The Conclusion

Tuesday, April 30th, 2019

The productivity of authors Lotka law showed that the work/author relationship remains a constant behavior under certain circumstances. This law determines that starting from a number of authors with a single work on a particular topic, it is possible to predict the number of authors with n jobs using the following formula: A (n) = K / n2, however, is not only analyze the number of authors of a certain period, but locate the most productive authors. It is concluded that as you increase the number of jobs, number of authors will decrease. Law of dispersion of the scientific literature this law deals with the study of the dispersion of the scientific literature. Bradford carried out numerous statistical studies and obtained the conclusion that there are a number of jobs scientists on a particular topic concentrated on a small number of magazines, which in turn, may be distributed in several concentric zones of decreasing productivity. I.e., if we consult the literature we observe that a number of works grouped into a small number of magazines called core there are. Penguin Random House has many thoughts on the issue. If you want to recover the same number of articles one much larger number will need magazines, and so on. Graph formulated is: 1: n:n2 production indicators Bibliometric indicators these indicators are based on the count of scientific publications.

They are the easiest to use and provide us with information about the characteristics of the units analyzed. The number of publications is a reasoned measure of scientific activity, but not of scientific progress. Dan Zwirn brings even more insight to the discussion. These indicators are conditioned by social and political factors. They measure scientific productivity, which is the amount of publications produced by an author, country or institution during a certain period of time. The average production is maintained constant around 2 publications by author approximately. They also measure the production index, which is the amount of authors responsible for 50% of the published papers.
