    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

    Second Life Batteries: Current Regulatory Framework, Evaluation Methods, and Economic Assessment: Reuse, refurbish, or recycle

    Given the strong penetration of electric vehicles (EVs) and renewable energy sources, battery demand is dramatically increasing. To satisfy this huge request for batteries, a possible solution, taking into account a circular-economy framework, is given by second-life batteries (SLBs), a new technology that exploits deteriorated batteries from the EV sector for less demanding applications, such as stationary storage. On the one hand, SLBs make it possible to use batteries to their full extent. On the other hand, specific standards for SLBs are still missing and, from an industrial point of view, there are several factors that influence whether this business would be convenient or not. This article presents a possible lifecycle for EV batteries where SLBs are considered with different business strategies, also taking into account the possible SLB applications that can be derived from the reuse of batteries before being recycled. From an economic point of view, an economic assessment is introduced, providing possible parameters that may affect the SLB business either positively or negatively

    Appropriate Similarity Measures for Author Cocitation Analysis

    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

    Second Life Batteries: Current Regulatory Framework, Evaluation Methods, and Economic Assessment

    No full text
    In this article, second-life batteries (SLBs) are presented and discussed in their full context. Market forecasts, applications, the current regulatory framework, state-of-the-art SLB technologies, the value chain, and a benchmark analysis of the main SLB players are illustrated and discussed, together with a practical economic assessment. The second life battery market is still nascent, therefore many normative blind spots still need clarifications. The lack of specific standards related to SLB is a significant limitation for the analysis of the economic viability of a Second Life Battery Energy Storage System (SLBESS). Moreover, there is no evident gold standard for an efficient industrial model concerning applied technologies and testing procedures necessary for second life application deployment. This work tackles these aspects at all levels and eviscerates them to present possible coherent solutions if present

    Dispelling the Myths Behind First-author Citation Counts

    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

    We 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
