Chinese and Canadian Children's Evaluations of Lying and Truth Telling: Similarities and Dfferences in the Context of pro-and Antisocial Behaviors

The present study compared Chinese and Canadian children's moral evaluations of lie and truth telling in situations involving pro- and antisocial behaviors. Seven-, 9-, and 11-year-old Chinese and canadian children were presented 4 brief stories. Two stories involved a child who intentionally carried out a good deed, and the other2 stories involved a child who intentionally carried out a bad deed. When story characters were questioned by a teacher as to who had committed the deed, they either lied or told the truth. Children were asked to evaluate the story characters' deeds and their verbal statements. Overall, Chinese children rated truth telling less positively and lie telling more positively in prosocial settings than Canadian children, indicating that the emphasis on self-effacement and modesty in Chinese culture overrides Chinese children's evaluations of lying in some situations. Both Chinese and canadian children rated trugh telling positively and lie telling negatively in antisocial situations, reflecting the emphasis in both cultures on the distinction between misdeed and truth/lie telling. The findings of the present study suggest that, in the realm of lying and truth telling, a close relation between sociocultural practices and moral judgment exists. Specific social and cultural norms have an impact on children's developing moral judgments, which in turn, are modified by age and experience in a particular culture.     

Numerical investigation of cavitating flow behind the cone of a poppet valve in water hydraulic system

Computational Fluid Dynamics (CFD) simulations of cavitating flow through water hydraulic poppet valves were performed using advanced RNGk-epsilon turbulence model. The flow was turbulent, incompressible and unsteady, for Reynolds numbers greater than 43000. The working fluid was water, and the structure of the valve was simplified as a two dimensional axisymmetric geometrical model. Flow field visualization was numerically achieved. The effects of inlet velocity, outlet pressure, opening size as well as poppet angle on cavitation intensity in the poppet valve were numerically investigated. Experimental flow visualization was conducted to capture cavitation images near the orifice in the poppet valve with 30° poppet angle using high speed video camera. The binary cavitating flow field distribution obtained from digital processing of the original cavitation image showed a good agreement with the numerical result.
