1 The MetaFrameEnvironment MetaFrame is a meta-level framework designed to ooer a sophisticated support for the systematic and structured computer aided generation of application-speciic complex objects from collections of reusable components. Figure 1 shows its overall organization. Special care has been taken in the design of an adequate, almost natural-language speciication language, of a us...

Milk, meat and eggs tend not to be regarded as an important source of PUFA. They are disproportionally high in SFA compared with their PUFA content, especially those from cattle and sheep, since their rumen microbes are responsible for the loss of over 90 % of PUFA intake by livestock. This need not necessarily be the case since the relative proportion of PUFA in these foods is dictated by live...

Economic choice entails assigning values to the available options and is impaired by lesions to the orbitofrontal cortex (OFC). Recent results show that some neurons in the OFC encode the values that monkeys (Macaca mulatta) assign to different goods when they choose between them. A broad and fundamental question is how this neuronal representation of value depends on the behavioral context. He...
