Problems in communication, and a convention concerned with this, would try to address the problem of various cultures trying to communicate effectively with each other. Conventions and congresses of this nature take place all around the world.
They serve an essential role in helping people who live in different cultures,and who speak different languages, to cope with the problems thereof.
With the globalization of business in this century, has come the problem of people who would never have normally communicated with each other, being forced to communicate with each other, and what is more, to understand and co-operate with each other.
This is more complex than it sounds. The language they normally communicate in to do this business, is English, which is a difficult language to grasp well, and communicate effectively in, if it is not your first language.
What compounds this further, is talking long distance on a telephone under pressure, and also conference calls, which involve people of many different cultures, all taking to each other by telephone, at once.
