6.1 ‘Non-citizenship’ to ‘social-citizenship’ and worker rights

We respect our masters, and are willing to work for our support, and that of our parents, but we want time for more rest, a little play, and to learn to read and write. We do not think it right that we should know nothing but work and suffering, from Monday morning to Saturday night, to make others rich. Do, good gentlemen, inquire carefully into our concern.

Introducing Health Sciences: The Pain Clinic
We are all likely to experience pain at some stage in our lives. But, how do you deal with constant, chronic pain? Learning to manage severe pain on a daily basis takes a phenomenal amount of mental and physical strength. The 7 video tracks in this album introduce patients and doctors at the Royal Free Hospital's Pain Clinic and the Real Health Institute in London. They explore the causes of pain, the changes it brings to the lives of sufferers and the ways in which drugs, surgery, physiotherapy

6.5 The neurotransmitters histamine and serotonin: a role for chemical signalling between neurons of

As in all other regions of the brain, the integration of physiological change in the hypothalamus, conducted by the dialogue between many thousands of nerve cells, is the result of transmissions across chemical synapses. The functions of the hypothalamus are therefore dependent upon neurotransmission by a number of different chemical mediators and are critically dependent on the balance between their respective activities. Monoamine neurotransmitters (histamine and serotonin) operate in subgr

2.8 Attenuation and distortion

As a signal travels from one device to another it has two problems to overcome. The first is that it gets weaker the further it travels, because some of its energy is absorbed by the transmission medium. This effect is known as attenuation. The extent of attenuation depends on the distance it has to travel and on the type of medium it is travelling through. An amplifier can be used to boost the signal power at the transmitter and receiver, and if necessary at various points in the tran

  • temperatures recorded at intervals during a day

  • weight of each bunch of grapes sold at a supermarket yesterday.

Time, temperature and weight are all examples of numerical data, but there is not a restricted set of values that they can take. Whereas you can have 2 or 3 children in a family but not 2.5, with tempe

10.5 Desire to help others

This is a less common motivation but it shows not everyone is driven by money.

In 1991 the inventor Trevor Baylis saw a BBC documentary about the spread of HIV/AIDS in Africa. What was needed was a way of broadcasting the safe-sex message to people in areas without electricity and where batteries for a radio could cost a month's wages. Solar power wouldn't necessarily help as most people who could get to a radio listened in the evening after work. While absorbing this information he ima

2.2.3 Ecological economics

Ecological economics, which formally came to prominence in the mid-1980s, represents a departure from reliance on the use of mainstream economic modelling. Instead, it branches out to actively engage with and incorporate the ethical, social and behavioural dimensions of environmental issues. In short, ecological economics attempts to provide an interdisciplinary approach to environmental issues, whereas environmental economics maintains the primacy of economic modelling.

5.10 Contextualising any particular systems approach

The capacity to put any systems approach into context is based on the ability of a practitioner to appreciate their own traditions of understanding and to make connections with the history of particular systems methods or methodologies, or to formulate their own. Above all, there is a need to learn from using them and to achieve outcomes that are agreed by those involved as worthwhile. This is a level of systems practice to which you can aspire.
