4.1 The grizzly bear There are three activities in Section 4, asking you to summarise information in the form of lists. In the first two, the answers are given but in the third, about the diet of the giant panda, they are not. You are asked to tick off the points in your list as you read on through the section. As you gain more stu 2.4 African Red Slip ware Between about 30 BC and AD 75 the most common type of ceramic tableware in the empire was terra sigillata (often known as Samian ware). This was a shiny red-surfaced ceramic which was first made in Arezzo in Tuscany, Italy and then widely imitated in many areas such as Campania, Rome, southern and eastern Gaul, and Asia Minor. The forms of this pottery were typically cups, bowls, plates and dishes. Beyond the areas where it was produced, the pottery was widely traded and it has been fo 4.1 Three approaches to global environmental change How many ordinary people know that sustainability is the concept that is meant to save the world? How many people who believe in the concept are convinced that it can capture the public imagination? The answer to both questions is ‘not many’. It is easy to lay the charge that the idea has been much talked about in some closed circles, but has no purchase on the public imagination and is little practised. This section takes the three different approaches to global environmental change desc References Conclusion This course has shown you that much of the carbon footprint of an economy is due to the direct and indirect use of energy and consumption of food, goods and services by individuals and households. Hence, what you can do as an individual consumer and/or household member to lighten your carbon footprint can be significant. But communities, business and governments also have a crucial role in tackling greenhouse gas emissions and climate change. After completing this course you should be a 6.3 The role of active citizens and communities Few people agree that individuals should take the main responsibility for tackling environmental issues. For example, in a 2007 poll of over 2000 UK citizens, 70% agreed that the government should take a lead in combating climate change, even if it means using the law to change people's behaviour. However, over 60% disagreed that there was nothing they could do to avert climate change and over half agreed that they would do more if others did more too, although 40% thought that recycling was 1.6 The human impact on the atmosphere: the coming of the industrial age There is no doubt that CO2 is accumulating in the atmosphere. The record from Mauna Loa charts a continuing rise in CO2 concentration since measurements began in 1958, when the level was 315 ppm; the value had reached about 370 ppm by the end of the 20th century, and hit more than 378 ppm in 2004. Important as changes in atmospheric CO2 undoubtedly are (see below), we need to be aware that this is not the whole story of human-induced greenhouse forcing. In par 4.3 The UK experience: competing trends But one striking example does not make an argument. To try to get a fuller and possibly fairer picture of energy use by domestic refrigerators I'd like also to look at the UK experience over the past few decades. To start with it helps to have a feel for which parts of the UK economy use the most energy. The UK Department of Trade and Industry (DTI, 1998), identifies four main economic sectors: domestic (households), industry, services and transport. In 2003 the domestic sector (h 4.2 The US experience: wasteful innovation? In the 1950s and 1960s many industrialised countries experienced a prolonged period of economic expansion which, together with the rise of consumerism, created an increased demand for domestic appliances. With ready access to cheap supplies of fuel, there was little or no incentive for manufacturers or consumers to worry about energy conservation. Nowhere was this more evident than in the US, as the following extract from the influential book Factor Four of the design developments in d 3.3 Greenfreeze: the Greens fight back Some campaigners were not convinced by the arguments of refrigerator manufacturers and suppliers (who also happened to own some patents for HCFCs and HFCs) that the only solution, in the short to medium term, was to use the transitional compounds. They tried to demonstrate that there were practical alternatives. A group of scientists working with Greenpeace International designed a domestic refrigerator based on the use of hydrocarbons, using a mix of propane and isobutane for the refrigerant 1.5 Organising information How confident are you that you know when it is appropriate to cite references (refer to the work of other people) in your written work? 5 - Very confident 4 - Confident 3 - Fairly confident 2 - Not very confident 1 - Not confident at all How confident do you feel about producing bibliographies (lists of references) in an appropriate format to accompany your written work? 6.4 Benefits 7. What are the financial benefits of the proposed change? 8. What are the short-term operational benefits e.g. improvements to the key operations performance objectives? 9. What are the strategic benefits, if any, of the 3.3 Magnetic tape recorders Experiments showed that the use of paper tape coated with iron oxide particles significantly improved the signal-to-noise ratio and enabled a lower tape speed to be used. A plastic-based version of this magnetic tape, developed by the German company BASF, led to the development of a commercial tape recorder with audio characteristics that could nearly match those of the gramophone record, but not at an economical price. Secret work on tape recorders was undertaken by the Germans throug 5.13 Other primary vibrators You saw in the previous two sections that stringed instruments and wind instruments possess primary vibrators that have harmonically related natural frequencies. As a result, these two classes of instruments produce notes that have a well-defined sense of pitch. In this section, I want to briefly introduce you to some primary vibrators that don't have harmonically related natural frequencies. Specifically we shall take a look at a rectangular bar, a circular membrane and a circular plat 2.3 Grice on natural and non-natural meaning Ironically, the word ‘meaning’ has many different meanings. There are four occurrences of ‘mean’ (or ‘meaning’ or ‘meant’, etc.), italicised, in the following paragraph: Roberto's instructor had been mean to put it so bluntly, but she was probably correct that his short legs meant he would never be a great dancer. He turned into the narrow alleyway, meaning to take a shortcut ho 1.1 Introduction An interesting analysis of Napoleon's involvement in Spain is provided by Stendhal in A Life of Napoleon, chapters 36 to 43. Stendhal argues that Napoleon's basic error was to see Spain as susceptible to the imposition by the French of the kind of enlightened reforms which had been welcomed elsewhere in Europe. Stendhal particularises, in a way characteristic of Romantic writers, on what he considers a highly distinctive Spanish national character, which in his view explains the hostil 2.7 Style and language What do we mean when we talk of a particular writer's style? It might help us to think of style as a way of organising and expressing narrative unique to the writer, as distinctive and personal a characteristic as the writer's handwriting or the prints on the fingers holding the pen. Just as no two sets of fingerprints are alike, so no two writers are alike. Writers write in a style that reflects their individual view of the world. The word ‘style’ can generally be used to encompass 2.6 Genre In The Realist Novel Dennis Walder provides you with an extract from a detective novel to identify, and suggests that you'll find this relatively easy because it contains certain features that we expect in such a work. In other words, we each have a mental set of expectations that we use to categorise writing. 1 Why do we read prose fiction? Prose fiction, whether in the form of the novel or the short story, is unarguably the most popular and widely consumed literary genre. One only has to see the proliferation of bookstalls at railway stations and airports, for example, and the predominance of novels over other forms of writing made available in such locations to realise the appeal of fiction. Take a few moments to think about Why we read fiction? What do we hope to gain from reading stories about imag 3.3 Emotion, motivation and action Perhaps one of the most striking features of James's theory is his account of the relationship between emotions and actions. As James points out, this is one aspect of his theory that runs directly counter to our ordinary conception of emotion. Ordinarily, we assume that emotions motivate actions: for example, if someone asked why Larry kicked Bella's bin, we might say that he was motivated by anger – that he did it because he was angry. On James's account, the order of explanation is rever
