Juta's nursing psychology is aimed at nursing professionals to enable them to apply psychological concepts to nursing practice and so assist them in their day-to-day contact with patients. It examines human behaviour in a holistic way, and this means considering the whole person: brain, nervous system, personality, stage of life, social relationships and so on. The selection of topics in Juta's nursing psychology makes this holistic view a reality and includes: the biological basis of human behaviour; human development across the lifespan, including the social context; psychological approaches to health and ill-health; an introduction to counselling.

"Ecosystem" is an intuitively appealing concept to most ecologists, but, in spite of its widespread use, the term remains diffuse and ambiguous. The authors of this book argue that previous attempts to define the concept have been derived from particular viewpoints to the exclusion of others equally possible. They offer instead a more general line of thought based on hierarchy theory. Their contribution should help to counteract the present separation of subdisciplines in ecology and to bring functional and population/community ecologists closer to a common approach.

Developed as a way of understanding highly complex organized systems, hierarchy theory has at its center the idea that organization results from differences in process rates. To the authors the theory suggests an objective way of decomposing ecosystems into their component parts. The results thus obtained offer a rewarding method for integrating various schools of ecology.
