ABSTRACTThis paper explores, from an ethnographic standpoint, the mobility of a Bosnian Romani community in relation to the xenophobic and anti-Romani discourses that are pervading contemporary Italian and European society in the time of the so-called migrant crisis. The analysis focuses on some so-called Xomá families who live dispersed among illegal shanties in the Rome and whose movements and social network protract into other Italian and European cities. The question of mobility is addressed both in terms of local movements within the Roman peripheries and of wider transnational trajectories. Romani mobility appears as a tactical response to processes imposed from above that challenges the forms of governmentality related to the policing of borders and the production of boundaries of the EU and its member-states. 相似文献

ABSTRACTBorders are back with a vengeance. From the Americas to the Mediterranean, borders cut through the increasingly integrated world in a way that exposes the inside-outside logic of contemporary capitalism. All this happens on a backdrop where cities are becoming the key sites of contestation since borders and levees do not suffice to keep them intact. Cities are also increasingly becoming the focus of international efforts to deal with climate change and migration, where nation-states are falling short. By synthesizing the possibilities of urban belonging and right-to-the-world, we argue that new urban imaginaries are at the frontline of the mobilities debate today. Consequently, we argue for a cross-pollination of mobility justice and climate justice as urban citizenship. The main thrust of our argument is that there are viable alternatives to the isolationist fortress nation model, which can bring a new dimension to debates concerning climate change and migration. Fearless cities are but one example of these emerging alternatives. By focusing on the opportunities for a radical response to climate change and migration, we suggest that cities can respond to the burning mobility challenges of our times with a just, grounded and egalitarian urban citizenship framed as mobile commons. 相似文献

Here we present as case study how re-randomization tests were performed in two randomized, controlled clinical trials as sensitivity analyses, as recommended by the United States Food and Drug Administration in the context of adaptive randomization. This was done to confirm primary conclusions on immunological noninferiority of an investigational new fully liquid presentation of a quadrivalent cross-reacting material conjugate meningococcal vaccine (MenACWY-CRM), over its licensed lyophilized/liquid presentation. In two phase 2b studies (Study #1: NCT03652610; Study #2: NCT03433482), noninferiority of the fully liquid presentation of MenACWY-CRM to the licensed presentation was assessed and demonstrated for immune responses against meningococcal serogroup A (MenA), the only vaccine component modified from lyophilized to liquid in the new presentation. The original vaccine assignment algorithm, with a minimization procedure accounting for center or center within age strata, was used to re-randomize participants belonging to the fully liquid and licensed vaccine groups while keeping antibody responses, covariates and entry order as observed. Test statistics under re-randomization were generated according to the ANCOVA model used in the primary analysis. To confirm immunological noninferiority following re-randomization, the corresponding p-values had to be <0.025. For both studies and all primary objective evaluations, the re-randomization p-values were well below 0.025 (0.0004 for Study #1; 0.0001 for the two co-primary endpoints in Study #2). Re-randomization tests performed to comply with a regulatory request confirmed the primary conclusions of immunological noninferiority for the MenA of the fully liquid compared to the licensed vaccine presentation. 相似文献

Abstract. This paper presents an original data set of microdata on the tax wedge in Italy, obtained by using the microsimulation model ITAXMOD, developed at ISPE (Institute for Studies on Economic Planning). These data are used to measure the components of the tax wedge and their burden on the total cost of labour at the individual level. The results have been aggregated across income brackets, socio-economic groups and sectors of employment. These data are the necessary preliminary input for any redistributive analysis and in addition they make the available data for Italy comparable with those of other countries. Scant attention has been paid up to now to the redistributive aspects of the tax wedge, since most analyses are based on the income of the “average production worker” which is far from an ideal standard for comparison. The computation of the tax wedge for different brackets of total labour cost has been explored in two ways. The first is related to the differing weights of the components of the tax wedge on cost of labour and no particular hypothesis has been made about the incidence of these components. The results show that the burden of personal income taxation and of social security contributions is very high even for wage-earners in the lowest brackets (in 1992, the estimated tax wedge is more than 44% of total labour cost even in the second decile of the labour cost). That might discourage both labour supply and labour demand across the entire spectrum of deciles of cost of labour. The second line of research studies the incidence of personal income taxes and employees' social security contributions on gross earnings, under the maintained hypothesis that these two components of the tax wedge are shouldered by the employees. 相似文献
