Al0.5CoCrNiTi0.5 high-entropy alloy was synthesized by vacuum arc melting in a copper mold. This alloy was aged at 773 K to 1473 K (500 °C to 1200 °C) for 24 hours to investigate the microstructure and hardness. The hardness of the as-cast alloy is

In this article, we analyze German youth's health-compromising behaviors from the perspective of risk-taking behaviors. As with American youth, peer influence is found to be important not only on smoking and drinking behavior, but also on the percept

Viewing marijuana use as a risk-taking behavior, we find that the perception of high risk related to regular use of marijuana has no simple direct effect on that risk-taking behavior. Rather, the effect of risk perception is contingent upon the exten
