The cyber sphere forms a fifth domain of activities were interactions between state and non-state actors could happen. It starts to play an important role within the conflicts and hostilities. Especially in these situations, international society does not have a unified view on the question how to deal with the activities in cyberspace. We could see the different forms of abuse of cyberspace also within the crisis in Ukraine. This crisis is a good example of the complexity of the legal approach and the (non)capability of the legal understanding of cyber operations and attacks. The goal of this article is to highlight this complexity and to determine the status of cyber incidents realized in the Ukraine from the perspective of international law., Jozef Valuch, Ondrej Hamuľák., and Obsahuje bibliografické odkazy
Chromosome numbers are given for 16 taxa (and one interspecific hybrid) of Hieracium subgen. Pilosella originating from Central Europe: H. apatelium Nägeli et Peter (2n = 45), H. aurantiacum L. (2n = 36), H. bauhini Besser (2n = 36, 45, 54), H. brachiatum Bertol. ex DC. (2n = 45, 48, 63, 72), H. densiflorum Tausch (2n = 36), H. echioides Lumn. (2n = 18, 27, 36), H. floribundum Wimm. et Grab. (2n = 36, 45), H. glomeratum Froel. (2n = 36, 45), H. guthnickianum Hegetschw. (2n = 54), H. lactucella Wallr. (2n = 18), H. onegense (Norrl.) Norrl. (2n = 18), H. pilosella L. (2n = 36, 45, 54), H. piloselliflorum Nägeli et Peter (2n = 36, 45), H. piloselloides Vill. (2n = 36), H. rothianum Wallr. (2n = 36), H. schultesii F. W. Schultz (2n = 45), and the hybrid H. floribundum × H. aurantiacum (2n = 36). New chromosome numbers are reported for H. brachiatum and H. floribundum. The octoploid cytotype (2n = 72), recorded in H. brachiatum, is the highest ploidy level ever found in plants from the subgen. Pilosella originating from the field. Aneuploidy, rare in this subgenus in Europe, occurs in this hybridogenous species as well: it was recorded in one plant (2n = 48) collected in a hybrid swarm H. pilosella × H. bauhini. The breeding system in H. bauhini, H. brachiatum, H. densiflorum, H. echioides, H. pilosella, H. piloselloides, and H. rothianum was studied. The sexual reproduction of pentaploid H. pilosella is a new observation: it means an increase of diversity in possible reproduction modes of those cytotypes having odd chromosome numbers.
As a result of inconsistencies in morphological characters, Cerastium pumilum and C. glutinosum have been misunderstood or confused in many European floras since the 1960s. In the second volume of the Flora Nordica, a revised treatment of C. pumilum s.l. is provided and this concept is tested here for eastern Central European populations. The cytometric and morphological part of the study is based on living plants from 85 populations in the Czech Republic, Slovakia, Poland, Austria and Hungary. Flow cytometric analyses of the samples revealed two groups differing in ploidy level and corresponding to two cytotypes (a known octoploid, 2n ≈ 72, for C. glutinosum and yet unknown dodecaploid, 2n ≈ 108, for C. pumilum). Eleven morphological characters were scored or measured in plants of known ploidy level and the data set analysed using multivariate statistics (principal component analysis and canonical discriminant analysis); the two morphologically well-separated groups were identical with the two cytotype groups detected by flow cytometry. Based on these results, we suggest treating the detected cyto-morphotypes as the species C. pumilum and C. glutinosum. Our analysis further revealed that the traditionally used characters (glabrous vs. hairy adaxial surface and presence vs. absence of a scarious margin to the tip of the lowermost bracts) are not taxonomically informative. The characters best differentiating the species include indument on the lowermost vernal internodium, length of mature stylodia, length of glandular hairs on sepals and maximum diameter of mature seed. A key for identification of both species is also provided. A revision of almost 1600 specimens deposited in 16 Central European herbaria revealed that the species show different distribution patterns in Central Europe and partial habitat segregation. Specimens from the Czech Republic previously assigned to C. litigiosum were identified as C. pumilum; consequently, C. litigiosum must be removed from the Czech flora.
Petro Shelest (1908–1997), the First Secretary of the Communist Party of the Ukrainian Soviet Socialist Republic and a member of the Politburo of the Central Committee of the Communist Party of the Soviet Union, was one of the strongest advocates of an armed invasion of Czechoslovakia among Soviet leaders in 1968. The Soviet leadership tasked him to maintain contacts with the so-called healthy forces in the Communist Party of Czechoslovakia; in the beginning of August, Secretary of the Central Committee of the Communist Party of Czechoslovakia Vasil Biľak (1917–2014) secretly handed over to him the notorious “letter of invitation” in public lavatories in Bratislava. The author asks a fundamental question whether it is possible to identify a specific Ukrainian factor which stepped into the Prague Spring process and contributed to its tragic end. He attempts to capture Shelest’s position in the decision-making process and describe information that Shelest was working with., To this end, he has made use of reports of the Committee for State Security (Komitet gosudarstvennoi bezopasnosti – KGB) of the Ukrainian Soviet Socialist Republic on developments in Czechoslovakia and reactions thereto among Ukrainian citizens produced in the spring and summer of 1968, which were being sent to Shelest and other Ukrainian leaders. These documents have lately been made available in Ukrainian archives and partly published on the website of the Institute for the Study of Totalitarian Regimes. Their analysis brings the author to a conclusion that they were offering a considerably distorted picture of the situation. Instead of relevant information and analyses, they only present various clichés, ideological rhetoric, inaccuracies, or downright nonsenses. Their source were often members of the Czechoslovak State Security who were often motivated by worries about their own careers and existence and were acting on their own., and The uncritical acceptance of the documents contributed to a situation in which in the leader of the Ukrainian Communists and other Soviet representatives were creating unrealistic pictures of the events taking place in Czechoslovakia, believing that anti-socialist forces were winning, anti-Soviet propaganda was prevailing, and Western intelligence agencies were strengthening their position in Czechoslovakia, and that there was a threat that the events that had taken place in Hungary in 1956 would repeat themselves again. As indicated by his published diary entries and other documents, Petro Shelest was using these allegations both in discussions inside his own party and during negotiations with Czechoslovak politicians. Just like in the case of the leaders of Polish and East German Communists, Władysław Gomułka and Walter Ulbricht, respectively, the principal reason why Shelest was promoting a solution of the Czechoslovak crisis by force was, in the author’s opinion, his fear of “contagion” of his own society by events taking place in Czechoslovakia which the Ukraine shared a border with.
