5.1 Genetic databases and disease Section 2 looked at data and information from two different perspectives: that of the individual and that of commercial organisation.

2.8 Attenuation and distortion As a signal travels from one device to another it has two problems to overcome. The first is that it gets weaker the further it travels, because some of its energy is absorbed by the transmission medium. This effect is known as attenuation. The extent of attenuation depends on the distance it has to travel and on the type of medium it is travelling through. An amplifier can be used to boost the signal power at the transmitter and receiver, and if necessary at various points in the tran

Two theories dominated: social Darwinism and eugenics. Social Darwinism drew on Darwin's ideas of natural selection and emphasised the contribution of the fittest and most superior individuals to the survival of the human species. The social Darwinists, who included some of the most prominent thinkers of their time, believed that social 10.5 Desire to help others This is a less common motivation but it shows not everyone is driven by money. In 1991 the inventor Trevor Baylis saw a BBC documentary about the spread of HIV/AIDS in Africa. What was needed was a way of broadcasting the safe-sex message to people in areas without electricity and where batteries for a radio could cost a month's wages.
