Scholars from various disciplines address the ethical perspective of changing food habits in general, and the promotion of healthy eating in particular.
Addressing the persistent environmental threat of organic chemicals with a fresh approach to degradation and transformation processes, Organic Chemicals in the Environment: Mechanisms of Degradation and Transformation, Second Edition examines a wide range of compounds as well as abiotic and microbiological reactions mediated by microorganisms. The book emphasizes the pathways used and the broad classes of enzymes involved. It provides an overview of experimental procedures with detailed coverage of the organic compounds that are considered to be xenobiotics. The book begins by providing a broad perspective on abiotic and biotic reactions, including the significance of a range of environmental determinants. The following chapters briefly introduce experimental procedures and emphasize those procedures for establishing the structure of metabolites using isotopes and physical methods. Next, the authors outline details of biochemical reactions involved in the biodegradation of the major groups of aliphatic, carbocyclic aromatic, and heterocyclic compounds. They end with coverage of bioremediation that has attracted increasing concern because of the hazard presented by the disposal of unwanted chemicals or by-products from their manufacture. Broad and comprehensive, this book provides a cohesive treatment of the subject. It contains an extensive set of literature references and numerous illustrative figures. The authors use a mechanistic approach with emphasis on the pathways, and the principles that emerge provide a guide not only for specific compounds but also for those having a more remote structural resemblance.
This thoroughly revised second edition provides a critical overview of the contemporary debates and discussions surrounding gender and mediated communication. The book is divided into three parts: representing, producing, and consuming, with each section made up of three chapters. The first chapter of each section attempts to answer the most basic questions: ‘Who is represented?’, ‘Who produces what?’, and ‘Who consumes what?’. The second chapter of each section draws attention to the complexity of the relationship between gender and media, concentrating on the 'why'. The third and final chapter of each section addresses the latest debates in the fields of media and gender, adding a vital layer of understanding of the topic at hand. Throughout, text boxes provide additional information on the most important concepts and topics, and exercises help bridge the gap between theory and everyday life media practices. The second edition has been updated in light of current developments with regard to gender, media technologies, and globalisation, including recent theoretical insights and examples. This is an ideal textbook for students studying gender and media, and for general courses on gender studies, sociology, cultural studies, and women’s studies.
