Social networks have formed the basis of many studies into large networks analysis. Whilst much is already known regarding efficient algorithms for large networks analysis, data mining, knowledge diffusion, anomaly detection, viral marketing, to mention. More recent research is focussing on new classes of efficient approximate algorithms that can scale to billion nodes and edges. To this end, t...

It is unclear whether introducing organised mammography screening programmes in a population where opportunistic screening is prevalent results in the two types of screening mainly competing against each other or attracting different groups of women. To compare women who participate in organised screening and those who prefer opportunistic screening, we conducted a prospective study of 932 wome...

This article summarises briefly what is known internationally about how ‘organised crimes’ are financed and how this differs from the financing of licit businesses. It shows how illicit financing might and does operate, noting that a key issue is the social capital of offenders and their access to illicit finance which ironically, may be easier if controls make it harder to launder money. It th...

Peer-to-Peer (P2P) systems provide a new solution to distributed information and resource sharing because of its outstanding properties in decentralisation, dynamics, flexibility, autonomy and cooperation, summarised as DDFAC in this paper. After a detailed analysis of the current P2P literature, this paper suggests to better exploit peer social relationships and peer autonomy in order to achie...

purpose of this paper is to present an implementation of a method that combines active and passive methods to measure and estimate the main performance parameters in IP networks. More specifically the method integrates performance and flow measurements. The main features of the method and an implementation using the flow meter NeTraMet are described. Test results for packet delays and delay var...

At the beginning of the 21 st Century, before the power of online social networking became apparent, several studies speculated about the likely structure of organised cybercrime (Mann and Sutton 1998; Brenner 2002). In the light of new data on cybercriminal organisations, this paper sets out to revisit their claims. In collaboration with the Serious Organised Crime Agency (SOCA), this paper ex...

Typologies are intended to assist researchers in understanding complex social phenomena. This paper reviews the current literature on organised crime typologies and argues that the majority of organised crime typologies are reflected to some extent in a typology developed by the United Nations Office on Drugs and Crime (UNODC) in 2002. Organised crime typologies can be categorised into three gr...
