This paper presents a case study of the “electric hypothesis” of the causes of earthquakes, which emerged in the second half of the eighteenth century as part of the first studies of seismology. This hypothesis was related to Franklin’s views on atmospheric electricity and developed in a period when electric phenomena were widely studied, and was essentially based on solid empirical evidence and confirmed by model experiments. Even though it resulted from scientific reasoning, the theory remained strongly empirical, and was (...) supported by Italian scholars who were familiar with seismic events. Among these, Giuseppe Saverio Poli, a follower of Franklin, was able to provide a careful and comprehensive explanation of the disastrous earthquake of 1783, which occurred in Calabria, a region of southern Italy, and the St. Anne earthquake of 1805, by drawing not just upon the electric evidence, but all the relevant phenomenology available. We outline here the emergence, the development, and the later evolution (up to the beginning of the nineteenth century) of the “electric earthquake” paradigm by focusing on different works by Poli, including a previously unknown manuscript containing a thorough account of the Calabria earthquake prepared by the Neapolitan scholar for the Royal Society. The present case study therefore offers the opportunity to illustrate how electrical science shaped earthquake science to a degree not usually appreciated in the literature, and is also supported to some extent by the transition from Enlightenment scientific ideals to the Romantic conception of unity in the natural world, in search of common causes among phenomena belonging to different fields.

Decoherence is one of the most serious drawback in quantum mechanical applications. We discuss the effects of noise in superconducting devices (Josephson junctions) and suggest a decoherence-control strategy based on the quantum Zeno effect.

Objectives: Investigate and identify the relationship between physical exercise and cognitive performance measured by using different cognitive tests taken from Cambridge Brain Science.Methods: Thirty subjects, divided into two groups, undergo twelve cognitive tests from CBS. A comparison between the pre- and post-exercise results in terms of cognitive performance differences is carried out. Regression analysis between Heart Rate Variability features and CBS tests results is performed.Results: In most CBS tests, there is an improvement, or at least a confirmation, of the subject's (...) cognitive ability, for both groups. Reasoning, concentration, and planning tests seem to undergo critical positive changes. The regression analysis, performed by using a set of different algorithms, has demonstrated that it is possible, by monitoring the HRV during the exercise, to predict to some extent the cognitive performance, i.e., the CBS tests results. The best performing regression algorithms are Simple Linear and REPTree. The statistical analysis has proved that physical activity is statistically useful for the subjects in improving their cognitive performance.Conclusions: This study has numerically appraised the improvement, the conservation, or the worsening on different aspects of cognition. The found mathematical relationship between physical exercise and cognitive performance suggests that it is possible to predict the beneficial effect of various exercises on executive and attentive control.

In this paper we investigate whether, and how, corporate management strategically uses disclosure to manage the perceptions of different organizational audiences. In particular, we examine the interactions between the FIAT Group and three of its key organizational audiences—the local press, the international press, and the financial analysts, which are characterized by different levels of salience for the company. We focus on both how management reacts to the optimism level existing within each audience and how the narrative disclosure tone adopted by (...) FIAT influences the ex-post optimism in the local and international press or in the financial analyst community. We investigate the disclosure of the FIAT Group over a 6-year period , during which 70 price-sensitive press releases were published. On the basis of 1,887 news articles published in Italian newspapers and 411 analyst reports, we report evidence of different strategic patterns in the interaction processes between FIAT and its audiences. Our findings also indicate some differences in the way FIAT is affected by, and in turn, affects the sentiment of each audience, thus highlighting that the salience of the stakeholder is an important driver of the adoption of impression management techniques. Taken together, our findings point to issues related to setting the “tone at the top” and potential ethical matters. (shrink)

This Research Topic aimed at deepening our understanding of the levels and explanations that are of interest for cognitive sci- entists, neuroscientists, psychologists, behavioral scientists, and philosophers of science. Indeed, contemporary developments in neuroscience and psy- chology suggest that scientists are likely to deal with a multiplicity of levels, where each of the different levels entails laws of behavior appropriate to that level (Berntson et al., 2012). Also, gathering and modeling data at the different levels of analysis is not suffi- (...) cient: the integration of information across levels of analysis is a crucial issue. Given such state of affairs, a number of interesting questions arise. How can the autonomy of explanatory levels be properly understood in behavioral explanation? Is reductionism a satis- factory strategy? How can high-level and low-level models be constrained in order to be actually explanatory of both behav- ioral and neurological or molecular evidence? What is the kind of relationship between those models? (shrink)

This paper investigates how Merleau-Ponty and Simondon conceived the theory of information and, in particular, assessed its validity as an instrument of analysis in multiple fields of knowledge. Specifically, the comparison will analyze the relationship between organism and environment, which is central both to Merleau-Ponty’s philosophy of nature and to Simondon’s theory of individuation. For both authors, the analysis of processes of interaction between organism and environment is characterized by the search for a type of causality that distinguishes itself from (...) mechanism, which reduces these interactions to a sum of independent parts occasionally tied by a causally determined relation. However, while Merleau-Ponty views the categories introduced by the theory of information as a mere reconstruction of the mechanistic perspective, Simondon revises these categories to overcome mechanism and move towards the construction of a model of experience based on relation.

