5.2 Frequency code

Although the evidence for the place theory of frequency coding is compelling, there is some question as to whether the tuning curves obtained from neurons in the auditory nerve provide a mechanism for frequency discrimination that is fine enough to account for behavioural data. People can detect remarkably small differences in frequency – in some cases as small as 3 Hz (for a 1000 Hz signal at moderate intensity). What accounts for this ability? As early as 1930, the American experimental p

4.6.2 Material costs in manufacturing

For high added-value products like boats and cars, material costs form a relatively small proportion of total costs. For directly manufactured products, however, which are sold without much assembly or finishing, material costs do form a relatively large proportion of the total production cost. This applies particularly to polymeric containers for foods and drinks but not, for example, to containers for more sophisticated products like electronic or electrical goods. What is much more importa

Britain was the first country to industrialise, and it acquired the largest empire ever during this same period. But its sphere of economic influence extended far beyond the boundaries of the formal British Empire. This unit focuses on the economics of empire, using a case study of one town, Dundee in eastern Scotland, to explore this huge topic.

4.6 Agency explanations: rational choice theory

The work of the Chicago School, despite the potential pitfalls of participant observation, does demonstrate that if you want to know why people commit crimes it makes sense to ask them. In his memoir of a criminal career in the early twentieth century entitled Jail Journey, Jim Phelan wrote:

The robber is a tradesman who, from economics or other motivation, chooses a trade with greater rewards and dangers th

1 1 Who are Europeans?

When I went to Loughborough for the first time I was pleasantly surprised as a social scientist to see that the town was twinned with Épinal, the French town where the founder of modern sociology, Émile Durkheim, was born. In fact, as you enter any major English town you are likely to see sooner or later a plaque indicating that the town is twinned with another European town. But what is the meaning of this practice?

This course begins with some explanations of culture and discussion of how to distinguish between national and organisational culture. Reading what some well-known writers on organisational and national culture have to say will help you recognise some of the main dimensions of culture and reinforces that all of us, including organisations, construct different views of the world as a result of cultural influences. Thus culture plays a key role in the ways in which organisations perceive the en
