2.4 Ownership, control and ideas about the body

This section focuses on the extent to which a person becomes invisible when a practitioner rigidly adheres to a specific view of health and disease, and fails to accept that others (specifically the person they are treating) may have different ideas about illness or, indeed, about their body. The imposition of a fixed view of illness and disease can be extremely disempowering for people seeking help.

4.3 Conclusion

Social work practice is based upon assessments of situations and decisions about strategies to be adopted. Sometimes there can be a tension between the law and working within social work values; the law provides the framework for practice. In the next section you are going to examine the legal structures and processes within which social work skills are applied.

1.4 Rights

Rights is a word that is used in different ways. Lawyers use it to indicate that a person is entitled to something, for example not to be dismissed unfairly from their job or to sue for damages if they have been sold faulty goods. Others sometimes talk of rights when they are making a moral claim, for example that they ought to be allowed to demonstrate or that a particular law is unjust or unfair. In this course we use rights primarily in the first sense, i.e. when we are talking about the a

4.4.2 Geothermal energy

Geothermal energy is another renewable source that is not derived from solar radiation. As the name implies, its source is the earth's internal heat, which originates mainly from the decay of long-lived radioactive elements. The most useful geothermal resources occur where underground bodies of water called aquifers can collect this heat, especially in those areas where volcanic or tectonic activity brings the heat close to the surface. The resulting hot water, or in some cases steam, is used

4.3.2 Wave power

When winds blow over the world's oceans, they cause waves. The power in such waves, as they gradually build up over very long distances, can be very great – as anyone watching or feeling that power eventually being dissipated on a beach will know.

Various technologies for harnessing the power of waves have been developed over the past few decades, of which the 'oscillating water column' (OWC) is perhaps the most widely used. In an OWC, the rise and fall of the waves inside an enclosed

3.3 Nuclear energy

Nuclear energy is based on harnessing the very large quantities of energy that are released when the nuclei of certain atoms, notably uranium-235 and plutonium-239, are induced to split or 'fission'. The complete fission of a kilogram of uranium-235 should produce, in principle, as much energy as the combustion of over 3000 tonnes of coal. In practice, the fission is incomplete and there are other losses, but nevertheless nuclear fuels are more highly concentrated sources of energy than fossi

4.1 Introduction

We have seen in SAQ 18 of Section 3.4 how some sets of points of the complex plane can be described algebraically in terms of operations on C. We now use the modulus function to take this a step further by defining discs in the complex plane. As we shall see, discs are extensively used in arguments involving l

2.1.1 Preparation

Prepare to watch the video in just the same way as you would prepare to study written material. You will need to have a suitable environment in which you should be relatively undisturbed and able to concentrate for the full length of each video extract. You will need to be able to take some notes as you watch – it is easy to forget the key points if you leave note taking until the video is finished, and it will be important to record your immediate reactions to some of the images.

Groups and teamwork
Are you always the quiet one when it comes to group discussion? This free course, Groups and teamwork, will help you improve your working relationships with other people in groups of three or more. The course also deals with project life cycles, project management and the role of the leader. First published on Mon, 10 Dec 2018 as Author(s): Creator not set

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

Learning, thinking and doing
How do we learn? Understanding how is the key to learning more effectively. This free course, Learning, thinking and doing, looks at the three main categories of theories: the acquisitive, constructivist and experiential models of learning. There is no right way to learn but developing an active approach will ensure that you are open to new ideas. Author(s): Creator not set

2.5 Living systems and information flows

Understanding the role of information flows in feedback relationships is often confusing. It is relatively easy to visualise flows of energy and matter (ecosystem food webs, water flowing through a rainforest ecosystem, etc). But how does information ‘flow’ within feedback loops, and how does this affect systems?

The first point to make clear is that information is only meaningful to those systems that can perceive it. In other words, these systems need to have components th

6.3 Summary of Section 6

  • In trying to find solutions to the specific problem of the water-boiler, where the need was for a particular response to a certain temperature change, we have gone into the principles behind the three classes of temperature effect – gradual, accelerating and sudden. This has provided you with mathematical models that are of real use in putting definite numbers to the magnitudes of these effects in any designs that are proposed. The ability to do this is ju

4.4 Summary of Section 4

  • Thermal energy is a random thing, so any group of particles possessing it will have a distribution of kinetic energies.

  • The fraction of particles with energy greater than an amount E1 is proportional to exp(−E1/kT).

  • Thermally activated rates follow Arrhenius's law and are characterised by an activation energy.

  • Diffusion in solids and electrical conduction in ceram

4.2.2 The significance of the average energy

The average thermal energy of the atoms in a solid indicates how much they are 'rattling' or vibrating around their mean positions. Since the atoms are close together, virtually touching, and because atoms are almost incompressible, they cannot get much closer. But they can get further apart. So, since thermal energy is manifested in the vibrations of the atoms, bigger vibrations mean that the atoms must spend more time further apart. On average then, there is a tendency for a solid to expand
