Over the past few decades there has been increased interest in how students and teachers think and learn about negative numbers from a variety of perspectives. In particular, there has been debate about when integers should be taught and how to teach them to best support students’ learning. This book brings together recent work from researchers to illuminate the state of our understanding about issues related to integer addition and subtraction with a goal of highlighting how the variety of perspectives support each other or contribute to the field in unique ways. In particular, this book focuses on three main areas of integer work: students’ thinking, models and metaphors, and teachers’ thinking. Each chapter highlights a theoretically guided study centered on integer addition and subtraction. Internationally known scholars help connect the perspectives and offer additional insights through section commentaries. This book is an invaluable resource to those who are interested in mathematics education and numerical thinking.
The book addresses the impact of ambient intelligence, particularly its user-centric context-awareness requirement on data management strategies and solutions. Techniques of conceptualizing, capturing, protecting, modelling, and querying context information, as well as context-aware data management application are discussed, making the book is an essential reference for computer scientists, information scientists and industrial engineers.
In this sequel to Fugitive Days, Ayers charts his life after the Weather Underground, when he becomes the GOP’s flaunted “domestic terrorist,” a “public enemy.” Labeled a "domestic terrorist" by the McCain campaign in 2008 and used by the radical right in an attempt to castigate Obama for "pallin' around with terrorists," Bill Ayers is in fact a dedicated teacher, father, and social justice advocate with a sharp memory and even sharper wit. Public Enemy tells his story from the moment he and his wife, Bernardine Dohrn, emerged from years on the run and rebuilt their lives as public figures, often celebrated for their community work and much hated by the radical right. In the face o...
Information and communication technologies have transformed the dynamics of contention in contemporary society. Social networks such as Facebook and Twitter, and devices such as smartphones have increasingly played a central role in facilitating and mobilizing social movements throughout different parts of the world. Concurrently, the same technologies have been taken up by public authorities (including security agencies and the police) and have been used as surveillance tools to monitor and suppress the activities of certain demonstrators. This book explores the complex and contradictory relationships between communication and information technologies and social movements by drawing on different case studies from around the world. The contributions analyse how new communication and information technologies impact the way protests are carried out and controlled in the current information age. The authors focus on recent events that date from the Arab Spring onwards and pose questions regarding the future of protests, surveillance and digital landscapes.
