Cities between digital innovation and platform labour
No full textIn this final section we will consider the impact of digital technologies on urban spaces.On one side, this means how high tech giants and platform firms are establishing in urbanspaces as infrastructures for data accumulation and services’ development, influencingnot only urban planning but also economic and social fabric. On the other side, severalurban actors —from municipalities to dwellers— move towards entrepreneurialism oftenusing platforms and data. These processes pose new challenges to local governance interms of regulation and participation that we are going to explore in this paper.In the first paragraph, we will frame the relationship between urban spaces and digitaltechnologies referring to the concept of smart city. In the second, we will focus on aspecific subjectivity emerging in such background, the so-called urban entrepreneur. Inthe third, we will sketch challenges and potentialities for local governance in regulatingsuch phenomena

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
What is a tech worker, really?: On the meanings and meaning-making of a term
Full text linkIn recent decades, a myriad of occupational terminologies has been proposed to grasp the fast-changing labour arrangements in the digital economy. ‘Tech worker’ is among the more recent terms, mostly referring to white-collar employees in tech firms like Google or Amazon. This term was popularised by unionisation drives of high-paid workers in the IT industry, where the notion of the term was gradually expanded. This article reconstructs the use and meaning of the term and reflects on its divergent use in labour movements and academia. Based on this analysis, I argue for an understanding of ‘tech worker’ among researchers that acknowledges its political dimension and dynamic meaning-making
