我国竞技体育,教练员与运动员关系好的不乏其人,他们努力训练,通力合作,为我国的竞技体育的腾飞作出了卓越的贡献,但也有些教练员与运动员关系不融洽,使运动员过早地离开运动场,失去了为国争光的机会。文章通过教练员和运动员关系的研究,旨在为提高竞技运动水平和教练员在选材、训练时提供参考。  相似文献   

Implementing Problem-Based Learning in Principal Training： The First Pilot Program in China     

Daming Feng 《美中教育评论》2005,2(3):13-19,12

In designing and implementing the pilot program of serving principal training, the author of this paper learnet the experience from what E. Bridges and E Hallinger did but didn＇t imitate fully, rather, created several new strategies because Chinese principals faced different situation from their American counterparts. The pilot program introduced and implemented the Problem-Based Learning （PBL） approach. The outcome of this pilot program shows： （1） PBL is a promising approach to serving principal training in China in casting off the traditional ＂chalk and talk＂ lecture approach. （2） The actual learning of trainees will happen prior to the classroom sessions if a trainer lets trainees participate the process of problem identification in pre-training stage. （3） PBL approach is much welcome and strong supported by local government and policymakers when the focal problem is related to implementation of current local nolicv.  相似文献

Writer identification approach based on bag of words with OBI features     

Amal Durou  Ibrahim Aref  Somaya Al-Maadeed  Ahmed Bouridane  Elhadj Benkhelifa 《Information processing & management》2019,56(2):354-366

Handwriter identification aims to simplify the task of forensic experts by providing them with semi-automated tools in order to enable them to narrow down the search to determine the final identification of an unknown handwritten sample. An identification algorithm aims to produce a list of predicted writers of the unknown handwritten sample ranked in terms of confidence measure metrics for use by the forensic expert will make the final decision.Most existing handwriter identification systems use either statistical or model-based approaches. To further improve the performances this paper proposes to deploy a combination of both approaches using Oriented Basic Image features and the concept of graphemes codebook. To reduce the resulting high dimensionality of the feature vector a Kernel Principal Component Analysis has been used. To gauge the effectiveness of the proposed method a performance analysis, using IAM dataset for English handwriting and ICFHR 2012 dataset for Arabic handwriting, has been carried out. The results obtained achieved an accuracy of 96% thus demonstrating its superiority when compared against similar techniques.  相似文献

Coordination pattern of baseball pitching among young pitchers of various ages and velocity levels     

Hsiu-Hui Chen  Chiang Liu  Wen-Wen Yang 《Journal of sports sciences》2016,34(17):1682-1690

This study compared the whole-body movement coordination of pitching among 72 baseball players of various ages and velocity levels. Participants were classified as senior, junior, and little according to their age, with each group comprising 24 players. The velocity levels of the high-velocity (the top eight) and low-velocity (the lowest eight) groups were classified according to their pitching velocity. During pitching, the coordinates of 15 markers attached to the major joints of the whole-body movement system were collected for analysis. Sixteen kinematic parameters were calculated to compare the groups and velocity levels. Principal component analysis (PCA) was conducted to quantify the coordination pattern of pitching movement. The results were as follows: (1) five position and two velocity parameters significantly differed among the age groups, and two position and one velocity parameters significantly differed between the high- and low-velocity groups. (2) The coordination patterns of pitching movement could be described using three components, of which the eigenvalues and contents varied according to age and velocity level. In conclusion, the senior and junior players showed greater elbow angular velocity, whereas the little players exhibited a wider shoulder angle only at the beginning of pitching. The players with high velocity exhibited higher trunk and shoulder rotation velocity. The variations among groups found using PCA and kinematics parameter analyses were consistent.  相似文献
