Global Data Flows In the space of flows constituted by today's global data networks the space of places is transcended. Visualizations of these global data flows show arches bridging seas and continents, thereby linking the world's centres of research and development, economics and politics. In the global "Network Society" (Manuel Castells) the traditional centres of power and domination are not discarded, in the opposite, they are strengthened and reinforced by the use of information and communication technologies. Political, economical and symbolical power becomes increasingly linked to the use of modern information and communication technologies. The most sensitive and advanced centres of information and communication technologies are the stock markets. Excluded from the network constituted by modern information and communication technologies, large parts of Africa, Asia and South America, but also the poor of industrialized countries, are ranking increasingly marginal to the world economy. Cities are centres of communications, trade and power. The higher the percentage of urban population, the more it is likely that the telecommunications infrastructure is generally good to excellent. This goes hand in hand with lower telecommunications costs. Those parts of the world with the poorest infrastructure are also the world's poorhouse. In Bangladesh for most parts of the population a personal computer is as expensive as a limousine in European one-month's salary in Europe, they have to pay eight annual salaries. Therefore telecommunications infrastructure is concentrated on the highly industrialized world: Most telephone mainlines, mobile telephones, computers, Internet accounts and Internet hosts (computers connected to the global data networks) can be found here. The same applies to media: the daily circulation of newspapers and the use of TV sets and radios. - Telecommunication and media services affordable to most parts of the population are mostly restricted to industrialized countries. This situation will not change in the foreseeable future: Most expenditure for telecommunications infrastructure will be restricted to the richest countries in the world. In 1998, the world's richest countries consumed 75% of all cables and wires. |

Biometric technologies In what follows there is a brief description of the principal biometric technologies, whose respective proponents - producers, research laboratories, think tanks - mostly tend to claim superiority over the others. A frequently used definition of "biometric" is that of a "unique, measurable characteristic or trait of a human being for automatically recognizing or verifying identity" ( All biometric technologies are made up of the same basic processes: 1. A sample of a biometric is first collected, then transformed into digital information and stored as the "biometric template" of the person in question. 2. At every new identification, a second sample is collected and its identity with the first one is examined. 3. If the two samples are identical, the persons identity is confirmed, i.e. the system knows who the person is. This means that access to the facility or resource can be granted or denied. It also means that information about the persons behaviour and movements has been collected. The system now knows who passed a certain identification point at which time, at what distance from the previous time, and it can combine these data with others, thereby appropriating an individual's data body. |

Face recognition In order to be able to recognize a person, one commonly looks at this persons face, for it is there where the visual features which distinguish one person from another are concentrated. Eyes in particular seem to tell a story not only about who somebody is, but also about how that persons feel, where his / her attention is directed, etc. People who do not want to show who they are or what is going on inside of them must mask themselves. Consequently, face recognition is a kind of electronic unmasking. "Real" face-to-face communication is a two-way process. Looking at somebody's face means exposing ones own face and allowing the other to look at oneself. It is a mutual process which is only suspended in extraordinary and voyeuristic situations. Looking at somebody without being looked at places the person who is visually exposed in a vulnerable position vis-à-vis the watcher. In face recognition this extraordinary situation is normal. Looking at the machine, you only see yourself looking at the machine. Face biometrics are extracted anonymously and painlessly by a mask without a face. Therefore the resistance against the mass appropriation of biometrical data through surveillance cameras is confronted with particular difficulties. The surveillance structure is largely invisible, it is not evident what the function of a particular camera is, nor whether it is connected to a face recognition system. In a protest action against the face recognition specialist According to |

Virtual cartels; mergers In parallel to the deregulation of markets, there has been a trend towards large-scale mergers which ridicules dreams of increased competition. Recent mega-mergers and acquisitions include SBC Communications - Ameritech, $ 72,3 bn Bell Atlantic - GTE, $ 71,3 AT&T - Media One, $ 63,1 AOL - Time Warner, $ 165 bn MCI Worldcom - Spring, $ 129 bn The total value of all major mergers since the beginnings of the 1990s has been 20 trillion Dollars, 2,5 times the size of the USA's GIP. The AOL- Time Warner reflects a trend which can be observed everywhere: the convergence of the ICT and the content industries. This represents the ultimate advance in complete market domination, and a alarming threat to independent content. "Is TIME going to write something negative about AOL? Will AOL be able to offer anything other than CNN sources? Is the Net becoming as silly and unbearable as television?" (Detlev Borchers, journalist) |

