    Digital commons represent important alternative forms of technology production and sharing in contemporary network society. The article presents the main results of a qualitative study on a specific case of digital commons, Ninux.org, the largest wireless community network (CN) in Italy. CNs are distributed local communication infrastructures, generally built and self-managed by grassroots organisations. Empirical data has been gathered through a mix of qualitative techniques, including 14 in-depth interviews with key participants of four major local networks (Pisa, Bologna, Firenze and Roma), multi-sited ethnographic observations and documents analysis, with the aim to investigate par- ticipation processes in this project, paying particular attention to the discursive elements and material practices among participants. On the basis of the empirical research and drawing on a conceptual framework matured on the ridge between sociology of innovation and science and technology studies (S&TS), the article’s findings explore the complexity characterising the interaction between practices, technology and political visions involved in digital commons production. We argue that the adherence to the paradigm of commons enacts a complex socio-technical process, in which discourses about the governance of digital resources, political agendas and material technologies are mutually adjusted and continuously realigned to perform in practice an infrastructure as a common-pool resource

    Il progetto “Rewetland” (programma LIFE+ 2008 – environment and governance. www.rewetland.eu) prevede la predisposizione di un Programma di Riqualificazione Ambientale (PRA) della Pianura Pontina attraverso la sperimentazione di tecniche di fitodepurazione diffusa. Il PRA si basa sull’analisi approfondita del paesaggio a partire da quello delle bonifiche dei Papi (XV–XVII sec.), fino ad arrivare ai giorni nostri. La finalitĂ  dell’analisi del paesaggio Ăš stata quella di ricomporre gli elementi costituenti i diversi ambiti paesaggistici del territorio in quadri unitari, quanto piĂč possibile coerenti al loro interno e confrontabili tra loro per valutarne le qualitĂ  paesaggistiche, le trasformazioni avvenute nel tempo o in atto, le necessitĂ  di processi di riqualificazione, le potenzialitĂ  di assorbire nuovi interventi progettuali. L’utilizzo di strumenti gis Ăš stato indispensabile, sia per individuare le permanenze del paesaggio storico e rurale, sia per definire e valutare i possibili scenari di intervento. Le azioni, i progetti e gli interventi del PRA riguardano la rinaturalizzazione dei corsi d’acqua e la realizzazione di aree umide ed ecosistemi filtro e favoriscono l’attivazione di buone pratiche non solo per la gestione dei canali della bonifica ma anche per quella delle aziende agricole. La metodologia utilizzata ha permesso di interpretare le trasformazioni del paesaggio dell’Agro Pontino e nel contempo progettare interventi e azioni di riqualificazione ambientale che rispondano a molteplici esigenze/obiettivi: il miglioramento della qualitĂ  delle acque, il potenziamento della rete ecologica e della biodiversitĂ , la rigenerazione dei paesaggi tipici delle zone umide (re-wetland) che rappresentano la memoria del territorio."Rewetland" project (LIFE+ 2008 - environment and governance. www.rewetland.eu) requires the preparation of an Programma di Riqualificazione Ambientale (PRA) of the Pontine Plain through experimentation with techniques of widespread phytoremediation. The PRA is based on a thorough analysis of the landscape from those of the reclamation of the Popes (XV -XVII cent.), up to the present day. The aim of the landscape analysis has been to reconstruct the elements making up the different areas of the local landscape into unified framework, as much as possible internally coherent and comparable to each other in order to assess the quality of the landscape, the changes through time or now being implemented, the necessity of regeneration processes, the potentialities to absorb new project interventions. GIS software tools have been essential, both to identify the permanence of the historic and rural landscape, and to define and evaluate the possible intervention scenarios. PRA actions, projects and interventions regard the renaturalization of waterways and the creation of wetlands and ecosystem filters and promote the activation of good practices not only for the management of the drainage channels but also for the farms. The methodology used allowed us to read the changes in the landscape of the Pontine Plain and at the same time to design interventions and actions that respond to multiple environmental restoration needs and objectives: improvement of water quality, enhancement of biodiversity and the ecological network, regeneration of the typical landscapes of wetlands (re-wetland) that represent the memory of territory.Peer Reviewe

    L’informatizzazione e la divulgazione del Catasto Gregoriano e della cartografia storica di Roma

