 In these lectures on human and organizational factors, we are talking about models of risk communication and we will speak more precisely of one particular example of a communication model applied to a given risk. We will give an example of a model of risk communication about the risk related to mobile phones and especially from radiations from base station transmitters for mobile phones. A communication campaign using the Lasswell model, the emitter receiver model, was initiated about mobile phones related risk. Mobile technology, generally speaking, uses non-ionizing radiation from base station transmitters for mobile phones that can trigger some risks for human health. For example, it intends to use gnosis, insomnia, headaches or cancer and leukemia. Mobilization against these risks have spread since the year 2000, possibly earlier, not only in Italy but also in many other countries all over Europe, although this particular example will relate to Italy. In this country, a risk communication campaign has been triggered by the Ministry of Telecommunication to inform the population on the risks and possibly reduce social conflict which was related to this particular risk. The risk communication campaign we are talking about has some particular features. Number one, the Italian Ministry of Telecommunication performed a one-way unilateral communication campaign on risk based on the emitter receiver model that we have seen previously. Feature number two, this campaign was performed not by experts in communication but by technicians and scientists. Number three, the risk communication campaign used a one-way model of communication and didn't include the citizens on a participatory process about the given risk. The risk communication campaign was performed through the blue bus, which is a bus that traveled in the country, in Italy, in 18 of the 20 regions of Italy, providing information about electromagnetic fields, which means that scientists and technicians on the Ministry of Telecommunication provided general population information about the risk related to base station transmitters for mobile phones. In the picture here, you can see the bus that has been used to perform this campaign that traveled around Italy for almost two years. This communication campaign covered 25,000 km in Italy, visiting 18 regions with 137 stops all along the path and in a time of approximately two years. The problem is that with this particular risk communication model, which was a citizens come and ask campaign one-way process, there was no public debate that has been triggered, which means that citizens have not been involved on a more active basis. And probably more importantly, this did not lead to reduce the social conflict, which was one of the main purposes of the risk communication campaign. In other words, the application of last year's model, emitter receiver model of communication to this particular kind of risk avoiding a more inclusive participatory process did not lessen the social conflict. We have seen one example of the model of communication applied to a particular risk. In the next slides, in the next presentation, we will see some of the possible goals of risk communication.
