This chapter analyses the change (or continuity) of MENA regimes in a post-Arab Spring context, focusing on governments and power relationships. This chapter firstly analyses the place governments occupy in their respective political systems; how they are perceived by their populations; and the extent to which are they capable of managing violence and imposing their authority across the whole of their national territory. Governments are responsible for the policies carried out in their countries. Thus, many of the social protests - predominantly focused on the high levels of corruption - were directed against governments. However, while governments are perceived to be the institutions responsible for meeting citizens’ welfare needs, there are other non-elected institutions (formal or informal) with significant decision-making powers that are non-accountable, such as the presidents of the republic, the monarchs, and other national (the armed forces in the case of Egypt; armed groups in the cases of Libya, Syria and Yemen) or international actors (such as Saudi Arabia and Iran). On the other hand, this chapter studies changes in the power structure. The author finds evidence of greater power concentration, with the exception of the new democratic regime of Tunisia.

In South Africa the modern outlook towards time may be said to have started in 1948. Both the two major observatories, The Royal Observatory in Cape Town and the Union Observatory (now known as the Republic Observatory) in Johannesburg had, of course, been involved in the astronomical determination of time almost from their inception, and the Johannesburg Observatory has been responsible for the official time of South Africa since 1908. However the pendulum clocks then in use could not be relied on to provide an accuracy better than about 1/10 second, which was of the same order as that of the astronomical observations. It is doubtful if much use was made of even this limited accuracy outside the two observatories, and although there may – occasionally have been a demand for more accurate time, it was certainly not voiced.
