No full textThe article advances the hypothesis that cybersecurity policies can be conceived in terms of constituent policies. This analytical perspective, starting from the contributions of Lawrence Lessig and Theodore Lowi, appears to be particularly fruitful for the understanding of cyber security policies. The case study chosen is that of the United States. The analysis focuses on the dimension of the network architectures and on the policy choices prevailing in the different phases of development of cyber security policies: from the origins to George W. Bush, up to the experience of Barack Obama and the focus on the presidencies of Donald Trump and Joe Biden that allows us to highlight precisely a line of continuity that can be found in cybersecurity strategies and policies
Cybersecurity Politics and Policies: Actors, Strategies and Challenges
No full textThis introduction highlights the reasons and opportunities why a policy approach to
the study of cybersecurity is appropriate and summarises the contributions in the spe-
cial issue. The common thread linking all the articles is the institutionalisation pro-
cesses of cybersecurity policy, a perspective which makes it possible to analyse actors,
values, activities, national and supranational trajctories, and connects the interventions
with other policy domains. The article allows the editors of the special issue to delve
into some of the characteristic themes of the cybersecurity debate, and in particular
those of governance dynamics, awareness development, and the toolbox characteristic
of this field. Some proposals for future research are outlined at the end of the contributio
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
