Bibliometria

The bibliometra is a part of the cienciometra that applies mathematical and statistical methods to all the Literature of scientific character and to the authors produces that it, with the aim of studying and analyzing the scientific activity. For it aid of laws bibliometricses, cradles in the regular statistical behavior that throughout the time the different elements have shown that comprise of Science. The used instruments to measure the aspects of this social phenomenon are the bibliomtricos indicators, measures that provide information on the results of the scientific activity in anyone of their manifestations. Laws bibliometricses Law of exponential growth Derek J. of Price Plaice stated that the growth of the scientific information very takes place to a rate superior with respect to other social phenomena, but very similar to other observable phenomena in natural contexts, like the biological processes. This growth is so, that each 10-15 years the existing information duplicate with an exponential growth, although this depends to a great extent on the knowledge area which it is. As well, it proposed several stages: a phase of exponential growth proper, in which the rate of growth is proportional to the sample size, and a phase of linear growth, in which the rate of growth is constant or independent of the size of the system. The stages are the following: Phase 1: precursors Phase 2: exponential growth Phase 3: linear growth Phase 4: collapse of the scientific field Nevertheless, not only scientific Literature grows of exponential form, but also the number of investigators, reason why the first conclusion that obtained Price of the exponential growth was the contemporaneidad of science, expression that reflects the phenomenon that consists of which the number of scientists at present constitutes almost the total of which they have existed in the past the more the present ones, being the number of cienfficos of the past an almost irrelevant proportion in front of this number present.
