Los autores se preguntan por el aporte real de los biocombustibles a la solución de los problemas ambientales. Después de analizar las actuales formas de producción en Brasil, sostienen que la expansión de éstos presionará indirectamente hacia la deforestación, contribuyendo así aún más al calentamiento global. Señalan lo falaz del discurso que justifica la expansión de los biocombustibles por su aporte a la generación de empleo. Sostienen que es fundamental incorporar los requerimentos de sostenibilidad en la cadena de producción para (...) garantizar competitividad a los países potencialmente exportadores, pero que aún así esa solución es limitada ya que todas las energías alternativas y renovables juntas, no suplirían las proyecciones del patrón de consumo mundial.

BackgroundPreprint usage is growing rapidly in the life sciences; however, questions remain on the relative quality of preprints when compared to published articles. An objective dimension of quality that is readily measurable is completeness of reporting, as transparency can improve the reader’s ability to independently interpret data and reproduce findings.MethodsIn this observational study, we initially compared independent samples of articles published in bioRxiv and in PubMed-indexed journals in 2016 using a quality of reporting questionnaire. After that, we performed paired comparisons (...) between preprints from bioRxiv to their own peer-reviewed versions in journals.ResultsPeer-reviewed articles had, on average, higher quality of reporting than preprints, although the difference was small, with absolute differences of 5.0% [95% CI 1.4, 8.6] and 4.7% [95% CI 2.4, 7.0] of reported items in the independent samples and paired sample comparison, respectively. There were larger differences favoring peer-reviewed articles in subjective ratings of how clearly titles and abstracts presented the main findings and how easy it was to locate relevant reporting information. Changes in reporting from preprints to peer-reviewed versions did not correlate with the impact factor of the publication venue or with the time lag from bioRxiv to journal publication.ConclusionsOur results suggest that, on average, publication in a peer-reviewed journal is associated with improvement in quality of reporting. They also show that quality of reporting in preprints in the life sciences is within a similar range as that of peer-reviewed articles, albeit slightly lower on average, supporting the idea that preprints should be considered valid scientific contributions.

Given its non-invasive nature, there is increasing interest in the use of transcutaneous vagus nerve stimulation across basic, translational and clinical research. Contemporaneously, tVNS can be achieved by stimulating either the auricular branch or the cervical bundle of the vagus nerve, referred to as transcutaneous auricular vagus nerve stimulation and transcutaneous cervical VNS, respectively. In order to advance the field in a systematic manner, studies using these technologies need to adequately report sufficient methodological detail to enable comparison of results between (...) studies, replication of studies, as well as enhancing study participant safety. We systematically reviewed the existing tVNS literature to evaluate current reporting practices. Based on this review, and consensus among participating authors, we propose a set of minimal reporting items to guide future tVNS studies. The suggested items address specific technical aspects of the device and stimulation parameters. We also cover general recommendations including inclusion and exclusion criteria for participants, outcome parameters and the detailed reporting of side effects. Furthermore, we review strategies used to identify the optimal stimulation parameters for a given research setting and summarize ongoing developments in animal research with potential implications for the application of tVNS in humans. Finally, we discuss the potential of tVNS in future research as well as the associated challenges across several disciplines in research and clinical practice. (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)

La posmodernidad es una tendencia emergente a lo largo del siglo XX, un proceso general de la cultura occidental que fue aglutinando síntomas contrapuestos, y que acabó por dominar la escena filosófico-cultural a medida que avanzaba el siglo.

The progress of Mathematics during the nineteenth century was characterised both by an enormous acquisition of new knowledge and by the attempts to introduce rigour in reasoning patterns and mathematical writing. Cauchy’s presentation of Mathematical Analysis was not immediately accepted, and many writers, though aware of that new style, did not use it in their own mathematical production. This paper is devoted to an episode of this sort that took place in Spain during the first half of the century: It (...) deals with the presentation of a method for numerically solving algebraic equations by José Mariano Vallejo, a late Spanish follower of the Enlightenment ideas, politician, writer, and mathematician who published it in the fourth (1840) edition of his book Compendio de Matemáticas Puras y Mistas, claiming to have discovered it on his own. Vallejo’s main achievement was to write down the whole procedure in a very careful way taking into account the different types of roots, although he paid little attention to questions such as convergence checks and the fulfilment of the hypotheses of Rolle’s Theorem. For sure this lack of mathematical care prevented Vallejo to occupy a place among the forerunners of Computational Algebra. (shrink)

