3.5 Birth control

The fertility decline in Britain was not the direct result of social policy aimed at reducing the birth rate. The deliberate use of birth control was widely condemned as unnatural and immoral by the medical profession, the church and a wide range of conventional opinion, even though doctors and vicars were the first to limit their own families. There was widespread ignorance about the mechanics of human reproduction and how to control it, but for those in the know there were many methods of c

Referencing is not only useful as a way of sharing information, but also as a means of ensuring that due credit is given to other people’s work. In the electronic information age, it is easy to copy and paste from journal articles and web pages into your own work. But if you do use someone else’s work, you should acknowledge the source by giving a correct reference.

Introduction

This unit will help you to identify and use information in society, whether for your work, study or personal purposes. Experiment with some of the key resources in this subject area, and learn about the skills which will enable you to plan searches for information, so you can find what you are looking for more easily. Discover the meaning of information quality, and learn how to evaluate the information you come across. You will also be introduced to the many different ways of organising your

1 Capturing the oil industry

The oil industry is perhaps the archetypal globalised industry. Dominated by a few multi-national companies, it is highly centralised at the level of corporate power but, like corporations, investment and trade in the oil industry are also highly mobile. The long reach of the global oil economy is a consequence of the distance between the location of significant oil reserves and the location of the major markets for oil. The reserves of oil currently expected to last more than fifty years are

3.2 By medium

We can divide texts up by the medium in which they appear. This is a broad division that is technologically based. It may seem excessively obvious, but it can be quite revealing. For example, different media have different periodicities (frequency of appearances) – most magazines appear weekly or monthly, while newspapers are weekly or daily. Episodes of television programmes are most commonly also weekly or daily, but films appear on a different basis altogether, since, like books or CDs t

6.7 What about alternatives to secession?

We have seen that in principle there are alternatives: cultural autonomy or a form of federalism. There are alternative ways to recognise 'national' identity apart from secession.

One conclusion to arise from this discussion of secession is that we are not cast adrift without any general principles or guidelines. We have also seen how the complexities of the real political world impinge upon poli

6.2.1 Job rewards

Segmented labour market theory views the labour market as systematically differentiating the job rewards achieved by comparable individuals. The high pay of primary workers cannot be explained simply in terms of their higher quality of labour since many secondary workers are capable of performing well, given the opportunity to do so. The labour market is thus seen as a key ingredient in the generation of economic inequality and not a passive mirror of the inequalities which people bring to it

3.2 Poverty as natural/inevitable

There is a construction of poverty that identifies it as a necessary feature of social life: some people will be better endowed, try harder or be more successful than others, and inequality will be an inevitable result (see, for example, Herrnstein and Murray, 1994, who argue that low levels of intelligence are the main determinants of poverty in the USA). Interfering with this natural order of things is dangerous, particularly because it prevents poverty acting as a spur to try harder. This

2.5 Representing weights

A physical quantity such as weight has the property that it can take on any value, not just a finite set of values. For instance, at one time the ingredients in the scalepan could weigh 29.2569427 grams, at another time 125.1234659 grams, at yet another 2805.87625922 grams. It may not be possible for the scales to display such values, but they are physically possible. Quantities like weight whose values can take on any value in this way are said to be analogue.

2.2.3 Positive integers: converting denary numbers to binary

If computers encode the denary numbers of the everyday world as binary numbers, then clearly there needs to be conversion from denary to binary and vice versa. You have just seen how to convert binary numbers to denary, because I did a couple of examples to show you how binary numbers ‘work’. But how can denary numbers be converted to binary? I'll show you by means of an example.

10.1 Introduction

A stand-alone computer receives data from a user by means of input devices. The two most commonly used input devices are the keyboard and the mouse. A computer sends data to a user by means of output devices. Data may be output via devices such as a screen or a printer.

There are many different ways of getting data into a computer. For example, a scanner converts images and texts into a format that can be processed by the computer and displayed on screen. Devices such as t

4.8 Verification

You will, perhaps, by now be getting a sense of the challenge of setting up an identification system on a national scale. However, for many routine purposes, establishing who a person is from an entire population of possibilities is not what is required. Instead what is required is confirmation that the person is who they claim to be. This is verification. An example of verification happens when you collect a parcel from a depot. You are sometimes asked to show your driving licence, pa

5.1 Transmission of electrical signals on wires

In the discussions of newsgathering in the Taylor and Higgins papers, you saw the significance of the development of systems that allowed long-distance transmission of electronic signals. Initially transmission used metallic wires (remember Taylor's reference to the importance of the ‘lines infrastructure’ and his mention of the ‘wire picture’) and later wireless transmission (terrestrial and satellite microwave) became important. In this section I shall look at some aspects of the tr

6.9 Alternatives to the main success scenario

If a use case incorporates a scenario that is significantly different from the main success scenario, you may decide to create a new subsidiary use case. There may even be a need to create more than one subsidiary, depending on what happens in different circumstances. For example, when making a reservation in a typical hotel the receptionist would first determine whether the guest was already known to the hotel (among other advantages, this would speed up the reservation process since re-ente

General introductions to the philosophy of mind tend to be ahistorical and vary greatly in accessibility and coverage. E.J. Lowe covers virtually the whole range of topics in his An Introduction to the Philosophy of Mind (2000). For less coverage but more detail see Jaegwon Kim's slightly more advanced but excellent Philosophy of Mind (1996). Tim Crane's The Elements of Mind (2001) is another very good but more advanced introduction to current issues and contains one of t
