The impact of corporate social responsibility disclosure on financial performance : evidence from the GCC Islamic banking sector.
This paper examines the relationship between corporate social responsibility (CSR) and financial performance for Islamic banks in the Gulf Cooperation Council (GCC) region over the period 2000β2014 by generating CSR-related data through disclosure analysis of the annual reports of the sampled banks. The findings of this study indicate that there is a significant positive relationship between CSR disclosure and the financial performance of Islamic banks in the GCC countries. The results also show a positive relationship between CSR disclosure and the future financial performance of GCC Islamic banks, potentially indicating that current CSR activities carried out by Islamic banks in the GCC could have a long-term impact on their financial performance. Furthermore, despite demonstrating a significant positive relationship between the composite measure of the CSR disclosure index and financial performance, the findings show no statistically significant relationship between the individual dimensions of the CSR disclosure index and the current financial performance measure except for βmission and visionβ and βproducts and servicesβ. Similarly, the empirical results detect a positive significant association only between βmission and visionβ dimension and future financial performance of the examined banks
Root Herbivore Effects on Aboveground Multitrophic Interactions: Patterns, Processes and Mechanisms
In terrestrial food webs, the study of multitrophic interactions traditionally has focused on organisms that share a common domain, mainly above ground. In the last two decades, it has become clear that to further understand multitrophic interactions, the barrier between the belowground and aboveground domains has to be crossed. Belowground organisms that are intimately associated with the roots of terrestrial plants can influence the levels of primary and secondary chemistry and biomass of aboveground plant parts. These changes, in turn, influence the growth, development, and survival of aboveground insect herbivores. The discovery that soil organisms, which are usually out of sight and out of mind, can affect plant-herbivore interactions aboveground raised the question if and how higher trophic level organisms, such as carnivores, could be influenced. At present, the study of above-belowground interactions is evolving from interactions between organisms directly associated with the plant roots and shoots (e.g., root feeders - plant - foliar herbivores) to interactions involving members of higher trophic levels (e.g., parasitoids), as well as non-herbivorous organisms (e.g., decomposers, symbiotic plant mutualists, and pollinators). This multitrophic approach linking above- and belowground food webs aims at addressing interactions between plants, herbivores, and carnivores in a more realistic community setting. The ultimate goal is to understand the ecology and evolution of species in communities and, ultimately how community interactions contribute to the functioning of terrestrial ecosystems. Here, we summarize studies on the effects of root feeders on aboveground insect herbivores and parasitoids and discuss if there are common trends. We discuss the mechanisms that have been reported to mediate these effects, from changes in concentrations of plant nutritional quality and secondary chemistry to defense signaling. Finally, we discuss how the traditional framework of fixed paired combinations of root- and shoot-related organisms feeding on a common plant can be transformed into a more dynamic and realistic framework that incorporates community variation in species, densities, space and time, in order to gain further insight in this exciting and rapidly developing field
Effect of pulsed magnetic fields on bone appositional growth rate during the repair of transcortical holes: preliminary data.
The impact of sovereign rating news on European banks
This paper examines the spillover effect of Eurozone sovereign rating changes announced by Standard and Poor's, Moody's, and Fitch on domestic bank share prices in the period 2002-2012. This spillover effect appears negative in the case of downgrades, but insignificant for upgrades. Surprisingly, announcement of sovereign negative credit watches results in increased bank stock returns. Bank share price losses following sovereign downgrades increase as bank leverage, efficiency, and equity performance increase, and they decrease as bank systematic risk and payout ratio increase. On the contrary, bank share prices rise following sovereign negative credit watches, as leverage and bank size decrease and as bank systematic risk increases