Existe-t-il véritablement, du point de vue cognitif et épistémologique, une distance insurmontable entre grandes et petites mythologies, entre les récits fondateurs sur lesquels reposent nos références culturelles et littéraires et toutes ces métaphores qui façonnent et orientent en profondeur nos expressions langagières et les objets qui nous entourent et qui, elles aussi, racontent une histoire? Si aucune société ne peut vivre sans mythes, nul ne saurait vivre ni signifier sans métaphore. Et si Œdipe ou Philoctète sont des signifiants lourds de (...) sens capables de générer une pléiade de configurations poétiques sans cesse renouvelées, Levi’s, Coca-Cola ou Apple ne sont pas moins, bien qu’à une dimension et à un degré différent, des noms qui se sont progressivement érigés au statut de mythes contemporains grâce à une habile stratégie où image et récit fondateur se renforcent et se légitiment réciproquement. En tant que force qui harmonise l’ordre et le désordre, le chaos et le cosmos, la symétrie et la dissymétrie, la Loi et la dimension de la fête et du jeu, Apollon et Dionysos, la vie intérieure et l’expérience du monde ; bref, en tant que principe médiateur et réunificateur de l’univers, de la forme et du sens, la métaphore est ainsi l’un des noms possibles de l’imaginaire. L’autre nom, c’est évidemment l’Amour. En effet, du Moyen Âge à l’époque contemporaine, l’amour, en tant que construction à partir d’une image-écran médiatrice, est toujours une quête du sens, un acte de signification, c’est-à-dire un processus dynamique mettant en relation les éléments disjoints du monde et de notre expérience. From a cognitive and epistemological perspective, does an insurmountable distance really exist between big and small mythologies, between founding narratives on which our cultural and literary references are based, all of the metaphors that fashion and orient the depth of our linguistic expression, and the objects that surround us, which, in their own way, tell a story? A society cannot live without myths; nor would one know how to live or to signify without metaphors. If Oedipus or Philoctetus are heavily loaded with meaning and capable of generating a constellation of constantly renewing poetic configurations, Levi’s, Coca-Cola or Apple do no less. Despite being at a different dimension and degree, these names have been progressively built up to the status of contemporary myths by way of a clever strategy in which image and founding story provide reciprocal reinforcement and legitimization. As a harmonizing force of order and disorder, of chaos and cosmos, of symmetry and asymmetry, of the Law and the dimension of party and play, of Apollo and Dionysus, of interior life and the experience of the world, in short, as a mediating and reunifying principle of the universe, of form, and of meaning, metaphor is one possible name for the imaginary. Its other name is, obviously, Love. In fact, from the Middle Ages to contemporary times, love, as a construction growing forth from a mediating image-screen, has always been a quest for meaning, an act of signification, a dynamic process connecting the fractal elements of our world and of our experience.

Desde Platón el arte ha sido deslegitimado filosóficamente porque su elemento y su medio es la apariencia. De tal manera que, el ser y la verdad, según la antigua teoría, se encuentran en las ideas y no en las apariencias sensibles. Hegel está lejos de este platonismo en sus Lecciones sobre estética y, por el contrario, va a realizar una reivindicación de la apariencia en el arte. El interés de este artículo es indagar por la distinción entre apariencia que engaña, (...) vinculada al no–ser, y la apariencia necesaria de las obras de arte que, para Hegel, es la apariencia de la esencia. El artículo aprovecha tanto la oposición planteada por Hegel entre belleza natural–belleza espiritual, como el modo de ser del arte como ideal, para indicar que es la apariencia del arte una de las formas donde el espíritu se hace concreción, donde revela su conciencia activa, pensante, y puede manifestar sensiblemente las determinaciones e intereses más altos para su cultura.

El presente texto es un primer acercamiento a la tensión entre las necesidades y preferencias, a partir de dos pensadores significativos para la Teoría Crítica. Herbert Marcuse, miembro de la primera generación de la Escuela de Frankfurt, y Franz Hinkelammert, referente de una renovada Teoría Crítica nacida y continuada creativamente en América Latina. Pensadores que darán elementos esclarecedores para profundizar una problemática que nos preocupa hace tiempo: la cooptación de los deseos y su metamorfosis en necesidades como mecanismo de dominación (...) que opera, no ya en la conciencia sino en la misma sensibilidad humana.

