This collection explores the nature and role of ethics within anarchist thought and practice, examining normative, meta-ethical and applied ethical issues through some of the theoretical insights of anarchism. It comprises contributions from international scholars working within the fields of philosophy and political theory.

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.

Rhys Matters, the first collection of essays focusing on Rhys's writing in over twenty years, encounters her oeuvre from multiple disciplinary perspectives and appreciates the interventions in modernism, postcolonial studies, Caribbean studies, and women's and gender studies.
