    Social Navigation in a Location-Based Information System

    Much of contextaware application research has dealt with the technical aspects of context capturing and how to interpret the context of a user. Little effort has been spent on the experience and usage of these systems. This thesis will present the general aspects of social awareness and present an example on how these concepts can be implemented into a location-based information system to help users navigate a potential information overload. This thesis also states that giving the users an experience of not being alone in the system increases the pleasure of using such a system. However this implies a decrease in privacy. To demonstrate these ideas I will describe a locationbased information system, GeoNotes, built by a group of researchers at SICS, the Swedish Institute of Computer Science. I will state a set of interaction requirements for how to extend the GeoNotes system with functionality for social awareness. Furthermore I will set up functional requirements for those interaction requirements to after implementation be able to conclude which interaction requirements I have been able to implement for. I will also give suggestions on how to position users in a WLAN. The deliverable from this project is a locationbased information system with functionality for social awareness. However, it was not within this project to test the system on true users. Therefore the statement that this functionality can help users to navigate a potential information overload is still just a hypothesis. To retrieve the position of a user in a W-LAN a packet is sent to all base stations in the network. In the first returning packet the mac address of contacting base station is extracted. Each base station is therefore a unique position. Triangulation was discarded due to its sensitivity to noise and weather circumstances, although a system that uses triangulation would have offered a much higher granularity

    Technology, Policy, Growth - Theory, Evidence and Interpretation

    In recent years the research on the relation between technology and economic growth has flourished. This paper presents a brief overview of different theoretical perspectives in this area; the old orthodox theory (that of Robert Solow and others), more heterodox approaches, and the new orthodox theory (commonly labelled new growth theory). Furthermore, we assess the relationship between these theoretical approaches and applied work on growth and policy.

    Competitiveness, Scale and R&D

    The purpose of this study is to explore the relationship between competitiveness, scale and R&D with the held of OECD databases and the ongoing work in the OECD on embodied technology flows. The analysis is based on data for ten OECD counteies and 22 industries in 1985. The results suggest that both direct R&D and R&D acquired indirectly through purchase of capital goods and intermediates have a significant, positive impact on competitiveness. Indirrect R&D from domestic sources appears to be more conducive to competitiveness than indirect R&D from aboard. On average the total (direct and indirect) impact of a given investment in R&D on exports is about twice as large as the impact of an investment of similar size in physical capital. The impact of R&D investment appears to be especially high in large countries and R&D intensive industries.

    Innovation: A Guide to the Literature

    Innovation is not a new phenomenon. Arguably, it is as old as mankind itself. However, in spite of its obvious importance, innovation has not always got the scholarly attention it deserves. This is now rapidly changing, however. As shown in the paper, research on the role of innovation economic and social change has proliferated in recent years, particularly within the social sciences, and often with a bent towards cross-disciplinarity. It is argued that this reflects the fact that no single discipline deals with all aspects of innovation, and that in order to get a comprehensive overview of the role played by innovation in social and economic change, a cross-disciplinary perspective is a must. The purpose of the paper is to provide the reader with a guide to this rapidly expanding literature. In doing so it draws on larger collective effort financed by the European Commission (the TEARI project), one of the outputs of which will emerge as Oxford Handbook of Innovation, edited by Jan Fagerberg, David Mowery and Richard R. Nelson.

    Technology, Trade Structure and Economic Integration - An examination of Intra-Nordic, Nordic-EC and Intra-EC trade 1961-1987

    Get PDF
    This paper discusses the impact of economic integration on production and trade in high-tech goods. The theoretical evidence is considered in section 2. The remaining part of the paper presents an empirical analysis of this relationship for two groups of countries, the Nordic countries and the EC, between 1961 and 1987. A positive impact of integration on trade in high-tech goods may be found for the Nordic countries in 1960s and early 1970s. There is no evidence of a similar relationship for the EC. This supports the view that countries with small differences in culture and language are more likely than others to experience a positive impact of integration on trade and production in high-tech goods.

    Is there a large-country advantage in high-tech?

    High-tech is a commonly used catch-word for industries that use a relatively large share of their resources on R&D and develop many new products and processes. It is a widely held view that high- tech is good for growth, and that countries that succeed in high- tech industry perform well. Schumpeterian theory, as well as the more recent “new growth” theories, are often quoted in support of this view. However, the “new growth” theories also suggest that large countries are more likely than small ones to succeed in high-tech. This paper explores empirically the factors behind success or failure in high-tech industry for a sample of OECD countries from the 1960s to the 1980s. It is concluded that although there exists a group of high-tech industries for which the scale of the country seems to matter a lot, this does not extend to all industries where R&D and innovation are important. However, cost competition tends to be more severe in those industries where small countries can compete on equal terms. Thus, small countries do to some extent face a greater challenge in high-tech than large countries

    Europe at the Crossroads: The Challenge from Innovation-based Growth

    Get PDF
    Europe’s performance relative to the US and countries in Asia is a topic that greatly preoccupies policy-makers who are concerned that the EU is losing ground compared to other, more dynamic parts of the world. Although the recent crises in Asia gave a timely reminder that the grass often looks greener on the other side of the fence, this paper points to trends in EU performance that European policy-makers will find disconcerting. Productivity growth has slowed down relative to competitors. Export competitiveness has deteriorated in all areas except agriculture and raw materials. The losses have been most manifest in the technologically most sophisticated industries, particularly ICT. Europe has also failed to create employment on a scale at all comparable with the US or Japan, with obvious repercussions for unemployment. While until recently there was a tendency towards convergence in productivity and income between European regions, there are now signs of a reversal of this trend. Redressing this relatively disappointing performance will be neither easy nor quick, but if enduring answers to Europe’s problems are to be found, it is essential that the scale and nature of these problems are carefully diagnosed and solutions found. This paper argues that the problems that Europe faces in key areas such as growth, equality and employment are all related to its failure to take sufficient advantage of technological advances, particularly the ICT revolution. Consequently, a coherent European strategy for upgrading technological capability and quality competitiveness is long overdue. This cannot be limited to providing support to selected industries (or companies) in order to make them more competitive in global markets. Rather, what Europe has to do is to take steps to embed new technologies in society. This should bring together macro-economic policy, regulation, science and technology policy, and employment initiatives. The complementarities between policy areas, in particular, should be stressed.
