Boundary Images
No full textHow are images made, and how should we understand the capacities of digital images? This book investigates images as well as the technologies that host them. Its three chapters discuss the boundaries that images cross and blur between humans, machines, and nature and the ways in which images are political, material, and visual. Exploring these boundaries of images, this book places itself at the limits of the visual and beyond what can be seen, understanding these as starting points for the production of new and radically different ways of knowing about the world and its becomings.Published versio
Algorithmic Authenticity: An Overview
Full text linkWhat makes information feel true or compelling in our contemporary digital societies? This book brings together different disciplinary understandings of "authenticity" in order to find alternative ways to approach mis- and disinformation that go beyond contemporary fact-checking and its search for the "authentic" truth. Patterned under the algorithmic flows of digital capitalism, authenticity itself is subject to variation, iteration, and outside influence. Linking cross-disciplinary research on the history and practices of algorithmic authenticity points to new research questions to understand the impact of algorithmic authenticity on social life and its role in contemporary information disorder
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
Far-Right Recruitment and Mobilization on Facebook:The Case of Australia
No full textThe Internet is a powerful tool for the far right.1 By facilitating communication and participation across spatial boundaries, connecting like-minded organizations and spreading their messages (Caiani and Parenti 2016), the Internet, and in particular social networking platforms, have become vital to recruitment and mobilization for the far right today. This is especially the case in contexts where the far right faces institutional or social marginalization. This chapter explores how the far right utilizes the popular social networking platform Facebook through a case study of the Australian far-right Facebook fan page network in 2018. Though significant research has been conducted on the use of social media by the far right (e.g. Engesser et al. 2016; Ernst et al. 2016; Froio and Ganesh 2019; Klein and Muis 2019), these have tended to focus on the discursive or communicative utility of such platforms
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
