9 Summary
Active galaxies provide a prime example of high energy processes operating in the Universe. This unit gives an overview of active galaxies, including the supermassive black holes that power the engines at their centres, and the emission processes by which we detect and study them. It also gives practice in mathematical techniques for analysing data and theoretical models.
9 Wildebeest migration
From the mouse-deer to the elephant, plant eaters come in all shapes and sizes. But how do they manage to flourish on a salad diet? In this unit we will examine the special features that allow them to extract their nutrients from leaves, and see how some plants protect themselves from these predators. This is the fourth unit in the ‘Studying mammals’ series.
8.3 Shortage of minerals
From the mouse-deer to the elephant, plant eaters come in all shapes and sizes. But how do they manage to flourish on a salad diet? In this unit we will examine the special features that allow them to extract their nutrients from leaves, and see how some plants protect themselves from these predators. This is the fourth unit in the ‘Studying mammals’ series.
8.2 Protein shortage
From the mouse-deer to the elephant, plant eaters come in all shapes and sizes. But how do they manage to flourish on a salad diet? In this unit we will examine the special features that allow them to extract their nutrients from leaves, and see how some plants protect themselves from these predators.

5.3 Hindgut fermenters

James Clerk Maxwell (1831-1879) is arguably the father of electromagnetism, and unarguably one of the greatest physicists ever. Einstein called Maxwell's equations 'the most important event in physics since Newton's time, not only because of their wealth of content, but also because they form a pattern for a new type of law'. This unit will examine Maxwell's greatest triumph, the prediction that electromagnetic waves can propagate vast distances through empty space and the realisation that light

7 The jury The jury system has existed in Britain since the eleventh century, although its functions have changed over the centuries. The first juries very often acted as witnesses reporting on events they knew about. Modern juries should know as little as possible about the case before the trial and are mainly used in criminal trials in the Crown Court. Their role in the Crown Court is to listen to the evidence and decide the guilt or innocence of the accused based on the facts presented to them. They

4.2 Capitalism – naturally
Human societies have to take urgent action to end their dependences on fossil fuels. We have to alter the whole path of our development and decision making in order to make our societies both environmentally adaptable and sustainable. This unit takes on the task of trying to chart some of the ways in which it might be possible.
2.4 Act 5, Scene 2: Faustus's last soliloquy
What does Christopher Marlowe's Doctor Faustus tell us about the author and the time at which the play was written? This unit will help you to discover the intricacies of the play and recognise how a knowledge of the historical and political background of the time can lead to a very different understanding of the author's intended meaning.
6.2.3 Groups The large group portrait came to commercial prominence in the 1880s, probably as a result of the widespread introduction of dry plate negatives. These negatives could be bought ready made over the counter. They did not require immediate processing and they reduced exposure times significantly. The group portrait involved the production of a single negative and a potential sale to each member of the group. Customer costs were kept low without injury to the photographer's profits.

1.6 Summary
Improvisation and composition are words frequently used in the western world to describe the creation of music. But are they really two distinct processes, or are they aspects of the same phenomenon? In this unit we will explore the relationships between the two using examples of Asian music to help us clarify the concepts.

Activity 6: Hofstede's four dimensions of culture
We know that culture guides the way people behave in society as a whole. But culture also plays a key role in organisations, which have their own unique set of values, beliefs and ways of doing business. This unit explores the concepts of national and organisational culture and the factors that influence both.
1 Donor motivation
Legacy fundraising, big-gift seeking are all part of the professional fundraiser's role. This unit will help you to gain the skills necessary to persuade individuals to become donors. How do you change people's ideas about methods of giving, moving them from casual street donations to regular direct debit giving?
2.2 Scotland Having enjoyed political independence until 1707, the survival of many of Scotland's institutions – notably its systems of law, religion and education – after Union with England contributed to the preservation of its singular identity. The different way in which Scotland was incorporated into the UK, through a monarchical take-over rather than by conquest (as was the case in Wales and Ireland), may account for the lesser impact the development of the UK exerted on Scottish distinctiveness
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 domination of the English nation over those of 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, particu
