The core of the Web is a hyperlink navigation system collaboratively set up by webmasters to help users find desired information. While it is well known that search engines are important for navigation, the extent to which search has led to a mismatch between hyperlinks and the pathways that users actually take has not been quantified. By applying network(More)
A social movement consists of organisations that are linked together by a common purpose or issue (the protection of the natural environment, in the case of the environmental movement). Competition between social movement organisations for members, resources and attention can be conceptualised using multi-organisational fields, and the explicit(More)

Environmental activist groups are active users of the Internet, a relatively low-cost medium with global reach that can facilitate the formation of global virtual commu nities (thus compensating for a lack of critical mass of activists in a given country). Web data are therefore very useful for social science research into the mobilisation and coordination(More)
Albania provides a small amount of social assistance to nearly 20 percent of its population through a system that allows some community discretion in determining distribution. This study investigates how well this social assistance program is targeted to the poor. Relative to other safety net programs in low-income countries, social assistance in Albania is(More)
In this paper we propose relational hyperlink analysis (RHA) as a distinct approach for empirical social science research into hyperlink networks on the World Wide Web. We demonstrate this approach, which employs the ideas and techniques of social network analysis (in particular, exponential random graph modeling), in a study of the hyperlinking behaviors(More)
This paper investigates political parties' use of a new form of political communication – online horizontal communication through hyperlinks. Specifically, we argue that hyperlinks facilitate a set of new and important communicative functions and have significant implications for parties' online visibility and prominence for voters. These propositions are(More)
This paper presents a preliminary analysis of Websites contained in a large-scale crawl of the .au domain that was collected by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in late 2005. Our analysis is based on a 10 percent random sample of the CSIRO crawl dataset, which contains around 10 million Web pages from approximately(More)
Nanotechnology-or the science of technology development at the atomic level-is increasingly being used in a range of industries including textiles and agriculture. While nano-proponents emphasize benefits such as increased food yields and novel consumer goods, nanotechnology has also generated concerns about implications for population health and safety. In(More)

The Virtual Observatory for the Study of Online Networks (VOSON) is providing a web-based environment facilitating research into networks. While the initial focus of the VOSON Project is on empirical analysis of online networks by social scientists, we aim to eventually facilitate network research in other disciplines such as biology and applied physics.(More)
