Dificuldades e desafios na incorporação de práticas arquitectónicas

La arquitectura software se ha convertido en un activo clave en las organizaciones desarrolladoras de software, pues permite alcanzar las metas de calidad y lograr productos fácilmente evolucionables. Sin embargo, en las pequeñas organizaciones, la arquitectura de software normalmente es una idea vaga sobre la estructura de la solución.

Proposing an analysis of cultural policies and their impact on the economic development of countries: the case of Germany and Spain

[EN] This article aims to describe the analitycal framework in which it will be analyzed whether the cultural policies of Germany and Spain are moving towards knowledge and innovation, and how these policies affect the economic development of their countries. The methodology that we will apply will be the Qualitative Comparative Analysis; the data that we will use will be taken from the Compendium of Public Policies and Trends. We have decided to analyze Germany and Spain cases because they have the following requirements: Being a member of the OECD, member of the Compendium of Cultural Policies and Trends. In addition, Germany has been chosen for being a benchmark in terms of economic development. This research is important because cultural and creative industries, as well as public policies on them, have evolved in recent years, and new trends in research on cultural policies are moving towards the concepts of knowledge and innovation. The European Innovation Scoreboard 2021 affirms the relationship between the most innovative countries and the economic development of these countries. Therefore, the objective of this research is to analyze whether the cultural policies of Germany and Spain are moving towards knowledge and innovation, and how these policies affect the economic development of their countries.Gomez Reyes, FM.; Catalá Pérez, D.; Miguel Molina, MRD.; Manrique-Hernández, E.

Presentation

El pasado mes de abril iniciamos una nueva etapa en Çédille, representada principalmente por su traslado a la plataforma Open Journal System (OJS) de la Universidad de La Laguna, así como por la renovación y reasignación de competencias del Consejo de Redacción. Durante este tiempo, hemos tenido que adaptarnos, experimentar y comprender, pacientemente, el funcionamiento de esta nueva herramienta que es OJS. Ello ha supuesto, en algunos casos, que se hayan producido determinadas dificultades de comunicación con nuestros lectores y evaluadores, o que se hayan ocasionado pequeños retrasos en la gestión de la revista. Como nuestros seguidores saben, muy recientemente hemos sufrido, además, un ataque informático que no solo impidió el acceso a la plataforma durante varios días (justo en el momento final de producción de este número), sino que obligó a trasladar nuestro sitio web a otro servidor y a implementar nuevas medidas de seguridad. Afortunadamente, gracias al buen hacer y profesionalidad de Juan Ascanio Amigó, asesor técnico de OJS para la Universidad de La Laguna, hemos logrado salir airosos de los problemas, complicaciones y secuelas que nos hemos ido encontrando en este tiempo. En este número que ahora ve la luz contamos con treinta y cuatro contri-buciones que superan, en total, las setecientas páginas. Así, Amelia Gamoneda Lanza y Francisco González Fernández se han encargado de coordinar una nueva entrega –la undécima– de la serie «Monografías», donde han reunido una ..

Suppression of Λ(1520) resonance production in central Pb–Pb collisions at √sNN = 2.76 TeV

The production yield of the Λ(1520) baryon resonance is measured at mid-rapidity in Pb-Pb collisions at sNN−−−√ = 2.76 TeV with the ALICE detector at the LHC. The measurement is performed in the Λ(1520)→pK− (and charge conjugate) hadronic decay channel as a function of the transverse momentum (pT) and collision centrality. The pT-integrated production rate of Λ(1520) relative to Λ in central collisions is suppressed by about a factor of 2 with respect to peripheral collisions. This is the first observation of the suppression of a baryonic resonance at the LHC and the first 3σ evidence of Λ(1520) suppression within a single collision system. The measured Λ(1520)/Λ ratio in central collisions is smaller than the value predicted by the statistical hadronisation model calculations. The shape of the measured pT distribution and the centrality dependence of the suppression are reproduced by the EPOS3 Monte Carlo event generator. The measurement adds further support to the formation of a dense hadronic phase in the final stages of the evolution of the fireball created in heavy-ion collisions, lasting long enough to cause a significant reduction in the observable yield of short-lived resonances

Direct photon elliptic flow in Pb–Pb collisions at √sNN = 2.76 TeV

The elliptic flow of inclusive and direct photons was measured at mid-rapidity in two centrality classes 0-20% and 20-40% in Pb-Pb collisions at sNN−−−√ =2.76 TeV by ALICE. Photons were detected with the highly segmented electromagnetic calorimeter PHOS and via conversions in the detector material with the e+e− pairs reconstructed in the central tracking system. The results of the two methods were combined and the direct photon elliptic flow was extracted in the transverse momentum range 0.9<pT<6.2 GeV/c. We test the hypothesis vγ,dir2≡0 for 0.9<pT<2.1 GeV/c and obtain a significance of 1.4σ for the 0-20% class and 1.0σ for the 20-40% class. A comparison to RHIC data shows a similar magnitude of the measured elliptic flow, while hydrodynamic and transport model calculations predict a smaller flow than observed
