5.3.4 Plan testing and validation

It is one thing to have a plan; it is another thing to have a plan that you can rely on to work. There is an old military maxim that ‘A plan only gets you into first contact with the enemy. After that, you fly by the seat of your pants’ (Anon). A 1993 IBM report on business continuity planning confirmed this when it revealed that ‘half of the plans failed completely or substantially when they were first tested’ (IBM, 1993, p. 5).

The IBM report identified three categories of pla

3.7.4 The carbon-nanotube tip

A way of escaping the issues affecting process compatibility that arise from the use of techniques such as oxidation sharpening is simply to assemble the probe from separate parts – and this has been successfully done using carbon nanotubes. Single-walled carbon nanotubes can have diameters as small as 0.4 nm, but more typically they are of the order of 1 to 2 nm. This represents a great improvement on the radii of curvature achieved with oxidation sharpening. One might have thought that it

1.2.8 In praise of cheap offshore labour? continued

There are two points which are central to this line of thinking. One, according to Wolf (2004), is that the whole process, as odd as it may sound, is about mutual exploitation. Outside firms do indeed exploit the poor by taking advantage of the profitable opportunities that a pool of cheap labour represents. But Indonesian or Chinese workers, for instance, could be said to exploit the incoming firms by extracting higher pay from them and taking advantage of opportunities that previousl

Egyptian economy and non-royal women: their status in public life
The online version of a lecture given 21 June, 1995, at Brown University, by William A. Ward deals with the status of women in ancient Egypt society. Although pharaonic Egypt was in most respects a male society, with men holding positions in public life while women dominated the private life, Ward points to the fact that there is plenty of evidence that women, throughout ancient Egyptian civilisation could own, bequeath and inherit land. Furthermore women seem to have been able to hold positions
