Content-based authorship identification is an emerging research problem in online social media networks, due to a wide collection of issues ranging from security to privacy preservation, from radicalization to defamation detection, and so forth. Indeed, this research has attracted a relevant amount of attention from the research community during the past years. The general problem becomes harder when we consider the additional constraint of identifying the same false profile over different social media networks, under obvious considerations. Inspired by this emerging (...) research challenge, in this paper we propose and experimentally assess an innovative framework for supporting content-based authorship identification and analysis in social media networks.

Libertas philosophandi è una indagine del rapporto disciplinare tra filosofia e teologia che ruota intorno alla celebre Lettera alla granduchessa Cristina di Lorena di G. Galilei, lettera-trattato con cui lo scienziato cerca di salvare uno spazio di libertà di ricerca nel contesto della cultura controriformata. La prima parte del libro illustra criticamente le polemiche sorte a partire dalla pubblicazione del Sidereus nuncius e proseguite fino alla condanna del copernicanesimo nel 1616. La seconda è dedicata all'analisi strutturale della Lettera e alla (...) ricerca delle fonti testuali che l'hanno ispirata, identificandone talora l'edizione precisa. La terza parte sviluppa i diversi temi della Lettera, presentando alcuni elementi fin qui ignoti o ignorati, tra i quali un forte indebitamento con la tradizione del trattato aristotelico De anima (in particolare con Giovanni Pico della Mirandola, Pietro Pomponazzi e Cesare Cremonini); la scoperta di un plagio da parte di Cremonini; la sensibilità politica di Galileo. Viene poi discusso il problema del cosiddetto concordismo del trattato e proposta una lettura controcorrente; si presenta una analisi iconografica che evidenzia, tra l'altro, il legame tra la Lettera a Cristina e l'Accademia dei Lincei. Ancora, si offre un documento inedito che getta luce sul ruolo del cardinale Bellarmino nella condanna del 1616. Infine una rilettura dei documenti dei due processi a Galileo mostra come una lieve, ma decisiva manipolazione della sentenza del primo processo riproponga la problematicità del secondo. La quarta parte del libro contiene il testo della Lettera accompagnato da numerose note di commento storico. (shrink)

Philosophers of perception frequently assume that we see actual states of affairs, or facts. Call this claim factualism. In his book, William Fish suggests that factualism is supported by phenomenological observation as well as by experimental studies on multiple object tracking and dynamic feature-object integration. In this paper, I examine the alleged evidence for factualism, focusing mainly on object detection and tracking. I argue that there is no scientific evidence for factualism. This conclusion has implications for studies on the phenomenology (...) and epistemology of visual perception. (shrink)

La recepción europea de Gómez Dávila comenzó a desplegarse de manera más amplia a partir de la lectura y difusión realizada por Franco Volpi. Este artículo alude a la manera como dicha lectura concretó las interpretaciones del colombiano, principalmente a la luz de una filosofía práctica y una perspectiva crítica. De dichas posturas, el italiano destaca la vocación vital y el carácter provocador del pensamiento de Gómez Dávila.

Introduction to the topical collection "The Structure of Perceptual Objects"—with contributions by Mohan Matthen, EJ Green, Alisa Mandrigin, Blazej Skrzypulec, and Anna Drożdżowicz.

At the beginning of the 20th century, Gestalt psychologists put forward the concept of psychoneural isomorphism, which was meant to replace Fechner’s obscure notion of psychophysical parallelism and provide a heuristics that may facilitate the search for the neural correlates of the mind. However, the concept has generated much confusion in the debate, and today its role is still unclear. In this contribution, I will attempt a little conceptual spadework in clarifying the concept of psychoneural isomorphism, focusing exclusively on conscious (...) visual perceptual experience and its neural correlates. Firstly, I will outline the history of our concept, and its alleged metaphysical and epistemic roles. Then, I will clarify the nature of isomorphism and rule out its metaphysical role. Finally, I will review some epistemic roles of our concept, zooming in on the work of Jean Petitot, and suggest that it does not play a relevant heuristic role. I conclude suggesting that psychoneural isomorphism might be an indicator of robustness for certain mathematical descriptions of perceptual content. (shrink)

