Analyse de la consommation de bar et de daurade dans les pays méditerranéens de l' Union.

ABSTRACT. The overall objective of this study is to analyse the situation of the seabream and seabass market, in order to provide relevant information for designing sustainable development strategies. It is divided into two parts: the first is an aggregated study about the factors affecting consumption in the Mediterranean countries of the European Union, which concentrated 79.5% of the consumption of these species in 2005. The second part is more specific and studies the influence that awareness and attitude towards aquaculture has on consumption patterns and valuation of the species, factors that are to be taken into account when designing specific strategies for each market. This latter part is confined to the Spanish market, and therefore results cannot be extrapolated to others, but they may serve as reference given that Spain accounts for 18.6% of total seabream and seabass consumption in the European Union.RÉSUMÉ. L' objectif global de cette étude est d' analyser la situation du marché du bar et de la daurade, afin de fournir une information utile pour la mise au point de stratégies de développement durable. Elle est divisée en deux parties : la première est constituée par une étude agrégée sur les facteurs qui influencent la consommation dans les pays méditerranéens de l Union Européenne, qui ont concentré 79,5% de la consommation de ces espèces en 2005. La seconde partie est plus spécifique et examine l' influence que la sensibilisation et l' attitude vis-à-vis de l 'aquaculture présentent sur les tendances de connsommation et d 'appréciation de ces espèces, facteurs qui entrent en ligne de compte pour la conception de stratégies spécifiques à chaque marché. Cette dernière partie se limite au marché espagnol, et par conséquent les résultats ne peuvent pas être extrapolés à d 'autres marchés, mais ils peuvent toutefois servir de référence étant donné que l' Espagne représente 18,6% de la consommation totale de bar et de daurade au sein de l' Union Européenne

Technical efficiency of sea bass and sea bream farming in the Mediterranean Sea by European firms: A stochastic production frontier (SPF) approach

In recent years, European producers of cultured sea bass and sea bream have experienced a highly competitive market with low prices that have caused profitability challenges. An important factor of economic competitiveness for firms is to produce efficiently. In this paper, technical efficiency of European producers of cultured sea bass and sea bream is evaluated for the period 2008-2017 using the stochastic production frontier (SPF) approach. In addition, the effect of a set of specific-firm factors on firms' efficiency is investigated. The majority of firms in the sample were found to have a technical efficiency over 90% with Cypriot and Greek firms being, on average, the most efficient. We also found evidence that the technical efficiency of these firms is positively related to their size. Moreover, the high degree of average efficiency means that further production growth requires innovations that move up the production frontier

An LRP6 mutation (Arg360His) associated with low bone mineral density but not cardiovascular events in a caucasian family

We present a family with a rare mutation of the LRP6 gene and for the first time provide evidence for its association with low bone mineral density. Introduction: The Wnt pathway plays a critical role in bone homeostasis. Pathogenic variants of the Wnt co-receptor LRP6 have been associated with abnormal skeletal phenotypes or increased risk of cardiovascular events. Patient and methods: Here we report an index premenopausal patient and her family carrying a rare missense LRP6 pathogenic variant (rs141212743; 0.0002 frequency among Europeans). This variant has been previously associated with metabolic syndrome and atherosclerosis, in the presence of normal bone mineral density. However, the LRP6 variant was associated with low bone mineral density in this family, without evidence for association with serum lipid levels or cardiovascular events. Conclusion: Thus, this novel association shows that LRP6 pathogenic variants may be involved in some cases of early-onset osteoporosis, but the predominant effect, either skeletal or cardiovascular, may vary depending on the genetic background or other acquired factors.Funding: Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Natur

¿Es viable el fútbol de élite sobre césped artificial? El caso FIFA Women World Cup™

El objetivo de esta investigación es comparar variables de juego en césped natural y césped artificial en el alto rendimiento deportivo para comprobar en qué medida afecta al rendimiento deportivo y de gestión de la instalación. Se analizaron 283 jugadoras que participaron en las Copas Mundiales Femeninas de la FIFA de 2011 (césped natural) y 483 en la de 2015 (césped artificial). Para este estudio se tomaron como referencia variables relacionadas con los pases, toques, regates y entradas. Se utilizó la U de Mann-Whitney para contrastar las diferencias entre ambos torneos. Los resultados obtenidos en este estudio demuestran que el porcentaje de éxito respecto al total de acciones de rendimiento técnico es mejor en césped artificial (Mundial 2015) en gran parte de las variables estudiadas (salvo en regates), tanto totales como por posiciones.The aim of this research is to compare the game play variables in artificial turf vs. natural turf at high performance level and to assess in which manner it affects to the sport performance and the management of the facility. We analyzed 283 women players who participated in the FIFA® World Championship of 2011 (natural grass) and 483 women players of 2015 (artificial turf). Variables measured were passes, touches, dribbles, and tackles. We used U of Mann-Whitney test to evaluate the differences between two tournaments. Results showed that the success percentage of all game play actions is higher in artificial turf (World Championship 2015) in most of variables analyzed (except dribbles), in total and depending on player position
