The sense and the need for the closure of educational institutions during the Corona pandemic, be passion, be discussed jointly. Not only the School but also the University buildings are deserted since mid-March, almost all over the world. At universities, no emergency care takes place, only scientists sitting under the restrictions in the offices. The teaching takes place online, over video conferencing and learning platforms.
discomfort and critique of the virtual University ignite less to the consequences for the students, for which the absence is likely to be their part-time jobs, for example, in the gastronomy, dramatic. Rather, within and outside of the University, the end of the presence of the University fears that in some of the comment even as a secret Plan of the education bureaucracy perhorres ed. Given the mixed experiences with the Online teaching, which is perceived despite the successful conversion mainly as a nuisance, is likely to be a future "Zoom in"on the duty of universities is about as likely as a Sars-CoV-2-compulsory vaccination.
For a temporary restriction of the presence doctrine is, perhaps, particularly contagious, however, there are good reasons for that. These are the importance of universities and other organizations with many members – for the Diffusion of infectious diseases. Even more than in manufacturing, perhaps even more so than in schools in the University system resulting contacts are suitable for a quick and to make far-reaching spread of infection is likely. This conclusion suggests a new study by the Cornell University, in the structure of social networks at this University was examined.
The contact structure of universities depends on the participation in Lectures and seminars, but also from common meals in the refectory, parties in the dorms and random encounters. Only a part of which is included in the study, namely, the contact opportunities of the more than 20,000 students on the basis of their Course assignments. In a week a Student participates with an average of 500 different students in classroom events. Of course, any common course assignment does not mean a risk of contagion: In a large room the distance to some of the other participants can be too large. And not all are present.
students bimodal networks
However, form the structure of the student, the contact network is, in principle, a Paradise for viruses and bacteria. This becomes clear when you look at it as a "bimodal network," which consists of two types of nodes: events and students. Relationships in this network through joint participation in events. In particular, large Lectures are run by "Hubs" in the network, using the numerous links. In sum, this means that the average distance between two peers in the network is very small: it is 2.5 and thus, everyone is far from each other in only an average of 1.5 courses. This means that if any two students do not attend the same course, there is a high probability that they share seminars and Lectures, with a third student.
the student's network, consequently, a "small-world"network, in which a highly contagious Virus of any node from any other node on the short path you can reach: Over 90 percent of the students are within three steps of each other, and in the area of the Undergraduates who attend many great events, this score even close to 100 percent.Updated Date: 12 June 2020, 16:21
