Combating air pollution
What’s in the air you breathe and how do you know it’s safe? Pollution control is vital since nobody has a choice when it comes to inhaling the air around them. This album introduces the scientific processes behind air monitoring and air quality management. The five video tracks explore the nature of pollution arising from different forms of transport, and look at how data is interpreted and how pollutants can be minimised. To complete the album, Senior Lecturer Rod Barratt explains the cho

3.1 Introduction

Section 2 used some simple examples to illustrate chemical periodicity. But how can we explain such periodicity? The answer lies in the way that the electrons in atoms are arranged about the positively charged nucleus. In chemical reactions, atoms change partners. We know that the outsides of atoms consist of electrons, so contact and connection between atoms is likely to take place through their electrons, and in particular, through the electrons in their outer shells. So similarities in

5.1 Managing relationships

You should now understand that markets and the customers within them are the responsibility of all managers within an organisation. An organisation needs to identify what will create extra value for its customers, and design a value-driven operating system that will concentrate all its efforts on producing it. This process of going to market involves the organisation in managing the relationships between itself and its customers and competitors, and also in the co-ordination of the organisati

8.1 Balanced argument

In many instances, we are not just concerned with arguing a particular case or taking a particular point of view, we are interested in looking at all sides of an issue and producing a balanced argument. This can be helpful in drawing conclusions on an issue.

5 Conclusion

The issue of climate change draws attention to the power of human activity to transform the planet in its entirety, and it is brought into sharp focus by the predicament of low-lying islands like Tuvalu. As we have seen in this unit, the issue of rising sea level and other potential impacts of changing global climate also point to the transformations in the physical world that occur even without human influence. Oceanic islands provide a particularly cogent reminder that the living things wit

Breaking News: The Changing Relationship Between Blogs and Mainstream Media
Panel discussion during the Oxford Social Media Convention 2008 on whether social media necessarily threaten traditional news media, and what, if anything they may have to offer in return. Among the traditional media, blogs and other contributions to citizen journalism have for a long time been regarded as posing a significant threat to quality news reporting, whilst the global recession has shown that the threatened failure of high quality local and regional media outlets was not a groundless f

The interplay between leading and learning
Leadership in learning contexts is not confined to those who have it as part of their job title. Everyone has opportunities for leading - be it of learners, of colleagues in curriculum or project development, or more formally. Everyone also has the opportunity for learning. This free course, The interplay between leading and learning, explores the complex set of interactions between those involved for example, teachers and pupils, trainers and trainees, youth workers and young people.

1.3.5 Corporate connections

As I mentioned in Section 2, what was happening in the factories of overseas contractors was said to have appeared remote to most, if not all, the chief executive officers of the clothing multinationals in the 1980s. Overseas contractors were selected on the basis of market price, quality and reliability, not on whether forced or child labour happened to be employed to stitch the product together. However, all that changed in the early 1990s when the geographical ties between the big retailer

#391: Not the highest bidder: China’s crony capitalism and the large scale looting of public asset

Governance expert Prof Minxin Pei describes how collusion between China’s political and business elites have resulted in the privatization of public assets for enormous personal gain. He also explains why the current crackdown on corruption is but a band-aid and that a free media and liberal democracy may be the key elements to a lasting solu

1.2.3 Basic principles

Whatever resource you choose to use to find information on the internet, many of the same principles apply. Each source that you use will probably look quite different from the one you tried before, but you'll notice that there are always features that are similar – a box to type your search terms in, for instance, or a clickable help button. Different resources refer to the same functions using different terminology, but the principles behind them are exactly the same. The trick is to chec

4.7 Build prototype/demonstrator

The physical models we talked about earlier are prototypes or demonstrators of a sort. However, for the purposes of making a clear distinction in the process, I'm referring here to prototypes or demonstrators as functioning preliminary models of the essential finished product or construction or service, bringing together all the elements of the design that may or may not have been previously physically tested (Author(s): The Open University

Animals at the extremes: Hibernation and torpor
Hibernation is an ingenious adaptation that some animals employ to survive difficult conditions in winter. This free course, Animals at the extremes: Hibernation and torpor, examines the differences between hibernation and torpor, and discusses the characteristic signs of hibernation behaviour. It explores the triggers that bring on hibernation, and whether internal signals or external season cues are predominant. It also examines the physiological adaptations that occur in hibernating animals.

First-order differential equations

The subject is developed without assuming that you have come across it before, but it is taken for granted that you have a basic grounding in calculus. In particular, you will need to have a good grasp of the basic rules for differentiation and integration.
