Our Oldest Task

“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.

"General McChrystal is a legendary warrior with a fine eye for enduring lessons about leadership, courage, and consequence." —Tom Brokaw General Stanley McChrystal is widely admired for his hunger to know the truth, his courage to find it, and his humility to listen to those around him. Even as the commanding officer of all U.S. and coalition forces in Afghanistan, he stationed himself forward and frequently went on patrols with his troops to experience their challenges firsthand. In this illuminating New York Times bestseller, McChrystal frankly explores the major episodes and controversies of his career. He describes the many outstanding leaders he served with and the handful of bad leaders he learned not to emulate. And he paints a vivid portrait of how the military establishment turned itself, in one generation, into the adaptive, resilient force that would soon be tested in Iraq, Afghanistan, and the wider War on Terror. "A compelling account of his impressive career." -The Wall Street Journal ' "This is a brilliant book about leadership wrapped inside a fascinating personal narrative." -Walter Isaacson, author of Steve Jobs Stanley McChrystal retired in July 2010 as a four-star general in the U.S. Army. His last assignment was as the commander of the International Security Assistance Force and as the commander of U.S. forces in Afghanistan. He is currently a senior fellow at Yale University's Jackson Institute for Global Affairs and cofounder of the McChrystal Group, a leadership consulting firm. He and his wife, Annie, live in Virginia.

Nowadays, the advent of the wireless Internet and the rapid expanding of novel technologies on the mass market have represented a tremendous stimulus for pushing the development of interactive systems able to encompass support for a larger and larger variety of users, tasks, devices and contexts. In this thesis we present the benefits of using task models in the various steps of the lifecycle of an interactive application. Indeed, we show how they can play an important role in the requirements elicitation phase for example, by requiring precise definition of temporal relationships between the different activities that should be performed, so avoiding any ambiguities. Furthermore, we describe how task models may be exploited in software development beyond early analysis as they can provide valuable information for the design of interactive applications through a number of criteria specifying how to use the data contained in task models to drive the design of the user interface. Additionally, we analyse how they can be used for verification purposes, in order to check some properties of the modelled system (in combination with other models), so improving the level of confidence towards the system, which can be relevant especially in safety-critical contexts. Lastly, we show the benefits that can be gained from using task models in the usability evaluation phase, through a systematic analysis of the impact that the deviations from an expected task plan could have on the quality of the overall system.

The first comprehensive exploration on the subject of older men, Older Men's Lives offers a multidisciplinary portrait of men and their concerns in later life. Using both a life-course and gendered perspective, the contributors to this collection of original articles point out that the image and self-image of men are continuously reconstructed over the life cycle. They examine older men's position in society and the changes wrought in their status and roles over time. Their relationship with their spouses, children, grandchildren, and friends are also explored, as are policy implications of a gendered, life-cycle view of masculinity. This volume also discusses faith development in older men, masculinity identity from work to retirement, older men's sexuality, and older men's friendship patterns. Older Men's Lives will be of interest to professionals and students interested in gender, men's studies, gerontology, and sociology. "This book begins to remedy the lack of information and provides data and research on aging men. . . .The strength of this book is the specificity of its focus. By focusing solely on male concerns the book is able to identify issues in the male aging process and discuss them on their own terms rather than simply as a contrast to females." --Clinical Gerontologist

Peter Marsh and Mark Doel's new book is a radical departure from traditional literature on social work methods. The main reference point is the voice of practitioners, service users and carers, as researched and developed by the authors over twenty years.

Multitasking refers to performance of multiple tasks. The most prominent types of multitasking are situations including either temporal overlap of the execution of multiple tasks (i.e., dual tasking) or executing multiple tasks in varying sequences (i.e., task switching). In the literature, numerous attempts have aimed at theorizing about the specific characteristics of executive functions that control interference between simultaneously and/or sequentially active component of task-sets in these situations. However, these approaches have been rather vague regarding explanatory concepts (e.g., task-set inhibition, preparation, shielding, capacity limitation), widely lacking theories on detailed mechanisms and/ or empirical evidence for specific subcomponents. The present research topic aims at providing a selection of contributions on the details of executive functioning in dual-task and task switching situations. The contributions specify these executive functions by focusing on (1) fractionating assumed mechanisms into constituent subcomponents, (2) their variations by age or in clinical subpopulations, and/ or (3) their plasticity as a response to practice and training.
