Decisiveness indices are semiindices: addendum

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 this note we characterize the semiindices which are indices of decisiveness.Peer ReviewedPostprint (author's final draft

Dwarfs, giants, princesses and dragons in classical Antiquity: some connections between folktale, children’s literature and classical myth

La intención principal del presente artículo no es dar unas directrices precisas a los docentes de primaria, sino presentarles un material alternativo a los cuentos tradicionales y la literatura infantil basado en las raíces culturales de nuestra civilización y su rico patrimonio a fin de que estos lo adapten de la manera que crean más adecuada a las necesidades de sus alumnos.The main intention of this article is not giving precise instructions to the teachers in primary education, but to present an alternative material to folktales and children’s literature based on the cultural roots of our civilization and its rich heritage so that they fit the way it seems most appropriate to the needs of their pupils.peerReviewe

Joint beamforming and channel estimation for pilot-aided WCDMA systems

The problem of joint beamforming and channel estimation for multi-rate multi-code systems is addressed. Usual schemes perform this filtering/estimation operation making use of a training sequence time-multiplexed with the transmitted data. However if pilot and traffic signals are transmitted simultaneously using distinct code allocation-as it is the case in recent standards such as cdma2000 or WCDMA-these schemes tend to fail. This paper proposes semi-blind techniques to overcome the uplink auto-interfering effects of such systems. It is shown that the semi-blind approach yields substantially better performance results thanks to the implicit modeling of the unknown traffic data.Peer ReviewedPostprint (published version

The Autonomous Capacity of the Elderly Population in Spain for Shopping and Preparing Meals

A loss of the ability to buy and prepare meals, especially in people aged 65 and over, leads to a deterioration in their optimal level of nutrition. The Index of Autonomy in Food Acquisition (IAFA) was used to identify contributing factors. This is a composite indicator for shopping and meal preparation that can be used to assess the degree of autonomous capacity observed in a spe-cific group. Data from the European Health Survey in Spain (7167 respondents aged 65 and over) show that capacity decreased with age and that women were less affected than men, with very little difference found in levels of autonomous capacity by territory. However, in relation to dif-ferent income levels, after standardizing for age and sex, no evidence was found for differences in the ability to access and prepare meals in groups that were separated by income level. This result shows the importance of standardizing when analysing food acquisition autonomy in groups of people aged 65 years and over

Using the multilinear extension to study some probabilistic power indices

The final publication is available at Springer via http://dx.doi.org/10.1007/s10726-016-9514-6We consider binary voting systems modeled by a simple game, in which voters vote independently of each other, and the probability distribution over coalitions is known. The Owen’s multilinear extension of the simple game is used to improve the use and the computation of three indices defined in this model: the decisiveness index, which is an extension of the Banzhaf index, the success index, which is an extension of the Rae index, and the luckiness index. This approach leads us to prove new properties and inter-relations between these indices. In particular it is proved that the ordinal equivalence between success and decisiveness indices is achieved in any game if and only if the probability distribution is anonymous. In the anonymous case, the egalitarianism of the three indices is compared, and it is also proved that, for these distributions, decisiveness and success indices respect the strength of the seats, whereas luckiness reverses this order.Peer ReviewedPostprint (author's final draft

Decisiveness indices are semiindices

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 with binomial coefficients when the probability over coalitions is anonymous and independent.Peer ReviewedPostprint (author's final draft

An extension and an alternative characterization of May’s theorem

This is a post-peer-review, pre-copyedit version of an article published in Annals of Operations Research. The final authenticated version is available online at: http://dx.doi.org/10.1007/s10479-021-04044-w.The 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 result, in the same set J, through a decision function. The simple majority, defined for j=1, is a widely used example of such a decision function. In this paper, a set of independent axioms is proved to uniquely characterize the j-majority decision function. The j-majority decision is defined for any positive integer j, and it coincides with the simple majority decision when j=1. In this way, this axiomatic characterization meets two goals: it gives a new characterization of the simple majority decision when j=1 and it extends May’s theorem to this broader context.This research has been partially supported by funds from the Ministry of Science and Innovation grant PID2019-104987GB-I00.Peer ReviewedPostprint (author's final draft
