While risk assessment models attempt to predict human risk to toxicant exposure, in many cases these models cannot account for the wide variety of human responses. This review addresses several primary sources of heterogeneity that may affect individual responses to drug or toxicant exposure. Consideration was given to genetic polymorphisms, age-related factors during development and senescence...

In the near future we may be able to manipulate human embryos through genetic intervention. Jürgen Habermas has argued against the development of technologies which could make such intervention possible. His argument has received widespread criticism among bioethicists. These critics argue that Habermas’s argument relies on implausible assumptions about human nature. Moreover, they challenge Ha...

This article presents a framework for future research and program development designed to support children's peer-related social competence. Intervention research is examined within a historical perspective culminating with a discussion of contemporary translational approaches capable of integrating models of normative development, developmental models of risk and disability, and intervention s...
