A classical theoretical frame to interpret motor reactions to emotional stimuli is that such stimuli, particularly those threat-related, are processed preferentially, i.e., they are capable of capturing and grabbing attention automatically. Research has recently challenged this view, showing that the task relevance of emotional stimuli is crucial to having a reliable behavioral effect. Such evidence indicated that emotional facial expressions do not automatically influence motor responses in healthy young adults, but they do so only when intrinsically pertinent to the ongoing (...) subject’s goals. Given the theoretical relevance of these findings, it is essential to assess their generalizability to different, socially relevant emotional stimuli such as emotional body postures. To address this issue, we compared the performance of 36 right-handed participants in two different versions of a Go/No-go task. In the Emotional Discrimination task, participants were required to withhold their responses at the display of emotional body postures and to move at the presentation of neutral postures. Differently, in the control task, the same images were shown, but participants had to respond according to the color of the actor/actress’ t-shirt, disregarding the emotional content. Results showed that participants made more commission errors for happy than fearful body postures in the Emotional Discrimination task. However, this difference disappeared in the control task. Such evidence indicates that, like facial emotion, emotional body expressions do not influence motor control automatically, but only when they are task-relevant. (shrink)

The concept of living has changed in time along the history of biology and its specificity has been associated or to a particular matter, active such as the chemical one, or was considered as a product of the spatial organization of a passive matter. Today, these two paths can be merged in the chemical perspective that takes account of the general reflections on the complexity and on the systemic, in the “systemic complexity” approach.

The complexity of cognitive emulation of human diagnostic reasoning is the major challenge in the implementation of computer-based programs for diagnostic advice in medicine. We here present an epistemological model of diagnosis with the ultimate goal of defining a high-level language for cognitive and computational primitives. The diagnostic task proceeds through three different phases: hypotheses generation, hypotheses testing and hypotheses closure. Hypotheses generation has the inferential form of abduction (from findings to hypotheses) constrained under the criterion of plausibility. Hypotheses testing (...) is achieved by a deductive inference (from generated hypotheses to expected findings), followed by an eliminative induction, constrained under the criterion of covering, which matches expected findings against patient''s findings to select the best explanation. Hypotheses closure is a deductive-inductive type of inference very similar to the inferences operating in hypotheses testing. In this case induction matches the consequences of the generated hypotheses against the patient''s characteristics or preferences under the criterion of utility. By using the language exploited in this epistemological model, it is possible to describe the cognitive tasks underlying the most influential knowledge-based diagnostic systems. (shrink)

- Il saggio si propone di tracciare un bilancio del caso del Portogallo, dal 1996 uno dei pochi paesi dell'Unione Europea che nell'ambito del voto amministrativo attribuisce il diritto al voto e all'eleggibilitÀ ad alcuni cittadini extracomunitari, seppur con alcune limitazioni. Tenendo conto che nelle ultime tre tornate elettorali amministrative pochissimi stranieri sono risultati eletti nei consigli comunali, nelle giunte e nelle circoscrizioni, gli autori si interrogano sul grado di valorizzazione di cui ha goduto una simile innovazione legislativa, cercando di (...) comprendere anche il punto di vista delle diverse comunitÀ immigrate.

L’intento di questo articolo è di porre in luce come, all’interno della Critica della ragione dialettica temi quali Prassi, Materia e Destino siano in un necessario ed essenziale rapporto. Per fare emergere tale cooriginarietà, ci siamo serviti della parola “costituzione”, intendendo con questa non una qualche descrizione statica, quanto piuttosto il senso dinamico della Storia secondo una motilità particolare, l’errare.

The aetio-pathogenetic sequences and the physio-pathological patterns of diabetes, emphysema, cholera, circulatory shock and thrombosis have been analysed with respect to an evolutionary interpretation. The diseases, although reflecting alterations of processes that can always be described in physico-chemical language, occur only at the level of biological systems which reflects the decodification of genomic project: the teleonomic projects that have been developed during evolution. The concepts of evolutionary emergence and of downward causation have been used to discuss the relationship between the (...) molecular events responsible for the initiation of the disease, and the subsequent events responsible for the aetio-pathogenesis, for the systemic disarrangement and for the additional alterations of tissues and cells independent of the initial molecular events. In diabetes the systemic disarrangement, glycosuria and hyperglycemia, reflect the evolutionary emergence of the processes regulating carbohydrate metabolism, whereas the cardiovascular and neurological alterations are effects of the systemic disarrangement by a mechanism of downward causation. The complexity of the aetio-pathogenesis and of the physio-pathological patterns of diseases is due to the generation of information during the evolution of multi-hierarchical entities. The evolutionary epistemology approach is useful to explain the behaviour of complex systems. (shrink)

The discourse on escaping is primarily directed towards the who of escape. The question of what and how of escaping in its cultural-anthropological significance is usually neglected. The present paper claims to overcome this inadequacy by exploring escape eo ipso and as a spatial-theoretical phenomenon. For this purpose, it is necessary to rethink escape as a triple articulated phenomenological topology based on three vectors: escape as a start, escape as a transition and escape as a destination/refuge. The escape-vectors play the (...) role of symbolic and basic structures which are connected with linguistic and cognitive paradigms. Among the basic figures of escaping, this paper examines escape as a separation, as a non-place and as a fugue; these correspond in turn to the environmental metaphors, first, of the earth as exile, secondly, of the sea and the desert, and finally of the earth as asylum. The multilayered topology of escaping is reconstructed in the interdisciplinary field of spatial theory, of etymology, literature and political philosophy. By examining its spatial-philosophical characteristics, escape emerges as a dynamic phenomenon that can reshape essential concepts and inverse traditional categories of politics. For that reason, escaping determines a philosophically “inverted world” and consequently constitutes an essential source for the future development of cultural-political systems. (shrink)

Simone Weil non ha grande considerazione del diritto e non v’è dubbio che questa considerazione sia contraccambiata dai giuristi. In effetti, la Weil ha una concezione troppo severa verso istituzioni che sono fondamentali per il funzionamento della democrazia –i partiti politici– ed ha una visione del diritto che è troppo schiacciata sulla forza per destare l’attenzione dei giuristi. Ciò nonostante, leggere la Weil da una prospettiva giuridica non è affatto privo di interesse: i suoi scritti hanno anticipato molte vicende del (...) costituzionalismo del secondo dopoguerra come, ad esempio, il tramonto della legge generale ed astratta e la crescita di importanza dei giudici; essi, inoltre, offrono degli utili spunti di riflessione –sia critici che costruttivi– su temi che oggi sono all’ordine del giorno in ambito filosofico-giuridico, come l’uso retorico dei diritti e l’attenzione agli obblighi di giustizia sociale.

In some of his philosophical and scientific works Charles S. Peirce emphasized the economic constraints put upon scientific research. The process of generation, selection and testing of hypotheses, as well as the collection of data and information, is subject to time and resource constraints. Working scientists must individuate the most promising hypotheses and lines of research given the amount of resources at disposal. To this effect they have to estimate in particular the resources needed for testing, and what the acceptability (...) standards require. To put this into economic terms, they have to estimate the expected benefits of research compared with its expected costs. Those who allocate research funds... (shrink)
