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
Withanolide composition and in vitro culture of Italian Withania somnifera
No full textFrom Italian plants of Withania somnifera six withanolides were isolated, whose structures allowed us to assign the Italian race of W. somnifera to the Israel chemotype III. In vitro cultures of Italian W. somnifera under different conditions were obtained, as well as infection by Agrobacterium rhizogenes. HPLC analysis of in vitro derived tissues showed low contents of withanolides
Industry and academia for a transition towards sustainability: advancing sustainability science through university-business collaborations
No full textThis paper gathers evidence from the current crisis in sustainability, which indeed has led to unsustainable global, social and human systems, to reaffirm the increasing importance of the business sector, not only in terms of its central role in the achievement of the current unsustainable path, but above all the role still to be played by business in the transition towards sustainability. Principally, this review focuses on the concept of business sustainability and calls for the necessity of collaboration between industry and academia within the context of sustainability science. To provide a reasoned and robust argument, the main co-operation modalities and best practice currently applied out of the sustainability science paradigm are reviewed. Furthermore, collaborations between industry and academia experienced within the framework of International Conferences on Sustainability Science (ICSS) are analyzed, by describing the founding principles of the innovative scientific paradigm, its evolution and its application to the field. In addition, the manuscript stresses the current relevance of the sustainability science discipline while attempting to institutionalize a collaborative and participative process, and confronts the expected outcomes with the obstacles faced. Finally, the paper proposes a series of recommendations for conducting successful business–academic collaborations within the framework of sustainability science
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
‘She askes of him the gift of prophecie’. La Cassandra elisabettiana di Richard Barnfield
No full textQuesto contributo si concentra su un trascurato rifacimento early modern del mito di Cassandra: The Legend of Cassandra di Richard Barnfield. L’analisi di questo eccentrico epillio elisabettiano mostrerà le strategie impiegate da Barnfield per ritrarre e ri-semantizzare il personaggio di Cassandra. Saranno messe in evidenza le insolite scelte stilistiche fatte da Barnfield nella Legend, in cui convivono, insieme agli stilemi dell’epica minore diffusissima al tempo, anche quelli più moraleggianti tipici dei lamenti e quelli celebrativi dei panegirici. Si dimostrerà come questa insolita commistione dia prova della grande abilità del poeta nell’aggirare i rischi di possibili associazioni tra un personaggio dalla fama ambigua come Cassandra e la protagonista femminile (più o meno esplicita) di molte opere poetiche di quegli anni: la regina Elisabetta I
