1.1 Introduction

Ratios crop up often in official statistics. The government wants the teacher–pupil ratio in schools to be increased to one teacher to thirty pupils or less. The birth rate has fallen: the ratio of children to women of child bearing age has gone down. It used to be 2.4 to 1, and now it is 1.9 to 1. Predictions for the ratio of working adults to retired adults is disturbing. Predictions are, that by 2030 the ratio will be two working adults to every retired person, instead of three to one no

4.1 First aid

It is not required that students be trained in first aid. It is, however, important that a first aid kit is carried when you are likely to be away from immediate assistance. First aid must be rendered at once, and medical and relief help should be sought if necessary. It is important that appropriate first aid skills for use in the field are understood by those who might need them and that the procedures for enlisting help are known.

  • ‘Regions’ and ‘regionalism’ in Western Europe display great diversity in economic, social, cultural and political terms, varying not only between states but also within particular states (as exemplified by the UK and Spain).

  • Regions vary widely in their size, population, levels of economic development, historical origins, contemporary identity, cultural distinctiveness and political activism (or in some cases the lack of distinctive

5 Summary and conclusion

In this unit we have considered questions surrounding the future of school geography. This may at first seem an odd question, but it is salutary to remember that the advocates of geography had to work very hard to make the case for the subject's place in the English National Curriculum.

As the unit sought to show, even if we can agree that geography has an important role to play in schools, opinions vary as to the purpose of the subject:

  • Is it a

Learning outcomes

After studying this unit you should be able to:

  • develop your understanding of the process of teaching and learning in classrooms, and the role of language in that process;

  • appreciate how a sociocultural approach can be used to make critical, constructive analyses of classroom interaction in a variety of second language learning contexts;

  • use this knowledge to reflect on second language learning processes in the classrooms you know.

3.1 Introduction

So what are the principal energy systems used by humanity at present, and how sustainable are they?

Until quite recently, human energy requirements were modest and our supplies came either from harnessing natural processes such as the growth of plants, which provided wood for heating and food to energise human or animal muscles, or from the power of water and wind, used to drive simple machinery.

3.2 The disaster

The 39-year-old Silver Bridge collapsed suddenly at about 5 p.m. on 15 December 1967 when the roadway was filled with rush-hour traffic – 37 vehicles were trapped on the roadway.

The first signs of collapse were later recounted by the survivors. Many occupants of the cars on the bridge had felt it ‘quivering’ before it fell. Most witnesses had then heard ‘cracking’ or ‘popping’ noises, some saying that it sounded like a ‘shotgun blast’. After this, the bridge started d

2.7 (iii) Royal Commissions

Royal Commissions occasionally report to Parliament with recommendations for legislation which may be taken up as part of the Government's legislative programme. Royal Commissions are advisory committees established by the Government – though formally appointed by the Crown, hence the ‘Royal’ – to investigate any subject the Government sees fit to refer to one. They are often used for non-party political issues, or for issues that a Government wishes to be seen as addressing in a non-

6.2.1 The need for a reference frame for describing the Universe

The speed of the Earth in its orbit round the Sun is 29.8 km s−1, in a heliocentric frame. But to specify the velocity vector, it is not sufficient to specify the Sun as the origin of the coordinate system; fixed directions must also be identified.

5.5 Problems with transactions

A distributed transaction is a sequence of operations applied to a number of distributed databases which form a single functional step. For example, a transaction which moves an amount of money from a customer's account to an account owned by the same customer is an example of a transaction. It consists of two operations: the operation of debiting one account and the operation of crediting another account. There are a number of problems associated with distributed transactions.

1.6.1 Realising the design

So far we have been concerned only with the specification of a logical schema. We now need our database to be created according to the definitions we have produced. For an implementation with a relational DBMS, this will involve the use of SQL to create tables and constraints that satisfy the logical schema description and the choice of appropriate storage schema (if the DBMS permits that level of control).

One way to achieve this is to write the appropriate SQL DDL statements into a f

4.1 Introduction

The main resource for this section is the play Last Call by Mike Walker, the play that follows Call Waiting in the BBC Radio 4 series. This is a text rich in ethical issues, and, as you will see, these include not only ‘big’ questions (concerning, for example, the deployment and use of surveillance technologies) but, interestingly, everyday issues that you or I might face in our professional practice. This is, indeed, one of the reasons why I have chosen to explore this play

6.1 ‘Maybe you can look, but you cannot touch’: asylum and restricting access to welfa

So far we have considered meanings of citizenship in terms of legal status, national identity and belonging. In this section we want to explore it in terms of ‘access to welfare’, recognising that people who flee from their country of origin are likely to require assistance and support when they arrive. There is a long history of the state linking controls on access to welfare and control of migration since the 1905 Aliens Act (Lewis, 2003).
