Las autoridades de regulación audiovisual en España: panorámica y perspectivas del control de la pluralidad
2016
Las autoridades de regulación audiovisual son un instrumento de control, entre otras cosas, de la pluralidad informativa de las televisiones públicas. Así lo reconocen diversas leyes a nivel comunitario y español. En nuestro país, la asunción de la autoridad en materia audiovisual por parte de la Comisión Nacional de los Mercados y la Competencia (CNMC), nos ha incorporado tarde y mal a nuestro entorno europeo, donde son habituales estos consejos. También en las diferentes Comunidades Autónomas, hay un déficit regulatorio que hace que tan sólo Catalunya y Andalucía estén dotadas de este instrumento. En el artículo estudiaremos el “estado del arte” sobre la cuestión, para poder valorar nues…
12S rRNA mitochondrial gene as marker to trace Sicilian mono-species dairy products
2016
Abstract For a rapid, specific and sensitive identification of cows', ewes' and goats' milk in mono-species Sicilian dairy products, species-specific duplex-PCR protocol was applied. DNA samples from blood and experimental cheeses of Sicilian autochthonous breeds were extracted to amplify the 12S rRNA (and part of 16S rRNA in case of Ovis aries ) mitochondrial species-specific gene fragment. The use of species-specific primers for Bos taurus , Capra hircus and Ovis aries species, after electrophoresis on agarose gel, yielded fragments of 256 bp, 326 bp and 172 bp, respectively. Amplification by duplex - PCR of DNA pools from two species showed detection thresholds of 0.1% of “contaminant” D…
ASSESSMENT OF ECOSYSTEM SERVICES FOR PLANNING OF GREEN INFRASTRUCTURE AT THE REGIONAL LEVEL
2019
Ecosystem services (ES) are defined as the benefits that human beings derive from ecosystem functions. Assessment and mapping of these benefits are crucial for sustainable environmental planning and future natural capital. Green infrastructure (GI) is natural or semi-natural territories that provide wide range of ES. Human affected ecosystems tend to fail to provide certain sets of ES due to the trade-offs among those services, which could be mitigated through implementation of GI. Mapping of ES, as well as assessing the interactions among various ES and analysing their supply potential’s cold/hot spots considerably enhances and substantiates the planning process of GI, particularly at the …
The household location in multicenter urban spaces
1991
In multicenter urban spaces, the household location problem is to find an optimal location taking into account the locations of several economic centers.In this article, we show that the usual model, maximizing a residential utility under a budget spatial constraint, can’t give a satisfactory solution.So, we construct a fuzzy spatial model, including imprecision in consumer’s behavior. This model allows us to find an optimal location in a multicenter urban setting. Then, an empirical study illustrates the performances of the fuzzy model.
European leaders unmasked: Covid-19 communication strategy through Twitter
2020
[EN] The coronavirus disease Covid-19 (SARS-CoV-2) pandemic is exacting a huge toll on individuals, families, communities, and societies across the world. The study of public communication is a key aspect for slowing the spread of the virus and therefore reducing the death rate. This article analyses political leaders' crisis communication during the Covid-19 pandemic of the most affected European countries, Boris Johnson (United Kingdom), Emmanuel Macron (France), Pedro Sanchez (Spain) and Giuseppe Conte (Italy), in addition to Tedros Adhanom as a representative of the World Health Organisation (WHO) and Ursula Von der Leyen President of the European Union (EU). The study focuses on the vi…
Dynamics of the caring family
2003
When several individuals simultaneously provide for offspring, as in families, the effort of any one individual will depend on the efforts of the other family members. This conflict of interest among family members is made more complicated by their relatedness because relatives share genetic interest to some degree. The conflict resolution will also be influenced by the differences in reproductive value between breeders and helpers. Here, we calculate evolutionarily stable provisioning efforts in families with up to two helpers. We explicitly consider that the behavioral choices are made in a life-history context, and we also consider how group sizes change dynamically; this affects, for ex…
Pinch technique and the Batalin-Vilkovisky formalism
2002
In this paper we take the first step towards a non-diagrammatic formulation of the Pinch Technique. In particular we proceed into a systematic identification of the parts of the one-loop and two-loop Feynman diagrams that are exchanged during the pinching process in terms of unphysical ghost Green's functions; the latter appear in the standard Slavnov-Taylor identity satisfied by the tree-level and one-loop three-gluon vertex. This identification allows for the consistent generalization of the intrinsic pinch technique to two loops, through the collective treatment of entire sets of diagrams, instead of the laborious algebraic manipulation of individual graphs, and sets up the stage for the…

Ficción audiovisual y procesos de percepción en estudiantes universitarios de Argentina y España. Una investigación empírica. S
2014
Esta investigación descubre las diferencias en la percepción audiovisual en jóvenes estudiantes, mediante la evaluación del impacto afectivo o cambio de estado de ánimo que muestra el observador en relación con un capítulo de una ficción audiovisual conocida. Un grupo de estudiantes de Ciencias de la Comunicación procedentes de la Universidad Austral de Buenos Aires (Argentina) y de la Universidad de Valencia (España) se han sometido a cuestionarios analíticos pre-test y post-test sobre un capítulo de la serie de ficción “The Walking Dead”.
The Cyclicality of Bank Credit Losses and Capital Ratios under Expected Loss Model
2023
We model the evolution of stylised bank loan portfolios to assess the impact of IFRS 9 and US GAAP expected loss model (ECL) on the cyclicality of loan loss provisions (LLPs), realised losses and capital ratios of banks, relative to the incurred loss model of IAS 39. We focus on the interaction between the changes in LLPs charges (the flow channel) and stocks (the stock channel) under ECL. Our results show that, when GDP growth doesn’t demonstrate high volatility, ECL model smooths the impact of credit losses on profits and capital resources, reducing the pro-cyclicality of capital and leverage ratios, especially under US GAAP. However, when GDP growth is highly volatile, the large differen…
