Sicurezza e populismo. I migranti alla frontiera del diritto penale
2023
Il presente lavoro di ricerca ha ad oggetto la criminalizzazione delle migrazioni nell'èra del cosiddetto populismo, e in particolare del populismo penale. Invero, negli ultimi anni si è assistito ad una espansione incontrollata del potere punitivo che, sotto la pressione di un bisogno collettivo di sicurezza, ha condotto ad una vera e propria disumanizzazione del diritto penale (e punitivo-amministrativo), nel duplice significato che quest’ultima espressione rivestiva secondo la giurispoeta Mireille Delmas-Marty: "quello di un diritto penale che si sta deumanizzando, e quindi deumanizzato, in quanto sempre più distante dai principi dell'umanesimo giuridico; e quello di un diritto penale de…
Experimental FTIR-MI and Theoretical Studies of Isocyanic Acid Aggregates
2023
Homoaggregates of isocyanic acid (HNCO) were studied using FTIR spectroscopy combined with a low-temperature matrix isolation technique and quantum chemical calculations. Computationally, the structures of the HNCO dimers and trimers were optimized at the MP2, B3LYPD3 and B2PLYPD3 levels of theory employing the 6-311++G(3df,3pd) basis set. Topological analysis of the electron density (AIM) was used to identify the type of non-covalent interactions in the studied aggregates. Five stable minima were located on the potential energy surface for (HNCO)2, and nine were located on the potential energy surface for (HNCO)3. The most stable dimer (D1) involves a weak, almost linear N-H⋯N hydrog…
A Matrix Model For An Energy Management System Based On Multi-Carrier Energy Hub Approach
2015
The INGRID FP7 European co-funded project studies several methodologies concerning hydrogen production and storage, aiming to provide services to electricity system operators for suitably balancing electrical supply and demand. In such a context, the problem of integrating different carriers into a single multi-hub optimiser represents a challenging topic for the research. This paper depicts the Energy Management System (EMS) of the plant which will be developed and built as a prototype of the INGRID system. The approach followed for the EMS design and development takes the cue from the matrix model presented in the rest of the paper, as well as the general optimisation problem formulation …
Self-assembly of 2,8,14,20-tetraisobutyl-5,11,17,23-tetrahydroxyresorc[4]arene
1999
We report herein the observation of a hexameric structure of a hydroxyresorc[4]arene in the solid state, enclosing a large interior space. This artificial molecular container is stabilized only by hydrogen bonds. The tendency to form aggregates in solution is demonstrated mainly by means of ESI-MS methods.
How the unbanked cope with financial exclusion: Evidence from Pakistan
2016
This article investigates both the coping strategies employed by low-income unbanked consumers in Pakistan and the consequences of those strategies. Qualitative data were gathered from low-income unbanked consumers through in-depth interviews. The findings suggest that unbanked consumers utilize their respective social networks and various market and personal resources to cope with financial exclusion. The utilization of social network resources to cope with financial exclusion typically enabled participants to fulfill their obligations in a positive manner and enhanced solidarity and trust among group members, whereas the use of market and personal resources tended to produce more negative…

Reilu siirtymä, ekologinen solidaarisuus ja kestävyysmurroksen mahdollisuus?
2021
Ekologisen kriisin ratkaisemiseksi tarvittavan kestävyysmurroksen yhteydessä on lisääntyvästi alettu keskustella oikeudenmukaisuudesta tai reiluudesta. Reilu siirtymä tarkoittaa sosiaalisen oikeudenmukaisuuden nostamista keskeiseksi osaksi ympäristökriisin ratkaisua, mikä on tärkeää sekä siirtymän hyväksyttävyyden että toimivan toteutuksen kannalta. Samalla oikeudenmukaisuuden korostaminen pitää kuitenkin sisällään riskin ympäristökriisin ratkaisemisen hidastumisesta. Erityisesti näin voi käydä, mikäli oikeudenmukaisuus kääntyy tarkoittamaan oikeutta kestämättömien elämäntapojen ja yhteiskuntarakenteiden ylläpitämiseen. Tarkastelemme tässä katsauksessa reilua siirtymää kriittisesti ja nosta…
Définir et comprendre l’ESS sur les territoires frontaliers franco-suisses :l’observatoire ESSpace
2022
The four Franco-Swiss chambers of the Social and Solidarity Economy (SSE) (Franche-Comté, Vaud, Rhône-Alpes and Genève) collaborated from 2012 to 2014 in an Interreg IV project, the purpose of which was to conduct "a collective reflection to support the development, enhance the value of good practices and social and solidarity initiatives from one region to another" (Project Summary Document, 2015). This reflection aims to understand together how the SSE is experienced in these territories, to explore the similarities, nuances and differences.A corpus of the various definitions of the actors themselves, and selected by these actors, was constituted and analysed according to the method of Co…
Anomalous and normal Hall effect in hydrogenated amorphous Si prepared by plasma enhanced chemical vapor deposition
2010
The double sign anomaly of the Hall coefficient has been studied in p -doped and n -doped hydrogenated amorphous silicon grown by plasma enhanced chemical vapor deposition and annealed up to 500 °C. Dark conductivity as a function of temperature has been measured, pointing out a conduction mechanism mostly through the extended states. Anomalous Hall effect has been observed only in the as-deposited n -doped film, disappearing after annealing at 500 °C, while p -doped samples exhibit normal Hall effect. When Hall anomaly is present, a larger optical band gap and a greater Raman peak associated with Si-H bond are measured in comparison with the cases of normal Hall effect. The Hall anomaly wi…
Structural Changes of Titanium Oxide Induced by Chromium Addition as Determined by an X-Ray Diffraction Study
1995
Abstract An X-ray diffraction study has been carried out on a series of polycrystalline TiO 2 (anatase) catalysts containing Cr(III) at different atomic concentrations (0.2-5.0 at. %), prepared by a co-precipitation method. Analysis of the variation of the unit cell parameters of chromium-doped anatase with respect to pure anatase has allowed us to estimate the solubility limit for the system at around 1.4 at. %. There is no evidence for the existence of a separate crystalline chromium oxide phase. Temperature effects on the cell parameter and on the anatase-rutile transformation rate were also analyzed. An increase in temperature produced release of the chromium from the solid solution. At…
