In this article, I analyse line-rendering techniques in drawing and choreography, based on a Deleuzian framework. This pragmatic approach for understanding affect emerges in three distinct formulations. The first engages the coincidence of drawing and choreography at the limit of reach; the second investigates how trace and movement generate different yet mutually resonant versions of semblance. The third framework considers the potential for improvisation in the irreconcilability of contour and surface in the weighted line. These three framings generate an experimental (...) milieu in which I articulate the co-emergence of thought and feeling in relation to relevant concepts of the body and affect. In activating affective intensity in different line-rendering operations, this analysis traces the way that affects help to modulate tendencies of moving, feeling and thinking over a series of operations.

Créativité et mathématiques ne font pas bon ménage dans l'inconscient collectif. Pourtant à l'heure d'Internet, il existe bien une manière de revisiter la géométrie, l'algèbre ou même la logique. Il suffit de prendre un peu de distance par rapport aux calculs, de se donner quelques libertés par rapport à l'histoire, de changer de point de vue... En vagabondant à travers l'histoire et l'application des mathématiques, les auteurs se livrent ici à un jeu de vulgarisation d'une saveur et d'une subtilité inédites. (...) [4e de couv.]. (shrink)

Davidson's anomalous monism, his argument for the identity between mental and physical event tokens, has been frequently attacked, usually demanding a higher degree of physicalist commitment. My objection runs in the opposite direction: the identities inferred by Davidson from mental causation, the nomological character of causality and the anomaly of the mental are philosophically problematic and, more dramatically, incompatible with his famous argument against the third dogma of empiricism, the separation of content from conceptual scheme. Given the anomaly of the (...) mental and the absence of psychophysical laws, there are no conceptual resources to relate mental and physical predicates. We fall in the third dogma if we claim that the very same token event is mental and physical. One of the premises must be rejected: I will claim that we do not need a law to subsume cause and effect to be entitled to speak of causation. Davidson has never offered an argument to back this premise. Against such a dogma I will sketch some ideas pointing towards a different conception of causality, singularist and undetachable from explanatory practices. (shrink)

In this paper we consider an intuitionistic variant of the modal logic S4 (which we call IS4). The novelty of this paper is that we place particular importance on the natural deduction formulation of IS4— our formulation has several important metatheoretic properties. In addition, we study models of IS4— not in the framework of Kirpke semantics, but in the more general framework of category theory. This allows not only a more abstract definition of a whole class of models but also (...) a means of modelling proofs as well as provability. (shrink)

There is disagreement in the literature about the exact nature of the phenomenon of empathy. There are emotional, cognitive, and conditioning views, applying in varying degrees across species. An adequate description of the ultimate and proximate mechanism can integrate these views. Proximately, the perception of an object's state activates the subject's corresponding representations, which in turn activate somatic and autonomic responses. This mechanism supports basic behaviors that are crucial for the reproductive success of animals living in groups. The Perception-Action Model, (...) together with an understanding of how representations change with experience, can explain the major empirical effects in the literature. It can also predict a variety of empathy disorders. The interaction between the PAM and prefrontal functioning can also explain different levels of empathy across species and age groups. This view can advance our evolutionary understanding of empathy beyond inclusive fitness and reciprocal altruism and can explain different levels of empathy across individuals, species, stages of development, and situations. Key Words: altruism; cognitive empathy ; comparative; emotion; emotional contagion; empathy ; evolution; human; perception-action; perspective taking. (shrink)

Nowadays many debates are going on that relate to the agricultural and food sector. It looks as if present technological and organizational developments within the agricultural and food sector are badly geared to societal needs and expectations. In this article we briefly present a toolkit for moral communication within the food chain. This toolkit is developed as part of a European research project. Next, we discuss what such a toolkit can bring about, given the characteristics of the present day agricultural (...) and food sector and its wider context. We defend that the toolkit can be seen as one of the mechanisms that can help enterprises in the agricultural and food sector to be accountable. It should, however, be complemented with other mechanisms, first, to empower the wider public and, second, to stimulate a dialogue, on a more equal footing, between public authorities, citizens, and economic actors.

