    Questions related to Bitcoin and other Informational Money

    Get PDF
    A collection of questions about Bitcoin and its hypothetical relatives Bitguilder and Bitpenny is formulated. These questions concern technical issues about protocols, security issues, issues about the formalizations of informational monies in various contexts, and issues about forms of use and misuse. Some questions are formulated in the more general setting of informational monies and near-monies. We also formulate questions about legal, psychological, and ethical aspects of informational money. Finally we formulate a number of questions concerning the economical merits of and outlooks for Bitcoin.Comment: 31 pages. In v2 the section on patterns for use and misuse has been improved and expanded with so-called contaminations. Other small improvements were made and 13 additional references have been include

    Developing knowledge for real world problem scenarios : using 3D gaming technology within a problem-based learning framework

    Get PDF
    Problem-based learning is an instructional strategy that emphasises active and experiential learning through problem-solving activity. Using gaming technologies to embed this approach in a three-dimensional (3D) simulation environment provides users with a dynamic, responsive, visually engaging, and cost effective learning experience. Representing real world problems in 3D simulation environments develops knowledge and skills that are applicable to their resolution. The Simulation, User, and Problem-based Learning (SUPL) Design Framework was developed to inform the design of learning environments which develop problem-solving knowledge for real world application. This framework identifies design factors relative to the user, the problem-solving task, and the 3D simulation environment which facilitate the transfer, development, and application of problem-solving knowledge. To assess the validity of the SUPL Design Framework, the Fires in Underground Mines Evacuation Simulator (FUMES) was developed to train mining personnel in emergency evacuation procedures at the Challenger gold mine in South Australia. Two groups of participants representing experienced and novice personnel were utilised to ascertain the effectiveness of FUMES as a training platform in this regard. Findings demonstrated that FUMES accurately represented emergency evacuation scenarios in the Challenger mine. Participants were able to utilise existing real world knowledge in FUMES to resolve emergency evacuation problem-solving tasks and develop new knowledge. The effectiveness of the SUPL Design Framework was also demonstrated, as was the need to design learning environments to meet the learning needs of users rather than merely as static simulations of real world problems. A series of generalisable design guidelines were also established from these findings which could be applied to design problem-based learning simulations in other training contexts

    Responsible research and innovation in science education: insights from evaluating the impact of using digital media and arts-based methods on RRI values

    The European Commission policy approach of Responsible Research and Innovation (RRI) is gaining momentum in European research planning and development as a strategy to align scientific and technological progress with socially desirable and acceptable ends. One of the RRI agendas is science education, aiming to foster future generations' acquisition of skills and values needed to engage in society responsibly. To this end, it is argued that RRI-based science education can benefit from more interdisciplinary methods such as those based on arts and digital technologies. However, the evidence existing on the impact of science education activities using digital media and arts-based methods on RRI values remains underexplored. This article comparatively reviews previous evidence on the evaluation of these activities, from primary to higher education, to examine whether and how RRI-related learning outcomes are evaluated and how these activities impact on students' learning. Forty academic publications were selected and its content analysed according to five RRI values: creative and critical thinking, engagement, inclusiveness, gender equality and integration of ethical issues. When evaluating the impact of digital and arts-based methods in science education activities, creative and critical thinking, engagement and partly inclusiveness are the RRI values mainly addressed. In contrast, gender equality and ethics integration are neglected. Digital-based methods seem to be more focused on students' questioning and inquiry skills, whereas those using arts often examine imagination, curiosity and autonomy. Differences in the evaluation focus between studies on digital media and those on arts partly explain differences in their impact on RRI values, but also result in non-documented outcomes and undermine their potential. Further developments in interdisciplinary approaches to science education following the RRI policy agenda should reinforce the design of the activities as well as procedural aspects of the evaluation research

    Defence science and innovation: an affordable strategic advantage

    Get PDF
    Overview: Australia’s neighbours in the Asia–Pacific are building high-quality science, technology, engineering and mathematics research capacities and infrastructure. As a consequence, Australia’s technological advantage in the defence domain is eroding. To recover that advantage, our policy should be to make the most of the knowledge, capability and capacity in Australia’s civilian science and innovation sector.  This special report analyses current and prospective Australian science, industry and defence science and innovation policy

    Challenges in Complex Systems Science

    Get PDF
    FuturICT foundations are social science, complex systems science, and ICT. The main concerns and challenges in the science of complex systems in the context of FuturICT are laid out in this paper with special emphasis on the Complex Systems route to Social Sciences. This include complex systems having: many heterogeneous interacting parts; multiple scales; complicated transition laws; unexpected or unpredicted emergence; sensitive dependence on initial conditions; path-dependent dynamics; networked hierarchical connectivities; interaction of autonomous agents; self-organisation; non-equilibrium dynamics; combinatorial explosion; adaptivity to changing environments; co-evolving subsystems; ill-defined boundaries; and multilevel dynamics. In this context, science is seen as the process of abstracting the dynamics of systems from data. This presents many challenges including: data gathering by large-scale experiment, participatory sensing and social computation, managing huge distributed dynamic and heterogeneous databases; moving from data to dynamical models, going beyond correlations to cause-effect relationships, understanding the relationship between simple and comprehensive models with appropriate choices of variables, ensemble modeling and data assimilation, modeling systems of systems of systems with many levels between micro and macro; and formulating new approaches to prediction, forecasting, and risk, especially in systems that can reflect on and change their behaviour in response to predictions, and systems whose apparently predictable behaviour is disrupted by apparently unpredictable rare or extreme events. These challenges are part of the FuturICT agenda

    Game Theory and Prescriptive Analytics for Naval Wargaming Battle Management Aids

    NPS NRP Technical ReportThe Navy is taking advantage of advances in computational technologies and data analytic methods to automate and enhance tactical decisions and support warfighters in highly complex combat environments. Novel automated techniques offer opportunities to support the tactical warfighter through enhanced situational awareness, automated reasoning and problem-solving, and faster decision timelines. This study will investigate how game theory and prescriptive analytics methods can be used to develop real-time wargaming capabilities to support warfighters in their ability to explore and evaluate the possible consequences of different tactical COAs to improve tactical missions. This study will develop a conceptual design of a real-time tactical wargaming capability. This study will explore data analytic methods including game theory, prescriptive analytics, and artificial intelligence (AI) to evaluate their potential to support real-time wargaming.N2/N6 - Information WarfareThis research is supported by funding from the Naval Postgraduate School, Naval Research Program (PE 0605853N/2098). https://nps.edu/nrpChief of Naval Operations (CNO)Approved for public release.
