Electronic communication and data-processing are by no means a new phenomenon in general practice. The next logical step might be to include telemedicine, i.e. images, sound, video, and other kinds of medical information in the communication process. The potential for applying telemedicine in the adjoining areas between the general practice and the hospitals and patients is reviewed. We assume that an increase in the use of electronic communication and telemedicine will strengthen the central role of general practice. A representative sample of international literature is reviewed. The findings are that patients have no substantial misgivings against the use of telemedicine, but scientific documentation of the influence on the patient-doctor relationship, on the quality and quantity of the medical work, and on the job satisfaction of general practitioners is still not available. We present a number of suggestions regarding the use of electronic communication between the general practitioner and the patient. The importance of providing clear, in-depth information to the patient about the use of medical IT communication is underlined. The aspect of data-security is evaluated, and for lack of precise guidelines from health officials it is our suggestion that the report from the Danish Ministry of Finance regarding data-security in public administration is consulted. As to data-access, doctors and patients should be placed on two different safety-levels. It's suggested that doctors should be equipped with a digital key, whereas patients should use a pin code and their social security number. The use of traditional e-mail is dissuaded when exchanging sensitive, person-related information. The importance of valid evaluation of new IT functions is underlined.
We suggest a method for embedding scale-free networks, with degree distribution Pk approximately k(-lambda), in regular Euclidean lattices accounting for geographical properties. The embedding is driven by a natural constraint of minimization of the total length of the links in the system. We find that all networks with lambda>2 can be successfully embedded up to a (Euclidean) distance xi which can be made as large as desired upon the changing of an external parameter. Clusters of successive chemical shells are found to be compact (the fractal dimension is df=d), while the dimension of the shortest path between any two sites is smaller than 1: dmin=(lambda-2)/(lambda-1-1/d), contrary to all other known examples of fractals and disordered lattices.
A network is said to show assortative mixing if the nodes in the network that have many connections tend to be connected to other nodes with many connections. Here we measure mixing patterns in a variety of networks and find that social networks are mostly assortatively mixed, but that technological and biological networks tend to be disassortative. We propose a model of an assortatively mixed network, which we study both analytically and numerically. Within this model we find that networks percolate more easily if they are assortative and that they are also more robust to vertex removal.
