The prerequisite requirements to gain full advantage from this unit are an understanding of ordinary differential equations and basic familiarity with partial differential equations. This unit is an adapted extract from the course Mathematical methods and models (MST209 1.3 Designing alternative programmes and curricula Assuming that both the content of mathematics and the processes need to be included in programmes and curricula, the problem becomes one of how a suitable curriculum can be structured. One possibility is to construct a very specific curriculum with clearly defined objectives for both content and processes separately, and possibly with suggested learning activities. However, content and process are two complementary ways of viewing the subject. An alternative is to see the curriculum in Learning outcomes After studying this unit you should: be able to perform basic algebraic manipulation with complex numbers; understand the geometric interpretation of complex numbers; know methods of finding the nth roots of complex numbers and the solutions of simple polynomial equations. 1.6.3 Mailing lists and newsgroups Mailing or discussion lists are email-based discussion groups. When you send an email to a mailing list address, it is sent automatically to all the other members of the list. The majority of academic-related mailing lists in the UK are maintained by Jiscmail. You will find details of joining these mailing lists on the Jiscmail website. Mailing lists are useful for getting in touch with like-minded colleagues. They are also handy for keeping up to date with current thinking and research 1.5.9 Plagiarism Referencing is not only useful as a way of sharing information, but also as a means of ensuring that due credit is given to other people’s work. In the electronic information age, it is easy to copy and paste from journal articles and web pages into your own work. But if you do use someone else’s work, you should acknowledge the source by giving a correct reference. Taking someone's work and not indicating where you took it from is termed plagiarism and is regarded as an infringemen 1.5.6 Copyright – what you need to know An original piece of work, whether it is text, music, pictures, sound recordings, web pages, etc., is protected by copyright law and may often have an accompanying symbol (©) and/or legal statement. In the UK it is the Copyright, Designs and Patents Act 1988 which regulates this. In most circumstances, works protected by copyright can be used in whole or in part only with the permission of the owner. In some cases this permission results in a fee. However, the UK legislation incl 1.5.5 Social bookmarks If you find you have a long unmanageable list of favourites/bookmarks you might like to try social bookmarks as an alternative.

Try applying these and see if you can reduce your information overload.
1.5.3 Desktop search tools Finding your paperwork or electronic files can be a problem. You may find that even if you do have some sort of filing system, your structure soon gets quite large with files in multiple locations, which can be hard to navigate. You may find yourself making arbitrary decisions about which folder to place a document in. It may make sense now but in the future, when you look where you think it should be, it’s not there. At times like this you may resort to the search command from the Wi 1.5.2 Ways of organising yourself How do you organise yourself?

Some of the decision makers, depending on the context of your search might be: Does it have full text? Does it cover the right subject? 1.2.2 Choosing keywords Keywords are significant words which define the subject you are looking for. The importance of keywords is illustrated by the fact that there is a whole industry around providing advice to companies on how to select keywords for their websites that are likely to make it to the top of results lists generated by search engines. We often choose keywords as part of an iterative process; usually if we don't hit on the right search terms straight off, most of us tweak them as we go along based on t 5 Conclusion – new ways of looking at the world There is a variety of new approaches or terms that are interlinked, and have been prominent throughout this book. All of them have played a part in this book's journey through the scientific, political, philosophical and social implications of climate change. Governance of climate change is about: decision making under uncertainty; understanding and representing vulnerability even when vulnerabilities are difficult to assess or unknowable; and making every aspect of human 4.4 Signing everyone up to sustainability The proposers of step-by-step progress towards sustainability would include in their plans many of the ideas proposed in the previous two subsections. However, what distinguishes this group is that they stand in the middle of the scale between faith in unfettered business voluntarism and a conviction that radical transformations are required. Their incrementalism is reflected in the kinds of pragmatic solutions they propose; their radicalism shows in the way they think about new roles and pro 5.1 Actions for lighter living Nobody made a greater mistake than he who did nothing because he could only do little. (Edmund Burke, 1729–1797) If you want to consider how to further lighten your carbon footprint, you may need more detailed information on the effect of technical and behavioural actions not covered by the carbon calculator, or included only as a part of other actions. It's important to understand whic 2.2.2 Temperature changes over the past millennium One of the most striking images in the IPCC TAR is reproduced (in adapted form) in Figure 24. Together, these two temperature records tell a compelling story, crystallised in our earlier quotes from the SPM. So let's just pause to take a closer look at each of them. Introduction This unit explores the topic of climate change and global warming. We will begin by exploring how the Earth’s global mean surface temperature is determined through a global “balancing act” of the rate of energy that comes from the Sun and the rate at which the planet returns that energy into space. We will also discuss the natural greenhouse effect, and how this contributes to a balanced global climate. We will then go on to consider the human impact on the atmosphere, including the imp 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. The Thing – that is, the repercussions of the eighteenth-century European industri
