16.6 Pricing and stock control

A supermarket has a large database of information about its goods, such as the name, price, size and quantity held in stock.

If the price of a particular item changes, the relevant data in the supermarket's database can be easily updated. When the bar code for an item is scanned, the checkout computer searches the database for the item and retrieves the new price. Because the checkout computers are networked, they all use the same data on the database server, so it is not necessary to c

"All the Colored Women Like This Work": Black Workers During World War I
Wartime production demanded the mobilization of thousands of workers to make steel and rubber, to work in petrochemical industries, and to build ships. As a result, African Americans made striking gains in employment even while also facing continuing discrimination. Black women, for example, got jobs working on the railroads for the first time during the world war. Black women found jobs as laborers, cleaning cars, wiping engines, tending railroad beds. Helen Ross was one of them, working for th

Coping with Depression
“You just want to step out of it, to step out of the whole race, the whole business. The monstrosity of life overwhelms you.” Following a nervous breakdown in 1995, actor and journalist Stephen Fry discovered he was suffering from bi-polar disorder – commonly known as manic depression. Symptoms of fear and sadness (often classed as ‘anxiety’ and ‘depression’ if they are diagnosed) are the most common ‘mental disorders’ in Britain that people seek counselling for. This collectio

6.3 Setting things apart

The tendency within religious behaviour to set things apart from the everyday does not just apply to time and place but also to ideas of authority (leaders and texts), to beliefs more generally, to institutions and to aspects of behaviour as, for example, in dress and diet. In fact, the concept of ‘religion/religious’ is often set over and against the concept of the ‘temporal’ and the ‘secular’, which both suggest an outlook that is concerned solely with this world, the here and n

Stoney Knows How
Stoney Knows How is an extended interview with 'Stoney' St. Clair, an ebullient little man with the gift of gab of a circus tout and a fund of bizarre stories about tattooing and other matters. One of these is the tale of a Florida snake handler and tattoo artist who was squeezed to death by his own python. His widow made a fortune touring the South with the guilty snake. "After all," says Stoney, "how often do you get a chance to see a snake that's squeezed a man to death?" Not often, nor does

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.

2.2 1 Social Darwinism and eugenics

Nineteenth century reformers combined their new medical diagnoses with a concern to tackle what they saw as the social causes of cruelty and incapacity. Two theories dominated: social Darwinism and eugenics.

Social Darwinism drew on Darwin's ideas of natural selection and emphasised the contribution of the fittest and most superior individuals to the survival of the human species. The social Darwinists, who included some of the most prominent thinkers of their time, believed that social
