4.3 Character code functions

Many programming languages provide two functions associated with the character codes (see Table 2). We shall call these functions ASC and CHR. ASC takes a character as input, and returns the integer giving the ASCII code of the input character. CHR returns the character whose ASCII code is the input inte

7.2 Adding 2's complement integers

The leftmost bit at the start of a 2's complement integer (which represents the presence or absence of the weighting −128) is treated in just the same way as all the other bits in the integers. So the rules given at the start of Section 7.1 for adding unsigned integers can be used.

4.4.1 Engaging with the content

For example, when I read in paragraph 3 of Layard's article that ‘41 per cent of people in the top quarter of incomes are ‘very happy’’ I asked myself:

  • Why is ‘very happy’ in quotation marks?

  • Is 41 per cent about what I'd expect?

  • What is this telling me?

As soon as I thought about it, I realised that ‘very happy’ could be a response that people had ticked on a questionnaire. Perhaps th

2.2 The ‘academic’ style

You might also be put off by the ‘academic’ style of writing. In everyday life, what you read is usually written to grab your attention and get a message across quickly before you ‘switch channels’. By contrast, academic texts often raise broad, abstract questions and are unconcerned about arriving at quick answers. For example, where a newspaper headline might say:

2.1.3 Concept cards

Another way to tackle unfamiliar words is to start a ‘concept card’ system, using index cards. When you meet a word which seems important, take a new card and write the word at the top, followed by any useful information you have found. File the cards alphabetically and add details as you come across new information. (It is worth getting an index card box anyway, then you can try out various ways of using it to organise your studies.)

2.1 The significance of geography as a subject

It has been argued that geography ‘has been hijacked by environmentalists’. Following the publication of his original article, ‘Constructing a value map’ (see under the link below), Alex Standish (a former geography teacher) appeared on the Radio 4 Today programme to discuss this topic. Listen to the interview again and read the transcript again by clicking on the link below.

6.5 Training at high altitude

Many of the world's best endurance athletes train at high altitudes – a long way above sea level – to improve their performance. At high altitudes there is less oxygen in the air and it's believed that the body has to work harder to extract what little oxygen remains. When the athlete returns to lower altitudes, their body retains the ability to use oxygen more efficiently and their performance will have improved.
