Based on nine parameters that establish the changes in the local cultural policy and the cultural space in the great structural changes resulting from the digital transition and the large flows of the global economy, the author examines thirteen factors that entail keys to the progression of local culture. Among them he points out the selective discernment, the breaking of the limitations of public attendance and participation, the importance of education, the new creative circuits, the best use of personal cultural capital, the collaborative culture, the recognition of otherness or the importance of interculturality and professional ethics of cultural intermediation. ; A partir de nueve parámetros que establecen los cambios habidos en la política cultural local y el espacio de lo cultural en los grandes cambios estructurales resultantes de la transición digital y de los grandes flujos de la economía global, este artículo examina trece factores que conllevan claves para la progresión de la cultura local. Entre ellos señala el discernimiento selectivo, la ruptura del techo de públicos, la importancia de la educación, los nuevos circuitos creativos, el mejor uso de capital cultural personal, la cultura colaborativa, el reconocimiento de la otredad o la importancia de la interculturalidad y de la deontología profesional de la intermediación cultural.

Local Cultural Policies: Looking to the Future Abstract: Based on nine parameters that establish the changes that have taken place in local cultural policy and the cultural space in the great structural changes resulting from the digital transition and the great flows of the global economy, this article examines thirteen factors that entail keys to the progression of local culture. Among them, he points out the selective discernment, the breaking of the public ceiling, the importance of education, the new creative circuits, the best use of personal cultural capital, the collaborative culture, the recognition of otherness or the importance of interculturality and the professional deontology of cultural intermediation. Keywords: universal access, citizen empowerment, cultural democracy, cultural revolution, education-culture, interculturality, cultural rights, Agenda 21, creation factories, cultural networks, competence frameworks.

In real-time systems, the techniques to derive bounds to the contention tasks can suffer in multicore build on resource quota monitoring and enforcement. Existing techniques track and bound the number of requests to hardware shared resources that each core (task) is allowed to perform. In this paper we show that current software-only solutions work well when there is a single resource and type of request to track and bound, but do not scale to the more general case of several shared resources that accept different request types, each with a different associated latency. To handle this (more general) case, we propose low-overhead hardware support called Maximum-Contention Control Unit (MCCU). The MCCU performs fine-grain tracking of different types of requests, preventing a core to cause more interference on its contenders than budgeted. In this process, the MCCU also helps verifying that individual requests duration does not exceed their theoretical bounds, hence dealing with scenarios in which requests can have an arbitrarily large duration. ; This work has been partially supported by the Spanish Ministry of Economy and Competitiveness (MINECO) under grant TIN2015-65316-P, the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation programme (grant agreement No. 772773) and the HiPEAC Network of Excellence.

Manycores are capable of providing the computational demands required by functionally-advanced critical applications in domains such as automotive and avionics. In manycores a network-on-chip (NoC) provides access to shared caches and memories and hence concentrates most of the contention that tasks suffer, with effects on the worst-case contention delay (WCD) of packets and tasks' WCET. While several proposals minimize the impact of individual NoC parameters on WCD, e.g. mapping and routing, there are strong dependences among these NoC parameters. Hence, finding the optimal NoC configurations requires optimizing all parameters simultaneously, which represents a multidimensional optimization problem. In this paper we propose NoCo, a novel approach that combines ILP and stochastic optimization to find NoC configurations in terms of packet routing, application mapping, and arbitration weight allocation. Our results show that NoCo improves other techniques that optimize a subset of NoC parameters. ; This work has been partially supported by the Spanish Ministry of Economy and Competitiveness under grant TIN2015- 65316-P and the HiPEAC Network of Excellence.
