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
External debt and macroeconomic vulnerability: A proposal for state-contingent debt contracts to achieve low-income country debt sustainability.
Get PDFWe argue that the 'New Debt Sustainability Framework' (DSF), as recently introduced by the Bretton Woods Institutions, is tailored to suit the aid allocation mechanism centred on the Country Policy and Institutional Assessment (CPIA), but fails to take into account low-income countries' economic vulnerability and exposure to exogenous shocks. As a result, the DSF further undermines the effective delivery of aid by the International Development Association (IDA), and fails to support recipient countries in their efforts to achieve lasting debt sustainability. Furthermore, we demonstrate that the findings of the empirical studies underlying the DSF and IDA14 replenishment are not robust to the introduction of vulnerability measures, such as the Economic Vulnerability Indicator (EVI), which undermine the significance of the CPIA in predicting debt distress episodes. In order to overcome the shortcomings of the DSF, we propose the introduction of a Contingency Debt Sustainability Framework (CDSF), which distinguishes between the causes of vulnerability underlying the external debt problem affecting most of the low-income countries. Drawing on the most established strands of sovereign debt and contract theory literature, we argue that state-contingent debt contracts represent the most effective financial instrument to link aid allocation and debt relief to recipient countries' financial requirements, contingent on the state of nature. To implement state-contingent contracts in the specific context of low-income debtor countries, we devise an accounting method by which shock and trend factors in the balance of payments are distinguished by their exogenous or endogenous origin. On the basis of this distinction, the CDSF financially compensates debtor countries for exogenous shock and trend factors, without giving rise to significant moral hazard implications. The CDSF is then simulated for the case of Uganda during the period 1988-2002, demonstrating its effectiveness in dealing with Uganda's severe exposure to price shocks and negative terms of trade
Myanmar's Trade and its Potential
Get PDFThe paper tabulates Myanmar's merchandise trade as reported by its partner countries, thereby circumventing the data constraints stemming from Myanmar's patchy trade records. It then estimates Myanmar's export potential, based on the bilateral export patterns observed for six other countries in Southeast Asia. Against that benchmark and controlling for outliers, Myanmar is found to be trading at about 15% its potential. The bulk of this gap is explained by very low trade with the industrialized countries. Through reintegration with the world economy accompanied by deep economic reforms domestically, Myanmar would be expected to be closing this gap rather swiftly
