Moving away from simple data sharing within the science community towards cross-organizational collaboration scenarios significantly increased challenges related to security and privacy. They need to be addressed in order to make cross-organizational applications such as collaborative working environments a business proposition within communities such as eHealth, construction or manufacturing. Increasingly distributed scenarios where many different types of services need to be combined in order to implement semantically enriched business processes demand new approaches to security within such dynamic Virtual Organizations. The (...) allocation of access rights need to be possible in an easy and controlled way in order to allow inexperienced users to maintain the information and ensure compliance e.g. with legal and privacy related regulations. In this paper the focus is how security concepts originating from the Grid domain have been applied for collaborative working environments. The chosen scenarios are a Virtual Laboratory for Infectious Diseases (ViroLab) and different collaborative environments from the engineering domain as defined within the CoSpaces project. The requirements from these scenarios are analyzed and a security model enabling such dynamic, secure and trustworthy collaborations is presented. (shrink)
BACKGROUND -/- In biomedical ontologies, mereological relations have always been subject to special interest due to their high relevance in structural descriptions of anatomical entities, cells, and biomolecules. This paper investigates two important subrelations of has_proper_part, viz. the relation has_grain, which relates a collective entity to its multiply occurring uniform parts (e.g., water molecules in a portion of water), and the relation has_component, which relates a compound to its constituents (e.g., molecules to the atoms they consist of). -/- METHOD -/- (...) We distinguish between four kinds of complex entities and characterize them in first order logic. We then discuss whether similar characterizations could be given in description logics, and finally apply the results to mixtures. -/- RESULTS -/- At first sight, collectives and compounds seem to be disjoint categories. Their disjointness, however, relies on agreement about what are uniform entities, and thus on the granularity of description. For instance, the distinction between isomeric subtypes of a molecule can be important in one use case but might be neglected in another one. We demonstrate that, as implemented in the BioTop domain upper level ontology, equivalence or subsumption between different descriptions of same or similar entities cannot be achieved. Using OWL-DL, we propose a new design pattern that avoids primitive subrelations at the expense of more complex descriptions and thus supports the needed inferences. (shrink)
The paper studies Heidegger's reading of the poet Stefan George (1868-1933), particularly of his poem "Das Wort" (1928), in the context of Heidegger's narrative of the history of metaphysics. Heidegger reads George's poem as expressing certain experiences with language: first, the constitutive role of language, of naming and discursive determination, in granting things stable identities; second, the unnameable and indeterminable character of language itself as a constitutive process and the concomitant insight into the human being's dependency on language and (...) her incapacity to master in subjectively. Heidegger characterizes this experience as "transitional" (übergänglich). It is shown that in Heidegger's historical narrative, this places George's poem in the ongoing transition (Übergang) from the Hegelian and Nietzschean end of metaphysics to a forthcoming "other beginning" of thinking.

