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
Islamic Perspective on Financial Derivatives: Demand for Instruments of Risk Management in Various Businesses of Pakistan
Get PDFThis study was undertaken with the aim of exploring the legitimacy or otherwise of financial derivatives according to the Islamic commercial law, and ascertaining the demand for instruments of risk management in various business and economic sectors of Pakistan. The study drew the conclusion that forward contracts and futures contracts are allowed to benefit from. However, only hedgers can take advantage of them. These instruments can never be used for purely speculative purposes where making or taking delivery is not intended. Although it is not necessary to pay the complete price to the seller at the time of the contract yet some other precautionary measures such as a bank guarantee or a fair amount of money to be given to the seller should be taken to ensure that pure speculation is scrupulously forestalled and the delivery would certainly be made. If a large amount of money is given to the seller at the time of the contract the proscription of bai al-kali bil-kali would no longer be applicable because bai al-kali bil-kali comes about where the settlement by both parties is deferred to a future date, but that is not the case here. This amount of money would later on be adjusted to the total price. Options trading is also permissible because it is simply an extension of the fundamental concept of freedom and legitimacy given by the Shari’ah in relation to commercial transactions. However, those types of financial derivatives which involve riba such as interest-rate futures, interest-rate options, interest-rate swaps and swaptions are ruled out altogether and can never be taken advantage of. Similarly, those derivatives which proceed on gambling, inordinate uncertainty, alcohol, pork and other inadmissible commodities are precluded into the bargain.
To carry out the empirical part of the research, 600 questionnaires were randomly given out to the organizations operating in two commercial and industrial cities of Pakistan, namely Lahore and Faisalabad. The goal of the survey was to ascertain the demand for instruments of risk management in various business and economic sectors. The research findings indicated that there is demand for collateral, futures contracts, guarantee, and hatt wa ta’ajjal for credit risk management. As regards market risk management, arbun sale, bai al-salam, forward contracts, futures contracts, istijrar, istisna, and khiyar al-shart are in demand. In relation to currency risk management, foreign currency forwards, foreign currency futures, and foreign currency options are in demand. To mitigate interest-rate risk, forward rate agreements, interest-rate futures, and interest-rate options are in demand. The research findings further represented that a large number of the respondents want to use these instruments, if available, for hedging purposes.
The researcher learnt while administering the questionnaires that the respondents who do not want to utilize the instruments or techniques of risk management are either unacquainted with their structure or, quite often, not aware of their adequate and proper use. It was therefore proposed that the Islamic as well as conventional financial institutions had better provide their clientele and other business entrepreneurs with the required risk management counselling. Another issue is germane to the Islamic legal implications of foreign currency options, forward rate agreements and interest rate swaps permitted by the State Bank of Pakistan. The illicit features of these instruments ipso facto make them impracticable for those people who are desirous of using only Shari’ah-compliant instruments. It was thus suggested that the State Bank of Pakistan should also introduce other Shari’ah-compliant instruments, that is to say istisna, salam, bai al-arbun, istijrar, forward contracts, futures contracts, options and Islamic swaps, and allow Islamic as well as conventional banks to employ them for risk management. It is scrupulously hoped that some, if not all, parts of this research would be of benefit to and applied by the Islamic as well as conventional financial institutions in Pakistan and elsewhere
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
