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 Finance: Principles, Performance and Prospects
No full textThis book demonstrates how the global market for Islamic financial services has shown strong growth in recent years and shown remarkable resilience during the global financial crisis. Drawing on a range of international perspectives from the Gulf Cooperation Council countries, Malaysia, Pakistan, Australia and Europe, this book explores the characteristics and performance of Islamic finance and banking and discusses future prospects. It offers a comprehensive theoretical framework for Shariah governance in Islamic financial institutions, explores Shariah-compliant equities, as well as issues in productivity, technology and efficiency. It includes a number of comparative studies on Islamic and conventional banks, Islamic and conventional unit trusts, and Islamic and conventional banks’ product mixes. The challenges and opportunities for the expansion of Islamic finance and banking into Europe are explored through the contexts of the UK, Germany and Italy
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

Market risk management in Islamic finance : an economic analysis of the rationale, permissibility and usage of derivative hedging instruments
Get PDFThe examination of the topic of market risk management in Islamic finance is a
complex endeavour. At a basic level, the subject matter, being multifarious in a
manner that mixes religion and economics, requires the conjoining of religious faith
with scientific objectivity in order to ascertain the truth contained in the scripture as
it pertains to the Mua’amalat (dealings between individuals) matter of entering into
financial contracts with others to manage market risk exposures.
Moreover, the complexity is compounded due to the need to disentangle the
ambiguity that has beset the discourse on the topic due to historically being mostly
legal-centric with a focus on debating the contractual elements rather than attempting
to comprehensively address the myriad issues that relate to market risk management
in contemporary contexts. These issues, for the most part, revolve around the reliance
on market risk transfer as a strategy and derivative contracts, with monetary
underlying variables, as tools to implement that strategy.
Thus, the journey of investigating the rationale, permissibility, and usage of
derivative hedging instruments for market risk management in Islamic finance is,
essentially, an undertaking that seeks to engage in a wide-ranging and multi-layered
examination of the subject matter as well as the exploration of new areas of relative
significance. This, in turn, and subsequent to the analysis of data generated from
documentary sources and forty-one interviews which were collected from numerous
sources within four locations, led to the elaboration of the contention that market risk
management through derivative instruments for legitimate hedging purposes should
not be prohibited in the Shari’a, albeit with certain conditions that limit unproductive
behaviour.
The basis for the aforementioned contention is built on the fact that market risk
management has undergone a paradigm shift in how exposures are identified and
measured as well as in the emergence of innovative tools which can result in a better
ability to address the opportunities and challenges facing institutions that provide
value to society (i.e., the real sector). Moreover, there is little substantive evidence
that proves that the utilization of derivative instruments for hedging purposes leads
its users to partaking in transactions that circumvent the prohibition of Riba (usury),
Gharar (excessive uncertainty), and Maysir (gambling).
In effect, the derivative instruments used for the management of market risks are not
only disassociated from usurious debt transactions, they are also transacted in the
financial markets in a manner that is transparent to all the parties involved. Along the
same lines, the prohibition of Maysir, which is apparently an overarching concern,
should be conceptualized with the focus on the proscription of the act of gambling,
not necessarily the instruments (e.g., derivatives) and/or any particular framework
(e.g., zero-sum arrangements).
Ultimately, one should be cognizant of the fact that the true intentions of Islamic
jurisprudence in Mua’amalat (as a manifestation of divine guidance) always centre
on human well-being. Accordingly, the religious prohibitions are, in essence, within
the realm of acts that adversely affect human well-being. This is a constant theme
that is present throughout the thesis; and is one that exists at the heart of a wider
aspiration of its adoption to a greater extent than is currently present in the Islamic
finance discourse
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
