Domestic helpers' privacy

AnalysisVideo surveillance of domestic helpers by their employers in order to confirm parental fears of child abuse has recently become topical in Hong Kong, as a result of number of recent instances coming before the courts and reported in the press. The lawfulness of such surveillance is questioned by the author, who argues that the correct interpretation of the 'domestic purposes' exemption in section 52 of the Personal Data (Privacy) Ordinance does not apply to this kind of activity. However, given the very real interests of parents in protecting their children from violence at the hands of domestic helpers, the author argues for the adoption by the Commissioner of Privacy of a code of practice on the subject under section 12 of the Ordinance.published_or_final_versio

Coherent laminar and turbulent motion of toroidal vortex bundles

Motivated by experiments performed in superfluid helium, we study numerically the motion of toroidal bundles of vortex filaments in an inviscid fluid. We find that the evolution of these large-scale vortex structures involves the generalised leapfrogging of the constituent vortex rings. Despite three dimensional perturbations in the form of Kelvin waves and vortex reconnections, toroidal vortex bundles retain their coherence over a relatively large distance (compared to their size), in agreement with experimental observations.Comment: 22 pages, 12 figure
