    According to the IST/ FET proactive initiative on GLOBAL COMPUTING, the goal is to obtain techniques (models, frameworks, methods, algorithms) for constructing systems that are flexible, dependable, secure, robust and efficient. The dominant concerns are not those of representing and manipulating data efficiently but rather those of handling the co-ordination and interaction, security, reliability, robustness, failure modes, and control of risk of the entities in the system and the overall design, description and performance of the system itself. Completely different paradigms of computer science may have to be developed to tackle these issues effectively. The research should concentrate on systems having the following characteristics: • The systems are composed of autonomous computational entities where activity is not centrally controlled, either because global control is impossible or impractical, or because the entities are created or controlled by different owners. • The computational entities are mobile, due to the movement of the physical platforms or by movement of the entity from one platform to another. • The configuration varies over time. For instance, the system is open to the introduction of new computational entities and likewise their deletion. The behaviour of the entities may vary over time. • The systems operate with incomplete information about the environment. For instance, information becomes rapidly out of date and mobility requires information about the environment to be discovered. The ultimate goal of the research action is to provide a solid scientific foundation for the design of such systems, and to lay the groundwork for achieving effective principles for building and analysing such systems. This workshop covers the aspects related to languages and programming environments as well as analysis of systems and resources involving 9 projects (AGILE , DART, DEGAS , MIKADO, MRG, MYTHS, PEPITO, PROFUNDIS, SECURE) out of the 13 founded under the initiative. After an year from the start of the projects, the goal of the workshop is to fix the state of the art on the topics covered by the two clusters related to programming environments and analysis of systems as well as to devise strategies and new ideas to profitably continue the research effort towards the overall objective of the initiative. We acknowledge the Dipartimento di Informatica and Tlc of the University of Trento, the Comune di Rovereto, the project DEGAS for partially funding the event and the Events and Meetings Office of the University of Trento for the valuable collaboration

    Observing Environments

    > Context • Society is faced with “wicked” problems of environmental sustainability, which are inherently multiperspectival, and there is a need for explicitly constructivist and perspectivist theories to address them. > Problem • However, different constructivist theories construe the environment in different ways. The aim of this paper is to clarify the conceptions of environment in constructivist approaches, and thereby to assist the sciences of complex systems and complex environmental problems. > Method • We describe the terms used for “the environment” in von Uexküll, Maturana & Varela, and Luhmann, and analyse how their conceptions of environment are connected to differences of perspective and observation. > Results • We show the need to distinguish between inside and outside perspectives on the environment, and identify two very different and complementary logics of observation, the logic of distinction and the logic of representation, in the three constructivist theories. > Implications • Luhmann’s theory of social systems can be a helpful perspective on the wicked environmental problems of society if we consider carefully the theory’s own blind spots: that it confines itself to systems of communication, and that it is based fully on the conception of observation as indication by means of distinction

    Transdisciplinarity seen through Information, Communication, Computation, (Inter-)Action and Cognition

    Full text link
    Similar to oil that acted as a basic raw material and key driving force of industrial society, information acts as a raw material and principal mover of knowledge society in the knowledge production, propagation and application. New developments in information processing and information communication technologies allow increasingly complex and accurate descriptions, representations and models, which are often multi-parameter, multi-perspective, multi-level and multidimensional. This leads to the necessity of collaborative work between different domains with corresponding specialist competences, sciences and research traditions. We present several major transdisciplinary unification projects for information and knowledge, which proceed on the descriptive, logical and the level of generative mechanisms. Parallel process of boundary crossing and transdisciplinary activity is going on in the applied domains. Technological artifacts are becoming increasingly complex and their design is strongly user-centered, which brings in not only the function and various technological qualities but also other aspects including esthetic, user experience, ethics and sustainability with social and environmental dimensions. When integrating knowledge from a variety of fields, with contributions from different groups of stakeholders, numerous challenges are met in establishing common view and common course of action. In this context, information is our environment, and informational ecology determines both epistemology and spaces for action. We present some insights into the current state of the art of transdisciplinary theory and practice of information studies and informatics. We depict different facets of transdisciplinarity as we see it from our different research fields that include information studies, computability, human-computer interaction, multi-operating-systems environments and philosophy.Comment: Chapter in a forthcoming book: Information Studies and the Quest for Transdisciplinarity - Forthcoming book in World Scientific.

