La comunicazione della cooperazione allo sviluppo: gli Enti Pubblici. Analisi discorsive dei Siti Web

Our research takes place in the context of a discipline kwown as Communication for Development, sited inside the field of Communication for Social Change, characterized by the use of interpersonal ad mass communication theories and tools, applyied to international development cooperation. Our study aims at pointing out a change of paradigm in this field: our object is Public Administration’s communication, therefore, what we suggest is a shift from Communication for Development, to Development Communication. The object of our study, hence, becomes the discourse itself, in its double action of representation and construction of reality. In particular, we are interested in the discourse’s tribute to the creation of a collective immagination, wich is the perspective towards which we have oriented the analysis, through a structuralist semoitics-based methodology integrated with a socio-semiotic approach. Taking into consideartion the fact that in our contemporary society (that is to say a ‘Western’ and ‘First World’ society), the internet is a crucial public space for the mediation and the management of collective immagination, we chose the web sites of Public Bodies which are dedicated to International Cooperation has our analysis corpus. This, due to their symbolic and ideologic significance, as well as for the actual political responsibility we think these web sites should have. The result of our analysis allows us to suggest some discoursive strategies used in the web sites of Public Bodies. In these sites, there is a tendency to shift the discourses around international cooperation from the ideological axis - avoiding in so doing to explicit a political statement about the causes of injustices and un-balances which lead to the necessity of a support in development (i.e. avoiding to mention values such as social justice and democracy while acknowledging socio-economical institutions which contribute to foster underdevelopment on a global scale) -, to the ethical axis, hence referring to moral values concerning the private sphere (human solidarity and charity), which is delegated mainly to non governamental associations.

Middleware principles and design for the integration of ubiquitos mobile services

Nowadays, in Ubiquitous computing scenarios users more and more require to exploit online contents and services by means of any device at hand, no matter their physical location, and by personalizing and tailoring content and service access to their own requirements. The coordinated provisioning of content tailored to user context and preferences, and the support for mobile multimodal and multichannel interactions are of paramount importance in providing users with a truly effective Ubiquitous support. However, so far the intrinsic heterogeneity and the lack of an integrated approach led to several either too vertical, or practically unusable proposals, thus resulting in poor and non-versatile support platforms for Ubiquitous computing. This work investigates and promotes design principles to help cope with these ever-changing and inherently dynamic scenarios. By following the outlined principles, we have designed and implemented a middleware support platform to support the provisioning of Ubiquitous mobile services and contents. To prove the viability of our approach, we have realized and stressed on top of our support platform a number of different, extremely complex and heterogeneous content and service provisioning scenarios. The encouraging results obtained are pushing our research work further, in order to provide a dynamic platform that is able to not only dynamically support novel Ubiquitous applicative scenarios by tailoring extremely diverse services and contents to heterogeneous user needs, but is also able to reconfigure and adapt itself in order to provide a truly optimized and tailored support for Ubiquitous service provisioning.

Sviluppo di tecniche per la progettazione delle reti di monitoraggio della qualita' dell'aria

L’obiettivo del lavoro consiste nell’implementare una metodologia operativa volta alla progettazione di reti di monitoraggio e di campagne di misura della qualità dell’aria con l’utilizzo del laboratorio mobile, ottimizzando le posizioni dei dispositivi di campionamento rispetto a differenti obiettivi e criteri di scelta. La revisione e l’analisi degli approcci e delle indicazioni fornite dalla normativa di riferimento e dai diversi autori di lavori scientifici ha permesso di proporre un approccio metodologico costituito da due fasi operative principali, che è stato applicato ad un caso studio rappresentato dal territorio della provincia di Ravenna. La metodologia implementata prevede l’integrazione di numerosi strumenti di supporto alla valutazione dello stato di qualità dell’aria e degli effetti che gli inquinanti atmosferici possono generare su specifici recettori sensibili (popolazione residente, vegetazione, beni materiali). In particolare, la metodologia integra approcci di disaggregazione degli inventari delle emissioni attraverso l’utilizzo di variabili proxy, strumenti modellistici per la simulazione della dispersione degli inquinanti in atmosfera ed algoritmi di allocazione degli strumenti di monitoraggio attraverso la massimizzazione (o minimizzazione) di specifiche funzioni obiettivo. La procedura di allocazione sviluppata è stata automatizzata attraverso lo sviluppo di un software che, mediante un’interfaccia grafica di interrogazione, consente di identificare delle aree ottimali per realizzare le diverse campagne di monitoraggio
