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
Facets of the Digital Work Debate: Challenges for a critical theory of informational capitalism
No full textThis article introduces the reader to the so called ‘digital labor debate’ in the context of the political economy of (new) media and (digital) communication. The political economy of social media is best qualified as surveillance-driven production of culture and as an interplay between distinct modes of production (commons based peer production and commodity production). The latter gives rise to the problem of how to understand the interplay between these modes. The article discusses contributions from different theoretical angels, such as the materialist theory of communication, the theory of cognitive capitalism, the theory of prosumption, and the theory of rent in the informational age. The discussion is organized by three topics: Does the use of social media qualify as work? Are users subsumed to capital control? Are users exploited? The article marks theoretical challenges for a critical theory of informational capitalism.This article introduces the reader to the so called ‘digital labor debate’ in the context of the political economy of (new) media and (digital) communication.

Communicative Activity: Social Theoretical Foundations for Critical Materialist Media and Communication Sociology in the Digital Age
Full text linkThis paper contributes to the social theoretical foundations of a sociology of media and communication by making use of the cultural–historical school in psychology. Such perspective gains relevance in digital capitalism and the blurring of production and Internet usage. The paper first revisits Habermas’s influential notion of communicative action and agency. Second, it uses activity theory as an alternative, more promising way of theorising because it links communication closer to work. A model of communicative action is introduced and a conceptual link between media and human tool use is established. Third, the paper elaborates on the notion of activity in the digital world and posits that digitalisation can be understood as a ‘machinisation’ of mental and communicative-coordinative work. The developed perspective, the paper concludes, allows critical media and communication sociology to operate with meaningful concepts of communicative expropriation, exploitation and alienation
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Digital Transformations and the Ideological Formation of the Public Sphere: Hegemonic, Populist, or Popular Communication?
Full text linkThis paper elaborates on a theory of the ideological public sphere in the age of digital media. It describes the public sphere as an initially ascending and then descending communication process that includes both polarising and integrating publics, which are organised by antagonistic media and compromise-building mass media. This framework allows us to distinguish between hegemonic, populist, and popular-oriented flows of communication, as well as register changes in the interplay of different publics driven by digital media platforms. Digital transformations of the public sphere give rise to antagonistic and networked-individualistic flows of populist communication that put public hegemony under constant pressure. The challenge is to find ways to strengthen popular communications that enable democratic learning processes and the flourishing of communicative competences of all citizens
