Th e essay follows a certain symmetry that is between the dissident organization Charter 77 (founded in Czechoslovakia in 1977) and the current Czech radical left. Th e essay works from the assumption that the defi nition of “systems” is more important than the nature of these “systems.” One way to understand the issue is to look at the relationship between Charter 77 and the Western radical left of its day, which provides the ideological antecedent of today’s Czech left. But in the contemporary political context, paradoxically, the position of the radical left is structurally moving away from that of the left that was a part of Charter 77 and is coming closer to that of the anti-communist constituents of Charter 77 and to the cultural underground that remained outside Charter 77. Evidence of the continuity between those tendencies can be seen in the police repression of recent years, which points to similarities in how the police view representatives of these diff erent “antisystemic” movements. But perhaps the most striking point of comparison between the dissidents and today’s left can be seen in their separation from majority society and in their ambition to forge something like that society’s moral conscience. Th is leads to a situation known in the Czechoslovak dissent of the 1970s and 1980s as the “dissident ghetto.” Th e notion of the self as a holder of knowledge of the true nature of things, which enables the self to preserve its moral integrity in relation to the “system,” appears to be of no less signifi cance to the present radical left than it was to Charter 77.
Opportunities and risks following current European elections and maintaining and improving the health of citizens in EU countries was a major theme of the EHFG annual conference in October in Gastein, Austria. The Ebola crisis in six African nations, with about 14,000 reported cases and 4,900 deaths, was another topic of discussion by the 600 leading experts in attendance. The World Health Organization states 4.7 million people could be infected and 1.2 million people could die from Ebola by June 2015. The crisis is not just an epidemic, it is a systemic failure of our global health care model, according to experts. Moreover, it is a failure on governance, international development assistance, but primarily on the failure to take immediate action. and Marina Hužvárová.
Two 10-μm interplanetary dust particles collected in the stratosphere, have been analyzed with X-ray fluorescence excited by white synchrotron radiation (SYXFA) at the HASYLAB (DESY) in Hamburg. The measured abundances of the minor and trace elements with 16 < Z < 76 are in good agreement with abundances determined by PIXE analysis [1] of the same particles.
The results demonstrate that SYXFA is indeed a powerful
non-destructive technique for multi-element analysis of
micron-sized samples. Moreover we find that the combined
application of two such techniques, SYXFA and PIXE, to the same valuable particle lends high credibility to the results.
A possible influence of comets on the growth of heavy elements abundance suggested several years ago by Tinsley and Cameron is shortly reviewed. Such an effect would be significant if the formation of comets produce cometary material equivalent to 0.01 - 0.02 M per one solar mass. In the view of current hypothesis of the formation and structure of cometary nuclei the role of comets should be considered as one of the possible moderators of the Z value variation during the chemical evolution of our Galaxy.
