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
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Injonctions métropolitaines: grands projets de transformation urbaine et jeux institutionnels
No full textIl capitolo analizza la governance delle metropoli dell'Europa meridionale attraverso continuità e rotture e il modo in cui queste città stanno rispondendo agli sconvolgimenti - sia contingenti che sistemici - emersi in seguito alla crisi dei mutui subprime. 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 grandi progetti di sviluppo, perché rivelano una dinamica complessa e controversa. Gli esempi esplorati ad Atene, Madrid, Milano e Roma evidenziano una complessa interazione tra attori globali e locali e l'affermazione di un approccio neoliberale alla pianificazione e alle politiche urbane. Ciò sta portando alla privatizzazione di beni e servizi e, allo stesso tempo, 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 ».Des processus intenses de métropolisation et de régionalisation de l’urbain investissent aussi bien les réseaux d’acteurs institutionnels à différents niveaux que les mécanismes du changement spatial. 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. Celle-ci conduit à la privatisation des biens et des services et, dans le même temps, à la financiarisation du sol urbain

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
