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
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
Romanian banking competition. A new structural approach
Get PDFIn this work, we evaluate the competition in the Romanian banking system as regards the distortions in terms of market shares and the origin of capital, for the period 2000-2010, using the methodology of the structural analysis of the markets promoted by Mereuta (2012). Thus, we firstly check the features of structural distributions of the market shares in the case of the Romanian banking system, in the period 2000 2010; then we apply the Mereuta universal concentration matrix (2012) where we analyse the competition on the Romanian banking market, using two indicators: the M index and the degree of the structural dominance of the market leader (Gdl), and finally we conclude a "nodal" analysis of the Romanian banking system. Our approach demonstrates that all the structural peculiarities of the distributions of macro-experiment are confirmed in the Romanian banking system during the period 2000 - 2010 and that, in the period under review, the competition has continuously grown on the Romanian banking market, in particular due to the phenomenon of penetration of foreign capital. The distortions of competition in the light of the origin of the capital show that the penetration of foreign capital also increased its vulnerability and the risk of contagion. As regards policy recommendations for regulatory and supervisory authority, we suggest a very careful monitoring of soundness of all foreign banks, not only those from nodal countries; a close collaboration of National Bank of Romania (NBR) with the regulatory and supervisory authorities in the countries of origin of foreign banks branches; as well as a higher emphasis on the conduct of business of the banks and consumer protection. As for the banks management, we recommend that the stability of banks should be the main concern, rather than the preservation or increase in market shares
EXTERNAL FACTORS INFLUENCE ON INFLATION: THE CASE OF ROMANIA
No full textIn this paper we try to assess the main external determinants of inflation dynamics in Romania. The literature in the field of measuring inflation dynamics is wealthy and various. There are many developing country - level studies that examine inflation dynamics: Blavy (2004) - Guinea, Duma (2008) - Sri Lanka, Gottschalk et al (2008) - Sierra Leone, Moriyama (2008) - Sudan, Mwase (2006) - Tanzania, Williams and Adedeji (2004) - Dominican Republic, Hossain (2005) - Indonesia, Almounsor (2010) - Yemen. The issue of Romanian inflation dynamics is present in many and various studies, like Hammermann (2007), Pelinescu and Dospinescu (2006), Budina et al (2006) etc. There are no other recent studies that analyze the external determinants on Romanian inflation dynamics. In our paper we estimate an OLS single equation model, using a methodology derived from Almounsor (2010). The empirical analysis uses monthly data from August 2005 to January 2011. The start point of the data series is the moment of a major change in the National Bank of Romania (NBR) monetary policy: adoption of the inflation targeting regime. The independent variables used in our research are: harmonized consumer price index of EU-25 countries, EUR/RON exchange rate, crude oil price index (for analyzing the external shocks effect) and M2 monetary aggregate (intermediate money supply) as a control variable. The outcomes suggest that inflation in Romania is driven mainly by international price shocks - harmonized consumer price index of EU-25 countries. The EUR/RON exchange rate depreciation has a small influence on domestic inflation. In the short run, the effect of the international oil price is insignificant. Money supply, used here as a control variable, is shown to have a very small effect on inflation in Romania when using OLS regressions. The results show that 66% of the domestic inflation variance is explained by the independent variables in our model
THE REFORM OF NATIONAL BANK OF ROMANIA AFTER ACCESSION TO EU: CHALLENGES AND PERSPECTIVES
Get PDFIn January 2007, Romania had become a member of the European Union and the National Bank of Romania a member of The European System of Central Banks (ESCB). This event was a confirmation of the success of Romanian reforms, but, on the other hand, it was a beginning of a new stage in the process of accomplishing the nominal and real convergence conditions, set in the Maastricht Treaty. In this study we have done some considerations about the NBR's reform performances before and after EU accession and, also, we have talked about the main challenges and perspectives for Romanian central bank in the new economic environment imposed by the integration process.European integration, central bank, reform, challenges, perspectives
