...The cultural and economic trends of Cinema in Ireland and Wales Acknowledgements This audit of cinemas in Ireland and Wales was commissioned by Sgrîn Cymru Wales and the Arts Council. The study was financially supported by the Ireland/Wales Interreg IIIA Community Initiative Programme: ERDF 2000–2006. Throughout the study we have been fortunate to benefit from the knowledge, enthusiasm and commitment of Rhian Iolo (Exhibition Manager, Sgrîn) and Siobhan Bourke (Film Adviser, Arts Council). Additional invaluable assistance was provided by Stephanie O’Callaghan, Michelle Hoctor, Antoinette O’Neill, and the staff at both Sgrîn and the Arts Council of Ireland. This study would not have been possible without the generous contribution of time, expertise and information from the many cinema owners, managers, projection and customer services staff we met during the study.

.... Organization Theory Challenges and Perspectives John McAuley, Joanne Duberley and Phil Johnson . This book is, to my knowledge, the most comprehensive and reliable guide to organisational theory currently available. What is needed is a text that will give a good idea of the breadth and complexity of this important subject, and this is precisely what McAuley, Duberley and Johnson have provided. They have done some sterling service in bringing together the very diverse strands of work that today qualify as constituting the subject of organisational theory. Whilst their writing is accessible and engaging, their approach is scholarly and serious. It is so easy for students (and indeed others who should know better) to trivialize this very problematic and challenging subject. This is not the case with the present book. This is a book that deserves to achieve a wide readership. Professor Stephen Ackroyd, Lancaster University, UK This new textbook usefully situates organization theory within the scholarly debates on modernism and postmodernism, and provides an advanced introduction to the heterogeneous study of organizations, including chapters on phenomenology, critical theory and psychoanalysis. Like all good textbooks, the book is accessible, well researched and readers are encouraged to view chapters as a starting point for getting to grips with the field of organization theory. Dr Martin Brigham, Lancaster University, UK McAuley et al. provide a highly readable account...
