3.7 Selecting the sex of a child

Once a pregnancy has been established, many couples are anxious to know the sex of their unborn baby. The reasons for this are many, ranging from the prosaic (will the baby be able to use its brother's or sister's old clothes) to the deeply religious (as described for Hindus in Section 2). In many communities there is so much social pressure on mothers to produce the ‘right’ sex (usually male) that infanticide of the ‘wrong’ sex is widely practised. Because this is illegal in most soc

2.3.1 The risk society

The shift from an anthropocentric concern around issues of human poverty in industrial society towards a more ecocentric concern around environmental issues in the ‘risk society’ has been expressed by the German sociologist Ulrich Beck. His 1992 book Risk Society: Towards a New Modernity suggests a shift from the safety state of industrialised society, where conflicts were manifest in struggles amongst socio-economic groups, to a society where conflicts arise from issues of uncerta

3.1 The helical structure of DNA

Having outlined the general principles of nucleic acid structures, we will now focus on how these principles influence the formation of specific structures found in DNA.

The helical structure of DNA arises because of the specific interactions between bases and the non-specific hydrophobic effects described earlier. Its structure is also determined through its active synthesis; that is, duplex DNA is synthesised by specialist polymerases upon a template strand. Within the helix, the two

William Peffer's Scrapbook
In the late 19th century, American tax laws favored Northeastern industrialists, who amassed enormous fortunes, while farmers in rural America found it harder and harder to make a living. The Farmer's Alliance, combined with other labor movements, formed The People's Party and took control of the Kansas House of Representatives in 1890. Kansas newspaper editor, William Peffer, represented the Populists in the U. S. Senate from 1891 to 1897. This podcast is drawn from his editorials, which champi

1.5.4 Networks

The way Katrina's story is presented leaves out others who may be involved with the family. This is because the story was part of a campaign by Community Care magazine to highlight the plight of young carers. It made sense to emphasise Katrina's role and omit information which might detract from the impact of a single-issue campaign.

The discovery of young carers is an interesting example of what happens when the official spotlight is turned on a particular group in society. Ther
