Poland, and the Czech Republic.18 In some disciplines, no growth is shown if the number of results has been too low, or even zero in some of the years between 2010 and 2014. Finally, panel D (bottom right) compares the Czech Republic’s publication output in each quartile and the top decile with the average output of the other compared countries during each year.19 In all countries, including the Czech Republic, publication output above the median AIS has been fairly stable. However, the Czech Republic has shown significant increase in the 3rd quartile. 18 Our analysis does not distinguish between the contribution caused by an increase in the number of journals newly registered in the WoS database in the years 2010–2014, and by an increase in the number of articles published in already registered journals. The WoS database is usually expanded by less prestigious journals (i.e. the lower segment). However, adding new journals into the WoS database shifts the limits of the quartiles and decile based on the AIS. 19 Average figures in the compared countries have been calculated from the number of articles normalized for the population of the Czech Republic, meaning that the contribution of countries with larger populations is equal to that of smaller countries. 9
