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
Do the Media Refuse Refused Knowledge?
Full text linkThis chapter examines trends in the coverage and framing of the reporting of refused knowledge across Italian mainstream newspapers. Taking into consideration the media are relevant for the analysis of RKCs, firstly given RKC followers’ beliefs that media outlets are to be considered the ‘in-house organs’ of the scientific elites, and as such an inherently untrustworthy source of information. This chapter will enquire into media treatment of refused knowledge, in eight major Italian newspapers, with a view of analysing the extent to which the media address and/or reject refused knowledge attributable to the four RKCs examined in this volume. The focus is on the issues advocated by four RKCs concerned in two interconnected ways: a quantitative presentation of coverage through a longitudinal analysis, highlighting an agenda-cutting process, and a qualitative account produced by means of content analysis addressing the issue of the institutionalisation of scientific knowledge through the delegitimation of RKC claims. This content analysis enables us to consider the framing of the coverage and whether it reinforces science or opens up to public questioning of scientific knowledge. The chapter concludes by providing a balanced view of the institutionalisation-discreditation dichotomy as the output of the media representation of refused knowledge
Embracing refused knowledge: The turning processes
No full textThis open access book explores contemporary practices that challenge science, arguing that this matter cannot be simply disregarded as a new manifestation of “anti-scientism”. It scrutinizes the processes through which knowledge claims, refused by established institutions and the scientific community, seek legitimacy. Assuming an agnostic analytical stance, it explores the actors involved in such processes and their social worlds, their interactions with epistemic institutions, and the ways in which they enact such refused knowledge in their daily lives. Drawing on a three-year mixed-method research project, this collection demonstrates how refused knowledge can be seen as a distinct mode of knowing, employed in response to the uncertainties of everyday life. Thus, it offers a deeper understanding not only of how refused knowledge garners credibility, but also of how knowledge at large – including scientific knowledge – emerges from specific sociotechnical assemblages. The third chapter by Paolo Volonté highlights how endorsing and embracing a body of refused knowledge is much more than a merely cognitive act. Indeed, refused knowledge enacts the shaping of communities of people engaged in a contentious relationship with science, thus involving interpersonal bonds, networks and social relations that exceed mere instrumental objectives and shape a feeling of belonging. Belonging to a refused knowledge community is a milestone in a personal biography that often involves costs or, in any event, important changes in work and social relations, political choices, health choices and body care practices, etc. It is, therefore, not simply a cognitive, but also an emotional, material, behavioural and social transition enacting collective identities
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
