El Triumphus Mortis traducido por Juan Coloma

The aim of this article is to frame the translation of the Triumph of Death made by Juan Coloma within the lyric corpus of this poet. The relevant features of this translation are analysed in the context of other Castilian translations of the Triumphs in the 16th century; furthermore several hypotheses are suggested to explain why the Coloma’s translation was selected to be placed at the very beginning of the Cancionero general de obras nuevas (Zaragoza: Esteban Nájera, 1554).Este artículo pretende situar la traducción del Triunfo de la Muerte que realizó Juan Coloma dentro del corpus de la lírica profana de este poeta, mostrar las características más relevantes de esta composición en el contexto de las primeras traducciones al castellano de los Triunfos, y proponer varias hipótesis de trabajo que expliquen por qué fue elegido este poema para encabezar el Cancionero general de obras nuevas (Zaragoza: Esteban de Nájera, 1554)

Probabilistic memory-one strategies to dominate the iterated prisoner’s dilemma over networks

Financiado para publicación en acceso aberto: Universidade de Vigo/CISUGThe Iterated Prisoner’s Dilemma (IPD) has been a classical game theoretical scenario used to model behaviour interactions among agents. From the famous Axelrod’s tournament, and the successful results obtained by the Tit for Tat strategy, to the introduction of the zerodeterminant strategies in the last decade, the game theory community has been exploring the performance of multiple strategies for years. This article grounds on such previous work, studying probabilistic memory-one strategies (PMO) and using evolutionary game theory, to analyse the criteria to find the most successful set of strategies in networked topologies. The results are nearly deterministic in discrete PMO scenarios. However, results become much more complex when moving to continuous ones, and there is no optimal strategy for a given scenario. Finally, this article describes how, using machine learning and evolutionary techniques; a cluster of agents, playing synchronously and adaptively, is able to dominate the rest of the populatio

La contribución de las energías renovables al desarrollo rural sostenible en la Unión Europea: pautas teóricas para el análisis empírico

Ejemplar dedicado a: Marx, Keynes y SchumpeterEl marco en el que se desenvuelve actualmente el sector agrario europeo sitúa al mundo rural en una encrucijada en la que su propia supervivencia como espacio de reproducción social y económica dependerá en buena parte de las funciones social y ambiental de una agricultura abocada a ser multifuncional y del éxito de las políticas del segundo pilar de la PAC, a la sazón denominado Desarrollo Rural. En ese contexto, cobra una gran relevancia la función del mundo rural como espacio proveedor de energías renovables. El presente artículo se centra en esta nueva realidad y pretende, ante la escasez de estudios que de forma empírica analicen la contribución de la producción de energías renovables al desarrollo rural sostenible, dar unas pautas teóricas que de forma sistemática y genérica permitan llevar a cabo estudios empíricos que contrasten el papel que las energías renovables pueden jugar en el mundo rural.Peer reviewe

Editorial Special Issue: Public policies prompting sustainable transport in cities

This special issue focuses on public policies prompting sustainable transport in cities. Although the literature that analyses the behaviour of transport users in urban areas is abundant, it is still necessary to deepen on the analysis of the behaviour of these consumers, since the problems of unsustainability of urban mobility remain unsolved. From an Applied Economic Science point of view, this continues to be a field of maximum interest in which to advance. The 10 articles included in this special issue come to shed light to this topic

La política de empleo de la unión europea

Nadie duda que la política social jugará un papel importante en el futuro de la Unión Europea, si la idea del mercado único prevalece sobre la Europa de los ciudadanos. En cualquier caso, el problema del empleo ha estado presente desde los origenes de la Comunidad Económica Europea pero como un problema menor. Actualmente, ha llegado a ser un factor importante en la formación de la política económica general. Este estudio muestra un análisis crítico de las políticas comunitarias de empleo. Se estudian tres períodos diferentes: 1) los antecedentes de las políticas de empleo en la Comunidad que terminaría con el Tratado de Maastricht, el cual establece como objetivo promover un mayor nivel de empleo; 2) un segundo período en el cual el empleo es una prioridad en la construcción de una Europa integrada: el Tratado de la Unión; 3) nuevas acciones y procesos comunitarios para el empleo posteriores al Tratado de Amsterdam.________________________________It is difficult to believe that social policies will play an important part in the future in Europe, if the idea of the Europe of the market prevails on the Europe of the citizens. Nevertheless, the employment problem was present since the beginning of the European Economic Community, although as a minor problem. At present, it has become an important factor in the definition of the general economic policy. This paper presents a critical analysis of the Employment Community Policies. Three different periods are presented: l) the old employment policy in the Community that ends with the Maastricht Treaty that establishes the objective of promoting a higher level of employment; 2) a second period in which employment is a priority in order to build an Integrated Europe: The Union Treaty; and 3) new Community actions and processes for employment following Amsterdam Treaty

