Les migrations se font maintenant plutôt vers les pays du Sud, refuges de 80 % des demandeurs d’asile. 4 % des Brésiliens sont étrangers, ce qui est faible du fait d’une législation défavorable élaborée pendant la dictature. Les immigrants viennent de Colombie et du Congo, après être venus d’Angola. Ces derniers se sont établis dans le quartier le plus pauvre de Rio. Malgré leur pauvreté, les étrangers participent par leur désir de changement à la nouvelle multitude locale.

Les etudes reunies dans ce volume sont consacrees a l'interpretation des theses principales que defend Aristote en plaidant pour l'exercice d'une veritable politique par le citoyen juste. Ce sont des theses d'un enjeu redoutable. Elles impliquent le plus souvent les conceptions que se fait Aristote des vertus morales et intellectuelles composant le portrait de l'homme, non seulement heureux, mais susceptible d'apporter le bonheur a la Cite. Elles engagent aussi a considerer l'unite profonde que forment, chez Aristote, l'ethique et la politique. (...) A cote d'etudes recemment publiees par l'auteur, le receuil contient d'importants inedits qui font le point sur des questions disputees. L'ensemble peut introduire aux differents aspects de la pensee ethico-politique d'Aristote qui font, aujourd'hui encore, son actualite. (shrink)

Quasi-Nelson logic (QNL) was recently introduced as a common generalisation of intuitionistic logic and Nelson's constructive logic with strong negation. Viewed as a substructural logic, QNL is the axiomatic extension of the Full Lambek Calculus with Exchange and Weakening by the Nelson axiom, and its algebraic counterpart is a variety of residuated lattices called quasi-Nelson algebras. Nelson's logic, in turn, may be obtained as the axiomatic extension of QNL by the double negation (or involutivity) axiom, and intuitionistic logic as the (...) extension of QNL by the contraction axiom. A recent series of papers by the author and collaborators initiated the study of fragments of QNL, which correspond to subreducts of quasi-Nelson algebras. In the present paper we focus on fragments that contain the connectives forming a residuated pair (the monoid conjunction and the so-called strong Nelson implication), these being the most interesting ones from a substructural logic perspective. We provide quasi-equational (whenever possible, equational) axiomatisations for the corresponding classes of algebras, obtain twist representations for them, study their congruence properties and take a look at a few notable subvarieties. Our results specialise to the involutive case, yielding characterisations of the corresponding fragments of Nelson's logic and their algebraic counterparts. (shrink)

Forcing extensions yield models of ZFC in which a long sequence of club subsets of ω 1 has the following property: every subsequence of size ℵ 1 has a finite intersection.

Avery’s et al. ’s 1944 paper provides the first direct evidence of DNA having gene-like properties and marks the beginning of a new phase in early molecular genetics (with a strong focus on chemistry and DNA). The study of its reception shows that on the whole, Avery’s results were immediately appreciated and motivated new research on transformation, the chemical nature of DNA’s biological specificity and bacteria genetics. It shows, too, that initial problems of transferring transformation to other systems and prominent (...) criticism of its results nurtured skepticism. Avery’s experiment was downplayed and neglected particularly by many of those scientists who worked in the new fields of biochemical and biophysical genetics, genetic phage, and TMV research. This was not due to the fact that the implications of the paper could not be connected to generally accepted knowledge. Contrary to a widespread belief, the assumed uniformity of DNA as opposed to proteins was not used as an argument against the validity of Avery’s et al.’s finding. The indifference rather reflected, among other things, the disciplinary gap between the chemically oriented microbiologists and the old and new geneticists who remained committed to genetic and physical methods (in particular x-ray studies) and clung to the assumption that proteins were the sole carriers of biological specificity. The responses to Avery’s et al.’s paper show how different research interests in the areas between microbiology, genetics, and biochemistry interacted with the prejudices, dogmas, individual farsightedness or short-sightedness, and scientific authority during a pivotal period of early molecular biology.

There’s a possibly more interesting general question: does technology transform and extend the mind and our mental powers? In a widely discussed 1998 paper titled “The Extended Mind”, Andy Clark and David Chalmers argue that mind and cognition can extend outside the head and can include items and processes in the world. In their thought experiment, Otto has alzheimer’s syndrome but does not lose his ability to function because he records information he learns in a notebook that he always carries. (...) Thus, C&C claim, Otto continues to have beliefs. The notebooks function as his memory. C&C propose a "parity principle": a part of the world is part of a cognitive process if it "functions as a process which, were it done in the head, we would have no hesitation in recognizing [it] as part of the cognitive process .... Cognitive processes ain't (all) in the head!" (in Menary p. 29, original emphasis). (shrink)

The paper takes a Critical Discourse Analysis angle and joins Social Media Studies and Religious Studies perspectives of Computer Mediated Communication material to examine such strategies of online interpersonal communication as may foster civic solidarity on social networks sites over local incidents with national and international media coverage. Computer mediated discourse is often underpinned by ideological antagonism especially when tackling social, political, cultural and even religious issues. Our topic choice was occasioned by an infelicitous episode – a fire in a (...) local venue hosting a rock concert that resulted in a high number of casualties and fatalities. The tragic episode triggered some polarized and highly opinionated positioning in the social media, both independent of and/or in retaliation to media sourced accounts and personal posts. We analyzed qualitatively authentic CMC material as well as edited media inputs in order to establish if and how the networked, yet generationally diverse, public achieve symbolic solidarity through reactive and correlated digi-participation where sociocultural identities become tangent to such ecclesiastic issues as became salient and were up-cycled in the local political conjecture.
