2.3.1 Geological mapping of coalfields

Coalfields can be divided into two categories: exposed coalfields, where the coal-bearing strata outcrop at the surface, and concealed coalfields, where they are hidden beneath younger rocks. Exposed coalfields can be defined with considerable precision by surface geological investigations; indeed geologists recording field data still represent the cheapest exploration 'tool' available to the coal industry.

In populated regions, the locations of coal outcrops are well know

2.3 Contingent model of accounting change

The totality of the accounting rules in any one country at any one time represents an accumulation of rules that have been brought in over many years (even centuries, in the French case). In remembering that, it becomes clear why the rules are sometimes inconsistent: they have been put together by different people, at different times, and in the face of different circumstances and priorities. It also makes clear why it would be optimistic to expect close comparability between national sets of

5.4 Product champion

Throughout the development of this innovation Edison endeavoured, by means of persuasive argument and demonstrations of progress, to convince those people who were in a position to help further the success of the electric light that it had great potential. These people included financiers who could provide capital for more research and development, industrialists who might install it in their factories, and politicians who might agree to the large-scale city installation of a lighting system.

4.7 Summary

Water in its 'natural' state supports a complex, yet fragile, ecosystem. The ability of natural watercourses to sustain aquatic life depends on a variety of physical, chemical and biological conditions. Biodegradable compounds, nutrients and dissolved oxygen must be available for the metabolic activities of the algae, fungi, bacteria and protozoa which are at the lowest level of the food chain. In addition, plant and animal growth cannot occur outside narrow ranges of temperature and pH. Susp

Social work learning practice
This free audio course, Social work learning practice, focuses on the importance of people's backgrounds and experiences in the field of social work. It identifies the diverse ways in which service users and social workers define themselves, helping you to understand how the two groups perceive each other and relate successfully to each other. An understanding of how people make sense of their experiences will help you to define yourself, and your own place within the process.Author(s): Creator not set

3.4.3 Respecting autonomy is the foremost ethical principle in health care

Some commentators believe the pendulum has swung so far in favour of respecting autonomy that it leaves little scope for users to be passive recipients of healing. The desire to make each user an active participant in their own healing process can make it hard, or even impossible, for a user to refuse to engage in active decision making, and leave the decision to the benevolent practitioner. In this case, the user may waive his or her rights, by choosing not to be kept informed about changes

1.1 Introduction

There are many environmental reasons why coal is a rather undesirable source of energy. Burning it introduces large amounts of gases into the atmosphere that harm the environment in a variety of ways, as well as other, solid waste products. Coal extraction leads to spoil heaps and mines that scar the landscape, land subsidence that affects roads and buildings, and in some cases water pollution.

With apparently so little going for it, why do we rely so much on coal to meet our energy nee

2.6 Underground mining

Coal extraction is of course less straightforward using underground mining techniques. The associated costs are higher, and these begin with the sinking of two shafts, an 'upcast' and a 'downcast' shaft for ventilation (Figure 22). Sinking these to a depth of a kilometre may take a few years and during this time,

Managing Creativity and Creative Management
As the Creative Industries become a more important part of the global economy does the stereotype of the creative genius still persist? Do we need to rethink our ideas on creativity and understand how it works more clearly? Dr Chris Bilton, Centre for Cultural Policy Studies, argues that organisations need to start thinking about creativity as a process and begin adapting traditional business strategies to develop a creative approach to management.

1.12.2 Constructing discursive spaces

Finally, the notion of discursive space draws attention to the broader social practices which construct such spaces. Thus social scientists and discourse researchers have been interested in the practices of production of newspapers and the media and in the ways in which economic and technological developments construct discursive spaces. E-mail, the internet and computer-mediated communication are good examples of how changing practices produce new spaces which construct new kinds of discursi

It gives estimates of the cumulative effect since pre-industrial times of the various climate change agents, with the contributions expressed in terms of radiative forcing. Note that the figure also includes yet another device for communicating the IPCC's confidence in a particular finding - an indication of the 'level of scientific understanding' that accompanies each estimate.
