Children usually use the external and physical features of characters in movies or stories as a means of categorizing them quickly as being either good or bad/evil. This categorization is probably done by means of heuristics and previous experience. However, the study of this fast processing is difficult in children. In this paper, we propose a new experimental paradigm to determine how these decisions are made. We used illustrations of characters in folk tales, whose visual representations contained features that were (...) compatible or incompatible with the moral identity of the characters. Sixteen children between 8 and 10 years old participated in the experiment. We measured their electrodermal activity when they were listening to the story and looking at pictures of the characters. Results revealed a higher increase in skin conductance when the illustrations showed a moral condition that was incompatible with the actions of a character than when they showed one that was compatible. These results suggest that children make fast decisions about the moral identity of characters based on their physical features. They open up new possibilities in the study of the processing of moral decisions in children. (shrink)

The rapid dynamics of COVID-19 calls for quick and effective tracking of virus transmission chains and early detection of outbreaks, especially in the “phase 2” of the pandemic, when lockdown and other restriction measures are progressively withdrawn, in order to avoid or minimize contagion resurgence. For this purpose, contact-tracing apps are being proposed for large scale adoption by many countries. A centralized approach, where data sensed by the app are all sent to a nation-wide server, raises concerns about citizens’ privacy (...) and needlessly strong digital surveillance, thus alerting us to the need to minimize personal data collection and avoiding location tracking. We advocate the conceptual advantage of a decentralized approach, where both contact and location data are collected exclusively in individual citizens’ “personal data stores”, to be shared separately and selectively, voluntarily, only when the citizen has tested positive for COVID-19, and with a privacy preserving level of granularity. This approach better protects the personal sphere of citizens and affords multiple benefits: it allows for detailed information gathering for infected people in a privacy-preserving fashion; and, in turn this enables both contact tracing, and, the early detection of outbreak hotspots on more finely-granulated geographic scale. The decentralized approach is also scalable to large populations, in that only the data of positive patients need be handled at a central level. Our recommendation is two-fold. First to extend existing decentralized architectures with a light touch, in order to manage the collection of location data locally on the device, and allow the user to share spatio-temporal aggregates—if and when they want and for specific aims—with health authorities, for instance. Second, we favour a longer-term pursuit of realizing a Personal Data Store vision, giving users the opportunity to contribute to collective good in the measure they want, enhancing self-awareness, and cultivating collective efforts for rebuilding society.

En este trabajo se analiza el recurso a la escatología y al universo profético-apocalíptico de orientación antiliberal durante la consumación de la independencia de México, en 1821. Las diversas fuentes impresas utilizadas revelan la importancia que adquirieron los discursos sibilinos en la transición del virreinato al Imperio, así como su potencial movilizador. Se argumenta que estos sirvieron para denunciar el liberalismo revolucionario, fomentar la alternativa emancipadora y proponer lecturas mesiánicas renovadas. A través de esos tres aspectos se exploran las posibilidades (...) del pensamiento escatológico y del marco profético a la hora de comprender los cambios político-religiosos del periodo de las independencias iberoamericanas.

En este artículo se aborda la evolución de la exploración del espacio, discutiendo que el institucionalismo haya sido el motor de su régimen jurídico, pese a lo que en primera instancia se podrí inducir del OST de 1967. Asimismo, se analizan los flecos de dicho Tratado, tanto en lo referente a la militarización del espacio, como en lo relativo a la hipotética explotación económica de sus recursos. Para enfatizar más esos aspectos, se emplea una doble estrategia. Por un lado, la (...) analogía con la escuela marítima de la geopolítica y, por otro lado, el marco conceptual de la zona gris, al entender que la primera contribuye a la comprensión de la interrelación entre geoeconomía y geopolítica, y que el segundo es de muy probable aplicación a lo largo de los próximos años, por los motivos que se esgrimen en el artículo.

