Since 2017, Module 2 of the Czech national research evaluation system (Methodology 2017+) has been based on the bibliometric analysis of articles indexed by the multidisciplinary database Web of Science (WoS) and which were also assigned an Article Influence Score (AIS) value. This competition has exposed the humanities to new challenges as the articles with an impact factor are not the main, or the only, publishing channel. Using several perspectives, we analysed the publication performance of the data in the FORD 6.1 – History and archaeology – to verify the possibilities of bibliometrics and to gain the necessary context for the current results of the national evaluation. Contrary to widespread belief, we are convinced that bibliometrics can be applied to the humanities provided the appropriate approach is applied. According to our findings from the period 2015–2019, the discipline proved to be strongly interlinked and have shown increasing coverage in the WoS, international cooperation and representation in journals with an impact factor. At the same time, they also use WoS journals without an impact factor (AHCI, ESCI) and other publishing channels outside the WoS. Research evaluation should respect context, diversity of different fields and not apply mechanisms that favour certain disciplines and discriminate against others. Misinterpretation due to inappropriately set criteria could have serious consequences for designing research strategies. At the same time, strategies should not be based on incorrect or outdated assumptions, thus preserving historical publishing patterns. This prevents international communication concerning results in the humanities, which have great potential.
In order to support his revolutionary view on scientific change, Kuhn suggests that there exist two separate aspects of the theory-change from Newtonian to Einsteinian physics that support his incommensurability thesis. For the evidence of his thesis, Kuhn offers the conceptual change in the meaning of the notion of “mass” in the theory-change. And he claims the absence of any neutral observational basis to evaluate the strengths of the two theories. This essay argues that these two cases fail to support his incommensurability thesis.
Earlier results concerning sympathetic flares and time-correlated rádio bursts are compared with the history and dynamics of development of the magnetic situation in active regions with related flaring. An attempt to present observational evidence of the existence of sympathetic flares is made. We are trying to demonstrate that active regions producing such flares are physically related through common dynamical elements whose magnetic fields display parallel evolution.
The aim of this study was to ascertain the persistence of heart rate and blood pressure oscillations at the onset of voluntary apnea in humans and to assess the dependence of the fluctuations` parameters on the chemoreceptor activity. In 24 young subjects (10 males, 14 females, mean age 20.4 years) heart rate (represented by its reciprocal value - RR-intervals), systolic blood pressure (SBP) and diastolic blood pressure (DBP) during controlled breathing (CB) of atmospheric air and oxygen followed by apnea were recorded continuously. The cosine functions were then fitted by nonlinear regression analysis to the heart rate, SBP and DBP oscillations during CB and at the onset of apnea. The parameters of oscillations were different during atmospheric air breathing compared to oxygen breathing. During oxygen breathing there was an increase of the RR-interval oscillations - relative bradycardia and enhanced magnitude of respiratory sinus arythmia. During apnea, the base level of the blood pressure oscillations was higher after breathing of atmospheric air compared o oxygen breathing. At least one cosine-like wave oscillation was present at the onset of apnea in the heart rate, SBP and DBP and the second wave was present in all assessed parameters in at least 70 % of recordings. The oscillations in RR-intervals are, to some extent, independent of blood pressure oscillations. No significant gender differences were found either in the duration of breath holding or in the RR and SBP oscillations parameters., M. Javorka, I. Žila, K. Javorka, A.
