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
Implications of cross-border banking for financial integration in the West African sub-region
No full textThe paper sets out to review developments in cross-border banking in the West African sub-region and implications of the growth of cross-border banking institutions for financial integration in West Africa. This paper noted that initial efforts at cross-border banking in the sub-region were led by Ecobank Transnational Incorporated with the active support of the Economic Community of |West African States (ECOWAS), which acquired substantial shares in the bank, Regional approach to cross-border banking and financial integration in the sub-region has complimented the market approach facilitated by private enterprise. Regional efforts have been intensified but problems remain with the numerous barriers to the free movement of goods, services and capital. While cross-border banking can facilitate financial integration, there are a number of implications which require policy remedial actions and safeguards for the benefits of cross-border banking to be enjoyed by both home and host economies. The safeguards are in the areas of cooperation between home and host regulators and supervisors to ensure that cross-border banks are comprehensively supervised as well as ensure that risks are identified and analyzed wherever they occurred. The exchange of information between regulators and application of risk-based consolidated supervision is necessary to contain systemic risks. The paper concluded that the issue is not to halt financial globalization but, to put in place, mechanisms that will detect banking crises before they occur; and when they do occur, to apply remedial actions to contain and reverse the problems
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
Issues in exchange rate policy design and management
No full textThis paper focused on the major issues and highlighted the factors which are crucial in the design of exchange rate policy. It also reviewed exchange rate policy in Nigeria since independence. After a brief review of models of exchange rate determination and exchange rate mechanisms, it concluded that exchange rate adjustment is required to correct flow balance of payments deficit, while reserves draw down, in addition to demand management, could prove efficacious in reversing a temporary or stock balance of payments deficit. The links between the monetary, fiscal and external accounts were provided in order to properly guide policy makers on the options to settle for in designing exchange rate policy. This is because the exchange rate affects all sectors of the economy, since it influences resource allocation, through its ability to stimulate movements in other prices. The paper was concluded on the note that the current exchange rate policy should be sustained and complemented with the application of accommodating fiscal and monetary policy measures
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
The purchasing power parity (PPP) measure of Naira\u27s equilibrium exchange rate
No full textThis paper examined the relevance of the Purchasing Power Parity (PPP) concept in exchange rate analysis using Nigerian data. In this direction, the paper attempted to explore the relationship between the nominal exchange rate and relative prices to establish whether a long run relationship exists between them, and to determine whether the exchange rate is at a competitive level
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
