    The arrival of a new form of coronavirus at the end of 2019 and its subsequent expansion to multiple countries has already caused severe consequences whose final extent we are unfortunately still far from seeing. In our geographical context, Italy has been particularly affected by this threat. In such circumstances, it is worth asking what the EU could do to help any of its Member States (MS) to cope with such a situation. This paper will try to answer it. To this end, we will focus on the most important legal instrument: the so-called, “Solidarity Clause” and the most relevant political tool, the Integrated Political Crisis Response arrangements (IPCRs).This work was supported by Eusko Jaurlaritza [grant number Ayudas a grupos de investigación IT-1066-16]; H2020 Science with and for Society [grant number GRANT AGREEMENT NUMBER — 788039 — PANELFIT]

    The growing adoption of Model Driven Development (MDD) in companies during last decade arises some model interchange problems. Companies need support to interchange models and reuse parts of them for developing new projects. Traditional tools for model edition and model interchange have different performance issues related to the models storage. There are mainly two styles to organize the persistence of models into repositories: a complex and large model or a large amount of small models. This last approach is common in companies that generate software from models. In this paper, we analyse performance properties of different persistence technologies to store small/medium-scale models, the analysis results should be considered in the design of model repositories in the cloud. With this aim, we have designed and developed a generic architecture to evaluate each persistence technology under similar situations

    Este trabajo se ocupa de la recategorización léxica que experimentan algunos nombres individuales cuando se interpretan como colectivos en determinados contextos; el proceso se vincula a la existencia de un rasgo sub-léxico en la definición del nombre individual, potencialmente capacitado para ser coaccionado y desencadenar un cambio de tipo semántico en el nombre. El artículo defiende, pues, una definición flexible y permeable para las unidades léxicas y para las clases en que se agrupan en función de su significado, y una concepción del cambio regular y productiva, ligada al contexto, y restringida por la propia potencialidad de la palabra. La hipótesis se inserta en el modelo del Lexicón Generativo (Pustejovsky & Batiukova, 2018), según el cual la entrada de las palabras en el lexicón mental es un conjunto infraespecificado de rasgos o fragmentos de contenido, distribuidos de forma jerárquica y muy estructurada, y capacitados para especificarse en los distintos contextos. El modelo presupone además la existencia de un conjunto de mecanismos generativos, entre ellos, el de coacción, al que aquí se atribuye la recategorización léxica de los nombres individuales como colectivos. El análisis sub-léxico propuesto vincula el cambio de categoría léxica al contexto en que se produce la coacción de un rasgo; por tanto, prevé que, fuera de ese contexto, la palabra pertenece a la clase a la que originariamente está adscrita; el comportamiento gramatical de los nombres individuales objeto de este estudio confirma la propuestaThis study deals with the process of lexical recategorization that some individual nouns undergo when interpreted as collective in certain contexts. This process is linked to the presence of a sub-lexical feature in the definition of individual nouns, which can be coerced and trigger a change in their semantic typing. Thus, this paper advocates a flexible and permeable definition of lexical items and semantic classes of lexical items, and a regular and productive conception of lexical change, which is determined by the context and constrained by the potential of the word itself. This hypothesis is framed within the Generative Lexicon model (Pustejovsky & Batiukova, 2018), where the entries in the mental lexicon are underspecified sets of semantic features or fragments structured hierarchically and potentially able to become specified in different contexts. In addition, this model assumes the existence of a set of generative mechanisms. One of them is coercion, which is made responsible for recategorizing individual nouns as collective in this study. In the sublexical analysis here expounded, the change of lexical category is related to the context wherein coercion takes place. Therefore, it is assumed that, outside this context, the word belongs to its original class. The grammatical behavior of the individual nouns confirms this hypothesi

    Inventory and assessment of fluvial potholes to promote geoheritage sustainability (Miño River, NW Spain)

    The Miño is the most important river in the NW Iberian Peninsula. When it flows through Ourense town (Spain), the attractiveness of the thermal springs hides the importance of the fluvial potholes developed over bedrock. These forms reflect the strength of erosion processes, linked to fluvial incision over time. Potholes have an environmental, didactic, socio-economic and cultural potential. In order to promote their integration within territorial heritage, this research is focused on a place-based knowledge and practice. This study aimed to define the meanings and interests of fluvial potholes, regarding their sustainable uses as georesources and offering fit information for the key social actors to assist territorial development. An inventory of sculpted forms was carried out in an urban reach of the Miño River. After the site diagnosis and form characterisation, a set of fluvial potholes (82 cases) was identified within the thermal area. The assessment of the geomorphological and use/management interests delivered their values as resources for territorial sustainability. Ten potholes, selected from a preliminary list and identified through the methodology, have a potential for education, leisure and recreation. Actions designed to raise awareness of the interests and values of these geodiversity components are also presented.Xunta de Galicia | Ref. ED481A-2015/410Universidade de Vigo | Ref.

