3.2 Recording on the wire

A paper published by Oberlin Smith in an 1888 issue of Electrical World discussed the possibilities for recording sound using the property of magnetism. He envisaged a cotton thread impregnated with steel dust passing through a coil carrying a current controlled by a microphone. The variations with the sound in the strength of the current would cause corresponding magnetic fluctuations in the magnetic medium. Unfortunately he dismissed his idea because, as he said in his paper, he thou

3.5 Evaluating claims, using evidence

Where does this exploration of evidence lead us? Can we decisively confirm or refute the common-sense stories of the crime problem in the UK?

Through an investigation of quantitative statistical evidence we certainly have some support for the claim that crime has risen considerably. But there are also doubts. The official statistics do not reflect unrecorded crime, and as one probes more deeply into the statistics we find that only certain types of crime have been on the rise. In any ca

5.7.1 Plan preparation

Perhaps the first question to ask is ‘What is an emergency plan?’ Dodswell, in his guide to business continuity management, defined an ‘emergency management plan’ as simply:

A plan which supports the emergency management team by providing them with information and guidelines.

Understanding Globalisation
What do we mean when we say globalisation? Does the growth of globalisation hinder or benefit mankind? It’s a common assumption that countries globalise but in fact it’s not nations themselves but rather the Industries and companies that trade within and outside their borders. As new forms of technology emerge and organisations expand they erode traditional boundaries and in recent times there has been a rise in interconnectedness of markets across the world.

1.12 The politics of representation

We turn now to consider Diana as an icon, as the subject of discourse. It could be said that Diana and the many words written about her form a discursive space (Gilbert et al., 1999; Silverstone, 1998). She is the rather enigmatic centre of many competing representations of royalty, femininity, democracy, the family, morality, celebrity, fashion, private versus public life which jostle with each other. Such a discursive space is a place of argument. To use another metaphor, it i
