    This essay offers an evaluation of the present dimensions of childhood, where can be found new hints and elements from the quoted classics not yet fully developed. "Re-writing" childhoodin the society of human rights is an ethical and cultural duty, as well as an engagement requiring equal, inclusive, and high quality education. Such an opinion is clearly traceable to recent Europeandocuments and in the Sustainable Development Goals.Il contributo propone una riflessione sull’attuale dimensione dell’infanzia, nella quale sono presenti nuovi spunti ed elementi dei Classici non ancora realizzati. “Ri-scrivere” l’infanzia nella società dei diritti umani è un dovere etico e culturale, nonché un impegno a cui rispondere con un’educazione di qualità, equa ed inclusiva. Questa convinzione emerge con chiarezza nelle recenti documentazioni europee e nell’ “Agenda Globale per lo sviluppo sostenibile (SDGs)”

    Hubble Space Telescope Combined Strong and Weak Lensing Analysis of the CLASH Sample: Mass and Magnification Models and Systematic Uncertainties

    We present results from a comprehensive lensing analysis in HST data, of the complete CLASH cluster sample. We identify new multiple-images previously undiscovered allowing improved or first constraints on the cluster inner mass distributions and profiles. We combine these strong-lensing constraints with weak-lensing shape measurements within the HST FOV to jointly constrain the mass distributions. The analysis is performed in two different common parameterizations (one adopts light-traces-mass for both galaxies and dark matter while the other adopts an analytical, elliptical NFW form for the dark matter), to provide a better assessment of the underlying systematics - which is most important for deep, cluster-lensing surveys, especially when studying magnified high-redshift objects. We find that the typical (median), relative systematic differences throughout the central FOV are 40%\sim40\% in the (dimensionless) mass density, κ\kappa, and 20%\sim20\% in the magnification, μ\mu. We show maps of these differences for each cluster, as well as the mass distributions, critical curves, and 2D integrated mass profiles. For the Einstein radii (zs=2z_{s}=2) we find that all typically agree within 10%10\% between the two models, and Einstein masses agree, typically, within 15%\sim15\%. At larger radii, the total projected, 2D integrated mass profiles of the two models, within r\sim2\arcmin, differ by 30%\sim30\%. Stacking the surface-density profiles of the sample from the two methods together, we obtain an average slope of dlog(Σ)/dlog(r)0.64±0.1d\log (\Sigma)/d\log(r)\sim-0.64\pm0.1, in the radial range [5,350] kpc. Lastly, we also characterize the behavior of the average magnification, surface density, and shear differences between the two models, as a function of both the radius from the center, and the best-fit values of these quantities.Comment: 35 pages (20 main text pages, plus 15 pages for additional figures and tables); 2 Tables, 17 Figures. V3: accepted version; some minor corrections and additions made. V4: corrected several entries in Table 2. All mass models and magnification maps are made publicly available for the communit

    Contribution to the floristic knowledge of eastern Irpinia and Vulture-Melfese area (Campania and Basilicata, southern Italy)

    In order to improve the floristic knowledge of the Italian territory, we report the inventory of the taxa collected during the annual field trip of the working group for Floristics, Systematics and Evolution of the Italian Botanical Society held in 2015 in eastern Irpinia and Vulture-Melfese area (South Italy). The investigated territories are located in southern Apennines, along the border between the Campania and Basilicata administrative regions. These areas are scarcely known in terms of vascular flora. The floristic samplings were performed in 19 sites selected as representative of the local environmental diversity as regards to climate, litho-morphology and land-use. The research led to the identification of 4,137 specimens of vascular plants, belonging to 815 species and subspecies, 399 genera, and 85 families. Among these taxa, 42 were endemic to Italy, 38 were included in the IUCN Red List of the Italian Flora, 28 were alien and 5 were cryptogenic in Campania and/ or Basilicata administrative regions. Two taxa, Aquilegia coerulea (casual alien, native to North America) and Lolium ×boucheanum (native), were found to be new for Italy. On the basis of the available floristic literature the first one is also to be considered new for the European flora. At regional scale, we have found 18 taxa new for the Campania and 15 new for the Basilicata region. Finally, 10 taxa were confirmed for Campania. Data obtained during this study, confirmed the important role of a collaborative approach among botanists and the great relevance of these territories for plant diversity

