Yablo's paradox and referring to infinite objects

The blame for the semantic and set-theoretic paradoxes is often placed on self-reference and circularity. Some years ago, Yablo [1985; 1993] challenged this diagnosis, by producing a paradox that's liar-like but does not seem to involve circularity. But is Yablo's paradox really non-circular? In a recent paper, Beall [2001] has suggested that there are no means available to refer to Yablo's paradox without invoking descriptions, and since Priest [1997] has shown that any such description is circular, Beall concludes that Yablo's paradox itself is circular. In this paper, we argue that Beall's conclusion is unwarranted, given that (1) descriptions are not the only way to refer to Yablo's paradox, and (ii) we have no reason to believe that because the description involves self-reference, the denotation of the description is also circular. As a result, for all that's been said so far, we have no reason to believe that Yablo's paradox is circular.

The application of wave induced forces to a two-dimensional finite element long wave hydrodynamic model

This paper describes the modification of a two-dimensional finite element long wave hydrodynamic model in order to predict the net current and water levels attributable to the influences of waves. Tests examine the effects of the application of wave induced forces, including comparisons to a physical experiment. An example of a real river system is presented with comparisons to measured data, which demonstrate the importance of simulating the combined effects of tides and waves upon hydrodynamic behavior.

Wall mediated transport in confined spaces: Exact theory for low density

We present a theory for the transport of molecules adsorbed in slit and cylindrical nanopores at low density, considering the axial momentum gain of molecules oscillating between diffuse wall reflections. Good agreement with molecular dynamics simulations is obtained over a wide range of pore sizes, including the regime of single-file diffusion where fluid-fluid interactions are shown to have a negligible effect on the collective transport coefficient. We show that dispersive fluid-wall interactions considerably attenuate transport compared to classical hard sphere theory.

Dimensional X: a dificuldade na obten????o da informa????o em meio a problemas na gest??o de pessoas

Ant??nio foi convidado para assumir um cargo em que deveria gerenciar os sistemas de informa????o de um grande minist??rio. Com a miss??o inicial de fornecer uma informa????o sobre a for??a de trabalho, percebeu que havia problemas que iam muito al??m da simples utiliza????o desses sistemas, como a pol??tica de capacita????o de pessoal, a rotatividade de servidores, a falta de integra????o entre as ??reas e outros problemas na ??rea de gest??o de pessoas

A manipulação do tópico discursivo como estratégia da preservação de face

Como em toda interação há o desejo de construir perante os outros uma imagem favorável de si próprio (Goffman, 1967), as entrevistas constituem-se em um espaço de confronto, já que é impossível controlar a imagem que um participante faz do outro. Sendo assim, neste trabalho, faz-se uma análise discursivo-pragmática de entrevistas impressas, tendo como base a noção de face, elaborada por Goffman (1967); a Teoria da Polidez, de Brown e Levinson (1987) e a noção de tópico discursivo como princípio de organização textual-discursiva, Koch (1992), Jubran (1992) e Lins (2008). Deste modo, focaliza-se o contexto de interação verbal em entrevistas a figuras do cenário político estadual/nacional realizadas pelo Jornal A Gazeta, publicadas nos anos de 2004, 2006 e 2008. Nas entrevistas, observa-se como acontecem os atos de ameaça às faces positiva e negativa na relação entrevistador-entrevistado, bem como quais estratégias de polidez eles utilizam para salvar e preservar as suas faces a partir do gerenciamento do tópico discursivo, tendo em vista que os atos de ameaça às faces positiva e negativa podem ser minimizados a partir de estratégias de manipulação do tópico. As principais questões que norteiam este estudo são: a necessidade de construção de face positiva é situação sine qua non para convivência social? É característico no gênero Entrevista a manipulação do tópico como estratégia de preservação de face? Quais estratégias de manipulação de tópico discursivo caracterizam a preservação de face? Dessa forma, esta pesquisa se põe relevante no interior das pesquisas sobre linguagem, uma vez que nela são tecidas reflexões sobre questões muito discutidas pela academia ultimamente, porém de forma separada: manipulação do tópico discursivo, no âmbito da Linguística Textual, e preservação de face, no âmbito da Pragmática.

Rio Branco, grand strategy and naval power

This article addresses Baron of Rio Branco's grand strategy and the role played by the naval reorganization program (1904-1910) in this context. The ensuing case study determined the domestic and international constraints that affected the program, as well as the worldview of the patron of Brazilian diplomacy regarding military power's instrumentality to foreign policy.

Swords into ploughshares? China's Soft Power strategy in Southeast Asia and its challenges1

Since the 1990s, alongside China's economic growth, the international community has fostered a general anxiety towards a "China threat." In order to relieve itself from suspicion, China adopted the dual strategies of "harmonious worldview" and "good neighbor policy." The strategies led to the use of soft power in China's foreign policy. China aimed to reduce security concerns implied by the threat theory by supporting an image that caters to international peace and development. This article seeks to explain how China achieves its interests in Southeast Asia through the use of soft power. The authors address the concepts of "harmonious worldview" and "good neighbor policy" and how the twin strategies and soft power have shaped China's foreign policy in recent years. This article aims to provide insights into China's policy options in Southeast Asia in the near future.

Critical behavior of a three-dimensional hardcore-cylinder composite system

In this work the critical indices β, γ , and ν for a three-dimensional (3D) hardcore cylinder composite system with short-range interaction have been obtained. In contrast to the 2D stick system and the 3D hardcore cylinder system, the determined critical exponents do not belong to the same universality class as the lattice percolation,although they obey the common hyperscaling relation for a 3D system. It is observed that the value of the correlation length exponent is compatible with the predictions of the mean field theory. It is also shown that, by using the Alexander-Orbach conjuncture, the relation between the conductivity and the correlation length critical exponents has a typical value for a 3D lattice system.

"Procedural Strategy" by Carlos Pinto de Abreu, lawyer

Como Carlos Pinto de Abreu refere e bem, no seu livro e no seminário, entre juízes, partes ou sujeitos processuais, advogados ou solicitadores, magistrados do Ministério Público ou testemunhas, peritos ou funcionários, encontramos “pessoas que podem ser mais ou menos sérias”, por sinal “motivadas por outros interesses que não os de servir a Verdade e a Justiça”; Abstract: Carlos Pinto de Abreu as regards and well in his book and seminar, between judges, parties or procedural subject, lawyers or solicitors, prosecutors and witnesses, experts or officials, found "people who may be more or less serious" , by the way "motivated by interests other than those serving the Truth and Justice".
