They have been approved for circulation by RAND Europe but have not been formally edited or peer reviewed. Unless otherwise indicated, working papers can be quoted and cited without(More)
This paper discusses the status of research on detection of fraud undertaken as part of the European Commission-funded ACTS ASPeCT (Advanced Security for Personal Communications Technologies) project. A first task has been the identification of possible fraud scenarios and of typical fraud indicators which can be mapped to data in toll tickets. Currently,(More)
Agility skill is important in Australian Rules football (ARF) as it enables an attacking player to successfully evade an opponent. To date, no research has examined offensive agility techniques in ARF. There were two purposes of this study: first, to compare the change of direction (COD) speed of three offensive agility techniques, and second, compare the(More)
This paper discusses the current status of research on fraud detection undertaken as part of the European Commission-funded ACTS ASPeCT (Advanced Security for Personal Communications Technologies) project, by Royal Holloway University of London. Using a recurrent neural network technique, we uniformly distribute prototypes over toll tickets, sampled from(More)
Public acceptability influences policy action, but the most acceptable policies are not always the most effective. This discrete choice experiment provides a novel investigation of the acceptability of different interventions to reduce alcohol consumption and the effect of information on expected effectiveness, using a UK general population sample of 1202(More)
Fraud is costing the mobile communications industry millions of pounds a year. A rapid solution is needed to reduce fraudulent activity in analogue networks and preventative measures are required to protect GSM and later UMTS. A joint European project`Advanced Security for Personal Communications Tech-nologies' (ASPeCT), part of the ACTS programme 1 , has(More)
During the course of the European project Advanced Security for Personal Communication Technologies" ASPeCT, we h a ve developed some rule-based and neural network architectures as a number of diierent fraud detection tools for GSM networks. We h a ve n o w i n tegrated these diierent techniques int o a h ybrid detection tool. We optimized the performance(More)
This paper presents empirical findings from the comparison between two principal preference elicitation techniques: discrete choice experiments and profile-based best-worst scaling. Best-worst scaling involves less cognitive burden for respondents and provides more information than traditional "pick-one" tasks asked in discrete choice experiments. However,(More)
