significant economic restrictions compared with developed countries. The quantity and quality of scientific literature relating to pathogenic microorganisms are important indexes or parameters for evaluating the level of study and the degree of attention
The holy grail of quantitative assessment of information production processes has been to find a single meaningful indicator from the quantity data (the number of papers P published), or from what we have
in my teaching, which is predominantly qualitative, not quantitative. It is that distinction that I would like to discuss with you today.
On quantity and quality

The quantity and quality of scientific output of the topmost 50 countries in the four basic sciences (agricultural & biological
sciences, chemistry, mathematics, and physics & astronomy) are studied in the period of the recent 12 years (1996–2007). In
order to rank the countries, a novel two-dimensional method is proposed, which is inspired by the H-index and other methods
based on quality and quantity measures. The countries data are represented in a “quantity–quality diagram”, and partitioned
by a conventional statistical algorithm into three clusters, members of which are rather the same in all of the basic sciences.
The results offer a new perspective on the global positions of countries with regards to their scientific output.
