The investigation of how humans perceive and respond to emotional signals conveyed by the human body has been for a long time secondary compared with the investigation of facial expressions and emotional scenes recognition. The aims of this behavioral study were to assess the ability to process emotional body postures and to test whether motor response is mainly driven by the emotional content of the picture or if it is influenced by motor resonance. Emotional body postures and scenes (IAPS) divided (...) into three clusters (fear, happiness, and neutral) were shown to 25 healthy subjects (13 males, mean age ± SD: 22.3 ± 1.8 years) in a three-alternative forced choice task. Subjects were asked to recognize the emotional content of the pictures by pressing one of three keys as fast as possible in order to estimate response times (RTs). The rating of valence and arousal was also performed. We found shorter RTs for fearful body postures as compared with happy and neutral postures. In contrast, no differences across emotional categories were found for the IAPS stimuli. Analysis on valence and arousal and the subsequent item analysis showed an excellent reliability of the two sets of images used in the experiment. Our results show that fearful body postures are rapidly recognized and processed, probably thanks to the automatic activation of a series of central nervous system structures orchestrating the defensive threat reactions, strengthening and supporting previous neurophysiological and behavioral findings in body language processing.

This paper develops a probabilistic analysis of conditionals which hinges on a quantitative measure of evidential support. In order to spell out the interpreta- tion of ‘if’ suggested, we will compare it with two more familiar interpretations, the suppositional interpretation and the strict interpretation, within a formal framework which rests on fairly uncontroversial assumptions. As it will emerge, each of the three interpretations considered exhibits specific logical features that deserve separate consideration.

Epistemologists and philosophers of science have often attempted to express formally the impact of a piece of evidence on the credibility of a hypothesis. In this paper we will focus on the Bayesian approach to evidential support. We will propose a new formal treatment of the notion of degree of confirmation and we will argue that it overcomes some limitations of the currently available approaches on two grounds: (i) a theoretical analysis of the confirmation relation seen as an extension of (...) logical deduction and (ii) an empirical comparison of competing measures in an experimental inquiry concerning inductive reasoning in a probabilistic setting.

This paper outlines an account of conditionals, the evidential account, which rests on the idea that a conditional is true just in case its antecedent supports its consequent. As we will show, the evidential account exhibits some distinctive logical features that deserve careful consideration. On the one hand, it departs from the material reading of ‘if then’ exactly in the way we would like it to depart from that reading. On the other, it significantly differs from the non-material accounts which (...) hinge on the Ramsey Test, advocated by Adams, Stalnaker, Lewis, and others. (shrink)

Harrigan and Spekkens, introduced the influential notion of an ontological model of operational quantum theory. Ontological models can be either “epistemic” or “ontic.” According to the two scholars, Einstein would have been one of the first to propose an epistemic interpretation of quantum mechanics. Pusey et al. showed that an epistemic interpretation of quantum theory is impossible, so implying that Einstein had been refuted. We discuss in detail Einstein’s arguments against the standard interpretation of QM, proving that there is a (...) misunderstanding in Harrigan and Spekkens’ attribution of an epistemic perspective to Einstein, whose point of view was actually statistical, but in a quasi-classical sense.

O artigo apresenta as lutas dos trabalhadores rurais boias frias no Brasil, valorizando sua riqueza e protagonismo em momentos históricos em que elas eram invisibilizadas tanto pela ditadura como por visões pré-concebidas de quem seriam os sujeitos das lutas por reforma agrária. O universo empírico da pesquisa é a região de Ribeirão Preto e Araraquara, no estado de São Paulo, representativa das contradições entre uma agricultura produtivista e a proletarização de um amplo contingente de trabalhadores. A partir deste contexto, propõe-se (...) uma metodologia centrada nas especificidades das lutas, não deduzidas das condições objetivas, mas marcada pelas experiências vividas pelos trabalhadores e pela identificação de seus interesses.

The article aims to define the role assumed by Paul Cézanne’s pictorial landscape within aesthetic reflections on landscape. Starting with the testimonies of Emile Bernard, Joachim Gasquet and Maurice Denis, the aim is to identify those concepts and components that aesthetically constitute and characterise the landscape of Mont Sainte-Victoire. In this sense we wish to proceed with an investigation aimed at the aesthetic-perceptual reading provided by Maurice Merleau-Ponty, focusing on the parameters of vision, colour and depth, and then turn our (...) attention to the motif analysed by Henri Maldiney, through the concepts of form and rhythm.

