We present theory and evidence to suggest that, in the context of analysing global poverty, the EKS approach to estimating purchasing power parities yields more appropriate international comparison of real incomes than the Geary-Khamis approach. Our analysis of the 1996 International Comparison Project data confirms that the Geary-Khamis approach leads to(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)
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)
Abstract: The political blogosphere has recently been the focus of attention for social network analysis and applications of network and graph theory. In a recent paper, Adamic and Glance (2005) report differences between the linking behavior of politically conservative vs. politically liberal Web bloggers. We construct a simple agent-based network(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)
In this paper we describe the development of e-Research tools enabling remote access and analysis of large-scale web crawl data. The tools are being developed in the context of a planned research project titled the “.au Census”, the aim of which is to gain new insights into Australian commerce and society using data from large-scale crawls of the Australian(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.