    Il progetto d’informatizzazione del Catasto Gregoriano Urbano di Roma ù stato avviato circa dieci anni fa, grazie a un finanziamento della Fondazione Cariplo, ed ù ora nella sua fase conclusiva. Il progetto ù stato realizzato dal Dipartimento di Studi Urbani dell’università di Roma Tre, dall’Archivio di Stato di Roma, dalla Sovrintendenza Capitolina e dall’Archivio Capitolino e l’attività di ricerca ha permesso di ricostruire l'immagine urbana ed archeologica della Roma preunitaria e post-unitaria. Le mappe del Catasto Gregoriano e i relativi brogliardi costituiscono la base del Sistema Informativo Geografico (GIS) al quale sono stati collegati altri documenti cartografici e documentali: la pianta di Roma di G.B. Nolli del 1748; un consistente numero di schede relative a documenti di archivio in materia di architettura urbana e archeologia; documenti iconografici sulla architettura della città storica. Il progetto intende conseguire un duplice obiettivo: realizzare un sistema informativo geografico in grado di contenere, gestire e divulgare i dati sulla città storica provenienti da fonti diverse; creare uno strumento web a carattere partecipativo e didattico destinato ad un’ampia platea di utenti e non solo a ricercatori e studiosi del settore. La piattaforma web e la banca dati geografica sono state integralmente realizzate con prodotti e software Open Source.The digitization of the Gregorian Urban Cadastre of Rome (Catasto Gregoriano Urbano di Roma) has started about ten years ago thanks to the funding by the Cariplo Foundation, and it is now in its final stage. The project has been implemented by the Department of Urban Studies of the “Roma Tre” University, the Archivio di Stato di Roma, the Sovrintendenza Capitolina and the Archivio Capitolino. The research has allowed to reconstruct the archaeological and urban image of Rome in the pre- and post-unification periods. The maps and registers of the Gregorian Cadastre represent the basis of the Geographic Information System (GIS), which has been linked to maps and documents from other sources: the 1748 map of Rome by G. B. Nolli, a substantial number of datasheets from archive documents related to buildings and archeology, other iconographic documents concerning the architecture of the old town. The project has a dual purpose: on the one hand, the implementation of a GIS able to store, manage and disseminate data about the historic city from different sources; on the other, the activation of a participatory and educational web tool open to a wide audience, not only to researchers and scholars of this particular field. The web platform and the geographic database have been fully implemented with Open Source products and software.Peer Reviewe

    Piani di Mitigazione e di Adattamento congiunti per affrontare il cambiamento climatico sulla costa adriatica. Il progetto Joint_SECAP

    Get PDF
    Climate change adaptation is currently a "hot topic" on the global scene. In 2013, the European Commission adopted an EU adaptation strategy that sets out the framework for strengthening Europe resilience to the impacts of climate change and in 2014 Mayors Adapt - the Covenant of Mayors (CoM) initiative on Climate Change Adaptation, engaged cities in taking action to adapt to climate change. Nevertheless, this initiative is still at its dawn; most SEAPs only address the urban / municipal level, thus lacking the necessary territorial synergies that can make mitigation and adaptation policies and actions really effective. Some common factors have influenced the lack of effectiveness in the implementation of SEAPs and SECAPs. Energy plans are often too generic, sectoral and not well integrated into each city specific features, based on incomplete data and not always coordinated to other existing local policies and plans. Then there is a general lack of public awareness and qualified human resources and the same for funding opportunities. Another common obstacle is recognised in the incomplete, unshared, scattered information regarding energy efficiency and adaptation actions. There is the urgent need to take into account the specific territorial contexts (as for the Mediterranean and Adriatic regions), and, especially for adaptation measures, to define new opportunities to integrate common territorial challenges into Joint Actions and financial strategies. These common challenges are the ones the Joint-Secap project (Interreg Itally-Croatia) seeks to tackle by offering support to local authorities (specifically those in coastal areas with major vulnerabilities) in order to facilitate the implementation of specific adaptation measures (information, planning and monitoring). This Project reflects the necessity to operate at a wider district level (the Italian and Croation Adriatic Coast) to better define strategies and actions for climate change adaptation, for those weather and climate changes and hydrogeological risks affecting coastal areas.It is structured into two main phases; the first phase is developed to the common methodology for Joint Actions definition and implementation and to share the basic knowledge of climate change adaptation strategies and energy efficiency measures. The second phase regards the design of a web platform to share information, to support planning activities and even to monitor results and ongoing actions