The aim of this paper is to trace a pathway connecting contemplative knowledge and practices with the social sciences. Contemplative knowledge and practices offer material for reflection in social science even concerning their very foundation. I'll found an opportunity for meshing our disciplinary tools with this knowledge as I introduced it in a health promotion program. The result will be a transdisciplinary confluence of different lines of inquiry contributing to a new perspective of self and social action. First of all (...) I will give a definition of contemplative knowledge and practices. Then, I will make a bridge between the contemplative approach and the social sciences, showing the contribution that symbolic interactionism can play. I will illustrate the perspective drawing on an action research program called Auriga aimed at smoking cessation and reduction among health professionals. The aim of this paper is focused on the specification of the conceptual background in which such kind of program has been developed. Finally, I outline some implications it could represent for what might be called transformative sociology. I believe that contemplative knowledge could contribute to disentangle some of the unanswered questions and concerns in the social sciences, once they dismiss for a while their scientistic perspective. The secular redefinition of tools mainly belonging to the wisdom traditions represents an innovation that can reshape what we intend by the self and experience, contributing to what is called the “social transformation from within,” a pragmatic and wise approach to change at any level.

Questo articolo si sofferma su alcuni aspetti della relazione tra performance musicali e registrazioni sonore. Dopo una breve introduzione sul tema dell'improvvisazione in musica, cerco di integrare due dei contributi teorici più rilevanti della filosofia di Maurizio Ferraris – la ridefinizione dell’estetica intesa come “scienza della percezione sensibile” e la teoria della documentalità – per far luce su alcuni dei temi più discussi in filosofia della musica: l'ontologia della performance, la registrazione su supporti sia fisici che (apparentemente) immateriali, e infine (...) il ruolo cruciale giocato dalla tecnologia, e in particolare da Internet, nel rendere disponibile contemporaneamente a milioni di utenti sterminate quantità di musica archiviata in memorie dalla capienza praticamente infinita.

In the past few years, social epistemologists have developed several formal models of the social organisation of science. While their robustness and representational adequacy has been analysed at length, the function of these models has begun to be discussed in more general terms only recently. In this article, I will interpret many of the current formal models of the scientific community as representing the latest development of what I will call the ‘Kuhnian project’. These models share with Kuhn a number (...) of questions about the relation between individuals and communities. At the same time, they also inherit some of Kuhn’s problematic characterisations of the scientific community. In particular, current models of the social organisation of science represent the scientific community as essentially value-free. This may put into question both their representational adequacy and their normative ambitions. In the end, it will be shown that the discussion on the formal models of the scientific community may contribute in fruitful ways to the ongoing debates on value judgements in science. (shrink)

The so‐called problem of irrelevant conjunction has been seen as a serious challenge for theories of confirmation. It involves the consequences of conjoining irrelevant statements to a hypothesis that is confirmed by some piece of evidence. Following Hawthorne and Fitelson, we reconstruct the problem with reference to Bayesian confirmation theory. Then we extend it to the case of conjoining irrelevant statements to a hypothesis that is dis confirmed by some piece of evidence. As a consequence, we obtain and formally present (...) a novel and more troublesome problem of irrelevant conjunction. We conclude by indicating a possible solution based on a measure‐sensitive approach and by critically discussing a major alternative way to address the problem. *Received December 2008; revised August 2009. †To contact the authors, please write to: Department of Philosophy, University of Turin, via Sant'Ottavio 20, 10124 Turin, Italy; e‐mail: vincenzo[email protected] ; [email protected] or [email protected].

Searching for information is critical in many situations. In medicine, for instance, careful choice of a diagnostic test can help narrow down the range of plausible diseases that the patient might have. In a probabilistic framework, test selection is often modeled by assuming that people's goal is to reduce uncertainty about possible states of the world. In cognitive science, psychology, and medical decision making, Shannon entropy is the most prominent and most widely used model to formalize probabilistic uncertainty and the (...) reduction thereof. However, a variety of alternative entropy metrics (Hartley, Quadratic, Tsallis, Rényi, and more) are popular in the social and the natural sciences, computer science, and philosophy of science. Particular entropy measures have been predominant in particular research areas, and it is often an open issue whether these divergences emerge from different theoretical and practical goals or are merely due to historical accident. Cutting across disciplinary boundaries, we show that several entropy and entropy reduction measures arise as special cases in a unified formalism, the Sharma–Mittal framework. Using mathematical results, computer simulations, and analyses of published behavioral data, we discuss four key questions: How do various entropy models relate to each other? What insights can be obtained by considering diverse entropy models within a unified framework? What is the psychological plausibility of different entropy models? What new questions and insights for research on human information acquisition follow? Our work provides several new pathways for theoretical and empirical research, reconciling apparently conflicting approaches and empirical findings within a comprehensive and unified information‐theoretic formalism.

