An Exploration of the Relationship Among Teacher Efficacy,Collective Teacher Efficacy,and Goal Consensus

This study explored the relationships among individual teacher efficacy, collective teacher efficacy, and goal consensus/vision. Participants included 113 teachers of a high school located in the southwestern USA. During a teacher inservice meeting, teachers completed three surveys that measured the variables under study. Correlational and regression analyses were performed to examine the relationships among individual teacher efficacy, collective teacher efficacy, and goal consensus/vision. Collective teacher efficacy was found to be correlated with all of the other variables examined, but was most highly correlated with goal consensus/vision. Individual teacher efficacy, while related to collective teacher efficacy, was not found to be related to goal consensus/vision. Findings from this study suggest that, because individual teacher efficacy, collective teacher efficacy and goal consensus/vision are related, changing one could have an impact on the others. This revised version was published online in July 2006 with corrections to the Cover Date.     

基于ADAMS的双边驱动玻璃切割平台动态误差仿真分析

双边驱动玻璃切割平台驱动电机运动不同步时,平台运动部件会产生偏转振动,从而带来刀具运动及定位的动态误差,影响玻璃制件的加工质量和加工精度。通过刚柔耦合模型实现了双边驱动玻璃切割平台的仿真建模,利用动力学仿真分析软件ADAMS对非同步条件驱动下运动部件的动态误差进行了仿真分析,为双边驱动玻璃切割平台的设计和控制提供了理论依据。     

无机化学反应中的耦合现象

若一个化学反应的ΔγGθm >0 ,从热力学角度可以确定该反应在标准状态下不能自发进行 .改变反应条件 ,该反应可以转向自发也可能仍不能自发进行 ,在不改变其它反应条件下 ,利用一个能释放大量自由能的反应与之耦合 ,便可达到转化的目的 ,这就是化学反应中的耦合现象 .耦合现象与反应的能量密切相关

Effects of intensity on muscle-specific voluntary electromechanical delay and relaxation electromechanical delay

The purposes of this study were to examine: 1) the potential muscle-specific differences in voluntary electromechanical delay (EMD) and relaxation electromechanical delay (R-EMD), and 2) the effects of intensity on EMD and R-EMD during step incremental isometric muscle actions from 10 to 100% maximal voluntary isometric contraction (MVIC). EMD and R-EMD measures were calculated from the simultaneous assessments of electromyography, mechanomyography, and force production from the vastus lateralis (VL), vastus medialis (VM), and rectus femoris (RF) during step isometric muscle actions. There were no differences between the VL, VM, and RF for the voluntary EMD_E-M (onsets of the electromyographic to mechanomyographic signals), EMD_M-F (onsets the mechanomyographic to force production), or EMD_E-F (onsets of the electromyographic signal to force production) as well as R-EMD_E-M (cessation of electromyographic to mechanomyographic signal), R-EMD_M-F (cessation of mechanomyographic signal to force cessation), or R-EMD_E-F (cessation of electromyorgraphic signal to force cessation) at any intensity. There were decreases in all EMD and R-EMD measures with increases in intensity. The relative contributions from EMD_E-M and EMD_M-F to EMD_E-F as well as R-EMD_E-M and R-EMD_M-F to R-EMD_E-F remained similar across all intensities. The superficial muscles of the quadriceps femoris shared similar EMD and R-EMD measurements.     

《哀牢传》：民族交往需要的历史耦合

对西南边疆民族研究来说,《哀牢传》也是一篇很重要的民族学文献。哀牢归汉的根本动机可能是为了借助汉朝政府的赏赐与封号强化哀牢人的民族认同,保持哀牢民族的继续生存与发展。从民族交往需要来看,民族统一需要对异民族进行田野调查。哀牢民族的民族认同与汉朝政府的民族统一在民族学的沟通手段上形成了一种历史契合,因此,民族志也就必然会成为解决民族统一的最佳沟通手段。《哀牢传》的诞生就是民族交往历史耦合的需要所导致的。
