O objetivo deste artigo é mapear as novas modalidades de presença e consumo da música brasileira em Portugal, para além dos formatos vinculados à MPB tradicionalmente consagrados e, a partir de variáveis como o processo de globalização e a reconfiguração das indústrias fonográficas, discutir aspectos do momento contemporâneo como o reordenamento dos fluxos migratórios entre Portugal e Brasil e a inserção desta música nos circuitos turísticos e midiáticos portugueses.
For each integer n ≥ 2, MVn denotes the variety of MV-algebras generated by the MV-chain with n elements. Algebras in MVn are represented as continuous functions from a Boolean space into a n-element chain equipped with the discrete topology. Using these representations, maximal subalgebras of algebras in MVn are characterized, and it is shown that proper subalgebras are intersection of maximal subalgebras. When A ∈ MV3, the mentioned characterization of maximal subalgebras of A can be given in terms of (...) prime filters of the underlying lattice of A, in the form that was conjectured by A. Monteiro.

Visiones antropológicas divergentes en artículos científicos de bioética en Brasil Divergent Anthropological Views in Scientific Articles on Bioethics in Brazil The aim of the study is to characterize Brazilian bioethics outputs anthropologically, specifically scientific articles. The guiding question of this research is: What is the anthropological characterization present in scientific articles on bioethics in Brazil? Prominent bioethical theories show restrictive anthropology indicators; i.e., dignity is given only to members of the human species that have certain attributes, including conscience and self-consciousness, (...) as opposed to comprehensive anthropology indicators in relation to human beings; i.e., dignity is equally assigned to all members of the Homo sapiens species. In conclusion, comprehensive anthropology indicators and theoretical divergence in relation to the origin of life, especially between utilitarianism and personalism, prevail.

The notion of monadic three-valued ukasiewicz algebras was introduced by L. Monteiro (, ) as a generalization of monadic Boolean algebras. A. Monteiro (, ) and later L. Monteiro and L. Gonzalez Coppola  obtained a method for the construction of a three-valued ukasiewicz algebra from a monadic Boolea algebra. In this note we give the construction of a monadic three-valued ukasiewicz algebra from a Boolean algebra B where we have defined two quantification operations and * such (...) that *x=*x (where *x=-*-x). In this case we shall say that and * commutes. If B is finite and is an existential quantifier over B, we shall show how to obtain all the existential quantifiers * which commute with .Taking into account R. Mayet  we also construct a monadic three-valued ukasiewicz algebra from a monadic Boolean algebra B and a monadic ideal I of B. (shrink)
The associationist interpretation of Hume's account of causal belief is criticized. The origin of this mistaken interpretation is explained. The difference between Hume's views in the Treatise of Human Nature and in An Enquiry concerning Human Understanding is examined.
Robert Jervis's System Effects was published just as systems thinking began to decline among political scientists, who were adopting increasingly strict standards of causal identification, privileging experimental and large-N studies. Many politically consequential system effects are not amenable to research designs that meet these standards, yet they must nonetheless be studied if the most important questions of international politics are to be answered. For example, if nuclear weapons are considered in light of their effect on the international system as a (...) whole, it becomes clear that they have obviated the need for a global balance of power by allowing states to counterbalance threats by acquiring nuclear weapons rather than investing in massive conventional balancing efforts. Similarly, systems thinking should inform our understanding of the impact of a ?unipolar power? such as the United States, which has enjoyed an overwhelming preponderance of conventional military power since the fall of the Berlin Wall. A unipolar power is likely to become involved in frequent conflicts because it is not restrained by the presence of a peer competitor. (shrink)
Hume's project aimed at the discovery of the principles of human nature, and among these the most important in most respects is not association of ideas, but the one he calls "custom or habit." But what is the real nature of Hume's principle? It would be philosophically naïve to decide that Hume's concept of habit simply reproduces the dominant conception. In the latter the main element is time, and the possibility of habit depending only on repetition is absent in the (...) tradition, from Aristotle to Berkeley. When Hume proposes to explain causal inference by habit, he uses this word as tantamount to the old principle of induction by simple enumeration, which may depend only on repetition, the element of time being reduced to the strict minimum necessary for the repetition to occur. Hume's principle of causal knowledge is really a new principle, not the old "psychological" tendency called custom or habit, and his attempt tacitly was to change the very essence of the concept involved.

Russell's The Problems of Philosophy tries to establish a new theory of induction, at the same time that Hume is there accused of an irrational/ scepticism about induction". But a careful analysis of the theory of knowledge explicitly acknowledged by Hume reveals that, contrary to the standard interpretation in the XXth century, possibly influenced by Russell, Hume deals exclusively with causal inference, never with inductive inference in general, mainly generalizations about sensible qualities of objects. Russell's theories are thus only false (...) alternatives to Hume's, in or in his. (shrink)
Este artigo é parte do projeto de pesquisa "Formação médica na construção de competência e cidadania'', que se propõe averiguar em que medida as demandas exigidas pelas transformações macro sociais em relação à instauração de competências estão sendo incorporadas pelo processo de formação desenvolvido na Faculdade de Medicina da PUCRS, contribuindo para o fortalecimento da cidadania.
In this paper we suggest a model of sequential auctions with endogenous participation where each bidder conjectures about the number of participants at each round. Then, after learning his value, each bidder decides whether or not to participate in the auction. In the calculation of his expected value, each bidder uses his conjectures about the number of participants for each possible subgroup. In equilibrium, the conjectured probability is compatible with the probability of staying in the auction. In our model, players (...) face participation costs, bidders may buy as many objects as they wish and they are allowed to drop out at any round. Bidders can drop out at any time, but they cannot come back to the auction. In particular we can determine the number of participants and expected prices in equilibrium. We show that for any bidding strategy, there exists such a probability of staying in the auction. For the case of stochastically independent objects, we show that in equilibrium every bidder who decides to continue submits a bid that is equal to his value at each round. When objects are stochastically identical, we are able to show that expected prices are decreasing. (shrink)
Radical skepticism, irrationalism, psychologism, and epistemological despair are popular interpretations of Hume. The theory of causal inference has been supposed to stand at the very heart of Humean skepticism, mainly because of its ‘associationism’. However, the myth of a skeptical Hume—more radical than he really is in his own admitted ‘mitigated skepticism’—has been discredited in recent years. Hume certainly was an associationist about the passions, and moral sentiments, and the rules of justice in society, and many other aspects of human (...) life, as different as literary taste and superstition. There is plenty of evidence of this in Books II and III of the Treatise, in the second Enquiry, in the Dissertation on the Passions and in the Essays. But my main point here is that association of ideas has no cognitive role in his philosophy, beyond serving as “the cement of complex ideas.” Custom or habit do have such a cognitive role, as is well known, and shall be discussed below.
