to measure it. 相似文献
