激励视角下我国公务员薪酬制度的路径再选择     

杨蕾  李鲁红 《唐山职业技术学院学报》2007,(1)

目前我国公务员薪酬管理在薪酬水平、薪酬支付制度、职位分类以及法制规范等方面都存在诸多问题。因此应该加快公务员薪酬管理的法制化建设、工资等级实行波段宽化及公务员薪酬货币化和显现化、设置科学的公务员职位分类制度。  相似文献   

基于动力学模型的四轮全向机器人滑模轨迹跟踪控制     

李运奇杨宜民  王建彬 《科技广场》2014,(1):89-93

四轮全向机器人是一个复杂的四维冗余系统,其轨迹跟踪控制性能极易受到模型不确定性及外界干扰的影响。针对这一问题,本文提出一种基于动力学模型的四轮全向机器人滑模轨迹跟踪控制方法。首先,通过输入变换将复杂的四维冗余机器人系统模型转化为三维模型,然后针对模型不确定性及外界扰动,采用滑模控制算法进行轨迹跟踪控制。仿真结果表明,该方法能够有效抑制外界干扰,同时降低模型不确定性的影响,机器人能够很好地跟踪期望轨迹,跟踪速度快,跟踪精度高。  相似文献

The effect of cooperative and individualistic learning experiences on positive and negative cross-handicap relationships     

Stuart Yager  Roger T. Johnson  David W. Johnson  Bill Snider 《Contemporary educational psychology》1985,10(2):127-138

The effects of cooperative and individualistic learning contingencies on interpersonal attraction, social acceptability, and self-esteem between handicapped and nonhandicapped fourth-grade students were tracked and compared. Sixty-nine students were assigned to conditions on a stratified random basis controlling for handicap, sex, and age. They participated in the study for 45 min a day for 54 instructional days during science class. Nonhandicapped peer ratings of the social acceptability of each handicapped student and several attitude measures were obtained four separate times at 18-day intervals. The results indicate that continued use of cooperative learning contingencies promote positive growth in interpersonal attraction, social acceptability, and self-esteem between handicapped and nonhandicapped students. The results also indicate that when cooperative learning contingencies are replaced with individualized learning contingencies, decay in the above-mentioned variables occurs.  相似文献

“非直即斜”视角下乒乓球比赛变线特征、效果及发展动态研究          下载免费PDF全文

张赛强 《河北体育学院学报》2017,31(6):81-86

运用文献资料法、专家访谈法、录像观察法和数理统计法，以“非直即斜”为视角对世界优秀男子乒乓球运动员的变线特征、效果及其发展动态进行研究。认为：①非变线是运动员技战术运用的主要形式，变线是其辅助形式；变线和非变线在比赛制胜中发挥着几乎同等重要的作用，但变线的得分效果明显优于非变线。②逢直变斜和逢斜变斜是运动员的主要变线类型选择，在比赛中发挥着主导作用，而逢斜变直则发挥着战略上的牵制作用；三种变线类型间无明显得分效果差异。③以“非直即斜”为视角对变线形式进行分类能较为深入地揭示不同变线类型的作用和动态变化规律；各赛事中各类变线形式的运用情况和运用效果始终处于变化之中，变线调整以逢直变斜和逢斜变斜为主；进入新球阶段后，逢斜变斜类变线形式的得分效果有逐渐上升之势，逢直变斜的得分效果则表现出缓缓下降之势。以期为我国乒乓球队的科学训练和参赛提供参考  相似文献   

Media Exposure and Thin-Ideal Internalization in the Drive for Thinness in Japanese Women     

Shinichi Saito 《Communication Research Reports》2017,34(2):89-97

Focusing mainly on the roles of media exposure and thin-ideal internalization, this study attempts to extend the findings of previous studies conducted in other countries. A structural equation model with maximum likelihood estimation was performed to test the hypothesized path model. The fit indices indicated that the path model provided an acceptable fit. The results revealed that the influence of fashion magazine reading on the drive for thinness is mediated via thin-ideal internalization. Thus, heavier readers of fashion magazines were more likely to exhibit a greater drive for thinness via internalization of the thin ideal. The results were generally consistent with findings from previous studies conducted in other countries, confirming the cross-cultural importance of the process of thin-ideal internalization in the study of the drive for thinness among young women.  相似文献
