Why CEOs invest in Corporate Social Responsibility initiatives: evidence on Shariah compliant firms
No full textThe aim of this article is to investigate the motivation of CEOs to invest in Corporate Social Responsibility (CSR) activities. To carry out this analysis, we assess a sample of US conventional and Shariah Compliant (SC) firms, from Dow Jones Indices. As SC firms undergo business and financial screening, they are expected to follow different managerial styles and capital structures as compared to conventional firms. This comparison is important in view of the growing size of the Islamic Financial Services Industry that has surpassed total asset values of USD 2.00 Trillion. Existing literature argues that, for conventional firms, CEOs spend on CSR either to promote their private benefits (agency view) or to reduce conflicts among shareholders (conflict resolution view). Our results provide evidence that across both types of firms, CEOs do not invest in CSR initiatives to pursue selfish motives but to resolve conflicts among stakeholders to maximize firm value. The findings are also robust across different specifications and methods in order to address endogeneity issues. This article contributes to the growing literature on managerial styles, capital structure and Islamic Finance, carrying out important implications for the investment industry and for the long-term value of the firm
Cryptocurrencies versus environmentally sustainable assets: Does a perfect hedge exist?
No full textIn the wake of proliferation of cryptocurrencies and growing concerns regarding their environmental impact, we investigate the dynamic co-movement of digital assets and environmentally sustainable assets. We use daily data of five global indices from 01 March 2017 to 15 May 2022. The results suggest that environmentally sustainable indices and cryptocurrency indices demonstrate co-movements during pandemic. However, in the normal times, they mostly remain detached from each other. Therefore, it can be argued that both the asset classes can serve as hedge against each other. The findings carry important implications for the investment industry and regulators.Other Information Published in: International Review of Economics & Finance License: http://creativecommons.org/licenses/by/4.0/See article on publisher's website: https://dx.doi.org/10.1016/j.iref.2023.02.005</p
SPICE‐compliant load flow analysis of power distribution networks with behavioral loads
No full textThis paper discusses an alternative and Simulation Program with Integrated Circuit Emphasis (SPICE)-compatible solution for the steady-state simulation of power distribution networks. It introduces two alternative auxiliary subcircuits that allow to efficiently simulate the network in any simulation tool for circuit analysis. This feature introduces remarkable benefits in terms of simplicity and generality, since it avoids the need for any iterative method, thus bridging the gap between classical industry-standard and general-purpose simulators based on circuital equations, such as SPICE, and dedicated tools for the load flow analysis of power systems. The approach is first demonstrated based on a simple illustrative example, for which the performance in terms of accuracy and efficiency is discussed and then applied to the standard IEEE 33-node power distribution benchmark
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Modulation of the organelle specificity in Re(i) tetrazolato complexes leads to labeling of lipid droplets

The emission signal detected from the live insect Drosophila and human cell lines, generated by exploiting two-photon excitation at 830 nm to reduce cellular damage and autofluorescence, suggests photophysical properties that are analogous to those measured from dilute solutions, meaning that the complexes remain intact within the cellular environment. Moreover, the rhenium complex linked to 4-cyanophenyltetrazolate shows high specificity for the lipid droplets, whereas the complex bound to 3-pyridyltetrazolate tends to localise within the lysosomes. This differential localisation implies that in these complexes, organelle specificity can be achieved and manipulated by simple functional group transformations thus avoiding more complex bioconjugation strategies. More importantly, these results highlight the first example of phosphorescent labeling of the lipid droplets, whose important cellular functions have been recently highlighted along with the fact that their role in the metabolism of healthy and diseased cells has not been fully elucidated.Christie A.

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
Dividend policy: The case of Shariah-compliant firms
No full textShariah-compliant firms (SCF) cannot use debt to mitigate agency problems, and in this scenario the dividend payout policy becomes a highly important tool of corporate governance for shariah-compliant investors. This chapter highlights the dividend payout behaviour of SCF by comparing them to conventional firms. We performed a detailed review of existing literature and also calculated descriptive statistics, using various specifications using a sample of representative SCF and market firms for United States (US) market from 2006-2015, in order to investigate if the dividend payout behaviour of SCF differs from the market. However, we did not find any notable difference. Our results also showed no difference in payout decisions at different levels of idiosyncratic risk. In summary, we observed that firms with good governance, large asset size, higher profitability, higher Retained Earnings/Total Earnings (RE/TE) and lower market-book ratio, lower idiosyncratic risk and lower financial constraints, on average, pay higher dividends. The results remain similar across both kinds of firms
Author's address:
No full textCan archives of audiovisual TV interviews be used to make authors more visible to students, and thereby reduce the learning gap between native and non-native language speakers in college classes? We examined students in a college course who learned about one scholar's ideas through watching an audiovisual TV interview (i.e., visible author format) and about another scholar's ideas through reading a formal text description (i.e., invisible author format). For the invisible author, native language speakers scored significantly higher than the non-native language speakers on a corresponding exam question (i.e., a cognitive measure), generated more words on the exam question (i.e., a motivational measure), and mentioned the author's name more often in answering the exam question (i.e., an affective measure). For the visible author, the groups did not differ on any of these measures. These findings provide evidence for the idea that making the author visible through audiovisual TV interviews can eliminate the learning gap between native and non-native language speakers. 3 Universities around the world serve students who are non-native speakers of th
