En esta ponencia nos proponemos mostrar que ciertas tesis o consensos recibidos sobre pseudoprocesos causales , procesos cuya característica prominente parece ser superar la velocidad de la luz, deben ser cuestionados o seriamente modificados. Dos de dichos consensos son, primero, que los PSP deberían ser tratados simplemente como "basura espacio-temporal" y, segundo, que ellos no cumplen, aparte de permitir aislar procesos causales genuinos, ninguna función epistémica o metodológica en la descripción de cualquier estado físico, en particular, al interior de la (...) relatividad especial . Para ello, apelaremos a procedimientos de medición física bien conocidos tanto en física clásica como en RE. Como consecuencia de lo anterior, argumentamos que, una vez que los PSP son integrados en toda la escena física, se revela que ellos juegan un rol fundamental y más complejo en la física experimental de lo que hasta ahora se ha pensado. In this paper we show that some received contentions about causal pseudo processes , processes of which the most salient aspect seems to be travelling faster than the speed of light, must be rejected o seriously modified. Two of such contentions are, first, that PSPs should be considered just "spatiotemporal junk" and, second, that they do not meet, besides allowing us to isolate proper genuine causal processes, any other epistemic or methodological role in the description of a physical state of affair, in particular, in a special relativity setting. In order to do that, we are going to appeal to physical measure procedures, well known both in classic and relativistic physics. As a consequence of that, we contend that, once PSPs are integrated into the whole physical scenario, a fundamental and more complex role for them in experimental physics is revealed. (shrink)

In this essay we show that some thesis -contended by some authors searching on physical causation- about causal pseudoprocesses, processes of which the most salient aspect seems to be travelling faster than the speed of light, must be rejected o seriously modified. Secondly, we will argue that there is just one non causal entities category and that special relativity does not provide any particular motivation to appeal to an ontological distinction based on identity over time. In addition, this conclusion we (...) will enable us to offer a more accurate definition of a pseudoprocess than that found in the relevant literature. In third place, we will show in some detail how such processes, understood the way that we suggest here, are and have been valuable methodological tools when studying –through usual measurement procedures- effective causal relations holding in the physical world. Finally, we will connect our conclusions with R. Torretti’s criticism on the relation between ordinary causation and governed-by-differential-equations physical processes and we will show that, although neutral on his anthropocentric background, the account here argued provides, against what Torretti claims, a natural explanation to the physical connection between ordinary causation and causal processes such as studied by physics.

During the 24 years of the Indonesian occupation of East Timor, to talk about its cultural individuality as a product of its history - focusing on what set it apart from Indonesia - was an act likely to raise suspicions of some kind of manipulation of history for political purposes. Naturally, the same suspicions could fall on anyone assuming an opposite view, that is a view that valued the connection uniting the two peoples and discarded what separated them. In this (...) paper, we adhere more to the first perspective. Obviously, we are not driven by the desire to prove that East Timor had to be, a priori, independent; this is by no means the task of a historian. We are simply trying to explain, a posteriori, why, in the referendum of 30 August 1999, the people of East Timor voted overwhelmingly for independence. (shrink)

Os sistemas de cômputo do tempo na Índia são extremamente complexos, devido a dois factores: em primeiro lugar a coexistência não só de diversas teorias e tabelas astronómicas mas também de diferentes calendários, que em parte resulta de a Índia raramente ao longo da sua história ter constituído uma unidade política; em segundo lugar uma grande preocupação, quiçá de origem mágica, com a objectividade astronómica dos dados utilizados no cômputo do tempo. Do primeiro factor indicado resultam, por exemplo, a coexistência (...) de calendários solares, predominantes em certas regiões, com calendários luni-solares nas restantes, a contagem dos meses a partir da lua-nova ou da lua-cheia, consoante as zonas, etc. Do segundo resultam por exemplo: a adopção de estranhas unidades de tempo, como o tithi (que se pode definir como a trigésima parte de uma lunação, ou, em outros termos, o tempo que, após uma conjunção com o Sol ou seja uma lua-nova, a Lua demora a afastar-se deste 12° sobre o zodíaco); a entrada em conta da precessão dos equinócios para efeitos de determinação do início dos signos do zodíaco; etc. O presente artigo procura resumir e explicar essa diversidade de uma perspectiva histórica, pondo-a em relação com a evolução da astronomia indiana.

