Charles Franklin Kettering (1876–1958) was an inventor well-known during his lifetime, earning 186 US patents. His most notable invention was the automobile electric starter which put an end to the difficult and dangerous practice of hand cranking. Some of his later work—leaded gasoline and Freon—was controversial and had unintended environmental consequences. He led both the National Inventors' Council and the National Patent Planning Commission. Kettering characterized himself as “just a plain old inventor,” but he was a shrewd businessman. He is still remembered fondly by scientists and staff at the General Motors R&D Center he founded in 1920. 相似文献

Abstract Roger Taylor, in his response to my paper, may unwittingly have provided us with the answer to why Antoine Claudet distanced himself so firmly from the drawn out machinations and negotiations that led in January 1853 to the formation of what is now the Royal Photographic Society. It was snobbery. Taylor highlights the social chasm that existed between those in trade and those in polite society in the middle of the nineteenth century. ‘It is difficult to appreciate’, he reminds us, ‘just how conspicuously separate the two photographic communities (daguerreotype and calotype) were in the 1850s’. 相似文献

Several amateur photographers lived and worked in the Coal Branch, a series of mining communities in the eastern foothills of the Canadian Rocky Mountains in Alberta. These communities were transient and very isolated from the rest of the province. Among the photographers working there were Allan Godby and Charles Lee, whose photographs are housed at the Provincial Archives of Alberta. The photographs of Godby and Lee present a unique record of life in the Coal Branch and provide particular insight into the social structures of that community as well as offering a mediated visual document of imposed settlement in pristine wilderness. 相似文献

Operating between the obscene and methods of estrangement and displacement, parrhesia-stases interrogates the agendas of aesthetics present in repulsiveness, condemnation and punishment. François Roche and Camille LacadÉe here present a body of work by their Bangkok-based practice New-Territories/M4, which speculates on the ramifications of architecture as a paradigm of disobedience. Deeply rooted in Michel Foucault's proposal for a re-evaluation of an ethico-political approach, the work investigates an alternative architectural position that utilises strategies of transfiguration to provoke pathological behaviours. 相似文献

埃利奥特是美国近现代史上典型的教育领导者之一.国内学者较为全面地研究了他一生中所从事的教育实践,但是埃利奥特从事教育实践的原因与动力仍有待进一步探究.在美国内战之后,大多数中上层人士都关注如何重塑民族-国家的问题,各个教派与政党相互勾结,争相成为“新美国民族”的引路人.美国大到各个州的政党竞选,小到各个县郡的学校领导人的选举,都浸染在这种氛围里面,学院(大学)几乎成了各个教派信徒的培养基地.在这种环境之下,埃利奥特倡导学院(大学)教育应由民主而非教派决定,应摒弃党派之见,共同为美国民族-国家共同体服务,培育未来的参政议政精英而非各个教派的信徒.到了19世纪末,由于自由主义导致美国社会弊端日益凸显,埃利奥特的教育思想也有相应转变. 相似文献
