Opis:
European Union banks were severely hit by the global fi nancial crisis in 2008 and their stock prices and returns have generally not recovered since then, differently to what has been observed in other sectors (i.e., non-fi nancial corporations) and jurisdictions (i.e., US). In this paper, we focus on three episodes of fi nancial turmoil in EU fi nancial markets occurring after the global fi nancial crisis (August 2015, December 2015 and January 2016, and June 2016) and, through a series of linear regressions, with and without control variables, attempt to determine the common features of those banks which stock returns declined the most. Results of the regressions tend to suggest that size has been driving the decreases in stock returns in the three episodes. Regarding asset quality, the Texas ratio has been a decisive factor in the evolution of stock returns of EU banks in the second and third periods. Interestingly, profi tability variables seem not to be statistically signifi cant to explain the declines in stock returns, except in the third period, but only under some specifi cations. An evolution on the perception by fi nancial market participants on EU banks, with a larger importance on asset quality in the latter periods, can also be observed. Lastly, on the basis of these results, further policy actions would be needed to clean-up the balance sheet of banks, as a necessary step towards full recovery after the global fi nancial crisis.

Opis:
The mineralogy and thermal properties of two kaolin clay samples from Agua Blanca (Hidalgo-México) were determined by XRD, SEM-EDS, TGA-DSC techniques. Kaolin clay A contains a higher $Al_2O_3$ and lower impurities $(K_2O, TiO_2, Fe_2O_3)$ amount than kaolin clay B, while the SiO2 amount is similar for both kaolin clays. A theoretical approach was carried out by a thermodynamic analysis considering the chemical composition of both kaolin clay samples with the FactSage 7.3 software. Stability phase diagrams were obtained to different K2O content from 0.1 to 3 wt % and temperatures in the range from 600 to 1600°C based on the chemical composition of the kaolin clay samples. The main mineralogical compounds predicted are andalusite $(Al_2O_3•SiO_2)$, K-Potash feldspar $(K_2O•Al_2O_3•6SiO_2)$, and the $SiO_2$ polymorphs (quartz, tridymite, and cristobalite) with small amounts of ferric-pseudobrookite $(Fe_2O_5Ti)$, and rutile $(TiO_2)$. As $K_2O$ content is increased, the amounts of mullite and tridymite decrease meanwhile the potash feld spar is increased at high temperatures. A liquid phase is formed at around 1350 and 1400°C for the kaolin clay samples A and B, respectively. The viscosity of the melt is increased for the evaluated $K_2O$ additions to 1400, 1500, and 1600°C.
