The resilience of Islamic Equity Funds during COVID-19: Evidence from risk adjusted performance, investment styles and volatility timing
No full textThis paper analyses the risk-adjusted performance of Islamic and conventional equity funds during the COVID-19 pandemic. We show that Islamic equity funds demonstrated differentials in risk-adjusted performance, investment styles, and volatility timing compared to their conventional counterparts. Specifically, the results revealed that Islamic equity funds are more resilient to COVID-19 shock since they outperformed non-Islamic peers during the peak months of the pandemic. The trend continues even when the spread smoothens. These findings confirm the safe-haven properties of Islamic equity funds, which is helpful for investors aiming to hedge pandemic risks. The style analysis reveals investment drift from riskier styles to more prudent options in response to each stage's uncertainties. The results suggest policymakers should further investigate Islamic financial assets and their underlying principles to improve the resilience of economic systems in any future black swan events
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
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
Islamic perspective of corporate governance: An introductory note
No full textThe concept of corporate governance is not new for institutions and organizations. The topic came into light after the financial crisis and frauds done by the companies. The topic of Islamic finance also gained momentum. Islamic Financial Services Board, Accounting and Auditing Organization of Islamic Financial Institutions, regulatory authorities of Islamic financial institutions and Islamic financial institutions themselves paid attention to the topic of corporate governance. Governance have critical place in Islam as human beings are answerable to Allah (swt) for acts, deeds, and fulfillment of responsibilities as vicegerent. This chapter focuses on the importance of corporate governance and differences between the corporate governance from conventional and Islamic point of view. How the topic of governance was discussed during the time of Holy Prophet (PBUH), different examples of the countries focusing on corporate governance are shared in this chapter
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
Shari’ah governance framework in different jurisdictions
No full textThe prime difference between conventional and Islamic financial institutions (IFIs)is the compliance with shari\u27ah. Hence, shari\u27ah is a very crucial pillar, rather a main pillar of Islamic finance. In order to ensure shari\u27ah compliance by the IFIs at all levels, central banks of different countries crafted and implemented shari\u27ah governance framework. This chapter focusses on the cross-country comparison of shari\u27ah governance framework. The countries included in this chapter are Malaysia, Pakistan, the United Kingdom and Bahrain. The result shows that Malaysia and Pakistan are leading in terms of comprehensive shari\u27ah governance framework whereas Bahrain comes next and the United Kingdom is the last in terms of comparison
