OSSERVAZIONI SULLA FORTUNA E I FRAINTENDIMENTI DEL TRACTATUS LOGICO-PHILOSOPHICUS A CENT’ANNI DALLA SUA PUBBLICAZIONE
2022
Starting with a suggestion, the similarity between Wittgenstein and Montaigne, this article reconstructs a quick history of the substantial misunderstanding that, despite his enormous success, characterized the "Tractatus logico-philosophicus" and the role of ethical issue in this book.
Vibronic Model for Intercommunication of Localized Spins via Itinerant Electron
2019
In this article, we propose a vibronic pseudo Jahn–Teller model for partially delocalized mixed-valence molecules aimed to describe the magnetic coupling between the localized spins mediated by the delocalized electron. The simplest partially delocalized system that retains the main studied features is assumed to consist of a one-electron mixed-valence dimer, which is connected to the two terminal magnetic ions. The model involves the following key interactions: electron transfer in the spin-delocalized subsystem of a mixed-valence molecule, which is mimicked by a dimeric unit, coupling of the itinerant electrons with the molecular vibrations, and isotropic magnetic exchange between the loc…
On finite groups with many supersoluble subgroups
2017
[EN] The solubility of a finite group with less than 6 non-supersoluble subgroups is confirmed in the paper. Moreover we prove that a finite insoluble group has exactly 6 non-supersoluble subgroups if and only if it is isomorphic to A5 or SL2 (5). Furthermore, it is shown that a finite insoluble group has exactly 22 non-nilpotent subgroups if and only if it is isomorphic to A5 or SL2 (5). This confirms a conjecture of Zarrin (Arch Math (Basel) 99:201 206, 2012).
Taxonomic Classification for Living Organisms Using Convolutional Neural Networks
2017
Taxonomic classification has a wide-range of applications such as finding out more about evolutionary history. Compared to the estimated number of organisms that nature harbors, humanity does not have a thorough comprehension of to which specific classes they belong. The classification of living organisms can be done in many machine learning techniques. However, in this study, this is performed using convolutional neural networks. Moreover, a DNA encoding technique is incorporated in the algorithm to increase performance and avoid misclassifications. The algorithm proposed outperformed the state of the art algorithms in terms of accuracy and sensitivity, which illustrates a high potential f…
The language game of lost meaning: Using literal meaning as a metalinguistic resource
2019
AbstractBy literal meaning (LM) we usually refer to a theoretical notion which is at the center of a big debate involving philosophers and linguists with various orientations. At the same time, LM is rooted in a linguistic intuition of the speaker, which we could formulate as follows: words taken in isolation have a meaning. Adopting this general take on LM, we are using a notion of LM that seems incompatible with any research program of a contextualist type; I will show, instead, that in a radically contextualist (and Wittgensteinian) perspective, this notion of LM can have legitimate circulation in particular types of language games. I will propose a recovery of the notion of LM saving th…
In nomine patris: Discursive strategies and ideology in the Cosa Nostra family discourse
2017
Abstract The article investigates how Cosa Nostra family discourse is characterized by a series of discursive strategies that give shape to specific ideological structures. By analysing a TV interview to the son of Bernardo Provenzano, boss of Cosa Nostra, it is possible to understand how the criminal values and practices are maintained and reproduced within the father–son relationship. Specifically, we show how the son justifies, legitimises or denies the criminal actions of his father. The ideology of Cosa Nostra seems to be based on the inter-generational cultural continuity of its members, on the family as main locus of adherence, reductionism of its mediatic image, amoralism as father–…
La saisie esthétique, transformation non narrative de la subjectivité
2017
Abstract Post-Greimassian semiotics has worked toward a return to phenomenology, with the aim of studying the sensorial dimension and the body. Most of this research, however, has all but forgotten Greimas’s last book, De imperfection (1987), in which he proposes an original version of Merleau-Ponty’s philosophy with the notion of the aesthetic grasp. I propose to reconsider this almost abandoned notion, both from a theoretical point of view (a new version of the catharsis of philosophical aesthetics) and from the vantage of textual descriptions (the short story “The Naked Bosom” by Italo Calvino and the movie Ratatouille).
ABDUCTIVE INFERENCES IN PRAGMATIC PROCESSES
2018
Abstract In pragmatic theories, the notion of inference plays a central role, together with the communicative act in which it is activated. Although some scholars, such as Levinson, Sperber and Wilson, propose detailed and accurate analyses of this notion, we will maintain that these analyses can be better systematized if seen through Peirce’s notion of abduction. We will try to maintain that the variety of inferential processes in play in a linguistic act is mostly of an abductive nature. Moreover, we will maintain that the typological tripartition of abductions discussed by Eco (1981) allows to account for a signi cant part of the mechanisms involved in the comprehension of an utterance, …
Maximal subgroups and PST-groups
2013
A subgroup H of a group G is said r to permute with a subgroup K of G if HK is a subgroup of G. H is said to be permutable (resp. S-permutable) if it permutes with all the subgroups (resp. Sylow subgroups) of G. Finite groups in which permutability (resp. S-permutability) is a transitive relation are called PT-groups (resp. PST-groups). PT-, PST- and T-groups, or groups in which normality is transitive, have been extensively studied and characterised. Kaplan [Kaplan G., On T-groups, supersolvable groups, and maxmial subgroups, Arch. Math. (Basel), 2011, 96(1), 19-25)] presented some new characterisations of soluble T-groups. The main goal of this paper is to establish PT- and PST-versions o…
Passions animales
2021
In this article, questions concerning the relationship between semiotics and ethology will be discussed, starting from the idea of internaturality circulating in contemporary culture. After outlining the principles of a zoosemiotic 2.0, a case of animism present in the current press will be analysed, which speaks of the passions of apes as typically human passions.