    Convergence science in the Anthropocene: Navigating the known and unknown

    Get PDF
    Rapidly changing ecological and social systems currently pose significant societal challenges. Navigating the complexity of social-ecological change requires ap- proaches able to cope with, and potentially solve, both foreseen and unforeseen societal challenges. The emergent field of convergence addresses the intricacies of such challenges, and is thus relevant to a broad range of interdisciplinary issues. This paper suggests a way to conceptualize convergence research. It discusses how it relates to two major societal challenges (adaptation, transformation), and to the generation of policy-relevant science. It also points out limitations to the further development of convergence research

    Fostering Emotional Engineers: Revisiting Constructive Thinking in Engineering Education

    Get PDF
    For the past decade, engineering education efforts at the postsecondary level have sought to create a more holistic type of critical thinker (Felder & Brent, 2015; Grasso & Burkins, 2010). As part of this initiative, engineers are encouraged to develop skills associated with constructive thinking—a pedagogical concept rooted in the belief that knowledge is constructed through continual interaction with peers and the environment (Anderson, 2013; Driscoll, 2005; Shayer, 2003). However, despite the positive ramifications linked with this pedagogical shift, studies have demonstrated that the increased use of collaborative aspects associated with constructivist teaching practices may be negatively impacting female students (Rosser, 2009; Tonso, 1996; Wolfe & Powell, 2009a, 2009b). Taking a primarily philosophical approach, the contribution of emotions to constructive thinking is explored utilizing Thayer-Bacon’s (2000) conceptualization of the concept to argue that the pedagogical shift within engineering has not fully incorporated a holistic approach to learning. The results of recent studies in engineering education are analyzed to highlight the negative consequences associated with overlooking emotions as contributors to constructive thinking primarily for female students in the field (Jones et al., 2013; Tonso, 1996, 2006; Wolfe & Powell, 2006). To conclude, the value of emotions for the engineering discipline is underscored by using work by Jaggar (1992, 1998) to explore its historical association with female thought and its overall impact on the construction of knowledge

    Understanding the nature and significance of early childhood: new evidence and its implications

    Get PDF
    INTRODUCTION This paper is based on a presentation at a Centre for Community Child Health seminar devoted to a consideration of the Productivity Commission’s Draft Report on Child Care and Early Childhood Learning. The aim of the paper was to present a succinct summary of relevant evidence to inform discussions. Rather than reviewing the evidence regarding existing forms of service, the presentation focused more broadly on what we know about child development – how children learn and what children need. The paper is not so much about challenging existing models of early childhood education and care in Australia as challenging our understanding of the nature and significance of the early years. NEW RESEARCH EVIDENCE AND WHAT IT TELLS US Over the past few decades, there has been a growing acceptance among scholars, professionals and policy makers of the importance of the early years. However, as we learn more about the way in which experiences in the early years shape health, development and wellbeing, and the extent of these influences over the life-course, the true importance of these years becomes more and more apparent. There are nine sources of evidence to be considered. Evidence about the nature and significance of prenatal development and experiences, and their effects over the life course Evidence about the nature and significance of postnatal learning and development, and the impact of proximal environments Evidence regarding the impact of early childhood experiences on long term development, health and wellbeing Evidence regarding neurological development and plasticity Evidence regarding the neurobiology of interpersonal relationships Evidence regarding ‘social climate change’ and its effects Evidence from economic analyses of child development and the benefits of investments in the early years Evidence regarding social inequalities and their effects Evidence from repeated measurement of key indicators of child development and functioning.• Presentation at Centre for Community Child Health seminar Investing in Early Childhood—the future of early childhood education and care in Australia The Royal Children’s Hospital, Melbourne, 25 July 201

    Digital Preservation, Archival Science and Methodological Foundations for Digital Libraries

    Get PDF
    Digital libraries, whether commercial, public or personal, lie at the heart of the information society. Yet, research into their long‐term viability and the meaningful accessibility of their contents remains in its infancy. In general, as we have pointed out elsewhere, ‘after more than twenty years of research in digital curation and preservation the actual theories, methods and technologies that can either foster or ensure digital longevity remain startlingly limited.’ Research led by DigitalPreservationEurope (DPE) and the Digital Preservation Cluster of DELOS has allowed us to refine the key research challenges – theoretical, methodological and technological – that need attention by researchers in digital libraries during the coming five to ten years, if we are to ensure that the materials held in our emerging digital libraries are to remain sustainable, authentic, accessible and understandable over time. Building on this work and taking the theoretical framework of archival science as bedrock, this paper investigates digital preservation and its foundational role if digital libraries are to have long‐term viability at the centre of the global information society.
