Sommario/riassunto |

We propose here a study of 'semiexact' and 'homological' categories as a basis for a generalised homological algebra. Our aim is to extend the homological notions to deeply non-abelian situations, where satellites and spectral sequences can still be studied.This is a sequel of a book on 'Homological Algebra, The interplay of homology with distributive lattices and orthodox semigroups', published by the same Editor, but can be read independently of the latter.The previous book develops homological algebra in p-exact categories, i.e. exact categories in the sense of Puppe and Mitchell - a modera |

Sommario/riassunto |
|
At the interface between culture and tourism lies a series of deep and challenging issues relating to how we deal with issues of political engagement, social justice, economic change, belonging, identity and meaning. This book introduces researchers, students and practitioners to a range of interesting and complex debates regarding the political and social implications of cultural tourism in a changing world. Concise and thematic theoretical sections provide the framework for a range of case studies, which contextualise and exemplify the issues raised. The book focuses on both traditional and popular culture, and explores some of the tensions between cultural preservation and social transformation. The book is divided into thematic sections - Politics and Policy; Community Participation and Empowerment; Authenticity and Commodification; and Interpretation and Representation - and will be of interest to all who wish to understand how cultural tourism continues to evolve as a focal point for understanding a changing world. |
