A global comparison of Czech and Slovak academic journals based on their Impact Factor (IF) and Article Influence Score (AIS)
Münich, Daniel ; Škoda, Samuel
We compare the scores in the widely used citation index of academic journals known as Impact Factor (IF) with the lesser known but more sophisticated index Article Influence Score (AIS). There is a positive correlation between the relative IF and AIS scores within fields, but the spread is quite high. The difference between the IF and AIS scores is caused by differences in the extent of journal self-citation and in the academic importance of the journals from which journal articles are cited. Czech publication output in relatively major journals tends to be concentrated in journals with a lower AIS than IF. These articles also tend to be concentrated in a rather small number of international journals. In many fields, Czech publication output is concentrated in Czech and Slovak journals, most of which have relatively low AIS and IF. The IF and AIS of some Czech journals are entirely outside the natural range of scores worldwide.

Quality of publication output of scientific fields in Slovakia: an international comparison
Jurajda, Štěpán ; Kozubek, Stanislav ; Münich, Daniel ; Škoda, Samuel
This study covers in detail the publication output in scientific journals in Slovakia, based on articles published in the years 2010 – 2014 and included in the Web of Science (WoS) database and compares it with the output of 11 different countries. For our comparison, we have used the narrowly defined scientific fields used by the WoS to categorize the journals included in the database. The study compares both total publication output and outstanding publication output, i.e. the number of articles published in top scientific journals in the given field, based on their reputation in the academia.

A national comparison of the academic publication output of the Czech Academy of Sciences: quantity vs quality and co-authorship
Jurajda, Štěpán ; Kozubek, Stanislav ; Münich, Daniel ; Škoda, Samuel
This study maps out in detail the contribution made by the Czech Academy of Sciences (CAS) to the publication output of the Czech Republic for journals listed in the Web of Science (WoS) database. The comparison covers not only the share of the total publication output, but also the share of the excellent publication output, i.e., publications in top-tier journals of respective fields enjoying the most academic prestige. A comparative look at the period 2010-2014 shows that in the vast majority of scientific fields with representation from the CAS scientific teams, the CAS is significantly more focused on publishing in the most prestigious international journals of the WoS database than are others in the Czech Republic. Research cooperation by the CAS in the form of co-authorship takes place at the national level in various fields with differing levels of intensity, as well as differing in the qualitative focus of such cooperation. The sources for this study include the unique bibliometric data processed during the 2015 exercise, the ‘R&D Evaluation of CAS units for 2010-2014’.\n\n

Czech research centres' publication performance in the period 2009-2013, by field of research
Jurajda, Štěpán ; Kozubek, Stanislav ; Münich, Daniel ; Škoda, Samuel
Evaluating Czech research institutions is largely reduced to automatized scoring of R&D otputs. The sole exception is the practice of the Czech Academy of Sciences. The results of the government’s evaluation of research centres, in the form in which they are processed and officially presented to the public, have little informational value for the management of the R&D system and individual research workplaces. At the same time, the system (of data collection about the R&D results, verification and basic classification) offers several unused possibilities, to convey valuable information about the quantity and the quality of research workplaces' publication performance both to the academic community and to the broader public. Our overview exploits these possibilities for results published in journals listed in the Web of Science (WoS) database. The presented comparison is an update of the IDEA study (2015), the publication performance comparison of Czech research centres, mainly of universities and institutes of the Czech Academy of Sciences, in the period of 2009-2013. The underlying logic of the updated comparison, its advantages, disadvantages, limitations and shortcomings remain more or less the same as before, therefore we refer the reader to the detailed explanations in the aforementioned study. The main change from the previous comparison (besides shifting the five-year window by one year) is the usage of an alternative citation index: while our previous comparison differentiated results from journals by the Impact Factor index, the updated comparison uses the Article Influence Score, which weighs citations according to their importance.

An international comparison of the quality of academic publication output in the Czech Republic
Jurajda, Štěpán ; Kozubek, Stanislav ; Münich, Daniel ; Škoda, Samuel
In our recent study (IDEA No. 5/20154) we have compared the publication output of various Czech research institutions by individual disciplines. The comparison was based on the relative output of institutions working in specific science branches within the Czech Republic, and had no way of indicating which institutions in the Czech Republic were on par with international research and which were lagging behind. Even though an institution is not at the top in its field within the Czech Republic, the quality of its research may still be on par with international research, as the particular branch of science is highly advanced in the Czech Republic. Therefore, this study is a first step toward comparing the research output of Czech institutions on an international level. We have compared the publication output of entire scientific fields in the Czech Republic to the same fields in other countries, basing our comparison on articles published in the years 2010–2014 and included in the Web of Science (WoS) database. The comparison includes eleven small and medium-sized countries, only one of which has English as its official language: five European countries belonging to the so-called former Soviet bloc, four Western European countries, and two non-European countries.

An international comparison of the quality of academic publication output in the Czech Republic
Jurajda, Štěpán ; Kozubek, Stanislav ; Münich, Daniel ; Škoda, Samuel
In the recent study Jurajda a Münich (2015) we presented a field-by-field comparison of Czech research publication output. This comparison of the relative strength of output by research institutes in each field within the Czech Republic (CR), could not comment on which Czech institutes are working at international level, and which lag behind their foreign counterparts. It is possible, for example, that an institute that is not at the forefront of its field in the CR may nevertheless be performing research at a standard comparable with international competitors, because it is working in a field in which the Czech Republic is performing very high level research. In this study we offer a first step towards comparing the research output of Czech institutes on an international scale: we compare the publication output of each research field, overall, in the Czech Republic with its international equivalent. Our comparison is based on articles published between 2010 and 2014 which are included in the Web of Science (WoS) database. The comparison includes eleven small and medium sized countries, only one of which has English as its native language. Five of the countries are European countries previously within the Soviet bloc, four are Western European countries and two are non-European countries.
