In recent years an increasing number of scholars have incorporated a focus on emotions in their theories of material culture, transnationalism and globalization, and this book aims to contribute to this field of inquiry. It examines how ‘emotions’ can be theorized, and serves as a useful analytical tool for understanding the interrelated mobility of humans, objects and images. Ethnographically rich, and theoretically grounded case studies offer new perspectives on the relations between migration, material culture and emotions. While some chapters address the many different ways in which migrants and migrant artists express their emotions through objects and images in transnational contexts, other chapters focus on how particular works of art, everyday objects and artefacts can evoke feelings specific to particular migrant groups and communities. Case studies also analyse how artists, academics and policy makers can stimulate positive interaction between migrants and non-migrant communities.

We live in an age of rapid technological development. The Internet already affects our lives in many ways. Indeed, we continue to depend more, and more intrinsically, on the Internet, which is increasingly becoming a fundamental piece of societal infrastructure, just as water supply, electricity grids, and transportation networks have been for a long time. But while these other infrastructures are relatively static, the Internet is undergoing swift and fundamental change: Notably, the Internet is going mobile. The world has some 6.7 billion humans, 4 billion mobile phones, and 1.7 billion Internet users. The two most populous continents, Asia and Africa, have relatively low Internet penetration and hold the greatest potentials for growth. Their mobile phone users by far outnumber their Internet users, and the numbers are growing rapidly. China and India are each gaining about half a dozen million new phone users per month. Users across the globe as a whole increasingly embrace mobile Internet devices, with smart phone sales are starting to outnumber PC sales. Indeed, these and other facts suggest that the Internet stands to gain a substantial mobile component. This mega trend towards “mobile” is enabled by rapid and continuing advances in key technology areas such as mobile communication, consumer electronics, g- positioning, and computing. In short, this is the backdrop for this very timely book on moving objects by Xiaofeng Meng and Jidong Chen.

Moving Objects Databases is the first uniform treatment of moving objects databases, the technology that supports GPS and RFID. It focuses on the modeling and design of data from moving objects — such as people, animals, vehicles, hurricanes, forest fires, oil spills, armies, or other objects — as well as the storage, retrieval, and querying of that very voluminous data. It includes homework assignments at the end of each chapter, exercises throughout the text that students can complete as they read, and a solutions manual in the back of the book. This book is intended for graduate or advanced undergraduate students. It is also recommended for computer scientists and database systems engineers and programmers in government, industry and academia; professionals from other disciplines, e.g., geography, geology, soil science, hydrology, urban and regional planning, mobile computing, bioterrorism and homeland security, etc. - Focuses on the modeling and design of data from moving objects--such as people, animals, vehicles, hurricanes, forest fires, oil spills, armies, or other objects--as well as the storage, retrieval, and querying of that very voluminous data. - Demonstrates through many practical examples and illustrations how new concepts and techniques are used to integrate time and space in database applications. - Provides exercises and solutions in each chapter to enable the reader to explore recent research results in practice.

Moving Objects deals with emotive design: designed objects that demand to be engaged with rather than simply used. If postmodernism depended upon ironic distance, and Critical Design is all about questions, then emotive design runs hotter than this, confronting how designers are using feelings in what they make. Damon Taylor's original study considers these emotionally laden, highly authored works, often produced in limited editions and sold like art – objects such as a chair made from cuddly toys, a leather sofa that resembles a cow, and a jewellery box fashioned from human hair. Tracing the phenomenon back to the 'Dutch inflection' that began with Droog designers like Jurgen Bey and Hella Jongerius, Taylor conducts an analysis of the development of Design Art and looks for its origins in the uncanny explorations of surrealism. Offering a critique of Speculative Design, and an examination of the work of designers such as Mathias Bengtsson, whose work involves 'growing' furniture inside computers, Taylor asks what happens when the tangible melts into the datascape and design becomes a question of mobilities. In this way, Moving Objects examines contemporary issues of how we live with artefacts and what design can do.
