Cu2 ZnSnSe4 : How Far Does Off-Stoichiometry Go?

Sugarcane improvement: how far can we go?

In recent years, efforts to improve sugarcane have focused on the development of biotechnology for this crop. It has become clear that sugarcane lacks tools for the biotechnological route of improvement and that the initial efforts in sequencing ESTs had limited impact for breeding. Until recently, the models used by breeders in statistical genetics approaches have been developed for diploid or...

How far can behavior - based architectures go ?

Although the debate between \behavior-based" architectures and \symbol-processing" architectures is now over a decade old, there has been little progress in resolving it. I argue that this is due partly to the tendency of both sides to study only the problems to which their architectures are well suited and partly to the avoidance, again by both sides, of certain deep and diicult issues which I...

Expert Systems: How Far Can They Go?

What is the nature of the problem domains in which expert systems are likely to succeed and those in which they will not? Are there domains in which their use might be dangerous? How will their performance compare with that of human experts in the domain? Are there different facets of expertise that are not amenable to programming? How can human and machine expertise best be combined? To what e...

Trisomy 18: how far should we go.

Fluctuating asymmetry and animal welfare: how far are we? And how far should we go?

In the associated review, published in this issue of the Journal, Møller and Manning (2003) propose measures of developmental instability, primarily fluctuating asymmetry, for the assessment of animal welfare in agricultural practice. They see the advantages of fluctuating asymmetry in that it provides a single measure of organismal health that ‘‘can be used in all kinds of organisms including ...
