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
Financial Innovation In The Nigerian Stock Market: A Test of Casual Relationships Between Global Depository Receipts (GDRS) and Underlying Stocks
No full textThe modern competive world requires a lot of creativity, which warrants series of innovative activities by regulators, investors and firms in order to survive. Investment through Global Depository Receipts (GDRs) is one of such financial innovation tools that could be deployed to attract investors and enable survival in the modern competitive world. GDRs and their underlying shares should serve as perfect substitutes, which could in turn eliminate arbitrage opportunities. Most studies in emerging markets are concentrated in India most of which provide evidence of international integration of the stock market. This study, therefore, seeks to examine the direction of causality between GDRs and underlying shares in the Nigeria Stock Market, determine whether there is price transmission between GDRs and the underlying shares, and examine whether there is market integration between the London Stock Exchange and the Nigerian Stock market. The GDRs and underlying shares data were analysed using Pearson Correlation coefficient, unit root to determine the existence of shock, cointegration test to examine the long run relationship while Granger causality was used to examine the direction of causality between GDRs and their underlying shares. The results from the study indicates that GDRs and the underlying shares of these companies move in similar trend both in the short run and the long run. The results of the Granger causality on the other hand, showed that none of the GDRs and their underlying shares have a bidirectional causality. However, unidirectional relationship exists between two GDRs and their underlying shares. The results further confirm that the Nigerian stock market is not fully integrated. It is therefore recommended that relevant regulatory agencies like the Security and Exchance Commision (SEC) should create awareness on the availabilty of global depository receipts and how they can be accessed in the capital market, and the State should initiate policies that could help towards hedging against foreign exchange risks and associated management by encouraging investors to invest more on GDR
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
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
FAIR VALUE UNOBSERVABLE INPUTS ON THE VALUE RELEVANCE OF LISTED DEPOSIT MONEY BANKS (DMBs) IN NIGERIA
Full text linkThis study addressed the influence of fair value of unobservable inputs on the interrelationship between the value relevance of listed DMBs in Nigeria. The sample is comprised of ten (10) listed deposit money banks (DMBs) in Nigeria for seven (7) years (between 2012 and 2018). Secondary data were obtained from the annual reports and accounts of the listed DMBs in Nigeria and the panel multiple regression technique of data analysis was employed as the tool for analysis. Results from the regression analysis revealed that there is positive significant relationship between fair value unobservable inputs, book value per share on the value relevance of accounting information. Based on the findings it is therefore recommended that management of listed deposit money banks should take cognizance of fair value inputs when preparing financial statements
