This study applied the theory and research on ethical practices of successful managers and ethics control mechanisms to identify the ethical climates that result in ethical behaviors in the banking. 141 employees from different banks in Shanghai, China, completed measures of all scales in the survey. The results support the theorizing of the value of well-formed business ethics in the banking in China. The correlation and structural equation analysis suggests that ethical practices of successful managers and ethics control mechanisms of banks reinforce three ethical climates of ‘service’, ‘law and rules’ and ‘caring’ that promote the ethical level of employees, and the independence and instrumental climate on the contrary. This study also found that there are three ethics control mechanisms most commonly used in the banking and ethics-focused reward system is believed to be a mostly effective one by the employees of banking in China.展开更多

One of the most interesting niches concerns the UAVs of moderate size （〈 1 m）, also called MAVs （micro air vehicles）. An aerodynamic study of the ULB （Universite Libre de Bruxelles） developed a ducted rotor MAV using the results of full-scale wind tunnel tests that allowed the determination of the platform speed envelope, the power requirements and the endurance characteristics for ISA sea level conditions. Although the ULB MAV appears similar to other ducted-rotor concepts, it fundamentally differs from them as it uses the downwash of a single rotor to compensate the electric motor main rotor torque and to achieve full control around the roll, pitch and yaw axes. This paper explains in detail the components layout of the MAV and the aerodynamic characteristics of the anti-torque blades.展开更多
