2.1 Introduction

The late Dr. Colin Patterson was a palaeontologist at the Natural History Museum, and an authority on systematic methods. He played a prominent role in promoting cladistics, the method now most widely employed for phylogenetic analysis. He introduces the sequence of audio clips by drawing attention to the connection perceived by Darwin beteen the systematic grouping of species into higher taxa and the closeness of their evolutionary relationships (‘propinquity of descent’).

3.4 How does the EU operate?

The EU operates through institutions created in the treaties. These institutions can have decision-making powers, law-making powers or may act as part of a checking and consultation procedure.

The institutions include:

  1. The European Parliament (represents the people of the EU).

  2. The Council of the European Union (represents the member states of the EU).

  3. The European Commission (represents the interests of the EU).

Social issues and GM crops
The genetic manipulation of plants and animals and their use in agriculture is one of the most controversial scientific developments of recent times. This unt takes a look at the 'science behind the headlines' and the complex interactions between scientific and social factors. By the end of the unit it's hoped that you will have a clearer idea of both what is GM makes possible as well as what may be thought desirable.Author(s): Creator not set

2.9 Roots of polynomials

We begin by reminding you of what we mean by the word ‘root’. In this unit we use this term in two different, but related, senses, as given below.

If p(z) is a polynomial, then the solutions of the polynomial equation p(z) = 0 are called the roots o

2.3.8 Sphere

Surfaces can be constructed in a similar way from plane figures other than polygons. For example, starting with a disc, we can fold the left-hand half over onto the right-hand half, and identify the edges labelled a, as shown in Figure 36; this is rather like zipping up a purse, or ‘crimping’ a Cornish pasti

5.12 Pole and Stewart report

Apparently prepared using the same methodology as Law, Pole and Stewart produced a report that calculated the loads at various points in the bridge under live locomotive loads and wind loading at various pressures. Stewart was employed by Bouch to perform the original design calculations for the bridge, while Pole was brought in as an independent expert. He had extensive experience of use of different materials in bridges, and indeed, had written a standard text book for engineers on the subj

Wordsworth re-visited
Renowned as one the key figures of Romanticism, William Wordsworth broke through poetic traditions and barriers to produce verse that redefined the principles underlying the writing of poetry, placing the poet's emotions and interaction with a natural, pastoral world at the centre of poetic philosophy. Wordsworth's influences are a topic of immense academic debate, and this album provides a concise and distinct introduction to the many literary, political and cultural shifts that informed and in

2.4 Effects on marine systems

In the marine environment, nutrient enrichment is suspected when surface phytoplankton blooms are seen to occur more frequently and for longer periods. Some species of phytoplankton release toxic compounds and can cause mass mortality of other marine life in the vicinity of the bloom. Changes in the relative abundance of phytoplankton species may also occur, with knock-on effects throughout the food web, as many zooplankton grazers have distinct feeding preferences. In sheltered estuarine are

4.12.2 Expertise

Delegated legislation by its very nature concerns specialist technical and/or local knowledge. So it is an advantage for such specialist provisions to be dealt with by those who have this knowledge rather than by Members of Parliament who generally would not have the required specialist or local knowledge.

5.4.1 Leadership roles

  • The classic ‘scientific’ view of the leader is as the central ‘controller’ – planning, monitoring and regulating.

  • The more ‘democratic’ view sees the role as facilitator, or coordinator.

  • The more ‘educational’ view sees it as that of adviser, teacher, source of expertise, etc.

7 Conclusion

Delacroix’s fascination with the Oriental and the exotic both fuelled and influenced his Romantic tendencies. His journey to Morocco encouraged him to balance Romantic obsessiveness with classical restraint and to inject a significant degree of enlightened empirical observation into his art. He was seduced by the colour and the light of this foreign land, but his sensuous enjoyment of the picturesque developed alongside a scientific interest in colour and form. His responses to Morocco rema

4.1 What it means to be good at managing

What does it mean to be ‘good at managing’ and what part does systems thinking and practice play? One way to explore the first question is to ask what you know about your work that a school leaver, or someone fresh from university, would not know. Consider a senior secretary, for example, someone who clearly has a fair amount of managing to do, in our terms. Such a person must have certain basic skills and knowledge (in word-processing, filing, etc.) the foundation of which will have been

3.4.2 Distinguishing

In comparison with the mechanism of overruling, which is rarely used, the main device for avoiding binding precedent is that of distinguishing. As has been previously stated, the ratio decidendi of any case is based upon the material facts of the case. This opens up the possibility that a court may regard the facts of the case before it as significantly different from the facts of a cited precedent, so it will not find itself bound to follow that precedent. Judges use the device of dis
