    Innovation systems and policy in a global economy.

    No full text
    New technologies are a fundamental part of modern economic life. Economists and engineers, no less than politicians and public opinion, are devoting increasing attention to understanding why, how and where technological innovations are generated. This book is devoted to discussing two separate, but closely connected bodies of literature on the sources and nature of new technologies. The first set is focused on the similarities and differences in the organisation of innovative activities at the national level, whilst the second group is centred on the role of globalisation in shaping technological change

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Regulation of sovereign wealth funds

    This thesis analyses the motivations, behaviours and outcomes of Sovereign Wealth Funds (SWFs), and the regulations pertaining to them. The motivation for examining these issues includes the growing role of SWFs as large investors in a wide range of global asset classes, their continued resistance to transparency, and the perceived lack of any unified regulatory framework to cover their activities. We consider the evolving attitudes amongst regulators, SWF officials, and independent analysts and commentators to the current and evolving regulatory environment for SWFs. Regulatory approaches include both mandatory and voluntary measures. Following a review of both the academic literature and other available materials on SWFs, we consider what type of regulation would seem both appropriate and proportionate for SWFs, and we evaluate the significance of the fact that although SWFs operate within frameworks similar to other alternative investment funds, their culture is inherently different. We conducted fourty-three in-depth interviews, and compared and contrasted the various opinions regarding the current and evolving operation and regulation of SWFs. We followed these up with two country case studies, for Russia and China respectively. For these, we set out the background to their respective SWFs, and discuss the current and evolving state of their investment strategies and of the regulatory environments in which they operate. We consider in particular the extent to which SWFs may be pursuing geopolitical agendas, and on the other hand the degree to which they may be potential contributors to the public good, for example as a stabilising factor during global financial crises. We thus consider the impact on global markets of their investments â and the implications of the degree of transparency and accountability within which they tend to operate; and we explore the case for additional regulation of these entities. We conclude, firstly, that greater visibility and control of SWFs would be desirable; and secondly, that a range of regulatory approaches and policies might prove appropriate in dealing with what are often rather different SWFs, often reflecting the outlook of their parent state. Thus, the Norwegian SWFs (Government Pension Fund Norway, and the Oil Fund) reflect the transparency favoured by that state; the Russian National Wealth Fund reflects the preference for secrecy inherent in the Russian state; while the activities of the China Investment Corporation match the breadth and high profile favoured by the Chinese state, albeit restricted by the controlling tendencies of the Chinese government.</p
