An extension and an alternative characterization of May’s theorem
Freixas Bosch, Josep; Pons Vallès, Montserrat (Springer, 2021-03-14)
Article
Accés obertThe context of this work is a voting scenario in which each voter expresses his/her level of affinity about a proposal, by choosing a value in the set J={-j,…,-1,0,1,…,j}, and these individual votes produce a collective ... -
Anonymous yes-no voting with abstention and multiple levels of approval
Freixas Bosch, Josep; Zwicker, William S. (Academic Press, 2009-11)
Article
Accés obertEls jocs simples simètrics (3, 2) serveixen de models per a sistemes de votació anònims en els quals cada votant pot votar "sí", abstenir-se, o votar "no", el resultat és "sí" o "no", i els votants juguen papers intercanviables. ... -
Bounds for the Nakamura number
Freixas Bosch, Josep; Kurz, Sascha (Springer, 2019-04)
Article
Accés obertThe Nakamura number is an appropriate invariant of a simple game to study the existence of social equilibria and the possibility of cycles. For symmetric (quota) games its number can be obtained by an easy formula. For ... -
Complete voting systems with two types of voters: weightedness and counting
Freixas Bosch, Josep; Molinero Albareda, Xavier; Roura Ferret, Salvador (2012)
Article
Accés restringit per decisió de l'autorWe investigate voting systems with two classes of voters, for which there is a hierarchy giving each member of the stronger class more influence or important than each member of the weaker class. We deduce for voting systems ... -
Components with higher and lower risk in a reliability system
Freixas Bosch, Josep; Pons Vallès, Montserrat (Fundación Mapfre, 2015)
Text en actes de congrés
Accés obertA new reliability importance measure for components in a system, that we call Representativeness measure, is introduced. It evaluates to which extent the performance of a component is representative of the erformance of ... -
Computation of several power indices by generating functions
Alonso Meijide, José María; Freixas Bosch, Josep; Molinero Albareda, Xavier (2012)
Article
Accés obertIn this paper we propose methods to compute the Deegan-Packel, the Public Good, and the Shift power indices by generating functions for the particular case of weighted voting games. Furthermore, we define a new power ... -
Consecutive expansions of k-out-of-n structures
Freixas Bosch, Josep; Puente del Campo, María Albina (2009)
Report de recerca
Accés restringit per decisió de l'autorEstudi dels sistemes obtinguts per expansions succesives -
Consecutive expansions of k-out-of-n systems
Freixas Bosch, Josep; Puente del Campo, María Albina (2009-11)
Article
Accés obertS'introdueixen expansions de sistemes k-out-of-n. Es proposen algunes fórmules per fer més fàcil de comptabilitzar aquestes mesures i estudiar-ne les jerarquies. -
Decisiveness indices are semiindices
Freixas Bosch, Josep; Pons Vallès, Montserrat (2016-06)
Article
Accés obertIn this note we prove that any decisiveness index, defined for any voter as the probability of him/her being decisive, is a semiindex when the probability distribution over coalitions is anonymous, and it is a semiindex ... -
Decisiveness indices are semiindices: addendum
Freixas Bosch, Josep; Pons Vallès, Montserrat (2017-01-01)
Article
Accés obertIn the paper Decisiveness indices are semiindices (Freixas and Pons, 2016) it was shown that any decisiveness index obtained from an anonymous probability distribution is a semiindex, and that the converse is not true. In ... -
Decisiveness of decisive symmetric games
Carreras Escobar, Francisco; Freixas Bosch, Josep; Puente del Campo, María Albina (2011-04-08)
Report de recerca
Accés obertBinary voting systems, usually represented by simple games, constitute a main DSS topic. A crucial feature of such a system is the easiness with which a proposal can be collectively accepted, which is measured by the ... -
Dimension, egalitarianism and decisiveness of European voting systems
Carreras Escobar, Francisco; Freixas Bosch, Josep; Magaña Nieto, Antonio (2016)
Article
Accés obertAn analysis of three major aspects has been carried out that may apply to any of the successive voting systems used for the European Union Council of Ministers, from the first one established in the Treaty of Rome in 1958 ... -
Effect of a science communication event on students’ attitudes towards science and technology
Torras Melenchón, Núria; Grau Vilalta, Maria Dolors; Font Soldevila, Josep; Freixas Bosch, Josep (Tempus Publications, 2017)
Article
Accés obert -
Egalitarian property for power indices
Freixas Bosch, Josep; Marciniak, Dorota (Springer, 2013)
Article
Accés obertIn this study, we introduce and examine the Egalitarian property for some power indices on the class of simple games. This property means that after intersecting a game with a symmetric or anonymous game the difference ... -
Enumeration of weighted games with minimum and an analysis of voting power for bipartite complete games with minimum
Freixas Bosch, Josep; Kurz, Sascha (2014-11)
Article
Accés obertThis paper is a twofold contribution. First, it contributes to the problem of enumerating some classes of simple games and in particular provides the number of weighted games with minimum and the number of weighted games ... -
Estrategias óptimas de un juego bipersonal de suma cero y puntos de ensilladura del campo escalar asociado
Freixas Bosch, Josep (Institut d'Estadística de Catalunya, 1993)
Article
Accés obertDefinimos el campo escalar asociado a un juego bipersonal de suma cero. Estudiamos la existencia y unicidad de puntos estacionarios y obtenemos la forma general de los mismos en caso de unicidad. Se establece que todo punto ... -
