6 Population growth

Earlier it was stated that three factors check population growth. These are predation, disease and insufficient food supply. For much of our history, our ancestors’ numbers were indeed limited by wars, disease and famine. The world population remained relatively stable until around 300 years ago. Then at the beginning of the 19th century (100 years after population growth started its geometric increase), the demographer Thomas Malthus predicted that population growth would outstrip food pro

7.1 The advantages of reuseability

Reuse is the process of building new software from existing software assets, rather than starting from scratch. Reuse is an important factor in building flexible products that can be changed quickly in response to changes in requirements.

One of the advantages claimed of object technology is that it encourages a disciplined approach that facilitates reuse. Encapsulation encourages better designs that can be reused in a more reliable way, as there is exact knowledge of which oper

1.1 Why Glasgow?

Glasgow fulfilled our aims and was also an interesting case study having, arguably, been the most successful among British cities in developing/manufacturing a new identity in the ‘post-industrial’ era. Glasgow illustrates:

2.5 Critical current

The current density for a steady current flowing along a wire in its normal state is essentially uniform over its cross-section. A consequence of this is that the magnetic field strength B within a wire of radius a, carrying current I, increases linearly with distance from the centre of the wire, and reaches a maximum value of μ0I / 2Author(s): The Open University

7.2 Frameworks

A framework is a set of classes with well-defined interactions which are designed to solve specific problems. Frameworks are usually developed for a specific domain of application, say financial management or document preparation. They go some way towards a complete solution, but require some degree of customisation, usually through the creation of subclasses within the framework or by overriding operations. Coplien suggests:

3.1 Clubs and societies

The milieu was urban. It was not a business of isolated individuals working in country estates, or of secluded academics, cloistered within unworldly universities. The scene was convivial, social. The focus was Edinburgh, although Glasgow and Aberdeen were active too. Cities were small. Even the capital was intimate enough for its intelligentsia to be able to meet regularly and casually. ‘Here I stand, at what is called the Cross of Edinburgh’, wrote an excited visitor, ‘and within a fe

7.1 Introduction

So far we have presented two pieces of evidence pointing to the occurrence of a big bang: the redshift of the galaxies (indicating the continuing expansion of the Universe), and the 3 K radiation (the remnant of the primordial radiation). But there is a third imprint such a big bang ought to have left on our present-day world. We cannot at this juncture trace out the full sequence of events following the instant of the big bang (that can only be done after we have worked through the next two

5.6 Stages of an Executive Bill

To provide a flavour of the consideration of Bills, we will now look at the stages of an Executive Bill.

One of the unique features of the Scottish Parliament is its openness. There are processes for wide consultation, an open evidence process at committees, the ability of the public and interested parties to liaise directly with MSPs, and the ability to lobby for amendments to a Bill. For all these things the Scottish Parliament has received international recognition.
