A previous work by Friedman et al. (Theory and Decision, 61:305–318, 2006) introduces the concept of a hierarchy of a simple voting game and characterizes which hierarchies, induced by the desirability relation, are achievable in linear games. In this paper, we consider the problem of determining all hierarchies, conserving the ordinal equivalence between the Shapley–Shubik and the Penrose–Banzhaf–Coleman power indices, achievable in simple games. It is proved that only four hierarchies are non-achievable in simple games. Moreover, it is also proved (...) that all achievable hierarchies are already obtainable in the class of weakly linear games. Our results prove that given an arbitrary complete pre-ordering defined on a finite set with more than five elements, it is possible to construct a simple game such that the pre-ordering induced by the Shapley–Shubik and the Penrose–Banzhaf–Coleman power indices coincides with the given pre-ordering.

A number of citation indices have been proposed for measuring and ranking the research publication records of scholars. Some of the best known indices, such as those proposed by Hirsch and Woeginger, are designed to reward most highly those records that strike some balance between productivity (number of papers published) and impact (frequency with which those papers are cited). A large number of rarely cited publications will not score well, nor will a very small number of heavily cited papers. We (...) discuss three new citation indices, one of which was independently proposed in Fenner et al. (PLOS ONE 13(7): e0200098, 2018). Each rests on the notion of scale invariance, fundamental to John Nash’s solution of the two-person bargaining problem. Our main focus is on one of these—a scale-invariant version of the Hirsch index. We argue that it has advantages over the original; it produces fairer rankings within subdisciplines, is more decisive (discriminates more finely, yielding fewer ties) and more dynamic (growing over time via more frequent, smaller increments), and exhibits enhanced centrality and tail balancedness. Simulations suggest that scale invariance improves robustness under Poisson noise, with increased decisiveness having no cost in terms of the number of “accidental” reversals, wherein random irregularities cause researcher A to receive a lower index value than B, although A’s productivity and impact are both slightly higher than B’s. Moreover, we provide an axiomatic characterization of the scale-invariant Hirsch index, via axioms that bear a close relationship, in discrete analogue, to those used by Nash (Econometrica 18(2):155–162, 1950). This argues for the mathematical naturality of the new index. (shrink)

El tango es la música más evocativa del área del Río de la Plata. Mucho se ha dicho y escrito sobre este género que conquistó multitudes en varios contextos históricos y en diferentes lugares del mundo, pero existe un problema de visibilidad. En sus inicios y posterior desarrollo hay un aporte que se ha silenciado, el de la africanía, en línea con el blanqueo y el discurso histórico en Argentina que ha convertido al colectivo africano y afrodescendiente en el “primer (...) desaparecido”, un discurso que se repite hasta el hartazgo desde el sentido común y con el que resulta complicado lidiar. Si la música es una importante generadora de identidades, es necesario no perder de vista la participación y la impronta afro en el género arquetípico que define la argentinidad, y es característico de la región rioplatense, puesto que hace a la definición de un marco multicultural en donde la huella africana, entre otras, define el ser argentino y, en general, su impronta es fuerte en el área del Río de la Plata. Según estimaciones y pruebas pilotos, se estiman dos millones de afrodescendientes en Argentina y el último Censo indicó casi 150.000 auto-reconocidos/as a sí mismos/as, por primera vez en la historia nacional. Palabras clave: tango, identidad, música, Argentina, afrodescendencia. (shrink)

ArgumentIn this paper I follow the demise of the ether in the first half of the twentieth century to show how the first obituaries of the ether were instrumental in creating an object with specific and largely simplified properties related to, but different from, nineteenth-century ethers. I suggest that writing the history of dead objects (or objects an author wants to be dead) is not epistemologically neutral but, on the contrary, it involves a reformulation of the object itself. I show (...) that this was indeed the case with the ether: those arguing for its demise in the early twentieth century tended to overlook as irrelevant one of the ether’s most important properties, namely being the seat for the transmission of electromagnetic waves. Instead, they emphasized the contradictions between other properties of previous ether(s), so as to advocate for its disappearance. (shrink)

