Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.

A Framework for K-12 Science Education and Next Generation Science Standards (NGSS) describe a new vision for science learning and teaching that is catalyzing improvements in science classrooms across the United States. Achieving this new vision will require time, resources, and ongoing commitment from state, district, and school leaders, as well as classroom teachers. Successful implementation of the NGSS will ensure that all K-12 students have high-quality opportunities to learn science. Guide to Implementing the Next Generation Science Standards provides guidance to district and school leaders and teachers charged with developing a plan and implementing the NGSS as they change their curriculum, instruction, professional learning, policies, and assessment to align with the new standards. For each of these elements, this report lays out recommendations for action around key issues and cautions about potential pitfalls. Coordinating changes in these aspects of the education system is challenging. As a foundation for that process, Guide to Implementing the Next Generation Science Standards identifies some overarching principles that should guide the planning and implementation process. The new standards present a vision of science and engineering learning designed to bring these subjects alive for all students, emphasizing the satisfaction of pursuing compelling questions and the joy of discovery and invention. Achieving this vision in all science classrooms will be a major undertaking and will require changes to many aspects of science education. Guide to Implementing the Next Generation Science Standards will be a valuable resource for states, districts, and schools charged with planning and implementing changes, to help them achieve the goal of teaching science for the 21st century.

Car Safety Wars is a gripping history of the hundred-year struggle to improve the safety of American automobiles and save lives on the highways. Described as the “equivalent of war” by the Supreme Court, the battle involved the automobile industry, unsung and long-forgotten safety heroes, at least six US Presidents, a reluctant Congress, new auto technologies, and, most of all, the mindset of the American public: would they demand and be willing to pay for safer cars? The “Car Safety Wars” were at first won by consumers and safety advocates. The major victory was the enactment in 1966 of a ground breaking federal safety law. The safety act was pushed through Congress over the bitter objections of car manufacturers by a major scandal involving General Motors, its private detectives, Ralph Nader, and a gutty cigar-chomping old politician. The act is a success story for government safety regulation. It has cut highway death and injury rates by over seventy percent in the years since its enactment, saving more than two million lives and billions of taxpayer dollars. But the car safety wars have never ended. GM has recently been charged with covering up deadly defects resulting in multiple ignition switch shut offs. Toyota has been fined for not reporting fatal unintended acceleration in many models. Honda and other companies have—for years—sold cars incorporating defective air bags. These current events, suggesting a failure of safety regulation, may serve to warn us that safety laws and agencies created with good intentions can be corrupted and strangled over time. This book suggests ways to avoid this result, but shows that safer cars and highways are a hard road to travel. We are only part of the way home.

“A charming personal account, accompanied by nearly 100 illustrations, that underscores how owls and other birds enrich our lives.”—Kirkus Reviews Winner of the National Outdoor Book Award For a quarter of a century, Tony Angell and his family shared the remarkable experience of closely observing pairs of western screech owls that occupied a nesting box outside the window of their forest home. The journals in which the author recorded his observations, and the captivating drawings he created, form the heart of this compelling book—a personal account of an artist-naturalist’s life with owls. Angell’s extensive illustrations show owls engaged in what owls do—hunting, courting, raising families, and exercising their inquisitive natures—and reveal his immeasurable respect for their secret lives and daunting challenges. Angell discusses the unique characteristics that distinguish owls from other bird species and provides a fascinating overview of the impact owls have had on human culture and thought. He also offers detailed scientific descriptions of the nineteen species of owls found in North America, as well as their close relatives elsewhere. Always emphasizing the interaction of humans and owls, the author affirms the power of these birds to both beguile and inspire. “Endearing…provides a lot of fascinating information about these reclusive creatures.”—The New York Times Book Review “Angell writes (and draws) with the absolute authority of one who has studied, rehabilitated, lived with and loved the animals his whole life.”—The Wall Street Journal “Steeped in the tradition of Alexander Wilson and John James Audubon, it blends taxonomy, ornithology, biogeography and autobiography.”—Times Literary Supplement

It is possible to eliminate death and serious injury from Canada’s roads. In other jurisdictions, the European Union, centres in the United States, and at least one automotive company aim to achieve comparable results as early as 2020. In Canada, though, citizens must turn their thinking on its head and make road safety a national priority. Since the motor vehicle first went into mass production, the driver has taken most of the blame for its failures. In a world where each person’s safety is dependent on a system in which millions of drivers must drive perfectly over billions of hours behind the wheel, failure on a massive scale has been the result. When we neglect the central role of the motor vehicle as a dangerous consumer product, the result is one of the largest human-made means for physically assaulting human beings. It is time for Canadians to embrace internationally recognized ways of thinking and enter an era in which the motor vehicle by-product of human carnage is relegated to history. No Accident examines problems related to road safety and makes recommendations for the way forward. Topics include types of drivers; human-related driving errors related to fatigue, speed, alcohol, and distraction and roads; pedestrians, cyclists, and public transit; road engineering; motor vehicle regulation; auto safety design; and collision-avoidance technologies such as radar and camera-based sensors on vehicles that prevent crashes. This multi-disciplinary study demystifies the world of road safety and provides a road map for the next twenty years.
