For the past few years a discussion has been going on about the specific skills and knowledge a complete engineer should possess. Apart form this discussion, a separate debate has focused on the content of an engineer's education. This article is a combination of two joint papers (De Graaff and Ravesteijn 2000, Ravesteijn and De Graaff 2000) bearing on these respective subjects, presented by the authors at the SEFI 2000 conference in Paris. The demands from industry that engineers of the future will have to meet are summarized and related to characteristics of modern training methods. It is argued that a new view on the content of the engineer's education implies, at least to a certain extent, a new set of educational tools.  相似文献

In this paper we propose and test an evolutionary model of stylistic innovation, that is the change in the aesthetic and symbolic elements of products and services. Style is an increasingly relevant phenomenon in many industries and our goal is to develop a model of how styles get introduced and adopted. We build on existent literature on technological change to frame the dynamics of how style changes across time. In the model we propose, companies face periods of ferment with relevant stylistic variations and periods of convergence on a single trend—that is the stylistic convergent design versus the technologic dominant design. We identify the drivers of convergence in stylistic innovation. We test the model with a longitudinal empirical study (1984-2002) in the fine fashion industry, explaining the main differences between a stylistic and a technological evolutionary model.  相似文献

For this study, information on Who Bullies Who was collected from 54 school classes with 918 children (M age = 11) and 13,606 dyadic relations. Bullying and victimization were viewed separately from the point of view of the bully and the victim. The two perspectives were highly complementary. The probability of a bully-victim relationship was higher if the bully was more dominant than the victim, and if the victim was more vulnerable than the bully and more rejected by the class. In a bully-victim dyad, boys were more often the bullies. There was no finding of sex effect for victimization. Liking reduced and disliking increased the probability of a bully-victim relationship.  相似文献

This study explores the views and experiences of 12 young people with autism spectrum disorder (ASD) in transition to post-16 education and employment, in light of the changes introduced by the new special educational needs and disability (SEND) legislation in England. The extension of provision until the age of 25, and the introduction of person-centred education, health and care (EHC) plans, have given a significant place to the views of young people with SEND and their families. The views, wishes and aspirations of young people must be captured in the newly developed plans, reflecting the statutory requirement for local authorities to systematically record these in a biopsychosocial way, focusing on participation and well-being. Twelve semi-structured interviews were conducted with young people with ASD attending specialist settings or receiving specialist support under the new EHC plans. These were analysed inductively, through thematic analysis. The findings suggest that at the time of transition, young people with ASD want to become increasingly more independent, present ambivalent feelings about their future and acknowledge the relevance of support systems in their lives. Implications for practice and future research are discussed, in light of the new English policy context.  相似文献
