Cultural differences in the perception of critical interaction behaviors in global virtual teams     

Daphne M. Dekker  Christel G. Rutte  Peter T. Van den Berg   《Int J Intercult Relat》2008,32(5):441-452

We investigated whether members of virtual teams from the U.S., India, and Belgium perceived the same interaction behaviors to be critical for team functioning as Dutch members from an earlier study. Thirteen virtual team workers from the U.S., 11 from India, and 11 from Belgium were interviewed by means of the Critical Incident Technique Flanagan [Flanagan, J. C. (1954). The critical incident technique. Psychological Bulletin, 51, 327–358]. The total number of critical incidents from all countries was 493 and most incidents could be grouped into the same 13 categories as those found in the original Dutch study. However, the results showed that the distributions of the critical incidents from the American, Indian, and Belgian respondents differed from those of the Dutch. Indian and Belgian respondents also mentioned a new category of critical incidents: Respectfulness. The cultural differences were interpreted by means of Hofstede's [Hofstede, G. (2001). Cultures consequences: comparing values, behaviors, institutions, and organizations across nations (2nd ed.). Thousand Oaks, California, U.S.: SAGE Publications] dimensions.  相似文献   

循经感传激发经穴对心脏功能影响的研究进展     

张凡  杜书凯 《首都体育学院学报》2004,16(2):99-103

穴位针灸对心率、心功能和心脏本身的营养过程的调整作用，在人体试验与动物实验中，已经做了广泛的研究和观察，尤其是循经感传激发以促使“气至病所”提高针刺疗效，已广泛地被应用于临床治疗。我国传统的穴位针灸方法是否可以移植到运动生理学及运动医学利用中，并对运动员训练和比赛时生理应激过程起到积极的调整、改善和加速其恢复过程的作用，是非常值得研究与探讨的。  相似文献

The Global Partnership for Education’s evolving support to fragile and conflict-affected states     

《International Journal of Educational Development》2015

In this study, we trace the history of policy development within the Global Partnership for Education to discern the drivers behind the uptake of its shifting policies relating to education in fragile and conflict-affected states. In order to elucidate how and why this international organization has altered its policy stance and funding modalities, we employ a process tracing analysis of document and interview data. Moreover, we provide three country case studies of Global Partnership for Education financing to Liberia, Madagascar, and the Democratic Republic of the Congo.  相似文献   

基于P-范分布下的三维激光点位误差分布检验     

刘土生 《科技广场》2014,(10)

目前,在对三维激光点位误差模型进行推导的过程中,都是假设三维激光点位误差是服从正态分布的,而由于三维激光点位误差源与传统测量仪器中的误差源不同,同时外界环境对激光点位误差的影响也不相同,因此,不能直接断定点位误差服从正态分布,需要对其理论分析及数据统计分析验证。针对三维激光点位误差分布状况,本文对激光点位误差模型进行了推导,并通过大量数据统计分析验证了激光点位误差服从的分布状况。  相似文献   

The role of technological catch up and domestic market growth in the genesis of emerging country based multinationals     

Peter J. Buckley  Niron Hashai 《Research Policy》2014

The paper presents a model that evaluates how upgraded technological capabilities of emerging country based multinationals (EMNCs) and an increase in the domestic market size of large emerging countries affect value chain location choices and the competitiveness of emerging country based firms versus advanced country based ones. The model shows that, even without possessing a competitive advantage in terms of technology and/or brands, EMNCs from large or rapidly technologically advancing countries can become dominant players in the global system. The model highlights the central role of firm level technological intensity and product differentiation in determining the location of value chain activities as well as defining organisational boundaries. Empirical analysis of the location choices of the world's top multinationals from large advanced and emerging countries in 2010 supports the model's predictions.  相似文献   

中外优秀男子百米分段速度的研究     

谢慧松 《北京体育大学学报》2005,28(3):407-409

为了缩小中外男子百米速度的差距,本文通过文献资料法、影片拍摄法和数理统计法,对男子百米国际优秀水平组、国际水平组、中国组三组每10米段的平均速度进行了分析,通过研究结果对百米加速跑、途中跑和终点跑段落进行了重新划分;认为造成中国男子百米成绩差距的主要原因是:起跑至10 m的平均速度较慢,维持最大速度的能力差.  相似文献
