Resumen En este texto se intenta mostrar que la radicalización de la tesis expresada por Platón en el libro X de la República no permite "apreciar" el valor que el filósofo ateniense sabe que posee la poesía, pues ella podría ser un medio para el ejercicio reflexivo si se sirve de la sobriedad que la filosofía propone. Para realizar esta tarea es menester trazar tres puntos sobre los cuales gira este texto: primero, se ubica al lector en la discusión entre (...) poesía y filosofía para comprender el contexto de la crisis entre estos dos factores de la educación en la antigüedad griega; segundo, se aborda la crítica establecida en el libro X sobre la falta de rigor que muestran los poetas en la búsqueda del conocimiento; finalmente se vislumbra o abre una posibilidad interpretativa acerca del interés que puede tener la proposición de una "poesía filosófica" en la obra de Platón.The following text will try to show that radicalization of the thesis expressed by Plato in the book X does not allow "to "estímate" the value that the Athenian philo-sopher knows that poetry possesses, since poetry might be a means for the reflexive exercise if it takes advantage of the sobriety that philosophy proposes. To carry out this task it is necessary to define three points on which this paper will be about: first, the author will inform the reader about the old discussion among poetry and philosophy to understand the context of the crisis between these two forms of teaching; Second, criticism established in the book X on the lack of rigor in the search of knowledge that poets have will be addressed. Finally, the paper glimpses or opens an interpretive possibility about the interest that the proposition of a "philosophical poetry" can have in Plato's work. (shrink)

This paper investigates the link between the consumer perception that a company is socially oriented and the consumer intention to buy products marketed by that company. We suggest that this link exists when at least two conditions prevail: (1) the products sold by that company comply with ethical and social requirements; (2) the company has an acknowledged commitment to protect consumer rights and interests. To test these hypotheses, we conducted a survey among the clients of retail chains offering Fair Trade (...) products. The results show that socially oriented companies can successfully leverage their reputation to market products with high symbolic values. (shrink)

Wenn eine Kultur etwas als Erfindung akzeptiert, dann hat dieses Etwas bereits den Status einer Tatsache erhalten, die vorhanden ist und auf ihren Nutzen oder auf ihre Funktion hin befragt werden kann. Was aber geschieht davor? Wie gewinnt das Erfundene Wirklichkeit? Wie in der Kunst, wie im Theater, wie in der Literatur und Musik, wie in der Wissenschaft? Und mit welchen Folgen? Die Beiträge in diesem Band beschäftigen sich alle mit einem Moment oder einem bestimmten Modell der Invention. Ausgehend von (...) den jeweils involvierten Medien wird der Versuch unternommen, diese Momente und Modelle zu rekonstruieren. Um etwas über die entsprechenden Inventionen in Erfahrung bringen zu können, werden diese als Ergebnisse oder Effekte von Improvisationsprozessen begriffen: Improvisationen in dem Sinne, dass von einem grundsätzlich offenen Zukunftsspielraum ausgegangen wird, gleichzeitig aber auch davon, dass es ein Umgebungs- und Verfahrenswissen gibt, das im Einzelfall beschrieben werden kann.

Åsa Burman has recently introduced the important notion of telic power and differentiated it from deontic power in an attempt to build a bridge between ideal and non-ideal social ontology. We find Burman’s project promising but we argue that more is to be done to make it entirely successful. First, there is a palpable tension between Burman’s claim that telic power can be ontologically independent of deontic power and her examples, which suggests that these forms of power share the same (...) basis. Second, it is not completely clear how telic power helps non-ideal social ontologists explain oppression, since Burman thinks that both forms of power are transparent to social agents. We offer solutions to both problems. First, we question the thesis that telic power can exist without deontic power. Burman contends that this is possible because some social roles involving telic power can exist independently of institutions, which are––in her opinion––the source of deontic power. Against Burman, we suggest that all social roles involve deontic power, whether or not they are institutional. Second, we argue that while the exercise of deontic power requires a mutual recognition of the social roles of the interacting agents and, therefore, an acceptance of the associated norms, the exercise of telic power does not require acceptance of the relevant norms. This is why invoking telic power is useful in explaining how oppression and injustice can arise. Lastly, we suggest that the relation between teleological normativity and telic power has not been fully clarified by Burman and requires a deeper analysis. (shrink)

