Introduction
In this unit you will be introduced to a variety of Delacroix’s work and see how his paintings relate to the cultural transition from Enlightenment to Romanticism. You will study Delacroix’s early career, his classical background, the development of Romantic ideas and their incorporation into his work. You will have the opportunity to study some of his most important paintings and compare them to works favouring a Neoclassical approach. You will also be able to see how his themes, subjects

Models are mechanisms for communication. This unit looks at what a model is and what the process of modelling is about. The techniques discussed here are applicable to a wide range of systems and have one thing in common: they are all commonly used diagramming techniques. The five techniques are: data flow diagrams, use case modelling, activity diagrams, entity–relationship diagrams and state machines.

Introduction

This unit is taken from Portales, a language course that concentrates on Spanish as a tool for communication, but it also provides some insights into Hispanic societies and cultures through authentic printed and audio materials. It will be of interest to all those who want to improve their language skills in order to communicate more easily and effectively in Spanish. This unit focuses on public spaces and how to get by in a Hispanic city.

Introduction
Following on from the advances made in diagnosing disorders using genetic testing, this unit looks at the possibilities for genetic therapies. Two approaches to gene therapy are discussed: correcting genes involved in causing illness; and using genes to treat disorders. Before closing on a discussion of the issues around 'designer babies' somatic gene therapy and germline gene therapy are discussed.

Introduction
In this unit we will examine a range of Napoleonic imagery by David, Gros and a number of other artists, beginning with comparatively simple single-figure portraits and moving on to elaborate narrative compositions such as Jaffa and Eylau. In so doing, we will have three main aims: to develop your skills of visual analysis, to examine the relationship between art and politics and to introduce you to some of the complex issues involved in interpreting works of art.

The fascinating phenomenon of superconductivity and its potential applications have attracted the attention of scientists, engineers and businessmen. Intense research has taken place to discover new superconductors, to understand the physics that underlies the properties of superconductors, and to develop new applications for these materials. In this unit you will read about the history of superconductors, taking a brief look at their properties. You will also learn about modelling the propertie

Introduction

Sweatshops and the exploitation of workers are often linked to the globalised production of ‘big brand’ labels. This unit examines how campaigners have successfully closed the distance between the brands and the sweatshops, while others argue that such production ‘kick starts’ economies into growth benefiting whole communities.

1.1.1 Introduction

Many of the smaller branded goods on sale to consumers in Europe and North America – the latest in clothing and footwear or the smart toys and electronic gadgets on offer – are made in factory ‘sweatshops’. Found in the backstreets of modern, Western cities, but more often than not a feature of the poorer parts of the world, factory sweatshops are an integral part of today's global economy. Increasingly, as you can see from Author(s): No creator set

1.1.3 Introduction continued

The difficulty perhaps is that things which happen at some distance from the everyday routine of our lives are often hard to place or connect with. Moreover, it has to be said that not everyone views factory sweatshops in quite the same way as groups such as Oxfam, or indeed endorses their negative claims about the use of cheap labour in places such as East Asia. For that is what the statements of such groups are: claims. And they are far from uncontroversial.

In fact, it is poss

1.2.1 Introduction

Looking back over the 1970s, it is perhaps hard now to appreciate just how dramatic were the changes to the global map of industry taking place at that time. As more and more of the world's industry shifted from the affluent nations to the poorer, less developed countries in search of a cheaper labour force, the global economic map had to be redrawn to take account of the borders crossed and the distances traversed by firms from wealthier countries seeking to generate higher profits by reloca

1.3.1 Introduction

Holding up the East Asian success story as the way forward has, as I indicated above, little appeal for the antisweatshop movement. For its members, a different image comes to mind of thousands of workers eking out a living from the numerous sweatshops which dot that part of the world: one that involves the perpetuation of poverty wage levels, the use and abuse of poor communities, and the constant taking advantage of what is ready to hand, followed by withdrawal and abandonment. What they se

1.4.1 Introduction

Up to now I have focused on the claims of the antisweatshop movement and the counter-claims of those who contest the purely negative conclusions drawn about the exploitation of another country's poor. To that end, I have, at various moments, touched on issues of demands to take responsibility: whether, for instance, responsibility for sweatshops should be divided up in some way between all those connected to the market system which gives rise to them, or placed firmly at the door of the big r
