Parties, Campaigns and Representation: The Political Impact of Blogs and Social Media
Are social media tools likely to prove effective in engaging any voters except those who are already interested in politics? Is their apparent 'democratisation' of traditional party structures to be believed? The outcome of political careers and even campaigns is increasingly dependent on the successful mastery of new communication tools including social media. Many MPs and members of Congress are embracing the use of social networking tools to keep in touch with their constituents, whilst Face

5.4 Hutton's geology: The Jedburgh unconformity

One concrete example from the Theory of the Earth will perhaps indicate the way in which Hutton could read features of the landscape as evidence of the action of forces acting over immeasurably long periods. He had been geologising in the valley of Jed Water, near Jedburgh, in the Borders area between England and Scotland. From his observations in the neighbouring Teviot valley, he expected the Jed to be running over a bed of horizontally laid, soft strata which were sometimes exposed

6.4 Summary

Amplitude refers to the size of a sine wave. It can be defined in various ways, but a standard definition is that it is the maximum value of a wave's departure from its average value. (The average value of a sine wave lies midway between its peaks and troughs.) The size of a sine wave is sometimes also expressed as a peak-to-peak amplitude, which is the vertical distance from peak to trough.

Root-mean-square (r.m.s.) amplitude is a way of specifying the size of a sine wave so that compa

5.5 Emergency planning as an organisational management function

If emergency services' EPOs plan to respond to other people's emergencies, people managing a business activity with major incident potential have a different perspective. They have to respond to emergencies within their own organisation. In effect, if an incident occurs, the organisation is itself in a crisis, with functionality impaired. All of this comes into the corporate governance area and the implications of internal control. This requires companies to ensure that they have a sound syst

6.2 A systematic approach to risk assessment

In Section 4 of this course you learned of the immense value of information to modern organisations. However, without a storage medium of some kind – paper, a hard disk, a white board, a human memory – information is entirely ephemeral. Once recorded in a medium, though, information endures and can be manipulated; but it also becomes subject to the vulnerabilities of that medium and of the systems that access that medium. And once there are vulnerabilities, there are threats to the securi

1.1 Declining fertility

In Britain, fertility decline occurred roughly between 1860 and 1930 – a span which includes the middle and end of the Victorian period (1860–1900), the Edwardian period (1900–1914), the First World War (1914–1918) and the 1920s. We will focus on the British experience, although a similar phenomenon has been noted in many other parts of the world. Fertility decline, also known as the demographic transition, is characterised by a shift from a ‘traditional’ norm of large families an
