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
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
Information sectorielle : quelle place dans les rapports des analystes financiers ? Une étude empirique du secteur hôtelier international
No full textInternational audienceWe address whether financial analysts dealing with international hotel groups reporting under SFAS 131 and IAS 14 refer to segment information and use segmental models in their recommendation reports. Although the analysts' forecasts through consensus are frequently analyzed, research does not often focus on the real contents of their reports. Through the reports of analysts on international hotel groups published in 2006, we picked out the references to voluntary and compulsory segment information. We also determined whether financial analysts present segmental models of forecast or valuation in their recommendation reports. We found that financial analysts widely refer to voluntary and compulsory segment information, especially to geographic segment information when reported. Segmental models of forecast or valuation are sometimes presented; mainly with LOB segmentation. Whether segmental information balances with financial choices will be confirmed by further research. The convergence between the American and international standards could impact financial analysts' models.Notre recherche propose d'identifier comment les analystes se réfèrent à l'information sectorielle publiée par les groupes et quelle place occupe l'information sectorielle dans leurs modèles financiers. Nombreuses sont les recherches qui se fondent sur l'analyse des consensus, peu s'intéressent au contenu réel des rapports réalisés par les analystes. Nous avons déterminé les références faites à l'information sectorielle tant obligatoire que volontaire au sein des rapports rédigés en 2006 par les analystes financiers des groupes hôteliers internationaux publiant selon la norme SFAS 131 et IAS 14. Nous avons aussi observé si les rapports des analystes financiers présentaient des modèles de prévisions ou de valorisations construits selon une base sectorielle. Nos résultats montrent que les analystes financiers se réfèrent très massivement à l'information sectorielle, qu'il s'agisse de l'information normalisée ou d'une information volontaire. Plus spécifiquement, si elle est disponible, l'information géographique sectorielle est très souvent utilisée. Toutefois, l'approche sectorielle demeure occasionnelle dans les modèles utilisés pour argumenter les prévisions ou les valorisations ; l'approche selon les « secteurs d'activité » étant alors privilégiée. La pertinence des résultats obtenus d'après une approche sectorielle dans les modèles financiers pourra faire l'objet d'une recherche future. La récente adoption de la norme IFRS 8, convergence des référentiels IFRS et US GAAP, pourrait bien aussi impacter les outils de modélisation utilisés par les analystes
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
Corporate Reporting and the Eco-Consciousness: Some Preliminary Evidence from Italian and French Practices
No full textThis chapter deals with the sensibility of selected Italian and French listed corporations towards climate change issues and related disclosure in the light of the recent transposition of Directive 95/2014 into the respective legislations. Af-ter briefly reviewing the path which has brought to the aforementioned directive and how Italy and France have transposed its contents, 8 firms (4 for each coun-try) belonging to the most representative and comparable sectors of the two countries have been selected. Then, selected features related to their Non-Financial Information dealing with climate change aspects have been analyzed using the method of content analysis. The results of this effort is an unweighted climate-related disclosure index, which allows us to resume the state of the art of firms’ eco-consciousness individually, at country level and in comparative terms. Evidence achieved suggest that the directive and its transposition have fostered higher attention to climate change aspects, especially in country with a poor tradition in disclosing Non-Financial Information like Italy. On the other hand, the flexibility agreed by Directive and respective laws rise up questions re-garding whether, to what extent and where information have to be disclosed in order to make possible effective comparisons. At last, the lack, until now, of any attempt to translate in monetary terms effects of climate-related behaviors and actions draws out doubts regarding the consistency of the overall efforts actors involved are spending to enhance the sensibility toward climate change and envi-ronmental issues
