2.1 The development of gender identity

In this section we are going to look at where we come from in terms of childhood experience and the development of gender identities in childhood. Gender identity involves the construction and use of gender categories. Children's gender categories are at first rather simplistic; but, as we shall see, children refine their categories so that they become more reliable and useful for their social lives. Studying the development of gender identity in children reveals that this is a story of a sea

Conclusion

Earthquakes shake the ground surface, can cause buildings to collapse, disrupt transport and services, and can cause fires. They can trigger landslides and tsunami.

Earthquakes occur mainly as a result of plate tectonics, which involves blocks of the Earth moving about the Earth's surface. The blocks of rock move past each other along a fault. Smaller earthquakes, called foreshocks, may precede the main earthquake, and aftershocks may occur after the main earthquake. Earthquakes are mai

2.3 From infected cells to transgenic plants

Unlike the 'natural' infection process, where only the cells at the site of the crown gall are affected by the inserted T-DNA, scientists wanted to introduce new genes into all the cells of the plant. Fortunately, most plant cells are totipotent, which means that any cell from any part of the plant is capable of dividing into cells that can form any or all of the plant's tissues. This means that, using appropriate growth hormones and other tissue culture techniques, a single infected p

1.2 Who am I?

Let us start with an example of an individual and his identity which illustrates the link between the personal and the social. The social scientist Madan Sarup uses the example of his passport, which gives information about his identity in an official sense. Our passports name, describe and place us. A passport describes an individual; it names one person. It also states to which group, in particular which nation, that person belongs:

2.4.1 Phosphorus (P)

Like calcium, phosphorus is important in the structure of bones and teeth. It is vital in the body as part of the molecules ATP and DNA, and is also a component of phospholipids, lipoproteins and many other proteins too. Phosphorus can occur, combined with oxygen, in phosphate ions and in this form it plays an important role in switching on and off metabolic pathways in cells. Phosphorus is widely available in the diet, from both plant and animal sources, such as meat, fish, eggs and dairy pr

1.1 What is the carbon footprint and why is it important?

The carbon footprint is the annual amount of greenhouse gas emissions, mainly carbon dioxide, that result from the activities of an individual or a group of people, especially their use of energy and transport and consumption of goods and services. It's measured as the mass, in kilograms or tonnes per year, either of carbon dioxide (CO2) emissions alone, or of the carbon dioxide equivalent (CO2e) effect of other greenhouse gas emissions.

2.11 Further reading

Grice's writing on the philosophy of language, including the 1957 paper ‘Meaning’, is collected in Grice 1989. Discussion of the issues raised in ‘Meaning’ can be found in Avramides 1997 (the most accessible), Blackburn 1984, Miller 1998, and Taylor 1998. A defence of the Gricean Programme can be found in Schiffer 1972, later retracted in Schiffer 1987. Searle's position is developed at length in Searle 1969.

2.2 A society frightened by crime?

We do not have to look too far to find someone saying that the UK is a society gripped by rising levels of crime, anti-social behaviour and incivility; or that disorder threatens social stability. The criminologist Robert Reiner suggests that ‘in the last 40 years, we have got used to thinking of crime, like the weather and pop music, as something that is always getting worse’ (Reiner, 1996, p. 3). So who is telling this story?
