Water in Ethiopia
In Ethiopia, 65% of people don’t have access to clean drinking water. In this album we take a glimpse at the struggles Ethiopians go through each day, just to survive. We look closely at the different methods used to improve the quality of life in the rural highlands as well as the conflict between neighbouring farming villages attempting to share the same water supply.

9.2 Marking up a text

Although you might not think of this as note-taking, marking the text as you read can be a very useful part of the note-taking process. You can do this by using a highlighter pen, by underlining key points or by making notes in the margin. However, try not to overdo it and only highlight important points.

6.2 ‘No-choice’ dispersal

Dispersal as a strategy aimed at resolving tensions, avoiding ‘concentrations of aliens’ and preserving ‘ethnic balance’ and ‘cultural homogeneity’ is not a new idea, but one proposed for the settlement of successive groups of refugees, and indeed immigrants, since the 1930s, and also used in the 1960s and 1970s in relation to housing and education (Lewis, 1998). The government's asylum dispersal policy of 1999, intended to ‘ease the burden’ of the south-east of England, was b

6.2 Working with bits

You may have met the term bit, perhaps in connection with computers. The term ‘bit’ is also important in communication systems. It is an abbreviation for ‘binary digit’. A binary digit can have just one of two values: it can be either 1 or 0. Pulses can be represented by 1s and 0s, that is, as bits, and so it is convenient to think of streams of 1s and 0s being conveyed along the communications link.

The rate at which the 1s and 0s are conveyed is known as the data rat

2.1 England

England played a dominant role in the medieval history of Britain, and the history of the UK is undoubtedly the history of the political and cultural power of England in comparison to Scotland, Wales and Ireland. In the making of the UK, each component nation played a different role: the English and Scottish kingdoms, the incorporation of Wales into the English Crown, and the subjugation of Ireland. The making of the UK was complex and fraught with violent confrontations, particularly virule

1.3 Overview of ‘normality’

Before we can specify what might be ‘abnormal’, we must first have a clear idea of what we mean by ‘normality’. However, within psychology this is much more difficult than it first appears. As our discussion has shown, psychological ‘normality’ can be defined in terms of:

  • what is ‘average’ or ‘typical’ with respect to statistical frequency;

  • ‘lack of disability’ – where ‘normality’ is defined by reference to

5.15 Intellectual property and patents

At any stage of the innovation process, from invention to diffusion, a bright idea with market potential can be a target for unscrupulous copying. Or, as you've seen with simultaneous invention, people might be working on similar ideas in parallel and the origins of inventive ideas might be difficult to identify with precision. So it is sensible for inventors to establish their claim to a particular invention and to protect it against unauthorised exploitation by others.

2.1 Geometric shapes – triangles

This section deals with the simplest geometric shapes and their symmetries. All of the shapes are two-dimensional – hence they can be drawn accurately on paper.

Simple geometric shapes are studied in mathematics partly because they are used in thousands of practical applications. For instance, triangles occur in bridges, pylons and, more mundanely, in folding chairs; rectangles occur in windows, cinema screens and sheets of paper; while circles are an essential part of wheels, gears a

Introduction

This unit will help you understand the expressions social construction and social constructionism. These terms are used in the study of the Social Sciences and, in particular, in relation to Social Policy. The materials are primarily an audio file, originally 28 minutes in length and recorded in 2001.

This material is from our archive and is an adapted extract from Social policy: welfare, power and diversity (D218) which is no longer taught by The Open University. If you want to

Diversity and difference in communication
Interpersonal communication in health and social care services is by its nature diverse. As a consequence, achieving good or effective communication – whether between service providers and service users, or among those working in a service – means taking account of diversity, rather than assuming that every interaction will be the same. This unit explores the ways in which difference and diversity impact on the nature of communication in health and social care services.

Considering these findings alongside the statistical data and our personal stories, we can draw some conclusions about the production and reproduction of knowledge about refugees and asylum seekers through research:

1.3 Framing nature matters as systems

Much of what is considered Nature is often codified as ‘systems’ – natural systems, ecosystems, ecological systems and/or environmental systems. Systems thinking is an active cognitive endeavour to conceptually frame reality. A key feature of framing Nature in terms of systems is the appreciation given to the multiple interrelationships and interdependencies that exist in the natural world.

1.5.1 The co-production of meaning

The third sense in which discourse is a social action refers to the origins of meanings. Meaning emerges from complex social and historical processes. It is conventional and normative. We have some idea what it signifies to say Prince Charles is a proud man because we are members of a speaking community and culture which has agreed associations for ‘proud man’. We draw on those to make sense. Meaning is also relational. Proud signifies as it does because of the existence of other t

16.8 Linking data

We now have two sets of data held by the supermarket: the data about its own products and the personal data about customers. Individually, each of these two sets of information has important uses. However, when they are linked, they provide a very powerful tool for the supermarket.

The personal data from a loyalty card scheme can be used to compile targeted mailing lists, because data about your purchases can help build up a profile of how you spend your money. For example, the supermar

2.2 Converting units

A great advantage of the metric system of units is that conversion between units within the system is particularly easy. For example, ‘£1 is worth 100p’ is converting one pound into pence. To convert pounds to pence, you multiply by 100. So £2 is 200p, and £2.63 is 263p. (Remember that to multiply by 100, you move the digits two places to the left in the place value table.)

To convert from pence to pounds, you need to reverse this process, i.e. to divide by 100 (moving the

1.10 Religion and the individual

How formal or informal, how personal or impersonal, how loose or how tight, how casual or demanding the religious community is will depend on the form of religion, the extent to which it is enforced and the level of the individual's commitment to it. It is worth remembering that just as people have certain expectations of religion, religions tend to have certain expectations of adherents. The sociologists Rodney Stark and Charles Glock (1968) have argued that although religious organizations