    Search for new particles in events with one lepton and missing transverse momentum in pp collisions at √s = 8 TeV with the ATLAS detector

    Get PDF
    This paper presents a search for new particles in events with one lepton (electron or muon) and missing transverse momentum using 20.3 fb−¹ of proton-proton collision data at √s=8 TeV recorded by the ATLAS experiment at the Large Hadron Collider. No significant excess beyond Standard Model expectations is observed. A W′ with Sequential Standard Model couplings is excluded at the 95% confidence level for masses up to 3.24 TeV. Excited chiral bosons (W*) with equivalent coupling strengths are excluded for masses up to 3.21 TeV. In the framework of an effective field theory limits are also set on the dark matter-nucleon scattering cross-section as well as the mass scale M* of the unknown mediating interaction for dark matter pair production in association with a leptonically decaying W

    Educazione e Diritti Umani. Il manifesto di Freire

    Get PDF
    ItAlfabetizzazione e coscientizzazione sono i tratti di un'educazione volta al riscatto della dignità umana che diviene impegno concreto nelle esperienze e nella vita di Paulo Freire. Partendo da un'analisi socio-culturale, per poi approdare ad una "posizione epistemologica" dell'uomo, il saggio evidenzia il contributo del pedagogista che ha fatto della sua battaglia per l'alfabetizzazione la bandiera dei diritti umani. Se è vero che non basta rivendicare e proclamare tali diritti, occorre creare le "condizioni culturali" affinché questi possano concretizzarsi nella vita delle persone. L'educazione, che nella prospettiva freiriana è alfabetizzazione, esercizio di coscienza e pratica di libertà, rappresenta la risposta a quei bisogni personali che trovano espressione nel linguaggio e la loro ragione d'essere nella lettura della realtà. Sono questi gli obiettivi che ispirano Freire, convinto che l'educazione potrà formare "uomini nuovi", portatori a loro volta di messaggi ricchi di speranza, fiducia e fede, necessari per costruire un mondo più giusto ed equo, premessa ad un futuro migliore per l'intera umanità.EnLiteracy and comprehension are the distinctive features of the education process that approaches the human dignity issue as a concrete experiential commitment in the life of Paulo Freire. This research emphasizes how a socio-cultural analysis has led to the "epistemological positions" in the work of this pedagogist who has made of literacy the fight for human rights. It is therefore necessary to create the "cultural conditions" so that the psychological development of the person can actually be realized. In the perspective of this author, literacy is education, exercise of conscience and practice of freedom that represents and finds its own expression in language as the comprehension of the reality. These are the goals that Freire promotes, convinced that education can form "new men" - carriers of messages of hope, trust and faith in order to build a fairer world, a better future for the whole humanity

    The Ebla GIS: An Example of Reverse Archaeology

    No full text
    In the year 2017 the authors of the present paper developed a relational DataBase and an integrated GIS platform using as a case study the Ancient Bronze Age III-IVA1 archaeological contexts and materials ex- cavated by the MAIS Expedition (Italian Archaeological Mission to Syria) at Tell Mardikh/Ebla. The name of the project is ‘Ebla 2.0’. The DBRS has been organised to mirror the excavation system adopted since the 1960s by the MAIS Ex- pedition at Ebla (co-led by P. Matthiae and F. Pinnock). The paper will present the Ebla GIS as a case study of Reverse Archaeology. The aim is to discuss the solutions adopted by the authors to archive, manipulate and combine multiple datasets, providing a spatial dimension to the documentation preserved in the Ebla archives, and finally develop a useful tool to stimulate future research and applications

    The project of the Italian Archaeological Expedition in the Kurdistan Region of Iraq (MAIPE) of the University of Milan focuses on a small part of the Erbil plain, namely the area of Helawa/Aliawa, 27 km south-west of Erbil. In 2013 and 2015, a topographic survey with differential GPS was carried out at Helawa. The ensuing GIS-based spatial analysis of diagnostic materials made it possible to reconstruct the site’s main occupational phases and estimating its extension at different times in its history. In this paper, we will focus on additional aspects that emerged from our spatial analysis. The distribution of selected categories of finds (e.g., furnace wasters, lithic artefacts) throughout the site points to possible functional distinctions. Furthermore, our analysis of morphological data bears witness to processes of multilayer deposition and erosion, which contributed to shaping the site’s mound morphology through time