We largely agree with Grimwade et al ’s1 conclusion that challenge trial participants may ethically be paid, including for risk. Here, we add further arguments, clarify some points from the perspective of economics and indicate areas where economists can support the development of a framework for ethically justifiable payment. Our arguments apply to carefully constructed and monitored controlled human infection model trials that have been appropriately reviewed and approved. Participants in medical studies perform a service. Outside the domain of research (...) participation, there is nearly universal agreement that workers providing a service should be compensated fairly, and that work involving more discomfort and risk should be compensated more generously. Accordingly, labour regulations impose floors, not caps on compensation. Caps, even if intended to protect against undue inducement, also raise concerns about illegal price-fixing that disadvantages workers. Such limits on payment for egg donors have successfully been challenged in court.i Moreover, caps on compensation may harm everyone at risk of infection, not just potential participants. Insufficient compensation may impede the recruitment of enough suitable subjects, for example, when representativeness of the subject sample is required. Delays in vaccine development not only prolong disruption of social, educational and economic activity but also lead to excess infections and deaths. Unlike paid CHIM participants, individuals exposed to such infection do not accept it voluntarily, are not compensated for it, and are unlikely to receive the level of medical supervision afforded to closely monitored CHIM participants. Payment caps can lead to attempts to circumvent the regulation. For example, many countries …. (shrink)

We compute the effect of collapse models on neutrino oscillations. The effect of the collapse is to modify the evolution of the spatial part of the wave function and we will show that this indirectly amounts to a change on the flavor components. For the analysis we use the mass proportional CSL model, and perform the calculation to second order perturbation theory. As we will show, the CSL effect is very small—mainly due to the very small mass of neutrinos—and practically (...) undetectable. (shrink)

La especulación filosófica suele observar que lo feo y el mal carecen de entidad y que sólo pueden ser considerados como una belleza y bondad menguadas. Sin embargo, esta disminución entitativa no constituye sólo una carencia, sino que además puede ofrecer en sí la posibilidad de una belleza y un bien mayores. En este sentido, pensar la belleza del mal no ha constituido para muchos autores antiguos y medievales una imposibilidad lógica, sino por el contrario una nueva manera de hablar (...) de la Belleza del Universo. Este ha sido el parecer agustino y dionisiano, y es también el que asume la conocida Summa Halensis, aunque desde una óptica cuya originalidad radica en la integración de esas tradiciones. Analizar cómo la Summa Halensis entiende que la belleza es capaz de integrar a lo malo, es la intención del presente trabajo. (shrink)

No hay duda que la cuestión de los trascendentales y su posible distinción atrajo la atención de los pensadores del siglo XIII. Sin embargo, este tema siguió caminos diversos. En tal sentido, la Summa Halensis propone un abordaje que no sólo delimita cada transcendental en sí, sino que además los incorpora al plano soteriológico humano. Así, el presente trabajo se ocupará de ambos aspectos.

Scholarly research largely converges on the argument that trust is of paramount importance to drive economic agents toward mutually satisfactory, fair, and ethically compliant behaviors. There is, however, little agreement on the meaning of trust, whose conceptualizations differ with respect to actors, relationships, behaviors, and contexts. At present, we know much better what trust does than what trust is. In this article, we present an extensive review and analysis of the most prominent articles on trust in market relationships. Using computer-aided (...) content analysis and network analysis methods, we identify key, recurring dimensions that guided the conceptualization of trust in past research, and show how trust can be developed as a multifaceted and layered construct. Our results are an important contribution to a convergence of research toward a shared and common view of the meaning of trust. This process is important to ensure the body of trust research's internal theoretical consistency, and to provide reliable and common principles for the management of business relationships — a context in which opportunism and imperfect information may induce economic actors to cheat and stray from fair and ethically compliant behaviors.

This book reexamines the birth of quantum mechanics, in particular examining the development of crucial and original insights of Bohr. In particular, it gives a detailed study of the development and the interpretation given to Bohr's Principle of Correspondence. It also describes the role that this principle played in guiding Bohr's research over the critical period from 1920 to 1927.