Based on narrative, iconographical, and liturgical sources, this is the first systematic study to trace the story of the ritual of royal self-coronations from Ancient Persia to the present. Exposing as myth the idea that Napoleon's act of self-coronation in 1804 was the first extraordinary event to break the secular tradition of kings being crowned by bishops, Jaume Aurell vividly demonstrates that self-coronations were not as transgressive or unconventional as has been imagined. Drawing on numerous examples of royal self-coronations, (...) with a particular focus on European Kings of the Middle Ages, including Frederic II of Germany, Alphonse XI of Castile, Peter IV of Aragon and Charles III of Navarra, Aurell draws on history, anthropology, ritual studies, liturgy and art history to explore royal self-coronations as privileged sites at which the frontiers and limits between the temporal and spiritual, politics and religion, tradition and innovation are encountered.

This paper has a twofold scope. The first one is to clarify and put in evidence the isomorphic character of two theories developed in quite different fields: on one side, threshold logic, on the other side, simple games. One of the main purposes in both theories is to determine when a simple game is representable as a weighted game, which allows a very compact and easily comprehensible representation. Deep results were found in threshold logic in the sixties and seventies for (...) this problem. However, game theory has taken the lead and some new results have been obtained for the problem in the past two decades. The second and main goal of this paper is to provide some new results on this problem and propose several open questions and conjectures for future research. The results we obtain depend on two significant parameters of the game: the number of types of equivalent players and the number of types of shift-minimal winning coalitions. (shrink)

Marcel Proust ha passat a la història de la cultura occidental com un escriptor, principalment novelista. Amb tot, la seva obra mestra. A la recerca del temps perdut, un dels cims de la literatura mundial, conté nombroses reflexions que permeten identificar clarament també un Proust pensador. Reconstruir la filosofia de Proust tot resseguint la mirada sobre el món que representa a la recerca?. és l'objectiu d'aquest assaig. A partir dels aforismes, sovint metafòrics, del Narrador proustià, Jaume Urgell ens ofereix (...) una anàlisi de la posició de l'escriptor francès en el context de la filosofia del segle XX. Expressant-se de vegades com a hereu d'un pensament anti-racionalista, en ocasions com a a coetani del existencialisme europeu i sovint precursor tant del pensament ironista com de mites de la quotidianitat més contemporània, Marcel Proust ens llega una obra plena de significats i alhora lliure de qualsevol convencionalisme, cosncient de les seves pròpies màscares i alhora innocent en el seu desenvolupament. Aquest assaigpresenta també algunes de les contribucions més rellevants en l'estudi de l'obra proustiana, com són les de Samuel Beckett, Gilles Deleuze i Richard Rorty, i desbrossa les incursions de Proust en el camp de la psicologia, l'ètica i l'estètica. Jaume Urgell És llicenciat en ciències empresarials i MBA per ESADE i Màster en Administració Pública per la Universitat de Harvard. Té un Diploma d'Estudis Avançats en Filosofia i Literatura per la UB.

Many American readers like to regard Alexis de Tocqueville as an honorary American and democrat--as the young French aristocrat who came to early America and, enthralled by what he saw, proceeded to write an American book explaining democratic America to itself. Yet, as Lucien Jaume argues in this acclaimed intellectual biography, Democracy in America is best understood as a French book, written primarily for the French, and overwhelmingly concerned with France. "America," Jaume says, "was merely a pretext for (...) studying modern society and the woes of France." For Tocqueville, in short, America was a mirror for France, a way for Tocqueville to write indirectly about his own society, to engage French thinkers and debates, and to come to terms with France's aristocratic legacy. By taking seriously the idea that Tocqueville's French context is essential for understanding Democracy in America, Jaume provides a powerful and surprising new interpretation of Tocqueville's book as well as a fresh intellectual and psychological portrait of the author. Situating Tocqueville in the context of the crisis of authority in postrevolutionary France, Jaume shows that Tocqueville was an ambivalent promoter of democracy, a man who tried to reconcile himself to the coming wave, but who was also nostalgic for the aristocratic world in which he was rooted--and who believed that it would be necessary to preserve aristocratic values in order to protect liberty under democracy. Indeed, Jaume argues that one of Tocqueville's most important and original ideas was to recognize that democracy posed the threat of a new and hidden form of despotism. (shrink)

