IL PROBLEMA POLITICO COME PROBLEMA PEDAGOGICO IN ANTONIO GRAMSCI

2008

Un'analisi del problema politico dell'egemonia gramsciana quale questione di ordine fondamentalmente pedagogico. Con capitoli in cui la figura di Gramsci viene interrelata a quelle di Althusser o Habermas.

Gramsci e i gruppi "ai margini della storia"

In vitro and in vivo investigations of osteogenic differentiation ability of dental pulp stem cells (DPSCs) and gingival mesenchymal stem cells (GMSC…

2020

Thanks to the use of human mesenchymal stem cells (hMSCs), smart biomaterials and active biomolecules, Regenerative Medicine (RM) and Bone Tissue Engineering (BTE) can restore structure and function of injured tissues. Among the different sources of hMSCs, the oro-facial hMSCs have promising in vitro and in vivo regeneration potential; in particular, dental pulp and gingiva are valuable sources of autologous hMSCs. The aim of this PhD thesis is testing the in vitro and in vivo bone regeneration ability of hMSCs isolated from dental pulp and inflamed gingiva of periodontally-compromised teeth, up to now considered biological waste tissues and discarded during surgical procedures, on two comm…

Quantifying the relationship between specialisation and reputation in an online platform

2022

AbstractOnline platforms implement digital reputation systems in order to steer individual user behaviour towards outcomes that are deemed desirable on a collective level. At the same time, most online platforms are highly decentralised environments, leaving their users plenty of room to pursue different strategies and diversify behaviour. We provide a statistical characterisation of the user behaviour emerging from the interplay of such competing forces in Stack Overflow, a long-standing knowledge sharing platform. Over the 11 years covered by our analysis, we represent the interactions between users and topics as bipartite networks. We find such networks to display nested structures akin …

Ultrametricity property of energy landscapes of multidisperse packing problems

2009

We consider the problem of finding the densest closed packing of hard disks with proposed different radii in a circular environment, such that the radius of the circumcircle is minimal. The subspace of the quasioptimum configurations of this problem exhibits the property of ultrametricity.

Infinite orbit depth and length of Melnikov functions

2019

Abstract In this paper we study polynomial Hamiltonian systems d F = 0 in the plane and their small perturbations: d F + ϵ ω = 0 . The first nonzero Melnikov function M μ = M μ ( F , γ , ω ) of the Poincare map along a loop γ of d F = 0 is given by an iterated integral [3] . In [7] , we bounded the length of the iterated integral M μ by a geometric number k = k ( F , γ ) which we call orbit depth. We conjectured that the bound is optimal. Here, we give a simple example of a Hamiltonian system F and its orbit γ having infinite orbit depth. If our conjecture is true, for this example there should exist deformations d F + ϵ ω with arbitrary high length first nonzero Melnikov function M μ along…

Regularization of perturbed state-dependent sweeping processes with nonregular sets

2018

International audience; In this paper, we prove the convergence strongly pointwisely (up to a subsequence) of Moreau-Yosida regularization of perturbed state-dependent sweeping process with nonregular (subsmooth and positively alpha-far) sets in separable Hilbert spaces. Some relevant consequences are indicated.

Singular quadratic Lie superalgebras

2012

In this paper, we give a generalization of results in \cite{PU07} and \cite{DPU10} by applying the tools of graded Lie algebras to quadratic Lie superalgebras. In this way, we obtain a numerical invariant of quadratic Lie superalgebras and a classification of singular quadratic Lie superalgebras, i.e. those with a nonzero invariant. Finally, we study a class of quadratic Lie superalgebras obtained by the method of generalized double extensions.
