The central theme of this book is the role of energetical factors in the regulation of human information processing activity. This is a restatement of one of the classic problems of psychology - that of acc- ounting for motivational or intensive aspects of behaviour, as opposed to structural or directional aspects. The term "energetics" was first used in the 1930's by Freeman, Duffy and others, following Cannon's energy mobilization view of emotion and motivation. The original concept had a limited life, probably because of its unnecessary focus on relativ- ely peripheral processes, but it...

Increased interest in the basic biology of plants and microorganisms stems from the fact that crop productivity is directly affected by plant-microbe interactions. In spite of the fact that plants exist in the environment amongst diverse species of microorganisms, only a few ever establish a direct relationship. Emerging awareness concerning the indirect effect of microbial association on plant growth and the possibility of using one microbe against another for controlling pathogenic interactions is at the genesis of new fields of studies. The primary reason for a microbe to associate with-...

The history of Jean de Labadie and the Labadists has re- ceived attention through the years. That attention, however, has more often than not fallen short in its tracing of Labadie's 'double migration'. Disaffected with the established church order of his day and motivated by a sense of prophetic mis- sion to establish again the life of the primitive church, this spiritual nomad wandered from France to Switzerland, then to the United Provinces, Germany and Denmark, according to the vicissitudes of the times. As he went, he changed his affiliations from 'high' church ever 'lower', from the...

One ofthe most important features of the development of physical and mathematical sciences in the beginning of the 20th century was the demolition of prevailing views of the three-dimensional Euclidean space as the only possible mathematical description of real physical space. Apriorization of geometrical notions and identification of physical 3 space with its mathematical modellR were characteristic for these views. The discovery of non-Euclidean geometries led mathematicians to the understanding that Euclidean geometry is nothing more than one of many logically admissible geometrical...

Since the beginning of agricultural production, there has been a continuous effort to grow more and better quality food to feed ever increasing popula- tions. Both improved cultural practices and improved crop plants have allowed us to divert more human resources to non-agricultural activities while still increasing agricultural production. Malthusian population predictions continue to alarm agricultural researchers, especially plant breeders, to seek new technologies that will continue to allow us to produce more and better food by fewer people on less land. Both improvement of existing...

This volume contains the proceedings of a NATO Advanced Research Workshop (ARW) on the topic of "Changes in Speech and Face Processing in Infancy: A glimpse at Developmental Mechanisms of Cognition," which was held in Carry-Ie-Rouet (France) at the Vacanciel "La Calanque," from June 29 to July 3, 1992. For many years, developmental researchers have been systematically exploring what is concealed by the blooming and buzzing confusion (as William James described the infant's world). Much research has been carried out on the mechanisms by which organisms recognize and relate to their...
