Early warning does not happen every day. So when hazards occur, it is important that the experience is analyzed so that future responses can be enhanced. Here is a report on how warnings worked (or did not) on the Pacific Coast of Australia in relation to the tsunami generated by the Chilean earthquake of Saturday. It is a pity that the potential of cell broadcasting that can be targeted to low-lying areas that are in danger, without knowing any of the numbers of the mobile phones belonging to the people physically present and without congestion. The Gold Coast authorities used SMS for 10,000 people.
In the context of the debates about banning mobiles for school children, the issue of phones that constrain use has become relevant. The NYT has done a full survey of the options available to parents in the US, an excerpt of which is given below. Why doesn’t someone do a similar survey for India, Sri Lanka, etc.? Now for some real cellphones.
The obvious has been confirmed by science. It is not possible to text and drive at the same time (or text, drive and not kill other people and/or yourself at the same time) The first study of drivers texting inside their vehicles shows that the risk sharply exceeds previous estimates based on laboratory research — and far surpasses the dangers of other driving distractions. The new study, which entailed outfitting the cabs of long-haul trucks with video cameras over 18 months, found that when the drivers texted, their collision risk was 23 times greater than when not texting.
