2.1 Issues of responsibility

The aftermath of the 2004 Indian Ocean tsunami saw an unprecedented aid effort to assist the affected regions. In the early days after the disaster, pledges of financial assistance from overseas governments were often outstripped by the generosity of their own populaces. This was a case when ordinary people around the world saw and were moved by the tragic circumstances of others far away (Rose, 2006), and they responded with gifts of money and provisions, and even with offers of their own sk

4.1 Uniting the developing countries

Several attempts have been made to form a united front of developing countries to negotiate a better deal at the WTO. They have met with little success because there are substantial conflicts of interest between them, for example between agricultural importers and exporters, and between small countries and those larger developing countries that have been able individually to use the lure of opening their markets to get a better deal from developed countries. Conflicts of interest arise too be

3.2.1 Social disruption

In return for being granted enhanced market access by developed countries, which turned out to be somewhat illusory, developing countries agreed to open up their own markets. Indeed, for supporters of the UR, this was its biggest achievement. One of the central propositions of economic theory is that under certain conditions free trade is beneficial to a country – but there are inevitably winners and losers. As a country adjusts to free trade, some sectors of the economy advance, while othe

3.1.1 Agriculture

According to the UR Agreement on Agriculture, import quotas were to be abolished, but since no country was prepared to expose its farmers abruptly to the rigours of free trade, quotas were to be replaced by ‘equivalent’ tariffs, which were to be reduced over time. However, the calculation of equivalent tariffs is subject to wide margins of error, and since it was left to each country to determine its own tariffs, most were set at extraordinarily high levels – exceeding 200 or even 300 p

1.1 The WTO

The Ministerial Declaration adopted by WTO members at Doha on 14 November 2001 fails to address the most pressing needs either of the poorest countries or of the world's most vulnerable communities. This means that the people who most need a share in global prosperity are still those least likely to obtain it.

Energy policy and climate change
The 2009 United Nations Climate Change Conference in Copenhagen presents a new focus for international debate and decisions about energy and its use. What are the countries of Western Europe and Scandinavia doing to promote sustainable energy production? Just how different will the future energy map of Europe look? And is energy policy principally a scientific issue or a political one? This album contains a series of films exploring energy policy in various countries around Europe in 2006, frame

How do you start to design a product? Can drawing techniques be learned? And why is modelling such a useful technique? This album introduces the basic skills necessary to communicate ideas on paper, as well as revealing the step-by-step processes for making three-dimensional models of objects, showing perspective in drawings and sketching complex objects. It also features a case study of the Strida folding bicycle, an idea taken from initial drawings to marketed product. This material forms part

Water Treatment
Do you think about where your water comes from? In the UK each of us uses an average of about 150 litres of water per day! The seven video tracks in this album consider issues of demand and quality in water supply as well as treatment processes. They give information on methods of minimising waste, emergency water treatment and effluent control.

Noise Pollution
How do your ears work and what kind of sound levels can damage your hearing? The five video tracks in this album explain basic concepts such as units of noise, sound insulation and noise control. Car manufacturers like Lexus have developed the quiet car, but this kind of technology benefits the driver, not the people living beside busy roads. Locals from a Derbyshire village explain how the construction of the A50 has affected their lives. The Transport Research Laboratory analyses tyre noise on

Nepal is one of the poorest countries in the world, so just how has it managed to develop a wireless network and promote innovation? This collection explores how Nepal has developed its digital technological infrastructure, how it is still developing from a complex political background and gives a sense of how different cultures around the world relate to digital technology. The videos look at the country's recent history, with particular focus on education, health, language and the economy. Th

Introduction

In this course we examine one factor that very often seems to be found skulking around close to problems and solutions: temperature.

Almost whatever we do, wherever we are, temperature changes. Stay in the same spot and you'll find daytime and night-time temperatures can be markedly different. You may even find significant changes in temperature during the day. When moving you can encounter more rapid variations. For example, an aircraft might leave a tropical runway where the air tempe

Introduction

The optimistic approach to a problem is to view it as a challenge and an opportunity – a chance to make progress. In this course, the nature of problems is explored by looking at the way they are used as a stimulus for finding solutions. It is presumed from the start that you want to be involved in the process of finding solutions and that you are not expecting simply to be given the answers.

One example that is investigated in this course concerns how to devise lighter bicycle frames

4.1 Characteristics of processes activated by thermal energy

This is a long section and needs to be studied carefully. Keep your eye on the overall goal of seeking useful thermal effects on which to base devices.

This section continues the discussion of heat at an atomic level. You will need this background to appreciate the characteristics of processes activated by thermal energy – for example, the softening of glass in a gas flame, the diffusion of atoms through solids, the electrical conductivity of ceramics, and many chemical reactions.

3.2.1 Group context

Probably the two most important features of a formal work group are the task or objectives assigned to it and the environment in which it has to carry that task out. It is important that a work group be given a realistic task and access to the resources required to complete it, and that the people in the group feel that the task is worth accomplishing, i.e. that it has some importance.

When a group fails to make headway, one common cause is that its brief covers several tasks, some of w

2.8 Why do (only some) teams succeed?

Clearly, it is not possible to devise a set of rules which, if followed, would lead inexorably to team effectiveness. The determinants of a successful team are complex and not equivalent to following a set of prescriptions. However, the results of poor teamworking can be expensive, so it is useful to draw on research, experience and case studies to explore some general guidelines. What do I mean by 'team effectiveness'? – the achievement of goals alone? Where do the achievements of individu

Conclusion

The building blocks of a basic optical-fibre communications link are the modulated light source, the fibre and the detector. There are choices to be made between different types of light source and fibre, with trade-offs between cost and performance. For example, for high signalling rates over long distances single-mode fibre will be used with a single-mode laser (possibly with external modulation) operating in the 1550 nm window, whereas for short-distance links operating at lower signalling

4.4.1 FTTCab, FTTC, FTTB and hybrid coaxial fibre

The equipment needed at optical-fibre transmitters and receivers (lasers, photodiodes and the associated electronics) is more expensive than the equivalent for transmission over copper cables. With FTTH this equipment is needed in every home, and a substantial cost reduction is possible with schemes where the fibre doesn't go all the way to the home, but stops short, and copper links run from a shared fibre to several homes (Author(s): The Open University
