Dynamics of predator-prey models with a strong Allee effect on the prey and predator-dependent trophic functions
No full textThe complex dynamics of a two-trophic chain are investigated. The chain is described by a general predator-prey system, in which the prey growth rate and the trophic interaction functions are defined only by some properties determining their shapes. To account for undercrowding phenomena, the prey growth function is assumed to model a strong Allee effect; to simulate the predator interference during the predation process, the trophic function is assumed predator-dependent. A stability analysis of the system is performed, using the predation efficiency and a measure of the predator interference as bifurcation parameters. The admissible scenarios are much richer than in the case of prey-dependent trophic functions, investigated in Buffoni et al. (2011). General conditions for the number of equilibria, for the existence and stability of extinction and coexistence equilibrium states are determined, and the bifurcations exhibited by the system are investigated. Numerical results illustrate the qualitative behaviours of the system, in particular the presence of limit cycles, of global bifurcations and of bistability situations
La rappresentazione del Parlamento
No full textThe paper aims to show the relationship beetwen parlamentary publicity, democratic principle and representative principle. Then, the author tries to investigate if the new forms of publicity of parlamentary acts are an able answer to the crisis of representa- tion in constitutional democracy
La rappresentanza politica. Note sul rapporto di prossimità ‘divergente’ tra processo e valore (di legge)
No full textThe paper aims to give an account of the issues of representation in public law, treated in connection with the procedural theories. The author tries to rethink, between political and legal constitutionalism, the representation, which also today shapes the de- liberativist democratism and the Rousseau’s constitutionalism. It looks at the represen- tation as a force of quality 'active' than the social pluralism, which gives form to the ideas (people, nation .. ) that did not pre-exist
La fisica come modello per il dritto?
No full textSOMMARIO: 1. L’epistemologia “fisicalista” di Bin. - 2. Sulla corrispondenza tra teoria kelseniana delle
fonti del diritto e approccio newtoniano. - 2.1 La pratica della gerarchia normativa come limite dei
giudici al potere politico. - 3. Dalla meccanica quantistica alla teoria delle stringhe. - 3.1
Dell’ontologia degli oggetti sociali. - 4. I continentali ed il postpositivismo giuridico analitico: il diritto
come modello per le scienze naturali. - 5. La teoria discorsiva dell’interpretazione giuridica,
l’uditorio ed il mondo delle probabilità.The article aims to discuss the theory presented by professor Roberto
Bin in the book “A discrezione del giudice. Ordine e disordine. Una prospettiva
quantistica” (Milano, Franco Angeli, 2013), according to which physical metaphors
and intuitions can improve our comprehension of legal issues. In his book Professor
Bin uses some paradigmatic shifts in physics (such as relativity theory and quantum
physics) to illustrate the need of a revised constitutional theory. He argues, as Professor
Lawrence Tribe firstly did in a famous essay of 1989, that scholars and lawyers
can learn form modern physics, and, in particular, from quantum physics, to
undermine the confidence of scientists in their ability to observe a phenomenon without
altering it.
Although agreeing with the heuristic ramification of the philosophy of science for
legal studies and considering these metaphors as stimulating new studies, the Author
argues that it is not correct to refer to natural sciences, such as physics, to leave the
objective image of legal universe and particularly of constitutional issues. This is
true, mainly because there is not an epistemological hierarchy between natural and
social sciences. Even the scientific decisions borrow methodological options from
the post-positivism science law – especially from the discursive theory of legal justification.
