In recent years, there has been a growing interest in white matter anatomy of the human brain. With advances in brain imaging techniques, the significance of white matter integrity for brain function has been demonstrated in various neurological and psychiatric disorders. As the demand for interpretation of clinical and imaging data on white matter increases, the needs for white matter anatomy education are changing. Because cross‐sectional images and formalin‐fixed brain specimens are often insufficient in visualizing the complexity of three‐dimensional (3D) white matter anatomy, obtaining a comprehensible conception of fiber tract morphology can be difficult. Fiber dissection is a technique that allows isolation of whole fiber pathways, revealing 3D structural and functional relationships of white matter in the human brain. In this study, we describe the use of fiber dissection in combination with plastination to obtain durable and easy to use 3D white matter specimens that do not require special care or conditions. The specimens can be used as a tool in teaching white matter anatomy and structural connectivity. We included four human brains and show a series of white matter specimens of both cerebrum and cerebellum focusing on the cerebellar nuclei and associated white matter tracts, as these are especially difficult to visualize in two‐dimensional specimens and demonstrate preservation of detailed human anatomy. Finally, we describe how the integration of white matter specimens with radiological information of new brain imaging techniques such as diffusion tensor imaging tractography can be used in teaching modern neuroanatomy with emphasis on structural connectivity.

Predicting multicultural effectiveness of international students: the Multicultural Personality Questionnaire     

Jan Pieter Van Oudenhoven  Karen I. Van der Zee 《Int J Intercult Relat》2002,26(6)

The present study considered the reliability and validity of the 78-item revised version of the Multicultural Personality Questionnaire, a multidimensional instrument aimed at measuring multicultural effectiveness of expatriate employees and students. The questionnaire includes scales for cultural empathy, open-mindedness, emotional stability, social initiative and flexibility. Participants were native and foreign students of an international business school (N=171) in the Netherlands. The MPQ scales appeared to be more strongly predictive of adjustment of international students as compared to native students. Moreover, the instrument was able to explain variance in students’ adjustment beyond self-efficacy.  相似文献

The Virtue Approach to Moral Education: Some Conceptual Clarifications     

Jan W. Steutel 《Journal of Philosophy of Education》1997,31(3):395-407

There is a lot of talking and writing on virtues and education nowadays. In spite of this, a clear and convincing account of the defining characteristics of the virtue approach to moral education is still lacking. This paper suggests and discusses three different definitions of such an approach. With reference to each definition it is examined whether the virtue approach can be distinguished from other main perspectives on moral education, in particular from the so-called cognitive-developmental approach (including the just community approach). It is argued that only the definition that refers to an ethics of virtue will have the required differentiating capacity. Consequently, only on the basis of this definition can the virtue approach be regarded as a qualitatively new development in research on moral education.  相似文献   

>UNIVERSITIES,COLLEGES AND OTHERS: DIVERSITY OF STRUCTURES FOR HIGHER EDUCATION ‐ REPORT ON THE MULTILATERAL WORKSHOP     

Jan Fridthjof Bernt 《Higher Education in Europe》1994,19(4):109-120

This report discusses the Workshop as a whole and reflects upon the points raised in the papers presented and the resulting discussions. First, the reasons for establishing non‐university higher education are presented and discussed, and then types of diversification, particularly vertical diversification, are examined. The most important questions raised, however, are those of how diversification is to be established and by what mechanisms it is to be controlled. The conclusions are mixed but stress that diversification should be undertaken very carefully and very democratically, care being taken both to recognize the value of the university tradition which has been evolving for centuries to avoid threats to flexibility and international recognition and mobility.  相似文献

Training and testing physical capacities for elite soccer players     

Hoff J 《Journal of sports sciences》2005,23(6):573-582

Elite soccer players spend a substantial amount of time trying to improve physical capacities, including aerobic endurance and strength and the strength derivatives of speed and power. The average oxygen uptake for international soccer teams ranges from 55 to 68 ml.kg-1.min-1 and the half-squat maximal strength from 120 to 180 kg. These values are similar to those found in other team sports. Recently, it has been shown that the heart's stroke volume is the element in the oxygen chain that mainly limits aerobic endurance for athletes. These findings have given rise to more intensive training interventions to secure high stroke volumes, which, in turn, have proved positive in changing both maximal oxygen consumption and soccer performance in terms of distance covered, contacts with the ball and number of sprints in a game. The training employed has consisted of 4x4-min "intervals" running uphill at 90-95% of maximal heart rate interspersed with 3 min jogging at 70% of maximal heart rate to facilitate removal of lactate. Research has revealed that a soccer-specific training routine with the ball might be as effective as plain running. Strength training to produce neural adaptations has been effective in changing not only strength in terms of "one-repetition maximum", but also sprinting velocity and jumping height, in elite soccer players without any change in body mass. The same training has also improved running economy and thus aerobic endurance performance. The training regimen used for a European Champions League team was 4x4 repetitions of half-squats with the emphasis on maximal mobilization of force in the concentric action.  相似文献
