A note on a result of Guo and Isaacs about p-supersolubility of finite groups
2016
In this note, global information about a finite group is obtained by assuming that certain subgroups of some given order are S-semipermutable. Recall that a subgroup H of a finite group G is said to be S-semipermutable if H permutes with all Sylow subgroups of G of order coprime to . We prove that for a fixed prime p, a given Sylow p-subgroup P of a finite group G, and a power d of p dividing such that , if is S-semipermutable in for all normal subgroups H of P with , then either G is p-supersoluble or else . This extends the main result of Guo and Isaacs in (Arch. Math. 105:215-222 2015). We derive some theorems that extend some known results concerning S-semipermutable subgroups.
On the supersoluble hypercentre of a finite group
2016
[EN] We give some sufficient conditions for a normal p-subgroup P of a finite group G to have every G-chief factor below it cyclic. The S-permutability of some p-subgroups of O^p(G)plays an important role. Some known results can be reproved and some others appear as corollaries of our main theorems.
On self-normalising subgroups of finite groups
2010
[EN] The aim of this paper is to characterise the classes of groups in which every subnormal subgroup is normal, permutable, or S-permutable by the embedding of the subgroups (respectively, subgroups of prime power order) in their normal, permutable, or S-permutable closure, respectively.
On a graph related to permutability in finite groups
2010
For a finite group G we define the graph $\Gamma(G)$ to be the graph whose vertices are the conjugacy classes of cyclic subgroups of G and two conjugacy classes $\{\mathcal {A}, \mathcal {B}\}$ are joined by an edge if for some $\{A \in \mathcal {A},\, B \in \mathcal {B}\, A\}$ and B permute. We characterise those groups G for which $\Gamma(G)$ is complete.
CREATURA COLLETTIVA. NOTE SUL CONCETTO DI COGNIZIONE DISTRIBUITA
2012
In this paper, I will examine some aspects of a research program called “Distributed Cognition”. My goal is twofold: a) to clarify the many meanings of the word “distribution” in the context of cognitive science; b) to analyze the relationship between “Distributed co- gnition”andthreedistincttopicsi.e:1)“ComputationalTheoryofMind”;2)“SocialCognition”;3)“PersonalMind”.Inthe conclusions,I will try to fomulate some questions that remain open in the debate on Distributed Cognition.

Paolozzi & Wittgenstein: The Artist and the Philosopher
2019
Conceived as a collection of essays, this edited volume exceptionally brings together philosophers and art historians of different geographic and generational backgrounds to discuss Wittgenstein and Paolozzi, giving voice to a variety of disciplinary approaches and shaping diverse topics that may arouse the interest of a twofold audience. As a matter of fact, the book offers both a unique take on Paolozzi’s oeuvre, reassessing his pivotal importance in the second half of the twentieth century—especially as far as medium diversity and the use of popular culture are concerned—and a convenient opportunity to explore Wittgenstein’s thought related to visual arts and his influence on contemporar…
A Multisite Preregistered Paradigmatic Test of the Ego-Depletion Effect
2021
We conducted a preregistered multilaboratory project ( k = 36; N = 3,531) to assess the size and robustness of ego-depletion effects using a novel replication method, termed the paradigmatic replication approach. Each laboratory implemented one of two procedures that was intended to manipulate self-control and tested performance on a subsequent measure of self-control. Confirmatory tests found a nonsignificant result ( d = 0.06). Confirmatory Bayesian meta-analyses using an informed-prior hypothesis (δ = 0.30, SD = 0.15) found that the data were 4 times more likely under the null than the alternative hypothesis. Hence, preregistered analyses did not find evidence for a depletion effect. Ex…