This article sets out to explore the socio-linguistic situation of Goa, a small territory corresponding to the former district of Goa of the Portuguese Estado da Índia, occupied and annexed by India in 1961. Goa had to choose between local language, Konkani, and the language of the neighbouring state of Maharashtra, i. e., Marathi, which was traditionally used as a cultural language by the Hindus of Goa, who nowadays form the large majority of the population. Even if virtually every Goan (...) is able to speak Konkani, this was, according to recent statistics, the mother tongue of only 61 % of the population of the state, the rest being forms by people from other parts of India, who migrated here. This phenomenon explains the feeble proportion of Konkani speakers in the total population of the state, which favours the resort to English as a means of communication and explains why Konkani only keeps an elevated status in churches, where it is currently used for praying and preaching. Drawing upon historical facts, but also on socio-linguistic consideration, we will try to explain this paradox. (shrink)

L'A. de cette étude analyse des textes inédits d'Hilaire de Poitiers où ce dernier parle de la réciprocité des relations trinitaires et de la mutuelle «interdépendance» du Père et du Fils. Il montre que l'insistance sur les relations originaires et sur les processions divines ne signifient pas nécessairement l'infériorité du Fils, et que si celui-ci n'existe qu'en totale référence au Père, de même ce dernier se réfère au Fils et ne peut exister sans lui.

The trinitarian theology of Karl Rahner has been the object of much discussion that has concentrated above all on two points: the «fundamental axiom» of the trinitarian theology and the problems surrounding the concept ofthe divine person. The fundamental axiom has helped to reclaim the central place of the mystery of the Trinity in the Christian faith and the need to set out from the economy of salvation as the only way to search more deeply into the mystery of God. (...) If the first part of the axiom, «the economic Trinity is the immanent Trinity», has been commonly accepted, the second, «and vice versa», has been the object of criticism. It must be emphasized in each case that the economy of salvation does not constitute or perfect the triune God and that He acts in it with full freedom. With these provisos, the second part of the axiom becomes not only legitimate but necessary to guarantee the universal mediation of Christ in whom God has reconciled the world to Himself. The concrete development of the trinitarian theology of Karl Rahner is not without its problems. It has been accused of tending toward modalism, in that the «personal» character of the divine hypostases in the immanent Trinity is much diminished. The article reviews the criticisms of various types that have been made and tries to offer a balanced interpretation of the thought of the German theologian that bears in mind its various aspects.

Célebre pintor do século XVIII, Joshua Reynolds apresentou ao longo dos anos 1769-1790 discursos para Royal Academy of Arts. Neles, expõe uma concepção de pintura que privilegia os quadros históricos. No entanto, o próprio Reynolds pratica a pintura de retratos. Analisar em que medida a feitura de retratos não entra em contradição com o argumento segundo o qual os quadros históricos são aqueles que melhor representam o gênero pictórico é o que se busca problematizar neste texto.

In the following pages, the main proposal is to indicate how Max Weber has dialogued directly with some prerogatives from Kant’s Critic of practical Reason, following the reception of Wilhelm Windelband’s concept of “responsibility” (Verantwortlichkeit) and his theory of values. In sight of these influences, in this paper will be argued how Weber adherence to the neo-Kantian value concept has made possible a review on the categorical imperatives, which has turned his reading from Kantian philosophy to the proposal of an (...) antinomy between the ethic of conviction and the ethic of responsibility inside the Kantian moral maxims. -/- Nessa abordagem será proposto que a recepção de Max Weber do conceito de “responsabilidade” (Verantwortlichkeit) de Wilhelm Windelband, bem como sua revisão de certos elementos da filosofia dos valores neokantiana do sudoeste da Alemanha, permitiram que Weber estabelecesse um diálogo mais direto com os pressupostos de Kant em sua Crítica da razão prática. Em vista dessas influências, o presente artigo argumentará que a maneira como Weber revisa os imperativos categóricos direcionou sua compreensão da filosofia kantiana pelo conceito de “valores”, o permitindo ainda, propor a existência de uma antinomia entre a ética da convicção e da responsabilidade no interior das máximas morais kantianas.

Voltaire has presented in his Letters on the English different themes, from religious ethics, literacy, politics, to dramas and science. The letters present us a comparison between England and France. In this parallel we shall present how Voltaire was concerned in evaluate a high standard of taste and refinements. This paper will review some of the last letters of those, which testify about this criterion of taste as a modern point of view. We shall present in Voltaire the eminence of (...) modernity in taste, refinements and on liberty of enjoying the ecstasies of a cosmopolitan life fulfilled with entertainments and luxury. We shall present how Voltaire fought against barbarism in benefit of civilization and some how against religiosity in benefit of an ethic hedonism. (shrink)

