Winner of the Believer Book Award The triumphant follow-up collection to The Game of Boxes, winner of the James Laughlin Award Catherine Barnett’s tragicomic third collection, Human Hours, shuttles between a Whitmanian embrace of others and a kind of rapacious solitude. Barnett speaks from the middle of hope and confusion, carrying philosophy into the everyday. Watching a son become a young man, a father become a restless beloved shell, and a country betray its democratic ideals, the speakers try to make sense of such departures. Four lyric essays investigate the essential urge and appeal of questions that are “accursed,” that are limited—and unanswered—by answers. What are we to do with the endangered human hours that remain to us? Across the leaps and swerves of this collection, the fevered mind tries to slow—or at least measure—time with quiet bravura: by counting a lover’s breaths; by remembering a father’s space-age watch; by envisioning the apocalyptic future while bedding down on a hard, cold floor, head resting on a dictionary. Human Hours pulses with the absurd, with humor that accompanies the precariousness of the human condition.

"Drawing on work of Pierre Teilhard de Chardin and modern science, author offers meditations pointing toward a new understanding of Christianity in terms of evolution"--

AN INSTANT NEW YORK TIMES BESTSELLER "Provocative and appealing . . . well worth your extremely limited time." —Barbara Spindel, The Wall Street Journal The average human lifespan is absurdly, insultingly brief. Assuming you live to be eighty, you have just over four thousand weeks. Nobody needs telling there isn’t enough time. We’re obsessed with our lengthening to-do lists, our overfilled inboxes, work-life balance, and the ceaseless battle against distraction; and we’re deluged with advice on becoming more productive and efficient, and “life hacks” to optimize our days. But such techniques often end up making things worse. The sense of anxious hurry grows more intense, and still the most meaningful parts of life seem to lie just beyond the horizon. Still, we rarely make the connection between our daily struggles with time and the ultimate time management problem: the challenge of how best to use our four thousand weeks. Drawing on the insights of both ancient and contemporary philosophers, psychologists, and spiritual teachers, Oliver Burkeman delivers an entertaining, humorous, practical, and ultimately profound guide to time and time management. Rejecting the futile modern fixation on “getting everything done,” Four Thousand Weeks introduces readers to tools for constructing a meaningful life by embracing finitude, showing how many of the unhelpful ways we’ve come to think about time aren’t inescapable, unchanging truths, but choices we’ve made as individuals and as a society—and that we could do things differently.

This report from the Committee on Military Nutrition Research reviews the history of caffeine usage, the metabolism of caffeine, and its physiological effects. The effects of caffeine on physical performance, cognitive function and alertness, and alleviation of sleep deprivation impairments are discussed in light of recent scientific literature. The impact of caffeine consumption on various aspects of health, including cardiovascular disease, reproduction, bone mineral density, and fluid homeostasis are reviewed. The behavioral effects of caffeine are also discussed, including the effect of caffeine on reaction to stress, withdrawal effects, and detrimental effects of high intakes. The amounts of caffeine found to enhance vigilance and reaction time consistently are reviewed and recommendations are made with respect to amounts of caffeine appropriate for maintaining alertness of military personnel during field operations. Recommendations are also provided on the need for appropriate labeling of caffeine-containing supplements, and education of military personnel on the use of these supplements. A brief review of some alternatives to caffeine is also provided.

Advances in Radiation Biology: Relative Radiation Sensitivities of Human Organ Systems, Part III, is the third volume of the series "Relative Radiation Sensitivities of Human Organ Systems." It presents reviews of organ systems not included in the preceding two parts (Advances in Radiation Biology, Volumes 12 and 14). The subject matter contained in the current volume is viewed through the eyes of the radiation therapist. Although the presentations have strong clinical overtones, an effort has been made, wherever possible, also to address the radiobiological bases of radiation sensitivity of organs. The book contains seven chapters and begins with a study on radiation damage to the kidney. This is followed by separate chapters on inherent or intrinsic radiosensitivity of human cells; the impact of brachytherapy (i.e., short-distance radiation treatment using photon radiation) on tumors; and human tissue tolerance to fast neutron radiotherapy. Subsequent chapters deal with normal tissue effects of combined hyperthermia and radiotherapy; the impact of ionizing radiation on the successive stages of human development in utero; and developments in theoretical knowledge and practical applications of ionizing radiations which have taken place in a little less than a century.
