Hitting the Brakes: Engineering Design and the Production of Knowledge
In Hitting the Brakes, Ann Johnson illuminates the complex social, historical, and cultural dynamics of engineering design, in which knowledge communities come together to produce new products and knowledge. Using the development of antilock braking systems for passenger cars as a case study, Johnson shows that the path to invention is neither linear nor top-down, but highly complicated and unpredictable. Individuals, corporations, university research centers, and government organizations informally coalesce around a design problem that is continually refined and redefined as paths of development are proposed and discarded, participants come and go, and information circulates within the knowledge community. Detours, dead ends, and failures feed back into the developmental process, so that the end design represents the convergence of multiple, diverse streams of knowledge.The development of antilock braking systems (ABS) provides an ideal case study for examining the process of engineering design because it presented an array of common difficulties faced by engineers in research and development. ABS did not develop predictably. Research and development took place in both the public and private sectors and involved individuals working in different disciplines, languages, institutions, and corporations. Johnson traces ABS development from its first patents in the 1930s to the successful 1978 market introduction of integrated ABS by Daimler and Bosch. She examines how a knowledge community first formed around understanding the phenomenon of skidding, before it turned its attention to building instruments to measure, model, and prevent cars' wheels from locking up. While corporations' accounts of ABS development often present a simple linear story, Hitting the Brakes describes the full social and cognitive complexity and context of engineering design.

Dragonflies and Damselflies in Your Pocket: A Guide to the Odonates of the Upper Midwest
Just as more and more people enjoy watching birds and butterflies, watching the many shimmering dragonflies and damselflies - collectively called odonates, from Odonata, the name of this order of aquatic insects - has become a popular pastime. Now Dragonflies and Damselflies in Your Pocket introduces us to 50 of the showiest odonates of the Upper Midwest. Ann Johnson's text is clear and informative and her photographs are stunning; it is impossible to look at them without wanting to head out for the nearest stream and search for the living insects. In addition to providing useful general information about broad-winged damsels, spreadwings, pond damsels, darners, clubtails, cruisers, emeralds, and skimmers, she includes common and scientific names, sizes, general flight seasons, and the best habitats in which to find each species: rocky rivers, wetlands, ponds, still waters, and so on. With their extremely large eyes, elongated transparent wings, long and slender abdomens, and prehensile extendible jaws, dragonflies and damselflies are efficient hunters and quick, darting fliers. Their beauty and their behavior make them delightful subjects for birdwatchers and other nature lovers. Dragonflies and Damselflies in Your Pocket will greatly enhance your appreciation of these winged marvels.