    Il critico scenario ambientale dell’Agro Pontino, afflitto da una progressiva perdita di funzionalità e diversità ecologica dell’agro-ecosistema, ha portato la Provincia di Latina a promuovere e sviluppare una serie di iniziative per la sua riqualificazione. Il contributo intende approfondire come la Provincia sia stata un laboratorio per sperimentare processi di governance collaborativa attraverso l’integrazione tra diversi strumenti. Tale percorso viene riportato al fine di evidenziare il ruolo chiave degli enti “intermedi” nei processi di governance; l’importanza del coordinamento da parte di un ente in grado di proporre e portare avanti una visione e una pianificazione strategica; la necessità dell’adeguata inclusione, partecipazione e condivisione dei processi pianificatori.The critical environmental scenario of Agro Pontino, characterized by a progressive loss of functionality and ecological diversity of the agro-ecosystem, has led the Province of Latina to promote and develop a series of initiatives for its rehabiliation. This paper aims to present the case of the Province as a laboratory for experimenting collaborative governance processes through the integration of different tools. This 20 years’ planning is deepened in order to highlight, in the governance processes, the key role of the "intermediate" bodies; the importance of having the coordination done by an institution capable of proposing and carrying out a strategic vision and planning; the need for an appropriate inclusion and participation of citizens and stakeholders

    Epineurial window is more efficient in attracting axons than simple coaptation in a sutureless (cyanoacrylate-bound) model of end-to-side nerve repair in the rat upper limb: Functional and morphometric evidences and review of the literature

    End-to-side nerve coaptation brings regenerating axons from the donor to the recipient nerve. Several techniques have been used to perform coaptation: microsurgical sutures with and without opening a window into the epi(peri)neurial connective tissue; among these, window techniques have been proven more effective in inducing axonal regeneration. The authors developed a sutureless model of end-to-side coaptation in the rat upper limb. In 19 adult Wistar rats, the median and the ulnar nerves of the left arm were approached from the axillary region, the median nerve transected and the proximal stump sutured to the pectoral muscle to prevent regeneration. Animals were then randomly divided in two experimental groups (7 animals each, 5 animals acting as control): Group 1: the distal stump of the transected median nerve was fixed to the ulnar nerve by applying cyanoacrylate solution; Group 2: a small epineurial window was opened into the epineurium of the ulnar nerve, caring to avoid damage to the nerve fibres; the distal stump of the transected median nerve was then fixed to the ulnar nerve by applying cyanoacrylate solution. The grasping test for functional evaluation was repeated every 10-11 weeks starting from week-15, up to the sacrifice (week 36). At week 36, the animals were sacrificed and the regenerated nerves harvested and processed for morphological investigations (high-resolution light microscopy as well as stereological and morphometrical analysis). This study shows that a) cyanoacrylate in end-to-side coaptation produces scarless axon regeneration without toxic effects; b) axonal regeneration and myelination occur even without opening an epineurial window, but c) the window is related to a larger number of regenerating fibres, especially myelinated and mature, and better functional outcomes

    Bottom-up Infrastructures: Aligning Politics and Technology in building a Wireless Community Network

    Get PDF
    Contemporary innovation in infrastructures is increasingly characterized by a close relationship between experts and lay people. This phenomenon has attracted the attention from a wide range of disciplines, including computer-supported cooperative work (CSCW), science and technology studies (S&TS), organization studies and participatory design (PD). Connecting to this broad area of research, the article presents a qualitative case study concerning the building and maintenance of a grassroots, bottom-up information infrastructure in Italy, defined as wireless community network (WCN). Methodologically, the research is based on qualitative interviews with participants to the WCN, ethnographic observations and document analysis. The aim of the article is to understand the alignment between the technical work implied in building this bottom-up infrastructure and the political and cultural frameworks that move people to participate to this project. Relying on the field of science & technology studies, and in particular on the notions of ‘inverse infrastructure’ and ‘research in the wild’, we disclose the WCN’s peculiar innovation trajectory, localized outside conventional spaces of research and development. Overall, the presentation of the qualitative and ethnographic data allows to point out a more general reflection on bottom-up infrastructures and to enrich the academic debate concerning bottom-up infrastructuring work and other similar typologies of collaborative design projects in the domain of infrastructures
