The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Resumo: Considerando o avanço das tecnologias bem como o binômio indissociável formado por ela e pela ciência – e consequentemente atrelados à educação –, configurando práticas enraizadas culturalmente na sociedade atual, o presente artigo traz como objetivo central discutir a relação da técnica (tékhné) com a concepção de homem que se quer formar, à luz das críticas adornianas. Ponderando o imperativo de subverter a ideologia utilitarista da educação, tal reflexão se justifica pela necessidade de compreensão do papel do educador, bem como da instituição escolar, mediante tal avanço nos últimos tempos. Concluindo que esta relação não pode suceder de maneira alienada, acrítica e indiferente, pois uma educação após Auschwitz deve certamente estar receptiva à relevância essencial da tecnologia em um mundo contemporâneo. No entanto, não é o sujeito que está a serviço dela e sim a relação contrária, em que o educando possa valer-se dos recursos tecnológicos como mais uma dimensão do agir humano. Como potente braço prolongado do operari humano, pensada como acontecimento paradigmático na história do ser. Palavras-chave: Theodor Adorno; tecnologia; educação; professor. TECHNOLOGY, SCIENCE AND THE ROLE OF EDUCATION: A CRITICAL CONSIDERATION OF THEODOR W. ADORNO Abstract: Considering the advancement of technologies as well as the inseparable duo formed by her and science - and thus tied to education - setting culturally rooted practices in today's society, this paper aims at discussing the relationship of technique (tékhné) with the concept of man constructed in the light of adornian criticism. Given the imperative to subvert the utilitarian ideology of education. Such reflection is justified by the necessity of understanding the role of the educator as well as the school, by this advance in recent times. Concluding that this relationship can not succeed in an alienated, uncritical and indifferent way, since an education after Auschwitz should certainly be receptive to the special importance of technology in a contemporary world. However, it is not the subject who is in her service, but the opposite relationship, in which the student can make use of technological resources as another dimension of human action. A powerful extended arm of human operari, thought as paradigmatic event in the history of being. Keywords: Theodor Adorno; technology; education; teacher.

The paper focuses on the history of the movement for preservation of geological heritage of Ukraine, closely related to the history of geoconservation in Europe; determines the relationship of the extent of geodiversity and geological structure of a certain country, political system, historical traditions and attitude towards wildlife and inanimate nature. Despite the fact that geodiversity and biodiversity have always been in parallel, traditionally all nations in all the continents have focused more on the preservation of so-called wildlife. The article describes that preservation of the so-called inanimate nature; provides a rather sufficient analysis of literature sources which report on the problem of preserving bio- and geodiversity not only in Ukraine, but also in other countries of Europe. In particular, the combination of biotic and abiotic constituents of nature proved to be an essential aspect in determining the place of the world`s first nature reserve and location of an important centre of Buddhism in Mihintale, Sri Lanka. The start of the movement for preservation of so-called inanimate nature in Europe could, with a certain extent of possibility, be considered the first historical written mention of the subject, which was declared in the 10th Chapter of Third Statute of Lithuania in 1588. That is protection of rivers against artificial change of their banks, change in currents and preservation of large erratic boulders. As an important stage of the beginning of the movement for preservation of the so-called inanimate, can be considered the year 1668, when in Germany the Baumannshöhle cave was preserved. It was first mentioned in the literature in 1565, and in 1646 the cave became an object of tourism. During the analysis of the historical stage related to the movement ProGEO, we emphasizes international events in which the representatives of the Ukrainian ProGEO group took part. Active work of the Ukrainian ProGEO group created conditions for transition to a new level of geoconservation, i.e. determination of the possibility of creating a new category of objects of the Nature-Reserve fund of Ukraine – geological parks (geoparks) as important locations for the development of geotourism and territories of complex conservation of the natural environment.

Current practice in logic increasingly accords recognition to abductive, presumptive or plausible arguments, in addition to deductive and inductive arguments. But there is uncertainty about what these terms exactly mean, what the differences between them are (if any), and how they relate. By examining some analyses ofthese terms and some of the history of the subject (including the views of Peirce and Cameades), this paper sets out considerations leading to a set of definitions, discusses the relationship of these three forms of argument to argumentation schemes and sets out a new argumentation scheme for abductive argument.

The object of this research is the political history of the Ulus of Jochi as a part of the Great Mongol Empire. The subject of this is the Eastern policy of Mengu-Timur – the 6th ruler of the Ulus of Jochi (1266-1282). The author examines such aspects of the topic as the relationship of Mengu-Timur with the rulers of the uluses of Hulagu – Abaga, Chagatay – Borak, Ugedei – Kaidu, decisions made by the representatives of the uluses of Jochi, Chagatay and Ugedei in Talas Kurultai. Special attention is given to the analysis of relationship between Mengu-Timur and the ruler of the Central Ulus of Kublai, who founded the Yuan Empire. Comparative analysis is conducted on the written sources and scientific works on the topic. The sequence of events is reconstructed in chronological order. The author agrees with his predecessors that Mengu-Timur became the first sovereign ruler of the Ulus of Jochi. The scientific novelty consists in the conclusion that entitlement of Mengu-Timur as independent monarch was not a decision of Talas Kurultai. In Talas Kurultai in 1269 Kaidu was recognized as the leader of the right wing of the Mongol Empire, which included the Ulus of Jochi, Chagatay and Ugedei. The relations with the Great Khan in Kurultai were not settled, and the independence of uluses was not proclaimed. In the early 1370s, Mengu-Timur was named qayan, i.e. the supreme ruler above the khan. In 1277, Kublai's sons Numugan and Kukju were caught by the rebels, who sent them to Mengu-Timur. He did not support the rebels, but kept the son of Kublai. Since that moment, Mengu-Timur did was not subordinate to Kublai or Haidu, did not interfere into the conflict between them, restraining both of them from military clashes. Although Mengu-Timur maintained peaceful relations with other uluses, he was qayan title was not recognized.

