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.

5.3 How devolution in Scotland differs from devolution in Wales

Devolution for Wales, rejected by the Welsh in a 1979 referendum, was also part of the constitutional reform package of the Labour government. However, in September 1997, the Welsh voted for the establishment of a National Assembly for Wales. The referendum result in favour was far narrower than in Scotland. On a 50.3 per cent turn-out in Wales, only 50.6 per cent voted in favour, indicating a far less entrenched sense of political identity and difference from the rest of the UK on the part o

4.3 How effective are antidepressants in general?

Despite the rapidly expanding use of antidepressants, to date there is very little evidence that they are effective for the treatment of bereavement or in mild to moderate types of depression. Recent meta-analyses (a technique for combining the results of a number of studies) reported by Joanna Moncrieff and Irving Kirsh, a British psychiatrist and psychologist respectively, show that selective serotonin re-uptake inhibitors (SSRIs), such as paroxetine (Seroxat) and fluoxetine (Prozac), have

2.2 Researching ourselves

Psychology aims to provide understandings of us, as humans. At a personal level this closeness to our private concerns draws us in and excites us. However, since psychologists are humans, and hence are researching issues just as relevant to themselves as to their research participants, they can be attracted towards researching certain topics and maybe away from others. This is perhaps more evident for psychological research that is most clearly of social relevance. At a societal level all kin

3.1 Background

In practice, there is almost always some element of risk (in the technical sense of ‘uncertainty’) in any investment return. There is in finance the theoretical concept of a truly risk-free asset, but at the moment it is sufficient just to be aware of the main factors causing risk or uncertainty in practice. These are:

  • maturity

  • liquidity

  • variability of income

  • default or credit risk
