Some recent surveys have suggested that Chinese managers believe that traveling and meetings are the least important aspects of their jobs; they would rather spend more time doing deskwork, assessing and evaluating information and making decisions. It is interesting that only 31 percent of the sample believed that scheduled meetings were an important activity and only 4 percent believed that unscheduled meetings were important.

Satellites have enabled immediate reporting worldwide.A reporter can send the news to a network like CBS News and within seconds it can be all over the world.They send electronic reports that go straight into the newspaper or onto the TV screen.Reporters can now also transmit images through their mobile phones.Consequently, live, “on-the-spot” reporting has become the norm and TV viewers can get a much better idea of what a natural disaster, a conflict or an interesting scientific discovery is like.
In recent years, several changes have occurred in the ownership of news media.Networks owned by large companies and governments have become bigger and very powerful.These networks – such as BBC News 24–are hungry for news and have huge audiences.However, there can only be a limited number of such networks and their ownership is a big issue.
Some companies not only own TV and radio networks but newspaper groups as well.Who decides what news to publish and what sort of “spin” to put on it？ Is it always objective？ There are now “spin doctors” who manipulate the news,emphasising certain parts and not others – and as a result, much of it is not neutral.Therefore, the question of control of the media matters very much.In some cases, the media companies are more powerful than governments.They can even influence elections.So the question is – should they be controlled and if so, by whom？

Prior to the UML, there was no clearleading(66)Ianguage. Users had to choose from among many similar modeling languages with minor differences in overall(67)power. Most of the modeling languages shared a set of commonly accepted concepts that are expressed slightly differently in various languages. This lack of(68)discouraged new users from entering the OO market and from doing OO modeling, without greatly expanding the power of modeling. Users longed for the industry to adopt one, or a very few, broadly supported modeling languages suitable for(69)usage.
Some Vendors were discouraged from entering the OO modeling area because of the need to support many similar, but slightly different, modeling languages. In particular, the supply of add-on tools has been depressed because small vendors cannot afford to support many different formats from many differem(70)modeling tools. It is important to the entire OO industry to encourage broadly based tools and vendors, as well as niche products that cater to the needs of specialized groups.
