Problemi di giurisdizione nel contrasto al traffico di migranti via mare
2018
I trafficanti di esseri umani si avvalgono con sempre più insistenza di ben collaudati protocolli operativi. Questi ultimi consentono loro di sottrarsi alla giurisdizione penale italiana che non si radica qualora – in ossequio ai criteri di cui all’art. 6 c.p.ed in conformità alla Convenzione sull’Alto Mare– l’azione illecita avvenga in acque internazionali.Così, premesse alcune linee concettuali sui limiti spaziali alla efficacia della legge penale, l’indagine si sofferma sulla soluzione ermeneutica offerta dallaCassazione che, apparentemente in modo sbrigativo e per esigenze di effettività della risposta punitiva, ha fatto ricorso alla controversa figura dell’autore mediato per sanzionare condott…
In the Shadows of a hypergraph: looking for associated primes of powers of squarefree monomial ideals
2018
The aim of this paper is to study the associated primes of powers of square-free monomial ideals. Each square-free monomial ideal corresponds uniquely to a finite simple hypergraph via the cover ideal construction, and vice versa. Let H be a finite simple hypergraph and J(H) the cover ideal of H. We define the shadows of hypergraph, H, described as a collection of smaller hypergraphs related to H under some conditions. We then investigate how the shadows of H preserve information about the associated primes of the powers of J(H). Finally, we apply our findings on shadows to study the persistence property of square-free monomial ideals and construct some examples exhibiting failure of contai…

Il perimetro variabile dell’insindacabilità dei Consiglieri regionali: la vis politica delle decisioni “strategiche” per l’economia regionale. Nota a…
2022
La sentenza n. 90 del 2022 della Corte costituzionale risolve un conflitto di attribuzioni fra Stato e Regione Valle d’Aosta originato dalla sentenza della sezione giurisdizionale III centrale della Corte dei conti (la nr. 350 del 2021) di condanna per responsabilità da danno erariale nei confronti di diversi Consiglieri della Regione per aver deliberato un atto amministrativo concernente un’operazione di rifinanziamento del Casinò di Saint-Vincent. A differenza dei criteri precedentemente seguiti per definire l’ambito di applicazione dell’insindacabilità dei Consiglieri regionali nell’ipotesi di deliberazioni consiliari relative ad atti non legislativi (cfr. spec. Corte cost. nn. 69 e 70 d…
Institutions and Deontic Powers: Some Comments on the Tuomela-Searle Debate
In this talk I will analyze Tuomela’s theory of institutions and the most recent debate with Searle over the issue of whether institutions conceptually involve the creation and distribution of deontic powers. By way of analyzing Tuomela and Searle’s reciprocal criticisms, I conclude that Tuomela does not give us sufficient reasons to give up Searle’s thesis that institutions always involve deontic powers, but I also argue that it is necessary to go beyond Searle’s recent speech act-centered explanation of human sociality. More specifically, moving along the lines of Di Lorenzo’s view of constitutive rules as built into the logical and pragmatic structure of human activities, and making use …
Elogio delle virtù nell’immagine politica di Giuliano in Libanio
2014
Libanius’ Julianic orations play an important role to move closer to knowledge of the interior portrait of this emperor. Julian’s personality is based on four virtues: philoponia, phronesis, philanthropia, sophrosyne. These virtues are panegyrical topoi in the eulogy of the rulers (Basilikos logos), and in the Libanian context they are freely reused, adapted to the present in order to return an image of Julian politically useful; all this doesn’t necessarily imply systematic distortion of the truth. In this connection, Julian’s political image is the exact opposite of the image of his predecessor: the reader is given the conviction that Constance, unlike Julian, would have achieved only a s…
Steiner systems and configurations of points
2020
AbstractThe aim of this paper is to make a connection between design theory and algebraic geometry/commutative algebra. In particular, given any Steiner SystemS(t, n, v) we associate two ideals, in a suitable polynomial ring, defining a Steiner configuration of points and its Complement. We focus on the latter, studying its homological invariants, such as Hilbert Function and Betti numbers. We also study symbolic and regular powers associated to the ideal defining a Complement of a Steiner configuration of points, finding its Waldschmidt constant, regularity, bounds on its resurgence and asymptotic resurgence. We also compute the parameters of linear codes associated to any Steiner configur…
A Compact Representation of Preferences in Multiple Criteria Optimization Problems
2019
A critical step in multiple criteria optimization is setting the preferences for all the criteria under consideration. Several methodologies have been proposed to compute the relative priority of criteria when preference relations can be expressed either by ordinal or by cardinal information. The analytic hierarchy process introduces relative priority levels and cardinal preferences. Lexicographical orders combine both ordinal and cardinal preferences and present the additional difficulty of establishing strict priority levels. To enhance the process of setting preferences, we propose a compact representation that subsumes the most common preference schemes in a single algebraic object. We …
Infección controlada. Maneras de representar el estado de excepción en el cine de pandemias
2018
En el presente escrito se muestra cómo el cine de las décadas posmodernistas ha plasmado un estado político singular, el de excepción, vinculado en estas películas a la propagación de una pandemia. Como arte popular, el cine ha sido una herramienta potentísima para crear imaginarios en la sociedad del capitalismo avanzado y para influir en lo que los ciudadanos estimen probable de una situación dada. El motivo de la declaración de emergencia, control militar y estado de excepción se ha convertido durante esas décadas en uno de los más utilizados, especialmente en los blockbusters de género fantástico. In this paper it’s argued how the movies from the postmodernist decades have shown a singu…
Los principales retrocesos promovidos por la Ley Forestal brasileña de 2012
2019
El objetivo de este estudio es analizar los principales retrocesos introdu-cidos por la Ley Forestal de Brasil de 2012 y el contexto político de su formulación. El aná-lisis se basa en la comparación de las reglas que disciplinan los Institutos del Área de Pre-servación Permanente (APP) y del Área de Reserva Legal (ARL) en propiedades agrarias privadas por las Leyes Forestales de 1965 y 2012. Así como en las posiciones y los intere-ses de los actores más relevantes en relación con la protección de los bosques naturales, poniendo de relieve la gran influencia del sector agrario. El estudio demuestra que la Ley Forestal de 2012 fue formulada para anular casi completamente los dos principales …
