Abstract

In recent decades, social research on youth in Italy has explored a wide range of issues through different interpretative and methodological approaches. However, there are very few studies that seek to identify the keynote features of the juvenile condition. This article argues that collective identities and forms of identification among youth are shaped more and more frequently through the sharing of social practices, of the meanings connected to these practices, and of more comprehensive lifestyles. With reference to four main fields (sport, music, politics, religion) and focusing on youth cultures, it analyses the connections between behaviours, attitudes, values and representations of youth actively involved in each of these different fields. The aim is to identify transversal processes through which young people today elaborate and adopt social practices and cultural profiles, create new social forms, and develop innovative signification processes.  相似文献

The paper focuses on the resurgence of the regions as protagonists of the process of the state rescaling in many European countries. In the EU countries this process can be seen as a result of a mix of economic and institutional factors, which have been producing an increasing competition between the central governments and the regional authorities. The rise of the multi-level governance and of the so-called Euroregionalism has reinforced the role of the regional scale in the territorial development: on one hand, with new actors like agencies and organizations engaged in the economic development (FDI attraction, place marketing, innovation and learning), on the other hand by the resurgence of “old” actors, such as the regions, in many cases empowered by processes of institutional devolution. The literature has investigated this re-composition of the political space with regard to the “hollowing out” and the “rescaling” of the state. On the base of these theoretical underpinnings, we discuss some empirical evidence from the Italian experience, in order to show whether and how the regional structures are not only “spaces for policies”, but also “spaces for politics”. Over the last decade, the changes in legal framework, the external inputs from supranational levels of government—the European Commission—and the re-territorialization processes have introduced many elements of innovation in the role of the regions. By illustrating the case of the Piedmont Region, we try to demonstrate that the transition towards the region as an active space of politics can be mediated by the sphere of the policies, especially the spatial ones.  相似文献

The cargo of marble blocks off Capo Bianco was dated to the Roman period. New sampling and analysis has identified Carrara marble, and also Rosso di Francia and Portargento, which strongly suggests a post‐medieval date. This leads to the suggestion that nearby finds dating between the second half of the 18th century and the first half of the 19th may come from the same ship, perhaps sailing from France and Liguria to deliver stone in southern Italy. This is rare evidence of the post‐medieval marble trade and demonstrates the importance of archaeometric analysis for the interpretation of wrecked cargos. © 2011 The Authors  相似文献

An extensive experimental program was carried out at EUCENTRE, within a research project on the evaluation and reduction of the seismic vulnerability of stone masonry structures. The main part of the experimental program has been devoted to the shaking table tests on three full-scale, two-story, single-room prototype buildings made of undressed double-leaf stone masonry. The first building tested was representative of existing unreinforced stone masonry structures with flexible wooden diaphragms, without any specific anti-seismic design nor detailing. In the second and third buildings, strengthening interventions were simulated on structures theoretically identical to the first one, improving wall-to-floor and wall-to-roof connections and increasing diaphragm stiffness. In particular, in the third specimen, steel and r.c. ring beams were used to improve the diaphragm connection to the walls and collaborating r.c. slab and multi-layer plywood panels were used to stiffen floor and roof diaphragms, respectively. This article describes the strengthening interventions applied to the third building prototype and presents the experimental results obtained during the shaking table tests. The results obtained permitted the calibration of a macroelement model representative of the nonlinear behavior of the structure.  相似文献

Ground-Based Synthetic Aperture Radar Interferometry (GBInSAR) and Terrestrial Laser Scanning (TLS) were purposely integrated to obtain 3D interferometric radar point clouds to facilitate the spatial interpretation of displacements affecting archaeological monuments. The paper describes the procedure to implement this integrated approach in the real-world situations of surveillance of archaeological and built heritage. Targeted tests were carried out on the case study of the Domus Tiberiana sited along the northern side of the Palatino Hill in the central archaeological area of Rome, Italy, and displacements of the monument were monitored over almost one year of acquisition. The GBInSAR – TLS integration provided updated information about the condition of the archaeological structures in relation to their history of instability mechanisms, and did not highlighted a general worsening for the stability of the entire monument. Point-wise and prompt detection of displacement anomalies and/or sudden changes in displacement trends proved the suitability of the method to support early warning procedures, also to evaluate effects on the masonry due to human activities.  相似文献

Abstract. This paper provides an empirical investigation of the advantages accruing to workers in industrial clusters. Using a unique data set based on the Cluster Mapping Project of the Italian National Statistical Institute, we examine whether industry agglomeration leads to wage and labor mobility differentials. We estimate complete Mincerian wage equations, investigating whether returns to seniority and education are a possible source of differentiation. We find that working in an industrial cluster reduces the returns to education, does not affect the returns to seniority, and does not provide average wage premia. On the other hand, industrial agglomeration positively affects the likelihood of being employed, of starting a business, and of making a transition from payroll employment to entrepreneurship; it also increases blue‐collar worker mobility across jobs.  相似文献

Giuseppe Levi (1872-1965), Professor of Anatomy at the University of Turin, had broad research interests and was a pioneer of in vitro studies on cultured cells. He provided a number of contributions on the nervous system, especially on the plasticity of sensory ganglion cells. An influential and magnetic teacher and mentor, he gathered around him a large group of brilliant students. He has the peculiar primate to count among his students three Nobel laureates in Physiology or Medicine: Salvador Luria, Renato Dulbecco, and Rita Levi-Montalcini. For all three of them, the internship in Levi's laboratory provided an exceptional initial stimulus. They remained in close contact with each other and with Levi even after the 1940s when they migrated to the United States for political and racial reasons, engaging in different fields of research. Rita Levi-Montalcini, who was awarded the Nobel Prize (1986) for the discovery of Nerve Growth Factor, was stimulated and assisted in her work by Giuseppe Levi during the difficult years of World War II. With Giuseppe Levi, she pursued early studies on the relationships between neural centers and their peripheral target of innervation, and she has witnessed in her writings the enthusiasm of her mentor.  相似文献

Seven bronze bangles from Tell en-Nasbeh, northern Judah, were investigated to understand the phase composition and manufacturing process of the artifacts, and possibly suggest a provenance for their origin. Synchrotron x-ray radiation diffraction (XRD) and fluorescence (XRF) were used in the analysis to avoid any destructive sampling and at the same time penetrate through the surface into the core metal. These techniques enabled us to determine that the bangles were not just tin bronze, but leaded tin bronze. Based on excavation reports, it is unlikely that the metal objects were manufactured locally at Tell en-Nasbeh; rather, preliminary XRD and XRF data point towards the neighboring region of Edom as their origin. Despite their political enmity during the Iron Age II, the data suggest that Judahite social demands for bronze may have fostered a strong economic relationship between these two polities.  相似文献
