Advertising

Advertising as referred to in most economic books is part of the marketing mix. Therefore advertising usually is closely associated with the aim of selling products and services. Still, developments like "branding" show a tendency towards the marketing of not only products and services, but of ideas and values. While advertising activities are also pursued by political parties, politicians and governmental as well as non-governmental organizations, most of the money flowing into the advertising industry comes from corporations. Although these clients come from such diverse fields, their intentions hardly differ. Attempting to influence the public, their main goal is to sell: Products, services, ideas, values and (political) ideology.

Gait recognition

The fact that an individual's identity is expressed not only by the way he/she looks or sounds, but also by the manner of walking is a relatively new discovery of in biometrics.

Unlike the more fully developed biometric technologies whose scrutiny is directed at stationary parts of the body, gait recognition has the added difficulty of having to sample and identify movement. Scientists at the University of Southampton, UK (http://www.isis.ecs.soton.ac.uk/research/gait/) have developed a model which likens the movement of legs to those of a pendulum and uses hip inclination as a variable.

Another model considers the shape and length of legs as well as the velocity of joint movements. The objective is to combine both models into one, which would make gait recognition a fully applicable biometric technology.

Given that gait recognition is applied to "moving preambulatory subjects" it is a particularly interesting technology for surveillance. People can no longer hide their identity by covering themselves or moving. Female shop lifters who pretend pregnancy will be detected because they walk differently than those who are really pregnant. Potential wrongdoers might resort walking techniques as developed in Monty Pythons legendary "Ministry of Silly Walks" (http://www.stone-dead.asn.au/sketches/sillwalk.htm)

Palm recognition

In palm recognition a 3-dimensional image of the hand is collected and compared to the stored sample. Palm recognition devices are cumbersome artefacts (unlike fingerprint and iris recognition devices) but can absorb perform a great amount of identification acts in a short time. They are therefore preferably installed in situations where a large number of people is identified, as in airports.

Iris recognition

Iris recognition relies upon the fact that every individuals retina has a unique structure. The iris landscape is composed of a corona, crypts, filaments, freckles, pits radial furrows and striatations. Iris scanning is considered a particularly accurate identification technology because the characteristics of the iris do not change during a persons lifetime, and because there are several hundred variables in an iris which can be measured. In addition, iris scanning is fast: it does not take longer than one or two seconds.

These are characteristics which have made iris scanning an attractive technology for high-security applications such as prison surveillance. Iris technology is also used for online identification where it can substitute identification by password. As in other biometric technologies, the use of iris scanning for the protection of privacy is a two-edged sword. The prevention of identity theft applies horizontally but not vertically, i.e. in so far as the data retrieval that accompanies identification and the data body which is created in the process has nothing to do with identity theft.

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 Ku Klux Klan and mailboxes like the Aryan Nations Liberty Net. In the meantime those mailboxes can be found in the internet. In 1997 about 600 extreme right websites were in the net, the number is growing, most of them coming from the USA. The shocking element is not the number of racist pages, because still it is a very small number compared to the variety of millions of pages one can find in this media, it is the evidence of intentional disinformation, the language and the hatred that makes it dangerous.
A complete network of anti-racist organizations, including a high number of websites are fighting against racism. For example:

Automation

Automation is concerned with the application of machines to tasks once performed by humans or, increasingly, to tasks that would otherwise be impossible. Although the term mechanization is often used to refer to the simple replacement of human labor by machines, automation generally implies the integration of machines into a self-governing system. Automation has revolutionized those areas in which it has been introduced, and there is scarcely an aspect of modern life that has been unaffected by it. Nearly all industrial installations of automation, and in particular robotics, involve a replacement of human labor by an automated system. Therefore, one of the direct effects of automation in factory operations is the dislocation of human labor from the workplace. The long-term effects of automation on employment and unemployment rates are debatable. Most studies in this area have been controversial and inconclusive. As of the early 1990s, there were fewer than 100,000 robots installed in American factories, compared with a total work force of more than 100 million persons, about 20 million of whom work in factories.

Newsgroups

Newsgroups are on-line discussion groups on the Usenet. Over 20,000 newsgroups exist, organized by subject into hierarchies. Each subject hierarchy is further broken down into subcategories. Covering an incredible wide area of interests and used intensively every day, they are an important part of the Internet.
