This paper offers a rearticulation and defence of the modal account of luck that I developed in earlier work (e.g., Pritchard 2005). In particular, the proposal is situated within a certain methodology, a component of which is paying due attention to the cognitive science literature on luck (and risk) ascriptions. It is shown that with the modal account of luck properly articulated it can adequ...

Recent years have seen an explosion in online collaborative tagging, the most prevalent visualization of which are tag clouds. Despite their popularity, tag clouds suffer from limitations of separation from tagged items, lack of relational information between tags and a less-than-fully interactive experience. In this paper we introduce Tagscape, a tag system interface that attempts to address t...

Standard tours combined with lack of information make many tourists miss some important experiences a destination has to offer. The target of the Dynamic Tour Guide (DTG) is to discover Tour Building Blocks (TBB), e.g. attractions like sights or restaurants, dependent on the actual context which is defined by personal interests, location and schedule of a tourist. It determines current informat...

the purpose of this research was market segmentation of sport tourism in iran for foreign tourists and modeling a target market. a questionnaire including 53 items was developed by researchers. the validity and reliability of the questionnaire were examined and approved (?=0.93). it was distributed among 710 international participants from 35 countries attending fajr international sports event ...

In this work, we focus on the novel application of learning the diffusion dynamics of visitors among attractions at a large theme park using only aggregate information about waiting times at attractions. Main contributions include formulating optimisation models to compute diffusion dynamics. We also developed algorithm capable of dealing with noise in the data to populate parameters in the opt...

The Poisson-Boltzmann theory for colloidal electrostatic interactions predicts that charged colloidal spheres dispersed in water should repel each other, even when confined by charged surfaces. Direct measurements on highly charged polystyrene spheres, however, reveal strong, long-ranged confinement-induced attractions that have yet to be explained. We demonstrate that anomalous attractions als...