Many bodies around the world make their decisions through voting systems in which voters have several options and the collective result also has several options. Many of these voting systems are anonymous, i.e., all voters have an identical role in voting. Anonymous simple voting games, a binary vote for voters and a binary collective decision, can be represented by an easy weighted game, i.e., by means of a quota and an identical weight for the voters. Widely used voting systems of (...) this type are the majority and the unanimity decision rules. In this article, we analyze the case in which voters have two or more voting options and the collective result of the vote has also two or more options. We prove that anonymity implies being representable through a weighted game if and only if the voting options for voters are binary. As a consequence of this result, several significant enumerations are obtained. (shrink)

RESUMENEl presente artículo analiza las diferentes teorías que sobre el concepto de función se han vertido en los últimos cuarenta años y sus problemas. Respecto de los dos grandes enfoques (histórico-etiológico y sistémico) se sostiene que el primero, pese a su hegemonía histórica, presenta considerables dificultades y que la reflexión actual se centra cada vez más en la perspectiva sistémica. Esta última puede enfrentarse mejor a los diversos problemas que genera el concepto de función biológica y es siempre preferible.PALABRAS CLAVEFUNCIÓN (...)

Concerning the two most important points of view on functions (aetiological theory and systemic theory) I hold that the aetiological theory, despite its historical hegemony, presents substantial difficulties and that the present philosophical thinking is centred on systemic theories. Systemic theories are capable of solving the various problems generated by the biological function concept which is preferable.KEYWORDSBIOLOGICAL FUNCTION, SySTEMIC FUNCTION, FUNCTIONAL EXPLANATION, MECHANISTIC EXPLANATION TELEOLOGY.

The origin of the bilaterian metazoans from radial ancestors is one of the biggest puzzles in animal evolution. A way to solve it is to identify the nature and main features of the last common ancestor of the bilaterians (LCB). Recent progress in molecular phylogeny has shown that many platyhelminth flatworms, regarded for a long time as basal bilaterians, now belong to the lophotrochozoan protostomates. In contrast, the LCB is now considered a complex organism bearing several features of modern bilaterians. (...) Here we discuss an alternative view, in which acoelomorph (Acoela + Nemertodermatida) flatworms, which do not belong to the Platyhelminthes, represent the earliest extant bilaterian clade. Sequences from ribosomal and other nuclear genes, Hox cluster genes, and reinterpretation of some morphological features strongly support the basal position of acoelomorphs arguing against a complex LCB. This reconstruction backs the old planuloid–acoeloid hypothesis and may help our understanding of the evolution of body axes, Hox genes and the Cambrian explosion.

Edmund T. Whittaker’s second edition of his A History of the Theories of Aether and Electricity is famous for his treatment of Einstein as an almost irrelevant character in the emergence of what he called “the relativity theory of Poincaré and Lorentz.” Historians of science have given a number of explanations, which include Whittaker’s scientific conservatism as an old classical physicist, his commitment to the ether, the pre-eminent role he attributed to mathematics over physics, and foundational philosophical disagreements, to name (...) a few. And in the background, often more implicit than forthright, the accusation of antisemitism looms over Whittaker. In this paper I intend to shed new light on this controversy by taking into consideration the abundant correspondence between Whittaker and his son preserved in the archives of the Fisher Library, University of Toronto. With it, we will get a more complex and personal view of the context in which his attempt at dethroning Einstein took place. Together with the abovementioned reasons, this correspondence shows that the problematic status quo of general relativity in the early 1950s, a period that has been described as the low-mark of general relativity, was very influential in the historical treatment he gave to Einstein. This is an aspect hardly mentioned in the historical work on this controversy and, from this correspondence, it appears to be central to understanding Whittaker at the time of drafting the new History. His possible antisemitic bias will also be addressed, though with the insufficient information on this subject the matter cannot be settled. (shrink)

Friedrich Nietzsche resorted several times to the image of a child playing with sand or pebbles. His purpose in doing so was to evoke a cyclical process of construction and destruction devoid of both responsibility and finality. This essay examines, on the one hand, the relation of the child’s image to its two main hypotexts (Heraclitus DK 22 B 52 and Iliad XV 362-64) and, on the other, the range of Nietzsche’s uses of the simile.

