1.3 Stages of development

As a result of the consultation and decision-making process, it was decided, as a primary objective, to undertake a systematic survey of the site in order to uncover and understand the industrial archaeology of Aberdulais Falls. This involved removing tons of rubbish, infill and vegetation, and examining in detail the archaeological remains discovered.

During this process, no evidence from the sixteenth-century copper smelting works was uncovered, and it is assumed that this lies beneat

2.2 Insider/outsider perspectives

Social historians have long argued that we must study history ‘from the underside’, if we want to thoroughly understand a society. In other words, it is not sufficient to have a top-down knowledge of a society's institutions and politics. We need also to examine how ordinary, ‘unimportant’ people operate within a culture: what influences them and what they can (and cannot) influence; how they see their role in society and how others see it. The outsider view is the view from

1.3 Representation

Representation is a complex idea, or set of ideas, but it is extremely important in relation to studying religion. Representing religion might mean being an official delegate of a religion, or it might mean trying to explain a religion to someone unfamiliar with it. Representation in the religious context might mean the use of an image to portray a divine figure or religious ideas, or it could refer to how a religion is characterized by either insiders or outsiders. Therefore, the sorts of qu

3.3 Outputs

The principal outputs of a doctor's surgery are cured patients; the outputs of a nuclear reprocessing plant include reprocessed fuel and nuclear waste. Many transformation processes produce both goods and services. For example, a restaurant provides a service, but also produces goods such as food and drinks.

Transformation processes may result in some undesirable outputs (such as nuclear waste in the example above) as well as the goods and services they are designed to deliver. An impor

3.2 Technology and costs in the short run

Advertising leaflets are dropping through letter boxes around the UK, as we are writing this chapter, from cable suppliers trying to attract new customers for their services. They promise to provide a telephone line, a bundle of television channels, an Internet connection, home shopping and movies-on-demand, all at a ‘bargain price’. These leaflets raise some interesting questions. How does expanding output of cable services by selling to new customers make it possible to offer them

1 Technological change, demand and costs

The new economy

Over the past 40 years global computing power has increased a billionfold. Number-crunching tasks that once took a week can now be done in seconds. Today a Ford Taurus car contains more computing power than the multimillion-dollar mainframe computers used in the Apollo space programme. Cheaper processing allows computers to be used for more and more purposes. In 1985, it cost Ford
