El paper d’Alfred Morel-Fatio en els inicis de la catalanística
2022
El nostre objectiu en aquest article és fer una síntesi dels principals estudis d’Alfred Morel-Fatio sobre llengua i literatura catalanes, així com definir el seu paper en la catalanística del segle XIX, especialment a França però també a la resta d’Europa. Cal saber que aquest erudit francès va tenir un paper cabdal en el desplegament dels estudis universitaris catalans fora del nostre àmbit lingüístic, a banda de fer aportacions significatives al desplegament de la filologia catalana. Així, arribem a la conclusió que Morel-Fatio té el mèrit de ser el primer professor que va introduir l’estudi de la llengua i la literatura catalanes a les aules universitàries. A banda d’això, no es pot obv…
A non-cooperative approach to the folk rule in minimum cost spanning tree problems
2023
This paper deals with the problem of finding a way to distribute the cost of a minimum cost spanning tree problem between the players. A rule that assigns a payoff to each player provides this distribution. An optimistic point of view is considered to devise a cooperative game. Following this optimistic approach, a sequential game provides this construction to define the action sets of the players. The main result states the existence of a unique cost allocation in subgame perfect equilibria. This cost allocation matches the one suggested by the folk rule.

European Career Development – A Challenge for European Human Resource Management
2013
Abstract European career development should be a challenge for each of us. Current situations, the European economic context, technological evolution, the opening of European labor market are allowing people to a higher mobility concerning personal career. Thus, the development of a European career can be a challenge for each of us, depending on personal choices and on the context and development of each person's life. Is European career a better solution for individual development? Is that professional perfection for each person? These are questions that I will try to answer in this study.
Piezoelectric bimorph response with imperfect bonding conditions
2008
The effect of the finite stiffness bonding between the piezoelectric plies of bimorph devices has been investigated. A boundary integral formulation for piezoelasticity, based on a multidomain technique with imperfect interface conditions, has been developed. The imperfect interface conditions between the piezoelectric layers are described in terms of linear relations between the interface tractions, in normal and tangential directions, and the respective discontinuity in displacements. Continuity of the electric potential at the interface is also assumed and an iterative procedure is implemented to avoid interface interference. Numerical analysis has been performed on bimorph configuration…
Moving RTS/CTS to the frequency domain: an efficient contention scheme for 802.11ax networks
2019
In this paper, we propose a contention mechanism based on the execution of multiple contention rounds in the frequency domain (ReCHo), which is designed to offer high throughput performance and robustness with respect to imperfect carrier sensing. The main idea is using narrow tones as signalling messages for performing channel access contentions and allowing the Access Point (AP) to echo these signals, in order to extend the sensing capabilities to all the stations associated to the AP. In particular, we refer to the emerging IEEE 802.11ax standard, showing how our scheme can boost performance of random access with respect to the current version of IEEE 802.11ax OFDMA Back-Off (OBO), even …
'Good to Repeat': Making Random Access Near-Optimal with Repeated Contentions
2020
Recent advances on WLAN technology have been focused mostly on boosting network capacity by means of a more efficient and flexible physical layer. A new concept is required at MAC level to exploit fully the new capabilities of the PHY layer. In this article, we propose a contention mechanism based on Repeated Contentions (ReCo) in frequency domain. It provides a simple-to-configure, robust and short-term fair algorithm for the random contention component of the MAC protocol. The throughput efficiency of ReCo is not sensitive to the number of contending stations, so that ReCo does not require adaptive tuning of the access parameters for performance optimization. Efficiency and robustness is …
Imperfections et hybridation générique dans « Les Employés » d’Honoré de Balzac
2020
L’imperfezione dell’essere umano e delle sue costruzioni sociali è al centro della Comédie humaine. Il presente articolo intende esplorare questo aspetto della produzione letteraria di Balzac attraverso l’analisi de Les Employés (1845), in cui la mediocrità del mondo burocratico viene esaminata in dettaglio. Nel romanzo, la mediocrità vince sul merito, ma la rappresentazione dell’imperfezione trascende la dimensione puramente narrativa: Les Employés è un grande laboratorio in cui l’ibridazione tra genere romanzesco e genere teatrale interroga i limiti della creazione letteraria. The imperfection of the human being and his social constructions is at the heart of the Comédie humaine. This art…
Delegated agency in multiproduct oligopolies with indivisible goods
2010
This paper focuses on oligopolistic markets in which indivisible goods are sold by multiproduct firms to a continuum of homogeneous buyers, with measure normalized to one, who have preferences over bundles of products. Our analysis contributes to the literature on delegated agency games with direct externalities and complete information, extending the insights by Berheim and Whinston (1986, a , b) to markets with indivisibilities. By analyzing a kind of extended contract schedules - mixed bundling prices - that discriminate on exclusivity, the paper shows that efficient equilibria always exist in such settings. There may also exist inefficient equilibria in which the agent chooses a subopti…
On Capturing Oil Rents with a National Excise Tax Revisited
2004
In this paper the scope of Bergstrom’s (1982) results is studied. Moreover, his analysis is extended assuming that extraction cost is directly related to accumulated extractions. For the case of a competitive market it is found that the optimal policy is a constant tariff if extraction is costless. However, with depletion effects, the optimal tariff must ultimately be decreasing. For the case of a monopolistic market the results depend crucially on the kind of strategies the importing country governments can play and on whether the monopolist chooses the price or extraction rate. For a price-setting monopolist it is shown that the importing countries cannot use a tariff to capture monopoly …
