Role of Communication in Data Reuse

In acknowledging the potentials of existing data, researchers’ interests in sharing and reusing data have recently emerged. However, sharing and reusing data is not a simple one-step process for researchers. Because data reusers build their work on other researchers’ findings, the process of data reuse involves various interactions and communications with other relevant parties. Exploring the nature of communications around data is thus important to fully understand data reuse practices and to support smoother processes of data reuse. This study investigates communications occurring around data during data reusers’ experiences through qualitative interview studies involving this group. This study’s results show that the communications with different stakeholders mainly support data reuse in three areas: searching, learning, and problem solving. The findings provide valuable insights into the domain of scholarly communication, data reuse, and data services

Moreover, to account for the limited life-span of the wireless devices, harvesting the energy of the network transmissions provides significant benefits to the lifetime of such networks. In this paper, we study the performance of communication in dense networks with wireless energy harvesting (WEH)-enabled sensor nodes. In particular, we examine two different communication scenarios (direct and cooperative) for data exchange and we provide theoretical expressions for the probability of successful communication. Then, considering the importance of lifetime in WSNs, we employ state-of-the-art WEH techniques and realistic energy converters, quantifying the potential energy gains that can be achieved in the network. Our analytical derivations, which are validated by extensive Monte-Carlo simulations, highlight the importance of WEH in dense networks and identify the tradeoffs between the direct and cooperative communication scenarios.Peer ReviewedPostprint (author's final draft

Open data governance: civic hacking movement, topics and opinions in digital space

AbstractThe expression 'open data' relates to a system of informative and freely accessible databases that public administrations make generally available online in order to develop an informative network between institutions, enterprises and citizens. On this topic, using the semantic network analysis method, the research aims to investigate the communication structure and the governance of open data in the Twitter conversational environment. In particular, the research questions are: (1) Who are the main actors in the Italian open data infrastructure? (2) What are the main conversation topics online? (3) What are the pros and cons of the development and use (reuse) of open data in Italy? To answer these questions, we went through three research phases: (1) analysing the communication network, we found who are the main influencers; (2) once we found who were the main actors, we analysed the online content in the Twittersphere to detect the semantic areas; (3) then, through an online focus group with the main open data influencers, we explored the characteristics of Italian open data governance. Through the research, it has been shown that: (1) there is an Italian open data governance strategy; (2) the Italian civic hacker community plays an important role as an influencer; but (3) there are weaknesses in governance and in practical reuse

Reuse potential assessment framework for gamification-based smart city pilots

The paper proposes a unified framework for assessing the re-use potential for the Smart Engagement Pilot currently being realized in the city of Ghent (Belgium). The pilot aims to stimulate the digital engagement in users (citizens) by involving them in online and offline communities, and increasing the social capital through the use of ICT (Information and Communications Technology). To engage the citizens, the pilot makes use of Gamification based entities (intelligent wireless sensors) embedded in public hardware, through which innovative games are organized in places of interest (neighbourhood, parks, schools, etc.). Once finished, this pilot will be re-used in other European cities under the context of CIP SMART IP project. Since, the success of a pilot in one city doesn't guarantee its success in the other, an objective socio-economic-organizational reuse assessment becomes critical. To do this assessment, we propose a framework, which uses a Key Performance Indicator (KPI) based scorecard to determine the roadblocks and battlefields that could deter such a transition

How Governance Regimes Shape the Implementation of Water Reuse Schemes

The governance dimensions of water reuse scheme development and operation, such as policies and regulatory frameworks, and public involvement and stakeholder collaboration, can serve to both facilitate and constrain wider adoption of water reuse practices. This paper explores the significance and underlying structure of the key governance challenges facing the water reuse sector in Europe. It presents empirical evidence from interviews and focus group sessions conducted at four water reuse schemes: an indirect potable reuse scheme at Torreele (Belgium), the urban reuse of treated municipal wastewater at the London Olympic Park (United Kingdom) and at Sabadell (Spain), and the reuse of agro-industrial effluent for irrigation at Capitanata (Italy). The findings underscore the importance of clarity in policy arrangements around water reuse, as well as of the financial competitiveness of reuse projects compared to alternative water supply options. Operators of water reuse schemes expressed a preference for water quality standards, which focus on appropriateness for use rather than over-emphasise the waters’ origin so that unnecessary treatment and costs can be avoided. Positive public support was widely acknowledged as an important factor in the success or failure of water reuse schemes. We conclude that constructive institutional relationships underpin many of the challenges faced by reuse scheme operators and that greater emphasis should be given to building confidence and gaining trust in water service providers through early identification of how governance regimes shape the viability of new scheme

Europeana communication bug: which intervention strategy for a better cooperation with creative industry?

Although Europeana as well as many GLAMs are very engaged - beside the main mission, i.e. spreading cultural heritage knowledge- in developing new strategies in order to make digital contents reusable for creative industry, these efforts have been successful just only in sporadic cases. A significant know how deficits in communication often compromises expected outcomes and impact. Indeed, what prevails is an idea of communication like an enhancement “instrument” intended on the one hand in purely economic (development) sense, on the other hand as a way for increasing and spreading knowledge. The main reference model is more or less as follows: digital objects are to be captured and/or transformed by digital technologies into sellable goods to put into circulation. Nevertheless, this approach risks neglecting the real nature of communication, and more in detail the one of digital heritage where it is strategic not so much producing objects and goods as taking part into sharing environments creation (media) by engaged communities, small or large they may be. The environments act as meeting and interchange point, and consequently as driving force of enhancing. Only in a complex context of network interaction on line accessible digital heritage contents become a strategic resource for creating environments in which their re/mediation can occur – provided that credible strategies exist, shared by stakeholders and users. This paper particularly describes a case study including proposals for an effective connection among Europeana, GLAMs and Creative Industry in the framework of Food and Drink digital heritage enhancement and promotion. Experimental experiences as the one described in this paper anyway confirm the relevance of up-to-date policies based on an adequate communication concept, on solid partnerships with enterprise and association networks, on collaborative on line environments, on effective availability at least for most of contents by increasing free licensing, and finally on grassroots content implementation involving prosumers audience, even if filtered by GLAMs
