Stable isotopes and element concentrations of samples from the Wadi Bih, United Arab Emirates

Ocean acidification triggered by Siberian Trap volcanism was a possible kill mechanism for the Permo-Triassic Boundary mass extinction, but direct evidence for an acidification event is lacking. We present a high-resolution seawater pH record across this interval, using boron isotope data combined with a quantitative modeling approach. In the latest Permian, increased ocean alkalinity primed the Earth system with a low level of atmospheric CO2 and a high ocean buffering capacity. The first phase of extinction was coincident with a slow injection of carbon into the atmosphere, and ocean pH remained stable. During the second extinction pulse, however, a rapid and large injection of carbon caused an abrupt acidification event that drove the preferential loss of heavily calcified marine biota.

Boards of directors and bank performance in United Arab Emirates

This study presents an empirical analysis about corporate governance of financial institutions in United Arab Emirates (UAE). The purpose of this research is to analyze the influence of the structure of board of directors on the performance of these institutions. To examine the effect of control exerted by particular families on bank management, we estimated models where the dependent variable is return on assets (ROA) and return on equity (ROE), independent variables are board of directors variables, and control variables are bank management variables. Our results show that the control of corporate governance by a ruler's family within a board of directors has a positive effect on bank profitability. Our results indicate that control by a ruler's family through a bank's board of directors compensates for the inadequacy of UAE's corporate governance system.
