Ethical and regulatory controls in research involving human subjects are intended to encourage research without compromising high standards of health and safety.In recent years, regulatory agencies (Health and Welfare Canada, 1990) have begun to apply the practices of risk assessment (Bailar et al., 1993) and costbenefit analysis. Some countries are more highly advanced in this process than others, using risk assessment and cost-benefit principles extensively in designing regulations relating to health, safety and the environment. |