In this perspective, at the opposite, natural sciences have to refer to legal
doctrine
La filosofia della scienza e lo studio delle fonti del diritto: appunti per una critica del “fisicalismo” giuridico
No full textIn questo saggio viene discussa la proposta teorica formulata da Roberto Bin
nel libro, A discrezione del giudice. Ordine e disordine: una prospettiva
quantistica, secondo cui la fisica ed i suoi presupposti epistemologici possono
aiutare, secondo una intuizione di L. Tribe del 1989, a fondare, su nuove basi,
la teoria delle fonti del diritto e dell’interpretazione giuridica. In particolare,
l’applicazione delle premesse epistemologiche della fisica quantistica alla
teoria del diritto svelerebbe il determinismo newtoniano della teoria kelseniana
delle fonti (e dell’interpretazione) del diritto e la sovrapposizione tra il soggetto
che interpreta e l’oggetto interpretato. L’Autore di questo lavoro, benché ritenga stimolante la metafora “fisicalista”, sostiene che non è necessario
postulare premesse fisiche per spiegare il fenomeno giuridico. E questo perché
non vi è alcuna gerarchia epistemologica tra le scienze naturali e le scienze
sociali che prescriva di mutuare il metodo interpretativo dalla fisica. Al
contrario, gli stessi fatti possono essere già spiegati con il discorso interno al
diritto, quello proprio della teoria discorsiva dell’interpretazione giuridica e,
soprattutto, gli stessi fisici costruiscono discorsivamente le proprie teorie,
secondo l’opzione teorica propugnata dal post-positivismo giuridico analitico.The article aims to discuss the theory presented by Roberto Bin in his book A
discrezione del giudice. Ordine e disordine: una prospettiva quantistica,

Appunti per una semantica della rappresentanza politica: note ‘libere’ dall’incontro sassarese su “La rappresentanza nel diritto pubblico”
No full textIl lavoro si propone di dar conto delle questioni su “La rappresentanza nel diritto pubblico” messe in gioco nell’incontro sassarese del 6 novembre 2014, immaginando di proseguire il dialogo con i relatori. Alle riflessioni del costituzionalista Caretti, che ha esperito il tentativo di delineare l’evoluzione (che si è rivelata involuzione) del concetto di rappresentanza politica dalle soglie della modernità sino allo Stato costituzionale contemporaneo, segue la critica radicale della logica della rappresentanza del romanista Lobrano, che oppone al modello del costituzionalismo medievale-inglese o parlamentare-rappresentativo il modello romano-repubblicano-municipale, del quale propone il recupero del contratto di societas contro l’inganno della persona ficta vel repraesentata. Il filosofo politico Mura, infine, ha guardato alla rappresentanza politica come forma moderna di legittimazione politica dell’autorità ed ha isolato due concezioni della rappresentanza nella storia del pensiero politico occidentale: la sostituzione di persone vs la sostituzione di volontà.
L’autrice prova a ripensare la rappresentanza, della quale neppure il democraticismo deliberativista o il costituzionalismo rousseauviano paiono sino in fondo liberarsi, come una forza di qualità ‘attiva’ rispetto al pluralismo sociale, che mette in forma le idee (popolo, nazione..) che non le preesistono.The paper aims to give an account of the issues of "representation in public law" treated in the Sassari’s meeting of 6 November 2014, imagining to continue the dialogue with the speakers. First, the constitutionalist Caretti has performed an attempt to outline the evolution (which proved involution) of the concept of political representation from the threshold of modernity up to the State Constitutional contemporary. Second, the Romanist Lobrano had a radical criticism of the logic of representation, that opposed the model of constitutionalism-medieval English or parliamentary-representative to the Roman-republican model, which proposes the recovery of the contract societas against the deception of the person ficta vel repraesentata. Finally, the political philosopher Mura looked to political representation as a modern form of political legitimacy of the authority and underlined the existence two conceptions of representation in the history of Western political thought: the replacement of people against the replacement of will.
The author tries to rethink the representation, which also today shapes the deliberativist democratism and the Rousseau’s constitutionalism, as a force of quality 'active' than the social pluralism, which gives form to the ideas (people, nation .. ) that did not pre-exist

The c-kit receptor and its ligand stem cell factor in childhood malignant lymphoid precursors
No full textThe c-kit receptor (CD117) and its ligand stem cell factor (SCF) play an important role in the development, differentiation, and survival of normal and malignant hematopoietic cells. The aim of this work is to review the cellular distribution of this receptor and the effect of SCF on the hematopoietic system, particularly among lymphoid lineage, either in normal or malignant cell progenitors. We examined reports and results in the field and articles or abstracts published in journals covered by MEDLINE. Additionally, we evaluated CD117 expression on fresh blast cells of 376 newly diagnosed cases of childhood acute lymphoblastic leukemia (ALL) that were referred to centers affiliated with the Italian Association for Pediatric Hematology and Oncology (AIEOP). In view of our data, approximately 11% of ALL are CD117 positive. In particular, this receptor can be expressed in 10% and 11.5% of T-lineage and B-lineage ALL, respectively. Its expression is associated with an intermediate/mature phenotype in T-lineage ALL, whereas in B-lineage ALL, the majority of the positive cases are classified as early B ALL. The effect of SCF on malignant hematopoiesis and its potential clinical uses are reviewed