En este libro, el autor aborda el debate sobre lo opaco y lo transparente en relación con lo sagrado, especialmente desde la perspectiva de la interacción entre lo trascendente y lo inmanente. La "transparencia" es un valor en alza que responde a la aspiración del ciudadano moderno de controlar los gestores públicos. Sin embargo, al aplicarlo al ámbito religioso, surgen dificultades como la impenetrabilidad de un Misterio que, por definición, en incognoscible. La opinión de pensadores como Walter Benjamin, María Zambrano, (...) Friedrich Nietzsche, Simone Weil, Ludwig Wittgenstein y Byung-Chul Han, contrastada con las aportaciones del mundo del arte, con las fuentes bíblicas y con textos de tradición cristina, contribuye a clarificar los términos "trasparencia" y "opacidad" y a evitar explicaciones simplistas que obvian sus matices, sus polisemias y sus paradojas. A su vez, el debate sobre la transparencia nos ayuda a redefinir el marco conceptual que articula la relación entre inmanencia y trascendencia. El análisis de la peculiar opacidad de los trascendente permite atribuir un significado más profundo a lo transparente. Entonces, el Misterio abandona el dominio de lo opaco para darse a conocer transparentándose, de manera sutil, a través de lo inmanente. (shrink)

The doctor-patient relationship is a crucial aspect of primary-care practice Research on associations between quality of care provision and burnout and empathy in a primary care setting could improve this relationship. Cross-sectional study of family physicians and nurses of twenty-two primary care centers in the health district of Lleida, Spain. Empathy and burnout were measured using the Jefferson Physician Empathy Scale and the Maslach Burnout Inventory, while quality of care delivery was evaluated using Quality Standard Indicator scores. JPSE and MBI (...) results were grouped into low, medium, and high scores to analyze associations with QSI scores and sociodemographic variables. The mean QSI score recorded for the family physicians and nurses was 665. Higher, albeit insignificant, QSI scores were observed for practitioners with high burnout. No differences were observed according to level of empathy. The differences with respect to sex, age, and area of practice were not significant. Practitioners with low empathy had higher QSI scores than those with high empathy while those with high burnout had higher scores than those with low burnout. Burnout and empathy did not significantly influence quality of care delivery scores in 22 primary care centers. More studies, however, are needed to investigate the unexpected trend observed that suggests that physicians and nurses with higher levels of burnout provide higher quality care. (shrink)

Neste artigo, propõe-se uma leitura das categorias no tratado aristotélico homônimo como um primeiro esboço de uma ontologia regional, centrada nas substâncias sensíveis. Tendo por foco substância, quantidade, qualidade, relativo, agir e sofrer, este trabalho busca expor as duas estratégias principais que Aristóteles parece empregar para chegar a uma lista das categorias: (a) características básicas, cuja satisfação ou não satisfação de cada uma determina a natureza categorial de cada item e (b) a propriedade única que caracteriza cada categoria em contraste (...) com todas as outras. São, então, feitas considerações para vincular esse primeiro esboço ontológico a temas discutidos nos livros Lambda e Zeta da Metafísica, de modo a sugerir as direções principais que a sua ontologia nova (e geral) seguirá ao evoluir para uma teoria unificada da substância.

Al evaluar el papel que el mito cumple en el pensamiento griego antiguo, se debe distinguir, o al menos así se argumenta, el tipo de razón con la que se lo contrasta. En efecto, su función se altera cuando la razón es considerada monolíticamente o, como suele suceder en Aristóteles, cuando opera de dos modos: de modo práctico o de modo teórico. Desde esta última perspectiva, el mito vuelve a un lugar básico en la obra poética.

We discuss two key assumptions of Levelt et al.'s model of lexical retrieval: (1) the nondecompositional character of concepts and (2) lemmas as purely syntactic representations. These assumptions fail to capture the broader role of lemmas, which we propose as that of lexical–semantic representations binding (compositional) semantics with phonology (or orthography).

O'Brien & Opie argue that (1) only explicit representations give rise to conscious experience, and (2) explicit representations depend on stable patterns of activation. In neglect patients, the stimuli presented to the neglected hemifield are not consciously experienced but exert causal effects on the processing of other stimuli presented to the intact hemifield. We argue that O'Brien & Opie cannot account for a nonconscious representation that is stable, as attested by the fact that it affects behavior, but is neither potentially (...) explicit nor tacit.

Inspired by the literature on extended/scaffolded mind, a debate concerning the contribution of extra-bodily resources to our (extended) emotions is recently gaining traction. Within this debate, inspired by the literature on cognitive artifacts introduces the notion of “affective artifacts”, indicating those objects that exert persistent effects on our feelings, possibly altering our self. However, by focusing on feelings, this notion neglects other facets of emotional episodes. Following Scarnatino’s tripartition between feeling, appraisal, and motivational theories of emotion, I present three varieties (...) of affective artifacts: Feeling, Evaluative and Motivational Artifacts.

