Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Quatre essais sur l'appariement des entrepreneurs et des investisseurs en capital risque européens
No full textNotre recherche vise à établir un cadre pour améliorer la compréhension du marché de capital-risque européen et l’appariement entre entrepreneurs et fonds de capital risque qui a lieu dans ce marché. Nous présentons quatre essais qui permettent de connaître: la littérature théorique et empirique sur le domaine, les différents types des Fonds de Capital Risque qui participent au financement des entreprises en phase de démarrage et les dimensions qui comptent le plus dans les relations entre ces participants.Our thesis aims to improve the understanding of European Venture Capital market and the matching that takes place between entrepreneurs and Venture Capitalists. We present four essays that allow us to get to know: the theoretical and empirical literature on the subject, the different types of European venture capitalists participating in the financing of early stage ventures and the dimensions that count in this relationship
Firms and environmental management : management practices in risky sites located on the french coast
No full textFace à une montée en puissance de la conscience sociétale et au renforcement législatif,les questions environnementales représentent un enjeu stratégique pour les établissements polluants.Inscrite dans le champ de la RSE,cette thèse vise à comprendre la décision de gestion des risques environnementaux au sein d'établissements à risques situés dans des agglomérations littorales françaises.Elle analyse les dispositifs d'évaluation, de gestion et de communication des risques environnementaux, appelés «risques industrialo-environnementaux» (RIE),et identifie les motivations et freins de ces actions tels qu'ils sont perçus par les responsables.Les travaux sur la décision individuelle face au risque,la théorie des parties prenantes,et la théorie néo-institutionnelle servent de prisme théorique.La méthodologie s'articule en deux temps:19 entretiens avec analyse textuelle,et 196 questionnaires.Malgré une prise de conscience collective des enjeux environnementaux,les RIE sont gérés significativement depuis une dizaine d'années.Si la réglementation et les valeurs des dirigeants guident principalement les établissements vers une gestion plus responsable,la complexité des textes réglementaires et le manque d'informations expliquent la perte de vitesse des initiatives environnementales (SME, EMAS, partenariats). Les établissements sondés adoptent des démarches réactives de conformité réglementaire.Les coûts,le manque de moyens,la faible perception des avantages immédiats sont des freins à la poursuite d'actions environnementales plus ambitieuses.La gestion des RIE apparaît davantage comme un moyen onéreux de légitimer et de pérenniser les activités que comme une opportunité économique.The increasing societal awareness and the intensification of the regulation make henceforth strategic environmental issues for pollutant sites. Included within the scope of the CSR, this thesis aims to understand the management decision of environmental risks within risky sites located in French densely populated coastal areas. It analyses the ways of evaluating, managing and communicating about environmental risks, also called “industrialo-environmental risks” (IER), and identifies motivations and difficulties of these actions as described by managers. The research is based on a multidisciplinary theoretical framework: the work on the individual decision under risk, the stakeholder theory, and the neo-institutionalism. The research methodology is divided into two times: a qualitative study of 19 interviews with textual analysis, and a survey of 196 sites by questionnaire. Results emphasize that, despite a collective awareness of environmental issues, IER have been significantly managed since only a decade. If regulatory stakeholders and leaders' values primarily guide risky sites towards a more "responsible" management, the complexity of regulation and the lack of information explain the slowing of environmental initiatives (EMS, EMAS eco-audit, partnerships). The surveyed sites adopt reactive approaches of regulatory compliance. Costs, lack of human and financial resources, and the low perception of the immediate benefits are considered as barriers to the pursuit of more ambitious environmental activities. Thus, the IER management appears more as a way to legitimize and sustain activities as an economic advantage
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
