TEACHING AND RESEARCH: THE ERASMUS PLUS EXPERIENCE
No full textThe paper illustrates the dual experience of exchange Erasmus-Plus, conducted in collaboration between the Department of Architecture and Industrial Design of Università della Campania "L. Vanvitelli" and the National Technical University of Athens - School of Architecture, focusing not only on the positive impacts that the activity has had for the two university structures, but above all highlighting the added value for the two research groups that during this experience have compared the different teaching methods implemented in the dual exchange.
Infact, Lisboa strategy gives the human capital a central role in the process of social growth and it gives learning the function of essential tool in the management of both human sources and work qualification. In this scenario, the support from the Scientific Research world can be extremely meaningful for a didactic path, where the scientific knowledge is structured to orientate, qualify and substantiate teaching, both on the disciplinary contents level and on the methodological one. Therefore, the scientific support is configured not only under the pedagogic profile, but also above all as a support structured to acquire specific knowledge/competence. This is to favour the most rightful and complete acquaintance of knowledge gained and scientifically tested by experts of the sector, who, as professors, can transfer their theoretical knowledge, practical experiences and specialist disciplinary skills.
No learning path can be considered highly qualified if high competency is not used, besides a punctual transfer of didactic contents, which will manage to maximize the learning process working not only on contents but also on competence. The Erasmus Plus, approved by the EU Regulation N.1288/2013, is designed to give concrete answers to these issues, through educational opportunities, abroad training, which puts providentially comparing educational and international research experience and interdisciplinary methods.
This paper describes the twofold didactic path implemented through methodologies aimed at developing specialized skills in the field of energy efficient and environmentally sustainable buildings, based on laboratory teaching, problem solving approach and design of technological solutions in teams, through the use of specialized software for decision support

Copyright @ 2010 Elsevier B.V.This paper introduces the possibility of in situ assessment of loading and remaining strength in concrete structures by means of measuring discharge of electric current from loaded specimens.
The paper demonstrates that the techniques have been applied to other rock-like materials, but that for the first time they are applied to cement-based materials and a theoretical model is proposed in relation to the appearance of electrical signals during sample loading and up to fracture.
A series of laboratory experiments on cement mortar specimens in simple uniaxial compression, and subsequently in bending – hence displaying both tension and compression – are described and show clear correlations between resulting strains and currents measured. Under uniaxial loading there is a well-defined relationship between the pressure-stimulated current (PSC) as a result of a monotonic mechanical loading regime. Similar results are observed in the three-point bending tests where a range of loading regimes is studied, including stepped changes in loading.
While currents can be measured at low strains, best results seem to be obtained when strains approach and exceed yield stress values.
This technique clearly has immense potential for structural health monitoring of cement-based structures. Both intermittent and continuous monitoring becomes possible, and given an ongoing campaign of monitoring, remaining strength can be estimated
Injonctions métropolitaines : grands projets de transformation urbaine et jeux institutionnels
No full textIl capitolo considera alcuni elementi di continuità e di rottura nella governance delle metropoli dell'Europa meridionale, cercando di capire come esse stiano rispondendo ai vari “sconvolgimenti” contingenti o sistemici che si sono verificati a partire dalla crisi subprime del 2008. Queste forze sembrano favorire intensi processi di metropolizzazione e regionalizzazione dell'urbano, che influenzano la rete tra gli attori istituzionali a diversi livelli e il campo dei meccanismi di trasformazione spaziale metropolitana. L'attenzione si concentra sui progetti di sviluppo urbano su larga scala perché rivelano una dinamica complessa e contestata che ha interessato le città dell'Europa meridionale in modi diversi. Infatti, i casi esplorati di Atene, Madrid, Milano e Roma evidenziano il coinvolgimento di una serie complessa di attori globali e locali e l'emergere di un approccio neoliberale alla pianificazione e alla politica urbana, che ha portato alla privatizzazione di beni e servizi e, nel processo, alla finanziarizzazione del territorio urbano.The chapter considers some elements of continuity and rupture in the governance of the metropolis of Southern Europe, trying to understand how they are responding to the various contingent or systemic ‘upheavals’ that have occurred since the 2008 subprime crisis. These forces seem to foster intense processes of metropolisation and regionalisation of the urban, which affect the network between institutional actors at different levels and the field of the mechanisms of metropolitan spatial transformation. The focus is on large-scale urban development projects because they reveal a complex and contested dynamic that has affected the cities of Southern Europe in different ways. Indeed, the cases explored in Athens, Madrid, Milan and Rome highlight the involvement of a complex array of global and local actors and the emergence of a neo-liberal approach to urban planning and policy, which has led to the privatisation of goods and services – and, in the process, to the financialisation of urban land.Le chapitre analyse la gouvernance des métropoles d’Europe du Sud à travers leurs continuités et leurs ruptures et comment ces villes répondent aux bouleversements – contingents ou systémiques – apparus après la crise des « subprimes ».

