3 Pie charts and bar charts

The data set in Table 7 (section 1.8) comprised non-numerical or categorical data. Such data often appear in newspaper reports and are usually represented as one or other of two types of graphical display, one type is called a pie chart and the other a bar chart; these are arguably the graphical displays most familiar to the general public, and are certainly ones that you will have seen before. Pie charts are discussed in section 2.2 and bar charts in section 2.4. Some problems

2.5 Cirrhosis and alcoholism

The data in Table 5, which are given for several countries in Europe and elsewhere, are the average annual alcohol consumption in litres per person and the death rate per 100 000 of the population from cirrhosis and alcoholism. It would seem obvious that the two are related to each o

5.12 Sludge treatment and disposal

The sludge collected in any sedimentation tank in the water treatment process has to be disposed of. In some instances the wet sludge is transported to the nearest sewage works where it is discharged into the raw sewage inlet channel. The presence of the added chemicals can help in the primary sedimentation of the crude sewage. Alternatively, the sludge can be sent to a landfill site after it has been concentrated into a cake by dewatering.

The dewatering is carried out by pressure filt

4.6 From Enlightenment to Romantic thinking

The Enlightenment had typically expressed, on the one hand, the soul and imagination and, on the other, reason and intelligence in terms of incompatible opposites. Not so Delacroix:

What are the soul and the intelligence when separated? The pleasure of naming and classifying is the fatal thing about men of learning. They are always overreaching themselves and spoiling their game in the eyes of those easy-going, fai

8 Governance beyond the UK: The EU

One of the elements invoked in favour of regional devolution involves the significance of regions within the European Union. While some refer to the principle of subsidiarity (governing, when possible, at the local level), as promoted by the EU, as an argument in favour of devolution, others emphasize that regional government improves the prospect of receiving EU regional subsidies. At the moment, there are striking differences between regions within Europe. While some regions have an economi

3.3.2 Enhancing the perceptual system

Magnificently evolved though it is, our sensory system is nothing special. We do not see as well as birds; our hearing is feeble compared to that of bats and some forest-dwelling mammals. Our sense of smell can't compare with that of dogs or pigs. There are many things we don't detect at all – radio waves, for instance.

In one capacity, though, humans are supreme: we have learned to enhance our perceptual systems with instruments. For example, the human eye has only a limited p

12.1 Introduction

Data must be stored somewhere when it is not being manipulated. Modern ICT systems require increasingly large amounts of data to be stored for later use, and it is important that the data can be accessed quickly. Data may be stored on the stand-alone computer's hard disk in the form of files.

You may want to move files from one stand-alone computer to another. In addition, you may want to move files from a device, such as a digital camera, to a computer. These activities require some fo

4.1.3 The receiver

The receiver receives data from the network and manipulates it into a message to send to User 2. Sometimes the receiver may also store or retrieve data.

In the mobile phone communication system, the data received from the network must be manipulated back into sound before being sent to the user. In addition, some mobile phones can store and retrieve data about the user's contacts, so that when a call is received they can translate the phone number of the caller into a name which is then

3.4.4 Law imposes more stringent requirements than ethics

All health care practitioners, including those in CAM, must work within the laws of the country where they practise. Although the law does not always reflect what is considered ethical – indeed, ethical duties may be thought of as higher than legal duties – in most jurisdictions it ensures that practitioners are subject, at the very least, to minimal requirements vis-à-vis respect for users' dignity, user information, confidentiality, and maintaining professional boundaries.

3.4 Myths about ethics

The media portray most ethical issues in highly charged terms, so it can be hard to understand what professional ethics is about, and what the full scope of ethical behaviour amounts to. In short, the media rarely explore the ‘grey’ areas of many ethical decisions. For example, the issue of abortion is viewed as either ‘pro choice’ or ‘pro life’. In this way the following myths about ethics are perpetrated.