The tragic death in Tolstoy's writings has helped both Max Weber and György Lukács in characterizing the modern pathos as a tragic contemplation of the emptiness of life. Through Tolstoy's readings, Weber and Lukács found an interesting source of denying arts and modern sciences autonomy, considering, from the aesthetics sphere, the meaningless of this new immanent reality. Both has assumed Tolstoy main theme from the same perspective, contrasting ancient and modern worldviews. Max Weber presented this theme in his disenchantment of (...) world theory and Lukács, in a very similar way, following the paradox of religious needing as a mainline. -/- O tema da morte trágica, presente nos escritos de Liev Tolstói, auxiliou tanto a Max Weber como a György Lukács a caracterizarem o pathos moderno de pressentimento da morte como uma contemplação do vazio. Weber e Lukács encontraram, através das leituras de Tolstói, uma interessante maneira de questionar a autonomia da arte e da ciência moderna, considerando pela esfera estética, como se mostra sem sentido a recente realidade imanente. Ambos assumiram o tema central das obras de Tolstói segundo uma mesma imagem, derivada do contraste entre o mundo antigo e o moderno. Max Weber adequou esse tema a sua teoria do desencantamento do mundo e Lukács, de modo muito semelhante, seguindo seu conceito do paradoxo da necessidade religiosa. (shrink)

In this paper we study the axiomatic system proposed by Bourbaki for the Theory of Sets in the Éléments de Mathématique. We begin by examining the role played by the sign \(\uptau \) in the framework of its formal logical theory and then we show that the system of axioms for set theory is equivalent to Zermelo–Fraenkel system with the axiom of choice but without the axiom of foundation. Moreover, we study Grothendieck’s proposal of adding to Bourbaki’s system the axiom (...) of universes for the purpose of considering the theory of categories. In this regard, we make some historical and epistemological remarks that could explain the conservative attitude of the Group. (shrink)

We examine the extent to which host country income inequality influences multinational enterprises’ (MNE) expansion strategy for foreign production investment, depending on their specific strategic objectives. Applying a transaction cost framework, we predict that national income inequality has an inverted U-shaped relationship with foreign production investment. As inequality increases, MNEs accrue lower transaction costs arising from interactions with various local actors, leading to higher probability of investment. As income inequality increases further, its effect on location attractiveness will become negative, as (...) its attraction effect is increasingly offset by additional monitoring, bargaining, and security costs owing to the more fractious nature of high inequality societies. In addition, we suggest that the impact of income inequality is contingent on investment objectives: The inverted U-shaped relationship is stronger for efficiency-seeking investment but weaker for market-seeking and competence-enhancing investments. We find substantial support for our hypotheses through an analysis of 27 years (1986-2012) of data on Japanese MNEs’ overseas production entries. (shrink)

Referindo-se ao capítulo 6 da minha Introduction to Logical Theory, o professor Calabria demonstra de modo correto e sistemático que, tal como exposta, a doutrina da pressuposição implica uma concepção da lógica que é substancialmente desviante tanto no que diz respeito à lógica tradicional como à lógica moderna clássica.

The quantization of the magnetic flux in superconducting rings is studied in the frame of a topological model of electromagnetism that gives a topological formulation of electric charge quantization. It turns out that the model also embodies a topological mechanism for the quantization of the magnetic flux with the same relation between the fundamental units of magnetic charge and flux as there is between the Dirac monopole and the fluxoid.

We present here the hypothesis that the unique microenvironmental pH landscape of acid‐base transporting epithelia is an important factor in development of epithelial cancers, by rendering the epithelial and stromal cells pre‐adapted to the heterogeneous extracellular pH (pHe) in the tumor microenvironment. Cells residing in organs with net acid‐base transporting epithelia such as the pancreatic ductal and gastric epithelia are exposed to very different, temporally highly variable pHe values apically and basolaterally. This translates into spatially and temporally non‐uniform intracellular pH (...) (pHi) patterns. Disturbed pHe‐ and pHi‐homeostasis contributes to essentially all hallmarks of cancer. Our hypothesis, that the physiological pHe microenvironment in acid‐base secreting epithelia shapes cancers arising in these tissues, can be tested using novel imaging tools. The acidic tumor pHe in turn might be exploited therapeutically. Pancreatic cancers are used as our prime example, but we propose that this concept is also relevant for other cancers of acid‐base transporting epithelia. (shrink)

This article analyzes the relation of the epistemological beliefs of students and teachers and the actions deployed in the classroom. The framework is the study of personal epistemology, which was developed, among other researchers, by Hofer, Pintrich and Schommer. The research method was, within the qualitative paradigm, through case studies, given the interest in describing the phenomenon in a specific scenario. The results show the epistemological beliefs of teachers and students, the events that make them evident and its relationship with (...) the behaviors shown in the classroom. The role of pedagogical beliefs as mediation between personal epistemology of educational actors and their practice are described and, finally, the relation between beliefs and educational practice is illustrated by analyzing specific class events and the justification expressed by teachers and students about their actions in the classroom.

In this contribution, we use the connection between stable polynomials and orthogonal polynomials on the real line to construct sequences of Hurwitz polynomials that are robustly stable in terms of several uncertain parameters. These sequences are constructed by using properties of orthogonal polynomials, such as the well-known three-term recurrence relation, as well as by considering linear combinations of two orthogonal polynomials with consecutive degree. Some examples are presented.
