In order to sustain human life for extended periods of time in deep space one cannot solely rely on support from Earth. It'll be essential to become self-sustaining through a combination of in situ resource utilization, waste recycling, and space farming. The latter can provide astronauts and colonists with locally grown food and biogenic oxygen, and will be an indispensable component of any future outpost in deep space. The type of agriculture that will develop itself in outer space will be extremely technologically mediated because of limited resources and the hostile conditions in which crops have to be cultivated. From a biopolitics perspective, this will cause a significant shift in power relations. Because of the extreme dependence on technology, the lack of open reservoirs (e.g., no atmosphere), and an atomized commodification of life-supporting resources (every molecule is valuable), space colonists will live in a world in which they are potentially vulnerable to inequalities, power concentrations, and even coercion. Historically, colonization and agriculture have always worked with each other. But in the unparalleled conditions of space, this dialectic relationship is bound to take on new contours, with its own unique set of ideologies and ethical ramifications. The 'Space Farming Project' is an art project that specifically addresses these issues. It was initiated by the international SEAD collective, developed in collaboration with Gluon and Howest, and supported by the Flemish Government. Together with a diverse community of volunteering technologists, agricultural researchers, teachers, and students, different space biology prototypes have been developed: a centrifuge for plant cultivation in space, a microgravity simulator, and experiments with spirulina algae and edible callus tissue. These are the central components of a larger art installation that also features visual and discursive references to the history and future of colonization, and its entwinement with agriculture. In this paper, the conceptual background of the 'Space Farming Project' is described, together with its development process and the resulting prototypes. The future of the project, with potential experiments on board the ISS, is also discussed.

This paper focuses on the particular power of storytelling to foster reflection and connections between people in urban life. In fact, the core principles and mechanisms for public storytelling to achieve this have yet to be made explicit. This gap is addressed by introducing a novel reflective storytelling framework that unveils the underlying principles of fostering reflection and connection through public storytelling. The framework is proposed on the basis of the literature and its appropriateness is explored in a case study in the Hague (the Netherlands) with particular focus on the influence of content and form on successfully orchestrating reflective storytelling. The impact of citizen stories on the creation of new and stronger social ties, as well as challenges, tensions, and opportunities are discussed. These results inform researchers, urban planners, and other city practitioners on how to design effective storytelling initiatives to strengthen ties in urban communities.System EngineeringTransport and Logistic

This book represents the combined peer-reviewed proceedings of the Fifth International Symposium on Intelligent Distributed Computing -- IDC 2011 and of the Third International Workshop on Multi-Agent Systems Technology and Semantics -- MASTS 2011. Both events were held in Delft, The Netherlands during October 5-7, 2011. The 33 contributions published in this book address many topics related to theory and applications of intelligent distributed computing and multi-agent systems, including: adaptive and autonomous distributed systems, agent programming, ambient assisted living systems, business process modeling and verification, cloud computing, coalition formation, decision support systems, distributed optimization and constraint satisfaction, gesture recognition, intelligent energy management in WSNs, intelligent logistics, machine learning, mobile agents, parallel and distributed computational intelligence, parallel evolutionary computing, trust metrics and security, scheduling in distributed heterogenous computing environments, semantic Web service composition, social simulation, and software agents for WSNs.

Knowledge management is a critical issue in today's business world. Knowledge is considered to be one of the most strategic resources of a firm and sources of competitive advantage. This paper identifies and ranks Critical Success Factors (CSFs) for implementation of knowledge management in the Iranian Energy Sector. Using the Analytic hierarchy process (AHP) method the relative quantitative weights of 8 of the major CSFs for implementation of knowledge management are identified, based on analyses with KM designers in the Iranian energy sector. The outcomes of the research designate that the critical success factors in the order of importance are: corporate culture, human and financial resources, strategy and leadership, structures and procedures, meso environmental factors, knowledge management process, macro environmental factors, technology and infrastructure.

In today’s world large distributed ICT is affecting many processes of individual and societal developments. Driven by new technology new types of systems are emerging participatory systems systems that have acquired power and agency. At first such systems most often initiate within communities of practice. Some succeed, some don't (the leading principle seems to be based on trial and error). Defining ‘participatory systems’ as (large scale) ICT enabled social-technological-ecological systems in today's networked society, designed with a mission, to provide a technological, social and ecological infrastructure to support participation provides the grounds for a framework. This framework provides a methodology for value-based design (including analysis) of the structure, networks and governance within a networked system, including accepted design principles and constructs for the design of function, structure, behavior which is extended with human experience (artistic research...

This paper addresses the challenges of providing customized collaboration support to teams of experts. Current groupware systems only provide support for workflow-based collaboration, avoiding new forms of collaboration such as emergent collaboration. Therefore this paper proposes a elastic collaboration approach and its implementation in a groupware system.

Bioregenerative life support systems (BLSS) are vital for long-duration and remote space missions to increase mission sustainability. These systems break down human waste materials into nutrients and CO2 for plants and other edible organisms, which in turn provide food, fresh water, and oxygen for astronauts. The central idea is to create a materially closed loop, which can significantly reduce mission mass and volume by cutting down or even eliminating disposable waste. In most BLSS studies only a fraction of the resources, such as food, are provided by the system itself, with the rest taken on board at departure or provided through resupply missions. However, for autonomous long-duration space missions without any possibility of resupply, a BLSS that generates all resources with minimal or no material loss, is essential. The goal of this study is to develop a stoichiometric model of a conceptually fully closed BLSS that provides all the metabolic needs of the crew and organisms. T...

COVID-19 has urged researchers to explore new options for distributed participatory design, as physical meetings and workshops became unfeasible. This situation posed new challenges but also opportunities, in particular with respect to engagement and inclusion. This paper focuses on distributed PD with Irish teenagers to support place-making during this period: to build relationships with each other and the community. In a two-week online summer school, teenagers explored a concern or highlighted a unique aspect of their local community and designed digital artworks in response. Activities and materials were designed to support reflection, empowerment, inclusiveness, emergence, and playfulness for participatory place-making. Analysis of the summer school provides insights and guidance on the design of online PD for engaging experiences, especially in the context of place-making.