A relação de Hegel com o ceticismo está longe de ser clara. A par de existirem alguns poucos trabalhos sobre o assunto, e de Hegel abordar o tema em várias obras, não está bem determinado se Hegel possui uma teoria global sobre o ceticismo ou se apenas é um mero crítico de posturas céticas clássicas na antiguidade e na modernidade. Em que pese Hegel ser um crítico ferrenho do ceticismo moderno (por ex., em textos como Sobre a relação do Ceticismo com a Filosofia, as Preleções sobre História da Filosofia e a Enciclopédia das Ciências Filosóficas), a sua crítica não se restringe a esta ou aquela forma de ceticismo, mas se funda numa teoria geral do saber que compreende o ceticismo como uma atividade negativa constitutiva da consciência e pretende refutá-lo enquanto ele reifica essa negatividade numa pretensão de verdade. A refutação consiste na descrição do modo como o ceticismo filosófico seria um saber parcial, e por isso auto-refutativo. O presente trabalho pretende sugerir que isto ocorre, sobretudo, na Fenomenologia do Espírito, cujo caráter “fenomenológico” propriamente dito não parece poder ser bem compreendido, sem tomar como pano de fundo o problema do ceticismo. PALAVRAS-CHAVE – Hegel. Fenomenologia. Ceticismo. Refutação. ABSTRACT Hegel’s position towards skepticism is far from being clear. On the one hand, there are just a few studies on the subject and Hegel faces the issue in several of his writings; on the other hand, it is not established yet if Hegel has a global theory about skepticism or if he is just a critic of Ancient and Modern skeptical attitudes. In spite of Hegel being known as a sharp critic of Modern skepticism (for example, in works like On the relationship of skepticism to philosophy, Lectures on the history of philosophy and Encyclopedia of philosophical sciences), his criticism is not restricted to specific forms of skepticism, but it is rather founded upon a general theory of knowledge which takes skepticism as a negative activity constitutive of our natural consciousness and intends to refute the skeptical attitude as that negative activity of self-consciousness is reified and turned out into a special kind of truth claim. Hegel’s refutation consists in describing the way philosophical skepticism would be understood as a partial and self-defeating attitude of knowing. The present study suggests that this procedure is to be seen above all in the Phenomenology of Mind, whose “phenomenological” character cannot be rightly understood without taking properly into account the problem of skepticism. KEY WORDS: Hegel. Phenomenology. Skepticism. Refutation.

Historians of Nigeria have been curious for many years about the relationship between the various states of the southern zone since the sixteenth century. The fact that the area has produced a rich art, has a fairly elaborate set of traditional histories, and has been the subject of some systematic archeological work means that the modern scholar has somewhat more to go on in reconstructing the region's history than just the fairly sparse and disappointing contemporary texts that came out of the early Portuguese contacts and subsequent European trade and navigation. But contemporary documentation for southern Nigeria remains much weaker than that for other African areas, such as the central African zone, Gold Coast, or the western Atlantic coast.Nevertheless, documents have raised problems in understanding the history of the area that cannot be fully solved by recourse to the other sources of information, in spite of the comparative richness of non-documentary sources. One of these documentary problems is the issue of the Ife-Benin relationship as documentated in archeology, contemporary texts, and art history. The problems raised by the relationship between these two southern Nigerian cities ultimately reflects on a much larger set of questions concerning the relationship of all the early states south of the Niger, at a period quite near the origin of the state system that would predominate the rest of the pre-colonial period.

Treatment of persons with psychological difficulties varied in different historical periods, but in its essence remained similar until today. It included an inhumane relationship towards these persons, involuntary treatment through torture, and isolation from society as a kind of punishment for their diversity. It was not until the late 19th century that the relationship of society towards these individuals started to improve gradually, but in the 21st century isolation of these individuals still remained the dominant form of acceptable social solution for the ?problem?, with a somewhat more humane attitude towards them and less cruel treatment. Serbia has followed the trends of treatment of the persons with psychological difficulties from the rest of Europe for centuries, but is still lagging behind the world in the introduction of new methods of treatment. Indeed the first legal solution to regulate the human rights of these people is currently in the process of implementation. The subject of this paper is the treatment of persons with psychological difficulties and the violation of their civil rights. In a subject specific context the goal of the analysis was the historical review of the treatment towards persons with psychological difficulties by doctors, other practicioners and the community in general, with reference to the current situation regarding their treatment within the psychiatric institutions, as well as the legal regulations and the protection of their civil rights.

Covers the long history of the Smithfield animal market and legal reform in London. Shows the relationship of civic improvement tropes, including animal rights, to animal erasure in the form of new foodstuffs from distant meat production sites. The reduction of lives to commodities also informed public abasement of the butchers.