According to the theoretical framework relating hypnosis to attention, baseline attentional functioning in highly hypnotizable individuals should be more efficient than in low hypnotizable individuals. However, previous studies did not find differences in Stroop-like tasks in which the measure indicative of the Stroop interference effect was based on response latencies. This study was designed to determine whether subjects with different levels of hypnotic susceptibility show differences in baseline attentional functioning. To assess this hypothesis, high, medium, and low hypnotizable subjects performed (...) a Stroop task designed to evaluate accuracy performance, before being subjected to hypnotic induction. Results showed that the Stroop interference effect was smaller in high hypnotizable subjects than in low hypnotizable subjects, whereas it was not different between high, and medium hypnotizable subjects. This outcome supports the notion that baseline attentional functioning is related to hypnotic susceptibility. (shrink)

Within the deep philosophical reflection of the thirteenth century are commonly heard names such as Albertus Magnus, Thomas Aquinas and Bonaventure. However, little is said of those disciples of lesser brilliance who spread the thought of their teachers. Such is the case of Ulrich of Strasbourg. This Dominican friar, a fellow student of Thomas Aquinas in Cologne, studied under Albertus Magnus the De Divinis nominibus of Pseudo-Dionysius. Years later, Ulrich wrote a work called Summa de bono where, in dealing with (...) beauty, a unique Neoplatonic synthesis operates, but from the original perspective of his master. This paper analyses the concept of beauty present in Ulrich of Strasbourg to show how there is as much clear dependence on Albertian Neoplatonism as there is originality in the presentation of the topic.

I discuss two competing theories of the progressive: the theory proposed in Parsons (1980, 1985, 1989, 1990) and the theory proposed in Landman (1992). These theories differ in more than one way. Landman regards the progressive as an intentional operator, while Parsons doesn't. Moreover, Landman and Parsons disagree on what uninflected predicates denote. For Landman, cross the street has in its denotation complete events of crossing the street; the aspectual contribution of English simple past (perfective aspect) is the identity function. (...) For Parsons, both complete and incomplete events of crossing the street can be in the denotation of the base VP; perfective aspect restricts its denotation to the events that culminate. I present a version of ParsonÕs theory that avoids the problems raised by Landman, in particular the problem posed for Parsons by creation verbs. The repaired version and Landman's theory still differ in the way they analyze uninflected verbs. The repaired version and Landman's theory still differ in the way they analyze uninflected predicates. I present evidence from Slavic languages that both theories are needed. Finally, I discuss some evidence that may favor one or the other approach to the semantics of the English progressive. (shrink)

Resultado de uma investigação bibliográfica, o artigo promove aproximações e evidencia afastamentos entre Paulo Freire e Jürgen Habermas, dedicando especial ênfase ao possível impacto de suas ideias para os propósitos da práxis educativa na concepção popular. As conclusões enfatizam a fragilidade da proposta habermasiana e destacam a maior consistência da perspectiva freireana na luta contra a opressão social.

The text is a presentation of Gilles Deleuze's interpretation of Henri Bergson's philosophy. It aims at focus on subjects that deleuzean philosophy should return to, developing them in Différence et répetition and from this work. Among the most outstandings, we find the affirmative ontology subject, that involves the passage from virtual to actual through being differentiation process. Being doesn't stop to have existence by actualizing itself, but it differentiates itself in this process, being individualized as things. Being is thus pre-individual (...) and pre-subjective. In Bergson, there should be a virtual coexistence of all differences degrees in duration.Este texto é uma apresentação da interpretação feita por Gilles Deleuze da filosofia de Henri Bergson.

This article addresses the topic of artistic mímēsis, and attempts to illuminate the contemporary discussion between two seemingly irreconcilable positions. The first, framed in a traditional interpretation of Aristotelian texts, considers the work of art as an imitation of nature, finding in it its only rule. The second, supported by a different interpretation, states that, according to Aristotle himself, artistic creativity is fictional, that is, independent of natural reality, and therefore debtor only of the artist’s subjectivity. However, when considering the (...) analogy between téchnē and phýsis, within Aristotle’s teleological worldview, it is possible to notice a kind of “common work” that harmonizes them. In this context, and advancing on the consideration of the mimetic poiésis, the philosopher’s texts allow an interpretation that, without detaching itself from the original naturalness of art and taking it as a guide, opens the horizon to the artist’s creativity.

seguindo a linha interpretativa de Deleuze, em Diferença e repetição, o artigo apresenta como, em Aristóteles e em Platão, a diferença é de! nida desde a primazia da identidade e como Deleuze rompe com ela, ao definir a diferença em si mesma. A filosofia da diferença deleuziana se compõe a partir da apreensão da diferença como virtualidade positiva e imanente, constituinte da univocidade do ser. No mesmo movimento, ela comporta uma crítica a toda filosofia que busca subordinar a diferença à (...) representação, como em Aristóteles, em que a diferença está submetida à quádrupla raiz da identidade, da analogia, da oposição e da semelhança. Apesar disso, Deleuze explicita a noção de não-ser sem negação presente no So !sta de Platão como testemunho da potência da diferença em subverter a distinção modelo-cópia, ali onde havia um empenho em subordiná-la aos poderes da identidade e da semelhança.

