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
Leading by example: how National Sports Federations implement environmentally sustainable change through human resource management
No full textLeisure organisations have ecological footprints and are subject to external pressures of diverse nature to address their change processes towards environmental sustainability. In these paths, knowledge concerning the role of human resource in leisure organisations remains unresearched. Adopting institutional theory and change management literature, this study aims at understanding whether and how organisations address environmental change through human resource management, while uncovering the drivers and challenges of these attempts. Data generated through interviews with executives of national sport federations reveal that top-management ecological conscience, the recognition of leading groups or roles, training and socio-environmental pressures are recognised as drivers of environmental change implementation. On the contrary, a substantial lack of logistic autonomy, finances and scope-oriented recruitment appear to obstruct positive change. Importantly, this study highlights that in the presence of normative and coercive vacuity within the broader system of the organisations national federations adopt a proactive bottom-up approach with respect to environmental changes. Indeed, although embryonal, limited, self-managed and uncoordinated by a supervisor authority, environmental processes of national sport federations via human resource management are in motion, pointing towards a rather optimistic future for the progress of leisure organisations

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
