The study of biofilm considers the close association of micro-organisms with each other at interfaces and the consequent physiological adaptation to the proximity of other cells and surfaces. As such it is relevant to a variety of disciplines, including medicine, dentistry, bioremediation, biofouling, water technology, engineering and food science. Although the habitats studied, and their associated cellular communities, differ widely, some common elements exist such as method of attachment, coadhesion, regulation of biofilm phenotype and biofilm architecture. This book aims to distil the common principles of biofilm physiology and growth for all interested disciplines. It will appeal to the specialist biofilm researcher as well as to students wishing to introduce themselves to the topic.

First published in 1992. This book aims to bring the reader up to date on current research, theory and conceptualisations of the depressive disorders. It offers a new perspective derived from evolution theory and argues for the adoption of the biopsycho­ social model. Part I explores the major distinctions between all types of depression, including discussion of seasonal affective disorder, postnatal depression and depression in children. The chapter on epidemiology covers issues of prevalence, relapse, long term outcome and chronic depression. The relationship between depression and various approaches to personality and personality disorder are also covered in detail. Part II offers an overview of evolution theory and its application to depression. Special attention is given to social comparison, submissive behaviour, sense of inferiority, helplessness and weakness, shame, guilt, anger and resentment, and envy in depression. These are seen to relate to two basic, central human concerns, social power and belonging. This approach offers a coherent account of why these various aspects of functioning are often part of depressive experience. Part III covers the major theories of depression, including psychoanalytic, object relations, archetype, mentality, attachment, self psychology, incentive, cognitive, behavioural and social. Theories are compared and contrasted, highlighting controversies, weaknesses and strengths, and where cross fertilisation of ideas may be beneficial. The final chapter outlines why simple theories of aetiology are inadequate and explores the role of culture and social relationships as elicitors of many forms of depression.