El presente artículo aborda el problema del escepticismo en Comenius y Descartes en sus relaciones con la teología natural. Ambos autores emplean la teología natural como modo de deshacerse de la amenaza escéptica. Si bien, el uso que hacen de la misma es muy distinto, llegándose a plantear dos concepciones de la filosofía muy diferentes. Comenius supedita la filosofía al mensaje revelado, mientras que Descartes independiza la filosofía respecto de la teología revelada. Pese a las coincidencias en la necesidad de (...) reformar el saber, hacer frente a la amenaza escéptica y emplear la teología natural en su lucha, son dos propuestas filosóficas coetaneas claramente diferentes.

Karl Popper always claimed himself to be a realist. However, his constant denial to give definitions to the philosophical concepts, makes it difficult to understand what exactly he means by realism. This article focuses the attention on three meanings of Popper’s realism: a metaphysical, an epistemological and a sensible realism. The later sense can be rooted in the new studies on the ethical roots of all Popper’s philosophy.

Trente ans après la fin définitive de la dictature et l'approbation de la Constitution de 1978, après trente-sept ans de franquisme, le moment semble venu pour l'Espagne moderne de revenir sur les années de dictature. L'ombre du franquisme n'avait jamais disparu, mais elle revient, puissante, avec l'opposition des partis de droite à la « Loi sur la mémoire historique » et le refus de l'Église de reconnaître une quelconque responsabilité dans les exactions du franquisme. La rencontre entre la Mémoire et (...) la Loi est au cœur de cet article.Thirty years alter dictatorship finally came to an end with the adoption of the 1978 Constitution and after thirty seven years of Francoism, the time seems to have come for modern Spain to look back on those years. The shadow of Francoism had never entirely disappeared, and it has returned, powerfully, with oppo­sition from the right-wing parties to the "Historical Memory Law" and the Church' s refusal to admit to any responsibility in the abuses of power meted out by the Franco regime. The encounter between Memory and Law is the core issue of this article. (shrink)

This article delves into the reception of John W. Draper's History of the Conflict between Religion and Science in Spain. With two translations into Spanish appearing almost simultaneously in 1876, the conflict became a weapon in a long political dispute. The tensions between conservatives and liberals, between monarchists and republicans had the university and pedagogical reforms as one of the main battlefields. One of the chief reformist movements was informed by “Krausism,” an ideology that had academic freedom as one if (...) its central tenets. The similarities between the educational agenda of Draper and that of Krausists explain why the former's book resonated among members of the latter group. The article argues that in order to understand the reception of Draper in Spain, one should pay attention to the disputes about national identity and educational reforms, so as to place the so‐called conflict thesis in the context of opposing Spanish patriotisms.

The memories of the teaching we had during the seventies at the Autonomous University of Barcelona show, forty years later, that this teaching was not a matter of a premeditated learning program. However, the diversity of the teachers we knew, their characters and examples, project a certain shadow of a philosophical experience that has been shared by several generations of contemporary Catalan philosophers.

Con Tocqueville la soberanía va a conocer un desplazamiento de lugar. En la articulación entre "estado social y "estado político", la soberanía toma formas inusitadas en la tradición de la teoría política y se convierte en la opinión democrática, la nueva "autoridad social". En Estados Unidos se da además en la vida local, forma de sociabilidad y poder en la que lo público y lo privado interactúan; porque la autoridad moderna y democrática del futuro ya no será propiedad y privilegio (...) del Estado, tal y como ocurría en la monarquía absoluta de las sociedades europeas.

Dans cet article, j’essaie de montrer la pertinence de la Phénoménologie de la perception pour répondre aux défis de la philosophie dans un monde à la fois déchirée et globalisateur. Si on laisse de côté la dimension théorétique du monde, nous recupérons le fond obscure de l’existence, fond de tous les espaces. Il s’agirait d’un espace primigène dans lequel on trouve le lien affectif propre de l’expérience des enfants et des primitives. Mais le vécu de ces espaces implique une perte (...) du espace de jeu qui fait possible le monde comme ouverture et intersubjectivité. La réponse de Merleau-Ponty devant le psychologisme suppose un tournant envers la philosophie traditionnelle parce qu´il réussit à garder près de sa conscience les consciences «autres» du schizophrène ou de l’enfant.
