The book analyses organizations through four theoretical frameworks, offering students a clear structure they can use to understand complex organizational issues: ? the structural framework ? the Human Resources framework ? the power framework ? the symbolic framework Each framework is explored by a chapter covering the basics, followed by a more advanced chapter so that students can deepen their understanding. A case study at the end of the book draws together theory and practice,

Product Details 基本信息 ISBN-13 书号 9783030875008 Author 作者 Jesper Larsson Format 版本 平装-胶订 Pages Number 页数 159页 Publisher 出版社 Palgrave Macmillan Publication Date 出版日期 2021-11-21 Language 语种 其它(含多语) Book Contents 内容简介 This open access book uses an interdisciplinary approach that not only focuses on social organization but also analyzes how societies and ecological settings were interwoven. How did early modern indigenous Sami inhabitants in interior northwest Fennoscandia build institutions for governance of natural resources The book answers this question by exploring how they made decisions regarding natural resource management, mainly with regard to wild game, fish, and grazing land and illuminate how Sami users, in a changing economy, altered the long-term rules for use of land and water in a self-governance context. The early modern period was a transforming pha

Particular attention is given to balance of payments deficits and surpluses, and the profound difficulties of rebalancing the Euro area. Throughout the chapters, the author argues that the EMU has failed to support an optimal currency area with the correct institutional arrangements due to misunderstandings at a macroeconomic level. The author also sheds light on the stability pact and the resulting macroeconomic trap which has left a number of Eurozone countries with
