This paper explores what factors determine the nature, extent, and location of Japanese multinationals’ R&D activities abroad. Taking advantage of a rich micro-level dataset from the survey on Japanese overseas subsidiaries, the study distinguishes between two types of overseas R&D: basic/applied research and development/design. We find several differences between the determinants of those R&D activities. These differences confirm the view that basic/applied research of overseas subsidiaries aims at the exploitation of foreign advanced knowledge, whereas their development/design activities are mostly influenced by the market size of the host country. Our results provide a convincing and comprehensive explanation of the geographical distribution of overseas R&D by Japanese MNEs.  相似文献

There is a need for reliable analysis techniques for kinetic data for coaches and sport scientists who employ athlete monitoring practices. The purpose of the study was: (1) to determine intra- and inter-rater reliability within a manual-based kinetic analysis program; and (2) to determine test-retest reliability of an algorithm-based kinetic analysis program. Five independent raters used a manual analysis program to analyse 100 isometric mid-thigh pull (IMTP) trials obtained from previously collected data. Each trial was analysed three times. The same IMTP trials were analysed using an algorithm-based analysis software. Variables measured were peak force, rate of force development from 0 to 50 ms (RFD50) and RFD from 0 to 200 ms (RFD200). Intraclass correlation coefficients (ICC) and coefficient of variation (CV) were used to assess intra- and inter-rater reliability. Nearly perfect reliability was observed for the manual-based (ICC > 0.92). However, poor intra- and inter-rater CV was observed for RFD (CV > 16.25% and CV > 32.27%, respectively). The algorithm-based method resulted in perfect reliability in all measurements (ICC = 1.0, CV = 0%). While manual methods of kinetic analysis may provide sufficient reliability, the perfect reliability observed within the algorithm-based method in the current study suggest it is a superior method for use in athlete monitoring programs.  相似文献

This essay is an attempt to investigate and discuss the significance and validity of researching Buddhist preaching as the main undercurrent of Japanese rhetorical communication practices. The argument first points out contemporary rhetoricians' weaknesses in research, and proceeds to discuss the importance of viewing preaching as a form of rhetorical communication. It then describes historical backgrounds of Japanese Buddhist preaching, and finally analyzes the preaching principles in comparison with the five canons of Western rhetoric, stressing the value of studying Buddhist preaching from the rhetorical perspective.  相似文献

Because of the ill-posedness of grasping, one feasible method must be selected from possible strategies. Among many factors, this paper focuses on the posture of an object: which object direction is best when it is grasped. Then, the object is assumed to be held with three points where the contact forces can be generated in any directions. To evaluate the object posture, the norm of contact force vector consisting of the normal and tangential forces is selected. Consequently, the contact force becomes minimal when the center of mass of the grasped object and the centroid of the triangle composed by three contact points are aligned in the gravitational direction.  相似文献

Aerodynamic properties of an archery arrow   总被引:1,自引:0,他引:1  
Two support-interference-free measurements of aerodynamic forces exerted on an archery arrow (A/C/E; Easton Technical Products) are described. The first measurement is conducted in a wind tunnel with JAXA’s 60 cm Magnetic Suspension and Balance System, in which an arrow is suspended and balanced by magnetic force against gravity. The maximum wind velocity is 45 m/s, which is less than a typical velocity of an arrow (about 60 m/s) shot by an archer. The boundary layer of the arrow remains laminar in the measured Re number range (4.0 × 103 < Re < 1.5 × 104), and the drag coefficient is about 1.5 for Re > 1.0 × 104. The second measurement is performed by a free flight experiment. Using two high-speed video cameras, we record the trajectory of an archery arrow and analyze its velocity decay rate, from which the drag coefficient is determined. In order to investigate Re number dependence of the drag coefficient in a wider range (9.0 × 103 < Re < 2.4 × 104), we have developed an arrow-shooting system using compressed air as a power source, which launches the A/C/E arrow at an arbitrary velocity up to 75 m/s. We attach two points (piles) of different type (streamlined and bullet) to the arrow-nose. The boundary layer is laminar for both points for Re less than about 1.2 × 104. It becomes turbulent for Re larger than 1.2 × 104 and the drag coefficient increases to about 2.6, when the bullet point is attached. In the same Re range, two values of drag coefficient are found for the streamlined point, of which the lower value is about 1.6 (laminar boundary layer) and the larger value is about 2.6 (turbulent boundary layer), confirming that the point-shape has a crucial influence on the laminar to turbulent transition of the boundary layer.  相似文献

Recent policy debates surrounding Japan??s graduate education raise a serious skepticism in the validity of its ??research-based?? or ??learning-by-doing?? training approach that these institutions have uniquely established. Proponents of reform suggest drastic restructuring of the graduate programs by replacing the experience-based mentoring aspect with more systematic education that blends an array of coursework and examinations. However, whether such a coursework-based model of graduate training will successfully function without sacrificing the traditional virtue of Japanese practices is an unsubstantiated matter. Japanese graduate schools have produced scientists who have made immense contributions to the advancement in our scientific knowledge. Policy makers and academia in Japan should humbly acknowledge this fact and prudently determine what aspects of their educational content should be reformed and what should be retained. In order to do this, the merits and demerits of alternative models must be clearly understood. The objective of this study is to affirm both the strengths and weaknesses of the traditional approach that Japanese universities need to consider preserving and eliminating, in order to capitalize on their institutional heritage while also building in the educational caliber of the rigorous US graduate training model in the reforming process.  相似文献
