Migrant Families, Social Policies and Community Relations: Towards What (Kind Of) Integration?
2022
This article aims to present a few considerations regarding the phenomenon of migrant families’ integration processes, in the broader framework of the relationship between politics, policies and services. The stabilization of migrant people in Italy has determined, on the one hand, the growth of the family-based character of the immigrant population, in the face of which, institutions and reception services, in the wake of policy directives, have been called upon to remodel interventions and integration practices. On the other hand, the drastic reduction in political attention to the social, civil and economic integration of migrants and, in particular, of migrant families, linked to the di…
SEPARATED CHILDREN. Minori, identità e pratiche dell'appartenenza
2016
Il volume raccoglie le ricerche, lavori scientifici e di campo, altamente qualitativi, che si soffermano altresì sull’impatto che le vicissitudini e le trame familiari storiche e singolari, appartenenti ad altri mondi e ad altre logiche di senso, agiscono sulle configurazioni identitarie di queste esistenze in movimento/mutamento nel contesto dei fattori di spinta delle mobilità umane attuali (guerre, povertà, disastri ambientali e cambiamenti climatici). I saggi, sia in italiano sia in inglese, colgono, da una prospettiva delle scienze sociali, umane, economiche e giuridiche, sui concetti di transiti e di soste nei non–luoghi istituzionali (i vari centri di accoglienza di primo e/o di seco…
Contribution to the analysis of signals obtained by dynamic photon emission for the purpose of studying very large scale integration circuits
2014
Scaling progresses has the benefit of making chips always more powerful. On the other hand, when there is a failure, the analysis of such advanced devices has became more sensitive. The defect localization step of this process is the critical one. Indeed, the aim is to find transistors which dimensions range in several nanometers on a device which surface is several square centimeters.Optical techniques like dynamical photon emission, also named Time Resolved Imaging (TRI), have proved to fit in such context. The later is based on the acquisition and exploitation of photons emitted by a switching CMOS structure. Due to its physical bacground, this tool has a limited invasive effect and can …
Oral and Vaginal Epithelial Cell Lines Bind and Transfer Cell-Free Infectious HIV-1 to Permissive Cells but Are Not Productively Infected
2014
The majority of HIV-1 infections worldwide are acquired via mucosal surfaces. However, unlike the vaginal mucosa, the issue of whether the oral mucosa can act as a portal of entry for HIV-1 infection remains controversial. To address potential differences with regard to the fate of HIV-1 after exposure to oral and vaginal epithelium, we utilized two epithelial cell lines representative of buccal (TR146) and pharyngeal (FaDu) sites of the oral cavity and compared them with a cell line derived from vaginal epithelium (A431) in order to determine (i) HIV-1 receptor gene and protein expression, (ii) whether HIV-1 genome integration into epithelial cells occurs, (iii) whether productive viral in…
Benedetto XVI e il compito urgente dell’educazione
2015
All’origine della riflessione sull’urgenza di una Nuova Evangelizzazione ci sta la constatazione di una diffusa situazione di crisi di valori cristiani e educativi, percepibili soprattutto nei Paesi di antica cristianità. Più volte, nei suoi discorsi, Benedetto XVI concentra l’attenzione sulla necessità di educazione: in primo luogo dei genitori «preoccupati e spesso angosciati per il futuro dei loro figli» degli insegnanti «che vivono la triste esperienza del degrado delle scuole» e della società stessa «che vede messe in dubbio dalla crisi dell’educazione le basi stesse della convivenza». Si evidenzia la necessità dell’educazione principalmente per le nuove generazioni. Ma la percezione d…
Interest Rate Convergence, External Balances and the Euro Crisis
2016
Typically, the catching-up process between rich Northern Europe and poor Southern Europe and the diverging cost competitiveness between the two regions are considered alternative explanations for the widening current account imbalances in the euro area. This paper proposes a new explanation for the imbalances which led to the 2009 euro crisis i.e. large interest rate differentials among the EMU-12 countries which prevailed before the adoption of the euro. This finding suggests that the euro crisis was, at least to some extent, a consequence of the initial convergence shock.
Shock formation in the dispersionless Kadomtsev-Petviashvili equation
2016
The dispersionless Kadomtsev-Petviashvili (dKP) equation $(u_t+uu_x)_x=u_{yy}$ is one of the simplest nonlinear wave equations describing two-dimensional shocks. To solve the dKP equation we use a coordinate transformation inspired by the method of characteristics for the one-dimensional Hopf equation $u_t+uu_x=0$. We show numerically that the solutions to the transformed equation do not develop shocks. This permits us to extend the dKP solution as the graph of a multivalued function beyond the critical time when the gradients blow up. This overturned solution is multivalued in a lip shape region in the $(x,y)$ plane, where the solution of the dKP equation exists in a weak sense only, and a…
Numerical study of the Kadomtsev–Petviashvili equation and dispersive shock waves
2018
A detailed numerical study of the long time behaviour of dispersive shock waves in solutions to the Kadomtsev-Petviashvili (KP) I equation is presented. It is shown that modulated lump solutions emerge from the dispersive shock waves. For the description of dispersive shock waves, Whitham modulation equations for KP are obtained. It is shown that the modulation equations near the soliton line are hyperbolic for the KPII equation while they are elliptic for the KPI equation leading to a focusing effect and the formation of lumps. Such a behaviour is similar to the appearance of breathers for the focusing nonlinear Schrodinger equation in the semiclassical limit.
