Ed Marko redefines what it means to be not only an auto mechanic but also a person who is blind. At the age of 20 years, he lost his sight from a degenerative disease called infantile glaucoma. However, he has surpassed what we traditionally think of as the capabilities of blind people. Now in his late 60s, he was once a rehabilitation counsellor, but he also enjoyed working on cars. Then he decided to open his own shop, Community Car Care, in Columbus, Ohio. Plan F , a 27-minute documentary awarded the 2007 Oxford International Film Festival Award in cinematography and nominated for best short documentary at the Southern Winds Film Festival, takes us through a day in Ed's life as we watch him work on cars and interact with his partner Brad and his cat. Ed teaches us that one does not need to see to work on cars as he uses his fingers and tongue to manipulate bolts, nuts and bearings. The ways Ed navigates the auto shop demonstrate how he approaches life. If Plan A does not work, he moves on to Plan B. Flexibility and a sense of humour allow him to switch to a new plan when the first one does not work out. In this review of Plan F , we begin with summaries of the nine major scenes of the documentary, followed by reviews by a blind and a sighted person. The piece concludes with comments from the director.  相似文献

Workplace learning is increasingly central to the international lifelong learning agenda but has made limited contributions to full-time vocational education in England during the last 30 years. A more central role is envisaged within the technical education proposed by the 2016 Sainsbury Review and Post-16 Skills Plan, with access to work placements dominating discussion of policy implementation. A multicase study of workplace learning among post-16 students in England on current ‘study programmes’ was mapped to four of the technical routes designated by the Sainsbury Review and Skills Plan, using documentary, observation and interview data. The study drew on theorisation of the workplace as the site of situated or incidental learning, whilst noting that its opportunities are differentially allocated according to organisational or personal differences, in ways that have particular implications for young people on placements. Whilst access to more advanced learning opportunities was secured through planned, collaborative approaches, reliance on incidental learning offered more routinised experiences to students less prepared for autonomous learning. The study indicates that questions of access, knowledge and pedagogy remain to be addressed if plans for ‘technical education’ in England are to provide meaningful learning opportunities and support transitions to fulfilling work.  相似文献

Finding all occurrences of a twig pattern is a core operation of extensible markup language (XML) query processing. Holistic twig join algorithms, which avoid a large number of intermediate results, represent the state-of-the-art algorithms. However, ordered XML twig join is mentioned rarely in the literature and previous algorithms developed in attempts to solve the problem of ordered twig pattern (OTP) matching have poor performance. In this paper, we first propose a novel children linked stacks encoding scheme to represent compactly the partial ordered twig join results. Based on this encoding scheme and extended Dewey, we design a novel holistic OTP matching algorithm, called OTJFast, which needs only to access the labels of the leaf query nodes. Furthermore, we propose a new algorithm, named OTJFaster, incorporating three effective optimization rules to avoid unnecessary computations. This works well on available indices (such as B~-tree), skipping useless elements. Thus, not only is disk access reduced greatly, but also many unnecessary computations are avoided. Finally, our extensive experiments over both real and synthetic datasets indicate that our algorithms are superior to previous approaches.  相似文献

随着教育现代化发展的日新月异,教学内容已经跟不上教育信息化发展的步伐,因而难以满足现代化教育对教学信息资源及教学管理的实时需求。基于现代化教育背景,从教学管理及教育信息资源共享角度出发,充分考虑教育信息资源共享的出发点与归宿点,提出构建教育信息资源共享网络框架,并对校园局部教育资源共享的网络框架示例进行了深入研究,以期为现代教育信息资源共享管理探索出新的路径,并为提高现代教育水平作出积极贡献。  相似文献
