The Capital Asset Pricing Model (CAPM) is based on the Expected Utility (EU) theory that assumes linearity in probabilities and models the assumption of risk-aversion via a concave utility function. Studies in psychology and economics, however, show that individuals systematically violate the...

This paper questions the CAPM's assumption of global risk-aversion. I develop an expected return-risk framework that allows tests of restrictions on marginal utility conditional on the states-of-the-world. Empirical tests using monthly stock returns data show a decreasing marginal utility from...

This current experimental study explore the possible role of three Hg-resistant bacterial strains and their consortium in growth and promotion of mustard plant ( Brassica juncea ) under Hg-stress condition. For the study of potentials of bacterial strains under Hg stress condition, pot scale...

The study aims to see how effective Citrobacter species strain are in removing Hg II under stressful conditions. For this, a response surface methodology was chosen to optimized pH, temperature and biomass for effective biotransformation of Hg II . The optimized value for pH, temperature and...
