Purpose: Improvements in motor performance and coordination may be impacted by the interaction of practice and organismic constraints. It has been proposed that these aspects of motor learning are achieved at a different time rate: first, during placement of the events (performance), and second, segmental spatiotemporal relationships (coordination). We focused on the acquisition of the longswing in high bar as one basic skill in gymnastics. The aim of this study was to determine how longswing performance and coordination change to increase swing amplitude as age and expertise increase. Method: One hundred and thirteen male gymnasts were classified into 5 distinct age groups (G1, G2, G3, G4, and G5) on the basis of the national competition rules. Longswing performance (swing amplitude and event placements) and coordination (positive and negative areas in the continuous relative phase) were measured for each group. Results: Analyses of variance revealed that the adequate placement and coordination of the earlier events were achieved in younger groups (G1, G2), while later events and their coordination were accomplished by the older groups (G3 through G5). Conclusion: Our results suggested that the process of longswing acquisition, as age and expertise increase, follows a progression parallel to the temporal occurrence of the task events, instead of the proposed learning sequence of event placement first and then coordination. 相似文献

Motivational interviewing (MI) is an empirically based practice that provides counselors with methods for working with resistant and ambivalent clients. Whereas previous research has demonstrated the effectiveness of training current clinicians in this evidenced‐based practice, no research has investigated the efficacy of teaching MI to counselors‐in‐training who work with clients from the general population. The authors examined the effect of a student‐based training in MI for 43 graduate‐level counselor trainees using a quasi‐experimental controlled design. Statistical analyses based on pretest and posttest assessments revealed participants’ knowledge and skill in MI significantly improved in the treatment group. Implications for training future counselors and suggestions for additional research are explored. 相似文献

大学精神的坚守与失落——华南师范大学校史溯源 总被引：1，自引：0，他引：1

华南师范大学的历史，最早可以追溯到1933年创办的勷勤大学师范学院。至1949年的17年间，其办学方针体现出对大学精神从坚守到失落的转变。林砺儒主持学院的8年间，始终坚持了独立自主的办学路线，努力探索着高等师范教育之路。但在1941年8月林砺儒离开之后，理学院的独立自主办学路线难以为继，师范教育特色逐渐消退。这一转变导致在华南师范大学早期历史中大学精神的失落。 相似文献

试论现行汉英电子词典的分类与性能特征 总被引：1，自引：0，他引：1
廖海宏 《广东广播电视大学学报》2004,13(1):74-77
汉英电子词典日趋多样化，已成为数字化辞书的一大类型，具有强劲的发展势头。从目前的出版情况看，现行汉英电子词典载体丰富，形式多样，但词典的内容和功能在界限上呈现相对模糊性，同时随着计算机科技日臻完美，汉英电子词典逐步形成结构上的高度融合性，编纂上的数字化等性能特征。然而，值得注意的是，相对其它形式的电子词典汉英电子词典又呈现了一定的依附性。 相似文献

The cyclic oxidation behaviors of Fe-28Al-5Cr-O. 1Zr (at%) and Fe-28A15Cr-O. 5Nb (at%) alloys have been investigated in air
at high temperature. The results show that the distinctive whisker-like oxides were formed on the surface of Zr-containing
Fe3 Al based alloy after 500 hrs. cyclic oxidation at 800 °C and 1000 °C. The results also indicate that the addition of small
amount of Zr to Fe3 Al based alloy can improve its adherence strength between the oxides and metal substrate and is beneficial to the oxidation
resistance. However, for the Nb-containing Fe3 Al based alloy, porous convoluted oxides were formed after 350 hrs. cyclic oxidation at 1000°C, and this type of oxides didn’t
not contribute to the oxidation resistance. 相似文献
