Diagrams for understanding are best developed within the creativity phase, though sometimes you can go straight on to using a diagram more suitable to the connectivity phase. Most diagrams for understanding begin at the centre of the sheet of paper and work outwards. Buzan's (1974) spray diagram is built up from an initial idea with its branches; these branches have their own branches and so on until you reach the detail at the end of each twig. This technique is particularly useful fo

In Section 1 we discuss the idea of a set and describe some ways to define sets. We illustrate our discussion with sets of numbers and with geometrical sets of points in the plane. We also explain how to check whether two given sets are equal and whether one set is a subset of another. Finally, we introduce the set operations of union, intersection and difference.

To make an analogy with the now outmoded vinyl record, if â€˜the fear of crimeâ€™ track is the A-side of this hit record, the track on the B-side is â€˜the fascination with crimeâ€™. Fascination may seem an unusual word to associate with the pressing social problem of crime, given its harmful and destructive consequences. After all, we often associate being fascinated with being allured or charmed by someone or something. How might such feelings be associated with those fearful things we call

The Changing Image of the City
The image and structure of a town are constantly subject to a dynamic process of change and continuity. Visual material, such as photographs, historical maps, town plans, drawings and prints, show us the impact of these changes on the image of a town. The main point of departure of this study stems from the question of how this process of change and continuity is visually detectable in a town or city. The fact that the ideas about the appearance of a city (gradually) change, can be read from the

Introducing Health Sciences: Breast Screening
Most women share a common fear - breast cancer. From the age of 53, they are invited by their GP to have a mammogram - a procedure that screens the breast for any abnormalities. But many women don't understand what this involves. The 3 video tracks on this album explain why it is important to have a mammogram, hear from women being screened, show the processes involved and demonstrate what happens should an abnormality be found. This material forms part of The Open University course SDK125 Intr

This scenario sees African culture surviving following the Roman conquest, and where Roman culture is visible it does not replace preexisting practice. Here we might imagine a laissez-faire attitude on the part of the Roman state, allowing the conquered people to carry on in their previous ways and the African people not needing to, or wanting to, adopt Roman customs, practices, forms of representation and cultural identity. In this model we might expect to find Roman and African trait

This extract provides you with examples of instances when the House of Lords has not followed its own previous decisions.

This may be the first time you have read the name of a legal case. Case names are written in a particular style. For example, t

One of the characteristics of 'good' information is that it should be balanced and present both sides of an argument or issue. This way the reader is left to weigh up the evidence and make a decision. In reality, we recognise that no information is truly objective.

This means that the onus is on you, the reader, to develop a critical awareness of the positions represented in what you read, and to take account of this when you interpret the information. In some cases, authors may be e