Microfluidic technology – the manipulation of fluids at micrometer scales – has revolutionized many areas of synthetic biology. The bottom‐up synthesis of “minimal” cell models has traditionally suffered from poor control of assembly conditions. Giant unilamellar vesicles (GUVs) are good models of living cells on account of their size and unilamellar membrane structure. In recent years, a number of microfluidic approaches for constructing GUVs has emerged. These provide control over traditionally elusive parameters of vesicular structure, such as size, lamellarity, membrane (...) composition, and internal contents. They also address sophisticated cellular functions such as division and protein synthesis. Microfluidic techniques for GUV synthesis can broadly be categorized as continuous‐flow based approaches and droplet‐based approaches. This review presents the state‐of‐the‐art of microfluidic technology, a robust platform for recapitulating complex cellular structure and function in synthetic models of biological cells. (shrink)

In the context of propositional logics, we apply semantics modulo satisfiability—a restricted semantics which comprehends only valuations that satisfy some specific set of formulas—with the aim to efficiently solve some computational tasks. Three possible such applications are developed.We begin by studying the possibility of implicitly representing rational McNaughton functions in Łukasiewicz Infinitely-valued Logic through semantics modulo satisfiability. We theoretically investigate some approaches to such representation concept, called representation modulo satisfiability, and describe a polynomial algorithm that builds representations in the newly (...) introduced system. An implementation of the algorithm, test results and ways to randomly generate rational McNaughton functions for testing are presented. Moreover, we propose an application of such representations to the formal verification of properties of neural networks by means of the reasoning framework of Łukasiewicz Infinitely-valued Logic.Then, we move to the investigation of the satisfiability of joint probabilistic assignments to formulas of Łukasiewicz Infinitely-valued Logic, which is known to be an NP-complete problem. We provide an exact decision algorithm derived from the combination of linear algebraic methods with semantics modulo satisfiability. Also, we provide an implementation for such algorithm for which the phenomenon of phase transition is empirically detected.Lastly, we study the game theory situation of observable games, which are games that are known to reach a Nash equilibrium, however, an external observer does not know what is the exact profile of actions that occur in a specific instance; thus, such observer assigns subjective probabilities to players actions. We study the decision problem of determining if a set of these probabilistic constraints is coherent by reducing it to the problems of satisfiability of probabilistic assignments to logical formulas both in Classical Propositional Logic and Łukasiewicz Infinitely-valued Logic depending on whether only pure equilibria or also mixed equilibria are allowed. Such reductions rely upon the properties of semantics modulo satisfiability. We provide complexity and algorithmic discussion for the coherence problem and, also, for the problem of computing maximal and minimal probabilistic constraints on actions that preserves coherence.prepared by Sandro Márcio da Silva Preto.E-mail: [email protected]:https://doi.org/10.11606/T.45.2021.tde-17062021-163257.

O livro Paulo Freire: uma arqueologia bibliográfica é fruto de um denso esforço investigativo que reuniu pesquisadores(as) brasileiros(as) sobre o pensamento freireano, buscando analisar e evidenciar o conjunto de influências presentes em sua obra. Na forma de uma arqueologia, escava o conjunto de escritos de Freire desde o final dos anos de 1950, até as obras publicadas postumamente. Como resultado, elenca e analisa no formato de verbetes 501 presenças identificadas nos seus livros, incluindo autores e autoras, instituições, pessoas, lugares e (...) fatos históricos, proporcionando aos leitores e às leitoras um amplo panorama teórico e conceitual do seu pensamento político e pedagógico. Portanto, este livro é indicada a estudantes, pesquisadores e demais interessados em compreender a complexa e densa estrutura teórica que Paulo Freire consolidou em seus mais de 30 livros publicados. A expressão “Arqueologia bibliográfica” pretende remeter à compreensão que o próprio Paulo Freire tinha da consciência, respectivamente da conscientização, como uma construção histórica composta por complexas tramas que se relacionam de muitas formas, ora se contrapondo, ora se complementando ou confirmando, todas elas compondo um estar-no-mundo único. O livro apresenta instrumentos que auxiliam a encontrar peças e rastros deixados nas páginas por esse nosso grande educador, que inspirem olhares mais profundos e mais largos sobre a educação em nosso tempo. Com as informações sobre a bibliografia referida neste livro, cada leitor e cada leitora poderá compor com mais propriedade a sua própria narrativa sobre Paulo Freire e sua obra. (shrink)

