Understanding political violence: a criminological analysis
No full textUnderstanding Political Violence introduces political violence in the context of sociological and criminological debates. The author distinguishes between political violence from below, for example collective violence, insurgency, armed struggle and terrorism; and political violence from above, which includes indiscriminate repression, institutional and state violence, torture and war. Vincenzo Ruggiero discusses and critiques the contribution of criminological theory to understanding political violence. He draws on stimulating case studies to illustrate the theory, including interviews with former members of the Red Army Faction in Germany and the Brigate Rosse in Italy.The concluding chapter examines the recent development of a criminology of war and calls for a general ceasefire and the criminalisation of war, the most extreme form of institutional violence.This is essential reading for students and researchers in criminology, political studies, sociology, and war and conflict studies.
This book, published in 2006, is now available in Italian and a Spanish and a Russian edition will soon be available

Ruggiero: un trovatello, ma di famiglia illustre
No full textThis paper sets out some considerations about Ariosto’s Ruggiero. In the first part, the author discusses some ambiguities that apparently interfere with Ruggiero’s effectiveness as an encomiastic figure. In particular, the focus is on Saint John’s speech in the moon episode (Orlando Furioso, XXXV) and on Ruggiero’s exemplarity. In the second part, the author compares Ruggiero’s story with the hero pattern as analysed by the psychoanalyst Otto Rank. As a result, the connections between Ruggiero and the traditional aristocratic ideology are highlighted, also through a parallel with Machiavelli’s Life of Castruccio Castracani
Philosophical premises
No full textTaken from Il ritorno alla ragione (1946), this late essay marks a further decisive break between de Ruggiero and Croce. Drawing on Nietzsche, de Ruggiero argues that nineteenth-century German historicism resulted in disengagement from and indeed ambivalence with respect to the present. He goes on to argue that while Croce’s more sophisticated version of historicism provided a valuable bulwark against the encroachments of ‘irrationalism’ in the Fascist period, it also encouraged the rejection of the idea of any permanent, universal values whatsoever. Against Croce’s objections, de Ruggiero argues that the best insights of historicism should be incorporated into a return to Enlightenment reason and a ‘moving synthesis’ of immanence and transcendence
Inexact Bregman iteration with an application to Poisson data reconstruction
No full textThis work deals with the solution of image restoration problems by an
iterative regularization method based on the Bregman iteration. Any iteration of this
scheme requires to exactly compute the minimizer of a function. However, in some
image reconstruction applications, it is either impossible or extremely expensive to
obtain exact solutions of these subproblems. In this paper, we propose an inexact
version of the iterative procedure, where the inexactness in the inner subproblem
solution is controlled by a criterion that preserves the convergence of the Bregman
iteration and its features in image restoration problems. In particular, the method
allows to obtain accurate reconstructions also when only an overestimation of the
regularization parameter is known. The introduction of the inexactness in the iterative
scheme allows to address image reconstruction problems from data corrupted by
Poisson noise, exploiting the recent advances about specialized algorithms for the
numerical minimization of the generalized Kullback–Leibler divergence combined with
a regularization term. The results of several numerical experiments enable to evaluat

Abstract
We apply the theory of quantum generalized hydrodynamics (QGHD) introduced in (2020 Phys. Rev. Lett. 124 140603) to derive asymptotically exact results for the density fluctuations and the entanglement entropy of a one-dimensional trapped Bose gas in the Tonks–Girardeau (TG) or hard-core limit, after a trap quench from a double well to a single well. On the analytical side, the quadratic nature of the theory of QGHD is complemented with the emerging conformal invariance at the TG point to fix the universal part of those quantities. Moreover, the well-known mapping of hard-core bosons to free fermions, allows to use a generalized form of the Fisher–Hartwig conjecture to fix the non-trivial spacetime dependence of the ultraviolet cutoff in the entanglement entropy. The free nature of the TG gas also allows for more accurate results on the numerical side, where a higher number of particles as compared to the interacting case can be simulated. The agreement between analytical and numerical predictions is extremely good. For the density fluctuations, however, one has to average out large Friedel oscillations present in the numerics to recover such agreement