Is consistency the sort of thing that could provide a guide to mathematical ontology? If so, which notion of consistency suits this purpose? Mark Balaguer holds such a view in the context of platonism, the view that mathematical objects are non-causal, non-spatiotemporal, and non-mental. For the purposes of this paper, we will examine several notions of consistency with respect to how they can provide a platon-ist epistemology of mathematics. Only a Gödelian notion, we suggest, can provide a satisfactory guide to (...) a platonist ontology. Is consistency the sort of thing that could provide a guide to mathematical ontology? If so, which notion of consistency suits this purpose? Mark Bala-guer holds such a view in the context of platonism, the view that mathematical objects are non-causal, non-spatiotemporal, and non-mental. Balaguer's version of Platonism, Full-Blooded Platonism (FBP), is the view that "there are as many abstract mathematical objects as there could be-i.e., there actually exist abstract mathematical objects of all possible kinds" (Balaguer, 2017, p. 381). He continues: Since FBP says that there are abstract mathematical objects of all possible kinds, it follows that if FBP is true, then every purely mathematical theory that could be true-i.e., that is internally consistent-accurately describes some collection of actually existing abstract objects. Thus it follows from FBP that in order to acquire knowledge of abstract objects, all we have to do is come up with an internally consistent purely mathematical theory (and know that it is internally consistent).

Este artículo analiza en primera instancia la lectura y consideración hermenéutica que Ernesto Volkening realiza de la obra de Nicolás Gómez Dávila. Tras una presentación de las pautas interpretativas que se dan en el Diario de lectura de Volkening, se considera luego el interés de losautores por la arquitectura y el urbanismo modernos, como claves para la crítica del modo de vida reificante del hombre actual. Posteriormente, se ilustran las pautas que abordan la historia y la historicidad, bajo la idea (...) de una comprensión hermenéutica gestada en los contextos, opuesta a cualquier determinismo y puesta en marcha bajo la impronta de la singularidad e individualidad.

Healthcare professionals often face ethical conflicts and challenges related to decision-making that have necessitated consideration of the use of conscientious objection (CO). No current guidelines exist within Spain’s healthcare system regarding acceptable rationales for CO, the appropriate application of CO, or practical means to support healthcare professionals who wish to become conscientious objectors. As such, a procedural framework is needed that not only assures the appropriate use of CO by healthcare professionals but also demonstrates its ethical validity, legislative compliance through (...) protection of moral freedoms and patients’ rights to receive health care. Our proposal consists of prerequisites of eligibility for CO (individual reference, specific clinical context, ethical justification, assurance of non-discrimination, professional consistency, attitude of mutual respect, assurance of patient rights and safety) and a procedural process (notification and preparation, documentation and confidentiality, evaluation of prerequisites, non-abandonment, transparency, allowance for unforeseen objection, compensatory responsibilities, access to guidance and/or consultative advice, and organizational guarantee of professional substitution). We illustrate the real-world utility of the proposed framework through a case discussion in which our guidelines are applied. (shrink)

Contemporary theories of consciousness are based on widely different concepts of its nature, most or all of which probably embody aspects of the truth about it. Starting with a concept of consciousness indicated by the phrase “the feeling of what happens” (the title of a book by Antonio Damásio), we attempt to build a framework capable of supporting and resolving divergent views. We picture consciousness in terms of Reality experiencing itself from the perspective of cognitive agents. Each conscious experience is (...) regarded as composed of momentary feeling events that are combined by recognition and evaluation into extended conscious episodes that bind cognitive contents with a wide range of apparent durations (0.1 secs to 2 or more secs, for us humans, depending on circumstances and context). Three necessary conditions for the existence of consciousness are identified: a) a ground of Reality, envisaged as an universal field of potentiality encompassing all possible manifestations, whether material or 'mental'; b) a transitional zone, leading to; c) a manifest world with its fundamental divisions into material, 'informational' and quale-endowed aspects. We explore ideas about the nature of these necessary conditions, how they may relate to one another and whether our suggestions have empirical implications. (shrink)

The sensorimotor theory of vision and visual consciousness is often described as a radical alternative to the computational and connectionist orthodoxy in the study of visual perception. However, it is far from clear whether the theory represents a significant departure from orthodox approaches or whether it is an enrichment of it. In this study, I tackle this issue by focusing on the explanatory structure of the sensorimotor theory. I argue that the standard formulation of the theory subscribes to the same (...) theses of the dynamical hypothesis and that it affords covering-law explanations. This however exposes the theory to the mere description worry and generates a puzzle about the role of representations. I then argue that the sensorimotor theory is compatible with a mechanistic framework, and show how this can overcome the mere description worry and solve the problem of the explanatory role of representations. By doing so, it will be shown that the theory should be understood as an enrichment of the orthodoxy, rather than an alternative. (shrink)

