Linear NIMROD simulations of n = 0 modes for straight tokamak configuration and comparison with analytic results
No full textComparison between the analytic theory of n = 0 vertical displacement modes in magnetically confined plasmas of fusion interest and numerical simulations using the extended-MHD code NIMROD is presented. Agreement between analytic and numerical results is highly satisfactory. Differences are interpreted to be caused mostly by the different wall shape and by the presence of a halo plasma surrounding the hot plasma adopted in NIMROD. A numerical study of vertical displacement oscillatory modes [Barberis et al., J. Plasma Phys. 88, 905880511 (2022)] is presented. Axisymmetric X-point currents supported by the halo plasma are discussed. The article provides a successful benchmark and a useful starting point for future numerical investigations of n = 0 modes using more realistic tokamak geometry and plasma equilibria
“Cultura manageriale e identità lavorativa nei sistemi di istruzione. Un’introduzione
No full textThe article deals with the Managerial culture and work identity in education systems”. The first section contextualizes the adoption of neoliberal measures in the working logic of public administration. Foundations of New Public Management and their relevance for education systems are set – together with the idea that they are as relevant as not the only cause of transformation in educational professions and organizations. The second section focuses on the effects of managerial elements on professional practices, where neoliberal recipes are nested in prior organizational models. The third section pays attention to implications for educational professionals, in particular in respect to job fragmentation and individual responsibilization

No full textFerrajoli, or neo-constitutionalism not taken seriously
No full textEsta última contribucción de Ferrajoli al debate sobre el (neo)constitucionalismo requiere cinco críticas: primero, el enfoque deductivista coherentemente adoptado por el autor desde Teoría assiomatizzata del diritto hasta Principia iuris deja muy poco espacio para la interpretación y la argumentación en el razonamiento jurídico; segundo, el propio problema de la relación entre derecho y moral no está verdaderamente discutido por él; tercero, cuarto y quinto, el mismo enfoque deductivista fuerza a Ferrajoli a reducir los principios a reglas, a ignorar el papel democrático que podría cumplir una ponderación actuada por el legislador y no por el juez, y a resolver de una discutible manera monista el problema pluralista del conflicto entre derechos.This Ferrajoli’s last contribution to debate on (neo)constitutionalism deserves five criticism: first, deductivist approach coherently adopted by the author from Teoria assiomatizzata del diritto to Principia iuris leaves too little a stance for interpretation and argumentation in legal reasoning; second, the very problem of law-morals relations is not discussed but eluded by him, fourth and fifth, the same deductivist approach must constrain Ferrajoli to reduce principles to rules, to ignore the democratic role that could be carried out by a legislative and no-judicial balancing, and to provide a dubious monist answer to the pluralist question of conflict among rights
Brexit, Trump e governo giallo-verde. Tre esempi di populismo digitale
No full textWe talk about populism, in particular in the digital sense that I believe the scholars should privilege, starting from three events: Brexit, Trump administration, Yellow-green government in Italy. This paper shows how in all three cases the internet was decisive. In the Brexit case, a typical example of digital populist opposition, the profiling and micro-targeting techniques were decisive for Leave to win the referendum. In the Trump case, a typical example of populist government, the occupation of the media through the use of Twitter was even more decisive than Russiagate and Cambridge Analytica. Finally, in
the case of the Italian Yellow-green government, Facebook’s callous use was decisive for the rise of the Salvini’s League and the fall of Five Stars Movement.
In the face of all this, the Author believes that Western elites have three obligatory paths: at the very least, to use the Internet better than their opponents; as a maximum, to tackle the major socio-economic problems that fuel populist resentment; as an intermediate yet most urgent solution, the Internet must be regulated
Diritto e morale: la discussione odierna
No full textFour philosophies of law are compared and discussed in this paper: natural law, legal positivism, legal realism, ans neo-constitutionalism. Each of them is defined upon its answers to three questions: one regards objectivity or subjectivity of ethical (i.e. moral, political, legal) value judgements, another one refers to legal interpretation, and the main one to the relationships between law and morality. Natural Law is thus characterised by (i) ethical objectivism, (ii) interpretive formalism, and (iii) the idea that law and morality are necessarily connected. Positivism stands for (i) ethical subjectivism, (iii) mixed theory of legal interpretation, and (iii) the separability thesis. Legal realism – which is, to some extent, a mere radicalisation of positivistic views – is chacterised by (i) ethical subjectivism, (ii) interpretive scepticism, and (iii) the separation thesis. Neo-constitutionalism holds (i) ethical objectivism, (ii) interpretive formalism, and (iii) the view that law and morality are anyhow connected in a constitutional state (thus making the debate between natural law and positivism outdated). Each of the four philosophies of law is then articulated into its respective theoretical, methodological and ideological aspects. This is how the author points to certain similarities between the opposite standpoints, and to some plurality of views inside of every one of them. He stresses furthermore the challenges for particular views on law and morality with the final analysis of three interpretations of the separability thesis – given by inclusive, exclusive and normative positivists. The paper is published here in Italian original and in Slovenian translation
