Equity of Public Pension System
2020
Fairness is an important feature of pension systems, but it is a wide concept with multiple sides. In this chapter, we try to distinguish some of them with the aim of using the terms in a proper manner. More specifically, we have observed at least five meanings for the notion of fairness when applying to a pension system: justice, equity, neutrality, solidarity and integrity. We explain each sense of fairness and other related concepts. We also provide, when possible, a way to measure each of them, with some figures for a selected European countries.
La pensée métaphysique de Heidegger. La transcendance du Dasein comme source d'une metaphysica naturalis
2006
La publication relativement récente des manuscrits de Heidegger dans l"Édition complète (éditée depuis 1975) a permis la découverte des chemins qu"a empruntés cette pensée jusqu"à son « apparition publique » en 1927. Mais en plus de dévoiler tout un pan du travail antérieur à 1927 « l"herméneutique de la facticité », principalement, la parution de ces cours a permis d"éclairer une partie assez méconnue du travail effectué immédiatement après Sein und Zeit, soit l"élaboration d"une « métaphysique du Dasein ». Dès 1929, le texte Kant und das Problem der Metaphysik avait rendu visible mais dans une certaine mesure seulement les modifications que subissait alors la pensée heideggérienne. Ce n"e…
Performance of a Focused Cavity Aerosol Spectrometer for Measurements in the Stratosphere of Particle Size in the 0.06–2.0-µm-Diameter Range
1995
A focused cavity aerosol spectrometer aboard a NASA ER-2 high-altitude aircraft provided high-resolution measurements of the size of the stratospheric particles in the 0.06-2.0-micrometer-diameter range in flights following the eruption of Mount Pinatubo in 1991. Effects of anisokinetic sampling and evaporation in the sampling system were accounted for by means adapted and specifically developed for this instrument. Calibrations with monodisperse aerosol particles provided the instrument's response matrix, which upon inversion during data reduction yielded the particle size distributions. The resultant dataset is internally consistent and generally shows agreement to within a factor of 2 wi…
Time Of Flight measurements via two LiDAR systems with SiPM and APD
2016
In this paper, we present an experimental comparison of two LiDAR systems, employing the SiPM and the APD as photodetectors, in terms of TOF measurements differing for the distance of the target and at different intensities of ambient light. The use of the APD represents the conventional approach, while the implementation of the SiPM is innovative. The performed measurements achieved very promising results, thus demonstrating the effectiveness of our LiDAR based on SiPM.
ARCADE: Description of the project and setup of the Lidar/AMT system
2015
The ARCADE (Atmospheric Research for Climate and Astroparticle DEtection) project is a 3 years project funded by MIUR, that aims to study the aerosol attenuation of UV light in atmosphere using multiple instruments and techniques, as those commonly used in the cosmic rays community: elastic Lidar, Raman Lidar, side-scattering measurements using a distant laser source. All measurements will be acquired on the same air mass at the same time, in a semi-desertic site near Lamar, Colorado (U.S.). For each instrument, multiple analysis techniques will be tested: the target is a better comprehension of the systematics and limits of applicability of each method. The system is composed by a Lidar (e…
“Podalirius” o “Polidarius”? Da Arrigo da Settimello a Guido delle Colonne
2016
This paper is dedicated to the defence of the variant "Polidarius" (and not the correction in the vulgate "Podalirius") that occurs in all the manuscripts of Henry of Septimello's «Elegia» (book IV, line 209). "Polidarius", however, has many attestations in Medieval Troy literary tradition (Joseph of Exeter, Benoît de Sainte-Maure, Guido delle Colonne) and is an alternative, correct and good name for the famous mythical doctor, son of Asclepius and brother of Machaon.

In this article we explore the effects that new information and communication technologies (ICTs) have on family relations in Finland. The idea of ‘new connectivities’ works as a starting point for...
‘I think I will need help’: A systematic review of who facilitates the recovery from gender‐based violence and how they do so
2020
Context A key to advancing the eradication of gender-based violence (GBV) is knowing how to recover from it. Objective To identify the changes that are indicators of having overcome GBV and determine the role of various support networks. Search strategy We systematically searched Web of Science. Inclusion criteria Publications whose abstracts contained a minimum of two of the following words: (a) support or network or solidarity, (b) violence and (c) recovery or healing. Data extraction and synthesis Of the 273 documents retrieved, 52 were used using a narrative synthesis approach. Main results For recovery, women must reconnect with themselves, with their environment and with the world in …
Conclusion and Discussion
2021
It would seem that European Politics are currently enrolled in a constant flux of uncertainty and anxiousness. The Institutional Matrix and Community of states that make up the Union seemingly cannot catch a break as they meander through a succession of crises and challenges. These are taking their toll on the EU, its unity in decision making, and countries’ commitment to ever closer Union. The sovereign debt crisis and so-called Greek Euro Crisis shook the tacit belief in the current economic architecture of the bloc and questioned the belief in intra-European solidarity. Shortly thereafter, the refugee crisis saw European States adopt ad hoc and sometimes contradictory measures for border…
Measuring Social Solidarity. Some Research Notes
2012
Abstract There is an increasing public, political and research interest in social solidarity. Even though the concept has a long history and is embedded in solid approaches, there is not much literature concerned with its measurement. The paper falls into the area of the methodological studies of social solidarity and it deals with construct validation. The objective of this paper is to test for convergent validity and nomological validity of two sets of items aiming to measure social solidarity attitudes and acts. The main method employed is confirmatory factor analysis.
