Returns to Higher Education in 21 OECD Countries: The impact of economic and university policies. – We present new estimates of the private internal rate of return (IRR) to Higher Education (HE) in 21 OECD countries. In 2001 the IRR varied considerably across countries, ranging from 4 percent for women in Italy (5 percent for men in Spain) to 14 percent in Ireland. IRR are relatively homogeneous across gender. At 6¼ percent the IRR for Germany falls short of the OECD average (8½ percent). The largest contributor to benefits from HE is the educational wage premium; the largest contributor to costs is foregone income while studying. Cross-country differences in IRR are driven by differences in the wage premium (27 percent in Spain versus 91 percent in Hungary and the United States), in the duration of HE, the marginal tax rate, and direct costs of HE. We then simulate the effect of policy reforms on the IRR. An increase in tuition fees equivalent to 15 percent of average national income would reduce the IRR by 0.8 to 1.6 percentage points (Germany: 1.1 percent). Shortening the duration of studies by 10 percent and reducing the progressiveness of the income tax schedule would compensate for the fall in the IRR.  相似文献

The aim of this study was to determine what visual information expert soccer players encode when they are asked to make a decision. We used a repetition-priming paradigm to test the hypothesis that experts encode a soccer pattern's structure independently of the players' physical characteristics (i.e., posture and morphology). The participants were given either realistic (digital photos) or abstract (three-dimensional schematic representations) soccer game patterns. The results showed that the experts benefited from priming effects regardless of how abstract the stimuli were. This suggests that an abstract representation of a realistic pattern (i.e., one that does not include visual information related to the players'physical characteristics) is sufficient to activate experts'specific knowledge during decision making. These results seem to show that expert soccer players encode and store abstract representations of visual patterns in memory.  相似文献

Abstract

The aim of this study was to compare the somersaulting techniques used in the 16 highest-scoring and 16 lowest-scoring Roche vaults. Our hypothesis was that the gymnasts performing the highest-scoring Roche vaults would demonstrate a better technique than those performing the lowest-scoring Roche vaults while on the horse (pushing off the horse more effectively), somersaulting (executing most of the required somersaults higher in flight), and landing (showing a greater control). A 16-mm motion picture camera, operating at 100 Hz, recorded the vaults during the official competition. The two-dimensional direct linear transformation was used for spatial reconstruction. The results of t-tests (P < 0.05) indicated that, compared with the low-scoring gymnasts, the high-scoring gymnasts had: (1) greater height of body centre of mass and a more fully extended body position at the horse take-off; (2) greater height of body centre of mass at the peak of post-flight, knee release, and touchdown on the mat; (3) greater horizontal and vertical displacements of body centre of mass, greater somersaulting rotation, and longer time from the knee release to mat touchdown; and (d) markedly smaller landing point deductions. In conclusion, a successful Roche vault is likely when the focus is on: (a) leaving the horse with a large vertical velocity in an extended body position to achieve a high trajectory of centre of mass by first extending the legs, then immediately pushing off the horse vigorously, using the muscles of the upper extremity; (b) grasping the knees immediately after the take-off from the horse, achieving the tightly tucked body position early during the ascent to the peak, and completing two-thirds of the required somersaults at a great height; (c) releasing the knees and extending the body above the top level of the horse; and (d) contacting the mat with a high body centre of mass position.  相似文献

The relationship between personality dimensions, measured with the Multicultural Personality Questionnaire (MPQ), and foreign language mastery were studied in a Dutch-based multinational company in the agricultural sector. In a survey, differences were studied between internal and external stakeholders to determine whether MPQ dimensions and language mastery allow us to discriminate between them. The internal stakeholders were divided into international and non-international employees; external stakeholders were the business contacts of the international employees (clients and business partners based or working abroad). The international employees were found to be more open-minded and flexible than the non-international employees, and the former group was found to be more emotionally stable than the group of business contacts. On average, the international employees reported speaking one foreign language more than both other groups. Also, the number of foreign languages correlated with the multicultural personality dimensions open-mindedness and emotional stability. It is concluded that emotional stability, open-mindedness, and the number of spoken foreign languages are to some extent predictive of differences between the various stakeholders distinguished in this sample.  相似文献

This paper summarises the debate on modularisation in initial vocational training provisions in Germany in the context of the German 'dual system'. This system has been increasingly criticised in recent years and the paper describes the on-going discussion regarding potential strategies for the modernisation of this system. The paper then introduces three different concepts of modularisation in training provisions that have emerged from the recent debate in Germany. They are each evaluated in terms of their potential application to the German training framework. Finally, a potential strategy for the modularisation of initial training in Germany is proposed. It draws on research regarding modules and units in training in other European countries and shows how it might be possible to embed the concept of modularisation within the pre-existing training frameworks in the German context.  相似文献

自20世纪50年代起欧盟的教育与培训政策,可以分为<罗马条约>后时期、<马斯特里赫特条约)后时期以及<里斯本总结>后时期三个时期,不同时期内的欧盟教育培训政策的法律基础、指导原则、主要执行方式对成员国的教育和培训系统产生不同影响.50年来,在经济利益的驱动下,欧盟在教育与职业培训方面的职能通过一系列的条约与政府间协议得到了不断的增强.但一些当前的迹象也显示,欧盟各成员国考虑到各自的利益,执行欧盟教育培训政策的步调并不一致.  相似文献
