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

No full textCompetence management plays a pivotal role in enhancing the competitiveness of organizations in today's fast-changing business environment. In particular, the use of ontologies for the structured management of competence data has proven to be strategic in various industries (such as, manufacturing, aviation and construction) and for different industrial processes (from supply chain management to product lifecycle management). However, despite their demonstrated utility, there remains a significant gap in the literature regarding the specific implications of employing ontologies for competence management in industrial contexts. Hence, the primary objective of this study is to investigate the implications of employing ontologies for competence management in industrial settings. By conducting a Systematic Literature Review (SLR) and bibliometric analysis about this topic, we aim to shed light on the intricacies of utilizing ontologies in managing competence and identify key areas for future research. The conducted keyword co-occurrence analysis identifies six thematic clusters: "Knowledge Representation of Manufacturing Processes"; "Education for Software Engineering"; "Semantic Technologies for Decision Making"; "AI for Knowledge Management", "Ontologies for Human Resource Management (HRM)" and "Competence Management for Industrial Innovation". From an academic perspective, this paper provides an overview of the implication of ontologies in industrial competence management underscoring the importance of ontologies in structuring competence- related information, facilitating decision-making processes and promoting innovation within organizations. Moreover, the study reveals a growing trend of research in this area, with emerging trends reflecting the integration of ontologies with advanced technologies, such as artificial intelligence and machine learning, which would enable organizations to rapidly adapt to changes in today's industrial environment. From a managerial perspective, instead, the study offers insights into best practices and challenges associated with the adoption of ontologies, guiding strategic decisions toward future trends and innovations in competence management
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
