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
Impact of social capital evolution on family business value creation during transmission period
No full textL’importance de l’entreprise familiale (EF) et la légitimité de ce champ de recherche ne sont plus à démontrer. L’EF est une forme dominante dans plusieurs tissus économiques, dont celui de la Tunisie. La succession de l’EF a constitué un axe majeur de recherche dans ce champ. La transmission implique à la fois des enjeux économiques et sociaux inhérents à la survie de l’EF aux générations suivantes. Durant la dernière décennie, une série conséquente de travaux s’est intéressée à l’étude de l’EF et de sa transmission suivant l’approche par les ressources (Salvato et Melin, 2008 ; Sirmon et Hitt, 2003 ; Cabrera-Suarez et al, 2001). L’identification des ressources cruciales pour ce type d’entreprise, et la transmission de ces ressources constituent deux questions fondamentales pour cet axe de recherche. Le capital social, en tant que ressource caractérisant l’imbrication de la sphère familiale avec celle des affaires, a été identifiée comme ressource cruciale de l’EF (Pearson et al, 2008 ; Arrègle et al, 2007). Le capital social de l’EF se caractériserait par une certaine stabilité, liée à la longévité du fondateur, mais accuserait, également, un moment critique lors de l’entrée du successeur. Cette recherche se propose d’enrichir la compréhension de la phase de transmission en s’intéressant à l’évolution du capital social intra-organisationnel de l’EF, suite à l’entrée du successeur. Notre étude s’inscrit dans la continuité des travaux mobilisant la théorie de Nahapiet et Ghoshal (1998). Cette théorie avance que le capital social est une ressource déterminante de la création de valeur des organisations. Notre recherche ambitionne d’explorer l’évolution de la relation entre le capital social de l’EF et sa création de valeur, suite à l’entrée du successeur. Nous avons mené une étude longitudinale, sur une période de 18 mois, auprès de quatre EF où le successeur a récemment rejoint l’entreprise. Deux groupes de cas sont identifiés suivant le niveau de création de valeur de l’EF. Le premier groupe a révélé des évolutions remarquables au niveau des dimensions structurelle et cognitive du capital social. L’évolution de la création de valeur dans les deux cas de ce groupe s’est manifestée à travers des innovations produits, des innovations organisationnelles et de nouveaux choix stratégiques. Le deuxième groupe a révélé une évolution moins remarquable de la dimension structurelle du capital social et une certaine stabilité des dimensions relationnelle et cognitive. L’évolution de la création de valeur a été timide dans les deux cas de ce groupe. Nos observations confortent certaines propositions théoriques avancées par Nahapiet et Ghoshal (1998) sur la relation entre le capital social et la création de valeur. Nos résultats révèlent, également, que l’évolution du capital social engendrerait de nouveaux choix stratégiques dans certains cas.The legitimacy and the importance of family business (FB) research have become obvious. FB is a dominating form in many countries, including Tunisia. Among the different family business trends, FB transmission constitutes the most important research field. FB transmission and survival involves economic and social challenges for the family, the society and the entire economy. Since the last decade, a bundle of studies mobilized the Resource Based View for FB and transmission research (Salvato & Melin, 2008; Sirmon & Hitt, 2003; Cabrera-Suarez & al, 2001). Two main questions constituted the background of those studies: Which resources are supporting the FB competitive advantages? And, how those resources are transmitted to preserve FB sustainability? Social Capital was considered as crucial resource for FB (Pearson et al, 2008; Arrègle et al, 2007). According to those authors, social capital is a resource formed and shaped by the overlap of the family and the business spheres. Since FB is governed by the founder during a long period, its social capital would be characterized by some stability. However, the successor’s entry is a critical moment for this social capital as well as the FB. Our research aims at enhancing our understanding of the FB transmission through observing the social capital evolution after the successor’s entry. Our study is based on the social capital theory suggested by Nahapiet & Ghoshal (1998). This theory assumes that social capital is a crucial resource for organization value creation. Our study explores the evolution between social capital and FB value creation after the successor’s entry. Four longitudinal case studies were performed, during 18 months, on FBs where the successor recently joined the company. Our evidence reveals a social capital evolution for each case. According to the value creation evolution, two subgroups are identified. The first group revealed remarkable evolutions of the structural and cognitive dimensions of social capital. The value creation evolution in this group of two cases concerns product innovation, organizational innovation and new strategic choices. However, the second group revealed less important evolution in the structural dimension of social capital. The cognitive and relational dimensions of social capital were quite steady and the value creation evolution was limited in this second group of two cases. These findings confirm some theoretical propositions suggested by Nahapiet & Ghoshal (1998) regarding the relation between social capital and value creation. Moreover, these results suggest that social capital evolution would entail new strategic choices and innovations

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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