On the basis of the works The Notion of Moral Good and Evil in Contemporary Philosophy and Cant Stefan Baley’s views on social morality are analysed. It is shown that Baley supports conscious ethical creativity and the responsibility of the individual to society and to himself. It is proven that Baley follows the ethical principles of the Lvov-Warsaw philosophical school. Kazimierz Twardowski required following these principles as well.
Este artigo propõe-se a fazer uma leitura da obra Brasil, um país do futuro, do escritor vienense Stefan Zweig, ressaltando o quanto o discurso empregado pelo autor está revestido de certo aspecto profético quando fala do Brasil. Seu desejo de querer ver no Brasil da década de 1940 uma terra livre das intolerâncias e violências que assolavam a Europa de então, fustigada pela 2ª Guerra Mundial, fez com que Zweig revivesse a imagem mitológica de que o Brasil era uma (...) terra paradisíaca, um éden reencontrado. A descrição que faz do Brasil, mais que otimista, adquire um aspecto profético quando o autor reforça que a harmonia e paz reinantes no país faziam deste o locus para o acontecimento de um futuro utópico, messiânico. Curiosamente o escritor/profeta, muitas vezes, trai suas profecias, projetando no Brasil valores de sua Europa e às vezes chega mesmo a se contradizer no que tange à questão da tolerância e harmonia que via no Brasil. Palavras-chave: Stefan Zweig; Literatura de viagem; Profetismo; Intolerância; Messianismo. ABSTRACT This article makes a reading of Viennese writer Stefan Zweig’s book Brasil, um país do futuro (Brazil, a country of the future), pointing out how far the author’s discourse is endowed with certain prophetical aspects when it refers to Brazil. His desire to see Brazil, in the 40’s, as a land free from the intolerance and violence that devastated Europe during World War II made Zweig revive the mythological image of the country as a paradisiacal land, a rediscovered Eden. His description of Brazil, rather than optimistic, acquires a prophetical aspect when he emphasizes the fact that the prevailing harmony and peace of the country made it a locus for the advent of a messianic and utopian future. Curiously, the writer/prophet often betrayed his prophecies, projecting in Brazil old European values, and sometimes contradicting himself as to the issue of tolerance and harmony that he witnessed in Brazil. Key words: Stefan Zweig; Voyage literature; Prophetism; Intolerance; Messianism. (shrink)
Charles S. Peirce’s conception of abductive reasoning became a hot topic in the philosophy of science after World War II, when N. R. Hanson suggested that abduction is a logic of discovery, Gilbert Harman argued that all types of inductive reasoning can be reduced to inference to the best explanation, and Howard Smokler suggested that abduction as inverse deduction is an important method of confirmation. Abduction has been a popular theme also in Artificial Intelligence. Illustrations and examples of abduction have (...) been sought in everyday life, detective stories, and many scientific disciplines from astronomy to medicine. Iddo Tavory and Stefan Timmermans have published a book on qualitative... (shrink)
In his novel “Dolina Radości” [“Valley of Joy”] Stefan Chwin tackles the subject of metamorphoses. In this article I will talk about the issue of transformations in “Dolina radości”. The hero of the novel is a makeup-artist and that is why metamorphoses are at the center of the action. Noteworthy are also transformations connected with the most important political events and the most important places in Europe in the 20th century for example in the Polish city of Gdańsk which (...) Chwin writes about. The events of December 1970 are described in an episode of the novel but are a very important element of the whole book. This article first presents references to German literary works which are the part of the literature of German-Polish dialogue. (shrink)
Ştefan Aug. Doinaş and Basarab Nicolescu, two great spirits related through the generosity of the humanist vision, met, held an epistolary dialogue and had common projects. Doinaş commented upon a few of the innovative concepts proposed by Basarab Nicolescu and he also aesthetically transfigured, in literary pages, certain concepts of transdisciplinarity.
The article is a critical response to Stefán Snævarr’s “Pragmatism and Popular Culture: Shusterman, Popular Art, and the Challenge of Visuality.”In its first part, I attempt to prove that several of Snævarr’s claims about popular culture and new media, which form the basic premises of his diagnosis of the alleged intellectual decline of the West, are either dubious or wrong. Moreover, in the context of this diagnosis, Snævarr levels some serious accusations against Richard Shusterman’s theory of popular culture, which, I (...) believe, are ungrounded and do not do justice to the latter’s approach. Henceforth, the remainder of the article is devoted to explaining in which aspects Snævarr’s interpretation of Richard Shusterman’s theory is misguided. (shrink)
In his Menschenwürde nach Nietzsche: Die Geschichte eines Begriffes (Human Dignity According to/after Nietzsche: The History of a Concept), Stefan Lorenz Sorgner conceives a bold plan and executes it remarkably well, with noteworthy results. His plan entails describing four paradigmatic notions of human dignity, then presenting Nietzsche’s critical evaluation of the notion of human dignity in relation to the four paradigms, and finally, reflecting on Nietzsche’s criticism in a way that embraces much of it and, consequently, largely rejects the (...) humanist notion of the dignity of man. Sorgner takes the additional steps of arguing for a posthumanism to replace the outmoded humanist notion of human dignity. Each phase .. (shrink)
The subject of Stefan Collini's Absent Minds is a “rich tradition of debate about the question of intellectuals” in twentieth-century Britain, in particular debate about “their absence or comparative insignificance” . The debate begins with the Dreyfus Affair and its unpredictable British reception , simmers intriguingly through the 1920s and 1930s, and becomes positively effervescent in the 1950s, perhaps because of a new democratization of the public sphere. Collini is less interested in the possible historical causes than in the (...) rhetorical structure that persists, swirling around figures as different as T. S. Eliot, R. G. Collingwood, George Orwell, A. J. P. Taylor, and A. J. Ayer, each of whom gets a full-length profile. Other chapters mix shorter profiles—for example, the devastatingly funny discussion of Colin Wilson and the authorities who briefly and embarrassingly made him a star in their firmament—with synthesis of the debate over intellectuals at different scales and in different national settings. Coming closer to the present, Collini admires Edward Said for what he did as an intellectual while disputing what he said about intellectuals—a celebration of rigorous exile from all social belonging, which could only leave the category of the intellectual looking almost totally uninhabited. The move turns out to be characteristic: it is as if Collini felt he could win a proper admiration for what intellectuals do only by rejecting most of their self-images, or evasion thereof. (shrink)
«Existe-t-il une argumentation juridique?», c’est la question à laquelle tente de répondre l’ouvrage de Stefan Goltzberg, intitulé explicitement L’argumentation juridique. Si l’auteur commence son ouvrage en posant directement la question, on en cherche aussitôt, par un réflexe de «juriste», la définition. Et il faut probablement lire l’intégralité de ce petit ouvrage pour voir se profiler une définition de l’argumentation juridique. Or, au cours de cette lecture Stefan Goltzberg nous montre en quoi chercher la définition, la poser, est déjà (...) une marque argumentative (p. 25) et certainement une marque de l’argumentation juridique. Or, Stefan Goltzberg n’est pas juriste de formation.

En 1934, pour justifier son silence face au nazisme, Stefan Zweig publie un essai historique sur Érasme qui est en même temps une apologie. Pour camper l’humaniste, son alter ego, il se fonde sur la biographie rédigée par Johan Huizinga. Par contre, Luther, l’irréductible opposant d’Érasme, disparaît presque entièrement sous la figure de Hitler, et n’a guère de consistance historique.In 1934 Stefan Zweig published, in order to justify his silence towards Nazism, an historical essay about Erasmus, which was (...) at the same time an apology. In order to portray the humanist, his alter ego, he based himself on the biography written by Johan Huizinga.

To what end should or do we pursue philosophy and how? Meta-philosophical questions along these lines have gained more and more interest recently. The collected volume "Erkenntnistheorie — Wie und wozu?" (Engl.: "Epistemology — How and to what end?") aspires to raise and tackle issues addressing the meta-epistemological questions "How is epistemology practiced and to what end?". Although this aim sounds like a descriptive meta-epistemological endeavor, it is not surprising that many authors rather argue for normative claims surrounding the questions (...) "How and to what end should epistemology be pursued?". This review provides an overview on the collected volume and offers a critical evaluation of its overall achievement. (shrink)