More and more, faster and faster, but... Since the invention of appropriate means and technologies, communication no longer requires face-to-face meetings. From writing and reading to using computers, expanding and exhausting one's possibilities to communicate relies more and more on the application of skills we have to learn. With the increasing importance of communication technologies, learning to apply them properly becomes a kind of rite of passage. A Small World From the very beginning - the first Sumerian pictographs on clay tablets - to today's state of the art technologies - broadband communication via Since the invention of the electrical telegraph, but especially with today's growing digital communication networks, every location on earth seems to be close, however distant it may be, and also time no longer remains a significant dimension. Threatened Cultural Memory More and more information is transmitted and produced faster and faster, but the shelf life of information becomes more and more fragile. For more than 4500 years Sumerian pictographs written on clay tablets remained intact, but newspapers and books, printed some decades ago, crumble into pieces; film reels, video tapes and cassettes corrode. Digitalization of information is not a cure; on the contrary it even intensifies the danger of destroying cultural heritage. Data increasingly requires specific software and hardware, but to regularly convert all available digitized information is an unexecutable task. Compared to the longevity of pictographs on clay tablets, digitized information is produced for instant one-time use. The increasing production and processing of information causes a problem hitherto unknown: the loss of our cultural memory.

What is the Internet? Each definition of the Internet is a simplified statement and runs the risk of being outdated within a short time. What is usually referred to as the Internet is a network of thousands of computer networks (so called autonomous systems) run by governmental authorities, companies, and universities, etc. Generally speaking, every time a user connects to a computer networks, a new Internet is created. Technically speaking, the Internet is a What constitutes the Internet is constantly changing. Certainly the state of the future Net will be different to the present one. Some years ago the Internet could still be described as a network of computer networks using a common communication protocol, the so-called Also, the Internet is not solely constituted by computers connected to other computers, because there are also point-of-sale terminals, cameras, robots, telescopes, cellular phones, TV sets and and an assortment of other hardware components that are connected to the Internet. At the core of the Internet are so-called Since these networks are often privately owned, any description of the Internet as a public network is not an accurate. It is easier to say what the Internet is not than to say what it is. On 24 October, 1995 the U.S. What is generally and in a simplyfiying manner called the Internet, may be better referred to as the Matrix, a term introduced by science fiction writer Strictly speaking, the Matrix is not a medium; it is a platform for resources: for media and services. The Matrix is mainly a very powerful means for making information easily accessible worldwide, for sending and receiving messages, videos, texts and audio files, for transferring funds and trading securities, for sharing resources, for collecting weather condition data, for For a comprehensive view of uses of the Matrix, especially the World Wide Web, see " |

Racism on the Internet The internet can be regarded as a mirror of the variety of interests, attitudes and needs of human kind. Propaganda and disinformation in that way have to be part of it, whether they struggle for something good or evil. But the classifications do no longer function. During the last years the internet opened up a new source for racism as it can be difficult to find the person who gave a certain message into the net. The anarchy of the internet provides racists with a lot of possibilities to reach people which they do not possess in other media, for legal and other reasons. In the 1980s racist groups used mailboxes to communicate on an international level; the first ones to do so were supposedly the A complete network of anti-racist organizations, including a high number of websites are fighting against racism.

Theoedore Roosevelt With the assassination of President McKinley, Theodore Roosevelt (1858-1919), not quite 43, became the youngest President in the Nation's history. Roosevelt's youth differed sharply from that of the log cabin Presidents. He was born in New York City in 1858 into a wealthy family. Roosevelt steered the United States more actively into world politics. He liked to quote a favorite proverb, "Speak softly and carry a big stick. . . . " He won the Nobel Peace Prize for mediating the Russo-Japanese War. for more information see the official website: |

Expert system Expert systems are advanced computer programs that mimic the knowledge and reasoning capabilities of an expert in a particular discipline. Their creators strive to clone the expertise of one or several human specialists to develop a tool that can be used by the layman to solve difficult or ambiguous problems. Expert systems differ from conventional computer programs as they combine facts with rules that state relations between the facts to achieve a crude form of reasoning analogous to |

Sergei Eisenstein Though Sergei Eisenstein (1898-1948) made only seven films in his entire career, he was the USSR's most important movie-conductor in the 1920s and 1930s. His typical style, putting mountains of metaphors and symbols into his films, is called the "intellectual montage" and was not always understood or even liked by the audience. Still, he succeeded in mixing ideological and abstract ideas with real stories. His most famous work was The Battleship Potemkin (1923). |
