Reconstrucción de un flujo de derrubios: el desastre de Marines (Valencia) de octubre de 1957
2021
espanolEn la manana del 14 de octubre de 1957 una masa compuesta principalmente por bloques y fango procedente de la vertiente oeste de las crestas del Rodeno (Sierra Calderona) asolo la mayor parte del casco urbano de Marines (Valencia), causando 6 victimas mortales y numerosos danos materiales. A partir de la consulta de documentacion de archivo, de la revision de diversas fotografias, del examen de los depositos sedimentarios y de los testimonios de algunos supervivientes, este trabajo ensaya una reconstruccion del episodio y una interpretacion geomorfologica del movimiento de masa. Los materiales analizados han permitido elaborar una cartografia detallada de los procesos y formas del ev…
Yielding of a quartz sand from saturated to dry state
2020
The paper presents the results of an experimental work where we analyse the behaviour of an unsaturated quartz sand in a wide range of degree of saturation (from saturated to dry state). The possibility of anticipating the hydro-mechanical behaviour of the soils when they approach the dry state is fundamental in many areas. An extensive experimental program, including controlled-suction and constant water content oedometric tests, was carried out to deeply analyse the water retention behaviour and the relationship between the yield stress and suction (Loading-Collapse curve). All elasto-plastic models provide a monotonically increase of the yield stress with suction. This assumption implies…
A physical model for the interaction between unsaturated soils and retaining structures
2020
Temporary and permanent retaining structures interact with soils that are usually in unsaturated conditions. In this work, a 1g-scale physical model is presented to investigate the interactions between retaining walls and unsaturated soils. The physical model is equipped with a water-filled hydraulic cylinder connected to a pressure-volume controller to measure the horizontal component of the later earth thrust and high capacity tensiometers to measure soil matric suction. A system of low-friction linear guideways has been installed at the base of the wall-model. The failure surface is observed through a 3 cm thick glass wall on one side of the container. A series of images are acquired dur…

Fish Welfare in Aquaponic Systems: Its Relation to Water Quality with an Emphasis on Feed and Faeces—A Review
2017
Aquaponics is the combination of aquaculture (fish) and hydroponic cultivation of plants. This review examines fish welfare in relation to rearing water quality, fish feed and fish waste and faeces to develop a sustainable aquaponic system where the co-cultured organisms, fish, bacteria in biofilters and plants, should be considered holistically in all aquaponics operations. Water quality parameters are the primary environmental consideration for optimizing aquaponic production and for directly impacting fish welfare/health issues and plant needs. In aquaponic systems, the uptake of nutrients should be maximised for the healthy production of the plant biomass but without neglecting the best…
Flexicurity as a measuring leakage protection of workers: between "social pollution" and "total security"
2012
Was not the labour problem the same everywhere? The paper attempts to answer this question by proposing a re-interpretation of flexicurity through the comparison with the economic concepts of externalities and distortion of competition. After a methodological and epistemological premise, based on a multidisciplinary literature, the paper - critically addresses the origins of flexicurity and argues that it lacks an archetypical definition, especially in the formulation of the EU Commission. Hence, the paper considers flexicurity as any balance between flexibility and security and, therefore, proposes ordering any set of contracts, providing the same balance and with the same regulatory fr…
EU Cultural Security Law in an Educational Context
2021
Cultural security is a comprehensive notion that has gained much attention in the recent cultural heritage debates. In terms of the EU, it encapsulates cultural heritage destruction and protection in armed conflicts, post-war cultural heritage management, restitution, illicit traffic of cultural property, cultural diversity, and intercultural dialogue. The article aims to present how cultural security matters appear in the EU legal system and policy. The authors argue that cultural security is present in different policies regarding cultural property and the fight against illicit trafficking, as well as in EU external cultural relations. Digitization in the cultural sector constitutes a cha…
The importance of strategic leadership in cyber security : Case of Finland
2019
Cyber security has become one of the biggest priorities for businesses and governments. Streamlining and strengthening strategic leadership are key aspects in making sure the cyber security vision is achieved. The strategic leadership of cyber security implies identifying and setting goals based on the protection of the digital operating environment. Furthermore, it implies coordinating actions and preparedness as well as managing extensive disruptions. The aim of this paper is to define what is strategic leadership of cyber security and how it is implemented as part of the comprehensive security model in Finland. The paper also asks (and answers) how the strategic leadership of cyber secur…
Reconstructing Care Professionalism in Finland
2015
The public sector plays a special role in the Nordic welfare states through its commitment to the principle of universalism, and in relation to social security and publicly funded services in education, health and care (Rostgaard 2002). In the 21st century, the impact of economic austerity on public resources and a rapid aging of the population have forced welfare states to undergo an extreme reform. In Finland, the reform has meant streamlining the state, restraining public expenditure and recalibrating the universalistic ideals behind the Nordic welfare state model, as well as introducing new management models (Pollitt & Bouckaert 2011). The managerial reforms implemented in Finland have …
Charismatic Leaders in a New Perspective: Reality in Estonia and Italy
2020
The purpose of this explorative study is to put the existing theories on charismatic political leadership in a current post-web media context. It also seeks to better understand why “charismatic politicians” seem to have success in present-day cyber politics. The paper considers political charisma in a Weberian perspective and aims to explain what elements it includes in a current electoral environment characterized by a fast-changing media landscape. The paper places the existing theoretical models in the context of two European societies, by comparing Estonia and Italy as case studies. Estonia, a small ex-Soviet country has emerged in recent years as an advanced e-society with highly “int…
