Buch. Etat : Neu. Neuware -This open access book explores what makes women decide to pursue a career in male-dominated fields such as information technology (IT). It reveals how women experience gendered stereotypes but also how they bypass, negotiate, and challenge such stereotypes, reconstructing gender-technology relations in the process. Using the example of Norway to illuminate this challenge in Western countries, the book includes a discussion of the ¿gender equality paradox¿, where gender equality exists in parallel with gender segregation in fields such as IT. The discussion illustrates how the norm of gender equality in some cases hinders rather than promotes efforts to increase women¿s participation in technology-related roles.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 152 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -This open access book aims to emphasize the potential for Japan, Europe and Indo-Pacific countries including the US to respond to shared domestic and international challenges on finding joint ways to uphold and develop the liberal international order (LIO) in the Asian Pacific region and the world. It explores how these countries and the region (the EU) can work together to promote solidarity and cooperation to advance democratic standards and rules-based norms globally.The US understands the LIO in a political sense and centers its focus on democracy, aiming to build a coalition of democracies opposed to China and Russia which represent a kind of authoritarian axis. The US aims both to defend the LIO and respond to the China challenge and to build a coalition of countries that will do both. In contrast European countries aim at defending the ¿rules-based order¿¿a term preferred because they fear that the concept of the LIO might alienate or antagonize non-democratic countries. They face a dilemma between working with China to reform the LIO or, in seeking to defend it from China, excluding China. Germany and France differ regarding whether to play a passive or active role in the Indo-Pacific, the former choosing to preserve peace and stability for continued exports, and, until recently, doing little to contribute to security. Its views echo those of the ASEAN countries, which are unable or unwilling to take an active role in protecting the LIO. On the contrary France, along with the UK, actively carries out presence operations in the Indo-Pacific. Rather than upholding US dominance, France supports a multipolar order that will also reduce Chinäs influence in the region, with France acting as a balancing power and offering an alternative to the choice between China and the United States. Japan and India show interest in European views with the former leaning more toward its allies, the US and AUKUS, and the latter seeing Europe less as an alternativeto the status quo and more as a complement of QUAD. This book concludes that the US needs to build coalitions rather than forcing allies and neighbors to choose sides, while Japan, Asian countries, and Europeans should more actively reform the LIO.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 144 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -This book highlights unique and deeper insights into the operations of off-grid water supply business models and the policy implications that they raise. The two key research questions of the report are as follows: 1) What is the efficacy and sustainability of the off-grid model of safe water availability and/or delivery to consumers who don¿t have piped water supply 2) What are the key policy considerations for planning a successful off-grid model of safe water delivery Through the Four-Domain Framework, this book does the gap analysis of the physical, operational, financial, and institutional domains of the few off-grid water operators in cross-country case studies. It also includes a detailed financial analysis of the capital costs as well as operations and maintenance costs of the different off-grid water supply models compared to some of the piped water supply models. The final discusses the need to acknowledge off-grid water solutions in urban water policies, especially for the economically weaker sections. The universal coverage of all by the piped water is an ultimate goal of any water policy; however, in the interim, there is a need to put more emphasis on off-grid water solutions.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 148 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -This open access book connects Jane Jacobs's celebrated urban analysis to her ideas on economics and social theory. While Jacobs is a legend in the field of urbanism and famous for challenging and profoundly influencing urban planning and design, her theoretical contributions ¿ although central to her criticisms of and proposals for public policy ¿ are frequently overlooked even by her most enthusiastic admirers. This book argues that Jacobs¿s insight that ¿a city cannot be a work of art¿ underlies both her ideas on planning and her understanding of economic development and social cooperation. It shows how the theory of the market process and Jacobs¿s theory of urban processes are useful complements ¿ an example of what economists and urbanists can learn from each other. This Jacobs-cum-market-process perspective offers new theoretical, historical, and policy analyses of cities, more realistic and coherent than standard accounts by either economists or urbanists.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 428 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -This book introduces readers to the history of design thinking in pre-modern China. The content is structured according to successive dynasties, covering the seven major periods of the pre-Qin, Qin and Han, Wei and Jin, Sui and Tang, Song and Yuan, Ming, and Qing dynasties. Each chapter introduces the most representative individuals of the period and discusses their work and ideas in order to reveal the national and cultural features of the respective periods. A distinctive feature of cultural identity running through the long course of Chinäs historical development is the argument that actions are determined by ideas: Such a view can be found in long-standing thinking on art, design, and creativity. The book demonstrates that conscious design is the vital link between the ideas that constitute human cultures and the physical objects that make up their resulting material cultures. It is the attribute of design that defines what it is to be human and also produces the physical evidence of the evolution of Chinese civilization. The book reveals the integrated characteristics of Chinese culture and art and shows how both changing and recurring ideologies have influenced Chinese design practice since the ancient Shang and Zhou dynasties and how these forces have shaped the spirit and materiality of Chinese civilization. Design is the cornerstone that has made China one of the major contributors to human civilization throughout the thousands of years of its history.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 288 pp. Englisch.