    Growth of sculpted forms in bedrock channels (Mino River, Northwest Spain)

    Get PDF
    A total of 216 sculpted forms were registered on the granitic bedrock of the Miño River, northwest Iberian Peninsula. Analysis of in situ measurements (length, width and depth) revealed three general type-sets: incipient forms, longitudinal furrows and circular pot-holes. Maximum depth and upper radius (at the incision surface) were identified as key variables to mathematically determine the growth rate in each set. Three regression models are presented revealing that the development of the forms depends on a power law explaining their size and shape. Morphological and dimensional thresholds were established to better identify stages from incipient active growth) and inherited (stationary growth) form

    Research, management and water values in today’s world

    This volume of the series Perspectives of Water tries various aspects about the research, planning of uses, management and socio-cultural values of aquatic systems in the contemporary period. The contributions induding analyse the relationship between water and human communities in the workl today from scientific, political, social and cultural perspectives. Water is a natural good indispensable for any human activity whose value must be investigated, known and disseminated (European Council, 1968) taking account its role as a resource for the well-being in the international human rights framework (World Health Organization, 2003; United Nations, 2010). The protection, improvement and rational management of aquatic systems are also goals of sustainable development into the future, defined by Agenda 2030 (United Nations, 2015) where education is seen as a process that favours the creation of innovative solutions for current problems of water. At the same time, the generations of actions for sustainability, especially directed toward the integrated management of water resources, are promoted by the declaration of the 2018-2028 Decade of Action by the Water (United Nations, 2016). In Europe, both protection and sustainable use and management of the waters (continental,transitional, coas tal and groundwater) are regulated by the Directive 2000/60/EC in order to prevent their pollution, protect and/or improve their status, mitigate the effects of floods and droughts, and hdp to ensure a long-term equitable provision. This impulse from the institutional sphere represents an opportunity to prioritize the importance of water as a resource of humanity and highlights the relevance of the ítem to encourage the exchange of ideas and collaboration between researchers, managers and social groups particularly interested in aquatic systems

    Un estudio exploratorio para testar los sedimentos atrapados por marmitas de erosión en ríos sobre roca como indicadores ambientales (NO Macizo Ibérico)

    The capacity of fluvial potholes to trap sediments, together with the geochemical analysis of their stored sediments for environmental assessment, is an overlooked research topic in small bedrock rivers. The present exploratory study is focused on this issue. It was developed in a small river over rock, in the inland territory of Galicia (NW Iberian Peninsula). The study started from an analysis of the inventoried fluvial potholes to identify suitable forms for sampling, and the collection of sediment samples within them. After this, the determination of the grain texture, mineralogy and content of major and trace elements in sediments were carried out. Potholes with maximum vertical depth from 25 cm to 1 m, located in central and sidewall sectors of the bedrock channel, provided the best conditions for sediment sampling. The sediments collected from six potholes showed predominance of coarse-medium grain size and sand fraction. The rough contents of the major and even trace elements are related with the nature of the more refractory minerals of the bedrock. An adequate sampling strategy, considering grain-size fractions, show potential to use trace elements as environmental indicators.La capacidad de las marmitas fluviales para atrapar sedimentos junto con el análisis de los mismos para la evaluación ambiental es un tema de investigación poco estudiado en el caso de pequeños ríos sobre roca. El estudio exploratorio que se presenta, desarrollado en un pequeño río sobre roca del interior de Galicia (noroeste de la Península Ibérica), está centrado en esta cuestión. El estudio partió del análisis de las marmitas fluviales inventariadas con el objetivo de identificar las formas adecuadas para el muestreo y la recolección de sedimentos en su interior. A continuación, se determinó la granulometría, mineralogía y el contenido de elementos mayoritarios y de elementos traza en los sedimentos. Las marmitas fluviales con profundidad máxima vertical desde 25 cm hasta 1 m, localizadas en el sector central y lateral del canal, presentaron las mejores condiciones para el muestreo de sedimentos. En los sedimentos recolectados en seis marmitas predomina el tamaño de grano grueso-medio y la fracción arenosa. El contenido de elementos mayoritarios y traza está relacionado con la naturaleza de los minerales más refractarios de la roca. Mediante una estrategia de muestreo adecuada, teniendo en cuenta las fracciones granulométricas, muestran potencial en el uso de los elementos traza como indicadores ambientales
