Diphthongs

Described as vowel glides, since in their production the tongue begins in one place and moves to another. This movement of the tongue, however smooth, results in a change of vowel quality, which is why diphthongs are sometimes looked upon as 'combinations of 2 vowels'.

Diphthongs are usually classified according to whether they are:

• Falling or rising
• Wide or narrow
• Front or back
• Closing or centering

The diphthongs of RP are all stressed on the first element, described as falling. Those stressed on the finishing point (rising), can also be wide or narrow, according to the movement of the tongue from the first to the second target. Those in which the position of the tongue body changes quite noticeably are described as 'wide diphthongs'....

The Cold War: An Overview

The Rise of Two Power Blocs

The Second World War dramatically reshaped global politics. In 1945, the Allied forces, led by the US, Soviet Union, Britain, and France, defeated the Axis powers. This victory led to the emergence of two dominant powers: the US and the USSR. These powers gradually formed two opposing blocs: the Western camp, led by the US, and the Eastern camp, led by the USSR. For the first time, global politics became organized along ideological lines, with the US representing liberal democracy and the USSR championing socialism and communism.

The Cold War differed from previous wars because it lacked direct military conflict between the US and the USSR. Instead, it was an ideological...

Introducing Networks

A network is created when more than one device is connected together. A network can be a small collection of computers connected within a building (e.g. a school, business, or home) or it can be a wide collection of computers connected around the world.

Advantages

• Communication – it is easy (and often free) to communicate using email, text messages, voice calls, and video calls.
• Roaming – if information is stored on a network, it means users are not fixed to one place. They can use computers anywhere in the world to access their information.
• Sharing information – it is easy to share files and information over a network. Music and video files, for instance, can be stored on one device and shared across many computers, so

The Second Decade: Noucentisme

During the second decade, the theater exhibited Noucentista characteristics: rationalism, anti-romanticism, a preference for classical and intellectualized expression of emotions, a defense of pure art, and works directed towards a knowledgeable, sophisticated audience. There was extreme concern for the design, structure, and language of the work.

Leading Authors of the Second Decade

• Ramon del Valle-Inclán: In his primitive stage, he wrote works like Romance of Wolves and Eagle Crest. Their common features are violence, cruelty, brutality, destruction, passion, myths, and superstitions. There are plenty of marginal and strange beings. During his time of artificial distancing,