— We prescnt here a comparative study on the decay of chlorophyll a fluorescence yield in thylakoid membranes and photosystem 11 ‐enriched samples, measured with multifrequency cross‐correlation phase fluorometry. These measurements confirm the general conclusions of Van Mieghem ef al., obtained with a flash method, on the effects of reduction of the primary quinone acceptor on ChI a fluorescence yield of PSI. Different states of the reaction centers of PSII were produced by: pretreatment with sodium dithionite and mcthyl viologen followed (...) by laser illumination: the doubly reduced QA centers: with laser illumination or pretreatment with diuron: QA‐ centers; and the addition of micromolar concentration of dichlorobenzoquinonc : oxidized QA centers. The data were analyzed with Lorentzian distribution as well as with multiexponential fluorescence decay functions. The analysis with Lorcntzian distribution function showed that upon formation of QA. the major lifetime distribution peak shifted to longer lifetimes: from 0.25 ns to 1.66 ns and from 0.24 ns to 1.31 ns. However, when QAHZ was formed, the lifetime distribution peaks shifted back to shorter lifetimes both in thylakoids and PSIl membranes. Multiexponential analysis showed three lifetime components: fast, middle and slow. When QA was formed in PS11 centers, the amplitude of the fast Component decreased, but both thc amplitude and the lifetime of the middle component increased severalfold. However, when QA was doubly reduccd, the amplitude of the fast component increased and the amplitude of the middle component decreased: in addition, the lifetime of the slow component increased. All of the above results are consistent with the conclusions that PS11 charge separation is decreased when QA is formed and increased when doubly reduced QA is formed.

Morality is often defined in opposition to the natural "instincts," or as a tool to keep those instincts in check. New findings in neuroscience, social psychology, animal behaviour, and anthropology have brought us back to the original Darwinian position that moral behaviour is continuous with the social behavior of animals, and most likely evolved to enhance the cooperativeness of society. In this view, morality is part of human nature rather than its opposite. This interdisciplinary volume debates the origin and working (...) of human morality within the context of science as well as religion and philosophy. Experts from widely different backgrounds speculate how morality may have evolved, how it develops in the child, and what science can tell us about its working and origin. They also discuss how to deal with the age-old facts-versus-values debate, also known as the naturalistic fallacy. The implications of this exchange are enormous, as they may transform cherished views on if and why we are the only moral species. (shrink)

In recent years, functional connectivity in the developmental science received increasing attention. Although it has been reported that the anatomical connectivity in the preterm brain develops dramatically during the last months of pregnancy, little is known about how functional and effective connectivity change with maturation. The present study investigated how effective connectivity in premature infants evolves. To assess it, we use EEG measurements and graph-theory methodologies. We recorded data from 25 preterm babies, who underwent long-EEG monitoring at least twice during (...) their stay in the NICU. The recordings took place from 27 weeks postmenstrual age until 42 weeks PMA. Results showed that the EEG-connectivity, assessed using graph-theory indices, moved from a small-world network to a random one, since the clustering coefficient increases and the path length decreases. This shift can be due to the development of the thalamocortical connections and long-range cortical connections. Based on the network indices, we developed different age-prediction models. The best result showed that it is possible to predict the age of the infant with a root mean-squared error equal to 2.11 weeks. These results are similar to the ones reported in the literature for age prediction in preterm babies. (shrink)

This paper analyses the way in which discourse and argumentation may vary depending on participants’ educational level and gender. Men and women from three different educational levels (literacy, advanced level and university students) participated in discussion groups that debated about women and work, the sharing of housework and the way in which girls and boys are educated. The results showed important differences depending on participants’ educational level and gender. In general, the main differences were related to educational level, while gender (...) tended to interact with educational level, as a moderating factor. (shrink)

This essay attempts to retrieve the notion of ‘common sense’ within the writings of Descartes and Montaigne. I suggest that both writers represent distinct traditions in which the notion is employed. Descartes represents a modernist tradition in which common sense is understood to be a cognitive faculty, while Montaigne represents a humanist tradition in which common sense is understood as a political virtue. I also suggest that both writers work with the notion as a way of responding to diversity in (...) the world. The paper concludes with a discussion of how the notion of common sense employed by Descartes and Montaigne emerges out of the scholastic tradition and the assertion that both writers are responding to the educational consequences of scholasticism. I also discuss how the reconstruction of Descartes in this paper can provide some ground for raising new questions about the Cartesian project and educational philosophy. Finally, I gesture toward the idea that the humanist tradition with its understanding of common sense as political virtue can provide benefit for contemporary responses to diversity. (shrink)

In 1999, da Silva, D'Ottaviano and Sette proposed a general definition for the term translation between logics and presented an initial segment of its theory. Logics are characterized, in the most general sense, as sets with consequence relations and translations between logics as consequence-relation preserving maps. In a previous paper the authors introduced the concept of conservative translation between logics and studied some general properties of the co-complete category constituted by logics and conservative translations between them. In this paper we (...) present some conservative translations involving classical logic, Lukasiewicz three-valued system L3, the intuitionistic system I1 and several paraconsistent logics, as for instance Sette's system P1, the D'Ottaviano and da Costa system J3 and da Costa's systems Cn, 1≤ n≤ω.