This article aims at sketching a philosophical theory of sound based on the perspective of sound designers: unique agents blurring the boundaries between engineering, music, acoustics and sound-based art. After having introduced the general framing in Section 1, focusing on a short history of the theory and practice of sound design, in Section 2 we propose a reading of sound as monad. We derive such intuition from the technology of digital sampling of audio signals, based on the decomposition of complex (...) sound waves in a number of elementary sinusoidal waves. Thus, in Section 3, we attempt at grounding the resulting “sound-atom” on Leibniz’s notion of monad, intended both as a “simple substance without parts” and as a “nucleus of forces in statu possibilitatis.” The insight is resumed and further discussed in Section 4, where we draw our conclusions by demonstrating the fitness of such framing with regards to the standpoint of sound design, while accounting for the work of sound artists Carsten Nicolai and Ryoji Ikeda.

This article begins by surveying the names of the Father and their occurrences in the Cassiciacum Dialogues, then moves from language to ideas. It explores the meaning, sources and content of notions associated with each named Father. It concludes with a philosophical synthesis focused on the theoretical features of the figure of “the Father”, which conforms with Christian faith as interpreted through careful use of neoplatonic thought.

We discuss the probabilistic analysis of explanatory power and prove a representation theorem for posterior ratio measures recently advocated by Schupbach and Sprenger. We then prove a representation theorem for an alternative class of measures that rely on the notion of relative probability distance. We end up endorsing the latter, as relative distance measures share the properties of posterior ratio measures that are genuinely appealing, while overcoming a feature that we consider undesirable. They also yield a telling result concerning formal (...) accounts of explanatory power versus inductive confirmation, thereby bridging our discussion to a so-called no-miracle argument. (shrink)

In his late years, Thomas Kuhn became interested in the process of scientific specialization, which does not seem to possess the destructive element that is characteristic of scientific revolutions. It therefore makes sense to investigate whether and how Kuhn’s insights about specialization are consistent with, and actually fit, his model of scientific progress through revolutions. In this paper, I argue that the transition toward a new specialty corresponds to a revolutionary change for the group of scientists involved in such a (...) transition. I will clarify the role of the scientific community in revolutionary changes and characterize the incommensurability across specialties as possessing both semantic and methodological aspects. The discussion of the discovery of the structure of DNA will serve both as an illustration of my main argument and as reply to one criticism raised against Kuhn—namely, that his model cannot capture cases of revolutionary yet non-disruptive episodes of scientific progress. Revisiting Kuhn’s ideas on specialization will shed new light on some often overlooked features of scientific change. (shrink)

En este libro, que aparece en Italia en 1987, publicado muchas veces y muy comentado también en el extranjero, Vincenzo Ferrari analiza las funciones sociales del derecho en una perspectiva relativista, subjetivista y conflictualista, opuesta a la del funcionalismo sociológico. De tal manera, el derecho se revela como un medio de acción social dirigido a lograr los proyectos de seres humanos empeñados en relaciones variables de cooperación y de lucha. Así, se muestra cómo las normas jurídicas pueden orientar las (...) actitudes y desorientarlas; solucionar los conflictos y agravarlos o fomentarlos; legitimar cualquier forma de poder con argumentos tan válidos como ficticios. Solo al nivel de los ideales se redescubre el valor del derecho, su potencialidad libertadora y su naturaleza igualitaria. (shrink)

Probability ratio and likelihood ratio measures of inductive support and related notions have appeared as theoretical tools for probabilistic approaches in the philosophy of science, the psychology of reasoning, and artificial intelligence. In an effort of conceptual clarification, several authors have pursued axiomatic foundations for these two families of measures. Such results have been criticized, however, as relying on unduly demanding or poorly motivated mathematical assumptions. We provide two novel theorems showing that probability ratio and likelihood ratio measures can be (...) axiomatized in a way that overcomes these difficulties. (shrink)

Splicing is an efficient and precise mechanism that removes noncoding regions from a single primary RNA transcript. Cutting and rejoining of the segments occurs on nascent RNA. Trans-splicing between small specialized RNAs and a primary transcript has been known in some organisms but recent papers show that trans-splicing between two RNA molecules containing different coding regions is the normal mode in a Drosophila gene.1-3 The mod(mdg4) gene produces 26 different mRNAs encoding as many protein isoforms. The differences lie in alternative (...) 3′ exons encoded by different transcriptional units and spliced to the 5′ common region by a surprising trans-splicing mechanism.
