“This is a book about nature and culture,” Eric T. Freyfogle writes, “about our place and plight on earth, and the nagging challenges we face in living on it in ways that might endure.” Challenges, he says, we are clearly failing to meet. Harking back to a key phrase from the essays of eminent American conservationist Aldo Leopold, Our Oldest Task spins together lessons from history and philosophy, the life sciences and politics, economics and cultural studies in a personal, erudite quest to understand how we might live on—and in accord with—the land. Passionate and pragmatic, extraordinarily well read and eloquent, Freyfogle details a host of forces that have produced our self-defeating ethos of human exceptionalism. It is this outlook, he argues, not a lack of scientific knowledge or inadequate technology, that is the primary cause of our ecological predicament. Seeking to comprehend both the multifaceted complexity of contemporary environmental problems and the zeitgeist as it unfolds, Freyfogle explores such diverse topics as morality, the nature of reality (and the reality of nature), animal welfare, social justice movements, and market politics. The result is a learned and inspiring rallying cry to achieve balance, a call to use our knowledge to more accurately identify the dividing line between living in and on the world and destruction. “To use nature,” Freyfogle writes, “but not to abuse it.”

A look at the extraordinary ways the brain turns thoughts into actions—and how this shapes our everyday lives Why is it hard to text and drive at the same time? How do you resist eating that extra piece of cake? Why does staring at a tax form feel mentally exhausting? Why can your child expertly fix the computer and yet still forget to put on a coat? From making a cup of coffee to buying a house to changing the world around them, humans are uniquely able to execute necessary actions. How do we do it? Or in other words, how do our brains get things done? In On Task, cognitive neuroscientist David Badre presents the first authoritative introduction to the neuroscience of cognitive control—the remarkable ways that our brains devise sophisticated actions to achieve our goals. We barely notice this routine part of our lives. Yet, cognitive control, also known as executive function, is an astonishing phenomenon that has a profound impact on our well-being. Drawing on cutting-edge research, vivid clinical case studies, and examples from daily life, Badre sheds light on the evolution and inner workings of cognitive control. He examines issues from multitasking and willpower to habitual errors and bad decision making, as well as what happens as our brains develop in childhood and change as we age—and what happens when cognitive control breaks down. Ultimately, Badre shows that cognitive control affects just about everything we do. A revelatory look at how billions of neurons collectively translate abstract ideas into concrete plans, On Task offers an eye-opening investigation into the brain’s critical role in human behavior.

"An unusually strong collection of essays ...the scholarship is impeccable."---Gaines M. Foster, Louisiana State University, Baton Rouge --

It is well recognised that classroom teaching is highly complex and that teachers must navigate and negotiate myriad interactions just within a lesson in order to manage the learning opportunities of their students. What is less well recognised is precisely how these interactions are managed in real time during actual classroom interactions. This book is designed as an original, close-up account of processes by which children learn to become school learners in their first year of school, unpacking some of the recognised complexity of busy classrooms to hone in on what teachers and children do and how learning takes place. Using the tools of conversation analysis, the authors unpack a range of pedagogical interactions between teachers and children during normal class, focusing on procedural instructions and the outcomes of instructed activities. By including transcripts of recordings of classes in schools located in diverse communities, it is possible to see which aspects of classroom interaction may be impacted by external factors, such as children’s language or cultural background, and which aspects are applicable regardless of such factors. The chapters examine teacher instructions and children’s behaviour during instructions and during task performance in whole-class and small-group interactions. Effective Task Instruction in the First Year of School brings forward a much-needed wealth of knowledge into how to teach children in the first year of schooling and beyond in a way that is accessible for practising teachers, student teachers as well as education researchers.

A guide to forming and managing effective task forces.

This book focuses on the theoretical and practical aspects of parallel programming systems for today's high performance multi-core processors and discusses the efficient implementation of key algorithms needed to implement parallel programming models. Such implementations need to take into account the specific architectural aspects of the underlying computer architecture and the features offered by the execution environment. This book briefly reviews key concepts of modern computer architecture, focusing particularly on the performance of parallel codes as well as the relevant concepts in parallel programming models. The book then turns towards the fundamental algorithms used to implement the parallel programming models and discusses how they interact with modern processors. While the book will focus on the general mechanisms, we will mostly use the Intel processor architecture to exemplify the implementation concepts discussed but will present other processor architectures where appropriate. All algorithms and concepts are discussed in an easy to understand way with many illustrative examples, figures, and source code fragments. The target audience of the book is students in Computer Science who are studying compiler construction, parallel programming, or programming systems. Software developers who have an interest in the core algorithms used to implement a parallel runtime system, or who need to educate themselves for projects that require the algorithms and concepts discussed in this book will also benefit from reading it.
