It is increasingly important to take international action for the avoidance of war and for the safeguarding of the human environment. For this there must be appropriate institutions and patterns of communication whose necessity and purposes are widely understood. This in turn presupposes building an increasing world dimension into school and university studies; otherwise coming generations will not be prepared for the world in which they will be living. For this a framework of concepts and ideas is needed, which have been adumbrated in the years since the Second World War, although there is a great need for clearer and more forceful thinking. We have to know what we wish to do and why it has become necessary. When this has been done we shall be in a better position to deal with the practical question of how our aims can be accomplished. 相似文献

This article presents a critical reflection on how we, instructors of a graduate-level course in higher education administration, sought to integrate theoretical and subject-matter content and research methodology. Our reflection, guided by autoethnography and teacher reflection, challenged both our assumptions about curriculum design and our process of designing and teaching the redesigned course. We found that our efforts to integrate course content and methodology differed from students’ prior experiences and resulted in a disconnection between their experience and the intended course learning objectives. Recommendations include understanding the degree program culture and students’ course expectations, using assignments that facilitate learning of both theory and methods, and balancing classroom discussion among theory, methodology, and the integration of the two. 相似文献

The home advantage is a widely acknowledged sporting phenomenon, especially in association football. Here, we examine the second leg home advantage, an effect that is discussed in the public domain but which has received very little scientific attention. The second leg home advantage effect occurs when on average teams are more likely to win a two-stage knock-out competition when they play at home in the second leg. That is, both teams have a home advantage but this advantage is significantly greater for the team that plays at home second. Examining data from three different European Cup football competitions spanning 51 years, we show that the second leg home advantage is a real phenomenon. The second leg home team has more than a 50% probability to qualify for the next round in the competition even after controlling for extra time and team ability as possible alternative explanations. The second leg home advantage appears, however, to have decreased significantly over the past decade. Possible reasons for its existence and subsequent decline are presented. 相似文献

The confined flow of red blood cells (RBCs) in microvasculature is essential for oxygen delivery to body tissues and has been extensively investigated in the literature, both in vivo and in vitro. One of the main problems still open in microcirculation is that flow resistance in microcapillaries in vivo is higher than that in vitro. This discrepancy has been attributed to the glycocalyx, a macromolecular layer lining the inner walls of vessels in vivo, but no direct experimental evidence of this hypothesis has been provided so far. Here, we investigate the flow behavior of RBCs in glass microcapillaries coated with a polymer brush (referred to as “hairy” microcapillaries as opposed to “bare” ones with no coating), an experimental model system of the glycocalyx. By high-speed microscopy imaging and image analysis, a velocity reduction of RBCs flowing in hairy microcapillaries as compared to bare ones is indeed found at the same pressure drop. Interestingly, such slowing down is larger than expected from lumen reduction due to the polymer brush and displays an on-off trend with a threshold around 70 nm of polymer brush dry thickness. Above this threshold, the presence of the polymer brush is associated with an increased RBC deformation, and RBC velocity is independent on polymer brush thickness (at the same pressure drop). In conclusion, this work provides direct support to the hypothesis that the glycocalyx is the main factor responsible of the higher flow resistance found in microcapillaries in vivo. 相似文献
