In the 1970s and 1980s Dutch farmers replaced their dual-purpose Friesian cows with Holsteins, a highly specialized American dairy breed. The changeover was related to a major turnabout in breeding practices that involved the adoption of quantitative genetics. Dutch commercial breeders had long resisted the quantitative approach to breeding that scientists had been recommending since World War II. After about 1970, however, they gave up their resistance: the art of breeding, it was said, finally became a science. In historical overviews this turnabout is seen as part of what is called the "modernization project" in Dutch agriculture that the government instigated after the war. Economic developments are assumed to have necessitated this project, and specialization of production is seen as a natural consequence. This essay argues that the idea that the art of breeding was turned into a science is to a certain extent misleading. Furthermore, it aims to show that economic pressures and government policies cannot adequately explain the turn toward Holsteins. A better understanding can be obtained by framing the Holsteinization process as the result of a changeover in breeding culture--that is, in the ensemble of shared convictions, beliefs, conventions, methods, practices, and the like that characterized practical cattle breeding and that involved scientific, technical, economic, aesthetic, normative, and commercial considerations. 相似文献

Religious education at school should be more than just the acquisition of knowledge. It should not only provide cognitive facts on how religious people act according to their moral and religious convictions, but also on how learners can gain as much profit as possible from these facts in order to build their own identity as religious ‘tourists’. Good religious education challenges them also to become ‘pilgrims’ and to allow the ‘slow questions’ of religion to enter into their own life, in all their vulnerability and provisionality. This paper discusses the recent orientation towards religious experience in religious didactics in Western Europe and makes out a case for a mystagogical‐communicative or ‘narthical’ approach to religious learning. This argument is presented against the background of individualisation, pluralisation and detraditionalisation of religion, which is the typical context for young people in their search for meaning today. 相似文献

Tandem cycling enables visually impaired athletes to compete in cycling in the Paralympics. Tandem aerodynamics can be analysed by track measurements, wind-tunnel experiments and numerical simulations with computational fluid dynamics (CFD). However, the proximity of the pilot (front) and the stoker (rear) and the associated strong aerodynamic interactions between both athletes present substantial challenges for CFD simulations, the results of which can be very sensitive to computational parameters such as grid topology and turbulence model. To the best of our knowledge, this paper presents the first CFD and wind-tunnel investigation on tandem cycling aerodynamics. The study analyses the influence of the CFD grid topology and the turbulence model on the aerodynamic forces on pilot and stoker and compares the results with wind-tunnel measurements. It is shown that certain combinations of grid topology and turbulence model give trends that are opposite to those shown by other combinations. Indeed, some combinations provide counter-intuitive drag outcomes with the stoker experiencing a drag force up to 28% greater than the pilot. Furthermore, the application of a blockage correction for two athlete bodies in close proximity is investigated. Based on a large number of CFD simulations and validation with wind-tunnel measurements, this paper provides guidelines for the accurate CFD simulation of tandem aerodynamics. 相似文献

Abstract Universities experience increasing difficulty in staffing their academic positions. Attracting and retaining highly qualified employees is a general problem that has received much attention in recent HRM literature. But several authors have claimed that the academic career has lost much of its attractiveness. This paper presents seven levers that universities may use to enhance their recruitment and retention power on a difficult job market. Suggestions are made based on experience from innovative organisations, both universities and business organisations. Special attention is given to the creation of multiple and flexible career paths within academia. We contend that a successful application of these suggestions will require major cultural and institutional change at universities. 相似文献

This paper refers to the dynamic approach to school improvement (DASI) which attempts to contribute to the merging of educational effectiveness research and school improvement. The main underlying assumptions and the implementation phases of DASI are discussed. Moreover, a study aiming to compare the impact of DASI in helping schools to reduce bullying is presented. The results reveal that DASI has a stronger impact on improving school factors and reducing bullying than other approaches to school improvement. Suggestions for further research investigating the sustainability of DASI on school effectiveness are provided and policy implications are drawn. 相似文献