In this paper, I investigate the variety and richness of the taxonomical practices between the end of the nineteenth and the early twentieth centuries. During these decades, zoologists and paleontologists came up with different quantitative practices in order to classify their data in line with the new biological principles introduced by Charles Darwin. Specifically, I will investigate Florentino Ameghino’s mathematization of mammalian dentition and the quantitative practices and visualizations of several German-speaking paleontologists at the beginning of the twentieth century. In (...) so doing, this paper will call attention to the visual and quantitative language of early twentieth-century systematics. My analysis will therefore contribute to a prehistory of the statistical frame of mind in biology, a study which has yet to be written in full. Second, my work highlights the productive intertwinement between biological practices and philosophical frameworks at the turn of the nineteenth century. Deeply rooted in Kantian bio-philosophy, several biologists sought to find rules in order to apply ordering principles to chaotic taxonomic information. This implies the necessity to investigate the neglected role of Kantian and Romantic bio-philosophy in the unfolding of twentieth-century biology. (shrink)

Debates on situated affectivity have mainly focused on tools that exert some positive influence on affective experience. Far less attention has been paid to artifacts that interact with the expression of affect, or to those that exert some negative influence. To shed light on that shadowy corner of our affective social lives, I describe the workings of an atypical socio-affective artifact, namely, sunglasses. Drawing on insights from psychology and other social sciences, I construe sunglasses as a social shield that helps (...) us block spontaneous emotional expressions, as well as affecting other social processes that heavily depend on the eye region: gaze direction detection, identity recognition, and the sense of intimacy afforded by eye contact.

Between 1909 and 1913, Berlin’s Museum für Naturkunde unearthed more than 225 tons of fossils in former German East Africa and transported them to Berlin. Among them were the bones of Brachiosaurus brancai, which would eventually become the biggest mounted dinosaur in the world. By analyzing the social and communicative strategies that made this expedition possible, this paper aims to reveal several aspects of natural history knowledge production at the end of the long nineteenth century. Using rhetoric, the director of (...) the Geological–Paleontological Museum in Berlin, Wilhelm von Branca, conducted a highly successful campaign to market the dinosaurs in Prussia and to convince public opinion and the Prussian central state of the value of paleontology. He fired the Prussian imagination and took advantage of the competitive urge to emulate American paleontology and industry. This work examines how his public relations strategies shaped the German biological “landscape” of the first decades of the twentieth century. It asks: when and under what conditions did paleontology successfully appeal to the public? How does communication dictate, shape, and constrain the development of a specific epistemic agenda? And what kind of power do the public and money have? (shrink)

Proposition I.1 is, by far, the most popular example used to justify the thesis that many of Euclid’s geometric arguments are diagram-based. Many scholars have recently articulated this thesis in different ways and argued for it. My purpose is to reformulate it in a quite general way, by describing what I take to be the twofold role that diagrams play in Euclid’s plane geometry (EPG). Euclid’s arguments are object-dependent. They are about geometric objects. Hence, they cannot be diagram-based unless diagrams (...) are supposed to have an appropriate relation with these objects. I take this relation to be a quite peculiar sort of representation. Its peculiarity depends on the two following claims that I shall argue for: ( i ) The identity conditions of EPG objects are provided by the identity conditions of the diagrams that represent them; ( ii ) EPG objects inherit some properties and relations from these diagrams.

Debates on the moral status of human embryos have been highly and continuously controversial. For many, these controversies have turned into a fruitless scholastical endeavor. However, recent developments and insights in cellular biology have cast further doubt on one of the core points of dissent: the argument from potentiality. In this article we want to show in a nonscholastical way why this argument cannot possibly survive. Getting once more into the intricacies of status debates is a must in our eyes. (...) Not merely intellectual coherence but the standing and self-understanding of current stem cell research might profit from finally taking leave of the argument from potentiality. (shrink)

By inserting the dialogue between Einstein, Schlick and Reichenbach into a wider network of debates about the epistemology of geometry, this paper shows that not only did Einstein and Logical Empiricists come to disagree about the role, principled or provisional, played by rods and clocks in General Relativity, but also that in their lifelong interchange, they never clearly identified the problem they were discussing. Einstein’s reflections on geometry can be understood only in the context of his ”measuring rod objection” against (...) Weyl. On the contrary, Logical Empiricists, though carefully analyzing the Einstein–Weyl debate, tried to interpret Einstein’s epistemology of geometry as a continuation of the Helmholtz–Poincaré debate by other means. The origin of the misunderstanding, it is argued, should be found in the failed appreciation of the difference between a “Helmholtzian” and a “Riemannian” tradition. The epistemological problems raised by General Relativity are extraneous to the first tradition and can only be understood in the context of the latter, the philosophical significance of which, however, still needs to be fully explored.

