The development of more efficient, ethical, and effective means of assessing the effects of chemicals on human health and the environment was a lifetime goal of Gilman Veith. His work has provided the foundation for the use of chemical structure for informing toxicological assessment by regulatory agencies the world over. Veith's scientific work influenced the early development of the SAR model...

Introduction France, with a deep agricultural heritage founded on familial farming, on the diversity of the "terroirs" and of the breeds (Cavailhes et al 1987, Brun et al 1989, Limouzin 1996), has a close and rich relationship with animal. The rural depopulation and urbanisation, moving the population away from farm animals while encouraging companion animals (Bonduelle and Joublin, 1995), the ...

Veterinarians serve two masters: animal patients and human clients. Both animal patients and human clients have legitimate interests, and conflicting moral claims may flow from these interests. Earlier research concludes that veterinary students are very much aware of the complex and often paradoxical relationship they have and will have with animals. In this article the views of veterinary stu...

Phenotypic variance results from variation in biological information possessed by individuals. Quantitative geneticists often strive to partition out all environmental variance to measure heritability. Behavioral biologists and ecologists however, require methods to integrate genetic and environmental components of inherited phenotypic variance in order to estimate the evolutionary potential of...

The discussion starts out with three examples of relationship matrices and their corresponding inverses. This illustrates two points: 1) any complete relationship inverse can be formed from the inverse of the relationships among parents; and 2) the only non-zero elements in the relationship inverse are between parents, parents and progeny, and between mates. Three equivalent models are develope...
