    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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

    A Survey on Microservices Security: Preliminary Findings

    No full text
    Microservices have become the state-of-the-art architectural style for distributed systems, however we notice the lack of comprehensive guidelines on Microservices Security. Motivated by this observation, we started an ongoing work to categorise the literature on Microservices Security, with the intent to overview the current status of the field, to provide an initial guideline to researchers and practitioners, and to possibly identify uncovered areas and orient future research. In our presentation at Microservices 2020, we propose to present the state of the art and discuss some of the most interesting insights we collected so far, such as: main security attacks occurred, the relation between software development and security, the main technologies involved, and the main application domains

    TechNETium: Atomic Predicates and Model Driven Development to Verify Security Network Policies

    Fifth-generation (5G) networks will deliver unprecedented levels of quality of service for online gaming and multimedia-rich social interaction, providing virtual environments optimized for vertical applications through innovative approaches to physical resource management. These techniques must consider security aspects in all phases and at every layer. Trusted communications between individuals and reliable platforms running services for social good depend on the resiliency to network-level attacks such as hijacking and denial-of-service. The verification of topological properties represents a well-suited approach to address these issues in a 5G environment. This paper illustrates moves from formal methods existing in literature, namely atomic predicates (AP) and header space analysis (HSA). It describes a method of integrating AP in Software Defined Network architectures, achieving the same expressive power as HSA without its performance hit, to make topology verification viable for real-time security applications

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We 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
