How migratory birds can navigate home from their wintering grounds to their breeding sites over hundreds and thousands of kilometres has been an admired mystery over more than a century. Profound advances towards a solution of this problem have been achieved with a model bird, the homing pigeon. This monograph summarizes our current knowledge about pigeon homing, about the birds' application of a sun compass and a magnetic compass, of a visual topographical map within a familiar area and -- most surprisingly -- of an olfactory map using atmospheric chemosignals as indicators of position in distant unfamiliar areas.
The Intellectual Struggle for Florence is an analysis of the ideology that developed in Florence with the rise of the Medici, during the early fifteenth century, the period long recognized as the most formative of the early Renaissance. Instead of simply describing early Renaissance ideas, this volume attempts to relate these ideas to specific social and political conflicts of the fifteenth century, and specifically to the development of the Medici regime. It first shows how the Medici party came to be viewed as fundamentally different from their opponents, the "oligarchs," then explores the intellectual world of these oligarchs (the "traditional culture"). As political conflicts sharpened, some humanists (Leonardo Bruni and Francesco Filelfo) with close ties to oligarchy still attempted to enrich traditional culture with classical learning, while others, such as Niccolo Niccoli and Poggio Bracciolini, rejected tradition outright and created a new ideology for the Medici party. What is striking is the extent to which Niccoli and Poggio were able to turn a Latin or classical culture into a "popular culture," and how the culture of the vernacular remained traditional and oligarchic.
With the vision that machines can be rendered smarter, we have witnessed for more than a decade tremendous engineering efforts to implement intelligent sys tems. These attempts involve emulating human reasoning, and researchers have tried to model such reasoning from various points of view. But we know precious little about human reasoning processes, learning mechanisms and the like, and in particular about reasoning with limited, imprecise knowledge. In a sense, intelligent systems are machines which use the most general form of human knowledge together with human reasoning capability to reach decisions. Thus the general problem of reasoning with knowledge is the core of design methodology....
This title is part of UC Press's Voices Revived program, which commemorates University of California Press’s mission to seek out and cultivate the brightest minds and give them voice, reach, and impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand technology. This title was originally published in 1977.
Gulf War and Health, Volume 2, is the second in a series of congressionally-mandated studies by the Institute of Medicine that provides a comprehensive assessment of the available scientific literature on potential health effects of exposure to certain biological, chemical, and environmental agents associated with the Gulf War. In this second study, the committee evaluated the published, peer-reviewed literature on exposure to insecticides and solvents thought to have been present during the 1990-1991 war. Because little information exists on actual exposure levels â€" a critical factor when assessing health effects â€" the committee could not draw specific conclusions about the health problems of Gulf War veterans. However, the study found some evidence, although usually limited, to link specific long-term health outcomes with exposure to certain insecticides and solvents. The next phase of the series will examine the literature on potential health effects associated with exposure to selected environmental pollutants and particulates, such as oil-well fires and jet fuels.
