Effectiveness of an executive function training in italian preschool educational services and far transfer effects to pre-academic skills
No full textIn this study we examine the effectiveness and far transfer effects of a training that was found to be effective in promoting Executive Function (EF) in a sample of 5-year-old children (Traverso et al., 2015). By contrast with Traverso et al. (2015), the intervention was administered by regular teachers to verify its ecological validity. Far transfer was assessed by evaluating the training effects on pre-academic skills. 126 children attending the last year of Italian preschool educational services took part in the study (mainly 5-year-old children). Pre-and post-test assessments were conducted using a large EF and pre-academic skill task battery. The results indicate that the experimental group outperformed the control group in an interference suppression composite score. Moreover, significant far transfer effects to pre-academic skills in literacy domain were found. In addition, we found that the improvement in the pre academic skills (in both literacy and math domains) was mediated by the improvement in the interference suppression score. The results suggest the possibility that this intervention, which may be easily implemented in the context of educational services, can promote EF during the preschool period before entry to primary school
Adriano Buzzati-Traverso
No full textAd ria no Buzzati- Traverso è stato uno dei principali esponenti della prima generazione di genetisti e biologi molecolari in Italia. A lui si devono molti sforzi, dopo la Seconda guerra mondiale, per l’ innovazione dell’organizzazione della ricerca nel Paese e per la diffusione della cultura scientifica. Fautore del necessario processo di internazionalizzazione della ricerca, anche a livello europeo è stato uno dei pri ncipali promotori della cooperazione continentale, contribuendo attivamente alla fond azione di alcune delle is tit uzioni sovranazionali nel campo delle scienze della vita . La sua figura è stata quindi fondamentale per la modernizzazione della cultura italian
Role of the edges in a quasicrystalline Haldane model
No full textWe study the role of the edges in determining the features of the topological phase in a quasicrystalline higher-order topological insulator. We consider a specific model consisting of two stacked Haldane models with opposite Chern number and a 30 degrees twist, whose structure is crystallographically equivalent to that of the graphene quasicrystal. We find that the gap-opening in the low-energy spectrum of the higher-order topological insulator occurs at different energies when different kinds of edges are considered. Crucially, bearded bonds appear to be necessary for the gap to appear close to the charge neutrality point. In the more realistic case of zigzag edges, the gap opens symmetrically in the electron and hole sectors, away from zero energy. We explain our findings by inspecting the edge bands of the decoupled bilayer, in the approximation of quasiperiodicity
Effects of the Vertices on the Topological Bound States in a Quasicrystalline Topological Insulator
No full textThe experimental realization of twisted bilayer graphene strongly pushed the inspection of bilayer systems. In this context, it was recently shown that a two layer Haldane model with a thirty degree rotation angle between the layers represents a higher order topological insulator, with zero-dimensional states isolated in energy and localized at the physical vertices of the nanostructure. We show, within a numerical tight binding approach, that the energy of the zero dimensional states strongly depends on the geometrical structure of the vertices. In the most extreme cases, once a specific band gap is considered, these bound states can even disappear just by changing the vertex structure
Environmental performance of building materials: life cycle assessment of a typical Sicilian marble
No full textBackground, aim, and scope: The building sector is strategically important for achieving sustainability. Therefore, the improvement of energy and environmental performances are relevant targets because precious building materials such as marble have a significant impact on the environment. The aim of this paper is an analysis of a typical Sicilian marble (Perlato di Sicilia) to evaluate its energy and environmental performance. Marble plays an important role in the economy of Italy and has a global market share of 58% in terms of exports. For the main production areas of marble, relevant environmental performance data are missing except for one region (Tuscany-Massa e Carrara province). Perlato di Sicilia, the main marble of Custonaci (Sicily), has never been analyzed previously. Materials and methods: Life cycle assessment (LCA) according to ISO 14040/44 is applied to marble tiles and slabs. For the life cycle inventory, data were collected from a representative plant in the Custonaci basin. In this small area of 69 km 2, about 54 quarries and related cutting plants are concentrated. The impact assessment includes the following categories: global warming potential (GWP), acidification potential (AP), eutrophication potential (EP), and photochemical oxidation (POCP), following the CML-IA baseline 2007. Results: The results of the impact assessment for 1 m3 of marble tiles are 314.8 kg CO 2eq of GWP, 1.19 kg SO 2eq of AP, 0.073 g PO 4 - -eq of EP, and 0.046 kg ethylene eq of POCP. For slabs, the corresponding results were 200.1 kg CO 2eq of GWP, 0.77 kg SO 2eq of AP, 0.053 kg PO 4 - -eq of EP, and 0.029 kg ethylene eq of POCP. The total embodied energy values of tiles and slabs are, respectively, 1,772 MJ/m 3 and 1,168 MJ/m 3. This comparison shows that tiles manufacturing has higher values of embodied energy and environmental performance indicators. The value of the Custonaci slabs is reasonable compared to the Carrara marble (mainly slabs), and the embodied energy value of which is between 698 MJ/m 3 and 1,414 MJ/m 3. The main contribution to the energy consumption is due to electricity demand: 80% for tiles and 75% for slabs. Moreover, a comparison with the European type I Ecolabel criteria for natural hard floor coverings has been carried out to understand the range of the environmental impacts of Perlato di Sicilia compared to the thresholds reported in European Decision 272/2002. Conclusions, recommendations, and perspectives: This study is the first LCA of a typical Sicilian marble. The environmental interventions of the Custonaci marble appear to be slightly higher than Carrara marble. The nature of Custonaci marble and the technology involved in its production have reached the same performance level as in Carrara. Nevertheless, Custonaci marble is on the way to being an environmentally friendly product, as is shown by the comparison with Ecolabel criteria. The hot spots determined in this study are: the amount of spoils produced during the extraction step, the disposal of sludge resulting from cutting and finishing directly in the sawmill, the lack of the water recycling treatment in the quarry itself (as outlined in the European Ecolabel criteria), and the high electricity consumption. © 2009 Springer-Verlag
Nuevas derechas, viejas izquierdas : Una conversación con Enzo Traverso
No full textThe present reflections are the result of a series of conversations with Enzo Traverso that took place in mid-November, in the city of Buenos Aires. Traverso obtained his PhD degree at the École des Hautes Études en Sciences Sociales (Paris, France), who currently works as a professor and researcher in the United States. Author of important books on contemporary European history, Enzo Traverso has written numerous reflections on historiographical practice and on the relationship between memory, politics and history. During his last visit to Argentina, he gave lectures and seminars in the framework of the Marx 200 years International Encounter. On this occasion, and about the publication in Spanish of his last two books (The New Faces of the Right and Left Melancholy. Marxism, history and memory), he agreed to discuss the new Latin American rights, the feminist movements, the situation of the left worldwide, and the nature of neoliberalism. Here we present and transcribe the result of those conversations.Las presentes reflexiones son el resultado de una serie de conversaciones con Enzo Traverso que tuvieron lugar a mediados de noviembre, en la ciudad de Buenos Aires.
