The foundations of a theory of nonminimal coupling of matter and the gravitational field in the framework of Riemannian (or Riemann-Cartan) geometry are presented. In the absence of matter, the Einstein vacuum field equations hold. In order to allow for a Newtonian limit, the theory contains a new parameter l0 of dimension length. For systems with finite total mass, l0 is set equal to the Schwarzschild radius.

In describing the flawless regularity of developmental processes and the correlation between changes at certain genetic loci and changes in morphology, biologists frequently employ two metaphors: that genes ‘control’ development, and that genomes embody ‘programs’ for development. Although these metaphors have an admirable sharpness and punch, they lead, when taken literally, to highly distorted pictures of developmental processes. A more balanced, and useful, view of the role of genes in development is that they act as suppliers of the material needs (...) of development and, in some instances, as context‐dependent catalysts of cellular changes, rather than as ‘controllers’ of developmental progress and direction. The consequences of adopting this alternative view of development are discussed. (shrink)

A new challenge for Bible translators A few decades ago the development of the dynamic-equivalent method of translation (which later became known as functional equivalence) broke radically away from the formal and traditional method of translation. Since then the functional-equivalent approach has undergone refinement, but the development can no longer be called revolutionary. However, research in the art of translation has now shifted from the method of translation to the format of the printed text (also called the paralinguistic features of (...) the text). In this article practical examples are given of how the employment of paralinguistic features can underscore the meaning of the text of the Bible, especially the Afrikaans Bible since it has become imperative to start working on a new translation.
