1.1 The transition from planning to action

In working on a project, it is sometimes difficult to make the transition from planning to action. It usually falls to the manager, as leader of the project, to make sure that activities are started; but not before it is clear who should carry out which tasks, and when. The first step for the project manager is to ensure that the plan is communicated to those who will be working on the project. It is not always safe to assume that others will understand the plan or its implications, particula

8.5 MMR safety

Fitzpatrick, M. (2004) Chapter 8 ‘The Lancet Paper’ taken from MMR and Autism: What Parents Need to Know, London, Routledge. Copyright © 2004 Michael Fitzpatrick.

In January 2001 Dr Wakefield adopted a radically different tack in the campaign against MMR. He now turned to the field of public health and vaccination policy, questioning whether appropriate safety procedures had been followed when MMR was introduced into Britain in the late 1980s. In a paper writte

Providing for Gifted and Talented Youth
The announcement of a national register of gifted and talented pupils has raised questions over how we provide for the most able children. Commentators have raised concerns over elitism, how we select people for the register and even whether this is the most effective approach to dealing with gifted provision in schools. Professor Deborah Eyre is the Director of the National Academy for Gifted and Talented Youth, based at the University of Warwick. NAGTY is tasked with identifying the top 5%

2.7 Geological problems in coal mines

A modern coalface is a very complex operation that represents a large investment in terms of capital, labour and planning. Cutting machines and lengthy conveyors are inflexible and require uniform geological conditions to maximize output. What then are the effects of geological variations on such a mining system?

Geological factors control the selection of working areas. The two principal geological conditions that affect mining operations are, first, the nature of the coal-bearing rock

4.1 Design guidelines and their limitations

Having considered practical accessibility measures we can implement in creating eLearning materials, we now take a closer look at the guidelines that are available to support the development of accessible resources. Guidelines are available from many different sources and cover a variety of learning environments, however they are unlikely to resolve all accessibility issues in any given eLearning context, and should not be treated as a complete solution.

7 Managing the BSE/vCJD episode: an overview

Having concentrated so far on the 'science' behind BSE and vCJD, we now turn our attention to how the episode was managed by scientists, politicians and other relevant decision makers. Not surprisingly, we shall find that the themes of communication, risk and ethical issues are inextricably linked to that of decision making (at local, national and international levels).

Over the years, the UK Government implemented a great many Orders and Regulations, amending several of these more than

This secondary electron SEM image shows the cementite delineating prior austenite grain boundaries with a thin layer. The amount of proeutectoid phase is very low, with the majority of the area being taken by the pearlite eutectoid. Again each pearlite cell has a different orientation with the ferrite phase being selectively etched.

1.3 Designing alternative programmes and curricula

Assuming that both the content of mathematics and the processes need to be included in programmes and curricula, the problem becomes one of how a suitable curriculum can be structured. One possibility is to construct a very specific curriculum with clearly defined objectives for both content and processes separately, and possibly with suggested learning activities. However, content and process are two complementary ways of viewing the subject.

An alternative is to see the curriculum in

2.5 Obesity and ageing

So, it seems that a part of the explanation for Ron's obesity, and the health problems that have led him to seek medical advice, may relate to the environment in which he is living, and more specifically the diet that he has chosen. It may also be a diet that is especially effective in activating the reward circuits in Ron's brain. However, Ron is also in his later middle age. A longitudinal study of people of this age in the USA suggests that average body weight increases by 1–2 kg per dec

4.2 Experimental domestication of foxes

In 1959, the Russian geneticist Dmitri K. Belyaev (1917–1985) launched a long-term experiment to tame captive-bred red foxes by selecting for a single behavioural trait: lack of fear and aggression towards humans. Over 40 years, more than 45 000 foxes were bred in captivity at a remote farm near Novosibirsk, Siberia. Various behavioural, physiological and morphological characters were studied in each fox. Selection for tameness was strict: each animal was assessed once a month for seven mon

5 Conclusion

Domesticated organisms evolve in artificial environments under artificial selection, and opportunistic or enforced hybridisation often occurs between species that would not normally interbreed. Natural selection cannot be eliminated and continues to operate. At least two different forms of dwarfism are common in domesticated livestock and humans, but only the rarer midget type of dwarfism occurs in wild lineages. Domesticated mammals and birds have distinctive patterns of skin pigmentation th