This article aims to offer some notes related to the question of the insecurity and fear in urban life. Constitutive condition of many, if not all, contemporary societies, fear and insecurity in urban space, or, in public space, are here analized from two thinkers. The sociologist Zygmunt Bauman is present insofar as he considers the fear a constitutive aspect on two life dimensions : on the fragility and the human contingence towards nature, and on the society itself, constituted by rules (...) and norms. The philosopher Giorgio Agamben is here emphasized on two oportunities. The first, when showing the impossibility of experiences made by human on the current societies context. The second when noting contemporary societies as following the concentration camp paradigm. Starting with these two authors, is found the necessity of rescue the public experience, resignify the economy and revalue the political economy. (shrink)

What are words? How should words be individuated? Such questions set the agenda for the metaphysics of words. Unfortunately, misunderstandings are piling up in this field. Although the discussion between Kaplan, Cappelen, Hawthorne, Lepore and others has given rise to interesting insights into many aspects of words, I contend that the debate is highly compromised by a lack of clarity about the questions in the first place. The purpose of this article is to partially clarify the debate on the metaphysics (...) of words by examining the very nature of the questions to be addressed. I shall differentiate three inquiries about words and shall provide explanations of why misunderstandings can and do arise. I claim that, in so doing, we may put the debate back on solid footing in order to rethink the real nature of words. (shrink)

In Italian Sign Language (LIS), when past or future time adverbs are present, the signs for verbs exhibit the same manual configurations whether the sentence reports a past event or a future event. Facts of this kind, also observed for American Sign Language (ASL) and other sign languages, have led some authors (Friedman, among others) to conclude that these languages, on a par with spoken languages like Chinese, lack grammatical tense. Neidle et al. and Jacobowitz and Stokoe have challenged this (...) view for ASL and have argued that ASL sentences contain tense markers. I present some data showing that LIS verbs inflect for tense. I argue, moreover, that the apparent lack of tense inflection when LIS past and future time adverbs are present is due to the fact that these adverbs shift the s-point and that LIS past and future tenses are absolute tenses. I provide a formal account of the LIS tense system based on these assumptions. The account is implemented in Heim’s analysis of tense. (shrink)

Eliminative materialists argue that we can overcome the phenomenological gap between two different ways of referring to our subjective experiences – either as introspectively grasped in terms of folk psychology or as explained in neurological terms – by abandoning the pre-scientific concepts of folk psychology. However, unless these theorists can offer a plausible explanation for why the scientific view of the human mind proposed by cognitive neuroscience is so deeply counter-intuitive, this argument will remain unconvincing. In order to address the (...) difficulties involved in making the paradigm shift from folk psychology to cognitive neuroscience I briefly review the theoretical revolution that marked the transition from classical mechanics to the theory of relativity at the beginning of 20th century; identify some similarities between this paradigm shift in physics and the birth of a new scientific view of the mind; explain by means of and why neurological theories that reduce consciousness and the Self to aspects of brain dynamics appear implausible from a common sense perspective despite being sound from a scientific point of view.

Collapse models predict the spontaneous collapse of the wave function, in order to avoid the emergence of macroscopic superpositions. In their mass-dependent formulation, they claim that the collapse of any system’s wave function depends on its mass. Neutral K, D, B mesons are oscillating systems that are given by Nature as superposition of two distinct mass eigenstates. Thus they are unique laboratory for testing collapse models that are sensitive to the mass. In this paper we derive—for the single mesons and (...) bipartite entangled mesons—the effect of the mass-proportional CSL (Continuous Spontaneous Localization) collapse model on the dynamics on neutral mesons. We compare the theoretical prediction with experimental data from different accelerator facilities. (shrink)

This article argues that a manuscript dated to the summer of 1927 by the editors of Bohr’s Collected Works was written a year earlier. The re-dating allows the conclusion that Bohr was well on his way to complementarity before his famous fight with Heisenberg over the uncertainty principle early in 1927. The literature that assumes that complementarity was Bohr’s response to Heisenberg is therefore in error. The editors of the Collected Works assigned the document the date of 1927 because it (...) refers to electron-diffraction experiments by Davisson and Germer, which were published in 1927. But as the article points out, Bohr and other leading physicists such as Max Born met Davisson in Britain in 1926 and discussed the experiments with him then. That demolished the basis of the earlier dating. Finally, the article argues that when the document takes its place between the Bohr–Kramers–Slater theory (1924) and the 1927 drafts of complementarity, everything falls neatly into place. (shrink)
