Il progetto Mobilità Sociale e Merito della Scuola Superiore Sant'Anna: gli obiettivi, la struttura e le metodologie adottate
I risultati di un modello sperimentale di orientamento: il progetto Mobilità Sociale e Merito
Obiettivo mobilità sociale. Sostenere il merito per creare valore nel sistema Paese
È possibile ridurre i condizionamenti socio-culturali e garantire che studenti di talento provenienti da contesti fragili godano delle stesse opportunità formative dei loro coetanei? Come è possibile perseguire efficacemente questo obiettivo? In risposta a queste domande, il volume presenta i risultati di un progetto di ricerca-azione del MIUR e della Scuola Superiore Sant’Anna di Pisa, in cui è stato sperimentato un modello di orientamento rivolto a studenti capaci e meritevoli, ma provenienti da contesti socio-culturali che ne ostacolavano l’accesso agli studi universitari. Il progetto ha visto il coinvolgimento di 290 studenti di licei e istituti tecnici e professionali, provenienti da famiglie con bassa scolarizzazione. «Tutorati» da allievi della Scuola Superiore Sant’Anna di Pisa in un percorso di coaching «peer to peer», mediante visite in loco e contatti web dalla terza classe fino alla maturità e alla scelta universitaria, questi studenti hanno conseguito risultati scolastici eccellenti e nel 90% dei casi hanno scelto di iscriversi all’università. Sulla base di quest’esperienza e di numerosi casi di studio internazionali, il volume offre possibili linee guida per la diffusione di una strategia per la promozione della mobilità sociale e la valorizzazione del talento, delineando un percorso che coinvolge tutti gli attori del sistema Paese – istituzioni pubbliche, mondo imprenditoriale e scuole – e che considera la diversità di background un’opportunità da valorizzare
Seismic upgrading of r.c. frame structures using a displacement based design procedure performed with OpenSees
A displacement-based procedure [1] to design dissipative bracing for the seismic protection of frame structures has been developed and some application developed with OpenSees are discussed. The procedure does not require sophisticated dynamic nonlinear analyses but only common non linear static analyses and is based on the displacement based design. Two performance objective have been considered developing the procedure: protect the structure against structural damage or collapse and avoid non-structural damage limiting global displacements and interstorey drifts. The procedure has been tested on case studies of r.c. frame building, considered both bare and infilled, modelled with OpenSees [2]. Infills have been represented by means of single strut elements with a constitutive model calibrated on experimental base [3]: experimental tests have been performed on r.c. portal samples, bare and infilled. The tests have been prepared using OpenSees numerical simulations and, finally, those models have been calibrated in order to obtain reliable numerical models
A imagem de Alessandro Baricco no Brasil
Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Estudos da Tradução, Florianópolis, 2013.Com a intenção de delinear o modo pelo qual o escritor italiano Alessandro Baricco se inseriu no sistema literário brasileiro e os caminhos percorridos pelos seus livros traduzidos, esta dissertação dá voz às experiências tradutórias de seus tradutores. A inserção de Bariccono Brasil tem seu início em 1997, através de uma proposição da Profa. Dra. Roberta Barni à editora Iluminuras da tradução de Oceano Mare. A partir daí, outras sete obras foram publicadas no Brasil, sendo três delas traduzidas por Roberta Barni e as outras quatro por quatro tradutores diferentes. De um lado, considera-se o tradutor como figura principal namediação entre culturas, e, de outro, se analisa a realidade desta figuradentro do sistema literário, sua invisibilidade, seus limites e o exercíciode sua profissão. A pesquisa conta, ainda, com críticas e resenhas referentes ao autor italiano publicadas em jornais consagrados no Brasil, considerando estas como parte constituinte da imagem de Baricco refletida em território nacional. Abstract : Intending to delineate the way the Italian writer Alessandro Baricco has been inserted in the Brazilian literary system and the paths his translated books have followed, this thesis gives voice to the translating experiences of his translators. Baricco's insertion in Brazil began in 1997, through a personal project of Dr. Roberta Barni, with her translation of Oceano Mare. Since then, seven other of his works have been published in Brazil, three of which were translated by Roberta Barni and the other four by four different translators. On the one hand,the translator is considered as the main figure in mediation betweencultures and, on the other, this figure's reality is analyzed within theliterary system: its invisibility, its limits and its professional practice. Criticisms and reviews of this Italian author published in well established Brazilian newspapers are also considered, with the understanding that they are part of Baricco's image reflected here
A design procedure for the seismic protection of infilled frames by dissipative braces. In: Proceedings of
<p>Existing reinforced concrete frame buildings with non-ductile detailing suffered severe damage and caused loss of life during earthquakes. Different rehabilitation systems have been developed to upgrade the seismic performance of this kind of structures. The research discussed in this paper, carried out under the partial financial support of “convenzione Dipartimento di Protezione Civile- Consorzio RELUIS, signed 11/07/2005 (repertorio n. 540), research line 2, deals with the seismic protection of frame structures, in particular for the application presented buckling restrained steel braces (BRB) have been selected. A displacement-based procedure to design dissipative bracing for the seismic protection of frame structures is proposed and some applications are discussed. A two- fold performance objective is considered to protect the structure against the collapse and the non- structural damage by limiting global displacements and interstorey drifts. As an example, some r.c. frame buildings, designed according to the non-seismic Italian Code, have been analyzed also considering the infills and retrofitted with BRB via the proposed procedure. In order to assess the effectiveness of the proposed rehabilitation design procedure non linear static and dynamic time- history analyses have been performed. Concluding the necessity of performing dynamic analysis, instead of non linear static analysis, on structures with dissipative bracing systems has been discussed.</p></jats:p
Compression tests on masonry walls realized with a single or double masonry panel
In this paper, the results of the experimental tests, carried out at the Laboratory on Materials and Structures of the University of Roma Tre to characterize masonry panels behavior are shown and discussed. 36 single and 12 double panels have been considered: 12 single panels are made of 80x160x330 mm3 bricks with horizontal holes, 24 of 120x250x120 mm3 half-full bricks with vertical holes and two different mortars and 12 double panels coupling the two previous types of simple panels. The panels have been built with a level of accuracy similar to the one adopted in buildings therefore they are well done but not lacking some defects that unavoidably would be found in real constructive practice. Compression tests in horizontal, vertical and diagonal directions were performed to evaluate their “constitutive relationships” in term of force-displacement diagrams and in particular their strength and elastic modulus.
Experimental tests also included the characterization of the bricks and of the mortar used to realize the panels
A design procedure for seismic retrofitting of reinforced concrete frame and concentric braced steel buildings with dissipative bracings
The research presented in this paper deals with the seismic retrofitting of existing frame structures by means of passive energy dissipation. An iterative displacement based pro cedure, based on capacity spectrum is described and some applications are discussed. The general procedure has also been discussed referring to the case of existing steel concentric braced frame structures (CBF). The procedure can be used with any typology of dissipative device and for different performance targets. In this work the procedure has been applied, with both traditional pushover (load profile proportional to first mode) and multimodal pushover, to an existing r.c. frame building. In the application presented the buckling restrained braces have been used in order to prevent damages to both the structure and non structural elements. The use of multimodal pushover proves to be more effective than pushover based on single mode in case of medium rise r.c. frame building (higher than 30 metres) but, once this building is retrofitted, and therefore regularized, with a bracing system, the difference between using monomodal or multimodal pushover becomes not significant