B2B platform for media content personalisation

This paper proposes a novel business model to support media content personalisation: an agent-based business-to-business (B2B) brokerage platform for media content producer and distributor businesses. Distributors aim to provide viewers with a personalised content experience and producers wish to en-sure that their media objects are watched by as many targeted viewers as possible. In this scenario viewers and media objects (main programmes and candidate objects for insertion) have profiles and, in the case of main programme objects, are annotated with placeholders representing personalisation opportunities, i.e., locations for insertion of personalised media objects. The MultiMedia Brokerage (MMB) platform is a multiagent multilayered brokerage composed by agents that act as sellers and buyers of viewer stream timeslots and/or media objects on behalf of the registered businesses. These agents engage in negotiations to select the media objects that best match the current programme and viewer profiles

Brokerage Platform for Media Content Recommendation

Near real time media content personalisation is nowadays a major challenge involving media content sources, distributors and viewers. This paper describes an approach to seamless recommendation, negotiation and transaction of personalised media content. It adopts an integrated view of the problem by proposing, on the business-to-business (B2B) side, a brokerage platform to negotiate the media items on behalf of the media content distributors and sources, providing viewers, on the business-to-consumer (B2C) side, with a personalised electronic programme guide (EPG) containing the set of recommended items after negotiation. In this setup, when a viewer connects, the distributor looks up and invites sources to negotiate the contents of the viewer personal EPG. The proposed multi-agent brokerage platform is structured in four layers, modelling the registration, service agreement, partner lookup, invitation as well as item recommendation, negotiation and transaction stages of the B2B processes. The recommendation service is a rule-based switch hybrid filter, including six collaborative and two content-based filters. The rule-based system selects, at runtime, the filter(s) to apply as well as the final set of recommendations to present. The filter selection is based on the data available, ranging from the history of items watched to the ratings and/or tags assigned to the items by the viewer. Additionally, this module implements (i) a novel item stereotype to represent newly arrived items, (ii) a standard user stereotype for new users, (iii) a novel passive user tag cloud stereotype for socially passive users, and (iv) a new content-based filter named the collinearity and proximity similarity (CPS). At the end of the paper, we present off-line results and a case study describing how the recommendation service works. The proposed system provides, to our knowledge, an excellent holistic solution to the problem of recommending multimedia contents

Media Brokerage: Agent-Based SLA Negotiation

Media content personalisation is a major challenge involving viewers as well as media content producer and distributor businesses. The goal is to provide viewers with media items aligned with their interests. Producers and distributors engage in item negotiations to establish the corresponding service level agreements (SLA). In order to address automated partner lookup and item SLA negotiation, this paper proposes the MultiMedia Brokerage (MMB) platform, which is a multiagent system that negotiates SLA regarding media items on behalf of media content producer and distributor businesses. The MMB platform is structured in four service layers: interface, agreement management, business modelling and market. In this context, there are: (i) brokerage SLA (bSLA), which are established between individual businesses and the platform regarding the provision of brokerage services; and (ii) item SLA (iSLA), which are established between producer and distributor businesses about the provision of media items. In particular, this paper describes the negotiation, establishment and enforcement of bSLA and iSLA, which occurs at the agreement and negotiation layers, respectively. The platform adopts a pay-per-use business model where the bSLA define the general conditions that apply to the related iSLA. To illustrate this process, we present a case study describing the negotiation of a bSLA instance and several related iSLA instances. The latter correspond to the negotiation of the Electronic Program Guide (EPG) for a specific end viewer
