Physicians lead. It’s an integral part of what they do. They lead patients, they lead healthcare teams, they lead colleagues, departments, and organizations. But most doctors receive very little training in leadership.Leon E. Moores, MD, DSc, FACS is a neurosurgeon and seasoned healthcare leader who literally “wrote the book” on physician leadership for the U.S. Army. A West Point graduate, Moores became an officer and a surgeon in the Army and recognized how the lack of formal leadership training for doctors impacts physician effectiveness, team performance, and patient outcomes. Along with a team of highly accomplished colleagues, he created the physician leadership development program that has been widely referenced by the U.S. military. Moores now shares that leadership wisdom, and the lessons he has learned through decades of healthcare organization leadership, with physicians everywhere and with all readers passionate about improving healthcare.Ver libro
Climate change is a problem so enormous and complex—with threats so frightening in their implications—that many of us fend off confusion and hopelessness by simply turning away. Meanwhile, with delayed action, missed targets, and increasingly dire reports at the international level, a notion that the crisis is intractable continues to spread. And the proposed solutions can be just as daunting. They often involve jargon about gigatons of carbon and kilowatt-hours of electricity. In a deeply polarized political environment, any sense of the common purpose required to make these work seems to dissolve into denial or paralysis. With all this fear and conflict, the question must be asked: How do we find the tools and the hope we need to tackle such a wickedly difficult issue? In Climate Hope, journalist David Geselbracht blends in-depth research, expert interviews, and on-the-ground reporting in multiple countries, revealing remarkable efforts to identify the causes and impacts of climate change—and devise crucial ways to address them. The scale of the challenge is clear in the range of fields he covers, from glaciology and climate science to law and diplomacy. But in drawing these approaches together, he shares stories of hope, awe, and wonder that encourage us to confront this long-term, world-warping phenomenon with a renewed sense of purpose and possibility.Ver libro
Tele Aadsen met the ocean as a child when her parents traded jobs as veterinarians for a migratory life shared with sea birds, salmon, and fishermen. In the mist of the Tongass rainforest, Tele learned to explore life within endless shades of gray, coming to know firsthand how fine the line between life and death and the precarious balance of sea, land, and sky. She’s spent the four decades since trolling for salmon off Southeast Alaska. In What Water Holds, a series of lyrical essays first shared at Oregon’s FisherPoets Gathering, Tele examines questions of equity, identity, community, the changing climate, and sustainability with loving, detailed attention, revealing the complexities within their many shades of gray. Weaving stories of what lies beneath the surface and the possibilities beyond, What Water Holds speaks to anyone who has fallen under the spell of the sea, struggled to find their own uncharted path, and wrestled with big philosophical questions – in short, anyone seeking to live a full, deeply considered life. “In this beautiful, brave, knowledgeable collection, Aadsen invites us to examine an industry with clear eyes. Her recollections are rich and poignant, and her eye for social critique is unwavering as she lays bare the complexities of fishing life. Gender, death, power, history, relationships, and the natural world all come under her gaze and are shared with ruthless love.” - Lara Messersmith-Glavin, author of Spirit ThingsVer libro
For many people, cockroaches are the most pesky of pests. In this funny and fascinating book, Frank reveals his love and admiration for so-called "nasty" creatures like cockroaches, crickets, and more. He shows us that even seemingly terrifying insects are beautiful in their own way—and essential to all life on Earth. Frank never planned to study cockroaches. But when researching hummingbirds fell through, he switched to cockroach feces—and soon fell in love. Cockroaches are incredible survivors, devoted parents, and adapt to almost any environment. Nischk even answers the age-old question of whether a cockroach would survive a nuclear explosion. After hearing such eye-opening and warm-hearted stories, you'll think twice before stepping on one! From cockroaches to crickets, Nischk travels to Ecuador to record cricket sounds, where he finds jungles bursting with a riot of insect life (including bullet ants whose stings are surprisingly painful). As Nischk tells his (mis)adventures as an entomologist, he shares stories about intriguing insect discoveries, from damselflies who lay eggs deep underwater, to zombie fungi that invade the brains of ants. Brimming with fascinating facts, incredible stories, and unbelievable anecdotes, Of Cockroaches and Crickets will intrigue anyone who has ever loved—or hated!—bugs.Ver libro
