Data centres between North-South and East-West
No full textAs recently as 2014, The Hindu Business Line reported that India was unlikely to emerge as a global Data Centre hub. Citing factors such as outdated telecom policies and rolling power cuts, the newspaper noted that smaller rivals such as Singapore, Hong Kong, and Taiwan had outperformed India in this key sector of digital economy (Charlie 2014). Five years later, an industry report by consultancy firm Broad Group (2019) indicated that India is the world's second largest growing Data Centre market in Asia, after China. According to this report, 70 per cent of India's data is still stored beyond its shores, but new data localisation legislation means that growth with proceed rapidly, particularly in cities such as Mumbai, Chennai, Hyderabad, and Bengaluru. The significance of the Broad Group report lies less in its boosterism, which serves the Data Centre industry's search for new frontiers, than in its registration of the changing global geography of Data Centre location. One of the most important contributions of the chapters that make up this volume, which examines the past and present of Data Centres in India, is to take stock of this changing geography. Existing critical work on these facilities tends to focus on infrastructures located in the global North (see, for instance, Hogan and Vonderau 2019). By giving due attention to the conditions of emergence and operations of Data Centres in one of the world's most prominent rising markets for these infrastructures, the chapters in this book begin to ask how Data Centres contribut to the production of geographical and economic conditions that shift the axes of global power. In this way, the volume adapts the argument that 'postcolonial capitalism' is a global condition (Mitra et al. 2017) to the new modes of governance made possible by digital technologies
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