L’accent est ici porté sur les grands projets de développement car ils sont révélateurs d’une dynamique complexe et controversée. En effet, les exemples explorés à Athènes, Madrid, Milan et Rome mettent en évidence un jeu complexe d’acteurs globaux et locaux et l’affirmation d’une approche néolibérale de la planification et des politiques urbaines.

La progettazione tecnologica e ambientale: Italia e Grecia a confronto | Technological and environmental design: Italy and Greece in comparison
No full textAs an answer to new challenges concerning the role of
the architect in future societies, a new approach to the
teaching of technological and environmental design was
developed by an interdisciplinary team of academics,
involving a reconsideration of the basic concepts and
strategies in architectural design and its interaction both
with natural and built environment and users. A new
methodology has tested in technological and environ-
mental design courses taught to students of the Technical
University of Athens (School of Civil Engineering) and
the University of Campania (Department of Architecture
and Industrial Design) in comparison, where the analysis
of environmental parameters is based not only on perfor-
mance assessment, but also on the evaluation of environ-
mental comfort for users

Development of a measurement-based approach for monitoring the changes in an evolving quality management system
No full textThe concept of quality management is operationalized in an organization through a Quality Management System (QMS) - a complex, coordinated set of activities and behaviors aimed at improving the quality of an organization's processes, goods, and services. Like all systems, a QMS must be planned, monitored, improved, and maintained over time to function at its best. For this, measurement is key.
The standard of quality management performance developed by Triantis, et. al. (1991b) is the quality management system definition used in this thesis. The thesis subsequently makes three contributions. First, it provides a methodology for defining generic measures of QMS performance and evolution, and implements this methodology in creating more than 200 prototype measures for 10 out off the 37 component "modules" of a QMS. Second, a methodology is presented for developing a tool to collect the very data called for by the measures. This methodology is implemented and a prototype questionnaire developed to collect measurement data for the Vendor/Contractor Relations (VCR)module of a QMS. Third, given the vast amount of data collected with the various questionnaires that needs to be manipulated in order to manage the QMS, it is important to be able to use automation. Therefore, it becomes necessary to logically organize the data. The entity-relationship (E/R) modeling technique is one approach that can be used to achieve this objective. This E/R approach is used to logically organize data that is generated by the questionnaire for the VCR module. In so doing, one can assess the potential viability of this data modeling approach and begin laying the foundation for a database that will support the measurement requirements of a QMS.Master of Scienc
Optimal Incentive Contracts under Moral Hazard When the Agent is Free to Leave
No full textWe characterize optimal incentive contracts in a moral hazard framework extended in two directions. First, after effort provision, the agent is free to leave and pursue some ex-post outside option. Second, the value of this outside option is increasing in effort, and hence endogenous. Optimal contracts may entail properties such as inducing first-best effort and surplus, or non-responsiveness with respect to changes in verifiable parameters. Moreover, while always socially inefficient, separation might occur in equilibrium. Except for the latter, these findings are robust to renegotiation. When the outside option is exogenous instead, the standard results obtain.moral hazard; limited commitment; ex-post outside option; limited liability
