基于虚拟仪器的计算机控制步进电机系统的设计

在扫描探针显微镜系统中,本文采用基于虚拟仪器的计算机控制步进电机,控制它的正转、反转及启动和停止,从而实现样品与探针的自动逼近。利用计算机通过I/O接口来直接产生各种方波信号,采用L abV IEW编程完成控制算法,以此来实现步进电机运动,提高了逼近系统的自动化性能和控制精度。     

国际体育仲裁程序性问题之法律适用

在国际体育仲裁中,能否为体育纠纷寻求适合的法律适用,能否获得令人信服的解决结果,将决定着体育仲裁的公正与效率。作为体育纠 纷解决的新型手段,也作为仲裁世界的新兴疆域,国际体育仲裁既有着对仲裁传统形式尤其是国际商事仲裁的依从,也有着基于体育独有的社 会存在而顺应所生的创见。试循如上思路,以程序性问题的法律适用为核心,就国际体育仲裁尤其是强制性仲裁对传统仲裁法律适用规则之呼 应与变革进行梳理,以期在法律适用之相关问题的探讨中提出有益辨析。     

1999年全国体操锦标赛男子自由体操比赛浅析

目前在自由体操项目上, 运动员的成套动作出现了 “两多一少”现象, 这是规则导向的结果, 但并非动作发展的必然趋势。我国运动员在完成自由体操动作中, 尚存在着起评分偏低、训练水平欠缺和动作完成准确性等问题, 应予以重视     

A season-long team-building intervention: examining the effect of team goal setting on cohesion

The purpose of the current study was to determine whether the implementation of a season-long team-building intervention program using team goal setting increased perceptions of cohesion. The participants were 86 female high school basketball players from 8 teams. The teams were randomly assigned to either an experimental team goal-setting or control condition. Each participant completed the Group Environment Questionnaire (GEQ; Carron, Brawley, & Widmeyer, 2002; Carron, Widmeyer, & Brawley, 1985), which assessed cohesion at both the beginning and end of the season. Overall, the results revealed a significant multivariate effect, Pillai's trace F(12, 438) = 2.68, p = .002. Post hoc analyses showed that at the beginning of the season, athletes from both conditions did not differ in their perceptions of cohesion. However, at the end of the season, athletes in the team goal-setting condition held higher perceptions of cohesion than athletes in the control condition. Overall, the results indicated that team goal setting was an effective team-building tool for influencing cohesiveness in sport teams.

Constructivism: Does your practice match your conceptual framework?

Abstract

Though constructivism has been an epistemology espoused by early childhood educators since the field's inception; defining, understanding, and implementing a constructivist philosophy is challenging. This article includes an overview of constructivism, including the role of the learner and the teacher and the conditions that enhance learning. Also discussed will be distinct challenges that exist in the implementation of constructivism in a higher education setting. Practical strategies that universities have found to overcome these challenges are included.
