This resource site has been designed to provide support and extension activities for all users of this text. Lecturers can use it to organize their teaching around the book and to provide additional support to help their students. Students who may be studying the subject for the first time can use it to help direct and reinforce their own learning.The site is divided into two areas, for the lecturer and student. All Palgrave Macmillan companion websites have free access; however, some lecturer resources are designated for exclusive use by adopters of the text and are therefore password-protected. To gain access to these parts of the website, lecturers will need to register and be authorized with a password by us. All users are invited to explore all other areas of the site as they please. We envisage this site to be used in tandem with the textbook to create and deliver a complete teaching package for lecturers and students.
