El artículo 18 del estatuto de los trabajadores italiano a la luz de las últimas reformas laborales
2015
En las siguientes líneas se realizará un somero repaso sobre las principales las modificaciones de la disciplina italiana de los despidos individuales recogida en el artículo 18 del Estatuto de los Trabajadores italiano, introducidas por las últimas reformas laborales. En ellas se constará el impacto de dichas reformas en el cuadro legislativo de referencia, viéndose reducida la posibilidad de readmisión del trabajador en el caso de despido individual improcedente. Además se harán unos apuntes críticos sobre el concepto de flexsecurity, de cual se destaca una gran inflación en el presente contexto de crisis económica. This paper examines the amendments made to the Italian regulation of indi…
Analysis of the Relationship Between Context and Solution Plan in Modelling Tasks Involving Estimations
2021
In this chapter we analyse students’ written solution plan of a sequence of modelling tasks involving estimations. Our research objective is to statistically analyse whether there is a relation between the solution plan and the characteristics of the context of the real estimation task. From previous work, we have identified some task variables that are directly related to the context. In this study we have designed a sequence of modelling tasks and we have analysed the productions of N = 224 Spanish pre-service primary school teachers. The results show that there is a relationship between the variables of the task and the solution plan used by the students in each case. From the results of…
Evaluating the extent of patient-centred care in a selection of ESC guidelines
2019
AIMS: Patient-centred care (PCC) is the cornerstone for healthcare professionals to promote high quality care for patients with cardiovascular conditions. It is defined as 'Providing care that is respectful of, and responsive to, individual patient preferences, needs and values, and ensuring that patient values guide all clinical decisions'. PCC can improve patient outcomes and allow patients and healthcare professionals to manage care collaboratively using best available evidence. However, there is no clear understanding how extensively guidelines incorporate PCC recommendations. The aim of the study was to evaluate the incorporation of PCC into a selection of guidelines published by the E…
The Economics of Monetary Union: The Theory of Optimum Currency Areas
2013
In the 1960s, the theory of Optimum Currency Areas (OCAs) emerged as a by-product of the theoretical debate between fixed and flexible exchange rates. The OCAs approach singles out an economic characteristic to define an economic domain where there is exchange rate fixity erga intra, while there is exchange rate flexibility erga extra. In an optimum currency area, exchange rates fixity prevails internally without any type of internal or external disequilibrium. Each single characteristic ensures that floating or regular adjustments in nominal exchange rates are neither necessary, efficient nor desirable for stabilisation purposes. The literature proposes several economic criteria: factor mo…
Firing characteristics of vestibular nuclei neurons in the alert monkey after bilateral vestibular neurectomy
1992
After destruction of the peripheral vestibular system which is not activated by moving large-field visual stimulation, not only labyrinthine-ocular reflexes but also optokinetic-ocular responses related to the "velocity storage" mechanism are abolished. In the normal monkey optokinetic-ocular responses are reflected in sustained activity changes of central vestibular neurons within the vestibular nuclei. To account for the loss of optokinetic responses after labyrinthectomy, inactivation of central vestibular neurons consequent on the loss of primary vestibular activity is assumed to be of major importance. To test this hypothesis we recorded the neural activity within the vestibular nuclea…
Remote sensing of sun-induced chlorophyll fluorescence at different scales
2014
In this contribution we present activities and selected results obtained in recent studies and campaigns conducted in the context of the FLuorescence EXplorer (FLEX) mission. FLEX is a candidate mission for the ESA 8th Earth Explorer and large efforts are currently dedicated to the development of an implementation scheme for an accurate mapping of fluorescence from the selected spaceborne sensor and mission configuration. Field and airborne data collected in different experimental campaigns, together with simulated data, have been used to demonstrate the feasibility of fluorescence retrievals and the potential of exploiting high spatial resolution fluorescence maps for a better understandin…
Development of atmospheric correction algorithms for very high spectral and spatial resolution images: application to SEOSAT and the FLEX/Sentinel-3 …
2018
Advanced high spectral and spatial resolution imager spectrometers on board new generation of Earth Observation missions bring new exciting opportunities to the remote sensing scientific community. However, this progress goes hand in hand with new challenges. The exploitation of data acquired from these family of advanced instruments requires new processing algorithms able to deal with these particularities. As part of this evolution, atmospheric correction algorithms - a mandatory processing step applied prior to the Earth surface reflectance data exploitation - must be adapted or reformulated, thereby paying special attention to how atmospheric effects disturb the acquired signal in the s…
Bayesian Unification of Gradient and Bandit-based Learning for Accelerated Global Optimisation
2017
Bandit based optimisation has a remarkable advantage over gradient based approaches due to their global perspective, which eliminates the danger of getting stuck at local optima. However, for continuous optimisation problems or problems with a large number of actions, bandit based approaches can be hindered by slow learning. Gradient based approaches, on the other hand, navigate quickly in high-dimensional continuous spaces through local optimisation, following the gradient in fine grained steps. Yet, apart from being susceptible to local optima, these schemes are less suited for online learning due to their reliance on extensive trial-and-error before the optimum can be identified. In this…
Effect of FRP strengthening on the flexural behaviour of calcarenite masonry walls
2017
The use of fiber-reinforced polymers (FRP) for structural strengthening has become increasingly popular in recent years. Several applications of FRP have been proposed and applied, depending on the target of the technique, kind and/or material of the structural member. In particular, because of their great tensile strength, FRP materials are commonly used to enhance the out-of-plane behaviour of masonry walls, allowing to increase their strength, ductility and improving safety against overturning. For these reasons, FRP laminates are often applied in vulnerable ancient buildings in seismic areas to reinforce façades and walls with poor structural features. However, some issues arise when a…
Defining and measuring the network flexibility of humanitarian supply chains: insights from the 2015 Nepal earthquake
2019
International audience; The efficient and effective response to disasters critically depends on humanitarian supply chains (HSCs). HSCs need to be flexible to adapt to uncertainties in needs, infrastructure conditions, and behavior of other organizations. The concept of ‘network flexibility’ is, however, not clearly defined. The lack of an unanimous definition has led to a lack of consistent understanding and comparisons. This paper makes a threefold contribution: first, it defines the concept of network flexibility for HSC in the context of sudden onset disasters. Second, it proposes a framework to measure network flexibility in HSCs. Third, we apply our framework to the 2015 Nepal earthqu…