The relation between Garin and Cassirer is still an insufficiently investigated topic, here proposed also in light of their personal connections and documents. This relation represents an important episode in the Nachwirkung of Cassirer in Italy. Garin was deeply influenced by Cassirer’s historical research and philosophical thought, in the shaping of his own research fields and in the methodological debates about the history of philosophy.

The recent in vitro derivation of gamete‐like cells from mouse embryonic stem (mES) cells is a major breakthrough and lays down several challenges, both for the further scientific investigation and for the bioethical and biolegal discourse. We refer here to these cells as gamete‐like (sperm‐like or oocyte‐like, respectively), because at present there is still no evidence that these cells behave fully like bona fide sperm or oocytes, lacking the fundamental proof, i.e. combination with a normally derived gamete of the opposite (...) sex to yield a normal individual. However, the results published so far do show that these cells share some defining features of gametes. We discuss these results in the light of the bioethical and legal questions that are likely to arise would the same process become possible with human embryonic stem (hES) cells. (shrink)

The quantum Zeno effect is often studied and understood in term of nonunitary evolutions, involving projections à la von Neumann (measurements). We propose a dynamical explanation of this effect, which involves only unitary operators. The limit of infinitely frequent measurements is critically discussed: it is unphysical, yet interesting and peculiar.

The links between the philosophies of Montaigne and Bruno are explored here for the first time, in this speculative comparison that focuses as much on rhetoric and ethics as on ontology and anthropology.

Giordano Bruno's philosophical feat consists in the definition of a transformational force proper to human nature, which underlines its radical integration in the infinite cosmos.

S'il est vrai que le XVIe siècle italien, ou Cinquecento, correspond à une affirmation extraordinaire des pouvoirs de l'image, il est également incontestable que cette profusion s'accompagne d'une stratification théorique réunissant, par exemple, la théologie et la philosophie, la magie naturelle et la morale, la médecine et la politique. Peut-on définir un fil directeur dans cette diversité thématique? Peut-on définir une "unité systématique" ou une homogénéité, permettant de mettre en évidence la spécificité de la notion et de la pratique de (...) l'image à la Renaissance, ou bien faut-il accepter l'hétérogénéité des perspectives? C'est de telles questions que part l'auteur pour interroger la pensée de Renaissance, en construisant une cartographie des images à partir d'un corpus d'auteurs précis : Nicolas de Cues, Marsile Ficin, Pic de la Mirandole, Le Tasse, Giordano Bruno. Au terme du parcours, qui implique un réexamen d'ouvrages majeurs comme les Essais d'iconologie de Panofsky, Devant l'image de Georges Didi-Huberman et Pouvoirs de l'image de Louis Marin, il apparaît que la différence des approches et des questions traitées n'empêche pas de déterminer une vision d'ensemble dans la pensée de la Renaissance.

Cet ouvrage interroge le sens de la relation entre lien magique et métamorphose en essayant de dégager des perspectives philosophiques et politiques spécifiques à la Renaissance et à l'âge classique. La pensée de Giordano Bruno demeure dans cette optique une référence essentielle. Le philosophe nolain n'a de cesse de réfléchir sur le sens de cette relation, puisque c'est à travers elle qu'il construit aussi bien l'art de la mémoire que la pratique magique comme art du lien. Des thèmes comme celui (...) de la fureur héroïque, de la différence entre l'homme et l'animal, de l'action magique ne sont compréhensibles qu'à partir de la relation constitutive entre le lien et la métamorphose. C'est par conséquent en étudiant les "liens de la métamorphose" que l'on peut faire apparaître la constitution d'un spectre de savoirs (magie, philosophie, politique) traversant l'histoire européenne de la Renaissance et de l'âge classique. Cela permet également d'insister sur le rapport que ces savoirs entretiennent avec les pratiques sociales. La philosophie et la magie, loin d'apparaître comme des savoirs abstraits et purement nominaux, s'affirment en réalité comme des discours performatifs légitimant la constitution des liens civils et sociaux. Il s'agit en définitive ici de reconstituer à nouveaux frais des séquences historiques et philosophiques qui tracent les relations entre une sphère des savoirs et une pratique de l'institution du social, dans une perspective comprenant aussi bien des auteurs de la Renaissance (Machiavel, Giordano Bruno) que de l'âge classique et baroque (Hobbes, Graciân)."--Page 4 of cover.
