Limited preparation contextuality in quantum theory and its relation to the Cirel'son bound
2015
Kochen-Specker (KS) theorem lies at the heart of the foundations of quantum mechanics. It establishes impossibility of explaining predictions of quantum theory by any noncontextual ontological model. Spekkens generalized the notion of KS contextuality in [Phys. Rev. A 71, 052108 (2005)] for arbitrary experimental procedures (preparation, measurement, and transformation procedure). Interestingly, later on it was shown that preparation contextuality powers parity-oblivious multiplexing [Phys. Rev. Lett. 102, 010401 (2009)], a two party information theoretic game. Thus, using resources of a given operational theory, the maximum success probability achievable in such a game suffices as a \emph{…
Se l’enunciatore non parla. Note sulla nozione ducrotiana di punto di vista.
2018
«Voice» and «Point of view» have been two of the most debated topics in some fields of linguistics and semiotics. Generally, DUCROT (1984) is considered like one of the first essays which introduced these concepts in the theoretical framework of the analysis of enunciation. As for the first one, the Author limits himself to suggest that it is connected with the notion of «discourse». In fact, by examining some topics of SPERBER & WILSON (1978), he seems to assimilate «voice» to «discourse». Indeed, you can read «j’ai substitué l’expression “faire entendre une voix” à leur expression “mentionner un discours”». As for the second concept, He seems to assimilate «point of view» to intuitive not…
Multi-Alkenylsilsesquioxanes as Comonomers and Active Species Modifiers of Metallocene Catalyst in Copolymerization with Ethylene.
2018
The copolymers of ethylene (E) with open-caged iso-butyl-substituted tri-alkenyl-silsesquioxanes (POSS-6-3 and POSS-10-3) and phenyl-substituted tetra-alkenyl-silsesquioxane (POSS-10-4) were synthesized by copolymerization over the ansa-metallocene catalyst. The influence of the kind of silsesquioxane and of the copolymerization conditions on the reaction performance and on the properties of the copolymers was studied. In the case of copolymerization of E/POSS-6-3, the positive comonomer effect was observed, which was associated with the influence of POSS-6-3 on transformation of the bimetallic ion pair to the active catalytic species. Functionality of silsesquioxanes and polymerization par…
Populismin väkevöityminen
2020
Artikkelissa tarkastellaan populismin ideologista väkevöitymistä populistisen radikaalioikeiston herättämänä kysymyksenä. Ernesto Laclaun käsittein kuvataan aluksi argumentaatioltaan heikoksi mainitun populistisen retoriikan liikettä muodostavaa voimaa. Laclaun kuvaamat ”tyhjät” ja ”kelluvat” merkitsijät voivat panostua myös ideologisesti liikkeen luonnetta muuttavalla tavalla. Populismin ytimeltään heikko ideologisuus altistaa uusiin ideologisiin linkityksiin ja panosten väkevöitymiseen sen omassa retoriikassa. Siten ideologiaa ei ymmärretä vain populismia jälkikäteen vahvistavaksi aatteeksi, vaan sen merkitsijöitä muuttavaksi dynaamiseksi mahdollisuudeksi. ”Tyhjän merkitsijän” käsitteen k…
La definizione della possessio nel Festo Farnesiano fra tradizione manoscritta, edizioni e interpretazione storiografica
2016
La comprensione della definizione di possesso fornita da Elio Gallo (ap. Fest., p. 260-262 L.) dipende dalla ricostruzione del testo tramandato nel Codice Farnesiano (Napoli, Biblioteca Nazionale, Neap. IV A 3). Una nuova analisi della tradizione manoscritta compiuta in una più ampia prospettiva consente di verificare se e in quale misura la circolarità ermeneutica ha condizionato le edizioni a stampa su cui sono basate le varie interpretazioni di tale definizione. The understanding of the definition of possession by Aelius Gallus (ap. Fest., p. 260-262 L.) depends on the reconstruction of the text preserved in the Codex Farnesianus (Napoli, Biblioteca Nazionale, Neap. IV A 3). A new analys…

Espace et conflit : le choix des investissements dans des régions à risques
1988
Dans le classement et le choix des investissements, les risques dans l'espace doivent être ajoutés à l'incertitude du futur dans le cadre d'un calcul économique élargi. Cette approche permet de définir des critères pour évaluer les méthodes pratiques d'estimation des risques régionaux.
Modeling recurrent distributions in streams using possible worlds
2015
Discovering changes in the data distribution of streams and discovering recurrent data distributions are challenging problems in data mining and machine learning. Both have received a lot of attention in the context of classification. With the ever increasing growth of data, however, there is a high demand of compact and universal representations of data streams that enable the user to analyze current as well as historic data without having access to the raw data. To make a first step towards this direction, we propose a condensed representation that captures the various — possibly recurrent — data distributions of the stream by extending the notion of possible worlds. The representation en…
Leibniz, Modal Logic and Possible World Semantics: The Apulean Square as a Procrustean Bed for His Modal Metaphysics
2012
Even if Leibniz didn’t have the opportunity to actually conceive an explicit modal logic system, remains the fact that he had worked out a modal metaphysics, of which the inaugural act, in his Elementa juris naturalis (c. 1671) was an obvious reference to the Apulean square of opposition. Later, scholars acknowledged in this passage probably one of the first sketch of deontic logic of norms. His modal metaphysics rather deals with the so-called alethic modalities, sometimes expounded through a language such as R.M. Adams wondered whether Leibniz could be “a sort of grandfather of possible worlds semantics for modal logic”. In the following study, the Apulean square is used as a hermeneutic …
