    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

    Does managerial capability always drive performance? Empirical examinations of small and medium firms (SMEs) in a developing economy

    Purpose The paper sought to uncover the conditions under which managerial capability enhances performance while considering the role of social capital within the unique boundary conditions created by competitive intensity. Design/methodology/approach The authors use multi-source data from 206 managers and owners of SMEs from a Sub-Saharan African nation – Ghana. Findings Using structural equation modeling (SEM) to analysis the data, the findings revealed that social capital serves as a mechanism through which managerial capability influences performance. Furthermore, the results indicate that competitive intensity does not significantly moderate this important indirect relationship. Implications: This study provides relevant knowledge for scholars, practitioners and policymakers on the role of managerial capability and how it may be harnessed in enhancing performance. Originality/value This paper provides a holistic understanding of the capability performance relationship in attempts at extending the literature by examining social capital as a mediator and competitive intensity as a contingent factor of this important relationship in a conditional indirect model

    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

    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

    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

    Social capital and performance of SMEs: The role of entrepreneurial orientation and managerial capability

    No full text
    This study proposes and investigates the argument that social capital–performance link is mediated by entrepreneurial orientation (EO) and that this mediated relationship is dependent upon the level of managerial capability (MC) present in a firm. The study uses a sample of 206 SMEs based in the sub-Saharan African economy. Mainly supporting conjectural predictions, the study indicates that EO intervenes the social capital (SC) effect on performance, with same effects uniquely strengthened according to the dimension of EO in question at higher levels of MC. The study expands our understanding of how the umpiring role of EO in the SC–performance link is contingent upon levels of MC present. Managers are, therefore, encouraged to strategically develop both EO and MC to enable them to effectively utilize and profit from the benefits SC has to offer