Die Nietzscheforschung der letzten Jahrzehnte hat ein besonders Augenmerk auf den Einfluß gerichtet, den Kant auf Nietzsches Philosophie ausgreübt hat, inbesondere auf seine Wissenschafts- und erkenntnis-Kritik. Die Revision des Wahrheitsbegriffs seitens Nietzsches kommt so ans Tageslicht. Forscher wie J. Simon und F. Kaulbach haben unterstrichen, daß Nietzsche die schon von Kant angelegte Übertragung der Wahrheit aus dem Theoretischen ins Praktische vollzogen hat. In seiner geplanten Doktorarbeit im Jahr 1868 Die Teologie seit Kant greift Nietzsche F.A. Langes und K. Fischers Auslegungen (...) auf, deren Einfluß auch in seinen späteren Werken noch wahrnehmbar ist. Insbesondere entnimmt er Kant die Gegenüberstellung von menschlicher und tierischer Welt, der dann seine offene Kritik am kantischen "Anthropomorphismus" folgt. Nietzsche nimmt so mit Kant Stellung.In the last decades, many Nietzsche scholars have begun to attend Kant's influence on Nietzsche's philosophy, particularly on his criticism of science and of knowledge. This is how Nietzsche's reexamination of the concept of truth emerges. Scholars such as J. Simon and F. Kaulbach have stressed how Nietzsche has completed the displacement of truth - already formulated by Kant - from the level of theoretical reflection to the level of pragmatical reflection. In the planned Doktorarbeit of 1868, Die Teleologie seit Kant, Neitzsche uses Kant interpretations of F. A. Lange and K. Fischer, whose influence can still be found in the works of the maturity. It is mainly from Kant that Nietzche derives the opposition between human world and animal world. Such an opposition turns into an open criticism of what he considers the Kantian anthropomorphism. Thus, Nietzsche's position can be summarised as a movement mit Kant gegen Kant. (shrink)

O pensamento filosófico hispânico na segunda metade do séc. XX, potenciou um processo de emancipação cultural e filosófica mais profundas, que destacaram o sentido e o alcance de uma utêntica filosofia, no continente sul-americano. Com tomada de consciência da circunstância americana o que está em causa, é a procura e busca de uma autenticidade da razão latino-americana, a qual na análise que desenvolvo, só terá sentido se integrada numa dinâmica de integração cultural. Esta deverá sempre partir das circunstâncias próprias, e (...) desenvolvida a partir do respeito por um ethos vivencial comum. O presente estudo foi inspirado na obra de Carlos Beorlegui, intitulada Historia del pensamiento filosófico latinoamericano (2004), obra esta que nos apresenta uma visão geral da Filosofia latino-americana desde as cosmovisões pré-colombianas até às correntes filosóficas mais actuais, como é o caso da FL (Filosofia da Libertação), e a da pós-Modernidade ou pós-Colonialidade, comummente conhecida como interculturalismo.

Standardly, the usual approach to rationality is based on the notion of ‘being a reason for’. Honouring the traditional distinction between practical and theoretical philosophy, reasons are classified as justificative and explicative. In both cases, a reason-statement has the form ‘’. For reasons of type , ‘A’ is a factual statement and ‘B’ is a statement which describes an action of the agent. The reason-statement has a prescriptive sense because ‘A is a reason for doing B’ means ‘A is a (...) reason an agent ought to do B’. So, it is advisable to schematize that kind of statements as ‘’, where ‘OB’ is a deontic statement prescribing the duty to do B. Reasons of type have a descriptive sense and do not require the above-mentioned constraint. But ‘being a reason for’ has different senses according to context, even when the distinction between justificative and explicative reasons is drawn. Accordingly, it is important to distinguish two basic types of reasons: sufficient and necessary, and two subordinate types of reasons: contributing and substitutive . A lot of attention has been paid, lately, to a sense of contributive reasons: prima facie reasons . The paper will deal with that kind of reasons. Its main thesis are: 1) prima facie reason-statements are defeasible conditionals ‘’ pointing out that A is a contributing condition of B, 2) a defeasible conditional has the properties of ‘’, where ‘ =>’ is a strict implication and ‘f’’ a revision-operator satisfying the conditions set up by the theory AGM on the rational change of theories.
