      S'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
      Open Access
      In 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
      Open Access
      In 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)
      External research report
      Open Access
      Binary 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 ...

      Carreras Escobar, Francisco; Freixas Bosch, Josep; Magaña Nieto, Antonio (2016)
      Article
      Open Access
      An 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

    • Egalitarian property for power indices 

      Freixas Bosch, Josep; Marciniak, Dorota (Springer, 2013)
      Article
      Open Access
      In 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
      Open Access
      This 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
      Open Access
      Definimos 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 ...
    • EXPLORE: an action to bring science and technology closer to secondary school

      This paper presents the experience of an initiative, the EXPLORE courses, designed to bring science and technology closer to secondary school and to encourage scientific and technological vocations. The EXPLORE courses, ...
    • Hierarchies achievable in simple games 

      Freixas Bosch, Josep; Pons Vallès, Montserrat (2010-04)
      Article
      Restricted access - publisher's policy
      A previous work by Friedman et al. (Theory and Decision, 61:305–318, 2006) introduces the concept of a hierarchy of a simple voting game and characterizes which hierarchies, induced by the desirability relation, are ...
    • Identifying optimal components in a reliability system 

      Freixas Bosch, Josep; Pons Vallès, Montserrat (Institute of Electrical and Electronics Engineers (IEEE), 2008-03)
      Article
      Open Access
      The first step in a reliability optimization process is to make a reliability assessment for each component in the system. If this assessment is made in a qualitative way, by grouping together components with the same ...
    • Manipulation in games with multiple levels of output 

      Freixas Bosch, Josep; Parker, Cameron (2015-12)
      Article
      Open Access
      In (j,k)-games each player chooses amongst j ordered options and there are k possible outcomes. In this paper, we consider the case where players are assumed to prefer some outcomes to others, and note that when k>2 the ...
