This article focuses on emerging forms of ethnic identification among Italians of Ethiopian and Eritrean origins. In 2013, in parallel with the so-called refugees’ crisis in Europe, children of ...immigrants engaged in the Milanese management of forced migrations in the diasporic neighbourhood of Milano Porta Venezia. They legitimated their actions by emphasising a shared Habesha ancestral ethnicity with the asylum seekers from the Horn of Africa. The article considers their ethnic identification in relation to the changes in the public discourse on the Mediterranean route. These ethnic identifications and mobilisations are interpreted as claims for social recognition as Italians rather than a form of the revivification of their ancestral ethnicity in the analysis. The Black Mediterranean represent a privileged analytical and physical space to work on the resignification of Afro-European subjectivities in contemporary Europe.
Active slow-moving landslides in clayey soils exhibit continuous movements generally controlled both in the accelerating and decelerating phases by the pore-water pressure regime that, in turn, is ...strictly correlated to the net rainfall regime. The paper stresses the importance of a reliable groundwater model to predict these types of movements. To this aim a procedure is proposed to define the transient groundwater regime in the slope on the basis of recorded rainfall and monitoring data; the model is then used to derive the time-dependent shear strength along the main slip surfaces. The displacements at selected points along the slip surface are computed using a phenomenological (i.e., empirical) relationship between the local factor of safety and the displacement rate at those points. The procedure is employed for the analysis of a well-documented case history: the Porta Cassia landslide (central Italy).

A framework is proposed to characterize and forecast the displacement trends of slow-moving landslides, defined as the reactivation stage of phenomena in rocks or fine-grained soils, with movements ...localized along one or several existing shear surfaces. The framework is developed based on a thorough analysis of the scientific literature and with reference to significant reported case studies for which a consistent dataset of continuous displacement measurements is available. Three distinct trends of movement are defined to characterize the kinematic behavior of the active stages of slow-moving landslides in a velocity-time plot： a linear trend-type I, which is appropriate for stationary phenomena; a convex shaped trend-type II, which is associated with rapid increases in pore water pressure due to rainfall, followed by a slow decrease in the groundwater level with time; and a concave shaped trend-type III, which denotes a non-stationary process related to the presence of new boundary conditions such as those associated with the development of a newly formed local slip surface that connects with the main existing slip surface. Within the proposed framework, a model is developed to forecast future displacements for active stages of trend-type II based on displacement measurements at the beginning of the stage. The proposed model is validated by application to two case studies.

Sunitinib is the most commonly prescribed drug for advanced renal cell carcinoma in the first-line setting and has been associated with multiple adverse events related to its on-and off-target ...effects, including hand and foot syndrome and fatigue. It was hypothesized that sunitinib-induced fatigue may be related to off target inhibition of the AMPK enzyme, which results in impairment of energy-producing processes at a systemic level. Quercetin is a naturally occurring flavonol with established AMPK-stimulating activity. While clinical use of quercetin is limited by its poor bio-availability, quercetin-3-O-β-d-glucopyranoside, that is isoquercetin, has an improved pharmacokinetic profile. On the grounds of the
stimulatory activity with respect to AMPk, we hypothesized that oral isoquercetin could improve fatigue in kidney cancer patients receiving sunitinib. Given the lack of data on the safety of isoquercetin given concomitantly with sunitinib, we conducted a phase I trial to assess the safety of GMP manufactured isoquercetin given at two dose levels (450 and 900 mg a day). In the 12-patient study cohort included in this study, isoquercetin was administered concomitantly with 50 mg sunitinib for a median 81 days (IQR, 75.5, 86.5). None of the 12 patients required isoquercetin suspension or isoquercetin dose reduction because of adverse events. No abnormalities in ECG, heart or lower limbs doppler ultrasound were detected. A statistically significant improvement was reported for the FACIT fatigue score (6.8 points; 95% CI: 2.8-10.8;
= 0.002) and for the FACIT Adverse Events score (18.9 points; 95% CI: 9.1-28.8;
< 0.001) after isoquercetin consumption vs. baseline. In this phase I trial, isoquercetin was remarkably safe, with a preliminary signal of activity in terms of improvement of sunitinib adverse events.
Abstract Nel Sud Europa agricolo sono ormai realtà consolidata i cosiddetti ghetti, spazi di vita della componente migrante più fragile proveniente dal Sud globale e impiegata come forza lavoro ...bracciantile. Tali spazi vengono sovente inquadrati come confini della modernità occidentale, buchi neri in cui operano caporali che riproducono quelle che vengono definite come nuove schiavitù. In questo lavoro, partendo da una ricerca-azione svolta nel Sud Italia agricolo (Eboli), si propone di abbandonare una logica del confine e guardare alle modalità attraverso cui il ghetto diventa parte integrante del contesto più ampio, dei suoi modelli sociali, giuridici, economici. Situando l’etnografia sulle modalità attraverso cui l’intermediazione informale naviga queste strutture, il ghetto emerge come una frontiera, intesa non come confine ma come un avamposto che mostra gli effetti più violenti dei campi di forza che agiscono sulla riproduzione della presenza migrante.
Abstract In agricultural Southern Europe, so-called ghettos are a consolidated phenomenon. In these spaces the most fragile migrants coming from the global South are employed as laborers. These spaces are often framed as the borders of Western modernity, where intermediators operate and reproduce what is defined as new slavery. In this work, drawing from a research-action carried out in agricultural Southern Italy (Eboli), I propose to abandon a logic of the border and look at the ways in which the ghetto becomes part of the larger context, of its social, legal, economic models. By ethnographically focusing on the ways in which informal intermediation navigates these structures, the ghetto emerges as a frontier: not a border but a frontline that shows the most violent effects of the structures that act on the reproduction of migrant presence.
In this paper I will focus on the rising of the “diaspora neighborhoods” in Mekele, the capital of Tigray region (Ethiopia). In particular, I will consider the diasporic commitment in the ...house-building process, disconnecting it from “homecoming” projects, and linking it to the reproduction of the diasporic affective networks. Drawing on an ethnography of an apparent failed return from the diaspora, I will anthropologically explore the unsettled dwelling practices constituting the diaspora houses fruition. I will specifically focus on the transnational regimes of mobility facilitating, impeding and orienting the housebuilding processes, as well as on the interconnection between the movers and those who stay behind in the housebuilding decision. Diaspora houses, in this perspective, will be analyzed as proper infrastructures of mobility, as nodal points of the familiar and affective networks sustaining the diaspora social life.
In this paper, we consider minimizers of integral functionals of the type F(u)≔∫Ω1p(|Du(x)|γ(x)−1)+pdx,for p>1, where u:Ω⊂Rn→RN, with N≥1, is a possibly vector-valued function. Here, |⋅|γ is the ...associated norm of a bounded, symmetric and coercive bilinear form on RnN. We prove that K(x,Du) is continuous in Ω, for any continuous function K:Ω×RnN→R vanishing on {(x,ξ)∈Ω×RnN:|ξ|γ(x)≤1}.
