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
Un Essai Sur Les Déterminants de La Croissance Economique Et de L’Epargne à Madagascar
No full textRESUME Cette étude essaie d’apporter des éléments de réponses en ce qui concerne les analyses à l’endroit de l’origine de la situation économique morose et chronique malagasy. En effet, il a été détaillé dans cette recherche la cause de la succession de la fluctuation conjoncturelle du PIB malagasy ainsi que sa capacité à atteindre la tendance séculaire et les politiques économiques entreprises depuis les années d’indépendance du pays. Mais quelle politique économique faut-il adopter pour amplifier les impulsions de croissance tant attendues par le pays depuis les années ’60 ? Ce travail de recherche essaie donc de déterminer les variables macroéconomiques qui sont susceptible d’amorcer la croissance économique du pays et de formuler des politiques économiques qui sont capable de se cadrer aux variables clés de la situation ainsi détectée.Des analyses économétriques ont été indispensables par rapport aux objectifs qu’on a formulés en supra. Ainsi, la croissance économique de Madagascar est déterminée de façon structurelle par le revenu initial, l’investissement global, et l’ouverture économique. C’est pour dire que l’augmentation à long terme de ces grandeurs contribue positivement à la croissance économique du pays. Nous avons également d’autres variables très significatives mais qui ont des influences négatives sur la croissance économique du pays sur une longue période si on ne cite que la variable de la démocratie et l’espérance de vie de la population. L’inflation n’est significative qu’au seuil de 14%. Pour une analyse conjoncturelle, ses déterminants restent les mêmes sauf pour l’inflation qui est devenu significative sur une observation de courte période.A titre de recommandations, deux différents horizons temporels seront à déceler : Pour une politique à court terme, il serait nécessaire d’opérer sur une politique axée sur l’ouverture du pays avec le reste du monde en termes d’échanges internationaux plus intenses, vu l’importance que porte le coefficient donné par le modèle pour cette variable à côté de l’investissement. Il faudrait exporter davantage et importer, en contrepartie, des équipements nécessaires à la production nationale. Une politique d’investissement de long terme devrait également être mise en œuvre avec une politique de renforcement de l’ouverture de l’économie nationale sur le marché extérieur.ABSTRACTThis study is an attempt to provide some answers regarding the analyze of the gloomy and chronic origin of the Malagasy economic situation. Indeed, the policies that shaped the causes of the succession of the cyclical fluctuation of the Malagasy GDP as well as its capacity to reach the secular trend from the independence of Madagascar are detailed in this work. But what economic policy should be adopted to amplify the expected growth stimulus from 1960s? This study therefore tries to determine the macroeconomic variables which are likely to initiate the economic growth of the country and to formulate economic policies which are capable of fitting in with the key variables of the situation thus detected.Econometric analyzes are crucial in relation to the objectives formulated above. Thus, Madagascar’s economic growth is structurally determined by Initial Income, Global Investment, and Economic Openness. This is to say that the long-term increase in these quantities contributes positively to the economic growth of the country. We also have other variables which are very significant but which have negative influences on the economic growth of the country over a long period if we only quote the variable of democracy and the life expectancy of the population. Inflation is only significant at the 14% threshold. For a cyclical analysis, its determinants remain the same except for inflation which has become significant over a short period of observation.As recommendations, two different time horizons will be identified: For a short-term policy, it would be necessary to operate on a policy focused on opening up the country with the rest of the world in terms of more intense international trade, given the importance of the coefficient given by the model for this variable alongside investment. We should export more and import, in return the necessary equipment for national production. A long-term investment policy should also be implemented to the external market with a strengthened and opened national economy policy.
Impacts Des Chocs Macroéconomiques Sur La Capitalisation Des Banques Individuelles A Madagascar
No full textRESUMELes crises financières, qui se sont succédées, ont mis en exergue l’interdépendance entre le système financier et l’économie réelle. Les mesures prudentielles, pour limiter les répercussions néfastes de la crise financière, à travers les accords de Bâle I et Bâle II ont montré leurs limites et les accords de Bâle III ont intégré en conséquence le volet macro-prudentiel qui vise à assurer la stabilité du secteur financier dans son ensemble au sein de l’économie. L’outil d’évaluation de la stabilité financière sous le nom de « stress test » s’est également développé sous différentes formes et son application au niveau du secteur financier, notamment le secteur bancaire, est fortement recommandé par la Banque des Règlements Internationaux. En effet, l’objet de la présente étude consiste à évaluer la résilience du secteur bancaire malgache face aux chocs macroéconomiques et d'évaluer son impact sur la capitalisation du système bancaire à travers l’outil de stress test macroéconomique. Pour ce faire, notre avons recouru à un modèle de panel dynamique Les prévisions des prêts non performants sont utilisées pour obtenir des projections des capitaux propres à la fois au niveau du système bancaire et au niveau des banques lors des scénarios défavorables. Les résultats montrent que la plupart des banques ont pu détenir des fonds propres supérieurs au seuil minimum réglementaire de 8% selon les normes de Bâle III. Toutefois, une seule banque n’arrive pas à respecter le seuil minimum d’adéquation de capitaux propres. Mots clés : Stabilité financière, stress test, capitalisation, secteur bancaireABSTRACT The successive financial crises have highlighted the interdependence between the financial system and the real economy. Prudential measures to limit the negative repercussions of the financial crisis, through the Basel I and Basel II agreements, have shown their limits and the Basel III agreements have consequently integrated the macro-prudential component which aims to ensure the stability of the financial sector as a whole within the economy. The financial stability assessment tool known as the "stress test" has also been developed in various forms and its application to the financial sector, particularly the banking sector, is strongly recommended by the Bank for International Settlements. Indeed, the purpose of this study is to assess the resilience of the Malagasy banking sector to macroeconomic shocks and to evaluate its impact on the capitalization of the banking system through the macroeconomic stress test tool. To do so, we used a dynamic panel model. Non-performing loan forecasts are used to obtain capital projections at both the banking system and bank levels under adverse scenarios. The results show that most banks were able to hold capital above the minimum regulatory threshold of 8% under Basel III standards. However, only one bank fails to meet the minimum capital adequacy threshold.Keywords: Financial stability, stress test, capitalization, banking secto
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
