Online Peer-to-Peer (P2P) lending marketplaces allow individuals to lend and borrow directly among each other without the mediation of a creditor bank institution. Prior literature has examined online P2P, but has largely been limited to the Western context. This paper thus explores how social...

Oxy-coal combustion produces a combustion environment that contains large amounts of CO2, H2O compared to conventional air combustion. Silica (SiO2) is a major component of the mineral impurities in coal and the vaporization of silicon containing species controls the initial phase of formation...

Little work has been performed on the importance of sodium and its occurrence in coal to PM2.5 (particles less than 2.5μm in aerodynamic diameter) reduction by kaolin during O2/N2 combustion and O2/CO2 combustion at high temperatures. In this study, the combustion experiment of a treated...

We intend to reveal the causes and the determinants of the omitted shareholder proposals. We find that individual investors are mostly likely to submit a proposal being excluded from the proxy ballot. Since individual investors are not so skillful as institutional investors, we summarize that...
