Planning for sustainable mobility is a complex and demanding task and the knowledge of how to trade off multiple, often conflicting, goals is not entirely clear. One of the most contentious and confounding issues in the context of urban planning has been, and continues to be, the place of the automobile within the evolving sustainable mobility paradigm. The recent emergence of strong policy and planning support for the introduction of electric vehicles raises thorny questions as to whether or not this development will be complementary to, or conflicting with, other sustainable mobility planning goals, such as the pursuit of compact cities, restrictions on automobiles, promotion of walking and bicycling, and support for public transport. The results of a recent pilot study conducted in the Reykjavik city region suggest that a strategy of provision for electric vehicles on a large scale may represent a continuation of the dominant transport engineering approach, drawing scarce financial and institutional resources away from path-breaking measures such as the efforts to create denser development patterns and promote non-motorized and public forms of transport. 相似文献

This article presents a case study of the rise of Pfizer as a leading pharmaceutical company, with a focus on changing relationships between manufacturing technology and R&D between the mid 1940s and the mid 1960s. Pfizer first moved into pharmaceuticals through participation in the US government's penicillin effort during World War II. The company had expertise in deep tank, biological fermentation for the production of chemicals that it adapted to the manufacture of penicillin. Having greatly expanded its biological manufacturing capacity to meet state needs, Pfizer adopted an R&D program to find new microbial antibiotics suited to its manufacturing technology after the war ended. Pfizer's successes in this antibiotic era established the firm as a major pharmaceutical company. In looking to larger commercial markets for drugs, Pfizer, like its competitors, pursued medicines for chronic diseases rather than acute infections. For this pursuit, in the 1950s and 1960s, Pfizer transformed itself into a chemistry‐orientated pharmaceutical firm by reorienting its R&D toward chemistry. This led to a growing divergence between R&D and manufacturing and the eventual replacement of biological manufacturing with chemical manufacturing. The article explores the changing trajectories of R&D and manufacturing at Pfizer, their shifting positions within the firm, and the consequences of these changes and shifts for the firm's strategy and organization. 相似文献

William Thornton, MD, was a polymath who designed the Capitol of the U.S. Capital and the Octagon House, present home of the American Institute of Architecture. He was the founding director of the U.S. Patent Office. His collected papers, which are now preserved at the U.S. Library of Congress, though pruned by the wife who lived almost 40 years after him, are extensive and include comments on science, education, slavery, and politics. His views on sleep and dreaming and his concepts of resuscitation are reviewed as the opinions of an educated man early in the nineteenth century. 相似文献