Trecho da obra: "Nos itinerários históricos mais recentes, o corpo atlético, de alto rendimento, tornou-se metáfora da superação de si e lugar de sacralização de quase ilimitados recursos tecnocientíficos. (...) O desempenho dos corpos no campo desportivo pode ser compreendido como concretização daquela mitologia do progresso que moldou a experiência do tempo na modernidade. (...) Os trânsitos entre desporto, ética e transcendência foram o objecto de estudo e reflexão de um colóquio internacional realizado na Universidade Católica Portuguesa, e o presente (...) volume, dando continuidade a uma política de publicação do Instituto Português do Desporto e Juventude / Plano Nacional de Ética no Desporto, reúne os textos apresentados, procurando, assim, atingir um público mais amplo e contribuir para o aprofundamento desta linha de indagação na sociedade portuguesa.".

El artículo analiza cualitativamente la relación entre infancia y violencia en el contexto de la guerra civil en El Salvador (1980-1992). La reflexión es vehiculada por el examen de la película Voces inocentes (2004), como una obra socialmente producida y como una representación de la realidad histórica de índole prospectiva. El trabajo destaca el mérito del filme al visibilizar y denunciar la responsabilidad de los sustentadores primarios de la violencia ‒aún hoy impune‒ hacia la infancia salvadoreña, cuyas secuelas psicosociales constituyeron, (...) a la postre, un entorno sociohistórico centroamericano signado por una debacle humanitaria que comenzó hace cuatro décadas, en un tránsito infausto “de la locura a la esperanza”. Para ello, he empleado el marco teórico conceptual sobre la violencia desarrollado por el jesuita vasco-salvadoreño, Ignacio Ellacuría, según el cual, las violencias resultantes solo pueden ser valoradas a partir de la crítica inicial a la violencia originaria de carácter estructural.

In a broad-based study of experiences in psychological research, 65 undergraduates participating in a wide range of psychological experiments were interviewed in depth. Overall findings demonstrated that participants hold varying views, with only 32% of participants characterizing their experiences as completely positive. Participants' descriptions of their debriefing experiences suggest substantial variability in the content, format, and general quality of debriefing practices. Just over 40% of the debriefing experiences were viewed favorably. Positive debriefing experiences were described as including a thorough explanation (...) of the study and detailed information concerning the broader relevance of the experiment to the field of psychology. The most common complaint, characterizing 28.8% of the responses, was that the debriefing was unclear and that insufficient information was provided. Participants' views of psychological research and the discipline of psychology were also elicited. Results are discussed in terms of ethical and methodological implications. (shrink)

The activism of institutional investors tends more and more toward the supervision and control of the behavior of the managers of big companies. In this article, we present a model based on the creation of an activism index that lets us evaluate such activism's effect on the sensitivity of the investment policies of a company in the face of financial variables and market variables. To test our assertions, we analyze firm-level data for United Kingdom, Germany, France, Denmark, and Spain during (...) the period 1995-2004. Our results point to a significant reduction in the sensitivity of company investment decisions in the face of these variables, especially relative to intangible capital, as a result of the neutralizing effect of activism on the high agency costs of free cash flow and on the information asymmetries of the market.

The Critique of Pure Reason—Kant’s First Critique—is one of the most studied texts in intellectual history, but as Alfredo Ferrarin points out in this radically original book, most of that study has focused only on very select parts. Likewise, Kant’s oeuvre as a whole has been compartmentalized, the three Critiques held in rigid isolation from one another. Working against the standard reading of Kant that such compartmentalization has produced, The Powers of Pure Reason explores forgotten parts of the First (...) Critique in order to find an exciting, new, and ultimately central set of concerns by which to read all of Kant’s works. Ferrarin blows the dust off of two egregiously overlooked sections of the First Critique—the Transcendental Dialectic and the Doctrine of Method. There he discovers what he argues is the Critique’s greatest achievement: a conception of the unity of reason and an exploration of the powers it has to reach beyond itself and legislate over the world. With this in mind, Ferrarin dismantles the common vision of Kant as a philosopher writing separately on epistemology, ethics, and aesthetics and natural teleology, showing that the three Critiques are united by this underlying theme: the autonomy and teleology of reason, its power and ends. The result is a refreshing new view of Kant, and of reason itself. (shrink)