The aim of this article is to contribute to understanding the changing role of government in promoting corporate social responsibility (CSR). Over the last decade, governments have joined other stakeholders in assuming a relevant role as drivers of CSR, working together with intergovernmental organizations and recognizing that public policies are key in encouraging a greater sense of CSR. This paper focuses on the analysis of the new strategies adopted by governments in order to promote, and encourage businesses to adopt, CSR (...) values and strategies. The research is based on the analysis of an explanatory framework, related to the development of a relational analytical framework, which tries to analyze the vision, values, strategies and roles adopted by governments, and the integration of new partnerships that governments establish in the CSR area with the private sector and social organizations. The research compares CSR initiatives and public policies in three European countries: Italy, Norway and the United Kingdom, and focuses on governmental drivers and responses. The preliminary results demonstrate that governments are incorporating a common statement and discourse on CSR, working in partnership with the private and social sectors. For governments, CSR implies the need to manage a complex set of relationships in order to develop a win–win situation between business and social organizations. However, the research also focuses on the differences between the three governments when applying CSR public policies. These divergences are based on the previous cultural and political framework, such as the welfare state typology, the organizational structures and the business and social and cultural background in each country.

In their attempt to connect the workings of the human mind with their neural realizers, cognitive neuroscientists often bracket out individual differences to build a single, abstract model that purportedly represents (almost) every human being’s brain. In this paper I first examine the rationale behind this model, which I call ‘Platonic Brain Model’. Then I argue that it is to be surpassed in favor of multiple models allowing for patterned inter-individual differences. I introduce the debate on legitimate (and illegitimate) ways (...) of mapping neural structures and cognitive functions, endorsing a view according to which function-structure mapping is context-sensitive. Building on the discussion of the ongoing debate on the function(s) of the so-called Fusiform “Face” Area, I show the necessity of indexing function-structure mappings to some populations of subjects, clustered on the basis of factors such as their expertise in a given domain.

We investigate the major mathematical theories of space from a modal standpoint: topology, affine geometry, metric geometry, and vector algebra. This allows us to see new fine-structure in spatial patterns which suggests analogies across these mathematical theories in terms of modal, temporal, and conditional logics. Throughout the modal walk through space, expressive power is analyzed in terms of language design, bisimulations, and correspondence phenomena. The result is both unification across the areas visited, and the uncovering of interesting new questions.

The aim of this article is to address the problem of what is usually called “self-consciousness” by studying Charles S. Peirce’s semeiotic treatment of self-referential statements. Peirce believes that an adequate study of the mind requires “to reduce all mental action,” including “self-consciousness,” “to the formula of valid reasoning” (W 2:214, EP 1:30, 5:267, 1868) and its semeiotic nature. While Peirce makes frequent use of the notion of “consciousness,” he is at the same time distant from the understanding of the (...) “conscious mind” that Descartes invented and made canonical (e.g., W 1:491, 1866), and which from the modern epoch stretches out to the contemporary discussion on, as David Chalmers put it, the “hard problem” of the mind. In what follows, I argue that Peirce puts forth a powerful theory of self-consciousness based on his semeiotic understanding of self-reference and indexicality. To the question, “How can we elucidate the phenomenon of self-consciousness?”, we should answer, with Peirce, “What we call self-consciousness corresponds to the practice of narratives and descriptions ultimately based on indexical self-referential statements, which are in turn rooted in very specific dimensions of human experience.” It is also important to underscore from the outset that the problem of indexical self-reference cannot be separated from Peirce’s concept of experience, which is one of the most interesting insights of Peirce’s philosophy and classical American pragmatism. In particular, it will be essential to see what are the experiential-perceptual conditions under which indexical self-referential statements can work as such. (shrink)

Reductionists in biology claim that all biological events can be explained in terms of genes and macromolecules alone, while antireductionists argue that some biological events must be explained at a higher level.

