In this paper, we review and connect the three essential conditions needed by the collapse model to achieve a complete and exact formulation, namely the theoretical, the experimental, and the ontological ones. These features correspond to the three parts of the paper. In any empirical science, the first two features are obviously connected but, as is well known, among the different formulations and interpretations of non-relativistic quantum mechanics, only collapse models, as the paper well illustrates with a richness of details, (...) have experimental consequences. Finally, we show that a clarification of the ontological intimations of collapse models is needed for at least three reasons: (1) to respond to the indispensable task of answering the question ’what are collapse models (and in general any physical theory) about?’; (2) to achieve a deeper understanding of their different formulations; (3) to enlarge the panorama of possible readings of a theory, which historically has often played a fundamental heuristic role.

In Thomas Thomson's System of chemistry of 1802 Bergman and Scheele are actually considered as creators of the analytical concept of an element. With regard to this, a detailed investigation of the work of Bergman and Scheele shows that Thomson's statement contains mistakes as well as inadmissable simplifications and generalizations. It is correct, however, that Bergman in 1774–1777 specifically anticipated in essential aspects the analytical element concept proposed by Lavoisier in 1787–1789.

The Gamer’s Dilemma consists of three intuitively plausible but conflicting assertions: (i) Virtual murder is morally permissible. (ii) Virtual child molestation is morally forbidden. (iii) There is no relevant moral difference between virtual murder and virtual child molestation in computer games. Numerous attempts to resolve (or dissolve) the Gamer’s Dilemma line the field of computer game ethics. Mostly, the phenomenon is approached using expressivist argumentation: Reprehensible virtual actions express something immoral in their performance but are not immoral by themselves. Consequentialists, (...) on the other hand, claim that the immorality of virtual actions arises from their harmful consequences. I argue that both approaches have serious difficulties meeting the moral challenge posed by the Gamer’s Dilemma. They tend to confuse the morality of in-game actions either with the morality of their real-world counterparts or with the morality of games as objects. Following this critical analysis, I will develop a Kantian argument and defend it against two objections. So far, deontological responses to the Gamer’s Dilemma have been sought in vain. Yet, with Kant, its moral challenge can be met by looking at the gamer’s reasons. From this perspective, the Gamer’s Dilemma is based on a false assumption: the moral status of gaming acts does not derive from a normative equation with their real-world counterparts but only from their justifications.

Garry Young has made three objections against Sebastian Ostritsch’s endorsement view on the immorality of computer games. In this paper, we want to defend the endorsement view against all three of them.

This is one of the most important books on quantum mechanics ever written for lay readers, in which an eminent physicist and successful science writer, Heinz Pagels, discusses and explains the core concepts of physics without resorting to complicated mathematics.

This junior/senior level text is devoted to a study of first-order logic and its role in the foundations of mathematics: What is a proof? How can a proof be justified? To what extent can a proof be made a purely mechanical procedure? How much faith can we have in a proof that is so complex that no one can follow it through in a lifetime? The first substantial answers to these questions have only been obtained in this century. The most (...) striking results are contained in Goedel's work: First, it is possible to give a simple set of rules that suffice to carry out all mathematical proofs; but, second, these rules are necessarily incomplete - it is impossible, for example, to prove all true statements of arithmetic. The book begins with an introduction to first-order logic, Goedel's theorem, and model theory. A second part covers extensions of first-order logic and limitations of the formal methods. The book covers several advanced topics, not commonly treated in introductory texts, such as Trachtenbrot's undecidability theorem. Fraissé's elementary equivalence, and Lindstroem's theorem on the maximality of first-order logic. (shrink)

This contribution to the special issue is an historical account of Paulo Freire’s pedagogical and administrative praxis before his forced exile in 1964. It relies on interviews collected during a field trip in 1976, a conversation with Paulo Freire in Geneva one year later and on the secondary literature up to date. Being the head of the first Extension Service of a major Brazilian university in the early 1960s gave Freire and his collaborators the space and time to experiment with (...) the today world famous literacy method bearing his name. The concept of ‘Field of Cultural Production’ (Bourdieu) is used to elucidate better Freire and his team’s avant-gardist production within the spaces opened up by Brazil’s popular movements in the early sixties. The contribution shows how the ‘Paulo Freire System’ developed in the praxis of a cultural movement and received its academic consecration in an incremental and eclectic style. (shrink)

Das Buch ist eine fur den gebildeten Laien verstandliche Einfuhrung in die historische Entwicklung der Grundlagenforschung der Mathematik von der Axiomatik Euklids uber die Prazisierung der Analysis in der Neuzeit und die durch die Entwicklung der Mengenlehre verursachte Grundlagenkrise der Moderne (ausfuhrliche Behandlung der sogenannten Antinomien) bis zu den Godelschen Satzen uber formale Systeme. Da im Gegensatz zu den modernen Umwalzungen in den Grundlagen anderer Wissenschaften (z.B. der Physik) die dazu parallele Erscheinung in der Mathematik immer noch nicht allgemein bekannt (...) ist, wird dabei ein Beitrag geliefert zum Verstandnis des Wesens und der philosophischen Bedeutung der modernen Mathematik.".

The article analyzes the anti-Islamic polemical discourse of Nicetas of Byzantium, one of the most important Byzantine apologists and polemicists flourishing in the intellectual-theological context of Patriarch Photios in Constantinople. This paper crystallizes the main topics of discussion in Nicetas’ Refutation of the Qur’an and presents his argumentation against Islam.To structure and evaluate the wayNicetas perceives Islam, I have developed a methodology of four thematic categories with correspondent polemical subcategories. This research approach may also serve as a paradigm enhancing further (...) studies on other sources related to Christian-Muslim interfaith dialogue. (shrink)

The most recent work toward compiling a comprehensive database of adenosine‐to‐inosine RNA editing events suggests that the potential for RNA editing is much more pervasive than previously thought; indeed, it is manifest in more than 100 million potential editing events located primarily within Alu repeat elements of the human transcriptome. Pairs of inverted Alu repeats are found in a substantial number of human genes, and when transcribed, they form long double‐stranded RNA structures that serve as optimal substrates for RNA editing (...) enzymes. A small subset of edited Alu elements has been shown to exhibit diverse functional roles in the regulation of alternative splicing, miRNA repression, and cis‐regulation of distant RNA editing sites. The low level of editing for the remaining majority may be non‐functional, yet their persistence in the primate genome provides enhanced genomic flexibility that may be required for adaptive evolution.
