Maritime Silk Road e connessioni mediterranee, gli attuali scenari
No full textMaritime silk road and mediterranean connections, the current scenarios – The
construction of the 21st century Maritime Silk Road is intensifying global connections. Europe is the
final landing place of this route and this has led to a shift of Chinese interests towards ports and other
infrastructures throughout the maritime route from East to West. The centrality of the Mediterranean
Sea is therefore increasingly evident
Colonia portoghese, avamposto della Guerra Fredda, Regione Amministrativa Speciale cinese. Vecchi e nuovi confini di Macao nella cartografia storica e nelle descrizioni odeporiche italiane
No full textMacao, posta nell’estuario del Fiume delle Perle, a partire dall’età moderna rappresentò il punto d’ingresso dell’Occidente in Cina. Riconosciuto come possedimento coloniale portoghese a partire dal 1557-1558 circa, l’insediamento lusitano (di fatto, una “città-colonia”) si sviluppò sull’estremità meridionale dell’isola omonima, mentre il cordone di terra che lo collegava al grosso della massa insulare fu sbarrato da mura attraversate da una sola porta, la Porta do Cerco. Per secoli, tale varco funse come unico accesso per la gran parte degli occidentali diretti nell’Impero cinese e transitati per Macao. Questo confine si è perpetuato sino ad oggi, assumendo via via connotazioni e implicazioni differenti. Il contributo analizza, in una prospettiva di lungo periodo, la rappresentazione e la percezione di questo confine atipico e polisemico nella cartografia storica e nella letteratura di viaggio italiane
Application of duplex stainless steel for welded bridge construction in aggressive environment
No full textMaintenance costs are a significant item in life cycle of steel bridges, becoming of paramount importance in aggressive environments. The use of duplex stainless steels for bridge decks would be a major step forward in providing durable, low maintenance structures, exploiting both their corrosion resistance and high mechanical properties, capable of meeting in full the required structural safety performances. A research project partially funded by the EU research programme RFCS (Research Funct for Coal and Steel, Bridgeplex contract RFS-CR-04040) is developing technical information on the use of duplex stainless steel in welded bridge construction via mechanical testing and numerical analyses, so as to provide indications suitable to form the basis for an upgrade of Eurocode 3 [1] and to allow a reliable Life Cycle Cost analysis for this kind of structures so as to address the best material choice for the future bridges. The project is still in progress but first results are available. This paper gives an overview of the project and summarizes results obtained, deeper detailed in other papers presented at the International Conference Duplex 2007 ([5] and [6]). In particular the paper is concerned with: overview of critical details in a welded bridge deck and relevant data available in literature also on austenitic and austeno-ferritic steels; and economical evaluations considering maintenance aspects and fabrication costs showing the advantages of the application of duplex stainless steel to defined bridge typologies

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
L'esperienza della Cooperativa sociale "La Paranza" per un progetto di comunità urbana contemporanea tra animazione e ricostruzione dei legami sociali.
No full textL’attuale spazio urbano è dominato da confini che esasperano la comune convivenza, alimentando la distanza sociale. L’obiettivo del contributo è illustrare, in un’ottica socio-spaziale, il lavoro di valorizzazione del patrimonio artistico - culturale del quartiere Rione Sanità di Napoli svolto dalla Cooperativa Sociale “La Paranza”, al fine di favorire l’attraversamento di confini simbolici e costruire forme di appartenenza territoriale fondate sulla comune cittadinanza locale