The analysis of molecular explanations herein carries an important philosophical implication; in shunning crude reductionism and extreme versions of holism, we can combine the (...) insights of thoughtful reductionists with sophisticated antireductionism. When this is done, the question of explanatory reductionism becomes less substantial than often supposed. (shrink)

Embodiment and embeddedness define an attractive framework to the study of cognition. I discuss whether theory of mind, i.e. the ability to attribute mental states to others to predict and explain their behaviour, fits these two principles. In agreement with available evidence, embodied cognitive processes may underlie the earliest manifestations of social cognitive abilities such as infants’ selective behaviour in spontaneous-response false belief tasks. Instead, late theory-of-mind abilities, such as the capacity to pass the (elicited-response) false belief test at age (...) four, depend on children’s ability to explain people’s reasons to act in conversation with adults. Accordingly, rather than embodied, late theory-of-mind abilities are embedded in an external linguistic practice. (shrink)

A previous observational study suggested that when faced with a partner with its back turned, chimpanzees tend to move around to the front of a non-attending partner and then gesture — rather than gesturing once to attract attention and then again to convey a specific intent. We investigated this preference experimentally by presenting six orangutans, five gorillas, nine chimpanzees, and four bonobos with a food begging situation in which we varied the body orientation of an experimenter with respect to the (...) subject and the location of the food. These manipulations allowed us to measure whether subjects preferred to move around to face E or to use signals to attract her attention before they begged for food. Results showed that all species moved around to face E and then produced visual gestures, instead of using tactile/ auditory gestures behind E to call her attention. Species differences were apparent particularly when the food and E were in different locations. Unlike gorillas and orangutans, chimpanzees and bonobos produced their gestures in front of E in all conditions, including that in which subjects had to leave the food behind to communicate with her. Implications of these results are discussed in the context of the evolution of social cognition in great apes. (shrink)

A standard approach to examining Deleuze's concept of difference in Difference and Repetition is to follow his critique of representation through an overturning of Platonism, which Deleuze finds to be the definitive task of philosophy after Nietzsche. While engaging this largely critical project, however, there is a tendency to overlook the dimensions of Platonism that Deleuze rehabilitates in a differential and immanent register. This paper aims to recover the essential dimensions of Platonism at the very heart of Deleuze's philosophy of (...) difference. This recovery is accomplished by distinguishing Nietzsche's overturning of Platonism through his evaluation of the reactive politics of the Idea from Deleuze's own reversal of Platonism through his evaluation of the active politics of simulacra.

The starting point of this essay is an article of Enzo Paci, “Prospettive relazionistiche” published in Dall’esistenzialismo al relazionismo, in which the author interprets Merleau-Ponty’s project in the light of a quotation from Saint Exupery: “Man is a knot of relations, and relations alone count for man.” The problem of relations plays, in fact, a central role in all of Merleau-Ponty’s work; hence the principal objective of this essay: to reflect on the originary value of relations in the constitution of (...) the human subject.As Merleau-Ponty himself suggests in his early reflection on affective life, everything in the human being is manifested under the form of the desire of life understood as relation. It is the affective dynamic of desire that provokes reason and configures a manner of being that, through the discovery of alterity, surpasses natural determinisms in opening us to the experience of freedom, sacrifice and love. It is by building on this originary relational constitution of existence that we re-read Merleau-Ponty’s philosophy, in particular the problem of the self as relation. This makes possible a renewed approach to the human sciences with the goal of thinking our relations with others. (shrink)

Computational models of meaning trained on naturally occurring text successfully model human performance on tasks involving simple similarity measures, but they characterize meaning in terms of undifferentiated bags of words or topical dimensions.

We present here a fully automatic method for extracting a structured and comprehensive set of concept descriptions directly from an English part‐of‐speech‐tagged corpus. Concepts are characterized by weighted properties, enriched with concept–property types that approximate classical (...) relations such as hypernymy and function. Our model outperforms comparable algorithms in cognitive tasks pertaining not only to concept‐internal structures (discovering properties of concepts, grouping properties by property type) but also to inter‐concept relations (clustering into superordinates), suggesting the empirical validity of the property‐based approach.

Meditation comprises a series of practices mainly developed in eastern cultures aiming at controlling emotions and enhancing attentional processes. Several authors proposed to divide meditation techniques in focused attention and open monitoring techniques. Previous studies have reported differences in brain networks underlying FA and OM. On the other hand common activations across different meditative practices have been reported. Despite differences between forms of meditation and their underlying cognitive processes, we propose that all meditative techniques could share a central process that (...) would be supported by a core network for meditation since their general common goal is to induce relaxation, regulating attention and developing an attitude of detachment from one’s own thoughts. To test this hypothesis, we conducted a quantitative meta-analysis based on activation likelihood estimation of 10 neuroimaging studies on different meditative techniques to evidence the core cortical network subserving meditation. We showed activation of basal ganglia , limbic system and medial prefrontal cortex . We discuss the functional role of these structures in meditation and we tentatively propose a neurocognitive model of meditation that could guide future research. (shrink)
