Supporting interactive, multiplayer games on mobile phones over cellular networks is a difficult problem. It is particularly relevant now with the explosion of mostly single-player or turn-based games on mobile phones.

BACKGROUND, AIMS AND DESIGN The increase in mobile telephone-only households may be a source of bias for traditional landline gambling prevalence surveys. Aims were to: (1) identify Australian gambling participation and problem gambling prevalence using a dual-frame (50% landline and 50% mobile telephone) computer-assisted telephone interviewing methodology; (2) explore the predictors of sample...

For almost three decades telephone household surveys have increased in number and size. There has been a corresponding development of telephone sampling techniques that attempted to improve the cost effectiveness of telephone surveys. For example, the twostage RDD sampling devis ed by Mitofsky (1970) and revised by Waksberg (1978) provided nearly complete coverage of both listed and unlisted te...
